Description

Dual-blade radiofrequency surgical electrode

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a radio frequency surgical electrode with double blade heads.

Background Art

Radiofrequency surgical electrodes can perform multiple functions such as cutting, perforating, ablation, shrinking and hemostasis of tissues at the cost of "minimally invasive" and have been widely used in clinical practice, especially in otolaryngology departments, such as laryngeal tumor resection, tonsillectomy and adenoids resection, resection, ablation and hemostasis.

Commonly used radiofrequency surgical electrodes are usually only equipped with one electrode blade. When performing spinal surgery and other surgeries, if the area of the lesion is large, only one electrode blade is used for the surgery, resulting in a smaller contact area with the lesion tissue. This will not only increase the patient's pain, but also extend the operation time and reduce the efficiency of the operation.

Commonly used radiofrequency surgical electrodes are usually only equipped with one electrode blade. When performing spinal surgery and other surgeries, if the area of the lesion is large, only one electrode blade is used for the surgery, resulting in a smaller contact area with the lesion tissue. This will not only increase the patient's pain, but also extend the operation time and reduce the efficiency of the operation.

Based on this, the utility model proposes a double-blade radiofrequency surgical electrode. In order to improve the surgical efficiency of the radiofrequency surgical electrode on a larger area of diseased tissue, a first blade head assembly and a second blade head assembly are provided in the double-blade radiofrequency surgical electrode. Through the synergistic effect of the two blade head assemblies, the contact area between the blade head and the diseased tissue can be increased, thereby effectively reducing the operation time.
