Push rod 4 offsets with flexible piece 812 and drives flexible piece 812 and remove, and flexible piece 812 passes through flexible seat 811 and drives barrier plate 9 and remove, and flexible piece 812 simultaneously drives guide block 83 and remove on inclined guide bar 82, and guide block 83 drives flexible piece 812 and rises, and flexible piece 812 shrink to the flexible inslot, and until the tip of push rod 4 breaks away from flexible piece 812, and flexible piece 81 no longer follows push rod 4 and removes.

The working principle of the invention is as follows:

When the tissue is clamped between the nail bin part 12 and the nail abutting part 11, the corresponding trigger plate 3 moves, the trigger plate 3 pushes the second hydraulic input rod 62 to move, the second hydraulic input rod 62 pushes hydraulic oil in the second hydraulic input cylinder 61 into the second hydraulic output cylinder 65 through the second hydraulic pipe 64, the hydraulic oil pushes the push rod 4 to move, when the push rod 4 moves to abut against the telescopic piece 81, the push rod 4 drives the telescopic piece 81 to synchronously move, the telescopic piece 81 drives the blocking plate 9 to move, the telescopic piece 81 drives the guide block 83 to move on the guide rod 82, the guide rod 82 is in an inclined arrangement, and when the inclined direction of the guide rod 82 enables the guide block 83 to move on the guide rod 82 in a direction far away from the push rod 4, The guide block 83 can synchronously move upwards under the inclination of the guide rod 82, the guide block 83 drives the telescopic piece 81 to shrink upwards until the end part of the push rod 4 is separated from the telescopic piece 81, the push rod 4 does not push the telescopic piece 81 to move any more, at the moment, the separation hole 91 on the blocking plate 9 coincides with the clamping indication hole, the bottom of the telescopic piece 81 is propped against the top of the push rod 4, the telescopic piece 81 cannot reset, the push rod 4 continues to move against the inclined surface of the inclined surface block 10, the inclined surface block 10 is lifted under the action of the inclined surface block 10, the inclined surface block 10 drives the indication block 5 to lift, the indication block 5 passes through the separation hole 91 and the clamping indication hole to extend out of the operation end 2, By observing the rising amount of the indication block 5, whether the anastomotic end 1 clamps the tissue in a large area can be judged, the tissue cutting and the anastomosing failure caused by the small tissue area clamped by the anastomotic end 1 are prevented, the using effect of the anastomat is increased, the cutting and anastomosing accuracy of the anastomat is improved, the tissue is clamped by the trigger plate 3, the friction force between the tissue and the tissue is improved, the operation stability of clamping the tissue is higher, when the tissue is clamped between the end part of the outer shell 121 and the nail propping part 11, the tissue pushes the moving plate 73 to move under the action of the clamping force, the moving plate 73 pushes the first hydraulic input rod 72 to move, the hydraulic oil is arranged in the first hydraulic input cylinder 71, the first hydraulic pipe 75 and the first hydraulic output cylinder 74, The first hydraulic input rod 72 moves to push the liquid in the first hydraulic input cylinder 71, the liquid enters the first hydraulic output cylinder 74 through the first hydraulic pipe 75, the indicating hydraulic rod 76 in the first hydraulic output cylinder 74 is pushed out, the indicating hydraulic rod 76 extends out through the end indicating hole, whether the end of the anastomat is clamped to the tissue can be judged through the extension of the indicating hydraulic rod 76, when the indicating hydraulic rod 76 is not lifted, the end part of the anastomotic end 1 is judged to be not clamped to the tissue when the indicating hydraulic rod 76 is not lifted, the middle part of the anastomotic end 1 is judged to be clamped to the tissue when the indicating block 5 is partially lifted, and whether the anastomotic end 1 penetrates the tissue to be clamped to the middle part of the anastomotic end 1 is judged to be passed through the tissue, When the indication hydraulic rod 76 is lifted, the end part of the anastomotic end 1 can be judged to clamp the tissue, the middle part of the anastomotic end 1 can also clamp the tissue when the indication hydraulic rod 5 is lifted, the area of the anastomotic end 1 clamped by the indication block 5 can be judged to prevent the problem of non-ideal anastomosis caused by too small area of clamped tissue, and the problem that when some narrower tissues such as intestinal tracts, protruding tissues and the like are clamped, the anastomotic end 1 of the anastomat penetrates through the tissues to clamp the tissues to the middle part of the anastomotic end 1 is solved, the clamping area is small at the moment, the lifting amount of the indication block 5 is small, and the problem that whether the anastomat clamps clamp the tissues to the middle part of the anastomotic end 1 cannot be judged is caused.

Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described above, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present invention.
