Working principle: when the biopsy instrument for pathological research is used, firstly, after the living tissue 1 is cut and processed, the living tissue 1 falls to the stomach wall of the patient, and then the housing 2 is inserted into the patient's body. In the body and as shown in Figure 1, at this time, the end of the fixed block 6 away from the pull block 14 is not in contact with the stomach wall in the patient's body, thereby reducing the friction caused by the fixed block 6 to the stomach wall in the patient's body when it rotates;

Then keep the position of the housing 2, and by pulling up the pull block 14 and through the pull rod 13, drive the two support plates 5 to move up, move up through the two support plates 5, drive the two connecting plates 4 to move up, pass through the two The connecting plate 4 moves up and through the hinge relationship between the connecting plate 4 and the rotating arm 3, the two rotating arms 3 are driven to rotate with the hinge point between them and the housing 2 as the center of the circle, and the two rotating arms 3 rotate , to drive the two fixed blocks 6 to rotate, through which the ends of the two fixed blocks 6 away from the pull block 14 rotate in the opposite direction, and then provide clamping force to the living tissue 1;

In the above process, the two supporting plates 5 are moved up and restricted by the rotation of the rotating arm 3, which drives the two connecting plates 4 to move in the opposite direction, and the two connecting plates 4 move in the opposite direction, so that the rope 11 pulls the reel 10 rotates, through the rotation of the winding wheel 10, the rope two 12 is released and the elastic restoring force of the spring one 9 is used, so that the clamp block 7 moves away from the winding wheel 10 while following the rotation of the fixed block 6 and reaches the In the state shown in Figure 5, the living tissue 1 can be clamped at this moment. In the present invention, the clamp block 7 can move toward the stomach wall in the patient's body while following the rotation of the fixed block 6, so that the fixed block 6 and the clamp block 7 are both Without causing friction to the stomach wall in the patient's body, the clamping block 7 can be moved to ensure that the clamping path of the clamping block 7 can be smoothly clamped to the living tissue 1 located on the stomach wall in the patient's body. , when sampling through scissor-like biopsy forceps, in order to ensure that the living tissue 1 located on the stomach wall of the patient can be within the clamping path of the two clamps of the biopsy forceps, it is usually necessary to abut the two clamps of the biopsy forceps into the patient's body The stomach wall can be sampled smoothly, and the invention reduces the friction caused to the stomach wall of the patient;

By continuing to pull up the pull block 14, the two fixed blocks 6 are driven to continue to rotate and pass through the state shown in FIG. 6, and finally to the state shown in FIG. The living tissue 1 is pushed toward the sampling needle 16, and is punctured and fixed by the sampling needle 16. At the same time, when the living tissue 1 is punctured by the sampling needle 16, the two connecting plates 4 move in opposite directions, and the movement of the living tissue 1 The trajectory is limited and squeezed, and then compared with the prior art, when the living tissue 1 is directly pushed, due to the softness of the living tissue 1 itself, it is easy to cause the center of the living tissue 1 to be difficult to be completely punctured by the sampling needle 16 , resulting in the living tissue 1 pierced by the sampling needle 16, the tightness between the living tissue 1 and the sampling needle 16 is not good, and then the phenomenon that the living tissue 1 slips out of the sampling needle 16 occurs;

After moving to the state shown in Figure 7, by slowly moving down the pull block 14 and using the elastic restoring force of the second spring 15, each mechanism is driven to operate in reverse and to the state shown in Figure 9. part has been exposed, and then it is convenient for the needle tip of the sampling needle 16 to puncture the next living tissue 1. At the same time, by pulling the pull block 14 again and repeating the above-mentioned movement, the living tissue 1 can be strung on the sampling needle 16 one by one, so that it can be inserted into the housing. 2 After entering the human body once, multiple sampling can be completed, reducing the sampling time and indirectly reducing the pain of the patient;

After multiple samplings are completed, the casing 2 is removed from the human body, and the living tissue 1 is transferred to an optical microscope for observation.
