Abstract
A double-headed hollow forcing screw relates to the field of medical instrument, and comprises a hollow screw body, a first thread and a second thread. The first thread is arranged at one end of the hollow screw body, and the second thread is arranged at the other end of the hollow screw body. The problems that a fracture surface cannot tightly healed after the hollow screw is screwed into the fracture surface and the screw is easy to loosen and slip can be resolved, and the double-headed hollow forcing screw is stable and firm.
Description
Technical field:
This utility model relates to medical instruments field, is specifically related to the hollow forcing screw of a kind of double end.
Background technology:
Along with China's aged tendency of population, old fracture of femoral neck sickness rate improves constantly, because senile osteoporosis and neck of femur ischemia, bone does not connect and femur head necrosis take place easily, so this fracture has become the geriatrics important topic, along with the improvement of surgical condition and the accumulation of operation skill, C type arm is had an X-rayed the first-selection that advantages such as emergency treatment row double end compressive hollow screw internal fixation is short with its operating time down, wound is little, the hospital stays holds, expense is low become basic hospital and patient.
Existing hollow screw only has an end that screw thread is arranged, and the other end does not have screw thread, easily causes the healing of fracture face not tight, the easily loosening slippage of nail.
The utility model content:
The purpose of this utility model provides the hollow forcing screw of a kind of double end, and it is not tight that it solves the fracture face healing of hollow screw screw-in back, and nail becomes flexible slip phenomenon easily, and is not only stable but also firm.
In order to solve the existing problem of background technology, this utility model is by the following technical solutions: it comprises hollow screw body 1, one end of hollow screw 1 is provided with the first screw thread 1-1, and it also comprises the second screw thread 1-2, and the second screw thread 1-2 is arranged on the other end of hollow screw 1.
The utlity model has following beneficial effect: it is not tight that the solution hollow screw screws in back fracture face healing, and the easy loosening slip phenomenon of nail is not only stable but also firm.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment by the following technical solutions: it comprises hollow screw body 1, and an end of hollow screw 1 is provided with the first screw thread 1-1, and it also comprises the second screw thread 1-2, and the second screw thread 1-2 is arranged on the other end of hollow screw 1.
This specific embodiment is because the difference of the screw two ends pitch of thread can make the screw two ends pressurize to the center during screw-in, and the fracture face is closely chimeric; The two ends screw thread all embeds sclerotin, and nail is difficult for loosening, slippage, and fracture end is firm; Screw is screwed into by strong oblique interior top in the art, moves towards consistent in fracture compressive stress, tension with the femoral neck bone girder.
It is not tight that this specific embodiment solves the fracture face healing of hollow screw screw-in back, and nail becomes flexible slip phenomenon easily, and is not only stable but also firm.
