Memory alloy internal fixing instrument for anatomy locking of scapula coracoid area

Abstract

A memory alloy internal fixing instrument for anatomy locking of the scapula coracoid area is made of memory alloy, is a whole fracture-setting steel plate, is divided into four parts including a scapula mesoscapula part, a scapula acromion part, a joint bridging part and a scapula coracoid part, and is suitable for facture of the scapula coracoid part, the scapula mesoscapula part and the acromion part. The shape of the memory alloy internal fixing instrument is designed according to the physiological anatomy shape of the scapula coracoid part, the scapula mesoscapula part and the acromion part, and the memory alloy internal fixing instrument can connect and stereoscopically fix the scapula coracoid part, the scapula mesoscapula part and the scapula acromion part together. The memory alloy internal fixing instrument for anatomy locking of the scapula coracoid area is good in elasticity and strength and can be processed in a bent, twisted and sheared mode freely according to the fixation need of a fracture operation. In addition, the memory alloy internal fixing instrument is convenient to shape and install, external fixation is not needed after the operation, early function exercise of the shoulder joint is facilitated, and postoperative ankylosis is prevented. By means of the memory alloy internal fixing instrument, the curative effect is improved, complications are reduced, a complex operation is simplified, operation risks are reduced, and the memory alloy internal fixing instrument is worth popularization.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an internal fixation device made of memory alloy and used for fractures at the spine of the scapula, the acromion of the scapula, and the coracoid process of the scapula. Background technique [0002] With the development of the economy and the development of transportation, construction and other industries, scapula fractures have become increasingly common in recent years, accounting for 3% to 5% of shoulder fractures, close to 1% of systemic fractures, and coracoid process fractures accounted for 3% to 13% of scapula fractures. The complex anatomical relationship of the coracoid process makes it particularly important in the shoulder. Previous conservative treatment has a certain probability of causing sequelae such as shoulder joint instability and upper limb dysfunction after fracture healing. With the increasing requirements of patients on the quality of life, go...

Problems solved by technology

[0008] In the above-mentioned disclosed documents, some problems of scapula fractures can be solved, but there are disadvantages: the structure of the device is too simple, it cannot be locked with other parts close to the fracture site of the scapula, and the fixation of the device to the fracture site is not firm. Not ideal; and some structures are too complicated, complicated and cumbersome in the operation process, not very practical, and not many real applications

Due to the irregular position and complex anatomical structure, the surgical technique is difficult and risky, and the quality of surgical instruments and surgical methods can directly affect the treatment effect

The current traditional surgical methods and instruments can solve some problems, but the disadvantage is that the treatment effect is not ideal, and some new instruments that have appeared are not practical, so they are difficult to promote and use

[0010] At present, there is a lack of anatomical internal fixation devices that match the scapula, which increases the difficulty of the operation and directly affects the treatment effect
