It can effectively remove and suture the tissue or blood vessels to be removed during surgery. Using the principle similar to the stapler can make the operation more convenient and cost-effective. Low.
管型吻合器作为吻合器的一种，常用在肛肠科或相似科室，其原理与大部分吻合器相同，均利用订书机的原理，在对组织进行切除的同时可对切口处进行缝合，此过程主要由钉仓组件完成。由于在切除和缝合手术时，钉仓组件一般位于体内或组织内，操作者无法直接从外界观察到缝合的情况，且由于操作或吻合器本身的问题，可能会导致缝合处缝合钉与组织缝合不充分的问题，即此时切除的组织仍然处于相互粘连状态，此时若直接取出吻合器会造成组织粘膜拉伤或缝合处撕裂，一方面对手术者造成了二次伤害，甚至会引发感染等问题，另一方面对手术过程会造成一定的影响。As a kind of stapler, tubular stapler is commonly used in anorectal department or similar departments. This process is mainly completed by the cartridge assembly. Since the staple cartridge assembly is generally located in the body or tissue during resection and suturing operations, the operator cannot directly observe the suturing from the outside world, and due to problems with the operation or the stapler itself, the staples at the suture may be sutured to the tissue. Insufficient problem, that is, the resected tissues are still in a state of mutual adhesion. If the stapler is directly removed at this time, the tissue mucosa will be pulled or the suture will be torn. On the one hand, it will cause secondary damage to the operator, and even cause Infection and other problems, on the other hand, will have a certain impact on the surgical process.

1、该用于管型吻合器的钉仓组件，通过所述卡块的内壁设置有定位槽结构，所述钉座的外侧设置有定位块结构，该定位块结构与该定位槽结构相适配，由于所述定位管、卡块、推杆、抵钉座总成和锥形头的轴线为同一条直线，所述定位孔的圆心位于抵钉座总成的中轴线上且尺寸与推杆的尺寸适配，将推杆的顶部插接在定位孔的内部，此时可完成该装置的拼接安装，上述过程可使该装置在使用时安装更加方便，减少了前期准备的时间，提高了手术的效率和质量。1. The staple cartridge assembly for tubular stapler is provided with a positioning groove structure through the inner wall of the clamping block, and a positioning block structure is provided on the outer side of the nail base, and the positioning block structure is suitable for the positioning groove structure. Since the axes of the positioning tube, the clamping block, the push rod, the anvil seat assembly and the conical head are the same straight line, the center of the positioning hole is located on the central axis of the anvil seat assembly and the size is the same as that of the push rod. The size of the rod is adapted, and the top of the push rod is inserted into the interior of the positioning hole, and the splicing and installation of the device can be completed at this time. efficiency and quality of surgery.
2、该用于管型吻合器的钉仓组件，通过使活动触点为长条状，所述固定触点与转杆中点的距离小于活动触点的尺寸，并且活动触点的长度小于转杆与钉位之间的距离，所以此时若九个钉位完全缝合充分，则活动触点会与缝合钉接触，此时缝合钉会在于活动触点接触后阻挡其位置，使其无法继续转动，即无法与固定触点接触，此时与固定触点外接的指示灯其线路为断开状态，即表示此时缝合完成且钉位准确，上述过程可实现该装置对缝合状态进行检测提示的目的，避免了因操作者无法直接观察到缝合结果而造成直接取出吻合器的情况，减少了对患者的伤害，提高了手术过程的安全性和可靠性。2. In the staple cartridge assembly for tubular stapler, by making the movable contact in a long strip shape, the distance between the fixed contact and the midpoint of the rotating rod is smaller than the size of the movable contact, and the length of the movable contact is less than The distance between the rotating rod and the nail position, so if the nine nail positions are fully sutured at this time, the movable contact will be in contact with the staple, and the staple will block its position after the movable contact is in contact, making it impossible to Continue to rotate, that is, it cannot be in contact with the fixed contact. At this time, the line of the indicator light connected to the fixed contact is disconnected, which means that the stitching is completed and the stitching position is accurate. The above process can realize the device to detect the stitching status. The purpose of the prompt is to avoid the situation of directly taking out the stapler because the operator cannot directly observe the suturing result, reduce the harm to the patient, and improve the safety and reliability of the operation process.

初始状态下，卡块93和抵钉座总成95之间呈分开状态，当需要对组织进行切除时，二者呈相互接触状态，此时钉座931内部的缝合钉从钉孔932中伸出，穿过待缝合的组织后与整形孔952接触，此时在钉座931的压力作用下缝合钉开始发生弯曲并最终形成“B”字形。In the initial state, the clamping
缝合完成后，使卡块93和钉座931向下旋转移动，由于转杆11和拉线10均有九个，九个转杆11以抵钉座总成95的圆心为参照呈均匀分布，即相邻两个转杆11之间的距离和角度均相同，九个转杆11分别与九个拉线10对应，九个拉线10远离转杆11的一端分别与九个副滑块152活动连接，初始状态下九个自锁机构15在水平方向上的高度相同，均位于限位槽14的底部，所以此时在拉线10的作用下转杆11和活动触点12可发生转动，活动触点12为长条状，固定触点13与转杆11中点的距离小于活动触点12的尺寸，并且活动触点12的长度小于转杆11与钉位之间的距离，所以此时若九个钉位完全缝合充分，则活动触点12会与缝合钉接触，此时缝合钉会在与活动触点12接触后阻挡其位置，使其无法继续转动，即无法与固定触点13接触，此时与固定触点13外接的指示灯其线路为断开状态，即表示此时缝合完成且钉位准确。After the stitching is completed, the clamping

由于限位槽14的内部设置有齿牙，活动杆153共有两个，两个活动杆153之间为铰接状态且铰接点位于副滑块152的正面，两个活动杆153之间活动连接有复位弹簧，两个活动杆153远离副滑块152的一端设置有齿状结构，该齿状结构与限位槽14内部的齿牙相适配，初始状态下，两个活动杆153在复位弹簧的作用下角度较大，活动杆153的齿状结构与限位槽14内部的齿牙啮合，此时主滑块151和副滑块152在限位槽14内部的位置相对固定，推杆94运动时可带动限位槽14和其内部的主滑块151和副滑块152同步运动。Since there are teeth inside the limiting
由于转杆11通过拉线10与副滑块152活动连接，所以当活动触点12转动至与缝合钉接触时，由于缝合钉限制活动触点12的位置，所以此时拉线10开始对副滑块152施加向上的拉力，此时两个活动杆153之间的角度减小，主滑块151可在限位槽14内部运动，即此时不影响其他结构的运动。Since the rotating
