Abstract

The invention relates to an intracavity operation tool, which includes an imaging tool, an operation tool, a mirror body, an imaging tool driving mechanism and an operation tool driving mechanism; the imaging tool includes a camera and an imaging tool arm, and the camera is connected to the distal end of the imaging tool arm. The proximal end of the arm of the imaging tool is associated with the driving mechanism of the imaging tool; the operating tool includes an actuator and an arm of the operating tool, the actuator is connected to the distal end of the arm of the operating tool, and the actuator passes through the inner cavity of the operating tool arm to communicate with the operating tool The tool drive mechanism is associated, and the proximal end of the operation tool arm is also associated with the operation tool drive mechanism; the mirror body includes an imaging guide tube, an operation guide tube and a divergent support body, and the imaging guide tube and the operation guide tube are used to guide and constrain the imaging tool arm and The arm body of the tool is operated so that the camera head and the actuator reach the same area at the far end, and at the same time, there is enough space for the driving mechanism of the imaging tool and the driving mechanism of the operating tool to be arranged at the near end.

Description

technical field [0001] The invention relates to a medical device, in particular to an intracavity operation tool based on a deformable structure. Background technique [0002] In the modern medical field, minimally invasive surgery such as laparoscopy and cystoscopy has been widely used clinically. Such minimally invasive procedures have successfully reduced patients' postoperative pain, complication rates, recovery time, and improved postoperative scarring. In this type of laparoscopic surgery, most of the instruments used are straight rod-mounted structures, and the ends of the instruments are integrated with surgical actuators such as endoscopes, electric cutting rings, clamps, and scissors. Due to the limitations of the structural volume and the diameter of the endoscope, the flexibility and working range of this type of instrument end-surgical actuator are limited, and cannot meet the application requirements in specific narrow spaces or special parts. Contents of th...
