Abstract
A leg positioning device for X-ray filming has a support with which the leg can be fixedly held at two spaced locations, a pressure element which can apply incrementally variable pressure to the leg intermediate these locations, and a device for measuring the applied pressure so that the same can be exactly reproduced whenever desired.
Claims13
A leg positioning device for X-ray filming, comprising supporting means, including an elongated guide member, a pair of laterally projecting outriggers mounted on respective end portions of said guide member for sliding movement lengthwise thereof, and a plurality of leg-engaging and retaining elements on the respective outriggers, so that a leg engaged by said elements extends lengthwise of said guide member from one to the other of said outriggers, said elements comprising one member for engaging and retaining a foot of the leg, and a pair of members for engaging and retaining the leg above the foot, any two of said members being jointly usable at one time;
- and pressure means for applying to the engaged leg intermediate said elements reproducible pressure acting in direction transversely of the elongation of said guide member and hence of the leg, said pressure means comprising a pressure-exerting pusher component, mounting means mounting said pusher component on said guide member for movement lengthwise of the elongation of the same as well as transverse to said elongation toward and away from an engaged leg, and means for measuring and visually indicating the pressure which is being exerted by said pusher component upon the leg.
A leg positioning device for X-ray filming, comprising supporting means, including an elongated guide member, a pair of laterally projecting outriggers mounted on respective end portions of said guide member for sliding movement lengthwise thereof, and a plurality of leg-engaging and retaining elements on the respective outriggers, so that a leg engaged by said elements extends lengthwise of said guide member from one to the other of said outriggers, said elements comprising one member for engaging and retaining a foot of the leg, and a pair of members for engaging and retaining the leg above the foot, any two of said members being jointly usable at one time;
- said one member comprising a heel-support portion, a sole-support portion projecting from said heel-support portion, a pair of lateral support portions engageable with the lateral sides of a foot, a single pin beneath said heel support portion for insertion into a hole of the respective outrigger so that the one member can be turned about an axis defined by the pin, and two pairs of pins at respective lateral sides of said one member and receivable in additional holes of the respective outrigger to fixedly secure said one member thereto in respective different orientations;
- and pressure means for applying to the engaged leg intermediate said elements reproducible pressure acting in direction transversely of the elongation of said guide member and hence of the leg.
