Description

Technical Field

[0001] The present invention relates to the technical field of ophthalmic medical instruments, and in particular to an ophthalmic operating table. Background Art

[0002] During ophthalmic surgery, although anesthesia prevents most patients from moving, some risks still exist during the operation. Since the eyes are a sensitive area of ​​the human body, once the patient moves, the operation may cause greater harm to the patient.

[0003] The prior art discloses (publication number: CN104644365B) an ophthalmic surgery auxiliary table, which includes a main body, a tool storage room on the front side of the main body, a storage baffle in the tool storage room, an anti-slip door frame on the outside of the tool storage room, a fan blade opening and closing control wheel mounting groove on the right side of the tool storage room, a fan blade opening and closing control wheel in the fan blade opening and closing control wheel mounting groove, a ventilation hole on the right side of the opening and closing control wheel mounting groove, and a shutter fan blade in the ventilation hole; it has complete functions and is easy to use. When medical staff treat patients with ophthalmic diseases, it saves time and effort, is scientific and convenient, safe and efficient, clean and hygienic, and reduces the difficulty of work for medical staff.

[0004] In order to prevent the patient from moving during surgery, the existing technology uses a fixation belt to fix the patient. However, the patient's head needs to be adjusted at an angle during ophthalmic surgery. When the patient's head rotates too much, the fixation belt fixes the patient's body, causing the patient's body to be unable to rotate with the head, resulting in compression of the nerves in the patient's neck. In severe cases, it may even lead to obstruction of blood circulation, affecting the normal progress of ophthalmic surgery. Therefore, we have proposed an ophthalmic operating table to solve the above problems. Summary of the Invention

[0005] The present invention is intended to provide an ophthalmic operating table to solve the problem that when the patient's head angle is adjusted, the patient's body is fixed, resulting in compression of the patient's neck nerves and, in severe cases, obstruction of blood circulation.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: an ophthalmic operating bed, comprising an operating bed, a headrest being provided at one end of the operating bed, a cavity being provided in the operating bed, a flip assembly being provided in the cavity, the flip assembly comprising a bed board, a driving member, a fixing member and two sets of supporting members, the bed board being provided in the cavity, and the lower end of the bed board passing through the operating bed, an installation cavity being provided in the bed board, a fixing member being provided between the installation cavity and the bed board, the fixing member being able to fix the patient, the driving member being provided at the lower end of the operating bed, the driving member being able to drive the bed board and the headrest to rotate, the supporting member comprising a supporting plate and a top plate, slide grooves being symmetrically provided in the bed board, the support plate being provided in the slide groove, through grooves being symmetrically provided on the bed board connected to the slide groove, the top plate being provided on the inner wall of the cavity, and the top plate passing through the through groove and abutting against the support plate.

[0007] The beneficial effects of this solution are as follows: by providing a flip assembly, the angle of the patient's body is adjusted to accommodate the rotation of the patient's head, thereby preventing the patient from suffering cervical nerve compression and blood circulation obstruction when the head rotates; the headrest is used to fix the patient's head to prevent the patient from moving during ophthalmic surgery; the driving member is used to drive the headrest and the bed board to rotate, thereby adjusting the angle of the head and body to meet the doctor's needs; the fixing member is used to fix the patient; when the patient lies flat on the bed board, the fixing member fixes the patient to prevent the patient from moving during the operation; the supporting member is used to support the patient; when the bed board is in an inclined state, due to the effect of gravity, the patient tends to slide down, and in this case, the supporting member cooperates with the patient's body to support the patient, thereby preventing the patient from moving during the operation and affecting the normal operation; the top plate is used to push the support plate to move, and the slide is used to install the support plate. When the bed board is flipped, the top plate does not move, but the bed board rotates relative to the top plate, so that the support plate located in the slide is pushed out by the top plate. The support plate pushed out of the bed board supports the patient, preventing the patient from moving during the angle adjustment process.

[0008] Preferably, as an improvement, the driving member includes a first rack, a second rack and a dual-rotor motor, the dual-rotor motor is arranged at the lower end of the operating bed, the first rack is arranged at the lower end of the headrest, the output end of the dual-rotor motor near the headrest is provided with a first gear meshed with the first rack, the second rack is arranged at one end of the bed board passing through the operating bed, and the output end of the dual-rotor motor near the bed board is provided with a second gear meshed with the second rack.

[0009] The beneficial effects are: the dual-rotor motor is used to ensure that the headrest and the bed board rotate synchronously, ensuring that the adjustment of the operating bed is more accurate and efficient, and the rotation of the headrest and the bed board is controlled by the transmission method of the first gear and the first rack, and the second gear and the second rack meshing, thereby improving the stability of the operating bed during adjustment, ensuring that the operating bed is stable and reliable during the adjustment process, and avoiding accidental movement.

[0010] Preferably, as an improvement, the fixing part includes an air pump and an air cushion, an installation cavity is opened in the bed board, the air pump is arranged in the installation cavity, a plurality of connecting pipes are provided between the bed board and the installation cavity, the air cushion is arranged at the upper end of the bed board, and a plurality of air intake valves connected to the connecting pipes are provided at one end of the air cushion close to the bed board, and the air pump inflates the air cushion through each connecting pipe and the air intake valve.

[0011] The beneficial effects are: an installation cavity is opened for installing an air pump, the air pump is used to inflate the air cushion, so that the air cushion expands to fix the patient's body, the connecting pipe is used to connect the air cushion and the air pump, so that the gas generated by the air pump is delivered to the air cushion, and the air inlet valve is used to control the inflow of gas so that the air cushion can be quickly inflated and reach the required pressure and support force, while also preventing gas leakage, ensuring that the air cushion can maintain a stable air pressure for a long time after inflation, and the air inlet valve is connected to the connecting pipe to fix the air cushion and prevent it from moving.

[0012] Preferably, as an improvement, it also includes two groups of positioning components, which are symmetrically arranged on the inner wall of the cavity. The positioning components include an adjustment plate, a magnetic strip, an iron bar and two mounting rods. The two mounting rods are symmetrically arranged on the inner wall of the cavity, the adjustment plate is arranged on the outer wall of the two mounting rods, the magnetic strip is arranged at the end of the adjustment plate away from the driving member, the upper ends of the two mounting rods are provided with limit blocks, the outer walls of each mounting rod are provided with a spring, and the spring is located between the adjustment plate and the cavity, the iron bar is provided at the lower end of the air cushion, and the magnetic strip can attract the corresponding iron bar.

[0013] The beneficial effects are: the positioning assembly is used to position the mattress, reducing the preoperative preparation time of medical staff. The iron bars are arranged on both sides of the mattress to facilitate medical staff to fold the mattress. At the same time, the iron bars on both sides can also assist medical staff to lay the uninflated mattress flat. When the bed board is in a horizontal state, the medical staff lays the mattress flat to the upper end of the bed board, and the iron bars are located on both sides of the bed board. At this time, the magnetic strips on the upper end of the adjustment plate are attracted to the corresponding iron strips, thereby limiting the two sides of the mattress to prevent the mattress from displacement. The spring is used to provide a floating distance for one end of the adjustment plate to avoid excessive suction between the magnetic strip and the iron strip to tear the mattress. The limit block is used to prevent the adjustment plate from sliding out of the guide range of the mounting rod, thereby improving the stability of the positioning assembly.

[0014] Preferably, as an improvement, it also includes a separation component, which is symmetrically arranged between the positioning component and the bed board, and the separation component includes a rotating rod, a rotating ring, a first contact plate and a second contact plate.

The second contact plate is provided on the outer wall of the bed board, and the second contact plate can contact the adjacent adjustment block.

[0015] The beneficial effects are: the separation component is used to separate the magnetic strips and the iron strips to avoid excessive attraction between the magnetic strips and the iron strips, and the iron strips at the lower end of the mattress are separated from the magnetic strips when the bed board rotates. To prevent the magnetic strips from pulling the iron strips excessively and causing damage to the mattress, when the bed board rotates, the second contact plate contacts the adjustment block, causing the swivel to rotate on the outer wall of the rotating rod, and the adjustment block on the other side of the swivel contacts the first contact plate, thereby causing the adjustment plate to move downward and separate from the iron strips, and because the bed board rotates, the iron strips move upward, and then quickly separate from the magnetic strips.

[0016] Preferably, as an improvement, a protective shell for housing the driving component is provided at the lower end of the operating bed.

[0017] The beneficial effect is that the protective shell is used to protect the normal operation of the driving component and prevent the driving component from being directly exposed to the external environment.

Figure 4 Several connecting pipes 17 are fixedly installed between the bed board 4 and the installation cavity 14 shown. The air cushion 16 is laid on the upper end of the bed board 4. The air cushion 16 includes a lying part 18 and two inflatable parts 19. The lying part 18 is arranged between the two inflatable parts 19. The lying part 18 is used for the patient to lie flat. The lying part 18 is composed of sponge and the inflatable part 19 is not connected to the lying part 18, and the lower end of each inflatable part 19 is connected and installed with several air intake valves fixedly connected to the connecting pipes 17. The air pump 15 inflates the air cushion 16 through each connecting pipe 17 and the air intake valve. When the patient lies flat on the lying part 18, relaxes his body and places his arms on both sides of the body. Then, the air pump 15 inflates the inflatable part 19, so that the inflatable part 19 expands toward the lying part 18, and the patient is fixed between the two inflatable parts 19.

[0029] It also includes two sets of positioning components, such as Figure 4 The two groups of positioning components are symmetrically arranged on the inner wall of the cavity 3. The positioning components include an adjustment plate 20, a magnetic strip 21, an iron bar 22 and two mounting rods 23. The two mounting rods 23 are symmetrically arranged on the inner wall of the cavity 3. The adjustment plate 20 is slidably installed on the outer walls of the two mounting rods 23.

The outer walls of each mounting rod 23 are sleeved with a spring 25, and one end of the spring 25 is fixedly connected to the lower end of the adjustment plate 20, and the other end is fixedly connected to the lower wall of the cavity 3. The iron bar 22 is fixedly installed at the lower end of the inflatable part 19, and the magnetic strip 21 is fixedly installed at the upper end of the adjustment plate 20, and the magnetic strip 21 can attract the corresponding iron bar 22.

[0030] Also includes separate components, such as Figure 4 The separation assembly shown is symmetrically positioned between the assembly and the bed board 4. The separation assembly includes a rotating rod 26, a rotating ring 27, a first contact plate 29 and a second contact plate 30. The rotating rod 26 is rotatably installed on the inner wall of the cavity 3, and the rotating ring 27 is fixedly installed on the outer wall of the rotating rod 26. The outer wall of the rotating ring 27 is symmetrically fixed with an adjustment block 28.

The second contact plate 30 is fixedly installed on the outer wall of the bed board 4, and the second contact plate 30 can contact the adjacent adjustment block 28.

[0031] like Figure 3A protective shell 31 for housing the driving component is fixedly mounted on the lower end of the operating bed 1 shown. The protective shell 31 is used to protect the normal operation of the driving component and prevent the driving component from being directly exposed to the external environment.

[0032] The specific implementation process is as follows:

[0033] When in use, the medical staff lays the air cushion 16 on the upper end of the bed board 4, and places the iron bars 22 on both sides of the inflatable part 19 on the left and right sides of the bed board 4. At this time, due to the large wrinkles of the inflatable part 19 and the lying part 18 of the mattress, the iron bars 22 at the lower end of the inflatable part 19 do not contact the corresponding magnetic strips 21. Then the medical staff fixes each air valve with the corresponding connecting pipe 17. When each air valve is connected to the connecting pipe 17, the medical staff starts the dual-rotor motor 5 to determine whether the bed board 4 can rotate normally. When the headrest 2 and the bed board 4 rotate to the left, the iron bar 22 on the left moves into the cavity 3, so that the iron bar 22 on the left first contacts the magnetic strip 21 on the left, and then positions the inflatable part 19 on the left side of the mattress. When the iron bar 22 on the left contacts the magnetic strip 21, the medical staff controls the headrest 2 and the bed board 4 to rotate to the right, so that the iron bar 22 on the right contacts the magnetic strip 21 on the right The medical staff can then make contact with the inflatable portion 19 on the right side of the mattress, and then level the headrest 2 and the mattress. At this time, the left and right inflatable portions 19 are straightened by the corresponding iron bars 22 and magnetic bars 21 respectively. During this process, the medical staff can not only detect the operating bed 1 to determine whether the operating bed 1 can be turned over, but also position and fix the inflatable portion 19 of the mattress to prevent the mattress from being displaced due to friction when the patient lies on the operating bed 1, resulting in the inability to effectively fix the patient when the inflatable portion 19 is subsequently inflated. After the patient lies flat on the lying portion 18 and puts his head into the headrest 2, the medical staff inflates each inflatable portion 19 through the air pump 15, so that the inflatable portions 19 on both sides of the patient are expanded, and the patient's arms and torso are fixed. Compared with the fixing belt fixation in the prior art, it can effectively prevent the patient from having blood circulation problems in the fixed position.

[0034] When the patient is fixed, if the bed board 4 needs to be tilted during the subsequent operation, the medical staff starts the dual-rotor motor 5 to tilt the headrest 2 and the bed board 4 in the required direction. In this embodiment, the headrest 2 and the bed board 4 tilt to the left, and in the process of the headrest 2 and the bed board 4 tilting to the left, the left support plate 10 slides out of the slide groove 12 and extends out of the bed board 4 under the action of the top plate 11, thereby positioning the edge of the inflatable part 19, thereby providing better support for the tilted patient, and while the support plate 10 is in contact with the inflatable part 19, it can also squeeze the inflatable part 19, thereby better wrapping the patient and preventing the patient from moving, and in the process of the bed board 4 rotating to the left, since the inflatable part 19 on the right rotates with a larger amplitude, the iron bar 22 at the lower end of the inflatable part 19 on the right contacts and attracts the magnetic strip 21. In order to prevent the inflatable part 19 from being pulled and causing unstable fixation of the patient, the separation component can more quickly separate the iron bar 22 on the right side from the corresponding magnetic strip 21. When the bed board 4 rotates to the left, the second contact plate 30 located on the outer wall of the bed board 4 abuts against the adjustment block 28, and as the bed board 4 continues to rotate, the second contact plate 30 pushes the rotating ring 27 to rotate, and the adjustment block 28 on the other side of the rotating ring 27 presses down the first contact plate 29, thereby moving the adjustment block 28 downward, prompting the iron bar 22 on the right side to separate from the magnetic strip 21, avoiding damage to the inflatable part 19 on the right side and affecting the fixation effect of the patient. In addition, during the rotation of the bed board 4, the first contact plate 29 and the second contact plate 30 on the right side always abut against the corresponding adjustment block 28, because the inflatable part 19 on the left side moves into the cavity 3.

[0035] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
