Part；Upper clamping semi-ring, lower one end for clamping semi-ring are hinged, and the other end can engage, and the end face of the two, which is equipped with, can make cutter assembly
Around the cunning cutter groove slided；Barrel mast shape knife anvil ring, which can be clamped to, to be clamped between semi-ring, lower clamping semi-ring.
Above-mentioned cutter assembly has following two design scheme:
It 1, include truncation cutter, knife groove, elastic slice, hand handle on knife assembly；Knife groove and the sliding cutter groove cooperate, and make bullet
Piece is attached to the outside of sliding cutter groove.
It 2, include cutter shaft, curved knife, knife cover, knife rest, safety plug on cutter assembly；Knife rest is equipped with hand handle, cutter shaft hole, phase
Intercommunicated knife cover safety vent and knife cover open hole, elastic slice, the knife rest T shape pin with sliding cutter groove cooperation；Cutter shaft is solid by cutter shaft hole
It is scheduled on knife rest；Curved knife and cutter shaft rotatable engagement；Curved knife periphery is equipped with the slightly larger knife cover of outer diameter, and knife, which is provide with, sets portable pillar；
Portable pillar can open activity between hole in knife cover safety vent, knife cover, and thus knife cover is overlapped or is staggered with curved knife；Safety plug is inserted
It is being set in the upper breaking pin hole for clamping semi-ring, cutter assembly is being fixed, and be pressed in elastic slice on the outer wall of sliding cutter groove.Institute
It can be round or non-circular for stating curved knife shape.
The design scheme of another cylindrical surface annular cutter tool: including upper clamping semi-ring；Lower clamping semi-ring, column nail
Anvil, upper half dise knife, lower half dise knife；Upper clamping semi-ring and lower clamping semi-ring one end are hinged, and the other end is engageable；Upper half dise knife is under
Half dise knife is hinged and is fixed within clamping semi-ring and lower clamping semi-ring；Column nail anvil can be by upper half dise knife and lower half circle cutter holder
Tightly.
Compared with prior art, the beneficial effects of the present invention are: when operation, can accomplish cylindrical surface shearing it is primary complete
At；Notch is uniformly neat, and procedure efficiency is high, and beautiful mechanism is simple after wound healing, easy to operate, does not open after shearing in framework
In the case where doctor also can real-time judge shear effect.

Specific embodiment
For those skilled in the art, revealed structure and principle various other phases can be obtained according to the present invention
The change and deformation answered, and all these change and deformation belongs to protection category of the invention.
A kind of cylindrical surface annular cutter tool, including upper clamping semi-ring 1, lower clamping semi-ring 2, barrel mast shape knife anvil ring (4,
18), cutter assembly (3,20)；Upper clamping semi-ring (1,15) and lower one end for clamping semi-ring (2,16) are hinged, and the other end can engage,
The end face of the two, which is equipped with, can make cutter assembly around the cunning cutter groove (102,202,152) slided；Barrel mast shape knife anvil ring (4,18)
It can be clamped to and clamp between semi-ring (1,15), lower clamping semi-ring (2,16).
Above-mentioned cutter assembly has following two design scheme:
It 1, as shown in Figures 1 to 3, include truncation cutter, knife groove 301, elastic slice 302, hand handle 303 on cutter assembly 3；Knife is recessed
Slot 301 and the upper downslide cutter groove (102,202) cooperate, and elastic slice 302 is made to be attached to the outsides of sliding cutter groove (102).
When the cutter operates, the prepuce tissues cut are inserted in column nail anvil 4, are clamped semi-ring (1,2) up and down and are clamped.Knife
Mouthfuls 304 are pressed in the tissue cut by the pressure of spring leaf 302, when holding hand handle 303 along cunning cutter groove along barrel mast shape
When nail anvil 4 slides, the edge of a knife 304 can cut open tissue, to achieve the purpose that annular cutting tissue.5 function of flexible glue edge bearing is protection knife
Mouthful and ensure that tissue is completely severed.
2, as shown in Fig. 6~10, include cutter shaft 201 on cutter assembly 20, curved knife 202, knife cover 203, knife rest 204, protect
Dangerous pin 205；Knife rest 204 is equipped with hand handle 2041, cutter shaft hole 2042, interconnected knife cover safety vent 2043 and knife cover and opens hole
2044, elastic slice 2045, the knife rest T shape pin 2046 cooperated with sliding cutter groove 152；Cutter shaft 201 is fixed on knife rest by cutter shaft hole 2042
On 204；Curved knife 202 and 201 rotatable engagement of cutter shaft；202 periphery of curved knife is equipped with the slightly larger knife cover 203 of outer diameter, and knife cover 203 is set
Set portable pillar 2031；Portable pillar 2031 can open activity between hole 2044 in knife cover safety vent 2043, knife cover, thus by knife cover
203 are overlapped or are staggered with curved knife 202；Safety plug 205 is inserted in the breaking pin hole 151 for being set to and clamping semi-ring 15, will be cut
Knife assembly 20 is fixed, and is pressed in elastic slice 2045 on the outer wall of sliding cutter groove 152.
Cutter makes portable pillar 2031 slide to knife cover from knife cover safety vent 2043 and opens hole in use, stir portable pillar 2031
2044, knife cover 203 is staggered with curved knife 202 at this time, and the edge of a knife 2021 of curved knife 202 exposes, in case cutting.
Safety plug 205 is extracted, entire knife cuts component 20 and acts on lower swing to barrel mast shape knife anvil ring in the elastic force of elastic slice 2045
On 18, and 202 pairs of curved knife cutting tissues generate certain pressure；It holds 2041 slid clockwise knife of hand handle and cuts component 20, arc
Shape knife 202 does revolution motion along barrel mast shape knife anvil ring 18, while curved knife 202 is also done rotation movement along cutter shaft 201, the edge of a knife
2021 along a group selvedge to turn side sliding, a circle or a few tissue cutting is separated, to reach ring cutting purpose.
Curved knife 202 may be designed to full circle rotation shape or non-full circle maintains static shape.As shown in Figure 9 and Figure 10.Work as arc
When knife 202 is designed to non-full circle, curved knife 202 and cutter shaft 201 are fixed design, nonrotating state, and the edge of a knife is towards barrel mast shape knife
Anvil ring 18；Curved knife 202 does revolution motion along barrel mast shape knife anvil ring 18 when cutting, but curved knife 202 is not done rotation movement, knife
Mouth equally reaches ring cutting purpose along tissue stroke.
The design scheme of another cylindrical surface annular cutter tool: including upper clamping semi-ring 7；Lower clamping semi-ring 8, column nail
Anvil 10, upper half dise knife 13, lower half dise knife 14；Upper clamping semi-ring 7 and 8 one end of lower clamping semi-ring are hinged, and the other end is engageable；Upper half
Dise knife 13 and lower half dise knife 14 are hinged and are fixed on and clamp within semi-ring 7 and lower clamping semi-ring 8；Column nail anvil 10 can be by upper half
Dise knife 13 and lower half dise knife 14 clamp.
Upper half dise knife 13 and lower half dise knife 14 pass through the link of pin B 12, form a handcuffss shape pincer cutting mechanism,
It is inserted in column nail anvil 10 by cutting tissue, after upper half dise knife 13 and lower half dise knife 14 clamp cutting tissue by external force, on
The semicircle edge of a knife 1301 and the lower half circle edge of a knife 1401 form a circular complete annular edge of a knife；Tissue annular is cut.Flexible glue knife
Padding 5 functions is the protection edge of a knife and ensures that tissue is completely severed.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
