Leg fixing support for bone marrow puncture operation on children

Abstract

The invention discloses a leg fixing support for a bone marrow puncture operation on children, which comprises a thigh fixing sleeve, a shank fixing sleeve and a movable bone penetrating window, wherein the thigh fixing sleeve and the shank fixing sleeve are hinged through a rotating shaft with a locking nut and a large rotating wheel, the shank fixing sleeve comprises a lower shank fixing sleeveand an upper shank fixing sleeve, wherein the lower shank fixing sleeve is connected with a steel plate through an elastic belt and is provided with a foot sleeve, the connecting end surfaces of the lower leg fixing sleeve and the upper leg fixing sleeve are provided with bone penetrating windows matched with each other, and a group of fixing belts with fixing screws are symmetrically arranged onthe outer walls of the thigh fixing sleeve, the lower leg fixing sleeve and the upper leg fixing sleeve. According to the leg structure of children, the leg of the child is fixed on a sickbed by utilizing the physical mechanical action and the pneumatic filling principle, so that the leg of the child needing to be punctured can be firmly fixed on the support in favor of the operation. The moving window can directly calculate the bone penetrating position according to the distance of the fixed foot so as to manually adjust the window and accurately find the required operating part.
