Surgical Grasper with Integrated Tissue Probe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laparoscopic surgery often requires multiple access ports for instrumentation, which can complicate procedures and limit the use of additional instruments within the body cavity, and there is a need to investigate or treat tissue without additional port access.
Innovation Solution
A surgical instrument with a handle, elongated body, and end effector with movable jaws that integrate a probe for tissue manipulation, illumination, visualization, and diagnosis, allowing the probe to move between retracted and advanced positions automatically with jaw closure, reducing the need for multiple ports and enhancing tissue examination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple access ports are used for laparoscopic instrumentation, then more instruments can be introduced into the body cavity, but the procedure complexity increases and patient recovery time extends
Solution Approach 1:
The patent combines multiple functional instruments into a single integrated laparoscopic instrument. The instrument integrates a grasping mechanism with a separate lumen for introducing additional instruments or probes into the body cavity, allowing multiple functions to be performed through a single access port rather than requiring multiple separate ports and instruments
2Adaptability or versatility
If multiple access ports are used for laparoscopic instrumentation, then more instruments can be introduced into the body cavity, but the number of incisions and patient trauma increases
Solution Approach 1:
The patent combines multiple functional instruments into a single integrated laparoscopic instrument. The instrument integrates a grasping mechanism with a separate lumen for introducing additional instruments or probes into the body cavity, allowing multiple functions to be performed through a single access port rather than requiring multiple separate ports and instruments
3Measurement precision
If tissue investigation requires additional port access, then diagnostic accuracy improves, but procedure time and complexity increase
Solution Approach 1:
The patent integrates a diagnostic probe delivery system within the grasping instrument. A separate lumen allows introduction of a probe that can be advanced through the instrument body to contact and investigate tissue directly at the grasp site, eliminating the need for additional ports and reducing procedure time while maintaining diagnostic accuracy
4Object-affected harmful factors
If a single access port is used, then patient trauma is reduced, but instrument maneuverability and functionality are limited
Solution Approach 1:
The patent employs a nested structure where a diagnostic probe or additional instrument is introduced through a separate lumen within the main instrument body. This allows the probe to be nested within the grasping instrument during insertion, then advanced independently to the tissue site, providing enhanced functionality through a single access port
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 minimally invasive procedures with reduced port requirements, allowing for tissue grasping, illumination, imaging, and treatment through a single port, while maintaining instrument maneuverability and providing diagnostic capabilities within the body cavity.
Implementation Method 1
The sheath in some embodiments can include a camming member(s) engageable with a camming slot of the end effector to move the end effector between the first and second positions
Data Source
AI summary
A surgical instrument for minimally invasive surgical procedures having a handle portion, an elongated body portion extending distally from the handle portion, an end effector movable between a first position and a second position, and an elongated tissue probe movably positioned within the elongated portion. The probe is movable between a retracted position and an advanced position, wherein movement of the probe moves the end effector from the first position to the second position.
