Abstract
The utility model discloses a fracture fixing aiming device which belongs to the technical field of medical instruments and is characterized in that the upper end and the lower end of a handle are respectively provided with an upper guiding pipe and a lower guiding pipe in parallel. A hollow sleeve is sheathed in the lower guiding pipe. The front end surface and the back end surface of a straight rod section of an aiming positioning rod are parallel, the upper end surface and the lower end surface are in an arc shape, and arc-shaped surfaces are provided with threads. The straight rod section of the aiming positioning rod is inserted into the upper guiding pipe of an inner chamber adapted to the structure of the straight rod section, and the straight rod section of the aiming positioning rod extending out of the two ends of the upper guiding pipe is respectively provided with a fixing nut, the front end of the aiming positioning rod is downwards bent, and the top end of the aiming positioning rod is provided with a screw guiding hole. The screw guiding hole, the lower guiding pipe and the sleeve form a straight line. The aiming positioning rod can not rotate in the upper guiding pipe, and the positioning is accurate, thus, the problem of difficult fixation caused by the inaccurate screwing direction of the fixing screw and the movement of fracture blocks is solved. In the operation process, tissues are not required to be excessively stripped off, thus, the damage on soft tissues is avoided, the fracture healing rate is increased, and the pain of a patient is relieved.
Description
Technical field
This utility model belongs to technical field of medical instruments, and specifically a kind of fracture fixation sight is used for the direction orientation direction of reduction of the fracture hold-down screw.
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 the good blood supply of protection soft tissue and 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 supply of soft tissue and bone, influenced union of fracture.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of fracture fixation sight is provided, and 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.
The purpose of this utility model be achieved in that this fracture fixation sight by handle, go up guide pipe, guide pipe, sleeve, aiming locating rod, hold-down nut are formed down, the two ends up and down of handle are respectively equipped with last guide pipe and the following guide pipe that is parallel to each other, cannulated sleeve is sleeved on down in the guide pipe, and internal fixation screw can pass through in it; Aiming locating rod straight bar section front/rear end is parallel, the upper and lower end face is curved, on arcwall face, be provided with screw thread, the straight bar section of aiming locating rod is inserted in the last guide pipe that inner chamber and straight bar section structure adapt, it stretches out on the straight bar section at guide pipe two ends hold-down nut is housed respectively, and hold-down nut can be adjusted its outreach and be fixed, and aiming locating rod front end is bent downwardly, the top is provided with the screw bullport, and the screw bullport constitutes straight line with following guide pipe, sleeve.
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, according to the direction that the direction of pre-screw-in screw is regulated the fracture fixation sight, the nut that is tightened then screws in screw by sleeve and gets final product with fixed index.
Advantage of the present utility model: simple in structure, processing ease, the aiming locating rod can not rotate in last guide pipe, 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, avoid, improve the union of fracture rate, reduce patient's misery soft tissue destruction to organizing.
Description of drawings
Accompanying drawing is a structure chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this fracture fixation sight is made up of handle 1, last guide pipe 2, following guide pipe 3, sleeve 4, aiming locating rod 5, hold-down nut 6, the two ends up and down of handle 1 are respectively equipped with last guide pipe 2 and the following guide pipe 3 that is parallel to each other, and are with cannulated sleeve 4 in the following guide pipe 3; The straight bar section front/rear end of aiming locating rod 5 is parallel, the upper and lower end face is curved, on arcwall face, be provided with screw thread, the straight bar section of aiming locating rod 5 is inserted in the last guide pipe 2 that inner chamber and straight bar section structure adapt, it stretches out on the straight bar section at guide pipe 2 two ends hold-down nut 6 is housed respectively, aiming locating rod 5 front ends are bent downwardly, and the top is provided with screw bullport 7, and screw bullport 7 constitutes straight line with following guide pipe 3, sleeve 4.
