Angle-adjustable medical debridement water jet

Abstract

The invention belongs to the technical field of medical equipment, and in particular relates to an angle-adjustable medical debridement water jet. The water jet includes a connection handle, one end of the connection handle is fixedly connected to a fixing cylinder, the inner side of the fixing cylinder is fixedly connected to a limiting cylinder, one side of the limiting cylinder is fixedly connected with a spring, the inner side of the spring is provided with a connecting rod, and one side of the connecting rod is provided with limit insertion rods; and a rotating ring is rotatably connectedto the inner side of the fixing cylinder, and one end of the connecting rod is fixedly connected with a button; and a movable frame is arranged on the outer side of the fixing cylinder, and one sideof the movable frame is fixedly connected with a medical water jet. When the angle of the medical water jet is adjusted, the button is pressed, the connecting rod drives the limit insertion rods to separate from limiting teeth, then the movable frame can drive the medical water jet to move to facilitate adjusting the angle of the medical water jet, and after adjustment is completed, the limit insertion rods automatically reset under the action of the spring to facilitate fixing the rotating ring by using the limit insertion rods to prevent the medical water jet from being shaken.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an angle-adjustable medical debridement water knife. Background technique [0002] Medical waterjet is a new type of cutting process using water as the medium. It injects specially treated water into a high-pressure water booster system to rapidly pressurize the water, and then passes this high-pressure water through a large-diameter A small nozzle that jets out a jet of water with pressure and speed to cut tissue. The traditional scalpel has the following disadvantages: First, although the tissue can be removed quickly, it cannot remove the necrotic tissue in a precise and controllable manner. When encountering a wound with necrotic and active tissue, it is impossible to judge, and it can only be cut across the board, and multiple excision of the tissue cannot be avoided; The site is limited, and it needs to be expanded if necessary; the third is that excess...

Problems solved by technology

The traditional scalpel has the following disadvantages: First, although the tissue can be removed quickly, it cannot remove the necrotic tissue in a precise and controllable manner. When encountering a wound with necrotic and active tissue, it is impossible to judge, and it can only be cut across the board, and multiple excision of the tissue cannot be avoided; The site is limited, and it needs to be expanded if necessary; third, excessive excision of tissue will cause massive bleeding; fourth, it is not suitable for wound debridement of ischemic ulcer; therefore, a medical water knife is needed

[0003] The existing technology has the following problems: the water jet cannot be adjusted, and there are many inconveniences in the use of debridement, which will not only affect the use of doctors, but also cause secondary damage to patients
