A device for assisting bone marrow puncture biopsy for blood clinical use

Abstract

This invention discloses an auxiliary device for bone marrow aspiration biopsy in clinical blood testing, relating to the field of medical device technology. It includes a base with sliding grooves on both sides, a support frame slidably connected within the sliding grooves, a limit sensor mounted on the support frame, a drive motor mounted on the support frame via a motor bracket, and a screw connected to the output end of the drive motor via a coupling; and a positioning component. Through its designed positioning component, during bone marrow aspiration biopsy, when the drive motor drives the screw to precisely raise and lower the sliding block to the target height, the positioning component is synergistically adjusted by an angle adjustment rod and a lifting support rod, thereby precisely aligning the puncture target point marked by the laser emitter with the guide hole. This ensures that the infrared rangefinder and PLC controller can monitor and calibrate in real time during the puncture operation, greatly improving the success rate and safety of clinical punctures.
