Abstract

An improvement in electrocautery is described, comprising an elongated cylindrical body presenting a distal segment (10) with one tipped end (11 ) and the opposed end connected to a jointed region (30) by a shaft (31 ), with such joint region (30) being interconnected to a fixed proximal segment (20) connectable at the end of forceps (100) fixed at a hilt (200), with an extensible cable (40) that extends itself across the internal region of forceps (100) and the proximal segment (20) of the elongated cylindrical body, with such extensible cable (40) presenting one end fixed at an operation mechanism at the hilt (200) and the opposed end fixed at the shaft (31 ) at the joint region (30), moving the distal segment (10).

Description

IMPROVEMENT IN ELECTROCAUTERY INVENTION FIELD
The current invention refers to an improvement in electrocautery.
More specifically, it comprises an electrocautery, or hook, endowed with a joint, which amplifies the working field inside the abdominal cavity.
INVENTION ANTECEDENTS
Laparoscopic surgeries have dramatically changed the therapeutic arsenal for the modern surgeon. The doctor does a small incision at the navel and introduces a thin telescope called laparoscope - an optic fiber device that enables to perform diagnostic and therapeutic procedures, thus the name of the exam, in the form of a surgical procedure by which the internal organs inside abdomen and pelvis can be visualized. With the coming of the videolaparascopic surgery, the use of electrocautery has become a subject with priority concern for the surgeon that wishes to know more about the method, once it is the source of numberless complications if used in a wrong or imprudent way. Electrocauteries are useful to section and to coagulate tissues, with hook electrocauteries being significant to facilitate the depth perception.
State-of-the-art electrocauteries are jointless and are presented in right angle, passing under the tissue in order to retract it referring to other surrounding more delicate structures before the application of electric current for incision.
However, in order to amplify the working field for the surgeon and to work the single-access procedure, such as NOTES (Natural Orifice Transluminal Endoscopic Surgery) procedure, which enables to introduce stiff and flexible forceps in a same trocar, with a jointed electrocautery being required, and such improvement in electrocautery is described and claimed in the current application. SUMMARY
In general, the current invention refers to an improvement in electrocautery comprising an elongated cylindrical body that presents a distal segment with one of the ends presenting a tip and the opposed end being connected to a jointed region by a shaft, with this joint region being interconnected to a fixed proximal segment connectable to the end of a forceps fixed to a hilt, with an extensible cable that extends itself to the internal region of the forceps and the proximal segment of the elongated cylindrical body, and this extensible cable presenting one of the ends fixed to an operation mechanism at the hilt and the opposed end fixed at the shaft of the joint region, moving the distal segment.
An improvement in jointed electrocautery providing increase in working field for the surgeon in the abdominal cavity is a feature of the invention. An improvement in electrocautery that makes possible to operate
NOTES (Natural Orifice Transluminal Endoscopic Surgery) procedure is a feature of the invention. BRIEF DESCRIPTION OF DRAWINGS
Figure 1 presents the perspective view of jointed electrocautery. Figure 2 presents the representation of jointed electrocautery connected to a forceps and hilt.
Figure 3 presents cross-sectional view, evidencing the joint mechanism. DETAILED DESCRIPTION OF INVENTION
The improvement in electrocautery, addressed by the current invention, comprises an elongated cylindrical body that has two segments (10 and 20) interconnected between themselves by a jointed region (30) that enables ascending and descending movement of such cylindrical body.
The distal segment (10) presents a tip at one of the ends (11) and a jointed region at the opposed end (30) and interconnected to a fixed proximal segment (20), with such proximal segment (20) coupled to the forceps end (100) connectable to a hilt (200).
An extensible cable (40) extends itself across the internal region of the forceps and the proximal segment (20) of the elongated cylindrical body, with such extensible cable (40) presenting one of its ends fixed to an operation mechanism at the hilt (200) and the opposed end fixed at a shaft (31) at the joint region (30), in a way that, by the operation of the hilt mechanism (200), the extensible cable (40) displaces the shaft (31), promoting the region joint (30), with the consequent ascending and descending movement of the distal segment (10). An electric connection wire (12) is place at the distal segment (10) for tip heating (11) by electric current action.
