Detailed description of the invention
The following is the specific embodiment of the present invention and combine accompanying drawing, the technical side to the present invention
Case is further described, but the present invention is not limited to these embodiments.
As depicted in figs. 1 and 2, this operation is horizontal in support body 1 upper end with leg positioner
To being provided with sliding tube 2, in sliding tube 2, axially it is equipped with slip inner tube 3, is sliding
Inner tube 3 outer end connects segmental support 4, and being provided with on segmental support 4 can be sliding along segmental support 4
Dynamic connection seat 5, is provided with the foot support 6 for positioning leg portions connecting on seat 5, even
Joint chair 5 is provided with front rotary case 7, is provided with and matches with front rotor 8 on foot support 6
The front rotor 8 closed, uniform ring on the end face of front rotary case 7 forward-facing rotor 8
Around some prelocalization hole 7a is distributed, front rotor 8 is provided with prelocalization pin 9, and
Rotary case 7 and front rotating disk before when the inner of current alignment pin 9 screws in the 7a of prelocalization hole
Body 7 is connected.
When patient lies in operating-table and foot is positioned on foot support 6, doctor's lower limb to patient
When portion is operated, owing to operation needs, need patient legs is carried out by a small margin
Rotation, by prelocalization pin 9 is screwed out so that front rotor 8 can relatively before rotating disk
Body 7 circumferentially rotates, when current operation body 8 turns to specify position, by prelocalization pin 9
Again screw in corresponding prelocalization hole 7a, so that front rotor 8 and front rotating disk
Body 7 is located by connecting.
By coordinating of front rotor 8 and front rotary case 7 so that doctor is to patient legs
Energy precise fine-adjustment, it is to avoid owing to causing patient legs to rotate excessively by rotation segmental support 4
Situation.
Further, locking pin 10 and front locking pin before being also equipped with on front rotor 8
10 the inners are close proximity on front rotary case 7 end face, before front locking pin 10 outer end is provided with
Joystick 11 and front locking pin 10 and front rotating disk can be made when pulling front joystick 11
Body 7 end face disengages.When current alignment pin 9 screws in the 7a of prelocalization hole, pass through
Front locking pin 10 the inner is close proximity on front rotary case 7 end face, so that front rotary case 7
It is tightly pressed together with front rotor 8, so that front rotary case 7 is tight with front rotor 8
Close connected, and during rotor 8, pull front joystick 11 and make front lock before needs rotate
Tight pin 10 disengages with front rotary case 7 end face, thus fixed before prelocalization pin 9 departs from
After the hole 7a of position, front rotor 8 can circumferentially rotate by relatively front rotary case 7.Front locking pin

Even.
Further, the sidewall of segmental support 4 uniformly offers some spacing hole 4a,
Connecting the wing plate that seat 5 be arranged in parallel by two and be connected to form, two wing plates are fixedly arranged on front rotating disk
On body 7 and point be listed in segmental support 4 both sides, on a wing plate, spacer pin is installed wherein,
And connect seat 5 when spacer pin is arranged in spacing hole 4a connected with segmental support 4.When needing
Will by patient legs's upwards lifting or downwards under press time, spacer pin is revolved at spacing hole 4a
Go out so that connecting seat 5 can slide into specific bit along the radians slip of segmental support 4
Postpone, spacer pin is screwed in again to corresponding spacing hole 4a, so that connect seat
5 reorientate with segmental support 4 and to be connected.
Further, rotor 13 after slip inner tube 3 outer end is provided with, at segmental support 4
It is provided with the rear rotary case 12 matched with rear rotor 13, faces at rear rotary case 12
On the end face of rear rotor 13 uniform ring around be distributed some after position hole, at rear rotor
13 are provided with rear alignment pin 14, and when after the inner of alignment pin 14 screw in hole, rear location
After time middle, rotary case 12 is connected with rear rotary case 12.When patient legs is carried out greatly by needs
During rotational motion, segmental support 4 inner tube 3 of relatively sliding is needed to circumferentially rotate, in operation
Time, first rear alignment pin 14 is screwed out so that rear rotor 13 can relatively rear rotary case 12
Circumferentially rotate, when rear rotor 13 turns to specify position, by rear alignment pin 14 weight
New screw-in positions in hole after corresponding, so that rear rotor 13 and rear rotary case
12 are located by connecting.
Further, after rear rotor 13 being also equipped with locking pin 15 and after lock
Pin 15 the inner is close proximity on rear rotary case 12 end face, is provided with in rear locking pin 15 outer end
Rear joystick 16 and can make when pulling rear joystick 16 rear locking pin 15 with rear turn
Disk body 12 end face disengages.When rear alignment pin 14 screws in hole, rear location, logical
Later locking pin 15 the inner is close proximity on rear rotary case 12 end face, so that rear rotating disk
Body 12 is tightly pressed together with rear rotor 13, so that rear rotary case 12 and rear rotation
Body 13 is closely connected, and during rotor 13, pulls rear joystick after needs rotate
16 make rear locking pin 15 disengage with rear rotary case 12 end face, thus at rear alignment pin
After positioning hole after 14 disengagings, rear rotor 13 can circumferentially rotate by relatively rear rotary case 12.
Rear locking pin 15 primarily serves safety effect, coordinates so that rear rotating disk with rear alignment pin 14
Body 12 and rear rotor 13 can closely be connected, it is to avoid in operation process, foot support 6 goes out
The phenomenon now rocked.
Further, bearing block 20 is installed in sliding tube 2 and on bearing block 20
It is equipped with left and right adjusting screw mandrel 22, in slip inner tube 3 the inner, thread bush 21 is installed, left

The outer end of right regulation screw mandrel 22 is stretched out sliding tube 2 and is provided with handwheel 23 in this end.
By rotating handwheel 23, left and right adjusting screw mandrel 22 is circumferentially rotated, thus drive slip
Inner tube 3 axially moves linearly along sliding tube 2 so that segmental support 4 energy support body 1 relatively is straight
Line moves horizontally.
Further, support body 1 tilts to be fixed with sleeve pipe 1a, wears in sleeve pipe 1a
It is provided with crane 24 and crane 24 axially can move linearly along sleeve pipe 1a, crane
24 upper ends are connected with support body 1, are provided with elevating screw 25 outside sleeve pipe 1a, lift silk
Bar 25 lower end is provided with runner 27, and the other end is threaded heightens cylinder 26, heightens cylinder
In 26 upper ends stretch to crane 24 and it is articulated and connected with crane 24.Elevating screw 25
It is axially positioned on sleeve, so that when runner 27 rotates, elevating screw 25 is also
Axial rotation therewith, threadeds with elevating screw 25 owing to heightening cylinder 26, therefore adjusts
High cylinder 26 can move up and down along elevating screw 25, thus drives crane 24 along sleeve pipe
1a oscilaltion, adjusts the terrain clearance of segmental support 4, and the patient meeting different height makes
With.
