Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a structure-reinforced ultrasonic emulsification needle sleeve. Background Art

[0002] In ophthalmic surgeries, especially in the ultrasonic emulsification treatment of cataracts, the ultrasonic emulsification needle, as the core tool, its performance directly affects the success of the surgery. However, a technical challenge that cannot be ignored is that when the ultrasonic emulsification needle vibrates at high speed to emulsify and aspirate cataract tissue, extremely high heat is generated. If these heats cannot be dissipated in a timely and effective manner, it will not only cause the ultrasonic emulsification needle to overheat and be damaged, affecting its service life and surgical effect, but more seriously, it may transfer heat to the eye tissue through direct contact, causing burns to the patient's wound, increasing the surgical risk and the difficulty of postoperative recovery.

[0003] Currently, the ultrasonic emulsification needle sleeves widely used in the market, although designed to protect the ultrasonic needle and assist in heat dissipation, their structural limitations are becoming increasingly prominent. Specifically, as Figures 1 to 3 shown, the existing sleeves generally adopt an ultra-thin design, and the wall thickness a of the sleeve 2 mostly remains around 0.15 mm, as light as a cicada's wing but extremely fragile. During the operation, the emulsification needle 4 is immersed in the liquid flowing in the cooling cavity 5 to cool the emulsification needle 4. Such a thin sleeve is extremely vulnerable to external forces and will shift to one side of the emulsification needle 4, showing an eccentric phenomenon (as Figure 4 shown), and even problems such as breakage, collapse, stretching deformation or twisting may occur. These problems not only weaken the protection of the sleeve for the ultrasonic needle, making it unable to effectively isolate heat, but may also hinder the smooth flow of the coolant due to structural deformation, further weakening the cooling effect and unable to fully meet the high requirements of the operation for temperature control. During high-speed ultrasonic emulsification, the generated heat accumulates rapidly, and the sleeve cannot provide sufficient heat dissipation channels or surface area, resulting in the heat not being dissipated in a timely manner, further exacerbating the heat risk of the ultrasonic needle and the surgical wound.

[0004] Therefore, the inventor is committed to designing an ultrasonic emulsification needle sleeve to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a structure-reinforced ultrasonic emulsification needle sleeve, which can not only effectively prevent the sleeve from breaking, collapsing, stretching and twisting during the operation, ensure the stable protection of the ultrasonic emulsification needle, but also significantly improve the water circulation effect and cooling performance of the sleeve.

[0027] The following combines the drawings to specifically clarify the implementation manner of the present invention. The drawings are only for reference and illustration, and do not constitute a limitation on the scope of patent protection of the present invention.

[0028] Refer to Figures 5 to 7 , a structure-enhanced phacoemulsification needle sleeve, comprising a sleeve body 1. One end of the sleeve body 1 extends axially outward to form a tubular cannula 2. A plurality of reinforcing ribs 3 are arranged at intervals on the inner wall of the cannula 2. Each reinforcing rib 3 is strip-shaped and arranged along the axial direction of the cannula 2. The surface of one side of each reinforcing rib 3 facing the center of the cannula 2 is concave to form an arc.

[0029] Refer to Figure 5 , the outer diameter of the sleeve body 1 is greater than the outer diameter of the cannula 2. The cannula 2 and the sleeve body 1 are integrally formed. The wall thickness of the sleeve body 1 is greater than the wall thickness of the cannula 2. An internal thread 11 is provided on the inner wall of the end of the sleeve body 1 far from the cannula 2. A circular positioning table 12 is provided on the inner wall of the sleeve body 1. The positioning table 12 is located beside the internal thread 11. One end of the sleeve body 1 close to the cannula 2 is conical and forms a conical surface. A circle of bosses 13 is provided on this conical surface.

[0030] Refer toFigure 6 and Figure 7 At the end of the sleeve 2, there is a conical nozzle 21. The height b of each reinforcing rib 3 is 0.1 mm. The arc-shaped concave surfaces of all the reinforcing ribs 3 are arranged around the central axis of the sleeve 2. All the reinforcing ribs 3 are integrally formed with the sleeve 2. Preferably, the number of the reinforcing ribs 3 of the present utility model is four, and the four reinforcing ribs 3 are equidistantly arranged on the inner wall of the sleeve 2.

[0031] Referring to Figure 7 , when the emulsification needle 4 is located in the cooling cavity 5 of the cuff, since the arc-shaped concave surfaces of the four reinforcing ribs 3 are arranged around the central axis of the sleeve 2, the arc-shaped concave surfaces of the four reinforcing ribs 3 can match the outer wall of the emulsification needle 4, preventing the cuff from being eccentric.

[0032] The structure-strengthened ultrasonic emulsification needle cuff of the present utility model has the following beneficial technical effects:

[0033] (1). By arranging the reinforcing ribs 3 on the inner wall of the sleeve 2, the present utility model enhances the strength of the cuff, making the cuff not easily distorted or collapsed, with good cooling effect. The perfusion cuff surrounds the emulsification needle 4, and the needle tip of the emulsification needle 4 is immersed in the flowing liquid to cool the emulsification needle 4 and take away all the heat generated during the vibration of the emulsification needle 4;

[0034] (2). The emulsification needle 4 is farther away from the wound part, safer, and will not cause burns to the wound;

[0035] (3). The surgical environment has a low temperature and less heat, which is more conducive to the patient's recovery;

[0036] (4). The water flow is restricted and there is no turbulence, making the operation easier and safer;

[0037] (5). The patient recovers quickly and the surgical effect is good.

[0038] (6). The installation of the cuff of the emulsification needle 4 is simpler, easier, convenient, time-saving, and not easily damaged.

[0039] On the basis of maintaining a certain softness and biocompatibility, the structure-strengthened ultrasonic emulsification needle cuff of the present utility model significantly enhances its strength and stability through an innovative structural design. Specifically, the present utility model arranges a plurality of strip-shaped reinforcing ribs 3 on the inner wall of the sleeve 2 of the cuff. These reinforcing ribs 3 not only are arranged along the axial direction of the sleeve 2 to increase its longitudinal strength, but also optimize the water flow channel and cooling effect through the concave arc design facing the center of the sleeve 2.

[0040] The structure-reinforced ultrasonic emulsification needle sleeve of the present utility model can not only effectively prevent the sleeve from being broken, collapsed, pulled and twisted during the operation, ensuring stable protection of the ultrasonic needle, but also significantly improve the water circulation effect and cooling performance of the sleeve by increasing the heat dissipation area and optimizing the water flow path. During ultrasonic emulsification, the cooling water can flow more smoothly through the inside of the sleeve, taking away more heat, thereby effectively reducing the temperatures of the ultrasonic needle and the surgical wound and ensuring the safety of the operation and the comfort of the patient.

[0041] In summary, the structure-reinforced ultrasonic emulsification needle sleeve proposed in this patent provides a safer, more efficient and reliable solution for ultrasonic emulsification surgery while solving the problems of the prior art.

[0042] The above-disclosed are only the preferred embodiments of the present utility model, and the scope of the patent protection of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model.
