Abstract
The utility model relates to a Gama nail, which is provided with a hollow nail rod and a nail tail. The nail rod and the nail tail form an integral structure, two obliquely-crossed nail locking holes are formed on the nail tail, two nail locking holes are formed on the nail rod, and an included angle of 174 degrees to 176 degrees is formed between the nail rod and the nail tail. The Gama nail is reasonable and compact in structure, is corrosion-resisting, and enables an operation to be simple, quick, convenient and effective. With the Gama nail, as smaller incision only needs to be cut on a dermal bone in the operation, the operation time is shortened, the pain of a patient is reduced, the recovery after the operation is facilitated, and a medical treatment effect is improved.
Description
Technical field
This utility model relates to a kind of gamma nail, and especially a kind of fracture of shaft of femur, neck of femur and femoral shaft combination type fracture internal fixation of being applicable to implanted the gamma nail.
Background technology
Fracture of shaft of femur operation at present is that internal fixation is implanted as the standard gamma nail, adopts professional operating theater instruments to carry out standard femur locking mode.Neck of femur and femur during fracture operation, need to adopt another kind of special-purpose operating theater instruments to carry out the femur locking and rebuild locking with strand neck simultaneously, and the gamma nail is implanted to femoral bone cavitas medullaris, damages neck of femur easily even causes cracking.And need on osteoderm, open bigger otch, in the operation process time longer, bring unnecessary misery to the patient.After gamma was followed closely in the medullary cavity that is implanted in fracture patient, bone marrow marrow blood flow was not smooth, influences the healing of fracture portions.
The utility model content
The technical problem that this utility model will solve is: be irregular curved characteristic to skeleton, propose a kind of novel gamma nail that is fit to this characteristic, be suitable for the practice of human body orthopaedic medical treatment.After gamma was followed closely in the medullary cavity of implanting fracture patient, bone marrow marrow blood flow was not smooth, the fracture portions quickly-healing.
This utility model solves the technical scheme that its technical problem adopted: a kind of gamma nail; Have hollow nail bar and nail tail; Described nail bar is structure as a whole with the nail tail; Have two oblique locking nail holes on the described nail tail, have two locking nail holes on the described nail bar, described nail bar is 174 °-176 ° with the angle of nail tail.
Further, the described nail tail of this utility model has mechanical connection locating notch and mechanical connection screw.
The beneficial effect of this utility model is, rational in infrastructure, the compact conformation of this utility model, and corrosion resistance makes operation more simple, quick, effective.Owing to only need in the operation on osteoderm, to open less otch, can shorten operating time, can reduce the patient suffering, the back rehabilitation of being convenient to perform the operation improves medical effect.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Fig. 1 is the structural representation of this utility model.
Fig. 2 is the cutaway view of Fig. 1.
1. oblique pinnings among the figure, 2. locking nail hole, 3. mechanical connection locating notch, 4. mechanical connection spiral shell, 5. nail bar, 6. nail tail.
The specific embodiment
Combine accompanying drawing that this utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of this utility model only is described in a schematic way, so it only show the formation relevant with this utility model.
Like Fig. 1, the gamma of this utility model shown in Figure 2 nail has hollow nail bar 5 and nail tail 6, and nail bar 5 is structure as a whole with nail tail 6; Have two oblique locking nail holes 1 on the nail tail 6, have two locking nail holes 2 on the nail bar, improve the power pressurization; Nail bar 5 is 175 ° with the angle of nail tail 6; Be convenient to implant in the bone marrow pulp cavity, save the technology that enlarges intramedullary canal, the nail tail has mechanical connection locating notch and mechanical connection screw.
With above-mentioned desirable embodiment according to this utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the description, must confirm its technical scope according to the claim scope.
Claims (2)
