Description

Tracheal casing pipe exempts from tangential expander device

Technical field

This utility model relates to a kind of tracheal casing pipe and exempts from tangential expander device, is that a kind of tracheal casing pipe inserts the apparatus of performing the operation and relating to.

Background technology

Traditional tracheal intubation needs to be performed a surgical operation incisions by department of eye specialist, and cause operating difficulty greatly, surgical injury weight, complication is many, as hemorrhage, subcutaneous emphysema, pneumothorax and mediastinal emphesema, wound infection etc.And process need of holding a consultation delays the regular hour, often occasion a delay when rescuing emergency case, be unfavorable for patient's post-operative recovery.

Summary of the invention

The purpose of this utility model is to provide a kind of tracheal casing pipe and exempts from tangential expander device, solves the defect inserted tracheal casing pipe and need surgical incision, reaches by puncture expansion technique the object inserting tracheal casing pipe.

The purpose of this utility model realizes as follows: tracheal casing pipe exempts from tangential expander device, comprise dilator, separately there is a front end with the pricker of needle point, pricker leaves the taper gripping section that dilator expansion head-clamp is held, dilator has the expansion head mating with gripping section length, tapering and also can clamp pricker.

Dilator has by the hinged right clamp handle of thread spindle and left clamp handle, right clamp handle and left clamp handle are fixed with spring leaf respectively by screw, spring leaf front end in right clamp handle and left clamp handle is knotted together, the corresponding locking plate being arranged through serrated face and can locking together of the posterior medial of right clamp handle and left clamp handle, the front end of right clamp handle and left clamp handle is provided with expansion head, and right clamp handle is relative with the expansion head of left clamp handle forms cone-shaped inner hole and outline.

The middle part of pricker is cylindricality taper shank, the rear end of taper shank is the force head of expanding formation, the front end of pricker is taper needle point, the gripping section of taper is connected with between needle point and taper shank, the less formation annular boss of diameter of gripping section and needle point, taper shank junction, it is equal that head wall thickness expanded by the boss degree of depth and dilator.

During operation, fix trachea with hands, avoid pressure when puncturing to cause tracheal collapse, with the miter angle puncture obliquely of dilator clamping pricker, hold clamp handle after puncture and expansion head is opened, take out pricker, put into tracheal casing pipe, and complete follow-up operation.

This utility model is used for tracheal casing pipe and inserts operation, by the improvement of apparatus, thus changes operation method, makes complicated operation become simple, decreases complication, won rescue time, improve the success rate of rescue.

Detailed description of the invention

With reference to Fig. 1, Fig. 2, Fig. 3, this utility model comprises dilator and pricker, taper gripping sections 10 for dilator expansion 4 clamping, with needle point 9, pricker 8 are left in pricker 8 front end, and dilator has the expansion 4 of mate with gripping section 10 length, tapering and also can clamp pricker 8.

With reference to Fig. 2, dilator has by the hinged right clamp handle 1 of thread spindle and left clamp handle 5, right clamp handle 1 and left clamp handle 5 are fixed with spring leaf 2 respectively by screw 6, spring leaf 2 front end in right clamp handle 1 and left clamp handle 5 is knotted together, the corresponding locking plate 7 being arranged through serrated face and can locking together of the posterior medial of right clamp handle 1 and left clamp handle 5, the front end of right clamp handle 1 and left clamp handle 5 is provided with expansion 4, expansion 4 relative formation cone-shaped inner hole and an outline of right clamp handle 1 and left clamp handle 5.

With reference to Fig. 3, the middle part of pricker 8 is cylindricality taper shank 11, taper shank 11 excircle annular knurl process can increase frictional force, the rear end of taper shank 11 is the force 12 of expanding formation, the front end of pricker 8 is taper needle point 9, be connected with the gripping section 10 of taper between needle point 9 and taper shank 11, the less formation annular boss of diameter of gripping section 10 and needle point 9, taper shank 11 junction, it is equal that 4 wall thickness expanded by the boss degree of depth and dilator.

Dilator uses operating procedure: (1) patient body position: generally get dorsal position, shoulder underlay one pulvinulus, and head is swung back, and makes trachea close to skin, exposes obviously, and be beneficial to operation, assistant is seated at the patient crown, with fixing head, keeps positive meta.Routine disinfection, paving aseptic towel.(2) anaesthetize: adopt local anaesthesia.Between tracheal rings 2-4, with 1% lignocaine infiltration anesthesia, needle point 9 forward downward is to being about miter angle with horizontal line, and inserting needle limit, limit injecting narcotic, until enter tracheal strips.For stupor, the critical or patient that suffocates, if patient imperception also can anaesthetize.(3) otch: adopt transverse incision, cut skin in 2nd ~ 4 annulus trachealis places, otch is about 0.5-1.0cm.(4) patient stands on the left of patient, and left hand thumb and forefinger fix trachea, and makes trachea remain on center position, is unlikely to tracheal collapse when pricker 8 enters simultaneously.(5) right hand is held dilator and is moved forward into along the direction of inserting needle during anesthesia, and limit forward downward is exerted oneself limit rotating dilator, is convenient to dilator and enters.(6) after determining that trachea dilator enter trachea, left hand holds dilator and pricker 8 is also fixing, the right hand unclamps pricker 8, hold the right clamp handle of dilator 1 and left clamp handle 5 is tightened up gradually, dilator tracheal strips part is slowly expanded, when dilator is expanded to a certain degree, when pricker 8 loosens and can take out, assistant extracts pricker 8 out in time gently, continues slowly expansion until dilator expansion 4 easily can insert size is applicable to, with the tracheal casing pipe of Guan Rui.Right-hand man simultaneously forward downward firmly, ensures that dilator does not skid off trachea.(7) insert tracheal casing pipe: insert size and be applicable to, with the tracheal casing pipe of Guan Rui, according to the direction that the flexibility adjustment sleeve pipe of sleeve pipe enters, after inserting outer tube, take-off pipe stamen, puts into pipe immediately, exhaustion secretions, and checks with or without hemorrhage.(8) wound process: the belt in tracheal casing pipe lies in cervical region, breaks into fast knot to fixedly secure.Otch generally will not be sewed up, in order to avoid cause subcutaneous emphysema.Finally be padded between wound and sleeve pipe with one piece of opening gauze.
