装订仪保险机构Stapler Insurance Agency

技术领域technical field

本实用新型涉及一种用于外科装订仪的保险机构，尤其用于圆管型装订仪和PPH的装订仪保险机构，属于医疗器械领域。The utility model relates to a safety mechanism for a surgical binding instrument, in particular to a binding instrument safety mechanism for a circular tube binding instrument and a PPH, and belongs to the field of medical equipment.

技术背景technical background

外科用装订仪是对肠道等生理组织进行外科手术时经常使用的一种医疗器械，该仪器性能的差异对于整个手术效果起着至关重要的作用。为防止出现误击发，装订仪上一般设有保险装置。目前使用的装订仪保险大部分都是手动保险，也就是说，医生在给患者做手术时，需要在各项准备工作完成之后才能关闭保险状态，实施击发装订。通过实际使用发现，这种保险装置存在以下缺陷：若医生经验不足，装订间隙不到位时由于保险装置的保险状态也能被关闭而错误实施外科装订手术的装订，很容易导致手术效果不佳。或者，在换装装订仪头部组件时如若忘记开启保险状态，那么在手术实施过程中，只要使用者稍有不慎，就会触压击发扳手，导致装订针从仪器头部组件中击出，造成手术失败。虽然经过不断的努力，装订仪的保险机构做了很多改进，使装订仪在装订距离不合适时保险状态不能被关闭，减少了误击发的机会，但保险状态的关闭与否始终都只能手动完成，仍然存在操作不方便、费时费力等缺陷。Surgical stapler is a medical device often used in surgical operations on intestinal and other physiological tissues. The difference in the performance of the instrument plays a vital role in the overall surgical effect. In order to prevent misfiring, a safety device is generally provided on the binding instrument. Most of the currently used binding instrument insurances are manual insurances, that is to say, when doctors perform operations on patients, they need to close the insurance state after all preparations are completed, and implement firing and binding. Through actual use, it is found that this safety device has the following defects: if the doctor is inexperienced, the insurance state of the safety device can also be closed when the stapling gap is not in place, and the stapling of the surgical stapling operation is performed by mistake, which will easily lead to poor surgical results. Or, if you forget to turn on the safety state when changing the head assembly of the stapler, then during the operation, as long as the user is a little careless, the trigger wrench will be pressed, causing the staple to be ejected from the head assembly of the instrument. , causing the operation to fail. Although through continuous efforts, the insurance mechanism of the binding instrument has been improved a lot, so that the insurance state of the binding instrument cannot be closed when the binding distance is not suitable, reducing the chance of false firing, but the closing of the insurance state can only be done manually. Completed, there are still defects such as inconvenient operation, time-consuming and labor-intensive.

实施例1Example 1

如图1和图2所示：在把手2上设有的防脱装置为棘齿9。保险杆1依托在棘齿9上后，保证了保险杆1不会轻易摆动，也就是说，如果在手术过程中的某个阶段的吻合距离不合适，保险杆1与棘齿9呈现固定状态，把手2不能被压下，也就无法实现对装订仪的非正常击发，实现了一个最初步的保险功能。同时，通过保险杆1来限制把手2的运动的同时，经由拉片3的远端设有拉钩4，实现了拉片3与保险杆1的互动。如图2所示：当手术进行到一定过程后，使用者开始旋转装订仪的旋钮8，这样就同时带动了装订仪螺纹杆6的旋转运动。由于拉片3的近端5套置在螺纹杆6上，当螺纹杆6完全旋入旋钮时，螺纹杆6的远端带动拉片3运动，这样也随即带动了设置在拉片3远端的拉钩4，进而带动了保险杆1开始运动。最后保险杆1与把手2上的棘齿9完全脱开，装订仪属于保险关闭状态，就能够实施击发。在击发完毕后，复位弹簧7使保险杆1自动复位，这样即使在手术过程中换装装订仪头部组件，忘记使装订仪处于保险状态，也不会出现装订仪的误击发。此外，当吻合距离合适时即达到手术的要求时，手术实施者也可以通过手动拨动保险杆1，让保险杆1从把手2的棘齿9滑开，从而使保险处于关闭状态，实施装订仪的击发。As shown in FIGS. 1 and 2 : the anti-off device provided on thehandle 2 is aratchet 9 . After thesafety bar 1 rests on theratchet 9, it is ensured that thesafety bar 1 will not swing easily, that is to say, if the anastomosis distance is not suitable at a certain stage during the operation, thesafety bar 1 and theratchet 9 are in a fixed state , thehandle 2 cannot be pressed down, so the abnormal firing of the binding instrument cannot be realized, and a most preliminary insurance function is realized. At the same time, while the movement of thehandle 2 is restricted by thesafety rod 1 , thepull hook 4 is provided at the far end of thepull piece 3 to realize the interaction between thepull piece 3 and thesafety rod 1 . As shown in Fig. 2: when the operation is carried out to a certain process, the user starts to rotate theknob 8 of the binding instrument, which simultaneously drives the rotational movement of the threaded rod 6 of the binding instrument. Since theproximal end 5 of thepull piece 3 is sleeved on the threaded rod 6, when the threaded rod 6 is completely screwed into the knob, the far end of the threaded rod 6 drives thepull piece 3 to move, which also drives thepull piece 3 at the far end. Thedrag hook 4 further drives thebumper 1 to start moving. Finally, thesafety lever 1 is completely disengaged from theratchet 9 on thehandle 2, and the binding instrument belongs to the safety closed state, and the percussion can be implemented. After percussion is finished, returnspring 7 makessafety lever 1 reset automatically, even if change the binding instrument head assembly in the operation process like this, forget to make binding instrument be in safe state, also can not occur the mistake firing of binding instrument. In addition, when the anastomosis distance is suitable and the requirements of the operation are met, the operator can also manually toggle thesafety lever 1 to allow thesafety lever 1 to slide away from theratchet 9 of thehandle 2, so that the safety is in a closed state and the stapling is performed. The firing of the instrument.

实施例2Example 2

在把手上设有的防脱装置为卡块，具体操作过程与实施例1雷同，在此不再赘述。The anti-off device provided on the handle is a locking block, and the specific operation process is the same as that ofembodiment 1, and will not be repeated here.

除上述实施例外，本实用新型还可以有其它实施方式。凡采用等同替换或等效变换形成的技术方案，均落在本实用新型所要求保护的范围内。In addition to the above-mentioned embodiments, the utility model can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
