Description
Technical Field
The invention relates to the technical field of medical instruments and equipment, in particular to an ultrasonic knife provided with a telescopic diagnosis sound head.
Background
High-energy focusing ultrasonic equipment, also called ultrasonic knife, is a surgical equipment which is being widely popularized. The ultrasonic wave is focused inside the affected part of the human body to generate local high energy by utilizing the good directivity and penetrability of the ultrasonic wave to the human body tissue, and the cavitation effect of the acoustic energy is utilized to be 'cooked', namely the coagulative necrotic affected part, thereby finally achieving the purpose of non-invasive surgery.
In order to achieve precise focusing, the surgical device generally needs to provide intra-operative image guidance and post-operative effect evaluation by using an ultrasonic guidance probe and an ultrasonic diagnostic device.
The guiding mode of embedding the ultrasonic diagnosis probe in the center of the high-energy focusing ultrasonic cutter head appears in the market at present, and the guiding mode is advanced. The ultrasonic probe of a standard ultrasonic diagnosis device is arranged in the center of a high-energy focusing ultrasonic tool bit, a water sac is placed at the front end of the ultrasonic probe for cooling and ultrasonic coupling, real-time image guidance can be provided for an ultrasonic scalpel surgeon through the set of ultrasonic diagnosis system before, during and after an ultrasonic scalpel operation, the ultrasonic guide probe at a higher-level point has a rotation function, and simple three-dimensional image acquisition can be realized.
But the current embedded ultrasound guide image also has some disadvantages:
1. a water sac exists between the guiding probe and the patient, and the inner membrane and the outer membrane of the water sac have certain thickness and larger acoustic impedance. Meanwhile, the inner membrane side is also filled with a coupling medium, so that the diagnosis sound head is coupled into the whole system, the method causes that media such as an inner membrane, an outer membrane, deionized water, a sound head coupling agent and the like are arranged between the diagnosis sound head of a patient, the sound media change more, the acoustic impedance of each medium is different, the differences can generate a plurality of reflection interfaces, the image is attenuated greatly, and meanwhile, the artifact of the ultrasonic image can be increased along with the increase of the refraction surface. Artifacts, attenuation and other factors lead to the blurring of images generated by the guided ultrasound or no longer have significance in postoperative evaluation of the operation effect. The influence on Doppler imaging, blood flow imaging and the like is particularly serious.
2. In practical applications, a doctor has to pause the operation for many times before or after the operation to obtain a high-quality evaluation image, and then uses an additional ultrasonic diagnostic device to evaluate the operation effect. The time for these evaluation procedures far exceeds the operation time, increasing the burden on the doctor and the patient.
3. The ultrasonic diagnosis has high sensitivity to echo, and the quantity and energy of an ultrasonic generator used for operation in the ultrasonic cutter head are far higher than those of a diagnostic ultrasonic probe. When the ultrasonic probe and the ultrasonic probe work simultaneously, the ultrasonic echo generated when the high-energy ultrasonic probe works greatly interferes the imaging signal of the ultrasound guided in the operation, and influences the image quality and the acquisition sensitivity. Meanwhile, the high energy of the ultrasonic tool bit can cause irreparable damage to the piezoelectric ceramics guiding the ultrasonic probe. These factors result in a high rate of damage to the probe guiding the ultrasound and a significant increase in attenuation of the sonotrode. The replacement of the guide probe is finished by a manufacturer, and the probe needs to be calibrated after the replacement, so that the cost is high, the maintenance time is long, and the clinical application is influenced.
