Abstract

Improved flange, used for the assembly of bars and placement of retractors for surgery, consisting of a nut with handle (1), a clamp with hole (2), a flat washer (3) and a clamp pin (4). The clamp pin (4) is through the hole presented by the flat washer (3), then it is introduced through the hole that has the clamp (2) and finally it is threaded on the nut with handle (1). The flat washer (3) receives a bar (5) (6) for each of its faces, allowing the formation of any angle.

Description

Flange perfected.

Object of the invention

The present invention patent application It aims at registering a perfected flange for the assembly of bars and placement of retractors for surgery that incorporates notable innovations and advantages over current flanges used for this purpose.

Background of the invention

The flanges currently used for the assembly of bars and placement of retractors in the field of Surgery presents a difficult configuration to assemble and disassemble, making it difficult for the surgeon to manipulate them.

There are no flanges that allow a change of angle on the bars to be mounted, thereby limiting the positions of the assembly of the same.

In turn, these do not accept different bars diameters, restricting its use to certain bars.

Another drawback they present is that they don't allow the assembly of new additional retractors between two flanges already positioned, having to move or restructure the assembly of retractors already placed.

And finally, they do not allow disassembly for a adequate sterilization

Description of the invention

The perfected flange object of the present registration, eliminates the aforementioned problems, since allows the joining of bars of different diameters, forming between they any angle, in addition to allowing the assembly of several retractors without having to move the retractors already placed, even in closed frames, the assembly being very simple, facilitating the work of the surgeon, providing security and speed.

For this, the perfected flange of the present invention is characterized by being a nut with handle, a clamp with hole, a flat washer and a spike clamp.

The clamp pin passes through the flat washer and hole clamp and is inserted, tapping on the nut with handle.

The flat washer receives for each of its faces a bar, once reached the most convenient position, it thread the nut with handle to block the bars that are positioned in grooves that have both clamps

When sitting the bars on the flat washer, you can get all kinds of angles between these bars, and also multi-positioning of retractors and leaflets where need.

On the operating table are mounted fixing flanges with their corresponding vertical bars and horizontal on which the retractor system is mounted with its corresponding sets of perfected flanges, according to needs

To complete the description below is going to be done and in order to help a better understanding of its characteristics, is accompanied by the present specification, of a set of planes in whose figures, illustratively and not limiting, the most significant details of the invention.

Brief description of the designs

Figure 1 corresponds to a view in perspective and representative of an application of this invention.

Figure 2 corresponds to a view in flange perspective of the present invention.

Figure 3 corresponds to an exploded view of the flange of the present invention.

Description of a preferred embodiment

In view of the commented figures and of according to the numbering adopted, it can be observed in them a preferred but not limiting embodiment of the invention, the which consists of an improved flange (9) consisting of a nut with handle (1), a clamp with hole (2), a washer flat (3) and a clamp pin (4).

The clamp pin (4) is through through the hole provided by the flat washer (3) and the clamp with hole (2), and is threaded on the nut with handle (1).

The flat washer (3) receives for each of its faces a bar (5) (6), once the position has been reached convenient, screw the nut with handle (1) to block the bars (5) (6) that are positioned in grooves that have both clamps (2) (4).

On the operating table (8), figure 1, mount the fixing flanges (7) with their corresponding bars verticals on which the retractor system is mounted with its corresponding sets of perfected flanges (9), according to needs

Claims (5)

1. Flange perfected for the assembly of bars and placement of retractors for surgery, consisting of a threaded or pressure element, two clamps, two bars (5) and (6) characterized essentially because it has a flat washer (3) positioned between the two clamps. 2. Improved flange, according to the preceding claim, characterized in that the threaded or pressure element is a nut with handle (1). 3. Improved flange, according to claim one, characterized in that a clamp has a through hole (2). 4. Improved flange according to claim one, characterized in that a clamp is a clamp pin (4); and because the nut with handle (1) is threaded on the clamp pin (4). 5. Improved flange, according to the preceding claim, characterized in that the clamps (2) (4) have a groove suitable for gripping the bar (5) (6).
