Plate coordinates, and forms the accommodation space of all round closure.
In the present embodiment, the concrete structure of the animal spinal fixing device is described.For clearer embodiment, this is moved
Other features of thing spinal fixing device, below by example 2 to embodiment 1 in be further described.
Embodiment 2
First-selection chooses adult fluorescent transgenic mouse, and conventional animal is injected by fluorescer certainly can also realize that fluorescence is seen
Examine.
According to the body weight of mouse, by the yellow Jackets of intraperitoneal injection 10mg/mL, every gram of body weight injection 0.08mg of mouse
Yellow Jackets and erythromycin spongaion.
After by mouse anesthesia, mouse is transferred to carries out the shaving treatment of corresponding site away from field of operation, and uses 70% wine
The row that progresses greatly is cleaned, and is then applied to corresponding shaving area with appropriate depilatory cream, uses scraper plate suitable after 3-5min is waited after smearing uniformly
To strike off depilatory cream and mouse hair.Light the wiping away of physiological saline is dipped with cotton balls and remove remaining hair remover and mouse hair, so repeatedly until clear
Wash clean, finally dries skin with cotton balls.
Mouse is transferred to field of operation, and covers 3 layers and cut hole gauze.
With scalpel in mouse dorsal part midsection skin, otch is 2-2.5cm.With operating forceps blunt separation skin and flesh
Manadesma between meat tissue.
After finding Section four to Section six transverse process, Section four and the 5th are corresponded to curved formula eye scissors and tweezers detachment side
Save the whole of transverse process, the musculature and tendon of Section six transverse process first half, exposure transverse process；With sharp tweezer at Section four and Section six
It is close to the aperture of vertebra blunt separation two in the position of horizontal figure.It should be noted that the device of the present embodiment can be used for first segment to
Any sections of six section transverse process, observation corresponds to second section to the 5th DRGs of section and/or spinal cord dorsal part and side successively
Face axle/dendron, can select different segment to be performed the operation according to different purposes.
Bounced back after the musculature detachment of backbone side, correspond to four horizontal strokes with four teeth of the first fixture and the second fixture respectively
Prominent position insertion musculature, clamps the first fixture and the second fixture and screws down.Pay special attention to：Avoid the first fixture and
The gear shaping of the second fixture penetrates back of the body peritonaeum.
Mouse is transferred on trestle, the tail end of the first fixture is clamped.Two pressure tongues of plate are corresponded into the first fixture
Two the first gear shapings, be inserted to its inner surface, push plate tail end, strut skin and musculature fully expose surgical field of view.
Remaining muscle etc. is further removed with curved scissors and tweezers to organize, controlled bleeding and wiped off with cotton balls to be attached on vertebra
Tissue, fully exposure Section of five transverse process under DRG (i.e. DRGs).Note：Avoid damage to be covered in the hard ridge on DRG
Film.
Section of five transverse process is abraded with bradawl, and vertebral plate wear down around DRG is polished slightly grand for bone plane to DRG.Use cotton
Field of operation is dried in ball hemostasis.Note：Removing process needs slowly soft, it is to avoid firmly excessive worn out vertebral plate.
Appropriate Kwik-Sil biogums are injected in DRG areas, gas bubbles left has been careful not to.
Closing DRG exposed regions directly are covered with cover glass after injection, soft extruding causes that biogum enters accommodation space
Other parts.
General 10-20min biogums are waited to fix.
U-shaped plate is placed on the first gear shaping top of the first fixture, and the two is bonded with a small amount of superglue.
It is coated in appropriate dental basse acrylic resin liquid acrylic acid and square groove is formed around U-shaped plate, and other spaces are filled with it, it is to avoid imaging
When the extravasation of square groove reclaimed water.
After about 3-5min, dental basse acrylic resin liquid propylene acid hardening, you can cut the Handheld Division of plate afterbody.
The device edge of skin edge and the present embodiment is applied to dental basse acrylic resin liquid acrylic acid, and accommodation space is filled with it,
Good closing observation ward is provided.
By the operating method of the present embodiment, it is capable of achieving the fixation of the present embodiment device, and is studied for spinal cord axons,
The spinal cord axons of animal dorsal part can be observed.
The above, is only presently preferred embodiments of the present invention, and any formal limitation is not made to the present invention, is appointed
What those skilled in the art, without departing from the scope of the present invention, when in the technology using the disclosure above
Appearance is made a little change or is modified to the Equivalent embodiments of equivalent variations, as long as being the content without departing from technical solution of the present invention,
Any simple modification, equivalent variations and the modification made to above example according to technical spirit of the invention, still fall within this
In the range of inventive technique scheme.
