A coupling means () serves for connecting a suction channel () of an electrosurgical instrument () to a vacuum source via a suction tubing () and/or for guiding an electrical cable (), that supplies electrical energy from an electrosurgical generator to the electrosurgical instrument (). The electrosurgical instrument () comprises a hollow elongated main body () having a first end () for securing a first means () for application of the electrical energy to a surgical site and an opposite second end (), which hollow elongated main body () has a switch means () to be operated by means of an associated actuator () to control application of the electrical energy to the surgical site. The coupling means () comprises at least a first coupling part (&#x2033;) for inserting between the second end () of the hollow elongated main body () and the suction tubing (), which first coupling part (&#x2033;) is configured to attach the suction tubing () in tandem with said hollow elongated main body () and/or to accommodate the electrical cable () exiting the hollow elongated main body () along the longitudinal axis of said first coupling part (&#x2033;). A kit including the coupling means and other components for an electrosurgical instrument is also disclosed.

Methods of manufacturing a length of a flexible polymeric medical tubing of the kind comprising a tubing member defining a lumen, which tubing member is surrounded by spiral convolutions along at least a part of the length of the proximal section and/or the distal section, and which medical tubing has a proximal convoluted section and a distal convoluted section, is disclosed, as well as medical tubings obtained by the methods and their uses. One method comprises the steps of providing a medical tubing wherein the proximal section and the distal section have substantially uniform initial pitch (P) between adjacent convolutions, and modifying the initial pitch (P) of at least a part of the proximal section by stretching at least a part of the proximal section to achieve a modified proximal section with a proximal pitch (P) between adjacent convolutions that is larger than the initial pitch (P) between adjacent convolutions. In another method the medical tubing is manufactured in a molding process. The so obtained medical tubing is particularly suited for use in open surgical procedures that requires suction and/or irrigation during use of an electrosurgical instrument.

An electrosurgical device for coagulating and for making incisions in or severing tissue such as blood vessels, the device comprising forceps jaws ( ) for immobilizing a tissue portion to be coagulated and incised, the forceps jaws ( ) being connected to means for applying an electrical tension between said forceps jaws for coagulating the tissue portion, the device further comprising a member ( ) for being displaced between said forceps jaws ( ) to incise a tissue portion held between the forceps jaws and coagulated thereby, the member ( ) being connected to means for applying an electrical voltage to said member for performing an incision in said tissue by means of said electrical voltage applied to said member ( ) the member ( ) preferably being blunt such that the incision substantially exclusively is achieved by means of the voltage applied to the member ( ). For preventing the generation of smoke through charring of the tissue portion, a tube is provided for supplying an electrically non-conductive, cooling liquid to the tissue portion.
