Ultrasound knife for ophthalmologic operation

Abstract

The invention discloses an ultrasound knife for an ophthalmologic operation. The ultrasound knife comprises an ultrasound knife instrument, a rotating support is installed at one corner of the top ofthe ultrasound knife instrument, a longitudinal telescopic rod is rotatably arranged on the ultrasound knife instrument through the rotating support, a transverse telescopic supporting rod is fixedlyconnected to the upper end of the longitudinal telescopic rod, a storage device is fixedly arranged at the end, away from the longitudinal telescopic supporting rod, of the transverse telescopic supporting rod and used for storing the head of the ultrasound knife, and a winding mechanism is fixedly arranged on the part, on one side of the storage device, of the telescopic supporting rod, and comprises a round bottom plate, a screw rod and a movable disc. The longitudinal telescopic supporting rod and the transverse telescopic supporting rod are arranged rotatably, in this way, during the operation, a connecting line of the head of the knife and the instrument is wired, the operation is conducted conveniently, meanwhile, the winding device can take up and pay off the wire, the length of thewire is determined according to the operation, during the operation, pulling and falling caused by the wire are voided, the convenience of the operation is improved, and the ultrasound knife is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an ultrasonic scalpel for ophthalmic surgery. Background technique [0002] The full name of ophthalmology is "eye disease specialist", which is a discipline that studies diseases that occur in the visual system, including the eyeball and its associated tissues. Ophthalmology generally studies vitreous, retinal diseases, optometry, glaucoma and optic neuropathy, cataract and other ophthalmic diseases. [0003] When performing ophthalmic surgery, the tool that is often used is the ultrasonic scalpel. The existing ultrasonic scalpel is very inconvenient to use and cannot meet the needs of use. Since ophthalmic surgery requires high surgical accuracy, the convenience of using the ultrasonic scalpel is very important. Currently, ultrasonic scalpels When the knife is in use, because the knife head is often connected to the main body of the instrument through a cable, the c...

Problems solved by technology

[0003] When performing ophthalmic surgery, the tool that is often used is the ultrasonic scalpel. The existing ultrasonic scalpel is very inconvenient to use and cannot meet the needs of use. Since ophthalmic surgery requires high surgical precision, the convenience of using the ultrasonic scalpel is very important. At present, the ultrasonic scalpel When the knife is in use, because the knife head is often connected to the main body of the instrument through a cable, the cable is dragged around during the operation, which not only makes the operation inconvenient, but also easily causes surgical accidents due to the dragging of the cable. Deviation, affecting the surgical effect, for this reason we designed an ophthalmic surgical ultrasonic knife to solve the above problems
