Platelet-rich plasma and bone powder collecting and separating device in operation

Abstract

The invention discloses a platelet-rich plasma and bone powder collecting and separating device in operation, which belongs to the technical field of mechanical apparatus. The device comprises a barrel body and a barrel cover which are installed together inside a centrifuge; a clapboard is fixedly installed inside the barrel body to divide the barrel body into an upper cavity and a lower cavity; inclined confluence channels communicated with the upper cavity are arranged on the clapboard; the confluence channels are arranged in the lower cavity and are converged in a powder collector; annularly arranged barrier walls are arranged on the clapboard; the barrier walls are integrated with the barrel cover in a sealing manner and are located on the periphery of the confluence channels; and an air exhausting channel and a blood input channel, both of which are communicated with the upper cavity, are arranged on the barrel cover. The platelet-rich plasma and bone powder collecting and separating device in operation provided by the invention solves the technical problem that useful substances such as blood and bone powder run off in operation, which is unable to recycle effective components thereof and is bad for fracture healing of patients. And the platelet-rich plasma and bone powder collecting and separating device in operation provided by the invention is widely applied to orthopedic operation processes.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for collecting and separating platelet-rich plasma and bone powder during operation. Background technique [0002] In the clinical operation process, the most commonly used treatment method for fracture patients in the orthopedics department of the hospital is to perform open reduction and internal fixation of fractures. The skin of the affected area is cut open. After a large amount of blood loss, first reset the displaced fracture end or close to the original normal position, then implant a steel plate at the fracture site, and use a drill to drill holes in the bone. Bone powder will be produced during the drilling process. , A steel nail is screwed behind the drilled channel to fix the steel plate to the bone. During the drilling process, a mixture of autologous bone powder and blood will be continuously produced, and bone powder and blood are generally lost t...
