Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a sampling knife with a protective function for clinical pathological diagnosis. Background Art
[0002] Pathological sections are a type of pathological specimen. During the preparation process, some diseased tissues or organs are treated with various chemicals and burying methods to fix and harden them. They are then cut into thin slices on a microtome, adhered to glass slides, and stained with various colors for examination under a microscope to observe pathological changes and make pathological diagnoses, thereby providing assistance for clinical diagnosis and treatment.
[0003] Traditional cutting knives have a simple structure and low safety. When not in use, the knife body cannot be stored, posing a safety hazard. Utility Model Content
[0004] In order to solve the above technical problems, the utility model proposes the following technical solutions:

[0006] Furthermore, the outer wall of the handle is provided with protrusions.
[0007] Furthermore, the pull rod is connected to an outer wall of the groove section with a spring, and the other end of the spring is connected to the groove wall of the groove.
[0008] Furthermore, the card cavity includes a vertically arranged push groove and a card connection groove connected to the push groove, and a plurality of the card connection grooves are provided.
[0009] Furthermore, sterilizing cotton is bonded around the opening at the lower end of the blade housing, and the inner wall of the sterilizing cotton fits and slides with the blade.
[0010] Furthermore, a pressure plate is connected to the top of the knife housing.
[0011] Compared with the prior art, the utility model has the following beneficial effects: when the utility model is used, the push handles arranged at both ends are driven toward the middle to drive the pull rod compression spring, so that the pull rod is flush with the push groove, and the push handle is pushed downward to push the blade out. The blade of the required depth can be pushed out according to the material specifications, and the push handle is released. The pull rod moves toward the end side of the clamping groove under the push of the spring to clamp the blade, thereby fixing the blade; when collecting materials, the convex particles arranged on the outer wall of the knife handle increase friction to prevent the material collecting knife from falling when collecting materials; when using hard materials, the finger can be used to press the pressure plate to apply force; after collecting materials, the blade can be cleaned or wiped, and then the blade can be retracted into the knife shell. During the retraction process, the outer wall of the blade and the disinfection cotton are fitted and slid to wipe and disinfect. BRIEF DESCRIPTION OF THE DRAWINGS
