Embodiment 1

[0033] See figure 1 As well as figure 2 The present invention provides an ultrasonic meter dissolving around the prosthesis after the joint replacement, mainly processor 1. Ultrasonic generator 2. Output probe 3. Display screen 4. Operation knob 5, power supply 6, ultrasonic cupboard, ultrasonic CCPCThe composition of 10, the front of the shell 10 is equipped with an LED display 4. Operation knob 5, USB communication interface 13, probe connection end 14, probe stand on the sideInside, processor 1. Ultrasonic generator 2. Display 4 and power 6 series, ultrasonic generator 2 connect the output probe 3 through the output end of the power modulation circuit.

[0034] See Figure 5 Output probe 3 consists of converter 12, ring -shaped LED alert indicator 7, Diversion 8 and base 9, output probe 3 is L -shaped, structured seal waterproof, the head is cylindrical, and the converter 12 is fixed to the probe through the thread 12 to the probe.The base 9 near the head 9, the lead 8 is connec...

Embodiment 2

[0043] Example 2: See Figure 6 As well as Figure 7 Output probe 3 is also equipped with underwater treatment rack 15 with a special shape. The treatment rack 15 has a groove with ultrasonic probe 3 to play a stable probe.Gently squeeze the ultrasonic probe 3 into the corresponding groove of the therapy rack, bind it to the body surface therapy site together with the treatment rack, and combine the ultrasonic treatment at the same time, which can also help improve the efficacy.In the limbs, ultrasonic therapy combined with spa play a fixed probe, and the surface of the probe is close to the skin to ensure the curative effect.

Embodiment 3

[0044] Example 3: See Figure 8 The output probe of this embodiment is a flat cylindrical type 16, without handle, and matched with a thick -quality fixed zone 17. When using it, the probe can be fixed on the skin surface with the assistance of the fixed belt.Senior citizens.The thick fixed band is fixed with nylon buckle, so that it can adapt to the thickness of different sizes of different people and different therapeutic parts (such as the upper or lower limbs). The same user can also adjust to the comfortable state at will.

Abstract

The invention provides an ultrasonic apparatus for preventing osteolysis from appearing around a prosthesis after joint replacement. The ultrasonic apparatus is mainly composed of a processor, an ultrasonic generator, an output probe, a display screen, an operation rotary knob, a power supply and an ultrasonic apparatus shell, wherein the processor and the ultrasonic generator are located in the ultrasonic apparatus shell, the processor, the ultrasonic generator and the display screen are connected with the power supply in series, and the ultrasonic generator is connected with the output probe. The ultrasonic apparatus is reasonable in design and convenient to carry, the ultrasonic frequency, the strength, the duty ratio, the working hour span and the area of the output probe can all be adjusted and matched with data bases composed of different parameters combinations, different types of parameter setting can be arranged as required, probes in different sizes can be adopted as required, corresponding low-energy ultrasonic waves are transmitted to the area around the prosthesis, therefore, the osteolysis is prevented from appearing around the prosthesis, reconstruction of bone trabeculas around the prosthesis is promoted, the bone mineral density around the prosthesis is improved, the service life of the prosthesis is prolonged, the ultrasonic apparatus is suitable for different people, no use contraindication exists, no invasive intervention occurs to a user, and the ultrasonic apparatus is relatively safe.

Description

Technical field [0001] The present invention is a medical device, which involves a ultrasonic meter dissolving around the prosthesis after the replacement of arthric joint replacement. Background technique [0002] Artificial joint replacement is one of the revolutionary progress in the 20th century orthopedic field. However, with the increase in the number of joint replacement and the extension of time, the problem of late prosthesis loosening is increasingly prominent.According to statistics, after 15 to 20 years in the prosthesis replacement, 10-15%of the arthropic joints will fail with prosthesis. The main reason for the failure of the prosthesis is that the arthropod is sterile and loosen, and the false granules induced.Bone dissolving around the body is the most important factor that causes prosthesis to loosen.Sterile loosening arthropine is the most important complications that affect the long -term use of arthrops and the main causes of prosthetic failure and renovation....
