Description

Technical Field

[0001] The utility model relates to the technical field of liposuction needles for plastic surgery, and in particular to a needle head and a device for medical aesthetic plastic surgery. Background Art

[0002] Fat suction in medical cosmetic surgery is a cosmetic surgery method that uses a negative pressure vacuum aspirator and a metal tubular liposuction needle with a fine hole at the end to enter the subcutaneous tissue through a small incision in the skin to suck out locally accumulated adipose tissue in order to improve obese body shape.

[0003] For example, a liposuction needle is disclosed in the patent authorization announcement number CN 217091569 U. Figure 1 shown.

[0004] The front end structure of the liposuction needle has two structures: a pointed needle and a blunt needle. The side wall of the front end of the blunt needle is provided with a suction hole. The liposuction needle may sometimes be blocked during use, requiring the operator to remove the liposuction needle, clean it, and then reinsert it into the part of the human body where liposuction is required. This will cause pain to the patient, and repeated removal and insertion may easily lead to bacterial contamination and infection if the operation is not done properly. Utility Model Content

[0005] In view of the problems pointed out in the background technology, the utility model proposes a needle and a device for medical aesthetics and plastic surgery to solve the above technical problems.

[0006] The technical solution of the utility model is achieved in this way:

[0007] A needle for medical cosmetic surgery comprises a needle tube. A suction hole is arranged on the side wall of the front end of the needle tube. A slit corresponding to the suction hole is arranged on the side wall of the needle tube. The slit runs through both sides of the needle tube. The slit is connected to the suction hole.

[0008] The utility model is further configured that the slit is arranged along the front-to-back direction, and the front end of the slit is connected to the suction hole.

[0009] The utility model is further configured that two cutting slits are provided, and the two cutting slits are parallel and spaced apart.

[0010] The utility model is further configured that two suction holes are provided, and the two suction holes are respectively arranged on two opposite side walls of the needle tube, and two slits communicating with the corresponding suction holes are respectively provided on the two opposite side walls of the needle tube.

[0011] The utility model is further configured such that the side wall of the needle tube between the two slits on the same side is a deformable deformable portion, and further comprises a breaking strip, the two ends of the breaking strip are respectively fixedly connected to the front ends of the two deformable portions.

[0012] The utility model is further configured that the breaking strip is in the shape of a long strip, the cross section of the breaking strip is in the shape of a diamond, and the front and rear sides of the breaking strip form a cutting edge.

[0013] The utility model is further configured such that the front end of the needle tube is closed.

[0014] The utility model is further configured that the rear end of the needle tube is connected to a gripping portion, the front end of the gripping portion is connected to the needle tube, and the rear end of the gripping portion is connected to a joint.

[0015] The utility model is further configured that the suction hole is an elliptical structure.

[0016] A device for medical cosmetic surgery comprises the above-mentioned needle, wherein the needle tube is connected to a vacuum negative pressure aspirator.

[0017] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0018] (1) A slit connected to the suction hole is provided on the side wall of the needle tube near the suction hole. In this way, if the suction hole is blocked, the side wall of the needle tube can be deformed at the slit position to loosen the blockage and clear the blockage.

[0019] (2) Relative deformation parts are formed on the two side walls of the needle tube, and the two deformation parts are connected by a dividing strip. When in use, the needle tube moves back and forth, and the dividing strip can form a cutting state, thereby cutting off and clearing the blockage. Moreover, the provision of two deformation parts helps the two deformation parts to undergo unbalanced deformation (for example, if one side of one deformation part is more severely blocked and the other deformation part is less blocked, deformation will occur toward the side where the other deformation part is located).

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] For reference Figure 1-5 The utility model is described as follows:

[0029] Embodiment 1: A needle for medical cosmetic surgery comprises an elongated needle tube 1. The front end of the needle tube 1 is closed and has a blunt needle structure. The rear end of the needle tube 1 is connected to a gripping portion 7. The front end of the gripping portion 7 is connected to the needle tube 1. The rear end of the gripping portion 7 is connected to a connector 8. When in use, fat enters the needle tube 1, passes through the gripping portion 7, and then enters the connector 8. The connector 8 is connected to a vacuum negative pressure suction device 9.

[0030] A suction hole 2 is provided on the side wall of the front end of the needle tube 1. There are two suction holes 2, which are respectively arranged on two opposite side walls of the needle tube 1. The suction holes 2 are elliptical structures.

[0031] The opposite side walls of the needle tube 1 are respectively provided with slits 3 corresponding to the two suction holes 2. The slits 3 are arranged through the inner and outer sides of the needle tube 1, and are arranged along the front-to-back direction. The slits 3 are located at the rear side of the suction hole 2, and the front end of the slits 3 is connected to the suction hole 2. Each suction hole 2 corresponds to two slits 3, and the two slits 3 on the same side are parallel and spaced apart. The side wall of the needle tube 1 between the two slits 3 on the same side is a deformable portion 4 that can be deformed. By adopting the above technical solution, when the suction hole 2 is blocked, the deformable portion 4 can be deformed to loosen the blockage, and the loosening forms a channel for the blockage.

[0032] The needle tube 1 further comprises a separating strip 5, which is in the shape of a long strip, and the two ends of the separating strip 5 are respectively fixedly connected (welded) to the front ends of the two deformed parts 4. The separating strip 5 is in the shape of a long strip, and the cross section of the separating strip 5 is a diamond shape, and a cutting edge 6 is formed on the front and rear sides of the separating strip 5. By adopting the above technical solution, when the needle tube 1 is moved back and forth for use, the separating strip 5 can play the role of cutting and separating the fat entering the suction hole 2, which can avoid blockage and can also play the role of clearing the blockage.

[0033] A device for medical cosmetic surgery includes the above-mentioned needle. The needle tube 1 is connected to a vacuum negative pressure aspirator 9 through a joint 8. The vacuum negative pressure aspirator 9 can be a manual syringe or an electric vacuum pump structure.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
