DETAILED DESCRIPTION

[0029] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0030] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations such as "include" or "comprising", etc., will be understood to include the stated elements or components but not to exclude other elements or other components.

[0031] Reference Figures 1-10 The breast tumor cutter of the present invention includes a gripping sleeve 1, and a rotating structure 2 is installed at the tail of the gripping sleeve 1. In this specification, the left side of the drawings is the head end, and the right side is the tail end. A grasping and cutting structure 3 is provided inside the gripping sleeve 1.

[0032] In the present invention, the gripping sleeve 1 includes a sleeve 11 with a hollow cylindrical structure and a movable sleeve 12 sleeved on the outside of the sleeve 11. A through cavity 111 is opened inside the sleeve 11, and a port 112 is opened at the head end of the through cavity 111. The port 112 is a trumpet-shaped structure. The grabbing and cutting structure 3 passes through the through cavity 111, so that the grabbing and cutting structure 3 is sleeved inside the gripping sleeve 1.

[0033] Specifically, an annular groove 113 is formed on the outer surface of the gripping sleeve 1. The movable sleeve 12 is mounted in the annular groove 113 and is rotatably connected to the sleeve 11, allowing the sleeve 11 to rotate around the axis of the movable sleeve 12. An anti-slip rubber sleeve 121 is mounted on the outer surface of the movable sleeve 12. When the surgeon grips the movable sleeve 12 with their hands, the anti-slip rubber sleeve 121 enhances the anti-slip effect.

[0034] A threaded boss 114 is integrally formed at the rear end of the sleeve 11. The outer surface of the threaded boss 114 is threaded. Several levers 115 are integrally formed on the outer surface of the rear end of the sleeve 11. When the surgeon holds the movable sleeve 12 with one hand, they can use their other hand to move the levers 115, causing the levers 115 to drive the sleeve 11 to rotate within the movable sleeve 12. Several anti-slip protrusions 116 are integrally formed on the outer surface of the front end of the sleeve 11. When the surgeon's hand holding the movable sleeve 12 overlaps the anti-slip protrusions 116 and the movable sleeve 12, the movable sleeve 12 and the sleeve 11 can form an integrated structure under the grip of the hand, so that the movable sleeve 12 is in a stopped state.

[0035] In the above scheme, the rotating structure 2 includes a sleeve 21 threadedly connected to the tail end of the gripping sleeve 1 and a rotating seat 22 rotatably connected to the tail end of the sleeve 21. A through hole 211 is provided on the tail end face of the sleeve 21, and a threaded cavity 212 is provided on the head end face of the sleeve 21. The inner wall of the threaded cavity 212 is a threaded structure. The threaded boss 114 extends into the threaded cavity 212 and is threadedly connected to the sleeve 21. By aligning the threaded boss 114 with the threaded cavity 212 and tightening the sleeve 21, the sleeve 21 can be installed on the threaded boss 114, thereby achieving the purpose of installing the sleeve 21 on the gripping sleeve 1.

[0036] Specifically, a plurality of hanging plates 221 are integrally formed on the front end surface of the rotating seat 22. The hanging plates 221 are hook-shaped as a whole. The front ends of the hanging plates 221 extend into the through hole 211 and are hung at the edge of the opening of the through hole 211. A threaded hole 222 is provided at the middle position of the rotating seat 22, so that the rotating seat 22 is restricted to the tail end of the sleeve column 21 under the action of the hanging plates 221, and the rotating seat 22 can rotate at the tail end of the sleeve column 21.

[0037] Furthermore, the gripping and cutting structure 3 includes a straight rod 31 that extends into the gripping sleeve 1 and passes through the rotating structure 2, a plurality of clamping rods 32 mounted at the head end of the straight rod 31, and a cover 33 mounted between the head ends of the plurality of clamping rods 32. The head end of the straight rod 31 is integrally formed with an end post 311. The head end edge of the outer surface of the end post 311 is provided with a plurality of embedded grooves 3111. The tail ends of the clamping rods 32 are fixed in the embedded grooves 3111, so that the plurality of clamping rods 32 are fixed to the end post 311. The outer surface of the end post 311 is also integrally formed with a plurality of protrusions 3112. The inner wall of the sleeve 11 is provided with a plurality of guide grooves 1111. The protrusions 3112 extend into the guide grooves 1111 and are slidably connected to the sleeve 11, so that the end post 311 is restrained within the interior of the sleeve 11 by the action of the protrusions 3112. An external thread 312 is integrally formed on the outer surface of the tail of the straight rod 31. The tail of the straight rod 31 passes through the threaded hole 222 and is threadedly connected to the rotating seat 22. When the surgeon's hand holding the movable sleeve 12 overlaps the anti-slip protrusion 116 and the movable sleeve 12, the sleeve 11 and the movable sleeve 12 form an integral structure. At this time, the surgeon's other hand directly rotates the rotating seat 22 to make the rotating seat 22 drive the straight rod 31 to move along the sleeve 11 under the action of the threaded hole 222, so that the straight rod 31 drives the clamping rod 32 to move through the end column 311. When the end column 311 moves toward the tail end of the gripping sleeve 1, the head end of the clamping rod 32 will shrink toward the middle of the port 112 under the abutment of the trumpet-shaped port 112. When the end column 311 moves toward the head end of the gripping sleeve 1, the head end of the clamping rod 32 gradually extends from the port 112.

[0038] In addition, a limiting plate 313 is fixed to the tail end of the straight rod 31 to prevent the straight rod 31 from being separated from the rotating base 22 when the rotating base 22 is rotated.

[0039] It is worth noting that the clamping rod 32 is a bent rod-shaped structure. The clamping rod 32 is elastic, so that when the head end of the clamping rod 32 gradually extends from the port 112, the head end of the clamping rod 32 is in an outwardly open state. The head end of the clamping rod 32 is integrally formed with a cutting head 321. When the clamping rod 32 is pulled and the head end gradually shrinks, the head ends of the multiple clamping rods 32 can wrap around the tumor, causing the cutting head 321 at the end of the clamping rod 32 to gradually shrink and contact the root edge of the tumor. At this time, by rotating the grasping and cutting structure 3, the cutting head 321 can gradually cut the root edge of the tumor, achieving the effects of fast cutting, complete cutting surface, and clear cutting edge.

[0040] It is worth noting that the cover 33 is made of rubber material, and a number of bosses 331 are integrally formed on the outer surface of the cover 33 around the circumference. The number of the bosses 331 is equal to the number of the clamping rods 32 and the positions correspond one to one. A through groove 322 is provided on the outer surface of the head end of the clamping rod 32. The bosses 331 pass through the through groove 322 and are integrally formed with a hanging block 332. The size of the hanging block 332 is larger than the size of the through groove 322, so that the edge of the cover 33 can be fixed to the head end of the clamping rod 32 under the action of the hanging block 332, so that the head ends of multiple clamping rods 32 can drive the cover 33 to shrink and expand together when performing contraction and expansion movements, so that the cover 33 can connect the tumor cover inside for tumor cutting.

[0041] The working principle of the breast tumor cutter of the present invention is as follows:

[0042] After peeling off the skin flap and finding the tumor, the surgeon uses one hand to hold between the movable sleeve 12 and the anti-slip protrusion 116 and directly rotates the rotating seat 22 with the other hand, so that the rotating seat 22 can drive the straight rod 31 to move along the sleeve 11 under the action of the threaded hole 222, so that the straight rod 31 drives the clamping rod 32 to move toward the head end of the gripping sleeve 1 through the end column 311, and then as the clamping rod 32 moves toward the head end of the gripping sleeve 1, the head end of the clamping rod 32 gradually unfolds, so that the cover 33 can be opened under the action of the clamping rod 32, and finally, after covering the expanded cover 33 on the tumor, the surgeon rotates the rotating seat 22 in the opposite direction to make the head end of the clamping rod 32 move The movable cover 33 gradually shrinks so that the cover 33 can wrap the tumor. At this time, the cutting head 321 on the clamping rod 32 extends into the root edge of the tumor. The surgeon can hold the movable cover 12 with one hand and use the other hand to move the lever 115 to move the sleeve 11, so that the sleeve 11 rotates in the movable cover 12, thereby causing the sleeve 11 to drive the grasping and cutting structure 3 to rotate together, so that the cutting head 321 can rotate and cut the tumor. The surgeon can gradually shrink the cutting head 321 and rotate the tumor by continuously rotating the seat 22 and the sleeve 11 respectively, thereby achieving the purpose of cutting off the tumor, and has the effects of fast cutting, complete cutting surface, and clear cutting edge.
