The inner surface of described ball-and-socket and the outer surface of ball clack are equipped with form of spherical particles projection.
The hinge connecting ball clack is provided with torsion spring.
Resilient sleeve is set with at the root of the ball clack arranging hinge.
Air packing is provided with at the root of armed lever valve.
After adopting technique scheme, can draw by all-directional rotation during this surgical operation self-retractor uses, without working angle, easy to use, flexible operation is reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the cross section sectional view of ball-joint.
Detailed description of the invention
As shown in Figure 1, surgical operation self-retractor of the present invention comprises stiff end 1 for being connected and fixed bar, for connecting the movable end 2 of operating theater instruments, stiff end 1 and movable end 2 are the fixture for being connected bed head frame and operating theater instruments respectively, as the multiple existing detachable connecting devices such as bolt type bindiny mechanism, clamped-in style bindiny mechanism, card slot type bindiny mechanism all can use.In operation, be fixedly mounted on the fixing point of the head of a bed by stiff end 1, be arranged on movable end 2 by traction apparatuss such as operation hooks, the Distance geometry angle adjusted between stiff end 1 and movable end 2 can realize drawing fixing effect in operation.
As shown in Figure 1, between stiff end 1 and movable end 2, be provided with rocking arm, described rocking arm comprise armed lever 4, the ball-joint be arranged on armed lever 4, ball-joint can be one, also can arrange two or more as required.
As shown in Figure 1 and Figure 2, described ball-joint comprises ball-and-socket 5, be arranged on ball clack 6 in ball-and-socket 5 and air bag 7, and in order to improve frictional force, the inner surface of described ball-and-socket 5 and the outer surface of ball clack 6 are equipped with form of spherical particles projection.Described ball-and-socket 5 is fixedly mounted on a section of armed lever 4, described ball clack 6 is hinged on another section of the armed lever 4 of ball-and-socket 5 correspondence, plural ball clack 6 arranges in hollow ball-shape around being arranged on air bag 7 around, ball clack 6 is in petal-shaped, if adopt the design of two ball clacks, then two ball clacks can be oppositely arranged, air bag 7 is between two ball clacks, if adopt the ball clack of more than three as shown in Figure 2, then multiple ball clack is in angularly annular array, by air bag 7 around wherein, when air bag 7 inflation time, ball clack can be strutted.
Described air bag 7 is with air bag valve, and the section that described air bag valve is inserted into armed lever 4 is communicated with the air flue 8 be arranged in armed lever 4, and it can be threaded that air bag valve is connected with the section of armed lever 4, also can be interference fit or is glued; The sidewall of armed lever 4 is provided with the armed lever valve 12 being communicated with described air flue 8, described armed lever valve 12 is provided with gas nozzle cap 13 by screw thread, described gas nozzle cap 13 connects gas tube 14 by notch, and the sidewall of the armed lever valve 12 of gas nozzle cap 13 covering is provided with bleeder port 15.The top of gas nozzle cap 13 is provided with the through hole holding gas tube 14, the end of gas tube 14 is provided with the boss that can be connected in gas nozzle cap 13, gas tube 14 can be communicated with air flue 8 when gas nozzle cap 13 connects time gas tube 14 is arranged on armed lever valve 12, the sidewall of gas nozzle cap 13 blocks bleeder port 15 simultaneously, places gas leakage.After armed lever 4 is adjusted angle, utilize the aerating devices such as high-pressure pump to inflate in gas tube 14, air bag 7 inflation can be made, ball clack is strutted, by ball-and-socket 5 locking, position is fixed.After having performed the operation, when needing return, as long as unclamp gas nozzle cap 13, avoid bleeder port 15, the high pressure in air flue 8 disappears, and namely ball-and-socket 5 can freely rotate.
In order to realize ball clack strut after can free return, at least can by two schemes, the first is provided with torsion spring 10 as shown in Figure 2 on the hinge 9 connecting ball clack 6, the resistance that ball clack 6 overcomes torsion spring when air bag 7 is inflated time outwards struts, after the tension force disappearance of air bag 7, the elastic force of torsion spring promotes ball clack 6 and shrinks.Another technical scheme as shown in Figure 1, resilient sleeve 11 is set with at the root of the ball clack 6 arranging hinge 9, resilient sleeve 11 is sleeved on outside armed lever 4, a part for resilient sleeve 11 covers the root of ball clack 6, the resistance that ball clack 6 overcomes resilient sleeve 11 when air bag 7 is inflated time outwards struts, after the tension force disappearance of air bag 7, the elastic force of resilient sleeve 11 promotes ball clack 6 and shrinks.
In addition, in order to improve the sealing of gas nozzle cap 13, being provided with air packing 16 at the root of armed lever valve 12, gas nozzle cap 13 screw thread can be avoided like this to leak gas.
