Abstract
This utility model discloses a waterproof structure for the wiring of an ultrasonic surgical instrument transducer, comprising one or more wires and a housing for connecting the wires. The wires are wrapped with a smooth insulating layer, and a rigid first waterproof block is provided outside the insulating layer. The first waterproof block is seamlessly integrated with the insulating layer. Because the first waterproof block connected to the wires is rigid and seamlessly integrated with the wires, when the wires undergo an airtightness test, the rigid material of the first waterproof block prevents gas and liquid from passing through the gap between the first waterproof block and the wires due to the poor contractility of the wires inserted within it. This enhances the waterproof and airtight effect of the structure.
