Abstract
The utility model relates to an inner fixer used for the femoral intertrochanteric fracture. The inner fixer used for the femoral intertrochanteric fracture comprises a bone fracture plate and a main nail arranged on the bone fracture plate, an auxiliary bone fracture plate is arranged on the outer sidewall of the bone fracture plate, and a claw shaped hook is arranged at the upper end of the auxiliary bone fracture plate. Because the auxiliary bone fracture plate is arranged on the outer sidewall of the bone fracture plate, the main nail is prevented from being disengaged from the bone effectively, and because the claw shaped hook is arranged at the upper end of the auxiliary bone fracture plate, the claw shaped hook can be used for fixing the fracture fragments of greater trochanter part effectively, and the problem that the fracture at the greater trochanter part can not be fixed in the prior art is resolved.
Description
Technical field
This utility model relates to a kind of inner fixer that is used for intertrochanteric fracture.
Background technology
At present, often adopt DHS plate in treating intertrochanteric fracture clinically.The structure of DHS blade plate as shown in Figure 1, an end of blade plate 1 is provided with the blade plate master and follows closely 2.If fracture is pulverized, during particularly with pertrochanteric fracture, use fixedly pertrochanteric fracture piece of DHS blade plate.In order to prevent that the pertrochanteric fracture piece from separating, normally on DHS blade plate basis, utilize the breastbone wire binding to fix, exist fixing not firm drawback.And DHS blade plate master is taken place and is followed closely 2 complication of deviating from the part patient clinically.
Summary of the invention
In order to address the above problem, the purpose of this utility model provides a kind of effectively fixedly pertrochanteric fracture piece and prevents the inner fixer that is used for intertrochanteric fracture that main nail is deviate from.
To achieve the above object, this utility model is mainly solved by following technical proposals:
A kind of inner fixer that is used for intertrochanteric fracture comprises blade plate and the main nail that is arranged on the blade plate, and the lateral wall of described blade plate is provided with auxilliary blade plate, and the upper end of auxilliary blade plate is provided with the claw type hook.
Also be provided with screw on the above-mentioned auxilliary blade plate, described screw is between claw type hook and the main nail.
Because this utility model is provided with auxilliary blade plate on the lateral wall of blade plate, prevented that effectively main nail from deviating from bone, the upper end of auxilliary blade plate is provided with the claw type hook, the claw type hook can be effectively the fixing sclerite at greater trochanter position, solved in the prior art the fixedly problem of greater trochanter position fracture.
Description of drawings
Fig. 1 is the prior art constructions sketch map.
Fig. 2 is the structural representation of this utility model embodiment.
Fig. 3 is the structural representation of this utility model claw type hook 3 deployed conditions.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the technical solution of the utility model is described in further detail.
Embodiment: a kind of inner fixer that is used for intertrochanteric fracture comprises blade plate 1 and the main nail 2 that is arranged on the blade plate 1.The lateral wall of blade plate 1 is provided with auxilliary blade plate 5, and auxilliary blade plate 5 is provided with screw 6.The upper end of auxilliary blade plate 5 is provided with claw type hook 3.Claw type hook 3 and auxilliary blade plate 5 are one-body molded, the employing Nitinol is made, because of it has can be better moulding in mixture of ice and water, behind the rewarming automatically retraction from original this characteristic of hook-type state, like this, the trochiterian different shape that individual variation causes on the anatomy all can obtain effectively fixing.Also be provided with screw 4 on the auxilliary blade plate 5, described screw 4 is between claw type hook 3 and the main nail 2, has effectively overcome the problem of fracture end rotation.Loosening in order to prevent screw 4, can adopt thread lock between screw 4 and the auxilliary blade plate 5.
During use, insert the blade plate master earlier after by the medical science routine intertrochanteric fracture being resetted and follow closely 2, be inserted in blade plate 1 to submissive.Install before the auxilliary blade plate in advance its a plurality of claw type hook 3 moulding, to assist blade plate 5 then adheres on blade plate 1 lateral wall, pass screw 6 fixing afterwards claw type hook 3 being resetted of assisting on the blade plate 5 with several pieces of os integumentale screws, claw type hook 3 returns to original hook-shaped form, the pertrochanteric fracture piece is well secured, tighten screw 4 at last, promptly finish enforcement.
Claims (2)
1, a kind of inner fixer that is used for intertrochanteric fracture, the master who comprises blade plate (1) and be arranged on the blade plate (1) follows closely (2), it is characterized in that the lateral wall of described blade plate (1) is provided with auxilliary blade plate (5), the upper end of auxilliary blade plate (5) is provided with claw type hook (3).
2, a kind of inner fixer that is used for intertrochanteric fracture according to claim 1 is characterized in that, also is provided with screw (4) on the described auxilliary blade plate (5), and described screw (4) is between claw type hook (3) and the main nail (2).
