Description
Technical field
The invention belongs to armarium technical field, be specifically related to the non-cranium of a kind of large mice and bore skull boring device.
Background technology
The operation of opening cranium of large and small Mus is necessity operation of the administration of experimental mouse intracranial and Electrophysiology experimental record.Traditional electronic cranium bores opens the not only very difficult size that regulates the skull aperture of opening of cranium method, and the uncontrollable electric drill degree of depth, easily causes intracranial infection and brain tissue impairment; Electric drill can, to a Mus random concussion, cause the neurocyte of Mus intracranial and nerve fiber inevitably to be damaged, thereby affect the brain function of experimental mouse simultaneously, has strengthened the mortality rate of Mus, very unfavorable to experimental result.
Summary of the invention
The present invention has out the difficult adjusting in cranium aperture, the uncontrollable degree of depth, easy damaged cerebral tissue mainly for the operation of opening cranium that adopts conventional electric cranium to creep into the large mice of row, when cranium left by electric drill, cause cerebral concussion, affect the problems such as experimental result, provide a kind of simple, effectively, Wicresoft, aperture is controlled, the degree of depth is adjustable non-cranium bore skull boring device, to reduce the damage of experimental mouse brain, thereby meet the needs of intracranial administration and Electrophysiology record.
The present invention addresses the above problem the technical scheme of taking to be:
The non-cranium of a kind of large mice bores skull boring device, comprise hands handle, wherein: also comprise fixed cover, adjusting nut, protective sleeve, needle body connecting portion, needle body connects lobe, fixed bar, threaded rod and needle body, described needle body connecting portion is located at the lower end of handle, needle body connection lobe is located at the lower end of needle body connecting portion, the upper end of fixed bar is connected lobe with needle body and is connected, the lower end of fixed bar is connected with the upper end of threaded rod, the lower end of threaded rod is connected with needle body, fixed cover is enclosed within on needle body connecting portion, adjusting nut and protective sleeve are all located on threaded rod and adjusting nut is positioned at the top of protective sleeve.
The needle point of described needle body lower end be shaped as the taper of concave surface Rhizoma Sparganii.
The outer surface of described handle is provided with striped.
The present invention adopts technique scheme, fixed bar and needle body are connected employing between lobe and are flexibly connected, and the needle body being connected from fixed bar has different specifications, so just can select applicable needle body according to concrete requirement of experiment, and then control the pore size of perforate; Protective sleeve can effectively be controlled the skull perforate degree of depth, avoids crossing the dark damage to cerebral tissue because of perforate; Needle point is the taper of concave surface Rhizoma Sparganii, and light ground auger is opened skull fast, reduces experimental mouse cerebral hemorrhage and cerebral concussion, and then guarantees the accuracy of experimental result.Therefore, compared with prior art, the present invention has the following advantages: that 1, can select different size opens cranium pin, thereby controls the size of opening cranium aperture; 2, can accurately regulate the height of protective sleeve, control the degree of depth of skull perforate, while avoiding out cranium, cross dark injured brain tissue; 3, Wicresoft manually opens cranium operation, reduces Mus cerebral concussion and wound surface damage, accelerating wound healing; 4, install simple to operation, improve operation efficiency; 5, device is light and handy, and portable, cost is low.

The specific embodiment
As shown in Figures 1 to 5, the non-cranium of a kind of large mice bores skull boring device, comprise handle 1, wherein: also comprise fixed cover 2, adjusting nut 3, protective sleeve 4, needle body connecting portion 5, needle body connects lobe 10, fixed bar 6, threaded rod 7 and needle body 8, be provided with nicking 11 at the outer surface of handle 1, described needle body connecting portion 5 is located at the lower end of handle 1, needle body connection lobe 10 is located at the lower end of needle body connecting portion 5, the upper end of fixed bar 6 is inserted needle body and is connected in lobe 10, the lower end of fixed bar 6 is connected with the upper end of threaded rod 7, the lower end of threaded rod 7 is connected with needle body 8, the needle point 9 of needle body 8 lower ends is the taper of concave surface Rhizoma Sparganii, fixed cover 2 is enclosed within on needle body connecting portion 5, adjusting nut 3 and protective sleeve 4 are all located on threaded rod 7 and adjusting nut 3 is positioned at the top of protective sleeve 4.
Concrete operation step is as follows:
The first step: experimental needs, determine the pore size of required skull perforate, and select the needle body of respective model;
Second step: the fixed bar of needle body is inserted to needle body and connect in lobe, and with fixed cover, it is spiral fixing;
The 3rd step: regulate adjusting nut and the position of protective sleeve on threaded rod, thereby determine needle body open the cranium degree of depth;
The 4th step: by rotary handle, open cranium to anaesthetizing fixing large mice.
Below by specific experiment, invention is described in detail technical scheme of the present invention in order further to explain.
For example wish is by the cranium of opening before SD rat (body weight 250g) intracranial hippocampal injection administration.Because the diameter of administration needle is 0.38mm, the diameter 0.5mm of required skull perforate is advisable, and is that to be 0.3mm open cranium pin for 0.5mm, needle point height therefore can select needle body diameter.The needle body that the fixed bar of opening cranium pin is inserted to handle connects in lobe, and with fixed cover, it is spiral fixing.Install and regulate adjusting nut and protective sleeve; opening cranium because of this not only needs brill to open skull; also need to puncture cerebral dura mater; to enter smoothly administration with administration needle; rule of thumb, the relative distance of protective sleeve and needle point is adjusted to about 1.2mm left and right, passes through rotary handle; in the relevant position of anaesthetizing fixing rat skull, (3.0mm after Bregma, the other 2.2mm that opens of center line) opens cranium.
