Abstract

The invention relates to a intracavitary operation tool. The intracavitary operation tool comprises an imaging tool, an operation tool, a mirror body, an imaging tool driving mechanism and an operation tool driving mechanism, wherein the imaging tool comprises a camera and an imaging tool arm body; the camera is connected to an imaging tool arm body far end; an imaging tool arm body near end is connected with the imaging tool driving mechanism; the operation tool comprises an execution mechanism and an operation tool arm body; the execution mechanism is connected to an operation tool arm bodyfar end; the execution mechanism penetrates through an inner cavity channel of the operation tool arm body and then is linked with the operation tool driving mechanism; an operation tool arm body nearend is also linked with the operation tool driving mechanism; the mirror body comprises an imaging guide pipe, an operation guide pipe and a dispersion supporting body; the imaging guide pipe and theoperation guide pipe are used for guiding and restricting the imaging tool arm body and the operation tool arm body, so that the camera and the execution mechanism reach the same region at the far ends; meanwhile, the imaging tool driving mechanism and the operation tool driving mechanism have an enough space for arrangement at the near ends.

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...
