Description

Technical Field

[0001] The utility model relates to the technical field of fat extraction, in particular to an extraction device for fat surgery. Background Art

[0002] Adipose tissue is composed of a large number of clustered fat cells, which are separated into lobules by a thin layer of loose connective tissue. The reticular fibers in adipose tissue are well developed. Adipose tissue has very little intercellular matrix. The fat in the joints of adipose tissue has the function of buffering muscle movement, and the fat in the arms and soles of the feet has a cushioning effect. Since adipose tissue does not cause a strong rejection reaction when transplanted, and adipose tissue is widely distributed, it has a wide range of applications, so it is necessary to extract adipose tissue.

[0003] Existing fat extraction generally uses a filter to filter the fat alone. Although adipose tissue can be obtained, the product is usually mixed with plasma and oil, resulting in a general purity of the extracted adipose tissue. Based on this, we propose an improved extraction device for fat surgery. Utility Model Content

[0004] The main purpose of the utility model is to provide a fat extraction device for surgery, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a fat extraction device for surgery includes a centrifugal barrel 1, a filter cartridge 6 and a sleeve 8. A driving shaft 2 is rotatably sleeved on the bottom plate of the centrifugal barrel 1, a driving disk 3 is fixedly sleeved on the outer wall of the driving shaft 2, a mounting seat 4 is fixedly connected to the lower end of the filter cartridge 6, the mounting seat 4 is threadedly sleeved on the outer wall of the driving disk 3, a mounting cover 7 is threadedly sleeved on the upper end of the filter cartridge 6, the sleeve 8 is slidably sleeved on the outer wall of the filter cartridge 6, an end cover 11 is threadedly sleeved on the upper end of the centrifugal barrel 1, a feed pipe 12 is fixedly sleeved on the middle part of the end cover 11, and the lower end of the feed pipe 12 is connected to the inside of the filter cartridge 6.

[0024] In this embodiment, the lower end of the mounting seat 4 is made of a conical structure for easy material discharge. The upper end of the drive shaft 2 is connected to the interior of the filter cartridge 6. A drain pipe 14 is rotatably sleeved inside the drive shaft 2 near the lower end. A discharge pipe 13 is fixedly sleeved on one side of the centrifugal barrel 1 near the bottom plate. Valves are rotatably provided on the feed pipe 12, the discharge pipe 13 and the drain pipe 14 to control the opening and closing of the valves.

[0025] In this embodiment, a motor 15 is fixedly connected to one side of the lower end surface of the centrifugal bucket 1, and a bevel gear 17 is fixedly sleeved on the output end of the motor 15. The lower end of the drive shaft 2 passes through the bottom plate of the centrifugal bucket 1 and is fixedly sleeved with a bevel gear 18. The bevel gear 17 is meshed with the bevel gear 18. The motor 15 drives the bevel gear 17 to rotate, thereby driving the bevel gear 18 to rotate, and then driving the drive shaft 2 to rotate. A fixed plate 16 is fixedly sleeved on the outer wall of the discharge pipe 14, and the other end of the fixed plate 16 is fixedly installed on the lower end surface of the motor 15. The fixed plate 16 is used to prevent the discharge pipe 14 from rotating with the drive shaft 2.

[0026] In this embodiment, a sealing magnetic strip 1 5 is fixedly connected to the upper end of the mounting seat 4, and a sealing magnetic strip 2 9 is fixedly connected to the lower end of the sleeve 8. The sealing magnetic strip 1 5 and the sealing magnetic strip 2 9 are symmetrically arranged. By adsorbing the sealing magnetic strip 2 9 by the sealing magnetic strip 1 5, the sleeve 8 can seal the filter cartridge 6, thereby preventing excessive saline from flowing out during the rotation of the filter cartridge 6, resulting in unclear stratification of fat tissue.

[0027] In this embodiment, the mounting cover 7 and the sleeve 8 are both slidably sleeved on the outer wall of the feed pipe 12, and the feed pipe 12 can be used to directly feed the filter cartridge 6. The mounting seat 4 is slidably sleeved on the outer wall of the drive shaft 2. When the mounting seat 4 is disassembled, it can be directly removed from the drive shaft 2.

[0028] In this embodiment, a lifting handle 10 is rotatably connected to the upper end of the sleeve 8, which facilitates lifting the sleeve 8 by means of the lifting handle 10. The direction of rotation of the drive shaft 2 is the same as the direction of the threaded screwing of the drive disk 3, which prevents the mounting seat 4 from being screwed out of the drive disk 3 during the rotation of the mounting seat 4 driven by the drive disk 3. One end of the sleeve 8 is slidably sleeved on the inner wall of the end cover 11, and a gap is provided between the sleeve 8 and the inner wall of the end cover 11 to reduce the contact friction of the end cover 11 when the sleeve 8 rotates.

[0029] The direction of rotation of the drive shaft 2 and the direction of threading of the drive disc 3 are the same.

[0030] It should be noted that the utility model is a fat extraction device for surgery. When in use, adipose tissue and saline are added into the feed tube 12 through a syringe. After the addition is completed, the valve on the feed tube 12 is closed, and the motor 15 is started. By utilizing the meshing relationship between the bevel gear 17 and the bevel gear 2 18, the motor 15 will be able to indirectly drive the drive shaft 2 to rotate, and then drive the drive disk 3 to rotate, and then drive the mounting seat 4 to rotate, and then drive the filter cartridge 6 to rotate, and the adipose tissue is layered by centrifugation. After the centrifugation is completed, the valve on the discharge pipe 14 is opened, and the plasma and oil in the lower layer of the saline are discharged through the hollow cavity of the drive shaft 2, and then the valve is closed. After unscrewing the end cover 11, the sleeve 8 is removed from the filter cartridge 6 by pulling the handle 10. As the mesh of the filter cartridge 6 is exposed, the saline is discharged from the filter cartridge 6 through the mesh. The valve on the discharge pipe 13 is opened to discharge the saline, and then the filter cartridge 6 is rotated to remove the mounting seat 4 from the drive disk 3, and then the filter cartridge 6 is taken out of the centrifuge barrel 1, and then the installation cover 7 is unscrewed to take out the adipose tissue, which is convenient and trouble-free.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
