Embodiment Construction

[0042] Such as Figure 1-10 Shown is an ultrasonic knife for ophthalmic surgery, including a handle 1 and a knife head.

[0043] Such as figure 1 and 2 The handle 1 shown has a housing 1.1 in which a power supply and an ultrasonic generator 1.2 are housed. The housing 1.1 is provided with a trigger button 1.3 for starting and stopping the work of the ultrasonic generating device 1.2, and a display screen 1.4 for displaying the working state of the power supply and the working state of the ultrasonic generating device 1.2 (the trigger button 1.3 and the display screen 1.4 It is a subsidiary structure of circuit board 1.2.3). The ultrasonic generating device 1.2 includes an ultrasonic generator (power supply and circuit board 1.2.3), an ultrasonic transducer (a piezoelectric ceramic element 1.2.5, masses 1.2.6 and 1.2.7 and a variable amplitude 1.2.8 mechanism) . The head end of the housing 1.1 is provided with an output end of an ultrasonic generator (head end with variabl...

Abstract

The invention discloses an ophthalmic operation ultrasonic scalpel which comprises a handle and a tool bit. The handle is provided with a shell, a power source and an ultrasonic generating device arearranged inside the shell, and the head end of the shell is provided with the output end of the ultrasonic generating device; the tool bit is provided with a tool bit body, the tool bit body is sequentially provided with a connecting part, a limiting installing part and a blade part from bottom to top, the connecting part is used for being detachably connected with the output end of the ultrasonicgenerating device, the limiting installing part is used for installing a limiting mechanism to ensure the cutting depth, and the blade part is used for cutting. The purpose that a blade can instantlycut corneas downwards is achieved, and the scalpel can be used for keratoplasty and corneal limbus dissociation dissection.

Description

technical field [0001] The invention relates to an ultrasonic cutting device, in particular to an ultrasonic keratome for ophthalmic surgery. Background technique [0002] The cornea is the thin, transparent tissue at the front of the eyeball. Trauma infection often causes corneal transparency to decrease. [0003] Corneal transplantation is an important surgical method for treating corneal diseases. It is a surgical method to replace the diseased corneal part with transparent normal corneal tissue. Corneal trephine is a surgical instrument that must be used in corneal transplantation, which can ensure a regular cutting range and facilitate surgical suturing. Traditional corneal trephine cuts by rotating the blade, which inevitably causes tissue torsion and occasional trephine displacement during the cutting process, resulting in irregular cuts. [0004] Limbal releasing incision (LRI) is a method of correcting astigmatism by making single or paired loosening corneal inci...
