Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current minimally invasive surgical procedures for prostate enlargement, such as laser enucleation, face challenges in effectively handling internal bleeding, ablation, and separation of the prostate from its capsule, requiring improved tools for precise and efficient tissue manipulation.
Innovation Solution
A multifunctional surgical apparatus featuring a base with pivotally coupled separation tongs and an optical fiber cable that delivers optical energy for cutting, ablation, and coagulation, allowing for precise tissue separation and bleeding control through a wedge-shaped tip and controlled movement of the tongs between open and closed positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If laser enucleation is used for minimally invasive prostate surgery, then the intrusiveness of the procedure is reduced, but the ability to handle internal bleeding and separate prostate from capsule is insufficient
Solution Approach 1:
The patent combines multiple functions (cutting, coagulation, and mechanical separation) into a single surgical apparatus. The separator includes both optical energy delivery capability and mechanical tong structures that can grasp and separate tissue, allowing simultaneous addressing of bleeding control and tissue separation needs while maintaining minimally invasive access through the urethra
Solution Approach 2:
The surgical apparatus is designed to perform multiple functions: delivering optical energy for cutting and coagulation, mechanically grasping tissue with tongs, and separating prostate from capsule. This multi-functional design eliminates the need for multiple separate instruments, improving reliability while maintaining the minimally invasive approach
2Manufacturing precision
If optical energy beam is delivered between separation tongs at a centered point, then precise tissue separation is achieved, but the complexity of the apparatus increases
Solution Approach 1:
The optical fiber is positioned within the separator structure itself, using the separator's own geometry to define the beam delivery path. The fiber terminates at a location that automatically positions the beam between the tongs when they are in the closed position, eliminating the need for complex external positioning systems or active control mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise prostatectomy procedures with reduced tissue damage, effective enucleation, and efficient hemostasis by using optical energy to coagulate bleeding sites, improving the handling of internal bleeding and separation from the capsule during minimally invasive surgeries.
Implementation Method 1
a cable coupled to the base, the cable including an optical fiber, where the base is arrange to position the optical fiber to aim an optical energy beam from the optical fiber out from the base
Implementation Method 2
Enables precise prostatectomy procedures with reduced tissue damage, effective enucleation, and efficient hemostasis by using optical energy to coagulate bleeding sites
Implementation Method 3
laser enucleation of the prostate. During this procedure enucleation of the anatomic lobes of the prostate are being enucleated. The enucleation procedure are often accomplished by utilizing laser energy for cutting/ablating portion of the prostate

AI summary
Systems and methods for a multifunction surgical apparatus are provided. In one embodiment, a surgical separator comprises: a base; a plurality of separation tongs each movably coupled to the base at their proximal end, wherein the tongs have distal ends each having a blunt profile; a cable coupled to the base, the cable including an optical fiber, where the base is arrange to position the optical fiber to aim an optical energy beam from the optical fiber out from the base and between the tongs at a centered point between the distal ends; wherein the cable further includes at least one element providing a control signal that controls operation of the tongs to move between and open position and a closed position; wherein when the distal ends of each of the tongs are positioned together into the closed position, the exterior profile of the tongs forms a wedge shape having a tip where the tongs meet.
