Definitions

• the present invention relates to a handpiece for electrical scalpels
• a handpiece for electrical scalpels In the field of electrosurgery, there are many well-known electrical scalpels controlled by means of a handpiece of the type called technically cut-coag and foot-switch, used by the surgeon to cut and coagulate in the course of surgery
• the purpose of the present invention is to eliminate the aforesaid drawbacks and to make available an electrical scalpel handpiece with perfect electrical insulation and shaped in such a way as to provide the surgeon with a firm, comfortable and slip-proof gr ⁇
• An additional purpose is to allow to associate the fume evacuator or fluid aspirator, as well as a light source, to the handpiece
• control circuit is housed in a silicone sleeve, sealed at its ends
• the control circuit is activated preferably by sealed switches with double unstable contact, which can be activated from outside the sleeve
• the grip comp ⁇ ses a central body divided into at least two shells and with such a shape as to appear as a bulge with respect to the parts above and below said central body
• FIG. 1 is a side view of the electrical scalpel handpiece
• FIG. 2 is a partially exploded side view of the electrical scalpel handpiece
• 1 indicates in its entirety a handpiece for an electrical scalpel comprising a g ⁇ p formed by a bulged central body 2 divided into two asymmetrical shells
• An upper shell 2a has two circular holes into which are fitted two corresponding push ⁇ buttons 3.
• a lower shell 2b larger than the previous one, is provided with two coaxial holes 4 through which a tube of a fluid or fume aspirator, or an optical fibre, or a lamp or another type of light source can be inserted into the shell.
• the aspirators or the light source are instruments which can be associated to the electrical scalpel as a result of adopting the original shell 2b.
• the two shells 2a and 2b are shaped in such a way as to wrap around a control circuit 5 of the electrical scalpel, comprising a printed circuit, which is originally protected by a sealed silicone sleeve 6 whose sides are fixed onto two elements 7 and 8, which are part respectively of a front portion 9 and of a rear portion 10 of the handpiece.
• To front portion 9 is affixed the surgical instrument, not depicted because it is well- known.
• an electrical power supply cable 1 1 Into rear portion 10 is inserted an electrical power supply cable 1 1 , which is held in place by means of an "O-ring" gasket 12 which provides a hermetic seal, and cable holder 13 which grips cable 1 1 when a threaded element 14 is screwed onto an external thread 15 presented by rear portion 10.
• Push-buttons 3 act on the corresponding switches 16, which are hermetically sealed with double unstable contact, soldered directly onto the printed circuit board set between the forward and the rear portion of the handpiece.
• one push-button activates the cutting instrument and the other one activates the coagulator.
• Handpiece 1 with its central area 2 shaped as a bulge allows the surgeon simultaneously to use the handpiece not only in its actual cutting and coagulating function, but also as a fluid aspirator, fume evacuator, or light source
• Another alternative is to house a light source in shell 2b to shed light on the area where the surgery is to be performed
• the elements comprising the handpiece are such that neither screws, nor glued or welded parts are required to assemble the handpiece, as is clearly illustrated by figures
• the two shells 2a and 2b of central body 2 are assembled by simple coupling and are locked in place by means of two sleeves 18 which are inserted around semi-cylindrical protuberances 17 presented by both ends of the shells
