Abstract

The invention discloses a surgical instrument. The surgical instrument comprises a steering knuckle, an operation main body, an execution piece and a traction unit; the steering knuckle is provided with a first steering area and a second steering area which are connected in a pivoted mode and can deflect around a first axis or a second axis. The first steering area is provided with a first steering section, the traction unit comprises a first traction rope assembly and a second traction rope assembly, the first traction rope assembly is connected with the operation body and the first steering section, and the first steering section can deflect around a first axis and / or a second axis; the second steering area is provided with a second steering section, the second traction rope assembly is connected with the operation body and the second steering section, and the second steering section can deflect around the first axis and / or the second axis. The two steering areas deflect respectively, when one steering area reaches the deflection limit and still cannot reach the surgical site, medical staff can control the other steering area to deflect and finally reach the surgical site, the overall position of the surgical instrument does not need to be adjusted, and the overall moving range is reduced.

Description

technical field [0001] The application belongs to the technical field of medical devices, and in particular relates to a surgical device. Background technique [0002] In small-diameter operations such as single-hole surgery and minimally invasive surgery, in order to reduce the caliber of the opening in the human body, doctors often use elongated surgical instruments to extend into the human body to perform the operation. However, traditional surgical instruments have limited degrees of freedom, cannot achieve pitch and yaw movements, and are relatively clumsy. Therefore, during the operation, medical staff need to frequently adjust the position of surgical instruments, which not only aggravates the fatigue of medical staff, but also affects the operation. quality and precision. [0003] Chinese patent CN109475271A discloses a steerable instrument comprising a cylindrical diameter-adapting section, comprising an elongated tubular body having a proximal portion, and a dista...
