Description
Technical Field
The utility model belongs to the technical field of medical instrument, specifically indicate an orthopedics internal fixation instrument.
Background
Metacarpophalangeal fracture is a common clinical fracture, the incidence rate is high, and displaced metacarpophalangeal fracture is usually required to be treated by an operation. The steel plate internal fixation can provide good biomechanical effect, but the operation wound is large, the cost is high, the steel plate needs to be taken out by secondary operation, and the incidence rate of joint adhesion and functional activity limitation is high. The kirschner wire can be fixed to reduce the fracture in a closed manner, and the kirschner wire is pulled out from the tail part of the kirschner wire reserved outside the body after the fracture is healed, so that the secondary hospitalization operation is avoided. However, the traditional kirschner wire needs to be driven by an electric drill, the direction is not easy to control, the reduction of the fracture is not easy to maintain, the kirschner wire is difficult to embed into the skin and take out in the later period, and the fixation failure of the kirschner wire can occur. The technical scheme designs a palm and finger bone internal fixation instrument which is convenient to use.
SUMMERY OF THE UTILITY MODEL
In order to solve the existing difficult problems, the utility model provides an internal fixation instrument for orthopedics department, which can save time effectively, reduce the operation difficulty and risk, improve the operation effect, and has high practicability, simple operation and low cost.
The utility model adopts the following technical scheme: the utility model relates to an orthopedics internal fixation instrument, including somatic part, point portion and afterbody, the somatic part is cylindrical setting, point portion is the rhombus setting, somatic part one end is located to point portion rigid coupling, does benefit to and breaks through the sclerotin, the afterbody is hexagonal prism setting, does benefit to the operator handheld, the one end of keeping away from point portion on the somatic part is located to the afterbody rigid coupling, be equipped with anti-skidding line on the afterbody lateral wall, the rigid coupling is equipped with the scale mark on the somatic part lateral wall.
Further, the diameter of the body is 1.0-2.0 mm.
Further, the body has a length of 30-100 mm.
Further, afterbody length is 20mm, the length of afterbody end to afterbody end is 15mm, and the afterbody of being convenient for is handled after the operation, and not amazing skin remains in vitro, makes things convenient for the later stage fracture healing back secondary to take out simultaneously.
Furthermore, the specification of the orthopedic internal fixation instrument is set according to the body diameter of every 0.2mm, so that the orthopedic internal fixation instrument is suitable for the bone mass and length and width of patients with different physiques.
Furthermore, the specification of the orthopedic internal fixation instrument is set to be one according to the length of the body part of the orthopedic internal fixation instrument per 10mm, so that the direction and the depth can be controlled by an operator conveniently.
Further, the body is made of a solid titanium alloy material.
Furthermore, the tail part is made of a plastic material.
Adopt above-mentioned structure the utility model discloses the beneficial effect who gains as follows: the orthopedic internal fixation instrument can be greatly convenient for an operator to use in the internal fixation of metacarpophalangeal fractures, is convenient and quick, is easy to operate, saves the operation time, improves the operation effect, and reduces the operation difficulty and risk; an electric drill is not needed, so that resources are saved; the utility model is convenient for the second time taking out, no scar is left, and the satisfaction of the patient is high.
