Locking-type bone fracture plate

Abstract

The invention provides a locking-type bone fracture plate. The locking-type bone fracture plate comprises a first stop block, a second stop block, a first traction rope and a second traction rope; thefirst stop block is provided with a first through hole and a second through hole at intervals; the second stop block is provided with a third through hole, a fourth through hole, a fifth through holeand a sixth through hole at intervals; the front end and the rear end of the second traction rope pass through the first through hole and the second through hole respectively, and the front end of the second traction rope passes through the fourth through hole after passing through the first stop block; and the rear end of the second traction rope passes through the third through hole after passing through the first stop block. During surgery, the second stop block can be moved towards a shoulder blade by drawing the second traction rope; the second traction rope only has friction with the side wall of the first through hole and the side wall of the second through hole, so that generated friction is relatively small; neither the first traction rope nor the second traction rope can be fractured; the operation is simple; the difficulty of the surgery is lowered.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a locking bone plate. Background technique [0002] Recurrent shoulder dislocation refers to the failure to repair the damaged joint capsule and labrum in time after the first trauma, so that the patient's accidental movements in daily life lead to repeated dislocation of the shoulder joint; therefore, how to treat recurrent shoulder dislocation has become a research topic. hotspots. [0003] In the prior art, part of the bone fragment is often cut from the coracoid process of the patient, and then the bone fragment is fixed on the scapula outside the labrum of the patient through a locking bone plate. The bone fragment can prevent the spherical articular cartilage from detaching from the labrum. This prevents shoulder dislocation. The locking bone plate includes: a first stop plate, a second stop plate and a traction rope; the first stop plate is usually in the sha...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the present invention provides a locking bone plate to solve the problem of the pulling rope when the front and rear ends of the pulling rope are pulled to drive the second stop plate to move towards the first stop plate in the prior art. The increase of the pulling force increases the friction between the traction rope and the side walls of all the through holes. Under the friction of the side walls of each through hole, the traction rope is easy to break, and the technical problem is that the operation is difficult.
