TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an anastomat butt pad assembly and a fixing method thereof. BACKGROUND

[0002] An anastomat is a surgical instrument used in medicine to replace manual suturing, and its main working principle is to use titanium nails to anastomose the severed tissue, similar to a stapler. Common surgical complications include bleeding, anastomotic fistula, anastomotic stenosis, etc. The current technology adds an absorbable reinforcing pad to consolidate the anastomotic strength, which can effectively reduce the occurrence of complications.

[0003] Because the absorbable material has high requirements for the environment and packaging, it is usually packaged separately or fixed on the anastomat for packaging together when leaving the factory; the high cost of packaging together with the anastomat brings a financial burden to the patient.

[0044] The present application will be described below in conjunction with the drawings:

[0045] An anastomat resistance pad assembly, which comprises an upper pad fixed frame and an upper pad arranged on the upper end surface of the resistance pad seat of an anastomat resistance pad seat, a lower pad fixed frame and a lower pad arranged on the lower end surface of the resistance pad seat of an anastomat nail bin;

[0046] The upper pad and the upper pad fixed frame are detachably connected;

[0047] The lower pad and the lower pad fixed frame are detachably connected;

[0048] The upper pad and the lower pad are correspondingly matched.

[0049] The upper pad and the lower pad of the present application are preferably thin film flexible pads, and the upper pad fixed frame and the lower pad fixed frame can make the upper pad and the lower pad closely adhere to each other, thereby achieving better adhesion.

[0050] The nail bin of the anastomat is internally provided with anastomat nails, and the lower end surface of the resistance pad seat is provided with nail pits matched with the anastomat nails. During anastomosis, the anastomat nails pushed out from the resistance pad seat pass through the lower pad, the tissue and the upper pad in sequence, thereby achieving the effect of anastomosis. The upper and lower pad fixed frames of the present application can be arranged on the lower end surface of the resistance pad seat and the upper end surface of the nail bin respectively, and are bent after being contacted by the anastomat nails and the nail pits of the resistance pad seat. In particular, the present application is suitable for the upper pad and the lower pad being thin film absorbable flexible pads, and the upper pad and the lower pad can be absorbed by the human body after several weeks after anastomosis.

[0051] In order to better illustrate the connection mode of the upper pad fixed frame and the lower pad fixed frame of the present application, the present application provides the following two specific embodiments of the anastomat resistance pad assembly:

[0052] Embodiment 1

[0053] The anastomat resistance pad assembly comprises an upper pad 1, a lower pad 2, an upper pad fixed frame 3 and a lower pad fixed frame 4;

[0054] The end surface of the upper pad 1 and the lower pad 2 is annular, and the middle part of the upper pad 1 is formed with an upper hollow protrusion 11 upward,

[0055] The middle part of the lower pad 2 is formed with a lower hollow protrusion 21 downward; the upper pad 1 and the lower pad 2 are thin film flexible pads;

[0056] 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 nail abutting seat 5. The end surface of the upper support seat 31 is a circular ring. The upper support seat 31 is connected with a plurality of upper support rods 32 downward. The upper support frame is sleeved in the upper protrusion 11 of the upper gasket 1. The diameter of the circular ring of the upper support seat 31 is slightly larger than the inner diameter of the upper protrusion 11. Since the upper gasket 1 is a flexible gasket of a film, the upper support seat 31 can be sleeved in the upper protrusion 11 of the upper gasket 1 at the same time. The end of the upper support rod 32 is bent outward to abut against the upper protrusion 11 of the upper gasket 1, thereby fixing the upper gasket 1. The upper support rod 32 is outwardly inclined relative to the upper support seat 31, so that the plurality of support rods have an outward tension relative to the upper gasket 1, thereby better fixing the upper gasket 1.

[0057] 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. The lower support seat 41 is connected with a plurality of lower support rods 42 upward. The lower gasket fixing frame 4 is at least sleeved in the lower protrusion 21 of the lower gasket 2. The diameter of the circular ring of the lower support seat 41 is slightly larger than the inner diameter of the lower protrusion 21 of the lower gasket 2. Since the lower gasket 2 is a flexible gasket of a film, the lower support seat 41 can be sleeved in the lower protrusion 21 at the same time. The end of the lower support rod 42 is bent outward to abut against the lower protrusion 21 of the lower gasket 2, thereby fixing the lower gasket 2. The lower support rod 42 is outwardly inclined relative to the lower support seat 41, so that the plurality of lower support rods 42 have an outward tension relative to the lower gasket 2, thereby better fixing the lower gasket 2.

[0058] In this embodiment, after the anastomosis is completed, the upper support rod 32 and the lower support rod 42 have limited outward tension. With a little force, 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.

[0059] Embodiment 2

[0060] This embodiment provides a stapler nail gasket assembly. The main components and connection modes are the same as those of embodiment 1. The difference lies in that the upper support seat 31 is connected with a plurality of upper fixed tongues 33 downward. The upper fixed tongue 33 is composed of an upper fixed rod 331 and an upper tongue end 332 formed by bending the upper fixed rod 331 outward. The upper tongue end 332 can extend to the lower side of the upper gasket 1 to buckle the upper gasket 1. The upper fixed tongue 33 and the upper support rod 32 are spaced apart from each other.

[0061] The lower support seat 41 is connected with a plurality of lower fixed tongues 43 upward. The lower fixed tongue 43 is composed of a lower fixed rod 431 and a lower tongue end 432 formed by bending the lower fixed rod 431 outward. The lower tongue end 432 can extend to the upper side of the lower gasket 2 to buckle the lower gasket 2. The lower fixed tongue 43 and the lower support rod 42 are spaced apart from each other.

[0062] The upper support rod 32 in the upper gasket fixing frame 3 abuts against the upper protrusion 11, and the upper tongue pressing end 332 of the upper tongue fixing 33 buckles the lower end surface of the upper gasket 1, thereby achieving better fixing effect. Similarly, the lower support seat 41 achieves better fixing effect of the lower gasket 2.

[0063] 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.

[0064] A fixing method of a staple abutting gasket assembly of an anastomat, specifically comprising the following steps: placing the upper gasket on the bottom surface of the anastomat staple abutting seat and fixing the upper gasket on the anastomat staple abutting seat through the upper gasket fixing frame; and placing the lower gasket on the top surface of the anastomat staple cartridge and fixing the lower gasket on the anastomat staple cartridge through the lower gasket fixing frame.

[0065] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the protection scope of the present application.
