Symmetrical rotary type is equipped with connecting rod at the top of two side's guide blocks, and front connects rod rear end and connecting rod front end rotary type in rear is equipped with connection
Block, link block are located above spill guide rod, and link block bottom is equipped with bolt, and installing frame upper left-hand is equipped with guide sleeve, and bolt is left
Across guide sleeve, bolt left end has been connected through a screw thread nut, nut right side and guide sleeve left contact at end.
Further, further include having bracing wire, telescopic band, tilt, elastic string, button and respiratory siphon, it is right on front side of installing frame
Portion is provided with groove, and right part is equipped with bracing wire on front side of installing frame, and bracing wire is located at below groove, and bracing wire right end is equipped with telescopic band, telescopic band
It is equipped with tilt, tilt front and rear sides are equipped with elastic string, and front elastic string front end and rear elastic string rear end are equipped with button,
Respiratory siphon is equipped with below tilt.
Further, further include thering are strut, bull stick and cotton cylinder, installing frame lower right side front and rear sides to be equipped with strut,
Rotary type is equipped with bull stick between two side's strut right end of front and back, and bull stick is located at installing frame right, and bull stick is equipped with cotton cylinder.
Further, further including flexible band, elastic webbing is uniformly provided in spill backing plate, elastic webbing is located under elastic cushion
Side.
When patient needs to carry out ophthalmologic operation, the head of patient is put on elastic cushion by doctor, then doctor further according to
The actual conditions of patient are adjusted the height of spill backing plate, and when patient needs to be turned up the height on head, doctor turns clockwise
Shake handle, rocking handle drives screw rod to rotate clockwise, and then drives wedge block to move right by threaded hole, wedge block band movable slider
It moves right on the slide rail, then makes to move up on the left of spill backing plate, to the head of patient be raised, when patient needs to drop
Bow portion height when, doctor rotates counterclockwise rocking handle, and rocking handle drives screw rod to rotate counterclockwise, and then drives wedge by threaded hole
Shape block is moved to the left, and wedge block band movable slider is moved to the left on the slide rail, then makes to move down on the left of spill backing plate, thus will
The head of patient reduces, and spring provides buffering when spill backing plate moves left and right, when doctor adjusts the height of head of patient
Afterwards, doctor is again fixed the head of patient with head fixing device, then can be carried out ophthalmologic operation, can so be made patient
When being performed the operation, the head of patient is fixed, prevent patient during operation headwork and influence surgical, into
And ensure surgical effect, improve surgical quality.
When doctor needs for be fixed on the head of patient, when the distance between two side sponge of front and back is larger, doctor
Bolt is pulled to the left, and bolt drives link block to be moved to the left, and bolt drives connecting rod inner end to be moved to the left, and then drives front and back two
The guide block of side moves inward, and guide block drives clamping plate, air ring and connecting plate to move inward, to make between two side sponge of front and back
Distance reduce, after distance is adjusted, doctor is again by nut tightening, and compressing guide sleeve, so by two side sponge of front and back it
Between distance fix, when the distance between two side sponge of front and back is larger, doctor first unscrews nut, then pushes bolt to the right,
Bolt drives link block to move right, and bolt drives connecting rod inner end to move right, and then drives the guide block of two sides of front and back outside
Side is mobile, and guide block drives clamping plate, air ring and connecting plate to move outward, thus increase the distance between two side sponge of front and back,
After distance is adjusted, doctor is again by nut tightening, and compressing guide sleeve, and then the distance between two side sponge of front and back is solid
It is fixed, so as to adjust to the distance for being suitble to patient, patient is made to feel more comfortable.
When patient needs to carry out ophthalmologic operation, doctor's telescopic band and tilt cover the face of patient, then
The button in two side's elastic string of front and back is connected again, and then tilt is fixed on to the face of patient, patient passes through respiratory siphon
It is breathed, the redundance of bracing wire is put into installing frame by subsequent doctor by groove again, can so prevent from carrying out
When operation, operating medicine falls to the face of patient, uncomfortable feeling is brought to patient, while being suspended to medical care prevented also from bracing wire
With personnel, and then tilt is pulled off, after doctor finishes operation, doctor first unlocks button, then by telescopic band and tilt from
The face of patient removes, and is then resetted again.
When patient is when performing the operation, after patients head is put on elastic cushion, the neck of patient can be put on cotton cylinder, in turn
Uncomfortable feeling will not be generated because performing an operation time length by making the cervical vertebra of patient, be adjusted the position of head placement in patient
When, bull stick can provide support for it, preferably protect the neck of patient.
When patient is when performing the operation, after patients head is put on elastic cushion, the head of patient can be moved down, elastic webbing
It will do it buffering, be not easy to operate when preventing the head of patient from declining too many, and then doctor being caused to perform an operation.
The present invention has the advantage that the present invention can be supported the head of patient by the spill backing plate and elastic cushion of setting
Firmly, and then for surgical support is provided, the head of patient can be fixed by the head fixing device of setting, prevents doctor
When performing an operation, patients head acts and influences surgical;Provided with wedge block, screw rod and rocking handle, doctor is by shaking rocking handle
Screw rod rotation is driven, and then wedge block is driven to move left and right, the height of patients head is then can adjust, makes patient's meeting in recumbency
It is more comfortable, while being also convenient for doctor and performing the operation, it is advantageously ensured that surgical effect, improves surgical quality.

After can carry out ophthalmologic operation, can so make patient when performing the operation, the head of patient is fixed, patient is prevented
During operation headwork and influence surgical, and then ensure surgical effect, improve surgical quality.
When doctor needs for be fixed on the head of patient, when the distance between two side sponge 146 of front and back is larger, doctor
Raw to pull bolt 149 to the left, bolt 149 drives link block 148 to be moved to the left, and bolt 149 drives 147 inner end of connecting rod to moving to left
It is dynamic, and then the guide block 142 of two sides of front and back is driven to move inward, guide block 142 drives clamping plate 143, air ring 144 and connecting plate 145
Move inward, so that the distance between two side sponge 146 of front and back be made to reduce, after distance is adjusted, doctor is again by nut
1411 screw, and compressing guide sleeve 1410, and then the distance between two side sponge 146 of front and back is fixed, when two side sponge of front and back
The distance between 146 it is larger when, doctor first unscrews nut 1411, then to the right push bolt 149, bolt 149 drive link block
148 move right, and bolt 149 drives 147 inner end of connecting rod to move right, and then drive the guide block 142 of two sides of front and back outward
Mobile, guide block 142 drives clamping plate 143, air ring 144 and connecting plate 145 to move outward, thus make two side sponge 146 of front and back it
Between distance increase, after distance is adjusted, doctor again screws nut 1411, and compressing guide sleeve 1410, and then by front and back
