Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an anastomat gasket fixing device. BACKGROUND

[0002] An anastomat is a device 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 gasket to consolidate the strength of the anastomotic stoma, 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 at the factory and packaged together. The high cost of packaging with the anastomat puts a financial burden on patients. SUMMARY

[0004] The purpose of the present application is to provide an anastomat gasket fixing frame for mounting the upper and lower gaskets on the anvil seat and the nail cartridge, respectively, in view of the above-mentioned shortcomings and deficiencies of the prior art.

[0005] The purpose of the present application is achieved as follows:

[0006] An anastomat gasket fixing device comprises a fixing frame body, an upper gasket and a lower gasket, the upper end surface of the fixing frame body is provided with an upper fixing part detachably connected with the upper gasket, and the lower end surface is provided with a lower fixing part detachably connected with the lower gasket; the side surface of the upper gasket and the lower gasket is provided with a gasket fixing film. In the present application, the upper gasket can be bonded to the lower end surface of the anastomat anvil seat, and the lower gasket can be bonded to the upper end surface of the anastomat nail cartridge; the anastomat gasket fixing device of the present application is particularly suitable for all anastomats with separate upper and lower gaskets. For example, the upper end of the anastomat gasket fixing device of the present application is buckled with the lower end surface of the anastomat anvil seat to achieve the installation of the upper gasket, and the lower end is buckled with the anastomat nail cartridge to achieve the installation of the lower gasket. The device can simultaneously buckle the anastomat anvil seat with the upper end of the fixing frame column body and the nail cartridge with the lower end of the fixing frame column body, thereby achieving the simultaneous installation of the upper and lower gaskets and improving the installation efficiency.

[0007] The anastomat gasket fixing device can be optionally provided with an upper limiting column arranged on the upper end surface of the fixing frame body, and a lower limiting column arranged on the lower end surface of the fixing frame body, and the upper and lower gaskets can be respectively sleeved on the upper and lower limiting columns. The upper and lower limiting columns can be provided with protrusions to limit the upper and lower gaskets.

[0008] The upper limiting column has a cross-sectional diameter larger than the inner diameter of the upper gasket, and the lower limiting column has a cross-sectional diameter larger than the inner diameter of the lower gasket. Since the upper gasket and the lower gasket are generally made of flexible material, the cross-sectional diameter of the upper limiting column is larger than the inner diameter of the upper gasket, and the outward stretching and contraction of the upper gasket can be achieved by sleeving the upper limiting column, thereby realizing detachable connection. Similarly, the lower gasket can be detachably connected to the lower limiting column.

[0009] The upper limiting groove and the lower limiting groove further fix the upper gasket and the lower gasket.

[0010] The upper limiting column, the fixed frame body and the lower limiting column are hollow in the middle and form a channel through which the anastomat nail seat sliding rod is completely inserted. The upper limiting column can be inserted into the lower end of the anastomat nail seat to be buckled, so that the upper gasket limited in the upper limiting groove is attached to the lower end surface of the anastomat nail seat. The lower limiting column can be inserted into the upper end of the anastomat nail cartridge to be buckled, so that the lower gasket limited in the lower limiting groove is attached to the upper end surface of the anastomat nail cartridge.

[0011] The upper gasket and the lower gasket are provided with gasket fixing films on the sides away from the fixed frame body, so as to be respectively attached to the lower end surface of the anastomat nail seat and the upper end surface of the anastomat nail cartridge.

[0012] The fixed frame body is a cylinder. Correspondingly, the upper gasket and the lower gasket are circular rings, and the upper limiting column and the lower limiting column are hollow cylinders.

[0013] The advantages of the present application are that the anastomat gasket fixing device can pre-fix the upper gasket and the lower gasket, and when needed, the upper gasket and the lower gasket can be respectively installed on the lower end surface of the anastomat nail seat and the upper end surface of the anastomat nail cartridge through the gasket fixing device, thereby improving the installation efficiency and reducing pollution.

A hollow upper limit post 4 extends from the upper end face of the fixing frame body 3 and a hollow lower limit post 5 extends from the lower end face. The hollow upper limit post 4, the fixing frame body 3 and the lower limit post 5 are connected to form a channel 6 for the complete insertion of the stapler anvil 10 slide rod.

[0035] The side wall surface of the fixed frame body 3 extends to the upper end surface and the lower end surface respectively by a certain height, forms the upper limiting groove 7 containing the upper gasket 1 with the upper limiting column 4, and forms the lower limiting groove 8 containing the lower gasket 2 with the lower limiting column 5; the circular ring-shaped upper gasket 1 is sleeved on the upper limiting column 4 and is limited in the upper limiting groove 7; the cross-sectional diameter of the upper limiting column 4 is greater than the inner diameter of the upper gasket 1, and the cross-sectional diameter of the lower limiting column 5 is greater than the inner diameter of the lower gasket 2. The circular ring-shaped lower gasket 2 is sleeved on the lower limiting column 5 and is limited in the lower limiting groove 8; the upper gasket 1 and the lower gasket 2 are provided with a gasket fixing film 9 on the other side surface in contact with the fixed frame body 3;

[0036] The upper limiting column 4 and the lower limiting column 5 are provided with a certain height, so that the upper limiting column 4 can be inserted into the anastomat nail seat 10 to be buckled, the lower limiting column 5 can be inserted into the anastomat nail cartridge 11 to be buckled, the upper gasket 1 can be just fitted on the lower end surface of the anastomat nail seat 10, and the lower gasket 2 can be just fitted on the upper end surface of the anastomat nail cartridge 11.
