Harmonic scalpel
The harmonic scalpel uses high-frequency ultrasound energy to cut tissue and seal blood vessels. The scalpel’s surface vibrates at 55,500 Hz, which creates friction and stress in the tissue’s molecules. This friction generates heat, which denatures the tissue’s proteins. The denatured proteins then seal blood vessels and coapt tissue. The scalpel’s design also helps to couple the ultrasonic energy with the tissue. For example, the hook blade’s large outer radius and flat blade sides allow for coagulation and coaptation without cutting or boring into soft tissues. The scalpel also has a ball coagulator that can be used to coagulate surfaces.
The harmonic scalpel’s high-frequency vibration minimizes the amount of energy that’s transferred to the surrounding tissue, which can help to limit collateral damage. The scalpel was developed in the early 1990s as an alternative to other methods of controlling blood vessels. It’s typically made up of a hand-held ultrasonic transducer, generator, hand switch, foot pedal, and the scalpel itself.
Suture Tor for vascular anatomists
Non absorbable monofilament round tip
Use of bogota bag
Visualize visceral condition and viability before anastomosis
#A Bogota bag is a sterile plastic bag used to temporarily close abdominal wounds after surgery. It’s often used when primary closure isn’t possible or other techniques aren’t available. The bag is typically a 3-liter genitourinary irrigation bag that’s sewn to the skin or fascia of the anterior abdominal wall. The bag allows the peritoneal viscera to expand, which prevents increased intra-abdominal pressure. It also provides a window for inspecting the contents of the abdomen.
Disadvantage of should sutures
Polyfilament (prone to infection)
Non absorbable
Though cheap
Suture for scrotal skin of children
The main difference between the two sutures is the rate of absorption: Vicryl Rapide® is irradiated and hence is absorbed much more quickly than Vicryl®. Vicryl® has 75% of its original breaking strength at 14 days and 50% at 21 days. In contrast, Vicryl Rapide® has 50% at 5 days and almost none at 14 days.
