Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to an injection and suction handle cover cap for polishing the posterior capsule in cataract phacoemulsification surgery. Background Art

[0002] Cataract refers to a disease caused by protein denaturation in the lens due to various reasons such as aging, heredity, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., resulting in opacity. Currently, the only effective way to treat cataracts is to restore visual function through surgery. Posterior capsule opacity is the most common complication of cataract surgery. Posterior capsule opacity is one of the causes of secondary cataract formation, posterior capsule organization and deformation, and lens displacement, which seriously affects the patient's postoperative visual quality.

[0003] The existing injection and suction handle uses an emulsifier to make the turbid emulsion into chyle, and then uses a suction system to perform negative pressure extraction. However, in cases where some chyle attachments are severely attached, it is necessary to increase the negative pressure for extraction, and excessive negative pressure will cause the capsule membrane to rupture due to adsorption. In addition, since the existing handle is made of a smooth cylindrical material, hand fatigue and sweating will occur after long-term use, which will result in insufficient grip on the handle. Ultrasonic emulsification surgery is a delicate surgery that requires stable control by the operator.

[0004] In view of the above problems, a suction and injection handle cap for polishing the posterior capsule in phacoemulsification surgery for cataract is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an injection and suction handle cap for polishing the posterior capsule in cataract phacoemulsification surgery, which solves the problem that the commonly used injection and suction handle in the background technology adsorbs too much on the capsule and causes rupture, thereby increasing the safety of the surgery.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an injection and suction handle cap for polishing the posterior capsule during cataract phacoemulsification surgery, comprising a body; a handle, detachably connected to the body; an injection needle, fixedly connected to the handle and located inside the body; an injection and suction inlet, located at the top of the body; an injection inlet, located on the outer side wall of the body; a cleaning device, located inside the body; the cleaning device comprises a cleaning brush, a cleaning seat, an inflatable airbag, an trachea and a push column, the outer side wall of the body is provided with a cleaning groove, the interior of the cleaning groove is slidably connected with a cleaning seat, the outer side wall of the cleaning seat is fixedly connected with a cleaning brush, the interior of the cleaning groove is fixed with an inflatable airbag, one end of the inflatable airbag is fixedly connected with the trachea, the other end of the trachea is fixedly connected with a push column, the top of the push column is provided with a connecting groove, the interior of the connecting groove is rotatably connected with a connecting rod, and the connecting rod is rotatably connected to the cleaning seat.

[0007] As a further description of the above technical solution: an injection suction inlet is provided at the front section of the main body, and the injection suction inlet corresponds to the position of the injection suction tube of the handle.

[0008] As a further description of the above technical solution: an outer side wall of the body is provided with a filling port, and the filling port corresponds to the position of the water outlet of the handle.

[0009] As a further description of the above technical solution: the outer side wall of the handle is fixedly connected with an anti-skid pad, the outer side wall of the anti-skid pad is fixedly connected with a finger ring, and the finger ring is composed of a child Velcro and a mother Velcro.

[0010] As a further description of the above technical solution: a button is fixedly connected to the surface of the handle, a blower is fixedly connected to the inside of the body, and the button is connected to the blower signal.

[0011] As a further description of the above technical solution: the output end of the blower is connected to the inflatable airbag.

[0012] As a further description of the above technical solution: the injection needle is a bendable needle with a maximum bending angle of 135°.

[0013] As a further description of the above technical solution: the rear end of the handle is fixedly connected with an emulsifier.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention provides an injection and suction handle cap for polishing the posterior capsule in cataract phacoemulsification surgery. The cap body is detachably connected to the handle to avoid hard damage to the eye caused by metal materials. The attachments and chyle are scraped and cleaned by a cleaning device, thereby avoiding the situation in traditional surgery where the attachments are extracted by an enhanced negative pressure system and the capsule is ruptured due to excessive negative pressure, thereby increasing the safety performance of the surgery.

[0016] 2. The present invention provides an injection and suction handle cap for polishing the posterior capsule during cataract phacoemulsification surgery. The anti-skid pad is fixedly connected to the surface of the handle to increase the friction between the user and the handle.
