Abstract

The invention discloses a device for bone marrow puncture of a patient after hematopoietic stem cell transplantation and a puncture method. The device comprises a housing, a positioning seat is fixedly connected to the right side of the housing, a fixed handle is fixedly connected to the front surface of the positioning seat, a movable handle is movably connected to the front surface of the fixedhandle, a reset spring is movably connected between the fixed handle and the movable handle, a push block is movably connected to the left end of the movable handle, a limited seat is fixedly connected to the left side of the housing, the front surface of the limited seat is movably connected with a top block, the lower part of the top block is movably connected with a limited elastic sheet, and can be matched by a stroke scale and stroke scales, the movement stroke of the puncture needle push rod can be instructed to ensure the penetration depth accuracy of a puncture needle, safety and accuracy during operation can be improved, and patient safety is ensured while reducing the risk of a surgery.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a device and a puncture method for bone marrow puncture of a patient after hematopoietic stem cell transplantation. Background technique [0002] Hematopoietic stem cell transplantation is a process in which patients first receive ultra-high doses of radiotherapy or chemotherapy (usually lethal doses of radiotherapy and chemotherapy), sometimes in combination with other immunosuppressive drugs to remove tumor cells and abnormal clone cells in the body, and then reinfuse them from themselves or others Hematopoietic stem cells, a therapeutic means to rebuild normal hematopoietic and immune function. [0003] In order to evaluate the patient's physical condition and rehabilitation after transplantation, and also to monitor the effect of transplantation, it is necessary to detect the microcirculation environment of the patient's bone marrow after bone marrow transplantation...
