Description

Technical Field

[0001] The invention relates to the technical field of medical care, in particular to a device for sucking liquid from the conjunctival sac of an eyeball with an identification system. Background Art

[0002] There are many types of eye surgeries, including but not limited to cataract surgery, myopia correction surgery, glaucoma surgery, retinal surgery, and strabismus correction surgery. These are just common types of eye surgeries. In fact, the type of surgery will vary depending on the different eye diseases. With the continuous advancement of ophthalmic technology, new surgical methods are also constantly emerging.

[0003] During ophthalmic surgery, it is usually necessary to use an eyelid speculum to open the patient's palpebral fissure to ensure that the eyeball can be fully exposed for surgical operations. However, during the operation, the continuously exposed eyeball is prone to corneal dryness, which not only affects the progress of the operation, but may also cause corneal epithelial dysfunction after surgery. Therefore, balanced salt solution instillation is required to keep the eyeball moist during surgery. When the patient lies flat, due to the effect of gravity, the liquid may flow from the highest point of the cornea to the surroundings and accumulate in the conjunctival sac. Under normal circumstances, excess liquid can be naturally drained through the corners of the eyes. However, for the elderly, due to the small palpebral fissure, the liquid may not be able to drain smoothly, accumulate in the conjunctival sac, and may even submerge the highest point of the cornea, causing the surgical field to be covered by liquid, making it impossible for the operation to proceed smoothly.

[0004] For inexperienced doctors, any interference may affect their accurate judgment of the patient's condition; at the same time, during the highly concentrated operation, medical staff also need to monitor the changes in the amount of fluid in the conjunctival sac of the eye, which may interfere with the smooth progress of the operation. In addition, excessive fluid accumulation is usually difficult to effectively solve, and sometimes it is even necessary to cut the patient's outer canthus to promote fluid drainage, which will undoubtedly cause additional harm to the patient.

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0055] See also Figures 1 to 9 In an embodiment of the present invention, a device for sucking liquid from the conjunctival sac of the eye with an identification system comprises a fixed frame 1, and a sensing probe 11 arranged on the fixed frame 1;

[0056] The fixed frame 1 is provided with a connection structure; the sensing probe 11 is provided with a limit structure; the connection structure and the limit structure cooperate with each other to stably connect the sensing probe 11 to the fixed frame 1;

[0057] The fixed frame 1 is rotatably mounted with a rotating sleeve 22; a sliding sleeve 23 is slidably engaged with the rotating sleeve 22;

[0058] Mounting plates 14 are fixedly mounted on both sides of the fixed frame 1; a liquid suction mechanism is arranged on the mounting plate 14, and the liquid suction mechanism comprises a liquid suction sleeve 19 connected to the rotating sleeve 22; the liquid suction mechanism can suck the liquid in the conjunctival sac of the eyeball.

[0059] Taking an embodiment combining all the features described in the present application as an example, when in use, the patient wears the fixing frame 1 and fixes it with a strap to prevent the fixing frame 1 from shifting in the hand.

[0060] The sensing probe 11 is mounted on the fixed frame 1, and the connection structure and the limiting structure cooperate with each other so that the sensing probe 11 will not be easily separated from the fixed frame 1, thereby ensuring that during the operation, the sensing probe 11 can monitor the amount of liquid in the patient's conjunctival sac in real time so that the operation can proceed smoothly.

[0061] According to the specific condition of the patient, the position sensed by the sensing probe 11 is adjusted to enhance the applicability of the device and avoid the situation where the position to be monitored deviates from the sensing range of the sensing probe 11 due to different patient postures, thereby causing untimely or frequent aspiration.

[0062] A driving assembly capable of driving the rotating sleeve 22 to rotate is fixedly installed in the fixed frame 1 ; the driving assembly is controlled by the induction probe 11 .

[0063] During the operation, when the sensing probe 11 detects that the amount of liquid in the patient's conjunctival sac exceeds the set threshold, the sensing probe 11 will control the driving component to move, thereby driving the rotating sleeve 22 to rotate, thereby driving the sliding sleeve 23 to rotate toward the patient's eyes, and the sliding sleeve 23 will move closer to the conjunctival sac during the rotation process, thereby extending into the liquid in the conjunctival sac.

[0064] The liquid suction mechanism will be activated during the rotation of the rotating sleeve 22 to suck the liquid in the conjunctival sac of the patient's eye into the liquid suction sleeve 19 through the sliding sleeve 23 and the rotating sleeve 22. Thereby reducing the amount of liquid in the conjunctival sac of the patient's eye to ensure the smooth progress of the operation.

[0065] The amount of fluid in the conjunctival sac of the patient's eye can be monitored more accurately through the sensing probe 11, which is conducive to the medical staff to concentrate on the operation. In addition, the sensing angle of the sensing probe 11 can be adjusted according to the actual situation of the patient and the medical staff, which is conducive to the smooth progress of the operation.

[0066] In another embodiment of the present invention, the connection structure includes two groups of connection columns 2 fixedly mounted on the fixed frame 1 , and there is a gap between the two groups of connection columns 2 ; and a limit block 201 is fixedly mounted on the connection column 2 .

[0067] In another embodiment of the present invention, the limiting structure includes a connecting sleeve 3 disposed on the sensing probe 11 , and a limiting groove 301 cooperating with the limiting block 201 is formed on the connecting sleeve 3 .

[0068] Taking the embodiment of the combination of all the features recorded in this application as an example, when in use, the connecting sleeve 3 is inserted into the connecting column 2. Since the spacing between the limit blocks 201 is greater than the width of the inner wall of the connecting sleeve 3, the two limit blocks 201 will approach each other, thereby driving the connecting column 2 to deform and bend (the connecting column 2 has a certain elasticity), so that the connecting sleeve 3 can be smoothly inserted into the connecting column 2.

[0069] When the connecting column 2 is fully inserted into the connecting sleeve 3, the limit block 201 will reach the limit groove 301. At this time, the elastic force of the connecting column 2 will drive the connecting column 2 to reset, thereby driving the limit block 201 to enter the limit groove 301. Through the mutual cooperation between the limit block 201 and the limit groove 301, it is ensured that during the operation, the connecting sleeve 3 and the connecting column 2 will not be separated and are in a stably connected state, thereby ensuring that the sensing probe 11 can monitor the amount of liquid in the patient's conjunctival sac in real time during the operation.

[0070] After the operation is completed, an external force is applied to separate the limiting groove 301 of the limiting block 201 to release the stable connection state; and an external force is applied to pull the connecting sleeve 3 out of the connecting column 2 to facilitate the storage of the sensing probe 11.

[0071] In another embodiment of the present invention, a fixed sleeve 4 is fixedly installed on the connecting sleeve 3; a rotating rod 7 is rotatably installed in the fixed sleeve 4, and a mounting base 8 is fixedly installed on the rotating rod 7; a first hinge block 9 is fixedly installed on the mounting base 8; a second hinge block 10 is fixedly installed on the sensing probe 11, and the first hinge block 9 and the second hinge block 10 cooperate with each other and are both rotatably installed on a screw column 12, and an internally threaded sleeve 13 is threadedly connected to the screw column 12.

[0072] Taking the embodiment combining all the features recorded in the present application as an example, when in use, after the sensing probe 11 is stably connected to the fixed frame 1, the sensing probe 11 is rotated by applying external force to adjust the angle between the sensing probe 11 and the fixed frame 1, so as to adjust the sensing range of the sensing probe 11 (adjusted according to the specific condition of the patient). During this process, the first hinge block 9 and the second hinge block 10 will rotate relative to each other; after the adjustment is completed, the screw column 12 is rotated to make the screw column 12 and the internal threaded sleeve 13 threadably engaged, so as to drive the internal threaded sleeve 13 toward the first hinge block 9, thereby increasing the squeezing force between the first hinge block 9 and the second hinge block 10, so as to limit the continued relative rotation between the first hinge block 9 and the second hinge block 10, so as to ensure that the angle of the sensing probe 11 during the operation will not rotate easily, so as to prevent external factors such as collision from causing the sensing angle of the sensing probe 11 to change, so as to ensure that the sensing probe 11 accurately monitors the amount of liquid in the conjunctival sac of the patient's eye.

[0073] In another embodiment of the present invention, a baffle 401 is fixedly installed on the fixed sleeve 4; a slip ring 5 is slidably engaged on the fixed sleeve 4, a spring 6 is wrapped around the fixed sleeve 4, and both ends of the spring 6 are respectively in contact with the baffle 401 and the slip ring 5; a plurality of groups of first tooth blocks 501 are fixedly installed on the slip ring 5; and a plurality of groups of second tooth blocks 801 cooperating with the first tooth blocks 501 are fixedly installed on the mounting base 8.

[0074] Taking the embodiment combining all the features recorded in the present application as an example, when in use, in the initial state, the elastic force of the spring 6 will cause the first tooth block 501 and the second tooth block 801 to engage with each other, so that the rotating rod 7 cannot be easily rotated, thereby ensuring that the sensing probe 11 will not easily turn during the operation, so as to ensure accurate monitoring of the amount of liquid in the patient's conjunctival sac.

[0075] When it is necessary to adjust the sensing angle of the sensing probe 11 or switch the surgical site according to the patient's body shape, an external force is applied to make the slip ring 5 slide in the direction of the baffle 401 to compress the spring 6, so that the first tooth block 501 and the second tooth block 801 are separated from each other to release the rotation restriction of the rotating rod 7; at this time, the mounting base 8 can be rotated to adjust the sensing range of the sensing probe 11.

[0076] After the adjustment is completed, the external force applied to the slip ring 5 is removed; at this time, the elastic force of the spring 6 will drive the slip ring 5 to move closer to the direction away from the baffle 401, so as to drive the first tooth block 501 and the second tooth block 801 to contact and engage with each other, thereby limiting the adjusted sensing probe 11 to ensure accurate monitoring of the amount of liquid in the patient's conjunctival sac.

[0077] In another embodiment of the present invention, the liquid suction mechanism also includes a motor 15 fixedly mounted on the mounting plate 14; a driving sleeve 16 is fixedly mounted on the output end of the motor 15; a matching groove is provided in the driving sleeve 16; the liquid suction sleeve 19 is fixedly mounted on the mounting plate 14; a piston 18 is slidably engaged in the liquid suction sleeve 19; a guide rod 17 is fixedly mounted on the piston 18; a raised column 1701 slidably engaged with the matching groove is fixedly mounted on the guide rod 17; a sliding disk 1702 is fixedly mounted on the guide rod 17; a sliding groove 1703 is provided on the sliding disk 1702; a raised column 1901 slidably engaged with the sliding groove 1703 is fixedly mounted in the liquid suction sleeve 19.

[0078] Taking the embodiment combining all the features recorded in the present application as an example, when in use, when the motor 15 is in operation, it will drive the driving sleeve 16 to rotate, thereby driving the matching groove to rotate synchronously, so that the protruding column 1701 will slide with the matching groove, thereby driving the guide rod 17 to slide back and forth in the liquid suction sleeve 19; during this process, the protruding column 1901 will slide with the sliding groove 1703.

[0079] The reciprocating guide rod 17 drives the piston 18 to slide reciprocally in the liquid suction sleeve 19, so that the liquid in the conjunctival sac of the patient's eye can be sucked into the liquid suction sleeve 19 through the sliding sleeve 23 and the rotating sleeve 22, thereby ensuring the smooth progress of the operation.

[0080] And through the mutual interference and cooperation between the protruding column 1901 and the sliding groove 1703, the sliding plate 1702 can only slide in the liquid suction sleeve 19 and cannot rotate, thereby ensuring that the guide rod 17 will not rotate, so that the protruding column 1701 can smoothly slide and cooperate with the matching groove; and it can prevent the piston 18 from rotating to ensure the smooth progress of the liquid suction process, and at the same time can reduce the loss of the piston 18 to increase the service life of the device.

[0081] In another embodiment of the present invention, the mating groove includes a first oblique groove 1601, a first flat groove 1602, a second oblique groove 1603 and a second flat groove 1604; one end of the first oblique groove 1601 is connected to one end of the first flat groove 1602, the other end of the first flat groove 1602 is connected to one end of the second oblique groove 1603, the other end of the second oblique groove 1603 is connected to one end of the second flat groove 1604, and the other end of the second flat groove 1604 is connected to the other end of the first oblique groove 1601.

[0082] Taking the embodiment combining all the features described in the present application as an example, when in use, when the raised column 1701 slides in the first inclined groove 1601 toward the first flat groove 1602, the inner wall of the first inclined groove 1601 will squeeze the raised column 1701 to drive the guide rod 17 toward the motor 15, thereby driving the piston 18 to slide synchronously, and the sliding sleeve 23 can absorb the liquid in the conjunctival sac of the patient's eye.

[0083] When the protruding column 1701 slides in the first flat groove 1602 toward the second inclined groove 1603, the position of the guide rod 17 remains unchanged, so the position of the piston 18 remains unchanged.

[0084] When the protruding column 1701 slides in the second inclined groove 1603 toward the second flat groove 1604, the inner wall of the second inclined groove 1603 will squeeze the protruding column 1701 to drive the guide rod 17 to move away from the motor 15, thereby driving the piston 18 to move synchronously, and the exhaust action is performed at this time.

[0085] When the protruding column 1701 slides in the second flat groove 1604 toward the first inclined groove 1601, the position of the guide rod 17 remains unchanged.

[0086] When the matching groove and the raised column 1701 are matched, the suction mechanism will perform suction and exhaust actions, and there is an interval between the suction and exhaust actions (i.e. suction, stillness, exhaust, stillness), which can quickly extract the liquid in the conjunctival sac of the patient's eye and increase the service life of the device.

[0087] In another embodiment of the present invention, a liquid suction joint 1902 and an exhaust joint 1903 are fixedly installed on the liquid suction sleeve 19, and the liquid suction joint 1902 is connected to the rotating sleeve 22 through a conduit 21; the liquid suction sleeve 19 is also threadedly connected to a liquid storage tank 20.

[0088] Taking the embodiment combining all the features recorded in the present application as an example, when in use, a one-way valve is provided between the liquid suction connector 1902 and the exhaust connector 1903; that is, when the liquid suction action is performed, the liquid suction connector 1902 is connected, and the exhaust connector 1903 is closed; and when the exhaust action is performed, the liquid suction connector 1902 is closed, and the exhaust connector 1903 is connected; and the liquid sucked into the liquid suction sleeve 19 will flow into the liquid storage tank 20 for subsequent inspection and to prevent the liquid from contaminating the operating room.

[0089] By alternately connecting the liquid suction connector 1902 and the exhaust connector 1903, the liquid suction speed can be effectively increased, and blowing air into the conjunctival sac of the patient's eye, which increases the difficulty of the operation, can be avoided.

[0090] In another embodiment of the present invention, a telescopic slot 101 is provided on the fixed frame 1; a sliding block 2301 slidably engaged with the telescopic slot 101 is fixedly mounted on the sliding sleeve 23; and the telescopic slot 101 is inclined.

[0091] Taking the embodiment combining all the features recorded in the present application as an example, when in use, when the sensing probe 11 senses that the amount of liquid in the conjunctival sac of the patient's eye exceeds the set threshold, the rotating sleeve 22 will be controlled to drive the sliding sleeve 23 to rotate toward the patient's eye; during the rotation process, the slider 2301 will slide in the telescopic groove 101, thereby driving the sliding sleeve 23 to slide synchronously on the rotating sleeve 22, thereby reducing the distance between the sliding sleeve 23 and the patient's eye, thereby facilitating the extraction of liquid in the conjunctival sac of the eye.

[0092] When the amount of liquid in the patient's conjunctival sac is less than the set threshold after being absorbed by the aspiration mechanism, the sensing probe 11 will control the rotating sleeve 22 to drive the sliding sleeve 23 to rotate away from the patient's eyes. At this time, the slider 2301 will drive the sliding sleeve 23 to slide in the opposite direction on the rotating sleeve 22 to avoid the excessive length of the rotating sleeve 22 and the sliding sleeve 23 affecting the smooth progress of the operation, thereby effectively improving the success rate of the operation.

[0093] In another embodiment of the present invention, the sliding sleeve 23 is made of soft rubber material, and the end thereof is relatively smooth.

[0094] Taking the embodiment combining all the features described in the present application as an example, when in use, the soft rubber material and the smooth port can effectively prevent the sliding sleeve 23 from causing damage to the patient's eyes when approaching the eyes.

[0095] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
