Specific embodiment

For those skilled in the art, it can be obtained according to the revealed structure of the utility model and principle other each Kind is corresponding to be changed and deforms, and all these change and deform the protection category for belonging to the utility model.

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.

Another design scheme of cylindrical surface annular cutter tool: as shown in Figures 4 and 5, including upper clamping semi-ring 7；Lower folder Tight 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, separately One 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 Shape nail anvil 10 can be clamped by upper half dise knife 13 and lower half dise knife 14.

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.

Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to In the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
