Abstract

The invention discloses an anchor type bipolar electric cutting ring, and belongs to the field of urological surgical instruments. The ring comprises a Y-shaped power transmission rod and an anchor type cutting electrode, the cutting electrode comprises a T-shaped conductive rod and an arc-shaped electrode fixed to a bottom end of a T-shaped conductive rod, two ends of the arc-shaped electrode aretip ends, and the two ends of the upper portion of the T-shaped conductive rod are respectively connected to the Y-shaped power transmission rod through a connecting pipe. The arc surface of the arc-shaped electrode can perform the cutting of a large area of a bladder tumor, the end of the arc-shaped electrode can be used for achieving the whole piece cutting of the tumor, the anchor-shaped bipolar electric cutting ring has the advantages of a ring electrode and a needle electrode, the two ends can adjust the curvature and angle according to the needs so as to facilitate the cutting of tumorsin various parts of a bladder, frequent replacement of the electric cutting equipment during the operation is avoided, 'no dead angle and blind area' are achieved, and the ring shortens the operationtime, reduces the pain of patients, and provides a guarantee for accurate pathological staging.

Description

technical field [0001] The invention relates to an anchor type bipolar electric cutting ring, which belongs to the field of urological surgical instruments. Background technique [0002] The classic operation method for non-muscle-invasive bladder tumors is TURBT. During the operation, ordinary bipolar resection rings are usually used to resect the tumor in blocks and layers. This method is efficient and fast for large-volume tumors, but The cutting of the electrosurgical ring is carried out in the form of a surface. It is inconvenient to control the depth during the electrocution process, and it is easy to damage the tumor layer. As a result, the muscle layer may be missed in the pathological specimens sent for examination, thereby affecting the postoperative pathological staging. In addition, the cut tumor fragments will increase the risk of tumor dissemination, implantation and metastasis, which is also contrary to the tumor-free principle of tumor treatment. En bloc res...
