Detailed ways

The present invention will be described below in conjunction with the accompanying drawings:

A stapler-anchoring gasket assembly, which comprises an upper gasket fixing frame arranged on the stapler anvil seat and an upper gasket on the lower end surface of the stapler anvil seat, a lower gasket fixing frame arranged on the stapler staple cartridge, and lower gasket;

The upper gasket and the upper gasket fixing frame are detachably connected;

The lower gasket and the lower gasket fixing frame are detachably connected;

The upper gasket and the lower gasket are matched correspondingly.

In the present invention, the upper gasket and the lower gasket are preferably thin film flexible gaskets. When they are matched, the upper gasket fixing frame and the lower gasket fixing frame can make the upper gasket and the lower gasket closely fit, so as to achieve better adhesion. combined effect.

The staple cartridge of the stapler is provided with staples, and the lower end surface of the staple seat can be provided with staple pits matched with the staples. During anastomosis, the staples pushed out from the anvil seat pass through the lower gasket, the tissue and the upper gasket in sequence to achieve the effect of anastomosis. The upper and lower gasket fixing brackets of the present invention can be respectively arranged on the lower end face of the anvil seat and the upper end face of the staple cartridge, and are bent after the pushed out staples are in contact with the nail pits of the anvil seat. The pads and the lower pads are thin absorbable flexible pads that can be absorbed by the body for several weeks after anastomosis.

In order to better illustrate the connection mode of the upper gasket fixing frame and the lower gasket fixing frame of the present invention, the present invention provides the following two specific embodiments of the stapler butt pad assembly:

Example 1

The stapler stapling spacer assembly includes an upper spacer 1, a lower spacer 2, an upper spacer fixing frame 3 and a lower spacer fixing frame 4;

The end faces of the upper gasket 1 and the lower gasket 2 are annular, and a hollow upper protrusion 11 is formed in the middle of the upper gasket 1 upward.

A hollow lower protrusion 21 is formed downward in the middle of the lower gasket 2; the upper gasket 1 and the lower gasket 2 are thin film flexible gaskets;

The upper gasket fixing frame 3 is composed of an upper support seat 31 and an upper support rod 32. The upper support seat 31 is fixed in the inner cavity of the anvil seat 5. The end face of the upper support seat 31 is a circular ring, and the upper support seat 31 is connected downward with several The upper support rod 32; the upper support frame is sleeved in the upper protrusion 11 of the upper gasket 1, and the diameter of the ring of the upper support seat 31 can be slightly larger than the inner diameter of the upper protrusion 11, because the upper gasket 1 is a flexible film. The gasket can make the upper support seat 31 sleeved in the upper protrusion 11 of the upper gasket 1 at the same time; For the function of the gasket 1, the upper support rod 32 is inclined outwardly relative to the upper support seat 31, so that several support rods have outward tension relative to the upper gasket 1, which has a better effect of fixing the upper gasket 1;

Similarly, the lower gasket fixing frame 4 is composed of a lower support seat 41 and a lower support rod 42, the lower support seat 41 is fixed in the inner cavity of the nail cartridge 6, the end surface of the lower support seat 41 is a circular ring, and the lower support seat 41 is connected upwardly There are several lower support rods 42; the lower gasket fixing frame 4 at least makes the lower support frame sleeved in the lower protrusion 21 of the lower gasket 2, and the diameter of the ring of the lower support seat 41 can be slightly larger than the lower protrusion of the lower gasket 2. 21, since the lower gasket 2 is a flexible gasket with a thin film, the lower support seat 41 can be simultaneously sleeved in the lower protrusion 21; The protrusions 21 play the role of fixing the lower gasket 2, and the lower support rods 42 are inclined outwardly relative to the lower support base 41, so that several lower support rods 42 have outward tension relative to the lower gasket 2, which plays a more The effect of fixing the lower gasket 2 is good.

After the anastomosis in this embodiment, since the outward tension of the upper support rod 32 and the lower support rod 42 is limited, the upper spacer fixing frame 3 and the lower spacer fixing frame 4 can be connected to the upper spacer 1 and the lower spacer respectively with a little force. Gasket 2 is phase separated.

Example 2

This embodiment provides a stapler abutment gasket assembly, the main components and connection methods of which are the same as those in Embodiment 1, except that the upper support base 31 is connected downward with a plurality of upper fixed pressing tongues 33, and the upper fixed pressing tongues 33 are upper The fixing rod 331 and the upper fixing rod 331 are bent outwardly to form an upper pressing tongue end 332. The upper pressing tongue end 332 can extend to the lower side of the upper gasket 1 to fasten the upper gasket 1; the upper fixed pressing tongue 33 and the upper support The rods 32 are spaced apart from each other;

The lower support base 41 is upwardly connected with a plurality of lower fixed pressing tongues 43. The lower fixed pressing tongues 43 are formed by the downward pressing tongue ends 432 formed by the outward bending of the lower fixing rod 431 and the lower fixing rod 431. The downward pressing tongue ends 432 can extend to The upper side of the lower gasket 2 is fastened to the lower gasket 2; the lower fixed pressing tongue 43 and the lower support rod 42 are arranged at intervals from each other.

This embodiment realizes that the upper support rod 32 in the upper gasket fixing frame 3 is pressed against the upper protrusion 11, and at the same time, the upper pressing tongue end 332 of the upper fixing pressing tongue 33 is fastened to the lower end surface of the upper gasket 1, which plays a better role. fixed effect. Similarly, the lower support seat 41 has a better effect of fixing the lower gasket 2 .

In this embodiment, after the anastomosis is completed, the upper gasket fixing frame 3 and the lower gasket fixing frame 4 can be separated from the upper gasket 1 and the lower gasket 2 respectively.

A method for fixing a stapler gasket, the specific operation is as follows: placing an upper gasket on the bottom surface of the stapler anbutment seat and fixing the upper gasket on the stapler anbutment seat through an upper gasket fixing frame; The spacer is placed on the top surface of the staple cartridge, and the lower spacer is fixed on the staple cartridge through the lower spacer fixing frame.

Finally, it should be noted that the above is only the preferred embodiments of the present invention, and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it is still The technical solutions described in the foregoing embodiments can be modified, or some technical features thereof can be equivalently replaced. Any modifications, equivalent replacements, improvements, etc. made on the basis of the spirit and principle of the present invention shall be included in the beyond the scope of protection of the present invention.
