Root at the ball clack that hinge is set is set with resilient sleeve.
Root at armed lever valve is provided with air packing.
Adopt after technique scheme, during this surgical operation self-retractor uses, can draw by all-directional rotation, 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 cutaway view of ball-joint.
The specific embodiment
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 is respectively the fixture for being connected bed head frame and operating theater instruments with movable end 2, 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, stiff end 1 is fixedly mounted on the fixing point of the head of a bed, the traction apparatuss such as operation hook are arranged on movable end 2, adjust distance between stiff end 1 and movable end 2 and angle and can realize and in operation, draw fixing effect.
As shown in Figure 1, between stiff end 1 and movable end 2, be provided with rocking arm, described rocking arm comprises armed lever 4, is arranged on the ball-joint on armed lever 4, and ball-joint can be one, and two or more also can be set as required.
As shown in Figure 1 and Figure 2, described ball-joint comprises ball-and-socket 5, is arranged on ball clack 6 and air bag 7 in ball-and-socket 5, and in order to improve frictional force, the outer surface of the inner surface of described ball-and-socket 5 and ball clack 6 is 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 armed lever 4 of ball-and-socket 5 correspondences, plural ball clack 6 is arranged and is hollow ball-shape around being arranged on air bag 7 around, ball clack 6 is petal-shaped, if adopt the design of two ball clacks, two ball clacks can be oppositely arranged, air bag 7 is between two ball clacks, if adopt three above ball clacks as shown in Figure 2, multiple ball clacks are equal angles annular array, air bag 7, around wherein, in the time of air bag 7 inflation, can be strutted ball clack.
Described air bag 7 is with air bag valve, and described air bag valve is inserted on the section of armed lever 4 and is communicated with the air flue 8 being arranged in armed lever 4, and it can be to be threaded that air bag valve is connected with the section of armed lever 4, can be also interference fit or is glued; The sidewall of armed lever 4 is provided with the armed lever valve 12 that is communicated with described air flue 8, on described armed lever valve 12, by screw thread, gas nozzle cap 13 is installed, described gas nozzle cap 13 connects gas tube 14 by notch, on the sidewall of the armed lever valve 12 covering at gas nozzle cap 13, is provided with bleeder port 15.The top of gas nozzle cap 13 is provided with the through hole that holds gas tube 14, the end of gas tube 14 is provided with the boss that can be connected in gas nozzle cap 13, in the time that connecting gas tube 14 and be arranged on armed lever valve 12, gas nozzle cap 13 gas tube 14 can be communicated with air flue 8, the sidewall of gas nozzle cap 13 is blocked bleeder port 15 simultaneously, places gas leakage.After armed lever 4 is adjusted to angle, utilize the aerating devices such as high-pressure pump to the interior inflation of gas tube 14, can make air bag 7 inflations, ball clack is strutted, by ball-and-socket 5 lockings, 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 ball-and-socket 5 can freely rotate.
For can free return after realizing ball clack and strutting, at least can be by two schemes, the first is provided with torsion spring 10 as shown in Figure 2 on the hinge 9 that connects ball clack 6, the resistance that ball clack 6 overcomes torsion spring in the time that air bag 7 is inflated outwards struts, after the tension force of air bag 7 disappears, the elastic force of torsion spring promotes ball clack 6 and shrinks.Another technical scheme as shown in Figure 1, root at the ball clack 6 that hinge 9 is set is set with resilient sleeve 11, resilient sleeve 11 is sleeved on armed lever 4 outsides, a part for resilient sleeve 11 covers the root of ball clack 6, the resistance that ball clack 6 overcomes resilient sleeve 11 in the time that air bag 7 is inflated outwards struts, after the tension force of air bag 7 disappears, 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, be provided with air packing 16 at the root of armed lever valve 12, can avoid like this gas nozzle cap 13 screw thread gas leakage.
