Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and more particularly to an ablation electrode device with flushing and suction functions. Background Art

[0002] Ablation electrode products are surgical equipment that need to be used in surgical operations. Their main functions are to cut, stop bleeding, flush, and aspirate tissues during surgery. The principle is that high-frequency current passes through the blade to produce a thermal effect, causing the blade to act on the tissue to produce eschar or burst, thereby achieving the function of coagulation or cutting.

[0003] Ablation electrodes are currently widely used in clinical minimally invasive abdominal surgery. Since minimally invasive surgery requires small incisions and requires the realization of electroresection, electrocoagulation, flushing, absorption and other functions in the abdominal cavity, the operation is difficult and requires the use of different instruments. During the use of the instrument, the equipment needs to be replaced to achieve the above functions, which has a certain impact on the difficulty of the operation. In order to solve this problem, many scientific researchers have devoted themselves to research and have produced certain results.

[0004] For example, the existing flushing and suction electrocoagulation cutter generally includes a shell, a control device, a tubular electrode and an electric hook connected to one end of the tubular electrode. The tail of the shell is provided with a T-tube, and the T-tube includes a horizontal tube and a vertical tube connected to the horizontal tube. One end of the horizontal tube is fixedly connected to the tubular electrode, and the other end of the horizontal tube is connected to a sealing nut. The control device includes tube I, tube II and tube III. The tubes I and II are connected to the tube III respectively, and the tube III is connected to the vertical tube. The side wall of the tube I is provided with a through hole I, and the side wall of the tube II is provided with a through hole II. The flushing and suction electrocoagulation cutter also includes a sliding valve I and a sliding valve II. Although this cutter also has functions such as electrocutting, electrocoagulation, flushing, and absorption, its control structures such as electrocutting, electrocoagulation, flushing, and absorption are shared, resulting in mutual constraints and inability for each part to operate independently, making the operation time-consuming and labor-intensive, and easy to slip and press the wrong button, affecting the efficiency of the work.

The second pipe 232 is provided on the side wall of the first pipe 231 and is connected to the first pipe 231; the knife tube 112 is connected to the first pipe 231, and the flushing pipe 21 is connected to the second pipe 232; the valve core 24 is movably connected to the first pipe 231 and controls the connection or disconnection between the first pipe 231 and the second pipe 232; the first elastic conduction mechanism 22 is also provided with a locking switch 25 for locking or releasing the position of the valve core 24 that moves in the first pipe 231.

[0046] In addition, one end of the valve core 24 is slidably installed in the first pipe 231, and the other end is a free end and is provided with a pressing portion 241 for pressing; one end of the valve core 24 installed in the first pipe 231 is provided with a channel structure 242, and the channel structure 242 is provided with a first port 243 and a second port 244 that are connected, the first port 243 is connected to the first pipe 231, and the second port 244 is connected to the second pipe 232. Generally, the pressing portion 241 can be made into a larger structure or a rubber structure can be provided on it, so that the force-bearing area of ​​the pressing portion 241 is increased to reduce the buffering force, facilitate the operator's pressing, and improve the comfort.

[0047] Among them, the locking switch 25 includes a locking part 251 and a connecting part 252 used to connect with the locking part 251, the connecting part 252 is installed on the valve core 24, and the locking part 251 is installed on the valve seat 23; the pressing part 241 is operated, the valve core 24 slides in the first pipe 231, and the locking part 251 is connected or disconnected from the connecting part 252; when the locking part 251 is connected to the connecting part 252, the first pipe 231 is connected to the second pipe 232; when the locking part 251 is disconnected from the connecting part 252, the first pipe 231 is disconnected from the second pipe 232. Specific working principle: when the operator presses the valve core 24, the valve core 24 slides into the first pipe 231, and when the channel structure 242 is connected to the second pipe 232, the locking part 251 in the locking switch 25 locks the connecting part 252, and the first pipe 231, the second pipe 232 and the channel structure 242 form a passage; when the operator presses the valve core 24 again, the locking switch 25 resets the valve core 24, the locking part 251 is disengaged from the connecting part 252, the port of the channel structure 242 fits with the inner wall of the first pipe 231, the pipe port of the second pipe 232 fits with the outer wall of the valve core 24, and the passage formed by the first pipe 231, the second pipe 232 and the channel structure 242 is disconnected.

[0048] Among them, the locking part 251 includes a shell 253, a buckle 254 connected to the connecting part 252, and a first spring 258. The buckle 254 is installed in the shell 253 and is slidably connected thereto. A guide groove 261 is provided on the shell 253, and a slider 259 is provided on the buckle 254. The slider 259 is installed in the guide groove 261. The first spring 258 is provided in the shell 253, and the first spring 258 is connected to the slider 259.

[0049] In addition, the buckle 254 includes a buckle body 255 and a first buckle branch 256 and a second buckle branch 257 for forming a scissor-type buckle structure with the connecting portion 252 , and the first buckle branch 256 and the second buckle branch 257 are installed at one end of the buckle body 255 . Specifically: when the operator presses the valve core 24, the valve core 24 pushes the buckle 254 to slide into the shell 253. After the buckle 254 slides a certain distance into the shell 253, the mouth of the shell 253 abuts against the first clamping branch 256 and the second clamping branch 257. When the valve core 24 continues to push the buckle 254 to slide into the shell 253, the shell 253 squeezes the first clamping branch 256 and the second clamping branch 257, so that the first clamping branch 256 and the second clamping branch 257 are increasingly fitted, thereby locking the connecting portion 252. When the operator presses the valve core 24 again, the slider 259 pushes the buckle 254 to slide out of the shell 253 under the action of the first spring 258. At the same time, the first clamping branch 256 and the second clamping branch 257 are separated from the shell 253, and the first clamping branch 256 and the second clamping branch 257 bounce off each other to release the connecting portion 252. It should be noted that the first clamping branch 256 and the second clamping branch 257 are both elastic structures, which are designed to ensure the smooth operation of clamping and loosening, and to prevent the rigid structure from breaking after multiple operations, thereby increasing its service life. Of course, these are preferred, and other similar structures are feasible as long as they can achieve the work goal.

[0050] The valve core 24 is also provided with a second spring 245 for quick reset. In this embodiment, when the valve core 24 is pressed, the valve core 24 slides into the valve seat 23, and under the action of the locking switch 25, the second spring 245 is in a squeezed state. When the operator presses the valve core 24 again, when the valve core 24 is reset, the second spring 245 in the squeezed state exerts a thrust on the valve core 24 in the reset direction, so that the reset can be faster.

[0051] In addition, a plurality of grooves 246 are provided on the outer peripheral surface of the valve core 24 in the first pipe 231, and a sealing ring is provided in the groove 246.

The trigger 323 is arranged at the free end of the trigger mechanism 321. Pressing the trigger 323 triggers the trigger mechanism 321 to move, causing the elastic conductive member 322 to move, thereby controlling the suction pipe 31 to be connected or disconnected with the knife tube 112.

The upper part of the control button 121 is an electrocutting button, and the lower part is an electrocoagulating button. By pressing the upper or lower button of the control button 121, the electrocutting and electrocoagulating functions are respectively switched on and off, thereby realizing the electrocutting and electrocoagulating functions. Of course, it should be noted that the upper part is an electrocutting button and the lower part is an electrocoagulating button.
