Ultrasonic cutting equipment uses high-frequency ultrasonic vibration to cut soft tissue, and at the same time coagulates small blood vessels through the heat generated by vibration to achieve hemostasis. Different types of soft tissues may respond and respond differently to ultrasonic cutting equipment due to differences in their structure and composition. Here are some of the possible influences and differences
Ultrasonic cutting equipment uses high-frequency ultrasonic vibration to cut soft tissue, and at the same time coagulates small blood vessels through the heat generated by vibration to achieve hemostasis. Different types of soft tissues may respond and respond differently to ultrasonic cutting equipment due to differences in their structure and composition. Here are some of the possible factors and differences:
Tissue density:
More dense tissues, such as bone, cartilage, and thicker muscles, may require higher ultrasonic energy to cut.
Loose tissue, such as fat and certain types of tumors, may be more susceptible to ultrasound cutting.
Tissue water content:
Tissues with high water content, such as liver and brain tissue, are usually more susceptible to ultrasound cutting because water helps the propagation of ultrasound and the transfer of energy.
Dry or fibrotic tissue, such as scar tissue, may be more resistant to ultrasonic dissection.
Vascular richness:
Vascular-rich tissue may require more careful hemostasis during cutting, and ultrasound equipment can cut and coagulate small blood vessels at the same time, reducing intraoperative bleeding.
Less vascularized tissue may be less demanding for hemostasis during the cutting process.
Tissue thickness:
Thicker tissue may require longer sonication to completely cut.
Thin tissue may require faster cutting speeds and lower energy settings because of the risk of thermal damage.
Tissue toughness:
Toughness tissues, such as fascia and ligaments, may require higher ultrasound frequency and power to cut.
Tissues with low toughness, such as serosa, may be more susceptible to ultrasonic cutting.
Inflammation and infection:
Inflammation or infection of the tissue may be due to local edema and inflammatory cell infiltration and affect the effect of ultrasonic cutting.
Operation environment:
The fluid environment (such as blood, saline) during the operation may affect the propagation and cutting effect of ultrasound.
Because of these differences, surgeons need to adjust the device settings, such as power, frequency, and cutting speed, according to different tissue types when using ultrasonic cutting devices to achieve cutting effects and minimal tissue damage. In addition, the accumulation of surgical experience and in-depth understanding of the principles of ultrasonic cutting are also key factors to ensure the success of surgery.
