Description

Technical Field

[0001] The utility model relates to the technical field of medical needle tubes, in particular to a fat tissue aspiration tube. Background Art

[0002] Stem cells are the most primitive cells in the human body and have a strong ability to differentiate and regenerate. They have been listed as one of the hot spots of scientific and technological development since the 21st century.

[0003] ADSCs (adipose-derived stem cells) are mesenchymal stem cells derived from adipose tissue. They are widely available and easy to obtain. They can be extracted from adipose tissue obtained through liposuction. Their extraction efficiency is 40 times higher than that of bone marrow mesenchymal stem cells (BMSCs), and their proliferation rate is faster under in vitro culture conditions. They have multidirectional differentiation capabilities and can differentiate into adipocytes, osteoblasts, chondrocytes, cardiomyocytes, and even neurons under different induction schemes. They have low immunogenicity and do not cause host immune rejection. Therefore, ADSCs are one of the ideal sources of stem cells. Current clinical phase I and phase II trials have shown that the application of ADSCs in the repair of various organ injuries such as the heart, rectum, and breast is safe, effective, and feasible, and ADSCs have been shown to promote skin regeneration and repair.

[0004] The fat obtained by liposuction includes a superficial fat layer, a deep fat layer, a subcutaneous fixed fat layer and a small amount of superficial fascia layer; it is mostly semi-solid, and because it is mixed with substances such as fascia, the fat extracted by liposuction is clustered in multiple layers and is difficult to be evenly dispersed. Therefore, it is difficult to achieve transfer operation during fat processing; the existing pipette is designed to transfer liquid, and the pipette nozzle is designed to be a thinner tube diameter, mostly 1mm in diameter; this design is not suitable for heterogeneous semi-solid substances such as fat tissue, especially for fat tissue with a relatively large amount of fascia, and the purpose of aseptic transfer operation through the pipette cannot be achieved; the existing suction tube has a simple structure and the nozzle is still small, resulting in a slow fat absorption speed, thereby prolonging the operation time, and the suction tube is also prone to blockage of fat tissue; in addition, the nozzle of the suction tube cannot thoroughly suction the superficial, deep and subcutaneous fixed fat layers. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a fat tissue suction tube, which solves the problems of the existing suction tubes such as small orifice, slow fat suction speed and easy clogging.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

[0007] A fat tissue suction tube is provided, which includes a tube body, a suction reamer is provided at the front end of the tube body, a cutting edge is provided along the edge of the suction reamer, a rear end of the tube body is provided with an internal thread that cooperates with the thread of a negative pressure joint, the negative pressure joint is externally connected to a negative pressure suction device, and the inner wall of the tube body is provided with a plurality of blades for crushing fat.

[0008] Furthermore, the suction expansion hole is composed of a semicircular port, a radial semicircular incision and an axial straight line incision. The two ends of the semicircular port and the radial semicircular incision are connected by an axial straight line incision, and the axial projections of the semicircular port and the radial semicircular incision together constitute the axial projection of the tube body.

[0009] Furthermore, the extending direction of the cutting edge tips on the semicircular port and the radial semicircular cut is parallel to the extending direction of the tube body, and the extending direction of the cutting edge tips on the axial linear cut is parallel to the tangent direction of the axial linear cut.

[0010] Furthermore, a plurality of blades are evenly arranged in the axial and circumferential directions of the inner wall of the tube body, the blades are fin-shaped, and the tips of the blades are inclined toward the suction and expansion hole.

[0011] Furthermore, a cylindrical holding head is fixedly sleeved on the side wall of the tube body near the rear end thereof, and the peripheral wall surface of the holding head is a concave-convex surface.

[0012] Furthermore, a plurality of valves are evenly spaced apart in the extension direction of the interior of the tube body.

[0013] Furthermore, the tube body is a transparent tube made of transparent medical plastic.

[0014] Furthermore, scale lines are provided on the extension direction of the outer side wall of the tube body.

[0015] Furthermore, the radial dimension of the tube body is 0.5-1 cm.

[0016] The beneficial effects of the utility model are:

[0017] 1. This solution expands the size of the front port of the tube body by setting up a suction reaming hole, thereby improving the effect of fat suction and reducing the possibility of fat tissue blockage; at the same time, the suction reaming hole can cover a certain axial range, which is conducive to the suction reaming hole to thoroughly suction the superficial, deep and subcutaneous fixed fat layers; this solution also sets a number of blades on the inner wall of the tube body to cut and crush the fat tissue entering the tube body, further reducing the possibility of fat tissue blockage, improving liposuction efficiency, and reducing liposuction time during surgery, thereby reducing surgical risks.

[0018] 2. This solution uses cutting edges on the semicircular port and the radial semicircular incision to assist in cutting fat tissue when the tube is inserted. Uses cutting edges on the axial linear incision to assist in scraping away fat tissue around the tube when it is rotated, which is beneficial for thorough aspiration of fat tissue.

[0019] 3. This solution can separate the fat tissue located on the inner wall of the tube through several valves, effectively preventing the backflow of fat tissue and facilitating the suction of fat tissue. BRIEF DESCRIPTION OF THE DRAWINGS
