The invention provides a cervical cone type radio frequency ultrasonic knife with radio frequency and ultrasonic dual energy, and belongs to the technical field of medical instruments, the cervical cone type radio frequency ultrasonic knife comprises a rod body, the rod body comprises a straight section, a first arc-shaped bending section, a second arc-shaped bending section and an inclined knife head which are continuously arranged; one end, far away from the first arc-shaped bent section, of the straight section is detachably connected with the transducer; the first arc-shaped bent section is bent in an arc shape in the direction far away from the axis of the straight section, the second arc-shaped bent section is bent in an arc shape in the direction close to the axis of the straight section, and the tangent line of the second end, connected with the second arc-shaped bent section, in the first arc-shaped bent section and the tangent line of the third end, connected with the first arc-shaped bent section, in the second arc-shaped bent section are collinear. By means of the mode, the radio frequency ultrasonic knife can integrate dual energy of radio frequency and ultrasound and is applied to cervical conization, operation of the surgery is simplified, and heat damage to tissue can be effectively reduced while cutting efficiency is guaranteed.

This invention provides a cervical conical radiofrequency ultrasonic scalpel with dual radiofrequency and ultrasound energy, belonging to the field of medical device technology. The cervical conical radiofrequency ultrasonic scalpel includes a shaft comprising a continuously arranged straight section, a first arc-shaped bending section, a second arc-shaped bending section, and an inclined cutting head. The end of the straight section away from the first arc-shaped bending section is detachably connected to a transducer. The first arc-shaped bending section is curved away from the axis of the straight section, and the second arc-shaped bending section is curved towards the axis of the straight section. The tangent at the second end of the first arc-shaped bending section connected to the second arc-shaped bending section is collinear with the tangent at the third end of the second arc-shaped bending section connected to the first arc-shaped bending section. Through this method, the radiofrequency ultrasonic scalpel provided by this invention can integrate both radiofrequency and ultrasound energy and be applied to cervical conization, simplifying the surgical procedure and effectively reducing thermal damage to tissues while ensuring cutting efficiency.
