Rib fretsaw locator for thoracoscope

Abstract

The invention discloses a rib fretsaw locator for thoracoscope. A locating pipe is formed by two locating branch pipes having completely same structure and size, the two locating branch pipes are arranged together side by side closely, and a fretsaw passes through the center hole in each locating branch pipe; the locating branch pipes are hard pipes, and are formed by straight pipe sections and arc pipe sections, the front end of each straight pipe section is smoothly connected with the rear end of the respective arc pipe section, and bent directions of the two locating branch pipes are consistent; and the handle structure is arranged at the rear part of the straight pipe section of each locating branch pipe. The fretsaw can run through the rib fretsaw locator, and the fretsaw can be separated from a wound incision and great vessels in lungs and chest, so that the incision and great vessels in lungs and chest can be radically prevented from being injured by a rough and sharp fretsaw; and the front end of the arc pipe sections can be closely contacted with the surface of a rib to be cut off, so that the fretsaw can be accurately located, severe shaking of the fretsaw can be avoided when a rib is cut off, smooth operation and cutting accuracy of an operation can be guaranteed, and side injury can be avoided.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a thoracoscopic rib wire saw positioner. 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, thus significantly...

AI Technical Summary

Problems solved by technology

However, due to the lack of effective thoracoscopic rib resection instruments, it is difficult to carry out thoracoscopic rib resection.

At present, foreign countries also have the technology of removing ribs under thoracoscopic conditions. The specific implementation methods are as follows: 1. Rib scissors are used under thoracoscopy, which are similar to scissors. , the rib incision is not neat; 2. Under the thoracoscope, the lengthened dental drill is used to cut off the ribs that have lost normal function. The dental drill is not easy to fix, and it is easy to slide; 3. Use a wire saw under the thoracoscope. This method directly incisions on the s
