When motor 41 drives, the output shaft 411 of motor 41 drives threaded screw rod 42 rotations, during threaded screw rod 42 rotation, drive follower 43 to move along the length direction of threaded screw rod 42, follower 43 drives transmission component 44 to move along the bearing of trend of slender bodies 2 while moving, transmission component 44 is in transmission connection with end effector 3, and then drives end effector 3 to curve by transmission component 44.

Above-mentioned follower 43 can be any and parts threaded screw rod 42 threaded engagement; shape is not defined as bulk yet; semiellipse ball-type or dome-type can, the follower 43 shown in Fig. 3 and Figure 10 is only to enumerate a kind of concrete structure, and non-limiting protection domain of the present utility model.

Further, being in transmission connection between threaded screw rod 42 and motor 41 can be realized by following manner:

Mode one, please continue to refer to Fig. 3, is coaxially fixed with driving gear 412 on the output shaft 411 of motor 41, is coaxially fixed with the driven gear 421 with driving gear 412 engagements on threaded screw rod 42.

Between the output shaft 411 of threaded screw rod 42 and motor 41, by intermeshing driving gear 412 and driven gear 421, realized and being in transmission connection, the stable row of the kind of drive of gear engagement is higher.

Mode two, is connected (concrete structure of shaft coupling is not shown) by shaft coupling transmission between the output shaft 411 of motor 41 and threaded screw rod 42.

In a kind of preferred implementation, as shown in Figure 3, the end effector 3 of above-mentioned surgical operating instrument comprises enforcement division 32 and connecting portion 31, and the enforcement division 32 in end effector 3 is articulated in connecting portion 31 by pivotal axis, and connecting portion 31 is connected with slender bodies 2; The above-mentioned transmission component 44 that curves control device can comprise:

One end of first driving member 442, the first driving members 442 that can move along the bearing of trend of the connecting portion 31 of end effector 3 is connected with enforcement division 32, and the first driving member 442 drives enforcement division 32 to curve while moving;

Second driving member 441, the second driving members 441 that can move along the bearing of trend of slender bodies 2 are in transmission connection with follower 43, and are in transmission connection with the first driving member 442.

Motor 41 drives threaded screw rod 42 rotations by output shaft 411, threaded screw rod 42 drives follower 43 to move along the bearing of trend of threaded screw rod 42, because the second driving member 441 is in transmission connection with follower 43, when therefore, follower 43 moves, drive the second driving member 441 to move along the bearing of trend of slender bodies 2; Between the second driving member 441 and the first driving member 442, be in transmission connection, the second driving member 441 drives the first driving member 442 to move along the length direction of connecting portion 31 when the bearing of trend of slender bodies 2 slides, and then the push-and-pull of realization to enforcement division 32 in end effector 3, and then drive enforcement division 32 to rotate around itself and the pivotal axis between connecting portion 31, realize enforcement division 32 curving with respect to slender bodies 2.

The kind of drive between above-mentioned the second driving member 441 and follower 43 is not limit, preferably, between the second driving member 441 and follower 43 by fixture block and draw-in groove clamping.

Above-mentioned the second driving member 441 can be driver blade, can be also drive link.

The kind of drive between above-mentioned the second driving member 441 and the first driving member 442 is not limit, preferably, between the first driving member 442 and the second driving member 441 by fixture block and draw-in groove clamping.

Particularly, above-mentioned surgical operating instrument is preferably stapler.

Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model this utility model embodiment.Like this, if within of the present utility model these are revised and modification belongs to the scope of this utility model claim and equivalent technologies thereof, this utility model is also intended to comprise these changes and modification interior.
