The sliding grooves 303 in the long seat base 1 are slightly larger, and the inner fixing plate 305 and the inner sealing gasket 306 can be completely stored inside. When the long seat base 1 and the long seat shell 2 are combined, the internal fixing plate 305 and the inner sealing gasket 306 are driven to rotate to the connection between the long seat base 1 and the long seat shell 2 through the external rotating shell 301 and the connecting bracket 304, so as to seal the connection. The connection of the rotating shell 301 is provided with a sealing gasket 302 to provide sealing. In this way, the long seat base 1 and the long seat shell 2 can enhance the sealing effect of the connection while ensuring opening and closing.

[0023] Furthermore, the sealing gasket 302 covers the connection between the long seat base 1 and the rotating shell 301, the connecting bracket 304 is rotatably connected to the inner surface of the long seat base 1, and the connection of the rotating shell 301 is provided with a sealing gasket 302 to provide sealing, and the inner fixed plate 305 and the inner sealing gasket 306 are driven to rotate to the connection between the long seat base 1 and the long seat shell 2 through the external rotating shell 301 and the connecting bracket 304.

The connecting rod 404, the partition plate 405, the piston head 406, the one-way valve A407, the one-way valve B408 and the connecting pipe 409 are arranged. During use, the interior of the mounting base 401 is divided into two parts by the partition plate 405, one part is used to move the toggle block 403 and the other part is used to move the piston head 406. In the initial state, the piston head 406 is at the end of the one-way valve. When the long seat and the sealing mechanism 3 are both closed, the toggle block 403 is pulled to pull the piston head 406 out through the connecting rod 404. At this time, suction is generated to extract the internal air. The one-way valve A407 can only output to the outside and does not work at this time. The one-way valve B408 and the connecting pipe 409 can generate suction to the inside of the long seat. If it is difficult to pull out the piston head 406 at this time, it means that the sealing effect is good. When the piston head 406 moves in the opposite direction, a thrust is generated to push the air out only from the one-way valve A407, thereby preventing external air from entering the long seat, thereby extracting the internal air and detecting the seal.

When the detection mechanism 4 is used, the air is extracted from the long seat and pushed out from the mounting base 401.

[0028] Working principle: A long seat for minimally invasive surgical tissue clamps with good sealing performance. During use, the inner sealing gasket 306 is made of rubber, which is soft and has a certain elasticity, but is easy to bend and fold. The back is connected to the inner fixing plate 305 so that it can always be in an arc shape. The long seat base 1 and the long seat shell 2 are both provided with sliding grooves 303 and are connected at the connection point. The sliding grooves 303 in the long seat base 1 are slightly larger, and the inner fixing plate 305 and the inner sealing gasket 306 can be completely stored inside. When the long seat base 1 and the long seat shell 2 are combined, the inner fixing plate 305 and the inner sealing gasket 306 are driven to rotate to the connection point of the long seat base 1 and the long seat shell 2 through the external rotating shell 301 and the connecting bracket 304, so as to seal the connection point. The connection point of the rotating shell 301 is provided with a sealing gasket 302 to provide sealing, so that the long seat base 1 and the long seat shell 2 can be opened and closed. , to enhance the sealing effect at the connection, the interior of the mounting base 401 is divided into two parts by a partition plate 405, one part is used to move the toggle block 403 and the other part is used to move the piston head 406. In the initial state, the piston head 406 is at the end of the one-way valve. When the long seat and the sealing mechanism 3 are closed, the toggle block 403 is pulled out through the connecting rod 404 to pull the piston head 406 out. At this time, suction is generated to extract the internal air, and the one-way valve A407 can only output outward and does not work at this time. The one-way valve B408 and the connecting pipe 409 can generate suction to the inside of the long seat. If it is difficult to pull out the piston head 406 at this time, it means that the sealing effect is good. When the piston head 406 moves in the opposite direction, a thrust is generated to push the air out only from the one-way valve A407, preventing external air from entering the long seat, thereby extracting the internal air and detecting the seal. In this way, a long seat for minimally invasive surgical tissue clamps with good sealing performance is completed.
