Description

  The present invention relates to a surgical instrument that applies medical treatment by applying energy to living tissue.

  Conventionally, various types of surgical tools that are driven by electricity have been known. For example, an ultrasonic surgical device that cuts and coagulates living tissue using ultrasonic vibration, or a living tissue that uses high-frequency power. Monopolar (bipolar) and bipolar (bipolar) type high-frequency treatment tools that allow or solidify, a thermal scalpel device that cuts through living tissue using heat, and crushing and sucking living tissue using ultrasonic vibration And an excision device that pulverizes a living tissue using a rotational force such as a drill. Furthermore, recently, a battery-type surgical instrument has also been proposed in which a battery is loaded into an electrically driven surgical instrument to remove the power cable to improve operability.

  As an example of such a surgical tool, for example, in Japanese Patent Publication No. 2-43501, a drill for crushing living tissue is provided at the tip of a probe, and a motor for supplying a rotational driving force to the drill and an electric power for the motor are provided. A cutting device having a configuration in which a battery to be supplied and a switch for operating the motor is provided in a gripping portion is shown.

  However, in Japanese Patent Publication No. 2-43501 cited in the prior art, although means for operating the energy output from the surgical tool is shown, output level adjustment for adjusting the output level of the energy output from the surgical tool. Means for performing the operation are not shown, and in the configuration as it is, for example, since the rotational driving force of the motor cannot be adjusted, the amount of pulverization of the living tissue cannot be adjusted. Further, if the means for performing the output level adjustment operation is simply added in addition to the means for performing the operation operation, the operation means for the operation operation and the output level adjustment operation are separately provided, and the operation becomes complicated. Oops. In addition, depending on the surgical tool, there are not only operations for energy output, but also operations such as sandwiching a target biological tissue to output energy. Thus, means for performing operations other than the operation for energy output are provided. When added, the operation was further complicated.

  In general, since a battery-type surgical instrument having a built-in battery is excellent in portability, it is expected to be used for medical activities in a highly urgent scene such as a disaster area or a battlefield. However, the battery-type surgical instrument has a drawback that if the battery is discharged and the capacity becomes insufficient, it takes time to replace the battery, or it cannot be used continuously if a replacement battery is not secured. It was a hindrance to use in highly urgent situations.

  The surgical instrument of the present invention is a surgical instrument having a treatment part that makes a medical treatment by contacting or approaching a treatment target site, which is a living tissue, and applying energy to the treatment target site. An energy supply unit for outputting; an operation gripping unit disposed on a proximal end side of the treatment unit; and a battery disposed on the operation gripping unit for supplying electric power for driving at least the energy supply unit. It is characterized by that.

  ADVANTAGE OF THE INVENTION According to this invention, even if a battery discharges and capacity | capacitance runs short, the portable surgical tool which can be used continuously can be provided.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 to 3 relate to a first embodiment of the present invention, FIG. 1 is an explanatory view showing the overall configuration of the surgical instrument, FIG. 2 is an enlarged view around a jog dial of an operation unit, and FIG. 3 is a configuration of an electric system FIG.

  As shown in FIG. 1, a surgical tool 1 that is a battery-type ultrasonic coagulation / cutting device that performs a coagulation treatment and an incision treatment on a treatment target site by ultrasonic waves using a built-in battery as a power source is an elongated insertion inserted into a body cavity or the like. A rotation knob 3 which is provided at a base end portion of the insertion portion 2 and rotates the outer periphery to rotate the insertion portion 2, and the rotation toward the proximal end side of the insertion portion 2. An operation unit 4 that is rotatably connected via the knob 3 to grip and operate the surgical instrument 1, an ultrasonic transducer 11 that is provided in the operation unit 4 and generates ultrasonic waves, and an operation A horn 12 connected to the front end of the ultrasonic transducer 11 in the section 4 and formed in a substantially tapered shape for amplifying the amplitude of the ultrasonic wave emitted from the ultrasonic transducer 11, and the front end of the horn 12 Is inserted in the insertion portion 2 and forward from the distal end of the insertion portion 2 A probe 13 that protrudes and transmits ultrasonic waves to the protrusion, a jaw 14 that is rotatably provided to face the protrusion of the probe 13, and the insertion portion 2 and the operation portion 4 are inserted. A driving rod (not shown) that rotates the jaw 14 by advancing and retreating, and a rotating rod that is provided in the operation unit 4 and that rotates the jaw to move back and forth by rotating the jaw 14. A lever 15, a drive circuit 16 that is provided in the operation unit 4 and drives the ultrasonic transducer 11, and a battery that is provided in the operation unit 4 and is a power source that supplies power to at least the drive circuit 16. 17, a jog dial 18 that adjusts the output level of the drive circuit 16 by rotating, and activates the output of the drive circuit 16 by pressing toward the operation unit 4, Provided part 4 is configured by a display device 19 which is composed of, for example, LED displays the output level set by the jog dial 18 (light emitting diode).

  Note that a non-illustrated compliant member made of, for example, Teflon (registered trademark) may be provided at a contact portion between the protruding portion at the tip of the probe 13 and the jaw 14.

  As shown in FIG. 2, the lever 15 is disposed at a position where it can be operated with, for example, an index finger or a middle finger when the operation unit 4 is gripped, and the jog dial 18 is operated when the operation unit 4 is gripped. The display device 19 is disposed at a position where it can be operated with a thumb. The display device 19 is disposed at a position that is easy to see when the operation unit 4 is gripped, for example, in front of the jog dial. Thus, the operation unit 4 can be gripped and the lever 15 and the jog dial can be operated with one hand.

  As shown in FIG. 3, the jog dial 18 detects an angle of rotation of the jog dial 18 and supplies the rotation angle information to the drive circuit 16 and the display device 19, and a pressing operation on the jog dial 18. And a switch 18b that opens and closes when it is detected.

  The drive circuit 16 uses a drive signal oscillation circuit 16a that oscillates a signal for driving the ultrasonic transducer 11 and a rotation angle information from the encoder 18a to operate according to the state of the switch 18b of the jog dial 18. Accordingly, a drive signal amplifying circuit 16b that adjusts the output level of the signal obtained by the drive signal oscillation circuit 16a and applies the signal to the ultrasonic transducer 11 is configured.

  Next, the operation of the present embodiment will be described.

  First, the insertion portion 2 is inserted into the body through a trocar tube (not shown), and the tissue of the treatment target site to be subjected to coagulation treatment or incision treatment is sandwiched between the protruding portion of the probe 13 at the distal end of the insertion portion 2 and the jaw 14. At this time, by rotating the lever 15 of the operation unit 4 so as to be pulled toward the hand side with, for example, an index finger or a middle finger, a drive rod (not shown) inserted through the insertion unit 2 advances and retreats in the axial direction, and the jaw 14 is closed. The tissue is sandwiched between the jaws 14. Note that the jaw 14 is adjusted to a desired opening angle by the rotation angle when the lever 15 is rotated.

  Next, when the jog dial 18 is rotated with, for example, the thumb of the hand holding the operation unit 4 while maintaining the state where the tissue is sandwiched between the jaws 14 by pulling the lever 15 toward the hand side, the rotation of the jog dial 18 is performed. The moving angle is detected by the encoder 18a, and the rotation angle information obtained by the encoder 18a is given to the drive signal amplification circuit 16b. The gain of the drive signal amplification circuit 16b is adjusted according to the rotation angle information, and the drive is performed. The output level of the drive signal given from the circuit 16 to the ultrasonic transducer is adjusted to a desired output level, and the output level of the ultrasonic vibration given from the tip of the probe 13 to the tissue is adjusted to a desired level. At this time, the surgeon can set the output level to a desired level by rotating the jog dial 18 while confirming the value of the output level displayed on the display device 19.

  When the output level is set to the desired output level, when the jog dial 18 is pushed in the direction of the rotation axis of the jog dial 18, that is, when the jog dial 18 is pushed into the operation unit 4, the switch 18b that detects this operation is detected. The open / closed state is applied to the drive signal oscillation circuit 16a, and the drive signal oscillation circuit 16a receiving power supply from the battery 17 is operated to output a drive signal. The drive signal has a gain corresponding to the output level. Amplified by the drive signal amplifying circuit 16 b and applied to the ultrasonic transducer 11. Then, the ultrasonic transducer 11 given the drive signal oscillates ultrasonic waves, and the ultrasonic waves are amplified by the horn 12 and transmitted by the probe 13 to the protruding portion at the tip of the probe 13. The biological tissue sandwiched between the protruding portion of the probe 13 and the jaw 14 is heated by heat generated by ultrasonic vibration, and a coagulation treatment or an incision treatment is performed on the biological tissue including blood vessels.

  As described above, according to the present embodiment, not only can the operation of the output of the ultrasonic energy from the surgical instrument 1 be instructed, but also the output level of the ultrasonic energy output from the surgical instrument 1 is set and adjusted. be able to.

  Further, the output operation operation and the output level adjustment operation are both performed by the jog dial 18 which is the same operation means, and these operations can be performed with one finger, and the operability is excellent.

  Further, the grip of the operation unit 4 and the operation of the jog dial 18 can be performed with one hand.

  In addition, since fingers other than the finger that operates the jog dial 18 of the hand that holds the operation unit 4 are retained, the lever 15 can be operated with these retained fingers. Further, since the other hand is retained with respect to the hand that holds the operation unit 4, it is possible to operate the rotary knob 3 or perform operations other than the surgical instrument 1 with the retained hand.

  Therefore, according to the present embodiment, it is possible to perform the operation operation for operating the energy output from the surgical instrument 1 and the output level adjustment operation for adjusting the output level of the output energy with one finger. In addition, the surgical tool 1 can be grasped, actuated, and output level-adjusted with one hand, and a finger for performing other operations except the actuating operation and the output level is retained. The effect that property improves is acquired.

  Further, since the output can be started after the output level is set to a desired level, the period during which the output level is unstable until the output level reaches the desired level is short. Therefore, the period from when the operation instruction is given until the desired output level is obtained is short, and the followability is good.

  Further, after the output level is set to a desired level, an operation for maintaining the output level setting constant is not required, so that the output level is stably maintained. The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the invention.

  For example, the surgical tool is not limited to an ultrasonic coagulation / cutting device, as long as it is an electrically driven surgical command that adjusts the operation level and output level, but is not limited to the ultrasonic coagulation / cutting device. A female device or the like may be used.

  In addition, for example, the surgical instrument is not limited to the one in which the battery is incorporated in the main body of the surgical instrument, and even those that receive power supply from the outside are within the scope of the present invention. In addition, operability including portability is improved by incorporating the battery in the main body of the surgical instrument.

  By the way, in general, a battery-type surgical instrument having a built-in battery is excellent in portability, and therefore, it is expected to be used for medical activities in a highly urgent scene such as a disaster area or a battlefield. However, the battery-type surgical instrument has a drawback that if the battery is discharged and the capacity becomes insufficient, it takes time to replace the battery, or it cannot be used continuously if a replacement battery is not secured. There was a hindrance to use in highly urgent situations.

  An example of a portable surgical instrument that can be used continuously even when the battery is discharged and its capacity is insufficient or even without a battery will be described with reference to FIGS.

  As shown in FIG. 4, a surgical instrument 51 that is a battery-type ultrasonic scalpel is connected to an insertion portion 52 to be inserted into a body cavity or the like, and a proximal end side of the insertion portion 52, and holds the surgical instrument 51. A grip 52, a sheath 52a that covers the insertion portion 52 and has a proximal end detachably fitted to the outer periphery of the distal end of the grip 53, and is detachably attached to, for example, the proximal end of the grip 53. , A handle 61 that is rotated by hand, and is provided in the grip 53. An electromotive force generator 62 that generates power by rotating the handle 61, and a handle 62 that is provided in the grip 53. A battery 63 that stores the electric power generated in 62, and a drive circuit 64 that is provided in the grip 53 and receives a power supply from the battery 63 and generates a drive signal for generating ultrasonic waves. The ultrasonic vibrator 65 provided in the grip 53 and driven by the drive circuit 64 to generate ultrasonic waves, and the amplitude of the ultrasonic wave provided in the grip 53 and emitted from the ultrasonic vibrator. A horn 66 that amplifies the sound, a probe 67 that is inserted through the insertion portion 52 and transmits ultrasonic waves output from the horn 66 to the distal end of the insertion portion 52, and is integrated with the distal end of the probe 67. The hook portion 68 is formed so as to protrude from the distal end of the insertion portion 52, and the switch 69 is provided on the grip 53 to operate the ultrasonic output.

  As shown in FIG. 5, the drive circuit 64 performs, for example, voltage conversion or voltage stabilization on the power supplied from the battery 63, and supplies power to each part of the drive circuit 64. A drive signal generation circuit 64b for generating a drive signal for driving the ultrasonic transducer 65 is provided. The drive circuit 64 is activated by the operation of the switch 69.

  The power generator 62 shown in FIG. 4 is not limited to the induced electromotive force type power generator, and may be a power generator 71 configured as shown in FIG. 6, for example. The power generator 71 shown in FIG. 6 includes a heat generation source 71a that generates heat by rotating the handle 61, and a heat-electric converter 71b that converts heat generated by the heat generation source 71a into electricity. It is configured.

  Next, the operation of the surgical tool 51 will be described.

  When the handle 61 is rotated, this rotational kinetic force is converted into electric energy by the power generator 62, and this electric energy is stored in the battery 63.

  Next, for example, the hook portion 68 is brought into contact with the living tissue so as to be hooked to suppress bleeding from the living tissue that is the treatment target site, and the switch 69 is operated. Then, the drive circuit 64 that receives power supply from the battery 63 drives the ultrasonic transducer 65, and the ultrasonic wave emitted from the ultrasonic transducer 65 is amplified by the horn 66 and is hooked through the probe 67. The living tissue is excised while the bleeding from the living tissue with which the hook portion 68 contacts is suppressed by the heat generated in the hook portion 68 due to the ultrasonic vibration.

  Here, when the capacity of the battery 63 is insufficient, the handle 61 is rotated again, the battery 63 is charged, and the surgical instrument 51 is continuously used. Note that the handle 61 is not only operated by the operator of the surgical instrument 51, but may be operated by, for example, a nurse whose hands are sterilized in the same manner as the operator. Further, the handle 61 may be operated with a light force by forming a large turning radius. Further, the portability may be improved by reducing the turning radius of the handle 61.

  According to the portable surgical instrument described above with reference to FIGS. 4 to 6, it is possible to obtain an effect that the battery can be continuously used even if the battery is discharged and the capacity is insufficient or the battery is not used.

  The surgical instrument 51 is an ultrasonic scalpel which is an example of a surgical instrument. However, the surgical instrument is not limited to this, and any surgical instrument that is portable and electrically driven can be used. For example, a scissors (scissors) type May be an ultrasonic coagulation / cutting device, an ultrasonic suction device, a monopolar and bipolar high-frequency treatment instrument, a thermal knife, or the like.

  By the way, in recent years, a probe having an ultrasonic transducer that transmits and receives an ultrasonic beam at the tip is inserted into the body, and the reflected wave is reflected on the boundary surface of biological tissue with different acoustic impedance. 2. Description of the Related Art Ultrasonic observation apparatuses that image an echo signal obtained from the above and display the obtained ultrasonic image on a display device to observe an affected area are widely used. In such an ultrasonic observation apparatus, for example, as shown in Japanese Utility Model Application No. 56-150721, a trocar in which an insertion hole for guiding a probe into the body is formed is punctured into a body wall, and the trocar is inserted through the trocar. Then, the probe is inserted into the body and the affected part is observed with ultrasound.

  However, as shown in Japanese Patent Application No. 56-150721, when a probe is introduced into the body via a trocar, while the affected part is being observed by this probe, other treatment tools and internal In order to introduce other treatment tools or endoscopes into the body during ultrasound observation, puncture other trocars into the body wall and attach the treatment tools or endoscopes. It will be introduced into the body and will invade the patient accordingly.

  Therefore, an example of an ultrasonic observation apparatus that enables a minimally invasive treatment or inspection by allowing other treatment tools, endoscopes, and the like to be introduced into the body through a trocar used for ultrasonic observation is illustrated. 7 and FIG.
