Forceps With Trocar Tip For Anvil Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical techniques face challenges in manipulating surgical stapler anvils within the body, particularly during laparoscopic procedures, due to limited access and visibility, often requiring multiple incisions and risking tissue damage.
Innovation Solution
A forceps with a trocar tip is developed to penetrate tissues and retrieve the anvil of a surgical stapler apparatus, allowing for easier docking and visualization, reducing the number of devices needed and minimizing tissue damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional forceps are used to manipulate surgical stapler anvils during laparoscopic procedures, then the surgeon can attempt to grasp and dock the anvil, but the limited access and visibility cause difficulty in manipulation and increase the risk of tissue damage
Solution Approach 1:
The patent combines a trocar tip with forceps to create a single integrated instrument that can both penetrate tissue and grasp the anvil. This merging of functions eliminates the need for separate instruments, reducing the number of incisions required and minimizing tissue trauma while maintaining ease of anvil manipulation during laparoscopic procedures
Solution Approach 2:
The forceps with trocar tip serves multiple functions: it can penetrate tissue to access the anvil, grasp and manipulate the anvil, and facilitate docking. This multi-functional design addresses the limitation of traditional forceps that can only grasp, thereby improving ease of operation while reducing the need for additional instruments and incisions
2Ease of operation
If multiple incisions are made to access the anvil for docking, then the surgeon can manipulate the anvil more easily, but the number of incisions increases and tissue damage increases
Solution Approach 1:
By combining the trocar's tissue-penetration capability with the forceps' grasping function in a single instrument, the patent enables access to and manipulation of the anvil through a single incision. This eliminates the need for multiple incisions that would otherwise be required to both access and manipulate the anvil, thereby reducing tissue trauma while maintaining ease of operation
Solution Approach 2:
The multi-functional forceps with trocar tip can both create access through tissue penetration and manipulate the anvil through grasping, all through a single incision. This universal instrument design reduces the number of incisions required compared to using separate instruments, thereby minimizing tissue trauma
3Adaptability or versatility
If traditional forceps without trocar tip are used, then the structure remains simple, but the ability to penetrate tissue and retrieve anvil is insufficient
Solution Approach 1:
The patent merges the trocar tip with the forceps structure to create an integrated instrument that possesses both tissue-penetration and grasping capabilities. This combination enhances adaptability and versatility without requiring entirely separate instruments, while the integration is designed to minimize the increase in device complexity
