Description

Technical Field

[0001] This utility model relates to the field of radio frequency electrode cutting coagulation technology, specifically to a radio frequency electrode cutting coagulation device. Background Technology

[0002] Radiofrequency electrode coagulation cutter utilizes high-density radiofrequency current to generate a concentrated thermal effect on local biological tissue, causing tissue and tissue components to differentiate. Due to the small effective electrode area, sufficient heat can be generated locally in a short time to coagulate blood vessels to a certain depth, thereby achieving the surgical purpose of ablation and hemostasis in percutaneous endoscopic discectomy. Radiofrequency surgical electrosurgical unit is suitable for use in minimally invasive and delicate surgical departments such as plastic surgery, dermatology, dentistry, gynecology, LEEP surgery, ophthalmology, otolaryngology, spinal surgery, and neurosurgery.

[0003] In response to this, Chinese patent CN215129984U proposes an electrode cutting device based on radiofrequency ablation. This invention allows for the simultaneous treatment of soft tissue and endplates using the same tool, reducing the need for instrument changes. However, in the aforementioned patent, during the use of the radiofrequency electrode coagulation cutting knife, if it does not come into contact with the affected area to be treated, the radiofrequency electrode coagulation cutting knife is prone to damage to other areas of tissue due to improper operation, causing safety hazards during surgery. Therefore, a radiofrequency electrode coagulation cutting knife is needed. Utility Model Content

[0023] Please see Figure 1-6 This utility model provides a technical solution: a radio frequency electrode cutting coagulation device, including a control operation mechanism 1, a connecting cylinder 2 and a radio frequency cutting mechanism 3;

[0024] The control operation mechanism 1 includes a control handle 101. A first positioning groove 103 is provided in the middle of the control handle 101.

The inner wall of the positioning sleeve 107 is inserted and connected to the inner wall of the connecting cylinder 2.

[0025] The radio frequency (RF) cutting mechanism 3 includes a cutting base 301. A limiting groove 302 is formed in the middle of the cutting base 301. Sliding grooves 304 are formed on both sides of the inner wall of the limiting groove 302. A movable base 303 is slidably mounted on the inner wall of the limiting groove 302 through the sliding grooves 304. One end of the connecting cylinder 2 is fixedly connected to one side of the control handle 101, and the other end of the connecting cylinder 2 is fixedly connected to one side of the cutting base 301. One end of the positioning sleeve 107 passes through the cutting base 301 and is fixedly connected to the middle position of one side of the movable base 303. A scissor-type clamping frame 305 is rotatably mounted on one side of the inner wall of the movable base 303. RF cutting blades 306 are fixedly mounted on both sides of the inner wall of the scissor-type clamping frame 305. The combined length of the cutting base 301 and the scissor-type clamping frame 305 is equal to the length of the limiting groove 302.

[0026] An anti-slip pad 106 is fixedly provided on one side of the positioning snap 105.

[0027] Furthermore, a second positioning groove 108 is provided on one side of the inner wall of the movable frame 104, and a positioning rod 109 is slidably provided on one side of the inner wall of the second positioning groove 108. A positioning shaft 308 is fixedly provided at one end of the positioning rod 109. The outer wall of the positioning shaft 308 is inserted and connected to the middle position of the positioning sleeve 107. A fixing frame 311 is fixedly provided at one end of the outer wall of the positioning shaft 308 through the middle position of one side of the movable seat 303. Connecting rods 310 are rotatably provided on both sides of the inner wall of the fixing frame 311. Adjusting rods 309 are rotatably provided at one end of each of the two connecting rods 310. One end of each of the two adjusting rods 309 is rotatably connected to the two ends of the scissor-type clamping frame 305 respectively.

[0028] The two adjusting rods 309 are connected by a fixing rod 307 at the middle position. A return spring 312 is inserted at the middle position of the outer wall of the fixing rod 307, and fixing blocks 313 are fixed at both ends of the fixing rod 307.

[0029] The two sides of the return spring 312 are in contact with one side of each of the two adjusting rods 309.

[0030] Furthermore, an anti-slip sleeve 102 is fixedly provided on the outer wall of the control handle 101.

[0031] Working principle: When the radiofrequency electrode cutting coagulation device needs to be used, the hand-held control handle 101 is positioned by the connecting tube 2 to move the cutting seat 301 to the affected area. The operator slides and presses the positioning button 105 with his thumb, so that the positioning button 105 moves along the first positioning groove 103 to move the positioning sleeve 107. This causes the moving seat 303, which is fixed on one side of the positioning sleeve 107, to slide along the sliding groove 304 opened on the inner wall of the cutting seat 301. This causes the scissor-type clamp 305, which is rotatably connected to the inner wall of the moving seat 303, to move the radiofrequency cutting blade 306 to the outer wall of the cutting seat 301, which facilitates the operation of the radiofrequency cutting blade 306 and avoids the risk of accidental injury to other tissues during the movement. The scissor-type clamp 305 and the radiofrequency cutting blade 306 move under the protection of the cutting seat 301, which increases the safety performance of the radiofrequency electrode cutting coagulation device.

[0032] By hooking the positioning rod 109 with the index finger, the positioning rod 109 slides through the positioning groove 108, causing the positioning shaft 308 to slide. This causes the fixing frame 311, fixed on one side of the positioning shaft 308, to slide towards the side of the inner wall of the moving seat 303. This causes the connecting rods 310 on both sides of the inner wall of the fixing frame 311 to be driven by the linkage of the adjusting rod 309 to hinge the scissor-type clamping frame 305 inward. This causes the radiofrequency cutting blade 306, fixed on the inner wall of the scissor-type clamping frame 305, to clamp the tissue for coagulation-type cutting and ablation. Through the elastic deformation of the return spring 312, which is inserted through the outer wall of the fixing rod 307, the two ends of the return spring 312 press the two adjusting rods 309 respectively, causing the two adjusting rods 309 to move away from each other in their natural state. This prevents the scissor-type clamping frame 305 from naturally closing together, avoiding accidental injury and increasing the ease of use of the radiofrequency electrode cutting coagulation device.
