Abstract
The invention discloses an alignment clamp for lesser trochanter reduction, which has the advantages of convenient operating process, multiple functions and accurate positioning. The alignment clamp comprises two operating handles which are hinged with each other, wherein each operating handle is connected with a gripping handle and is provided with an adjusting and fixing device; the adjusting and fixing device comprises an adjusting screw and a fixing nut arranged at the end part of the adjusting screw; one end of the adjusting screw is fixedly connected with one operating handle and flexibly connected with the other operating handle; the fixing nut is arranged at the other end of the adjusting screw; the end parts of the gripping handle are respectively provided with an alignment hole; and an internal thread is arranged in the alignment hole. The invention is applicable to the reduction treatment of intertrochanteric fracture.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate 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.
Summary of the invention
The lesser trochanter that the technical problem to be solved in the present invention 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, the present invention is achieved through the following technical solutions:
The present invention includes 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 connects with the another operating grip, and 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.
The present invention compared with prior art has following obvious advantage and beneficial effect:
1, easy to operate.Owing to be provided with the adjusting fixture among the present invention, 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 grip shank of the present invention 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 the present invention 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
The present invention is described in further detail below in conjunction with the drawings and the specific embodiments:
As shown in Figure 1 and Figure 2: the present invention includes 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.
The present invention 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 the present invention, 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)
1. lesser trochanter sight that resets, comprise two operating grips that are hinged, described operating grip is connected with grip shank, it is characterized in that 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.
2. the lesser trochanter according to claim 1 sight that resets is characterized in that described grip shank inboard is respectively equipped with sawtooth.
