Abstract
The invention discloses a locking plate type intramedullary nail for femoral intertrochanteric fracture treatment. The locking plate type intramedullary nail for femoral intertrochanteric fracture treatment is made of a titanium-nickel alloy and comprises a longitudinal nail, a transverse nail and a locking plate. The transverse nail comprises a head portion, a body portion and a tail portion. The head portion is conical, the body portion is cylindrical, the tail portion is provided with a hexagonal recess, an external thread is arranged from the middle portion of the body portion to the head portion, and the head portion, the body portion and tail portion are connected as a whole. The outer side surface of the transverse nail is designed with a groove, the center line of the groove and the center line of the transverse nail are on different surfaces, and the locking plate is inserted into the groove. The transverse nail and the longitudinal nail are in intersection. When the locking plate type intramedullary nail for femoral intertrochanteric fracture treatment is used in an operation, a fracture is reduced and drilled, the longitudinal nail penetrates the fracture, the transverse nail is screwed in the longitudinal nail, and the locking plate is inserted into the groove. The locking plate type intramedullary nail for femoral intertrochanteric fracture treatment avoids the Z effect of a traditional nail, can slide with load within a controllable range, greatly reduces the size, reduces the bone loss and avoids the swinging of the intramedullary nail.
Description
Technical field
The present invention relates to a kind of sheet type intramedullary pin being used for the treatment of intertrochanteric fracture of the femur of hospital orthopedics.
Background technology
Fracture of femur case is a lot of clinically, and have neck of femur substrate to fracture, greater trochanter and little intertrochanteric fracture, fracture under greater trochanter, ipsilateral femoral near-end, fracture of shaft of femur, and tumor and pathologisch Bruch sickness rate improve year by year.All adopt the mode of femoral interlocking nail internal fixtion to treatment femur and intercondylar fracture of the femur clinically, Medullary fixation meets biomechanical theory, fixation, can early functional exercise, and early loading, prevents the cripetura of bone, avoids the axis of fracturing and rotation deformity.Background technology the most close with the present invention in prior art is number of patent application: 201020616039.3, Authorization Notice No.: CN201861740U.
Weak point is: clinical manipulation is not very convenient, and volume ambassador bone-loss is comparatively large, easily outwards loosens.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of sheet type intramedullary pin being used for the treatment of intertrochanteric fracture of the femur, it is made to facilitate clinical manipulation, reduce bone mass loss, the Z effect avoiding the rotation of intramedullary pin and tradition nail to produce, can provide controllable slip pressure effect to reduce the growth stress of osseous tissue.
For solving the problems of the technologies described above, the technical problem that the present invention mainly solves is to provide a kind of sheet type intramedullary pin being used for the treatment of intertrochanteric fracture of the femur, and material is Ti-Ni alloy, and it comprises: longitudinally nail, laterally nail and locking plate; Described laterally nail lateral surface is designed with a groove; Described locking plate interts in a groove; Described laterally nail passes through mutually with longitudinal nail, interts in longitudinally following closely; Described laterally nail comprises: head, body and afterbody, and described head, body and afterbody are connected, and described horizontal nail head is cone shape, and described body is cylindric, and described afterbody has a hexagon indent, cause head and be provided with external screw thread in the middle of described body; The centrage of described groove follows closely centrage antarafacial with horizontal; Described channel section is one trapezoidal, and opening is trapezoidal upper base; Described locking plate cross section is also one trapezoidal, and trapezoidal bottom surface and groove bottom surface match.
The invention has the beneficial effects as follows: can clinical manipulation be facilitated, reduce bone mass loss, avoid rotation and the Z effect of intramedullary pin, controllable slip pressure effect can be provided, the stress that bone growth produces can be reduced.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Embodiments of the invention as Figure 1-3, a kind of sheet type intramedullary pin being used for the treatment of intertrochanteric fracture of the femur, material is Ti-Ni alloy, and it comprises: longitudinally nail 1, laterally nail 2 and locking plate 3; Described laterally nail 2 lateral surface are designed with a groove 4; Described locking plate 3 interts in groove 4; Described laterally nail 2 with longitudinally follow closely 1 and passes through mutually, laterally nail 2 interts and follows closely in 1 longitudinal; Described laterally nail 2 comprises: head 5, body 6 and afterbody 7, described head 5, body 6 and afterbody 7 are connected, and described laterally nail 2 head 5 is in cone shape, and described body 6 is in cylindric, described afterbody 7 has a hexagon indent 8, causes head 5 and be provided with external screw thread 9 in the middle of described body 6; Described groove center line 10 follows closely centrage 11 antarafacial with horizontal; Described groove 4 cross section is one trapezoidal, and opening is trapezoidal upper base; Described locking plate 3 cross section is also one trapezoidal, and trapezoidal bottom surface and groove 4 bottom surface match.
The work process being used for the treatment of the sheet type intramedullary pin of intertrochanteric fracture of the femur of the present invention is as follows:
In fig. 1-3, during operation, reduction of the fracture boring is penetrated after longitudinally following closely 1, horizontal nail 2 is screwed in and longitudinally follows closely in 1, then locking plate 3 is interted in the groove 4 of horizontal nail 2, last suturing soft tissue.
