Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, as shown in fig. 2, an embodiment of the present invention is a curved pushing tube seat for a tubular anastomat, including a sleeve 1, a curved pushing tube seat 2 is sleeved on the sleeve 1, a groove 3 is provided at the inner side of the curved pushing tube seat 2, the groove 3 is used for cooperating with a slider 4, so that the curved pushing tube seat 2 can rotate along the central axis of the sleeve 1, and a sliding groove 5 is provided on the surface of the sleeve 1, so that the slider 4 can move along the sliding groove 5, and can drive the curved pushing tube seat 2 to slide on the sleeve 1, an annular blocking piece 6 is further provided in the sleeve 1 at a gap, and a spring 7 is provided between the annular blocking piece 6 and the sleeve 1, so as to buffer the curved pushing tube seat 2 in the sliding process, and also reset the curved pushing tube seat 2.

Through set up curved push tube seat 2 outside sleeve pipe 1, curved push tube seat 2 cooperates with slider 4 to be connected with spring 7 through slider 4, make the cast anastomat when taking out, play the effect of a buffering to the cast anastomat through spring 7, reduce because of taking out the effect that the too big influence of range was sewed up, simultaneously the utility model provides a curved push tube seat 2 for cast anastomat simple structure easily promotes.

Still refer to fig. 1, in another embodiment of the present invention, in order to make the tubular anastomat in the process of rotation, reduce and lead to the suture to split because of the turned angle is too big, through set up recess 3 in curved thrust bearing 2 inboard, the longitudinal section of this recess 3 is the T font, and this recess 3 is identical with above-mentioned slider 4, a central axis that is used for making curved thrust bearing 2 can follow sleeve pipe 1 is rotatory, still can hold curved thrust bearing 2 and the rotatory angle is confirmed to the angle on the curved thrust bearing 2 of accessible, observe rotatory angle through the scale on the curved thrust bearing 2 simultaneously, so as to avoid leading to the suture not hard up or split because of the rotation angle is too big.

Referring to fig. 1 and 2, in order to reduce the effect of suture caused by force discomfort when the tubular anastomat is taken out from the suture, in the preferred embodiment of the invention, a spring 7 is arranged in the sleeve 1, the axial length of the spring 7 is the same as the length of the annular stopper 6, one end of the spring 7 is fixedly connected with the slider 4, and the slider 4 is matched with the chute 5, when the tubular anastomat is taken out from the suture, the tubular anastomat is slowly taken out through the mutual matching between the bending and pushing tube base 2 and the sleeve 1, meanwhile, the bending and pushing tube base 2 is slowly moved to the suture by force during the taking-out process, and the bending and pushing tube base 2 slowly compresses the spring 7 under the action of external force during the taking-out process, and plays a role of buffering when the tubular anastomat is taken out through the spring 7, so as to avoid the effect of sewing influenced by uneven taking-out amplitude or overlarge taking-out amplitude; furthermore, the sliding groove 5 is parallel to the central axis of the sleeve 1, and the length of the sliding groove 5 is the same as the depth of the bending and pushing tube seat 2, so that the bending and pushing tube seat 2 can conveniently slide on the sleeve 1, meanwhile, the bending and pushing tube seat 2 is in a hollow ring shape and is arranged in a gap with the sleeve 1, and the sliding groove is used for enabling the tubular anastomat to shake in the bending and pushing tube seat 2 through the anastomat in the process of taking out the tubular anastomat, can keep the shaking amplitude consistent, and plays a role in protecting the sewing position.

Referring to fig. 1, fig. 3 and 4, in another embodiment of the present invention, in order to facilitate the sliding of the bending pushing tube base 2 on the sleeve 1, the longitudinal section of the above-mentioned sliding block 4 is T-shaped or inverted T-shaped, when using the tubular anastomat, the bending pushing tube base 2 can rotate along the axis of the sleeve 1, and the bending pushing tube base 2 keeps stationary relative to the sleeve 1 when rotating, in this embodiment, the sliding blocks 4 are two, and are symmetrical about the central axis of the bending pushing tube base 2, and the sliding slots 5 are the same as the sliding blocks 4, and the sliding blocks 4 are matched with the sliding slots 5, and when the bending pushing tube base 2 slides relative to the sleeve 1, the sliding blocks 4 slide on the sliding slots 5, and are stationary relative to the bending pushing tube base 2.
