Abstract

The present application discloses a surgical instrument, including a steering joint, an operating body, an actuator and a traction unit; the steering joint is provided with a first steering area and a second steering area, which are pivotally connected and can be pivoted around a first axis or a second steering area. The two axes are deflected; the first turning area has a first turning section, the traction unit includes a first pulling rope assembly and a second pulling rope assembly, the first pulling rope assembly is respectively connected with the operating body and the first turning section, and the first turning section can be Deflecting around the first axis and / or the second axis; the second steering area has a second steering segment, the second traction rope assembly is respectively connected with the operating body and the second steering segment, and the second steering segment can be around the first axis and / or The second axis is deflected. The two steering areas are deflected respectively. When one of the steering areas reaches the deflection limit and still cannot reach the surgical site, the medical staff can control the deflection of the other steering area and finally reach the surgical site without adjusting the overall position of the surgical instruments. the overall range of movement.

Description

technical field

[0001] The application belongs to the technical field of medical devices, and specifically relates to a surgical instrument. Background technique

[0002] In small-diameter operations such as single-hole surgery and minimally invasive surgery, in order to reduce the diameter of the opening in the human body, doctors often use slender surgical instruments to insert into the human body to perform the operation. However, traditional surgical instruments have limited degrees of freedom, cannot achieve pitch and yaw motion, and are relatively clumsy. Therefore, medical staff need to frequently adjust the position of surgical instruments during the operation, 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 end portion, and a dis...
