Surgical Access Port with Integrated Anchoring and Modular Inserts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical access devices for minimally invasive procedures require sutures for anchoring, which cause trauma, complexity, and obstructions, and often necessitate multiple access ports for instruments like cameras and light sources, increasing procedural difficulty and recovery time.
Innovation Solution
A surgical access port with convex and concave anchoring regions, along with optional protuberances and an atraumatic spur, secures itself to the abdominal wall without sutures, and includes an integrated or modular insufflation conduit and adapter plugs for various instruments, reducing the number of access ports needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sutures are used to anchor the trocar, then the trocar can be secured to the abdominal wall, but patient trauma increases and procedural complexity increases
Solution Approach 1:
The invention extracts and eliminates the suture component from the anchoring system. Instead of using separate sutures to secure the trocar, the trocar housing itself incorporates integrated anchoring features (convex and concave anchoring regions with tie-down features) that directly engage with the abdominal wall tissue, removing the need for external sutures and their associated trauma.
Solution Approach 2:
The invention merges the anchoring function with the trocar housing structure. The convex and concave anchoring regions are integrated into the trocar body, combining the securing mechanism with the access device itself, thereby eliminating separate anchoring components like sutures and reducing procedural steps.
2Adaptability or versatility
If multiple access ports are used for instruments, then all necessary instruments can be introduced, but procedural complexity increases and recovery time increases
Solution Approach 1:
The invention creates a universal access device that can accommodate multiple different surgical instruments through a single port. The trocar housing is designed with features that allow various instruments (scissors, staplers, graspers, cameras, light sources) to be introduced through the same access point, eliminating the need for multiple separate access ports.
Solution Approach 2:
The invention resolves the spatial constraint by transitioning from a single-dimensional approach (multiple ports along the abdominal wall) to a multi-dimensional solution (a single port with three-dimensional instrument pathways and articulating mechanisms that allow instruments to be directed at various angles into the abdominal cavity).
3Reliability
If sutures are used for anchoring, then the trocar can be secured, but obstructions are created near the surgical site
Solution Approach 1:
The invention removes the suture material and external anchoring elements from the surgical field. By integrating the anchoring mechanism into the trocar housing itself, the surgical site remains clear of obstructions, allowing the surgeon unobstructed access and visibility for manipulating instruments during the procedure.

AI summary
An access port is disclosed for use in minimally invasive surgical procedures performed within a patient's abdominal cavity, which includes a body defining a bore configured to guide at least one surgical instrument into the abdominal cavity, and concave and convex anchoring regions for securing the access port relative to the abdominal cavity.
