Description
Technical field
The present invention relates to technical field of medical instruments, specifically a kind of tooth spreader.
Background technology
Some patient symptom that happens suddenly, such as epileptic, cerebral hemorrhage patient, drowned personnel etc., tooth closes during rescue, medical personnel are difficult to medicine is fed from the oral cavity, or with foreign body in the mouth, at this moment the tooth 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 tooth spreader is provided.
Technical scheme of the present invention realizes in the following manner, its structure is by handle, screw rod, support, strutting arm and herringbone connecting rod forms, wherein, support is half elliptic, two ends by 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 the two arc pyrometric cones of composition, triangular space is left in the centre of two arc pyrometric cones, be provided with nut in the middle of the support, screw rod is connected with nut by screw thread, the upper end connecting handle of screw rod, the lower end is connected with the herringbone connecting rod, and the herringbone connecting rod is positioned at two and struts among the middle triangular space of arm, the lower end of herringbone connecting rod struts arm and is connected with two by hinge respectively, is 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, nut thread effect in the middle of screw rod and the support drives the herringbone small end and moves down, herringbone connecting rod lower end will strut arm and outwards strut, while also struts patient's tooth, 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 herringbone connecting rod and move, two strut arm draws merging under the effects that upwards lifts of herringbone connecting rod, for next.
A kind of tooth spreader 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, namely safety is practical again.
Description of drawings
Accompanying drawing 1 is the structural representation of tooth spreader;
Labelling in the accompanying drawing represents respectively: handle 1, screw rod 2, support 3, hinge 4, herringbone connecting rod 5, twisted axis 6, strut arm 7, triangular space 8, plastic sheath pipe box 9, nut 10.
The specific embodiment
Below in conjunction with accompanying drawing tooth spreader of the present invention is described in further detail.
A kind of tooth spreader of the present invention, its structure is by handle 1, screw rod 2, support 3, strut arm 7 and herringbone connecting rod 5 compositions, wherein, support 3 is half elliptic, two ends by hinge with strut arm 7 upper ends and be connected, strut 7 one-tenth ceratoids of arm, section is the groove shape, two strut, 7 are oppositely arranged the two arc pyrometric cones of composition, and triangular space 8 is left in the centre of two arc pyrometric cones, is provided with nuts 10 in the middle of the support 3, screw rod 2 is connected with nut 10 by screw thread, the upper end connecting handle 1 of screw rod 2, the lower end is connected with herringbone connecting rod 5, and herringbone connecting rod 5 is positioned among two triangular spaces 8 that strut in the middle of the arm 7, the lower end of herringbone connecting rod 5 struts arm 7 and is connected with two by hinge 6 respectively, is surrounded by plastic bushing 9 or gum sleeve outside the tip, lower end that two strut arm 7.
Embodiment
Tooth spreader of the present invention, processing and fabricating are very simple and convenient, handle, support, herringbone connecting rod and strut arm and use stainless steel materials to be processed into by punch forming process.
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, the fragrant disconnected effect of nut in the middle of screw rod and the support drives the herringbone small end and moves down, herringbone connecting rod lower end will strut arm and outwards strut, while also struts patient's tooth, to make things convenient for medical personnel to implement examination of mouth and medicine feed rescue, dilator is finished using, through disinfecting, rotary handle, the bolt and nut relativity drives on the herringbone connecting rod and moves, and two strut arm draws merging under the effect that upwards lifts of herringbone connecting rod, for next.
Except the disclosed technical characterictic of description of the present invention, be the known technology of those skilled in the art.
