Description

Spoon-shaped grease injection needle

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a spoon-shaped grease injection needle.

Background

In recent years, with the improvement of living standard and the transformation of social value concept, people have more and more important to personal appearance condition, and the era of 'economy of color value' has come, and the medical beauty industry is rapidly developed. With the continuous development of medical beauty technology and the continuous improvement of the cognitive level of people, autologous fat filling technology is more and more developed. Autologous fat filling has been developed for nearly 50 years, and the main method is to suck fat particles from the redundant part of autologous fat, purify the fat particles, and inject and transplant the fat particles to the depressed part or the contour remodeling part needing to be filled. Through the establishment of blood supply at the fat later stage and the receptor region, the effects of remodeling the tissue appearance and filling the tissue recess can be achieved after survival. Is used for facial depression correction, chest hypopsia correction, bilateral breast asymmetry correction and improvement of fine superficial wrinkles, and has wide application prospect.

Autologous fat transplantation has several significant advantages: 1. the used fat particles are used as autologous tissues, the biological characteristics of the fat particles are far superior to those of any prosthesis materials, the fat particles are non-toxic and harmless to the fat particles, and immune reaction and rejection reaction can not be generated; 2. the autologous fat transplantation does not cause the change of the endocrine environment of the human body and has no adverse effect; 3. the autologous fat particles are used as filling materials, so that the materials are easily obtained from the autologous fat particles, and the tissue source is rich. Fat filling, however, has the disadvantage that a certain degree of absorption is possible after transplantation, often requiring re-surgery to ensure the best results. Therefore, how to ensure the integrity and activity of the fat particles as much as possible during filling plays a decisive role in the filling effect of the fat.

With the continuous development of fat transplantation technology, various types of fat injection needles are used. However, the conventional fat injection needle is only provided with one or more fat injection holes on the needle body, so that fat particles can be pushed and injected into tissues to be filled by using larger pressure, the fat filling efficiency is greatly reduced, and a great amount of time is spent by an operator especially in parts needing a large amount of autologous fat for filling, such as breasts, buttocks and the like; and the fat particles are forced to extrude out of the tube cavity by the pressure generated by the injection device, so the integrity and the activity of the fat particles can be damaged in different degrees, and the whole effect of fat filling can be influenced in different degrees

SUMMERY OF THE UTILITY MODEL

The main technical problem to be solved by the utility model is to overcome the defects of the prior fat injection needle, for example, the prior fat injection needle is only provided with one or more fat injection holes on the needle body, so that fat particles can be pushed and injected into tissues to be filled by often needing larger pressure, the fat filling efficiency is greatly reduced, and a great amount of time is spent by operators especially at the parts needing a great amount of autologous fat for filling, such as chest, hip and the like; and the fat particles are forced out of the lumen by the pressure generated by the bolus injection, so the integrity and activity of the fat particles are damaged to different degrees, and the overall effect of fat filling is also affected to different degrees. Thereby providing a spoon-shaped greasing needle.

The technical scheme of the utility model realize the route as follows:

the utility model provides a fat needle is annotated to spoon form, wherein, includes needle file and the stainless steel needle body of integrated into one piece who is connected with the needle file, the needle body is inside to be cavity, needle body head end department is a soup spoon column structure of transition naturally along the direction of needle body major axis, soup spoon column structure is solid construction in needle body head end department, soup spoon column structure is equipped with one on the needle body major axis towards the needle file direction and annotates the fat hole, just the length of annotating the fat hole is 2.4 ~ 5.6mm, and the width is 1.2 ~ 2.8 mm.

Through the structure, after the injector connected with the tail end of the needle seat starts to inject, the fat particles required by autologous fat transplantation can smoothly flow out through the fat injection hole, the pressure required by injection is obviously reduced, more fat particles can be injected in a short time, and the operation time can be obviously shortened especially in parts needing a large amount of autologous fat for filling, such as breasts, buttocks and the like; and because the fat particles smoothly flow out from the fat injection hole and no obvious resistance is met in the process of injecting the fat particles, the integrity and the activity of the fat particles can be better ensured, thereby greatly increasing the survival rate of the fat particle cells after the operation.

Preferably, one end of the solid structure of the spoon-shaped structure at the needle body head end along the needle seat direction is arc-shaped, and the other end extends to be the needle body head end.

Preferably, the length of the solid structure is 3.0mm, and the width of the solid structure is 1.2-2.8 mm.

Preferably, one end of the long shaft of the needle body, facing the direction of the needle seat, of the grease injection hole is in a naturally transitional arc shape, and the other end of the long shaft of the needle body extends to form an arc end with a solid structure.

Preferably, the length of the needle body is 100-250 mm, and the diameter of the needle body is 1.4-3.0 mm.

Preferably, the head end of the needle body is a blunt blind end, so that the needle body can easily penetrate through soft tissues, meanwhile, the damage to peripheral blood vessels can be better avoided, and the nutrition supply of fat particles injected into the tissues is ensured to a greater extent.

Preferably, the distance between the grease injection hole and the head end of the needle body is 3 mm;

preferably, the needle body is made of medical 316L stainless steel thin-walled tubing.

The utility model discloses technical scheme's beneficial effect is: through the design of the spoon-shaped structure, after the injector connected with the tail end of the needle seat starts to inject, the fat particles required by autologous fat transplantation can smoothly flow out through the fat injection hole, the pressure required by injection is obviously reduced, more fat particles can be injected in a short time, and the operation time can be obviously shortened especially in parts needing a large amount of autologous fat for filling, such as breasts, buttocks and the like; and because the fat particles smoothly flow out from the fat injection hole and no obvious resistance is met in the process of injecting the fat particles, the integrity and the activity of the fat particles can be better ensured, thereby greatly increasing the survival rate of the fat particle cells after the operation.
