Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a bone marrow supporting device. The bone marrow supporting device comprises a drum-shaped supporting body, the thickness of the drum wall of the supporting body is 0.3-0.6 mm, rhombic through holes are evenly distributed in the drum wall of the supporting body, and an expanding and retracting mechanism is further arranged inside a drum of the supporting body and used for regulating the diameter of the supporting body. In comminuted fracture operation, the supporting device is put into the bone fracture position, the upper end of the supporting body is linked with the bone at the upper end of the bone fracture position, bone pieces caused by comminuted fracture are fixed to the peripheral face of the supporting body, bone marrow is put into a hollow cavity of the supporting body and will not be lost, and the completeness of the bone marrow is guaranteed; the through holes are formed in the drum wall of the supporting body, the bone marrow inside the supporting body can be connected with the bone pieces on the peripheral face, in this way, bone growth and bone piece healing are promoted, bone regeneration is rapid, the recovery period is shortened, and the recovery effect is good.

Description

Technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a bone marrow support device. Background technique [0002] Fracture accidents are currently on the rise, and surgical bone treatment is the most important treatment for fractures. For comminuted fractures, due to the relatively large number of fractures, it is difficult to fix the fracture position with a fixed plate in the prior art, and the bone marrow in the bone cavity is also easily lost, resulting in slow bone regeneration and a long recovery period for patients , The recovery effect is not good. Summary of the invention [0003] The purpose of the present invention is to provide a bone marrow support device, which is used for collecting bone marrow on the one hand and supporting broken bones on the other hand to facilitate the operation of bone surgery. [0004] In order to solve the above technical problems, a technical solution adopted by the present inventi...
