Description

Technical Field

[0001] The present application relates to the technical field of ophthalmic cataract phacoemulsification, and in particular to a disposable phacoemulsification needle infusion sleeve. Background Art

[0002] When factors such as aging, heredity, metabolic abnormalities, trauma, radiation, and poisoning cause lens opacity, blurred vision, astigmatism, diplopia, photophobia, and serious vision impairment, lens replacement surgery is required. Commonly used methods include phacoemulsification and laser emulsification. The needle of cataract phacoemulsification is a special tiny tool that uses ultrasonic energy to break down the lens into small pieces and suck them out.

[0003] In the prior art, a large amount of heat is generated when the ultrasonic emulsification needle is working. If it is not cooled in time, the ultrasonic needle will be directly burned. At the same time, a large amount of heat will also burn the wound in contact with the ultrasonic needle. For this reason, we propose a disposable ultrasonic emulsification needle perfusion sleeve to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that a large amount of heat will be generated when the ultrasonic emulsification needle is working. If it is not cooled in time, the ultrasonic needle will be directly burned; at the same time, a large amount of heat will also burn the wound in contact with the ultrasonic needle, and a disposable ultrasonic emulsification needle perfusion sleeve is proposed.

[0005] The present application provides a disposable phacoemulsification needle irrigation sleeve adopts the following technical solution:

[0006] A disposable phacoemulsification needle irrigation sleeve, comprising:

[0007] Main cuff;

[0008] The first sleeve is fixedly connected to the main sleeve. The main sleeve adopts a thickened design to improve the strength, is not easy to fall off, and is safe and reliable. The first sleeve adopts an ultra-thin design, which does not affect the vibration of the emulsification needle body and reduces the tension support on the wound of the emulsification needle body as much as possible;

[0009] A cavity is provided in the main sleeve and the first sleeve, and is filled with a coolant. The cavity is used to store as much coolant as possible to cool the emulsification needle body wrapped in the first sleeve and the main sleeve;

[0010] The emulsification needle body is connected to the main sleeve and the first sleeve. The main sleeve is provided with a U-shaped opening. The U-shaped opening design allows for easy installation. The inner wall of the U-shaped opening is provided with threads, which are used to tightly connect to the ultrasonic emulsification handle without falling off or leaking.

[0011] Furthermore, one end of the first sleeve is connected with a closing opening, which is used to contain the entire liquid. The first sleeve is provided with two symmetrical circular holes, which are used for cooling liquid to overflow from the front end to cool the surgical wound.

[0012] In summary, the present application includes at least one of the following beneficial technical effects:

[0013] 1. In this solution, the main sleeve and the first sleeve surround the emulsification needle body, and the emulsification needle body is immersed in the flowing liquid to cool the emulsification needle body and take away all the heat generated by the vibration of the emulsification needle body;

[0014] 2. In this solution, the emulsification needle body is isolated from the wound part by setting the first sleeve, and will not cause burns to the wound.

[0015] The utility model can cool the ultrasonic emulsification needle and effectively protect the wound during use, and the operating environment has a low temperature and less heat, which is more conducive to the patient's recovery. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1 and Figure 2 , a disposable phacoemulsification needle irrigation sleeve, comprising:

[0021] Main cuff 3;

[0022] The first sleeve 5 is fixedly connected to the main sleeve 3. The main sleeve 3 adopts a thickened design to improve the strength, is not easy to fall off, and is safe and reliable. The first sleeve 5 adopts an ultra-thin design, which does not affect the vibration of the emulsification needle body 8 and reduces the tension support on the wound of the emulsification needle body 8 as much as possible;

[0023] The cavity 4 is opened in the main sleeve 3 and the first sleeve 5, and the cavity 4 is filled with a coolant 9. The cavity 4 is used to store as much coolant 9 as possible to cool the emulsification needle body 8 wrapped in the first sleeve 5 and the main sleeve 3;

[0024] Emulsification needle body 8, emulsification needle body 8 is connected in the main sleeve 3 and the first sleeve 5, the main sleeve 3 is provided with a U-shaped opening 1, the design of the U-shaped opening 1 can be convenient for installation, the inner wall of the U-shaped opening 1 is provided with a thread 2, the thread 2 is used to be tightly connected to the ultrasonic emulsification handle, without falling off and leaking, one end of the first sleeve 5 is connected with a closing 7, the closing 7 is used to contain the entire liquid, the first sleeve 5 is provided with two symmetrical circular holes 6, the two circular holes 6 are used for cooling liquid 9 to overflow from the front end to cool the surgical wound.

[0025] The implementation principle of a disposable ultrasonic emulsification needle perfusion sleeve in the embodiment of the present application is as follows: when in use, when the cooling liquid 9 flows in the cavity 4 between the main sleeve 3, the first sleeve 5 and the emulsification needle body 8, the cooling liquid 9 takes away the heat generated by the vibration of the emulsification needle body 8, cools the emulsification needle body 8, and cools the surgical wound at the same time. The first sleeve 5 can isolate the emulsification needle body 8 from the wound part and will not cause burns to the wound, thereby effectively improving the surgical effect and being more conducive to the patient's recovery.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
