Surgical Incision Guide for Multi-Plane Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical instruments with extremely sharp blades pose a risk of injury during handling and use, and existing methods for making precise incisions, such as multi-plane incisions, are difficult to perform accurately and repeatably.
Innovation Solution
A surgical instrument with a handle that selectively actuates a surgical blade between a safe position within an outer sleeve and an extended position, featuring a surgical incision guide to facilitate precise and repeatable multi-plane incisions while minimizing risk of injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an extremely sharp blade is used to create precise incisions, then manufacturing precision is improved, but the risk of injury to handlers increases
Solution Approach 1:
The surgical instrument is divided into separate functional components: an outer sleeve that can be retracted, an inner handle with the blade, and a surgical incision guide. This segmentation allows the blade to be protected when not in use while enabling precise incisions when deployed.
Solution Approach 2:
The surgical incision guide is pre-configured with marked positions and angular orientations before the surgical procedure. This preliminary preparation ensures that when the blade is extended, the surgeon can immediately make accurate multi-plane incisions without needing to measure or calculate during the procedure, maintaining precision while reducing handling complexity.
2Reliability
If a multi-plane incision is performed to ensure proper healing, then reliability is improved, but the difficulty of operation increases
Solution Approach 1:
The surgical incision guide contains pre-marked positions and angular orientations that define the multi-plane incision geometry before the procedure begins. This preliminary configuration allows the surgeon to simply follow the guide markings rather than calculate and measure each incision plane during surgery, making the complex multi-plane procedure easier to perform accurately.
Solution Approach 2:
The surgical incision guide acts as an intermediary tool between the surgeon and the tissue. It translates the complex requirements for multi-plane incisions into simple visual markings and physical guides that the surgeon can follow, reducing the operational difficulty while ensuring the reliability of proper healing outcomes.
3Manufacturing precision
If the blade is extended for use, then manufacturing precision can be achieved, but the risk of injury increases
Solution Approach 1:
The outer sleeve is designed to be dynamically retractable, allowing it to move from an extended protective position to a retracted operational position. This dynamic mechanism enables the blade to be protected during handling and packaging, then easily exposed when needed for precise incisions, and retracted again when the procedure is complete.
Solution Approach 2:
The blade is extracted from the protective outer sleeve only when needed for the surgical procedure. This separation allows the blade to remain protected and safe during handling, packaging, and storage, while enabling precise incisions when the blade is temporarily extended for use.

AI summary
A surgical blade may include a surgical incision guide configured to guide a surgical incision. The surgical incision guide may include one or more surgical incision guide marks. A surgical incision guide mark may be configured to provide information about a surgical incision. For example, a surgeon may compare a location of a surgical incision guide with a portion of a tissue to identify an incision depth. Illustratively, a surgeon may compare a location of a surgical incision guide with a portion of a tissue to identify an optimum incision depth to adjust an orientation of a surgical blade.
