Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a fine-adjustable sample clamping head and a freezing microtome having the same. Background Art

[0002] Frozen sectioning is a technical method that uses physical cooling to freeze fresh tissue specimens to make them have a certain hardness for slicing. Since dehydration and embedding are not required, the preparation speed is faster than paraffin sectioning. It is a good method to provide pathological diagnosis for clinical physicians during surgery. In addition, since the specimens of frozen sections are fresh tissues that have not been fixed, frozen sections are also ideal for fat staining, enzyme histochemical staining, certain immunohistochemical staining and in situ molecular hybridization. Most slicers first put the biological tissue into the freezer to freeze it, and then take it out and put it into the slicer for slicing.

[0003] The existing cryostat sample clamping head is not adjustable, and the thickness of the specimen cutting cannot be adjusted according to actual needs. It cannot meet daily usage requirements and cannot be adjusted according to actual needs. It has low practicality. Therefore, we propose a new type of fine-tunable sample clamping head and a cryostat with the same. Utility Model Content

[0004] Based on the above description, the utility model provides a finely adjustable sample clamping head to solve the problems raised in the background technology.

[0007] The extension mechanism comprises an extension rod, a guide column is fixedly installed on the right side of the extension rod, and a push block is fixedly installed on the upper side of the extension rod.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, the specimen clamp is fixedly mounted on an end of the extension rod away from the mounting piece.

[0014] Furthermore, the internal threads of the mounting member are connected with mounting screws, wherein the number of the mounting screws is two.
