Problems solved by technology
In the process of tearing off the biofilm, the doctor's physiological hand tremors and unskilled surgical operations may increase the force between the instrument and the eye tissue, thereby causing unnecessary eye damage, which requires the design of a The micro-vibration module can generate micro-vibration to compensate the doctor's hand trembling, but the existing micro-vibration module for ophthalmic surgery is not perfect, such as: the range of vibration amplitude and frequency is not large enough, the processing accuracy is high, and the assembly is complicated. Complicated preparation, large quality and size, etc.

The invention discloses a micro-vibration operation module for ophthalmic surgeries. A surgical device is put at the top end of a movable platform, and a center column is fixedly connected with the bottom end of the movable platform; a mount hole is processed in the center of the movable platform and the center column; the bottom end of the center column is fixedly connected with a base; a mount interface is processed in the center of the base; one end of a first lower reed is fixedly connected with the upper end of one side of the base, a first lower piezoelectric fiber plate is adhered to the center of the first lower reed, and the other end of the first lower reed is connected with a first connection block; a first upper reed is connected with the top end of the first connection block;a first upper piezoelectric fiber plate is adhered to the center of the top of the first upper reed; and a first mass block is fixedly connected with the top of the other end of the first upper reed.According to the micro-vibration operation module for ophthalmic surgeries, the reeds are driven to bend to perform position correction by contraction of the piezoelectric fiber plates after electrification. The micro-vibration operation module is sufficient in vibration amplitude and frequency range, has the advantages of simple assembly and preparation, small mass and size and the like, and is anew-generation of micro-vibration operation module for ophthalmic surgeries.
Description
technical field [0001] The invention relates to the technical field of medical machinery, in particular to a micro-vibration operation module for ophthalmic surgery. Background technique [0002] In common ophthalmic operations, such as cataract capsulorhexis, retinal tearing, and glaucoma iridectomy, doctors need to tear a very thin layer of biofilm from the surface of the eye tissue. In the process of tearing off the biofilm, the doctor's physiological hand tremors and unskilled surgical operations may increase the force between the instrument and the eye tissue, thereby causing unnecessary eye damage, which requires the design of a The micro-vibration module can generate micro-vibration to compensate the doctor's hand trembling, but the existing micro-vibration module for ophthalmic surgery is not perfect, such as: the range of vibration amplitude and frequency is not large enough, the processing accuracy is high, and the assembly is complicated. The preparation is compl...
