Problems solved by technology

[0004] However, because the staples used are multiple single nails, the assembly process is cumbersome and there is a problem that it is easy to miss. question
And, in the process of suturing tissue with surgical stapler, there is a situation where the staples are empty and closed (that is, the staples are closed without suturing the tissue). Since the staples used are multiple single nails, the nails will be scattered in the body. This also requires additional means to clean the nails, reducing surgical efficiency

Embodiment 1

[0044] In order to solve the technical problems in the background technology, this embodiment provides a staple strip. Such as figure 1 As shown, the staple strip includes a strip support strip 1 and a plurality of staple legs 2, the first end of each staple leg 2 is connected to the strip support strip 1, and the second end of each staple leg 2 is free. end; the plurality of nail legs 2 are arranged in sequence along the extension direction of the strip support band 1, and the plurality of nail legs 2 are arranged in the same plane; during the sewing process, the second end of each nail leg 2 faces toward the tissue, the staple belt moves along the facing direction of the second end of the staple leg, and the second end of each staple leg 2 can be inserted into the tissue to be sutured. In order to stabilize the suture tissue, in the staple strip provided in this embodiment, adjacent staple legs are parallel to each other, and the distance between adjacent staple legs is equ...

Embodiment 2

[0067] The main difference between this embodiment and embodiment 1 is:

[0068] Such as Figure 6As shown, the nail-resisting bosses 44 are arranged at equal intervals along the rolling surface 43 of the nail-push rolling plate 41. During the rolling process of the nail-pushing rolling plate 41 along the far-near direction, the nail-repelling bosses 44 are used to resist the nails on the nail belt. Staple leg 2 sutures tissue. By setting the nail-resisting boss 44 to act on the nail legs 2 on the nail belt to suture the tissue, the stress is concentrated and the requirement on the strength of the nail-pushing rolling plate 41 is reduced.

[0069] Preferably, the nail anvil bosses 44 are arc-shaped platforms, and two adjacent nail anvil bosses 44 are arranged close to each other.

[0070] The rest of the similarities with Embodiment 1 will not be repeated here.

Abstract

The invention provides a driving device for suturing nails. The driving device comprises a nail bin and a nail pushing roller accommodated in the nail bin, the top end of the nail bin is provided with a nail groove which extends into the nail bin, extends in the far-near direction and is used for containing a suturing nail belt, and a clamping structure used for sequentially clamping the suturing nail belt from the near end to the far end of the suturing nail belt is arranged in the nail groove. The nail pushing roller is installed in the nail bin in a rolling mode in the far and near direction and provided with a nail pushing rolling piece arranged around the rolling axis, the nail pushing rolling piece is upwards inserted into the nail groove, and the nail pushing rolling piece is always inserted into the nail groove in the process that the nail pushing roller drives the nail pushing rolling piece to roll in the far and near direction. The rolling face of the nail pushing rolling piece is used for pushing the suturing nail belt to be inserted into tissue. The suturing nail belt can be driven to suture tissues, and the suturing effect is good. The invention further provides a surgical stapler with the suturing nail driving device.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a staple driving device and a surgical stapler. Background technique [0002] With the development of medical devices, more and more multi-functional staple products are used clinically. An essential auxiliary medical device in the tissue suturing process. The application of surgical stapler has many advantages such as less blood loss during operation, shorter operation time, reduction of manual operation error, avoidance of infection, and quick recovery of postoperative function. [0003] The staples used in the surgical stapler are usually a plurality of single staples. A staple driving device is arranged in the nail bin of the surgical stapler. The staple driving device includes a pusher roller that can move along the far-near direction and a plurality of staples that can The nail pusher moves up and down, the bottom of the staple is clamped on the top of the nai...
