Abstract
The utility model discloses a locking type goose head nail, which belongs to a bone fixing appliance used in orthopedic operation. The locking type goose head nail comprises a sleeve steel plate, a main nail and a forcing screw, wherein a locking device is arranged between the main nail and the sleeve steel plate, and the locking device integrates the main nail and the sleeve steel plate of the goose head nail and changes the sliding state of the main nail and the sleeve steel plate into a locking state. The goose head nail is used for open reduction and fixation in a comminuted femur intertrochanteric fracture operation and can maintain the length of the neck of femur and the stability of the fracture fragments so as to avoid postoperative deformity, the healing is fast and good, and the perfection of the hip joint function of the patient can be maintained.
Description
Technical field:
This utility model belongs to medical apparatus and instruments, relates in particular to fixed apparatus in the bone surgery.
Background technology:
Intertrochanteric fracture of the femur is comparatively common clinically, and advanced at present Therapeutic Method is to adopt the open reduction internal fixation, generally uses Richard " s screw to fix.The intertrochanteric fracture of the femur that do not pulverize for having obviously, the bone piece is complete, therapeutic effect is sure.But because used gooseneck boom nail has the slip effect, when treatment femoral intertrochanteric comminuted fracture, because the fracture end sclerotin is cracked, lacking effective sclerotin supports, the main nail of gooseneck boom nail easily takes place to be withdrawed from from cover copper steel plate, the phenomenon that sclerite displacement, neck of femur cripetura or collodiaphyseal angle reduce, thus make fracture end generation malunion or disunion and cause operative failure, cause patient's hip joint function obstacle, have a strong impact on its work and life.
The utility model content:
It is good that the purpose of this utility model provides a kind of healing effect, is used for the gooseneck boom nail of comminuted intertrochanteric fracture of the femur open reduction internal fixation.
Locking-type gooseneck boom nail of the present utility model comprises sleeve steel plate, main nail, forcing screw; The sleeve steel plate is the gooseneck boom formula, comprises steel plate part and sleeve part; Main ailing head has screw thread, and main ailing tail has female thread, forcing screw and main ailing tail screw-internal thread fit; Locking-type gooseneck boom nail of the present utility model has locking device between main nail and the sleeve steel plate.
Described locking device is: the part that the nut of forcing screw contacts with the sleeve steel plate is a thread matching structure, and the nut of forcing screw has screw thread, and the sleeve-port of the sleeve steel plate that contacts with the nut of forcing screw has female thread.
Locking-type gooseneck boom of the present utility model nail make the nut of forcing screw and the sleeve-port of the sleeve steel plate that contacts with the nut of forcing screw between become thread matching structure, this structure has formed the locking device between main nail and the sleeve steel plate, this locking device makes the main nail of gooseneck boom nail become one with the sleeve steel plate, and sliding mode original between the two is become lock-out state.The open reduction that gooseneck boom nail of the present utility model is used for comminuted intertrochanteric fracture of the femur operation is fixed, and can keep the length of neck of femur and stablizing of sclerite, has avoided the odd-shaped generation of postoperative, and it is faster and better to heal, and can keep the intact of patient's hip joint function.
Description of drawings:
Fig. 1 is a locking-type gooseneck boom pin structure sketch map.
Fig. 2 is main nail of locking-type gooseneck boom nail and forcing screw structural representation.
Fig. 3 is the fixing sketch map of open reduction of comminuted intertrochanteric fracture of the femur operation.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, locking-type gooseneck boom nail comprises sleeve steel plate 1, main nail 2, forcing screw 3.The sleeve steel plate is the gooseneck boom shape, comprises sleeve part 4 and steel plate part 5, and main ailing head has screw thread 6.As shown in Figure 2, main ailing tail has female thread 7, and the screw thread 8 of forcing screw 3 matches with main ailing tail female thread 7.
As shown in Figure 1, locking-type gooseneck boom nail of the present utility model has screw thread 9 on the nut of forcing screw, and what cooperate with it is the female thread 10 at the sleeve-port place on the contacted with it sleeve steel plate.
As shown in Figure 3, locking-type gooseneck boom nail is to the fixing sketch map of the open reduction of comminuted intertrochanteric fracture of the femur operation, 11 is sclerite, because the threads engaged between the screw thread 9 on the forcing screw nut and the female thread 10 at sleeve steel plate upper bush mouth place forms locking device, the winner is followed closely with the sleeve steel plate form one, eliminated the dynamic pressurization of sliding and producing because of main nail, main nail can outwards not withdraw from from sleeve, sclerite can not squeezed and is shifted, neck of femur can keep length, the postoperative healing is faster and better, and patient's hip joint function can remain intact.
