Problems solved by technology

[0004] However, in the case of surgery using energy processing tools, air bubbles and fragments of tissue may remain in the liquid injected into the body after treatment, and the field of view when observing the surgical site with an endoscope deteriorates
[0005] In the case of the system disclosed in the aforementioned Japanese Patent Laid-Open No. 3-85173, a sensor for detecting the turbidity of the reflux liquid is provided, and the detection value of the sensor is used to increase the water supply volume of the reflux liquid, thereby securing the field of view. However, since the sensor for detecting turbidity is installed in the suction path, there is a time delay, and the turbidity of the reflux liquid cannot be removed quickly and appropriately, and there is a problem that it takes time to improve the field of view.
[0006] In addition, in the case of Japanese Patent Application Laid-Open No. 7-100203, the resected piece of living tissue is removed by increasing the liquid supply amount of the reflux liquid in conjunction with the output of the treatment energy. The amount increases, so there is a problem that it is difficult to handle
[0007] In particular, the technologies disclosed in the above two publications are aimed at ensuring the observation field of view during processing, and do not consider ensuring the field of view after processing, that is, after the processing energy output stops. In the technologies disclosed in the above two publications, , cannot quickly ensure a good field of view after processing
[0008] Furthermore, if the supply amount of the reflux liquid is suddenly reduced along with the stop of the energy output, there is also a possibility that the living tissue detached by the treatment may remain in the flow channel of the reflux liquid, and the channel may be clogged.

no. 1 Embodiment approach

[0028] 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 device 1 includes a treatment tool 11 , a power supply unit 12 , a liquid delivery unit 13 , and a suction unit 14 .

[0029] 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 includes a treatment unit 21 , a handle unit 22 , a vibrator unit 23 , a signal cable 24 , a liquid delivery tube 25 , and a suction tube 26 . The signal cable 24 is connected to the power supply unit 12 .

[0030] The treatment unit 21 is composed of a treatment unit 31 for treating a living tissue to be treated and an elongated sheath unit 32 . The treatment unit 31 includes a probe 31a and a movable member 31b as a jaw. The sheath portion 32 is a cylindrical membe...

Deformed example 1

[0078] In the above-mentioned embodiment, the reflux of the physiological saline by the pumps 47 and 49 after the energy output is stopped is performed by driving the pumps 47 and 49 at the same output level for a predetermined extended time. The higher output level drives the pumps 47, 49 for a predetermined extended time.

[0079] The configuration of the surgical device according to Modification 1 is the same as that of the above-mentioned first embodiment, and the processing of the CPU 41 is different from that of the first embodiment, so only the different configurations will be described.

[0080] Figure 4 and Figure 7 It is a flowchart showing an example of processing of the CPU 41 for controlling the HF output unit 44 and the pump drive units 46 and 48 in Modification 1. Figure 8 It is a timing chart of the output signal EOUT for high-frequency current output and the pump drive signals PiOUTs and PsOUTa of the pumps 47 and 49 in Modification 1. FIG.

Deformed example 2

[0093] In the above-mentioned first embodiment and modification 1, the extension time of both pumps 47 and 49 is the same time, but the extension time of the pump 49 as a suction pump may be longer than that of the liquid delivery pump 47 .

[0094] Figure 9 It is a timing chart of the output signal EOUT for high-frequency current output and the pump drive signals PiOUTs and PsOUTa of the pumps 47 and 49 in the second modification. Figure 9 This is the case where the extension time of the pump 49 serving as the suction pump is longer than the extension time of the liquid delivery pump 47 in the case of the first embodiment.

[0095] Such as Figure 9 As shown, in the case of the first embodiment, the pump drive signal PsOUTa of the pump 49 is output for a time longer than the pump drive signal PiOUTs of the pump 47 by a predetermined time Ta longer than the extension time Te.

[0096] Figure 10 This is another timing chart of the output signal EOUT for high-frequency cur...

Abstract

A surgical apparatus 1 includes a treatment portion 31, a high-frequency output portion 44 or the like that supplies energy such as a high-frequency current, a liquid feeding tube 25, a suction tube 26, two pumps 47 and 49, and a CPU 41 as a control portion. In response to stopping of the supply of energy from the high-frequency output portion 44 or the like, the CPU 41 controls the two pumps to be continuously driven for a predetermined extension time period after the supply of energy stops.

Description

technical field [0001] The invention relates to an operation device, in particular to an operation device capable of outputting energy. Background technique [0002] A surgical device using a surgical treatment tool is used to perform treatments such as coagulation and incision of living tissue. Surgical processors include various types of treatment tools such as a treatment tool that grips a living tissue or touches and processes a living tissue. In addition, surgical treatment instruments include ultrasonic treatment instruments capable of outputting ultrasonic vibrations, high-frequency treatment instruments capable of outputting high-frequency currents, and energy treatment instruments capable of simultaneously outputting ultrasonic vibrations and high-frequency currents in recent years. [0003] As disclosed in Japanese Patent Application Laid-Open No. 3-85173 and Japanese Patent Laid-Open No. 5-246959, there is a surgical device that performs energy processing while i...
