The device allows doctors to adjust the angle of the glasses according to surgical needs through the design of adjustment structure, rotation structure and distance adjustment structure to ensure the best field of view. This helps doctors observe the details of the affected area more clearly and improve the accuracy of the surgery. The device can also adapt to the pupil distance of different doctors to ensure that the images seen by both eyes through the glasses are clear and overlapping, reducing visual fatigue and errors.
[0036] The use process of a gynecological clinical head-mounted surgical auxiliary device provided by the present invention is as follows: the user wears the device on the head and rotates the handle 3 according to the doctor's head size. The rotation of the handle 3 drives the first screw 2 to rotate. Since the outer side of the first screw 2 is threadedly connected to the head cover 1, the rotation of the first screw 2 can push the push clamp 4 to move back and forth, thereby being able to adapt to the patient's head size and ensure the stability of wearing. The user pulls the buckle 36, thereby stretching the spring 38 and causing the insertion rod 37 to slide on the inner side of the limit plate 35 and disengage from the plug-in connection with the concave block 6. The user rotates the knob 34, thereby rotating the second rotating column 33 and the sliding rod 7, thereby adjusting the angle of the sliding rod 7. After the adjustment is completed, the user releases the buckle 36 and releases the spring. Under the elastic force of the spring 38, the insertion rod 37 slides on the inner side of the limit plate 35, and the insertion rod 37 is restored to the plug-in connection with the recessed block 6. The user energizes the small motor 14 to rotate, and the output end of the small motor 14 drives the second screw 15 to rotate. Since the outer side of the second screw 15 is threadedly connected to the first slider 13, the rotation of the second screw 15 drives the first slider 13 to rise, and the rising of the first slider 13 drives the connecting block 12 and the motor 16 to rise. The user energizes the motor 16 to rotate, and the output end of the motor 16 drives the second gear 17 to rotate. Since the second gear 17 is raised and meshed with the third gear 18, the rotation of the second gear 17 drives the third gear 18 to rotate, and the rotation of the third gear 18 drives the first rotating column 19 to rotate, and the first rotating column The rotation of 19 drives the stud 20 to rotate. Since the outer side of the stud 20 is threadedly connected with a slide plate 21, the rotation of the stud 20 drives the slide plate 21 to move, thereby causing the slide bar 7 to move on one side of the slide sleeve 8, and adjusting the relative distance between the slide bar 7 and the slide sleeve 8. When it is necessary to adjust the angle of the concave plate 24, the user rotates the small motor 14 in the opposite direction, thereby lowering the motor 16, so that the second gear 17 is disengaged from the meshing connection with the third gear 18, and at the same time restores the meshing connection with the first gear 11. The rotation of the second gear 17 drives the first gear 11 to rotate, thereby driving the rotating rod 10 to rotate. The rotation of the rotating rod 10 drives the first bevel gear 22 to rotate. Since one side of the first bevel gear 22 is meshedly connected with the second bevel gear 23, the rotation of the first bevel gear 22 drives The second bevel gear 23 rotates, thereby driving the concave plate 24 to rotate, thereby adjusting the angle of the concave plate 24. The rotation of the concave plate 24 drives the first connecting plate 25 to rotate. The user rotates the handle 29, and the rotation of the handle 29 drives the bidirectional screw 28 to rotate. Since both ends of the outer side of the bidirectional screw 28 are threadedly connected to the second connecting plate 30, and since both ends of the outer side of the bidirectional screw 28 are provided with threads with opposite thread rotation directions, the rotation of the bidirectional screw 28 drives the two second connecting plates 30 to move closer to or away from each other, thereby adjusting the distance between the two observation mirrors 32, so that the device can meet the doctor's usage requirements. In summary, the present invention will significantly improve the quality of surgical field of view, wearing comfort, surgical efficiency, and promote technological innovation and industry development.
