Electric sound wave pulse scrubbing device for artificial joint infection revision

Abstract

The invention discloses an electric sound wave pulse scrubbing device for artificial joint infection revision. The device comprises a high-frequency sound wave vibration scrubbing structure, a positive and negative pressure alternate pulse flushing and sucking structure, a water inlet and sucking structure, a power supply control and power supply structure, a first shell and a second shell; the first shell and the second shell are buckled and connected; the high-frequency sound wave vibration scrubbing structure, the positive and negative pressure alternate pulse flushing and sucking structure, the water inlet and sucking structure, and the power supply control and power supply structure are mounted in an inner cavity formed after the first shell and the second shell are buckled; and the high-frequency sound wave vibration scrubbing structure comprises a magnetic suspension high-frequency vibration motor, connecting rods and brush heads, and the magnetic suspension high-frequency vibration motor is clamped to the position, close to the center of the inner side of a muzzle, of the first shell. The device can effectively remove bacterial biofilms and other infected tissues infectingthe surface of an artificial joint, significantly improve the flushing efficiency, improve the flushing effect, shorten the operation time and improve the operation success rate.

Description

technical field

[0001] The invention relates to the field of medical equipment, in particular to an electric sonic pulse scrubbing device for artificial joint infection revision. Background technique

[0002] In the surgical treatment of infection after artificial joint replacement, the key to the success of the treatment is to completely remove the bacterial biofilm on the surface of the artificial joint prosthesis. This requires extensive and sufficient scrubbing of the surface of the artificial joint prosthesis and surrounding tissues to completely remove stubborn bacterial biofilms and minimize the chance of infection recurrence. At present, the method of scrubbing with a disinfecting brush is mostly used to remove bacterial biofilm, but there are defects such as too slow frequency of scrubbing, low scrubbing efficiency, and insufficient scrubbing, and at the same time, it is impossible to perform negative pressure flushing while scrubbing to effectively remove infected ...
