Abstract
An oral dilation support belongs to the technical field of medical appliances, and comprises an upper support arm, an upper tooth rest, a lower support arm, a lower tooth rest, a limit rod and a threaded sleeve. The oral dilation support is characterized in that the upper tooth rest and the lower tooth rest which are provided with tooth sockets on the outer walls are respectively fixed to the inner sides of the front ends of the upper support arm and the lower support arm, the inner walls of the rear ends are respectively perpendicularly connected with screws having opposite threads, the two screws are respectively connected to the insides of two ends of the threaded sleeve provided with a rotary plate on the outer wall of the middle, and the limit rod perpendicularly fixed to a bent part of the lower support arm penetrates through a through hole at the bent part of the upper support arm to be exposed outside the upper support arm, while the through hole matches with the limit rod. The oral dilation support is simple in structure and convenient in operation, can be used for firmly supporting an oral cavity of a patient in oral examination or surgery, and cannot block visions of medical staff, thereby facilitating smooth examination and surgery.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of oral cavity expansion eyelid retractor.
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 come patient's oral cavity is strutted by other apparatuses.Though and the oral cavity device for spreading that present stage uses can strut patient's oral cavity, block but in treatment or operation process, can cause medical personnel's the visual field, make operation of medical workers have to get around or avoid again the patient being treated behind the bracing or strutting arrangement of oral cavity, medical personnel's labor intensity is additionally increased, work efficiency obviously reduces, even error on the medical care precess appears, bring a lot of inconvenience to medical personnel.
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 expansion eyelid retractor in the medical personnel visual field.
The purpose of this utility model is achieved in that this oral cavity expansion eyelid retractor is by the upper support arm, last dens supporter, the lower support arm, following dens supporter, gag lever post, threaded sleeve is formed, upper support arm and lower support arm front end inboard are being fixed outer wall respectively and are being had alveolar dens supporter and the following dens supporter gone up, the rear end inwall vertically is connected with the opposite screw rod of hand of spiral respectively, two screw rods are threaded in the inside, threaded sleeve two ends that the outer wall middle part is provided with rotating disk respectively, and the gag lever post that is vertically fixed on lower support arm bending place passes the through hole that upper support arm bending place adapts with it and is exposed at upper support arm outside.
During use, dens supporter is placed oral cavity one side, rotate and to make the passive dens supporter of biting of tooth after rotating disk is adjusted distance between the upper and lower dens supporter, carry out examination of mouth or operation technique then.
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 help checking or performing the operation carries out smoothly.
Description of drawings
Accompanying drawing is a structure chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this oral cavity expansion eyelid retractor is made up of upper support arm 1, last dens supporter 2, lower support arm 3, following dens supporter 4, gag lever post 5, threaded sleeve 6, upper support arm 1 and lower support arm 3 front end inboards are being fixed outer wall respectively and are being had alveolar dens supporter 2 and the following dens supporter 4 gone up, and the rear end inwall vertically is connected with the opposite screw rod of hand of spiral respectively; Two screw rods are threaded in the inside, threaded sleeve 6 two ends that the outer wall middle part is provided with rotating disk 7 respectively, and the gag lever post 5 that is vertically fixed on lower support arm 3 bending places passes the through hole that upper support arm 1 bending place adapts with it and is exposed at upper support arm 1 outside.
