Description

Technical Field

[0001] The present invention relates to the technical field of eyelid retractors, and particularly to an adjustable eyelid retractor capable of stable support. Background Art

[0002] An eyelid retractor is an instrument used in ophthalmic surgeries to hold open the upper and lower eyelids in order to widen the surgical field of vision for doctors to perform operations. The working principle of an eyelid retractor is similar to that of a retractor in surgical operations. It forcibly holds open the eyelids through its tension. Most of its structures include two support arms and two eyelid hooks. The rear ends of the two support arms are integrated into a handheld part, and the front ends are two symmetrically arranged eyelid hooks. The eyelid hooks are generally set in a horizontally lying L-shaped structure. Its vertical part is inserted into the eye socket to fix the eyelid, and the horizontal part is used to limit the depth of the vertical part extending into the eye socket to prevent the vertical part from damaging the eyeball. It is an essential medical device in ophthalmic surgeries.

[0003] However, in actual use, we found that the existing eyelid retractors are all too large, which is not conducive to doctors' surgical operations. The shapes and sizes of some eyelid retractors are not reasonably designed, which may block the doctor's surgical field of vision, making it difficult for doctors to clearly observe the surgical site (such as an easy-to-disassemble eyelid retractor for ophthalmology disclosed in the invention patent with the publication number CN110200668A). This not only increases the difficulty and risk of the surgery but also may affect the surgical effect and the patient's postoperative recovery. Therefore, we propose an adjustable eyelid retractor capable of stable support. Summary of the Invention

[0004] One technical problem to be solved by the present application is: how to ensure that the eyelid retractor can provide sufficient surgical field of vision when medical staff use the eyelid retractor to operate on the patient's eyelids, so as to avoid affecting the operation of medical staff during the surgery and bringing unnecessary surgical risks.

[0005] To solve the above technical problem, the embodiment of the present application provides an adjustable eyelid retractor capable of stable support, which includes a partition for separating the eyeball and the eyelid, and there are two such partitions. It also includes

[0006] Two baffles, which are respectively arranged on the tops of the two partitions. The two baffles are used to push the patient's upper eyelid and lower eyelid respectively, so as to prevent the two partitions from separating from between the patient's eyelid and the eyeball.

[0007] Two arc-shaped grooves, which are respectively opened on the opposite sides of the two baffles. The two arc-shaped grooves are used to make the two baffles fit the opposite sides of the patient's upper eyelid and lower eyelid respectively.

[0008] The expansion component is arranged on one side of the two baffles. The two baffles are pushed by the expansion component to drive the upper eyelid and the lower eyelid of the patient respectively, so that the upper eyelid and the lower eyelid of the patient are separated.

[0009] In some embodiments, the expansion component includes screws respectively arranged at both ends of the two baffles. Among the four screws, two adjacent ones are in a group. Sleeves are arranged on the outer sides of the two groups of screws. Thread grooves are tapped in both sleeves, and the two sleeves are respectively threadedly connected to the two groups of screws through the two thread grooves. The rotation directions of the two ends of the thread grooves in the two sleeves are opposite.

[0010] In some embodiments, the expansion component includes support rods respectively arranged at both ends of the two baffles. Among the four support rods, two adjacent support rods are in a group. Compression springs are arranged on the opposite sides of each group of support rods. Round rods are slidably arranged on the outer sides of the two groups of support rods, and the two compression springs are respectively located in the adjacent round rods.

[0011] In some embodiments, the expansion component includes fixed rods respectively arranged at both ends of the two baffles, and the four fixed rods are respectively located at the tops of the two baffles. Fixed sleeves are rotatably arranged on the outer sides of the four fixed rods. Fixed torsion springs are arranged on both sides of the two baffles. The two ends of the two fixed torsion springs are respectively arranged on the outer sides of the adjacent fixed sleeves, and the two fixed torsion springs are both far away from the two baffles. The two ends of the two fixed torsion springs are both V-shaped.

[0012] In some embodiments, the expansion component includes a driving member arranged on one side of the two baffles to provide power for the expansion of the two baffles. An auxiliary member is arranged on one side of the two baffles to assist the expansion of the two baffles. A display member is arranged on one side of the two baffles to provide the force generated during the expansion of the two baffles for medical staff. A locking member is arranged on one side of the two baffles to lock the angle after the expansion of the two baffles.

[0013] In some embodiments, the driving member includes driving rods respectively arranged at one end of the two baffles. Among the two driving rods, a first driving plate is arranged on the outer side of one driving rod, and a second driving plate is arranged on the outer side of the other driving rod. A driving shaft is rotatably arranged at one end of the first driving plate and the second driving plate, and a driving torsion spring is movably arranged on the outer side of the driving shaft.

[0014] In some embodiments, the auxiliary component includes a first auxiliary plate arranged at the bottom of the first driving plate, a second auxiliary plate arranged at the bottom of the second driving plate, a first clip is arranged on the side of the first auxiliary plate close to the second driving plate, and a second clip is arranged on the side of the second auxiliary plate close to the first driving plate, and the two ends of the driving torsion spring are respectively arranged in the first clip and the second clip.

[0015] In some embodiments, the display component includes a display panel disposed on the second driving plate, and the display panel is arc-shaped, a plurality of scale grooves are opened on the display panel, a sliding groove is opened in the first driving plate, and the display panel is slidably set in the first driving plate through the sliding groove.

[0017] In some embodiments, the present invention provides an adjustable eyelid speculum that can be stably supported for use in medical devices for expanding the eyelids and providing a surgical field during ophthalmic surgery. In actual applications, after the upper eyelid and lower eyelid are spread open, two partitions can be respectively inserted between the upper eyelid and lower eyelid and the eyeball, and then the two sleeves are rotated at the same time. The threaded groove tapped in the sleeve will rotate with the sleeve, and the two ends of the threaded groove in the sleeve have opposite rotation directions, so that during the rotation of the sleeve, the two screws threadedly connected to it move synchronously in the opposite direction, and the two screws moving synchronously in the opposite direction will push the corresponding baffles, so that the distance between the two baffles becomes larger, and then the corresponding upper eyelid and lower eyelid are pushed respectively by the two baffles moving synchronously in the opposite direction. At the same time, there is no other structure blocking the line of sight, thereby providing a sufficient surgical field of view.

[0018] The present invention has at least the following beneficial effects:

[0019] By setting two partition plates, the eyeball and eyelid can be effectively separated, ensuring a clear field of view during the operation or examination. At the same time, the two baffles are respectively arranged at the top of the partition plates, which can push the upper eyelid and lower eyelid of the patient, ensuring that the partition plates are stably maintained between the eyelid and the eyeball and are not easily detached. The design of the arc-shaped groove enables the baffle to fit the opposite side of the patient's eyelid, increasing the comfort and stability of use. The threaded connection method of the screw rod and the sleeve not only has a simple structure but also is convenient to operate. The doctor only needs to rotate the sleeve to expand or contract the eyelid retractor, without complex operation steps or additional tools, improving the efficiency of the operation or examination, thus realizing the original intention of the design of this application and achieving the expected technical effect of the research and development.

Detailed implementation mode

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1:

[0034] Please refer to Figure 1 、 Figure 2 The present invention provides a technical solution:

[0035] An adjustable eyelid retractor that can stably support, includes a partition board 1 for separating the eyeball and the eyelid, and there are two partition boards 1. It also includes

[0036] Baffles 2, there are two, and the two baffles 2 are respectively arranged on the tops of the two partition boards 1. The two baffles 2 are used to push the patient's upper eyelid and lower eyelid respectively, so as to prevent the two partition boards 1 from separating from between the patient's eyelid and eyeball;

[0037] Arc grooves 3, there are two, and the two arc grooves 3 are respectively opened on the opposite sides of the two baffles 2. The two arc grooves 3 are used to drive the two baffles 2 to respectively fit the opposite sides of the patient's upper eyelid and lower eyelid;

[0038] Expansion component 4, arranged on one side of the two baffles 2. The expansion component 4 is used to push the two baffles 2 to move, so as to drive the two baffles 2 to push the patient's upper eyelid and lower eyelid respectively, and separate the patient's upper eyelid and lower eyelid.

[0039] The expansion assembly 4 includes screws 41 respectively arranged at both ends of the two baffles 2. Among the four screws 41, two adjacent screws form a group. Sleeves 42 are arranged on the outside of the two groups of screws 41. Thread grooves 43 are tapped in the two sleeves 42. The two sleeves 42 are threadedly connected to the two groups of screws 41 through the two thread grooves 43. The thread grooves 43 in the two sleeves 42 have opposite rotation directions at both ends.

[0040] When in use, when the medical staff needs to open the upper eyelid and the lower eyelid of the patient, the two partitions 1 are inserted between the upper eyelid and the lower eyelid and the eyeball respectively. The baffles 2 respectively arranged on the two partitions 1 can cover the upper eyelid and the lower eyelid of the patient after the partitions 1 are inserted between the upper eyelid and the lower eyelid and the eyeball of the patient, so as to prevent the patient's eyes from closing due to blinking or the normal operation of the muscles around the eyes, thereby affecting the medical staff's surgical operation. The arc groove 3 provided on the outer side of the baffle 2 can fit the curvature of the upper eyelid or the lower eyelid of the patient, so as to avoid damage to the eyelid caused by the eyelid opening process;

[0041] When the staff inserts the two partitions 1 between the patient's upper eyelid and lower eyelid and the eyeball respectively, and needs to expand the patient's upper eyelid and lower eyelid, the two sleeves 42 are rotated at the same time. When the two sleeves 42 are rotated at the same time, the threaded groove 43 tapped in the sleeve 42 will rotate along with the sleeve 42. Since the two ends of the threaded groove 43 in the sleeve 42 rotate in opposite directions, the two screws 41 threadedly connected to the sleeve 42 will move synchronously in the opposite direction during the rotation of the sleeve 42, and the two screws 41 moving synchronously in the opposite direction will push the corresponding baffles 2, so that the distance between the two baffles 2 becomes larger, and then the corresponding upper eyelid and lower eyelid are pushed respectively by the two baffles 2 moving synchronously in the opposite direction, which not only provides a sufficient surgical field for medical staff, but also prevents the baffle 2 or partition 1 from detaching from the eyelid due to blinking of the patient or contraction of the muscles around the corner of the eye.

[0042] Embodiment 2:

[0043] See also Figure 3 , Figure 4 Based on Example 1, the present invention provides another technical solution of the expansion component 4:

[0044] The expansion assembly 4 includes support rods 44 respectively arranged at both ends of the two baffles 2. Among the four support rods 44, two adjacent support rods 44 form a group. Each group of support rods 44 is provided with extrusion springs 45 on the opposite sides. Round rods 46 are slidably provided on the outer sides of the two groups of support rods 44, and the two extrusion springs 45 are respectively located in adjacent round rods 46.

[0045] When in use, when medical staff need to hold open the upper eyelid and lower eyelid of a patient, they pinch the two baffles 2 on the opposite sides, bringing the two baffles 2 closer. When the medical staff pinches the opposite sides of the two baffles 2, the support rods 44 respectively arranged at both ends of the two baffles 2 will move together and slide within the corresponding round rods 46, so that the compression springs 45 between each group of support rods 44 are compressed and start to contract. Then, the two partitions 1 are respectively inserted between the upper eyelid and lower eyelid of the patient and the eyeball. The baffles 2 respectively arranged on the two partitions 1 can block the upper eyelid and lower eyelid of the patient after the partitions 1 are inserted between the upper eyelid and lower eyelid of the patient and the eyeball, preventing the patient's eyes from closing due to blinking or the normal operation of the muscles around the eyes, thus affecting the surgical operation of the medical staff. The arc-shaped grooves 3 opened on the outer sides of the baffles 2 can fit the curvature of the upper eyelid or lower eyelid of the patient, avoiding damage to the eyelid caused during the process of holding the eyelid open;

[0046] After the staff inserts the two partitions 1 between the upper eyelid and lower eyelid of the patient and the eyeball respectively and needs to perform an expansion operation on the upper eyelid and lower eyelid of the patient, they release the two baffles 2. At this time, the compressed compression springs 45 start to exert force and push the corresponding two support rods 44 towards both ends. When the two support rods 44 receive the thrust of the compression springs 45, the two support rods 44 will push the two baffles 2 towards their opposite ends, causing the two baffles 2 to separate, and then pushing open the upper eyelid and lower eyelid of the patient through the two baffles 2, providing sufficient surgical fields for the medical staff. This embodiment has the effects of simple operation and fast expansion speed.

[0047] Embodiment 3:

[0048] Please refer to Figure 5 、 Figure 6 On the basis of Embodiment 1, the present invention provides another technical solution for the expansion assembly 4:

[0049] The expansion assembly 4 includes fixed rods 47 respectively arranged at both ends of the two baffles 2, and the four fixed rods 47 are respectively located at the tops of the two baffles 2. Fixed sleeves 48 are rotatably arranged on the outer sides of the four fixed rods 47. Fixed torsion springs are arranged on both sides of the two baffles 2. The two ends of the two fixed torsion springs are respectively arranged on the outer sides of the adjacent fixed sleeves 48, and the two fixed torsion springs are both far away from the two baffles 2. The two ends of the two fixed torsion springs are both in a V shape.

[0050] In use, when medical staff need to open the upper eyelid and lower eyelid of a patient, they pinch the two baffles 2 and move the two baffles 2 closer to their opposite sides. When the medical staff pinch the two baffles 2 and control them to move closer to their opposite sides, the fixing rods 47 respectively arranged at both ends of the two baffles 2 will move together with the two baffles 2, causing the two fixing rods 47 at both ends of the two baffles 2 to approach each other. When the fixing rod 47 moves, the fixing sleeve 48 rotatably arranged outside the fixing rod 47 will rotate on the fixing rod 47, and the fixing torsion spring 5 will start to be compressed and store energy. Then, the two partitions 1 are respectively inserted between the upper eyelid and lower eyelid of the patient and the eyeball. The baffles 2 respectively arranged on the two partitions 1 can block the upper eyelid and lower eyelid of the patient after the partitions 1 are inserted between the upper eyelid and lower eyelid of the patient and the eyeball, preventing the patient's eyes from closing due to blinking or the normal movement of the muscles around the eyes, thereby affecting the surgical operation of the medical staff. The arc-shaped groove 3 opened on the outside of the baffle 2 can fit the curvature of the upper eyelid or lower eyelid of the patient, avoiding damage to the eyelid caused during the process of opening the eyelid;

[0051] After the staff inserts the two partitions 1 between the upper eyelid and lower eyelid of the patient and the eyeball respectively and needs to perform an expansion operation on the upper eyelid and lower eyelid of the patient, the two baffles 2 are released. At this time, the charged fixing torsion spring starts to exert force and controls the fixing sleeves 48 at both ends to separate. When the two fixing sleeves 48 separate, the fixing sleeves 48 will drive the fixing rods 47 at their axles to separate, thereby expanding the upper eyelid and lower eyelid of the patient by the two baffles 2. The V-shaped of both ends of the fixing torsion spring can provide a wider surgical field for medical staff, facilitating the surgical operation of medical staff. This embodiment has the special V-shaped of the fixing torsion spring, which can bring the effect of a wider surgical field for medical staff.

[0052] Embodiment 4:

[0053] Please refer to Figures 7 - 11 , on the basis of Embodiment 1, the present invention provides another technical solution for the expansion component 4:

[0054] The expansion component 4 includes a driving member 49 arranged on one side of the two baffles 2, which provides power for the expansion of the two baffles 2. An auxiliary member 6 is arranged on one side of the two baffles 2 to assist in the expansion of the two baffles 2. A display member 7 is arranged on one side of the two baffles 2 to provide the force generated during the expansion of the two baffles 2 for medical staff. A locking member 8 is arranged on one side of the two baffles 2 to lock the angle after the expansion of the two baffles 2.

[0055] The driving member 49 includes driving rods 51 respectively arranged at one end of two baffles 2. Among the two driving rods 51, a first driving plate 52 is arranged outside one driving rod 51, and a second driving plate 53 is arranged outside the other driving rod 51. One end of the first driving plate 52 and the second driving plate 53 is rotatably provided with a driving shaft 54. A driving torsion spring 55 is movably arranged outside the driving shaft 54. When the extrusion on the first driving plate 52 and the second driving plate 53 is released, at this time, the first driving plate 52 and the second driving plate 53 will rotate under the action of the driving torsion spring 55, so that both the first driving plate 52 and the second driving plate 53 rotate outside the driving shaft 54. When the first driving plate 52 and the second driving plate 53 rotate, the driving rods 51 respectively arranged at one end of the first driving plate 52 and the second driving plate 53 will respectively follow the corresponding ends of the first driving plate 52 and the second driving plate 53 to rotate around the driving shaft 54 as the axis, so that the distance between the two driving rods 51 becomes larger. At this time, the two baffles 2 respectively arranged at the bottoms of the two driving rods 51 will follow the corresponding driving rods 51 to move, so that the distance between the two baffles 2 is enlarged, and then the upper eyelid and the lower eyelid of the patient are expanded by the two baffles 2. Its function is to provide the power for the expansion of the two baffles 2.

[0056] The auxiliary member 6 includes a first auxiliary plate 61 arranged at the bottom of the first driving plate 52. A second auxiliary plate 62 is arranged at the bottom of the second driving plate 53. A first buckle 63 is arranged on one side of the first auxiliary plate 61 close to the second driving plate 53. A second buckle 64 is arranged on one side of the second auxiliary plate 62 close to the first driving plate 52. Both ends of the driving torsion spring 55 are respectively arranged in the first buckle 63 and the second buckle 64. When the extrusion on the first driving plate 52 and the second driving plate 53 is released, at this time, the driving torsion spring 55 starts to exert force and respectively pushes the first auxiliary plate 61 and the second auxiliary plate 62 at both ends of it, so that the distance between the first auxiliary plate 61 and the second auxiliary plate 62 becomes larger. The first buckle 63 and the second buckle 64 respectively arranged on one side of the first auxiliary plate 61 and the second auxiliary plate 62 can replace the driving torsion spring 55 in time when the elastic force of the driving torsion spring 55 decreases. Its function is that when the elastic force of the driving torsion spring 55 is insufficient due to long-term use, the driving torsion spring 55 can be replaced in time, thereby saving costs.

[0057] The display member 7 includes a display panel 71 arranged on the second driving plate 53, and the display panel 71 is arc-shaped. A plurality of scale grooves 72 are provided on the display panel 71. A sliding groove 73 is provided in the first driving plate 52. The display panel 71 is slidably arranged in the first driving plate 52 through the sliding groove 73. When the first driving plate 52 and the second driving plate 53 rotate through the driving shaft 54, the display panel 71 arranged on one side of the second driving plate 53 will slide in the sliding groove 73 in the first driving plate 52. At this time, the medical staff can determine the stop position of the first driving plate 52 by observing the side of the first driving plate 52 close to the second driving plate 53, and observe the scale groove 72 on the display panel 71. Here, the scale groove 72 shows the force generated in the process of the driving torsion spring 55 exerting force. Its function is that the medical staff can determine the force applied by the two baffles 2 to the upper eyelid and the lower eyelid of the patient according to the scale groove 72, so as to avoid excessive force generated by the driving torsion spring 55, resulting in tearing or other problems around the patient's eyes.

[0058] The locking member 8 includes a plurality of locking grooves 81 provided on the display panel 71, the plurality of locking grooves 81 are connected in number and correspond one to one with the plurality of scale grooves 72, a guide groove 82 is provided in the first driving plate 52, a locking rod 83 used in cooperation with the plurality of locking grooves 81 is slidably provided in the guide groove 82, a locking handle 84 is provided on the top of the locking rod 83, a vertical plate 85 is provided in the sliding groove 73, a locking spring 86 is provided on one side of the vertical plate 85 close to the display panel 71, and the other end of the locking spring 86 is provided on one side of the locking rod 83, when the two baffles 2 separate the upper eyelid and the lower eyelid of the patient When there is a sufficient surgical field or the patient's eye corners are opened to the maximum, the locking handle 84 is released. At this time, the locking spring 86 begins to exert force, pushing the locking rod 83 to move in the guide groove 82, and the locking rod 83 slides to the end of the guide groove 82 and is inserted into the locking groove 81 of the display panel 71, thereby fixing the angle between the first drive plate 52 and the second drive plate 53, and fixing the distance between the two baffles 2. Its function is to fix the angle of the first drive plate 52 and the second drive plate 53 after rotation, ensuring that the expansion angle of the two baffles 2 is controlled.

[0059] When in use, in the initial state, the two baffles 2 are close to each other, and the first driving plate 52 is close to the second driving plate 53. When the medical staff needs to open the upper eyelid and the lower eyelid of the patient, the two baffles 1 are respectively inserted between the upper eyelid and the lower eyelid and the eyeball. The baffles 2 respectively arranged on the two baffles 1 can cover the upper eyelid and the lower eyelid of the patient after the baffles 1 are inserted between the upper eyelid and the lower eyelid and the eyeball, so as to prevent the patient's eyes from closing due to blinking or the normal operation of the muscles around the eyes, thereby affecting the surgical operation of the medical staff. The arc groove 3 provided on the outer side of the baffle 2 can fit the curvature of the upper eyelid or the lower eyelid of the patient, so as to avoid damage to the eyelid caused by the eyelid opening process.

[0060] When the staff members respectively insert the two partition plates 1 between the upper eyelid and the lower eyelid of the patient and the eyeball, and need to perform an expansion operation on the upper eyelid and the lower eyelid of the patient, push the locking handle 84, so that the locking handle 84 drives the locking rod 83 at its bottom to slide in the guiding groove 82, and makes the locking rod 83 disengage from the locking groove 81 on the display board 71 while approaching the vertical plate 85. When the locking rod 83 slides in the guiding groove 82 and approaches the vertical plate 85, the locking spring 86 starts to be compressed and store energy.

[0061] Then release the extrusion on the first driving plate 52 and the second driving plate 53. At this time, the driving torsion spring 55 starts to exert force, and respectively pushes the first auxiliary plate 61 and the second auxiliary plate 62 at its two ends, so that the distance between the first auxiliary plate 61 and the second auxiliary plate 62 becomes larger. The first buckle 63 and the second buckle 64 respectively arranged on one side of the first auxiliary plate 61 and the second auxiliary plate 62 can replace the driving torsion spring 55 in time when the elastic force of the driving torsion spring 55 decreases. When the first auxiliary plate 61 and the second auxiliary plate 62 move under the action of the driving torsion spring 55, the first driving plate 52 and the second driving plate 53 respectively arranged on the tops of the first auxiliary plate 61 and the second auxiliary plate 62 will move together with the corresponding first auxiliary plate 61 and the second auxiliary plate 62. At this time, the first driving plate 52 and the second driving plate 53 will rotate under the action of the driving torsion spring 55, so that the first driving plate 52 and the second driving plate 53 both rotate outside the driving shaft 54. When the first driving plate 52 and the second driving plate 53 rotate, the driving rods 51 respectively arranged at one ends of the first driving plate 52 and the second driving plate 53 will respectively follow the corresponding ends of the first driving plate 52 and the second driving plate 53 to rotate around the driving shaft 54 as the axis, so that the distance between the two driving rods 51 becomes larger. At this time, the two baffles 2 respectively arranged at the bottoms of the two driving rods 51 will follow the corresponding driving rods 51 to move, so that the distance between the two baffles 2 expands, and further expand the upper eyelid and the lower eyelid of the patient through the two baffles 2.

[0062] When the first driving plate 52 and the second driving plate 53 rotate through the driving shaft 54, the display panel 71 arranged on one side of the second driving plate 53 will slide in the sliding groove 73 in the first driving plate 52. At this time, the medical staff can determine the stop position by observing the side of the first driving plate 52 close to the second driving plate 53, and observe the scale groove 72 on the display panel 71. Here, the scale groove 72 shows the force generated during the force exertion of the driving torsion spring 55. When the two baffles 2 separate the upper eyelid and the lower eyelid of the patient to have a sufficient surgical field or reach the extreme opening of the patient's eye corners, the locking handle 84 is released. At this time, the locking spring 86 starts to exert force, pushing the locking rod 83 to move in the guide groove 82, and the locking rod 83 slides to the end of the guide groove 82 while being inserted into the locking groove 81 of the display panel 71, thereby fixing the angle between the first driving plate 52 and the second driving plate 53, and fixing the distance between the two baffles 2.
