Description

Technical Field

[0001] The present application belongs to the technical field of operating tables, and specifically relates to a multifunctional ophthalmic operating table with adjustable head and body position and auxiliary equipment. Background Art

[0002] Ophthalmic surgery is highly dependent on the precise coordination of the patient's head position and the microscope angle. For example, during gonioscopic goniolysis for the treatment of primary angle-closure glaucoma, the surgical orientation of the eye needs to be selected based on the site of adhesion at the angle of the affected eye and the surgeon's preferred position during surgery. The head needs to be tilted 30 to 40 degrees toward the nasal or temporal side to allow for direct visualization of the angle structure under the gonioscope. During vitrectomy, head position adjustment and eye rotation may be required to position the eye into a specific fundus area for easier surgical operation. During cataract surgery, a slight head tilt is occasionally required to prevent the bridge of the nose or brow arch from blocking the intraoperative field of view.

[0003] In the existing technology, when treating patients with hunchbacks or spinal deformities, the existing operating tables cannot adaptively compensate, which can easily lead to the deviation of the surgical field of view due to body position deformation. In addition, during ophthalmic surface anesthesia surgery, it is usually necessary to fix the head position to prevent lateral movement of the head and face, so as to reduce the surgical risk. However, since the existing ophthalmic operating tables are mostly ordinary operating tables with simple headrests installed, the adjustment methods are single (such as mechanical knobs or manual gaskets), and the manual adjustment steps are cumbersome, it is difficult to achieve real-time fine-tuning during the operation. Although the electric operating table can be tilted as a whole, the independent adjustment ability of the head and body position is poor, which cannot meet the multi-angle requirements of ophthalmic surgery. In addition, the traditional headrest is made of hard materials and lacks ergonomic support. Long-term fixation can easily lead to cervical fatigue and even postoperative soreness.

[0004] In response to the above problems, this application designs a multifunctional ophthalmic operating table with adjustable head position and auxiliary equipment to solve technical problems such as surgical field of view deviation easily caused by body position deformation, cumbersome head position adjustment steps during surgery, poor surgical field of view exposure, and long-term surgery that can easily lead to cervical fatigue. Summary of the Invention

[0006] To this end, this application designs a multifunctional ophthalmic operating table with adjustable head position and auxiliary equipment to prevent the surgical field of view from being shifted due to body position deformation.

DETAILED DESCRIPTION

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0022] Refer to the following Figures 1 to 16 The present invention describes a multifunctional ophthalmic operating table with adjustable head position and auxiliary tools provided in some embodiments of the present application.

[0023] See also Figures 1 to 16 The multifunctional ophthalmic operating table with adjustable head and body position and auxiliary equipment provided in some embodiments of the present application includes: a bed body 1; five back honeycomb air cushions 3, which are arranged on the surface of the bed body 1 from left to right; a lumbar support adjustment component, which is arranged below the back honeycomb air cushion 3 and is used to adjust the support force of the back honeycomb air cushion 3 on the patient's spine. The lumbar support adjustment component includes: a lower pressure sensor 302, the surface of the bed body 1 is provided with five movable grooves 301 arranged in sequence from left to right, and the lower pressure sensors 302 are fixed one by one to the bottom of the movable grooves 301; a first hydraulic cylinder 303, which is connected to the lower pressure The force sensor 302 is the power end; the support plate 304 is fixed to the power end of the first hydraulic cylinder 303, and the back honeycomb air cushion 3 is connected to the upper end of the support plate 304; the first air pump 305 is fixed in the movable groove 301; the first air pipe 306, one end of which is connected to the air delivery port of the first air pump 305, and the other end of the first air pipe 306 is connected to the back honeycomb air cushion 3; the first solenoid valve 307 is fixed to the lower end of the support plate 304 and is connected to the back honeycomb air cushion 3; the alarm 308 and the controller 309 are both fixed in the movable groove 301, and the foot reset switch 24 is arranged under the bed body 1.

[0024] By setting five back honeycomb air cushions 3, the back support of the operating bed adopts a five-stage independent hydraulic lifting mode, and the back honeycomb air cushion 3 can be raised and lowered by the extension and contraction of the first hydraulic cylinder 303. When a hunchback patient lies on the bed body 1, the back honeycomb air cushion 3 supports the patient's back, and the degree of the patient's spinal curvature can be detected by the lower pressure sensor 302. If the pressures felt by the lower pressure sensors 302 are inconsistent at this time, the lower pressure sensor 302 is set to be connected to the signal of the first hydraulic cylinder 303, and the electrical signal of the lower pressure sensor 302 is transmitted to the first hydraulic cylinder 303. The first hydraulic cylinder 303 automatically extends and contracts, and the support plate 304 and the back honeycomb air cushion 3 move up and down, thereby automatically adjusting the pressure of each section of the back honeycomb The height of the air cushion 3 is adjusted until the five lower pressure sensors 302 are evenly pressurized, which is beneficial to gradually correcting the spine of the hunchback patient to a nearly lying state, and supporting the patient's back through the back honeycomb air cushion 3. The lower pressure sensor 302 is beneficial to real-time detection of local pressure. When the first air pump 305 is working, it is beneficial to inflate the back honeycomb air cushion 3 through the first air supply pipe 306 and the first air inlet pipe, thereby adjusting the inflation volume of the back honeycomb air cushion 3 to make the pressure of the back honeycomb air cushion 3 ≤25kPa. If it is greater than 25kPa, the first solenoid valve 307 is automatically opened at this time to achieve a timely pressure relief effect, thereby dispersing the force to avoid pressure sores. In summary, it is beneficial to solve the situation where the surgical field of view is offset due to body position deformation, and effectively expands the range of surgical indications.

[0025] The implementation steps are as follows: After the patient lies flat, the five-segment lumbar support adjustment component on the back starts the initial posture scan (the lower pressure sensor 302 matrix detects the spinal curvature distribution at a frequency of 10Hz). The patient's kyphosis angle is calculated based on the pressure difference between adjacent segments (typical range of 45°-65°), and the initial lifting parameters of each hydraulic segment are generated (for example, the thoracic spine segment is corrected first). Dynamic correction is performed in stages and is set as follows: Stage 1: Step-by-step lifting: Gradually lift each segment (single lift ≤ 3 cm, interval ≥ 5 seconds), and adjust the height difference between adjacent segments through dynamic feedback of spinal curvature (the mid-segment is lifted first, and the lumbar segment is slightly lowered by 2-3 cm to avoid compensatory stress in the lumbar spine); Phase 2: Pressure balance: After each lift, the honeycomb air cushion 3 on the back is triggered to inflate for compensation (the inflation flow rate in the low-pressure area is 2L / min, and the pressure in the high-pressure area is released to 20kPa), achieving dynamic equalization of local pressure during the correction process (pressure standard deviation ≤ 3kPa).

[0026] Safety control and termination conditions are set as: Abnormal pressure interruption: If the single-stage pressure suddenly increases by 40 kPa or more (due to patient displacement or uncomfortable body position), the hydraulic lock is triggered and started. The lower pressure sensor 302 transmits an electrical signal to the controller 309, and the controller 309 transmits the signal to the alarm 308, which then issues an alarm. Correction completion judgment: When the spinal curvature is ≤15° and the overall pressure uniformity meets the standard (full-segment pressure fluctuation ≤15%), it will automatically switch to the maintenance mode; Emergency reset during surgery: When abnormal physical signs occur during surgery, the foot reset switch 24 is set to be electrically connected to the first solenoid valve 307 and the first hydraulic cylinder 303. Stepping on the foot reset switch 24 can directly trigger a rapid reset (by default, the hydraulic section of the first hydraulic cylinder 303 is forced to return to its position within 3 seconds, and the pressure relief rate of the back honeycomb air cushion 3 is increased to 5L / s), effectively reducing safety hazards during surgery.

[0027] In some embodiments, a bracket 2 is provided under the bed 1 , an installation slot 201 is provided at the upper end of the bracket 2 , a second hydraulic cylinder 202 is fixed in the installation slot 201 , and the lower end of the bed 1 is fixed to the power end of the second hydraulic cylinder 202 .

[0028] In this embodiment, the extension and retraction of the second hydraulic cylinder 202 facilitates the convenient adjustment of the height of the bed 1 , thereby facilitating treatment for patients with shorter heights while lying on the bed 1 .

[0029] In some embodiments, the concave head support 4 is provided on the right side of the bed 1; the headrest airbag 401 is connected to the inner wall of the concave head support 4; the first air pressure regulating component is provided on the outer side of the concave head support 4, and is used to adjust the clamping pressure of the headrest airbag 401 on the patient's head; the three side pressure sensors 9 are all connected to the inner wall of the headrest airbag 401; the first air pressure regulating component includes: a side air pump 6, fixed to the outer side of the concave head support 4; a side air supply pipe 601, connected to the air supply port of the side air pump 6; a side solenoid valve 602, connected to the end of the side air supply pipe 601; a side air inlet pipe 603, one end of which is connected to the side air supply pipe 601 and one side, and the other end of the side air inlet pipe 603 is connected to the headrest airbag 401.

[0030] In this embodiment, the side air pump 6 works, and then the side air supply pipe 601 and the side air inlet pipe 603 are used to inflate the headrest airbag 401, which is conducive to flexible clamping and positioning of the patient's head. Therefore, by inflating the headrest airbag 401, the patient's head position is adjusted with multiple degrees of freedom, and the operation of visual field exposure in special steps of ophthalmic surgery is optimized to meet the requirements of visual field exposure in complex surgeries, such as the synchronous matching of the head tilt of glaucoma patients with the angle of the microscope during surgery. Combined with the flexibility of the thermal conductive silicone 402 on the surface of the headrest airbag 401, comfort is better ensured. In addition, the pressure distribution of the head contact surface is detected by the side pressure sensor 9. If the local pressure is greater than 30 mmHg, the side pressure sensor 9 is set to be connected to the signal of the side solenoid valve 602, which is conducive to timely exhausting the headrest airbag 401 through the side solenoid valve 602, thereby facilitating timely reducing the clamping force of the headrest airbag 401 on the patient's head, thereby better ensuring comfort.

[0031] In some embodiments, the surface of the headrest airbag 401 is connected to thermal conductive silicone 402, the inner surface of the concave head support 4 and the outer surface of the thermal conductive silicone 402 are coated with a nano-antibacterial coating 403, the side wall of the inner wall of the headrest airbag 401 is connected to several first thermal conductive plates 8 close to the thermal conductive silicone 402, the bottom of the concave head support 4 is connected to at least three second thermal conductive plates 12, and the inside of the headrest airbag 401 is connected to a temperature sensor 10 and a thermostat 11.

[0032] In this embodiment, by setting the first thermally conductive sheet 8 and the second thermally conductive sheet, the first thermally conductive sheet 8 and the second thermally conductive sheet are both set to be connected to the temperature sensor 10 and the thermostat 11 signal, and the temperature sensor 10 and the thermostat 11 are combined to control the temperature of the first thermally conductive sheet 8 and the second thermally conductive sheet 12, which is beneficial to adjust the perceived temperature of the patient's head within the adjustable range of 25-40°C, thereby ensuring the comfort of the concave head support 4 for the patient, and by setting the nano antibacterial coating 403, the cleanliness of the head is effectively guaranteed.

[0033] In some embodiments, the neck airbag 5 is provided at the bottom inner portion of the concave head support 4, and the second air pressure regulating component is provided below the concave head support 4 for adjusting the support height of the neck airbag 5 on the patient's neck. The second air pressure regulating component includes: a lower air pump 7, fixed to the lower end of the concave head support 4; a lower air supply pipe 701, connected to the air supply port of the lower air pump 7; a lower solenoid valve 702, connected to the end of the lower air supply pipe 701; a lower air inlet pipe 703, one end of which is connected to one side of the lower air supply pipe 701, and the other end of the lower air inlet pipe 703 is connected to the neck airbag 5.

[0034] In this embodiment, the patient's head and neck are flexibly supported by the neck airbag 5. When the lower air pump 7 is working, it is conducive to inflating the neck airbag 5 through the lower air supply pipe 701 and the lower air inlet pipe 703, which is conducive to increasing the support height of the neck airbag 5. If the support height is too high, the air in the neck airbag 5 is partially released through the lower solenoid valve 702 until the neck airbag 5 comfortably supports the patient's head and neck. In summary, due to the dynamic pressure compensation, the risk of cervical spine injury during surgery is reduced, the incidence of headache and neck pain after surgery is effectively reduced, cervical spine fatigue is effectively relieved, and the operation process is safer.

[0035] In some embodiments, the lifting plate 13 is slidably connected to the right side of the bed 1, and a screw motor 19 is fixed on the right side of the bed 1. The power end of the screw motor 19 is connected to a driving screw 1901, and the driving screw 1901 is threaded through the lifting plate 13. A fixed plate is fixed on the right side of the bed 1, and the end of the driving screw 1901 is rotatably connected to the fixed plate. The first stepper motor 1402, the second stepper motor 1601, the brake motor 1801, and the screw motor 19 are all connected to the angle sensor 17 signal.

[0036] In this embodiment, the screw motor 19 drives the screw 1901 to rotate forward and reverse, which is convenient for driving the lifting plate 13, the universal joint adjustment assembly and the concave head support 4 to move up and down, and is convenient for adjusting the support height of the concave head support 4 for the patient's head to ensure support comfort.

[0037] In some embodiments, a universal joint adjustment component is provided between the lifting plate 13 and the concave head support 4, and is used for universally adjusting the support angle and position of the concave head support 4 for the patient's head. The universal joint adjustment component includes: a first concave frame 14, which is provided above the lifting plate 13; a first rotating shaft 1401, one end of which is rotatably connected to the inner side of the first concave frame 14, and the other end of the first rotating shaft 1401 rotates through the outside of the first concave frame 14; a first stepper motor 1402, which is fixed to the outside of the first concave frame 14, and the other end of the first rotating shaft 1401 is connected to the power end of the first stepper motor 1402, and the universal joint adjustment component also includes: a second concave frame 15, which is provided in the first concave frame 14; a second rotating shaft 16, which rotates through the middle of the first rotating shaft 16, and the second rotating shaft 16 and the first rotating shaft 16 are distributed in a "cross" shape; a second stepper motor 1601 is fixed to the first rotating shaft 140 1 outer side; a main gear 1602, connected to the power end of the second stepping motor 1601; a sub-gear 1603, fixedly sleeved on the outer periphery of the second rotating shaft 16, the main gear 1602 and the sub-gear 1603 meshing, the universal joint adjustment assembly also includes: a support shaft 18, one end of which is rotatably connected to the upper end of the second concave frame 15, and the other end of the support shaft 18 is fixed to the lower end of the concave head support 4; a brake motor 1801, fixed to the upper end of the second concave frame 15; a driving gear 1802, connected to the power end of the brake motor 1801; a driven gear 1803, fixedly sleeved on the outer periphery of the support shaft 18, the driven gear 1803 meshing with the driving gear 1802; an angle sensor 17, fixed to the upper end of the lifting plate 13, the lower end of the first concave frame 14 is fixed to the sensing end of the angle sensor 17, a fixing frame 22 is fixed to the right side of the bracket 2, and a console 23 is fixed to the top of the fixing frame 22.

[0038] In this embodiment, when the patient's head is supported by the concave headrest 4, the angle sensor 17 performs angle sensing. If the support angle position is incorrect, the first stepper motor 1402 drives the first rotating shaft 1401 to rotate, the second stepper motor 1601 drives the main gear 1602, the sub-gear 1603 and the second rotating shaft 16 to rotate, and the brake motor 1801 drives the driving gear 1802, the driven gear 1803 and the support shaft 18 to rotate. Under the premise of setting the angle sensor 17 to be connected to the console 23 signal, the angle sensor 17 feeds back position data to the console 23 in real time. In summary, it is conducive to achieving three-axis adjustment of pitch, left and right yaw and lifting, thereby achieving the effect of multi-angle adjustment of the concave headrest 4, until the patient's head is comfortably supported by the concave headrest 4, and during the adjustment process, The rotational speeds of the first stepper motor 1402, the second stepper motor 1601, the brake motor 1801 and the screw motor 19 are all set at ≤5rpm, and the movement accuracy error is ≤0.5mm, which helps to avoid the patient from dizziness due to the adjustment process being too fast. In addition, the foot reset switch 24 is set to be electrically connected to the first stepper motor 1402, the second stepper motor 1601, the brake motor 1801 and the screw motor 19. By stepping on the foot reset switch 24, the first stepper motor 1402, the second stepper motor 1601, the brake motor 1801 and the screw motor 19 can be powered off in time, thereby preventing the first stepper motor 1402, the second stepper motor 1601, the brake motor 1801 and the screw motor 19 from causing excessive adjustment of the concave head support 4 due to work, thereby reducing safety hazards.

[0039] In some embodiments, two silicone hand support plates 20 are respectively provided on the front and rear sides of the bed body 1, and the front and rear sides of the bed body 1 are fixed with concave rails 2001, and the right wall of the concave rail 2001 is fixed with a forward and reverse motor 2002, and the power end of the forward and reverse motor 2002 is connected to a bidirectional screw rod 2003, and the end of the bidirectional screw rod 2003 is rotatably connected to the left wall of the concave rail 2001, and two lower guide blocks 2005 distributed on the left and right are slidably connected in the concave rail 2001. The guide blocks 2005 are all threadedly connected to the bidirectional screw rod 2003, and a telescopic frame 2004 is provided between the recessed rail 2001 and the silicone hand bracket plate 20. The two sides of the lower end of the telescopic frame 2004 are hinged to the lower guide block 2005 one by one, and the lower end of the silicone hand bracket plate 20 is fixed with a guide rod 2006.

The operator's elbow can fit the support surface to operate, thereby reducing fatigue. The operation of the forward and reverse motor 2002 drives the bidirectional screw 2003 to rotate. The bidirectional screw 2003 will drive the lower guide block 2005 to slide along the concave rail 2001. When the lower guide blocks 2005 approach each other, they will drive the telescopic frame 2004 to extend, and when the lower guide blocks 2005 move away from each other, they will drive the telescopic frame 2004 to contract. At the same time, the upper guide block 2007 will slide along the guide rod 2006, so that the height of the silicone hand support 20 when supporting the arm can be conveniently adjusted to better ensure the comfort of the patient's arm support.
