Description

Technical Field

[0001] This utility model relates to the field of catheterization technology, and in particular to a catheterization bed and its control console. Background Technology

[0002] The hybrid operating room is a comprehensive integration of 3D imaging technology from equipment such as DSA, CT, and MRI with surgery in a Class 100 laminar flow operating room. This allows for the combination of minimally invasive interventional surgery and traditional open surgery, thereby solving various complex surgeries, reducing surgical risks, and saving surgical time.

[0003] The commonly used operating table in a hybrid operating room is a catheterization bed with adjustable tilt in all directions and relative position movement. The bed board of the catheterization bed has a travel range of 1200mm, and the entire base of the catheterization bed is mounted on a moving track platform, which can move 1000mm as a whole. This allows for large-scale movement adjustment. The catheterization bed has multiple angle adjustments, including lifting and rotating drive, lateral drive, and translation drive. The adjustments are all performed through the control panel integrated on the catheterization bed and then automatically adjusted by PLC control.

[0004] Existing control consoles only require moving the handle head to trigger a signal, which can easily lead to misoperation in practical applications. Utility Model Content

[0005] The purpose of this invention is to provide a catheterization bed and its control console, which solves the problem in the prior art where the control signal can be directly triggered when the handle is operated, which easily leads to misoperation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A control panel for a catheter bed includes a lower housing and a mounting plate connected to the lower housing. A handle seat is fixed on the mounting plate. A fisheye bearing and a front shaft passing through the fisheye bearing are installed in the handle seat. An elastic body evenly distributed circumferentially is integrated on the portion of the front shaft extending into the lower housing. A clamping seat is provided on the front shaft to press the elastic body. A set screw and an adjusting position seat are threadedly connected to the clamping seat. A switch seat and a trigger switch integrated in the switch seat are installed on the adjusting position seat. A positioning seat located outside the elastic body is installed in the mounting plate. A plurality of pressure sensors are installed on the positioning seat near the elastic body and located around it. A handle head is connected to the end of the front shaft outside the mounting plate. A trigger rod is slidably provided in the front shaft. The handle head drives the trigger rod to move up and down or swing.

[0008] Preferably, the handle head includes a threaded seat threadedly connected to the handle seat, a tailstock slidably disposed within the threaded seat, the upper end of the trigger rod fixed to the tailstock, the tailstock being connected to the front shaft via a concentric shaft, the concentric shaft pressing against the inner ring of the fisheye bearing; a handle cap is threadedly connected to the tailstock, and a return spring is sleeved on the tailstock between the handle cap and the threaded seat; a silicone limiting ring is sleeved on the concentric shaft, the edge of the silicone limiting ring being pressed against the threaded seat and the handle seat.

[0009] Preferably, a limiting seat is fitted on the handle seat, the limiting seat is fixed to the bottom of the handle cap, and the inner ring of the limiting seat is clearance-fitted with the outer ring of the handle seat; the inner ring diameter of the limiting seat is smaller than the outer ring diameter of the threaded seat.

[0010] Preferably, the handle seat is further provided with a pressure seat for pressing the outer ring of the fisheye bearing.

[0011] Preferably, the positioning seat is provided with an adjusting screw for adjusting the position of the pressure sensor.

[0012] Preferably, a silicone upper shell is fitted onto the mounting plate, and the silicone upper shell is sealed to the lower shell.

[0013] Preferably, the number of pressure sensors is four, arranged at 90° intervals.

[0014] Preferably, the bottom of the lower housing has a through hole, and a circuit board for connecting the pressure sensor and the trigger switch is integrated inside the lower housing. A cable passing through the through hole is integrated on the circuit board.

[0015] This utility model also proposes a catheterization bed, including a control panel for the catheterization bed as described above, thereby avoiding misoperation when operating the catheterization bed.

[0016] Beneficial effects:

[0017] During operation, the handle head needs to be driven to move the trigger rod down and keep it in contact with the trigger switch so that the trigger switch can send a trigger signal. At this time, the handle head is then swung back and forth and left and right to trigger the elastic body and the pressure sensor at the corresponding position to send a control signal. Therefore, when the actual control signal is sent, the handle head needs to be pressed down to keep the trigger switch on while swinging to send a control signal. That is, both the trigger switch and the pressure sensor need to send signals to realize the control. This avoids the situation where touching the pressure sensor directly will trigger the control when there is no operation. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] See Figures 1-3 As shown, an embodiment of this utility model proposes a control console for a catheterization bed, which is integrated into the catheterization bed to generate control signals to adjust the angle, displacement, etc. of the catheterization bed. However, the specific adjustment methods of the catheterization bed are all existing technologies. In the currently used control console, the control signal is generated by directly adjusting the angle after startup, which can easily lead to misoperation. Therefore, in order to avoid the problem of easy misoperation, the control console is improved.

[0025] The improved control console includes a lower shell 1 and a mounting plate 2 connected to the lower shell 1. A handle seat 3 is fixed on the mounting plate 2. A fisheye bearing 4 and a front shaft 5 passing through the fisheye bearing 4 are installed in the handle seat 3. An elastic body 6 is integrated on the part of the front shaft 5 that extends into the lower shell 1. A clamping seat 7 is provided on the front shaft 5 to press the elastic body 6. A set screw and an adjustment position seat are threadedly connected to the clamping seat 7. A switch seat 9 and a trigger switch 10 integrated in the switch seat 9 are installed on the adjustment position seat. The trigger switch 10 is integrated at the end of the front shaft 5 through the integrated switch seat 9. The position of the trigger switch 10 relative to the front shaft 5 can be adjusted by adjusting the set screw to adjust the sensitivity of the trigger switch 10.

[0026] Simultaneously, a positioning seat 11 is installed inside the mounting plate 2, located outside the elastic body 6. Multiple pressure sensors 12 are mounted on the positioning seat 11, close to and surrounding the elastic body 6. To facilitate displacement adjustment in the front-back and left-right directions of the catheter bed, four pressure sensors 12 are arranged at 90° intervals. Furthermore, the positioning seat 11 is equipped with adjusting screws 14 for adjusting the position of the pressure sensors 12. By adjusting the distance between the pressure sensors 12 and the elastic body 6 using the adjusting screws 14, the trigger sensitivity of the pressure sensors 12 can be adjusted.

[0027] When the front axle 5 swings, the elastic body 6 will touch the pressure sensor 12, thereby triggering the corresponding control signal.

[0028] A handle head 13 is connected to the end of the front shaft 5 located outside the mounting plate 2. A trigger rod 17 is slidably provided inside the front shaft 5. The handle head 13 drives the trigger rod 17 to move up and down or swing. When the handle head 13 drives the trigger rod 17 to press down, it can contact the trigger switch 10 to keep the trigger switch 10 in the triggered state. At the same time, by moving the handle head 13 back and forth and swinging the trigger rod 17, the pressure sensor 12 of the elastic body 6 on the front shaft 5 in the corresponding direction is not triggered. Therefore, when operating, both the trigger switch 10 and the pressure sensor 12 need to be triggered at the same time in order to control the catheter bed, thereby avoiding the occurrence of misoperation.

[0029] Specifically, the handle head 13 is mainly used for gripping and operation, enabling the trigger rod 17 to slide up and down and swing with the front shaft 5. The handle head 13 includes a threaded seat 131 threadedly connected to the handle base 3. A tail seat 132 is slidably provided in the threaded seat 131. The upper end of the trigger rod 17 is fixed on the tail seat 132. The tail seat 132 is connected to the front shaft 5 through a concentric shaft 133. The concentric shaft 133 presses the inner ring of the fisheye bearing 4. At the same time, a pressure seat 138 is also provided in the handle base 3 for pressing the outer ring of the fisheye bearing 4, so that after the fisheye bearing 4 is positioned, the inner ring can swing with the front shaft 5 and turn flexibly.

[0030] After connecting the tailstock 132 and the front shaft 5 via a concentric shaft 133, a handle cap 134 is threaded onto the tailstock 132, allowing the handle cap 134 to simultaneously swing the tailstock 132, the concentric shaft 133, and the front shaft 5. The concentric shaft 133 ensures that the tailstock 132 has a relative sliding stroke relative to the front shaft 5. A return spring 135 is fitted onto the tailstock 132 between the handle cap 134 and the threaded seat 131. When the handle cap 134 moves downwards with the tailstock 132 and the trigger rod 17, triggering the switch 10, and then is released, the return spring 135 returns the handle cap 134 to its original position, thus allowing the trigger rod 17 to return to its original position.

[0031] In order to achieve reset after swinging, a silicone limiting ring 136 is fitted on the concentric shaft 133. The edge of the silicone limiting ring 136 is pressed by the threaded seat 131 and the handle seat 3. When swinging, the silicone limiting ring 136 deforms and has a reset elastic force. After releasing the handle cap 134, the reset action is used to reset.

[0032] Meanwhile, in order to prevent the handle cap 134 from detaching from the threaded seat 131 and to limit the corresponding travel, a limiting seat 137 is fitted on the handle seat 3. The limiting seat 137 is fixed to the bottom of the handle cap 134. The inner ring of the limiting seat 137 is in clearance fit with the outer ring of the handle seat 3. The inner ring diameter of the limiting seat 137 is smaller than the outer ring diameter of the threaded seat 131. The limiting seat 137 acts as a blockage, thereby preventing the handle cap 134 from detaching from the threaded seat 131.

[0033] To protect the interior, a silicone upper shell 15 is fitted onto the mounting plate 2. The silicone upper shell 15 is sealed to the lower shell 1, which facilitates the installation of the entire control console onto the guide bed and ensures good waterproof and dustproof performance during use.

[0034] To facilitate internal sealing and to allow wires to be led out from the inside and connected to the PLC control box of the guide bed, a wire hole 16 is provided at the bottom of the lower shell 1. The lower shell 1 integrates a circuit board that connects the pressure sensor 12 and the trigger switch 10. The circuit board integrates a cable that passes through the wire hole 16. The cable passing through the wire hole 16 is pressed and sealed to ensure the stability of the cable connection.

[0035] Based on the above embodiments, a catheterization bed is also proposed, including a control console for a catheterization bed as described in the above embodiments. After the control console is connected to the PLC control box of the catheterization bed, the control information generated by the operation is used to adjust the catheterization bed.
