Cutter bar for ultrasonic scalpel and ultrasonic scalpel

Abstract

The invention provides a cutter bar for an ultrasonic scalpel and the ultrasonic scalpel, and belongs to the technical field of minimally invasive surgical instruments, the cutter bar for the ultrasonic scalpel is characterized in that the front end of the cutter bar is arc-shaped, and the cutter bar comprises a cutter bar body; an outer sleeve; a jaw assembly; a sliding block; a steel wire rope; and a limiting structure used for limiting the steel wire rope to deviate in the radial direction is arranged in the outer sleeve. According to the cutter bar for the ultrasonic scalpel, the front end of the cutter bar is in an arc shape, a natural cavity of a human body is mostly of a curve structure and is complex in shape, a cutter bar of a traditional ultrasonic scalpel is of a rigid linear structure and is difficult to enter the cavity of the human body, and even if the cutter bar enters the cavity, due to the limited physiological structure and bearing capacity of a patient, the moving area of a front cutter head is small, after the front cutter head enters the human body, the arc-shaped cutter bar obtains a larger operation range when rotating along the axis of the arc-shaped cutter bar relative to the cutter bar of the linear structure at the same moving included angle, the operation intensity of an operator is reduced, and the pain degree of a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of minimally invasive surgical instruments, in particular to a knife rod for an ultrasonic scalpel and the ultrasonic scalpel. Background technique [0002] Ultrasonic scalpel refers to focusing high-intensity ultrasound on the tip of the knife through the horn. The strong vibration of the knife is used to remove tumors in human soft tissues. Ultrasonic energy is used to treat soft tissues, which can complete cutting and coagulation at the same time, and can ensure minimum tissue lateral thermal injury. Intended for cutting soft tissue where bleeding control and minimal thermal damage are required. Ultrasonic scalpels are essential surgical instruments in various minimally invasive surgeries. With the popularity of minimally invasive surgery, ultrasonic scalpel has become a routine surgical instrument. [0003] In the prior art, the ultrasonic scalpel includes a handle, a knife rod and a cutter head; wher...
