Abstract
The utility model discloses a fracture fixation pointer, which comprises a handle, a sighting positioning bar, a hub, and a binding nut. Wherein, parallel guiding tubes upside and downside are respectively arranged on the top and bottom of the handle, the hollow hub is arranged in the downside guiding tube. The end of the sighting positioning bar of spiral structure is plugged in the upside guiding tube. Positioning nuts, which are arranged on the two ends of the guiding tube, adjust the extending distance and fix the sighting positioning bar. The front of the sighting positioning bar curves downside, a screw guiding hole is on the top, and constructs a line with the downside guiding tube and the hub. The utility model has the advantages that the structure is simple, the operating is easy, and the positioning is accurate. The inaccurate spiral direction of fixed screw and the difficult fixing of the fracture are no longer problems. During the operation, organizations need not be stripped excessively. The damage of blood supply for parenchyma and bone is avoided, the knitting ratio is improved, and pains of patients are reduced.
Description
Technical field
This utility model discloses a kind of fracture fixation sight, is used for the direction orientation direction of reduction of the fracture hold-down screw, belongs to the orthopedic medical device technical field of structures.
Background technology
In the orthopaedic medical treatment process; the internal fixation treatment principle of fracture mainly concentrates on the method for using careful operation and softly resetting; under the prerequisite of protection soft tissue and the good blood confession of bone, according to individual need resetting of selecting that suitable internal fixation material fractures with rebuild.
In the clinical practice, many fracture are comparatively complicated comminuted fracture, fix during treatment in the process of this class anatomy relationship of this type of fracture and similar fracture of pelvis than complicated fracture, for internal fixation screw being screwed in good direction, make it to have stronger hold and to the set effect of sclerite, often needing to peel off a large amount of soft tissues, to appear art wild and be convenient to operation.Violate the internal fixation principle of fracture virtually, destroyed the blood confession of soft tissue and bone, influenced union of fracture.
Summary of the invention
This utility model discloses a kind of fracture fixation sight, has solved the problem that need peel off a large amount of soft tissues in the bone surgery for definite internal fixation screw screw-in direction.
Technical solution of the present utility model is as follows: form sight by handle, aiming locating rod, sleeve, hold-down nut, wherein, the two ends up and down of handle are respectively equipped with parallel upper and lower guide pipe, and cannulated sleeve is sleeved on down in the guide pipe, and internal fixation screw can pass in it; Aiming locating rod afterbody is a helicitic texture, is inserted in the guide pipe, and its two ends of stretching out guide pipe are equipped with setscrew nut, can adjust its outreach and be fixed, the front end of aiming locating rod is bent downwardly, and the top is provided with the screw bullport, constitutes straight line with following guide pipe, sleeve.
When this utility model uses, after treating the reduction of the fracture, the osseous tissue that need are screwed or (and) blade plate is as between sleeve and the aiming locating rod, regulate the direction of fracture fixation sight according to the direction of pre-screw-in screw, nut be tightened then with fixed index, screw in screw by sleeve and get final product.
Good effect of the present utility model is: sight frame for movement is simple, processing ease, and accurate positioning, it is inaccurate to have solved the hold-down screw screw-in direction, and sclerite moves and is difficult for fixed problem.In the operation process, do not need excessively to peel off, avoided destruction, improved the union of fracture rate, reduced patient's misery the blood confession of soft tissue and bone to organizing.
