Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and particularly relates to a chassis control system for an ophthalmic operating bed. Background Art

[0002] As is well known, ophthalmology is a discipline that studies diseases occurring in the visual system, including the eyeball and related tissues. Generally, it studies various ophthalmic diseases such as vitreous body, retinal diseases, optometry, glaucoma and optic nerve diseases, and cataracts.

[0003] However, patients undergoing ophthalmic surgery generally suffer from serious diseases that affect their eye vision. During ophthalmic surgery, in order to ensure the smooth progress and success rate of the surgery, patients need to adopt a suitable position according to the surgical method, which is convenient for doctors to examine and operate on patients.

[0004] Currently, an ophthalmic operating bed includes a bed body support structure, a motion module that drives the support structure to lift and flip, a chassis structure, and a foot control structure. Among them, the chassis structure and the foot control structure form a chassis control system for controlling the lifting and flipping adjustment of the motion module. However, for the existing chassis control system, the following defects exist in actual use:

[0005] 1. When the lifting structure or the foot control structure fails, the existing chassis needs to be removed as a whole to troubleshoot the problem, which exposes the entire lifting structure, greatly increasing the risk of accidental damage by external forces. Moreover, each time of maintenance requires disassembling the entire chassis, and the operation is cumbersome;

[0006] 2. The position of the existing foot control structure is relatively fixed and is set close to the doctor's legs or feet. If the doctor's legs and feet are too close to the foot control structure, it is easy to have accidental touch problems. Moreover, the position of the foot control structure is difficult to meet the usage requirements of doctors of different heights. Doctors cannot operate in a comfortable foot position, which easily causes fatigue and soreness in the legs and feet, affecting the doctor's operation of the surgery. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved chassis control system for an ophthalmic operating bed.

[0008] To solve the above technical problems, the present invention adopts the following technical solutions:

[0009] An ophthalmic operating bed chassis control system, the ophthalmic operating bed includes a motion module, and the chassis control system includes:

[0010] A chassis structure, which includes a cover and a bottom shell forming a covering cavity;

[0011] A foot control structure, which is used to control the movement of the motion module,

[0012] The cover includes a plurality of cover bodies spliced together, wherein the tops and bottoms of the plurality of cover bodies are respectively aligned to form an open top and an open bottom. The motion module passes through the open top, and the bottom case is detachably connected to the open bottom.

[0013] The foot control structure includes a foot control component that is vertically movably arranged outside the cover or / and the bottom case. When the foot control component moves downward, it is in the open state, and when it moves upward, it is in the retracted state. The foot control structure also includes an adjustment component connected to the foot control component, and the adjustment component drives the foot control component to switch between the open state and the retracted state.

[0014] Preferably, each cover body includes an upper cover and a lower cover. A plurality of upper covers surround the outer periphery of the motion module, and a plurality of lower covers are connected to the bottom case to form a covering cavity. With this arrangement, the functional areas in the chassis are clearly divided, facilitating protection and maintenance.

[0015] Specifically, there are two cover bodies and they are symmetrically arranged. The two upper covers are correspondingly spliced to form an open top from the top, and the two lower covers are correspondingly spliced to form an open bottom from the bottom.

[0016] Furthermore, a first notch is formed at the splicing edge of each lower cover, and the upper cover extends upward from the edge corresponding to the first notch. When splicing, a channel extending in the vertical direction is formed between the two upper covers, and the motion module moves telescopically along the channel. With this arrangement, during telescopic movement, the channel can protect against foreign objects from getting stuck in the telescopic mechanism, ensuring the normal operation of components and improving safety at the same time.

[0017] Preferably, each lower cover includes a cover panel and a side plate. The cover panel is horizontally arranged above the bottom case, and one side edge of the cover panel is the splicing edge where the first notch is formed. The two lower covers are spliced from the splicing edge, and the side plate bends downward from the side of the cover panel away from the splicing edge. The covering cavity is formed among the cover panel, the side plate, and the bottom case. With this arrangement, the volume of the covering cavity can be increased, facilitating the layout of the foot control component and the motion module in the covering cavity.

[0018] Specifically, the cover panel extends from the middle towards both ends of the splicing edge and is inclined downward. The bottom edge of the cover panel and the bottom edge of the side plate are respectively connected to the top edge of the bottom case.

[0019] Furthermore, the cross-section of the cover panel is an arc that bends downward from the middle towards both ends of the splicing edge. With this arrangement, water accumulation on the surface of the chassis can be effectively avoided, preventing equipment damage caused by leakage.

[0020] Preferably, the cover panel includes a first panel and a second panel, wherein the first panel and the second panel are in a step-like shape that gradually rises from the splicing edge to the side panel. This arrangement facilitates the layout of the wheel assembly in the chassis and reduces the waste of other space in the chassis; at the same time, it forms a high and low staggered visual effect and enhances the aesthetics.

[0021] Preferably, the splicing edge is further formed with a second notch. When splicing, the second notches on the two cover panels are spliced ​​to form an operating opening that matches the operating end of the foot control component.

[0022] In addition, a plurality of positioning grooves are formed in the bottom shell, which respectively correspond to the foot control components and the motion modules.

[0023] Preferably, one side wall of the bottom shell is indented inwardly and formed with a guide groove, wherein the guide groove is vertically connected with the operation port, and the foot control component is movably connected in the guide groove. This arrangement ensures that the foot control component can move stably up and down.

[0024] According to a specific implementation and preferred aspect of the present invention, the foot control component includes a flip seat connected to the guide groove in an upside-down manner, and a foot control module arranged on the flip seat, wherein when the foot control component is in a retracted state, the outer surface of the flip seat is flush with the opening edge of the guide groove, and the foot control module is arranged to emerge upward from the operation port; when the foot control component is in an open state, the flip seat flips downward and emerges from the guide groove. In this way, when the foot control component is retracted, it can be stored in the guide groove, reducing the probability of accidental touch by external factors; at the same time, it can protect the foot control component.

[0025] Preferably, the flip seat includes a seat body pivotally connected in the guide groove and matched with the guide groove, a first flip arm and a second flip arm fixedly connected to opposite sides of the seat body from one end, and the adjustment component drives the first flip arm and the second flip arm to flip up and down synchronously, and the seat body flips up and down accordingly. This arrangement ensures that the flip seat flips up and down smoothly and avoids internal circuit misalignment.

[0026] Specifically, the first flip arm and the second flip arm are symmetrically arranged, wherein the flip seat further comprises a limit rod connected between the first flip arm and the second flip arm, a first through hole and a second through hole communicating with the cover cavity and the guide groove are arranged side by side on the side wall of the bottom shell, the first flip arm and the second flip arm pass through the first through hole and the second through hole respectively, the limit rod is located in the cover cavity, and when the foot control component is in the open state or / and the retracted state, the limit rod abuts against the corresponding side wall of the bottom shell. This arrangement prevents the foot control component from over-flipping and touching the ground.

[0027] Preferably, the adjusting member includes a first telescopic rod and a second telescopic rod disposed in the covering cavity. The first telescopic rod is pivotally connected to the end of the first turning arm extending into the covering cavity at one end; the second telescopic rod is pivotally connected to the end of the second turning arm extending into the covering cavity at one end. With this arrangement, the structure is simple. At the same time, the two telescopic rods are arranged in the inner cavity of the chassis to avoid exposure and improve the overall aesthetics.

[0028] Specifically, the motion module further includes a base disposed in the middle of the covering cavity. The first telescopic rod is pivotally connected to the base at the end away from the first turning arm. When the seat body is turned downward, the first telescopic rod extends; when the seat body is turned upward, the first telescopic rod contracts. With this arrangement, when the doctor opens the foot control member by hand, the first telescopic rod can assist in pushing the turning seat to turn, making the operation labor-saving. At the same time, when the foot control member is in the open state, the first telescopic rod extends and applies a top thrust to the first turning arm, which can form a lock to prevent shaking when the doctor adjusts the foot control module.

[0029] Furthermore, the second telescopic rod is pivotally connected to the inner wall of the bottom shell at the end away from the second turning arm, and the pivotal connection of the second telescopic rod on the inner wall of the bottom shell is located above the second turning arm. When the seat body is turned downward, the second telescopic rod contracts; when the seat body is turned upward, the second telescopic rod extends. With this arrangement, when the foot control member is retracted, the second telescopic rod can generate a large moment on the turning arm, making the operation labor-saving. At the same time, the foot control member can be locked in the retracted state to prevent accidental opening.

[0030] In addition, the foot control member further includes a switch communicated with the foot control module, and the triggering time of the switch is 3 to 5 seconds. With this arrangement, it effectively prevents accidental touch from starting the foot control module.

[0031] Specifically, the switch includes a switch body that is connected to the turning seat in a vertically flip - up and down manner and is disposed close to the foot control module, and an elastic member disposed between the switch body and the turning seat. Pressing the switch body downward starts the foot control module; releasing the switch body, the elastic member drives the switch body to flip upward and reset.

[0032] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0033] On the one hand, through the arrangement of multiple cover bodies of the present invention, opening the cover body corresponding to any part of the motion module can perform maintenance and repair operations, effectively improving the protection of other parts of the motion module, and the disassembly and assembly are simple and convenient. On the other hand, by opening and retracting the foot control member, it effectively avoids accidental touch, ensures the operation safety during surgery, and can meet the usage requirements of doctors of different heights, reducing the fatigue and soreness of the legs and feet caused by adjustment operations and improving the usage experience.

Detailed implementation manners

[0046] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe in detail the specific implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0047] As Figures 1 to 3 shown, the chassis control system of the ophthalmic operating bed in this embodiment includes a chassis structure I and a foot control structure II.

[0048] Specifically, the ophthalmic operating bed includes a motion module A1 and wheels A2.

[0049] In this example, the chassis structure I includes a bottom shell 1 and a cover 2. The cover 2 forms a top open mouth k1 at the top and a bottom open mouth k2 at the bottom. The bottom shell 1 is detachably connected to the bottom open mouth k2, and a covering cavity q is formed between the bottom shell 1 and the cover 2. The motion module A1 passes through the top open mouth k1 for telescopic movement; there are four wheels A2, which are respectively connected to the bottom shell 1, and the control module A20 of the wheels A2 is covered in the covering cavity q.

[0050] In this example, the bottom shell 1 is a shell with an open top and a downwardly convex bottom, and a plurality of positioning grooves c1 are formed at the bottom of the shell. The motion module A1 is inserted and fixedly connected to the corresponding positioning groove c1 through a base A10 located in the middle of the covering cavity q, and other electric control parts (such as an electric control box, etc.) are inserted and fixedly connected to the corresponding positioning groove c1.

[0051] At the same time, four connecting ears 10 are formed at intervals around the circumference of the top of the bottom shell 1, and the four wheels A2 are correspondingly connected to the four connecting ears 10.

[0052] For the convenience of implementation, an internal and external pull-out drawer 11 is also provided on one side of the bottom shell 1. Such a setting is convenient for storing sundries and convenient for use.

[0053] In this example, two cover bodies 20 are symmetrically arranged left and right. Each cover body 20 includes a lower cover 200 and an upper cover 201. The two upper covers 201 surround the outer periphery of the motion module A1, and the two lower covers 200 are respectively connected to the top opening edge of the bottom shell 1 and form a covering cavity q with the bottom shell 1. Such a setting makes the functional areas in the chassis clearly divided, which is convenient for protection and maintenance.

[0054] Specifically, the two upper covers 201 are correspondingly spliced and form an open top opening k1 from the top, and the two lower covers 200 are correspondingly spliced and form an open bottom opening k2 from the bottom.

[0055] Specifically, each lower cover 200 includes a cover panel a and a side panel b. The cover panel a is horizontally arranged above the bottom shell 1, and one side edge of the cover panel a is a splicing edge. The two lower covers 200 are spliced from the splicing edge. The side panel b is bent downward from the side of the cover panel a away from the splicing edge. A covering cavity q is formed between the cover panel a, the side panel b, and the bottom shell 1. This setting can increase the volume of the covering cavity and facilitate the layout of the control module and the motion module in the covering cavity.

[0056] Specifically, the cover panel a extends from the middle to both ends of the splicing edge and is inclined downward, and the bottom edge of the cover panel a and the bottom edge of the side panel b are respectively connected to the top edge of the bottom shell 1.

[0057] Furthermore, the cross-section of the cover panel a is an arc-shaped that bends downward from the middle to both ends of the splicing edge. This setting effectively avoids water accumulation on the surface area of the chassis and prevents equipment damage caused by leakage.

[0058] For the convenience of implementation, the cover panel a includes a first panel a1 and a second panel a2, and the first panel a1 and the second panel a2 are in a stepped shape that gradually rises from the splicing edge to the side panel b. This setting facilitates the layout of the wheel assembly in the chassis and reduces the waste of other spaces in the chassis; at the same time, it forms a visual effect of high and low levels, enhancing the aesthetic feeling.

[0059] In addition, the splicing edge of each first panel a1 is also formed with a first notch a11 and a second notch a12 that are spaced front and back. The upper cover 201 extends upward from the edge of the corresponding first notch a11. When the two cover bodies 20 are spliced, a channel t extending in the vertical direction is formed between the two upper covers 201, and the motion module A1 moves telescopically along the channel t; the two second notches a12 are spliced and form an operation opening k3.

[0060] As Figure 4 and Figure 5 shown, the foot control structure II includes a foot control component J1 and an adjustment component J2.

[0061] Combined with Figure 6 shown, a vertically penetrating guide groove c2 is recessed inward on one side wall of the bottom shell 1, and the guide groove c2 is vertically penetrated with the operation opening k3. The foot control component J1 is movably connected in the guide groove c2 and has an open state and a retracted state. This setting ensures the stable up and down movement of the foot control component.

[0062] In this example, the foot control component J1 includes a flipping base J10, a foot control module J11, and a switch J12. When the foot control component J1 is in the retracted state, the outer surface of the flipping base J10 is flush with the opening edge of the guiding groove c2, and the foot control module J11 protrudes upward from the operation port k3. When the foot control component J1 is in the open state, the flipping base J10 flips downward and protrudes from the guiding groove c2. With such a setting, when retracted, the foot control component can be accommodated in the guiding groove, reducing the probability of accidental touch by external factors. At the same time, it can protect the foot control component.

[0063] Specifically, the flipping base J10 includes a base body 100 that matches the guiding groove c2, a first flipping arm 101 and a second flipping arm 102 respectively fixedly connected to opposite sides of the base body 100 from one end. The adjusting component J2 drives the first flipping arm 101 and the second flipping arm 102 to flip up and down synchronously, and the base body 100 flips up and down accordingly. With such a setting, it ensures the smooth up and down flipping of the flipping base and avoids misalignment of the internal circuits.

[0064] Combined Figure 7 As shown, an inner cavity is formed inside the base body 100 and gradually narrows from top to bottom. The base body 100 is connected to the guiding groove c2 through a pivot s at the bottom and flips up and down around this pivot s. With such a setting, the base body can have a larger up and down flipping angle and a wide adjustment range.

[0065] For convenience of implementation, the first flipping arm 101 and the second flipping arm 102 are symmetrically arranged. A first through hole m1 and a second through hole m2 that communicate with the covering cavity q and the guiding groove c2 are arranged side by side on the side wall of the bottom shell 1. The first flipping arm 101 and the second flipping arm 102 correspondingly pass through the first through hole m1 and the second through hole m2 and extend into the covering cavity q.

[0066] Specifically, the flipping base J10 further includes a limiting rod 103 located in the inner cavity of the bottom shell 1. The limiting rod 103 is connected between the ends of the first flipping arm 101 and the second flipping arm 102 that extend into the covering cavity q. When the foot control component is in the open state, the limiting rod 103 abuts against the corresponding side wall of the bottom shell 1. With such a setting, it avoids the foot control component from over-flipping and touching the ground.

[0067] At the same time, a plurality of buffer pads d are arranged at intervals along the length direction of the limiting rod 103. With such a setting, each time the foot control component is opened, the impact force between the limiting rod and the chassis is reduced, improving the service life.

[0068] Specifically, the foot control module J11 is fixedly arranged on the top of the base body 100 and has two control rods (not shown in the figure but easy to imagine) respectively used for controlling the lifting and flipping movements of the ophthalmic operating bed.

[0069] Specifically, switch J12 is connected to the foot control module J11 and the triggering time is 3 to 5 seconds. The switch J12 includes a switch body 120 that is connected to the seat body 100 in an up-and-down flipping manner and is disposed close to the foot control module, and an elastic member 121 disposed between the switch body 120 and the seat body 100. Pressing the switch body 120 downward activates the foot control module J11; releasing the switch body 120, the elastic member 121 drives the switch body 120 to flip upward and reset.

[0070] Combined with Figure 8 As shown, a right-angled connecting groove c3 is formed on the seat body 100, and a connecting portion e passing through the connecting groove c3 is formed on the switch body 120, wherein the connecting portion e is pivotally connected to the inner cavity of the seat body 100.

[0071] In this example, the adjusting member J2 drives the foot control member J1 to switch between the open state and the retracted state. The adjusting member J2 includes a first telescopic rod 21 and a second telescopic rod 22 disposed in the covering cavity q. One end of the first telescopic rod 21 is pivotally connected to the end of the first flipping arm 101 extending into the covering cavity q; one end of the second telescopic rod 22 is pivotally connected to the end of the second flipping arm 102 extending into the covering cavity q. With such a setting, the structure is simple. At the same time, the two telescopic rods are disposed in the inner cavity of the chassis, avoiding exposure and improving the overall aesthetics.

[0072] Specifically, one end of the first telescopic rod 21 away from the first flipping arm 101 is pivotally connected to the base A10. When the seat body 100 flips downward, the first telescopic rod 21 elongates; when the seat body 100 flips upward, the first telescopic rod 21 contracts. With such a setting, when a doctor opens the foot control member by hand, the first telescopic rod can assist in pushing the flipping seat to flip, making the operation labor-saving; at the same time, when the foot control member is in the open state, the first telescopic rod elongates and applies a top thrust to the first flipping arm, capable of forming a lock to prevent shaking when the doctor adjusts the foot control module.

[0073] Furthermore, a connection module f is provided on the inner wall of the bottom case 1 above the second flipping arm 102. One end of the second telescopic rod 22 away from the second flipping arm 102 is pivotally connected to the connection module f. When the seat body 100 flips downward, the second telescopic rod 22 contracts; when the seat body 100 flips upward, the second telescopic rod 22 elongates. With such a setting, when retracting the foot control member, the second telescopic rod can generate a large moment on the flipping arm, making the operation labor-saving, and at the same time, the foot control member can be locked in the retracted state to prevent accidental opening.

[0074] It should be noted that the foot control structure II in this embodiment can use a circuit control system to control the automatic telescopic movement of the first telescopic rod 21 and the second telescopic rod 22 to automatically open and retract the foot control component J1; or the doctor can manually press to open or manually flick upward to retract the foot control component J1. At this time, the first telescopic rod 21 and the second telescopic rod 22 serve as auxiliary devices for the opening and retracting movement of the foot control component J1. The first telescopic rod 21 and the second telescopic rod 22 respectively apply a pushing force to the first flipping arm 101 and the second flipping arm 102, and maintain the upward flipping trend of the seat body 100 to achieve labor-saving operation and lock the foot control component J1 in the retracted state.

[0075] Therefore, this embodiment has the following advantages:

[0076] 1. Through the setting of multiple cover bodies, only the corresponding cover body needs to be opened each time for maintenance or repair operations on the corresponding part of the motion module, effectively improving the protection of the rest of the motion module and avoiding accidental damage; at the same time, the disassembly and assembly operations are simple and convenient;

[0077] 2. Effectively increase the volume of the covering cavity, facilitating the layout of the motion module in the covering cavity;

[0078] 3. Effectively avoid water accumulation on the surface area of the chassis and prevent equipment damage caused by leakage;

[0079] 4. Through the first panel and the second panel with different heights, it is convenient to layout the wheel assembly in the chassis, reducing the waste of other spaces in the chassis; at the same time, it forms a visual effect of high and low levels, enhancing the aesthetic feeling;

[0080] 5. By adjusting the component to open and retract the foot control component, it effectively avoids the doctor accidentally touching the foot control component and ensures the operation safety during the operation;

[0081] 6. By adjusting the foot control component up and down, it can meet the usage requirements of doctors of different heights. The adjustment operation is convenient, reducing the fatigue and soreness of the legs and feet and enhancing the usage experience;

[0082] 7. When the doctor opens the foot control component by hand, the first telescopic rod can assist in pushing the flipping seat to flip, making the operation labor-saving; at the same time, when the foot control component is in the open state, the first telescopic rod extends and applies a pushing force to the first flipping arm, which can form a lock to prevent shaking when the doctor adjusts the foot control module;

[0083] 8. When retracting the foot control component, the second telescopic rod can generate a large torque on the corresponding flipping arm, making the operation labor-saving, and at the same time can lock the foot control component in the retracted state to prevent accidental opening.

[0084] The above has described the present invention in detail, but the present invention is not limited to the above embodiments. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
