However, sometimes when the treatment is repeated, the waterproof coating of the treatment part is peeled off, and dirt caused by burnt etc. adheres to the surface of the treatment part, resulting in the adhesion of living tissue to the treatment part.
[0008] When biological tissue adheres to the treatment part, the surgeon cannot confirm that the treatment is complete
Specifically, when the biological tissue adheres to the treatment part, the surgeon cannot observe the treatment state of the biological tissue even if the scissor-shaped clamping part is opened.
In addition, when living tissue adheres to the treatment part, the severed blood vessel cannot be separated from the clamping part, so the surgeon cannot confirm the cutting of the blood vessel.
[0009] In addition, there are also cases where, although the incision treatment is completed, the surgeon continues to output the incision treatment because the living tissue adheres to the treatment part and the blood vessels and the like do not leave the treatment instrument, so that there is a speed-up. The problem of wear and tear of the electrode plate of the disposal part
[0010] In the above-mentioned three U.S. patent publications, no consideration is given to the problem that the living body tissue adheres to the treatment part when the energy output for the treatment ends and the surgeon cannot confirm the completion of the treatment.

[0023] figure 1 It is a figure for demonstrating the structure of the surgical apparatus which concerns on 1st Embodiment of this invention. Such as figure 1 As shown, the surgical apparatus 1 is configured to include a treatment instrument 11 , a power supply unit 12 , and a liquid delivery unit 13 .
[0024] The treatment instrument 11 is a scissors-shaped surgical treatment instrument capable of outputting at least one of ultrasonic vibration energy and high-frequency current energy. The treatment instrument 11 is configured to include a treatment unit 21 , a handle unit 22 , a vibrator unit 23 , a signal cable 24 , and a liquid feeding tube 25 .
[0025] The treatment unit 21 is composed of a treatment unit 31 for treating living tissue and an elongated sheath unit 32 . The treatment unit 31 has a probe 31a and a movable member 31b as a jaw member. The sheath portion 32 is a cylindrical member through which a shaft member for opening and closing the probe 31a, the mova...

[0067] In the above-mentioned first embodiment, the CPU 41 drives the pump 47 to start liquid delivery in conjunction with the stop of the energy output. , press the liquid delivery tube 25 or the liquid delivery tube 21b mechanically to limit the liquid delivery, and start the liquid delivery when the clamping operation is released.
[0068] Figure 6 It is a figure for demonstrating the structure of 1 A of surgical apparatuses concerning this embodiment. exist Figure 6 in, right with figure 1 The same reference numerals are assigned to the same constituent elements, and description thereof will be omitted.
[0069] In the surgical apparatus 1A, the movable handle 36b1 of the treatment tool 11A has a protrusion 51 that abuts on the liquid feeding tube 21b to deform the liquid feeding tube 21b when the handle portion 36A is closed. In addition, a receiving member 52 for receiving the liquid feeding tube 21 b deformed by the protrusion 51 is fixedly provided in the fixed han...

[0095] In the above-mentioned two embodiments, the liquid feeding is performed for a predetermined time after the energy output is completed, but instead of the predetermined time, the liquid feeding of a predetermined amount may be performed. That is, the CPU 41 may control the pump 47 so as to deliver a predetermined amount of liquid that contains enough moisture in the living tissue dried by the energy treatment so as not to adhere to the treatment instrument.
[0096] In this case, the information on the liquid delivery amount, which is a predetermined amount, is also stored in the storage unit 42 , and is set differently according to the detected impedance as in the two embodiments described above. In addition, the operator can set and change the value of the liquid delivery amount stored in the storage unit 42 .

Abstract
A surgical 1 apparatus includes: a treatment section 31 for treating a living tissue; an ultrasound output section 43 and a high-frequency output section 44 that generate energy for providing ultrasound vibration or high-frequency current to the treatment section 31; a liquid feeding tube 25 and a tube 21b for feeding a liquid; an opening portion 21a, provided in the treatment section 31, for feeding the liquid from the liquid feeding tube 25 and the tube 21b in order to feed the liquid to between the living tissue and the treatment section 31; a pump 47 for supplying the liquid to the liquid feeding tube 25 and the tube 21b; and a CPU 41. The CPU 41 controls the pump 47 so that in connection with stoppage of an output of the energy from the ultrasound output section 43 and the high-frequency output section 44, the liquid is supplied from the pump 47 for a predetermined period of time or in a predetermined amount after the stoppage of the output of the energy.
Description
technical field [0001] The present invention relates to a surgical device, in particular to a surgical device capable of outputting at least one of ultrasonic vibration output and high-frequency current output. Background technique [0002] Surgical treatment tools are used for coagulation and incision of living tissue during surgery. Surgical treatment instruments include those of a type (so-called scissors-shaped type) that sandwich and treat living tissue. In addition, among surgical treatment instruments, for example, an ultrasonic treatment instrument capable of outputting ultrasonic vibrations and a high-frequency treatment instrument capable of outputting high-frequency current are known. and energy processing appliances with high-frequency current output. [0003] In the scissors-shaped ultrasonic treatment instrument, one member vibrates ultrasonically, and the other jaw member opens and closes to hold the one member. In addition, in the scissors-shaped high-freq...
