DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] Embodiment 1, as Figure 1-2 As shown, a head angiography fixator for cerebrovascular surgery includes two handles 1, the lower ends of the two handles 1 are fixedly connected to a fixing group 2, a control panel 3 is provided on the upper left part of the fixing group 2, an air pump 5 is provided on the upper right part of the fixing group 2, a sliding mechanism 6 is slidably connected to the middle of the upper side of the fixing group 2, and a clamping mechanism 4 is provided on the middle part of the upper side of the sliding mechanism 6.

[0020] It should be noted that the specific installation method of the control panel 3 and the air pump 5, the circuit connection method and the control method in the present invention are all conventional designs and are conventional design means of designers. The control panel 3 includes a control center, switches and a touch screen display, etc., and the air pump 5 is controlled by the control panel 3.

[0021] First, the staff member holds the handle 1 to pick up the whole device, and puts the fixing group 2 on the appropriate position of the head of the angiography bed, and then controls the air pump 5 through the control panel 3. The air pump 5 blows gas into the fixing group 2 to fix the fixing group 2 on the angiography bed. Then, the patient lies on the angiography bed with his head resting on the clamping mechanism 4. The clamping mechanism 4 can fix the head of different patients. At the same time, the clamping mechanism 4 will also record the pressure value of the patient's head fixation, and feedback to the control panel 3 for display, so that the medical staff can refer to it when fixing the next patient's head. At the same time, the sliding mechanism 6 can be adjusted to make the clamping mechanism 4 rotate left and right within a certain range on the sliding mechanism 6, and it can be adjusted according to needs to facilitate angiography of the cerebral blood vessels in the patient's head.

[0022] In order to enable the device to be quickly fixed on the imaging bed, Figure 3 and Figure 4 As shown, the fixing group 1 2 includes a sliding frame 21, and the left and right sides of the bottom wall of the inner cavity of the sliding frame 21 are provided with mounting grooves 1 22, and the inner cavities of the two mounting grooves 1 22 are fixedly connected with air bags 23, and the middle part of the upper end of the sliding frame 21 is provided with a left-right symmetrical sliding groove 1 24, and the rear side of the middle part of the upper end of the sliding frame 21 is provided with a mounting groove 28, and the left and right sides of the bottom wall of the mounting groove 28 are fixedly connected with springs 29, and the upper ends of the two springs 29 are fixedly connected with a bayonet 25, and the middle part of the lower end of the bayonet 25 is fixedly connected with a pressure block 26. The outer surface of the latch 25 and the outer surface of the pressure block 26 are slidably connected to the inner cavity of the second mounting groove 28. An air column 27 is fixedly connected to the left side of the middle of the upper end of the sliding frame 21, and the inner cavity of the air column 27 is communicated with the inner cavities of the two air bags 23 through an air pipe. The lower ends of the two handles 1 are respectively fixedly connected to the left and right sides of the middle of the upper end of the sliding frame 21. The lower end of the control panel 3 is fixed to the left rear part of the upper end of the sliding frame 21. The lower end of the air pump 5 is fixedly connected to the right front part of the upper end of the sliding frame 21, and the output end of the air pump 5 is fixedly connected to the upper end of the air column 27.

[0023] First, the sliding mechanism 6 is stuck in the inner cavity of the two sliding grooves 24 and slides forward. During the sliding process, the latch 25 is squeezed, so that the latch 25 drives the pressure block 26 to slide downward in the inner cavity of the installation groove 28 and compresses the two springs 29. The sliding mechanism 6 moves forward to a suitable position in the inner cavity of the sliding groove 24. The sliding mechanism 6 no longer squeezes the latch 25. Under the elastic force of the spring 29, the latch 25 moves upward in the inner cavity of the installation groove 28, so that the sliding mechanism 6 is stuck in the sliding groove 24 to achieve a fixed effect. If the sliding mechanism 6 needs to be quickly disassembled from the fixing group 2, it only needs to press the pressure block 26 to make the pressure block 26 The latch 25 is driven to move downward in the inner cavity of the second installation groove 28, and the sliding mechanism 6 is then pulled out from the inner cavity of the sliding groove 1 24. When the device needs to be installed on the angiography bed, the sliding frame 21 is put on the appropriate position of the head of the angiography bed through the handle 1, and then the air pump 5 is controlled by the control panel 3. The air pump 5 blows gas into the airbag 23 through the air column 27, so that the airbag 23 expands rapidly and presses against the bottom of the bed board of the angiography bed. With the cooperation of the sliding frame 21, the entire device is fixed on the angiography bed, and finally the purpose of enabling the device to be quickly fixed on the angiography bed is achieved, and its stability is higher than that of the same type of device directly placed on the angiography bed.

[0024] In order to facilitate the purpose of rotating and adjusting the clamping mechanism 4 in the left and right directions, as shown in FIG. Figure 5 As shown, the sliding mechanism 6 includes a T-shaped slide bar 62 which is respectively slidably connected to the inner cavities of the two sliding grooves 24, the upper ends of the two T-shaped slide bars 62 are commonly fixedly connected to a U-shaped plate 61, the middle part of the upper side of the U-shaped plate 61 is fixedly connected to a sliding group 63, the front side of the right wall of the inner cavity of the U-shaped plate 61 is fixedly connected to a rotating frame 65, the inner cavity of the rotating frame 65 is rotatably connected to a rotating handle 64, and the rear end of the rotating handle 64 is fixedly connected to the front right part of the sliding group 63.

[0025] First, when the sliding mechanism 6 is installed on the fixed group 2, the T-shaped slide bar 62 slides in the inner cavity of the sliding groove 24, and the U-shaped plate 61 presses the pin 25, and finally completes the quick installation operation. When the patient's head is fixed in the clamping mechanism 4 and needs to be rotated left and right, the rotating handle 64 is rotated, and the rotating frame 65 supports the rotating handle 64, but does not affect the rotation of the rotating handle 64 itself. By rotating the rotating handle 64, the clamping mechanism 4 installed in the sliding group 63 is adjusted, so that the clamping mechanism 4 can be rotated left and right within a certain range in the sliding group 63, thereby achieving the purpose of facilitating the rotation adjustment of the clamping mechanism 4 in the left and right directions, and facilitating angiography of the cerebral blood vessels in the patient's head.

[0026] Further explanation, such as Figure 6 and Figure 7As shown, the sliding group 63 includes a connecting plate 631, and the left and right ends of the connecting plate 631 are fixedly connected to an arc-shaped slot plate 632. The upper parts of the two arc-shaped slot plates 632 that are away from each other are provided with a slot 636. A U-shaped plate 637 is fixedly connected to the middle of the outer surface of the left arc-shaped slot plate 632, a U-shaped guard plate 635 is fixedly connected to the middle of the outer surface of the right arc-shaped slot plate 632, and a fixed plate 638 is fixedly connected to the front side of the middle of the arc surface of the right arc-shaped slot plate 632. The inner cavity of the fixed plate 638 A gear 634 is connected to rotate with the U-shaped guard plate 635. The front side of the outer surface of the gear 634 penetrates the U-shaped guard plate 635 and is provided with a limiter 633. The front end of the gear 634 is fixedly connected to the rear end of the rotating handle 64. The lower end of the connecting plate 631 is fixedly connected to the middle of the bottom wall of the inner cavity of the U-shaped plate 61. The two slots 636 are respectively fitted with the left and right sides of the middle of the upper end of the U-shaped plate 61. The slots 636 are provided to facilitate the arc groove plate 632 to be clamped at the upper edge of the U-shaped plate 61 to play a fixing role.

[0027] It should be noted that the specific installation method of the limiter 633, the circuit connection method and the control method in the present invention are all conventional designs, which are conventional design means of designers. The front end of the gear 634 passes through the inner cavity of the limiter 633, and the rotation of the gear 634 is limited by opening and closing the limiter 633.

[0028] In detail, the clamping mechanism 4 is installed in the inner cavities of the two arc-shaped groove plates 632 and between the U-shaped plate 637 and the U-shaped guard plate 635, and can rotate left and right. First, the limiter 633 is opened, and then the rotating handle 64 is rotated to drive the gear 634 to rotate between the inner cavities of the U-shaped guard plate 635 and the fixed plate 638. The rotation of the gear 634 is used to rotate the clamping mechanism 4 in the left and right directions to a suitable position, and the limiter 633 is closed to limit the rotation of the gear 634, thereby fixing the clamping mechanism 4 with the adjusted angle, thereby achieving the rotation adjustment of the clamping mechanism 4 in the left and right directions.

[0029] Embodiment 2: Based on Embodiment 1, this embodiment implements fixing the heads of different patients, such as Figure 8 As shown, the clamping mechanism 4 includes a headrest 41, a pillowcase 42 is provided on the upper side of the outer surface of the headrest 41, a lifting group 44 is fixedly connected to the lower part of the left and right sides of the headrest 41, a slide plate 43 is fixedly connected to the lower part of the side away from each other of the two lifting groups 44, an arc-shaped rack 46 is fixedly connected to the lower part of the front side of the right lifting group 44, a clamping group 45 is provided on the upper side of the two lifting groups 44, the outer surfaces of the two slide plates 43 are respectively slidably connected to the inner cavities of the two arc-shaped groove plates 632, and the outer surface of the arc-shaped rack 46 is meshingly connected to the outer surface of the gear 634.

[0030] First, the patient's head rests on the pillowcase 42 installed on the upper side of the headrest 41, and the pillowcase 42 can be quickly replaced and disinfected for the next patient to use, saving the operation time of medical staff. Then, the height of the clamping group 45 installed thereon is adjusted to a suitable position through the lifting groups 44 on the left and right sides. Finally, the heads of different patients can be fixed by rotating the clamping groups 45 on the left and right sides, and the pressure value after the head is fixed is recorded and fed back to the control panel 3. When the gear 634 rotates, it will drive the arc rack 46 to rotate. 6 rotates, thereby driving the lifting group 44 and the slide plate 43 fixedly connected thereto to slide between the U-shaped guard plate 635 and the inner cavity of the arc-shaped groove plate 632 on the left side, and thereby driving the lifting group 44 and the slide plate 43 on the right side to slide between the U-shaped plate 637 and the inner cavity of the arc-shaped groove plate 632 on the left side through the headrest 41. When the limiter 633 closes and restricts the rotation of the gear 634, it plays a role in fixing the clamping mechanism 4 that has been adjusted to a good position, and ultimately achieves the purpose of fixing the heads of different patients and adjusting them in the left and right directions through the coordinated use of the sliding mechanism 6.

[0031] Further explanation, such as Fig. 9 and Fig.10 As shown, the two lifting groups 44 each include a side plate 441, an electric telescopic rod 442 is provided in the middle of the upper ends of the two side plates 441, a support plate 443 is slidably connected to the front and rear sides of the inner cavities of the two side plates 441, the upper ends of the two support plates 443 on the same side and the output ends of the electric telescopic rod 442 are commonly fixedly connected to a support plate 445, a threaded hole 446 is provided in the middle of the lower sides of the opposite surfaces of the two support plates 445, a front-to-back symmetrical sliding hole 444 is provided on the lower sides of the opposite surfaces of the two support plates 445, and a sensor 447 is provided on the upper rear sides of the opposite surfaces of the two side plates 441.

[0032] It should be noted that the specific installation method, circuit connection method and control method of the electric telescopic rod 442 and the sensor 447 in the present invention are all conventional designs, which are conventional design means of designers. The sensor 447 is composed of electronic components such as infrared sensors and controllers, which are controlled by the control panel 3, and the sensor 447 can control the electric telescopic rod 442.

[0033] In detail, when the patient's head is resting on the pillowcase 42, the left and right sides of the patient's head are scanned up and down through the sensors 447 on the left and right sides, and the electric telescopic rod 442 is controlled to drive the support plate 445 to move up and down to a suitable position with the cooperation of the support plate 443, so that the clamping mechanism 4 is aligned with the suitable positions on both sides of the patient's head, and with the cooperation of the sliding hole 444 and the threaded hole 446, the clamping groups 45 on the left and right sides are rotated to move the two clamping groups 45 toward the middle, so that the heads of different patients can be fixed, thereby achieving the purpose of fixing the head.

[0034] Further explanation, such as Fig.11 As shown, the two clamping groups 45 each include a knob 451, a threaded rod 452 is fixedly connected to the middle of the opposite surfaces of the two knobs 451, a rotating groove 454 is opened in the middle of the opposite surfaces of the two threaded rods 452, the inner cavities of the two rotating grooves 454 are rotatably connected to T-shaped rotating rods 455, the opposite surfaces of the two T-shaped rotating rods 455 are fixedly connected to clamping blocks 456, the ends of the two clamping blocks 456 away from each other are fixedly connected to front-to-back symmetrical support rods 453, the opposite surfaces of the two clamping blocks 456 are provided with front-to-back symmetrical sensors 458, the outer surfaces of the two clamping blocks 456 are slidably connected to the clamping sleeves 457, the outer surfaces of the two support rods 453 on the same side are respectively slidably connected to the inner cavities of the two sliding holes 444, and the outer surfaces of the threaded rods 452 on the same side are meshedly connected to the inner cavities of the threaded holes 446.

[0035] It should be noted that the specific installation method of sensor 2 458, the circuit connection method and the control method in the present invention are all conventional designs and are conventional design means of designers. Sensor 2 458 is composed of electronic components such as pressure sensing elements and signal devices, and sensor 2 458 is used in conjunction with control panel 3.

[0036] In detail, by rotating the knobs 451 on the left and right sides, the knobs 451 on the left and right sides drive the threaded rod 452 fixedly connected thereto to rotate in the inner cavity of the threaded hole 446 on the same side, and with the coordinated use of the support rod 453 and the sliding hole 444, the inner cavity of the rotating groove 2 454 rotates on the surface of the T-shaped rotating rod 455, while pushing the T-shaped rotating rod 455 to drive the clamping block 456 to move to a suitable position toward the patient's head, and in the process of fixing the patient's head, the jackets 457 on the left and right sides slide away from each other on the surface of the clamping block 456, and compress the sensor 2 458 on the same side. After the patient's head is fixed, the sensor 2 458 records the pressure value at the moment and feeds it back to the control panel 3, and displays it, so that the medical staff can refer to it for subsequent operations and determine the pressure value required for fixing the head of different patients, and the jacket 457 can be detached from the clamping block 456 for rapid replacement and disinfection, so as to facilitate the use of the next patient and reduce the operation time of the medical staff.
