A thoracoscopic rib wire saw guide and positioning set

Abstract

The invention discloses a thoracoscopic rib wire saw guiding and locating kit, which is composed of a wire saw guiding device and a wire saw locating device; a guiding tube in the wire saw guiding device is composed of a straight guiding tube section and an arc-shaped guiding tube section, wherein the front end of the straight guiding tube section is in smooth connection to the rear end of the arc-shaped guiding tube section; a movable push rod is inserted in the straight guiding tube section along an axial direction; an operating rod is arranged at the back of the push rod; an end of the operating rod runs through a through hole in the straight guiding tube section and extends out of the straight guiding tube section; the rear end of a volute spring is fixed with the front end of the push rod; a hook-shaped part is arranged on the left or right side face of the front end of the volute spring; and the wire saw locating device is composed of a locating tube and a locating handle. According to the thoracoscopic rib wire saw guiding and locating kit, a wire saw can be precisely and easily guided and located; and the rough and sharp wire saw is isolated from large blood vessels in an incision, lung and chest, so that precise rib resection can be conducted and the generation of side injury and a relatively large wound surface can be avoided.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a rib wire saw guiding and positioning set for thoracoscopic surgery. Background technique [0002] In medical practice, patients with benign or malignant rib tumors are often encountered, and the diseased ribs need to be removed at this time. At present, the popular method in China is: cut the skin and muscles of the chest first, and then remove the diseased ribs after exposing the ribs. Large, slow recovery in the later stage, long scars on the skin affect the appearance, and even cause long-term muscle dysfunction, resulting in inconvenient shoulder movements. [0003] The thoracoscopic technique, which has been gradually developed in recent years, performs surgical operations on intrathoracic lesions through small incisions or holes in the chest wall. While completing the operation with high quality, it does not cut off the chest wall muscles and does not stretch the ribs, thu...

AI Technical Summary

Problems solved by technology

[0008] In summary, the defects in the existing wire saw rib removal method are: 1. The rib cannot be removed accurately, and side damage and larger wounds are likely to occur. This is not only due to the difficulty in guiding and positioning the wire saw, but also It is also related to the direct contact with the wire saw to the incision, the lung and the great blood vessels in the chest; 2. The rib resection cannot be performed quickly and efficiently
