[0001] The utility model relates to the field of medical instruments, in particular to a needle for fat surgery. Background Art

[0002] A fat surgery needle is a medical tool used to extract fat. This needle is usually made of a thin and long metal with a smooth surface to reduce damage to the tissue while maintaining the integrity of the surrounding tissue. When used, the doctor will use this needle to pierce the patient's body and extract the fat tissue. This surgical needle is widely used in the field of cosmetic surgery, such as liposuction and autologous fat filling, to help patients achieve body shaping and beauty effects;

[0003] In order to adapt to different surgical needs, doctors may need to frequently remove and replace needles with different side holes. This process is cumbersome and time-consuming, which may prolong the overall operation time. Secondly, the adjustment of the needle length is also inconvenient. The existing design often does not provide enough fine-tuning space, which means that doctors may not be able to accurately control the depth of the needle into the skin, which may affect the accuracy of the operation and the patient's postoperative recovery. These problems not only affect the efficiency of the operation, but may also have an adverse effect on the surgical results. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, a needle for fat surgery includes a fixing seat 1, an adjusting mechanism 2 is provided on the top of the fixing seat 1, the adjusting mechanism 2 includes a knob 3, the bottom of the knob 3 is rotatably connected to the center position of the inner side of the fixing seat 1, a suction tube 4 is provided on one side of the fixing seat 1, a spring 5 is movably connected to the bottom of the fixing seat 1, a sleeve 6 is movably connected to the bottom of the spring 5, a guide sleeve 10 is provided on the inner side of the sleeve 6, an outer tube 7 is movably connected to the inner side of the guide sleeve 10, an inner tube 8 is slidably connected to the inner side of the outer tube 7, a fixing tube 9 is rotatably connected to the inner side of the inner tube 8, a telescopic tube 11 is rotatably connected to the fixing tube 9 on the inner side of the inner tube 8, the top of the telescopic tube 11 is slidably connected to the fixing tube 9, and the top of the fixing tube 9 is fixedly connected to the bottom of the fixing seat 1 near the inner side of the outer tube 7.

[0023] In this embodiment, a screw rod 13 is provided at the bottom of the knob 3 , the outer side of the screw rod 13 is meshedly connected with a threaded block 12 , and the outer side of the threaded block 12 is fixedly connected with the telescopic tube 11 .

[0024] The screw rod 13 can be driven to rotate by rotating the knob 3 , and the screw rod 13 can drive the threaded block 12 to move through the thread during the rotation process.

[0025] In this embodiment, a screw hole is opened at the top of the threaded block 12 and passes through to the bottom, support rods are symmetrically provided at the front and rear of the threaded block 12, a round rod is provided at the bottom of the knob 3 above the screw rod 13, and a circular protrusion is provided at the bottom of the round rod, and a through hole is opened at the top of the fixing seat 1 and passes through to the bottom.

[0026] The threaded block 12 can be driven by the screw rod 13 and drive the telescopic tube 11 to move during the movement.

[0027] In this embodiment, long grooves are formed on both sides of the outer tube 7 , and two cylindrical protrusions are formed on the top of the outer tube 7 .

[0028] The outer tube 7 is connected to the guide sleeve 10 via a cylindrical protrusion at the top, and the guide sleeve 10 can rotate the outer tube 7 by squeezing the cylindrical protrusion.

[0029] In this embodiment, two semicircular plates are provided on the top of the inner tube 8, and the bottom of the inner tube 8 is hemispherical.

[0030] The inner tube 8 can wrap the telescopic tube 11 through two semicircular plates, and the hemispherical bottom can reduce puncture damage to the patient.

[0031] In this embodiment, an annular groove is formed on the inner side of the inner tube 8 , an annular protrusion is formed on the top of the telescopic tube 11 , two block-shaped protrusions are formed on the top of the telescopic tube 11 , and two sliding grooves are formed on the inner side of the fixed tube 9 .

[0032] The inner tube 8 is connected to the annular protrusion of the telescopic tube 11 through an annular groove. When the telescopic tube 11 is extended or retracted, the inner tube 8 can be driven to extend or retract together. The fixed tube 9 constrains the movement freedom of the telescopic tube 11 through the sliding groove so that it can only move along a straight line.

[0033] In this embodiment, a plurality of circular holes and a plurality of triangular holes are formed on the outer side of the fixed tube 9 , and a plurality of circular holes and a plurality of triangular holes are formed on the outer side of the telescopic tube 11 as well.

[0034] By connecting a negative pressure gas source to the suction tube 4 , fat can be sucked out through the holes of the inner tube 8 and the outer tube 7 .

[0035] It should be noted that the utility model is a needle for fat surgery, which can adjust the length and quickly replace different side holes during use, so that different side holes can be quickly replaced during surgery to meet different usage requirements, and the adjustable length can increase the applicability of the needle for fat surgery;

[0036] When replacing the side hole, the specific implementation method is to move the sleeve 6 upward, and the sleeve 6 moves while driving the guide sleeve 10 to move upward, and squeeze the spring 5 to store force. When the guide sleeve 10 moves upward, it squeezes the cylindrical protrusion on the top of the outer tube 7 through its own groove, so that the outer tube 7 rotates. When the outer tube 7 rotates, the inner tube 8 is driven to rotate together through the connection between the bottom and the inner tube 8. The inner tube 8 and the outer tube 7 are rotated 90° by the guidance of the groove of the guide sleeve 10;

[0037] After the inner tube 8 and the outer tube 7 rotate, their grooves will be aligned with different holes of the fixed tube 9 and the telescopic tube 11, and the other holes of the fixed tube 9 and the telescopic tube 11 will be blocked. Then, the sleeve 6 is released, and the sleeve 6 is reset under the action of the spring 5. By moving the sleeve 6 up again, the inner tube 8 and the outer tube 7 can be rotated again. By switching different side holes, it can adapt to different situations encountered during surgery, reduce the time of disassembling and replacing other needles, and improve the efficiency of surgery.

[0038] When the length of the needle needs to be adjusted, the specific implementation method is to rotate the knob 3. When the knob 3 rotates, the screw rod 13 is driven to rotate. When the screw rod 13 rotates, the threaded block 12 is driven to move through the thread. When the threaded block 12 moves, the telescopic tube 11 is driven to move together. Since the telescopic tube 11 is constrained by the fixed tube 9, it does not have the freedom of rotation and can only move along the axis of the screw rod 13. By rotating the knob 3 in different directions, the moving direction of the telescopic tube 11 can be controlled, thereby adjusting the length of the needle for fat surgery, so as to adapt to different surgical needs and increase the applicability of the needle for fat surgery.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
