[0025] like Figure 2 , 3 As shown, the endoscopic probe 7 includes a light-conducting hose 71, one end of which is connected to the No. 1 connecting line 5, and the other end is connected to a connecting block 72, and the side of the connecting block 72 away from the light-conducting hose 71 is connected to an operating piece 73, a camera probe 74 and a sensing element 75, and the camera probe 74 and the sensing element 75 are arranged side by side on one side of the operating piece 73.

[0026] The connecting block 72 is used to connect the surgical piece 73, the camera probe 74 and the sensing element 75 to the optical hose 71. The movement of the endoscopic probe 7 is controlled by the control panel 21 on the connecting handle 2. The endoscopic probe 7 can be turned through the optical hose 71 and the position where the endoscopic probe 7 is inserted is illuminated, so as to facilitate the observation of the position to be treated. The camera probe 74 takes a picture of the endoscopic part and transmits it to the display panel 4. When the designated position is reached, the surgical piece 73 performs the operation. The surgical piece 73 is one of a biopsy forceps, an injection needle, a polyp snare, a grasping forceps, a multiple varicose vein ligator, a stenosis dilator, a guide wire, a cyst puncture device, an endoscopic puncture needle, and a mechanical lithotripter. The stenosis dilator or the mechanical lithotripter is a device used for urology surgery. The specific selection of which device to use for the internal surgery depends on the type of surgery, the condition and the judgment of the doctor. The sensing element 75 is a magnetic field generator. After the magnetic field signal generated by the sensing element 75 is received by the point positioning device 8, the specific position of the endoscopic probe 7 inside the human body can be located, so as to facilitate the external auxiliary surgery.

[0027] like Figure 4As shown, the point positioning device 8 includes a connecting frame 81 and a positioning platform 82 arranged in the connecting frame 81. The connecting frame 81 is used to fix the positioning platform 82 and is connected to a position convenient for positioning such as above a hospital bed or a ceiling of a hospital. A transverse moving device 83 is arranged in the connecting frame 81, and a longitudinal moving device 84 is arranged on the positioning platform 82. The power motors of the transverse moving device 83 and the longitudinal moving device 84 are both arranged in the connecting frame 81.

[0028] The transverse moving device 83 includes a No. 1 moving motor 831 and a No. 1 transmission screw 832 connected to the No. 1 moving motor 831, and a No. 1 transmission connecting block 833 is movably connected to the No. 1 transmission screw 832, and the No. 1 transmission connecting block 833 is connected to one end of the longitudinal moving device 84, and the other end of the longitudinal moving device 84 away from the No. 1 transmission connecting block 833 is movably connected to a driven screw 834; the No. 1 moving motor 831 drives the No. 1 transmission screw 832 to rotate, and the No. 1 transmission screw 832 drives the No. 1 transmission connecting block 833 to move along the direction of the No. 1 transmission screw 832 during the rotation, thereby driving the longitudinal moving device 84 to move transversely, and the other end of the longitudinal moving device 84 moves on the driven screw 834.

[0029] The longitudinal moving device 84 includes a No. 2 moving motor 841 connected to one side of the No. 1 transmission connecting block 833 and a No. 2 transmission screw 842 connected to the No. 2 moving motor 841. The two ends of the No. 2 transmission screw 842 are respectively connected to the No. 1 transmission connecting block 833 and the driven screw 834, and the No. 2 transmission connecting block 843 is movably connected to the No. 2 transmission screw 842.

[0030] Working principle: When using an endoscopic surgical positioning device, the endoscopic probe 7 is connected to the display panel 4 through the No. 1 connecting line 5 and the No. 1 connecting plug 51, and the point positioning device 8 is connected to the display panel 4 through the No. 2 connecting line 6 and the No. 2 connecting plug 61. The point positioning device 8 can be connected to a position above the bed or the ceiling of the hospital or other convenient positioning position through the connecting frame 81. After the connection and fixing work is completed, the operation can be performed. Before performing the operation, the doctor usually performs some imaging examinations, such as X-rays, CT scans, MRI, etc. to obtain imaging information of internal organs. Through these images, the doctor can determine the starting position of the endoscopic probe 7 as well as the expected path and target position, and mark fixed reference points on the patient's body surface.

[0031] According to the type of surgery, the endoscope probe 7 is inserted into the body along the wound or other body parts, and in urology surgery, it is inserted into the body through the urethra. After the endoscope probe 7 enters the body, the movement of the endoscope probe 7 is controlled by the control panel 21 on the connecting handle 2. The endoscope probe 7 can be turned through the optical hose 71 and the position where the endoscope probe 7 is inserted can be illuminated to facilitate observation of the surgical position. The camera probe 74 takes a picture of the endoscopic part and transmits it to the display panel 4. When the designated position is reached, the surgical part 73 performs the surgery, and the sensing element 75 transmits the magnetic field signal to be positioned at the point. The positioning tracking device 844 of the device 8 receives and controls the lateral moving device 83 and the longitudinal moving device 84 to move from a predetermined reference point according to the change of the transmitted magnetic field signal, and emits infrared light to indicate the position outside the body, so as to facilitate the external auxiliary surgery. When a wound is accidentally caused in the body during the operation, the operation can be performed externally according to the positioning point in time, and the wound position can be sutured. When performing lithotripsy, it is sometimes necessary to perform fixed-point lithotripsy on the stones in the body externally, and then clean the broken stones through the surgical piece 73 connected to the endoscopic probe 7.
