Pull-string lymph node biopsy forceps applied in single-port thoracoscopic radical resection of lung cancer

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to stay-cord type lymph gland biopsy forceps applied to single-hole thoracoscope radical operation. The stay-cord type lymph gland biopsy forceps consist of two parts, namely a stay-cord type lymph gland biopsy forceps body and a double-joint retractor, which are in magnetic jointing. The stay-cord type lymph gland biopsy forceps body comprises two short arms, two long arms and a spring, wherein jaws which form an oval when closed are arranged at the front ends of the two short arms. The double-joint retractor comprises two arms which are in parallel connection, each arm consists of a front part, a middle part and a rear part, and a protrusion is arranged at the front end of the front part of each arm. During use, the protrusions are in joggled connection with hollow hexahedrons on the stay-cord type lymph gland biopsy forceps body. The stay-cord type lymph gland biopsy forceps are easy to operate and are convenient and light, have the advantages that tail ends thereof can be free and variable in angle, the quantity of instruments moving in or out of the single hole is reduced, collision of multiple instruments is avoided, and lymph gland biopsy, access and thorough cleaning in single-hole thoracoscope pulmonary lobectomy are facilitated.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a drawstring-type lymph node biopsy forceps device used in single-port thoracoscopic radical resection of lung cancer. Background technique [0002] Thoracoscopic surgery was carried out in the early 1990s. After 20 years of development, the safety and effectiveness of thoracoscopic radical resection of lung cancer in the treatment of stage I and II non-small cell lung cancer have been affirmed. Mild postoperative pain and less impact on shoulder joint function. [0003] The surgical approach of thoracoscopic radical resection of lung cancer has undergone assisted incision thoracoscopic surgery, three holes, single operation hole (two holes), and single hole (single hole), and has become more and more minimally invasive and refined. At present, in a small number of thoracic surgery centers, thoracoscopic radical resection of lung cancer has been performed through a sin...

Problems solved by technology

[0005] However, due to the single-port thoracoscopic radical resection of lung cancer, the operation incision is fixed and unique, limited by the position and size of the incision, thoracoscope and various surgical instruments must enter and exit through the only hole together, and the angles of operating various instruments during the operation often collide with each other. However, it is not possible to use various instruments from different angles like thoracotomy or three-port thoracoscopic surgery. It is difficult to use conventional instruments to biopsy, obtain, and thoroughly clean lymph nodes in far-reaching positions such as upper mediastinum and subcarina

Therefore, the above disadvantages lead to increased difficulty of lymph node dissection in single-port thoracoscopic radical resection of lung cancer, which can only be done by experienced doctors in experienced thoracic surgery centers. How to solve these disadvantages will make single-port thoracoscopic radical resection of lung cancer Promoted to domestic grassroots units, better benefiting patients has become an urgent problem to be solved
