Problems solved by technology

[0003] 1. No structural consideration is given to avoiding the claw-shaped arm at the fracture site. If there is a claw-shaped arm at the fracture or crushed site, it will cause re-injury of the injured part of the arm, or cause the grasping of the broken end of the bone Compression causes deformed bones to grow;
[0004] 2. Due to the presence of end teeth at both ends of the main beam, the end teeth penetrate into the periosteum, making it difficult to remove the bone plate in the future, and will cause re-injury of the bone

Embodiment Construction

[0016] Referring to the accompanying drawings, the rib shape memory encircling bone plate in the figure is composed of a beam 1 and several identical encircling claws 2 integrated with the beam; the feature is that the encircling claws 2 are divided into left and right groups, and each The spacing a between the surrounding claws is equal, and the distance b between the two groups of surrounding claws in the middle section of the beam is 2-8 times the distance a between the surrounding claws in each group of surrounding claws.

[0017] In the above structure, the beam 1 is an arc beam with a radian of 10°-30°. There are 2-6 embracing claws in each group. The claw tip of the embracing claw 2 is arc-shaped, so as to effectively avoid the intercostal nerve during installation and avoid the pain caused by the compression of the intercostal nerve.

[0018] Both ends of the beam 1 have concave notches 3 .

[0019] The above-mentioned structure is used in this way--put the present i...

Abstract

The invention relates to a rib-shaped memory embracing bone plate consisting of a cross beam and a plurality of identical embracing claws which are integrated with the cross beam into a whole. The rib-shaped memory embracing bone plate is characterized in that the embracing claws are divided into a left group and a right group, the spacing interval between the embracing claws in each group is equivalent, and the distance between the two groups of the embracing claws at the middle section of the cross beam is 2-8 times of the spacing interval between the embracing claws in each group of the embracing claws. As the structure, the rib-shaped memory embracing bone plate can effectively avoid the rib fracture and the injuries, and the removal of the rib-shaped memory embracing bone plate after the operation is very convenient, thereby leading the operation treatment to be more secure and effective and effectively improving the survival quality of a patient.

Description

technical field [0001] The invention relates to a medical implantable surgical positioning or reset device, in particular to a rib shape memory encircling bone plate used for rib fracture connection or thorax reconstruction after rib cutting. Background technique [0002] In the operation of rib fracture connection or thoracic reconstruction after rib cutting, rib bone plate is often used. Through surgical implantation, the bone plate is fixed on the rib fracture by holding claws. After the fracture heals, the bone set is removed by surgery. plate. Patent No. 200620071652.5 discloses a memory alloy claw-shaped bone plate for ribs, which includes a main beam and connecting claw-shaped arms on both sides of the main beam. The main beam is arc-shaped, and end teeth are formed on both ends. Due to the described structure, this bone plate mainly has the following two problems: [0003] 1. No structural consideration is given to avoiding the claw-shaped arms at the fracture site...
