[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0020] The multi-degree-of-freedom brain tissue support disclosed in this invention is mainly used in brain tissue supports where the multi-degree-of-freedom support is fixedly installed. Therefore, it may obstruct medical personnel during surgery, hindering their medical operations and thus affecting the surgical process.
[0021] Reference Figures 1-7 A multi-degree-of-freedom brain tissue support for neurosurgery, comprising: A multi-degree-of-freedom support body 1, with a bracket seat 2 provided at one end of the multi-degree-of-freedom support body 1; Bracket plate 3 is disposed on one outer wall of bracket base 2; The padding layer 4 is located on top of the bracket plate 3 and is used to increase patient comfort. Surgical fixation module 5 is mounted on bracket seat 2. Surgical fixation module 5 is used to fix the patient's head and adjust the pressure distribution of the skull contact surface in a timely manner. The offset obstruction module 6 is installed on the bracket base 2 and the multi-degree-of-freedom stent body 1. The offset obstruction module 6 is used to adjust the fixed position of the multi-degree-of-freedom stent body 1 to avoid obstruction of medical operations.
[0022] Reference Figures 1-5 In a preferred embodiment, the offset obstruction module 6 includes: Guide rail seat 601 is located below the multi-degree-of-freedom support body 1, and a linear lead screw 609 is installed inside the guide rail seat 601. Movable block seat 610 is mounted on guide rail seat 601 and linear lead screw 609, and multi-degree-of-freedom bracket body 1 is fixedly connected to the top of movable block seat 610.
[0023] In this invention, the offset obstruction module 6 further includes: Two fixed frames 607 are provided on one side of the outer wall of the guide rail seat 601. A hydraulic cylinder 606 is provided on each of the two fixed frames 607. A clamping plate 608 is fixedly connected to the output end of each of the two hydraulic cylinders 606. Stepper motor 605 is mounted on one side of the outer wall of guide rail 601. The output shaft of stepper motor 605 is connected to one end of linear lead screw 609 via a coupling.
[0024] In this invention, the offset obstruction module 6 further includes: A fixed bracket 602 is fixedly connected to the top of two fixed frames 607. An electric push rod 603 is fixedly connected to the fixed bracket 602. A fixed plate base 604 is fixedly connected to the output end of the electric push rod 603. A fixed ring frame 617 is installed on the outer wall of the bracket seat 2. An electric telescopic rod 616 is installed on the fixed ring frame 617, and the output end of the electric telescopic rod 616 is fixedly connected to the installation platform 618.
[0025] In this invention, the offset obstruction module 6 further includes: Two fixing screws 612 are provided on the fixing plate base 604; Two threaded sleeves 613 are provided at the bottom of the mounting platform 618, and the two threaded sleeves 613 are respectively provided on the outer wall of the two fixing screws 612.
[0026] In this invention, the offset obstruction module 6 further includes: Two drive sprockets 614 are respectively disposed on the outer wall of the two threaded sleeve rods 613, and both drive sprockets 614 are located below the mounting platform 618; Servo motor 615 is mounted on the top of mounting platform 618. The output shaft of servo motor 615 is connected to linkage sprocket 611 via coupling. A transmission chain belt 619 is provided between linkage sprocket 611 and two transmission sprockets 614.
[0027] Specifically, in use, the fixed frame 607 is set on the operating table. The hydraulic cylinder 606 moves the clamping plate 608 and fixes the device. When the multi-degree-of-freedom support needs to be moved, the electric telescopic rod 616 is activated. The electric telescopic rod 616 drives the installation platform 618 to descend. At the same time as the descent, the servo motor 615 is activated, which drives the linkage sprocket 611 to rotate. This, in turn, works with the transmission chain belt 619 to drive the two transmission sprockets 614 to run synchronously. At this time, the transmission sprockets 614 can drive the threaded sleeve rod 613 to rotate. As it descends, it connects with the fixed screw 612, thereby fixing the position of the bracket seat 2. Then, the stepper motor 605 runs, which drives the linear screw 609 to rotate. This causes the movable block seat 610 to move the multi-degree-of-freedom support body 1. The movement of the multi-degree-of-freedom support body 1 changes its fixing point and further changes the position of its support arm to avoid obstructing medical personnel. In specific application scenarios, the offset obstruction module 6 is suitable for neurosurgical procedures. When in use, the offset obstruction module 6 can adjust the fixed point of the multi-degree-of-freedom stent according to the surgical operation position of the medical personnel, thereby shifting it to avoid obstructing the medical operation and reducing the adverse effects of the stent on the medical operation. At the same time, it can also be adjusted as needed during the operation. When adjusting during the operation, the device can ensure that the position of the bracket plate 3 and the bracket seat 2 will not shift and ensure that the patient will not be harmed by the shift, thereby increasing the stability and safety of the device. It should be noted that the guide rail base 601, linear lead screw 609 and stepper motor 605 can further improve the degree of freedom of the multi-degree-of-freedom support body 1 and meet the diverse needs during the operation.
[0028] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 In a preferred embodiment, the surgical fixation module 5 includes: Guide rod 501 is fixedly connected to bracket 2, and two movable bases 507 are movably connected to the outer wall of guide rod 501. Two locking handwheels 502 are respectively disposed at one end of the two movable bases 507. The locking handwheels 502 are used to lock and fix the movable bases 507.
[0029] In this invention, the surgical fixation module 5 further includes: Two fixed clamps 506 are fixedly connected to two movable bases 507 respectively. Multi-zone airbags 503 are provided on the outer wall of the opposite side of the two fixed clamps 506. Two receiving control components 511 are respectively disposed on one side of the outer wall of the two fixed clamps 506, and two sensing lines 504 are disposed on one side of the outer wall of each of the two receiving control components 511.
[0030] In this invention, the surgical fixation module 5 further includes: Multiple pressure sensor pads 505 are connected in series with four sensing lines 504, and the multiple pressure sensor pads 505 are respectively disposed on the outer wall of opposite sides of the two multi-zone airbags 503. Two air pump bodies 512 are respectively installed on one side of the outer wall of the two fixed clamps 506, and each side of the outer wall of the two air pump bodies 512 is provided with a delivery pipe 513.
[0031] In this invention, the surgical fixation module 5 further includes: Two connecting chambers 510 are respectively disposed on one side of the outer wall of the two fixed clamps 506, and one end of the two connecting chambers 510 is connected to one end of the two conveying pipes 513 respectively. Multiple connecting pipes 508 are provided, one end of each connecting pipe 508 is respectively set on two connecting chambers 510, and a control valve 509 is provided on the outer wall of each connecting pipe 508. The other end of each connecting pipe 508 is respectively connected to the interior of two multi-zone airbags 503.
[0032] Specifically, when fixing the patient, the patient's head is located on the pad 4. At this time, the movable base 507 is moved. After the movable base 507 moves the fixing clamp 506 to the appropriate position, the movable base 507 is locked and fixed by the locking handwheel 502. At this time, the air pump body 512 runs and delivers gas to the inside of the connecting chamber 510 through the delivery pipe 513, and further delivers it to the inside of the multi-zone airbag 503 through the connecting pipe 508. After the inflation and fixation are completed, the control valve 509 is closed. Then the pressure sensor 505 and the receiving control component 511 run to detect the pressure status of the patient's skull contact surface in real time. If the pressure is insufficient or too high, the control valve 509 and the air pump body 512 are opened as needed to perform the deflation and inflation operations. In specific application scenarios, the surgical fixation module 5 is suitable for the patient's head fixation process. That is, when the surgical fixation module 5 is used, it can fix the patient's head to prevent the patient from moving unconsciously during the operation and causing safety hazards. At the same time, the surgical fixation module 5 can be adjusted according to the size of the patient's head, which improves the applicability of the device and increases the effectiveness of the device. During the surgical fixation, the device uses a pressure sensor 505 to monitor the pressure on the patient's head in real time. When the pressure on the patient's head area is insufficient or excessive, it can adjust the pressure of the skull contact surface in a timely manner to avoid injury to the patient and improve the patient's surgical comfort. It should be noted that the multi-zone airbag 503 has multiple individual air chambers inside, and the pressure in each individual air chamber can be adjusted according to pressure feedback during use.
[0033] Working principle: When in use, the fixed frame 607 is set on the operating table, and the hydraulic cylinder 606 drives the clamping plate 608 to move and fix the device. When the patient is fixed, the patient's head is placed on the pad 4. At this time, the movable base 507 is moved. After the movable base 507 moves the fixing clamp 506 to the appropriate position, the movable base 507 is locked and fixed by the locking handwheel 502. At this time, the air pump body 512 runs and delivers gas to the inside of the connecting chamber 510 through the delivery pipe 513, and further delivers it to the inside of the multi-zone airbag 503 through the connecting pipe 508. After the inflation and fixation are completed, the control valve 509 is closed. Then the pressure sensor 505 and the receiving control component 511 run to detect the pressure status of the patient's skull contact surface in real time. If the pressure is insufficient or too high, the control valve 509 and the air pump body 512 are opened as needed to perform the deflation and inflation operations. When the multi-degree-of-freedom support needs to be moved, the electric telescopic rod 616 is activated, which drives the installation platform 618 to descend. At the same time as the descent, the servo motor 615 is activated, causing the linkage sprocket 611 to rotate. This, in turn, works with the transmission belt 619 to drive the two transmission sprockets 614 to run synchronously. At this time, the transmission sprockets 614 can drive the threaded sleeve rod 613 to rotate, and as it descends, it connects with the fixing screw 612, thereby fixing the position of the bracket seat 2. Then, the stepper motor 605 runs, driving the linear lead screw 609 to rotate, which causes the movable block seat 610 to move the multi-degree-of-freedom support body 1. This movement of the multi-degree-of-freedom support body 1 changes its fixing point and further changes the position of its support arm to avoid obstructing medical personnel.
