Abstract
The utility model relates to a medical device, in particular to a controllable channel skin puncture trachea incision puncture needle. The medical device has a hollow needle body, a puncture handle is arranged at the rear end of the hollow needle body, a thread bar is arranged at the front section of the puncture handle, and a screwed cap and a rotating screw are arranged on the thread bar, the screwed cap can be left-right moveable along the thread bar and the rotating screw fixedly positions the position of the screwed cap. After using the tip to explore the vertical dimension from the epidermis to the airway cavity, using the screwed cap and the rotating screw to fix and position, and therefore, avoiding the danger of tracheoesophageal fistula caused by when the puncture needle damages the rear wall of the airway. The utility model is very safe and convenient for the new learner.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of tracheotomy puncture needle.
Background technology
In use there is certain defective in existing percutaneous puncture tracheotomy puncture needle: promptly cause the damage of trachea rear wall, esophagus because of misoperation easily, cause the generation of esophageal fistula.Especially for the abecedarian, the accident that causes because of misoperation happens occasionally.
Summary of the invention
The technical problem that this utility model need solve is: at existing percutaneous puncture tracheotomy puncture needle operation inconvenience, especially inconvenient localized problem, and a kind of controllability percutaneous puncture tracheotomy puncture needle is provided, make doctor's dynamics when carrying out trachea puncture grasp appropriate.
The technical scheme that this utility model adopted: it has a hollow needle body, the rear end of hollow needle body is the puncture handle, puncture handle leading portion is a threaded rod, and having on the threaded rod can be along the nut of threaded rod move left and right and the rotary screw that the position of nut is carried out stationary positioned.
The beneficial effects of the utility model: as long as this utility model with above structure is when operation after the vertical dimension with needle point spy and epidermis arrival air flue chamber, carry out stationary positioned with nut and rotary screw, thereby can avoid puncture needle damage air flue rear wall to cause the danger of tracheo esophageal fistula.Especially safe concerning the abecedarian, convenient.
