Abstract

IMPROVEMENT IN ELECTROCAUTTERY. An electrocautery embodiment is described comprising an elongated cylindrical body having a distal segment (10) with one end provided with a tip (11) and opposite end connected to a pivotable region (30) via a rod (31). , said hinge region (30) interconnected to a fixed proximal segment (20) couplable at the end of a clip (100) attached to a handle (200), with an extendable cable (40) extending into the inner region of the clip ( 100) and the proximal segment (20) of the elongated cylindrical body, said extendable cable (40) having one end fixed to a drive mechanism in the handle (200) and opposite end fixed to the rod (31) of the pivot region ( 30), moving the distal segment (10).

Description

ELECTRIC TRADE IMPROVEMENT

FIELD OF INVENTION

The present invention relates to an improvement in electrocautery. More specifically, it comprises an articulated electrocautery, or hook, which extends the working field within the abdominal cavity.

BACKGROUND OF THE INVENTION

Laparoscopic surgery has radically changed the modern surgeon's arsenal of therapy. The doctor makes a small incision in the navel and introduces a thin telescope called a laparoscope - a fiber optic instrument that allows for diagnostic and therapeutic procedures, hence the name of the exam, in the form of a surgical procedure through which the internal organs can be visualized inside the abdomen and pelvis. .

With the advent of laparoscopic surgery, the use of electrocautery has become a matter of priority interest for the surgeon who wants to delve into the method, since it is the source of numerous complications if used incorrectly or imprudently.

Electrocautery is useful for sectioning and coagulating tissues, and hook electrocautery is important for facilitating depth perception.

The electrocautery of the state of the art is devoid of articulation, being presented at right angles, passing under the fabric to retract it in relation to other more delicate surrounding structures before the application of electric current to the incision.

However, in order to broaden the surgeon's field of work and work the single-access procedure, such as the NOTES (Natural Orifice Transluminal EndoscopicSurgery) procedure, which allows rigid and flexible forceps to be introduced into the same trocar, requiring an electrocautery equipped with jointing, such as improvement in electrocautery being described and claimed in this application.

SUMMARY

In general, the present invention relates to an electrocautery improvement comprising an elongated body having a distal segment with one end having a tip and opposite end connected to a jointed region through a rod, said articulating region connected to a fixed proximal segment couplable at the end of a clip attached to a handle with an extendable cable extending into the inner region of the clip and the proximal segment of the elongated cylindrical body, said extendable cable having one end attached to a handle mechanism at the handle and opposite end attached in the region of the articulation region, moving the distal segment.

It is a feature of the invention that an articulation-enhancing electrocautery enhancement provides the surgeon with an increased working field in the abdominal cavity.

It is characteristic of the invention an improvement in electrocautery that makes it possible to work the NOTES procedure (Natural Orifice Transluminal Endoseopie Surgery).

BRIEF DESCRIPTION OF DRAWINGS

Figure 1 presents a perspective view of the articulated electrocautery. Figure 2 presents a representation of the articulated electrocautery connected to a clamp and grip.

Figure 3 presents a cross-sectional view, showing the mechanism of the joint.

DETAILED DESCRIPTION OF THE INVENTION

The electrocautery improvement, object of the present invention, comprises an elongated cylindrical body provided with two segments (10 and 20) interconnected by a region provided with articulation (30) that allows the upward and downward movement of said cylindrical body.

The distal segment (10) has at one end a butt (11) and at the opposite end a region having a joint (30) and interconnected with a fixed proximal segment (20), proximal said segment (20) coupled to the end of a clip (100). ) connectable to a handle (200).

An extendable cable (40) extends into the inner region of the clip and the proximal segment (20) of the elongated cylindrical body, said extendable cable (40) having one end attached to a drive mechanism on the handle (200) and the opposite end attached to a rod (31) of the articulation region (30), so that by activating the mechanism in the handle (200), the extendable cable (40) moves the rod (31), promoting the articulation of the region (30), with the consequent upward movement and descending from the distal segment (10).

In the distal segment (10) an electrical connection wire (12) is arranged for heating the tip (11) by action of electric current.

Claims (2)
