Abstract
The utility model discloses a small trochanteric reduction sighting device which is convenient to operate, has various functions and is accurate to position. The small trochanteric reduction sighting device comprises two operating handles which are hinged mutually. The operating handles are connected with clamping handles. An adjusting fixing device is arranged on the operating handles. The adjusting fixing device consists of an adjusting screw and a fixing screw cap at the end part of the adjusting screw. One end of the adjusting screw is fixedly connected with one operating handle and is movably connected with the other operating handle. The fixing screw cap is arranged at one end of the adjusting screw. The end parts of the clamping handles are respectively provided with sighting holes. Internal screw threads are formed in the sighting holes. The small trochanteric reduction sighting device is suitable for intertrochanteric fracture reduction therapy.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of intertrochanteric fracture reduction therapy that is applicable to.
Background technology
Intertrochanteric fracture is very common clinically classification of fracture; intertrochanteric fracture often is shifted with fracture of the lesser trochanter; generally all not carrying out lesser trochanter when the lesser trochanter sclerite does not add up bigelow's septum fixes; but when lesser trochanter of femur accumulative total bigelow's septum, need carry out fully effectively fixing to lesser trochanter; in order to avoid influence Adductorius normal biomechanics; prevent that fracture surgery from interior talipes varus taking place, and influences patient's normal activity.Still lack a effective lesser trochanter resetting tool at present clinically.
The utility model content
The lesser trochanter that the technical problems to be solved in the utility model provides a kind of easy to operate, diverse in function, the accurate positioning sight that resets.
In order to solve the problems of the technologies described above, this utility model is achieved through the following technical solutions:
This utility model comprises two operating grips that are hinged, described operating grip is connected with grip shank, described operating grip is provided with the adjusting fixture, described adjusting fixture is made up of the hold-doun nut of adjusting screw(rod) and adjusting screw(rod) end, described adjusting screw(rod) one end is fixedlyed connected with operating grip wherein, and flexibly connect with the another operating grip, described hold-doun nut is located at adjusting screw(rod) one end, described grip shank end is respectively equipped with sight hole, is provided with female thread in the described sight hole.
As preferably, described grip shank inboard is respectively equipped with sawtooth.
This utility model compared with prior art has following obvious advantage and beneficial effect:
1, easy to operate.Owing to be provided with the adjusting fixture in this utility model, can lock and fix the front end clamping, the doctor need not to use hands to carry out clamping in practical operation always, thereby makes easy to operate.
2, diverse in function.Because this utility model grip shank end is respectively equipped with sight hole, this sight hole not only can be installed sighting bar, and can carry out steel wire and connect, thereby diverse in function.
3, accurate positioning.Since this utility model finish reset, grip after, need not to take off, it is effectively fixing to use screw that fracture is carried out, thereby has improved the accuracy of position.

The specific embodiment
Below in conjunction with the drawings and the specific embodiments this utility model is described in further detail:
As shown in Figure 1 and Figure 2: this utility model comprises two operating grips 1,2 that are hinged, operating grip 1 is connected with grip shank 3, operating grip 2 is connected with grip shank 4, operating grip 1,2 is provided with the adjusting fixture, regulating fixture is made up of the hold-doun nut 6 of adjusting screw(rod) 5 and adjusting screw(rod) 5 ends, adjusting screw(rod) 5 one ends are fixedlyed connected with operating grip 1, and flexibly connect with operating grip 2, hold-doun nut 6 is located at adjusting screw(rod) 5 one ends, grip shank 3 ends are provided with sight hole 7, grip shank 4 ends are provided with sight hole 8, are provided with female thread in the sight hole 8; Grip shank 2 inboards are provided with sawtooth 9, and grip shank 3 inboards are provided with sawtooth 10.
This utility model utilizes the grip shank front end to the fracture end clamping that resets in use, utilizes adjusting fixture on the operating grip to lock and fixing again, and the doctor need not to use hands to carry out clamping in practical operation always; Simultaneously be provided with sight hole in the grip shank end, sight hole designs for female thread, can with have externally threaded guide pin and cooperate, to play good positioning action; Corresponding in addition sight hole lesser trochanter retaining part is a hollow design, can effectively bore lesser trochanter cortex; 1. when using steel wire fixedly the time, steel wire directly can be drawn through outside sight hole, osseous tunnel, offside sight hole, can finish steel wire through tractive and connect lesser trochanter; 2. when with screw fixedly the time, screw can fully see through lesser trochanter, thereby effectively replys the bigelow's septum integrity, increases fracture end stability greatly; Finish reset, grip after, need not to take off this utility model, that is: take off and to use behind the guide pin screw that fracture site is carried out effectively fixing (the screw tail end is generally 4.5mm or 6mm), avoided conventional reduction forceps after fracture end is resetted, to need other position that fracture site is fixed, because the reduction forceps fixed position is fixedly optimum position of fracture site generally speaking.
Claims (2)
