Trachea spreading forceps

Abstract

The invention relates to the technical field of medical appliances, in particular to trachea spreading forceps which comprise a left forceps body, a right forceps body and a self-locking mechanism, wherein the left forceps body comprises a left forceps handle, a left forceps neck and a left forceps head, the right forceps body comprises a right forceps handle, a right forceps neck and a right forceps head, the left forceps neck of the left forceps body is connected with the right forceps neck of the right forceps body by a hinged shaft, and the self-locking mechanism is arranged between the left forceps handle and the right forceps handle. The trachea spreading forceps are characterized in that the outer surfaces of the left forceps head and the right forceps head are cambered surfaces, the inner surfaces are smooth surfaces, and the left forceps head and the right forceps head are respectively provided with transverse teeth to enhance the friction between the trachea spreading forceps and tracheal rings so as to achieve the locating effect. By using the structure, the trachea spreading forceps in the invention have the advantages of novel structure, low operation risk, high success rate and the like, are convenient for operation, and can relieve pain of patients.

Problems solved by technology

[0002] At present, when doctors operate on patients with tracheotomy, they usually use a sharp knife to open the tracheal ring first, and then use ordinary vascular forceps to open the tracheal ring and insert the tracheal cannula. , right half pliers body and self-locking mechanism, left half pliers body is composed of left pliers handle, left pliers neck and left pliers head, right half pliers body is composed of right pliers handle, right pliers neck and right pliers head, left The neck of the pliers is connected with the neck of the right pliers via the hinge shaft. There is a self-locking mechanism between the handle of the left pliers and the handle of the right pliers. The inner walls of the left and right pliers heads are correspondingly equipped with horizontal teeth. The vascular forceps are used as the trachea spreader. The disadvantages are: first, because the inner wall of the forceps head is provided with horizontal teeth, when the tracheal cannula is inserted, it is easy to cut the air bag of the tracheal cannula, which is very common and very dangerous in tracheotomy. It cannot be inflated, and the trachea cannot be well closed. The blood from the incision flows into the trachea, which is easy to cause aspiration. At this time, the tracheal tube must be replaced, which increases the financial burden of the patient and the risk of surgery; if the amount of bleeding is too large, it may also cause suffocation, serious life-threatening

The second is that the outer surface of the forceps head is smooth and cannot fix the tracheal ring well. When the tracheal cannula is inserted, the vascular forceps will easily scratch the back wall of the trachea as the tracheal cannula enters the trachea, increasing the occurrence of tracheoesophageal fistula
