Technical field

The present invention relates to a kind of trachea bracket carrier, belong to technical field of medical instruments.

Background technology

Medical rack is widely used, is mainly used to strut narrow positions, stifled fistula or topical etc., and object makes tract unobstructed.

The anatomical structure of human body is: the opening of trachea ' C ' type cricoid cartilage is facing to esophagus.When doing Esophageal Stent, sometimes for preventing esophagus from corroding trachea, after first should placing a trachea bracket in trachea, place Esophageal Stent again, by analyzing like this, can find out: the consumption of trachea bracket relatively or should exceed the consumption of Esophageal Stent, but reality is: the consumption of the trachea bracket Esophageal Stent that is far from is so much.Reason is: do esophageal stenting, time does not limit substantially, doctor can tackle freely, and it is clinical in placing trachea bracket, when carrier transfer gantry enters trachea, will through glottis (vocal cords), at this moment patient body can locking glottis by the light of nature, add that existing carrier is the structure of pipe-in-pipe, overall diameter is little again, centre also has seal wire, have suffered the length of carrier more than 50 centimetres, in carrier, support is housed, under the spontaneous pressure reduction of human lung, can not ventilate substantially in carrier two ends, at this moment, the trachea of patient just cannot exchange substantially with extraneous air, that is patient is in " feeling suffocated " state, obviously, in this state, the time leaving doctor's complete operation for is very limited, usually require that doctor completed trachea bracket and places art in one minute, doctor is when carrying out this operation, action will be closely, otherwise, patient can whole body be strong dry dynamic by the light of nature, operation just may to withdraw from all apparatuses and failure fast, even also can cause the ill symptomses such as the shock of patient.Tracheal stent placing, in art, patient is in the state of " feeling suffocated ", the time leaving doctor's complete operation for is short, place accurately again, once the tolerance limit exceeding patient, other adverse consequences mismatched and attract that patient's instinct produces, the psychology that allowed the use of doctor to trachea bracket have therefore avoid, and seriously governs the application of trachea bracket.

Summary of the invention

The technical problem to be solved in the present invention: be to provide a kind of novel trachea bracket carrier, to solve under the spontaneous pressure reduction of human lung, existing carrier can not provide the access issues of intercommunication for patient airway and outside air, the liquid that simultaneously can prevent patient oral cavity from secreting again enters trachea, and then eliminates the time span restriction of tracheal stent placing operation process.

For achieving the above object, the present invention is achieved through the following technical solutions:

A kind of carrier of trachea bracket, comprise every liquid pipe assembly (1), support pressure draw assembly (4), its components (5), stop O type circle (2), locking member (3) etc., it is characterized in that: the support pressure draw (4-1) on described support pressure draw assembly (4), from the one end near support pressure draw handle (4-2) to the other end, its sidewall is distributed with passage, and its components (5) uses capillary stainless steel tube as central canal (5-3), central canal (5-3) is provided with stabilizer (5-2).

The present invention further improvement project is, on the support pressure draw (4-1), its sidewall is provided with some passages, the part of (5 ~ 20) centimeter length can be stayed not establish passage in the one end away from support pressure draw handle (4-2); Passage is the circular hole of diameter (0.5 ~ 2) millimeter or is circumferentially of a size of the profiled holes of (0.5 ~ 2) millimeter along tube wall; The passage that is staggeredly arranged relatively uniformly on the support pressure draw (4-1) sidewall.

The present invention further improvement project is, carrier its components (5) uses capillary stainless steel tube as central canal (5-3), pass through and be connected with: target seeker (5-1), stabilizer (5-2), inner core handle (5-5), inner core handle is connected with inner core bushing pipe (5-4).
