Abstract
The utility model provides an oral cavity expansion device, belonging to the technical field of medical instruments. The oral cavity expansion device comprises a casing pipe, a hand wheel, a screw A, a screw B, an arc-shaped support plate, an arc-shaped bottom plate, a limiting lever and arc-shaped expansion arms, and is characterized in that the middle part of the outer wall of the casing pipe is fixedly sleeved with the hand wheel, the upper end and the lower end of the casing pipe are internally in threaded connection with the screw A and the screw B which are opposite in thread direction respectively, the upper end of the screw A is fixedly connected with the right end of the arc-shaped support plate, the lower end of the screw B is fixedly connected with the right end of the arc-shaped bottom plate, the upper side of the left end of the arc-shaped bottom plate is vertically and fixedly provided with the limiting lever, the upper end of the limiting lever passes through a through hole adapted to the limiting lever in the upper side of the left end of the arc-shaped support plate, and then is connected with a limiting bulge, the middle parts of the rear end faces of the arc-shaped support plate and the arc-shaped bottom plate are vertically and fixedly provided with the mutually symmetric arc-shaped expansion arms, and the arc-shaped expansion arms are provided with rubber sleeves. The oral cavity expansion device has the advantages of being simple in structure and convenient to operate, and being capable of firmly supporting the oral cavity of a patient without shielding the visual field of medical personnel, thus being favorable for the smooth performing of a check or an operation.
Description
Technical field: this utility model belongs to the medical instruments technical field, specifically a kind of oral cavity dilator.
Background technology: at present, when doing mouth care or operation on oral cavity, need the patient to dehisce to greatest extent for a long time, because oral cavity muscle is easy to fatigue, so often need the oral cavity support clamp that support is expanded in patient's oral cavity.And existing oral cavity support clamp is because the pincers handle is positioned at the oral area dead ahead, to patient's operation on oral cavity the time, can cause medical personnel's the visual field and block, make medical personnel have to get around or avoid again the patient being treated behind the support clamp of oral cavity, like this troublesome poeration, waste time and energy inefficiency.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy to use, can not block the oral cavity dilator in the medical personnel visual field.
The purpose of this utility model is achieved in that this oral cavity dilator comprises sleeve pipe, handwheel, screw rod A, screw rod B, arc pallet, curved plate, gag lever post, arc expansion arm, sleeve outer wall middle part suit is being fixed handwheel, sleeve pipe is be threaded respectively hand of spiral opposite screw rod A and screw rod B of inside, two ends up and down, screw rod A upper end is fixedly linked with the arc pallet right-hand member, and screw rod B lower end and curved plate right-hand member are fixedly linked; Vertical fixing gag lever post above the curved plate left end, links to each other with spacing preiection behind the through hole that gag lever post upper end is passed above the arc pallet left end with it adapts; Arc pallet and curved plate rear end face middle part vertical fixing respectively the arc expansion arm that is provided with rubber sleeve above symmetrical.
During use, two arc expansion arm are placed the handwheel above the rotating casing outer wall behind the oral cavity, adjust making that upper and lower tooth is passive to be stung on two arc expansion arm after the distance between arc pallet and the curved plate, carry out examination of mouth or operation technique then and get final product.
Advantage of the present utility model: simple in structure, easy to operate, when the patient being carried out examination of mouth or operation, can firmly support the patient oral cavity, and can not block the medical personnel visual field, what be conducive to check or perform the operation carries out smoothly.
Description of drawings: Fig. 1 is structural representation of the present utility model.
The specific embodiment: describe in further detail below in conjunction with this utility model of Fig. 1: this oral cavity dilator comprises sleeve pipe 1, handwheel 2, screw rod A3, screw rod B4, arc pallet 5, curved plate 6, gag lever post 7, arc expansion arm 8, sleeve pipe 1 outer wall middle part suit is being fixed handwheel 2, sleeve pipe is inside, two ends be threaded respectively hand of spiral opposite screw rod A3 and screw rod B4 about in the of 1, screw rod A3 upper end is fixedly linked with arc pallet 5 right-hand members, and screw rod B4 lower end and curved plate 6 right-hand members are fixedly linked; Vertical fixing gag lever post 7 above curved plate 6 left ends, links to each other with spacing preiection 9 behind the through hole that gag lever post 7 upper ends are passed above arc pallet 5 left ends with it adapts; Arc pallet 5 and curved plate 6 rear end faces middle part vertical fixing respectively the arc expansion arm 8 that is provided with rubber sleeve 10 above symmetrical.
