TW200822898A - Surgical stapling instrument having an electroactive polymer actuated single lockout mechanism for prevention of firing - Google Patents

Abstract

A surgical instrument includes an E-beam firing bar engages the channel and selectively engages the anvil during distal firing movements, wherein the tissue is severed and stapled driven upward from the staple cartridge to form against the anvil. In particular, a wedge integral to the staple cartridge is driven distally by a middle pin of the firing bar to effect stapling. A single lockout of the staple channel responds to the presence of the wedge sled in its unfired position to allow the firing bar to fire. Otherwise, the single lockout prevents firing when the staple cartridge is missing or spent. Further, some versions include an Electroactive Polymer (EAP) actuator that presents an abutting surface, or acts as a trapdoor to a ramped recess in a staple channel to block the firing bar, as an active approach to preventing firing for one or more conditions.

Since the distal end of the angled end 282 is lower than the proximal end of the collared end 282, the middle pin 46 of the firing rod μ can be forced over the inclined end 282 to force them down into the hook recess The slot 288 straight 24 200822898 to the middle pin 46 passes through the tilted end 282, as shown in Fig. 34, wherein the tilting-tilt end 282 will spring back in a rebound manner to block the middle pin 46. / Thus, 'the exhausted U-shaped When the staple cartridge 37 is replaced with the unfired staple clamp 37, the firing rod 14 can be prevented from moving distally. The electrically actuated polymer a electrically actuated polymer (EAP) is a group that changes when applied voltage. Shaped doped conductive polymer. Essentially, the conductive polymer is paired into a certain ion or colloid and electrode form. The flow of ions from the fluid/colloid into or out of the conductive polymer is induced by an applied voltage and this A flow will induce the shape of the polymer to change. Depending on the polymer used and the ion current, the voltage is between 1V and 4kV. There is this pa PA two r-丄 shoulders and two ^^^ When it shrinks, it will swell. It can be combined with mechanical components (for example, The magazine pairing is used to change the effect when there is an applied voltage. ~丨板) 15 20 There are two county EAPW (four) recording configurations. These two basic types are fiber bundles and laminated variants. Fiber composition of about % to = fiber can be woven into a bundle like a fabric and is often _ -1 til This type of EAP shrinks when there is an applied voltage. Electrode = central core and guide (4), the conductive material Also used

= ionic fluid of the beam. An example of the city Qianwei EAP material is manufactured by Fe SC峨d technology and is sold under the trademark PA: Wen-type is a layered structure of 'EAp polymer', layered 25 200822898 sub-colloids with two added to the stack A flexible board with two sides of the layer. When a voltage is applied, the square abundance plate will expand in one direction and contract in the vertical direction. An example of a commercially available layer (plate) crucible material is manufactured by the SIU Laboratories division of the company. The platy EAp material is also available from EAMEX of 曰本本 and is referred to as film EAp. It should be noted that ΕΑΡ when energized* will change volume and only contract or expand laterally when expanding or taking care in one direction. It is possible to make (4) the basic form of the layered variant as - the surface is leaning against the difficult structure and the other side is leaning against the piston. Laminated variants can also be applied to both sides of the slab. When the surface of the flexible board EAp towel is energized, the board swells and the board deflects in the opposite direction. This allows the board to flex in both directions depending on which side is energized. ΕΑΡ Actuation H usually consists of a number of fibers added to the layer or bundle that cooperates. The mechanical _ will determine the ΕΑρ actuator and its motion performance. ΕΑΡ can form long strips and lining the single-spot central electrode. The smear outer jacket forms the other electrode of the filament and contains the ionic fluid required for I. In this configuration, the #1 field is applied to the electrodes and the line is short k. This age of ΕΑΡ actuation n is called fiber EAp to actuate crying. Similarly, the laminate configuration can place a number of layers on either side of the flexplate or only the layers themselves to increase its performance. Typical fiber structures have an effective strain of 2 to 4 percent, where a typical laminate variant of higher voltage is used 2 to 30%. For example, a laminated EAp composition can be formed by a positive electrode plate electrode layer attached to the E A ruthenium layer, followed by adhesion to an ion battery layer ‘and then attached to the negative electrode plate electrode layer. The multi-layer laminate composite can be fixed in a stack by an adhesive layer. 200822812898 = Formation of a crucible plate actuator. It will be appreciated that opposing Εαρ actuators that are selectively bendable in both directions can be formed. The ΕΑΡ_actuator may comprise a longitudinal white gold cathode wire which is a long cylindrical cavity in the wall of the two pillars which penetrates the insulating polymer and is electrically conductively doped to serve as a positive anode. The distal end of the white total cathode line is embedded in the distal end of the insulating polymer, arranged in parallel and _ cathode line and the end 10 is attached around each end cover to surround the cylindrical cavity to seal the ions between the polymer fiber and the cathode line. When a voltage is applied through the plastic cylindrical wall (anode) and the cathode line, the ion:body:=reduced polymer fiber' causes the outer diameter to become larger and the length to contract correspondingly to cause the end caps to pull each other. 15 In Figure 1, the surgical stapling and cutting instrument 510 is opened, wherein

The E-bar 512 is fully pulled back into the nail assembly 514. During assembly, the lower leg portion 516 of the E-bar 512 falls through the widened aperture 518 of the staple slot 520 of the needle assembly 5M. Then, the E-shaped rod 512 is advanced so that the £-shaped rod 512 is formed along the other way of the squatting groove, and the lower rail milk contains a narrow narrow slit, which is opened under the u_; The slit 526 is formed to form a ϋT-shaped cross section that communicates with the widened hole 518. After assembly, the proximal end is lightly coupled to the firing, and the assembly of the f-bar 512 does not allow the lower leg to re-adjust to the proximal end _ the boring 518 to allow disengagement. 27 200822898 Please refer to the 35 ® to the % map. The E 5 rods of the E-type rods are slid along the front of the U-shaped nail card g 52 〇 to the lower side of the lower tang. It is slidably engaged with the staple groove 52〇. The upper latch 532 of the E-bar 512 resides in the stone pocket 534 (Fig. 36) when pulled back to the proximal end, which allows for repeated opening, closing of the upper jaw, or hitting of the assembly 514. Gu 536 responds to the closing motion of the closed sleeve assembly MS in the horseshoe shaped aperture 54 that fits the closure feature 542 of the stone occupying limb 536. The stone 536 series has a proximal pivot pin 544 as a vehicle, and the straight center rock pivot pin 544 can slide in the other 546 of the u-shaped groove (Fig. 36 is shown by a dashed line ). In the 36th view, the proximal firing pin 528 of the E-bar 512 includes a downward projection 548 that slides against the staple groove 520, which facilitates raising the distal end when pulled back. The E-bar 512 facilitates the preparation of the nailing assembly 514 for insertion through, for example, a trocar and a central latch 530 for accessing the iliac actuating securing mechanism 55A. In Figures 37 to 38, the Ε-shaped rod 512 has moved distally at the beginning of the firing. The upper latch 532 enters a widened anvil 552 that is formed in the anvil 536 and communicates with the anvil pocket 534. The narrowed anvil slit 554 in vertical communication with the anvil 552 allows the cutting surface 556 of the Ε-shaped rod 512 to pass through the u-shaped nail card for cutting the anvil 536 and engaging the staple groove 〇2匣 558 organization between. The engagement surface 560 of the ε-shaped rod 512 between the cutting surface 556 and the middle pin 530 is adjacent to the wedge-shaped slide 562 (Fig. 1). The wedge-shaped slide 562 is integrated into the staple clip 558 and is initially in the staple card.匣 558 near the end. It should be understood that the wedge slide 562 will cause the dowel 28 200822898 drive 564 to be camed upward.

The hole 568 on the staple driver 564 is formed by the U-top body 536. 566 has also been cam-up upward so that the firing rod 528 is far away from the ^ ^ i οσ ^ in the extended portion of the 572 will accept the 5 6 ^ 1G part of the 58 ° long shaft 578 The frame lower projection spring 574 is pressed toward T. In the firing stroke, the widening hole 518 and the middle (four) 530 are close to εαρ to actuate 572疋=touching, and during the first minute, the swaying elastic 574 and the heightening part of the box bomb # ϋ are opposite each other. Therefore, during this, during the firing stroke portion, it is helpful for the i:= to move the latch 530 down into the inclined groove 591 forming the (four) shaped groove temple 520.

The grooves 691 are aligned (the fourth drawing is shown by a broken line as 692,). Therefore, the proximal end of the ΕΑΡ plate actuator 692 has an abutment surface 693 that can absorb the firing force of the middle pin 530, so that the stalk rod 5 = 29 200822898 squeezing force 10 15 20 straight to the king yoke scented slab - slab Ejected Eap Actuation Fixing Mechanism In Figures 40 through 41, the surgical stapling and cutting instrument 71 is the same as described above in Figures 35 through 38, except for the often aligned Eap actuation mechanism 750. The EAp plate actuator 592, which is used at the proximal end and actuated downward, becomes a trapdoor to open the inclined groove formed in the staple groove 72〇 and can be actuated to bend downward to close the tilt A groove 791 (shown as a 792 in phantom in Figure 40) is used to allow firing. Therefore, the abutment surface 793 at the distal end of the inclined groove absorbs the firing force of the pin 53 of the E-shaped rod 512 to prevent firing. The governor draws the electrician. It should be understood that the control circuit in the handle part is beneficial to respond to the command of the money (4) by sensing the invalidity of the key, such as sensing the missing staple jam.
