technical field

The invention relates to a medical device, in particular to an anti-curling tweezers for pathological sections and an operation method thereof.

Background technique

During the pathological tissue slicing process, when the blade starts to cut the pathological tissue, the thin layer of tissue will naturally form a curl. Despite the existence of the anti-curling baffle, the pathological thin-layer tissue still inevitably curls. After curling, the position often shifts, resulting in the result of the slice not being very continuous with the upper slice, so that some important information is missed. , bringing unnecessary troubles to the experimenter. Experimenters often use soft materials such as brushes to flatten this curl. However, during the breaking process, due to the instability of the operator, it is easy to tear up the cut tissue. At the same time, because these materials themselves Adhesion is not sufficient, resulting in detachment and re-curling when the patch is prepared after manipulation. Some anti-slice curling devices, but unavoidable manual operation halfway.

As introduced in the background technology, in the prior art, experimenters often use soft materials such as brushes to break off the curls. However, in the process of breaking off, because the operator is unstable, it is easy to break the curls that have been cut. The tissue shreds, and at the same time, the material itself is not sufficiently adhesive, causing it to fall off and recurl in preparation for the patch after the operation. Some anti-slice curling devices, but unavoidable manual operation in the middle, in order to solve the above technical problems, this application proposes

In a typical implementation of the present application, as shown in Figure 1, a kind of anti-curling tweezers for pathological sections is provided, including a tweezer handle 11, an air cavity 3 is provided inside the tweezer handle 11, and the tweezer handle 11 One end of the tweezers is provided with a cavity 10, and a micro blower 2 is installed in the cavity, and the cavity is provided with an air outlet 9; the other end of the tweezers handle is connected to two tweezers legs 12; in the two tweezers legs The inside of 12 is provided with an air cavity 4 communicating with the air cavity 3, and an air inlet 6 communicating with the air cavity 4 is provided on one of the tweezers legs 12, and a tweezers ball 7 is respectively installed on the heads of the two tweezers legs; The surface of the tweezers ball 7 is covered with air inlet holes II communicating with the air cavity 4; the blower 2 is controlled by a control device.

Further, a screw cap is provided beside the air inlet 6, and the rotation of the screw cap is controlled by a control button, so as to realize the closing or opening of the air inlet 6.
