Abstract

The invention provides a diamond tooth distractor. The diamond tooth distractor is mainly structurally characterized by comprising a T-shaped handle, a left distracting bar, a right distracting bar, a screw with left-hand and right-hand threads and an opening adjustment hand wheel. The upper ends of the left and right distracting bars are connected to two ends of the lower portion of the T-shaped handle through hinges in diamond form, the left and right distracting bars are bent and conical, arc sides of the left and right distracting bars face to each other, the lower ends of the left and right distracting bars fit to form a tip, and the upper end of each of the left and right distracting bars is provided with a square hole. A square nut is disposed in each square hole. The upper ends of the left and right distracting bars are also provided with transverse through holes along the direction of threaded holes of the square nuts. Two ends of the screw with the left-hand and right-hand threads penetrate into the through holes and are screwed to the square nuts in the square holes. The opening adjustment hand wheel is disposed in the middle of the screw with the left-hand and right-hand threads. The diamond tooth distractor is simple in structure and convenient to operate, labor intensity can be greatly reduced for operators, teeth of patients can be quickly opened without damage, and the diamond tooth distractor is safe and practical.

Description

A kind of rhombus tooth dilator

Technical field

The present invention relates to technical field of medical instruments, specifically a kind of rhombus tooth dilator.

Background technology

Some patient symptom that happens suddenly; Such as epileptic, cerebral hemorrhage patient, drowned personnel or the like, gnathospasma during rescue, medical personnel are difficult to medicine is fed from the oral cavity or foreign body in the mouth is taken out; At this moment just need a kind of medical apparatus and instruments fast and safely the mandibular joint that the patient closes to be strutted; The deficiency that the dilator of prior art in use exists is a complex structure, not easy to operate, damages patient's tooth easily, 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 invention is the deficiency that solves prior art, and a kind of rhombus tooth dilator is provided.

Technical scheme of the present invention realizes by following mode; Its structure by T type handle, about strut bar, positive and negative threaded screw rod and aperture adjusting handle and form; Strut the bar upper end structure that assumes diamond in shape at the two ends of T type handle bottom that is connected through the hinge wherein, 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 and negative threaded screw rod two ends are through that the square nut in square hole is screwed among the cross through hole, are provided with the aperture adjusting handle in the middle of the positive and negative threaded screw rod.

Described rhombus tooth dilator struts about two outside the tip, lower end of bar and is with plastic bushing.

A kind of rhombus tooth dilator of the present invention has following outstanding beneficial effect: be simple in structure, and easy to operate, can greatly alleviate labor intensity of operating personnel, neither damage patient's tooth, can fast tooth be opened again, promptly safety is practical again.

Description of drawings

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

Labelling in the accompanying drawing is represented respectively: T type handle 1, aperture adjusting handle 2, positive and negative threaded screw rod 3, cross through hole 4, square nut 5, square hole 6, about strut bar 7, plastic sheath pipe box 8.Extension spring 13.

The specific embodiment

Below in conjunction with accompanying drawing rhombus tooth dilator of the present invention is done further explain.

A kind of rhombus tooth dilator of the present invention; Its structure by T type handle 1, about strut bar 5, positive and negative threaded screw rod 3 and aperture adjusting handle 2 and 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 nuts 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 and negative threaded screw rod 3 two ends are through that the square nut in square hole is screwed among the cross through hole 4, are provided with aperture adjusting handles 2 in the middle of the positive and negative threaded screw rod 3.

Described rhombus tooth dilator struts about two outside the tip, lower end of bar 7 and is with plastic bushing 8.

Embodiment

Method for using is following:

Hold T type handle, the patient is inserted upward between the lower teeth, with the intermediary aperture adjusting handle of the positive and negative threaded screw rod of thumb wheel in about two tips, lower end that strut bar; The aperture adjusting handle drives positive and negative threaded screw rod and rotates, positive and negative threaded screw rod two ends drive square nut with about strut bar separately, also patient's mandibular joint is strutted simultaneously; Medical personnel just can implement examination of mouth and rescue; Dilator is finished using, through disinfecting rotation aperture adjusting handle; Drive about two and strut bar gathering merging, supply use next time.

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

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

Claims

1. a rhombus tooth dilator is characterized in that, comprise T type handle, about strut bar, positive and negative threaded screw rod and handwheel; Strut the bar upper end structure that assumes diamond in shape at the two ends of T type handle bottom that is connected through the hinge wherein, 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 and negative threaded screw rod two ends are through that the square nut in square hole is screwed among the cross through hole, are provided with the aperture adjusting handle in the middle of the positive and negative threaded screw rod.

2. rhombus tooth dilator according to claim 1 is characterized in that, struts about two outside the tip, lower end of bar and is with plastic bushing.
