[0024] The mounting base 2 is rotatably mounted between the two support plates 11. A transverse plate 21 is connected to the top and bottom ends of the mounting base 2 on the side away from the base 1. A fixed shaft is provided on the side wall of the base 1 near the mounting base 2. The fixed shaft passes through the mounting base 2 and is connected to the fixed gear 12. The fixed shaft is rotatably connected to the mounting base 2. A rotating shaft 22 is rotatably connected between the two transverse plates 21. The top end of the rotating shaft 22 passes through one of the transverse plates 21, and the bottom end of the rotating shaft 22 passes through the other transverse plate 21 and is connected to the output shaft of a driving member 23. The driving member 23 is provided on the transverse plate 21 and can drive the rotating shaft 22 to rotate back and forth.

[0025] The active seat 3 is rotatably connected to the horizontal plate 21 at the bottom end of the placement seat 2. A driven seat 4 is provided above the active seat 33. The top surface of the active seat 3 and the bottom surface of the driven seat 4 are both provided with placement grooves. The active seat 3 and the driven seat 4 can stably clamp the test tube (the test tube is used to hold adipose tissue). The top surface of the driven seat 4 is rotatably connected to a turntable 41. The top surface of the turntable 41 is fixedly connected to a sleeve 42. A driven shaft 43 is provided in the sleeve 42. The driven shaft 43 is rotatably connected to the horizontal plate 21 close to it, and the top end of the driven shaft 43 passes through the above-mentioned horizontal plate 21. The surface of the driven shaft 43 is provided with a first circulation groove (the first circulation groove is actually an arc-shaped groove body that surrounds the outer surface of the driven shaft 43 and is connected end to end). A guide column that can cooperate with the first circulation groove is provided on the inner wall of the sleeve 42. When the driven shaft 43 rotates unidirectionally, the sleeve 42 can drive the turntable 42 to rise and fall back and forth.

[0026] The first sleeve 5 is rotatably arranged on the top of the rotating shaft 22. A first ratchet is provided on the side wall of one end of the first sleeve 5. The first ratchet, the first sleeve 5 and the rotating shaft 22 are concentric. A first pawl that can rotate in one direction is rotatably provided on the rotating shaft 22. When the first ratchet and the first pawl cooperate, the rotating shaft 22 can drive the first sleeve 5 to rotate. A first belt 51 is provided between the first sleeve 5 and the driven shaft 43.

[0027] The second sleeve 6 is rotatably arranged at the bottom of the rotating shaft 22. A second ratchet is provided on the side wall of one end of the second sleeve 5. The second ratchet is opposite to the first ratchet. The second ratchet, the second sleeve 6 and the rotating shaft 22 are concentric. A second pawl that can rotate in one direction is rotatably provided on the rotating shaft 22. When the second ratchet and the second pawl cooperate, the rotating shaft 22 can drive the second sleeve 6 to rotate. A second belt 61 is provided between the second sleeve 5 and the active seat 3.

[0028] The third sleeve 7 is rotatably arranged in the middle of the rotating shaft 22. A third ratchet is provided on the side wall of one end of the third sleeve 7. The third ratchet is in the same direction as the second ratchet. The third ratchet, the third sleeve 7 and the rotating shaft 22 are concentric. A third pawl that can rotate in one direction is rotatably provided on the rotating shaft 22. A reciprocating seat 71 is provided on the third sleeve 7. A second circulation groove is provided on the surface of the third sleeve 7 (the second circulation groove is similar in structure to the first circulation groove). The reciprocating seat 71 cooperates with the second circulation groove (the cooperation method of the reciprocating seat 71 and the second circulation groove refers to the sleeve 42 and the first circulation groove). The reciprocating seat 71 is provided with a rack 72 that can mesh with the fixed gear 12. When the reciprocating seat 71 performs reciprocating lifting motion, it can drive the placement seat 2 as a whole to rotate back and forth within a certain angle.

[0029] See also Figures 1 to 4 Preferably, a plurality of limiting rods 73 passing through the reciprocating seat 71 are provided beside the rotating shaft 22, and the two ends of the limiting rods 73 are respectively connected to the two transverse plates 21, which can prevent the reciprocating seat 71 from rotating.

[0030] See also Figures 1 to 4Preferably, elastic pads are provided in the placement grooves. When the active seat 3 and the driven seat 4 clamp the test tube, the elastic pads are in a compressed and deformed state. The surfaces of the elastic pads are provided with rough surfaces, which can achieve clamping and driving effects.

[0031] See also Figures 1 to 4 Preferably, a plurality of connecting blocks are provided on the side wall of the placement seat 2 close to the base 1, and a plurality of arc grooves 13 are provided on the side wall of the base 1. The connecting blocks and the arc grooves 13 are slidably connected one by one, which can improve the stability of the placement seat 2.

[0032] See also Figures 1 to 4 Preferably, a plurality of telescopic shafts 44 are provided between the turntable 41 and the horizontal plate 21 located at the top of the placement seat 2 to prevent the turntable 41 from rotating.

[0033] See also Figures 1 to 4 Preferably, the driving member 23 is a rotating motor that can provide sufficient power.

[0034] During the implementation of the present invention, the user first places the test tube containing fat tissue on the active seat 3, and then starts the driving member 23. The driving member 23 rotates forward. At this time, the first ratchet cooperates with the first pawl, the second ratchet does not cooperate with the second pawl, and the third ratchet does not cooperate with the third pawl. The first shaft sleeve 5 rotates, and the second shaft sleeve 6 and the third shaft sleeve 7 do not rotate. The first shaft sleeve 5 drives the driven shaft 43 to rotate, so that the sleeve 42 drives the turntable 41 and the driven seat 4 to descend, thereby achieving stable clamping of the test tube. Then the drive is driven. The movable member 23 reverses, at which time the first ratchet does not cooperate with the first pawl, the second ratchet cooperates with the second pawl, and the third ratchet cooperates with the third pawl. The first shaft sleeve 5 does not rotate, and the second shaft sleeve 6 and the third shaft sleeve 7 rotate. During the rotation of the second shaft sleeve 6, the reciprocating seat 71 reciprocates along the second shaft sleeve 6. Under the action of the fixed gear 12 and the rack 72, the placement seat 2 as a whole swings back and forth within a certain angle range. During the rotation of the third shaft sleeve 7, the active seat 3 drives the test tube to rotate to complete the centrifugation of the fat tissue.

[0035] The utility model provides a fat tissue extraction device, which has the following beneficial effects:

[0036] 1. By setting the placement seat, active seat and driven seat, it can not only realize the automatic clamping of the test tube, but also drive the test tube to rotate to complete centrifugation, and also make the test tube swing within a certain angle range, thereby improving the centrifugal efficiency and ensuring a good centrifugal effect.

[0037] 2. This device only needs one driving part to operate, which reduces the weight of the device and the cost of use.

[0038] In summary, the beneficial effects of the present invention are as follows: it can not only realize automatic clamping of the test tube, but also drive the test tube to rotate, and also make the test tube swing within a certain angle range, thereby ensuring good centrifugal efficiency and centrifugal effect.

[0039] Of course, the present invention may have a variety of embodiments.
