Embodiment Construction

[0021] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0022] like figure 1 , 2 As shown, an energy-carrying surgical tool includes a body, the body has an active part in contact with the tissue to be operated, and the surface of the active part is provided with a cermet coating.

[0023] By providing a cermet coating on the surface of the active part of the energy-carrying surgical knife, it has a lubricating effect, thereby greatly reducing scab and adhesion of soft tissues on the surgical knife, and reducing damage caused by adhesion.

[0024] like figure 1 , 2 As shown, the ontology includes:

[0025] tube body 1;

[0026] Fixing part 2, the head of described fixing part 2 is provided with first conductive cutter head 21, and the surface of the remaining part except first conductive cutter hea...

Abstract

The invention discloses an energy-carrying surgical tool. The energy-carrying surgical tool comprises a body, the body has a service portion which is in contact with a surgical organization, and the surface of the service portion is provided with a metal ceramic coating. According to the energy-carrying surgical tool, the tissue adhesion problem during the cutting and clotting processes in an operation can be effectively solved, and an achievement ratio of the operation can be increased.

Description

technical field [0001] The invention relates to an energy-carrying surgical knife, which belongs to the technical field of medical instruments. Background technique [0002] At present, energy-carrying surgical knives are mainly used for soft tissue cutting, hemostasis, and energy generating tools such as radio frequency power supply to output energy signals to surgical knives such as monopolar electric knife, bipolar electrocoagulation forceps, electric pencil, and ultrasonic knife, thereby generating arcs and heat. Perform tissue cutting and coagulation at the contact site. Due to its characteristics of less trauma, less pain, and faster recovery, electrosurgical surgery has become a new trend in surgery. [0003] However, a large amount of heat energy will be generated during the operation, which makes the surgical knife have a very high temperature. When the high-temperature surgical knife comes into contact with soft tissue, it will produce blood coagulation and cuttin...
