Description
Technical field
The present invention relates to a kind of raising acute wounds debridement efficiency ultrasonic unit, belong to ultrasonic medical equipment field.
Background technology
Effective nursing of wound and quickly-healing are difficult problems for World Medical circle always, and the whole world adds up to more than 10,000,000,000 dollars for the medical expense of wound care and infection every year.Acute wounds, as the wound that the accidents such as war, natural disaster, traffic accident, fire cause, often retains a lot of foreign body, if sterilization, cleaning not in time, can cause festering of linked groups, incrustation etc.Medical personnel, for the process of acute wounds, are often divided into two steps, and the foreign body 1. in pair wound, festers, the removing of the tissue that incrustation is downright bad; 2. the deactivation of the antibacterial in pair wound.For second step, those skilled in the art adopt ultrasonic debridement device usually, ultrasound probe wherein can by interacting with the medicinal liquid on wound, produce cavitation effect, thus make the membranolysis of antibacterial, cause bacteria inactivation, but for the 1st step, prior art is often difficult to reach desirable effect.In addition, the ultrasonic debridement equipment of prior art is insufficient to utilizing of ultrasonic mechanical disintegration effect, and the surface of these ultrasonic debridement devices is all smooth, does not have mechanical disintegration effect to the slough of wound.
US Patent No. 7025735 and US6916296 disclose a kind of device clearing up wound, this device is cleared up acute wounds by the ultrasound probe of a hollow, medicinal liquid can arrive the wound location of patient by the through hole in the middle of probe, under the front end ultrasonic transducer in a device of this ultrasound probe promotes, do the reciprocating vibration along probe axial direction, frequency of vibration is generally 23-30KHz, Oscillation Amplitude is generally 250-350 micron, the side of such probe front end will produce phase mutual friction with the tissue on the wound of patient, after rubbing action a period of time, foreign body on patient wound, the slough festering and form a scab will come off, reach the object of cleaning wound, but the side of ultrasonic probe front end is all smooth in the device announced in such as US7025735 and US6916296, so foreign body on this probe and patient wound or the frictional force between slough just very little, cause its clinical debridement effect limited (see Fig. 1), the efficiency of cleaning wound is lower, extend the treatment time of patient, add the misery in patient treatment procedure.
For above-mentioned defect, just there are some improvement for ultrasonic probe in prior art, such as US Patent No. 2008/0058775 proposes a kind of ultrasonic probe for acute wounds process of improvement.The side of the front end face of ultrasonic probe all adds annular knurl (see Fig. 2) in that patent, the description of described patent to " annular knurl " is: in the side of the front end face of ultrasound probe, engrave the groove that some are parallel, gash depth is less than 0.5 millimeter, frictional force during by arranging groove to increase cleaning acute wounds between the side of ultrasonic probe front end face and the upper foreign body of patient wound or slough, to reach the object effectively removing patient wound, but the parallel groove described in above-mentioned patent is in general very shallow, so the frictional force formed is limited, help little for raising wound debridement efficiency, in addition, these grooves can impact the surface material structure of ultrasound probe front end face side, ultrasound probe is generally made up of titanium alloy material, operationally, ultrasound probe is under the promotion of ultrasonic transducer, axis direction along ultrasound probe does reciprocating vibration, frequency of vibration is generally 25-40KHz, Oscillation Amplitude is generally 150-200 micron, as the titanium alloy material that ultrasound probe adopts, when being under work fatigue state, the groove even cut on titanium alloy material surface, capital causes titanium alloy material surface to crack, these crackles can expand to material deep layer gradually, ultrasound probe front end is finally caused to be ruptured, greatly reduce its service life.
Summary of the invention
To be correlated with the above-mentioned defect of apparatus for debridement to overcome prior art, the present invention has carried out relevant improvement to ultrasonic debridement device, in the side of ultrasound probe front end, process one group of small profile of tooth cone, these cones are distributed on the side of ultrasound probe front end, and it is highly 0.5-1 millimeter.In general, these profile of tooth sawtooth can select pyramid type, triangular pyramid type, rectangular pyramid etc. (as Fig. 6), in addition, these profile of tooth cones are alternating expression (as Figure 13) in the distribution of ultrasonic probe front end face side, the present invention is in the top rake (as Figure 16) of each flute profile cone, specifically, technical problem to be solved by this invention is to provide a kind of improved ultrasonic debridement therapeutic instrument, comprise ultrasound probe, probe front end face, probe front end face side, probe inner via hole, be characterised in that: described probe front end face side arranges several profile of tooth cones, the leading flank of described profile of tooth cone is processed to a top rake.As a modification of the present invention, described profile of tooth cone is pyramid type.Improve as another kind of the present invention, described profile of tooth cone is triangular pyramid type.Improve as another kind of the present invention, described profile of tooth cone is rectangular pyramid.Improve as another kind of the present invention, described profile of tooth cone distributes at the alternating expression that is distributed as of ultrasonic probe front end face side.By Curve guide impeller of the present invention, avoid prior art and cause the defect reduced service life of popping one's head in owing to arranging groove, the tapered sawtooth of the alternating expression arrangement of the application's design is conducive to clearing up the unobstructed discharge of residue of foreign body in patient wound or slough, process an inclination angle in the front end of each profile of tooth cone, be conducive to these profile of tooth cones and effectively thrust in the course of the work in foreign body in patient wound or slough.
