Percutaneous tracheostomy device

Abstract

The invention provides a percutaneous tracheostomy device, comprising a lacerable catheter sheath, a trachea catheter and a puncture needle, wherein the lacerable catheter sheath is provided with a sheath catheter with a hollow cavity, and a sheath catheter joint fixedly connected with one end of the sheath catheter; the trachea catheter comprises a trachea cannula and enters the sheath catheter cavity of the lacerable catheter sheath via the sheath catheter joint, and parts of the trachea catheter are left out of the trachea catheter joint; the puncture needle head passes through the lacerable catheter sheath through the trachea cannula cavity to be exposed out of the lacerable catheter sheath; the tail of the puncture needle is left out of the trachea cannula; the puncture needle punctures through a catheter and introduces the trachea catheter and the lacerable catheter sheath to enter the catheter; the puncture needle is pulled out from the sheath catheter cavity, and the lacerable catheter sheath is torn; parts of the trachea catheter are left in the catheter, and parts of the trachea catheter are left out of the catheter.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a percutaneous tracheotomy device. Background technique [0002] The purpose of tracheotomy is (1) to relieve the obstruction of lower respiratory tract secretions caused by various reasons. (2) Relieve laryngeal obstruction caused by various reasons and improve breathing. (3) Respiratory weakness or respiratory arrest caused by various reasons requires artificial mechanical respiration. In certain head and neck operations, tracheotomy is required because oral intubation affects the operation. Clinically, tracheotomy often requires emergency treatment, and patients who need tracheotomy or tracheal intubation are not treated in time, which directly leads to the death of the patient. There are two types of tracheotomy: direct surgical incision and percutaneous tracheotomy. Various reports at home and abroad have the advantages of minimally invasive, less complication...

AI Technical Summary

Problems solved by technology

Its disadvantages are as follows: (1) The operation is relatively complicated. It may cause suffocation in patients who have not undergone tracheotomy and failed tracheal intubation.

(2) It is impossible to cut the trachea quickly

(3) The percutaneous incision methods mentioned above need to be performed with the assistance of an air microscope

(4) When inserting the endotracheal tube, because there is no protective effect of the catheter sheath, the trachea may be damaged, resulting in aspiration

(5) The endotracheal tube has only one air bag at the front end to prevent aspiration, and there is no air bag at the back end. If the thyroid gland covers the trachea, it may cause bleeding at the puncture site and require surgical exploration

(6) Imported consumables are expensive and difficult to promote in China
