Abstract
A holding device for medical instruments, having a bracket on which at least one medical instrument can be affixed, at least one joint to position the bracket and a weight-relieving system to compensate the bracket load. The holding device is of compact and light structure and for cleaning purposes is completely autoclavable together with the bracket. The weight-relieving system is configured as a resetting element that is coupled with the bracket and is made of a material that essentially includes a plateau stress.
Claims18
A holding device for medical instruments, the holding device comprising:
- a bracket on which at least one medical instrument can be affixed,
- at least one joint to position the bracket, and
- a weight-relieving system to compensate a bracket load, the weight-relieving system being configured as a resetting element coupled with the bracket and made of a material that comprises a plateau stress, the resetting element being pre-tensed by the bracket load until the resetting element reaches the plateau stress, wherein the resetting element is mounted at one end in a non-movable configuration on a first bracket part and at an opposite end on a second bracket part that is displaceable with respect to the first bracket part by the at least one joint;
- wherein the resetting element is disposed in a guide tube that provides guidance of said weight-relieving system, wherein the guide tube is slidable along an axis of a housing of the first bracket part;
- and
- wherein the resetting element is mounted to the displaceable second bracket part by a flexible element, the flexible element coupled to both the resetting element and the displaceable second bracket part provides a uniform, non-jerking transmission of forces exerted by the displaceable second bracket part to the resetting element.
A holding device for medical instruments, the holding device comprising:
- a bracket on which at least one medical instrument can be affixed,
- at least one joint to position the bracket, and
- a weight-relieving system to compensate a bracket load, the weight-relieving system being configured as a resetting element coupled with the bracket and made of a material that comprises a plateau stress, the resetting element being pre-tensed by the bracket load until the resetting element reaches the plateau stress, wherein the resetting element is mounted at one end in a non-movable configuration on a first bracket part and at an opposite end on a second bracket part that is displaceable with respect to the first bracket part by the at least one joint;
- wherein the resetting element is disposed in a guide tube that provides guidance of said weight-relieving system, wherein the guide tube is slidable along an axis of a housing of the first bracket part;
- and
- wherein the resetting element within the guide tube is positioned on an outer contour of the first bracket part.
