Description

Technical Field

[0001] This invention relates to the field of surgical instrument cleaning equipment technology, and specifically to a cleaning device for ophthalmic surgical instruments. Background Technology

[0002] Ophthalmic instruments are generally classified into general ophthalmic instruments, microsurgical instruments, ophthalmic tubular instruments, and ophthalmic optical instruments based on their structure and purpose. Among them, ophthalmic microsurgical instruments refer to precision surgical instruments mainly used in the treatment of diseases involving the inside of the eyeball, such as instruments used in cataract surgery, glaucoma surgery, and vitreoretinal surgery. These mainly include surgical scissors, forceps, tweezers, hooks, and eyelid retractors, such as microscopic toothed forceps, capsulotomy forceps, intraocular lens forceps, capsular scissors, corneal scissors, and microscopic needle holders. At the same time, ophthalmic microsurgical instruments are also characterized by a variety of special materials, intricate and complex structures, high value, rapid turnover, and meticulous maintenance.

[0003] Routine cleaning and maintenance of ophthalmic instruments includes manual cleaning and machine cleaning. Machine cleaning is mainly carried out in the hospital's central sterile supply room (CSSF), which is responsible for the collection, cleaning, sterilization, and distribution of instruments from various clinical departments. However, the cleaning machines in the CSSF are not specifically designed for ophthalmic surgery, and because most ophthalmic surgical instruments have delicate and complex structures, there is a problem of incomplete cleaning during actual use. In addition, ophthalmic surgical instruments have a high turnover rate during actual use, and it is difficult to return the instruments in a timely manner when they are centrally cleaned in the CSSF. Therefore, our hospital currently mostly uses manual cleaning. The manual cleaning procedure is as follows: first, the instruments are rinsed with running water; then, different brushes are used to scrub different instruments to remove blood and other contaminants from the joints and crevices of the instruments; then, they are rinsed with purified water to remove any water stains; finally, the instruments are placed in an autoclave for sterilization and drying. However, this method of cleaning requires a lot of time and effort and has low cleaning efficiency.

[0004] Although existing technologies disclose some cleaning devices specifically for ophthalmic surgical instruments, such as patent documents with publication numbers CN114405923B and CN114101167B, these devices all involve clamping the instruments for cleaning. After clamping, the clamped parts of the instruments are difficult to clean thoroughly. If the instruments are not clamped, some instruments are sharp, and collisions between them can easily damage them, and removing the instruments can also cause cuts to the operator. Therefore, existing cleaning devices still have the problem of incomplete cleaning. To address these technical problems, this application provides a cleaning device for ophthalmic surgical instruments that can thoroughly clean the instruments, ensuring the quality of cleaning and avoiding problems such as instrument corrosion caused by incomplete cleaning. Summary of the Invention

[0005] The present invention aims to provide a cleaning device for ophthalmic surgical instruments to solve the technical problem that existing cleaning equipment does not thoroughly clean instruments.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cleaning device for ophthalmic surgical instruments includes a main body and a cover for closing the main body. The main body has a cleaning chamber, and the cleaning chamber contains a placement mechanism for placing instruments. The placement mechanism includes a base and a placement tray mounted on the base. The placement tray has several elastic supports for fixing the instruments. The base includes a support seat and a mounting seat. The support seat is fixed to the bottom of the cleaning chamber, and the mounting seat is rotatably connected to the support seat. The placement tray is detachably mounted on the mounting seat. A rotating telescopic assembly and a brush body are disposed on the inner side of the cover. When the brush body extends from the inner side of the cover, it engages with the elastic supports and rotates relative to them. After rotating for a preset time, it drives the placement tray to rotate as well.

[0008] The principle and advantages of this scheme are:

[0009] 1. Using flexible supports to fix instruments can solve the problems of sharp object punctures and collisions and scratches between instruments when they are placed freely for cleaning. Moreover, the flexible supports have a certain degree of elasticity, which will not damage the precision instruments when fixing them compared to existing rigid clamps. This can avoid the problem of wear caused by excessive clamping force and easy fall off during cleaning due to insufficient clamping force.

[0010] 2. In addition, when the elastic support is engaged with the brush body, the brush body rotates and friction occurs between it and the elastic support, so that both the elastic support and the brush body can brush the instrument, thereby achieving thorough cleaning of the instrument joints and clamping parts. This solves the problem that existing cleaning equipment is difficult to clean the clamping parts, improves the cleaning quality of the instrument, and avoids problems such as instrument corrosion caused by incomplete cleaning.

[0011] 3. The brush body is retractable and mounted on the cover. When not being brushed, the brush body is retracted and located inside the cover, which will not affect the cleaning work inside the cleaning chamber. When brushing is required, the brush body extends from the inside of the cover and is embedded in the elastic support. After brushing is completed, it retracts back into the inside of the cover.

[0012] 4. Rotate the mounting base to the support base. After the brushing is completed, the brush body rotates and drives the placement plate to rotate together, which makes it easier to shake out the cleaning water in the elastic support. Since the brush body is embedded in the elastic support, the instrument will not shift or collide with each other during rotation, which is safer.

[0013] In summary, the flexible support and brush body of this application can simultaneously achieve functions such as support and fixation, brushing, limiting, and rotational centrifugation without damaging the instrument and ensuring thorough cleaning.

[0014] Preferably, as an improvement, the placement tray is provided with a guide groove, a limit block is provided in the guide groove, and the brush body is provided with a guide rod corresponding to the guide groove. The guide rod is slidably connected to the guide groove. When the guide rod contacts the limit block, the guide rod rotates and drives the placement tray to rotate together.

[0015] Beneficial effects: By setting guide rods and guide grooves, the brush body can be guided and limited during rotation, ensuring the stability of brushing. In addition, when the guide rod contacts the limit block, it indicates that the brushing work is over, and the brush body begins to rotate together with the placement plate to perform centrifugal motion, thereby throwing the brushing water out from the elastic support.

[0016] Preferably, as an improvement, the rotary telescopic assembly includes a telescopic rod and a rotary motor. A mounting block is provided at the front end of the telescopic rod, the rotary motor is disposed inside the mounting block, the power output shaft of the rotary motor is fixedly connected to the brush body, and the brush body is rotatably connected to the mounting block.

[0017] Beneficial effects: The telescopic rod drives the brush body and mounting block to extend and retract within the cleaning chamber. The rotating motor drives the brush body to rotate, and the rotation speed of the rotating motor can be adjusted to set different rotation speeds according to the different instruments being cleaned.

[0018] Preferably, as an improvement, the elastic support includes a limiting support and a vibration support, and the two types of supports are arranged at intervals.

[0019] Beneficial effects: The limiting support is mainly used to limit and fix the instrument, ensuring that the instrument does not shift during washing. The vibrating support is softer and thinner than the limiting support. While limiting and fixing, it vibrates and rubs against the surface of the instrument, thereby washing the clamping part of the instrument.

[0020] Preferably, as an improvement, the mounting base is provided with a vibration component, which is used to drive the placement tray to vibrate, and when the elastic support vibrates, it rubs against the contact part of the instrument.

[0021] Beneficial effects: When the placement tray vibrates, both the vibrating support and the limiting support will vibrate. Since the vibrating support is softer and thinner than the limiting support, the vibration levels of the two are different. The limiting support produces a smaller vibration, which will not cause the instrument to shift. The vibrating support vibrates more, but because it is softer and thinner, it mainly cleans the instrument during vibration and is not enough to cause the instrument to shift. Therefore, the two supports work together to thoroughly clean the instrument without causing it to shift during cleaning.

[0022] Preferably, as an improvement, the elastic support is an inverted cone-shaped structure, and the placement plate is also provided with several guide grooves.

[0023] Beneficial effects: The inverted cone shape can limit the longitudinal movement of the instrument, and the guide channel facilitates the drainage of cleaning water. Furthermore, the guide channel reduces the contact area between the bottom of the instrument and the placement tray when it is placed on the tray, further ensuring the thoroughness of the cleaning.

[0024] Preferably, as an improvement, the elastic support on the placement tray is divided into several areas.

[0025] Beneficial effect: By dividing the placement tray into sections, instruments can be placed in different areas according to their type.

[0026] Preferably, as an improvement, the cover body is further provided with a controller, and the surface of the cover body is provided with an operation panel that is electrically connected to the controller.

[0027] Beneficial effects: The cleaning time of the cleaning chamber can be set through the control panel, and the rotation speed of the brush body can be set according to the instruments being cleaned. The start and stop operations can also be performed through the control panel.

[0028] Preferably, as an improvement, the top of the main body and the cover are also provided with electromagnets that attract each other. The top of the main body is also provided with a power interface, and the cover is provided with a plug. When the plug is inserted into the power interface, the two electromagnets are energized and attract each other.

[0029] Beneficial effect: When the cover is placed on the main body and the plug on it is inserted into the power interface, the two electromagnets attract each other, thereby fixing the cover on the main body and closing it, preventing water from overflowing from the cleaning chamber during cleaning.

[0030] Preferably, as an improvement, the inner wall of the cleaning chamber is further provided with a number of rinsing nozzles for rinsing instruments.

[0031] Beneficial effect: The addition of rinsing nozzles facilitates the rinsing of instruments. Attached Figure Description

[0039] The following detailed description illustrates the specific implementation method:

[0040] The reference numerals in the accompanying drawings include: body 1, opening 11, cleaning chamber 12, rinsing nozzle 121, water inlet pipe 13, drain pipe 14, cover 2, plug 21, power interface 22, electromagnet 23, base 3, mounting base 31, support base 32, placement tray 4, elastic support column 41, limiting support column 411, vibration support column 412, guide channel 42, guide groove 43, limiting block 431, rotating telescopic assembly 5, telescopic rod 51, mounting block 52, rotating motor 521, brush body 53, guide rod 531, and operation panel 6.

[0041] Example 1

[0042] like Figure 1-2 As shown, a cleaning device for ophthalmic surgical instruments includes a body 1 and a cover 2 for covering the body 1. In this embodiment, the body 1 can be an existing desktop ultrasonic cleaner with ultrasonic cleaning function. The body 1 can be square or cylindrical, and can be configured in various sizes to meet the cleaning needs of ophthalmic surgical instruments. An opening 11 is opened at the top of the body 1, and the cover 2 is used to cover the opening 11. A cleaning chamber 12 is provided inside the body 1. A water inlet pipe 13 and a drain pipe 14 communicating with the cleaning chamber 12 are also provided on the side wall of the body 1. The drain pipe 14 is located at the bottom. The water inlet pipe 13 can be connected to different water source interfaces according to the cleaning needs. In this embodiment, the bottom of the cleaning chamber 12 is inclined to facilitate drainage.

[0043] like Figure 2As shown, the cleaning chamber 12 is equipped with a placement mechanism for placing instruments. The placement mechanism includes a base 3 and a placement tray 4 disposed on the base 3. The placement tray 4 can be configured in different shapes, such as square, elliptical, or circular. This embodiment uses a circular shape as an example for detailed description. Specifically, the placement tray 4 is provided with several elastic supports 41 for fixing instruments. The elastic supports 41 have an inverted conical structure, which can longitudinally limit the instruments. In this embodiment, the elastic supports 41 can be made of silicone material. The placement tray 4 is also provided with several guide grooves 42, and the depth of the guide grooves 42 gradually increases from the center of the placement tray 4 outward, so that the bottom of the guide grooves 42 forms a downward sloping surface, which facilitates drainage. In addition, due to the setting of the guide grooves 42, the contact area between the instruments and the bottom of the placement tray 4 is reduced, which facilitates ultrasonic cleaning of the bottom surface of the instruments. The base 3 includes a support 32 and a mounting base 31. The support 32 is fixed to the bottom of the cleaning chamber 12. The mounting base 31 is rotatably connected to the support 32. The placement tray 4 is detachably mounted on the mounting base 31. Specifically, the mounting base 31 is provided with a slot, and the bottom of the placement tray 4 is provided with a protrusion that engages with the mounting base 31, making it easy to disassemble and replace the placement tray 4.

[0044] The inner side of the cover 2 is provided with a rotating telescopic component 5 and a brush body 53 provided at the power output end of the rotating telescopic component 5. In this embodiment, the brush body 53 is a disc-shaped soft brush, or different types of brushes can be replaced according to the cleaning equipment. When the brush body 53 extends out from the inner side of the cover 2, it is engaged with the elastic support 41 and rotates relative to the elastic support 41. When it rotates for a preset time, it drives the placement plate 4 and the mounting base 31 to rotate together.

[0045] In this embodiment, the rotary telescopic assembly 5 includes a telescopic rod 51 and a rotary motor 521. The telescopic rod 51 can be an electric telescopic rod or a cylinder. Specifically, an installation cavity is provided inside the cover 2, and the telescopic rod 51 is installed in the installation cavity. The power output end of the telescopic rod 51 is welded or bolted to an installation block 52. A motor cavity is provided at the bottom of the installation block 52, and the rotary motor 521 is fixedly installed in the motor cavity. The power output shaft of the rotary motor 521 is fixedly connected to the brush body 53, and the brush body 53 is rotatably connected to the installation block 52. In this embodiment, the bottom of the cover 2 is also provided with a storage cavity for storing the brush body 53. When not in use, the brush body 53 is located in the storage cavity. When in use, the telescopic rod 51 extends to push the brush body 53 and the installation block 52 downwards, and then the rotary motor 521 drives the brush body 53 to rotate. Figure 2 As shown, in this embodiment, a guide groove 43 is provided on the outer edge of the placement tray 4, and a limit block 431 is provided in the guide groove 43. A guide rod 531 corresponding to the guide groove 43 is provided on the edge of the brush body 53. The guide rod 531 is slidably connected to the guide groove 43. When the guide rod 531 contacts the limit block 431, the guide rod 531 rotates and drives the placement tray 4 to rotate together.

[0046] Specifically, when the brush on the brush body 53 is engaged with the elastic support 41, the guide rod 531 is inserted into the guide groove 43. At this time, the rotary motor 521 drives the brush to repeatedly brush the instrument by rotating forward and backward. The brush rotates and rubs against the elastic support 41, so that both the elastic support 41 and the brush body 53 can brush the instrument, thereby achieving thorough cleaning of the instrument nodes and clamping parts. After brushing, the brush moves in one direction, so that the guide rod 531 contacts the limiting block 431 and pushes the limiting block 431 to rotate. The rotation of the limiting block 431 drives the entire placement plate 4 to rotate, thereby causing the mounting base 31 to rotate relative to the support base 32. During the rotation, the cleaning water is thrown out from the gap between the brush and the elastic support 41 and the guide groove 42. Since the brush is engaged in the elastic support 41, the instruments will not shift or collide during rotation.

[0047] The method of using a cleaning device for ophthalmic surgical instruments is as follows:

[0048] Step 1: First, place different surgical instruments on the placement tray 4, and use the elastic support 41 to limit and fix the instruments to avoid collisions or scratches between the instruments. Then, use the cover 2 to cover the opening 11 at the top of the body 1 to prevent water from splashing out during cleaning.

[0049] Step 2: Connect the water inlet pipe 13 to the water source interface, and input hot water or cleaning water with cleaning agent into the cleaning chamber 12 as needed to soak the instruments and initially remove bloodstains, tissues or other contaminants adhering to the instruments. After soaking, drain the water through the drain pipe 14.

[0050] Step 3: Rinse the instrument. In this embodiment, a rinsing nozzle 121 is provided on the inner wall of the cleaning chamber 12. The instrument is rinsed using the rinsing nozzle 121 to remove contaminants that have fallen off and adhered to the elastic support 41 or the surface of the instrument after soaking.

[0051] Step 4: Start the telescopic rod 51. The brush extends from the bottom of the cover 2 and engages with the elastic support 41. Then, the rotary motor 521 drives the brush to rotate clockwise and counterclockwise alternately to thoroughly clean the nodes and clamping parts of the instrument. After cleaning, the brush body 53 rotates in one direction and presses against the limiting block 431, pushing the limiting block 431 to rotate together, thereby driving the placement plate 4 to rotate and centrifugally, splashing out the cleaning water.

[0052] Step 5: Replace the water source interface on the water inlet pipe 13. Specifically, the water inlet pipe 13 can be set as a T-shaped pipe, with the other two branch pipes connected to the tap water source interface and the purified water source interface respectively. When the water source needs to be changed, open the corresponding branch pipe. In this step, open the purified water source interface and close the tap water source interface. Use purified water to perform a final rinse on the instruments to remove residual cleaning water from the instruments and avoid leaving water stains on the instruments during subsequent high-temperature sterilization, which would affect subsequent microsurgical operations.

[0053] Step 6: After the final rinse is completed, open the cover 2, take out the instrument, and place the instrument into the high-pressure steam sterilizer for disinfection and sterilization.

[0054] Example 2

[0055] The difference between this embodiment and Embodiment 1 is that, as Figure 3 As shown, the elastic support 41 includes a limiting support 411 and a vibrating support 412, with the two types of supports spaced apart. The limiting support 411 is mainly used to limit and fix the instrument, ensuring that the instrument does not shift during washing. The vibrating support 412 is softer and thinner than the limiting support 411. While limiting and fixing the instrument, it vibrates and rubs against the surface of the instrument, thereby washing the clamping part of the instrument. Specifically, a vibration component (not shown in the figure) is provided in the mounting base 31. The vibration component can be a vibration motor. The vibration component drives the placement tray 4 to vibrate. When the placement tray 4 vibrates, the limiting support 411 and the vibrating support 412 on it vibrate and rub against the contact part of the instrument.

[0056] When the placement tray 4 vibrates, both the vibrating support 412 and the limiting support 411 will vibrate. Since the vibrating support 412 is softer and thinner than the limiting support 411, the vibration levels of the two are different. The limiting support 411 produces a smaller vibration, which will not cause the instrument to shift. The vibrating support 412 vibrates more, but because it is softer and thinner, it mainly cleans the instrument during vibration and is not enough to cause the instrument to shift. Therefore, the two supports work together to thoroughly clean the instrument without causing it to shift during cleaning.

[0057] Example 3

[0058] The difference between this embodiment and Embodiment 2 is that, as Figure 4-5 As shown, the elastic support 41 on the placement tray 4 is divided into several areas, which can be used to place instruments in different areas according to their type; for example... Figure 5 As shown; when the partitioning method is a concentric circle shape, the brush body 53 can also be set to the corresponding shape. For example, the inner circle of the brush body 53 can be set to a fine soft brush for brushing the instruments on the inner circle of the placement tray 4, and the outer circle can be a fine soft large brush for brushing the instruments placed on the outer circle of the placement tray 4.

[0059] Example 4

[0060] The difference between this embodiment and Embodiment 3 is that, as Figure 6 As shown, electromagnets 23 that attract each other are also provided on the top of the main body 1 and the cover 2. A power interface 22 is also provided on the top of the main body 1, and a plug 21 is provided on the cover 2. When the plug 21 is inserted into the power interface 22, the two electromagnets 23 are energized and attract each other; thereby fixing the cover 2 on the main body 1 to achieve closure, preventing water from overflowing from the cleaning chamber 12 during cleaning, or preventing the cover 2 from detaching from the main body 1 during the cleaning process.

[0061] Example 5

[0062] The difference between this embodiment and embodiment four is that, as Figure 7 As shown, a controller is also provided inside the cover 2, and an operation panel 6 electrically connected to the controller is provided on the surface of the cover 2. The cleaning time of the cleaning chamber 12 can be set through the operation panel 6, and the rotation speed of the brush body 53 can be set according to the instruments being cleaned, or the start and stop operations can be performed through the operation panel 6. The controller and operation panel 6 can realize intelligent settings. When using it, you only need to press the start button to carry out a series of subsequent cleaning. This intelligent control technology has not been improved and is existing technology, so it will not be described in detail here.

[0063] The above descriptions are merely embodiments of the present invention, and common knowledge such as specific technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
