Microanastomosis Forceps with Integrated Suction and Dissection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During microvascular anastomosis procedures, the need to frequently remove or reposition forceps to accommodate other surgical instruments disrupts the surgical site, leading to inefficiencies and potential complications.
Innovation Solution
The development of microanastomosis forceps with integrated suction ports and a micro-hook blunt dissecting tip, allowing the forceps to remain within the surgical site while providing suction for clearing debris and dissecting tissue as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If forceps are removed or repositioned frequently to accommodate other surgical instruments, then the surgical site can be accessed by additional tools, but the surgical procedure efficiency decreases and the surgical site stability is disrupted
Solution Approach 1:
The patent combines multiple surgical functions into a single forceps instrument by integrating suction ports and a micro-hook blunt dissecting tip directly onto the forceps structure. This merging eliminates the need to remove the forceps to access other instruments, as the forceps itself now provides suction and tissue dissection capabilities alongside its gripping function, thereby maintaining surgical site stability and improving procedural efficiency
Solution Approach 2:
The forceps is designed with multi-functionality by incorporating suction ports on the shaft and a micro-hook blunt dissecting tip at the distal end. This universal design allows the single instrument to perform gripping, suctioning of debris/fluid, and blunt dissection of tissue, replacing the need for multiple separate instruments and eliminating frequent instrument exchanges during the surgical procedure
2Reliability
If multiple separate instruments are used for suction and dissection, then specific functions are performed effectively, but the number of instrument exchanges increases
Solution Approach 1:
The patent merges the functions of separate suction instruments and dissection instruments into the forceps structure itself. Suction ports are integrated on the forceps shaft with connected suction hoses, and a micro-hook blunt dissecting tip is attached to the distal end. This combination maintains the functional effectiveness of each tool while eliminating the time loss associated with removing and replacing instruments during surgery
3Productivity
If the forceps design is enhanced with additional features (suction ports, dissecting tip), then the need for instrument exchange is reduced, but the device complexity increases
Solution Approach 1:
The patent applies the nesting principle by integrating the suction hose connection and flow path within the forceps structure. The suction ports are incorporated into the forceps shaft, and the suction hose connects to the forceps handle, nesting the suction system within the existing forceps framework. The micro-hook blunt dissecting tip is attached to the distal end of the forceps, nesting the dissection function within the forceps structure, thereby reducing overall system complexity compared to using separate instruments

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables surgeons to maintain the microanastomosis forceps within the operating field, reducing the need for instrument exchange and enhancing procedural efficiency and precision.
Implementation Method 1
A flow path can be operably arranged between the suction hose and the one or more suction ports

AI summary
A microanastomosis forceps including two longitudinally extending arms extending from a proximal pivot point. Each of the two longitudinally extending arms extends a predetermined length from the proximal pivot point to a respective distal end. A suction hose connection point adjacent to the proximal pivot point and one or more suction ports arranged on the distal end of at least one of the two longitudinally extending arms. A flow path is operably arranged between the suction hose and the one or more suction ports.
