With its low-profile design, this component reduces instrument collisions, while still accommodating 5–12mm laparoscopic tools.
What are Self-Retaining Sleeves?
How many liters of blood does the average human heart pump in one day?
Reasoning: Cardiac output ≈ 5 L/min (typical).
5 L/min × 60 min/hr = 300 L/hr.
300 L/hr × 24 hr/day = 7,200 L/day.
Answer: ≈ 7,200 L/day.
Engineers use this device to apply and measure forces on catheters or instruments, helping determine insertion or deployment forces.

What is The Bird Diaper?
This animated show features a pair of stepbrothers who spend every episode engineering wild inventions, from rollercoasters to time machines.
What is Phineas and Ferb?
In product development, this step ensures a design works as intended and fulfils the needs of all users.
What is Design Validation?
How many 1 mL insulin syringes would it take to fill a standard 2-liter IV fluid bag?
Reasoning: 2 liters = 2000 mL. Each syringe = 1 mL.
2000 mL / 1 mL = 2,000.
Answer: 2,000 syringes.
Engineers use this mathematical method to determine the maximum stress a material can handle before failure.

What is The Anti-Eating Face Mask?
In Pixar’s “Big Hero 6,” this inflatable healthcare robot was designed as a personal medical companion.
Who is Baymax?
This system combines circumferential retraction with a GelSeal™ cap that allows triangulation of laparoscopic instruments, and is known for enabling vNOTES procedures.
What is the GelPOINT V-Path Transvaginal Access Platform?
How many N (Newtons) does a 1 kg mass weigh?
Reasoning: Weight ≈ mass × g; g ≈ 9.81 m/s².
1 × 9.81 = 9.81 N → round ≈ 9.8 N.
Answer: ~9.8 N.
Catheters are often measured by this French-based unit of diameter, equal to 1/3 mm.

What is The Animal Ear Protector?
In “Toy Story 3,” the toys escape the daycare using this type of engineered system.
What is a Conveyor Belt?
This step establishes that an individual process is effective under normal operating conditions and reproducible.
What is Performance Qualification (PQ)?
How long would it take to 3D print a human-sized skeleton if each bone takes ~2 hours?
Reasoning: 206 total bones
206 × 2 = 412 hours
Answer: ~ 17 continuous days
Curved, serrated, or tapered jaws on instruments like Epix Dissectors are tested for this property to ensure tissue is mobilized without slipping.
What is traction/ grip force?

What is The Kissing Shield?
In “WALL-E,” this lonely little robot spends his days compacting this type of human waste into cubes.
What is trash/ garbage?
This term in acceptance sampling defines the worst tolerable process average that can still pass inspection, ensuring lots below it are accepted with high confidence.
What is the Acceptance Quality Limit (AQL)?
If a device prototype takes 4 hours of hands-on assembly, how many workdays would it take to build 30 prototypes (if 1 person is working 8-hour days)?
Reasoning: 30 prototypes × 4 hours = 120 hours.
1 person-day = 8 hours → 120 ÷ 8 = 15 person-days.
Answer: 15 workdays.
This principle describes how fluids exert pressure that is transmitted equally in all direction, allowing devices like hydraulic syringes to work.
