Unless specifically stated otherwise, the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Figure 1 shows a schematic side view of a liposuction needle according to an exemplary embodiment of the present invention. As shown in fig. 1, the liposuction needle includes a needle holder 1 and a cylindrical elongated needle tube 2. The hub 1 centrally comprises a grease outlet (not shown) through the hub 1. The needle cannula 2 centrally comprises a cylindrical lumen (not shown). One end of the needle tube 2 is connected with the needle base 1, and the other end is a beveled opening end. The needle tube 2 can be connected with the needle base 1 by welding and the like, and can also be integrally formed with the needle base 1. The lumen of the needle tube 2 is communicated with the grease discharging port of the needle base 1. The tube wall of the needle tube 2 is provided with a pair of liposuction holes 3, and the pair of liposuction holes 3 are symmetrically arranged about the axis of the needle tube 2 (as shown in fig. 1, two liposuction holes 3 are opposed to each other on both sides of the tube wall to form a pair of holes). The liposuction hole 3 penetrates the wall of the needle tube 2 so as to communicate with the lumen of the needle tube 2.
In operation, the needle cannula 2 is inserted into adipose tissue and fat particles enter the lumen through the beveled open end and the liposuction aperture 3 and are expelled through the liposuction port of the needle hub 1. Compared with the blunt-end blind-end liposuction needle in the prior art, one end of the liposuction needle for inserting adipose tissues is designed to be in a bevel shape, so that the liposuction needle is convenient to insert and pass through the adipose tissues, the needle insertion is fast, and the liposuction efficiency is high. In addition, in the prior art, fat particles can only enter the liposuction needle through a single hole on the side surface of the liposuction needle, but in the invention, the fat particles can enter the liposuction needle through the opening of the obliquely cut open end and the hole pairs on the two sides of the liposuction needle, so the liposuction efficiency is high, the liposuction needle is suitable for liposuction of a body, is convenient for liposuction and liposuction of large area, and is not easy to block.
Figure 2 shows a schematic perspective view of a liposuction needle according to an exemplary embodiment of the present invention. As shown in fig. 1 and 2, in one embodiment of the present invention, the hole wall 4 of the liposuction hole 3 is provided as a curved surface recessed toward the lumen of the needle tube 2. For example, the hole wall 4 of the liposuction hole 3 may be a curved surface formed by intersecting a virtual cylindrical surface, the axis of which is located outside the needle cannula 2 and is perpendicular to the axis of the needle cannula 2, with the wall of the needle cannula 2. The inward concave arc design of the liposuction hole 3 can protect the taken fat cells from being damaged and keep original ecology.
Preferably, the pair of liposuction holes 3, which are symmetrically arranged, have the same shape and the same size, thereby facilitating the uniform and symmetric suction of fat on both sides of the liposuction needle.
Figure 3 shows a schematic front view of a liposuction needle according to an exemplary embodiment of the present invention. As shown in fig. 3, the liposuction hole 3 may be an elliptical hole, but is not limited thereto. For example, the liposuction hole 3 may also be a water drop-shaped hole, a kidney-shaped hole, or the like.
In one embodiment, the liposuction orifice 3 is an orifice having an aspect ratio greater than 1 (as shown in FIG. 3). The longitudinal direction of the liposuction hole 3 is arranged along the axial direction of the needle tube 2. That is, the ratio of the bore diameter of the liposuction bore 3 in the axial direction of the needle tube 2 to the bore diameter thereof in the circumferential direction of the needle tube 2 is larger than 1, preferably 1.5 to 3.
In one embodiment, as shown in fig. 1 and 3, when the liposuction needle is vertically placed with the beveled open end facing upward, a pair of liposuction apertures 3 are located directly below the highest point and directly below the lowest point of the beveled open end, respectively.
In one embodiment, the needle cannula 2 is provided with a titanium nitride coating on its surface. The titanium nitride coating can reduce the friction coefficient on the surface of the liposuction needle, reduce the resistance of the liposuction needle when entering the body and further reduce the wound.
In one embodiment, the liposuction aperture 3 is positioned near the beveled open end of the needle cannula 2. Preferably, the distance between the one of the pair of grease suction holes 3 closer to the chamfered open end (the grease suction hole 3 on the right side in fig. 1) and the chamfered open end is not more than 10 mm.
In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, and in the case of not making a contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be interpreted as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.
Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and if not stated otherwise, the terms have no special meaning, and therefore, the scope of the present invention should not be construed as being limited.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
