Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a rotary cutting head structure that facilitates penetration of the dense tissue of a flat, fleshy lumps. Background Art

[0002] A "dowager's hump" refers to a hard lump that protrudes from the cervical-thoracic junction of the upper back, specifically between the seventh cervical vertebra and the first thoracic vertebra. This lump contains not only fatty tissue but also a large amount of overgrown fibrous connective tissue. When the dowager's hump is severe or rapid elimination is desired, manual liposuction can be performed on the neck and back area. The medical instrument used in the procedure is a negative-pressure electric rotary scalpel. This scalpel has a double-layered needle structure; the outer layer is typically a non-rotating stainless steel tube, while the inner layer is a rotating blade with negative pressure suction. During the procedure, the electric rotary scalpel is inserted into the dowager's hump, and the rotating blade breaks down the fatty and fibrous connective tissue. The broken tissue is then extracted using negative pressure. Because the end of the electric rotary scalpel that inserts into the body is flat, it is difficult to penetrate dense connective tissue. Furthermore, the blade only has one opening at the insertion point, and negative pressure suction can easily create localized grooves in the subcutaneous tissue at this opening, resulting in uneven internal tissue. Summary of the Invention

[0003] The purpose of this invention is to provide a rotary cutting head structure that solves the above problems, saves time and effort during surgery, and is less likely to cause unevenness in subcutaneous tissue. This structure facilitates the penetration of the dense tissue of a flat, fleshy lumps.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rotary cutting head structure that facilitates penetration of the dense tissue of a flat, swollen liposuction bun, comprising a horizontally arranged double-layer tube structure. The double-layer tube structure includes an outer tube body and a tubular rotating cutting head located inside the outer tube body. The rotating cutting head is connected to a driving mechanism that drives its rotation and is also connected to a negative pressure liposuction machine. The end of the double-layer tube structure that pierces the skin is the front end face, which is a bevel. Near the front end face, the rotating cutting head has several first through holes arranged alternately. The outer tube body has a second through hole corresponding to the first through hole.

[0005] Preferably, the outer tube and the rotating cutter head are both made of stainless steel.

[0006] Preferably, the inclined plane has an inclination angle of 25° to 35° and a length of 0.5cm to 1.5cm.

[0007] Preferably, the inclined plane has an inclination angle of 30° and a length of 1cm.

[0008] Preferably, the diameters of the first and second through holes are 3mm-5mm.

[0009] Compared with the prior art, the advantages of this utility model are: (1) The front end face of the needle inserted into the skin is changed from a plane to a bevel, which is more conducive to penetrating the dense fibrous connective tissue in the dowager's hump, and the operation is more time-saving and labor-saving. (2) Multiple first through holes and second through holes are set on the side wall of the rotating blade and the side wall of the outer tube near the front end face. Since these through holes are staggered, subcutaneous tissue can be sucked up from multiple different angles and broken up by the rotating blade, avoiding the unevenness of the tissue caused by only one entrance. Finally, the suction efficiency is high and the tissue is processed smoothly during the operation. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] Example 1: See Figure 1 and Figure 2 A rotary cutting head structure that facilitates penetration of the dense tissue of a flat, swollen liposuction bun includes a horizontally arranged double-layer tube structure. The double-layer tube structure includes an outer tube body 1 and a tubular rotating cutting head 2 located inside the outer tube body 1. The rotating cutting head 2 is connected to a drive mechanism that drives its rotation and is also connected to a negative pressure liposuction machine. The end of the double-layer tube structure that pierces the skin is a front end face 3, which is a bevel. Near the front end face 3, the rotating cutting head 2 has several first through holes 4 arranged alternately. The outer tube body 1 has a second through hole 5 corresponding to the first through holes 4.

[0015] Both the outer tube 1 and the rotating cutter head 2 are made of stainless steel. The inclined plane has an angle of 25° to 35° and a length of 0.5cm to 1.5cm. The diameters of the first through hole 4 and the second through hole 5 are 3mm to 5mm.

[0016] This utility model relates to the blade head structure of a negative pressure electric rotary scalpel. The blade head 2 is mounted on a negative pressure electric rotary scalpel, and is driven by a drive mechanism to rotate along a central axis, and is connected to a negative pressure liposuction machine. The blade head 2 is mounted on this utility model... Figure 2Based on existing technology, improvements have been made. Not only has the front end face 3 been changed to a bevel, but multiple first through holes 4 and second through holes 5 have also been set. During operation, the doctor holds a negative pressure electric rotating blade and inserts it into the body part to be treated. The negative pressure liposuction machine generates negative pressure, and fat tissue or connective tissue enters the rotating blade head 2 from multiple angles, such as the front end face 3, the first through hole 4, and the second through hole 5. The rotating blade head 2 rotates and breaks down these tissues, which are then sucked away by the negative pressure.

[0017] Example 2: See Figure 1 The inclined plane has an angle of 30° and a length of 1 cm. Everything else is the same as in Example 1.

[0018] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
