Description

Technical Field

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

[0002] The liposuction needle is used to suck out excess fat from a certain part of the body. The liposuction needle consists of a handheld tube, a puncture needle, a liposuction hole, a liposuction cavity, and a connector for connecting to a negative pressure suction tube. When sucking excess fat from a certain part of the human body, the doctor holds the handheld tube and connects the connector to the negative pressure suction tube. The negative pressure suction tube generates negative pressure by cooperating with the negative pressure vacuum suction device, and inserts the puncture needle into the subcutaneous fat layer. The doctor moves the liposuction needle back and forth in the fat layer through repeated piston movements to crush the fat cells. The negative pressure suction tube will suck the crushed fat cells out of the body through the liposuction hole and the liposuction cavity.

[0003] The inventor found in his daily work that when the liposuction needle is in use, in order to make the liposuction needle absorb fat more evenly, a liposuction cylinder with multiple groups of holes on the surface is installed on the surface of the puncture needle, thereby forming multiple channels for liposuction. Liposuction cylinders of different thicknesses can better absorb fat at different depths. However, since the liposuction cylinder is usually molded and fixed on the handheld tube together with the puncture needle, it is not easy to replace the liposuction cylinder. Utility Model Content

[0011] Preferably, a sealing ring is provided between the insertion tube and the connecting hole for sealing.

[0012] The effect achieved by the above components is: the insertion tube and the connecting hole are sealed by arranging the sealing ring.

[0015] Preferably, a bidirectional screw is provided on the inner wall of the slide groove, and the bidirectional screw is threadedly connected to the semicircular clamping ring.

[0016] The effect achieved by the above components is that the bidirectional screw rotates, causing the semicircular clamping rings in the slide grooves on both sides of the mounting plate to approach each other.

[0017] Preferably, the threads at both ends of the bidirectional screw are opposite, and a twisting block is fixedly connected to one side of the bidirectional screw.

[0018] The effect achieved by the above components is: twisting the twisting block causes the bidirectional screw to rotate, and twisting the twisting block can insert a long rod to increase the torque, thereby making it easier to tighten.

[0019] Preferably, the left end of the semicircular clamp ring on one side is fixedly connected to a circular rod, and the circular rod is slidably inserted into the other semicircular clamp ring.

[0020] The effect achieved by the above components is that the semicircular clamping ring is assisted in moving by arranging the circular rod.

[0021] In summary, the beneficial effects of the present invention are as follows:

[0022] In the utility model, a replacement component is provided. When the liposuction cylinder needs to be replaced, the limit ring on the fixing ring is pushed, and then the liposuction cylinder is pulled to push the small ball in the card slot to move outward, and then the new liposuction cylinder is sleeved on the arc surface of the puncture needle for fixation, thereby achieving the effect of facilitating the replacement of the liposuction cylinder as much as possible. The problem is that in order to make the liposuction needle absorb fat more evenly, a liposuction cylinder with multiple groups of holes on the surface of the puncture needle is installed, thereby forming multiple channels for liposuction, and liposuction cylinders of different thicknesses can better absorb fat at different depths. However, the liposuction cylinder is usually fixed on the handheld tube together with the puncture needle by a reverse mold, which makes it difficult to replace the liposuction cylinder.

[0031] Working principle:

[0032] When sucking excess fat from a certain part of the human body, the doctor holds the hand-held tube 1 and connects the connecting head 6 to the negative pressure suction tube. The negative pressure suction tube generates negative pressure by cooperating with the negative pressure vacuum suction device, and inserts the puncture needle 4 into the subcutaneous fat layer. The doctor moves the liposuction needle back and forth in the fat layer through repeated piston movements to crush the fat cells. The negative pressure suction tube will suck the crushed fat cells out of the body through the liposuction hole 5 and the liposuction cavity 7. When the liposuction cylinder 21 needs to be replaced, the limiting ring 26 on the fixing ring 23 is pushed, and then the liposuction cylinder 21 is pulled out to push the small ball 24 in the card slot 25 to move outward, and then the new liposuction cylinder 21 is sleeved on the arc surface of the puncture needle 4 for fixing, thereby achieving the effect of facilitating the replacement of the liposuction cylinder 21 as much as possible. By setting the spring 27, the limiting ring 26 is reset, and when the component 2 is replaced, the liposuction cylinder 21 is replaced. After replacing the liposuction tube 21, the connector 6 is connected to the negative pressure suction tube, and the insertion tube 28 is inserted into the connecting hole 210, so that the fat cells are sucked out through the suction holes 22 at different positions, thereby achieving multi-channel suction of fat cells, and then sucking fat at different depths more evenly. By setting the sealing ring 29, the insertion tube 28 and the connecting hole 210 are sealed. When it is necessary to fix the negative pressure suction tube to the connector 6, the negative pressure suction tube is inserted into the connector 6, and then the twisting block 35 is twisted to rotate the bidirectional screw 34. Twisting the twisting block 35 can insert a long rod to increase the torque, making it easier to tighten. The bidirectional screw 34 rotates, so that the semicircular clamping rings 33 in the slide grooves 32 on both sides of the mounting plate 31 are close to each other, thereby clamping and fixing the negative pressure suction tube. By setting the circular rod 36, the semicircular clamping ring 33 is assisted in moving.
