[0002] At present, the devices for clinically extracting stem cells have limitations such as complex structure, heavy weight, large volume, and high price, and are currently only applied to a small extent in clinical practice. At the same time, the shearing process of adipocytes is carried out manually, which will cause damage to a large number of cells, reduce the survival rate of stem cells, and result in waste of blood; the operation steps are cumbersome, the manual operation has a large randomness and inaccurate control, which is not conducive to popularization and application.

[0003] To solve the above problems, the Chinese utility model patent (Publication No.: CN207016762U) discloses a "cell experiment extraction device", which drives a separation shaft and a separation head to rotate through a micro motor to disperse adipose tissue and then extract it. However, the position of the separation head is fixedly set and the separation head is located inside the liposuction tube, which limits its flexible application during use; therefore, we make improvements on this and propose an extraction device for in vivo adipocytes.

In this application, through the arranged electric telescopic rod 401, the electric telescopic rod 401 can drive the micro drive motor 3 to move, so that the position of the main body of the separation head 406 can be adjusted, improving the operation flexibility and precision. When necessary, the main body of the separation head 406 can also extend outside the main body of the liposuction tube 2, enabling it to directly act on the target fat tissue without inserting the entire main body of the liposuction tube 2 into the target fat tissue, reducing trauma and the discomfort of the patient. Moreover, after the main body of the separation head 406 extends, the obstruction of the main body of the liposuction tube 2 is reduced, allowing the operation process of the main body of the separation head 406 to be directly seen.

[0030] Further, as Figure 2 shown, a first piston 405 is slidably connected inside the protective shell 1. A sealing bearing is arranged between the outer surface of the first piston 405 and the transmission shaft 404. The first piston 405 can support the transmission shaft 404.

[0031] Further, as Figure 2 shown, a slide rail 403 is installed inside the protective shell 1. A slide seat 402 is slidably connected to the outer surface of the slide rail 403. The slide seat 402 is connected to the micro drive motor 3. By the mutual cooperation of the slide seat 402 and the slide rail 403, the micro drive motor 3 can be supported and limited, thereby improving the stability of the micro drive motor 3 during the moving process.

[0032] Further, as Figure 2 shown, a support plate 4 is fixedly installed inside the protective shell 1. The support plate 4 is fixedly connected to the electric telescopic rod 401. The support plate 4 can support the electric telescopic rod 401.

[0033] Embodiment 2 further optimizes the extraction device for in vivo fat cells provided in Embodiment 1. Specifically, as Figure 2 shown, the bottom of the protective shell 1 is fixedly communicated with a first connecting pipe 101. The outer surface of the first connecting pipe 101 is threadedly connected to a second connecting pipe 5. One end of the second connecting pipe 5 is fixedly connected to a storage cylinder body 501. A second piston 502 is slidably connected inside the storage cylinder body 501.

The moving trajectory of the first piston 405 does not pass through the first connecting pipe 101. An air hole located on the right side of the moving trajectory of the first piston 405 is opened on the protective shell 1.

[0034] Further, as Figure 2As shown, one end of the storage cylinder 501 away from the main body 2 of the liposuction tube is fixedly connected with a wing plate 504. The wing plate 504 is provided to facilitate the operation of the piston rod 503 by medical staff.

[0035] Embodiment 3 further optimizes the extraction device for in-vivo fat cells provided in Embodiment 1 or 2. Specifically, as Figure 1 - Figure 3 shown, a second fixed seat 802 and a third fixed seat 804 are fixedly installed on the protective shell 1. A grip 8 is arranged between the second fixed seat 802 and the third fixed seat 804. An accommodation groove 806 adapted to the main body 2 of the liposuction tube is formed on the grip 8. The grip 8 is for the hand of medical staff during use. Before use, the main body 2 of the liposuction tube can be protected through the mutual cooperation of the accommodation groove 806 and the grip 8, reducing the damage of the main body 2 of the liposuction tube.

[0036] Furthermore, as Figure 1 - Figure 3 shown, a socket 801 is formed on the grip 8. An insertion plate 803 is inserted through the inner wall of the socket 801. One end of the insertion plate 803 is fixedly connected with the second fixed seat 802. The cooperation of the insertion plate 803, the second fixed seat 802 and the socket 801 can limit the position of the grip 8.

[0037] Furthermore, as Figure 1 - Figure 3 shown, a hand-tightening bolt 805 is threadedly connected to the grip 8. One end of the hand-tightening bolt 805 is connected with the third fixed seat 804. The cooperation of the hand-tightening bolt 805 and the third fixed seat 804 can further limit the position of the grip 8.

[0038] Furthermore, as Figure 1 and Figure 2 shown, a first fixed seat 7 is also fixedly installed on the protective shell 1. Through holes for the hand-tightening bolt 805 to pass through are formed on both the first fixed seat 7 and the third fixed seat 804. When the main body 2 of the liposuction tube is inserted into the accommodation groove 806, the position of the grip 8 can be limited through the cooperation of the hand-tightening bolt 805 and the first fixed seat 7.
