High-strength chest closing binding belt for thoracotomy

Abstract

The invention relates to the technical field of medical instruments, in particular to a high-strength chest closing binding belt for thoracotomy. The high-strength chest closing binding belt comprises a binding belt head and a flexible belt body, which are mutually connected, wherein the binding belt head is of a U-shaped structure and comprises a bottom plate and two side plates; at least one pair of first locking teeth is symmetrically arranged on the inner walls of the two side plates; and a plurality of second locking teeth matched with the first locking teeth are symmetrically arranged on two sides of the flexible belt body. According to the high-strength chest closing binding belt for the thoracotomy, the binding belt head is of the U-shaped structure, the first locking teeth are symmetrically arranged on the inner walls of the two side plates, the second locking teeth matched with the first locking teeth are symmetrically arranged on two sides of the flexible belt body, the flexible belt body is pulled out of the binding belt head, and the second locking teeth on two sides of the flexible belt body are matched with the first locking teeth on two side plates of the belt head to achieve locking. After the high-strength chest closing binding belt is used for closing and fixing the sternum, no obvious protrusion exists, the discomfort of a patient can be remarkably reduced, the price is low, and the economic burden of the patient can be greatly relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a high-strength chest-closing tie for thoracotomy. Background technique [0002] With the continuous improvement of medical technology, median thoracotomy still accounts for a relatively high proportion, and most heart, pericardium, and some mediastinal operations involve median thoracotomy. In the early stage of median thoracotomy, metal wires were often used for sternal closure. However, due to the thinner wires, it is very easy to cause cutting damage to the sternum, which will lead to serious complications such as poor sternal union and mediastinal infection, and increase postoperative mortality. Not only that, but it is also easy to cause a series of problems such as bone marrow cavity and tissue bleeding and rupture. Although the cable ties developed later can effectively avoid many adverse effects caused by thinner wires, there are still many problems. [0003] C...

Problems solved by technology

And from the patent document figure 1 It can be seen that the thickness of the fastening device is more than twice that of the flexible belt, and the fastening device is basically a cube structure. After the sternum is tied, no matter the left side ( figure 1 in the left side) facing forward, or above ( figure 1 The upper part of the breastbone) faces forward, protruding more from the sternum, rubbing against the surrounding tissues, which is easy to cause injury and infection, and because the fat tissue in front of the sternum is very thin, it will cause greater discomfort

[0004] In addition to the current use of cable ties will cause great discomfort to patients, the current use of cable ties is expensive, and the price of one can reach five to six thousand yuan. Generally, at least three cable ties are required to close the chest, which increases significantly. For patients with family difficulties, it is undoubtedly worse
