A traction wire fixation device applied in single-port thoracoscopic minimally invasive lung surgery

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a traction suture fixing device applied in single-aperture thoracoscope minimally-invasive pulmonary surgery. The traction suture fixing device comprises a metal rod, a U-shaped metal ring with springs at intervals, and an extension tube, one end of the U-shaped metal ring is connected with one end of the metal rod through a first connecting member while the other end of the same is connected with the extensible tube through a second connecting member, the extensible tube is composed of more than two hollow tubes, heads and tail ends of adjacent plastic hollow tubes are sequentially connected in a sleeved manner, and a plastic hook is arranged at the tail end of each hollow tube. The traction suture fixing device is simple in structure, ingenious in conception, capable of straightening out a traction suture and adjusting direction and angle of the traction suture and convenient for exposing of surgical field, a cutting instrument is enabled to be capable of smoothly penetrating a target in pulmonary lobectomy under a single-aperture thoracoscope, and the surgery is simpler and easier to be popularized at the grassroot level so as to bring benefit to patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for multi-angle fixed traction wires applied in single-hole thoracoscopic minimally invasive lung surgery. 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. Among them, thoracoscopic lobectomy for the treatment of stage I and II non-small cell lung cancer and benign lung lesions has been affirmed for its safety and effectiveness, and has the advantages of less trauma, faster recovery, less postoperative pain, and less impact on the function of the shoulder joint. Thoracoscopy also has the same minimally invasive effect in the treatment of benign lung diseases. [0003] The approach of thoracoscopic lung surgery has undergone changes in the course of assisted incision thoracoscopic surgery, t...

Problems solved by technology

However, all the above-mentioned designs to solve the disadvantages of single-hole operation involve the handling of many traction lines. How to straighten out the relationship between these traction lines so that many traction lines will not be entangled with each other, and knotting has become the primary problem; how to adjust the traction The angle of the pulling direction of the wire also directly affects whether the surgical field is well exposed and whether the cutting instrument passes through the target smoothly.
