Abstract

The invention relates to an anastomat, which comprises a body, a pin bin which is arranged on the body, a pin pushing plate which is arranged inside the pin bin, and a push rod which is arranged on the body and used for pushing the pin pushing plate, wherein the front end of the push rod is provided with a push part which contacts the pin pushing plate; the lower end face of the push part is flush with the lower end face of the pin pushing plate; and a limit stop is pressed below the pin pushing plate and connected with a reset mechanism which drives the limit stop to upspring. After the suturing process is over each time, the push rod can be retracted, the pin pushing plate is rested on the front of the pin bin, and the limit stop upsprings under the action of the reset mechanism and prevents the push rod from pushing the pin pushing plate to suture again, so that the anastomat has the function of locking the hollow pin bin and surgical failure can not be caused due to reutilization of the hollow pin bin.

Description

A kind of anastomat

Technical field

The present invention relates to a kind of anastomat of the usefulness of performing the operation.

Background technology

Used anastomat widely in the rectum low level resection operation, made operation safer.All do not have sky nail bin locking device in the general anastomat, sewing up finishes stitches nail in the nail bin afterwards, may operate because neglect, and makes operative failure, causes unnecessary accident.

Summary of the invention

The object of the present invention is to provide a kind of anastomat, apparatus is locked when empty nail bin, can't operate.

In order to reach above purpose, the scheme that the present invention adopts is:

A kind of anastomat, comprise body, be arranged on nail bin on the described body, be arranged on described nail bin inside pushing slice of nail, be arranged on the push rod that is used to promote described pushing slice of nail on the described body, described push rod front end has and the contacted pushing part of described pushing slice of nail, the lower surface of described pushing part is mutually concordant with the lower surface of pushing slice of nail, the below of described pushing slice of nail is pressed with a block, and this block is connected its resetting-mechanism that pops up with one.

One end of described block offers groove, an other end is rotatably connected on the described body, described response agency is a knee shape spring, one end of this spring stretches in the groove of described block, the other end and described body offset, and described spring is positioned at the Plane of rotation of described block.

The centrage of described groove and the sidewall of block at angle, this angle is between 5 °-10 °.

Because the present invention has adopted above technical scheme, so have advantage: owing to below the pushing slice of nail of nail bin inside, be pressed with a block, this block is connected with a resetting-mechanism, this resetting-mechanism pops up block, and the lower surface of pushing part is mutually concordant with the lower surface of pushing slice of nail, so will stitch nail and pushing slice of nail is packed into behind the nail bin, pushing slice of nail can be subdued block, push rod can promote pushing slice of nail and move forward, and carries out sew application; Push rod can be returned after stitching finished, and pushing slice of nail rests on the front portion of nail bin, block pops up under the effect of resetting-mechanism, stoping push rod to promote pushing slice of nail once more sews up, in the effect of having played locking, can not cause operative failure when seam is followed closely in nail bin because of reusing of empty nail bin.

Wherein: 1, body; 2, needle chamber; 3, nail bin base; 4, nail supporting base; 5, rotating shaft; 6, block; 7, groove; 8, spring; 9, pushing slice of nail; 10, push rod; 11, pushing part; 12, tip.

The specific embodiment

As shown in Figure 1, a kind of anastomat, comprise body 1, be arranged on the nail bin 2 on the body 1, be arranged on the pushing slice of nail 9 of nail bin 2 inside, be arranged on the push rod 10 that is used to promote pushing slice of nail 9 on the body 1, front end at body 1 in the present embodiment is fixedly connected with nail bin base 3, nail bin 2 and nail supporting base 4 all are arranged on this nail bin base 4, push rod 10 front ends have and pushing slice of nail 9 contacted pushing parts 11, empty nail bin can be locked afterwards for stitching is finished, the lower surface of pushing part 11 is mutually concordant with the lower surface of pushing slice of nail 9 among the present invention, and the below of pushing slice of nail 9 is pressed with a block 6, and this block 6 is connected its resetting-mechanism that pops up with one.

In order to save the space in the nail bin 2, present embodiment offers groove 7 on an end of block 6, nail bin base 3 on an other end and the body 1 is rotationally connected, above-mentioned response agency is a knee shape spring 8, one end of this spring 8 stretches in the groove 7 of block 6, nail bin base 3 on the other end and the body 1 offsets, and this spring 8 is positioned at the Plane of rotation of block 6.

In order to make the spring 8 can be to the bigger rotating torque of block, the sidewall of the centrage of present embodiment further groove 7 and block 6 at angle, this angle is between 5 °-10 °, as shown in Figure 6.

In the operation, need stitch earlier and follow closely and pushing slice of nail 9 nail bin 2 of packing into, pushing slice of nail 9 is depressed block 6, and the pushing part 11 of push rod 10 front ends props up pushing slice of nail 9, because the lower surface of pushing part 11 is mutually concordant with the lower surface of pushing slice of nail 9, shown in accompanying drawing 2 and accompanying drawing 3, at this moment control push rod 10 and move, can promote pushing slice of nail 9 and move forward, will stitch to follow closely to squeeze into and treat suture tissue, the seam nail pushes against with nail supporting base 4 and bends to " B " shape, finishes stitching.

After stitching finishes, push rod 10 can be return, but pushing slice of nail 9 can rest on the front portion of nail bin 2, block 6 is center rotation with rotating shaft 5 under the effect of spring 8, and its tip 12 is upturned, shown in accompanying drawing 4 and accompanying drawing 5, stop that push rod 10 promotes pushing slice of nail 9 once more, with 2 lockings of empty nail bin, pack into and can't operate again before the needle chamber 2 will stitch nail and pushing slice of nail 9 next time, played the effect of insuring.
