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 mandibular joint 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, also do not 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 mandibular joint dilator is provided.
Technical scheme of the present invention realizes by following mode, its structure by handle, screw rod, support, strut arm and the herringbone connecting rod is formed, wherein; Support is a half elliptic, two ends through hinge with strut arm upper end and be connected, strutting arm, to become the ceratoid section be the groove shape; Two strut arm and are oppositely arranged and form two arc pyrometric cones, and triangular space is left in the centre of two arc pyrometric cones, has screw in the middle of the support; Screw rod is connected with screw through screw thread; The upper end of screw rod connects handle, and the lower end is connected with the herringbone connecting rod, and the herringbone connecting rod is positioned at two and struts among the intermediary triangular space of arm; The lower end of herringbone connecting rod struts arm through two on hinge respectively and connects, and is surrounded by plastic bushing or gum sleeve outside the tip, lower end that two strut arm.
Method for using is following:
Two tip, lower end insertion patients that strut arm are gone up between the lower teeth, and turning handle drives screw rod and rotates, and the intermediary screw threaded function of screw rod and support driving person font small end moves down; Herringbone connecting rod lower end will strut arm and outwards strut, and the while also struts patient's mandibular joint, implements examination of mouth and rescue to make things convenient for medical personnel; Dilator is finished using; Through disinfecting, rotary handle drives on the herringbone connecting rod and moves; Two strut arm gathering merging under the effect of upwards lifting of herringbone connecting rod, supply use next time.
A kind of mandibular joint 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 the oral cavity be opened not only safety but also practicality again.
Description of drawings
Labelling in the accompanying drawing is represented respectively: handle 1, screw rod 2, support 3, hinge 4, through hole 5, pin 6, herringbone connecting rod 7, strut arm 8, triangular space 9, plastic sheath pipe box 10, guiding draw runner 11, guide chute 12, extension spring 13.
The specific embodiment
Below in conjunction with accompanying drawing mandibular joint dilator of the present invention is done further explain.
A kind of mandibular joint dilator of the present invention, its structure by support 3, strut arm 8, handle 1, screw rod 2 and wedge shape awl 7 is formed, its medium-height trestle 3 is a half elliptic; Two ends through hinge 4 with strut arm 8 upper ends and be connected, strut arm 8 camber tapers, two strut arm 8 and are oppositely arranged and form two arc pyrometric cones; The middle upper portion of two arc pyrometric cones leaves triangular space 9, has screw in the middle of the support 3, and screw rod 2 is arranged among the screw; The upper end of screw rod 2 connects handle 1, and the lower end is connected with wedge shape awl 7, and wedge shape awl 7 is positioned at two and struts among the arm 8 intermediary triangular spaces 9; The centre of wedge shape awl 7 has 5, extension springs 13 of cross through hole and is through among the through hole 5, and the two ends of extension spring 13 strut arm 8 and 6 are connected through pinning with two respectively; Two strut arm 8 relative sides and have guide chute 12; The both sides of wedge shape awl 7 are provided with guiding draw runner 11, and guiding draw runner 11 is slidingly connected with guide chute 12, are surrounded by plastic bushing 10 or gum sleeve outside the tip, lower end that two strut arm 8.
Embodiment
Mandibular joint dilator 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.
Method for using is following:
Two tip, lower end insertion patients that strut arm are gone up between the lower teeth, and turning handle drives screw rod and rotates, and the intermediary screw threaded function driving of screw rod and support wedge shape is bored and moved down; The guiding draw runner of wedge shape awl both sides slides with the guide chute that struts on the arm, and the wedge shape awl will strut arm and strut, and the while also struts patient's mandibular joint; To make things convenient for medical personnel to implement examination of mouth and rescue, dilator is finished using, through disinfecting; Rotary handle; Drive on the wedge shape awl and move, two strut arm and under the effect of extension spring, draw merging in, confession use next time.
Except that the disclosed technical characterictic of description of the present invention, be the known technology of those skilled in the art.
