Abstract
A vibration type slicer applied to tissue culture relates to a medical mechanical device, especially a slicer for biomedical tissue culture, which is composed of a base, a vibration arm, a knife rack, a knife blade, a sample platform, a vibration system and a step-by-step system, the vibration arm is mounted on the base by the vibration system, the knife rack is mounted on the vibration arm, the knife blade is mounted on the knife rack, the sample platform is mounted on the step-by-step system and is positioned rightly under the vibration arm; the vibration system is composed of an electric machine and drive gears, the step-by-step system is composed of an electric control translational platform and a step-by-step electric machine controller, a damping spring is mounted between the vibration arm and the knife rack. The slicer overcomes the problem of mechanical cutting generation amplification, can be applied to amplification cultivation of tissue slice, the damping spring can enable the slicing force to be more even and can protect the knife blade, the slicer volume is small, the slicer is suitable for ultraviolet ray disinfecting and slicing in the superclean workbench.
Description
Technical field
The utility model relates to a kind of medical machinery equipment, especially a kind of microtome that is used for biomedical tissue cultivation usefulness.
Background technology
Histotomy is widely used in biological and basis and clinical medicine domain, it mainly contains two class histotomies and uses, the one, fixedly the paraffin of embedding and freezing ultra-thin section are that the slice of fresh biological tissue is used for tissue culture to carry out morphology research in addition.Tissue culture is the experimental technique that often is applied in the biological and medical field research, has cellular incubation and piece of tissue to cultivate two kinds.Wherein, the histotome that animal tissue cultivates mainly is that the brain sheet that is applied in the Neuroscience Research is cultivated, though this microtome is powerful, volume is big, complex structure, price are high, and it is designed primarily to the service of cultivating of brain sheet, so range of application is very limited.At present, the human embryo neural stem cells that is used for the treatment of multiple sacred disease only can be with the machine cuts amplification of going down to posterity, and traditional histotome is difficult to use in this technology.Therefore need to improve existing microtome technology, can be applied to the amplification cultivation of histotomy.
Summary of the invention
Technical problem to be solved in the utility model is that present microtome does not fit into and organizes amplification cultivation, and a kind of cheap oscillatory type tissue culture microtome is provided.
The utility model is made of support, shaker arm, knife rest, blade, sample stage, vibrational system and step-by-step system, shaker arm is installed on the support by vibrational system, and knife rest is installed on the shaker arm, and blade is installed on the knife rest, sample stage is installed on the step-by-step system, is positioned under the shaker arm; Vibrational system is made of motor and transmission gear, and step-by-step system is made of electronic control translation stage and controllor for step-by-step motor, it is characterized in that having installed between shaker arm and the knife rest damping spring.
Wherein cutter frame structure is to pass plastic tube by an iron wire, and iron wire one end is provided with snap ring and is stuck on the plastic tube, and the other end is connected with nut clip, the middle damping spring of installing.
Because iron wire can slide in plastic tube, sliding scale is subjected to the restriction of damping spring and the terminal snap ring of iron wire, can be because of blade distortion or slide are broken in the process of cutting.
This microtome has overcome the drawback that machine cuts goes down to posterity and increases; can be applied to the amplification cultivation of histotomy; with respect to traditional vibratome, shaker arm contains a damping spring can make the dynamics of section more even, and can play the effect of protection blade.Blade fastens with two nut clip, and platform is adjusted its tangent plane per sample.Microtome volume of the present utility model is little, is applicable in superclean bench to help guaranteeing the aseptic condition of tissue culture with disinfection by ultraviolet light and section.
