Problems solved by technology

[0007] Although the rationality and precision of the existing resectoscope electrodes have been relatively mature, there are still certain defects, mainly manifested in that the method of sliding back and forth for resection is not suitable for resection of oval patient tissues such as renal cysts. It is more unfavorable. Wh...

Abstract

The invention discloses a folding electrode resectoscope. The resectoscope comprises an endoscope, an operating handle and an electric cutter, the endoscope comprises an endoscope rod, and the operating handle detachably sleeves the endoscope rod; the electric cutter comprises a cutting electrode and a supporting rod connected with the cutting electrode, the cutting electrode is arranged on the end portion of the supporting rod, an electrode steering structure enabling the end portion of the supporting rod to rotate along an arc path is arranged on the supporting rod, and the electrode steering structure comprises a node structure enabling the end portion to rotate around an axis and a traction structure connected with the end portion and the operating handle; through operation on the operating handle connected with the traction structure, the supporting rod can be driven to rotate in a folding mode, the cutting electrode can conduct cutting along the radian of a sac wall, the risks ofsac wall bleeding, damage to a renal cortex, fat liquefaction and the like are reduced, the defect that an existing electrode resectoscope can only linearly conduct cutting forward and backward is remedied, operation is easy and convenient, and the operation efficiency is improved while wounds are reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a foldable electrode resectoscope for minimally invasive surgery. Background technique [0002] Renal cyst is the most common disease in urology, such as figure 1 As shown, renal cysts have the characteristics of an elliptical shape. Renal cyst decompression is the most effective method for the treatment of this disease, which can be divided into open surgery, laparoscopic surgery, and resectoscope resection surgery. Open surgery is basically out of use because of its greater damage to the patient's physiological structure and high risk; laparoscopic surgery is currently the mainstream surgery. The cyst wall is separated from the perirenal fat to expose part of the cyst wall, and then resected. The surgical trauma is relatively large, the operation time is relatively long, and the cost is high; resectoscope surgery also needs to separate the cyst wall to expose the c...
