Detailed Description

In order to make the technical problem, technical solution and beneficial effects to be solved by the present invention more clearly understood, the following description is made in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example one

As shown in fig. 1-4, an integrated cutting device for splitting tissue of an internal gingival contact surface comprises a surgical scissors 1, wherein the surgical scissors 1 comprises a first scissor 2 and a second scissor 3, the middle parts of the first scissor 2 and the second scissor 3 are hinged through an intermediate shaft 4, an adjusting shaft 6 penetrates through a knife body 5 of the surgical scissors 1, the adjusting shaft 6 and the intermediate shaft 4 are the same shaft, a section of the adjusting shaft 6 penetrating through the knife body 5 is a polished rod 7, a section of the adjusting shaft 6 extending to the outside of the knife body 5 is a threaded rod 8, and one end of the polished rod 7 is positioned on the knife body 5 through a tapered end 9.

The device further comprises a baffle 10, one end of the baffle 10 is sleeved on the adjusting shaft 6, the other end of the baffle 10 is free, a return spring 11 is compressed between the baffle 10 and the cutter body 5, the outer side of the baffle 10 is locked on the threaded rod 8 through a nut 12, and the position of the baffle 10 on the threaded rod 8 is adjusted through the screwing position of the adjusting nut 12, so that the distance between the baffle 10 and the cutter body 5 is adjusted.

The baffle 10 is a flat plate, the common baffle 10 structure on the flat plate combines the flat plate structure with scissors, the processing difficulty is small, and the matching degree is good.

When the novel scissors are used, the position of the nut 12 on the threaded rod 8 is adjusted according to the thickness of the cut gingiva of a patient, the distance between the free end of the baffle 10 and the cutter head of the scissors is further adjusted, the cutter head of the scissors and the free end of the baffle 10 extend into the oral cavity, the baffle 10 abuts against the outer side face of the gingiva, a doctor can hold the scissors by hand to shear redundant tissues on the inner side face of the gingiva, the phenomenon that the doctor holds the baffle 10 by hand all the time is avoided, and the labor intensity of the doctor is relieved. The adjusting shaft 6 and the intermediate shaft 4 of the utility model are a shaft, which does not affect the use of the scissors completely.

The nut 12 is screwed inwards, and the distance between the baffle 10 and the scissor head is reduced; the nut 12 is screwed outwards, the distance between the baffle 10 and the scissors head is increased, and the baffle 10 and the scissors head are always stably supported and cannot shake randomly under the action of the return spring 11 because the return spring 11 is in a compression state.

When the baffle 10 needs to be replaced for cleaning, the nut 12 is unscrewed, and replacement can be achieved, which is very convenient.

Example two

As shown in fig. 5 to 6, the present embodiment differs from the first embodiment in the hinge position of the blocking plate 10, in the present embodiment, the first scissors 2 serves as a driving scissors, the second scissors 3 serves as a driven scissors, the blocking plate 10 is hinged to the second scissors 3 through the adjusting shaft 6, and the adjusting shaft 6 is disposed between the holding end of the second scissors 3 and the intermediate shaft 4. The connection mode can ensure that the hinged shaft of the baffle 10 does not interfere with the inner wall of the oral cavity, and the operation is more convenient.

EXAMPLE III

As shown in fig. 7, the difference between this embodiment and the first embodiment is the shape of the baffle 10, the end of the baffle 10 hinged to the adjusting shaft 6 is a flat plate, the end of the baffle 10 facing the cutting head of the surgical scissors 1 is an arc-shaped plate, the arc-shaped plate is bent inward toward the cutting head of the surgical scissors 1, and the distance between the baffle 10 and the cutting head of the scissors is small, so that the clamping degree is better.

The foregoing is considered as illustrative and exemplary embodiments of the invention, and is not to be construed as limiting the invention, which is intended to be broadly construed as the invention in any manner, including any variations, equivalents and modifications within the spirit and scope of the invention.
