Problems solved by technology
[0004] However, due to the fixed and unique operating incision of single-port thoracoscopic lung lobe surgery, limited by the position and size of the incision, thoracoscope and various surgical instruments must enter and exit through a single hole. , you can’t use various instruments from different angles like thoracotomy or three-port thoracoscopic surgery; again, the viewing angle is limited, and thoracotomy or three-port thoracoscopic surgery can pull the lung lobes in all directions to expose the parts that need to be understood and structure, but the single-port thoracoscopic operation cannot be so arbitrary
The above drawbacks lead to the increased difficulty of single-port thoracoscopic minimally invasive surgery, which can only be performed by experienced doctors in experienced thoracic surgery centers. How to solve these drawbacks will push single-port thoracoscopic minimally invasive surgery to Domestic grassroots units, better benefiting patients has become an urgent problem to be solved

Embodiment Construction
[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0016] Such as figure 1 As shown, the device is composed of two parts: the main body 1 of the drawstring lung traction forceps and the double-joint opener 2. The two parts are magnetically docked, fitted together, and sent into the chest cavity. 2, release the drawstring-type lung traction forceps body 1, so that it is free, and finally pull it out of the chest cavity by the stay rope 8 provided in the drawstring-type lung traction forceps body 1.
[0017] The main body 1 of the drawstring type lung traction forceps is composed of two mutually symmetrical forceps bodies that are hinged and connected together through the pin shaft 4. The front end of the forceps body is the forceps head 3, which is a right-angled triangle, and its surface is provided with concave and convex textures to increase friction direct contact with the surface of the l...

The invention belongs to the technical field of medical instruments and particularly relates to a pull cord type lung traction forceps applied to single-port thoracoscopic lobectomy. The pull cord type lung traction forceps comprise a forceps body and a bi-articular opener-closer which are magnetically connected to each other. The pull cord type lung traction forceps have the advantages that the forceps are simple to operate, handy and light in weight, the tail end of the forceps is free, fewer single-port access instruments can be used, crash of the instruments is avoided, lung lobes can be pulled in various directions to expose corresponding parts and structures, and surgical field exposure and operations in single-port thoracoscopic lobectomy are facilitated.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a drawstring-type lung traction forceps used in single-port thoracoscopic lobectomy. Background technique [0002] Thoracoscopic surgery was carried out in the early 1990s. After 20 years of development, it has been widely used in the diagnosis and surgical treatment of various diseases in thoracic surgery. The safety and effectiveness of thoracoscopic lobectomy for stage I and II non-small cell lung cancer and benign lung lesions have been affirmed, and it has the advantages of less trauma, faster recovery, less postoperative pain, and less impact on shoulder joint function. [0003] The surgical approach of thoracoscopic lobectomy has undergone assisted incision thoracoscopic surgery, three holes, single operation port (two ports), and single port (only port). Because there is a conversion from a three-dimensional field of view to a two-dimensional field of view in tho...
