Medical Positioning Device

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes a medical positioning device designed for use in surgical procedures, particularly orthopedic operations such as bone fracture treatments. The device consists of two carriage assemblies for positioning two pins, each with fully adjustable orientation using spherical joints that provide three rotational degrees of freedom. An extension assembly allows for precise adjustment of the distance between the two pins, enabling controlled repositioning or stabilization of bones during surgery.

Use CasesContent extracted from patent full text and abstract with AI.

• Orthopedic surgery for repositioning fractured bones, such as feet, hands, arms, or legs
• External fixation during healing of complex bone fractures
• Stabilization of body parts during surgical procedures to ensure correct alignment
• Trauma or emergency surgery where bone alignment needs to be rapidly corrected
• Use in pediatric or adult orthopedic procedures due to the adjustable nature of the device
• Research and training in surgical positioning techniques

BenefitsContent extracted from patent full text and abstract with AI.

• Allows precise adjustment of pin orientation and distance for accurate bone repositioning
• Reduces device bulk and complexity, making it easier and more comfortable for surgeons to handle
• Improves stability and strength at the fixation points, supporting better bone alignment and healing
• Accommodates a variety of body parts and patient sizes due to flexible design
• Quick and secure attachment/detachment reduces risk of procedural errors or instrument dropping
• Can incorporate force measurement for monitoring applied forces during repositioning, increasing safety and outcome predictability

Patent Abstract

The present invention relates to a medical positioning device, comprising a first carriage assembly configured for mounting a first pin, wherein the orientation of the first pin is adjustable by means of a first spherical joint with three rotational degrees of freedom with an angular range of at least ± 10° each, a second carriage assembly configured for mounting a second pin, wherein the orientation of the second pin is adjustable by means of a second spherical joint with three rotational degrees of freedom with an angular range of at least ± 10° each and an extension assembly configured for adjusting a distance between the first pin and the second pin.
