Problems solved by technology

However, laparoscopic renal cystic space-occupying surgery has certain risks: 1. Simple renal cysts are usually treated with decompression of renal cysts, that is, the cyst wall is opened, the cyst fluid is released, and then the cyst wall is resected.
A small number of renal cysts are accompanied by renal carcinoma, especially small renal carcinomas, which are difficult to find before operation; in addition, the diagnosis of simple renal cysts and cystic renal carcinomas is not clear
Therefore, letting the cyst fluid flow out will increase the risk of tumor cell implantation and metastasis
2. Cystic renal cell carcinoma, intratumoral cystic degeneration, and intracystic renal cell carcinoma usually undergo partial nephrectomy or radical nephrectomy. During the operation, there is a risk of cyst wall rupture, and cystic fluid outflow will cause tumor cell dissemination and metastasis
[0007] But about a kind of renal cystic space-occupying fluid collection system of the present invention, there is no report yet

Abstract

The invention relates to a renal cystic space-occupying cystic fluid collecting system, comprising an operation handle, a cystic fluid suction device, a cystic fluid collector, a runner, and an operation handle of an operation forceps, wherein the operation handle is composed of a main body handle and a movable handle; the cystic fluid suction device is composed of a regulating device, a pressuregauge, a pressure regulating valve, a cylinder 1, a cylinder 2 and a connecting device; and the operation forceps consist of an outer tube, an inner tube, a tube core, a tong head, a fixing shaft, a fixing nut, an outer cover and a collecting cover. The renal cystic space-occupying cystic fluid collecting system has the advantages that: only one TROCA channel needs to be occupied; the renal cysticspace-occupying cystic fluid collecting system can prevent the cystic fluid from flowing into retroperitoneal cavity, and limit the implantation and metastasis of tumor cells and the spread of infection, and can prevent the outflow of cystic fluid from renal cystic space-occupying lesions, thus reducing the time of surgical wound debridement, and alleviating the pain of patients and the workloadof medical staff.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a renal cystic space-occupying sac fluid collection system. Background technique [0002] Renal cystic masses include simple renal cysts, multilocular renal cysts, parapelvic cysts, polycystic kidneys, and cystic kidney cancer. It is a clinically common urological disease. The pathogenesis has not yet been fully elucidated and is a serious threat human health. [0003] At present, the main treatment for renal cystic space occupation is surgical treatment. The surgical methods are divided into open surgery, laparoscopic surgery, and renal cyst puncture and sclerosis. Open surgery has disadvantages such as large trauma, slow recovery, poor treatment effect, and difficult acceptance by patients, so it is not recommended clinically. Renal cyst puncture and sclerosis has the advantages of fast recovery, less trauma and easy operation, but its application range is limited. Laparosc...
