Preferably, the housing middle-end of described nail barrel offers four symmetrical openings, is equipped with reinforcement between adjacent apertures.
Preferably, in the housing cross section of described nail barrel, the central angle of described opening is greater than the central angle of reinforcement.
Preferably, the shape of described pushing slice of nail and described nail barrel match, and the second cavity is offered in described pushing slice of nail middle-end inside, and described the second cavity is aimed at the first cavity of described nail barrel.
Preferably, the proximal extension of described only tube, to the near-end of housing, also extends to the near-end of the described only described pin anvil shaft that tube coordinates and stops the near-end of tube and cooperatively interact.
Preferably, in the through hole of described only tube, be provided with at least one gathering sill, at least one guiding rib is correspondingly set on described pin anvil shaft, described guiding rib can slide in described gathering sill.
Advantage of the present invention is:
1. by offer four symmetrical openings in nail barrel middle-end, in being used, operation can provide large form, and the only reduction setting of tube and reinforcement, and the relative set of pushing slice of nail, makes to be convenient in operation drawing in and hold more and cutting and organizing of tissue;
2. only tube proximal extension arranges, and has made up nail barrel and reinforcement and has reduced the deficiency that the axial and circumferential intensity of bringing is set; Pin anvil shaft near-end also extends setting, has increased pin anvil shaft and has stopped coordinating of tube.

Wherein: 1, nail barrel; 2, pin anvil ring; 21, pin anvil shaft; 3, opening; 31, distal edge; 4, reinforcement; 5, the first cavity; 11, housing; 12, near-end; 13, stop tube; 14, pushing slice of nail; 15, the second cavity.
Detailed description of the invention
Embodiment mono-: shown in Figure 1, the invention provides a kind of nail-head component of circular-pipe anastomat, at least comprise pushing slice of nail 14 and the nail anvil shown in the nail barrel 1 shown in Fig. 2, Fig. 3.Described nail anvil comprises the pin anvil ring 2 and the pin anvil shaft 21 that are mutually permanently connected.
Specifically shown in Figure 2, described nail barrel 1 comprises a housing 11, the near-end 12 of described housing 11 is for being connected with the body of circular-pipe anastomat, in described housing 11, be provided with only tube 13 and pushing slice of nail 14, only tube 13 comprises a through hole, and this through hole is for sliding through the pin anvil shaft 21 of nail anvil, preferred embodiment is, only in the through hole of tube 13, be provided with two gathering sills, two guiding ribs are correspondingly set on described pin anvil shaft 21, described guiding rib can slide in described gathering sill.
In this preferred embodiment, be provided with four symmetrical openings 3 at the side opening of described nail barrel 1, such four sides opening arranges can provide large form to medical personnel in operation, and 3 of adjacent apertures are equipped with reinforcement 4.Described opening 3 with connect for the first cavity 5 that holds tissue to be cut, the distal edge 31 that the far-end of described only tube 13 is less than described opening 3 to the distance of the near-end 12 of housing 11 arrives the distance of the near-end 12 of housing 11, have at least the first cavity 5 of part to reveal from described opening 3, make to be convenient in operation drawing in and hold more and cutting and organizing of tissue.And in housing 11 cross sections of described nail barrel 1, the central angle of described opening 3 is greater than the central angle of reinforcement 4.Large opening setting like this, makes doctor in the time of operation, have splendid observation visual angle.
Further, the housing 11 of one end of described reinforcement 4 and nail barrel 1 is wholely set, and the length of the other end equals the described only length of tube 13.Shown in Fig. 3, the shape of described pushing slice of nail 14 and described nail barrel 1 match, and the second cavity 15 is offered in described pushing slice of nail 14 middle-end inside, and described the second cavity 15 is aimed at the first cavity 5 of described nail barrel 1.Pushing slice of nail 14 is similar with arranging of nail barrel 1, is in order to bring larger receiving space equally, holds more tissue to be cut.
In order to make up the deficiency of axial and circumferential intensity of the apparatus that only reduction of tube 13 and reinforcement 4 brings, only tube near-end has carried out extending and has arranged, and also corresponding proximal extension of pin anvil shaft, increases pin anvil shaft and stop coordinating of tube simultaneously.Be specially: the proximal extension of described only tube, to the near-end of housing, also extends to and the near-end that stops tube with the near-end of the described only described pin anvil shaft that tube coordinates.
Far-end in the present invention and near-end are the residing positions of apparatus while performing the operation with doctor, and one end nearer apart from doctor is near-end, and one end far away apart from doctor is far-end.
The present invention still has numerous embodiments, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, within all dropping on the scope of protection of present invention.
