Abstract

A flexible retractor constructive arrangement for surrounding the esophagus is described. A flexible retractor constructive arrangement for surrounding the esophagus allows for better adaptation to the organ surface without the risk of puncture injury, comprising an anatomical cable (10) with orthogonal projection of a tubular rod (20) having near the proximal end a flexible region (21) with a surface provided with multiple interval cutouts arranged perpendicular to the rod (20), said cable (10) having a fixed area (101) and an area 102 which has a threaded member (103) fixed to a tie rod (104) whose opposite end is interconnected with a fastener (105) in the inner portion of the flexible region (21) which controls the flexion of the flexible region (21) of the tubular rod (20).

CONSTRUCTIVE ARRANGEMENT IN FLEXIBLE REMOVER TO CIRCUNDATE ESOPHAGUS

The present utility model describes a constructive arrangement in a flexible retractor to surround the esophagus. More specifically, it comprises a retractor equipped with a flexible distal stem that allows better adaptation to the organ surface, without the risk of injury by perforation.

The flexible retractors to surround the esophagus, used in laparoscopic surgeries to place a gastric band, have the function of removing the organs within the abdominal cavity in order to provide an adequate surgical field.

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

In this situation, the flexible retractors flex the extremity to adequately support the organ and move it without causing trauma.

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

This inconvenience can be eliminated through the use of retractors made up of vertebrae - sequential union of small segments, however these tools do not have the adequate stiffness to perform the flexion movement and, after

2/4 flexed, perform the passage of the gastric band or move an internal organ of a patient, making it difficult to perform the surgical procedure.

Thus, in laparoscopic surgeries for gastric band placement, where it is necessary to separate the organs within the abdominal cavity in order to provide an adequate surgical field, flexible retractors are important tools, but they 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 that has a distal end provided with a region provided with a mechanical flexion system with controlled movement and satisfactory stiffness for the passage of gastric band and removal of organs in a precise way and safe, without causing trauma.

The utility model is characterized by a flexible retractor to surround the esophagus with a distal end with a flexible region shaped in the form of multiple interval cutouts arranged on the surface of the nail that, when articulated through a mechanical flexion system, form a curvature of smooth surface, eliminating sharp corners that can cause surgical trauma.

The utility model features a flexible retractor to encircle the esophagus that has a flexible lining at the distal end that accompanies the movement of the distal end and avoids contact between the external environment and the flexing mechanism, preventing the accumulation of dirt and facilitating cleaning the instrument.

In order to better describe the technical characteristics of the

3/4 flexible retractor to surround the esophagus, the following figures are presented:

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

Figure 2 shows the perspective view.

Figure 3 shows details of the flexible area of the tubular stem.

Figure 4 shows a cross-sectional view of the flexible retractor, showing the flexion mechanism.

ίο Figure 5 shows a sectional view detailing the flexible stem area.

The flexible retractor to surround the esophagus, which is the object of the present utility model, has a distal end provided with an anatomical cable (10), starting from said cable (10) orthogonally projecting a tubular rod (20) which presents in the vicinity of the end proximal a flexible region (21) conformed in the form of multiple interval cutouts, said flexible region (21) articulated through a mechanical flexion system arranged in the internal region of said rod (20) and with activation on the cable (10).

On the handle (10) there is a fixed area (101) that allows the user to pick up and manipulate the tool, and a mobile area (102) actuated by means of rotation in the axial direction that controls the flexion of the flexible region ( 21) of the tubular rod (20).

In the inner region of the mobile area (102) of the cable (10), a threaded element (103) is fixed on a rod (104) whose opposite end is connected a fixing element (105) in the inner portion of the flexible region (21) .

By rotating the movable area (102) of the cable (10), the element

4/4 threaded (103) acts on the rod (104) in order to promote the stretching in the direction of rotation of the mobile area (102), displacing the fixing element (105) that promotes the controlled curvature of the flexible region (21) of the rod (20) between 80 and 180 degrees in relation to the tubular rod (20).

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