Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a device for preoperative eye cleaning and anesthesia in ophthalmic surgery. Background Technology

[0002] Ophthalmic surgeries, such as cataract extraction, refractive correction, and glaucoma treatment, are among the most precise and widely performed procedures in modern medicine. To ensure surgical success and minimize the risk of postoperative complications such as infection, preoperative eye preparation is crucial. This preparation typically includes two core components: eye cleaning and topical anesthesia. Eye cleaning aims to thoroughly remove microorganisms, secretions, and dust from the surface and surrounding areas of the eyeball, creating a sterile surgical environment. Topical anesthesia involves instilling anesthetic drops to numb the nerve endings in the cornea and conjunctiva, eliminating pain and discomfort during the procedure and ensuring the patient's smooth cooperation.

[0003] In current clinical practice, the aforementioned preoperative preparation procedures largely rely on manual operation by medical staff. Typically, medical staff use tools such as droppers, syringes, or cotton swabs soaked in medication to manually instill or apply cleaning solutions and anesthetic eye drops to the patient's eyes. While this traditional method has been used for a long time, it has inherent and insurmountable limitations in its operation.

[0004] First, this procedure, which relies entirely on manual manipulation, presents significant uncertainties in controlling the dosage of the medication. Medical staff, relying on experience, struggle to precisely control the volume of fluid administered each time. Excessive medication not only leads to waste but may also spill onto the patient's skin around the eyes, causing irritation or discomfort; insufficient dosage, on the other hand, may result in incomplete cleaning or inadequate anesthesia, creating potential complications for the surgery. This uncontrollable dosage directly impacts the standardization of preoperative preparation.

[0005] Secondly, manual operation makes it difficult to ensure uniform coverage of the medication across the entire surface of the eye, especially the cornea. Factors such as the droplet's landing point, diffusion rate, and the patient's blinking reflex can all lead to uneven medication distribution, potentially resulting in areas with concentrated medication while others are under-covered. This unevenness is particularly problematic for topical anesthesia, potentially leading to inconsistent anesthetic depth. Patients may still experience stinging or discomfort during surgery, affecting their cooperation and interfering with delicate surgical procedures.

[0006] Therefore, the core deficiency of existing technologies lies in their commonly used open, non-quantitative manual administration method, which fails to organically combine the three key elements of precise positioning of the ocular area, quantitative delivery of the medication, and automated control of the operational process. This method not only increases the workload of medical staff and reduces the efficiency of preoperative preparation, but more importantly, its inherent deficiencies in dosage accuracy, distribution uniformity, and process standardization directly affect the quality and reliability of ophthalmic surgical preparation.

[0007] Therefore, this invention proposes a preoperative eye cleaning and anesthesia device for ophthalmic surgery to address the shortcomings of existing technologies. Summary of the Invention

[0008] In view of the problems existing in the preoperative eye cleaning anesthesia process for ophthalmic surgery, such as heavy reliance on manual operation, inability to achieve precise quantitative delivery of medication, cumbersome and non-standardized operation procedures, and poor patient experience, the present invention aims to provide an ophthalmic surgery preoperative eye cleaning anesthesia device with an improved structure that can effectively solve the above problems.

[0009] Its specific structure includes a main body serving as the core support platform, a strap for securing the device to the user's head, a frame for precise positioning and environmental conformity, a reservoir for storing functional liquids, and a liquid nozzle for performing liquid injection. The core innovation of this invention lies in the highly integrated execution processor serving as the central control unit, a precision infusion pump serving as a precision actuator, and an infusion line connecting the various fluid components within the main body of the device.

[0010] The processor is not simply housed inside the device, but rather features a sophisticated mounting and support structure. This structure includes a processor mounting plate serving as the circuit carrier, and a core processor chip soldered to the mounting plate. The processor mounting plate is securely attached to the inner wall or internal reinforcing ribs of the device body via rigid connecting rods. This structure not only ensures the stability of the electronic core during device movement or vibration but also provides optimized space for heat dissipation and wiring on the circuit board.

[0011] Furthermore, the aforementioned components form a cohesive and integrated whole. The two ends of the straps are connected to both sides of the device body, preferably via pre-set strap slots on the device body, to achieve a stable and adjustable fit. The rear contour of the fitting frame is ergonomically designed to fit snugly around the user's eye sockets. It is fixedly connected to the user-facing side of the device body using methods such as ultrasonic welding or environmentally friendly adhesives, forming a sealed overall structure. The liquid storage device is detachably connected to the device body, and its outlet is fluidly connected to the internal flow path of the device body via a self-sealing valve. The liquid nozzle, preferably a microporous nozzle capable of producing micron-level atomized particles, is firmly fixed to the inner wall of the fitting frame. The precision infusion pump, preferably a micro-peristaltic pump or piezoelectric pump with high metering accuracy, is housed in an independent compartment inside the device body and electrically connected to the processor to accurately receive and execute drive control commands from the processor. The infusion line, serving as a liquid delivery channel, has one end sealed to the outlet of a precision infusion pump and the other end connected to the inlet of a liquid nozzle. This creates a fully enclosed and controlled precision liquid delivery path within the entire device, starting from the storage device, precisely driven by the precision infusion pump, and finally output through the liquid nozzle.

[0012] To further optimize the technical performance and user experience of this invention, the following preferred technical solutions are also included: Preferably, the strap is made of elastic material and has a length adjustment mechanism. This design allows the device to adapt to users with different head circumferences and ensures stability and comfort during wear.

[0013] Preferably, the preoperative eye cleaning and anesthesia device for ophthalmic surgery also integrates a complete eye environment protection system, including a protective shield and a light shield. The protective shield is made of highly transparent medical-grade polycarbonate material, and its edges are sealed and fixed to the front side of the fitting frame away from the main body of the device through ultrasonic welding or other methods, forming an isolated microenvironment for the eye. The light shield is made of opaque, lightweight material and is installed on the outer periphery of the fitting frame through a snap-fit ​​structure, which can block ambient light from interfering with the user.

[0014] Preferably, the installation position and spray angle of the liquid nozzle are precisely designed, with its nozzle facing the geometric center area enclosed by the fitting frame, and its spray axis forming a preset angle with the normal of the user's eyeball surface, so as to ensure that the sprayed fine liquid mist can cover the entire cornea and conjunctiva area in the gentlest and most uniform way, avoiding direct impact on the pupil area, thereby reducing patient discomfort.

[0015] Preferably, the preoperative eye cleaning and anesthesia device for ophthalmic surgery further includes a receiver for receiving wireless commands. This receiver is fixed to the edge of the processor mounting plate via a separate mounting rod, and is electrically connected to the processor, allowing medical personnel to remotely control the device via a handheld terminal or a central control console.

[0016] Preferably, the outer casing of the liquid storage device is equipped with an integrated human-machine interface. This interface specifically includes a touchscreen display capable of showing equipment status, operating parameters, remaining liquid volume, and several buttons for functions such as start-up, emergency stop, or mode switching, providing the operator with rich and flexible interactive options.

[0017] Preferably, the device also includes a wired connection path. The main body of the device has a control interface for wired data transmission, and the liquid storage device has a compatible control connector, enabling a pluggable electrical connection via a data cable. This interface can be used not only for wired control of external devices but also for firmware upgrades and maintenance.

[0018] Preferably, an adjustment button is also provided on the top outer surface of the main body of the device. This adjustment button is electrically connected to the processor, allowing the operator to perform quick operations such as fine-tuning the injection dosage without interrupting the main process.

[0019] Preferably, the liquid storage device also has a structurally optimized liquid inlet. This inlet is located at the top of the liquid storage device and is equipped with a threaded cap with a silicone sealing ring, ensuring a reliable seal in any orientation and preventing liquid leakage and contamination.

[0020] This invention provides a device for preoperative eye cleaning and anesthesia in ophthalmic surgery. It has the following beneficial effects: 1. This invention integrates the execution processor, precision infusion pump, liquid storage device, and liquid nozzle into a single wearable device. The processor precisely controls the start / stop, flow rate, and total delivery volume of the precision infusion pump according to a preset program or real-time instructions. This solves the problems of uncontrollable dosage, serious waste, and inconsistent anesthesia or cleaning effects caused by manual infusion of medication in the prior art. It achieves the technical effects of automation, standardization, and precise dosage control of the ocular infusion process, greatly improving the standardization and reliability of preoperative preparation.

[0021] 2. This invention solves the problems of difficulty in precise positioning during manual operation, easy liquid loss, and easy contamination of the periorbital area in the prior art by designing a fitting frame that can closely fit the contour of the user's eye socket and using it as the installation reference for the liquid nozzle and protective device. It achieves the technical effect of stably positioning the device in the target area of ​​the eye and ensuring that the atomized liquid flow can be precisely guided, thereby ensuring the maximum utilization rate of the liquid and the concentration of the effect.

[0022] 3. By integrating multiple human-computer interaction and control pathways such as a local touch screen, physical shortcut buttons, wired data interfaces, and wireless signal receivers, this invention solves the problems of existing technologies, such as single operation methods, inability to perform intelligent management and data recording, and difficulty in integrating into modern digital medical processes. It provides medical staff with flexible, convenient, and multi-dimensional equipment operation options, facilitating programmed settings or remote intervention according to actual clinical needs, and achieving the technical effects of intelligent equipment and convenient operation.

The function of this interface is to provide a stable wired control or firmware upgrade channel. At the same time, in order to realize remote wireless control, the main body 1 also integrates a receiver 13. The receiver 13 has a Bluetooth low power wireless signal receiving module structure. It is fixed to the edge of the processor mounting plate 19 by a metal mounting rod 12 to reduce signal shielding. The receiver 13 is electrically connected to the processor 20. Its function is to receive wireless commands from the handheld remote control or the central control console. This human-machine interaction and command receiving system ensures the high flexibility and convenience of equipment operation and the redundancy and reliability of system command sources.

[0031] Based on the above embodiments, this invention patent may further include the following preferred technical solutions: As a preferred embodiment, to further improve wearing comfort and adaptability, the strap 2 is made of highly elastic, biocompatible medical-grade silicone, and its length adjustment mechanism is a combination of a sliding D-ring and a Velcro closure, allowing the user to quickly put it on and precisely adjust the tightness. As another preferred embodiment, to achieve the optimal spraying effect, the nozzle axis of the liquid nozzle 8 forms a preset angle of 15-30 degrees with the normal to the surface of the user's eyeball, ensuring that the sprayed atomized liquid can contact the eyeball in the gentlest way and evenly cover the corneal area, avoiding direct contact with the pupil and causing discomfort. As another preferred embodiment, to ensure the sealing and easy replacement of the liquid storage device 5, the liquid inlet 16 for replenishing or replacing the liquid is located on the top of the liquid storage device 5 and is equipped with a threaded cap with a silicone sealing ring, ensuring no liquid leakage in any posture.

[0032] The working principle of the preoperative eye cleaning and anesthesia device for ophthalmic surgery of this invention is as follows: First, in the preparation stage, medical staff use the straps 2 to securely place the main body 1 of the device on the patient's head, ensuring that the silicone contour of the fitting frame 6 fits tightly against the patient's eye socket area, completing the precise physical positioning of the device. At this time, the protective cover 3 and the light shield 17 create an isolated, dark, and comfortable preparation environment for the eyes. Second, in the command issuance stage, the operator can input operation commands in various ways, such as selecting and starting a preset cleaning or anesthesia program through the human-machine interface 9 on the liquid storage device 5, or issuing a wireless command through a handheld remote control. This command is received by the receiver 13 and transmitted to the processor 20. In special cases, fine-tuning can also be performed through the adjustment button 18 or wired control through the control interface 15. Next, in the signal processing and execution stage, regardless of the source of the instruction, it ultimately converges to the processor 20 within the execution processor 4. Upon receiving the instruction signal, the processor 20, mounted on the processor mounting plate 19, analyzes it according to a preset program or real-time parameters and generates a precise pulse width modulation control electrical signal, which is then sent to the motor of the precision infusion pump 7. Finally, in the fluid delivery stage, the precision infusion pump 7 starts precisely upon receiving the control electrical signal and operates at the set speed, drawing a fixed amount of fluid from the storage device 5 and pressurizing it through the infusion line 10 to the liquid nozzle 8 fixed on the fitting frame 6. The fluid is atomized after passing through the microporous structure of the liquid nozzle 8, spraying it in a uniform and fine mist onto the target area of ​​the patient's eye, efficiently completing the cleaning or anesthesia operation. After the entire process is completed, the processor 20 controls the precision infusion pump 7 to stop working. Through the coordinated action of all components of the entire system, this invention solves the problems of inaccurate manual fluid dosage, non-standardized operating procedures, poor patient experience, and potential cross-infection risks in the prior art.
