  • BACKGROUND
  • [0017]
    Known surgical staplers include an end effector that simultaneously makes a longitudinal incision in tissue and applies lines of staples on opposing sides of the incision. The end effector includes a pair of cooperating jaw members that, if the instrument is intended for endoscopic or laparoscopic applications, are capable of passing through a cannula passageway. One of the jaw members receives a staple cartridge having at least two laterally spaced rows of staples. The other jaw member defines an anvil having staple-forming pockets aligned with the rows of staples in the cartridge. The instrument includes a plurality of reciprocating wedges which, when driven distally, pass through openings in the staple cartridge and engage drivers supporting the staples to effect the firing of the staples toward the anvil.

  • DETAILED DESCRIPTION
  • [0048]
    FIGS. 1 and 2 depict a surgical cutting and fastening instrument 10 according to various embodiments of the present invention. The illustrated embodiment is an endoscopic surgical instrument 10 and in general, the embodiments of the instrument 10 described herein are endoscopic surgical cutting and fastening instruments. It should be noted, however, that according to other embodiments of the present invention, the instrument 10 may be a non-endoscopic surgical cutting and fastening instrument, such as a laparoscopic instrument.
  • [0049]
    The surgical instrument 10 depicted in FIGS. 1 and 2 comprises a handle 6, a shaft 8, and an articulating end effector 12 pivotally connected to the shaft 8 at an articulation pivot 14. An articulation control 16 may be provided adjacent to the handle 6 to effect rotation of the end effector 12 about the articulation pivot 14. It will be appreciated that various embodiments may include a non-pivoting end effector, and therefore may not have an articulation pivot 14 or articulation control 16. Also, in the illustrated embodiment, the end effector 12 is configured to act as an endocutter for clamping, severing and stapling tissue, although, in other embodiments, different types of end effectors may be used, such as end effectors for other types of surgical devices, such as graspers, cutters, staplers, clip appliers, access devices, drug/gene therapy devices, ultrasound, RF or laser devices, etc.
  • [0050]
    The handle 6 of the instrument 10 may include a closure trigger 18 and a firing trigger 20 for actuating the end effector 12. It will be appreciated that instruments having end effectors directed to different surgical tasks may have different numbers or types of triggers or other suitable controls for operating the end effector 12. The end effector 12 is shown separated from the handle 6 by a preferably elongate shaft 8. In one embodiment, a clinician or operator of the instrument 10 may articulate the end effector 12 relative to the shaft 8 by utilizing the articulation control 16, as described in more detail in U.S. patent application Ser. No. 11/329,020, filed Jan. 10, 2006, entitled SURGICAL INSTRUMENT HAVING AN ARTICULATING END EFFECTOR, now U.S. Pat. No. 7,670,334, which is incorporated herein by reference.
  • [0051]
    The end effector 12 includes in this example, among other things, a staple channel 22 and a pivotally translatable clamping member, such as an anvil 24, which are maintained at a spacing that assures effective stapling and severing of tissue clamped in the end effector 12. The handle 6 includes a pistol grip 26 toward which a closure trigger 18 is pivotally drawn by the clinician to cause clamping or closing of the anvil 24 towards the staple channel 22 of the end effector 12 to thereby clamp tissue positioned between the anvil 24 and channel 22. The firing trigger 20 is farther outboard of the closure trigger 18. Once the closure trigger 18 is locked in the closure position as further described below, the firing trigger 20 may rotate slightly toward the pistol grip 26 so that it can be reached by the operator using one hand. Then the operator may pivotally draw the firing trigger 20 toward the pistol grip 26 to cause the stapling and severing of clamped tissue in the end effector 12. In other embodiments, different types of clamping members besides the anvil 24 could be used, such as, for example, an opposing jaw, etc.
  • [0052]
    It will be appreciated that the terms “proximal” and “distal” are used herein with reference to a clinician gripping the handle 6 of an instrument 10. Thus, the end effector 12 is distal with respect to the more proximal handle 6. It will be further appreciated that, for convenience and clarity, spatial terms such as “vertical” and “horizontal” are used herein with respect to the drawings. However, surgical instruments are used in many orientations and positions, and these terms are not intended to be limiting and absolute.
  • [0053]
    The closure trigger 18 may be actuated first. Once the clinician is satisfied with the positioning of the end effector 12, the clinician may draw back the closure trigger 18 to its fully closed, locked position proximate to the pistol grip 26. The firing trigger 20 may then be actuated. The firing trigger 20 returns to the open position (shown in FIGS. 1 and 2) when the clinician removes pressure, as described more fully below. A release button on the handle 6, when depressed may release the locked closure trigger 18. The release button may be implemented in various forms such as, for example, release button 30 shown in FIGS. 42-43, slide release button 160 shown in FIG. 14, and/or button 172 shown in FIG. 16.
  • [0054]
    FIGS. 3-6 show embodiments of a rotary-driven end effector 12 and shaft 8 according to various embodiments. FIG. 3 is an exploded view of the end effector 12 according to various embodiments. As shown in the illustrated embodiment, the end effector 12 may include, in addition to the previously-mentioned channel 22 and anvil 24, a cutting instrument 32, a sled 33, a staple cartridge 34 that is removably seated in the channel 22, and a helical screw shaft 36. The cutting instrument 32 may be, for example, a knife. The anvil 24 may be pivotably opened and closed at pivot pins 25 connected to the proximate end of the channel 22. The anvil 24 may also include a tab 27 at its proximate end that is inserted into a component of the mechanical closure system (described further below) to open and close the anvil 24. When the closure trigger 18 is actuated, that is, drawn in by a user of the instrument 10, the anvil 24 may pivot about the pivot pins 25 into the clamped or closed position. If clamping of the end effector 12 is satisfactory, the operator may actuate the firing trigger 20, which, as explained in more detail below, causes the knife 32 and sled 33 to travel longitudinally along the channel 22, thereby cutting tissue clamped within the end effector 12. The movement of the sled 33 along the channel 22 causes the staples (not shown) of the staple cartridge 34 to be driven through the severed tissue and against the closed anvil 24, which turns the staples to fasten the severed tissue. In various embodiments, the sled 33 may be an integral component of the cartridge 34. U.S. Pat. No. 6,978,921, entitled SURGICAL STAPLING INSTRUMENT INCORPORATING AN E-BEAM FIRING MECHANISM, which is incorporated herein by reference, provides more details about such two-stroke cutting and fastening instruments. The sled 33 may be part of the cartridge 34, such that when the knife 32 retracts following the cutting operation, the sled 33 does not retract.
  • [0055]
    It should be noted that although the embodiments of the instrument 10 described herein employ an end effector 12 that staples the severed tissue, in other embodiments different techniques for fastening or sealing the severed tissue may be used. For example, end effectors that use RF energy or adhesives to fasten the severed tissue may also be used. U.S. Pat. No. 5,709,680 entitled ELECTROSURGICAL HEMOSTATIC DEVICE, and U.S. Pat. No. 5,688,270 entitled ELECTROSURGICAL HEMOSTATIC DEVICE WITH RECESSED AND/OR OFFSET ELECTRODES, which are incorporated herein by reference, disclose an endoscopic cutting instrument that uses RF energy to seal the severed tissue. U.S. patent application Ser. No. 11/267,811, now U.S. Pat. No. 7,673,783 and U.S. patent application Ser. No. 11/267,383, now U.S. Pat. No. 7,607,557, which are also incorporated herein by reference, disclose cutting instruments that uses adhesives to fasten the severed tissue. Accordingly, although the description herein refers to cutting/stapling operations and the like below, it should be recognized that this is an exemplary embodiment and is not meant to be limiting. Other tissue fastening techniques may also be used.
  • [0056]
    FIGS. 4 and 5 are exploded views and FIG. 6 is a side view of the end effector 12 and shaft 8 according to various embodiments. As shown in the illustrated embodiment, the shaft 8 may include a proximate closure tube 40 and a distal closure tube 42 pivotably linked by pivot links 44. The distal closure tube 42 includes an opening 45 into which the tab 27 on the anvil 24 is inserted in order to open and close the anvil 24, as further described below. Disposed inside the closure tubes 40, 42 may be a proximate spine tube 46. Disposed inside the proximate spine tube 46 may be a main rotational (or proximate) drive shaft 48 that communicates with a secondary (or distal) drive shaft 50 via a bevel gear assembly 52. The secondary drive shaft 50 is connected to a drive gear 54 that engages a proximate drive gear 56 of the helical screw shaft 36. The vertical bevel gear 52 b may sit and pivot in an opening 57 in the distal end of the proximate spine tube 46. A distal spine tube 58 may be used to enclose the secondary drive shaft 50 and the drive gears 54, 56. Collectively, the main drive shaft 48, the secondary drive shaft 50, and the articulation assembly (e.g., the bevel gear assembly 52 a-c) are sometimes referred to herein as the “main drive shaft assembly.”
  • [0057]
    A bearing 38, positioned at a distal end of the staple channel 22, receives the helical drive screw 36, allowing the helical drive screw 36 to freely rotate with respect to the channel 22. The helical screw shaft 36 may interface a threaded opening (not shown) of the knife 32 such that rotation of the shaft 36 causes the knife 32 to translate distally or proximally (depending on the direction of the rotation) through the staple channel 22. Accordingly, when the main drive shaft 48 is caused to rotate by actuation of the firing trigger 20 (as explained in more detail below), the bevel gear assembly 52 a-c causes the secondary drive shaft 50 to rotate, which in turn, because of the engagement of the drive gears 54, 56, causes the helical screw shaft 36 to rotate, which causes the knife driving member 32 to travel longitudinally along the channel 22 to cut any tissue clamped within the end effector 12. The sled 33 may be made of, for example, plastic, and may have a sloped distal surface. As the sled 33 traverses the channel 22, the sloped forward surface may push up or drive the staples in the staple cartridge 34 through the clamped tissue and against the anvil 24. The anvil 24 turns the staples, thereby stapling the severed tissue. When the knife 32 is retracted, the knife 32 and sled 33 may become disengaged, thereby leaving the sled 33 at the distal end of the channel 22.
  • [0058]
    Because of the lack of user feedback for the cutting/stapling operation, there is a general lack of acceptance among physicians of motor-driven endocutters where the cutting/stapling operation is actuated by merely pressing a button. In contrast, embodiments of the present invention provide a motor-driven endocutter with user-feedback of the deployment, force and/or position of the cutting instrument in the end effector.
  • [0059]
    FIGS. 7-10 illustrate an exemplary embodiment of a motor-driven endocutter, and in particular the handle thereof, that provides user-feedback regarding the deployment and loading force of the cutting instrument 32 in the end effector 12. In addition, the embodiment may use power provided by the user in retracting the firing trigger 20 to power the device (a so-called “power assist” mode). The embodiment may be used with the rotary driven end effector 12 and shaft 8 embodiments described above. As shown in the illustrated embodiment, the handle 6 includes exterior lower side pieces 59, 60 and exterior upper side pieces 61, 62 that fit together to form, in general, the exterior of the handle 6. A battery 64, such as a Li ion battery, may be provided in the pistol grip portion 26 of the handle 6. The battery 64 powers a motor 65 disposed in an upper portion of the pistol grip portion 26 of the handle 6. According to various embodiments, the motor 65 may be a DC brushed driving motor having a maximum rotation of, approximately, 5000 RPM. The motor 65 may drive a 90° bevel gear assembly 66 comprising a first bevel gear 68 and a second bevel gear 70. The bevel gear assembly 66 may drive a planetary gear assembly 72. The planetary gear assembly 72 may include a pinion gear 74 connected to a drive shaft 76. The pinion gear 74 may drive a mating ring gear 78 that drives a helical gear drum 80 via a drive shaft 82. A ring 84 may be threaded on the helical gear drum 80. Thus, when the motor 65 rotates, the ring 84 is caused to travel along the helical gear drum 80 by means of the interposed bevel gear assembly 66, planetary gear assembly 72 and ring gear 78.
  • [0060]
    The handle 6 may also include a run motor sensor 110 (see FIG. 10) in communication with the firing trigger 20 to detect when the firing trigger 20 has been drawn in (or “closed”) toward the pistol grip portion 26 of the handle 6 by the operator to thereby actuate the cutting/stapling operation by the end effector 12. The sensor 110 may be a proportional sensor such as, for example, a rheostat or variable resistor. When the firing trigger 20 is drawn in, the sensor 110 detects the movement, and sends an electrical signal indicative of the voltage (or power) to be supplied to the motor 65. When the sensor 110 is a variable resistor or the like, the rotation of the motor 65 may be generally proportional to the amount of movement of the firing trigger 20. That is, if the operator only draws or closes the firing trigger 20 in a little bit, the rotation of the motor 65 is relatively low. When the firing trigger 20 is fully drawn in (or in the fully closed position), the rotation of the motor 65 is at its maximum. In other words, the harder the user pulls on the firing trigger 20, the more voltage is applied to the motor 65, causing greater rates of rotation.
  • [0061]
    The handle 6 may include a middle handle piece 104 adjacent to the upper portion of the firing trigger 20. The handle 6 also may comprise a bias spring 112 connected between posts on the middle handle piece 104 and the firing trigger 20. The bias spring 112 may bias the firing trigger 20 to its fully open position. In that way, when the operator releases the firing trigger 20, the bias spring 112 will pull the firing trigger 20 to its open position, thereby removing actuation of the sensor 110, thereby stopping rotation of the motor 65. Moreover, by virtue of the bias spring 112, any time a user closes the firing trigger 20, the user will experience resistance to the closing operation, thereby providing the user with feedback as to the amount of rotation exerted by the motor 65. Further, the operator could stop retracting the firing trigger 20 to thereby remove force from the sensor 100, to thereby stop the motor 65. As such, the user may stop the deployment of the end effector 12, thereby providing a measure of control of the cutting/fastening operation to the operator.
  • [0062]
    The distal end of the helical gear drum 80 includes a distal drive shaft 120 that drives a ring gear 122, which mates with a pinion gear 124. The pinion gear 124 is connected to the main drive shaft 48 of the main drive shaft assembly. In that way, rotation of the motor 65 causes the main drive shaft assembly to rotate, which causes actuation of the end effector 12, as described above.
  • [0063]
    The ring 84 threaded on the helical gear drum 80 may include a post 86 that is disposed within a slot 88 of a slotted arm 90. The slotted arm 90 has an opening 92 its opposite end 94 that receives a pivot pin 96 that is connected between the handle exterior side pieces 59, 60. The pivot pin 96 is also disposed through an opening 100 in the firing trigger 20 and an opening 102 in the middle handle piece 104.
  • [0064]
    In addition, the handle 6 may include a reverse motor sensor (or end-of-stroke sensor) 130 and a stop motor (or beginning-of-stroke) sensor 142. In various embodiments, the reverse motor sensor 130 may be a limit switch located at the distal end of the helical gear drum 80 such that the ring 84 threaded on the helical gear drum 80 contacts and trips the reverse motor sensor 130 when the ring 84 reaches the distal end of the helical gear drum 80. The reverse motor sensor 130, when activated, sends a signal to the motor 65 to reverse its rotation direction, thereby withdrawing the knife 32 of the end effector 12 following the cutting operation.
  • [0065]
    The stop motor sensor 142 may be, for example, a normally-closed limit switch. In various embodiments, it may be located at the proximate end of the helical gear drum 80 so that the ring 84 trips the switch 142 when the ring 84 reaches the proximate end of the helical gear drum 80.
  • [0066]
    In operation, when an operator of the instrument 10 pulls back the firing trigger 20, the sensor 110 detects the deployment of the firing trigger 20 and sends a signal to the motor 65 to cause forward rotation of the motor 65 at, for example, a rate proportional to how hard the operator pulls back the firing trigger 20. The forward rotation of the motor 65 in turn causes the ring gear 78 at the distal end of the planetary gear assembly 72 to rotate, thereby causing the helical gear drum 80 to rotate, causing the ring 84 threaded on the helical gear drum 80 to travel distally along the helical gear drum 80. The rotation of the helical gear drum 80 also drives the main drive shaft assembly as described above, which in turn causes deployment of the knife 32 in the end effector 12. That is, the knife 32 and sled 33 are caused to traverse the channel 22 longitudinally, thereby cutting tissue clamped in the end effector 12. Also, the stapling operation of the end effector 12 is caused to happen in embodiments where a stapling-type end effector 12 is used.
  • [0067]
    By the time the cutting/stapling operation of the end effector 12 is complete, the ring 84 on the helical gear drum 80 will have reached the distal end of the helical gear drum 80, thereby causing the reverse motor sensor 130 to be tripped, which sends a signal to the motor 65 to cause the motor 65 to reverse its rotation. This in turn causes the knife 32 to retract, and also causes the ring 84 on the helical gear drum 80 to move back to the proximate end of the helical gear drum 80.
  • [0068]
    The middle handle piece 104 includes a backside shoulder 106 that engages the slotted arm 90 as best shown in FIGS. 8 and 9. The middle handle piece 104 also has a forward motion stop 107 that engages the firing trigger 20. The movement of the slotted arm 90 is controlled, as explained above, by rotation of the motor 65. When the slotted arm 90 rotates counter clockwise as the ring 84 travels from the proximate end of the helical gear drum 80 to the distal end, the middle handle piece 104 will be free to rotate counter clockwise. Thus, as the user draws in the firing trigger 20, the firing trigger 20 will engage the forward motion stop 107 of the middle handle piece 104, causing the middle handle piece 104 to rotate counter clockwise. Due to the backside shoulder 106 engaging the slotted arm 90, however, the middle handle piece 104 will only be able to rotate counter clockwise as far as the slotted arm 90 permits. In that way, if the motor 65 should stop rotating for some reason, the slotted arm 90 will stop rotating, and the user will not be able to further draw in the firing trigger 20 because the middle handle piece 104 will not be free to rotate counter clockwise due to the slotted arm 90.
  • [0069]
    FIGS. 10A and 10B illustrate two states of a variable sensor that may be used as the run motor sensor 110 according to various embodiments of the present invention. The sensor 110 may include a face portion 280, a first electrode (A) 282, a second electrode (B) 284, and a compressible dielectric material 286 between the electrodes 282, 284, such as, for example, an electroactive polymer (EAP). The sensor 110 may be positioned such that the face portion 280 contacts the firing trigger 20 when retracted. Accordingly, when the firing trigger 20 is retracted, the dielectric material 286 is compressed, as shown in FIG. 10B, such that the electrodes 282, 284 are closer together. Since the distance “b” between the electrodes 282, 284 is directly related to the impedance between the electrodes 282, 284, the greater the distance the more impedance, and the closer the distance the less impedance. In that way, the amount that the dielectric material 286 is compressed due to retraction of the firing trigger 20 (denoted as force “F” in FIG. 42) is proportional to the impedance between the electrodes 282, 284, which can be used to proportionally control the motor 65.
  • [0070]
    Components of an exemplary closure system for closing (or clamping) the anvil 24 of the end effector 12 by retracting the closure trigger 18 are also shown in FIGS. 7-10. In the illustrated embodiment, the closure system includes a yoke 250 connected to the closure trigger 18 by a pivot pin 251 inserted through aligned openings in both the closure trigger 18 and the yoke 250. A pivot pin 252, about which the closure trigger 18 pivots, is inserted through another opening in the closure trigger 18 which is offset from where the pin 251 is inserted through the closure trigger 18. Thus, retraction of the closure trigger 18 causes the upper part of the closure trigger 18, to which the yoke 250 is attached via the pin 251, to rotate counterclockwise. The distal end of the yoke 250 is connected, via a pin 254, to a first closure bracket 256. The first closure bracket 256 connects to a second closure bracket 258. Collectively, the closure brackets 256, 258 define an opening in which the proximal end of the proximate closure tube 40 (see FIG. 4) is seated and held such that longitudinal movement of the closure brackets 256, 258 causes longitudinal motion by the proximate closure tube 40. The instrument 10 also includes a closure rod 260 disposed inside the proximate closure tube 40. The closure rod 260 may include a window 261 into which a post 263 on one of the handle exterior pieces, such as exterior lower side piece 59 in the illustrated embodiment, is disposed to fixedly connect the closure rod 260 to the handle 6. In that way, the proximate closure tube 40 is capable of moving longitudinally relative to the closure rod 260. The closure rod 260 may also include a distal collar 267 that fits into a cavity 269 in proximate spine tube 46 and is retained therein by a cap 271 (see FIG. 4).
  • [0071]
    In operation, when the yoke 250 rotates due to retraction of the closure trigger 18, the closure brackets 256, 258 cause the proximate closure tube 40 to move distally (i.e., away from the handle end of the instrument 10), which causes the distal closure tube 42 to move distally, which causes the anvil 24 to rotate about the pivot pins 25 into the clamped or closed position. When the closure trigger 18 is unlocked from the locked position, the proximate closure tube 40 is caused to slide proximally, which causes the distal closure tube 42 to slide proximally, which, by virtue of the tab 27 being inserted in the window 45 of the distal closure tube 42, causes the anvil 24 to pivot about the pivot pins 25 into the open or unclamped position. In that way, by retracting and locking the closure trigger 18, an operator may clamp tissue between the anvil 24 and channel 22, and may unclamp the tissue following the cutting/stapling operation by unlocking the closure trigger 18 from the locked position.
  • [0072]
    FIG. 11 is a schematic diagram of an electrical circuit of the instrument 10 according to various embodiments of the present invention. When an operator initially pulls in the firing trigger 20 after locking the closure trigger 18, the sensor 110 is activated, allowing current to flow therethrough. If the normally-open reverse motor sensor switch 130 is open (meaning the end of the end effector stroke has not been reached), current will flow to a single pole, double throw relay 132. Since the reverse motor sensor switch 130 is not closed, the inductor 134 of the relay 132 will not be energized, so the relay 132 will be in its non-energized state. The circuit also includes a cartridge lockout sensor 136. If the end effector 12 includes a staple cartridge 34, the sensor 136 will be in the closed state, allowing current to flow. Otherwise, if the end effector 12 does not include a staple cartridge 34, the sensor 136 will be open, thereby preventing the battery 64 from powering the motor 65.
  • [0073]
    When the staple cartridge 34 is present, the sensor 136 is closed, which energizes a single pole, single throw relay 138. When the relay 138 is energized, current flows through the relay 136, through the variable resistor sensor 110, and to the motor 65 via a double pole, double throw relay 140, thereby powering the motor 65 and allowing it to rotate in the forward direction.
  • [0074]
    When the end effector 12 reaches the end of its stroke, the reverse motor sensor 130 will be activated, thereby closing the switch 130 and energizing the relay 132. This causes the relay 132 to assume its energized state (not shown in FIG. 11), which causes current to bypass the cartridge lockout sensor 136 and variable resistor 110, and instead causes current to flow to both the normally-closed double pole, double throw relay 140 and back to the motor 65, but in a manner, via the relay 140, that causes the motor 65 to reverse its rotational direction.
  • [0075]
    Because the stop motor sensor switch 142 is normally-closed, current will flow back to the relay 132 to keep it closed until the switch 142 opens. When the knife 32 is fully retracted, the stop motor sensor switch 142 is activated, causing the switch 142 to open, thereby removing power from the motor 65.
  • [0076]
    FIG. 11A is a schematic diagram of an electrical circuit of the instrument 10 according to various embodiments of the present invention. When an operator initially pulls in the firing trigger 20 after locking the closure trigger 18, the sensor 110 is activated, allowing current to flow therethrough. If the normally-open reverse motor sensor switch 130 is open (meaning the end of the end effector stroke has not been reached), current will flow to a single pole, double throw relay 132. Since the reverse motor sensor switch 130 is not closed, coil 134 of the relay 132 will not be energized, so the relay 132 will be in its de-energized state. The electrical circuit further includes lockout sensor switches 136 a-d collectively defining an interlock circuit 137 through which current from the relay 132, when de-energized, must pass in order for electrical operation of the motor 65 to be initiated. Each lockout sensor switch 136 a-d is configured to maintain an open (i.e., non-conductive) switch state or a closed (i.e., conductive) switch state responsive to the presence or absence, respectively, of a corresponding condition. Any of the corresponding conditions, if present when the instrument 10 is fired, may result in an unsatisfactory cutting and stapling operation and/or damage to the instrument 10. Conditions to which the lockout sensor switches 136 a-d may respond include, for example, the absence of the staple cartridge 34 in the channel 22, the presence of a spent (e.g., previously fired) staple cartridge 34 in the channel 22, and an open (or otherwise insufficiently closed) position of the anvil 24 with respect to the channel 22. Other conditions to which the lockout sensor switches 136 a-d may respond, such as component wear, may be inferred based upon an accumulated number of firing operations produced by the instrument 10. Accordingly, if any of these conditions exists, the corresponding lockout sensor switches 136 a-d maintain an open switch state, thus preventing passage of the current necessary to initiate operation of the motor 65. Passage of current by the lockout sensors 136 a-d is allowed only after all of the conditions have been remedied. It will be appreciated that the above-described conditions are provided by way of example only, and that additional lockout sensor switches for responding to other conditions detrimental to operation of the instrument 10 may be provided. It will similarly be appreciated that for embodiments in which one or more of the above-described conditions may not exist or are of no concern, the number of lockout sensor switches may be fewer than that depicted.

    As shown in FIG. 11A, the lockout sensor switch 136 a may be implemented using a normally-open switch configuration such that a closed switch state is maintained when the staple cartridge 34 is in a position corresponding to its proper receipt by the channel 22. When the staple cartridge 34 is not installed in the channel 22, or is installed improperly (e.g., mis-aligned), the lockout sensor switch 136 a maintains an open switch state.
  • [0078]
    Lockout sensor switch 136 b may be implemented using a normally-open switch configuration such that a closed switch state is maintained only when an unspent staple cartridge 34 (i.e., a staple cartridge 34 having a sled 33 in the unfired position) is present in the channel 22. The presence of a spent staple cartridge 34 in the channel 22 causes the lockout sensor switch 136 b to maintain an open switch state.
  • [0079]
    Lockout sensor switch 136 c may be implemented using a normally-open switch configuration such that a closed switch state is maintained when the anvil 24 is in a closed position with respect to the channel 22. As discussed in further detail below, the lockout sensor switch 136 c may be controlled in accordance with a time delay feature wherein a closed switch state is maintained only after the anvil 24 is in the closed position for a pre-determined period of time.
  • [0080]
    Lockout sensor switch 136 d may be implemented using a normally-closed switch configuration such that a closed switch state is maintained only when an accumulated number of firings produced by the instrument 10 is less than a pre-determined number. As discussed in further detail below, the lockout sensor switch 136 d may be in communication with a counter 304 configured for maintaining a count representative of the accumulated number of firing operations performed by the instrument, comparing the count to the pre-determined number, and controlling the switch state of the lockout sensor switch 136 d based upon the comparison.
  • [0081]
    According to various embodiments, the interlock circuit 137 may comprise one or more indicators visible to the user of the instrument 10 for displaying a status of at least one of the lockout sensor switches 136 a-d. As shown in FIG. 11A, for example, each lockout sensor switch 136 a-d may have a green LED 139 a and a red LED 139 b associated therewith. The interlock circuit 137 may be configured such that the LEDs 139 a,b are energized when the corresponding lockout sensor switch 136 a-d is maintained in the closed and open switch states, respectively. It will be appreciated that the lockout sensor switches 136 a-d may comprise one or more auxiliary switch contacts (not shown) having a switch configuration suitable for operating the LEDs 139 a,b in the manner described above.
  • [0082]
    FIGS. 11B-11F illustrate mounting arrangements and configurations of the lockout sensor switches 136 a-d of the interlock circuit 137 according to various embodiments of the present invention. As shown in FIG. 11B, the lockout sensor switch 136 a may comprise a first switch contact 288 a and a second switch contact 288 b disposed upon an inner wall of the channel 22 and electrically isolated therefrom. The respective positions of the first and second switch contacts 288 a,b are such that when the staple cartridge 34 is in a position corresponding to its proper receipt by the channel 22, a conductive or semi-conductive portion 290 of the staple cartridge 34 (exemplified as a metal tray portion of the staple cartridge 34) contacts the first and second switch contacts 288 a,b to establish a conductive path therebetween. As best seen in FIG. 11C, each switch contact 288 a,b may comprise a rounded profile for minimizing mechanical resistance to the staple cartridge 34 when received by the channel 22 and for enabling affirmative electrical contact with the conductive portion 290 thereof. The conductive portion 290 thus operates to maintain the lockout sensor switch 136 a in a closed switch state. Although the switch contacts 288 a,b are shown adjacently positioned on a sidewall portion of the channel 22, it will be appreciated that each switch contact 288 a,b may generally be located at any location within the channel 22 where suitable electrical contact with the conductive member 290 is possible. It will further be appreciated that the lockout sensor switch 136 a may alternatively be implemented using a conventional contact-actuated limit switch. According to such embodiments, the limit switch may be positioned such that staple cartridge 34, when received by the channel 22, mechanically actuates the limit switch such that a closed switch state is maintained. It will further be appreciated that the lockout sensor switch 136 a may also be implemented using a conventional non-contact actuated limit switch, such as, for example, a magnetic reed limit switch or a Hall effect proximity switch. According to such embodiments, the staple cartridge 34 may comprise a magnet suitable for causing the lockout sensor switch 136 a to maintain a closed switch state when the staple cartridge 34 is installed.
  • [0083]
    As best seen in FIG. 11C, the lockout sensor switch 136 b may be mounted on an interior bottom surface of the channel 22. According to various embodiments and as shown, the lockout sensor switch 136 b may be implemented using a contact-actuated limit switch of a conventional design that is suitable for detecting linear movement. Orientation of the lockout sensor switch 136 b may be such that an actuated portion thereof extends upwardly from the bottom interior surface of the channel 22. The position of the lockout sensor switch 136 b on the bottom surface of the channel 22 is such that when an unspent staple cartridge 34 is installed, a bottom portion of the sled 33 mechanically actuates the lockout sensor switch 136 b and causes a closed switch state to be maintained thereby. Accordingly, the presence of an unspent staple cartridge 34 (i.e., a staple cartridge having a sled 33 in the unfired position) enables the passage of current through the lockout sensor switch 136 b. It will be appreciated the lockout sensor switch 136 b may instead be implemented using a non-contact actuated switch (e.g., a magnetic reed limit switch or a Hall effect proximity switch). For such implementations, the sled 33 may comprise a magnetized portion, for example, that actuates the lockout sensor switch 136 b when the sled 33 is present in the un-fired position.
  • [0084]
    As shown in FIG. 11D, the lockout sensor switch 136 c is positioned adjacent a distal end of one of the pivot recesses 296 defined by the proximal end of the channel 22 for engaging a corresponding pivot point 25 of the anvil 24. According to various embodiments and as shown, the lockout sensor switch 136 c may be implemented using a contact-actuated limit switch of a conventional design that is suitable for detecting linear movement. It will be appreciated, however, that a non-contact-actuated limit switch may be used instead. Orientation of the lockout sensor switch 136 c may be such that an actuated portion thereof extends slightly over the distal end of the corresponding pivot recess 296. When the anvil 24 is in an open position with respect to the channel 22 (as shown in FIG. 11D), the pivot point 25 is positioned at the proximal end of the pivot recess 296. Closure of the anvil 24 causes the pivot point 25 to move to the distal end of the pivot recess 296. The resulting contact of the pivot point 25 with the actuated portion of the lockout sensor switch 136 c causes the lockout sensor switch 136 c to maintain a closed switch state, thus enabling the passage of current therethrough.
  • [0085]
    According to other embodiments and as shown in FIG. 11E, the lockout sensor switch 136 c may instead be configured to maintain a closed switch state responsive to an electrical signal. The electrical signal may be, for example, an analog signal generated by a force sensor 298 disposed on a bottom inner surface of the channel 22 that represents a magnitude of the clamping force applied by the anvil 24. The closed position of the anvil 24 may thus be inferred if the analog signal is sufficiently large in magnitude. Accordingly, the analog signal may be received by a comparator circuit 141 configured to determine if the magnitude exceeds a pre-determined threshold stored therein. If the threshold is exceeded, indicating closure of the anvil 24, the comparator circuit 141 causes the lockout sensor switch 136 c to maintain a closed switch state, thus enabling the passage of current therethrough. If the magnitude of the analog signal is less than the pre-determined threshold, indicating that the anvil 24 is not sufficiently closed, the comparator circuit 141 causes the lockout sensor switch 136 c to maintain an open switch state, thus preventing the passage of current therethrough. Although shown separately, it will be appreciated that the comparator circuit 141 may be integral with the lockout sensor switch 136 c so as to form a common device. It will further be appreciated that the pre-defined threshold stored by the comparator circuit 141 may be adjusted as necessary to reflect the force indicative of closure of the anvil 24 for different cutting and stapling operations.
  • [0086]
    In certain instances, it may be necessary or otherwise desirable to delay commencement of a firing operation for a period of time subsequent to closure of the anvil 24. For example, the introduction of a delay between the clamping and firing operations may serve to improve the stabilization of clamped tissue. Accordingly, with reference to FIG. 11F, embodiments of the present invention may comprise a timer 300 having a pre-set time delay (e.g., 12 seconds) and configured for controlling the switch state of the lockout sensor switch 136 c in accordance with a time-based position of the anvil 24. Although shown separately, it will be appreciated that the timer 300 may be integral with the lockout sensor switch 136 c so as to form a common device (e.g., an on-delay timer). Preferably, the timer 300 is implemented as an electronic device, although it will be appreciated that a mechanical timer may be used instead. A normally-open limit switch 302 configured in a manner identical to that of FIG. 11D may be connected to the timer 300 such that timing is initiated when the anvil 24 is in a closed position with respect to the channel 22. Upon expiration of the pre-set time delay, the timer 300 causes the lockout sensor switch 136 c to maintain a closed switch state, thus enabling the passage of current therethrough. The timer 300 may be reset in response to the transition of the limit switch 302 to an open switch state (i.e., when the anvil 24 is in the open position). It will be appreciated that the pre-set time delay of the timer 300 may be selectively adjusted (e.g., using an integral potentiometer adjustment) as required.
  • [0087]
    Referring again to FIG. 11A, the electrical circuit may comprise a counter 304 configured to maintain a count representative of the accumulated number of firing operations performed by the instrument 10 and, based on the count, to control the switch state of the lockout sensor switch 136 d. Although shown separately, it will be appreciated that counter 304 may be integral with the lockout sensor switch 136 d so as to form a common device. Preferably, the counter 304 is implemented as an electronic device having an input for incrementing the maintained count based upon the transition of a discrete electrical signal provided thereto. It will be appreciated that a mechanical counter configured for maintaining the count based upon a mechanical input (e.g., retraction of the firing trigger 20) may be used instead. When implemented as an electronic device, any discrete signal present in the electrical circuit that transitions once for each firing operation may be utilized for the counter 304 input. As shown in FIG. 11A, for example, the discrete electrical signal resulting from actuation of the end-of-stroke sensor 130 may be utilized. The counter 304 may control the switch state of lockout sensor switch 136 d such that a closed switch state is maintained when the maintained count is less than a pre-determined number stored within the counter 304. When the maintained count is equal to the pre-determined number, the counter 304 causes the lockout sensor switch 136 d to maintain an open switch state, thus preventing the passage of current therethrough. It will be appreciated that the pre-determined number stored by the counter 304 may be selectively adjusted as required. According to various embodiments, the counter 304 may be in communication with a display 305, such as an LCD display, integral to the instrument 10 for indicating to a user either the maintained count or the difference between the pre-determined number and the maintained count.
  • [0088]
    When the lockout sensor switches 136 a-d collectively maintain a closed switch state, a single pole, single throw relay 138 is energized. When the relay 138 is energized, current flows through the relay 138, through the variable resistor sensor 110, and to the motor 65 via a double pole, double throw relay 140, thereby powering the motor 65 and allowing it to rotate in the forward direction. Because the output of the relay 138, once energized, maintains the relay 138 in an energized state until relay 132 is energized, the interlock circuit 137 will not function to prevent operation of the motor 165 once initiated, even if one or more of the interlock sensor switches 136 a-d subsequently maintains an open switch state. In other embodiments, however, it may be necessary or otherwise desirable to connect the interlock circuit 137 and the relay 138 such that one or more the lockout sensor switches 136 a-d must maintain a closed switch state in order to sustain operation of the motor 165 once initiated.
  • [0089]
    Rotation of the motor in the forward direction causes the ring 84 to move distally and thereby de-actuate the stop motor sensor switch 142. Because the switch 142 is normally-closed, solenoid 306 is energized. The solenoid 306 may be a conventional push-type solenoid that, when energized, causes a plunger (not shown) to be axially extended. As discussed below in connection with FIGS. 14-22, extension of the plunger may operate to retain the closure trigger 18 in the retracted position, thus preventing the anvil 24 from opening while a firing operation is in progress (i.e., while the switch 142 is not actuated). Upon de-energization of the solenoid 306, the plunger is retracted such that manual release of the closure trigger 18 is possible.
  • [0090]
    When the end effector 12 reaches the end of its stroke, the reverse motor sensor 130 will be activated, thereby closing the switch 130 and energizing the relay 132. This causes the relay 132 to assume its energized state (not shown in FIG. 11A), which causes current to bypass interlock circuit 137 and variable resistor 110, and instead causes current to flow to both the normally-closed double pole, double throw relay 140 and back to the motor 65, but in a manner, via the relay 140, that causes the motor 65 to reverse its rotational direction.
  • [0091]
    Because the stop motor sensor switch 142 is normally-closed, current will flow back to the relay 132 to keep it energized until the switch 142 opens. When the knife 32 is fully retracted, the stop motor sensor switch 142 is activated, causing the switch 142 to open, thereby removing power from the motor 65 and de-energizing the solenoid 306.
  • [0092]
    In other embodiments, rather than a proportional-type sensor 110, an on-off type sensor could be used. In such embodiments, the rate of rotation of the motor 65 would not be proportional to the force applied by the operator. Rather, the motor 65 would generally rotate at a constant rate. But the operator would still experience force feedback because the firing trigger 20 is geared into the gear drive train.
  • [0093]
    FIG. 12 is a side-view of the handle 6 of a power-assist motorized endocutter according to another embodiment. The embodiment of FIG. 12 is similar to that of FIGS. 7-10 except that in the embodiment of FIG. 12, there is no slotted arm connected to the ring 84 threaded on the helical gear drum 80. Instead, in the embodiment of FIG. 12, the ring 84 includes a sensor portion 114 that moves with the ring 84 as the ring 84 advances down (and back) on the helical gear drum 80. The sensor portion 114 includes a notch 116. The reverse motor sensor 130 may be located at the distal end of the notch 116 and the stop motor sensor 142 may be located at the proximate end of the notch 116. As the ring 84 moves down the helical gear drum 80 (and back), the sensor portion 114 moves with it. Further, as shown in FIG. 12, the middle piece 104 may have an arm 118 that extends into the notch 116.
  • [0094]
    In operation, as an operator of the instrument 10 retracts in the firing trigger 20 toward the pistol grip 26, the run motor sensor 110 detects the motion and sends a signal to power the motor 65, which causes, among other things, the helical gear drum 80 to rotate. As the helical gear drum 80 rotates, the ring 84 threaded on the helical gear drum 80 advances (or retracts, depending on the rotation). Also, due to the pulling in of the firing trigger 20, the middle piece 104 is caused to rotate counter clockwise with the firing trigger 20 due to the forward motion stop 107 that engages the firing trigger 20. The counter clockwise rotation of the middle piece 104 cause the arm 118 to rotate counter clockwise with the sensor portion 114 of the ring 84 such that the arm 118 stays disposed in the notch 116. When the ring 84 reaches the distal end of the helical gear drum 80, the arm 118 will contact and thereby trip the reverse motor sensor 130. Similarly, when the ring 84 reaches the proximate end of the helical gear drum 80, the arm 118 will contact and thereby trip the stop motor sensor 142. Such actions may reverse and stop the motor 65, respectively as described above.
  • [0095]
    FIG. 13 is a side-view of the handle 6 of a power-assist motorized endocutter according to another embodiment. The embodiment of FIG. 13 is similar to that of FIGS. 7-10 except that in the embodiment of FIG. 13, there is no slot in the arm 90. Instead, the ring 84 threaded on the helical gear drum 80 includes a vertical channel 126. Instead of a slot, the arm 90 includes a post 128 that is disposed in the channel 126. As the helical gear drum 80 rotates, the ring 84 threaded on the helical gear drum 80 advances (or retracts, depending on the rotation). The arm 90 rotates counter clockwise as the ring 84 advances due to the post 128 being disposed in the channel 126, as shown in FIG. 13.
  • [0096]
    As mentioned above, in using a two-stroke motorized instrument, the operator first pulls back and locks the closure trigger 18. FIGS. 14 and 15 show one embodiment of a way to lock the closure trigger 18 to the pistol grip portion 26 of the handle 6. In the illustrated embodiment, the pistol grip portion 26 includes a hook 150 that is biased to rotate counter clockwise about a pivot point 151 by a torsion spring 152. Also, the closure trigger 18 includes a closure bar 154. As the operator draws in the closure trigger 18, the closure bar 154 engages a sloped portion 156 of the hook 150, thereby rotating the hook 150 upward (or clockwise in FIGS. 14-15) until the closure bar 154 completely passes the sloped portion 156 into a recessed notch 158 of the hook 150, which locks the closure trigger 18 in place. The operator may release the closure trigger 18 by pushing down on a slide button release 160 on the back or opposite side of the pistol grip portion 26. Pushing down the slide button release 160 rotates the hook 150 clockwise such that the closure bar 154 is released from the recessed notch 158. In order to prevent the anvil 24 from inadvertently being opened while a firing operation is in progress, the solenoid 306 may be positioned within the pistol grip 26 such that the plunger 308 of the solenoid 306, when energized, is received into a corresponding opening 163 of the slide button release 160. Accordingly, the slide button release 160 is locked in place such that manipulation of the slide button release 160 is prevented until the plunger 308 is retracted from the opening 163 at the conclusion of the firing operation.

    FIG. 16 shows another closure trigger locking mechanism according to various embodiments. In the embodiment of FIG. 16, the closure trigger 18 includes a wedge 160 having an arrow-head portion 161. The arrow-head portion 161 is biased downward (or clockwise) by a leaf spring 162. The wedge 160 and leaf spring 162 may be made from, for example, molded plastic. When the closure trigger 18 is retracted, the arrow-head portion 161 is inserted through an opening 164 in the pistol grip portion 26 of the handle 6. A lower chamfered surface 166 of the arrow-head portion 161 engages a lower sidewall 168 of the opening 164, forcing the arrow-head portion 161 to rotate counter clockwise. Eventually the lower chamfered surface 166 fully passes the lower sidewall 168, removing the counter clockwise force on the arrow-head portion 161, causing the lower sidewall 168 to slip into a locked position in a notch 170 behind the arrow-head portion 161.
  • [0098]
    To unlock the closure trigger 18, a user presses down on a button 172 on the opposite side of the closure trigger 18, causing the arrow-head portion 161 to rotate counter clockwise and allowing the arrow-head portion 161 to slide out of the opening 164. In order to prevent the anvil 24 from inadvertently being opened while a firing operation is in progress, the solenoid 306 may be positioned within the pistol grip 26 such that the plunger 308 of the solenoid 306, when energized, is received into a corresponding opening 173 defined by the arrow-head portion 161. When received into the opening 173, the plunger 308 operates to prevent CCW rotation of the arrow-head portion 161. Accordingly, inadvertent manipulation of the button 172 by the user is prevented by the user until the plunger 308 is retracted from the opening 173 at the conclusion of the firing operation.
  • [0099]
    FIGS. 17-22 show a closure trigger locking mechanism according to another embodiment. As shown in this embodiment, the closure trigger 18 includes a flexible longitudinal arm 176 that includes a lateral pin 178 extending therefrom. The arm 176 and pin 178 may be made from molded plastic, for example. The pistol grip portion 26 of the handle 6 includes an opening 180 with a laterally extending wedge 182 disposed therein. When the closure trigger 18 is retracted, the pin 178 engages the wedge 182, and the pin 178 is forced downward (i.e., the arm 176 is rotated clockwise) by the lower surface 184 of the wedge 182, as shown in FIGS. 17 and 18. When the pin 178 fully passes the lower surface 184, the clockwise force on the arm 176 is removed, and the pin 178 is rotated counter clockwise such that the pin 178 comes to rest in a notch 186 behind the wedge 182, as shown in FIG. 19, thereby locking the closure trigger 18. The pin 178 is further held in place in the locked position by a flexible stop 188 extending from the wedge 184.
  • [0100]
    To unlock the closure trigger 18, the operator may further squeeze the closure trigger 18, causing the pin 178 to engage a sloped backwall 190 of the opening 180, forcing the pin 178 upward past the flexible stop 188, as shown in FIGS. 20 and 21. The pin 178 is then free to travel out an upper channel 192 in the opening 180 such that the closure trigger 18 is no longer locked to the pistol grip portion 26, as shown in FIG. 22. In order to prevent the anvil 24 from inadvertently being opened while a firing operation is in progress, the solenoid 306 may be positioned within the pistol grip 26 such that the plunger 308 of the solenoid 306, when energized, is received into the upper channel 192. When received into the upper channel 192, the plunger 308 operates to prevent passage of the pin 178 therethrough. Accordingly, unlocking the closure trigger 18 is prevented until the plunger 308 is retracted from the upper channel 192 at the conclusion of the firing operation.

Also, the user may provide power to the system via the gear box assembly 200 to assist the deployment of the end effector 12. In that sense, like the embodiments described above, the embodiment of FIGS. 25-31 is another power assist motorized instrument 10 that provides feedback to the user regarding the loading force experienced by the instrument.

    In the illustrated embodiment, the firing trigger 20 includes two pieces: a main body portion 202 and a stiffening portion 204.

    In operation, when the user retracts the firing trigger 20, a run motor sensor (not shown) is activated, which may provide a signal to the motor 65 to rotate at a rate proportional to the extent or force with which the operator is retracting the firing trigger 20. This causes the motor 65 to rotate at a speed proportional to the signal from the sensor. The sensor is not shown for this embodiment, but it could be similar to the run motor sensor 110 described above. The sensor could be located in the handle 6 such that it is depressed when the firing trigger 20 is retracted. Also, instead of a proportional-type sensor, an on/off type sensor may be used.
  • [0107]
    Rotation of the motor 65 causes the bevel gears 66, 70 to rotate, which causes the planetary gear 72 to rotate, which causes, via the drive shaft 76, the ring gear 122 to rotate. The ring gear 122 meshes with the pinion gear 124, which is connected to the main drive shaft 48. Thus, rotation of the pinion gear 124 drives the main drive shaft 48, which causes actuation of the cutting/stapling operation of the end effector 12.
  • [0108]
    Forward rotation of the pinion gear 124 in turn causes the bevel gear 220 to rotate, which causes, by way of the rest of the gears of the gear box assembly 200, the first gear 210 to rotate. The first gear 210 engages the gear portions 206, 208 of the firing trigger 20, thereby causing the firing trigger 20 to rotate counter clockwise when the motor 65 provides forward drive for the end effector 12 (and to rotate counter clockwise when the motor 65 rotates in reverse to retract the end effector 12). In that way, the user experiences feedback regarding loading force and deployment of the end effector 12 by way of the user's grip on the firing trigger 20. Thus, when the user retracts the firing trigger 20, the operator will experience a resistance related to the load force experienced by the end effector 12. Similarly, when the operator releases the firing trigger 20 after the cutting/stapling operation so that it can return to its original position, the user will experience a clockwise rotation force from the firing trigger 20 that is generally proportional to the reverse speed of the motor 65.
  • [0109]
    It should also be noted that in this embodiment the user can apply force (either in lieu of or in addition to the force from the motor 65) to actuate the main drive shaft assembly (and hence the cutting/stapling operation of the end effector 12) through retracting the firing trigger 20. That is, retracting the firing trigger 20 causes the gear portions 206, 208 to rotate counter clockwise, which causes the gears of the gear box assembly 200 to rotate, thereby causing the pinion gear 124 to rotate, which causes the main drive shaft 48 to rotate.
  • [0110]
    Although not shown in FIGS. 25-31, the instrument 10 may further include reverse motor and stop motor sensors. As described above, the reverse motor and stop motor sensors may detect, respectively, the end of the cutting stroke (full deployment of the knife 32 and sled 33) and the end of retraction operation (full retraction of the knife 32). A circuit similar to that described above in connection with FIG. 11 or FIG. 11A may be used to appropriately power the motor 65.
  • [0111]
    FIGS. 32-36 illustrate a two-stroke, motorized surgical cutting and fastening instrument 10 with power assist according to another embodiment. The embodiment of FIGS. 32-36 is similar to that of FIGS. 25-31 except that in the embodiment of FIGS. 32-36, the firing trigger 20 includes a lower portion 228 and an upper portion 230. Both portions 228, 230 are connected to and pivot about a pivot pin 207 that is disposed through each portion 228, 230. The upper portion 230 includes a gear portion 232 that engages the first gear 210 of the gear box assembly 200. The spring 222 is connected to the upper portion 230 such that the upper portion is biased to rotate in the clockwise direction. The upper portion 230 may also include a lower arm 234 that contacts an upper surface of the lower portion 228 of the firing trigger 20 such that when the upper portion 230 is caused to rotate clockwise the lower portion 228 also rotates clockwise, and when the lower portion 228 rotates counter clockwise the upper portion 230 also rotates counter clockwise. Similarly, the lower portion 228 includes a rotational stop 238 that engages a shoulder of the upper portion 230. In that way, when the upper portion 230 is caused to rotate counter clockwise the lower portion 228 also rotates counter clockwise, and when the lower portion 228 rotates clockwise the upper portion 230 also rotates clockwise.
  • [0112]
    The illustrated embodiment also includes the run motor sensor 110 that communicates a signal to the motor 65 that, in various embodiments, may cause the motor 65 to rotate at a speed proportional to the force applied by the operator when retracting the firing trigger 20. The sensor 110 may be, for example, a rheostat or some other variable resistance sensor, as explained herein. In addition, the instrument 10 may include a reverse motor sensor 130 that is tripped or switched when contacted by a front face 242 of the upper portion 230 of the firing trigger 20. When activated, the reverse motor sensor 130 sends a signal to the motor 65 to reverse direction. Also, the instrument 10 may include a stop motor sensor 142 that is tripped or actuated when contacted by the lower portion 228 of the firing trigger 20. When activated, the stop motor sensor 142 sends a signal to stop the reverse rotation of the motor 65.
  • [0113]
    In operation, when an operator retracts the closure trigger 18 into the locked position, the firing trigger 20 is retracted slightly (through mechanisms known in the art, including U.S. Pat. No. 6,978,921 and U.S. Pat. No. 6,905,057, which are incorporated herein by reference) so that the user can grasp the firing trigger 20 to initiate the cutting/stapling operation, as shown in FIGS. 32 and 33. At that point, as shown in FIG. 33, the gear portion 232 of the upper portion 230 of the firing trigger 20 moves into engagement with the first gear 210 of the gear box assembly 200. When the operator retracts the firing trigger 20, according to various embodiments, the firing trigger 20 may rotate a small amount, such as five degrees, before tripping the run motor sensor 110, as shown in FIG. 34. Activation of the sensor 110 causes the motor 65 to forward rotate at a rate proportional to the retraction force applied by the operator. The forward rotation of the motor 65 causes, as described above, the main drive shaft 48 to rotate, which causes the knife 32 in the end effector 12 to be deployed (i.e., begin traversing the channel 22). Rotation of the pinion gear 124, which is connected to the main drive shaft 48, causes the gears 210-220 in the gear box assembly 200 to rotate. Since the first gear 210 is in engagement with the gear portion 232 of the upper portion 230 of the firing trigger 20, the upper portion 230 is caused to rotate counter clockwise, which causes the lower portion 228 to also rotate counter clockwise.
  • [0114]
    When the knife 32 is fully deployed (i.e., at the end of the cutting stroke), the front face 242 of the upper portion 230 trips the reverse motor sensor 130, which sends a signal to the motor 65 to reverse rotational direction. This causes the main drive shaft assembly to reverse rotational direction to retract the knife 32. Reverse rotation of the main drive shaft assembly also causes the gears 210-220 in the gear box assembly 200 to reverse direction, which causes the upper portion 230 of the firing trigger 20 to rotate clockwise, which causes the lower portion 228 of the firing trigger 20 to rotate clockwise until the front face 242 of the upper portion 228 trips or actuates the stop motor sensor 142 when the knife 32 is fully retracted, which causes the motor 65 to stop. In that way, the user experiences feedback regarding deployment of the end effector 12 by way of the user's grip on the firing trigger 20. Thus, when the user retracts the firing trigger 20, the operator will experience a resistance related to the deployment of the end effector 12 and, in particular, to the loading force experienced by the knife 32. Similarly, when the operator releases the firing trigger 20 after the cutting/stapling operation so that it can return to its original position, the user will experience a clockwise rotation force from the firing trigger 20 that is generally proportional to the reverse speed of the motor 65.
  • [0115]
    It should also be noted that in this embodiment the user can apply force (either in lieu of or in addition to the force from the motor 65) to actuate the main drive shaft assembly (and hence the cutting/stapling operation of the end effector 12) through retracting the firing trigger 20. That is, retracting the firing trigger 20 causes the gear portion 232 of the upper portion 230 to rotate counter clockwise, which causes the gears of the gear box assembly 200 to rotate, thereby causing the pinion gear 124 to rotate, which causes the main drive shaft assembly to rotate.
  • [0116]
    The above-described embodiments employed power-assist user feedback systems, with or without adaptive control (e.g., using a sensor 110, 130, and 142 outside of the closed loop system of the motor 65, gear drive train, and end effector 12) for a two-stroke, motorized surgical cutting and fastening instrument. That is, force applied by the user in retracting the firing trigger 20 may be added to the force applied by the motor 65 by virtue of the firing trigger 20 being geared into (either directly or indirectly) the gear drive train between the motor 65 and the main drive shaft 48. In other embodiments of the present invention, the user may be provided with tactile feedback regarding the position of the knife 32 in the end effector, but without having the firing trigger 20 geared into the gear drive train. FIGS. 37-40 illustrate a motorized surgical cutting and fastening instrument with such a tactile position feedback system.
  • [0117]
    In the illustrated embodiment of FIGS. 37-40, the firing trigger 20 may have a lower portion 228 and an upper portion 230, similar to the instrument 10 shown in FIGS. 32-36. Unlike the embodiment of FIG. 32-36, however, the upper portion 230 does not have a gear portion that mates with part of the gear drive train. Instead, the instrument includes a second motor 265 with a threaded rod 266 threaded therein. The threaded rod 266 reciprocates longitudinally in and out of the motor 265 as the motor 265 rotates, depending on the direction of rotation. The instrument 10 also includes an encoder 268 that is responsive to the rotations of the main drive shaft 48 for translating the incremental angular motion of the main drive shaft 48 (or other component of the main drive assembly) into a corresponding series of digital signals, for example. In the illustrated embodiment, the pinion gear 124 includes a proximate drive shaft 270 that connects to the encoder 268.
  • [0118]
    The instrument 10 also includes a control circuit (not shown), which may be implemented using a microcontroller or some other type of integrated circuit, that receives the digital signals from the encoder 268. Based on the signals from the encoder 268, the control circuit may calculate the stage of deployment of the knife 32 in the end effector 12. That is, the control circuit can calculate if the knife 32 is fully deployed, fully retracted, or at an intermittent stage. Based on the calculation of the stage of deployment of the end effector 12, the control circuit may send a signal to the second motor 265 to control its rotation to thereby control the reciprocating movement of the threaded rod 266.
  • [0119]
    In operation, as shown in FIG. 37, when the closure trigger 18 is not locked into the clamped position, the firing trigger 20 rotated away from the pistol grip portion 26 of the handle 6 such that the front face 242 of the upper portion 230 of the firing trigger 20 is not in contact with the proximate end of the threaded rod 266. When the operator retracts the closure trigger 18 and locks it in the clamped position, the firing trigger 20 rotates slightly towards the closure trigger 18 so that the operator can grasp the firing trigger 20, as shown in FIG. 38. In this position, the front face 242 of the upper portion 230 contacts the proximate end of the threaded rod 266.
  • [0120]
    As the user then retracts the firing trigger 20, after an initial rotational amount (e.g. 5 degrees of rotation) the run motor sensor 110 may be activated such that, as explained above, the sensor 110 sends a signal to the motor 65 to cause it to rotate at a forward speed proportional to the amount of retraction force applied by the operator to the firing trigger 20. Forward rotation of the motor 65 causes the main drive shaft 48 to rotate via the gear drive train, which causes the knife 32 and sled 33 to travel down the channel 22 and sever tissue clamped in the end effector 12. The control circuit receives the output signals from the encoder 268 regarding the incremental rotations of the main drive shaft assembly and sends a signal to the second motor 265 to cause the second motor 265 to rotate, which causes the threaded rod 266 to retract into the motor 265. This allows the upper portion 230 of the firing trigger 20 to rotate counter clockwise, which allows the lower portion 228 of the firing trigger to also rotate counter clockwise. In that way, because the reciprocating movement of the threaded rod 266 is related to the rotations of the main drive shaft assembly, the operator of the instrument 10, by way of his/her grip on the firing trigger 20, experiences tactile feedback as to the position of the end effector 12. The retraction force applied by the operator, however, does not directly affect the drive of the main drive shaft assembly because the firing trigger 20 is not geared into the gear drive train in this embodiment.
  • [0121]
    By virtue of tracking the incremental rotations of the main drive shaft assembly via the output signals from the encoder 268, the control circuit can calculate when the knife 32 is fully deployed (i.e., fully extended). At this point, the control circuit may send a signal to the motor 65 to reverse direction to cause retraction of the knife 32. The reverse direction of the motor 65 causes the rotation of the main drive shaft assembly to reverse direction, which is also detected by the encoder 268. Based on the reverse rotation detected by the encoder 268, the control circuit sends a signal to the second motor 265 to cause it to reverse rotational direction such that the threaded rod 266 starts to extend longitudinally from the motor 265. This motion forces the upper portion 230 of the firing trigger 20 to rotate clockwise, which causes the lower portion 228 to rotate clockwise. In that way, the operator may experience a clockwise force from the firing trigger 20, which provides feedback to the operator as to the retraction position of the knife 32 in the end effector 12. The control circuit can determine when the knife 32 is fully retracted. At this point, the control circuit may send a signal to the motor 65 to stop rotation.
  • [0122]
    According to other embodiments, rather than having the control circuit determine the position of the knife 32, reverse motor and stop motor sensors may be used, as described above. In addition, rather than using a proportional sensor 110 to control the rotation of the motor 65, an on/off switch or sensor can be used. In such an embodiment, the operator would not be able to control the rate of rotation of the motor 65. Rather, it would rotate at a preprogrammed rate.
  • [0123]
    FIGS. 41-43 illustrate an exemplary embodiment of a mechanically actuated endocutter, and in particular the handle 6, shaft 8 and end effector 12 thereof. Further details of a mechanically actuated endocutter may be found in U.S. patent application Ser. No. 11/052,632 entitled, MULTI-STROKE MECHANISM WITH AUTOMATIC END OF STROKE RETRACTION, now U.S. Pat. No. 7,083,075, which is incorporated herein by reference. With reference to FIG. 41, the end effector 12 responds to the closure motion from the handle 6 (not depicted in FIG. 41) first by including an anvil face 1002 connecting to an anvil proximal end 1004 that includes laterally projecting anvil pivot pins 25 that are proximal to a vertically projecting anvil tab 27. The anvil pivot pins 25 translate within kidney shaped openings 1006 in the staple channel 22 to open and close anvil 24 relative to channel 22. The tab 27 engages a bent tab 1007 extending inwardly in tab opening 45 on a distal end 1008 of the closure tube 1005, the latter distally terminating in a distal edge 1008 that pushes against the anvil face 1002. Thus, when the closure tube 1005 moves proximally from its open position, the bent tab 1007 of the closure tube 1005 draws the anvil tab 27 proximally, and the anvil pivot pins 25 follow the kidney shaped openings 1006 of the staple channel 22 causing the anvil 24 to simultaneously translate proximally and rotate upward to the open position. When the closure tube 1005 moves distally, the bent tab 1007 in the tab opening 45 releases from the anvil tab 27 and the distal edge 1008 pushes on the anvil face 1002, closing the anvil 24.
  • [0124]
    With continued reference to FIG. 41, the shaft 8 and end effector 12 also include components that respond to a firing motion of a firing rod 1010. In particular, the firing rod 1010 rotatably engages a firing trough member 1012 having a longitudinal recess 1014. Firing trough member 1012 moves longitudinally within frame 1016 in direct response to longitudinal motion of firing rod 1010. A longitudinal slot 1018 in the closure tube 1005 operably couples with the right and left exterior side handle pieces 61, 62 of the handle 6 (not shown in FIG. 41). The length of the longitudinal slot 1018 in the closure tube 1005 is sufficiently long to allow relative longitudinal motion with the handle pieces 61, 62 to accomplish firing and closure motions respectively with the coupling of the handle pieces 61, 62 passing on through a longitudinal slot 1020 in the frame 1016 to slidingly engage the longitudinal recess 1014 in the frame trough member 1012.
  • [0125]
    The distal end of the frame trough member 1012 is attached to a proximal end of a firing bar 1022 that moves within the frame 1016, specifically within a guide 1024 therein, to distally project the knife 32 into the end effector 12. The end effector 12 includes a staple cartridge 34 that is actuated by the knife 32. The staple cartridge 34 has a tray 1028 that holds a staple cartridge body 1030, a wedge sled driver 33, staple drivers 1034 and staples 1036. It will be appreciated that the wedge sled driver 33 longitudinally moves within a firing recess (not shown) located between the cartridge tray 1028 and the cartridge body 1030. The wedge sled driver 33 presents camming surfaces that contact and lift the staple drivers 1034 upward, driving the staples 1036. The staple cartridge body 1030 further includes a proximally open, vertical slot 1031 for passage of the knife 32. Specifically, a cutting surface 1027 is provided along a distal end of knife 32 to cut tissue after it is stapled.
  • [0126]
    It should be appreciated that the shaft 8 is shown in FIG. 4 as a non-articulating shaft. Nonetheless, applications of the present invention may include instruments capable of articulation, for example, as such shown above with reference to FIGS. 1-4 and described in the following U.S. patents and patent applications, the disclosure of each being hereby incorporated by reference in their entirety: (1) SURGICAL INSTRUMENT INCORPORATING AN ARTICULATION MECHANISM HAVING ROTATION ABOUT THE LONGITUDINAL AXIS, U.S. Patent Application Publication No. 2005/0006434, filed Jul. 9, 2003, now U.S. Pat.

  • [0127]
    FIGS. 42-43 show an embodiment of the handle 6 that is configured for use in a mechanically actuated endocutter along with the embodiment of the shaft 8 and end effector 12 as shown above in FIG. 41. It will be appreciated that any suitable handle design may be used to mechanically close and fire the end effector 12. In FIGS. 42-43, the handle 6 of the surgical stapling and severing instrument 10 includes a linked transmission firing mechanism 1060 that provides features such as increased strength, reduced handle size, minimized binding, etc.
  • [0128]
    Closure of the end effector 12 (not shown in FIGS. 42-43) is caused by depressing the closure trigger 18 toward the pistol grip 26 of handle 6. The closure trigger 18 pivots about a closure pivot pin 252 that is coupled to right and left exterior lower side pieces 59, 60 the handle 6, causing an upper portion 1094 of the closure trigger 18 to move forward. The closure tube 1005 receives this closure movement via the closure yoke 250 that is pinned to a closure link 1042 and to the upper portion 1094 of the closure trigger 18 respectively by a closure yoke pin 1044 and a closure link pin 1046.
  • [0129]
    In the fully open position of FIG. 42, the upper portion 1094 of the closure trigger 18 contacts and holds a locking arm 1048 of the pivoting closure release button 30 in the position shown. When the closure trigger 18 reaches its fully depressed position, the closure trigger 18 releases the locking arm 1048 and an abutting surface 1050 rotates into engagement with a distal rightward notch 1052 of the pivoting locking arm 1048, holding the closure trigger 18 in this clamped or closed position. A proximal end of the locking arm 1048 pivots about a lateral pivotal connection 1054 with the pieces 59, 60 to expose the closure release button 30. An intermediate, distal side 1056 of the closure release button 30 is urged proximally by a compression spring 1058, which is compressed between a housing structure 1040 and closure release button 30. The result is that the closure release button 30 urges the locking arm 1048 counterclockwise (when viewed from the left) into locking contact with the abutting surface 1050 of closure trigger 18, which prevents unclamping of closure trigger 18 when the linked transmission firing system 1040 is in an un-retracted condition.
  • [0130]
    With the closure trigger 18 retracted and fully depressed, the firing trigger 20 is unlocked and may be depressed toward the pistol grip 26, multiple times in this embodiment, to effect firing of the end effector 12. As depicted, the linked transmission firing mechanism 1060 is initially retracted, urged to remain in this position by a combination tension/compression spring 1062 that is constrained within the pistol grip 26 of the handle 6, with its nonmoving end 1063 connected to the pieces 59, 60 and a moving end 1064 connected to a downwardly flexed and proximal, retracted end 1067 of a steel band 1066.
  • [0131]
    A distally-disposed end 1068 of the steel band 1066 is attached to a link coupling 1070 for structural loading, which in turn is attached to a front link 1072 a of a plurality of links 1072 a-1072 d that form a linked rack 1074. Linked rack 1074 is flexible yet has distal links that form a straight rigid rack assembly that may transfer a significant firing force through the firing rod 1010 in the shaft 6, yet readily retract into the pistol grip 26 to minimize the longitudinal length of the handle 6. It should be appreciated that the combination tension/compression spring 1062 increases the amount of firing travel available while essentially reducing the minimum length by half over a single spring.
  • [0132]
    The firing trigger 20 pivots about a firing trigger pin 96 that is connected to the handle pieces 59, 60. An upper portion 228 of the firing trigger 20 moves distally about the firing trigger pin 96 as the firing trigger 20 is depressed towards pistol grip 26, stretching a proximally placed firing trigger tension spring 222 proximally connected between the upper portion 228 of the firing trigger 20 and the pieces 59, 60. The upper portion 228 of the firing trigger 20 engages the linked rack 1074 during each firing trigger depression by a traction biasing mechanism 1078 that also disengages when the firing trigger 20 is released. Firing trigger tension spring 222 urges the firing trigger 20 distally when released and disengages the traction biasing mechanism 1078.
  • [0133]
    As the linked transmission firing mechanism 1040 actuates, an idler gear 1080 is rotated clockwise (as viewed from the left side) by engagement with a toothed upper surface 1082 of the linked rack 1074. This rotation is coupled to an indicator gear 1084, which thus rotates counterclockwise in response to the idler gear 1080. Both the idler gear 1080 and indicator gear 1084 are rotatably connected to the pieces 59, 60 of the handle 6. The gear relationship between the linked rack 1074, idler gear 1080 and indicator gear 1084 may be advantageously selected so that the toothed upper surface 1082 has tooth dimensions that are suitably strong and that the indicator gear 1084 makes no more than one revolution during the full firing travel of the linked transmission firing mechanism 1060.
  • [0134]
    As described in greater detail below, the indicator gear 1084 performs at least four functions. First, when the linked rack 1074 is fully retracted and both triggers 18, 20 are open as shown in FIG. 42, an opening 1086 in a circular ridge 1088 on the left side of the indicator gear 1084 is presented to an upper surface 1090 of the locking arm 1048. Locking arm 1048 is biased into the opening 1086 by contact with the closure trigger 18, which in turn is urged to the open position by a closure tension spring 1092. Closure trigger tension spring 1092 is connected proximally to the upper portion 1094 of the closure trigger 18 and the handle pieces 59, 60, and thus has energy stored during closing of the closure trigger 18 that urges the closure trigger 18 distally to its unclosed position.
  • [0135]
    A second function of the indicator gear 1084 is that it is connected to the indicating retraction knob 1096 externally disposed on the handle 6. Thus, the indicator gear 1084 communicates the relative position of the firing mechanism 1060 to the indicating retraction knob 1096 so that the surgeon has a visual indication of how many strokes of the firing trigger 20 are required to complete firing.
  • [0136]
    A third function of the indicator gear 1084 is to longitudinally and angularly move an anti-backup release lever 1098 of an anti-backup mechanism (one-way clutch mechanism) 1097 as the surgical stapling and severing instrument 10 is operated. During the firing strokes, proximal movement of anti-backup release lever 1098 by indicator gear 1084 activates the anti-backup mechanism 1097 that allows distal movement of firing bar 1010 and prevents proximal motion of firing bar 1010. This movement also extends the anti-backup release button 1100 from the proximal end of the handle pieces 59, 60 for the operator to actuate should the need arise for the linked transmission firing mechanism 1060 to be retracted during the firing strokes. After completion of the firing strokes, the indicator gear 1084 reverses direction of rotation as the firing mechanism 1060 retracts. The reversed rotation deactivates the anti-backup mechanism 1097, withdraws the anti-backup release button 1100 into the handle 6, and rotates the anti-backup release lever 1098 laterally to the right to allow continued reverse rotation of the indicator gear 1084.
  • [0137]
    A fourth function of the indicator gear 1084 is to receive a manual rotation from the indicating retraction knob 1096 (clockwise in the depiction of FIG. 42) to retract the firing mechanism 1060 with anti-backup mechanism 1097 unlocked, thereby overcoming any binding in the firing mechanism 1060 that is not readily overcome by the combination tension/compression spring 1062. This manual retraction assistance may be employed after a partial firing of the firing mechanism 1060 that would otherwise be prevented by the anti-backup mechanism 1097 that withdraws the anti-backup release button 1100 so that the latter may not laterally move the anti-backup release lever 1098.

    Continuing with FIGS. 42-43, anti-backup mechanism 1097 consists of the operator accessible anti-backup release lever 1098 operably coupled at the proximal end to the anti-backup release button 1100 and at the distal end to an anti-backup yoke 1102. In particular, a distal end 1099 of the anti-backup release lever 1098 is engaged to the anti-backup yoke 1102 by an anti-backup yoke pin 1104. The anti-backup yoke 1102 moves longitudinally to impart a rotation to an anti-backup cam slot tube 1106 that is longitudinally constrained by the handle pieces 59, 90 and that encompasses the firing rod 1010 distally to the connection of the firing rod 1010 to the link coupling 1070 of the linked rack 1074. The anti-backup yoke 1102 communicates the longitudinal movement from the anti-backup release lever 1098 via a cam slot tube pin 1108 to the anti-backup cam slot tube 1106. That is, longitudinal movement of cam slot tube pin 1108 in an angled slot in the anti-backup cam slot tube 1106 rotates the anti-backup cam slot tube 1106.
  • [0139]
    Trapped between a proximal end of the frame 1016 and the anti-backup cam slot tube 1106 respectively are an anti-backup compression spring 1110, an anti-backup plate 1112, and an anti-backup cam tube 1114. As depicted, proximal movement of the firing rod 1010 causes the anti-backup plate 1112 to pivot top to the rear, presenting an increased frictional contact to the firing rod 1010 that resists further proximal movement of the firing rod 1010.
  • [0140]
    This anti-backup plate 1112 pivots in a manner similar to that of a screen door lock that holds open a screen door when the anti-backup cam slot tube 1106 is closely spaced to the anti-backup cam tube 1114. Specifically, the anti-backup compression spring 1110 is able to act upon a top surface of the plate 1112 to tip the anti-backup plate 1112 to its locked position. Rotation of the anti-backup cam slot tube 1106 causes a distal camming movement of the anti-backup cam tube 1114 thereby forcing the top of the anti-backup plate 1112 distally, overcoming the force from the anti-backup compression spring 1110, thus positioning the anti-backup plate 1112 in an untipped (perpendicular), unlocked position that allows proximal retraction of the firing rod 1010.
  • [0141]
    With particular reference to FIG. 43, the traction biasing mechanism 1078 is depicted as being composed of a pawl 1116 that has a distally projecting narrow tip 1118 and a rightwardly projecting lateral pin 1120 at its proximal end that is rotatably inserted through a hole 1076 in the upper portion 230 of the firing trigger 20. On the right side of the firing trigger 20 the lateral pin 1120 receives a biasing member, depicted as biasing wheel 1122. As the firing trigger 20 translates fore and aft, the biasing wheel 1122 traverses an arc proximate to the right half piece 59 of the handle 6, overrunning at its distal portion of travel a biasing ramp 1124 integrally formed in the right half piece 59. The biasing wheel 1122 may advantageously be formed from a resilient, frictional material that induces a counterclockwise rotation (when viewed from the left) into the lateral pin 1120 of the pawl 1116, thus traction biasing the distally projecting narrow tip 1118 downward into a ramped central track 1075 of the nearest link 1072 a-d to engage the linked rack 1074.
  • [0142]
    As the firing trigger 20 is released, the biasing wheel 1122 thus fractionally biases the pawl 1116 in the opposite direction, raising the narrow tip 1118 from the ramped central track 1075 of the linked rack 1074. To ensure disengagement of the tip 1118 under high load conditions and at nearly full distal travel of the pawl 1116, the right side of the pawl 1116 ramps up onto a proximally and upwardly facing beveled surface 1126 on the rightside of the closure yoke 250 to disengage the narrow tip 1118 from the ramped central track 1075. If the firing trigger 20 is released at any point other than full travel, the biasing wheel 1122 is used to lift the narrow tip 1118 from the ramped central track 1075. Whereas a biasing wheel 1122 is depicted, it should be appreciated that the shape of the biasing member or wheel 1122 is illustrative and may be varied to accommodate a variety of shapes that use friction or traction to engage or disengage the firing of the end effector 12.

A coil 2011 is positioned around the firing bar 1022, and may be installed; for example, along the longitudinal recess 1014 of the firing trough member 1012 (see FIG. 41). As the knife 32 and cutting surface 1027 are reciprocated through the staple channel 22, the firing bar 1022 and magnet 2009 may move back and forth through the coil 2011. This motion relative to the coil induces a voltage in the coil proportional to the position of the firing rod within the coil and the cutting edge 1027 within the staple channel 22. This voltage may be provided to the memory device 2001, for example, via analog-to-digital converter 2018.

When no cartridge 34 is present, the contacts 2011, 2013 form an open circuit. When a cartridge 34 is present, the cartridge tray 1028 of the staple cartridge 34 contacts the contacts 2011, 2013, a closed circuit is formed. When the circuit is open, the sensor 2010 may output a logic zero. When the circuit is closed, the sensor 2010 may output a logic one. The output of the sensor 2010 is provided to memory device 2001, as shown in FIG. 44.
  • [0155]
    The cartridge condition sensor 2012 may indicate whether a cartridge 34 installed within the staple channel 22 has been fired or spent. As the knife 32 is translated through the end effector 12, it pushes the sled 33, which fires the staple cartridge. Then the knife 32 is translated back to its original position, leaving the sled 33 at the distal end of the cartridge. Without the sled 33 to guide it, the knife 32 may fall into lock-out pocket 2022. Sensor 2012 may sense whether the knife 32 is present in the lock-out pocket 2022, which indirectly indicates whether the cartridge 34 has been spent. It will be appreciated that in various embodiments, sensor 2012 may directly sense the present of the sled at the proximate end of the cartridge 34, thus eliminating the need for the knife 32 to fall into the lock-out pocket 2022.

    FIGS. 52A and 52B depict a process flow 2200 for operating embodiments of the surgical instrument 10 configured as an endocutter and having the capability to record instrument conditions according to various embodiments. At box 2202, the anvil 24 of the instrument 10 may be closed. This causes the closure trigger sensor 2002 and or the anvil closure sensor 2006 to change state. In response, the memory device 2001 may record the state of all of the sensors in the system 2000 at box 2203. At box 2204, the instrument 10 may be inserted into a patient. When the instrument is inserted, the anvil 24 may be opened and closed at box 2206, for example, to manipulate tissue at the surgical site. Each opening and closing of the anvil 24 causes the closure trigger sensor 2002 and/or the anvil closure sensor 2004 to change state. In response, the memory device 2001 records the state of the system 2000 at box 2205.
  • [0157]
    At box 2208, tissue is clamped for cutting and stapling. If the anvil 24 is not closed at decision block 2210, continued clamping is required. If the anvil 24 is closed, then the sensors 2002, 2004 and/or 2006 may change state, prompting the memory device 2001 to record the state of the system at box 2213. This recording may include a closure pressure received from sensor 2006. At box 2212, cutting and stapling may occur. Firing trigger sensor 110 may change state as the firing trigger 20 is pulled toward the pistol grip 26. Also, as the knife 32 moves through the staple channel 22, knife position sensor 2008 will change state. In response, the memory device 2001 may record the state of the system 2000 at box 2013.
  • [0158]
    When the cutting and stapling operations are complete, the knife 32 may return to a pre-firing position. Because the cartridge 34 has now been fired, the knife 32 may fall into lock-out pocket 2022, changing the state of cartridge condition sensor 2012 and triggering the memory device 2001 to record the state of the system 2000 at box 2015. The anvil 24 may then be opened to clear the tissue. This may cause one or more of the closure trigger sensor 2002, anvil closure sensor 2004 and anvil closure load sensor 2006 to change state, resulting in a recordation of the state of the system 2000 at box 2017. After the tissue is cleared, the anvil 24 may be again closed at box 2220. This causes another state change for at least sensors 2002 and 2004, which in turn causes the memory device 2001 to record the state of the system at box 2019. Then the instrument 10 may be removed from the patient at box 2222.
  • [0159]
    If the instrument 10 is to be used again during the same procedure, the anvil may be opened at box 2224, triggering another recordation of the system state at box 2223. The spent cartridge 34 may be removed from the end effector 12 at box 2226. This causes cartridge present sensor 2010 to change state and cause a recordation of the system state at box 2225. Another cartridge 34 may be inserted at box 2228. This causes a state change in the cartridge present sensor 2010 and a recordation of the system state at box 2227. If the other cartridge 34 is a new cartridge, indicated at decision block 2230, its insertion may also cause a state change to cartridge condition sensor 2012. In that case, the system state may be recorded at box 2231.
