description of the reference symbols

The clamp comprises a core bar 1, a clamp head component 2, a sliding ring 3, a stay cable 4, an elastic outer tube 5, a waist-shaped hole 6, a connecting rod 7, a screw hole I8, a fixing block 9, a screw hole II 10, a pull ring 11, a screw hole IV 12, a telescopic return rod 13, an outer tube 14, an inner rod 15, a return spring 16 and a screw hole III 17.

Detailed Description

The present invention will be described in further detail with reference to examples.

The embodiment provides a rectum biopsy forceps for urinary anorectal department, which comprises a core bar 1, a forceps head assembly 2 and a slip ring 3 in sliding connection with the core bar 1, and the outer wall of the slip ring 3 is a frosted surface so as to improve the texture of the forceps, as shown in fig. 1 to 4. The binding clip assembly 2 is connected with a pull rope 4, a waist-shaped hole 6 arranged along the length direction is formed in the core rod 1, and a pull ring 11 is arranged at one end, far away from the binding clip assembly 2, of the core rod 1. A spring outer tube 5 is connected between the tong head assembly 2 and the core bar 1, one end of the stay cable 4 is connected with the tong head assembly 2, and the other end of the stay cable penetrates through the spring outer tube 5, penetrates through the core bar 1, finally enters the kidney-shaped hole 6 and is connected with the slip ring 3; the connecting rod 7 located in the waist-shaped hole 6 is connected in the sliding ring 3, a first screw hole 8 is formed in one end, far away from the sliding ring 3, of the connecting rod 7, a fixing block 9 is arranged on the core rod 1, a groove communicated with the waist-shaped hole 6 is formed in the fixing block 9, a second screw hole 10 is formed in the groove, and a fastening screw used for being connected with the first screw hole 8 is arranged in the second screw hole 10.

The connection of the connecting rod 7 to the slip ring 3 is as follows: the end, far away from the first screw hole 8, of the connecting rod 7 is provided with a third screw hole 17, the side wall of the sliding ring 3 is provided with a fourth screw hole 12, and a connecting screw used for being connected with the third screw hole 17 is connected into the fourth screw hole 12.

In order to enable the tong head assembly 2 to be automatically closed, a telescopic return rod 13 is arranged between the sliding ring 3 and the fixing block 9, the telescopic return rod 13 comprises an outer tube 14 connected with the fixing block 9, an inner rod 15 connected with the sliding ring 3 is arranged in the outer tube 14, and a return spring 16 is connected between the outer tube 14 and the inner rod 15.
