====== Surgical sealer ======

Certainly. Let's discuss sealers in the context of surgical instruments more broadly:

1. Definition:
A surgical sealer is a device used to join, close, or seal tissue during surgical procedures. The primary goal is to achieve hemostasis (stop bleeding) and create a secure closure of vessels, tissue planes, or organs.

===== Types of sealers =====

Energy-based sealers

[[Bipolar sealer]]s 

Ultrasonic sealers

Laser sealers
----

====  Mechanical sealers ====

Surgical staplers

Clips

==== Chemical sealers ====

Fibrin sealants

Synthetic surgical adhesives

3. Common applications:
   - Vascular surgery: Sealing blood vessels
   - Thoracic surgery: Sealing air leaks in lung tissue
   - Gastrointestinal surgery: Joining sections of intestine
   - General surgery: Sealing lymphatics, small blood vessels
   - Neurosurgery: Dural sealing

4. Key features of modern sealers:
   - Precision application
   - Reduced collateral tissue damage
   - Ability to work on various tissue types
   - Integration with other surgical techniques

5. Benefits:
   - Potentially faster procedures
   - Reduced blood loss
   - Lower risk of post-operative complications in some cases
   - May reduce the need for sutures or staples in certain procedures

6. Considerations:
   - Different tissue types and surgical sites may require specific sealer types
   - Proper training is essential for effective use
   - Cost can be a factor, especially for advanced energy-based systems

7. Recent developments:
   - Integration of sensing technologies to adjust sealing parameters automatically
   - Combination devices that can seal, cut, and dissect
   - Development of biocompatible and absorbable sealing materials

8. Regulatory aspects:
   - Surgical sealers, especially those using energy or new materials, typically undergo rigorous testing and approval processes by regulatory bodies like the FDA.
