Peritoneal Cavity Simulator Model Gripping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical simulators face challenges in easily exchanging biologically textured organ models during training, particularly in reproducing the pelvis structure and urinary bladder area, which hampers realistic training and instrument positioning.
Innovation Solution
A peritoneal cavity simulator with a biologically textured organ model and a model gripping portion, featuring a casing that simulates a human body shape with multiple ports and a model gripping mechanism for secure placement, allowing easy exchange and realistic simulation of laparoscopic procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If forceps and surgical instruments are inserted from multiple ports simultaneously, then the training of laparoscopic procedures becomes more realistic, but the exchange of intraperitoneal organs such as urinary bladder becomes difficult due to the time required for extraction and insertion of instruments
Solution Approach 1:
The simulator is divided into separate functional modules: the casing with ports, the model gripping portion, and the biologically textured organ models. This segmentation allows the organ models to be independently exchanged without requiring removal of the forceps and surgical instruments that remain inserted in the ports, thus maintaining training realism while facilitating easy model replacement.
Solution Approach 2:
The model gripping portion is designed to extract and hold the biologically textured organ models separately from the surgical instruments. This extraction mechanism allows the organ models to be removed and replaced independently, solving the problem where instrument presence previously made model exchange difficult.
2Adaptability or versatility
If conventional simulators are used for training suturing of urinary bladder area with urine duct, then basic laparoscopic skills can be practiced, but the positioning of insert materials simulating human tissue requires manual adjustment and repeated training is cumbersome
Solution Approach 1:
The model gripping portion is pre-configured with positioning structures that automatically locate and secure the biologically textured organ models in the correct positions within the casing. This preliminary positioning action eliminates the need for manual adjustment during training, allowing practitioners to immediately begin suturing exercises without time-consuming setup.
Solution Approach 2:
The model gripping portion performs self-positioning through its structural design, automatically orienting and securing the organ models without requiring external manual intervention. This self-service capability ensures consistent, accurate positioning for each training session, eliminating repetitive adjustment time while maintaining training versatility.

AI summary
Provided is a peritoneal cavity simulator that can simplify the execution of alignment during the replacement of living-body-feeling model organs for repeated trainings on a simulator for peritoneal cavity microscopic surgery. This peritoneal cavity simulator comprises: a casing that has a pelvis part, a back part, and an abdomen part; living-body-feeling model organs; and a model holding part. The casing simulates a pelvis and a peritoneal cavity space and comprises at least the pelvis part, which simulates the shape of a human body, the back part, which has left and right flank parts, and the abdomen part, which is provided with a plurality of ports into which can be inserted a surgical instrument that is used in peritoneal cavity microscopic surgery. The model holding part is a holding part that is attached to the back part or the pelvis part, and fixes, mounts, or sandwiches and holds the living-body-feeling model organs inside the peritoneal cavity space. For training in the suturing of a model bladder (10) and a urethra tube (4), a belt-like member (11) that contacts an inner wall of a casing (2) of the pelvis part is provided to the model bladder (4), and the model bladder (10) can be taken in and out of the peritoneal cavity space by means of the belt-like member (11).
