Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to 2, it is a schematic structural diagram of a soft tissue cutting knife for dentistry provided by the present invention. The utility model provides a soft tissue cutting ring for dentistry, includes cutting ring handle pole 10 and locates cutting head 20 of cutting ring handle pole 10 one end, cutting head 20 is equipped with the holding tank 21 that is used for holding the soft tissue, 20 lateral walls of cutting head be equipped with holding tank 21 communicates with each other and two corresponding through-holes 22, cutting head 20 keeps away from cutting ring handle pole 10 one end is equipped with ring cutting edge 23, cutting ring handle pole 10 is from keeping away from cutting head 20 one end is used for being connected with the driving piece. The use process comprises the following steps: in the operation of filling is planted in the oral cavity, fix annular cutter handle pole 10 one end on the driving piece, with tool bit 20 put in advance in patient's oral cavity department, through driving piece downstream and make annular cutter handle pole 10 rotate, the annular cutting edge 23 on the tool bit 20 on the annular cutter handle pole 10 rotates and cuts open the gum soft tissue, then takes out the soft tissue ring cutter for the dentistry to the gum soft tissue that will inlay the cutting that cuts in the holding tank 21 of tool bit 20 takes out together, can expose the operation field of vision. When cleaning disinfection dentistry is with soft tissue cutting ring after the operation, accessible tweezers or other article pass through-hole 22 in holding tank 21 to wear into the soft tissue that inlays in holding tank 21 of tool bit 20, the rethread article removes to cutting edge 23 direction, can take out the soft tissue that inlays in holding tank 21 of tool bit 20, and is very convenient and fast, improves work efficiency.

The ring cutter handle rod 10 is provided with an annular positioning groove 11 and a circumferential positioning notch 12 at one end far away from the cutter head 20. In order to facilitate installation, connection and fixation, the annular positioning groove 11 is arranged for preventing axial separation, and the circumferential positioning notch 12 is arranged for ensuring circumferential fixing stability, avoiding circumferential rotation and further improving the stability of the soft tissue ring-cutting knife for dentistry when the soft tissue ring-cutting knife is used for ring-cutting soft tissue.

The outer diameter of the cutter head 20 is greater than the outer diameter of the ring cutter shank 10. The volume of the accommodating groove 21 is larger, more soft tissues can be accommodated, the outer diameter of the ring cutter handle rod 10 is smaller, the ring cutter handle rod 10 can be driven to rotate only by the driving piece with smaller driving force, and the cutter head 20 drives the ring cutting edge 23 to ring cut the soft tissues.

The annular cutting edge 23 and the cutter head 20 are integrally formed. The ring-cutting edge 23 has stronger structural strength and is more stable when used for ring-cutting soft tissues.

The ring cutter shank 10, the cutter head 20 and the ring cutter edge 23 are made of stainless steel.

The cutter head 20 is detachably connected with the ring cutter handle rod 10. The cutting tool is characterized in that a groove (not marked in the drawing) matched with the ring cutting tool handle rod 10 and an internal thread (not marked in the drawing) positioned on the inner side wall of the groove (not marked in the drawing) are arranged at one end, connected with the ring cutting tool handle rod 10, of the cutting tool head 20, and an external thread 13 matched with the internal thread (not marked in the drawing) is arranged on the outer side wall of one end, connected with the cutting tool head 20, of the ring cutting tool handle rod 10. When the tool bits 20 with different diameters are needed, the tool bits 20 which do not conform to the patient can be detached from the ring-cutting knife handle 10 through rotation, and the tool bits 20 which conform to the patient are installed and fixed on the ring-cutting knife handle 10 through rotation, so that convenience is greatly improved.

Compared with the prior art, the utility model provides a soft tissue cutting ring for dentistry passes through tweezers or other article through-hole 22 in holding tank 21 to wear into the soft tissue that inlays in holding tank 21 of tool bit 20, the rethread article removes to cutting edge 23 direction, can take out the soft tissue that inlays in holding tank 21 of tool bit 20, and very convenient and fast improves work efficiency.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
