TECHNICAL FIELD

[0001] The present application belongs to the technical field of sterilization and cleaning, and particularly relates to a sterilization and cleaning device for a capsulorhexis forceps used in cataract treatment surgery. BACKGROUND

[0002] The capsulorhexis forceps is a special micro-instrument used in ophthalmic cataract surgery, with a small tip and internal fine teeth or platform, which can firmly hold the thin and tough capsule membrane to prevent slipping. The forceps arm usually has a certain angle, which can allow the doctor to operate through a small corneal incision, avoiding the hand and instrument handle from the eyeball and microscope, and obtaining the best operation view and angle while keeping comfortable. Since the capsulorhexis forceps is expensive, the tip is extremely delicate (easy to break), and directly contacts the intraocular tissue, it needs to be cleaned and disinfected before and after use to remove contaminants and prevent postoperative infection.

[0003] After use, the capsulorhexis forceps is easily contaminated with bloodstains or other impurities. In order to facilitate subsequent reuse, the capsulorhexis forceps needs to be cleaned and disinfected. The capsulorhexis forceps is placed in a cleaning and disinfecting device for soaking, brushing and other steps. However, in actual use, the capsulorhexis forceps needs to be transferred out of the cleaning and disinfecting device after cleaning, which can easily cause recontamination during the transfer process. In addition, when cleaning a large number of capsulorhexis forceps, the capsulorhexis forceps are easily stacked, which can cause blind spots in cleaning and disinfection, and the stacked capsulorhexis forceps can be easily damaged during cleaning and disinfection.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] For a specific implementation example, please refer to Implementation Example 1. Figures 1-12 The present invention is a sterilization and cleaning device for capsulorhexis forceps in cataract treatment surgery, including a cleaning control component 1. Specifically, the cleaning control component 1 includes a cleaning inner frame 101 that can move up and down and horizontally. Two forceps limiting components 2 are symmetrically slidably arranged inside the cleaning inner frame 101. A horizontal adjustment component 3 is fixedly connected inside the cleaning inner frame 101. The horizontal adjustment component 3 is fixedly connected to the two forceps limiting components 2. An opening and closing control component 4 is fixedly connected to one side of the cleaning control component 1. The cleaning and control component 1 is used to clean and disinfect the capsulorhexis forceps, making it convenient to transfer the cleaned capsulorhexis forceps. At the same time, it can control the opening and closing state of the opening and closing control component 4. The forceps limiting component 2 is used to limit the position of forceps of different sizes to prevent forceps from stacking together; The horizontal adjustment component 3 is used to drive the two tweezers limiting components 2 to move horizontally, thereby increasing the cleaning effect; The opening and closing control component 4 is used to control the entry and exit of the cleaning and disinfection solution inside the cleaning control component 1.

[0033] The operation process of this embodiment is as follows: The tweezers to be cleaned are placed inside the tweezers limiting component 2 with the handle facing down and the clamping end facing up. The tweezers limiting component 2 limits the position of the tweezers and reduces the contact area between the tweezers limiting component 2 and the tweezers during the limiting process. The tweezers are cleaned and disinfected using the cleaning control component 1. During the cleaning and disinfection process, the horizontal adjustment component 3 drives the tweezers limiting component 2 to move horizontally in sync, and impurities and contaminants fall into the cleaning control component 1. After the tweezers are cleaned and disinfected, the inner cleaning frame 101 moves up a certain height and then rotates a certain angle, thereby driving the cleaned and disinfected tweezers to move synchronously for transfer. The tweezers limiting component 2 releases its restriction on the tweezers, and the cleaned and disinfected tweezers are then taken out. During the upward movement of the inner cleaning frame 101, the opening and closing control component 4 opens, and the wastewater from the cleaning control component 1 is discharged to facilitate the next cleaning and disinfection operation.

[0034] For a specific embodiment two, please refer to Figures 1-12Based on the specific embodiment 1, the cleaning control component 1 further includes a fixedly installed cleaning support frame 102. An ultrasonic cleaning device is fixedly installed inside the cleaning support frame 102. During the cleaning and disinfection process, the capsule tearing forceps are cleaned and disinfected with a cleaning and disinfection solution. A liquid outlet is opened on one side of the cleaning support frame 102. The cleaning inner frame 101 is slidably installed inside the cleaning support frame 102. The cleaning inner frame 101 has a hollow frame structure, which facilitates the falling of impurities and contaminants into the cleaning support frame 102 during the cleaning process. A transfer bracket 103 is fixedly installed on the upper surface of the cleaning inner frame 101. A transfer transmission ring 104 is fixedly connected to one end of the transfer bracket 103. A transmission rack 105 is fixedly connected to one side of the transfer bracket 103 through an L-shaped support frame.

[0035] Furthermore, a hollow support column 106 is fixedly connected to the other side of the cleaning support frame 102 via an extension support plate. The transfer transmission ring 104 is slidably disposed on the periphery of the hollow support column 106, and a transfer control slide 107 is provided on the periphery of the hollow support column 106. The transfer control slide 107 is composed of a horizontal slide and a vertical slide that are interconnected. A transmission internal thread tube 108 is coaxially disposed inside the hollow support column 106. An arc-shaped transmission block 109 is fixedly connected to the periphery of the transmission internal thread tube 108. The arc-shaped transmission block 109 slides with the transfer control slide 107, and the arc-shaped transmission block 109 is fixedly connected to the transfer transmission ring 104.

[0036] A drive screw 110 is rotatably connected coaxially inside the hollow support column 106. The drive screw 110 is threadedly engaged with the transmission internal thread tube 108. A transmission bevel gear 111 is rotatably mounted on the lower surface of the hollow support column 106. The transmission bevel gear 111 is fixedly connected to the drive screw 110. A support plate is fixedly mounted on one side of the cleaning support frame 102. A drive bevel gear 112 is rotatably connected to one side of the support plate. The drive bevel gear 112 meshes with the transmission bevel gear 111. A drive motor is fixedly mounted on the other side of the support plate. The output shaft of the drive motor is fixedly connected to the drive bevel gear 112.

[0037] Furthermore, the opening and closing control assembly 4 includes a liquid outlet pipe fixedly connected to the side of the cleaning support frame 102 near the liquid outlet and coaxial with the liquid outlet. A liquid outlet ring 401 is fixedly connected to one side of the liquid outlet pipe. A plurality of guide grooves 402 are provided on one side of the liquid outlet ring 401. A liquid outlet control frame 403 is rotatably arranged on one side of the liquid outlet ring 401. A transmission external gear ring 404 meshing with a transmission rack 105 is fixedly connected to the periphery of the liquid outlet control frame 403. An inclined groove 405 corresponding to the guide grooves 402 is provided on the inner side wall of the liquid outlet control frame 403. An opening and closing plate 406 corresponding to the guide slide 402 is provided between the liquid outlet ring 401 and the liquid outlet ring 401. When the opening and closing plates 406 are in contact with each other, they form a sealed structure, so that the liquid outlet ring 401 remains sealed and the discharge of cleaning and disinfection solution is controlled. A transmission strip that slides and engages with the corresponding guide slide 402 is fixedly connected to one side of the opening and closing plate 406. An opening and closing column that slides and engages with the corresponding inclined slide 405 is fixedly connected to the other side of the opening and closing plate 406. A connecting pipe 407 is rotatably provided on one side of the liquid outlet control frame 403. The connecting pipe 407 is fixedly connected to the cleaning support frame 102 through a connecting bracket.

[0038] The operation process of this embodiment is as follows: After cleaning and disinfection, the drive motor is started to drive the drive bevel gear 112 to rotate. Under the meshing action of the drive bevel gear 112 and the transmission bevel gear 111, the transmission bevel gear 111 rotates synchronously, thereby driving the drive screw 110 to rotate. Under the threaded engagement of the drive screw 110 and the transmission internal thread tube 108, and the sliding engagement of the arc-shaped transmission block 109 and the transfer control slide 107, the transmission internal thread tube 108 gradually moves upward, the arc-shaped transmission block 109 moves upward along the vertical slide of the transfer control slide 107, and the transfer transmission ring 104 moves upward synchronously along the circumferential side of the hollow support column 106. Under the connection of the transfer bracket 103, the inner cleaning frame 101 moves upward. When the arc-shaped transmission block 109 moves to the intersection of the vertical slide and the horizontal slide, the inner cleaning frame 101 moves away from the cleaning support frame 102. The arc-shaped transmission block 109 is no longer restricted, and the drive screw 110 rotates, causing the transmission internal thread tube 108 to rotate synchronously. The arc-shaped transmission block 109 slides along the inside of the horizontal slide, and the transfer transmission ring 104 rotates along the circumferential side of the hollow support column 106. Under the connection of the transfer bracket 103, the inner cleaning frame 101 rotates at a certain angle and deviates from the cleaning support frame 102, making it convenient to transfer the cleaned and disinfected capsule tearing forceps.

[0039] During the upward movement of the transfer bracket 103, the transmission rack 105 moves upward synchronously under the connection of the L support frame. Under the meshing action of the transmission rack 105 and the transmission outer gear ring 404, the transmission outer gear ring 404 drives the liquid outlet control frame 403 to rotate at a certain angle. Under the sliding cooperation of the transmission bar and the corresponding guide groove 402 and the sliding cooperation of the opening and closing column and the corresponding inclined groove 405, the opening and closing plate 406 moves synchronously and gradually moves away from the axis of the liquid outlet ring 401, so that the liquid outlet ring 401 opens. The cleaning and disinfection wastewater inside the cleaning support frame 102 flows through the liquid outlet pipe, through the liquid outlet ring 401 and the liquid outlet control frame 403, and then is discharged through the connecting pipe 407.

[0040] After the cleaned and disinfected capsulorhexis forceps have been transferred, when cleaning and disinfecting the next batch of capsulorhexis forceps, the drive motor is started to drive the drive bevel gear 112 to rotate in the opposite direction, the drive screw 110 to rotate in the opposite direction, and the arc-shaped transmission block 109 slides along the inside of the horizontal slide. When it moves to the intersection of the horizontal slide and the vertical slide, the cleaning inner frame 101 moves directly above the cleaning support frame 102. As the drive screw 110 continues to rotate in the opposite direction, the arc-shaped transmission block 109 slides downward along the inside of the vertical slide, thereby driving the cleaning inner frame 101 to move downward synchronously, until the cleaning inner frame 101 drives the capsulorhexis forceps to rotate. The capsule forceps are moved into the cleaning support frame 102. Simultaneously, as the inner cleaning frame 101 moves downward, the transmission rack 105 moves downward in sync. Under the meshing action of the transmission rack 105 and the transmission outer gear ring 404, the transmission outer gear ring 404 drives the liquid discharge control frame 403 to rotate in the opposite direction by a certain angle. The opening and closing plates 406 move synchronously and approach each other until they fit together to form a sealed structure. The liquid discharge ring 401 remains sealed, keeping the cleaning support frame 102 airtight. Cleaning and disinfection solution is added into the cleaning support frame 102 to perform the cleaning and disinfection operation of the descending batch of capsule forceps.

[0041] For a specific embodiment three, please refer to Figures 1-12 Based on specific embodiments one and two, specifically, the tweezers limiting component 2 includes a limiting support frame 201 slidably disposed inside the inner cleaning frame 101. The limiting support frame 201 has a hollow frame structure, which facilitates cleaning and disinfection operations while allowing impurities and contaminants to fall into the cleaning support frame 102. The limiting support frame 201 has limiting grooves on its two inner side walls. Two limiting support plates 202 are symmetrically rotatably connected inside the limiting grooves. One side of the limiting support plate 202 has an inclined sliding surface structure. An arc spring 203 is fixedly connected between the limiting support plate 202 and the limiting groove.

[0042] Furthermore, the support crossbar 204, which is engaged with the two limiting slide grooves, has an inclined sliding surface structure on its two opposite sides. The support crossbar 204 slides against the limiting support plate 202. Several lifting screws 205 are rotatably mounted on the surface of the support crossbar 204. A drive internal threaded disc 206, corresponding to each lifting screw 205, is rotatably mounted on the upper surface of the support crossbar 204. The drive internal threaded disc 206 is threadedly engaged with the corresponding lifting screw 205. The lifting screw 205 passes through the support crossbar 204. The lower end of 04 is rotatably provided with a hollow limiting crossbar 207; the hollow limiting crossbar 207 is fixedly connected to limiting extension plates on opposite sides, and several sets of guide rails 208 are symmetrically fixedly connected to the lower surface of the supporting crossbar 204. The limiting extension plates and the corresponding guide rails 208 are slidably engaged, and the hollow limiting crossbar 207 is provided with through openings on opposite sides. A first semicircle 209 is provided inside the through opening, and a transverse spring 210 is fixedly connected between the first semicircle 209 and the inner wall of the hollow limiting crossbar 207.

[0043] The bottom of the limiting support frame 201 is fixedly connected to a V-shaped limiting frame 211 that corresponds one-to-one with the hollow limiting crossbar 207. The V-shaped limiting frame 211 has two symmetrical limiting cavities. Several limiting openings are opened on the two inner side walls of the V-shaped limiting frame 211. A second semicircle 212 is provided inside the limiting opening. A limiting spring 213 corresponding to the second semicircle 212 is fixedly connected to the two inner side walls of the limiting cavity. The limiting spring 213 is fixedly connected to the corresponding second semicircle 212.

[0044] Furthermore, the horizontal adjustment component 3 includes an adjustment support rod 301 fixedly connected between the two inner side walls of the inner cleaning frame 101. An adjustment disc 302 is rotatably connected to the upper surface of the adjustment support rod 301. A submersible motor is installed on the lower surface of the adjustment support rod 301. The output shaft of the submersible motor is fixedly connected to the adjustment disc 302. An adjustment transmission column 303 is fixedly connected at the eccentric position of the adjustment disc 302. A transmission slide 304 is provided above the adjustment disc 302. The transmission slide 304 and the adjustment transmission column 303 are slidably engaged. Adjustment brackets are fixedly connected to the two opposite sides of the transmission slide 304. One end of the adjustment bracket is fixedly connected to the corresponding limiting support frame 201.

[0045] The operation process of this embodiment is as follows: The capsule tearing forceps to be cleaned are placed with the handle facing down and the clamping end facing up inside the corresponding V-shaped limiting frame 211. Under its own gravity, the sides of the capsule tearing forceps are in contact with the corresponding second semicircle 212. The supporting crossbar 204 slides downwards between the two limiting grooves. When both ends of the supporting crossbar 204 contact the corresponding limiting support plate 202, as the supporting crossbar 204 continues to move downwards, the supporting crossbar 204 and the limiting support plate 202... Under the sliding contact action, the limiting support plate 202 is squeezed by the inclined sliding surface of the supporting crossbar 204, causing the limiting support plate 202 to rotate away from the supporting crossbar 204. The arc spring 203 is compressed until the supporting crossbar 204 disengages from the limiting support plate 202. Under the elastic recovery action of the arc spring 203, the limiting support plate 202 rotates in the opposite direction, and one side of the limiting support plate 202 is in contact with the upper surface of the supporting crossbar 204, thereby limiting the position of the limiting support plate 202.

[0046] After the limiting support plate 202 completes the position limitation, the hollow limiting crossbar 207 is opposite to the corresponding endoscopic tweezers. The rotating drive internal thread disk 206, under the threaded engagement of the drive internal thread disk 206 and the corresponding lifting screw 205, and the sliding engagement of the limiting extension plate and the guide rail 208, causes the hollow limiting crossbar 207 to slide downward until the first semicircle 209 is in close contact. Under the engagement of the first semicircle 209 and the corresponding second semicircle 212, the position limitation of the endoscopic tweezers is achieved.

[0047] Once the position of the capsulorhexis forceps is defined, the forceps are immersed in the cleaning and disinfection solution in the cleaning support frame 102 through the cleaning inner frame 101. The ultrasonic cleaning equipment is then activated to clean and disinfect the forceps. During the cleaning and disinfection process, the submersible motor is activated to drive the control disc 302 to rotate. Under the sliding cooperation of the control transmission column 303 and the transmission slide 304, the transmission slide 304 moves horizontally back and forth. Under the connection of the control bracket, the two limiting support frames 201 move horizontally back and forth synchronously, which facilitates the removal of impurities and contaminants into the cleaning support frame 102 during the cleaning and disinfection process.

[0048] After cleaning and disinfection, manually move the limiting support plate 202 away from each other, the arc spring 203 is compressed, the support crossbar 204 is lifted upward, the hollow limiting crossbar 207 gradually moves away from the endoscopic forceps, the position limitation of the endoscopic forceps is released, and then take out the cleaned and disinfected endoscopic forceps.
