The specific embodiment
This utility model has disclosed a kind of arc Binding Instrument, is particularly useful for an esophagus high position, the operation of rectum low level.As depicted in figs. 1 and 2, comprise being hinged into scissors-like two handle holders 1,2 that the afterbody of described handle holder 1,2 is grip part 11,21, the front end of described handle holder 1,2 is provided with chuck component.
In this preferred embodiment, described chuck component comprises the holder 12,22 that is arranged on described handle holder 1,2 front ends, and is arranged on the nail bin that can slide relatively 3 in the holder 12,22.Described holder 12,22 is the semi arch of hollow, and described nail bin 3 also is the hollow bulb that the semicircle arcuation is arranged on described holder 12,22.The internal structure of described nail bin 3 and the automatic purse-string suture device of prior art are similar, it is provided with pushing slice of nail 5 and nail 6, the front end of described pushing slice of nail 4 and nail 6 butts, the rear end of described pushing slice of nail 4 drives (shown in Fig. 4) by the ejector pin seat of being located in the holder 12,22 13,23.
Described each nail bin 3 is the semicircular ring setting, connected a nail anvil 5 in its ring, described nail anvil 5 removably is formed by connecting by two semi-rings, after being combined into a complete nail anvil 5, this nail anvil 5 comprises the through hole 53 of a perforation, and tissue 7 can pass this through hole 53 and be coated on nail anvil 5 end faces.In conjunction with Fig. 2 and shown in Figure 3, the outer circumference face of described nail anvil 5 is provided with nail forming tank 51, and described pushing slice of nail 4 can make nail took shape on the tissue 7 cooperating outside the nail 6 release nail bins 3 and with nail forming tank 51.Described holder 12,22 is provided with locating slot 14,24, and described nail anvil 5 is provided with the locating piece 52 that connects with described locating slot 14,24.Described two nail anvil semi-rings connect by the draw-in groove tight fit, perhaps pass through magnetic attracting.In this preferred embodiment, the radian of described holder 12,22, nail bin 3, pushing slice of nail 4, nail anvil 5 is identical.
Simply introduce work process of the present utility model below.
As shown in Figure 4, before operation, earlier two nail anvil semi-rings are compacted into a complete nail anvil 5 by draw-in groove, the inside of described nail anvil 5 is a through hole 53, and described nail forming tank 51 is positioned on the periphery of described nail anvil 5.Then one section tissue to be sewed up 7 is passed described through hole 5 and envelopes described nail anvil 5, and the tissue 7 that another section is to be sewed up is placed in this section tissue.
Then, handle holder 1,2 is opened, and holder 12,22 is clipped in the outside of described tissue 7.Then slowly to grip part 11,21 application of forces of handle holder 1,2, locating piece 52 on the nail anvil 5 can enter into the locating slot 14,24 on the described holder 12,22 at this moment, described like this holder 12,22 and nail anvil 5 location, the nail bin 3 that promptly is positioned at described holder 12,22 is also located with described nail anvil 5, that is the nail hole 31 of putting of described nail bin 3 is aimed at the nail forming tank 51 of described nail anvil.
Continue to push grip part 11,21, nail bin 3 can abut against on the described tissue 7.Because nail anvil 5 is inflexible, so nail bin 3 can be to described holder 12,22 slides within, and relative, described pushing slice of nail 4 can be pushed out of nail 6 outside the described nail bin 3, and cooperates with nail forming tank 51 and to make nail took shape on the tissue 7.
Like this, all ordered behind tissue, promptly finished the stitching of tubular type tissue when all nails 6.Withdraw from handle holder 1,2, then nail anvil 5 is taken apart and taken off from the tissue of sewing up.
Because this utility model does not need the necessary outstanding relatively nail anvil of traditional tubular type binding instrument, therefore Binding Instrument of the present utility model can be operated in the less zone of operative space, therefore goes for an esophagus high position, the operation of rectum low level.
This utility model still has multiple concrete embodiment.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of this utility model.
