Description

Technical Field

[0001] This utility model relates to the field of minimally invasive resection technology, and in particular to a minimally invasive resection device for urological tumors. Background Technology

[0002] Minimally invasive techniques utilize advanced electronic, electrothermal, and optical equipment, replacing direct visual observation with electronic imaging and slender instruments with scalpels. The aim is to achieve observation, diagnosis, and treatment of lesions within the body with the smallest incision path and minimal tissue damage. These techniques are characterized by less bleeding, less postoperative pain, faster recovery, and minimal or no scarring.

The combination of sleeve 3, movable sleeve 4, collar support plate 14, thumb ring 15, I-shaped connecting plate 16, electrode blade 17, and torsion spring 22 increases the support force of the electrosurgical head when removing tumors. The surgeon can press and pinch the gap between the handle ring 7 and the thumb ring 15 to release the rebound of the torsion spring 22, making the annular electrode blade 20 extend and retract the corresponding distance to scrape the tumor more flexibly. The movable sleeve 4 slides smoothly on the surface of the guide rod 2, and the movable sleeve 4 drives the electrode blade 17 to be supported stably, reducing the difficulty of tumor surgical resection.

[0022] like Figure 1 , Figure 2 , Figure 3As shown, both ends of the I-shaped connecting piece 16 are provided with U-shaped mounting blocks 21. The surface of the U-shaped mounting block 21 is provided with mounting holes, and a rotating rod 23 is provided inside the mounting holes. A torsion spring 22 is sleeved on the surface of the rotating rod 23.
