Description

Technical Field

[0001] The utility model relates to the technical field of cells, and specifically relates to a cell anti-loosening sampling device. Background Art

[0002] Cells are the basic structural and functional units of organisms. With the continuous development of technology, it has greatly improved the medical industry, and diagnoses and treats diseases in patients' affected areas through high-tech means.

[0003] Most of the existing cell sampling of the adhesive film is completed with medical tweezers. Since the volume of the sampled cell samples for the clamping sampling work is usually small, when moving the tweezers, it is easy to cause the sample to fall off due to a slight change in the hand grip force. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cell anti-loosening sampling device to overcome the above-mentioned defects in the prior art.

[0005] According to a cell anti-loosening sampling device of the utility model, it includes a frame. Two rotating top frames are symmetrically and rotatably arranged on the left and right of the lower end surface of the frame. A dismounting bottom frame is fixedly arranged on the lower end surface of the rotating top frame, and the dismounting bottom frame is detachably connected to the rotating top frame.

[0006] A lifting cavity communicating front and back is arranged inside the frame. A lifting block capable of moving up and down is arranged in the lifting cavity. Lifting connecting columns are fixedly arranged on the front and back end surfaces of the lifting block. A connecting rotating shaft is rotatably arranged on the end surface of the rotating top frame far from the center.

[0007] In some embodiments, a lifting moving shaft is rotatably arranged in the lifting cavity. The outer circumferential surface of the lifting moving shaft is threadedly connected to the lifting block. A lifting motor is fixedly arranged on the upper wall of the lifting cavity, and the upper end surface of the lifting moving shaft is power-connected to the lifting motor.

[0008] In some embodiments, a clamping head is fixedly arranged on the lower end surface of the dismounting bottom frame. The clamping head is hemispherical and can clamp cell samples.

[0009] In some embodiments, connecting rods are rotatably connected between the front and back sides of the outer circumferential surface of the connecting rotating shaft and the outer circumferential surface of the lifting connecting column on the same side.

[0010] In some embodiments, connecting springs are fixedly connected between the left and right end surfaces of the frame and the end surfaces of the rotating top frame on the same side close to the frame.

[0011] In some embodiments, a lighting lamp is fixedly arranged on the lower end surface of the frame, and the lighting lamp can play a lighting role.

[0012] In some embodiments, a grip rod is fixedly provided on the right end face of the frame, and a control panel is fixedly provided on the right end face of the frame. The control panel can control the start and stop of all motors of the present utility model.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] 1. The present utility model relies on a motor to provide power for clamping work. After sampling, the lifting motor does not start again, so that the clamping heads on both sides are fixed at the same position. When the frame moves with the sample clamped, the disassembly chassis and the clamping heads will not shake due to the change of the gripping force, so as to avoid the situation of the sample falling.

[0015] 2. The present utility model illuminates the cell components to be clamped and sampled by starting the lighting lamp, ensuring that the staff can quickly and accurately locate the sampling point. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1

[0026] Refer to Figures 1 - 6 , which is the first embodiment of the present invention. This embodiment provides an embodiment of a cell anti-loosening sampling device, including a frame 11. Two rotating top frames 20 are symmetrically and rotatably arranged on the left and right of the lower end surface of the frame 11. A disassembly bottom frame 18 is fixedly arranged on the lower end surface of the rotating top frame 20. The disassembly bottom frame 18 is detachably connected to the rotating top frame 20.

[0027] There is a vertically communicating lifting cavity 14 inside the frame 11. A lifting block 17 that can move up and down is arranged in the lifting cavity 14. Lifting connection columns 16 are fixedly arranged on the front and rear end surfaces of the lifting block 17. A connecting rotating shaft 22 is rotatably arranged on the end surface of the rotating top frame 20 away from the center.

[0028] A lifting moving shaft 15 is rotatably arranged in the lifting cavity 14. The outer circumferential surface of the lifting moving shaft 15 is threadedly connected to the lifting block 17. A lifting motor 25 is fixedly arranged on the upper wall of the lifting cavity 14. The upper end surface of the lifting moving shaft 15 is power-connected to the lifting motor 25.

[0029] A clamping head 19 is fixedly arranged on the lower end surface of the disassembly bottom frame 18. The clamping head 19 is hemispherical and can clamp cell samples.

[0030] A connecting rod 21 is rotatably connected between the outer circumferential surfaces on the front and rear sides of the connecting rotating shaft 22 and the outer circumferential surface of the same-side lifting connection column 16.

[0031] A connecting spring 23 is fixedly connected between the left and right end surfaces of the frame 11 and the end surface of the same-side rotating top frame 20 close to the frame 11.

[0032] A lighting lamp 24 is fixedly arranged on the lower end surface of the frame 11. The lighting lamp 24 can play a lighting role.

[0033] A grip rod 12 is fixedly arranged on the right end surface of the frame 11. A control panel 13 is fixedly arranged on the right end surface of the frame 11. The control panel 13 can play a role in controlling the start and stop of all motors of the present invention.

[0034] Specific working process:

[0035] When performing the clamping operation, the lighting lamp 24 can be activated to illuminate the cell components to be clamped and sampled, ensuring that the staff can quickly and accurately locate the sampling points.

[0036] After the clamping head 19 moves to the sampling area, the lifting motor 25 can be activated to drive the lifting moving shaft 15 to rotate, thereby driving the lifting block 17 and the lifting connecting column 16 to move upward slowly, and then driving the connecting rod 21 to start rotating around the lifting connecting column 16, so that the two rotating top frames 20 start to move towards the center side, and thus the two dismounting bottom frames 18 and the clamping head 19 start to rotate towards the center and sample the cell components. The clamping operation of the present utility model relies on the motor to provide power. After sampling, the lifting motor 25 is no longer activated, so that the two clamping heads 19 are fixed at the same position. When the rack 11 moves with the sample, the dismounting bottom frame 18 and the clamping head 19 will not shake due to the change of the gripping force, so as to avoid the situation of the sample falling.

[0037] The above are only specific embodiments of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
