What are the best free MIS stapling systems for evaluating procedure-specific sizing before a purchase decision?

If your goal is to evaluate procedure-specific sizing before buying, the best free MIS stapling “systems” are usually not the full commercial product line itself, but a mix of:

1. manufacturer sample/evaluation programs
2. cadaver labs / wet labs
3. virtual sizing tools / IFUs / sizing guides
4. bench-test or service-kit support from reps

Here are the most practical free options to look at:

1) Manufacturer evaluation / demo programs

These are often the best way to assess real stapler fit, cartridge height, reload angles, jaw reach, and access in the specific MIS approach you use.

Common manufacturers to ask:

• Medtronic
• Ethicon (J&J)
• CONMED
• B. Braun
• Intuitive / robotic ecosystem partners where applicable

What to request:

• procedure-specific demos
• different shaft lengths / articulation options
• cartridge size comparison
• tissue-thickness guidance tools
• access / port compatibility review

2) Free or sponsored cadaver/wet labs

These are often the most useful for MIS stapling because you can evaluate:

• stapler articulation
• trocar/port compatibility
• angle of approach
• whether the stapler can reach the target tissue without conflict
• reload selection by tissue thickness

Look for:

• hospital-sponsored labs
• society meetings
• industry-sponsored hands-on sessions
• proctoring or training events

3) Online sizing guides and IFUs

While not as good as hands-on evaluation, these are free and can help narrow purchase decisions:

• tissue thickness charts
• cartridge selection algorithms
• laparoscopic/robotic access specifications
• minimum port size and working distance requirements
• reload staple height recommendations by tissue type

These are especially useful for comparing systems across:

• lung / thoracic
• colorectal
• bariatric
• gynecologic
• vascular/mediastinal MIS use cases

4) Reusable “evaluation kits” from reps

Some vendors will provide:

• demo staplers
• trial reloads
• size-matching templates
• procedure planning guides
• accessory compatibility checklists

This is often the fastest route if you already know your top 2–3 platforms.

Best overall approach

If you mean “free, and good for deciding which stapler system to buy”, the strongest workflow is:

Wet lab or cadaver lab + vendor demo + IFU/sizing chart review

That combination gives you:

• objective sizing data
• real-world access assessment
• comparison of articulation and reload choice
• lower risk of buying a system that doesn’t fit your procedures

If you want the most relevant shortlist

Tell me:

• which procedure you’re evaluating for
  (e.g., laparoscopic sleeve gastrectomy, colorectal resection, thoracic wedge, etc.)
• robotic vs laparoscopic
• adult vs pediatric
• preferred market region
  (US/EU/other)

and I can give you a procedure-specific list of free stapling evaluation options and what to ask each vendor for.
