Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a gamma knife head support bracket. Background Technology

[0002] Gamma Knife, a stereotactic radiosurgery device, is widely used for the non-invasive treatment of intracranial tumors, vascular malformations, and functional diseases. Its core principle is to precisely destroy the lesion by focusing multiple beams of gamma rays onto the target site. Gamma Knife treatment is typically performed by two doctors working together. One doctor uses their hands as a support while the other assists in installing the head frame on the patient. This process is inconvenient and easily affected by external factors.

[0003] A bracket for assisting in the installation of a gamma knife head frame, with patent publication number CN215136099U, includes a frame for supporting the gamma knife head frame; two shoulder supports, respectively placed on the patient's shoulders, both connected to the frame, and each shoulder support is movable relative to the frame to adjust the position of the frame relative to the patient's head; in use, the shoulder supports are placed on the patient's shoulders, with the shoulders supporting the overall weight of the bracket and head frame. This technical solution has the following drawbacks: it relies on multi-component adjustment (slider, lead screw, universal joint, etc.), requiring simultaneous adjustment of height, level, and forward / backward position, making the operation cumbersome and inefficient in emergency medical scenarios; the shoulder support contact surface relies solely on a rigid, arc-shaped structure, lacking cushioning design, and prolonged pressure can easily lead to shoulder pain in the patient. Utility Model Content

[0014] The above-mentioned technical solution of this utility model has the following beneficial effects:

[0015] This utility model of a gamma knife head support adopts a pneumatic lifting column structure and its control module, which can precisely adjust the height on both sides, ensuring synchronous and accurate height adjustment on both sides and reducing the time-consuming process of traditional manual adjustment. The support also adopts precise control of the pitch angle. Through the shallow tooth meshing structure of the annular wheel and the rotating shaft, combined with the rotation angle scale, it can achieve ±30° pitch adjustment with a graduation accuracy of 1°, meeting the precise needs of complex treatment positions.

[0016] The shoulder support of this utility model gamma knife head frame uses a detachable sponge pad to increase patient comfort. At the same time, the appropriate thickness of sponge pad can be selected and glued according to the thickness of the patient's shoulder, making it more flexible to use. The sponge pad connected by Velcro can be replaced within 30 seconds, which meets the requirements of efficient turnover in the operating room.

[0017] This utility model bracket, by installing a level within the side groove of the support frame, can monitor and provide feedback on the frame's horizontal status in real time, ensuring the absolute horizontality of the Gamma Knife head frame and avoiding three-dimensional orientation deviations caused by tilting. The level is linked to the pneumatic lifting column, allowing doctors to quickly adjust the height difference between the two sides. Attached Figure Description

[0019] Figure 2 This is a schematic diagram of the pitch adjustment joint of this utility model. Detailed Implementation

[0020] The implementation of the gamma knife head holder of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 As shown, the present invention discloses a gamma cutter head holder support, including a support frame 1 for supporting the gamma cutter head holder, and clamping members 2 for supporting the gamma cutter head holder are respectively provided on both sides of the top of the support frame 1.

[0022] The supporting frame 1 is made of high-strength aluminum alloy and has an overall U-shaped structure with dimensions of 600mm × 400mm × 50mm (length × width × height). Pneumatic lifting columns 5 are connected to both sides of the bottom of the supporting frame 1. The bottom of the supporting frame 1 has threaded joints that are bolted to the flange 51 at the top of the pneumatic lifting column 5. Two arched shoulder supports 9 are connected to the bottom of the pneumatic lifting column 5 via pitch adjustment joints. A control module is connected to the pneumatic lifting column 5, which controls the synchronous lifting and locking of the pneumatic lifting column 5 via electrical signals. Removable sponge pads 10 are attached to the bottom of the arched shoulder supports 9 via Velcro. The pneumatic lifting column 5 can use a single-walled thin-film cylinder with a wall thickness of 2mm and a stroke of 150mm. A cable groove can be opened inside the outer shell of the pneumatic lifting column to embed the solenoid valve cable and sensor signal line. The air pump, solenoid valve, and guide sleeve are pre-assembled and integrated into the same device 55 and connected to the main body of the lifting column.

[0023] refer to Figure 1-2The pitch adjustment joint includes a circular wheel 70 connected to the pneumatic lifting column 5 on its side, a vertical rod 71 connected to the arched shoulder support 9, a circular base 77 located at the top of the vertical rod 71, and a rotating shaft 72 extending horizontally from the center of the circular base 77. The inner ring of the circular wheel 70 is provided with shallow teeth. The rotating shaft 72 passes through the circular wheel 70 and has a retaining edge 73 extending around its outer periphery. The surface of the rotating shaft 72 is provided with teeth that mesh with the shallow teeth of the circular wheel 70. The retaining edge is provided with a threaded hole (such as an M6 threaded hole), and a locking screw 74 is screwed into the threaded hole. When the locking screw 74 is tightened, it presses against the side wall of the circular wheel 70, which can ensure the stability of the circular wheel 70 when it is in the correct position.

[0024] The circular wheel 70 has a rotation angle scale on its surface, with a scale division of 1° and a range of ±30°; the rotating shaft 72 has marking lines on its surface, which are aligned with the scale to achieve angle reading. The outer edge of the circular wheel 70 is machined with a 1mm deep anti-slip texture for easy hand-held rotation.

[0025] The clamping component 2 is a C-shaped transparent clamping block, which can be made of polycarbonate material with a thickness of 5mm; it is fixed from the outer end of the side frame of the gamma knife head holder. The C-shaped transparent clamping block includes a straight top edge 201 and an L-shaped bottom edge 202, which ensures stable support and easy removal; the folded edge of the L-shaped bottom plate 202 extends upward and has a height of 3-8mm. The inner wall surfaces of both the straight top edge 201 and the L-shaped bottom edge 202 are provided with anti-slip textures, which are diamond-shaped anti-slip textures with a depth of 0.5mm.

[0026] The sponge pad 10 is made of medical-grade polyurethane foam, and its thickness is set according to actual conditions, specifically 8-15mm. The sponge pad 10 has multiple openings 100, with a hole diameter of 3mm and a hole spacing of 5mm. The surface of the sponge pad 10 is decorated with silicone dot matrix embossing 101, with a raised height of 0.5mm and a diameter of 1.5mm. It is connected to the shoulder support 9 via Velcro, and can be replaced within 30 seconds.

[0027] The supporting frame 1 has side grooves 12 on both sides, and a level 13 is installed in the side grooves 12. The level 13 is a biaxial bubble level with a sensitivity of ±0.5°.

[0028] Before use, calibrate and operate the control module (touchscreen or button) to simultaneously activate the pneumatic lifting columns on both sides, raising the support frame to the estimated height of the patient's head (approximately level with the upper edge of the ear). Loosen the locking screws of the pitch adjustment joints, hold the anti-slip texture of the outer edge of the ring wheel, and rotate the vertical rod to make the shoulder rest conform to the curve of the patient's shoulder. Align the markings on the rotating shaft scale with the angle scale to precisely adjust the pitch angle. After completion, tighten the locking screws to secure the ring wheel.

[0029] Select a sponge pad with a thickness of 8-15mm based on the patient's shoulder width and attach it to the bottom of the arched shoulder support using Velcro. Gently place the two arched shoulder supports on the patient's shoulders and observe the position of the bubble on the level indicator. If there is any tilt, fine-tune the height of the pneumatic lifting column using the control module until the dual-axis level indicator shows a completely horizontal position. Insert the Gamma Knife head frame side bracket into the C-shaped transparent retaining blocks on both sides of the support frame, using the anti-slip texture on the inner wall to ensure no slippage. After use, remove the head frame, press the lowering button of the pneumatic lifting column to reset the bracket, and remove the sponge pad for disinfection or replacement.
