Surgical Guide Device for Percutaneous Insertion of Elongated Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for inserting elongated members, such as rods, into patients often require large incisions, result in significant blood loss, increased anesthesia time, higher infection risk, longer recovery times, and patient discomfort due to the materials' tendency to bend or flex during insertion.
Innovation Solution
A guide device with a channel is designed for percutaneous insertion, featuring a distal end inserted into the patient and a proximal end outside, allowing for accurate placement of elongated members with minimal tissue damage, using a pivoting carriage or freehand technique, and adjustable or flexible channel sizes to accommodate various member sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a large incision is made to insert the elongated member, then the member can be inserted, but patient trauma and blood loss increase
Solution Approach 1:
The guide device is inserted through a small incision first, creating a tunnel or pathway within the patient's tissue. The elongated member is then nested within this guide device and pushed through the established pathway. This nesting approach allows the larger member to be inserted through a small incision by utilizing the guide as a conduit, thereby minimizing patient trauma while maintaining insertion capability.
2Ease of operation
If the elongated member is made flexible to ease insertion, then insertion is easier, but placement precision decreases
Solution Approach 1:
The guide device is inserted and positioned at the target site before the elongated member is inserted. The guide remains in place as a rigid or semi-rigid pathway, providing preliminary positioning and directional guidance. When the flexible elongated member is pushed through the guide, it is constrained to follow the pre-established accurate pathway, thereby maintaining placement precision despite the member's flexibility.
3Ease of manufacture
If traditional insertion methods are used, then the procedure is straightforward, but surgery time and anesthesia time increase
Solution Approach 1:
The insertion procedure is segmented into two distinct steps: first inserting the guide device through a small incision to establish a pathway, then inserting the elongated member through the guide. This segmentation allows the guide to be inserted quickly through minimal tissue disruption, and the member to be subsequently inserted through the pre-formed pathway, thereby reducing overall surgery time and anesthesia time while maintaining procedural simplicity.

AI summary
The present application is directed to guides for inserting an elongated member into a patient. The guide generally includes an elongated shape with a distal end that is positioned within the patient, and a proximal end that may be positioned outside of the patient. The guide may include a channel formed between sidewalls. The channel is sized to receive the elongated member and guide the member into a predetermined location within the patient. In one embodiment, the guide is used with an insertion device that may include a pivoting carriage for initially inserting the guide and then the elongated member into the patient. The guide may also be used in a freehand technique that is positioned specifically within the patient by the surgeon.
