Description

Technical Field

[0001] The utility model relates to the technical field of needles, in particular to a quick-connect liposuction needle. Background Art

[0002] As people's living standards continue to improve, the number of obese people continues to increase. In order to maintain their figure, some people go to the hospital for liposuction surgery. Liposuction is the use of instruments through the skin incision to reach the subcutaneous fat layer to suck out fat fragments to achieve the purpose of absorbing fat. Liposuction needles are often used in liposuction surgery. However, the existing liposuction needles have the following shortcomings when used:

[0003] 1. Most liposuction needles are installed on liposuction cylinders by means of threaded connections. Since the overall size of the liposuction needle is relatively thin, installation and disassembly are inconvenient.

[0004] Therefore, we propose a quick-connect liposuction needle. Utility Model Content

[0005] The utility model aims to solve the problem that most liposuction needles in the prior art are installed on liposuction cylinders by threaded connection, and the installation and disassembly are inconvenient due to the thin overall size of the liposuction needles, and proposes a quick-connect liposuction needle.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A quick-connect liposuction needle, comprising:

[0008] A liposuction cylinder body, wherein a suction nozzle is integrally formed at the bottom end of the liposuction cylinder body;

[0009] The mounting sleeve is threadedly connected to the bottom end of the liposuction barrel body, the suction nozzle is located in the mounting sleeve, the bottom end of the mounting sleeve is provided with two symmetrically arranged positioning grooves, the outer wall of the mounting sleeve is rotatably connected with an adjustment sleeve, the bottom end of the adjustment sleeve is provided with two grooves, one side of the two grooves is integrally formed with a card block, and a torsion spring is fixed between the adjustment sleeve and the mounting sleeve;

[0010] A connecting tube is installed between the suction nozzle and the mounting sleeve. A liposuction needle is fixed to the bottom end of the connecting tube. The outer wall of the connecting tube is integrally formed with two symmetrically arranged positioning blocks, the positioning blocks and the positioning grooves are adapted to each other, and a card slot is penetrated through one side of the positioning block, and the card slot and the card block are adapted to each other.

[0011] In a possible design, an elastic block is slidably connected to the inner wall of the mounting sleeve, a spring is fixed between the elastic block and the mounting sleeve, and the elastic block and the connecting pipe are in conflict with each other.

[0012] In a possible design, a sealing ring is provided on the inner wall of the connecting pipe, and the sealing ring and the suction nozzle are in conflict with each other.

[0013] In a possible design, at least two protrusions are integrally formed on the outer wall of the adjustment sleeve, and the protrusions are distributed at equal angles around the adjustment sleeve.

[0014] In a possible design, second guide surfaces are provided at the bottom ends of both sides of the positioning groove.

[0015] In a possible design, the bottom of each of the clamping blocks is provided with a first guiding surface, and both the first guiding surface and the second guiding surface are configured as inclined surfaces or arc surfaces.

[0016] In a possible design, a limiting groove is provided at the bottom end of the adjustment sleeve, and a limiting block is integrally formed on the outer wall of the mounting sleeve, and the limiting block and the limiting groove cooperate with each other.

[0017] In a possible design, a plurality of anti-slip grooves are formed on the outer wall of the mounting sleeve.

[0018] In the present application, when installing the liposuction needle, align the positioning block and the positioning groove, insert the connecting tube into the installation sleeve, and during the movement of the connecting tube, the positioning block contacts the first guide surface and pushes the clamping block to rotate, thereby driving the adjusting sleeve to rotate, and when the clamping groove and the clamping block are aligned, the torsion spring drives the adjusting sleeve to reset, so that the clamping groove and the clamping block are docked, at which time the suction nozzle and the sealing ring are in conflict, and the connecting tube pushes the spring block to move so that the spring is compressed;

[0019] When removing the liposuction needle, use the convex block to move the adjusting sleeve to rotate. With the cooperation of the limit groove and the limit block, the adjusting sleeve can only rotate to a specific angle, so that the adjusting sleeve drives the card block to just leave the card groove, and the positioning block will not be squeezed by the other side of the groove, that is, the positioning block will not be squeezed by the adjusting sleeve, which makes it convenient for the spring to push the spring block to move, and then it is convenient to directly pop out the connecting tube and the liposuction needle.

[0020] Beneficial effects:

[0021] In the utility model, the quick-connect liposuction needle can be quickly installed and disassembled through the arrangement of multiple structures such as the positioning groove, the positioning block, the clamping groove and the clamping block, and the operation is simple and fast, and the use is more convenient;

[0022] In the utility model, the quick-connect liposuction needle can limit the adjustment sleeve by setting the limit groove and the limit block, so that the positioning block can stably contact the first guide surface, which is convenient for people to install the liposuction needle, and can avoid people from excessively rotating the adjustment sleeve, and can facilitate the elastic block to eject the connecting tube;

[0023] In the utility model, the quick-connect liposuction needle can automatically eject the connecting tube and the liposuction needle when the liposuction needle is disassembled by setting the spring and the elastic block, which provides convenience for disassembling the liposuction needle.

[0024] In the utility model, the adjustment sleeve can be limited, so that the positioning block can stably contact with the first guide surface, and the liposuction needle can be automatically ejected, so that people can quickly install and disassemble the liposuction needle, the operation is simple and fast, and the use is more convenient.
