Problems solved by technology

[0003] In the existing technology, it is necessary to use the renal parenchyma forceps and tourniquet compression method under the laparoscope, the hemostatic effect is not accurate when the pressure of the renal parenchyma is small, and the renal parenchymal damage is easily caused when the pressure is high, the pressure adjustment is not fine enough, and During some operations, it may be because the artery is not completely blocked, or the artery is clamped loose, the venous reflux, or there is no surgical method to block the artery, etc., resulting in massive bleeding during the operation, causing serious damage to the patient's kidneys

Abstract

The invention provides a clamping device for kidney tumor resection, and relates to the field of partial nephrectomy. The clamping device comprises two clamping parts arranged in pairs, wherein each clamping part comprises two fixing plates and an arc-shaped clamping plate, the two fixing plates are symmetrically arranged on the outer side wall of the clamping plate, and the two fixing plates are symmetrically arranged on the outer side wall of the clamping plate; and an adjusting assembly for adjusting a gap between the two clamping parts is arranged between the two clamping parts, and clamping assemblies for secondarily clamping the kidney are arranged on the opposite side walls of the two clamping parts. According to the above technical scheme, the arranged clamping device can clamp the focus area of the kidney of a patient, the renal parenchyma part of the renal hilum can be avoided when the focus area of the kidney is clamped, and then blood supply of the clamped renal parenchyma part is effectively blocked; and moreover, the problem that after most of the focus area of the kidney is shielded, a doctor cannot conveniently cut or suture tumors in the focus area of the patient can be solved.

Description

technical field [0001] The invention relates to the field of partial nephrectomy, in particular to a clamping device used for renal tumor resection. Background technique [0002] Partial nephrectomy is the first choice for the treatment of early renal tumors, especially T1a renal tumors. During partial nephrectomy, renal blood flow should be blocked in order to clear the operative field and reduce intraoperative blood loss. Currently, the methods used to block renal blood flow include interventional embolization, renal pedicle block, renal artery trunk block, selective renal artery block, renal parenchymal forceps, and tourniquet compression. [0003] In the existing technology, it is necessary to use the renal parenchyma forceps and tourniquet compression method under the laparoscope, the hemostatic effect is not accurate when the pressure of the renal parenchyma is small, and the renal parenchymal damage is easily caused when the pressure is high, the pressure adjustment ...
