But, the guide wire groove on the existing elbow expansion forceps is curved, and the length of the curved guide wire groove is relatively long (more than 25 millimeters), and the bending state of the guide wire is uncertain, and it is very difficult for the operator to operate. It is difficult to quickly put the guide wire into the curved guide wire slot; in addition, the existing elbow dilator can only lock the head of the forceps like a vascular clamp, and when the elbow dilator stretches the trachea, the operator only needs to Can rely on the strength of the fingers to control the expansion of the elbow expansion forceps. This control action often affects the operator's concentration and may even affect the operation of the next operation

Embodiment approach
[0028] see figure 2 .A dilation forceps for tracheotomy operation, the forceps rod 6 is similar to the existing elbow dilation forceps, the forceps rod 6 is also composed of the pliers elbow 1 and the handle of the forceps, and the two forceps rods 6 are formed by pivot pins Rotatable connection. The handle of the pliers is a ring that can be inserted into the fingers at the end of the pliers rod 6. The inventive point of the present invention is that there is a mechanism 4 on the pliers rod 6 for controlling the opening degree of the pliers elbow 1. The mechanism 4 for controlling the opening degree of the pliers elbow 1 has There are many implementation modes, here is an example: the mechanism for controlling the opening degree of the pliers elbow 1 is composed of a left sleeve 300, a right sleeve 301, a limit bar 304 and a locking mechanism; the left sleeve 300 and the right sleeve 301 are respectively The looper is on the two clamp bars 6, and there is a spring 01 between...

The invention relates to the improvement of dilating forceps used in percutaneous dilatation tracheotomy. A dilating forceps used in tracheotomy comprises a nippling lever composed of elbow and handle, a mechanism used for controlling the opening width of the elbow, and thread guide groove on the elbow. Under the action of the mechanism for controlling the opening width of the elbow, formed tracheostoma will not be two large, which can not only prevent wound caused by over sized tracheostoma, but also is in favor of rapid formation of tracheostoma and shortens operation time.
Description
technical field [0001] This invention relates to instruments for surgical use, and more particularly to improvements in dilating forceps for use in percutaneous dilation tracheotomy. Background technique [0002] Percutaneous tracheostomy was developed in 1953, but because the instruments at that time were difficult to use and repeatedly punctured important structures around the trachea and caused death, few people applied it. Through the efforts of many scholars, new instruments were invented. Since 1985, percutaneous tracheotomy has been used in clinical practice. The new instruments have greatly reduced the complications and risks of tracheotomy. Since the instrument is a plurality of tissue dilators with different diameters, the anterior neck tissue is expanded sequentially from a small size, and it takes a long time to complete the expansion of the tracheal incision. In order to solve the problems existing in the prior art, in recent years, people have invented the elb...
