An eye care device

Abstract

This utility model discloses an eye care device, including a handle and a gripping section at the lower end of the handle for grasping. An extension rod is connected to the lower middle of the gripping section, and an eye blade is located at the lower end of the extension rod. An air chamber is formed inside the upper middle of the handle, and a connecting cylinder is located at the lower end of the air chamber. Air holes are formed at both ends of the connecting cylinder, and an air bladder is located on the outer side of the connecting cylinder. The inflated air bladder fits snugly against the fingers, increasing the contact area between the fingers and the handle. According to the principle of pressure, under the same pressure, an increased contact area results in decreased pressure, making the grip more stable. Even if the hands are slightly sweaty during surgery, the handle can be effectively prevented from slipping, ensuring the safety of the surgical procedure. For example, during resection, if resistance from eye tissue is suddenly encountered, a stable grip ensures that the eye blade will not deviate from the predetermined cutting trajectory due to hand slippage.

Description

Technical Field

[0001] This utility model belongs to the technical field of eye surgery, specifically relating to an eye care device. Background Technology

[0002] An ophthalmic scalpel is a precision instrument specifically designed for ophthalmic surgery, primarily used to cut ocular tissues such as the cornea, conjunctiva, or lens. Its technological background dates back to the mid-20th century. With the increasing demand for more refined and minimally invasive ophthalmic surgery, traditional surgical instruments could no longer meet the high precision requirements. The design of ophthalmic scalpels incorporates microsurgical techniques, typically employing ultra-thin blades and high-strength materials such as stainless steel or titanium alloys to ensure both precision and safety in cutting.

[0003] Traditional ophthalmic scalpel grips are usually made of rigid materials. During surgery, if the hands sweat or encounter unexpected resistance, the grip can easily slip, affecting surgical safety. Utility Model Content

[0004] The purpose of this invention is to provide an eye care device to solve the problem in the background art where the handle of a traditional eye knife is usually made of hard material, and during surgery, if the hand sweats or encounters unexpected resistance, the handle is prone to slipping, affecting the safety of the surgery.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an eye care device, comprising a handle and a gripping section disposed at the lower end of the handle for gripping;

[0006] An extension rod is connected to the lower middle of the gripping section, and an eye blade is provided at the lower end of the extension rod;

[0007] An air chamber is provided in the middle of the upper side of the grip, and a connecting tube is provided at the lower end of the air chamber. Air holes are provided at the front and rear ends of the connecting tube, and an air bag is provided on the outer side of the connecting tube.

[0008] A cylindrical lifting rod is provided in the middle of the upper side of the air chamber, a sealing plug is provided at the lower end of the lifting rod, and a ball is provided at the upper end of the lifting rod.

[0009] Preferably, the sealing plug is in close contact with the inner wall of the air chamber, and the upper connection between the lifting rod and the handle is threaded.

[0010] Preferably, the lifting rod can be moved up and down by rotating within the grip via a thread, and the diameter of the sphere is larger than the diameter of the lifting rod.

[0011] Preferably, the connecting cylinder divides the grip rod into an upper section and a lower section, the air chamber is opened in the upper section of the grip rod, and the upper and lower ends of the grip rod are connected to the connecting cylinder by a threaded connection.

[0012] Preferably, the airbag is connected to the connecting cylinder via a flange connection and upper and lower end handles, and a sealing gasket is provided at the connection point for sealing.

[0013] Preferably, the airbag can expand into a ring shape outside the connecting cylinder, the outer side of the grip is provided with friction texture, and the upper part of the grip is recessed with a pressing section.

[0014] Compared with the prior art, the present invention provides an eye care device with the following beneficial effects:

[0015] 1. Different ocular growth removal surgeries have varying requirements for precision and stability. By providing freely combinable upper and lower grips, medical staff can choose the optimal combination based on the specific situation. For example, for the extremely delicate removal of growths on the surface of the eyeball, a thinner and shorter grip can be used to achieve more precise operation; while for locations such as the eyelid margin, where greater force application space is required, a thicker and longer grip can be selected to meet the needs of different surgical scenarios and greatly improve the applicability of the surgery.

[0016] Furthermore, traditional ophthalmic scalpels often require replacement of the entire instrument if the handle is damaged or unsuitable for a specific surgery. This new ophthalmic scalpel, however, only requires replacement of the damaged or unsuitable handle, eliminating the need to discard the entire device and reducing procurement costs. Simultaneously, the same device can meet various surgical needs by replacing the handle, improving equipment efficiency and avoiding resource waste.

[0017] 2. Users can adjust the device's center of gravity closer to the end of the ocular blade. During the removal of ocular growths, medical staff can more sensitively perceive the contact force between the blade and the growth, much like using a well-balanced brush to precisely apply ink with a light touch. This precise force control effectively avoids accidental damage to surrounding normal eye tissues, improving the success rate of the surgery and reducing surgical risks.

[0018] A proper center of gravity position allows for more natural and reasonable hand exertion. During prolonged surgeries, medical staff do not need to exert excessive force to maintain the stability of the surgical blade, reducing hand muscle fatigue. For example, in complex vegetation removal surgeries, which may require continuous operation for half an hour or even longer, the center of gravity adjustment function allows medical staff to maintain a relaxed operating state throughout the process, thereby improving the continuity and accuracy of the surgical procedure.

[0019] 3. The inflated air bladder fits snugly against the fingers, increasing the contact area between the fingers and the grip. Based on the principle of pressure, under the same pressure, a larger contact area results in lower pressure, making the grip more stable. Even if the hands are slightly sweaty during surgery, it effectively prevents the grip from slipping, ensuring the safety of the surgical procedure. For example, during resection, if sudden resistance from eye tissue is encountered, a stable grip ensures that the surgical blade will not deviate from the intended cutting trajectory due to hand slippage.

[0020] Gripping a hard grip for extended periods can easily cause finger pain, numbness, and other discomfort, and may even lead to localized damage. The cushioning effect of the airbag disperses the pressure on the fingers, acting like a soft pad. During multiple ocular growth removal surgeries, medical staff were able to maintain a comfortable finger position, reducing the risk of occupational injury and improving their work comfort and efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figure 1-5 An eye care device is shown, including a handle 1 and a gripping section 3 disposed at the lower end of the handle 1 for gripping;

[0029] An extension rod 4 is connected to the lower middle of the gripping section 3, and an eye blade 5 is provided at the lower end of the extension rod 4;

[0030] An air chamber 11 is provided in the middle of the upper side of the grip 1. A connecting tube 12 is provided at the lower end of the air chamber 11. Air holes 13 are provided at the front and rear ends of the connecting tube 12 respectively. An air bag 8 is provided on the outer side of the connecting tube 12.

[0031] A cylindrical lifting rod 7 is provided in the middle of the upper side of the air chamber 11, a sealing plug 10 is provided at the lower end of the lifting rod 7, and a ball 6 is provided at the upper end of the lifting rod 7.

[0032] In this embodiment, after washing their hands and putting on sterile gloves, the user can hold the ophthalmic scalpel and, with the aid of a surgical magnifying glass or microscope, precisely aim the scalpel 5 at the eye growth. Using the appropriate operating distance provided by the extension rod 4, the user can slowly and steadily move the scalpel 5 to cut. During the cutting process, the user can flexibly change the direction of movement of the scalpel 5 by adjusting the center of gravity, accurately removing the growth.

[0033] like Figure 1-5 As shown, the sealing plug 10 and the inner wall of the air chamber 11 are in close contact. The upper connection of the lifting rod 7 and the handle 1 is connected by threads. The lifting rod 7 can rotate inside the handle 1 to move up and down. The diameter of the ball 6 is larger than the diameter of the lifting rod 7. The connecting cylinder 12 divides the handle 1 into an upper section and a lower section. The air chamber 11 is opened in the upper section of the handle 1. The upper and lower handles 1 are connected to the connecting cylinder 12 by threads. The airbag 8 is connected to the upper and lower handles 1 on the connecting cylinder 12 by a flange connection. A sealing gasket ring is provided at the connection for sealing. The airbag 8 can expand into a ring shape outside the connecting cylinder 12 when air is applied. Friction texture 2 is provided on the outer side of the handle 1, and a pressing section 9 is recessed at the upper front side of the upper section of the handle 1.

[0034] Preferably, the user can select the appropriate length and thickness of the upper and lower grip rods 1 according to their own needs. The upper and lower grip rods 1 are then connected to the two ends of the connecting cylinder 12 via threads to complete the assembly of the grip rods 1. During the connection process, it is essential to ensure a tight threaded connection to prevent loosening during use.

[0035] Rotating the ball 6 on the upper side of the lifting rod 7 causes the lifting rod 7 to move up and down within the air chamber 11, as the lifting rod 7 is connected to the upper side of the grip 1 via a threaded connection. The sealing plug 10 connected to the lower side of the lifting rod 7 moves accordingly, thus changing the center of gravity of the device. For example, when more flexible operation of the eye knife 5 is required, the lifting rod 7 can be moved upwards, bringing the center of gravity closer to the upper side of the grip 1; if more stable operation is required, the lifting rod 7 can be moved downwards, bringing the center of gravity closer to one end of the eye knife 5.

[0036] Continuing to rotate the ball 6 further compresses the gas within the air chamber 11 by the sealing plug 10. The air chamber 11 is connected to the external air bladder 8 through the air hole 13 on the connecting cylinder 12. The compressed gas enters the air bladder 8 through the air hole 13, causing the air bladder 8 to gradually inflate. When the air bladder 8 inflates to a suitable size, such as comfortably fitting the fingers and providing sufficient support for gripping, the rotation of the ball 6 is stopped.

[0037] Additionally, the user holds the handle 1 with their thumb and other fingers gripping it, while the middle finger can be placed on the pressing section 9. The eye blade 5 is located at the lower end of the extension rod 4, aimed at the area requiring eye care, allowing for smooth and accurate cutting or other care actions. During operation, the friction texture 2 on the outer side of the handle 1 increases the friction between the hand and the handle 1, preventing it from slipping; the airbag 8 provides cushioning for the fingers, preventing injury from prolonged pressure, while also enhancing the grip and making the operation more stable.

[0038] Preferably, the design of the connecting cylinder 12 allows the grip bar 1 to be divided into upper and lower sections, and the upper and lower sections of the grip bar 1 are tightly connected by a threaded connection, utilizing the relationship between the helix angle of the thread and friction. This connection method allows users to freely combine different grip bars 1 to adapt to different usage scenarios and personal habits, meeting diverse needs.

[0039] The lifting rod 7 is threadedly connected to the handle 1. When the lifting rod 7 is rotated, it moves axially up and down within the handle 1 according to the transmission principle of the thread. Since the sealing plug 10 is fixed to the lower end of the lifting rod 7 and in close contact with the inner wall of the air chamber 11, the movement of the lifting rod 7 causes the sealing plug 10 to move as well. The overall center of gravity of the device changes with the position of the sealing plug 10 and the lifting rod 7. For example, when the sealing plug 10 moves upward, the air mass in the upper part of the air chamber 11 increases, and the center of gravity of the device moves upward; conversely, it moves downward. In this way, users can flexibly adjust the center of gravity of the device according to actual operating needs, improving the convenience and accuracy of operation.

[0040] The air chamber 11, the air hole 13 on the connecting cylinder 12, and the external airbag 8 form a connected gas channel. When the lifting rod 7 is rotated, causing the sealing plug 10 to be squeezed downwards within the air chamber 11, the gas inside the air chamber 11 is pressurized. According to the principle of gas pressure transmission, in a sealed container, the pressure applied to a stationary liquid or gas can be transmitted in all directions without changing magnitude. The compressed gas in the air chamber 11 is transmitted to the airbag 8 through the air hole 13, increasing the gas pressure inside the airbag 8, thereby causing the airbag 8 to inflate. After the airbag 8 inflates, it increases the contact area with the fingers, dispersing the pressure of the fingers pressing down, thus buffering and protecting the fingers, while also improving the stability and comfort of the grip.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
