Background

Fat transplantation is increasingly applied in the fields of plastic reconstruction surgery for repairing tissue defects and cosmetic surgery for tissue expansion because of rich fat sources, no foreign body or foreign body rejection reaction from the body, simple operation and small wound. The current liposuction technology is limited by the structure of the liposuction needle, only a small area of fat can be extracted after the liposuction needle enters a fat layer, and when the fat extraction area is larger, the operation time and difficulty are increased because the liposuction needle can only puncture again.

The utility model discloses a 19 days of 9 months in 2017, chinese utility model patent that application number is 201621206348.7 discloses a curved liposuction needle, and this utility model adopts syllogic needle body structure, and each section needle body all has certain length and curvature radius, and the three-section needle body connects gradually and smooth transition, but this utility model has certain potential safety hazard because the unstable needle body landing of needle body connection easily in operation process.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a can increase the sleeve type liposuction needle of extraction area.

The utility model adopts the technical scheme as follows:

a sleeve-type liposuction needle comprises a liposuction needle head, a liposuction hole, a sleeve, a guide needle seat, a guide needle head and a drainage tube. The liposuction needle head is arc-shaped, the length is 100 mm-200 mm, the curvature radius is 120 mm-200 mm, and liposuction needle heads with different lengths and curvature radii can be used for different parts.

The other end of the liposuction needle head is connected with the sleeve. The sleeve is internally provided with a rubber plug, the center of the rubber plug is provided with a through hole, so that the guide needle head 5 passes through the rubber plug, the curvature radius of the guide needle head is matched with the liposuction needle head, and the length of the guide needle head is greater than that of the liposuction needle head. The guide needle head 5 and the guide needle seat are integrated, the guide needle seat is exposed outside the sleeve, and a through hole is arranged on the guide needle seat and communicated with the guide needle head. A hole is arranged on the side wall of the sleeve between the rubber plug and the joint of the liposuction needle and is connected with a drainage tube, so that the sucked fat is discharged through the drainage tube.

Preferably, the end of the liposuction needle is provided with a plurality of liposuction holes.

Preferably, the liposuction hole may be circular, oval, or the like.

Preferably, the liposuction needle is connected with the sleeve by screw threads.

The utility model has the advantages that:

(1) the plurality of liposuction holes at the tail end of the liposuction needle head improves the liposuction efficiency.

(2) The fat suction hole is round or oval, so that fat can enter the fat suction needle more smoothly.

(3) The liposuction needle head is connected with the sleeve pipe through threads, so that the connection stability is ensured, and the detachable function is realized.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

The sleeve type liposuction needle comprises a liposuction needle head 1, a liposuction hole 11, a sleeve 2, a guide needle seat 4, a guide needle head 5 and a drainage tube 6. The suction end of the liposuction needle head 1 is arc-shaped, the length is 100 mm-200 mm, the curvature radius is 120 mm-200 mm, and liposuction needle heads with different lengths and curvature radii can be used for different parts. The end of the liposuction needle 1 is provided with a plurality of liposuction holes 11, and the liposuction holes 11 can be round or oval and the like.

The other end of the liposuction needle 1 is connected with a sleeve 2. Be equipped with rubber buffer 3 in the sleeve pipe 2, rubber buffer 3 center is equipped with the through-hole, makes guide needle 5 pass rubber buffer 3, guide needle 5's curvature radius matches with liposuction needle 1, and length is greater than liposuction needle 1. The guide needle head 5 and the guide needle seat 4 are integrated, the guide needle seat 4 is exposed outside the cannula 2, and a through hole is arranged on the guide needle seat 4 and communicated with the guide needle head 5. A hole is arranged on the side wall of the sleeve 2 between the rubber plug 3 and the joint of the liposuction needle 1 and is connected with a drainage tube 6, so that the sucked fat is discharged through the drainage tube 6.

In use, the drainage tube 6 is connected to a negative pressure machine to extract fat. When fat farther away from the fat suction needle 1 needs to be extracted, the guide needle seat 4 can be connected with a small negative pressure machine, and the guide needle 5 with longer length is used for sucking the fat into the working range of the fat suction needle. In addition, in some operations, it is necessary to dissolve fat and then extract it, and the medicine may be injected through the guide needle 5 and then the fat may be sucked out through the liposuction needle 1.

It will be appreciated by those of ordinary skill in the art that the embodiments described herein are intended to assist the reader in understanding the principles of the invention, and it is to be understood that the scope of the invention is not limited to such specific statements and embodiments. Those skilled in the art can make various other specific modifications and combinations based on the teachings of the present invention without departing from the spirit of the invention, and such modifications and combinations are still within the scope of the invention.
