Problems solved by technology

Due to the fact that the positions of the 16 joints are pre-fixed, combined with the fact that too many components are included in the physical system, its structure leads to many limitations and complications in setting up the device for the orthopedic surgeon, and in order to achieve the purpose of use, Demanding more cost, more time and more work from plastic surgeons unnecessarily

Embodiment Construction

[0074] In the robotic arrangement of external fixators, the first basic lambda module type ( figure 1 ) can be used with rings having a single row of holes; this is because the short and long legs of the lambda modules, together with their axes, lie in a single plane perpendicular to the axis of rotation of the swivel joints connecting them. The presence of short feet and long feet on the same plane may introduce small constraints on the length of the short feet and the number of changes in this length. able to pass image 3 The second class of first basic lambda modules seen in overcomes this situation. By making the axis of rotation of the swivel joint pass through a point on the axis of the long leg, the condition for making the short leg to take a greater length is fulfilled by this second category ( image 3 ). In this case, the axes of the short and long legs of the lambda modules lie in two separate planes that are parallel to each other and at the same time perpendi...

Abstract

The chevron anchor basically consists of two rings connected to each other by three main structural units called lambda modules, said rings having at least double rows of holes. There are four different lambda modules, two of which are base types and the others are subclasses of base types. In the first basic type there are three ball joints at the ends, a simple swivel joint connecting the long foot to the short foot, and two screw-nut pairs for changing the length of the foot. In the second basic type there are two ball joints at the end of the long feet, two universal joints at each end of the short feet, and two screw-nut pairs varying the length of the feet. By using only one type of lambda module it is possible to set the anchor in 512 different ways.

Description

technical field [0001] The title of the present invention is "Lambda Fixator". [0002] The present invention belongs to the multidisciplinary technical field where engineering technology meets the practice of orthopedic surgery in medicine. [0003] The field of use of the invention is orthopedics. [0004] The subject of the invention is a modular system that allows bone fragments to be brought externally to the desired position in order to overcome orthopedic problems in medicine such as limb fractures, deformities, etc. Background technique [0005] The most commonly used tools in orthopedic external fixation procedures are simple devices such as hinges, rods and pins and the classic framework system known as a pin holder. Various examples exist for such frames, such as one-sided, one-sided two-sided, two-sided one-sided (Donald et al., 1982; Seligson et al., 1982; Fernandez, 1985; Fernandez, 1992). Despite their architectural simplicity, a significant disadvantage of...
