Technical Field
The present invention relates to an electrosurgical instrument, in particular a surgical instrument for tissue ablation, cutting and fusion for use in surgery.
Background
In surgical operation, ablation, cutting and fusion of tissues are very important tissue treatment processes, and in the currently commonly used tissue ablation, cutting and fusion technologies, an electrically heated tissue ablation method is one of the important technologies, and the ablation, cutting and fusion processes of the tissues are realized by heating the tissues to cause aggregation and modification of proteins. Therefore, in the electrically heated tissue ablation method, the core is how to ensure rapid aggregation of proteins and rapidly raise their temperature. In human tissue, there are, in addition to proteins, a large number of liquid substances, such as blood, interstitial fluid, etc., the presence of which interferes significantly with the aggregation of proteins and the warming of the proteins.
In the prior art, a heating device is usually added to the end of a conventional surgical instrument, such as a surgical forceps, a surgical nickel instrument, etc., and the working surfaces of the instruments are usually in plane contact, and a large pressure is required to be applied to close the forceps head during the heating process so as to ensure that protein in the working area is agglutinated and modified. The operation process is inconvenient, and the ablation, cutting and fusion effects are not good because the interference of liquid substances on the aggregation and temperature rise of the protein cannot be eliminated.
Accordingly, there is a need for improvements in prior art tissue ablation, cutting and fusion systems, and in particular for further improvements in the working portion thereof.
