The invention discloses a device for cutting a transverse section specimen of a human body, belonging to the technical field of medical instrument devices. At present, a frozen specimen is always cut by using a carpenter saw, a motor-driven band saw machine or a large freezing microtome, but all the devices are complex to transform and are inconvenient to operate. The invention adopts the following technical scheme: the right end of a cutting workbench (1) is provided with a dovetail groove (8); two bolts are respectively fixed on the left end of the cutting workbench (1); a transverse feeding operating floor (16) with a transverse dovetail groove (17) is fixed on a nut dovetail slide block (6); a motor (5) with the dovetail slide block is embedded into the transverse dovetail groove (17); a transverse nut rack (19) is fixed on the transverse feeding operating floor (16); one end of a transverse feeding lead screw (18) screwed in the transverse nut rack (19) is hinged with the motor (5); and the other end of the transverse feeding lead screw (18) is fixedly provided with a rotation wheel (20). The device for cutting a transverse section specimen of a human body has the advantage of high machining precision, and ultra-thin precise cutting for human body specimens can be realized.
Description
technical field [0001] The invention relates to the technical field of medical instruments and devices, in particular to a cutting device for human cross-sectional specimens. Background technique [0002] Using medical imaging technology to cut tomography of human specimens for anatomy can be beneficial to the research and diagnosis of human diseases, such as: internal medicine, surgery and medical imaging and other disciplines. Therefore, making continuous, thin-layer, and representative tomographic specimens is a necessary guarantee for improving tomographic anatomy. At present, the cutting of frozen specimens is generally cut with woodworking saws, electric band saws, or milled with large-scale cryostats and milling machines; these equipments are troublesome to operate and are not very convenient to operate, so a special human body cross-sectional specimen cutting is designed. Machines are a top priority. Contents of the invention [0003] In order to overcome the abo...
