Abstract
The utility model relates to a novel mouth opener, which belongs to the field of an oral surgery operation appliance. The novel mouth opener comprises a U-shaped bracket with an upper tooth groove. A handle of the U-shaped bracket is matched and connected with an adjusting rod which can be adjusted from top to bottom and is provided with a lower tooth on the top end. A light source is arranged on the U-shaped bracket, wherein, the direction of the light source can be rotated. The upper end of the adjusting rod is provided with a tongue press rod which can be pulled from top to bottom, and can be disassembled and assembled. The novel mouth opener can be used for conveniently carrying out the mouth opening work in an oral cavity operation. The position of the light source is rotated, and a visual field in an operation is clear, which is favorable for enhancing operation quality.
Description
This utility model belongs to the oral surgery instrument field, the novel gag of particularly a kind of operation on oral cavity.
Present used gag in the operation on oral cavity generally just has alveolus, function singleness at the upper and lower end of U-shaped support.What have also has a spatula, but its spatula is fixed, can't take off, and has brought inconvenience to its use.And when carrying out operation on oral cavity, because gag is not with light source, must be by means of outer light source, and outer light source can not fully be injected the oral cavity, influences surgical field of view, thus may influence surgical effect.
The purpose of this utility model is to provide a kind of novel gag for the complete function that carries out oral cavity and tongue operation usefulness.
For achieving the above object, this utility model adopts following technical scheme: a kind of novel gag, comprise and be with alveolar U-shaped support, match and be connected, the light source of a usable rotational direction is installed on the U-shaped support but U-shaped support lever and the top of up-down adjustment are provided with down alveolar adjusting rod.
Lever is the tubular of band side opening, and the adjusting rod of band external tooth inserts wherein, cooperates with the externally threaded adjusting handle of being with at lever side opening place.
Adjusting rod upper end also is equipped with one and can pulls up and down and the spatula of dismounting, and a drainage tube is arranged on the spatula.
The light source lead penetrates from the lever bottom, passes from the U-shaped support top of hollow, and the light source rear portion has ball, and lampshade can rotate around ball.
The positive top dog of installing of lever is equipped with spring between top dog upper end and lever, on the lever of top dog lower end a through hole is arranged, and the lever back side is an entire body groove; In the leukorrhagia alveolar adjusting rod insertion groove of upper end, its with the lever contact surface on the groove that cooperates with top dog is arranged.
Adjusting rod upper end also is equipped with one and can pulls up and down and the spatula of dismounting, and a drainage tube is arranged on the spatula.
The light source lead penetrates from the lever bottom, passes from the U-shaped support top of hollow, and the light source rear portion has ball, and lampshade can rotate around ball.
Fig. 1 is this utility model structural representation;
Fig. 2 is the structural representation of embodiment 2.
This utility model can be used for oral cavity wall operation or tongue operation, when doing oral cavity wall operation, adjusts adjusting rod, makes spatula push down tongue; Doing tongue when operation, adjust adjusting rod, make the upper and lower alveolus upper and lower tooth that links closely, spatula can be pulled down and can dismantle.The light source that is loaded on the U-shaped support can multidirectionally rotate, and gets a clear view in the feasible operation, has avoided the limited shortcoming in the visual field of using external light source to bring.This utility model is easy to operate, only needs during use can effectively reach opening and press the tongue purpose by rotating handwheel or pushing top dog; Complete function, but not only opening, but also can press tongue, also can provide visual effect good built-in rotation light source, what help performing the operation carries out smoothly.
Further specify this utility model below by embodiment:
Embodiment 1, and a kind of novel gag comprises with the U-shaped support 2 of going up alveolus 1, and U type support lever 3 is the tubular of band side opening, and the adjusting rod 4 of band external tooth 15 inserts wherein, is with externally threaded adjusting handle 5 to cooperate with lever side opening place is fixed.Adjusting rod upper end is equipped with down that alveolus 20 and can be pulled up and down and the spatula 6 of dismounting, and spatula rear end two tacks are connected to both sides on the adjusting rod, are fixed with drainage tube 7 on it, can draw in the operation liquid in the oral cavity.By adjusting handle, adjusting rod can move up and down, the size thereby the adjusting gag is dehisced.U-shaped support hollow, power lead 8 therefrom passes, and is fixed with light source fixing feet 9 on U-shaped support top.10 is bulb, and 11 is lampshade, and ball 12 is connected with connecting rod 13, and connecting rod is fixed on the fixing feet by screw 14.Lampshade can rotate around ball, thereby makes light source direction adjustable, can obtain the optimal illumination effect in operation.
Embodiment 2, a kind of novel gag, and in the present embodiment, U-shaped support lever 3 is an after-opening groove shape, the lever front is hinged with a top dog 16, between top dog upper end and lever spring 17 is housed, and a through hole 18 is arranged on the lever of top dog lower end.Upper end leukorrhagia alveolar adjusting rod is in the tabular insertion lever groove, its with the lever contact surface on the groove 19 that cooperates with top dog is arranged, push on the top dog, lift the top dog lower end, adjusting rod can be in the lever groove up-down adjustment; Put down top dog, then its following end hook is pushed down the groove 19 on the adjusting rod, the secured adjusted bar, thus play opening and press the tongue effect.Other are with embodiment 1.
