Surgical Leg Holder Angular Adjustment Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical leg holders, such as the Hana®, are expensive, occupy valuable operating room space, and can cause post-operative peroneal nerve pain, failing to provide a cost-effective solution for supporting and manipulating patient legs during surgery without leading to medical professional fatigue and inadequate surgical exposure.
Innovation Solution
A surgical leg holder with a frame capable of angular adjustment, featuring handles and fasteners for secure leg positioning, including straps or clamps, and padded components for comfort, designed to reduce the burden on medical professionals and improve surgical exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a surgical table like Hana® is used to provide linear distraction and mechanical traction, then surgical exposure is improved, but cost increases, operating room space is consumed, and post-operative peroneal nerve pain occurs
Solution Approach 1:
The invention extracts the essential function of leg manipulation and support from the complex Hana® surgical table system. By isolating the leg holder as a separate, portable device with specific manipulation capabilities, it achieves surgical exposure improvement without requiring the full surgical table infrastructure, thereby eliminating associated harms.
Solution Approach 2:
The leg holder is designed as a simpler, more affordable alternative to the expensive Hana® surgical table. The device uses basic mechanical components (frame, joint, handles, fasteners) that can be manufactured at lower cost, making it a cost-effective solution that doesn't require the expensive infrastructure of traditional surgical tables.
2Ease of operation
If the Hana® surgical table is used to provide constant mechanical traction, then leg manipulation is improved, but operating room space is consumed
Solution Approach 1:
The invention segments the leg manipulation function from the large surgical table system. By creating a separate, focused leg holder device that attaches to the patient's leg independently, it performs leg manipulation tasks without requiring the extensive space of a full surgical table setup.
Solution Approach 2:
The leg holder operates in a different spatial dimension by attaching directly to the patient's leg and providing manipulation capabilities in multiple planes (angular adjustment about the joint) without occupying floor space. This transforms the problem from a space-consuming table-based system to a patient-centric, space-efficient device.
3Ease of manufacture
If medical professionals manually support and manipulate the patient's leg, then no expensive equipment is needed, but medical professional fatigue increases leading to inadequate surgical exposure
Solution Approach 1:
The leg holder acts as an intermediary device between the medical professional and the patient's leg. It provides mechanical leverage and support, allowing professionals to manipulate the leg with less physical effort while maintaining adequate surgical exposure. The device mediates the interaction, reducing fatigue while preserving surgical quality.
Solution Approach 2:
The leg holder is designed to be easily attached and adjusted by medical professionals themselves without requiring complex equipment or additional personnel. The simple fastening system and intuitive handles allow the device to serve itself once positioned, reducing the ongoing physical burden on professionals while maintaining surgical exposure.

AI summary
A surgical leg holder for manipulating a leg during surgery that includes a frame comprising a proximal femoral portion, a joint and a tibial portion distal the joint, the frame capable of angular adjustment about the joint. The surgical leg holder also includes one or more handles extending from the frame; and one or more fasteners to circumscribe at least a portion of a leg to secure the leg to the frame.
