[0026] like Figures 1 to 6 As shown, the spatial suspension support auxiliary device of the endoscope camera head of the present embodiment comprises a base 1, a first balance arm 2, a second balance arm 3, a third balance arm 4 and a lens holder 9. The first balance arm 2, the second balance arm 3 and the third balance arm 4 are connected in sequence, the base 1 is connected to the lower end of the first balance arm 2, the lens holder 9 is connected to the end of the third balance arm 4, the base 1 is used to be fixedly connected to the side of the operating table, and the position of the lens holder 9 can be adjusted by adjusting the posture of the first balance arm 2, the second balance arm 3 and the third balance arm 4.

[0027] The sides of common operating beds are currently provided with slide rails, and the base 1 includes a slide groove 101 for cooperating with the slide rail, a clamping plate 102 is provided in the slide groove 101, and a through screw hole is provided on one side wall of the slide groove 101, and a fastening screw 103 is provided on the screw hole, one end of the fastening screw 103 extends into the slide groove 101 and is rotatably connected with the clamping plate 102, the fastening screw 103 rotates and moves back and forth, thereby driving the clamping plate 102 to move back and forth, and the guide rail located in the slide groove 101 can be clamped between the clamping plate 102 and the front side wall of the slide groove 101, thereby fixing the base 1 to the side of the operating bed.

[0028] In this embodiment, the first balance arm 2 is rotatably connected to the upper end of the base 1 around its axis; the second balance arm 3 is hinged to the upper end of the first balance arm 2; one end of the third balance arm 4 is hinged to the other end of the second balance arm 3; and the lens holder 9 is disposed at the other end of the third balance arm 4. In order to better swing and adjust the position of the lens holder 9, the hinge axis of the first balance arm 2 and the second balance arm 3 is perpendicular to the hinge axis of the second balance arm 3 and the third balance arm 4.

[0029] Specifically, a balancing mechanism 8 is arranged inside the first balancing arm 2 and the second balancing arm 3, and the balancing mechanism 8 includes a joint body A801, a joint body B804, a first rotating member 807, a second rotating member 808 and an elastic component 809. The joint body A801 ​​is provided with parallel rotating shafts A802 and B803, and the joint body B804 is provided with parallel rotating shafts C805 and D806. Both ends of the first rotating member 807 are respectively connected to the rotating shaft A802 and the rotating shaft C805, and both ends of the second rotating member 808 are respectively connected to the rotating shaft B803 and the rotating shaft D806. One end of the elastic component 809 is hinged to the first rotating member 807, and the other end of the elastic component 809 is hinged to the rotating shaft B803. Among them, the distance between the rotating shaft A802 and the rotating shaft B803 is equal to the distance between the rotating shaft C805 and the rotating shaft D806, the lengths of the first rotating member 807 and the second rotating member 808 are equal, so that a parallelogram structure is formed between them, the elastic component 809 can be an elastic component such as a spring, and the second balancing arm 3 can be connected to the rotating shaft D806 of the balancing mechanism 8 in the first balancing arm 2. After the second balancing arm 3 is rotated, a certain traction force is generated on it to maintain balance. Only when the applied force is greater than a certain value can it be rotated, so that the endoscopic camera 12 can be suspended and stopped at a certain position in the space to free the doctor's hand for other operations.

[0030] In order to facilitate the operation of the buttons on the handle of the endoscopic camera 12, the lens holder 9 includes an inner cavity for inserting the endoscopic camera 12, and a side hole 903 that penetrates the inner cavity is provided on the side of the lens holder 9 to expose the buttons of the endoscopic camera 12.

[0031] In addition, a storage tube 5 for storing the lens holder 9 is provided at the end of the third balance arm 4, and a retractable slide rod 10 is provided in the storage tube 5. For example, a sliding hole penetrating to the storage tube 5 is provided in the third balance arm 4, and the slide rod 10 can slidably cooperate with the sliding hole and has a certain resistance, and can be extended out of the storage tube 5. The lens holder 9 is connected to the slide rod 10. Specifically, a connecting plate 11 is hinged at the end of the slide rod 10, and the hinge shaft has a certain resistance. Sufficient force is applied to rotate the connecting plate 11. The lens holder 9 is connected to the connecting plate 11. By rotating the connecting plate 11, the direction of the lens holder 9 can be rotated and adjusted.

[0032] The lens holder 9 is detachably connected to the connecting plate 11. For example, a screw hole is provided at the end of the connecting plate 11, and a screw rod is provided on the back of the lens holder 9. The lens holder 9 can be fixed to the connecting plate 11 through the cooperation of the screw rod and the screw hole. When not in use, the lens holder 9 can be disassembled and stored in the storage tube 5 to keep the lens holder 9 clean. In order to prevent the lens holder 9 from being deformed by external force, the lens holder 9 can be sleeved on the outside of the slide rod 10. The slide rod 10 is the same size as the inner cavity of the lens holder 9. Therefore, when the lens holder 9 is stored, the slide rod 10 fills the inner cavity of the lens holder 9, which is conducive to preventing it from being deformed by external force. At the same time, the internal space of the storage tube 5 can be better utilized, and the structure occupies less space.

[0033] In this embodiment, the lens holder 9 includes a front half seat 902 and a rear half seat 901. One side of the front half seat 902 and the rear half seat 901 is connected by a hinge, and the other side of the front half seat 902 and the rear half seat 901 is connected by a buckle 904, which makes it easier to insert the endoscopic camera 12 into the lens holder 9.

[0034] The end of the storage tube 5 is provided with a dustproof cover 7 to keep the inside of the storage tube 5 clean, thereby keeping the lens holder 9 clean. In order to facilitate the adjustment, a handle 6 for operating the movement is provided on the outer wall of the storage tube 5.

[0035] During use, the base 1 can be first fixed on the side slide rail of the operating table, the slide bar 10 can be slid out from the storage tube 5, the lens holder 9 can be removed from the slide bar 10, connected to the connecting plate 11, the front half seat 902 of the lens holder 9 can be rotated to open, the endoscopic camera 12 can be placed in the rear half seat 901, and then the front half seat 902 can be closed to expose the button part of the endoscopic camera 12 from the side hole 903 for operation and control. Finally, the postures of the first balance arm 2, the second balance arm 3, and the third balance arm 4 can be adjusted to change the position and angle of the endoscopic camera 12 to obtain a better surgical field. The endoscopic camera 12 does not need to be held during the operation, which is more convenient for surgical operation.

[0036] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.
