Electrosurgery and surgical diathermy involve the use of high-frequency A.C. electric current in surgery as either a cutting modality, or else to cauterize small blood vessels to stop bleeding. This technique induces localized tissue burning and damage, the zone of which is controlled by the frequency and power of the device.

Diathermy is frequently used to coagulate a bleeding vessel or to cut tissues. Unipolar diathermy is commonly used. As the current frequency increases above 100 kHz (i.e. radiofrequency), the entire effect is heat generating. Components

Next, reduce diathermy power and approach the bleeding site, making gentle contact to achieve cauterization. Using the minimum amount of diathermy necessary can help avoid collateral damage to the retina, which can result in atrophic holes, and to large vessels, which can result in vascular occlusions and ischemia.

The heat generated by diathermy can destroy tumors and infected tissues along the urinary tract or male reproductive system, and can cauterize blood vessels to inhibit excessive bleeding. Electric currents are generated by the movement of electrons.

2023年8月16日 · Precision: Surgical diathermy provides precise cutting and coagulation, enabling surgeons to target specific tissues with minimal damage to surrounding areas. Hemostasis: Diathermy's ability to coagulate blood vessels during surgery helps control bleeding, reducing the risk of excessive blood loss.

1994年10月3日 · Electrosurgery (ES), also called surgical diathermy, is a method applied during surgical procedures for cutting tissue and coagulating small blood vessels with the advantage of diminished...

2022年3月1日 · We have been managing our A-T patient's bladder telangiectasia for 1 year, and have utilised cystoscopic diathermy as our mainstay of treatment, firstly as it served as a relatively fast, definitive and conservative surgical method to allay life-threatening intravesical bleeding and stabilise our severely anaemic patient, and secondly because ...

Electrosurgery and surgical diathermy involve the use of high-frequency A.C. electric current in surgery as either a cutting modality, or else to cauterize small blood vessels to stop bleeding. This technique induces localized tissue burning and damage, the zone of which is controlled by the frequency and power of the device.

2002年5月1日 · Surgical diathermy is an important tool for arresting bleeding from small vessels and for cutting tissues whilst maintaining haemostasis. Although haemostasis can be achieved by the application of heat generated and conducted to the tissues by means other than electrical, radio-frequency (RF) diathermy is a convenient, quick and reasonably safe ...

In summary, the Endosaber is a novel needle-type knife with the unique characteristic of a suction function. This distinctive feature may enable us to keep clear visibility in the surgical area even while bleeding is occurring.
