Abstract
The invention provides a maxillary joint dilator, which consists of a support, dilation arms, a handle, a threaded rod and a wedge-shaped cone, wherein the support is in a semielliptical shape; two ends of the support are connected with the upper ends of the dilation arms by hinges; the two dilation arms are arranged oppositely to form a dual-arc triangular cone; a triangular space is reserved on the upper part of the middle of the dual-arc triangular cone; a screw hole is formed in the middle of the support; the threaded rod is arranged in the screw hole; the upper end of the threaded rod is connected with the handle, and the lower end of the threaded rod is connected with the wedge-shaped cone; the wedge-shaped cone is positioned in the triangular space in the middle of the two dilation arms; a traverse through hole is formed in the middle of the wedge-shaped cone; a tension spring passes through the through hole; two ends of the tension spring are connected with the two dilation arms respectively by pins; guiding chutes are formed on the sides of the two dilation arms, which are opposite; guiding sliding strips are arranged on two sides of the wedge-shaped cone and are in sliding connection with the guiding chutes; and plastic sleeves or rubber sleeves wrap tips of the lower ends of the two dilation arms.
Description
Technical field
The present invention relates to technical field of medical instruments, specifically a kind of maxillary joint dilator.
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 is fed from the oral cavity, or with foreign body in 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, and 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 to solve the deficiencies in the prior art, and a kind of maxillary joint dilator is provided.
technical scheme of the present invention realizes in the following manner, its structure is by support, strut arm, the hands handle, screw rod and wedge shape cone form, its medium-height trestle is half elliptic, two ends by hinge with strut the arm upper end and be connected, strut arm camber taper, two strut arm and are oppositely arranged the two arc pyrometric cones of composition, the middle upper portion of two arc pyrometric cones leaves triangular space, have screw in the middle of support, screw rod is arranged among screw, the upper end connecting handle of screw rod, the lower end is connected with the wedge shape cone, the wedge shape cone is positioned at two and struts among the middle triangular space of arm, the centre of wedge shape cone has cross through hole, an extension spring is through among through hole, the two ends of extension spring strut arm and are connected by pin with two respectively, two strut the relative side of arm and have guide chute, the both sides of wedge shape cone are provided with the guiding draw runner, guiding draw runner and guide chute are slidably connected, be surrounded by plastic bushing or gum sleeve outside the tip, lower end that two strut arm:
Using method is as follows:
Two tips, lower end that strut arm are inserted between the upper lower teeth of patient, turning handle drives bolt rotary, screw threaded function in the middle of screw rod and support drives the wedge shape cone and moves down, the guiding draw runner of wedge shape cone both sides slides with the guide chute that struts on arm, the wedge shape cone will strut arm and strut, while also struts patient's mandibular joint, to facilitate medical personnel to implement examination of mouth and rescue, dilator is finished using, through disinfecting, rotary handle drives on the wedge shape cone and moves, two strut arm draw merging under the effects of extension spring, for next time.
A kind of maxillary joint dilator of the present invention 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 the oral cavity be opened again not only safety but also practicality.
