Abstract

The utility model discloses a mandible bracket, which comprises a base plate. Supports are correspondingly connected onto the base plate in a sliding manner, connecting rods are rotationally connected onto the two supports, carrying rods are mounted on the supporting rods, locking devices are respectively mounted among the supports and the base plate and among the supporting rods and the supports, the locking devices are locking screw rods, the carrying rods are mounted on the supporting rods in a sliding manner, locking bolts controlling extending heights of the carrying rods are mounted on the supporting rods, and elastic sponge layers are mounted at the ends of the carrying rods. The bracket can keep a mandible position of a patient in a lift-up state for a long period of time, avoids upper respiratory tract obstruction caused by drawing back of the mandible and posteria displacement of a tongue, needs no operation of two hands of medical staff using the bracket, and greatly reduces the labor intensity of the medical staff.

Description

A kind of chin rest

Technical field

This utility model belongs to anesthesia surgery and uses the utensil field, specifically is a kind of chin rest.

Background technology

During general anesthesia operation, owing to often causing the ccavum oropharygeum soft tissue tension to reduce to relax, the effect of medicine subsides, and lower jaw is retreated, move behind the root of the tongue, thereby upper respiratory tract completeness or imperfection take place block phenomenon, thereby bring out hypoventilation, even cause asphyxia, the patient breathes crisis because of anoxia or suffocates.Existing solution is to rely on doctor or nurse to adopt both hands to mention patient's angle of mandible trailing edge for a long time, utilize mandibular joint, suitably firmly forward, upwards mention with lower jaw, make incisor front or concordant on the lower incisor left-hand thread, avoid weighing down behind the tongue body, the shortcoming that this operational approach exists is the labor intensity that has strengthened medical personnel, and effect is undesirable.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of chin rest, can use this carriage to hold up patient's lower jaw when doing general anesthesia operation, makes it forward, upwards mentions, and has reduced medical personnel's labor intensity.

For solving the problems of the technologies described above, the chin rest of following structure is provided: it comprises the chassis, and correspondence slidely connects bearing on the chassis, respectively is rotatably connected to a support bar on two bearings, pressure pin is housed, between bearing and the chassis, between support bar and the bearing locking device is housed respectively on the support bar.

After adopting said structure, during as general anesthesia operation, this utility model can be placed on the operating-table, adjust bearing on the chassis the position and lock by locking device, make the end of two pressure pins be applicable to patient's lower jaw part, rotary supporting rod makes pressure pin mention patient's angle of mandible trailing edge, position by locking device lock support bar, this carriage can keep patient's lower jaw position to be in for a long time and mention state, avoided retreating because of lower jaw, weigh down the upper respiratory tract that causes behind the tongue body and block phenomenon, use this carriage with the hands to operate, greatly reduce medical personnel's labor intensity with regard to no longer needing medical personnel.

Described locking device is a tie down screw.

As improvement of the present utility model, described pressure pin is slidingly mounted on the support bar, and the clamping screw that the control pressure pin stretches out height is housed on the support bar, because the height at different patient's lower jaws position is different, the height that can adjust pressure pin is to be applicable to different patients.

As further improvement of the utility model, the elastic sponge layer is equipped with in the end of pressure pin, and the setting of spongy layer can increase patient's comfort level.

Description of drawings

Below in conjunction with accompanying drawing this utility model is further described:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 overlooks the sketch map of state for Fig. 1.

The specific embodiment

Chin rest as shown in drawings, it comprises chassis 1, correspondence slidely connects bearing 2 on the chassis 1, this is slidingly connected and is achieved in that bearing 2 is overlapped on the chassis 1 and can offers elongated slot 8 on the bearing 2 along the chassis upper surface slide, between bearing and the chassis locking device is housed, this locking device is a tie down screw 5, be that tie down screw 5 passes elongated slot 8 and is screwed onto on the chassis 1, after bearing 2 slides onto correct position, the relative position on bearing and chassis fixed by tie down screw 5.Respectively be rotatably connected to a support bar 3 on two bearings 2, between support bar 3 and the bearing 2 locking device is housed also, this locking device also is a tie down screw 5, above-mentioned being rotationally connected is achieved in that and is fixed with a sleeve 7 on the bearing 2, support bar 3 is sleeved in the sleeve 7 and can rotates in sleeve, after turning to correct position, by tie down screw 5 lock support bars 3 and telescopic relative position.Be slidingly fitted with pressure pin 4 on the support bar 3, pressure pin 4 comprises vertical section and picking-up section, vertically on the section sleeve pipe 9 is housed, sleeve pipe 9 is sleeved on the middle and upper part of support bar 3 to realize both being slidingly connected, the front end that holds up section is arcuation, the arcuation that two pressure pins 4 hold up section is oppositely arranged, so that hold up patient's lower jaw.Be bolted with control pressure pin 4 on the support bar 3 and stretch out clamping screw 6 highly, the elastic sponge layer also is equipped with in the end of the pressure pin 4 i.e. leading section of the section of picking-up.
