The specific embodiment
The rotary cutter of a kind of binding device for surgery shown in Fig. 1～11, it includes nail bin 1, pushing slice of nail 2, annular cutting knife 3, ejector pin post 4, nail tube 5, also include rotating member, its special feature is: described rotating member is rotation set 7 and helical orbit device, on rotation set 7, be provided with helicla flute, in nail tube 5, only rise and be provided with the helical orbit device that matches with helicla flute on the rotation set 7 on the pipe 6, described nail bin 1, pushing slice of nail 2, annular cutting knife 3, ejector pin post 4, nail tube 5, annular cutting knife 3 feed arrangements that rotation set 7 and helical orbit device constitute are swivel feeding device, nail tube 5 is that an inner chamber is step-like round tubular body, be provided with the pipe 6 that only rises in it, between only rise pipe 6 and nail tube 5 inwalls, be provided with and follow closely the step-like round tubular body pushing slice of nail 2 that 5 inner wall shape is complementary, front end at nail tube 5 and pushing slice of nail 2 is the cavity that is complementary with annular cutting knife 3, annular cutting knife 3 is enclosed within on the pipe 6 that only rises and is arranged in this cavity, being provided with the helical orbit device on the pipe 6 that only rises is connected with rotation set 7 spirals, nail tube 5 is connected with annular nail bin 1 respectively with the nose circle circumferential edges of pushing slice of nail 2 and touches, and annular cutting knife 3 is managed 6 and is connected with only rising by rotation set 7 and pushing slice of nail 2.Furthermore, rotation set 7 is located at the inner bottom surface of annular cutting knife 3, and the bottom that pushing slice of nail 2 front end cavity inner bottom parts are provided with hook and annular cutting knife 3 articulates.Perhaps, described rotation set 7 can also be located at the outer bottom of annular cutting knife 3, and the bottom that pushing slice of nail 2 front end cavity inner bottom parts are provided with hook and rotation set 7 articulates.Again specifically, described helical orbit device is the helical orbit that is directly arranged on the pipe 6 that only rises, and rotation set 7 is connected with pipe 6 spirals that only rise.Realize that described helical orbit device also is fixing screw-casing 7, it is fixed on pipe 6 peripheries that only rise, and outer wall is provided with helical orbit, is provided with spacing clamp nut 10 above the threaded insert 8 only rising to manage on 6.Described pushing slice of nail 2 is the segmentation setting with ejector pin post 4, and 4 on pushing slice of nail 2 and ejector pin post are smooth touching.
" embodiment one "
As shown in Figure 1 and Figure 2, pushing slice of nail 2 is an one with ejector pin post 4, and rotation set 7 is located at the inner bottom surface of annular cutting knife 3, and the bottom that pushing slice of nail 2 front end cavity inner bottom parts are provided with hook 12 and annular cutting knife 3 articulates.When pushing slice of nail 2 is subjected to forward a displacement, will drive rotation set 7 and annular cutting knife 3 travels forward, simultaneously, the matching effect of helical guideway 9 of the helical guideway groove 11 of rotation set 7 and the pipe 6 that only rises of nail tube forces rotation set 7 generations to rotatablely move.Because of rotation set 7 and annular cutting knife 3 riveted and fixed, so annular cutting knife 3 is with rotation set 7 rotations.After bookbinding finished, annular cutting knife 3 and rotation set 7 were withdrawn under the effect of the barb 12 of pushing slice of nail in the nail tube.
" embodiment two "
As Fig. 5, Fig. 7, shown in Figure 8, pushing slice of nail 2 is an one with ejector pin post 4, and rotation set 7 is located at the outer bottom of annular cutting knife 3, and the bottom that pushing slice of nail 2 front end cavity inner bottom parts are provided with hook 12 and rotation set 7 articulates.When pushing slice of nail 2 is subjected to forward a displacement, will drive rotation set 7 and annular cutting knife 3 travels forward, simultaneously, the matching effect of helical guideway 9 of the helical guideway groove 11 of rotation set and the pipe 6 that only rises of nail tube forces rotation set 7 generations to rotatablely move.Because of rotation set 7 and annular cutting knife 3 riveted and fixed, so annular cutting knife 3 is with rotation set 7 rotations.After bookbinding finished, annular cutting knife 3 and rotation set 7 were withdrawn under the effect of the barb 12 of pushing slice of nail in the nail tube.
" embodiment three "
Shown in Fig. 6～8, pushing slice of nail 2 is an one with ejector pin post 4, and rotation set 7 is located at the inner bottom surface of annular cutting knife, and fixedly screw-casing 13 is fixed on pipe 6 peripheries that only rise, and outer wall is provided with helical guideway 9, is provided with spacing clamp nut 10 above the threaded insert 8 on the pipe 6 that only rises.The bottom that pushing slice of nail 2 front end cavity inner bottom parts are provided with hook 12 and rotation set 7 articulates.When pushing slice of nail 2 is subjected to forward a displacement, will drive rotation set 7 and annular cutting knife 3 travels forward, simultaneously, the helical guideway groove 11 of rotation set and fixedly helical guideway 9 effect of matching of screw-casing force rotation set 7 to produce and rotatablely move.Because of rotation set 7 and annular cutting knife 3 riveted and fixed, so annular cutting knife is with rotation set 7 rotations.After bookbinding finished, annular cutting knife 3 and rotation set 7 were withdrawn under the effect of the barb 12 of pushing slice of nail in the nail tube.
" embodiment four "
Shown in Fig. 7～11, described pushing slice of nail 2 is the segmentation setting with ejector pin post 4, and 4 on pushing slice of nail 2 and ejector pin post are smooth touching.When ejector pin post 4 is subjected to forward percussion displacement, because the helical guideway of the pipe that only rises of nail tube 5 forces ejector pin post 4 that the displacement forward of a rotation takes place, because ejector pin post 4 is fixedlyed connected with annular cutting knife 3, so annular cutting knife 3 rotates displacement forward too, simultaneously, because pushing slice of nail 2 is not connected with ejector pin post 4, so pushing slice of nail 2 is not influenced by rotation, only can produce a percussion displacement forward, the function of cutter rotation cutting when so just reaching the bookbinding percussion, it is safer and convenient that cut-out is organized.
By above-mentioned literal and in conjunction with the accompanying drawings as can be seen, its advantage is to realize the rotation cutting function, effectively reduces the resistance that cuts off tissue, reduces because of what cut-out caused and organizes tensile wound, and safety and reliability ground guarantees to cut off tissue, reduces the bookbinding power of performing the operation required.
