Description
Technical Field
[0001] The present invention relates to the technical field of eyelid retractor force detection, and particularly to an ophthalmic eyelid retractor force detection device. Background Art
[0002] An eyelid retractor, also known as an eyelid speculum, is mainly used for supporting the expansion of a patient's eyelid area during ophthalmic surgery. In order to detect the true performance of the eyelid retractor after being pressed during actual use, a specific eyelid retractor force detection device is required for simulation measurement.

During this process, the eyelid hook will undergo relative deformation due to the contraction force of the eyelid skin. Once the quality of the eyelid retractor does not meet the standard, the contraction of the patient's eyelid area will cause excessive pressure on the support of the eyelid retractor and deformation, and in severe cases, there will be a risk of breakage of the eyelid retractor components.

[0016] By adopting the above technical solutions, the beneficial effects achieved by the present invention are as follows: 1. By detecting the external expansion and compressive performance of the adjustable eyelid retractor after production, when the eyelid hook is pressed and expands outward, the bending degree detection mechanism that actively bears on the outside of the eyelid hook can detect the two inner expansion force arms after opening in real time. As the inner expansion force arms expand outward, the movement states of the second spring and the slider can simulate the state of the patient's eyelid contraction, and at the same time, a reaction force will be applied to the inner expansion force arms. Once the inner expansion force arms do not meet the quality standard and are deformed under pressure, the pointer on the slider will directly show the distance it slides along the ranging scale, so that the deformation amount of the inner expansion force arms can be detected in real time.
[0017] 2. By arranging an eyelid hook pressure detection mechanism between the two bending degree detection mechanisms, when the inner expansion force arms are deformed under pressure and cause the eyelid hook to bend backward, the chuck attached to the inner side of the eyelid hook will apply an extrusion force to the machine base and the inclined frame. At this time, the two inclined frames will push the adapter upward, and finally the extrusion rod fixed in the adapter by the second bolt will apply a real-time pressure to the pressure detector, and the pressure detector can detect the reaction force of the eyelid hook in real time to simulate the damage pressure on the patient's eyelid part by the eyelid hook with a certain deformation amount during the operation.
[0018] 3. By arranging a stable lifting mechanism at one end of the suspension mechanism and an eyelid hook pressure detection mechanism at the other end of the suspension mechanism, the stable lifting mechanism can cooperate with the eyelid hook pressure detection mechanism to simulate the suspension platform after the produced eyelid retractor is horizontally placed as a whole, and the sliding seat assembly can cooperate with the two bending degree detection mechanisms to measure the micro-variables of the two eyelid hooks being reversely pressed after expansion in real time.

Detailed implementation manners
[0021] To make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention.
[0023] The following describes a force detection device for an ophthalmic eyelid retractor provided by some embodiments of the present invention in conjunction with the accompanying drawings.
[0024] Embodiment 1: Combined with Figures 1 to 9 As shown, a force detection device for an ophthalmic eyelid retractor provided by the present invention includes an eyelid retractor assembly 100, a suspension support assembly 300 disposed directly below the eyelid retractor assembly 100, a stable lifting mechanism 200 disposed at one end of the suspension support assembly 300, a eyelid hook pressure detection mechanism 400 disposed at the other end of the suspension support assembly 300, and two curvature detection mechanisms 500 disposed on the eyelid hook pressure detection mechanism 400. The stable lifting mechanism 200 is used to provide effective support for the horizontally placed eyelid retractor assembly 100 to simulate the real-time state of the eyelid retractor assembly 100 after being supported at the patient's eyelid part. The suspension support assembly 300 is used as a sliding platform to provide support for the stable lifting mechanism 200 and the eyelid hook pressure detection mechanism 400, facilitating the adaptability of the stable lifting mechanism 200 and the eyelid hook pressure detection mechanism 400 to the outwardly expanded eyelid retractor assembly 100 after movement. The eyelid hook pressure detection mechanism 400 is used to provide real-time detection of the reaction force after the deformation of the eyelid hook. The two curvature detection mechanisms 500 are used to provide real-time detection of the deformation amount of the components within the eyelid retractor assembly 100.
[0025] The eyelid retractor assembly 100 includes a first pressure-bearing pad 110 and a second pressure-bearing member 130, an adjustable distance screw rod 120 disposed inside the first pressure-bearing pad 110, two outward expansion force arms 160 movably installed at both ends of the first pressure-bearing pad 110, two inward expansion force arms 140 movably installed at both ends of the second pressure-bearing member 130, a pin 150 disposed inside the outward expansion force arm 160, and an eyelid hook 170 installed at the other end of the inward expansion force arm 140, and the pin 150 penetrates into the interior of the inward expansion force arm 140; The curvature detection mechanism 500 is used to provide a platform for detecting the deformation amount after the contraction of the two outwardly expanded inward expansion force arms 140 to simulate the actual patient's eyelid part; The curvature detection mechanism 500 includes a bottom plate 560 and a ranging scale 550 disposed outside the inward expansion force arm 140, an end plate 570 fixedly installed at the outer end of the bottom plate 560, a beam rod 5701 fixedly installed inside the end plate 570, a second spring 590 disposed outside the beam rod 5701, a slider 580 movably installed outside the beam rod 5701, an outer backing plate 530 fixedly installed at the inner ends of the ranging scale 550 and the bottom plate 560, a sliding column 540 fixedly installed at the other end of the outer backing plate 530, a second combination bolt 520 disposed inside the outer backing plate 530, and an inner backing plate 510 disposed outside the second combination bolt 520, and the inner backing plate 510 is adapted to fit closely to the inner side of the outer backing plate 530; One end of the top of the slider 580 is fixedly installed with a U-shaped pointer, and the inner side of the slider 580 is adapted to press against the outside of the inner expansion force arm 140.
[0026] When the second pressure-bearing member 130 is pushed by the distance-adjusting screw rod 120 and extends, the two inner expansion force arms 140 movably installed at both ends of the second pressure-bearing member 130 will drive the two eyelid-opening hooks 170 to expand outwards. After the two expanded eyelid-opening hooks 170 and the two inner expansion force arms 140, they can simulate the state of the patient's eyelid being externally supported. At this time, the inner side of the inner expansion force arm 140 will be limited and supported by the outer backing plate 530. The slider 580 is squeezed by the beam rod 5701 and the slider 580. This process simulates the contraction force of the patient's eyelid when the inner expansion force arm 140 expands outwards. Once the inner expansion force arm 140 is deformed due to excessive pressure, the pointer at the top of the slider 580 can move along the scale at the top of the distance measuring scale 550. By observing the real-time change of the pointer on the scale at the top of the distance measuring scale 550, the real-time deformation amount of the inner expansion force arm 140 with the gradually increasing opening angle can be detected, so as to effectively detect the pressure-bearing performance of the inner expansion force arm 140 during actual ophthalmic surgery.
[0027] Embodiment 2: Combined with Figures 1 to 4 As shown, on the basis of Embodiment 1, the suspension assembly 300 includes a bottom placing slide plate 320 arranged on the detection platform, a top placing slide plate 310 arranged on the top of the bottom placing slide plate 320, and two first combined bolts 330 installed at both ends of the stacked top placing slide plate 310 and the bottom placing slide plate 320. A chute 350 is opened inside one end of the top placing slide plate 310 close to the eyelid hook pressure detection mechanism 400, and two symmetrically distributed limiting card slots 340 are opened on both sides of the other end of the top placing slide plate 310. Both ends of the bottom placing slide plate 320 are provided with outwardly extending foot pads. The stable lifting mechanism 200 includes a sliding seat 210 movably installed outside the top placing slide plate 310, and two rectangular sliding pieces inside the sliding seat 210 are adaptively clamped in the two limiting card slots 340.
[0028] Preferably, the two foot pads at both ends of the top placing slide plate 310 are fixedly installed on the detection platform by bolts. When the threaded sections of the two first combined bolts 330 penetrate through the holes of the stacked top placing slide plate 310 and the bottom placing slide plate 320, and two nuts are installed on the two threaded sections, finally the two nuts can press the stacked top placing slide plate 310. At this time, the horizontally placed top placing slide plate 310 and the bottom placing slide plate 320 can provide a sufficiently stable sliding platform for the relative horizontal movement of the stable lifting mechanism 200 and the eyelid hook pressure detection mechanism 400.
[0029] The top of the sliding seat 210 is provided with a nut 220, a first bolt 230 arranged inside the nut 220, two cross bars 240 movably installed at both ends of the sliding seat 210, a first clamp 250 installed on one of the cross bars 240, a second clamp 260 installed on the other cross bar 240, and two limit ends 270 arranged on the two cross bars 240; Two first springs 280 are arranged outside both of the two cross bars 240; Cross plates are arranged on the inner sides of the first clamp 250 and the second clamp 260, and the first clamp 250 fits against the outer side of the first pressure-bearing pad 110, the second clamp 260 fits against the inner side of the first pressure-bearing pad 110, and the two cross plates are located at the bottom of the first pressure-bearing pad 110.
[0030] Preferably, the track structure formed by the bottom placing slide plate 320 and the top placing slide plate 310 after stacking can provide stable support for the sliding seat 210. At this time, the two rectangular sliding pieces inside the sliding seat 210 can be adaptively clamped to the two limit card slots 340. When the first clamp 250 and the second clamp 260 are adaptively attached to both ends of the first pressure-bearing pad 110, the first clamp 250 and the second clamp 260 that are relatively pressed by the two first springs 280 can quickly fix and clamp the first pressure-bearing pad 110. At this time, the overall eyelid retractor assembly 100 after being adjusted and expanded outward can be effectively supported by the first clamp 250 and the second clamp 260, and the horizontally placed and supported eyelid retractor assembly 100 can simulate the placement state during actual ophthalmic surgery.
[0031] Embodiment 3: Combined with Figures 5 to 9 As shown, on the basis of Embodiment 1, the eyelid hook pressure detection mechanism 400 includes a protective outer frame 430 movably installed outside the stacked top placing slide plate 310 and bottom placing slide plate 320, a third bolt 440 arranged inside the protective outer frame 430, a sliding seat assembly 410 arranged inside the protective outer frame 430, a pressure detector 420 arranged inside the sliding seat assembly 410, two mother tubes 450 installed inside the sliding seat assembly 410, two sub-rods 460 movably installed inside the two mother tubes 450, an inclined frame 470 movably installed between the sub-rods 460 and the sliding seat assembly 410, a base 480 movably installed at the bottom end of the inclined frame 470, and a chuck 490 arranged outside the base 480; The end face of the chuck 490 facing the eyelid hook 170 is provided with an inwardly concave V-shaped notch, and an anti-slip cushion layer is arranged on the inner wall of the V-shaped notch.
[0032] Preferably, the two chucks 490 are adapted and symmetric with the two eyelid retractors 170. When the outer expansion force arm 140 expands outward at too large an angle and is deformed under pressure, the eyelid retractor 170 fixed to the outer end of the outer expansion force arm 140 will apply a reverse extrusion force to the chuck 490. At this time, the chuck 490 will push the base 480 and the inclined frame 470 towards the center line of the sliding seat assembly 410. At this time, the two symmetrically distributed inclined frames 470 can be pressed to lift reversely.
[0033] The sliding seat assembly 410 includes a base 411 movably installed in the chute 350, a vertical rod 412 and a screw rod 413 installed in the base 411, a stability increasing member 414 arranged outside the vertical rod 412 and the screw rod 413 and directly above the base 411, a nut 418 installed on the threaded section of the screw rod 413, a swivel joint 415 movably connected to the adjacent ends of the two inclined frames 470, a second bolt 416 arranged in the swivel joint 415, and a pressing rod 417 installed inside the second bolt 416; The base 411 is integrally in a T-shaped structure, and a sleeve is arranged at the top of the base 411. The adjacent ends of the two mother pipes 450 are adapted to penetrate into the inside of the sleeve; A slideway is opened inside the inner backing plate 510. The outer end of the slide post 540 is adapted to penetrate into the slideway, and the inner backing plate 510 is installed on the chuck 490.
[0034] Preferably, after the adjacent ends of the two inclined frames 470 rise reversely, the swivel joint 415 movably installed at the adjacent ends of the two inclined frames 470 will lift upward. The pressing rod 417 fixed inside the swivel joint 415 by the second bolt 416 will apply an extrusion force to the pressure detector 420 after rising. At this time, the pressure detector 420 can detect the actual variable pressure of the chuck 490 in real time.
[0035] The working principle and usage process of the present invention: An eyelid opener, also known as an eyelid retractor, is similar to a retractor in a surgical operation. In terms of its own performance, an eyelid retractor is a retractor in an ophthalmic operation and is used to support the eyelids of a patient; Since the eyelid opener mainly expands the patient's eyelids outward, it is crucial to detect the stability of the eyelid opener after adjusting the patient's expanded eyelids; And this device provides detection for the reset performance of the eyelid hook of one type of adjustable sheet eyelid opener and the side bending of the connecting eyelid hook bracket; Previously, two sets of first combined bolts 330 are used to fixedly install the top slide plate 310 on the top of the top slide plate 310, and the bottom slide plate 320 is fixedly installed on the detection platform. The combined top slide plate 310 and bottom slide plate 320 are used to limit and clamp the slide seat 210. At this time, the two rectangular sliding pieces inside the slide seat 210 will respectively penetrate into the two limit card slots 340. According to the suspended position of the horizontally placed first pressure-bearing pad 110, then the slide seat 210 is adjusted to move horizontally along the top of the top slide plate 310 until the first fixture 250 and the second fixture 260 installed at both ends of the slide seat 210 through the two cross bars 240 adaptively clamp the inner and outer sides of the first pressure-bearing pad 110. At this time, the first pressure-bearing pad 110 can be limited and carried, so that the first bolt 230 can be tightened clockwise until its bottom end penetrates to the bottom of the nut 220 and presses on the top slide plate 310, and finally provide auxiliary support before detection for the horizontally placed eyelid opener assembly 100; Then, according to the positions of the two eyelid hooks 170 directly above the first pressure-bearing pad 110, the base 411 can be adjusted to move horizontally along the inside of the chute 350 until the two chucks 490 are respectively facing the two eyelid hooks 170. According to the detection requirements, by adjusting the rotation of the distance-adjusting screw rod 120, the second pressure-bearing member 130 is boosted to extend. At this time, the two inner expansion force arms 140 positioned and constrained by the two pin posts 150 will drive the two eyelid hooks 170 to expand outwards relatively. At this time, the rod body of the inner expansion force arm 140 will first apply an outward extrusion force to the slider 580. With the support of the beam rod 5701 for the slider 580, the outward-expanded inner expansion force arm 140 can maintain a constant pressure state to form an outward V-shaped structure. At the same time, the two chucks 490 can cooperate with the outward expansion of the two eyelid hooks 170 to adapt; Once the eyelid opener assembly 100 is deformed due to the material problems of the inner expansion force arm 140 and the eyelid hook 170 after outward expansion, the pointer at the top of the inner end of the slider 580 can move horizontally relative to the scale on the top of the distance measuring scale 550. At this time, the detection personnel can directly detect the deformation degree of the inner expansion force arm 140 under pressure; When the two inner expansion arms 140 are expanded outward to the maximum state and then deformed due to excessive pressure, the deformed inner expansion arms 140 and the eyelid-opening hooks 170 at their outer ends will move closer to the center line of the sliding seat assembly 410. At this time, the two chucks 490 will be subjected to reverse extrusion forces from the two eyelid-opening hooks 170. The base 480 and the inclined support 470 provided on the chuck 490 can then push the adapter 415 upward. The extrusion rod 417 fixed inside the adapter 415 by the second bolt 416 will then squeeze the pressure detector 420. At this time, the pressure detector 420 can measure the real-time extrusion force of the extrusion rod 417, so as to simulate the harm to the patient's eyelids caused by pressure problems during the actual use of this type of eyelid opener. At the same time, such a detection device can also detect the quality of the eyelid opener assembly 100 just after production, so as to avoid the harm caused by a poor-quality eyelid opener during the patient's eyelid-opening surgery.
