Stay bars capable of locking positions after stretching and retracting are arranged at the two ends of the long axis of an oval loop respectively, a protrusion capable of abutting against teeth is fastened at one end of the short axis of the oval loop, a handle rod capable of locking a position after stretching and retracting is arranged at the other end of the short axis and is provided with a bent end inside the oval loop, and a protrusion capable of abutting against the teeth is also fastened to the bent end. A clear view field is provided for an oral pharynx operation, and a tongue body, the side wall of the oral pharynx, the teeth and other tissue organs can be effectively protected.
Description
Technical field
The invention belongs to technical field of medical instruments, specifically a kind of oropharynx retractor.
Background technology
Doctor uses oropharynx retractor, can provide the visual field clearly for needing when patient carries out operation on oropharynx.The Chinese patent document that the patent No. number is ZL01252761.0 discloses one " oropharynx operation retractor ", but its structure still belongs to jaw type, the same with other forceps-shaped retractors, can not the histoorgan such as available protecting tongue body, lateral wall of oropharynx and tooth.
Summary of the invention
The object of the invention is to the shortcoming overcoming existing apparatus, a kind of oropharynx retractor is provided.
The technical solution adopted in the present invention is: a kind of oropharynx retractor, the strut of locking position after the major axis two ends place of an oval ring respectively establishes a flexible, the thrust of tooth can withstand in minor axis one end place fastening of oval ring, minor axis other end place establishes the handlebar of locking position after a flexible, handlebar has a crooked end in oval ring, also fastening one thrust that can withstand tooth on this crooked end.After described flexible the strut of locking position and the structure of handlebar known as the professionals, can be such as open a groove at the corresponding site of bar, in groove, one establishes and can be pressed downwards and the button skewback of automatically upspringing by spring supporting.
Beneficial effect of the present invention: can provide clearly while the visual field for operation on oropharynx, the histoorgans such as available protecting tongue body, lateral wall of oropharynx and tooth.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of embodiment.
Fig. 2 is the lock solid structure generalized section of strut in embodiment or handlebar.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As shown in Figure 1, 2, a kind of oropharynx retractor, a strut 2 is respectively established at the major axis two ends of one oval ring 1, the thrust 3 of tooth can be withstood in minor axis one end fastening, the minor axis other end establishes one handle bar 4, handlebar 4 has a crooked end 5 in oval ring 1, also fastening one thrust 6 that can withstand tooth on this crooked end 5.The corresponding site of strut 2 or handlebar 4 opens a groove 7, and in groove 7, one establishes to be supported by spring leaf 8 and can press downwards and the button skewback 9 of automatically upspringing.
Use of the present invention: overlap disposable soft protection sheath on the thrust that two can be blocked tooth, with hand-held handlebar, retractor is put into oral cavity, the extension of adjustment major axis two ends strut, and two thrusts are withstood upper and lower front tooth respectively.
