Incision retracting fixator applicable to single-pore thoracoscopic surgery

Abstract

The invention relates to an incision retracting fixator applicable to single-pore thoracoscopic surgery. The incision retracting fixator has two kinds of structures A and B and comprises an elastic pipeline, an oval elastic pipeline is embedded in the circular elastic pipeline, the oval pipeline and the elastic pipeline are integrated, and two ends of an acute point of the oval elastic pipeline embedded in the circular elastic pipeline are closely embedded with circular elastic the pipeline. The circular elastic pipeline is an elastic waist-drum-shaped cylinder, and the oval elastic pipeline is embedded in the pipeline and is arranged in the middle to form three channels or at the edge to form two channels. During surgical operation, a thoracoscope and an operation instrument can pass the same incision, and compared with conventional thoracoscopic surgery, the single-pore thoracoscopic surgery performed with the incision retracting fixator has the advantages that two incisions can be reduced and surgical operation is more minimally invasive and has the remarkable advantages in reducing postoperative incision pain and paresthesia of the thoracic wall and accelerating postoperative recovery and the like, and for those patients with poor cardio-pulmonary function, operation risk is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and is an incision retractor fixer especially suitable for single-hole thoracoscopic surgery. Background technique [0002] Minimally invasive surgery is the direction of surgical development, and its purpose is to reduce pain and improve the quality of life of patients. The traditional 3-incision video-assisted thoracoscopy (VATS) has reached a consensus on the therapeutic effect of thoracic diseases, and has become an essential technique for thoracic surgeons. At present, the rapid progress in technology has made thoracic surgery more "minimally invasive" and postoperative recovery more "fast". Single-port thoracoscopic surgery is undoubtedly a more "minimally invasive" exploration and a new direction of minimally invasive thoracic surgery. Single-port thoracoscopic surgery refers to the use of only one incision of about 3.0-4.0 cm, and the observation mirror and surgical instrume...

Problems solved by technology

Single-port thoracoscopic surgery itself also has certain disadvantages. The existing thoracic-related equipment is not suitable for single-port thoracoscopic operation: one operation hole, all operating instruments enter and exit through this port, there is mutual interference between instruments, and there is often a After the device goes in, other devices cannot enter or move; the smoke generated by the electric knife or electrocoagulation cannot be discharged smoothly (because the suction device can no longer be put in during the operation, and the operation can only be suspended to discharge the smoke); in addition, the chest cavity The instrument itself is relatively hard, and the diameter of the instrument is large. During the operation, it repeatedly enters and exits from the intercostal space, which aggravates the damage to the intercostal nerve, resulting in aggravated and long-lasting postoperative discomfort.
