Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Example 1

As shown in fig. 1-2, the present embodiment provides an immunohistochemical contrast precise sampling device, which includes an outer tube 10, a push rod 20 and a handle 30, wherein the outer tube 10 is sleeved outside the push rod 20, and the handle 30 is fixedly disposed at one end of the outer tube 10; the end of the outer tube 10 far away from the handle 30 is provided with saw teeth 11; the inner wall of the outer tube 10 is provided with a pair of protrusions 12, one side of the protrusions 12 close to the handle 30 is clamped with a return spring 40, and the diameter of the return spring 40 is larger than the gap between the protrusions 12; a snap ring 21 is fixedly arranged on the outer wall of the push rod 20, and the outer diameter of the snap ring 21 is attached to the inner wall of the outer tube 10.

When the device is used, one end of the outer tube 10 with the saw teeth 11 is inserted into the wax block, the outer tube 10 is pulled out after pathological change tissues enter the outer tube 10, then the push rod 20 is pressed downwards, the return spring 40 is compressed, the pathological change tissues and the wax block in the outer tube 10 are pushed out by the bottom end of the push rod 20, so that material taking can be completed, after the push rod 20 is pressed, the return spring 40 pushes the snap ring 21 of the push rod 20, so that the push rod 20 is reset, and next material taking is facilitated; use the utility model discloses a material sampler can be accurate draw materials to the pathological change tissue of wax stone central authorities, simple structure, and convenient operation reduces the degree of difficulty of drawing materials, saves experimenter operating time.
