[0028] In the embodiment of the present application, the cutting portion 2 may include two spiral blades 2, and the spiral directions of the two spiral blades 2 are opposite, and the spiral blades 2 are intertwined with each other to form a scissors shape at the distal end, which refers to the side away from the rotating rod 1.
[0029] It can be understood that the cutting part may also include a plurality of spiral blades 2, and the plurality of spiral blades 2 may be arranged in sequence in a spiral shape along the axis, and there may be a cutting gap between adjacent spiral blades 2, so as to be used for cutting the connective tissue and excess fat at the cutting position.
[0030] The spiral blade 2 is provided with a first cutting edge 22 and a second cutting edge 23 on both sides along the length direction. Specifically, a step structure can be provided on both sides of the spiral blade 2, and the edge of the step structure is treated with a blade. By providing a double blade, the spiral blade 2 can cut connective tissue and excess fat when rotating clockwise or counterclockwise, thereby improving the cutting range and cutting efficiency.

[0032] As an embodiment, the total length of the rifle can be 150 mm, the diameter can be 5 mm or 7 mm, and the length of the spiral cutter 2 can be 30 mm.
[0033] It is understandable that the diameter of the rotary rod 1 is less than or equal to the maximum diameter of the cross section of the cutting portion, so as to avoid the rotary rod 1 having an excessively large diameter, requiring a larger blade, or causing secondary damage to the blade when reciprocating or rotating.
[0034] The rotating rod 1 can be made of metal.
[0035] In one embodiment of the present application, the rotating rod 1 can be a solid structure, and an operating handle 3 is provided on the other side of the rotating rod 1 away from the cutting part. When in use, the user can hold the operating handle 3 to control the rotating rod 1 to move back and forth and rotate, so that the connective tissue and excess fat at the cutting position to be cut can be cut by the spiral cutter 2. After the cutting is completed, the removed tissue can be expelled from the body by squeezing or liposuction equipment, thereby achieving the removal of the gynecomastia.
[0036] The operating handle 3 is provided with anti-skid patterns to increase friction and avoid the situation of falling or being unable to hold it firmly during use, which may cause safety problems.
[0037] The operating handle 3 may be 70 mm long, and the solid rotary rod may be 120 mm long.
[0038] The operating handle 3 and the rotating rod 1 may be an integrally formed structure.
[0039] In one embodiment of the present application, the rotary rod 1 may be a hollow structure. Specifically, an adsorption chamber 11 may be provided in the rotary rod 1, and an adsorption hole (not shown in the figure) may be provided on one side of the rotary rod 1 close to the cutting portion 2, and the adsorption chamber 11 is connected to the adsorption hole. It can be understood that a receiving gap 24 may be formed between adjacent spiral cutters 2 to receive the material cut by the spiral cutters 2, and the adsorption hole may be connected to the receiving gap 24 to absorb the material received in the receiving gap 24 to discharge it out of the body.
[0040] In one embodiment of the present application, the end of the rotary rod 1 away from the cutting part is detachably connected to an absorber 4, and the absorber 4 is in communication with the absorber chamber 11, and is used to generate a negative pressure environment to absorb the material cut by the cutting part 2. Specifically, the connective tissue and fat at the cutting position are cut and mashed by the cutting part, and then the absorber 4 is started to suck away the air, thereby generating a negative pressure environment, so that the excised material is adsorbed into the absorber chamber through the adsorption hole and discharged from the body, so that the excised material can be adsorbed while cutting, without the need to replace the adsorption equipment, and the excised material can be prevented from affecting the cutting part 2, thereby improving the cutting efficiency.
[0041] The adsorber 4 may be a negative pressure generating device for generating negative pressure by compressed air.
[0042] In the embodiment of the present application, a gripping portion (not shown in the figure) may be provided on the side of the rotary rod 1 away from the cutting portion, and the user can pull or rotate the gripping portion to achieve reciprocating movement and rotation of the cutting portion.

Specifically, the rotary rod 1 may be provided with a collection hole (not shown in the figure), which is connected to the adsorption cavity. When the spiral cutter 2 cuts and crushes the connective tissue and fat, the adsorption force provided by the adsorber 4 can be used to adsorb them into the adsorption cavity, and flow into the collection box through the collection hole to prevent the cut substances from clogging the adsorption cavity.
[0049] In one embodiment of the present application, the rifle further includes: a telescopic assembly (not shown in the figure), one end of which is connected to the rotary rod 1, and the other end of which is connected to the cutting part, and can be used to adjust the cutting depth of the cutting part, that is, the length of the cutting part extending into the position to be cut. Specifically, the telescopic assembly can be arranged inside the rotary rod 1, and the power output end of the telescopic assembly can be connected to the cutting part, and can be extended and retracted a certain distance under the drive of the telescopic assembly to adjust the cutting depth of the cutting part, which can increase the cutting range and avoid opening a larger surgical wound, so as to improve the cutting efficiency and facilitate later recovery.
[0050] The telescopic component may be a power structure such as a cylinder or a motor.
[0051] In the embodiment of the present application, when in use, the cutting portion can be extended into the surgical site, and the user can drive the cutting portion to rotate and move it back and forth by rotating the rotary rod and pulling it back and forth, so as to achieve the removal of the connective tissue and fat of the ganglion by the spiral blade. By manually controlling the removal position and removal depth of the spiral blade, the nerves or other tissues around the surgical site can be prevented from contacting the blade, which can reduce damage to the nerve network and improve surgical safety. The surgical trauma is small and later recovery is facilitated. In addition, by setting the spiral blade to a spiral shape and setting the distal end to a pointed portion, double cutting in the horizontal and vertical directions can be achieved, and the connective tissue and fat can be removed from multiple directions, resulting in a better cutting effect.
[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
