 弯端型与直线型环切吻合器结构相似，对于直线型吻合器的吻合机构，因为其动作与直线型环切吻合器有些不同，具体地说，直线型吻合器的吻切机构包括抵钉座、钉仓和直线形切割刀以及推钉组件，所述的推钉组件包括可推动钉仓和切割刀向前行进的推钉板和与所述的推钉板一体形成的连接杆或连接筒，所述的连接杆或连接筒后端部可匹配地插入前推管前端部，且所述的连接杆或连接筒后端部外壁面上形成有环凹槽，贯穿前推管的销钉将前推管和连接杆或连接筒可传动连接，同时所述的连接杆或连接筒外侧壁与前管体间对应地设置有防止连接杆旋转的导向棱和导向槽结构。  The curved end of the linear type staplers cutting ring structurally similar to the stapling mechanism of the linear stapler, and the operation thereof as linear cutting staplers ring is somewhat different, in particular, linear stapling mechanism osculating comprising the anvil, the staple cartridge and rectilinear cutting blade and a push screw assembly, the connector assembly includes a push staple cartridge and cutting blade forward travel of the staple pushing plate and the staple pushing plate integrally formed may push rods or connection tube, said connecting rod or connecting the rear end portion of the barrel may be matingly inserted into the front push tube distal portion has a ring groove formed in the connecting rod and the connecting tube or the rear end portion of the outer wall surface, pushed through the front pin tubes of the front tube and the push rod or the connecting cylinder may be connected to the transmission connection, while provided between said connecting rod or cylinder connected to the outer tube side wall in correspondence with the front guide ribs prevent the connecting rod and the guide groove structure rotates. 即利用环凹槽和销钉实现传动，结合导向棱槽的导向即可实现前推管驱动推钉组件前后移动。 That is achieved using a drive ring groove and pin, in conjunction with the guide groove of the guide ribs to move back and forth before the implement to push the staple push-tube drive assembly.
 所述的直线型吻合器的抵钉座包括抵钉板和连接臂，所述的连接臂末端形成有与之垂直的传动臂，所述的传动臂末端形成有连接块，所述的前中心杆上形成有可将所述的连接块嵌含其内的螺旋形凹槽，即传动臂的贯穿形成在前管体和前推管上的通孔并将端部的连接块嵌入前中心杆杆体上的凹槽内。 Linear stapler  of the anvil plate and the staple connection comprises a contact arm, the connecting arm is formed perpendicular to the end of the transmission arm, the transmission arm end is formed with a connecting block, the the front center of the connecting rod is formed with a block may contain the insert within the spiral groove, i.e., through the drive arm is formed into the through-hole and the connection block on a front end portion of the tubular body and a front push tube a groove provided on the front center thereof club. 为提高连接块与凹槽的配合，可采用T形槽结构，能有效方式连接块脱槽影响传动。 To improve the fit of the connector block with the groove, T-shaped groove structure can be, connected effectively block off the groove affect the transmission.
 进一步地，为将直线型吻合器的抵钉座保持与前管体相对固定，利用保持环将连接臂和前管体包容在一起，所述的保持环为两个固定连接的半环形，其将连接臂和前管体相对限位在一起，同时，为引导抵钉座前后移动，在连接臂与前管体或者保持环间对应地设置有防止连接臂旋转的导向棱和导向槽结构。  Further, the anvil of the linear stapler is held stationary relative to the front tubular body by the retaining ring and the front arm is connected with the tubular body inclusive of the retaining ring is fixedly connected to two half- ring, which connecting arm and the tubular body opposite the front stop together, simultaneously, to guide the back and forth movement of the anvil, the connecting arm or the front tube holder provided corresponding inter-ring for preventing rotation of the connecting arm and the guide rib of the guide slot structure. 即，利用连接块在螺旋形凹槽内的滑动实现传动，并利用导向棱槽的导向即可实现将抵钉座前后驱动。 That is, the driving can be realized using the anvil longitudinal slider in the guide groove connection implemented helical gear, and by the guide rib grooves.
 而针对电动腔镜吻合器，因为其没有推管结构，只需中心杆的旋进即可实现全部动作，具体来说，电动腔镜吻合器的吻切机构包括直板型抵钉座1，钉仓2和上下两端分别于钉仓和抵钉座滑动连接的直切刀3，所述的抵钉座与前管体固定连接，所述的钉仓与前管体铰接，所述的直切刀后部与前中心杆可传动连接。  and for motorized endoscopic stapler, because it does not push the pipe structure, only the central rod screwed into the entire operation can be realized, particularly, the electric stapler of kiss-cutting endoscopic mechanism comprising a bar-type anvil 1, the staple cartridge 2, and upper and lower ends respectively of the staple cartridge and the anvil of a linear cutter sliding connection 3, the anvil is fixedly connected with the front tube, said cartridge front articulated tube, the He said rear portion of the front cutter straight center rod driving connection.
 其中，直切刀的前端下部形成有与设置在抵钉座上的T形滑槽对应的滑块，同时，直切刀的前端上部形成有与钉仓上的滑槽对应的导柱，当直切刀受驱动向前移动时，因为滑块被T形滑槽限位只能沿T形滑槽向前移动，导柱与滑槽的作用即可拉近钉仓与抵钉座的距离，随着直切刀行进切割组织，钉仓与抵钉座的靠近即可同步完成缝合。  wherein the lower distal end formed with a straight cutting blade disposed in the staple against the T-shaped seat corresponding to Huacao slider while the upper front end of the straight cutting blade corresponding to a run channel on the staple cartridge has turned column straight when the cutter is driven to move forward, because only the slider is moved forward along the T-shaped slide chute T limit, the effect of the guide post and the chute closer to the staple cartridge and the anvil the distance the cutter travels straight as cutting tissue, the staple cartridge and anvil to close the synchronization is complete suture. 当缝合完毕退出时，随着直切刀的后退辅以钉仓的弹性复位，钉仓与抵钉座逐步分开，此处与现有技术类似，在此不再赘述。 When the suturing is complete exit, with elastic return back straight cutter supplemented staple cartridge, the staple cartridge and the anvil progressively separated, where similar to the prior art, are not repeated here.
 其中，作为进一步的改进，为避免吻切机构与前中心杆和前推管连接处结构设置过多，所述的前中心杆和前推管分别为两段式结构，两段采用环凹槽和销钉的配合方式进行连接，将传动和导向结构分开设置，这样前端分别与对应部件固定连接即可，避免前端结构臃肿，提高空间利用率和运行平稳性。  wherein, as a further improvement, in order to avoid the push tube and the connecting structure of the front of the kiss-cutting means disposed before the center rod is too large, the front and the front center rod push tube are two-stage structure, using two ring groove and pin of fitting way to connect the drive and guide structure provided separately, so that the front end are fixed to the corresponding connecting member, the front end to avoid the cumbersome structure, space utilization and improve the running stability. 两段的连接方式与上述的环凹槽和销钉配合方式相似，在此不再描述。 Connection with the above-described two ring groove and the pin fitting in a similar manner, will not be described here.
