Abstract

The invention discloses an improved plasma resectoscope comprising a cutting electrode and a loop electrode, wherein an insulation sleeve is arranged between the cutting electrode and the loop electrode; an endoscope mechanism is arranged at the outer side of the insulation sleeve; the cutting electrode comprises a base, a discharge point is arranged in the center of the base, and a metal ring is arranged at the outer side of the discharge point and is fixed on the base by virtue of a bracket; the loop electrode comprises a first electrode and a second electrode which are concentrically sleeved together, the second electrode is positioned at the inner side of the first electrode, and the length of the second electrode is less than that of the first electrode; and the endoscope mechanism comprises a seal housing, a camera is arranged at the bottom of the seal housing, a lens group is arranged above the camera, a light-permeable cover is arranged above the lens group, and a baffle is arranged at the edge of the light-permeable cover. The improved plasma resectoscope disclosed by the invention can overcome defects of the prior art, improve the operation efficiency, and reduce interference to visual operative field during operation.

Description

technical field [0001] The invention relates to a urological surgical instrument, in particular to an improved plasma resectoscope. Background technique [0002] Plasma resectoscopy is the most effective treatment for resection of prostate and bladder tumors. The biggest problem with conventional resectoscopes in the past was that it was easy to cause water intoxication in patients, and the hemostatic effect was poor. The surgeon was required to complete the operation within one hour. Compared with conventional resection of the prostate, plasma bipolar resection uses normal saline as the irrigation fluid, which avoids the occurrence of dilutional hyponatremia, and basically does not occur TURS. And there is less blood loss during the operation, and the postoperative recovery is faster. Chinese invention patent CN 102429723 B discloses a safe transurethral bladder tumor resection ring, which improves the safety of surgery. However, the existing resectoscope will cause inte...
