It is understood that the names of the first forceps body 100 and the second forceps body 200 are not limited to the arrangement position of the guiding structure 310, and similarly, the guiding structure may also be arranged on the head section of the first forceps body, and one end of the peeling wire is fixed on the end of the head section of the second forceps body, and the other end passes through the guiding structure and then is fixedly connected to the wire-retrieving structure.
The wire take-up structure 420 is a tape spring, which can realize automatic unfolding of the structure by utilizing elastic strain energy accumulated during folding without other power devices; after the clamp is unfolded, the locking force required by a large-scale expandable structure can be provided by the rigidity of the clamp, and two ends of a rotating shaft of the clamp are fixed on the clamp arm sections, so that a tape measure spring is fixed on the clamp arm sections, wherein the clamp arm sections can be on the first clamp body 100 or the second clamp body 200, only the routing of glass wires is different, and the principle is the same.
The locking structure 600 includes a locking rod 610 and a locking handle 620, which are engaged with each other, one end of the locking rod 610 is fixedly connected to the forceps arm section 400 of the first forceps body 100, and the other end of the locking rod passes through the forceps arm section 400 of the second forceps body 200. The locking handle 620 is disposed on the forceps arm section 400 of the second forceps body 200 and below the locking rod 610. The locking lever 610 is provided with a locking tooth 611 towards the locking handle 620, the locking handle 620 comprises a convex tooth 621 matched with the locking tooth 611 and a handle 622 driving the convex tooth 621 to be far away from the locking tooth 611, wherein the handle 622 is hinged with the forceps arm section 400. After the handle 622 is pressed downwards, the handle 622 drives the convex tooth 621 to be far away from the locking rod 610, the opening degrees of the first forceps body 100 and the second forceps body 200 are adjusted according to the size of the lipoma, then the handle 622 is loosened, the convex tooth 621 is clamped into the appropriate locking tooth 611, and the take-up device 420 locks the length of the stripping line. I.e. the stripper is adjusted to be optimal.
Referring to fig. 3, the stripping line 500 needs to be adjusted in length according to the size of the lipoma, and therefore, the stripping line is in a movable state, and in order to avoid the interference of the operation caused by the movement of the stripping line in the operation, a guide structure 310 is arranged on the head 300, the guide structure 310 can be a guide groove 312 arranged on the head section 300, the stripping line is limited in the guide groove 312, and the stripping line 500 is prevented from sliding in the operation to change the tightness. The guiding structure 310 can also be a guiding groove 312 formed on the head section 300 and a guiding ring 311 arranged on the guiding groove 312, so as to further guide and limit the stripping wire 500, thereby ensuring that the stripping wire cannot run.
According to the superficial lipoma stripper, the opening degrees of the first clamp body and the second clamp body are adjusted according to the size of lipoma, so that the size of a closed loop formed by a stripping line and the head section is adjusted. Therefore, the deep part of the lipoma is separated, the operation is finished under blind vision, the tumor does not need to be completely turned over, and the tissue damage is greatly reduced. Meanwhile, the length of the incision can be controlled to be the shortest, and the pain of a patient is reduced.
