Abstract
The utility model relates to an operative medical appliance used in rhinology. The utility model is composed of a vice bench type base, a supporting frame and a hook mechanism. The hook mechanism can effectively drag the thyroid hook which is used currently. In addition, the height and the angles of the hook mechanism can be adjusted optionally in order to satisfy operative needs. The utility model has the advantages of easy use, and low cost. The operative doctors'labor intensity can be alleviated, and the utility model is suitable for hospitals of all levels.
Description
This utility model relates to a kind of medical surgical instrument.
Maxillary antrum operation is one of nose section routine operation, is the effective means of radical cure all kinds of pathological changes of maxillary sinus (comprising maxillary sinus chronic inflammatory disease, polyp, mycete and tumor etc.).General district level is with feasible this operation of going to the hospital.The main route of performing the operation is a labiogingival incision, and otch is positioned at by the labiogingival groove, maxillary sinus antetheca below.The position is hidden, last tension force is big, and art is wild dark, must be to the soft tissue on side tractive otch top, the crown in the art, comprise upper lip, hole front face soft tissue, about 2～3Kg simultaneously must apply the about 1Kg of pressure backward, in case underlying soft tissue slippage and hide the art open country, the operation overall process needs an assistant to continue the manpower drag hook, and at any time according to surgical field of view needs conversion drag hook angle, not only assistant's physical demands is big, and can not free hand to cooperate operation.Once had many people to manage to improve this for many years and fall behind situation, high because of the requirement of drag hook adjustability eventually, not seeing so far has satisfactory substitute, and present hospitals at different levels still adopt this ancient manual mode.
The purpose of this utility model is, a kind of drag hook that replaces manual labour is provided.When this drag hook is used to retract labiogingival incision, can fully expose maxillary sinus art open country, regulate arbitrarily, be suitable for various operating-tables and various build patient.
For achieving the above object, this utility model is made up of base, bearing support, drag hook mechanism, base has comprised deckle board, set bolt, scalable fixing head, the scalable fixing head is installed in the upper end of set bolt, set bolt passes the following side plate of deckle board, the turn set bolt, and the scalable fixing head moves up and down in the upper and lower side plate of deckle board, the side of deckle board is one to have the union joint of horizontal opening fourth of the twelve Earthly Branches groove, and connecting bolt and direction fixed screw are arranged on this union joint; Bearing support has comprised L molded cannula and vertical rod, there is a horizontal tenon horizontal component termination of L molded cannula, this tenon embeds in the opening fourth of the twelve Earthly Branches groove of deckle board union joint, connecting bolt flexibly connects tenon and fourth of the twelve Earthly Branches groove, unclamp the direction fixed screw, but the sleeve pipe along continuous straight runs moves, the upper end of vertical rod has one to erect tenon in the bearing support, the vertical rod lower end is inserted in the L molded cannula vertical component, and the degree of depth of insertion can be regulated, with vertical rod fixed screw location; Drag hook mechanism comprises sawtooth cross bar and cross bar sleeve pipe, the sawtooth cross bar is horizontally through the cross bar sleeve pipe, one end of sawtooth cross bar has drag hook link and drag hook making leaf spring, there is a breach cross bar sleeve pipe top, this indentation, there has a cross bar non-return stage clip can make that the sawtooth cross bar is unidirectional to be tightened up, stir cross bar non-return stage clip, the sawtooth cross bar could move freely in the cross bar sleeve pipe.The cross bar sleeve bottom has one to have the union joint of erectting opening fourth of the twelve Earthly Branches groove, and the tenon of vertical rod upper end embeds this fourth of the twelve Earthly Branches groove, and cross bar break-in screw had both made tenon be connected with fourth of the twelve Earthly Branches groove, and the cross bar sleeve pipe is regulated in vertical rod upper end left-handed (or dextrorotation).
This utility model advantage is similar mechanical hand, its alternative assistant one people.Because what use is former surgery tractor (goitre retractor), so does not influence operation process, and the patient is not had addition reaction, has alleviated the labor intensity of operative doctor greatly, the pulling force of drag hook, direction is regulated arbitrarily, and is easy to use, wild satisfaction, the low cost of exposing of art.Be applicable to each level hospital, use through how tame hospital clinical such as Nanjing drum tower hospital, municipal first hospital and Aug. 1st hospital over one year to reach over one hundred example, generally acknowledge that result of use is satisfied, quite be subjected to the welcome of operative doctor.
Accompanying drawing 1 this utility model structure cutaway view.
Below in conjunction with accompanying drawing, introduce a most preferred embodiment of the present utility model.As shown in Figure 1, it is desk-top that base (1) is pincers, and bearing support (2) horizontal section length is 11 centimetres, vertical section length is 30～50 centimetres, sawtooth cross bar (3) length is 32 centimetres, and cross bar sleeve pipe (4) top has a breach, this indentation, there to have a cross bar non-return stage clip (5) card to be pressed in the sawtooth ditch, the cross bar left end is drag hook link (6), there is drag hook making leaf spring (7) the link top, and it is square that this reed is the broadband, the slightly broadening of free ora terminalis, one wide 1.75 centimetres of breach are arranged, for card is pressed drag hook arm place.Drag hook making leaf spring and cross bar non-return making leaf spring are selected for use hard and favorable elasticity are arranged and flexible steel disc is made.
