Abstract
An oral cavity expansion supporter belongs to the technical field of medical instruments. The oral cavity expansion supporter is formed by hinging a U-shaped upper jaw plate (1) with a U-shaped lower jaw plate (2) through a pin shaft (3) at the front end of the supporter. The oral cavity expansion supporter is characterized in that a handle II (4) and a handle II (5) which are mutually symmetrical are vertically fixed at the middle parts on the outer sides of the bottom ends of the U-shaped upper jaw plate (1) and the U-shaped lower jaw plate (2) respectively; a sleeve (8) with a hand wheel (7) on the outer wall is connected to a screw (6) vertically fixed on the inner wall of the handle II (5) through threads; and the upper end of the sleeve (8) pushes against the inner wall of the handle I (4). The oral cavity expansion supporter has a simple structure, is convenient to operate, can firmly support the oral cavity of a patient when the patient undergoes an oral examination or operation.

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 patient's mouth and bottleneck throat are checked, need patient independently to open oral area clinically, because oral cavity muscle is easy to fatigue, patient is difficult to adhere to for a long time in checking process, influences normal inspection.And the scarce influence inspection visual field is expanded in the oral cavity with common apparatus, increased medical worker's work difficulty.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and when carrying out examination of mouth to patient, can firmly support the patient oral cavity, and can not influence the oral cavity expansion eyelid retractor in the inspection visual field again.
The purpose of this utility model is achieved in that this oral cavity expansion eyelid retractor, and the front end bearing pin is hinged forms through it by " U " shape maxillary plate and " U " shape mandibular plate; It is characterized in that middle side part difference vertical fixing symmetrical handle I and handle II outside " U " shape maxillary plate and " U " shape mandibular plate bottom; Be vertically fixed on the outer wall that is being threaded on the screw rod above the handle II inwall and be provided with the sleeve of handwheel, the sleeve upper end withstands on the handle I inwall.
During use, put into the patient oral cavity after upper and lower jaw plate merged, rotate handwheel after making that upper and lower tooth is passive and biting upper and lower jaw plate, sleeve can strut upper and lower jaw plate, thereby expansion is supported in the oral cavity, and reaches the operation technique requirement.
The advantage of this utility model: simple in structure, easy and simple to handle, when the patient being carried out examination of mouth or operation; Can firmly support the patient oral cavity; And degrees of expansion can regulated at will, can not influence surgical field of view, and what help checking or performing the operation carries out smoothly.
