Still further alternatively, as shown in fig. 2, in the present embodiment, the medicine-carrying groove 200 includes a plurality of medicine-carrying sub-grooves 210, and the plurality of medicine-carrying sub-grooves 210 are disposed at intervals along the circumferential direction of the cutter body 100. The medicine carrying groove 200 may be a regular groove such as a square groove, a round groove, a kidney-shaped groove, or a special-shaped groove such as a flower-shaped groove and a corrugated-shaped groove. The arrangement of the medicine carrying slots 210 can ensure the structural strength of the cutter body 100, and avoid the rapid decrease of the structural strength of the cutter body 100 at the slotting position caused by continuous slotting, thereby avoiding the occurrence of the fracture phenomenon of the cutter body 100.
Further, since the kinds of medicines to be used at the incision may be various, a plurality of medicine carrying grooves 200 may be provided on the outer wall surface of the cutter body 100 along the cutting direction according to the requirements, each medicine carrying groove 200 includes a plurality of medicine carrying sub-grooves 210, and along the direction parallel to the axial direction, two adjacent medicine carrying sub-grooves 210 may be arranged in a staggered manner or may be arranged in a collinear manner. The drugs carried in the different drug carrier channels 210 may be the same or different. The drug loading depth of each drug loading slot 210 may be the same or different. The capacity of each drug carrier slot 210 may be the same or different. In this embodiment, the number of medicine carrying slots 200 is selected according to the kinds of medicines to be carried, and each medicine carrying slot 200 includes a plurality of medicine carrying sub-slots 210 for carrying the same medicine.
Further, the medicine carrying slot 210 includes three inner wall surfaces, which are two opposite side wall surfaces and a slot bottom surface, so as to prevent the medicine in the medicine carrying slot 210 from falling to the non-incision position, the inner wall surface of the medicine carrying slot 210 is provided with an adsorption structure for adsorbing the medicine, thereby achieving the purpose of preventing the medicine from falling from the medicine carrying slot 210. Alternatively, the adsorption structure may be a solid structure such as an adsorption film coated or provided on the inner wall surface, and of course, the adsorption structure may be an adsorption roughened surface, which is a roughened surface having an adsorption effect formed by increasing the surface roughness of the inner wall surface, in addition to the solid structure. Alternatively, the medicine may be mixed with the polymer and then sprayed into the medicine carrying groove, and the viscosity of the medicine may be increased by the polymer, so that the medicine may be stably placed in the medicine carrying groove 210, and the purpose of preventing the medicine from falling from the medicine carrying groove 210 may be achieved.
Alternatively, the depths of the medicine-carrying grooves 210 may be the same or different, and in this embodiment, the groove bottom is configured as an inclined surface, so that the depths of the medicine-carrying grooves 210 are different, so that as much medicine in the medicine-carrying grooves 210 can be attached to the cut portions as possible. Specifically, in the present embodiment, the groove bottom surface is inclined in a direction away from the axial direction in the cutting direction, so that the medicine carrying depth of the medicine carrying groove 210 is gradually reduced, and the tissue 300 entering the medicine carrying at the incision can push the medicine upward and rearward during the contact with the medicine during the medicine applying process, so that as much medicine as possible sticks to the tissue 300 at the incision.
