[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3The utility model provides a technical solution: an oral mucosal tissue biopsy sampling forceps, comprising a main body 1, the main body 1 is a rod-shaped structure, one end of the main body 1 is provided with a groove 2, the groove 2 is a long strip, the inside of the groove 2 is hinged with a sampling forceps 3, the sampling forceps 3 are cross-arranged inside the groove 2, the main body 1 is movably provided with a movable block 4, the movable block 4 is cylindrical, and the movable block 4 is coaxially arranged with the main body 1, the movable block 4 is close to the end surface of the sampling forceps 3 provided with a connecting plate 5, the number of the connecting plates 5 is two, and the two connecting plates 5 are symmetrically arranged, a connecting rod 6 is movably provided between the connecting plates 5, the number of the connecting rods 6 is two, and the two connecting rods 6 are respectively movably connected to one end of the sampling forceps 3 corresponding to the inside of the groove 2, such as Figure 1 As shown, when the movable block 4 is controlled to slide inside the main body 1, the connecting rod 6 drives the sampling clamp 3 to rotate, thereby realizing the opening and closing of the sampling clamp 3 and realizing the sampling function.

[0018] Specifically, the main body 1 includes two hinged rods, which are fixed to each other by fixing bolts, so that the main body 1 can rotate to adjust the bending state of the equipment to adapt to sampling operations in different parts.

[0019] Specifically, a movable groove 7 is provided on the surface of one end of the movable block 4 away from the sampling clamp 3. The movable groove 7 is cylindrical and coaxially arranged with the movable block 4. A transmission block 8 is movably provided on the inner surface of the movable groove 7. A transmission groove 9 is provided on the outer circumferential surface of the transmission block 8. The transmission groove 9 is arc-shaped. A protrusion 10 slidably connected to the transmission groove 9 is fixedly connected to the inner circumferential surface of the movable groove 7. A knob 11 is rotatably provided on the end of the main body 1 away from the sampling clamp 3. A rotating rod is provided between the knob 11 and the transmission block 8. By rotating the knob 11, the knob 11 drives the transmission block 8 to rotate through the rotating rod. Under the action of the protrusion and the transmission groove 9, the movable block 4 can be controlled to slide inside the main body 1 to drive the sampling clamp 3 to open and close through the connecting rod 6.

[0020] Specifically, the rotating rod includes two connecting rods 12, and a flexible rod 13 is fixedly connected between the connecting rods 12. The flexible rod 13 is located at the junction of the two rods.

The limiting groove 14 extends in the same direction as the sliding direction of the movable block 4. When the movable block 4 slides inside the main body 1, the limiting block 15 slides synchronously inside the limiting groove 14 to prevent the movable block 4 from rotating with the rotation of the transmission block 8.

[0022] When the utility model is used, the knob 11 is rotated, and the knob 11 drives the connecting rod 12 to rotate. Under the action of the flexible rod 13, the two connecting rods 12 can rotate synchronously, driving the transmission block 8 to rotate. Under the action of the transmission groove 9 and the protrusion, the movable block 4 is driven to slide inside the main body 1. The movable block 4 drives the sampling clamp 3 to open and close through the connecting rod 6 to achieve sampling.
