Abstract

The utility model relates to the field of medical instrument for animals, in particular to a novel mouth opener which is formed by an inner frame and an outer frame. The inner frame is parallelly placed in the outer frame, two sides of the top of the inner frame are sleeved on two side walls of the outer frame, a screw is connected with and penetrates through the bottom edge of the outer frame, one end of the screw is hinged to the bottom edge of the inner frame, the other end of the screw is sleeved with a rotating handle, a beam a positioned at the top of the inner frame is in an arc shape with an opening upward, a beam b positioned at the top of the outer frame is in an arc shape with an opening downward, the beam a is wrapped with a snap-resistant plastic a, and the beam b (6) is wrapped with a snap-resistant plastic b. According to the novel mouth opener, an inlet part structure is suitable for an outline structure of the inside of an oral cavity, the sight range is increased, teeth and muscle tissues in the oral cavity are effectively protected simultaneously, and injury to the oral cavity is avoid when the mouth opener is used. The novel mouth opener is low in cost and simple to operate, has no harm to the oral cavity and is favorable for popularization and use.

Description

A kind of novel gag

Technical field

This utility model relates to a kind of animal specific medical instruments field, relates in particular to a kind of novel gag.

Background technology

Existing animal is by a spiral handle with gag, inner frame and outside framework are formed, during use inner frame and two top cross-bar of outside framework are put into cattle, with the spiral handle inner frame is separated with outside framework between the animal teeth such as sheep and dog, and then just the oral cavity is opened, the top cross-bar of its inner frame and outside framework all be arranged in parallel, because the upper jaw and the lower jaw of inside, oral cavity all are that certain radian is arranged, parallel frame roof crossbeam is put into and is understood obstruct the view within the oral cavity and influence therapeutic effect, existing gag all is to adopt metal material to make at intake section in addition, major injury both sides oral mucosa during opening, cause using the back animal and the stomatitis disease occurs, influence animal health.

The utility model content

This utility model is intended at the deficiency that exists in the background technology, and a kind of novel gag that proposes.

A kind of novel gag of the present utility model, be to be constituted by inner frame, outside framework and screw rod, the parallel outside framework inside that places of its inner frame, the both sides at its top are socketed on the two side of outside framework, the screw rod screw socket connects the base of running through outside framework, one end and inner frame base are hinged, other end cover is followed rotary handle, the crossbeam a at inner frame top is the circular arc that opening makes progress, the crossbeam b at outside framework top is the circular arc that Open Side Down, is wrapped in anti-plastic cement a, the crossbeam b6 of stinging at crossbeam a and is wrapped in the anti-plastic cement b that stings.

As further improvement of the utility model, described screw rod places the center on inner frame and outside framework base.

A kind of novel gag of the present utility model; the structure of intake section is designed to be more suitable for the contour construction of inside, oral cavity; increased visual line of sight, this product is designed to soft sebific duct parcel bar by the improvement of gag with the metal fixed bar; and be designed to the oral cavity arc; make the oral cavity opening fixing more abundant, easier oral cavity opening is observed and perfusion, and the oral cavity is not stimulated and not damaged; effectively protect oral cavity inner teeth gear and muscular tissue, solved the drawback of traditional gag.This utility model cost is low, and is simple to operate, and the oral cavity is not had injury, is beneficial to and promotes the use of.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with 1 pair of a kind of novel gag of the present utility model of accompanying drawing, be described further.

A kind of novel gag of the present utility model, be to be constituted by inner frame 1, outside framework 2 and screw rod 3, its inner frame 1 parallel outside framework 2 inside that place, the both sides at its top are socketed on the two side of outside framework 2, screw rod 3 screw sockets connect the base of running through outside framework 2, one end and inner frame 1 base are hinged, other end cover is followed rotary handle 4, and the crossbeam a5 at inner frame 1 top is the circular arc that opening makes progress, and is wrapped in the anti-plastic cement a7 that stings at crossbeam a5; The crossbeam b6 at outside framework 2 tops is the circular arc that Open Side Down, is wrapped in the anti-plastic cement b8 that stings at crossbeam b6.Described screw rod 3 places the center on inner frame 1 and outside framework 2 bases.

Claims

1. novel gag, be by inner frame (1), outside framework (2) and screw rod (3) constitute, it is characterized in that parallel outside framework (2) inside that places of inner frame (1), the both sides at its top are socketed on the two side of outside framework (2), screw rod (3) screw socket connects the base of running through outside framework (2), one end and inner frame (1) base is hinged, other end cover is rotary handle (4) then, the crossbeam a(5 at inner frame (1) top) circular arc that makes progress for opening, the crossbeam b(6 at outside framework (2) top) be the circular arc that Open Side Down, at crossbeam a(5) be wrapped in the anti-plastic cement a(7 that stings), crossbeam b(6) is wrapped in the anti-plastic cement b(8 that stings on).

2. a kind of novel gag as claimed in claim 1 is characterized in that described screw rod (3) places the center on inner frame (1) and outside framework (2) base.
