Problems solved by technology
[0003] Clinically, when orthopedic surgeons fix the fractured part of the patient, the doctor usually drills a hole at the joint of the bone with an electric drill, and then requires the doctor to hold the Kirschner wire with one hand, and smash the Kirschner wire into the hole with the other hand using a hammer , Sometimes it may cause damage to the patient's bone due to excessive force. At the same time, the Kirschner wire is longer, which can easily cause the Kirschner wire to bend, which will increase the patient's pain and increase the doctor's work pressure.

The front end of the push rod passes through the connector and is connected with a chuck for clamping the Kirschner wire. The pressure handle on the frame, and one end of the pressure handle is provided with a linkage shaft, and the linkage shaft is relatively set against the driving plate. The limit unit includes a limit spring and a limit piece, and the front end of the syringe is connected with an end cover. The end face of the end cover is provided with a conical head integrated with the end cover, and a cylindrical hole is arranged in the conical head, and a guide sleeve is detachably installed in the end cover. guide.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an orthopedic Kirschner wire propeller. Background technique [0002] Kirschner wire is a commonly used internal fixation material in orthopedics. Its original size is generally fixed at about 20 cm, and there are several different sizes with a diameter of 0.5-2 mm. It is used to fix stress such as short fractures or avulsion fractures. Small fracture fixation is also often used in the fixation of temporary fracture fragments in orthopedic surgery. [0003] Clinically, when orthopedic surgeons fix the fractured part of the patient, the doctor usually drills a hole at the joint of the bone with an electric drill, and then requires the doctor to hold the Kirschner wire with one hand, and smash the Kirschner wire into the hole with the other hand using a hammer , sometimes may cause damage to the patient's bone due to excessive force, and the Kirschner wire is longer, which...
