The utility model has the advantages of, it has compensatied the not enough of traditional hard tissue slicer, provides a simple structure is reliable, need not manual grinding, deformation when having avoided the section, and is higher to the adsorptivity of section, has increased substantially a hard tissue slicer's of section precision last sucking disc mechanism.

Description

Upper sucker mechanism of hard tissue slicer

Technical Field

The utility model relates to a hard tissue slicer field, concretely relates to last sucking disc mechanism of hard tissue slicer.

Background

Hard tissue microtomes are important instrumentation for performing histomorphological studies. The bone cutting instrument is mainly used for cutting hard tissue specimens (including non-decalcified bone tissues and the like) or fragile materials, the tissues are kept not to deform after cutting, and accurate bone morphometry detection can be guaranteed. Not only can slice and form measurement analysis of the hard tissue specimen be carried out, but also the fluorescence mark can be observed and the picture can be taken; but also can observe the integration condition of the implant (such as metallic titanium, ceramics, bioglass and the like) and the bone interface. Has been widely applied to the research of medical materials science, orthopaedics, stomatology and even cardiovascular stents.

At present, the best level of the same industry in China can be cut to 0.06mm, and a thick slice of 0.10mm is usually adopted and then manually grinded to meet the requirement of pathological research. Moreover, because the hardness difference between the metal material and the plastic embedding material in the specimen is large, the deformation of the specimen often causes the fragmentation, the curling and the deformation in the cutting process, and the slicing failure is caused. The excessive thickness can only be manually ground on a polishing machine, which is easy to cause waste products and wastes time and labor.

The utility model relates to a hard tissue slicer, one-time cutting shaping, not curl, difficult broken, the thinnest 20 microns that can reach at present. The requirement of pathological observation can be met by thick and smooth slices without manual grinding.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above problem, provide a simple structure is reliable, need not manual grinding, deformation when having avoided the section, and is higher to the adsorptivity of section, has increased substantially a hard tissue slicer's of section precision last sucking disc mechanism.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides an upper sucker mechanism of hard tissue slicer, includes that one end is used for adsorbing the sliced upper sucker of sample, the other end of upper sucker has the vacuum source through the pipe connection, be hollow form in the upper sucker.

Further, the specimen slice adsorbed on the upper suction head is obtained by cutting the embedded slice with a diamond cutter.

Furthermore, an upper suction head bracket is arranged on two sides of the upper end of the upper suction head.

Furthermore, a diamond cutter is arranged below the upper suction head.

Further, the width of the hollow upper suction head is matched with that of the vacuum source.

The beneficial effects of the utility model reside in that:

the utility model discloses compensate the not enough of traditional hard tissue slicer, provide a simple structure reliable, need not manual grinding, deformation when having avoided the section, it is higher to the adsorptivity of section, has increased substantially a hard tissue slicer's of section precision last sucking disc mechanism.

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required to be used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only for the purpose of more clearly illustrating the embodiments of the present invention or the technical solutions in the prior art, and for those skilled in the art, other drawings can be obtained according to these drawings without any creative efforts.

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The upper sucker mechanism of the hard tissue microtome shown in fig. 1 comprises an upper sucker 6 with one end used for adsorbing a specimen slice 3, the other end of the upper sucker 6 is connected with a vacuum source 1 through a pipeline, and the interior of the upper sucker 6 is hollow.

Further, the specimen slice 3 adsorbed on the upper tip 6 is obtained by cutting the embedded slice 5 with a diamond cutter 4.

Furthermore, an upper suction head bracket 2 is arranged on two sides of the upper end of the upper suction head 6.

Further, a diamond cutter 4 is arranged below the upper suction head 6.

Further, the width of the hollow upper suction head 6 is matched with the width of the vacuum source 1.

When the mechanism is used for slicing the embedded specimen 5, an upper plane of a position to be obtained is cut out of the embedded specimen 5, and then the expected slice thickness is adjusted; the upper suction head 6 is close to the embedded specimen 5, the specimen slice 3 is adsorbed and fixed in advance through the vacuum air source 1 of the upper suction head 6, the sliced bending deformation can be avoided in the following slicing process, the sliced slice is firmly adsorbed below the upper suction head, and the sliced slice can be easily taken down after the negative pressure switch is turned off.

The device has reasonable design and firm structure; the ultrathin slicing process of the machine greatly improves the slicing precision, and the slice thickness is as thin as 20 microns. The slicing processing can meet the requirements of scientific research personnel on slice thickness, flatness, smoothness and the like at one time.

The present invention is not described in detail in the prior art.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
