Anatomic Structure Extractor Single Incision Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods for removing intra-abdominal and intrathoracic masses or organs require multiple incisions, leading to complications such as wound infection, incisional hernia, and the need for general or spinal anesthesia, which carries risks like myocardial infarction and stroke.
Innovation Solution
An anatomic structure extractor device with a tubular member, cap, trap, suction post, and light post, allowing for the insertion, visualization, aspiration, and removal of cystic and solid masses through a single limited incision without the need for abdominal or chest wall retraction and general/spinal anesthesia, using a corkscrew needle and morcellizing auger for material extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple puncture incisions are made for laparoscopic surgery, then exposure for surgeon visualization and manipulation is improved, but the risk of wound infection, incisional hernia, and other complications increases
Solution Approach 1:
The device segments the surgical approach by using a single incision site with multiple functional ports (view port, needle port, suction port) integrated into one extractor assembly, eliminating the need for multiple separate incisions while maintaining all necessary surgical functions
Solution Approach 2:
The device merges multiple surgical functions (visualization through view port, tissue manipulation through needle port, and fluid evacuation through suction port) into a single integrated extractor assembly that accesses the body through one incision, combining what traditionally required multiple separate access points
2Ease of operation
If abdominal wall retraction or gas insufflation is performed, then surgical exposure is improved, but the need for general or high-spinal anesthesia increases, carrying risks of myocardial infarction, stroke, and other serious complications
Solution Approach 1:
The device extracts the need for general or spinal anesthesia by enabling the surgical procedure to be performed through a single small incision with direct visualization and manual manipulation, eliminating the requirement for abdominal wall retraction or gas insufflation that would otherwise necessitate anesthesia
Solution Approach 2:
The tubular extractor assembly acts as an intermediary tool that provides direct access to intra-abdominal structures through a single small incision, serving as a mediator that eliminates the need for complex anesthesia and wall retraction maneuvers by allowing direct visualization and manipulation through the tube
3Object-affected harmful factors
If a single limited incision is used, then the risk of anesthesia-related complications and wound complications is reduced, but the ability to visualize and manipulate tissue is limited
Solution Approach 1:
The extractor assembly is designed as a universal multi-functional device with a view port for visualization, a needle port for tissue manipulation and biopsy, a suction port for fluid evacuation, and a trap for material collection, all integrated into a single assembly that provides comprehensive surgical capability through one incision
Solution Approach 2:
The device adds dimensional capability by incorporating a longitudinal trap within the tubular structure that extends along the length of the extractor, providing a three-dimensional workspace for material collection and manipulation that overcomes the limitations of a single small incision opening

AI summary
An anatomic structure extractor allows a medical practitioner to retract, aspirate, ligate and amputate an anatomic structure within a patient through a minimally invasive incision. An anatomic structure extractor may include a transparent tubular member with a cap coupled to one end. The cap may have at least one view port with a magnifying lens. The cap may also have a needle port through which a needle is inserted to puncture the anatomic structure. A trap may be in fluid communication with the transparent tubular member. A suction post is in communication with the trap to pull the contents of an aspirated cyst into the trap. A light post containing a light source may be connected to the transparent tubular member to illuminate the interior of the extractor. A ligature deployer and a cutting wire may also be coupled to the tubular member.
