Abstract

The utility model provides a rhombic mouth supporting opener. The rhombic mouth supporting opener mainly comprises a T-shaped handle, a leftwards and rightwards opening bar, a front and reverse screw rod and an opening degree adjusting hand wheel, wherein the upper end of the leftwards and rightwards opening bar is connected with two lower ends of the T-shaped handle through a hinge to be in a rhombic structure, the leftwards and rightwards opening bar is ceratoid, arc surfaces of the leftwards and rightwards opening bar are opposite, lower ends of the leftwards and rightwards opening bar are matched to form a tip portion, a square hole is mounted at the upper end of the leftwards and rightwards opening bar, a square nut is disposed in the middle of the square hole, a transverse through hole is mounted at the upper end of the leftwards and rightwards opening bar along the direction of a screw hole of the square nut, two ends of the front and reverse screw rod penetrate through the through hole to be in a screw connection with the square nut in the square hole, and the opening degree adjusting hand wheel is arranged in the middle of the front and reverse screw rod. The rhombic mouth supporting opener has the advantages that the structure is simple, the operation is convenient, the labor intensity of operators can be greatly reduced, teeth of a patient can not be damaged, the mouth of the patient can be rapidly opened, and the rhombic mouth supporting opener is safe and practical.

Description

A kind of rhombus tooth spreader

Technical field

This utility model relates to technical field of medical instruments, specifically a kind of rhombus tooth spreader.

Background technology

Some patient symptom that happens suddenly, such as epileptic, cerebral hemorrhage patient, drowned personnel etc., gnathospasma during rescue, medical personnel are difficult to medicine fed from the oral cavity or with foreign body in the mouth, at this moment the mandibular joint that just needs a kind of medical apparatus and instruments fast and safely the patient to be closed struts, the deficiency that the dilator of prior art in use exists is complex structure, not easy to operate, easily damages patient's tooth, does not also have good way to solve the problem of above-mentioned existence at present.

Summary of the invention

Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of rhombus tooth spreader is provided.

The technical solution of the utility model realizes in the following manner, its structure is by T-shaped handle, about strut bar, positive/negative thread leading screw and regulation handwheel form, strutting the bar upper end wherein is connected through the hinge at the two ends of T-shaped handle bottom, make it the integral body structure that assumes diamond in shape, about strut bar and be ceratoid, about to strut the cambered surface of bar relative, the lower end coincide into the tip, about strut bar the upper end have square hole, be provided with square nut in the middle of the square hole, about strut the upper end edge square nut of bar the screw direction also have cross through hole, positive/negative thread leading screw two ends are through that the square nut in square hole is screwed among the cross through hole, are provided with the regulation handwheel in the middle of the positive/negative thread leading screw.

Described rhombus tooth spreader, tip, the lower end overcoat that struts bar about two has plastic bushing.

A kind of rhombus tooth spreader of the present utility model has following outstanding beneficial effect: be simple in structure, and easy to operate, can greatly alleviate operator's labor intensity, neither damage patient's tooth, can fast tooth be opened again, namely safety is practical again.

Description of drawings

Accompanying drawing 1 is the structural representation of rhombus tooth spreader;

Labelling in the accompanying drawing represents respectively: T-shaped handle 1, regulation handwheel 2, positive/negative thread leading screw 3, cross through hole 4, square nut 5, square hole 6, about strut bar 7, plastic sheath pipe box 8.

The specific embodiment

Below in conjunction with accompanying drawing rhombus tooth spreader of the present utility model is described in further detail.

A kind of rhombus tooth spreader of the present utility model, its structure is by T-shaped handle 1, about strut bar 5, positive/negative thread leading screw 3 and regulation handwheel 2 form, strut the bar 7 upper ends structure that assumes diamond in shape at the two ends of T type handle 1 bottom that is connected through the hinge wherein, about strut bar 7 and be ceratoid, about to strut the cambered surface of bar 7 relative, the lower end coincide into the tip, about strut bar 7 the upper end have square hole 6, be provided with square nut 5 in the middle of the square hole 6, about strut the upper end edge square nut 5 of bar 7 the screw direction also have cross through hole 4, positive/negative thread leading screw 3 two ends are through that the square nut in square hole is screwed among the cross through hole 4, are provided with regulation handwheels 2 in the middle of the positive/negative thread leading screw 3.

Described rhombus tooth spreader, tip, the lower end overcoat that struts bar 7 about two has plastic bushing 8.

Embodiment

Using method is as follows:

Hold T-shaped handle, about two tips, lower end that strut bar are inserted between the upper lower teeth of patient, with the regulation handwheel in the middle of the thumb wheel positive/negative thread leading screw, the regulation handwheel drives the positive/negative thread leading screw and rotates, positive/negative thread leading screw two ends drive square nut with about strut bar separately, while also struts patient's mandibular joint, medical personnel just can implement examination of mouth and rescue, dilator is finished using, through disinfecting, rotation regulation handwheel drove about two and struts bar gathering merging, for next time.

T-shaped gag of the present utility model, processing and fabricating is very simple and convenient, uses stainless steel material to adopt by conventional process for machining processing and gets final product.

Except the disclosed technical characterictic of description of the present utility model, be the known technology of those skilled in the art.

Claims

1. rhombus tooth spreader, it is characterized in that, comprise T-shaped handle, about strut bar, positive/negative thread leading screw and regulation handwheel, strutting the bar upper end wherein is connected through the hinge at the two ends of T-shaped handle bottom, make it the integral body structure that assumes diamond in shape, about strut bar and be ceratoid, about to strut the cambered surface of bar relative, the lower end coincide into the tip, about strut bar the upper end have square hole, be provided with square nut in the middle of the square hole, about strut the upper end edge square nut of bar the screw direction also have cross through hole, positive/negative thread leading screw two ends are through that the square nut in square hole is screwed among the cross through hole, are provided with the regulation handwheel in the middle of the positive/negative thread leading screw.
