[0043] The three-dimensional free hovering control mechanism 3 includes a support frame 31, a lateral movement component 32 for controlling the lateral horizontal movement of the laparoscopic instrument 2, a vertical movement component 33 for controlling the vertical horizontal movement of the laparoscopic instrument 2, a lateral horizontal control component, a vertical horizontal control component, and a movable component 36 for driving the rotation of the laparoscopic instrument 2. The support frame 31 is connected to the rotation angle control component 53; the lateral movement component 32 is installed on the support frame 31; the vertical movement component 33 is installed on the lateral movement component 32;

[0044] The lateral horizontal control component and the vertical horizontal control component have the same structure and function. The lateral horizontal control component is installed on the lateral movement component 32, and the vertical horizontal control component is installed on the vertical movement component 33;

[0046] A synchronous traction mechanism 4 for traction on the patient's abdomen is further installed at the lower end of the support frame 31;

[0047] The synchronous traction mechanism 4 includes a clamping component 41 for clamping the patient's abdomen and a driving component 42 for controlling the movement of the clamping component 41;

[0048] The clamping component 41 is installed at the lower end of the support frame 31, and the driving component 42 is installed on the clamping component 41;

[0049] In the present invention, medical staff adjust the rotation angle of the support frame 31 through the rotation angle control component 53 according to the abdominal bulge condition of the patient and the position of the organ to be treated by the patient. The orientation of the support frame 31 is made to correspond to the position of the organ to be treated by the patient. Subsequently, the height control component 51 drives the moving support plate 52 to move downward until the clamping component 41 moves to the patient's abdominal position. Then, the driving component 42 operates to drive the clamping component 41 to work, fixing the patient's abdomen.

At this time, the patient's abdomen will be tractioned and stretched, providing sufficient space for subsequent laparoscopic surgery; the height control component 51 and the rotation angle control component 53 can accurately control the spatial position of the clamping component 41, enabling the clamping component 41 to exert a traction effect on the abdomens of patients with different body types, improving the practicality of the device;

[0050] After the patient's abdomen is tractioned and stretched by the clamping component 41, medical staff can perform trocar puncture operations on the patient's abdomen; subsequently, the laparoscopic instrument 2 is inserted downward from the middle of the airbag tube 35 until the laparoscopic instrument 2 extends into the patient's abdominal cavity through the trocar.

At this time, the lateral movement component 32 drives the vertical movement component 33 and the airbag tube 35 to perform lateral horizontal movement, causing the laparoscopic instrument 2 to swing left and right along with the movable component 36; after the adjustment is completed, the lateral horizontal control component continues to maintain the movement restriction on the lateral movement component 32. At this time, the rotation angle of the laparoscopic instrument 2 will be fixed; similarly, the movement restriction on the vertical movement component 33 can be released through the vertical horizontal control component. At this time, the vertical movement component 33 drives the airbag tube 35 to perform vertical horizontal movement, causing the laparoscopic instrument 2 to swing back and forth along with the movable component 36; through the cooperation of the lateral movement component 32, the vertical movement component 33 and the movable component 36, the rotation angle of the laparoscopic instrument 2 can be accurately controlled, and through the lateral horizontal control component and the vertical horizontal control component, the rotation angle of the laparoscopic instrument 2 is maintained, reducing the extra workload that requires medical staff to manually fix the laparoscopic instrument 2 for a long time and reducing the probability of the change of the viewing angle caused by the movement of the laparoscopic instrument 2.

[0054] Both the lateral horizontal control assembly and the vertical horizontal control assembly are composed of a sliding rod 343, a return spring 344, a pull plate 345 and a locking plate 346. Yielding grooves 341 are provided on the front side of the first moving plate 322 and the left side of the second moving plate 332. Chute grooves 342 are symmetrically provided on the left and right sides in front of the upper end of the first moving plate 322 and on the front and rear sides on the left of the upper end of the second moving plate 332.

[0057] In the present invention, when it is necessary to control the left - right swing of the laparoscopic instrument 2, the pull plate 345 on the first moving plate 322 is pulled upward. The pull plate 345 drives the sliding rod 343 and the locking plate 346 to move upward along the chute 342. During the movement, the return spring 344 will be pulled upward. At this time, the lower end of the locking plate 346 leaves the first guide rod 321 on the front side. Subsequently, the first moving plate 322 can be driven to move left and right. At this time, the air - bag tube 35 moves left and right together with the first moving plate 322. The air - bag tube 35 drives the upper end of the laparoscopic instrument 2 to move left and right. At this time, the rotating frame 362 will drive the middle part of the laparoscopic instrument 2 to swing left and right around the hinge point between the rotating frame 362 and the support bait plate 361 until the viewing angle of the laparoscopic instrument 2 rotates to the set position. Then, the pull plate 345 is released, and the return spring 344 restores to drive the pull plate 345 to reset. At this time, the locking plate 346 fits with the upper end of the first guide rod 321 on the front side, preventing the first moving plate 322 from moving and also fixing the tilt angle of the laparoscopic instrument 2.
