本发明涉及医疗器械技术领域，特别涉及一种吻合器的保险调节装置。本发明还涉及一种包括上述保险调节装置的吻合器。The invention relates to the technical field of medical instruments, in particular to a safety adjustment device for a stapler. The present invention also relates to a stapler comprising the above-mentioned safety adjusting device.
背景技术Background technique
在医学科学的外科手术中，自从20世纪60年代发明第一把缝钉类产品以来，医用吻合器已成为辅助于刀口缝合过程中的必不可少的一种医疗器械。随着医学的发展和产品研发，越来越多功能的缝钉类产品应用于临床。适用范围已涉及到胃肠外科、肝胆外科、胸外科、泌尿外科、妇产科等各个领域，成为医生必不可少的工具之一。对于患者具有术中较少出血、较少手术时间、用器械代替手工从而减少由于手工而造成的误差、避免感染、术后功能恢复快等多种优势。In the surgical operation of medical science, since the first staple product was invented in the 1960s, the medical stapler has become an indispensable medical device to assist in the process of incision suturing. With the development of medicine and product research and development, more and more multifunctional staple products are used in clinical practice. The scope of application has been involved in various fields such as gastrointestinal surgery, hepatobiliary surgery, thoracic surgery, urology, obstetrics and gynecology, and has become one of the indispensable tools for doctors. For patients, it has many advantages such as less blood loss during operation, less operation time, using instruments instead of manual operation to reduce errors caused by manual operation, avoiding infection, and quick recovery of postoperative function.
一种典型的吻合器的保险装置，包括活动手柄、直推杆、保险挡板，保险挡板安装在直推杆上，活动手柄上设置有保险钩。吻合器的初始状态，保险挡板位于保险钩的上方，由于保险档板的阻挡，活动手柄无法闭合，当旋转固定手柄上的旋转手柄，旋转手柄旋转到合适位置时，吻合器的指针指向绿色区域，此时保险挡板移开保险钩的上方，即活动手柄可以握合。A typical safety device of a stapler includes a movable handle, a straight push rod, and a safety baffle, the safety baffle is installed on the straight push rod, and a safety hook is arranged on the movable handle. In the initial state of the stapler, the safety baffle is above the safety hook. Due to the blocking of the safety baffle, the movable handle cannot be closed. When the rotating handle on the fixed handle is rotated and the rotating handle is rotated to a proper position, the pointer of the stapler points to green At this time, the safety baffle is moved away from the top of the safety hook, that is, the movable handle can be gripped.
但由于吻合器装配过程存在装配精度的问题，当旋转手柄旋转到合适位置时，保险挡板的位置依然在保险钧的上方；有时旋转手柄没有旋转到合适位置时，保险挡板移开了保险钩的上方，导致保险失效。However, due to the problem of assembly accuracy in the assembly process of the stapler, when the rotating handle is rotated to the proper position, the position of the safety baffle is still above the safety juncture; sometimes when the rotating handle is not rotated to the proper position, the safety baffle is removed above the hook, causing the safety to fail.
因此，如何提高吻合器的保险装置的精度，是本领域技术人员目前需要解决的技术问题。Therefore, how to improve the precision of the safety device of the stapler is a technical problem to be solved by those skilled in the art.

具体实施方式detailed description
本发明的目的是提供一种吻合器的保险调节装置，该保险调节装置可以调节吻合器的保险挡板，吻合器的保险的精度较高。本发明的另一目的是提供一种包括上述保险调节装置的吻合器。The purpose of the present invention is to provide a safety adjustment device for a stapler, which can adjust the safety baffle of the stapler, and the safety precision of the stapler is high. Another object of the present invention is to provide a stapler comprising the above safety adjustment device.
为了使本领域技术人员更好地理解本发明的技术方案，下面将结合附图和具体实施例对本发明作进一步的详细说明。In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
请参考图1-图2，在一种具体实施方式中，本发明实施例提供的吻合器的保险调节装置，包括直推杆3和保险挡板5，还包括与直推杆3滑动连接且能够与直推杆3相对固定的保险调节块4，保险挡板5与保险调节块4连接。在组装完吻合器后，旋转吻合器的旋转手柄2，将吻合器调节到合适状态，如果此时活动手柄1正好可以握动，即吻合器的保险准确；如果此时不能握动手柄或活动手柄1的保险钩11与保险挡板5距离较大，即可通过改变保险调节块4的位置，从而将保险挡板5调节到合适的位置，此时的吻合器的保险装置较精确。本发明实施例提供的吻合器的保险调节装置，可以移动保险调节块4从而使保险调节到精准的位置，从而提高了吻合器的保险装置的精度。上述保险调节块4上可以设置有第一固定孔，第一固定孔内设置有固定螺钉8，从而将保险调节块4固定在直推杆3上。Please refer to Fig. 1-Fig. 2, in a specific embodiment, the safety adjustment device of the stapler provided by the embodiment of the present invention includes a straight push rod 3 and a safety baffle 5, and also includes a sliding connection with the straight push rod 3 and The insurance adjusting block 4 that can be relatively fixed with the straight push rod 3 , and the insurance baffle 5 is connected with the insurance adjusting block 4 . After assembling the stapler, rotate the rotary handle 2 of the stapler to adjust the stapler to a suitable state. If the movable handle 1 can be held just right at this time, that is, the safety of the stapler is accurate; The distance between the safety hook 11 of the handle 1 and the safety baffle 5 is relatively large, and the safety baffle 5 can be adjusted to a proper position by changing the position of the safety adjustment block 4, and the safety device of the stapler at this time is more accurate. The safety adjustment device of the stapler provided by the embodiment of the present invention can move the safety adjustment block 4 to adjust the safety to a precise position, thereby improving the accuracy of the safety device of the stapler. The safety adjustment block 4 may be provided with a first fixing hole, and a fixing screw 8 is arranged in the first fixing hole, so that the safety adjustment block 4 is fixed on the straight push rod 3 .
此外，保险调节块4可以为L型，L型占用空间较小，且与直推杆3的配合较稳定。In addition, the safety adjustment block 4 can be L-shaped, which takes up less space and is more stable in cooperation with the straight push rod 3 .
另外，保险调节块4可以为U型，U型在直推杆3上受力稳定，不易脱落，且在移动时较容易操作。In addition, the safety adjustment block 4 can be U-shaped, and the U-shaped push rod 3 is stable in force, not easy to fall off, and easier to operate when moving.
进一步地，第一固定孔为长条固定孔，这样在移动保险调节块4时，不用移动固定螺钉8，只移动保险调节块4，更加的便捷，且避免了在直推杆3上设置太多的螺孔而导致直推杆3强度变低。Further, the first fixing hole is a strip fixing hole, so that when moving the safety adjustment block 4, only the safety adjustment block 4 is moved without moving the fixing screw 8, which is more convenient and avoids setting too much on the straight push rod 3. Many screw holes cause straight push rod 3 intensity to become low.
更进一步地，保险调节块4为弹性U型调节块，弹性U型调节块夹在直推杆3上。保险调节块4具有弹性且可以夹在直推杆3上，这样可以快速移动保险调节块4且较容易安装。Furthermore, the insurance adjustment block 4 is an elastic U-shaped adjustment block, and the elastic U-shaped adjustment block is clamped on the straight push rod 3 . The safety adjustment block 4 is elastic and can be clamped on the straight push rod 3, so that the safety adjustment block 4 can be moved quickly and is easier to install.
此外，还包括直推杆3滑动连接且能够与直推杆3相对固定的指针调节块6，指针调节块6与吻合器的指针7抵接。指针调节块6与保险调节块4配合，使吻合器的精度更高。In addition, it also includes a pointer adjustment block 6 that is slidably connected with the straight push rod 3 and can be relatively fixed with the straight push rod 3 . The pointer adjustment block 6 abuts against the pointer 7 of the stapler. The pointer adjustment block 6 cooperates with the safety adjustment block 4, so that the accuracy of the stapler is higher.
另外，上述指针调节块6上可以设置有第二固定孔，第二固定孔内设置有固定螺钉，从而将指针调节块6固定在直推杆3上。In addition, the pointer adjustment block 6 may be provided with a second fixing hole, and a fixing screw is arranged in the second fixing hole, so that the pointer adjustment block 6 is fixed on the straight push rod 3 .
进一步地，第二固定孔为长条固定孔，这样在移动指针调节块6时，不用移动固定螺钉，只移动指针调节块6，更加的便捷，且避免了在直推杆3上设置太多的螺孔而导致直推杆3强度变低。Further, the second fixing hole is a strip fixing hole, so that when moving the pointer adjustment block 6, only the pointer adjustment block 6 is moved without moving the fixing screw, which is more convenient and avoids setting too many screws on the straight push rod 3. The screw holes of the straight push rod 3 are reduced in strength.
