The invention adopts the technical scheme that the soft palate traction device for the Davis mouth gag comprises a compression spring, a traction plate, a fixing block, a traction plate positioning rod and a cover board, wherein the upper part of the fixing block is provided with a clamping groove installed on the Davis mouth gag; a flat slot for placing the traction plate is formed below the clamping groove; the lower part of the fixing block is provided with a cavity body; the center of the top surface of the cavity body is provided with a tooth hole communicated with the bottom surface of the flat slot; the traction plate is arranged in the flat slot of the fixing block; the traction plate positioning rod and the compression spring are arranged in the cavity body of the fixing block and a positioning clamping tooth of the traction plate positioning rod extends out of the tooth hole on the top surface of the cavity body to be matched with the sawtooth-shaped clamping groove of the traction plate; and the cover board is arranged at the bottom of the cavity body of the fixing block.
Description
Technical field
The present invention relates to a kind of soft palate pulling device wearing Vickers gag, it belongs to a kind of operation medical apparatus and instruments.
Background technology
Adenoid vegetation causes child's respiratory disorder common disease, and excision proventriculus type is the most effective Therapeutic Method.Because child's nasal cavity is less, approach more options oral approach, simultaneously, due to the extensive use of nasal sinuses mirror, scope resection proventriculus type advantage makes ear-nose-throat doctor accept extensively this modus operandi, in operation, nasopharynx part exposure many application catheter or sputum aspirator tube pass through, and catheter easily makes nasal membrane damage cause epistaxis to occur, simultaneously, because catheter cannot tractive uvula, uvula still hinders the observation of scope, is unfavorable for operation and operation safety, easily causes uvula iatrogenic injury.
Summary of the invention
The object of the invention is to solve existing surgical instrument and there is the technical problem easily making nasal membrane damage and easily cause uvula iatrogenic injury, provide a kind of structure simple, easy to operate and nasal membrane and the staphyleus soft palate pulling device wearing Vickers gag can not be damaged.
The present invention solves the problems of the technologies described above the technical scheme adopted to be: the soft palate pulling device wearing Vickers gag, it comprises Compress Spring, wherein: it also comprises drawing plate, fixed block, drawing plate locating rod and cover plate, the top of fixed block is provided with one and is arranged on the draw-in groove worn on Vickers gag, the flat groove of a placement drawing plate is provided with in the below of draw-in groove, a cavity is provided with in the bottom of fixed block, the end face central authorities of cavity are provided with a perforation communicated with flat groove bottom, drawing plate is contained in the flat groove of fixed block, drawing plate locating rod and Compress Spring are contained in the cavity of fixed block and the zigzag draw-in groove of the location latch of the drawing plate locating rod perforation and drawing plate that stretch out cavity end face matches, cover plate is located at the bottom of fixed block cavity and drawing plate locating rod and Compress Spring is fixed in the cavity of fixed block.
One end of described drawing plate is oblate arc shape and upwards micro-ly sticks up, and the bottom of drawing plate postmedian is provided with zigzag draw-in groove.
The horizontal axis of the opening direction of the flat groove of described fixed block differs 90 ° with the horizontal axis of the opening direction of fixed block draw-in groove.
Described drawing plate locating rod is made up of cylinder, spring cap and location latch, and one end of spring cap is located at cylindrical end, and location latch is located at the other end of spring cap and is positioned at the central authorities of spring cap.
Owing to present invention employs technique scheme, in the operation of Adenoid dectomy, surgical field of view can be made openr, strengthen the space of patient's operation, be conducive to the carrying out of performing the operation.Meanwhile, the adverse consequences of the operating procedure adopting catheter or sputum aspirator tube to expose nasopharynx part by nasal cavity and the bronchia mucosal damage brought thereof is avoided in current adenoidectomy.Therefore, compared with background technology, it is simple that the present invention has structure, easy to operate, is convenient to patient and uses, Reusability of can sterilizing, cost-saving, reduces the wasting of resources, can not damage the advantage such as nasal membrane and uvula.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, the soft palate pulling device wearing Vickers gag in the present embodiment, it comprises Compress Spring 3, wherein: it also comprises drawing plate 1, fixed block 2, drawing plate locating rod 4 and cover plate 5, the top of fixed block 2 is provided with one and is arranged on the draw-in groove 6 worn on Vickers gag, the flat groove 7 of a placement drawing plate is provided with in the below of draw-in groove 6, a cavity is provided with in the bottom of fixed block 2, the end face central authorities of cavity are provided with a perforation communicated with flat groove 7 bottom surface, drawing plate 1 is contained in the flat groove 7 of fixed block, drawing plate locating rod 4 and Compress Spring 3 are contained in the cavity of fixed block 2 and the zigzag draw-in groove of the location latch 8 of drawing plate locating rod 4 perforation and drawing plate 1 that stretch out cavity end face matches, cover plate 5 is threaded connection in the bottom of fixed block 2 cavity and is fixed in the cavity of fixed block 2 by drawing plate locating rod 4 and Compress Spring 3, and make the bottom of drawing plate locating rod 4 expose the hole of cover plate 5 setting, so that the location of drawing plate 1.One end of above-mentioned drawing plate 1 is oblate arc shape and upwards micro-ly sticks up, and the bottom of drawing plate 1 postmedian is provided with zigzag draw-in groove.The horizontal axis of the opening direction of the flat groove 7 of above-mentioned fixed block differs 90 ° with the horizontal axis of the opening direction of fixed block draw-in groove 6.Above-mentioned drawing plate locating rod 4 is made up of cylinder 10, spring cap 9 and location latch 8, and one end of spring cap 9 is located at the end of cylinder 10, and location latch 8 is located at the other end of spring cap 9 and is positioned at the central authorities of spring cap 9.
Work process of the present invention is: as shown in Figure 5, and be first fixed on Buccodental by gag 11 upper end during use, patient's tongue pushed down by bottom spatula, opened in oral cavity, then is arranged on gag 11 by fixed block 2 by draw-in groove 6; The flat arc end of drawing plate 1 is stretched into below patient's soft palate, simultaneously downward light dragline arm-tie locating rod 4, make drawing plate 1 can load in the flat groove 7 of fixed block 2 setting from the side; Drawing plate locating rod 4 pops up under Compress Spring 3 acts on, and location latch 8 snaps in the zigzag draw-in groove below drawing plate 1; Now to oral external dragline arm-tie 1, soft palate is made upwards to hold up correct position.Location latch 8 due to drawing plate locating rod 4 is stuck in the zigzag draw-in groove of drawing plate 1, and drawing plate 1 can not return oral cavity due to the resilience of soft palate, also can not skid off from fixed block 2 side.
