Description

Technical Field

[0001] The utility model relates to the technical field of fat needles, in particular to a liposuction needle with a cutting function. Background Art

[0002] Liposuction, also known as fat aspiration, is a procedure that involves inserting an instrument through a small incision in the skin into the subcutaneous fat layer to remove fat fragments and absorb fat. It is suitable for body shaping. Liposuction can not only quickly achieve the goal of weight loss, but also use the absorbed fat cells for filling the face and chest. During liposuction, a liposuction needle is an essential surgical instrument. The existing liposuction needle is a tubular structure with a liposuction hole. During liposuction, the needle is moved left and right along the axis of the needle. The liposuction hole acts as a cutting tool to a certain extent, removing fat particles and fat fibers from the human body and drawing them out of the body through the needle tube through negative pressure.

[0003] Since the wall height of the liposuction hole of the existing liposuction needle is usually the thickness of the needle body of the liposuction needle, the fat cutting effect is not obvious during use, the liposuction rate is slow, and the liposuction efficiency is low; for areas with tight tissue, the skin tissue is tightly connected, and the liposuction needle encounters large resistance during the pulling process, resulting in poor liposuction effect. Utility Model Content

[0004] The purpose of the utility model is to overcome the problems of poor fat fiber cutting and large resistance in the pulling process of the existing liposuction needle, and to provide a liposuction needle with a cutting function.

[0005] A liposuction needle with a cutting function comprises a needle seat and a hollow needle tube, wherein a liposuction hole is provided on the front end of the needle tube; a blade portion is provided on the side wall of one end of the liposuction hole, and a pressing portion is provided on the side wall of the liposuction hole opposite to the blade portion, wherein the blade portion and the pressing portion are parallel to the radial line of the needle tube.

[0006] Furthermore, the blade portion and the pressing portion of the two adjacent liposuction holes are arranged in opposite directions.

[0007] Furthermore, the blade portion is arranged on any one side of the upper side, the middle side or the lower side of the wall of the liposuction hole.

[0008] Furthermore, the liposuction hole is configured to be in a water drop shape.

[0009] Furthermore, the blade portion is located at the wide side of the water drop hole, and the pressing portion is located at the narrow side of the water drop hole.

[0010] Furthermore, the liposuction hole is arranged in a spiral shape.

[0011] Furthermore, the blade portion and the pressing portion are respectively located at the long sides of the spiral.

[0012] The beneficial effects of the present invention are as follows: the present invention is capable of cutting off fat fibers and particles by integrally extending a blade portion at the wall of the liposuction hole, thereby facilitating the suction of fat; and at the same time, combined with the integrally formed downward pressing portion on the opposite side, it is capable of effectively reducing the contact resistance between the fat tissue and the wall of the liposuction hole, thereby reducing the difficulty of liposuction and improving the efficiency of liposuction.

[0021] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0022] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0023] Example 1

[0024] like Figures 1-2 As shown, a liposuction needle with a cutting function includes a needle seat 2 and a hollow needle tube 1. The end of the needle tube 2 forms an acute angle, and the end face of the needle tube 2 is an arc surface, which reduces the insertion resistance and allows the liposuction needle to be smoothly inserted into the skin while reducing damage to the skin, muscles, etc.

[0025] A liposuction hole 3 is provided on the front end of the needle tube 1; in the present embodiment, the liposuction hole 3 is set in a water drop shape, specifically, the liposuction holes 3 are set in at least two groups, preferably three groups or four groups, namely a first hole group 100 and a second hole group 200, wherein the first hole group 100 and the second hole group 200 are composed of a plurality of liposuction hole arrays, and two adjacent liposuction holes are staggered.

[0026] A blade portion 31 is provided on one sidewall of the liposuction hole 3, and a pressing portion 32 is provided on the sidewall opposite the blade portion 31. The blade portion 31 and the pressing portion 32 are parallel to the radial line of the needle tube 1. Specifically, the blade portion 31 is located at the wide side of the water drop hole, and the pressing portion 32 is located at the narrow side of the water drop hole. During use, the blade portion 31 is used to cut fat, while the pressing portion 32 creates an inclined shape when the wall of the liposuction hole 3 contacts the fat, thereby reducing pull resistance.

[0027] The blades 31 and the pressing portions 32 of the two adjacent liposuction holes 3 are arranged in opposite directions. Specifically, by adopting the adjacent and opposite arrangements, the liposuction needle can cut the fibers during the pulling process.

[0028] On the other hand, in order to achieve that the blade portion 31 can completely remove the fat fibers, such as Figures 5-7 As shown, the blade portion 31 is provided on any one of the upper side, middle side, or lower side of the wall of the liposuction hole 3. In this embodiment, the blade portion 31 is provided integrally with the needle tube 1, and one side of the wall of the liposuction hole 3 is ground into a blade. Preferably, from the perspective of process processing, the blade portion 31 is ground and provided on the upper side of the wall of the liposuction hole 3.

[0029] Example 2

[0030] like Figures 3-4As shown, this embodiment 2 is the same as embodiment 1, except that the liposuction hole 3 is configured in a spiral shape. Specifically, two spiral liposuction holes are provided, namely a first threaded hole 300 and a second threaded hole 400, which are arranged in a vertically circumferential manner on the wall of the needle tube 1. The blade portion 31 of the first threaded hole 300 is located near the needle head; the blade portion 31 of the second threaded hole 400 is located near the needle seat 2. The blade portions 31 of the two adjacent spiral holes are offset in opposite directions, enabling the liposuction needle to cut the fiber during the withdrawal process.

[0031] In order to achieve the cutting effect of the spiral hole, the blade portion 31 and the pressing portion 32 are arranged along the pulling direction of the liposuction needle. Specifically, the blade portion 31 and the pressing portion 32 are respectively located at the long sides of the spiral.

[0032] The utility model is provided with a blade portion integrally extending from the hole wall of the liposuction hole, which can cut off fat fibers and particles, making it easier to suck fat. At the same time, combined with the downward pressure portion integrally formed on the opposite side, it can effectively reduce the contact resistance between the fat tissue and the hole wall of the liposuction hole, reduce the difficulty of liposuction, and improve the efficiency of liposuction.

[0033] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
