Detailed Description

The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.

As shown in fig. 1, 2 and 4, the embodiment of the utility model provides a leg liposuction needle, which comprises a needle tube body 1, wherein a conical advance part 12 is arranged at the needle end of the needle tube body 1, a plurality of needle holes 11 which are uniformly distributed are formed in the needle tube body 1, and the needle holes 11 are of a diameter-changing hole structure which is contracted and enlarged in the axial direction. The needle hole 11 comprises a shrinkage cavity 111, a buffer cavity 112 and a flaring cavity 113 according to the axial direction of the needle hole, the shrinkage cavity 111, the buffer cavity 112 and the flaring cavity 113 form a shrinkage-before-enlarging reducing hole structure, the structure of the needle hole 11 is changed, and fat similar to fluid is easier to pass through the needle hole 11 and enter the needle tube body 1. When the needle tube is particularly used, the first part 12 is conical, so that the small-area separation of the fat layer can be facilitated, and fat can enter the needle tube body 1 through the needle hole 11 under the action of negative pressure; the needle hole 11 with a columnar structure is changed into a reducing hole structure which is contracted before enlarged, so that the needle hole 11 is approximately in an hourglass shape, when fat outside the needle tube body 1 contacts the needle hole 11 and is sucked along the needle hole 11 to cover the needle hole 11, similar fluid flows along the needle hole 11, pressure difference is generated at two ends of the needle hole 11 when the fluid passes through the structure which is contracted before enlarged through Bernoulli's theorem restriction, the pressure difference can provide additional suction force for the fat under the action of negative pressure connected with the needle tube body 1, the fat can pass through the needle hole 11 to enter the needle tube body 1 at a higher entering speed, the fat can be further smoothly guided into the needle tube body 1 to be led out from the needle tube body 1, and the fat is easier to be led out when the fat is pumped from a thicker part of a fat layer such as a leg part by matching with the action of the leading part 12, and the use effect of the fat suction needle is better.

As shown in fig. 1, 2 and 3, since the liposuction needle provided by the utility model is mainly used for the parts with thicker fat layers such as legs, the length of the liposuction needle used for the parts is generally longer than that of the parts with thinner fat layers such as faces, and the structure which can be used for applying force to rotate the needle tube body 1 is not arranged outside the prior needle tube body 1, so that the liposuction needle with longer length does not rotate in the use process, in order to solve the problem, the utility model is provided with the anti-skid holding part 2 outside the needle tube body 1, wherein the anti-skid holding part 2 comprises the fixed sleeve 22 annularly arranged along the needle tube body 1 and a plurality of anti-skid strips 21 annularly arranged along the fixed sleeve 22, and each anti-skid strip 21 is axially extended along the fixed sleeve 22.

The anti-slip holding part 2 is arranged to enable a part which is easier to apply acting force to be attached to the outside of the needle tube body 1, meanwhile, due to the arrangement of the anti-slip strips 21, the whole anti-slip holding part 2 can be easily held, has an anti-slip effect when being contacted with hands of an operator, enables the operator to rotate, move and other operations more easily when in use, and enables the liposuction needle arranged by the utility model to be more convenient to use.

As shown in fig. 2 and 3, the liposuction needle is generally a disposable article, and is strictly sterilized before being sold, and packaged and sold after being sterilized, and due to the arrangement of the plurality of anti-slip strips 21, disinfectant which is not easy to dry may exist in gaps between the anti-slip strips 21, and in order to facilitate rapid guiding out of the disinfectant between the plurality of anti-slip strips 21, the fixing sleeve 22 comprises a mounting part with a conical frustum shape, and the large end face of the mounting part is arranged towards the needle end of the needle tube body 1. The anti-slip strip 21 is in a right trapezoid structure, and the bevel edge of the anti-slip strip 21 is fixed with the fixed sleeve 22. The setting of installation department, cooperation trapezium structure's antislip strip 21 for the guiding gutter that forms between the adjacent antislip strip 21 all has certain difference in height at the both ends under the horizontality, can be favorable to the antiseptic solution in the guiding gutter to lead out, avoids influencing the production efficiency of liposuction needle because of the antiskid grip 2 that adds.

Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present utility model, which is intended to be covered by the scope of the claims of the present utility model.
