Abstract

TROCARTER IMPROVEMENT. An embodiment of a changeover is described which comprises an elongate body (100) having at the distal end an instrumental outlet port (10), said elongate body surface (100) with the arrangement of flexible instrument introduction pathways (20). and a pathway for introducing the optics (30) and at the opposite end of the outlet port (10) with straight channels (40) arranged for positioning of hinged rigid forceps and a carbon dioxide insufflation valve (50).

Description

IMPROVEMENT IN EXCHANGE OF THE INVENTION

The present invention relates to an improvement in trade. More specifically, it comprises a surgical instrument for laparoscopic, videolaparoscopic procedures and performing the NOTES (Natural Orifice Transluminal EndoscopicSurgery) technique that allows the introduction of rigid and flexible forceps into the same trocar.

BACKGROUND OF THE INVENTION

Laparoscopy is a minimally invasive surgical procedure performed through a small incision in the navel where a thin telescope called a laparoscope is inserted, a fiber optic instrument that allows performing diagnostic and therapeutic procedures by visualizing the internal organs inside the abdomen and pelvis.

The NOTES (Natural OrificeTransluminal Endoscopic Surgery) surgical technique is an extension of flexible endoscopy's ability to access organs within the abdominal cavity for diagnostic and therapeutic purposes, including performing surgical procedures such as tubal ligation, oophorectomy, partial hysterectomy, gastrojejunostomy, cholecystectomy. , splenectomy and lymphadenectomy.

For this procedure, the use of specific instruments is necessary, in view of the necessary precision and the non-instrument-patient coordination. Specificly developed instruments are used for the similarity of operation of the instruments of endoscopic procedures, such as grasping, dissecting forceps and flexible scissors, which should be coupled to instruments that facilitate handling.

However, during the execution of the NOTES surgical technique, manipulation of the instruments inside the abdominal cavity requires professional dexterity and must have controlled movement independent of the movement of the forceps, ensuring fine control of the distal extremity positioning.

Therefore, the technical literature does not describe or suggest a switch that directly focuses on the area to be manipulated, facilitating the positioning and precision in the movement of the forceps, with introduction of rigid and flexible instruments, such improvement in trocar being described and claimed in the present request. .

SUMMARY

In general, the present invention relates to an exchangeable embodiment comprising an elongate body having at the distal end an instrumental outlet port, said elongate body surface having the flexible instrument introduction arrangement and a pathway for introducing the optics and at the opposite end of the exit portal being arranged. straight channels for positioning rigid articulated tweezers and a carbon dioxide insufflation valve.

The feature of the invention is a trocar which facilitates manipulation and the performance of laparoscopic, videolaparoscopic procedures and the NOTES surgical technique.

It is characteristic of the invention a trocar that provides distal movement independent of the movement of the forceps, with distinct control between the articulated movement of the instrument and the movement of apprehension or dissection of the device ensuring the necessary precision and the hand-instrument-patient coordination.

It is a feature of the invention that a trocar that focuses directly on the area to be manipulated facilitates the positioning and appreciation of the movement of the tweezers.

It is a feature of the invention to have a trocar with straight and flexible instrumental introduction routes.

DETAILED DESCRIPTION OF THE INVENTION

The object of the present invention is an elongated body (100) having at the distal end an outlet port (10) for the instruments.

In the exit portal (10) the instruments are removed in a controlled direction with their own movements, allowing the procedure to be performed with the necessary precision.

The surface of the elongate body (100) has the arrangement for introducing flexible instruments (20) and a path for introducing the optics (30), said pathways (20 and 30) provided with inclination relative to the surface of the elongate body (100) between them. 30 and 60 degrees.

At the opposite end of the outlet port (10) are straight channel (40) for positioning rigid articulated forceps and a carbon dioxide insufflation valve (50) for the formation of a peroperumoneum in the abdominal cavity.

The introduction of flexible instruments (20) presents barriers to maintain the pneumoperitoneum of the abdominal cavity.

Claims (2)

1. TROCARTER IMPROVEMENT characterized by comprising an elongate body (100) having at the distal end an instrumental exit port (10), said elongated body surface (100) with the provision of flexible instrument introduction pathways (20) and a path for introduction of the optics (30) and at the opposite end of the outlet port (10) with straight channels (40) arranged for positioning of articulated rigid tweezers and a carbon dioxide insufflation valve (50). TROCARTER IMPROVEMENT according to claim 1, characterized in that the flexible instrument introduction pathways (20) and the optical introduction pathway (30) are inclined to the length of the elongated body surface (100) between 30 and 60 degrees. .
