Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to an ablation electrode capable of self-controllable attraction. Background Art

[0002] At present, more and more open surgeries have been replaced by minimally invasive surgeries. Minimally invasive surgeries have many advantages, such as less surgical trauma, faster postoperative recovery, and beautiful abdominal incision scars. Therefore, minimally invasive surgery is an inevitable trend in the development of surgical methods in the future. In minimally invasive surgeries, there are many situations where human tissue needs to be cut and coagulated, and ablation electrodes are needed at this time. When ablation electrodes are used clinically, they need to enter the human body through a puncture device or other channels to perform electrocoagulation and electrocuting operations on human tissue.

[0003] An ablation electrode with self-controlled attraction in the current prior art. The ablation electrode currently used in clinical practice is usually controlled by a regulating valve or an electrocoagulation button to control the smoking channel, but it is self-controlled, and in the design of the entire handle, when the electrocoagulation function is performed, the electrocoagulation button is pressed, and a small amount of smoke generated is sucked into the channel and discharged. At the same time, the blood liquid carried by it will also seep out of the shell, causing the risk of infection to the operator. In addition, the blood liquid flows through the circuit board and causes a short circuit, resulting in automatic excitation. Secondly, it will continue to attract the gas in the cavity, reducing the operating field of view, which is very inconvenient for surgical operations. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the prior art that the smoke generated by the ablation electrode currently used in clinical practice during the coagulation operation cannot be effectively sucked out through the channel; secondly, when coagulation is not in progress, no smoke is generated but the air in the cavity continues to be extracted to reduce the air compression in the cavity and the small operating field; thirdly, the blood liquid brought out during the suction leaks out of the shell and causes infection to medical staff; fourthly, it makes the surgical operation very inconvenient. The utility model proposes an ablation electrode with self-controlled suction.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an ablation electrode with self-controlled attraction, including a steel tube main body, a coated electric hook head welded to the front end of the steel tube main body, a pressure-resistant heat shrink tube and an insulating plastic support are sheathed on the outside of the electric hook head, the steel tube main body is sheathed with a high-pressure resistant casing and the plastic support is fixed on the steel tube, and a section of the end is exposed to the outside, the end of the high-pressure resistant casing is wrapped with an injection molded rotating part, the outside of the steel tube main body is provided with a handle upper cover and a handle lower cover, the handle upper cover is installed with an electric cutting button and an electric coagulation button, the handle lower cover is provided with two springs, the springs A support body is provided above the spring, and the top of the support body supports the electrocoagulation button. A fixing piece is provided inside the support body, and the fixing piece is fixed on the handle lower cover. A silicone tube is provided between the handle upper cover and the handle lower cover, and one end of the silicone tube is connected to a first small joint, and a copper tube is sleeved in the first small joint. A second small joint is fixed to the other end of the silicone tube, and a suction steel pipe is sleeved in the second small joint. A valve sleeve is inserted at the other end of the suction steel pipe, and a negative pressure pipe is sleeved at the other end of the valve sleeve. A cable is provided on one side of the handle upper cover, and a PCB board is inlaid inside the handle upper cover and the handle lower cover.

[0006] Preferably, the silicone tube is placed on the clamping rib between the support body and the fixing part, the support body is provided with two through holes, the handle lower cover is provided with two guide columns, and the through holes cooperate with the guide columns, the spring is sleeved on the guide columns, and the support body moves up and down between them.

[0007] Preferably, one end of the silicone tube is connected to a first small joint, the first small joint is fixed in a slot of the lower cover of the handle, and the other end of the silicone tube is connected to a second small joint.

[0008] Preferably, the cable is welded on a PCB board, and the PCB board is provided with two pot pieces and a conductive spring piece.

[0009] Preferably, the electro-cutting button and the electro-coagulation button are slidably connected to the outer wall of the handle upper cover.

[0010] Preferably, a cable is fixedly connected to the outer wall of the PCB board, and a heat shrink tubing is sleeved on the outer wall of the PCB board.

[0011] Preferably, the handle upper cover and the handle lower cover are assembled into one piece by ultrasonic pressing, and the valve sleeve is tightly fitted with a valve switch.

[0014] Preferably, the copper tube is fixed in a slot of the lower cover of the handle, and the pot piece is fixed to the PCB board with a heat shrink tubing.

[0015] Compared with the prior art, the advantages and positive effects of the utility model are:

[0016] In the utility model, the coagulation function is stimulated by pressing the electrocoagulation button. The original slot on the fixing part and the rib on the support part squeeze the silicone tube mutually under the action of the spring to close it. The fixing part is fixed on the lower cover of the handle and remains motionless. When the electrocoagulation button is pressed, the support part below is driven to move downward. At this time, the degree of squeezing of the silicone tube is reduced, forming a passage, and the smoke is directly discharged from the passage. When the electrocoagulation button is pressed, both the electrocoagulation function and the suction function are realized. When the electrocoagulation function is not performed, the electrocoagulation button rebounds under the action of the spring, and the silicone tube is blocked again. Suction also stops, slowing down the air pressure filled in the patient's body in the early stage of the suction, and will not cause the process of narrowing the field of vision and filling the air pressure again. In addition, when coagulation is performed, the liquid brought by the suction process is directly extracted from the pipeline to avoid the risk of infecting the operator. The device uses the electrocoagulation button, and the silicone tube channel is opened when it is pressed. While realizing controllable smoking, it can also avoid the risk of infection of the operator by the liquid brought out during smoking, and can also slow down the pressure loss required in the patient's cavity.
