Description

Technical Field

[0001] This utility model relates to the field of catheterization technology, and in particular to a catheterization bed. 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 front-to-back and left-to-right tilt adjustment and relative position movement. The bed board of the catheterization bed has a movement stroke of 1200mm, and the entire base of the catheterization bed is installed on a moving track platform and can move as a whole by 1000mm, thus meeting the needs of large stroke movement adjustment.

[0004] The bed board needs to slide flexibly after bearing the patient. The existing bed board achieves sliding support through sliding guide rails. After the bed board bears the load, it will produce a certain bending deformation, which will cause the relative sliding of the bed board to generate resistance and reduce flexibility. Utility Model Content

[0005] The purpose of this invention is to provide a catheter bed that optimizes the sliding guide rail structure to avoid deformation and maintain flexible sliding when the bed plate is under load.

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

[0007] A catheterization bed includes a lifting and rotating base, on which linear guide rails are spaced apart. A transverse frame that slides along a first direction is slidably mounted on the linear guide rails. A guide rail mechanism and a bed board mounted on the guide rail mechanism are mounted on the transverse frame. A belt drive mechanism is provided on the transverse frame, which pulls the bed board to slide relative to the guide rail mechanism along a second direction, where the first direction is perpendicular to the second direction. The guide rail mechanism includes four eccentric wheel sliders spaced apart on both sides of the transverse frame. Two eccentric wheel sliders on the same side are each slidably mounted with a sliding rail. A track plate is fixed on the two sliding rails, and the bed board is fixed on the track plate.

[0008] Preferably, the eccentric wheel slider includes a mounting block fixed on the transverse frame, three first rotating wheels are rotatably mounted on the mounting block, and a second rotating wheel located between two adjacent first rotating wheels is rotatably mounted on the mounting block; the top of the first rotating wheel is higher than the top of the second rotating wheel, and the bottom of the second rotating wheel is lower than the bottom of the first rotating wheel.

[0009] Preferably, both ends of the mounting block are provided with limiting baffles.

[0010] Preferably, the sliding track has a sliding groove, and the side wall of the sliding groove has an engaging groove, and the rims of the first rotating wheel and the second rotating wheel roll into the engaging groove.

[0011] Preferably, the belt drive mechanism includes a motor mounted on the transverse frame, a pulley mounted on the motor shaft, a transmission belt sleeved on the pulley, and both ends of the transmission belt fixed to the track plate; the transverse frame is also provided with a brake motor, a first brake gear mounted on the shaft of the brake motor, and a second brake gear connected to the pulley and cooperating with the first brake gear.

[0012] Preferably, sheet metal parts are fixed at both ends of the transmission belt, and the sheet metal parts are fixed to the track plate.

[0013] Preferably, a support column is installed on the transverse frame away from the transmission belt, a support block is fixed on the support column, and the bed board is slidably engaged with the support block.

[0014] Preferably, the bed board is provided with armrests on both sides.

[0015] Beneficial effects:

[0016] In the guide rail mechanism of the catheter bed, four eccentric wheel sliders are spaced apart on both sides of the transverse frame. Two eccentric wheel sliders on the same side support the sliding guide rail to slide flexibly. After the bed board is fixed to the sliding guide rail by the track plate, it is fixed. Thus, the bed board supports the sliding rail through the eccentric wheel sliders, which can meet the requirements of flexible sliding during the sliding process. After the eccentric wheel sliders stably support the sliding guide rail, the bed board is fixed by the track plate without deformation, thus achieving stable sliding of the bed board.

[0024] 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.

[0025] See Figures 1-5 As shown in the figure, an embodiment of this utility model proposes a catheterization bed, including a lifting and rotating base 1. Linear guide rails 2 are installed at intervals on the lifting and rotating base 1. A transverse sliding frame 3 that slides along a first direction is slidably installed on the linear guide rails 2. A guide rail mechanism 4 and a bed board 5 installed on the guide rail mechanism 4 are installed on the transverse sliding frame 3. A belt drive mechanism 6 is provided on the transverse sliding frame 3. The belt drive mechanism 6 pulls the bed board 5 to slide relative to the guide rail mechanism 4 along a second direction. The first direction is perpendicular to the second direction. The lifting and rotating base 1 can realize lifting and rotation angle adjustment, which is the existing technology used in catheterization beds. The linear guide rails 2 are mainly used to realize the sliding of the bed board 5 in the transverse direction, while the guide rail mechanism 4 is used to realize the sliding of the bed board 5 in the length direction, so that the bed board 5 can move relative to the other side during actual use.

[0026] The guide rail mechanism 4 primarily serves as the sliding adjustment mechanism for the bed board 5 under load. Existing structures suffer from damping during sliding due to deformation of the bed board 5, resulting in inflexible sliding. Therefore, the guide rail mechanism 4 is improved to maintain flexible sliding while preventing deformation of the sliding parts of the bed board 5. Specifically, the guide rail mechanism 4 includes four eccentric wheel sliders 41 spaced apart on both sides of the transverse frame 3. Two eccentric wheel sliders 41 on the same side are slidably mounted with sliding rails 42. Track plates 43 are fixed to the two sliding rails 42, and the bed board 5 is fixed to the track plates 43. The eccentric wheel sliders 41 maintain support contact with the sliding rails 42 during sliding, thus preventing unidirectional deformation of the sliding rails 42 and the resulting sliding damping. Since the sliding rails 42 do not deform, and the bed board 5 is fixed to the sliding rails 42 via the track plates 43, the force under load is transmitted to the eccentric wheel sliders 41 through the sliding rails 42, preventing deformation of the bed board 5 and achieving flexible adjustment under load.

[0027] Specifically, the eccentric wheel slider 41 includes a mounting block 411 fixed on the transverse frame 3. Three first rotating wheels 412 are rotatably mounted on the mounting block 411, and a second rotating wheel 413 located between two adjacent first rotating wheels 412 is rotatably mounted on the mounting block 411. The top of the first rotating wheel 412 is higher than the top of the second rotating wheel 413, and the bottom of the second rotating wheel 413 is lower than the bottom of the first rotating wheel 412. This makes the rotation axis of the first rotating wheel 412 and the rotation axis of the second rotating wheel 413 eccentrically set, thereby ensuring that the sliding track 42 contacts at least the first rotating wheel 412 and the second rotating wheel 413 during the sliding process. By maintaining contact, the deformation of the sliding track 42 can be reduced, further preventing the bed board 5 from deforming.

[0028] Meanwhile, limiting baffles 414 are provided at both ends of the mounting block 411. The limiting baffles 414 are used to guide the sliding guide rail and prevent impurities from entering the interior, which could cause the first rotating wheel 412 and the second rotating wheel 413 to get stuck.

[0029] The sliding track 42 is provided with a groove 421, and the side wall of the groove 421 is provided with a locking groove 422. The rims of the first rotating wheel 412 and the second rotating wheel 413 roll into the locking groove 422. The groove 421 accommodates the first rotating wheel 412 and the second rotating wheel 413, and the locking groove 422 limits the rolling engagement of the rims of the first rotating wheel 412 and the second rotating wheel 413, thereby keeping the sliding track 42 in contact with the first rotating wheel 412 and the second rotating wheel 413 and avoiding the risk of falling off.

[0030] Specifically, the belt drive mechanism 6 includes a motor 61 mounted on the transverse frame 3. A pulley 62 is mounted on the shaft of the motor 61, and a transmission belt 63 is fitted onto the pulley 62. The two ends of the transmission belt 63 are fixed to the track plate 43. The motor 61 drives the pulley 62 to rotate, thereby pulling the transmission belt 63 to reciprocate relative to the eccentric wheel slider 41 along the track plate 43, the bed plate 5, and the sliding track 42. At the same time, a brake motor 61 is also provided on the transverse frame 3. A first brake gear 66 is mounted on the shaft of the brake motor 61, and a second brake gear 67 that cooperates with the first brake gear 66 is connected to the pulley 62. After moving to the correct position, the brake motor 61 drives the first stop gear to brake the second brake gear 67, thereby achieving relative position braking. Specifically, the moving stroke of the bed plate 5 is 1200mm, and braking at any position can be achieved within the stroke range.

[0031] Meanwhile, sheet metal parts 64 are fixed at both ends of the transmission belt 63. The sheet metal parts 64 are fixed on the track plate 43. The sheet metal parts 64 facilitate the fastening of both ends of the transmission belt 63 to the track plate 43, which facilitates the assembly operation.

[0032] Specifically, a support column 7 is installed on the transverse frame 3 on the side away from the transmission belt 63. A support block 8 is fixed on the support column 7. The bed board 5 is slidably engaged with the support block 8, and the support block 8 further supports the bed board 5 to prevent deformation after bearing load.

[0033] In order to facilitate the restraint of patients lying on the bed board 5, and also to facilitate the patients' hand grip, handrails 9 are provided on both sides of the bed board 5.
