Technical Field

[0001] This utility model relates to the field of medical devices, and more specifically, to an auxiliary fixation device for the head of an operating table. Background Technology

[0002] During surgery, stable fixation of the patient's head is one of the key factors for surgical success. Traditional operating table head fixation devices mostly use rigid clamping structures (such as metal buckles or straps). Although they can provide basic fixation, the rigid materials are in direct contact with the head and neck, which can easily cause local pressure. Prolonged surgery may lead to pressure sores or nerve damage. Moreover, the fixation structure is singular and cannot adapt to the different head circumference, neck curvature, and surgical positioning requirements of different patients, which can easily lead to loosening of the fixation or excessive pressure. Utility Model Content

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] like Figure 1-4 The operating table head-supporting device shown includes a neck support 1 and a head-fixing component 2 located on one side of a rubber support 9. A device slide plate 3 for fixing the neck support 1 is provided at the bottom of the neck support 1. A base 4 installed on the operating table is provided below the device slide plate 3. A movable adjusting component 5 is provided between the base 4 and the device slide plate 3. The adjusting component 5 controls the neck support 1 and the device slide plate 3 to move back and forth on the base 4. The head-fixing component 2 includes at least two sets of symmetrically arranged clamping components 6. A rubber buffer pad 7 is provided at the bottom of the two sets of clamping components 6.

[0021] Based on the above, the base 4 in the device is installed and fixed on the operating table by bolts or other means. The neck support 1 supports the patient's neck, and the neck support 1 and the device slide plate 3 can move back and forth on the base 4. The neck support 1 can be finely adjusted according to the length of the patient's neck. The patient's head is located between the two sets of clamps 6, with the bottom of the head attached to the rubber buffer pad 7. The sides are fixed and limited by the clamps 6, thus completing the auxiliary fixation of the head.

[0022] The neck support includes a base plate 8 that fits against the surface of the equipment slide plate 3 and a rubber support 9 mounted on the base plate 8. The surface of the rubber support 9 is provided with a recessed support groove 10. The surfaces of the rubber support 9 on both sides of the support groove 10 are inclined arcs, and the side closer to the head fixing member 2 is raised upwards. The support groove 10 adopts a biomimetic arc design.

[0023] At least two first spiral tubes 11 are embedded at the bottom of the rubber support 9, and a first bolt 12 is inserted through the base plate 8 into the first spiral tube 11. The bottom end of the first bolt 12 is flush with the bottom of the base plate 8.

[0024] Based on the above, the concave design of the support groove 10 matches the curvature of the cervical spine, and the arc-shaped bulges on both sides provide lateral support to prevent lateral displacement of the neck. The base plate 8 is fixed to the rubber support seat 9 by the first bolt 12, so as to realize the quick installation or removal of the rubber support seat 9, which is convenient for cleaning or replacement. The bottom end of the first bolt 12 is flush with the base plate 8 to avoid the protrusion interfering with the sliding of the equipment slide plate 3 and causing scratches to the patient's head.

[0025] The base 4 has a recessed slot 13 at its bottom. The adjusting member 5 is located inside the slot 13. A sliding groove 14 that penetrates the base 4 is provided at the top of the slot 13. The adjusting member 5 includes a sliding plate 15 inserted into the sliding groove 14 and a screw 16 located inside the slot 13. A second spiral tube 17 that moves back and forth is sleeved on the outside of the screw 16. The bottom end of the sliding plate 15 is fixedly connected to the second spiral tube 17 and the top end is fixedly connected to the base plate 8. The front end of the screw 16 is flush with the outer wall of the base 4. A bearing 18 is sleeved on the rear end of the screw 16 and the bearing 18 is fixed on the inner wall of the rear side of the slot 13.

[0026] Based on the above, when the screw 16 is rotated, the second screw tube 17 moves along the axial direction of the screw 16, causing the slide plate 15 to slide in the slide groove 14, thereby driving the equipment slide plate 3 and the neck support seat 1 to move back and forth. The bearing 18 supports the rear end of the screw 16, eliminating axial movement during rotation and ensuring a smooth adjustment process without deviation.

[0027] The base 4 extends below the head fixing member 2, and the surface of the base 4 located below the head fixing member 2 is recessed downwards, with the rubber buffer pad 7 located in the recess of the base 4.

[0028] Based on the above, the recessed area of ​​the base 4 accommodates the rubber cushioning pad 7. After the patient's neck is supported, the head is placed on the rubber cushioning pad 7. The cushioning pad absorbs pressure through elastic deformation and evenly transmits the pressure to the base 4, improving the user experience.

[0029] The clamping member 6 includes a vertical plate 19 fixed at the edge of the surface of the base 4. The vertical plates 19 in the two sets of clamping members 6 are symmetrically arranged on both sides of the rubber buffer pad 7. Several third spiral tubes 20 are installed on the outer side wall of the vertical plate 19. An adjusting screw 21 that penetrates the vertical plate 19 is inserted into the third spiral tube 20. A fourth spiral tube 22 is sleeved at the end of the adjusting screw 21 located on the inner side of the vertical plate 19. A rubber ball 23 is fixed at the end of the fourth spiral tube 22.

[0030] Based on the above, each clamping component 6 is provided with multiple third solenoids 20. By rotating the adjusting screw 21, the fourth solenoid 22 and the rubber ball 23 are pushed closer to the head to achieve multi-angle clamping. The soft material of the rubber ball 23 reduces the hard pressure on the head, and at the same time, the clamping force is evenly distributed through multi-point synchronous adjustment.

[0031] Furthermore, by combining the dual elastic structure of the rubber ball 23 and the cushioning pad, "rigid fixation and flexible contact" are achieved, improving patient comfort.

[0032] Based on the above, this utility model can apply local pressure to different contours of the head through the multi-point adjustment mechanism of the clamping component 6, avoiding a single point of force. The rubber ball 23 and the buffer pad form a "soft contact-hard support" combination, which ensures the fixation strength and avoids the risk of pressure sores.

[0033] By deeply integrating the precision of mechanical transmission and the adaptability of elastic materials, the problems of rough adjustment and poor comfort of traditional head fixation devices have been solved.

[0034] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
