Background

In the existing weight-losing industry, liposuction surgery is a common medical measure. The liposuction operation is to use the principle of negative pressure suction to draw out fat through a needle tube by attaching a liposuction needle to the lower part of the dermis with a liposuction part. The existing liposuction needle is a tubular structure provided with a liposuction hole, the needle tube moves left and right along the axis direction of the needle tube in the liposuction process, the liposuction hole plays a role in cutting to a certain extent, fat particles are cut off from a human body and are pumped out along the needle tube through negative pressure, and the existing liposuction needle has the following defects: the fat cutting effect of the fat suction hole of the fat suction needle is not obvious, the fat suction speed is slow, and the fat suction efficiency is low; the liposuction needle is easy to deform when being used for a long time, is inconvenient for sucking fat, influences the liposuction effect and causes uneven fat suction; for the position with compact tissue, the skin tissue is tightly connected, the fat absorption resistance is large, and the fat absorption effect is not good. Therefore, the existing liposuction needle has the problems of low liposuction efficiency, easy deformation and poor liposuction effect on the part with compact tissue.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a bellied liposuction needle of opening. The utility model has the characteristics of liposuction is efficient, non-deformable, the position liposuction effect that compacts to the tissue is better.

The technical scheme of the utility model: a liposuction needle with a convex opening comprises a needle seat and a hollow needle tube, wherein a plurality of liposuction holes are formed in the surface of the head of the needle tube along the length direction of the needle tube, and a convex part higher than the outer surface of the needle tube is formed at the joint of the opening of each liposuction hole and the outer surface of the needle tube.

In the aforementioned liposuction needle with a raised opening, the top of the raised portion is in a sharp angle shape.

In the above-mentioned liposuction needle with a convex opening, a convex portion is formed between one side of the liposuction hole close to the opening of the head of the needle tube and the outer surface of the needle tube, and an obtuse angle is formed between one side of the liposuction hole close to the opening of the tail of the needle tube and the outer surface of the needle tube.

In the fat absorption needle with the convex opening, the opening of the fat absorption hole is in a waist hole shape, and the connecting surface of the opening of the fat absorption hole and the needle tube is an arc surface.

In the above-mentioned liposuction needle with a convex opening, an acute angle is formed at the end of the needle tube, and the end surface of the needle tube is a cambered surface.

In the bellied liposuction needle of opening, the afterbody movable sleeve of needle tubing is equipped with spacing head, and threaded connection has the parcel at the outside sleeve of needle tubing on spacing, and the sleeve is close to the one end of head and is equipped with the guard ring, is equipped with flexible pad on the guard ring.

Compared with the prior art, the utility model is provided with the convex part at the joint of the fat suction hole and the outer surface of the needle tube, which is mainly used for the patients with severe obesity or the parts with thicker fat layer, the convex part reduces the fat suction resistance when the fat layer is inserted and extracted, the fat suction smoothness is high, the fat scraping and sucking function can be realized under the condition of very small negative pressure, and the operation efficiency of doctors can be greatly improved; the bulge part also strengthens the strength of the needle tube, so that the needle tube is not easy to deform and the grease pumping uniformity is improved; in addition, for the position that the tissue is tight, use the liposuction needle that has the bellying and can effectively cut off the tissue and aspirate, reduce the liposuction degree of difficulty, the liposuction effect is better.

Therefore, the utility model has the characteristics of liposuction is efficient, non-deformable, the position liposuction effect that compacts to the tissue is better.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

The labels in the figures are: 1. a needle seat; 2. a needle tube; 3. a liposuction hole; 4. a boss portion; 5. a limiting head; 6. a sleeve; 7. a guard ring; 8. a flexible mat.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given.

As shown in figure 1, the liposuction needle with the convex opening comprises a needle seat 1 and a hollow needle tube 2, wherein a plurality of liposuction holes 3 are formed in the head surface of the needle tube 2 along the length direction of the needle tube 2, and a convex part 4 higher than the outer surface of the needle tube 2 is formed at the joint of the opening of the liposuction hole 3 and the outer surface of the needle tube 2. The liposuction needle is mainly used for severely obese patients or parts with thicker fat layers, the convex part 4 can play a role of scraping and sucking fat under the condition of very small negative pressure when the fat layers are inserted and drawn, the liposuction resistance is reduced, the liposuction smoothness is high, and the operation efficiency of doctors can be greatly improved; the bulge 4 also strengthens the strength of the needle tube 2, so that the needle tube is not easy to deform and the grease pumping uniformity is improved.

The top of the boss 4 is pointed. For the parts with compact tissues, such as the precious bags, the accessory breasts and the like, the pointed convex parts 4 can cut off the tissues and suck out the tissues more effectively, and the effect is better. The protruding size of the boss 4 varies according to the fat degree of the fat absorption part and the patient, and the fat absorption efficiency of the fat absorption needle with large protruding size can be improved by the fat absorption needle with heavy fat and a thicker fat layer.

A bulge part 4 is formed between one side of the opening of the grease suction hole 3 close to the head part of the needle tube 2 and the outer surface of the needle tube 2, and an obtuse angle is formed between one side of the opening of the grease suction hole 3 close to the tail part of the needle tube 2 and the outer surface of the needle tube 2. The opening of the liposuction hole 3 is in a waist hole shape, and the connecting surface of the opening of the liposuction hole 3 and the needle tube 2 is an arc-shaped surface. The design is convenient for the cut tissue, especially some large fat particles and the like fall into the liposuction hole 3 along with the arc-shaped surface to be sucked out, and the blocking and the falling condition outside the needle tube 2 are reduced.

The end part of the needle tube 2 forms an acute angle, and the end surface of the needle tube 2 is a cambered surface. The insertion resistance is reduced, so that the fat suction needle is smoothly inserted into the skin, and the damage to skin muscles and the like is reduced.

The tail of the needle tube 2 is movably sleeved with a limiting head 5, the limiting head 5 is connected with a sleeve 6 wrapped outside the needle tube 2 in a threaded mode, one end, close to the head, of the sleeve 6 is provided with a protective ring 7, and a flexible pad 8 is arranged on the protective ring 7. The sleeve 6 can move back and forth along the needle tube 2 under the action of the limiting head 5, so that the strength of the needle tube 2 is increased, the sleeve 6 is moved to a skin wound when the medical needle is used, the wound is effectively sealed and protected by the protective ring 7, the space contacting with the outside is reduced, and the bacterial infection rate is reduced; the provision of a flexible pad 8 improves comfort.

The part of the utility model not detailed is prior art.
