Embodiment 1

[0029] Embodiment 1, an anti-adhesion surgical equipment, such as an ultrasonic scalpel, includes an ultrasonic generator, a hand-held control unit and a pincer-shaped working head divided into an upper jaw with parallel teeth and a square columnar lower jaw, and can also be equipped with an endoscope at the same time A lighting and imaging device, characterized in that the surface of the working head contains a layer of perfluorocarbon compound, high-purity graphite target or cathode, carbon nanotubes and silicon deposited with a thickness of nanometer or micrometer fluoride-doped silicon diamond film. The fluorinated silicon-doped diamond-like carbon film contains less than 50 atomic percent of fluorine.

[0030]Preferably, the ion beam assisted magnetic filtered cathodic arc plasma deposition method is used to manufacture the working head of the surgical device with fluorinated silicon-doped diamond-like film of the present invention. First, the upper jaw with parallel tee...

Abstract

The invention discloses an anti-adhesion surgical device which comprises a power generator, a handheld control unit and a working head. The anti-adhesion surgical device is characterized in that the surface or a part of the working head is provided with at least one layer of nano or micron fluorinated diamond-like carbon film, fluorinated silicon-doped diamond-like carbon film, fluorinated silicon doped diamond-like film, fluorinated silicon and boron doped diamond-like film or fluorinated silicon, boron and nitrogen doped diamond-like film deposited by using a perfluocarbon compound, a high purity graphite target or a cathode, a carbon nano tube and / or semiconductor materials including materials which can form n-type or p-type semiconductors together with silicon. The working head of the surgical device provided by the invention has extremely strong hydrophobicity and can still have low friction coefficient and self-lubricating property under laparoscopic surgery environment with high relative humidity, and the cutting and anti-adhesion capabilities are enhanced.

Description

technical field [0001] The invention relates to a surgical device, in particular to a working head of an anti-adhesion surgical device, and a related manufacturing method and device. Background technique [0002] There are many types of existing surgical instruments or equipment, including electric non-invasive or minimally invasive surgical equipment, and their working energy includes ultrasound, sonar, microwave, magnetic force, cryoablation, radio frequency including high frequency and ultrahigh frequency, photodynamic force, laser , radiation, electric cauterization, plasma including cold plasma, gas including argon, vacuum, endoscopic lighting or imaging, etc. The working head and its processing technology have a great influence on the performance of the equipment, and even directly determine the success or failure of the operation and the safety of the patient's life. Outdated surface treatment technology leads to low energy conversion efficiency. In surgical practic...
