[0033] When the ultrasonic imaging thoracoabdominal laparoscope is used, firstly, an external fixing tube is punctured in the abdomen of the patient, and then the medical staff inserts the endoscope tube 5 into the interior of the external fixing tube, wherein the endoscope tube 5 slides inside the external fixing tube, so that the endoscope tube 5 enters the abdominal cavity of the patient. After the endoscope tube 5 enters the abdominal cavity, the medical staff connects the illumination device to the light inlet mechanism 3, and the light enters the interior of the light conversion mechanism 4 through the light inlet tube. When the light enters the interior of the light conversion mechanism 4, due to the direct light, after the light contacts the reflector 42, it is reflected and deflected to the downward direction and directly irradiates the interior of the endoscope tube 5, and the light After passing through the endoscope tube 5, the wire passes through the convex lens 52, the concave lens 53 and the protective mirror 54 at the lower end of the endoscope tube 5 in sequence, and irradiates the inside of the patient's abdominal cavity.

The up and down movement of 513 realizes the telescopic function of the ultrasound probe, and touches the detection area under the visual condition of the thoracoscopic laparoscope, and performs the Doppler ultrasound function, which can detect the blood flow velocity, blood flow direction, and two-dimensional structure of the near area, distinguish the fascia, blood vessels and deep tissue structures, and retain images to retain objective imaging evidence for the surgeon during the operation. When the ultrasound probe 513 moves up and down, the upper end of the ultrasound probe cable 55 slides on the first steering guide wheel 56, wherein the medical staff can observe the situation inside the patient's abdominal cavity through the eyepiece 1, or receive the information of the ultrasound probe 513 through an external display device.
