Bone Cutting Apparatus with Clamp and Articulated Joints
Solution Overview
Problem
Conventional surgical instruments lack precision and stabilization features, making it difficult to remove osseous tissue without causing dural tears or compromising precision during procedures like laminectomy.
Innovation Solution
An apparatus with a fixed portion, a clamp mechanically coupled to the fixed portion for gripping bone tissue, and multiple bone cutting devices arranged around the clamp, which are oriented using linear and spherical joints to provide precise control and stabilization during surgical procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional surgical instruments are used for bone removal, then the procedure can be performed, but precision and stabilization are insufficient, increasing the risk of dural tears
Solution Approach 1:
The apparatus is divided into distinct functional segments: a stabilization member for anchoring, a clamp for securing the bone, and multiple bone cutting devices for precise cutting. This segmentation allows each component to perform its specific function optimally, with the stabilization member providing reliable anchoring and the cutting devices delivering precise cuts.
Solution Approach 2:
The clamp is positioned and secured to the bone before the cutting operation begins. This preliminary stabilization action ensures that the bone is firmly held in place, preventing movement during the cutting process and thereby eliminating dural tears while maintaining cutting precision.
2Ease of operation
If conventional instruments are used, then the procedure is simpler, but precision control is lost due to unrestricted applied force
Solution Approach 1:
The apparatus incorporates movable bone cutting devices that can be positioned and adjusted dynamically during the procedure. The devices are configured to move along predetermined paths, providing precise control over the cutting force and direction while maintaining ease of operation through the standardized apparatus design.
Solution Approach 2:
The bone cutting devices are designed to apply controlled forces within specific parameter ranges. The apparatus regulates the magnitude and direction of applied forces, transforming the unrestricted force application of conventional instruments into a controlled process that maintains both operational simplicity and cutting precision.
3Measurement precision
If multiple bone cutting devices are arranged around the clamp, then precision and control are improved, but device complexity increases
Solution Approach 1:
The apparatus employs multiple bone cutting devices that can be used for different cutting operations around the clamped bone. These devices share common mounting mechanisms and control systems, allowing them to perform multiple functions (different cutting angles, positions, and depths) while utilizing a standardized platform that reduces overall system complexity.
Solution Approach 2:
The clamp serves as an intermediary structure that anchors the bone and provides a stable reference point for positioning multiple bone cutting devices. This intermediary element simplifies the coordination between multiple devices by providing a common attachment point and alignment reference, thereby reducing the complexity of managing multiple cutting tools.
