[0029] Embodiment 1:

[0030] See also Figure 1 The utility model discloses a device for removing a jammed nail in an ENDOGIA nail magazine, comprising a handle 1, a rod body 2 is fixedly connected to the handle 1, and a release component for removing a jammed nail in an ENDOGIA nail magazine is provided at the end of the rod body 2;

[0031] The releasing component at least includes a hook rod 3 which has an angle with the rod body 2 .

[0032] In this embodiment, the hook rod 3 is inserted into the blade slot of the staple cartridge and then pulled back, thereby achieving the effect of eliminating the ENDO GIA staple jam failure.

[0033] Embodiment 2:

[0034] See also Figure 2 - Figure 6Different from the first embodiment, a mounting seat 4 is fixedly connected to the top of the rod body 2, a slide groove is provided on the mounting seat 4, the hook rod 3 is slidably connected to the slide groove on the mounting seat 4 through a slider, and a driving component 5 for driving the hook rod 3 to move is also provided on the rod body 2.

[0035] The driving component 5 includes a rotating rod 51 that rotates under the obstruction of the suture needle. The rotating rod 51 is rotatably mounted on the mounting seat 4 through a rotating shaft. The rotating shaft is also provided with a gear 52 that rotates synchronously with the rotating rod 51. A rack 53 is meshed between the teeth of the gear 52, and the rack 53 is mounted on the side of the hook rod 3 parallel to the slide groove.

[0036] The driving component 5 also includes a rebound unit, which is used to rotate the rotating rod 51 so that the suture staple is clamped between the rotating rod 51 and the hook rod 3.

[0037] The driving component 5 also includes an anti-drop component arranged between the hook rod 3 and the rotating rod 51.

[0038] The anti-drop component includes a limit rod 6 connected to the hook rod 3 and rotatably away from the head end. The limit rod 6 is installed on the hook rod 3 through a rotating shaft and another resilient component. A fitting groove 7 for installing the limit rod 6 is provided at the bottom of the hook rod 3. The hook rod 3 is installed inside the fitting groove 7.

[0039] The rotating rod 51 is provided with an opening 9 for accommodating the rotating limiting rod 6.

[0040] When this embodiment is used, the rotating rod 51 can be first inserted into the blade slot of the staple cartridge, and then pushed upward to make the rotating rod 51 contact with the stuck suture staple and then subjected to force. When the rotating rod 51 is subjected to force, the gear 52 is rotated through the rotating shaft, and the gear 52 rotates to extend the hook rod 3 above the suture staple through the rack 53, so that the hook rod 3 is inserted into the blade slot and is located above the stuck suture staple. Compared with the first embodiment, the hook rod 3 can be blindly inserted, which effectively saves the time of inserting the hook rod 3 into the inside of the blade slot of the staple cartridge;

[0041] See also Figure 5 When it is sensed that the rotating rod 51 cannot rotate, the hook rod 3 is in the longest state of extending into the blade groove, wherein the limit rod 6 on the hook rod 3 is automatically opened under the action of the corresponding rebound unit, and then the handle 1 is pulled back to reset the rotating rod 51 under the action of the corresponding rebound unit. During the resetting process, the limit rod 6 will be stuck in the opening 9 of the rotating rod 51 and move in the opening 9 under the resetting of the hook rod 3, so that the hook rod 3, the limit rod 6 and the rotating rod 51 surround the suture nail of the clamping column, thereby preventing the suture nail from falling when the staple is released from the staple magazine.

[0042] Embodiment three:

[0043] See also Figure 7, which is different from the second embodiment, the anti-drop component is a corresponding slot 8 provided on the rotating rod 51 and the hook rod 3.

[0044] When this embodiment is used, the resetting of the rotating rod 51 can cause the suture staple to be stuck between the rotating rod 51 and the hook rod 3, and the provision of the clamping groove 8 can further prevent the suture staple from falling off.

[0045] In the second embodiment and the third embodiment, preferably, the rebound unit is a torsion spring installed on the rotating shaft.

[0046] The above is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
