[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0030] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0031] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0032] like Figure 1 and Figure 10 As shown, the present invention provides a bracket for assisting the installation of a gamma knife head frame, which provides assistance for the installation of the gamma knife head frame for patients undergoing gamma knife surgery on the head. The bracket includes:

[0033] The frame 1P is used to support the gamma knife head frame 29. Specifically, a head frame support platform 8 is installed on the frame 1P to support the gamma knife head frame 29. The head frame support platform 8 is distributed on both sides of the U-shaped frame and can be in seamless contact with the gamma knife head frame.

[0034] The shoulder supports 2P on both sides are respectively placed on the shoulders of the patient. Both shoulder supports 2P on both sides are connected to the frame. Each shoulder support 2P and the frame 1P can move relative to each other to adjust the position of the frame 1P relative to the patient's head.

[0035] The device further comprises a waist support 3P, which is connected to the frame 1P via a deformable connector 21 . The waist support 3P can be detachably fixed to the patient's waist.

[0036] The above embodiment provides a bracket for correctly, accurately, conveniently and efficiently installing a gamma knife head frame for patients who need gamma knife surgery on their heads, reducing the impact of human factors other than the patient on the installation accuracy of the gamma knife head frame. During actual use, the shoulder supports 2P on both sides are placed on the patient's shoulders respectively, and the shoulders support the overall mass of the bracket and the gamma knife head frame 29; the waist support 3P is tied to the patient's waist with a belt, and the frame is kept in a balanced state through the deformable connecting member 21.

[0037] The main further explanation is that, Figure 6 As shown, the deformable connector 21 can be a deformable pipe or a deformable rod, or other deformable rod-shaped object, taking into account flexibility and support rigidity. The deformable connector 21 can specifically be a metal hardened hose, which can change shape under the action of external force. On the one hand, it can be flexibly used by patients with different body shapes, and on the other hand, it makes the overall folding and storage of the bracket more convenient. In order to further ensure its use effect, the metal hardened hose can be a gooseneck metal tube, which can be bent in any direction to adjust its direction after being subjected to force. The deformable pipe is connected to the lumbar support 3P at one end through a universal joint 22. The universal joint 22 is installed on the universal joint mounting slot 6.

[0038] In the entire structure, the weight of the head frame and the frame is supported by the shoulder supports on both sides, and the frame base is balanced by the waist support and the metal hardened hose, so that the frame base is always in a stable state during use.

[0039] Both ends of the metal hardened hose are installed through universal joints, and the connection between the metal hardened hose and the universal joint is screwed in. It can be replaced with metal hardened hoses of different lengths at any time as needed to meet the usage requirements of patients of different heights.

[0040] In one embodiment, the frame base 1 is also provided with a fastening slot 4 on the side to accommodate the movement of the gamma knife head frame. The fastening slot on the frame allows the head frame to move within a 45mm range in the front-to-back direction, accommodating the needs of people of different body shapes. The frame base has a planar size of 253mm x 226mm. The length between the two centers of the fastening slot 4 is 45mm, and the slot width is 12mm.

[0041] Among them, such as Figure 6 As shown, the lumbar support 3P includes a support base 19 with a belt hole 20 for passing a waist belt through it. The support base 19 also features a sloped surface 24, to which the metal hardened hose is secured via a universal joint 22. The belt hole 20 is a 5mm x 45mm rectangular hole, essentially accommodating the width, thickness, and curvature of a waist belt. A universal joint mounting hole is provided on the support base 19, allowing for smooth insertion of the universal joint. The support base 19 is a 150mm x 30mm x 15mm rectangular parallelepiped, allowing a 150mm contact surface to rest against the patient's waist during use, overcoming the problem of conventional 50mm x 30mm x 15mm waist supports flipping up and down along the waist belt.

[0042] In one embodiment, Figure 7 and Figure 8 、 Figure 10 As shown, the shoulder support 2P is movably connected to the frame 1P via a slider 10. The frame 1P includes a frame base 1. The frame base 1 is mounted near the back and side of the patient's head, respectively, with at least one headgear fixing rear clamp 27 and at least one headgear fixing side clamp 28. The frame base 1 is also provided with a slideway 2 along its length for the slider to move. The slider 10 is also provided with a 45° dovetail 12.

[0043] The sliders 10 are connected to the slideways on the left and right sides of the frame base 1, relying on the slideways to support the entire mass of the frame and headstock. The sliders 10 are locked and fixed by tightening the threads and pressing against the bottom of the frame base 1.

[0044] By adjusting the curvature of the metal hardened hose, the spacing between the frame base 1 and the lumbar support base 19 is changed so that the frame base 1 remains horizontal. In order to simply and conveniently verify whether it is horizontal, a universal level bubble 25 is installed on the frame base. Specifically, a universal level bubble embedding hole 5 is provided on the frame base to embed and install the universal level bubble 25. If the universal level bubble 25 is in a fixed position in the middle of the front-to-back (longitudinal) direction, it indicates that it is horizontal. The curvature of the metal hardened hose can be adjusted so that the level bubble in the front-to-back direction (longitudinal) is in the center position. By adjusting the screws on the two shoulder supports 2P, the distance between the frame and the patient's left shoulder or right shoulder is changed so that the level bubble of the frame is centered in the left-right (transverse) direction.

[0045] The frame is provided with a limit column 7 to prevent the slider from falling off. When the slider 10 moves to a preset position, a locking bolt 13 is used to lock it.

[0046] In one embodiment, Figure 5As shown, the shoulder support includes a shoulder support base 14, one end of which is connected to the frame 1P, and the other end is provided with a shoulder contact surface 18 that fits closely with various types of shoulders. The shoulder contact surface 18 adopts an arc with a radius of 90mm, which can basically meet the needs of most patients.

[0047] According to a preferred embodiment of the present invention, the shoulder support is connected to the frame 1P via a liftable structure 4P. The height of the frame 1P can be adjusted as needed to accommodate patients of different heights and neck lengths. The shoulder support base 14 is connected to the liftable structure 4P via a universal foot cup 15.

[0048] Specifically, such as Figure 7 As shown, the lifting structure 4P includes an extension nut 11 provided on the frame base 1, and a screw rod 17 with one end screwed into the extension nut, and the other end of the screw rod 17 not screwed into the extension nut is connected to the shoulder 2P.

[0049] The universal foot cup 15 selected in the design has two functions. First, when the screw rod 17 is vertically downward, the angle can be adjusted by relying on the universal foot cup 15 so that the shoulder support can fit closely with various types of human shoulders. Second, because the universal foot cup 15 and the screw rod 17 are connected by a spherical surface, the screw rod 17 can rotate clockwise or counterclockwise and be combined with the extended nut 11. By increasing or decreasing the threaded part in the extended nut 11, the length of the screw rod between the slider and the shoulder support is adjusted, thereby changing the distance between the frame base 1 and the shoulder support 2P to meet the patient's usage requirements.

[0050] According to a preferred embodiment of the present invention, the shoulder support is movably connected to the frame 1P via a slider, and a limiting column 7 is provided on the frame 1P to prevent the slider from falling off, thereby preventing the slider 10 from falling off from the rear end when the frame 1P is not locked during installation, thereby reducing the psychological burden of guarding against the slider 10 falling off.

[0051] According to a preferred embodiment of the present invention, the distance between the shoulder support and the frame is adjustable, specifically the distance between the slider 10 and the shoulder support 2P is adjustable, and the two are connected by a screw rod, and an adjustment hand handle 16 is provided on the screw rod. The distance between the slider 10 and the shoulder support 2P is adjusted by adjusting the hand handle 16 to adapt to different patients.

[0052] According to a preferred embodiment of the present invention, the liftable structure includes an extension nut 11 provided on the frame 1P, and a screw rod with one end screwed into the extension nut 11, and the other end of the screw rod not screwed into the extension nut is connected to the shoulder 2P.

[0053] According to a preferred embodiment of the present invention, the frame is provided with a scale along the direction of movement of the shoulder support. In actual operation, a ruler 3 is installed on the frame 1P to facilitate fast and accurate locking of the two independent sliders at the same position of the scale of the frame base 1.

[0054] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
