Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a roller surgical electrode. Background Technology

[0002] Roller surgical electrodes are electrosurgical instruments that use a rolling electrode head (similar to the continuous contact mode of industrial welding machine rollers) to maintain uniform contact pressure with tissues during surgery. They can be used for soft tissue dissection, resection, ablation, hemostasis, and drying in surgical procedures, and can be used in conjunction with endoscopes for minimally invasive surgery.

[0003] Existing roller surgical electrodes all have fixed rollers. If the location of the lesion tissue is inconsistent with the angle of the surgical electrode, or if the length of the surgical electrode cannot reach the lesion tissue, the doctor needs to manually move or change the position of the surgical electrode, or replace it with an electrode of a different angle or length. This may result in the electrode being applied to non-lesion tissue, causing accidental or excessive cutting, or it may fail to accurately locate the lesion tissue, leading to missed cutting, and other adverse effects. Moreover, the entire process results in a large surgical area, a long operation time, and significant harm to the patient. Utility Model Content

[0004] To address the issue of improving surgical efficiency, this application provides a roller surgical electrode.

[0005] The roller surgical electrode provided in this application adopts the following technical solution:

[0007] The handle has an injection port and a suction port at one end. The suction port is detachably connected to an external suction tube, and the injection port is detachably connected to an external injection tube.

[0008] The motor assembly is located on the other end of the handle. The motor assembly has an injection pipe and a suction pipe. The inlet of the suction pipe and the outlet of the injection pipe are both located at the same end of the handle and are both connected to the outside. The outlet of the suction pipe is connected to the suction port, and the inlet of the injection pipe is connected to the injection port.

[0009] Both the injection tube and the suction tube extend along the axis of the handle, with the injection tube surrounding the outer periphery of the suction tube. The suction tube has a first bend in its extension direction, and the injection tube has a second bend in its extension direction. An adjustment component is provided inside the handle to drive the suction tube to slide, thereby adjusting the length of the first bend extending beyond the second bend.

[0010] In one possible implementation, the regulating component includes:

[0011] A connecting block is fixedly mounted on the electrode assembly, and a cavity is opened inside the connecting block, with one end of the liquid suction pipe slidingly disposed in the cavity;

[0012] A connecting ring is fixedly installed on the outer wall of the suction pipe;

[0013] The return spring is connected at one end to the connecting ring and at the other end to the inner wall of the cavity;

[0014] The drive rod is connected to the connecting ring at one end and extends to the outside of the handle at the other end.

[0015] In one possible implementation, the drive lever includes:

[0016] The connecting part is fixedly connected to the connecting ring at one end;

[0017] The pressing part is fixedly connected to the end of the connecting part away from the connecting ring, and the pressing part is located outside the handle;

[0018] Both the connecting block and the handle are provided with limiting grooves to allow the connecting part to move.

[0019] In one possible implementation, the regulating component further includes:

[0020] Guide blocks are symmetrically arranged at both ends of the connecting ring;

[0021] Guide grooves are symmetrically opened on both ends of the connecting block, and the guide block and the guide groove slide together.

[0022] In one possible implementation, one end of the suction port is connected to a connecting tube, and the other end of the connecting tube is inserted into and connected to the suction pipe.

[0023] In one possible implementation, a limiting ring is provided on one end of the connecting tube that is inserted into the liquid suction tube.

[0024] In one possible implementation, the motor assembly includes a first electrode and a second electrode sleeved on the outer wall of the first electrode, a cable interface disposed inside the handle and connected at one end to an external cable, and roller electrodes electrically connected to the first electrode and the second electrode respectively. The other end of the cable interface is electrically connected to the first electrode and the second electrode respectively. A first bend is located on one end of the first electrode's start-up roller electrode, and a second bend is located on one end of the second electrode's start-up roller electrode.

[0025] In one possible implementation, the motor assembly further includes an identification module located within the handle, the identification module being electrically connected to the cable interface.

[0026] In one possible implementation, the motor assembly further includes a first insulating layer disposed on the inner wall of the first electrode and a second insulating layer disposed on the inner wall of the second electrode; both the first electrode and the second electrode are hollow tubular, a liquid injection channel is formed between the second insulating layer and the first electrode, and a liquid suction channel extends through the first insulating layer.

[0027] In one possible implementation, the motor assembly further includes a third insulating layer disposed on the outer wall of the first electrode and a fourth insulating layer disposed on the outer wall of the second electrode.

[0028] In summary, this application includes the following beneficial technical effects: When the roller surgical electrode is in working condition, the conductive medium in the injection device enters the injection channel through the external injection tube, injection interface, and injection channel inlet. The conductive medium is ionized into plasma and output to the injection channel outlet for surgical use. At this time, under the suction action of the suction device, excess liquid and impurities are output to the suction interface through the suction channel inlet and outlet, and then aspirated into the suction device through the external suction tube. The uniform contact pressure between the rolling electrode and the tissue, and the continuous release of high-frequency current during the roller rotation, generate a controllable temperature rise of 60-100℃. Under the thermal effect, the surface tissue forms a uniform coagulation layer, and the deep cells shrink due to dehydration, achieving a hemostatic effect. Simultaneously, under the action of the adjustment component, the first bent part of the first electrode is adjusted so that the first bent part slides outside the second bent part, thereby adjusting the angle of the roller electrode so that it can be used in some surgical electrodes that cannot reach the lesion tissue position, thereby reducing the situation of miscutting or overcutting non-lesion tissue, thereby improving the accurate positioning of lesion tissue, which is conducive to the smooth progress of the operation and improves the efficiency of the operation.

[0047] The specific working principle is as follows:

[0048] When the roller surgical electrode is in operation, the conductive medium in the injection device enters the injection channel through the external injection tube, injection interface 3, and the inlet of the injection channel. The conductive medium is ionized into plasma and output to the outlet of the injection channel for surgical use. At the same time, under the suction action of the suction device, excess liquid and impurities are output through the inlet and outlet of the suction channel to the suction interface 4, and then aspirated into the suction device through the external suction tube. The uniform contact pressure between the rolling electrode and the tissue, and the continuous release of high-frequency current during the rotation of the roller, generate a controllable temperature rise of 60-100℃. Under the thermal effect, a uniform coagulation layer is formed in the surface tissue, and the deep cells shrink due to dehydration, achieving a hemostatic effect. Simultaneously, under the action of the adjustment component, the first bent portion 7 of the first electrode 9 is adjusted so that the first bent portion 7 slides outside the second bent portion 8, thereby adjusting the angle of the roller electrode 12 so that it can be used in some surgical electrodes where the length cannot reach the lesion tissue, thereby reducing the situation of miscutting or overcutting non-lesion tissue, thereby improving the accurate positioning of lesion tissue, which is conducive to the smooth progress of the operation and improves the efficiency of the operation.

[0049] When it is necessary to replace the roller surgical electrode, there is no need to disconnect the external cable from the surgical equipment. Simply disconnect the external cable from the cable interface 11 and then connect the external cable to the cable interface 11 of another roller surgical electrode to complete the replacement. The operation is convenient and saves time.
