Visual ultrasound scalpel for hepatobiliary surgery and remote ultrasound surgical system

Abstract

The invention discloses a visual ultrasound scalpel for hepatobiliary surgery and a remote ultrasound surgical system. The visual ultrasound scalpel for hepatobiliary surgery comprises a knife tube and a handle. The handle comprises a body and a grip. The knife tube is inserted in the front end of the device body. The visual ultrasound scalpel for hepatobiliary surgery also includes an ultrasonictransducer, a horn, a first connector, a lens tube holder, a first shock absorbing mechanism and a second shock absorbing mechanism, arranged in the device body, and a endoscope tube arranged in the knife tube and the body. The ultrasonic transducer is connected with an amplitude horn, wherein the amplitude horn is fixedly connected with a knife tube through a first connecting piece; the endoscopetube is arranged in the knife tube and is not in contact with the inn wall of the knife tube, and the rear end is fixed on the lens tube holder, and the endoscope tube is used for collecting opticalimages; the first shock absorbing mechanism is fixed on the speculum tube for reducing vibration transmitted from the knife tube to the speculum tube; and the second shock absorbing mechanism is fixedon the lens tube holder for reducing vibration transmitted from the body to the lens tube holder. The invention can realize the visualization function of the ultrasonic knife and the remote visualization function of the ultrasonic operation system.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a visible ultrasonic knife for hepatobiliary surgery and a remote ultrasonic surgery system. Background technique [0002] Ultrasonic (suction) knife is a special hollow knife widely used in hepatobiliary surgery. Its working principle is mainly based on the cavitation effect of ultrasound, that is, high-frequency energy is applied to the knife to make it vibrate at high frequency, and the knife then acts on the liver or gallbladder. The lesion tissue (such as tumors, etc.), causing the lesion tissue fragmentation, and then sucking out the residual tissue through negative pressure, has the advantages of less damage, less bleeding, and faster recovery. [0003] Due to the dense blood vessels around the liver and gallbladder, even a small operation error can easily cause massive bleeding. Therefore, it is generally used with a medical endoscope to ensure a clear surgical field of vie...

Problems solved by technology

[0004] However, since the tool of the ultrasonic (suction) knife is in a state of high-frequency oscillation when it is working, if a medical endoscope is directly integrated on the tool, the medical endoscope will also vibrate at high frequency accordingly, making the imaging picture high-frequency Oscillation makes the surgical field of view extremely unclear, which directly affects the safety of the operation, and the medical endoscope is also easily damaged

Therefore up to now, still do not have an ultrasonic (suction) knife to be integrated with medical endoscope, all do not have visual function

[0005] In addition, with the continuous development of intelligent technology and Internet technology, the remote visualization of surgical operations has attracted more and more attention. Remote visualization can not only realize the viewing of surgical images in places far away from the operating room (such as remote viewing of surgical images by medical staff in different places through smart phones ), and can also collect relevant image big data for analysis and research (such as the regional medical analysis of liver cancer based on the image big data of liver cancer surgery in medical schools), but the current ultrasonic surgery system does not yet support remote visualization
