Supersonic wave device used for improving acute wound debridement efficiency

Abstract

The invention relates to a supersonic wave device used for improving acute wound debridement efficiency. The supersonic wave device comprises a host computer (16), a pump (12), a supersonic wave probe (1), a probe front end face (2), a probe front end face side face (3) and an inner probe through hole (4). The supersonic wave device is characterized in that the probe front end face side face (3) is provided with multiple tooth type cones (5), and front side faces of the tooth type cones are processed to be front inclination angles. Compared with the prior art, the mechanical fragmentation effect of a debridement cutter is fully performed, and wound debridement efficiency is greatly improved.

Description

technical field [0001] The invention relates to an ultrasonic device for improving the debridement efficiency of acute wounds, belonging to the field of ultrasonic medical equipment. Background technique [0002] The effective care and rapid healing of wounds has always been a difficult problem in the world's medical community. The global annual medical expenses for wound care and infection total more than 10 billion US dollars. Acute wounds, such as wounds caused by wars, natural disasters, car accidents, fires and other accidents, often retain a lot of foreign matter. If the disinfection is not cleaned up in time, it will cause ulceration and scabbing of related tissues. The treatment of acute wounds by medical staff is often divided into two steps, 1. removal of foreign bodies in the wound, festering, scab and necrotic tissue; 2. inactivation of bacteria in the wound. For the second step, those skilled in the art usually use an ultrasonic debridement device, in which the...

Problems solved by technology

In this patent, the sides of the front end face of the ultrasonic probe are knurled (see figure 2 ), the description of "knurling" in the patent is: engrave some parallel grooves on the side of the front face of the ultrasonic probe, and the groove depth is less than 0.5 mm. The friction between the side of the front end of the probe and the foreign matter or necrotic tissue on the patient's wound is used to effectively remove the patient's wound, but the parallel grooves described in the above patent are generally very shallow, so the formed friction is limited Yes, it is not very helpful to improve the efficiency of wound debridement. In addition, these grooves will affect the surface material structure of the front side of the ultrasonic probe. Ultrasonic probes are generally made of titanium alloy materials. Under the impetus of the ultrasonic probe, it reciprocates along the axial direction of the ultrasonic probe. The vibration frequency is generally 25-40KHz, and the vibration amplitude is generally 150-200 microns. , Grooves or even scratches on the surface of titanium alloy materials will cause cracks on the surface of titanium alloy materials, and these cracks will gradually extend to the deep layer of the material, eventually causing the front end of the ultrasonic probe to break, greatly reducing its service life
