Dual-cavity capsule dilator with electrocoagulation function

Abstract

The invention relates to a dilator, in particular to a dual-cavity capsule dilator with an electrocoagulation function, and belongs to the technical field of medical instruments. According to the technical scheme, the dual-cavity capsule dilator with the electrocoagulation function comprises a dilation capsule connecting body, a dilatation capsule body located at the dilatation capsule connectingbody and an electrocoagulation body which can be used for hemostasis and is adaptably connected with the dilation capsule connecting body, the electrocoagulation body comprises an electrocoagulation head and an electrocoagulation power supply connector adaptably connected with the electrocoagulation head, and the electrocoagulation head is located outside the head ends of the dilatation capsule body and the dilation capsule connecting body. The dual-cavity capsule dilator with the electrocoagulation function is compact in structure, convenient to use, safe and reliable, the narrow parts of trachea and bronchi can be effectively dilated, hemostasis operation can be achieved in the dilation process, required continuous dilation is achieved, the operation risk and difficulty are reduced, andthe efficiency of dilation operation is improved.

Description

Technical field [0001] The invention relates to a dilator, in particular a double-lumen balloon dilator with electrocoagulation, and belongs to the technical field of medical devices. Background technique [0002] Tracheal stenosis is a common clinical disease. In the operation of respiratory diseases, tracheal stenosis accounts for a considerable number of patients. There are many causes, such as scars leading to tracheal stenosis, and various benign tracheal stenosis is the most common. Benign tracheal stenosis is a common disease in clinic. It has many causes. In my country, tuberculous tracheal stenosis ranks first among all benign tracheal stenosis. Clinically, the methods used in the treatment of tuberculous tracheal stenosis include: sleeve resection of the narrowed trachea, YAG laser cutting of the narrowed section, and metal stent implantation to reconstruct the trachea. However, these treatment methods have different degrees of risk, difficulty in treatment, and high c...

AI Technical Summary

Problems solved by technology

Tracheal balloon dilation is completely blocked ventilation, in order to ensure the ventilation of the patient's lungs, each expansion time can generally be controlled within more than 10 seconds, and the front end of the currently used balloon dilator inserted into the trachea is closed , during treatment, the balloon dilator is introduced into the narrowed part of the trachea, and then high-pressure normal saline is pumped in to expand the balloon. At this time, the expanded balloon will completely block the trachea and the patient is hypoxic, causing mechanical asphyxia of the patient. There are great risks and inoperability

In addition, the placement of stents can stimulate the proliferation of granulation tissue, etc., and it is generally not suitable for tracheal stenosis caused by benign diseases, and the removal of removable stents has the problem of difficult operation

[0004] In addition, when the tracheal stenosis is dilated, the stenosis will cause bleeding. At present, after the stenosis is dilated and bleeding occurs, the dilation is stopped to stop the bleeding, and the dilation is performed after hemostasis. Therefore, it is necessary to repeat the exchange of dilation and hemostasis. Operation, low expansion efficiency, complex operation, difficult to achieve real continuous expansion operation
