Abstract
The invention aims to solve the problem that a surgical incision for taking out a bone fracture plate screw is large in the field of medical technology, provides a minimally invasive bone fracture plate screw extraction method, and provides a minimally invasive positioning device for extracting a bone fracture plate screw. The minimally invasive positioning device comprises a bone fracture plate surface tissue peeler, a bone fracture plate screw positioner, and a handle. An application method of the minimally invasive positioning device includes: making a 1-2cm long incision at one end of an original surgical incision, holding the handle, pushing forward to tightly attach the bone fracture plate surface tissue peeler to tissue adhered to the surface of a bone fracture plate, allowing a U-shaped opening at the front end of the tissue peeler to contact with a screw tail cap protruding the surface of the bone fracture plate, allowing a screw positioner positioning hole above the tissue peeler to exactly face to a screw hole, inserting a screw wrench through the screw positioning hole to move the screw from the small incision, sequentially taking out other screws, and extracting the bone fracture plate from the small incision to complete a surgery.
Description
Technical field
The present invention relates to a kind of technical field of medical.
Background technology
Prior art when the second operation after human fracture's healing takes out the blade plate screw, needs bigger operative incision at present, could take out the blade plate screw that places in the body to appear the blade plate total length, cause tissue injury heavy, operating time prolongs, and has increased patient's misery and wound.
Summary of the invention
The present invention seeks to avoiding the big otch of operation of the prior art, reduce patient trauma and provide a kind of simple to operate, utilization rate is high, the fracture blade plate screw positioner of the taking-up of low cost of manufacture fracture blade plate screw.
The present invention includes a blade plate surface texture detacher, a blade plate screw positioner, a handle formation.Blade plate surface texture detacher front end is flat sharp keen, the opening that takes the shape of the letter U, and blade plate surface texture detacher tail end connects handle.The blade plate screw positioner is positioned at the top of blade plate surface texture detacher, and both are parallel, and blade plate screw positioner free-end has-the screw locating hole.
During use, holding handle promotes forward, make blade plate surface texture detacher be close to the blade plate surface, peel off the tissue of adhesion, when the U-shaped opening of blade plate surface texture detacher front end touches the screw tail medicated cap that protrudes from the blade plate surface, then meet obstructions and to continue to move ahead, organize this moment the screw positioner locating hole of detacher top namely over against answering this piece screw hole, insert screw wrench through the screw locating hole and can under miniature incision, take out screw.The existing surgical technic of comparing, the otch wound surface is little by about 80%, and doctor's operation technique is quick, safety, has improved efficient and the quality of operation, has reduced patient's operation wound.
Apparatus structure of the present invention is simple, and is sturdy and durable, is convenient to cleaning and sterilizing; Simultaneously, simple small and exquisite structure also makes the length of the edge of a knife significantly dwindle, and makes patient's the easier recovery of wound.
Description of drawings
Fig. 1 is operation technique figure of the prior art.
Fig. 2 is structure chart of the present invention.
Fig. 3 is application demonstration graph of the present invention.
The specific embodiment
As shown in Figure 2, blade plate surface texture detacher 1 is connected the front end of handle 2, and blade plate screw positioner 3 is positioned at the top of blade plate surface texture detacher 1, and both are parallel, and blade plate screw positioner free-end has a screw locating hole 4.Blade plate surface texture detacher 1 of the present invention and rear end handle 2 are as a whole, process through forging, and blade plate screw positioner 3 is weldingly connected with blade plate surface texture detacher 1 shank, and is cheap for manufacturing cost.
Claims (2)
1. fracture blade plate screw positioner, it is characterized in that comprising that a blade plate surface texture detacher, a blade plate screw positioner, a handle constitute, the blade plate screw positioner is positioned at the top of blade plate surface texture detacher, both are parallel, and blade plate screw positioner free-end has a screw locating hole.
2. a kind of fracture blade plate screw positioner according to claim 1 is characterized in that blade plate surface texture detacher front end is flat sharp keen, and opening takes the shape of the letter U.
