Description

CONSTRUCTIVE ARRANGEMENT IN FLEXIBLE PICKUP FOR

CIRCULATE ESOPHAGE

The present utility model describes a constructive flexible retractor arrangement for surrounding the esophagus. More specifically, it comprises a retractor having a flexible distal stem that allows better adaptation to the organ surface without the risk of puncture injury.

The flexible esophageal circling retractors, used in videolaparoscopic surgeries for gastric banding, have the function of moving the organs inside the abdominal cavity to provide an adequate surgical field.

During the procedure, retractors are positioned in the organs near the stomach to allow placement of the gastric band - a ring used to strangle the stomach. In this situation, there is always a risk of injury to the esophagus or stomach during tool placement, which should be carefully handled by the practitioner.

In this situation, flexible retractors flex their extremity to properly support the organ and make its movement without causing trauma.

However, it is found that conventional flexible retractors with articulation can generate sharp corners that risk the patient's organ perforation, bringing complications to the patient.

This inconvenience can be eliminated by the use of retractors made of vertebrae - sequential union of small segments, but these tools do not have the proper rigidity to perform the flexion movement and, after flexing, perform the passage of the gastric band or move an internal organ. of a patient, causing difficulty in performing the surgical procedure.

Thus, in videolaparoscopy surgeries for gastric band placement 5, where it is necessary to move the organs inside the abdominal cavity in order to provide an adequate surgical field, flexible retractors are important tools, but must undergo constructive adaptations to perform the necessary operations. with rigidity and stability.

Thus, the object of the present utility model is a flexible retractor to surround the esophagus which has a distal end provided with a region provided with a mechanical flexion system with controlled movement and satisfactory stiffness for gastric banding and organ removal 15 accurate and safe without causing trauma.

It is characteristic of the utility model a flexible retractor to surround the distal end esophagus with flexible region shaped as multiple interval indentations arranged on the surface of the rod which, when articulated through a mechanical bending system, form a curvature smooth surface, eliminating sharp corners that can cause surgical trauma.

Characteristic of the utility model is a flexible retractor for surrounding the esophagus which has at the distal end a flexible lining that follows the movement of the distal end 25 and prevents contact between the external medium and the flexing mechanism, preventing dirt buildup and facilitating the cleaning the instrument.

In order to better describe the technical characteristics of the flexible retractor to surround the esophagus, the following related figures are presented:

Figure 1 shows the side view of the flexible retractor to surround the esophagus.

Figure 2 presents the perspective view.

Figure 3 shows the flexible area of the tubular rod.

Figure 4 shows a sectional view AA of the flexible retractor, showing the flexing mechanism.

Figure 5 shows a sectional view detailing the flexible area of the rod.

The flexible retractor surrounding the esophagus, object of the present utility model, has a distal end provided with an anatomical cable (10), from said cable (10) orthogonally projecting a tubular rod (20) which presents in the proximity of the proximal end a flexible region (21) formed in the form of multiple interval cutouts, said flexible region (21) articulated through a mechanical bending system disposed in the inner region of said rod (20) and driven on the cable (10).

The handle (10) has a fixed area (101) that allows the user to handle and manipulate the tool, and a movable area (102) actuated by axial rotation that controls the flexion of the flexible region ( 21) of the tubular rod (20).

In the inner region of the movable area (102) of the cable (10) there is disposed a threaded element (103) fixed to a rod (104) whose opposite end is interconnected a fastening element (105) in the inner portion of the flexible region (21). .

By rotating the movable area (102) of the cable (10), the threaded element (103) acts on the rod (104) to extend the direction of rotation of the movable area (102) by displacing the fastener ( 105) which promotes controlled curvature of the flexible region (21) of the rod (20) between 80 and 180 degrees relative to the tubular rod (20).

The surface of the flexible region (21) has multiple interval cutouts arranged perpendicular to the rod (20) with specific dimensionality to perform the necessary and controlled curvature, said flexible region (21) which returns to the initial state upon completion of the 10 reverse rotation. movable area (102) of the instrument cable (10).
