The utility model discloses a grinding head and with grinding head matched with grinding recess, carry out hammering and grinding to hard tissue in grinding the recess through the grinding head, biological tissue slides to grinding the recess along the recess wall in the grinding process for the grinding of tissue is more abundant.
Description
Technical Field
The utility model relates to a biology experiment equipment technical field, concretely relates to be used for grinding hard tissue mill.
Background
Currently, many studies involve the extraction of tissue nucleic acids and proteins. Whether the tissue can be fully ground under the conditions of low temperature and no pollution, and the tissue quantity is kept to the maximum extent, is an important link for successfully extracting nucleic acid and protein. Through the traditional method, nucleic acid and protein in soft tissues can be easily extracted, but when the soft tissues meet hard tissues such as bones or cartilages, the tissues can become very hard after low-temperature freezing, the hard tissues are difficult to grind without other devices, and the existing mortar has large opening and small grinding rod, so that the tissues are easy to splash in the grinding process, part of tissue materials are lost, the retention rate is low, and the detection effect is influenced. And the extraction efficiency of nucleic acid and protein is low, and after other experimental devices are used, the biological activity is low, and the extraction efficiency is low.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a mill for grinding hard tissue, it can overcome the aforesaid because hard tissue extraction efficiency is low, easily splashes, and the retention rate is low, the lower defect of biological activity of extraction.
To achieve the above object, the solution of the present invention is:
the utility model provides a mill for grinding hard tissue, includes mill base and grinding piece, the grinding piece adopts resistant liquid nitrogen low temperature ceramic material, just the grinding piece lower extreme is provided with the grinding head that is used for the grinding, be equipped with on the mill base with grinding head matched with grinds the recess, the grinding head carries out the hammering to the hard tissue of treating the grinding in the grinding recess and grinds.
Further, the grinding head is shaped as a sphere or a hemisphere.
Furthermore, the upper part of the grinding part is provided with a wavy grab handle which is beneficial to holding and hammering.
Furthermore, a group of grinding grooves are uniformly distributed on the base of the grinder, and the inner surfaces of the grinding grooves are smooth surfaces, so that the ground tissues can be extracted.
Further, the outer surface of the grinding head adopts a smooth surface.
After adopting above-mentioned technical scheme, when implementing, carry out hammering, grind the nucleic acid and the protein that are used for extracting soft tissue or hard tissue through the grinding head in grinding the recess inside, and grind more abundant, easy operation saves time, and the retention rate is high, can make biological activity keep better.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a partial cross-sectional view of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the utility model discloses a grinder for grinding hard tissue, including a grinder base 1 and the grinding member 2 that is used for grinding, this grinding member adopts the grinding post, wherein, the grinding member 2 lower extreme is equipped with the grinding head 21 that is used for grinding and hammering, grinder base 1 has seted up a plurality of and grinding head 21 matched with grinding groove. In the grinding process, the grinding head 21 is hammered, rotated and extruded in the grinding groove 11, and the grinding piece 2 moves up and down to enable tissues to slide into the grinding groove 11 along the groove wall, so that the tissues are ground more fully. Wherein, the grinding piece 2 is made of a liquid nitrogen resistant low-temperature ceramic material; by adopting the structure of the liquid nitrogen-resistant low-temperature ceramic material, the biological tissue sample becomes fragile and easy to process, the biological activity can be better protected, and the probability of extracting nucleic acid and protein is higher.
Specifically, the lower end of the grinding column is set to be spherical or hemispherical, in this embodiment, as shown in fig. 2, the grinding column is hemispherical, and the hemispherical grinding column can better grind the soft tissue and the hard tissue in the grinder, and the soft tissue and the hard tissue are not easy to be carried away from the groove 11 along with the hemispherical grinding column.
Grind 2 upper ends and be equipped with the grab handle 22 that does benefit to the assurance, this grab handle 22 adopts the wave, when carrying out the hammering, can will grind that the post is held tighter, is difficult for dropping, and grinds more conveniently, more carefully.
The surfaces of the grinding groove 11 and the grinding head 21 are smooth surfaces, so that the grinding head 21 and the grinding groove 11 can grind biological tissues more finely, the efficiency of extracting nucleic acid and protein is increased more, and the biological tissues attached to the grinding groove 11 and the grinding head 21 are fewer, so that the survival rate of the biological tissues in the grinder is high, and the detection is more accurate.
When the utility model is used, the operation is as follows:
1. cleaning equipment such as a grinder base 1, a grinding column and the like;
2. putting a sample to be processed into the grinding groove 11, adding liquid nitrogen, and slowly flowing in at a low flow rate;
3. the grinding head 21 is closely contacted with the bottom of the grinding groove 11, and is used for hammering and grinding forcibly to grind hard tissues or soft tissues into powder;
4. after the grinding into powder, the soft or hard tissue in the grinding groove 11 is rapidly taken out for use.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
