Description

Bone grinder

Technical field

The utility model relates to forensic medical examination field more particularly to a kind of bone grinders for legal medical expert's detection field.

Background technique

In legal medical expert's detection field, DNA examines the routine techniques for having become individual identification identification.The sample extracted at the scene In, bone can effectively protect osteocyte since its institutional framework has resistance to corruptibility, can preferably resist external environment influence. After other samples are completely corrupt, bone still is able to the important materials examined as DNA.Therefore, it is extracted from bone DNA simultaneously carries out STR parting to examine being the important technical for carrying out height corruption and the corpse decomposed to bony skeleton identification of corpse.

But for the time too long, for the poor Old Bones of Conservation environment, due in bone tissue DNA content it is few and Degree of degradation is high, and DNA extracts relative difficulty.For improve bone in DNA recall rate, after bone class sample is handled before completion, It needs to crush on bone for bone meal to improve osteocyte lysis efficiency, as much as possible releases the DNA in osteocyte.

Currently, the common instrument for bone to crush is that electronic bone crusher is difficult since it is expensive in legal medical expert It popularizes in an all-round way in field.Therefore, there is an urgent need to develop a kind of economical and practical bone grinders.

Utility model content

The utility model provides a kind of economical and practical bone grinder for legal medical expert's detection field.The bone powder Millstone includes pedestal, shell, hand basket and crushes stick, and wherein hand basket is taken with the bottom groove for holding bone and conveniently Hangers, and shell has the inboard wall groove to match with hand basket hangers, it is ensured that hand basket can be fixed in bone crushing process Without movement in shell.Crushing stick has the top bump to match with hand basket bottom groove, crushes under external force The bone held in hand basket bottom groove, while guaranteeing that bone meal is all held in hand basket bottom groove without splashes, Bone only need to clean hand basket after crushing, and avoid different sample cross contaminations.

In an embodiment of the utility model, pedestal with shell be it is integrally formed, improve the whole of grinder Body intensity.In another embodiment, reinforcement connector is provided between pedestal and shell, further stabilizing bone crushes Device, it is ensured that it will not occur mobile in bone crushing process or be tilted because of external force.

The bone grinder delicate structure, easy to operate, economy and durability of the utility model, are suitble to big in legal medical expert's detection field Range is promoted the use of.

Specific embodiment

In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with attached drawing pair The utility model is further detailed.

As shown in Figure 1, the chassis 1 of the bone grinder of the utility model and shell 2 are integrally formed, and on chassis Multiple reinforcement connectors 1.1 are provided between 1 and shell 2, the chassis being designed in this way and shell mechanism are stablized, under external force Bone crushing process in will not occur mobile or tilt it is not necessary that experimenter is hand steered.In practice, bone grinder is usually Bone crushing is carried out under condition of ultralow temperature, in order to avoid frostbite, cannot directly contact bone crushing with hand in the process The shell of device.And the above-mentioned design of the utility model ensure that experiment safety while ultralow temperature crushes bone.

As shown in Fig. 2, the hand basket 3 of the bone grinder of the utility model includes the bottom groove 3.1 for holding bone And the hangers 3.2 conveniently taken.In conjunction with Fig. 1, when hand basket 3 is put into shell 2, hand basket hangers 3.2 is just placed in the interior of shell 2 In wall groove 2.1, it is ensured that hand basket 3 is fixed in shell without movement in the bone crushing process under external force.

As shown in figure 3, the crushing stick 4 of the bone grinder of the utility model has top bump 4.1, and shown in Fig. 2 Hand basket bottom groove 3.1 match.When external force is when crushing stick, it is recessed that crushing stick top bump 4.1 crushes hand basket bottom The bone held in slot 3.1, while guaranteeing that the bone meal formed after bone crushing is held in hand basket bottom groove without four Place splashes, and bone only need to clean hand basket after crushing, and avoids different sample cross contaminations.

As shown in figure 4, the bone grinder of the utility model delicate structure, easy to operate on the whole.Compared to electrical bone Bone crusher is more economically durable, is suitble to promote the use of on a large scale in legal medical expert's detection field.

It is above that certain exemplary embodiments of the utility model, the common skill of this field are only described by way of explanation Art personnel, can be with a variety of different modes to described reality without departing from the spirit and scope of the utility model Example is applied to be adjusted.
