[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of a head protection frame for interventional surgery, including a mounting plate 1, a connecting plate 2 at the top of the mounting plate 1, the mounting plate 1 being bolted to the surgical area, a support column 3 fixedly connected to the top of the connecting plate 2, the support column 3 primarily supporting and connecting the head seat 12, a circular sleeve 4 slidably connected to the outer wall of the support column 3, a limit mechanism being provided on the inner wall of the circular sleeve 4, and an electric telescopic rod 8 hinged to the outer wall of the circular sleeve 4 via a hinge rod 7, the electric telescopic rod 8 being raised and lowered electrically, and vertically moving along with the fixing block 9, threaded rod 10 and contact plate 11 via the electric telescopic rod 8, which can meet different needs. The fixed height of the patient's head is achieved by fixing a fixed block 9 at the movable end of the electric telescopic rod 8. A threaded rod 10 is threaded through the inner wall of the fixed block 9 and threaded to it. The inner wall of the fixed block 9 and the threaded rod 10 have corresponding textures, which allows the threaded rod 10 to move laterally with the contact plate 11. The left end of the threaded rod 10 is rotatably connected to the contact plate 11, which can contact and fix the patient's head, ensuring that the patient's head will not move during the operation. A head seat 12 is fixedly connected to the top of the support column 3, allowing the patient's head to be placed on the head seat 12 for positioning, which facilitates subsequent fixation of the patient's head. A rotating component is provided on the inner wall of the connecting plate 2.

[0033] The limiting mechanism includes a wedge 6, which is slidably connected to the inner wall of the sleeve 4. The wedge 6 is inclined, and when the inclined surface is squeezed, it will move laterally along the inner wall of the sleeve 4. The inner side wall of the wedge 6 is elastically connected to the sleeve 4 through a return spring 5.

[0034] Reference Figures 4-5 The rotating assembly includes a movable column 14, which is fixedly connected to the inner wall of the connecting plate 2. A circular tube 13 is rotatably connected to the inner wall of the connecting plate 2. When the connecting plate 2 rotates, it rotates in a ring around the circular tube 13 to ensure a certain degree of angle change between the patient's head and neck. A retaining plate 16 is elastically connected to the inner wall of the left end of the movable column 14 via a positioning spring 15. The inner wall of the left end of the movable column 14 is fixedly connected to one end of the positioning spring 15. When the retaining plate 16 moves to the left, it compresses the positioning spring 15. During reset, the spring force of the positioning spring 15 is used to reset the position. The other end of the positioning spring 15 is connected to the retaining plate 16. The left end is fixedly connected, and the card plate 16 is slidably connected to the inner wall of the moving column 14. The moving column 14 has a slot corresponding to the card plate 16, which allows the card plate 16 to slide along the slot of the moving column 14. The card plate 16 is inserted into the inner wall of the mounting plate 1. The mounting plate 1 has a slot with the same movement trajectory as the card plate 16, which allows the card plate 16 to be inserted into the slot of the mounting plate 1 to limit the position of the entire connecting plate 2. The round tube 13 is fixedly connected to the top of the mounting plate 1. The moving column 14 is slidably connected to the inner wall of the mounting plate 1. The mounting plate 1 has an opening corresponding to the moving column 14, which allows the moving column 14 to slide left and right along the opening.

[0035] Reference Figures 1-3 The outer wall of the circular sleeve 4 is hinged to one end of the hinge rod 7. The length of the hinge rod 7 is fixed. When the circular sleeve 4 moves downward with one end of the hinge rod 7, it will cause the other end of the hinge rod 7 and the electric telescopic rod 8 to move closer together. Conversely, when the circular sleeve 4 moves upward with one end of the hinge rod 7, it will cause the other end of the hinge rod 7 and the electric telescopic rod 8 to separate. The other end of the hinge rod 7 is hinged to the bottom end of the electric telescopic rod 8. The electric telescopic rod 8 passes through and slides on the inner wall of the head base 12. Openings are made on both sides of the head base 12. The slot allows the electric telescopic rod 8 to move laterally along its inner wall. The inner side wall of the wedge 6 is fixedly connected to one end of the return spring 5. When the wedge 6 moves outward, it will stretch the return spring 5. When resetting, the elastic force of the return spring 5 will carry the wedge 6 to reset. The other end of the return spring 5 is fixedly connected to the outer wall of the circular sleeve 4. The wedge 6 is inserted into the outer wall of the support column 3. The support column 3 has a slot corresponding to the wedge 6, which can satisfy the one-way limit of the circular sleeve 4 by the wedge 6 and its insertion.

[0036] Working principle: First, to adapt to different patients' head fixation needs, simply place the patient's head on the headrest 12. Then, the electric telescopic rod 8 is electrically activated to control the height of the fixing block 9, the threaded rod 10, and the contact plate 11, so that the contact plate 11 can reach the contact height of the patient's head. Then, the circular sleeve 4 moves downward, causing the hinge rod 7 to bring the entire electric telescopic rod 8 closer together. As the circular sleeve 4 moves, the groove on the outer wall of the support column 3 presses against the inclined surface of the wedge block 6, causing the wedge block 6 to move outward and stretch the return spring 5, separating the wedge block 6 from the groove on the outer wall of the support column 3. When the wedge block 6 and the next groove on the outer wall of the support column 3 coincide, the reverse elastic force of the return spring 5 is used to reset the wedge block 6, allowing the wedge block 6 to engage with the groove on the outer wall of the support column 3 and unidirectionally limit the circular sleeve 4. When the contact plate 11 is about to contact the patient's head, simply rotate the threaded rod 10 manually to move the threaded rod 10 and the contact plate 11 toward the patient's head for fine adjustment, ensuring the comfort of the patient's head in contact with the contact plate 11.

[0037] If it is necessary to change the angle of the patient's head, simply move the clamping plate 16 to the left and compress the positioning spring 15 to separate the clamping plate 16 from the inner wall groove of the mounting plate 1. Then, adjust left and right according to the actual needs, keeping the patient's cervical spine still while the patient's head changes from left to right. When it is necessary to limit the position, simply release the clamping plate 16 and use the reverse elastic force of the positioning spring 15 to reset the clamping plate 16, allowing the clamping plate 16 to engage with the inner wall groove of the mounting plate 1, thus completing the change of the angle of the patient's head.

[0038] When it is necessary to release the fixation on the patient's head, simply pull the wedge 6 outward and stretch the return spring 5. Manually move the wedge 6 upward with the sleeve 4, and the hinge rod 7 will separate from the entire electric telescopic rod 8, so that the contact plate 11 is no longer in contact with the patient's head. Finally, release the wedge 6 and use the elastic force of the return spring 5 to reset the wedge 6.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
