Embodiment 1

[0029] A bone marrow extraction device for hematology, such as Figure 1 to Figure 4 As shown, it includes a mounting assembly 1 , a drilling assembly 2 and a power assembly 3 , the mounting assembly 1 is provided with the drilling assembly 2 , and the mounting assembly 1 is provided with the power assembly 3 .

[0030] When bone marrow extraction is required, the installation component 1 is controlled to fix the device, and then the power component 3 is controlled to make the drilling component 2 operate, so that the drilling component 2 enters the bone marrow, and then the bone marrow can be extracted, and the extraction is completed Then control the reverse operation of the power assembly 3, so that the drilling assembly 2 can be reversed and reset.

[0031] Mounting assembly 1 comprises mounting plate 101, concave plate 102, support 103, fixed plate 104 and telescoping tube 105, the rear side of mounting plate 101 is connected with concave plate 102, and the upper side of ...

Embodiment 2

[0038] On the basis of Example 1, such as figure 1 , Figure 5 , Figure 6 , Figure 7 with Figure 8 As shown, an opening assembly 4 is also included. The opening assembly 4 includes a communication pipe 401, a lower drill bit 402, a suction pipe 403 and a compression spring 404. The middle part of the screw rod 202 is slidably connected to the communication pipe 401, and the lower side of the communication pipe 401 is connected to There is a lower drill bit 402, the lower drill bit 402 cooperates with the drill bit body 203, four suction pipes 403 are evenly spaced at the bottom of the connecting pipe 401, a compression spring 404 is connected between the connecting pipe 401 and the screw mandrel 202, and the drill bit body 203 is evenly spaced. There are four installation grooves 405 at intervals, and the installation grooves 405 cooperate with the suction pipe 403 .

[0039] Control the rotation of the hand wheel 303, which will make the screw mandrel 202 and the drill...

Abstract

The invention relates to an extraction device, in particular to a bone marrow extraction device for the hematology department. The technical problem to be solved by the invention is to provide the bone marrow extraction device for the hematology department, which is simple and convenient to operate. The bone marrow extraction device for the hematology department comprises a mounting assembly, a drilling assembly mounted on the mounting assembly, and a power assembly mounted on the mounting assembly. The device is provided with the opening assembly, bone marrow can be extracted through the suction pipe and the communicating pipe, then the bone marrow can be extracted without replacing an extraction device, and then the pain of a bone marrow extractor is relieved; the device is provided with the extraction assembly, and the piston rod can be controlled to move, so that a worker can conveniently extract bone marrow and collect the extracted bone marrow; the device is provided with the pressing assembly, so that the device automatically drives the pressing rod to move downwards, a worker does not need to manually control the pressing rod to move downwards to extract bone marrow, and the operation trouble of the worker is reduced.

Description

technical field [0001] The invention relates to an extraction device, in particular to a bone marrow extraction device for hematology. Background technique [0002] Bone marrow exists in the cancellous cavity of bone and the marrow cavity of long bones. It is composed of various types of cells and reticular connective tissue. According to its structure, it is divided into red bone marrow and yellow bone marrow. It is a soft tissue rich in blood. [0003] When extracting bone marrow, it is necessary to use a punching device to pierce the bone, and then replace the bone marrow extraction device to take out the bone marrow. The pain of the patient increases, and the difficulty of the operation increases, which may easily lead to inaccurate surgery, and the recovery time of the bone marrow extractor is longer after the operation. [0004] Therefore need to design a kind of bone marrow extracting device that is simple and convenient to operate for internal medicine. Contents o...
