Embodiment Construction
[0023] The technical solution of the present invention will be described in detail below in combination with the embodiments and the accompanying drawings.
[0024] Such as Figure 1 to Figure 6 As shown, a structure of an intracavity surgical manipulator is designed, including a negative pressure tube 1, a sleeve 2, an instrument rod 3, a slider 4, a restraint tube 5, an elastic wire 6, an endoscope 7, and an endoscope holder 8 .
[0025] Such as figure 1 As shown, the elastic wire 6 is pre-bent into a specific shape, which can be a curved shape such as a circular arc, and when the elastic wire 6 extends out of the restraint tube 5, it can return to the pre-bent shape, so as to realize the endoscope 7 during the operation. The function of turning a certain angle.
[0026] Such as figure 1 As shown, the negative pressure tube 1 is pre-bent into a specific shape, which can be a curved shape such as a circular arc, and can restore the pre-bent shape after the negative pressu...

The invention discloses an intracavity surgery operator. The intracavity surgery operator comprises a negative-pressure tube, a casing, an instrument rod, a slider, limit tubes, elastic wires, an endoscope and an endoscope seat. The instrument rod is provided with four channels inside, including a casing channel, limit tube channels and an endoscope data line channel. The casing is arranged in the casing channel and penetrates the integral casing channel. The negative-pressure tube is arranged in the casing with two ends extending out of the casing respectively. The limit tubes are arranged in the limit tube channels respectively, one end of each limit tube extends from the end of the instrument rod and the other end of each limit tube extends out of the middle of the instrument rod to be fixedly connected with the slider. The elastic wires are arranged in the limit tubes, one ends of the elastic wires extend out of the ends of the limit tubes connected with the slider and are fixedly connected at the end of the instrument rod, the other ends of the elastic wires extend out of the other ends of the limit tubes and are fixedly connected with the endoscope seat. The lens part of the endoscope is arranged in the endoscope seat, the data line of the endoscope penetrates the endoscope data line channel in the instrument rod and out of the channel.
Description
technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to an intracavitary operation manipulator. Background technique [0002] Since the 20th century, as people have put forward higher and higher requirements for the diagnosis and treatment of their own diseases, especially the formation and development of minimally invasive surgery, the medical community has proposed that the so-called minimally invasive surgery should have the characteristics of small surgical trauma, light scars, and fast recovery. With the advancement of robot technology and related disciplines, a group of minimally invasive surgical robots that can replace surgeons to varying degrees have emerged, and it has become a reality to use surgical robots to complete minimally invasive surgery. [0003] In 1995, Frederick established Intuitive Surgical in cooperation with NASA and the Stanford Research Institute, and manufactured the "Da Vinci" robotic surge...
