Description
Technical field
This utility model relates to a kind of soft palate pulling device of wearing Vickers gag, and it belongs to a kind of operation medical apparatus and instruments.
Background technology
Adenoid vegetation is to cause child's respiratory disorder common disease, and excision gland sample body 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 gland sample body advantage makes ear-nose-throat doctor accept extensively this modus operandi, in operation, nasopharynx part exposure many application catheters 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 purpose of this utility model is to solve existing surgical instrument to exist and easily make nasal membrane damage and easily cause the technical problem of uvula iatrogenic injury, provides a kind of simple in structure, easy to operate and can not damage nasal membrane and the staphyleus soft palate pulling device of wearing Vickers gag.
This utility model is to solve the problems of the technologies described above the technical scheme adopting to be: the soft palate pulling device of 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 of wearing on Vickers gag, below draw-in groove, be provided with the flat groove of a placement drawing plate, in the bottom of fixed block, be provided with a cavity, the end face central authorities of cavity are provided with a perforation communicating 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 location latch of drawing plate locating rod stretches out the perforation of cavity end face and the zigzag draw-in groove of drawing plate 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 micro-the sticking up that make progress, and the bottom of drawing plate postmedian is provided with zigzag draw-in groove.
The horizontal axis of the horizontal axis of the opening direction of the flat groove of described fixed block and the opening direction of fixed block draw-in groove differs 90 °.
Described drawing plate locating rod consists 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.
Because this utility model has adopted technique scheme, in the operation of gland sample body excision, can make surgical field of view openr, strengthen the space of patient's operation, be conducive to the carrying out of operation.Meanwhile, avoided adopting catheter or sputum aspirator tube to expose the operating procedure of nasopharynx part by nasal cavity in current adenoidectomy and the adverse consequences of the bronchia mucosal damage that brings.Therefore, compare with background technology, the utlity model has simple in structurely, easy to operate, be convenient to patient and use, the Reusability of can sterilizing, cost-saving, reduce the wasting of resources, can not damage the advantages such as nasal membrane and uvula.

The specific embodiment
Below in conjunction with drawings and Examples, this utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, the soft palate pulling device of 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 of wearing on Vickers gag, below draw-in groove 6, be provided with the flat groove 7 of a placement drawing plate, in the bottom of fixed block 2, be provided with a cavity, the end face central authorities of cavity are provided with a perforation communicating with flat groove 7 bottom surfaces, 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 location latch 8 of drawing plate locating rod 4 stretches out the perforation of cavity end face and the zigzag draw-in groove of drawing plate 1 matches, cover plate 5 is threaded connection in the bottom of fixed block 2 cavitys and by drawing plate locating rod 4 and Compress Spring 3 and is fixed in the cavity of fixed block 2, and the hole that cover plate 5 arranges is exposed in the bottom that makes drawing plate locating rod 4, so that the location of drawing plate 1.One end of above-mentioned drawing plate 1 is oblate arc shape and micro-the sticking up that make progress, and the bottom of drawing plate 1 postmedian is provided with zigzag draw-in groove.The horizontal axis of the horizontal axis of the opening direction of the flat groove 7 of above-mentioned fixed block and the opening direction of fixed block draw-in groove 6 differs 90 °.Above-mentioned drawing plate locating rod 4 consists of cylinder 10, spring cap 9 and location latch 8, and one end of spring cap 9 is located at cylinder 10 end, 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 utility model is: as shown in Figure 5, first gag 11 upper ends are fixed on to Buccodental Shang， bottom and with spatula, are pushed down patient's tongue ，Jiang oral cavity and open, then fixed block 2 is arranged on gag 11 by draw-in groove 6 during use; The flat arc end of drawing plate 1 is stretched into patient's soft palate below, and downward light dragline arm-tie locating rod 4, can pack in the flat groove 7 of fixed block 2 settings drawing plate 1 from the side into simultaneously; Drawing plate locating rod 4 pops up under Compress Spring 3 effects, and location latch 8 snaps in the zigzag draw-in groove of drawing plate 1 below; Now, to oral external dragline arm-tie 1, make soft palate upwards hold up correct position.Because the location latch 8 of drawing plate locating rod 4 is stuck in the zigzag draw-in groove of drawing plate 1, drawing plate 1 can, because oral cavity is return in the resilience of soft palate, can not skid off from fixed block 2 sides yet.
