Bendable ultrasonic scalpel

Abstract

The invention provides a bendable ultrasonic scalpel which comprises a main machine, a transduction device, a connecting rod driving air cylinder, a connecting rod and a bending scalpel head, the main machine is electrically connected with the transduction device, the connecting rod comprises a first connecting rod and a second connecting rod, the output end of the transduction device is connected with a first rotating component, the side, deviating from the output end of the transduction device, of the first rotating component is connected with the first connecting rod, the main machine provides a stable ultrasonic frequency electric signal, the transduction device converts the ultrasonic frequency electric signal into mechanical vibration, the connecting rod transmits the mechanical vibration to the bending scalpel head, so that the vibration cutting function of the bendable ultrasonic scalpel is achieved, and through the arrangement of the bending scalpel head, the first connecting rod and the second connecting rod, the bendable ultrasonic scalpel has higher operation flexibility, so that a doctor can more accurately cut a focus part of a patient in a minimally invasive laparoscopic surgery, and the success rate of the surgery is greatly increased.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a bendable ultrasonic knife. Background technique [0002] Ultrasonic scalpel is a high-frequency electrosurgical device, mainly used for cutting biological tissues and closing blood vessels. It has the characteristics of less bleeding, less damage to surrounding tissues, and quick postoperative recovery. It acts on human tissue to cut and coagulate, and will not cause side effects such as tissue dryness and burns. There is no current when the bent knife head works Through the human body, it is widely used in the operating room. It is known as the bloodless scalpel. The existing surgical resection mainly uses laparoscopic surgery. Due to the limitation of its own structure, the current ultrasonic scalpel cannot be bent due to its own structure. , When dealing with some special angles of cutting, such as the side and rear of the organs, doctors often cannot find a suitable angl...
