PCT No. PCT/AU85/00154 Sec. 371 Date Mar. 10, 1986 Sec. 102(e) Date Mar. 10, 1986 PCT Filed Jul. 15, 1985 PCT Pub. No. WO86/00521 PCT Pub. Date Jan. 30, 1986.A leg holding and positioning device for use in surgical operative procedures comprising a housing (10) which is adapted for attachment to the rail (12) of an operating table (not shown) by means of a member (11) and a clamp (13) the housing having projecting from it a shaft (14) which is connected to a viscous damper or other device within the casing (10) to control rotation of the shaft (14), such device being associated with the control knob (18) whereby the shaft may be fixed in any one of a number of rotated positions. A member (25) is attached to one end of the shaft (14) and in use lies alongside the operative leg of a person on the operating table, the leg being secured to the member (25) by means of the bracket (32) and straps (35) and (36). The member (25) is preferably also capable of rotation about a virtual center at a point constituting the approximate center of a hib joint of a person on the operating table by means of pivotal movement between the member (25) and the shaft (14) and is arranged to be releasably secured in any of a plurality of rotated positions by means of holes arranged in an arc on the member (25) and engageable by a pin (28) passing through the shaft (14). Movement of the device involving rotation of the rotatable shaft (14) corresponds to the flexion or extension of the hip joint and movement of the second member (25) about the said virtual center corresponds to the abduction or adduction of the hip joint. |
