Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to medical instrument technical field especially relates to a short wide type distal radius steel plate. BACKGROUND
[0002] The steel plate is one of the most widely used consumables in orthopedic surgery, and is usually used for internal fixation of fracture. Distal radius fracture is one of the most common fractures, and most of the distal radius fractures need to be internally fixed with a steel plate. Since the distal radius fracture is a fracture within 3 cm from the articular surface, the bony structure of the distal radius is flat and trumpet-shaped, and the position of the screw is relatively wide, so the screws near the fracture line can be arranged in two rows, both of which are located on both sides of the medullary cavity close to the cortex. In addition, patients do not need to exercise during the fracture healing period after surgery, so the mechanical requirements of the steel plate are different from the lower limb fracture steel plate which requires strong strength and length, and there is no need to lengthen the steel plate to avoid stress concentration leading to steel plate screw fracture. In clinical practice, studies have shown that the surgical plan using a transverse incision on the palm of the wrist during surgery is more conducive to the recovery of the incision of the patient, and also reduces the probability of postoperative infection of the patient, and the scar of the patient after recovery is smaller. In addition, this scheme also preserves the integrity of the pronator quadratus muscle of the patient, thereby effectively protecting the pronation function of the wrist joint of the patient, so that the patient can recover the wrist joint function earlier and shorten the recovery time of the patient.
[0003] In the prior art, the steel plate used in the distal radius fracture is relatively long, and a large surgical field is required during surgery, which is not suitable for the transverse incision scheme. The use of a long steel plate during surgery often requires the pronator quadratus muscle of the patient to be cut off, although the pronator quadratus muscle of the patient will be sutured and repaired after surgery, but the function of the pronator quadratus muscle of the patient cannot be restored to the state before cutting off. In addition, the precision of the long steel plate placed during surgery is low, and the steel plate may be deviated ulnarly or radially during placement, and the skill requirement of medical personnel is also high, which reduces the surgical efficiency.
