Description

Technical Field

[0001] This utility model relates to an apparatus for preparing adipose tissue, belonging to the field of adipose tissue preparation technology. Background Technology

[0002] Vascular matrix components (SVF) are effective components extracted from adipose tissue taken from the patient's own body. They contain a variety of cells with repair functions, such as hematopoietic stem cells, endothelial progenitor cells, vascular precursor stem cells, pericytes, anti-inflammatory cells, lymphocytes, and macrophages, as well as more than 100 cytokines and exosomes and other important functional elements. They have wide application value in clinical fields such as tissue repair and fat transplantation.

[0003] In existing technologies, the preparation of adipose tissue for transplantation typically requires processing the aspirated fat to remove impurities and reduce fat particle size. However, existing preparation methods have several drawbacks: some methods use chemical reagents, posing a risk of chemical damage that may affect the bioactivity of the adipose tissue and the safety of transplantation; other methods rely on vigorous manual shaking of the container to break up the adipose tissue, which is not only inefficient and time-consuming but also results in inconsistent breaking up, making it difficult to ensure the uniformity of fat particle size and affecting the transplantation outcome. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an adipose tissue preparation device that can stably prepare adipose tissue for transplantation without chemical reagent treatment, and can do so by manual mechanical force alone, thereby improving the efficiency of adipose tissue preparation and ensuring the uniformity of adipose particle size.

[0005] The adipose tissue preparation device of this utility model includes an outer cylinder, an upper end cap sealed to the upper end of the outer cylinder, and a lower end cap sealed to the lower end of the outer cylinder. The upper end cap, the lower end cap, and the outer cylinder together form a cavity. A central shaft assembly is disposed through the center of the outer cylinder and can move up and down along the outer cylinder. A turbine blade is rotatably disposed on the central shaft assembly and is located in the cavity. The central shaft assembly can drive the turbine blade to move in the cavity. The upper end cap has an inlet and the lower end cap has an outlet.

[0006] Preferably, the central shaft assembly includes an upper push rod, a connecting rod, and a lower push rod, which are sequentially and fixedly connected.

[0007] Preferably, both the upper and lower end covers are equipped with sealing rings. The upper end cover is slidably and sealingly connected to the upper push rod through the sealing ring, and the lower end cover is slidably and sealingly connected to the lower push rod through the sealing ring.

[0008] Furthermore, the turbine blades are sleeved on the connecting rod and axially limited by the upper push rod.

[0009] Preferably, filter membranes are installed at the inlet and outlet to filter large fat particles and impurities.

[0010] The advantages of this utility model compared with the prior art are:

[0011] 1. This utility model does not use any chemical reagents throughout the entire process, but only mechanically shears the adipose tissue, thus avoiding the damage of chemical substances to the biological activity of the adipose tissue and ensuring the biosafety of the transplanted tissue.

[0012] 2. This utility model relies on a manually pushed and pulled central shaft assembly to drive the turbine blades to rotate under the resistance of the components inside the cavity. It does not require electricity or other power sources, has a simple structure, is small in size, and is easy to carry and operate.

[0013] 3. The shearing force generated by the rotation of the turbine blades is uniform and controllable, which can stably and quickly break down adipose tissue with high breaking efficiency and good particle size uniformity, meeting the requirements of clinical transplantation injection.

[0017] The present invention will be further described below with reference to specific embodiments.

[0018] like Figure 1-2 As shown, this embodiment is achieved through the following technical solution: it includes an outer cylinder 1, with an upper end cap 3 sealed to the upper end of the outer cylinder 1 and a lower end cap 4 sealed to the lower end of the outer cylinder 1. The upper end cap 3, the lower end cap 4, and the outer cylinder 1 together form a cavity 11. A central shaft assembly 2 is disposed through the center of the outer cylinder 1, and the central shaft assembly 2 can move up and down along the outer cylinder 1. A turbine blade 5 is rotatably disposed on the central shaft assembly 2, and the turbine blade 5 is located in the cavity 11. The central shaft assembly 2 can drive the turbine blade 5 to move in the cavity 11. The upper end cap 3 is provided with an inlet 31, and the lower end cap 4 is provided with an outlet 41.

[0019] In this embodiment, the central shaft assembly 2 includes an upper push rod 21, a connecting rod 22, and a lower push rod 23, which are sequentially and fixedly connected. Sealing rings are installed on both the upper end cover 3 and the lower end cover 4. The upper end cover 3 is slidably and sealingly connected to the upper push rod 21 via the sealing ring, and the lower end cover 4 is slidably and sealingly connected to the lower push rod 23 via the sealing ring. The turbine blades 5 are sleeved on the connecting rod 22 and axially limited by the upper push rod 21. Filter membranes are installed at the inlet 31 and outlet 41 to filter large fat particles and impurities.

[0020] The working process of this utility model is as follows:

[0021] 1. Install a T-connector at the inlet 31 to facilitate fat injection. Inject physiological saline into the cavity 11 through the inlet 31 to completely fill the cavity 11 and remove air.

[0022] 2. The extracted fat is injected into the cavity 11 through the inlet 31;

[0023] 3. Push and pull the upper push rod 21 and the lower push rod 23 back and forth axially. During the pushing process, the turbine blades 5 rotate under the action of resistance, generating shear force to break the fat into micro-fragments of 1-2mm.

[0024] 4. The broken adipose tissue is extracted from outlet 41 for clinical injection, and the filter membrane can further improve the purity of the adipose tissue.
