Description

Fracture reduction spreader

The technical field is as follows:

the invention belongs to the technical field of medical instrument manufacturing, and particularly relates to a fracture reduction distracter.

Background art:

fracture reduction is an important step for treating fracture by surgical operation, after trauma, the fracture end is shortened and displaced due to the traction of muscles at the two ends of fracture, and excessive muscle stripping at the two ends can influence the blood circulation at the fracture end and the healing of fracture. For fracture which is difficult to reduce, a steel plate is usually arranged in advance at one end, and a screw is also screwed at the other end to reduce the fracture by using a spreading clamp. As the contact points of the distraction forceps and the two ends of the fracture are not in the same plane after the shortening and the displacement, the contact between the distraction forceps and the two ends of the fracture is poor, and the distraction effect is influenced, so that the inventor knows that the problem is not solved at present and has related reports.

The invention content is as follows:

the invention aims to solve the defects, and provides the fracture reduction distracter which has simple and reasonable structural design and flexible and convenient use, one end of the distracting forceps is used for fracture reduction positioning, and the end in contact with a steel plate is provided with the universal rotating arm clamp, so that the distracting forceps can be in good contact with one end of the steel plate, two fracture ends are kept on the same horizontal line in the process of gradual distraction, the fracture reduction is gradually restored, the best fracture reduction is met, the fracture healing is accelerated, and the pain of a patient is relieved to the maximum extent.

The technical scheme is realized in such a way that the fracture reduction spreader is characterized in that a pair of pliers type reduction supporting pliers 1 is arranged, the reduction supporting pliers 1 is provided with a long handle and a short handle, the end of the long handle is vertically provided with a reduction rack 6 through a connecting shaft 5, a U-shaped spring clamp 4 is arranged between the long handle and the short handle, one side of the jaw of the reduction supporting pliers 1 is provided with a positioning clamp 2, the other side of the jaw of the reduction supporting pliers 1 is provided with a universal rotating arm clamp 3, and the end head of the short handle is provided with an inclined plane edge. The universal rotating arm card 3 that resets and support 1 pincers mouth one side and set up is being by dop 7, and swinging boom 8, swinging boom base 9 is constituteed, and swinging boom base 9 is connected in the one side that resets and support 1 pincers mouth, sets up swinging boom 8 in swinging boom base 9, sets up dop 7 at swinging boom 8 end.

The working principle is as follows: the two handles of the reduction support forceps 1 are utilized to prop open the two ends of the dislocation fracture, the inclined plane edge at the end of the short handle is clamped into the 5 teeth of the reduction rack vertically arranged at the end of the long handle, and the short handle is clamped under the action of the U-shaped spring clamp 4, and the reduction support forceps are specifically as follows: the screw fixation of one end of the fracture is realized by a positioning clamp 2 arranged on one side of a jaw of the reduction supporting forceps 1, the other side steel plate end of the dislocation fracture is clamped by a clamping groove connected with a universal rotating arm clamp 3 on the other side of the jaw of the reduction supporting forceps 1, the upper and lower directions of the other end of the fracture are adjusted by utilizing the characteristic of the left and right vertical rotation of the universal rotating arm clamp 3, the two fracture ends can be gradually spread, the inclined plane edge of the end of a short handle is adjusted to be clamped into the tooth position in the teeth of a reduction rack 5, and the two ends of the fracture are gradually, stably and accurately butted and reset.

Compared with the prior art, the invention has the advantages that the screw at one end of the fracture is fixed by the jaw positioning clamp 2 of the reduction supporting clamp 1, the butt joint direction of the other end of the fracture is adjusted by the universal rotating arm clamp 3 of the jaw of the reduction supporting clamp 1, the spreader can be well contacted with the steel plate, the defect that the clamping groove and the screw are not in the same plane due to the short displacement is completely avoided, the contact adaptability of the spreader and the steel plate is increased, the accurate reduction of the fracture is realized, the labor intensity of medical staff is reduced, the pain of a patient is relieved, the reduction time is shortened, the reduction accuracy is improved, and the reduction quality is realized.

Description of the drawings:

FIG. 1 is a view showing the structure of the present invention

FIG. 2 is a structural diagram of a universal rotary arm card according to the present invention
