The user can perform a cutting operation by pressing the cutting button 104 to cut the target tissue at the surgical site. The user can perform an ablation operation by pressing the ablation button 105, so as to perform ablation or coagulation treatment on the target tissue at the surgical site. Those skilled in the art should understand that one or more of the above-mentioned operation keys may be provided on the control part 101, and other operation keys may also be provided to realize other functions.

The shaft 107B is the connecting part between the control part 101 and the monopole assembly. Various pipelines, cables, linkage mechanisms and related components (not shown) can be arranged in the shaft to achieve power transmission, signal transmission, fluid delivery and suction, and electrode translation and rotation.

The unipolar assembly includes a tubular member 107A, a valve member 108, and a unipolar electrode 109. The tubular member 107A may be a separate member coupled to the shaft 107B. Alternatively, the tubular member 107A may be constructed integrally with the shaft 107B. The valve member 108 is disposed in the tubular member 107A adjacent to the distal end of the tubular member 107A or at the distal end of the tubular member 107A. The monopolar electrode 109 is at least partially disposed within the tubular member 107A. As shown in the figure, the monopolar electrode 109 is a hook electrode. Alternatively, the monopolar electrode 109 may be a shovel electrode.

In order to clean the monopolar electrode 109 during the operation, a cleaning part 111 configured to clean the monopolar electrode 109 is provided in the inner cavity of the tubular member 107A. The unipolar electrode 109 can be retracted along the longitudinal axis in the retracted position of the electrode head in the cleaning part 111 (see FIG. 4B) and the extended position where the electrode head can be extended distally from the tubular member 107A so as to be able to perform surgical operations ( See Figure 3B) for translational movement between. As shown in the figure, the control part 101 may include a driving part 106 configured to drive the unipolar electrode 109. The driving part 106 is coupled to the monopolar electrode 109 through a linkage mechanism provided in the tubular member 107A and the shaft 107B so as to drive the monopolar electrode 109 to translate between the extended position and the retracted position. Preferably, the driving part 106 is a manual wheel that can perform a push-pull operation along the longitudinal axis, so as to drive the monopolar electrode 109 to perform a translational movement between the extended position and the retracted position along the longitudinal axis.

Specifically, in the case where the driving part 106 is a manual runner, the manual runner may be integrally coupled with the tubular member 107A and the shaft 107B. Thus, by pushing the manual wheel distally, the tubular member 107A and the shaft 107B translate distally accordingly, so that the electrode head can be retracted proximally to the retracted position relative to the tubular member 107A and the shaft 107B. In addition, by pulling back the manual wheel proximally, the tubular member 107A and the shaft 107B translate proximally accordingly, so that the electrode head can protrude distally to the extended position relative to the tubular member 107A and the shaft 107B. Those skilled in the art should understand that the manual runner is only a feasible implementation, and the driving part 106 can take any other form different from the manual runner, as long as the unipolar electrode 109 can be extended along the longitudinal axis through the driving part 106. The translational movement between the position and the retracted position is sufficient.

Referring to FIG. 3B, when the monopolar electrode 109 is in the extended position, the control part 106 can control the monopolar electrode 109 to perform a surgical operation. For example, the operator can perform the flushing operation, the suction operation, the cutting operation, and the ablation of the unipolar electrode 109 by pressing the flush button 102, the suction button 103, the cutting button 104, and the ablation button 105 respectively as described above. operate. At this time, the valve member 108 is opened, and the inner cavity of the tubular member 107A is in communication with the external environment. Therefore, when a large amount of smoke is generated in the operation area and the surgeon's field of view becomes blurred, the user can press the suction button 103 to perform a suction operation, thereby inhaling the generated smoke while activating the monopolar electrode 109.

Referring to FIG. 4B, when foreign objects such as viscous tissue and eschar are attached to the electrode head, which affects the normal operation of the monopolar electrode 109, the monopolar electrode 109 needs to be cleaned. In this case, the user can operate the driving part 106 to retract the monopolar electrode 109 to the retracted position as shown in the figure through the linkage mechanism. When the unipolar electrode 109 is in the retracted position, the valve member 108 is closed, thereby sealing the distal end of the cleaning part 111 and the cleaning operation of the unipolar electrode 109 can be performed in the cleaning part 111.

Specifically, the cleaning operation of the monopolar electrode 109 includes washing the electrode head with the pressurized fluid from the control part 101 in the cleaning part 111, and the high temperature electrode head can be cooled by such washing. After the rinsing is completed, the contaminated fluid is drawn from the cleaning part 111. Since the distal end of the cleaning part 111 has been closed by the valve member 108, the cleaning part is isolated from the patient's internal environment during the cleaning process, and the pressurized fluid used to wash the electrode head will not leak into the patient's body, thereby enabling Avoid contaminating the surgical site in the patient's body. Preferably, the pressurized fluid used to rinse the electrode head is physiological saline.

In addition, when the monopolar electrode 109 is in the retracted position, the driving part 106 can drive the monopolar electrode 109 to rotate around the longitudinal axis during the cleaning operation of the monopolar electrode 109, thereby performing rotary cleaning on the monopolar electrode 109. In the case where the driving part 106 is a manual wheel, the operator can rotate the manual wheel around the longitudinal axis so as to drive the monopolar electrode 109 to rotate around the longitudinal axis, thereby performing rotary cleaning on the monopolar electrode 109. Such a rotary cleaning operation can better remove foreign matter attached to the electrode head and further improve the cleaning effect.

In addition, as shown in FIGS. 3B and 4B, an auxiliary cleaning feature 110 may be provided on the inner wall of the cleaning part 111, and the auxiliary cleaning feature 110 can help to remove foreign matter attached to the monopolar electrode 109. Preferably, the auxiliary cleaning feature 110 may be an annular metal knurled texture provided on the inner wall of the cleaning part 111. Alternatively, the auxiliary cleaning feature 110 may also be an elastic brush pad provided on the inner wall of the cleaning portion 111. As shown in FIG. During the cleaning operation, the operator can drive the monopolar electrode 109 to translate or rotate in the cleaning part 111 by operating the driving part 106. Therefore, the auxiliary cleaning feature 110 can help clean the monopolar electrode 109 through friction. Foreign matter attached to the surface.

Specifically, in the case where the driving part 106 is a manual runner, the manual runner may be integrally coupled with the tubular member 107A and the shaft 107B. Thus, by rotating the manual wheel about the longitudinal axis, the tubular member 107A and the shaft 107B rotate about the longitudinal axis accordingly, thereby enabling the electrode head to rotate relative to the tubular member 107A and the shaft 107B. Thereby, the monopolar electrode 109 can be rotationally cleaned by the auxiliary cleaning feature 110 provided on the inner wall of the cleaning part 111. Those skilled in the art should understand that the manual runner is only a feasible implementation, and the driving part 106 can take any other form different from the manual runner, as long as the unipolar electrode 109 can pass through the driving part 106 when the unipolar electrode 109 is in the retracted position. It is sufficient to realize the relative rotation between the monopolar electrode 109 and the auxiliary cleaning feature 110 for rotary cleaning.

In this embodiment, the valve member 108 is a ball valve that can be opened in response to the unipolar electrode 109 being moved to the extended position, and can be closed in response to the unipolar electrode 109 being moved to the retracted position.

Specifically, in the case where the valve member 108 is a ball valve, a linkage mechanism can be provided between the ball valve and the driving part 106 (for example, a manual runner) to realize the linkage operation between the ball valve and the driving part 106. Thus, when the driving part 106 drives the unipolar electrode 109 to retract to the retracted position, the ball valve is closed accordingly; when the driving part 106 drives the unipolar electrode 109 to extend to the extended position, the ball valve opens accordingly. Preferably, the linkage mechanism provided between the ball valve and the manual runner may be a guide that couples the valve stem of the ball valve and the manual runner together. In this case, by pushing the manual wheel distally, while the electrode head is retracted proximally to the retracted position relative to the tubular member 107A and the shaft 107B as described above, the guide member drives the valve of the ball valve. The rod is used to close the ball valve accordingly, sealing the distal end of the cleaning part 111 to perform a cleaning operation on the monopolar electrode 109 in the cleaning part 111. In addition, by pulling back the manual runner to the proximal side, while the electrode head is extended to the extended position relative to the tubular member 107A and the shaft 107B as described above, the guide member drives the valve stem of the ball valve to The ball valve is opened accordingly, so that the inner cavity of the tubular member 107A is communicated with the external environment, and the control part 106 can control the monopolar electrode 109 to perform various surgical operations.

Alternatively, a separate ball valve operating part (such as a ball valve operating button) can also be provided, and the ball valve operating part can control the opening and closing of the ball valve in a mechanical or electrical control manner known to those skilled in the art. Thus, after the driving unit 106 drives the unipolar electrode 109 to retract to the retracted position, the operator closes the ball valve by operating the ball valve operating unit (for example, pressing the ball valve operating button) to perform a cleaning operation. In addition, after the cleaning operation is completed, the operator opens the ball valve by operating the ball valve operating portion (for example, pressing the ball valve operating button), and then drives the unipolar electrode 109 to extend to the extended position by the driving portion 106 to perform each operation.

As shown in FIG. 6B, when the monopolar electrode 109 is retracted into the cleaning part 111 and is in the retracted position, the butterfly valve 108A is closed, thereby sealing the distal end of the cleaning part 111. At this time, a cleaning operation may be performed on the monopolar electrode 109 in the cleaning part 111.

Specifically, in the case where the valve member is the butterfly valve 108A, the butterfly valve 108A can be driven to open and close in a manner similar to a ball valve as described above.
