Simple chest closing binding belt for thoracotomy

Abstract

The invention relates to the technical field of medical apparatus and instruments, in particular to a simple chest closing binding belt for thoracotomy, which comprises a binding belt head and a flexible belt body which are connected with each other; the binding belt head is sequentially provided with a locking groove, a transition groove and a containing groove from one end far away from the flexible belt body to one end close to the flexible belt body; the locking groove comprises a long groove and a short groove which form a convex shape; the long groove is close to the flexible belt body; a plurality of evenly-distributed locking teeth are symmetrically arranged on the two sides of the flexible belt body; the flexible belt body firstly penetrates out of the long groove, so that the locking teeth on the two sides are clamped on the two short edges of the short groove respectively; then the flexible belt body penetrates into the transition groove and penetrates out of the containing groove; and therefore, the end of the flexible belt body is placed in the containing groove. According to the chest closing binding belt disclosed by the invention, after the flexible belt body penetrates through the long groove, the flexible belt body is directly matched and locked with the short groove through the locking teeth; the thickness of the binding belt head is greatly reduced; the redundant flexible belt body can be placed in the containing groove; the binding belt is neat and stable; the discomfort of a patient can be remarkably reduced through the chest closing binding belt; the cost is low; and economic burden of patients can be relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a simple chest-closing tie for open-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] Chi...

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
