Description

Universal Femoral Guide

Object of the invention

The object of the present invention is to a universal femoral guide and belongs to the medical sector and more specifically of surgery and surgical material and consists in an improvement developed on the femoral guidelines of surgical use known so far in the state of the technique, in order to facilitate the understanding of the invention We will first make a brief presentation of the techniques and materials known and in use in this type of surgery.

State of the art

Currently, one of the main problems for reconstruction of the cruciate ligaments, is the placement of the femoral tunnel. An incorrect tunnel position Femoral may be the most important cause of failure of a reconstruction of the anterior or posterior cruciate ligament. For achieve this goal, the femoral guides that allow to practice the femoral tunnel under arthroscopic control.

To perform the femoral tunnel of a anterior cruciate ligament ligamentoplasty there are currently two guide systems: from "outside to inside" (through the tunnel tibial or through an incision in the femoral side) or "inside to outside" (from the joint).

The inconvenience of the guides "out to inside "is that, being rigid, they do not allow the placement of the guide at the desired point or make a femoral incision necessary additional. The most recent "inside out" guides are more versatile but significantly hinder the technique surgical

The originality of this guide, with respect to already designed until today, is that it allows you to place the entrance of the femoral tunnel in the position desired by the surgeon, without depend on other variables, such as the peculiar anatomy of the knee or "rigid" design of other femoral guides.

Description of the invention

The universal femoral guide has at its furthest end a termination with several angles at 20º, 30º and 45º, which can be rotated according to the surgeon's preferences, both for the right and left knee. Another option could be to use the flexible end guide that could have greater versatility because it could move in all three planes of space.

Advantages

The advantages and improvements provided by the guide Femoral perfected here described above in the sector they are fundamentally:

\ sqbullet

Possibility to start and practice the femoral tunnel in any position.

\ sqbullet

Possibility of entering the guide from various locations both from within and from out of the joint.

\ sqbullet

Avoid making incisions anti-aesthetics in other areas of the knee (over everything in the femur).

\ sqbullet

Possibility of double tunnel in the femur.

\ sqbullet

Can practice any technique for ACL reconstruction.

\ sqbullet

Option to practice the femoral tunnel for the reconstruction of PCL without making anti-aesthetic incisions in the femur (femoral guide with flexible end) (in the version incorporating the flexible end Figure 2).

Description of the drawings

As described above and with the purpose of facilitating the understanding of the invention, are attached the designs in which:

Figure 1.1 presents an elevation view lateral femoral guide with angled distal end showing the tab in the terminal.

Figure 1.2 is a top plan view of the femoral guide device incorporating at its distal end a final tab

Figure 1.3 presents an elevation view front of the femoral guide where the light is shown (hollowness) Inside the guide.

Figure 2 shows a side elevation view of the femoral guide incorporating flexible termination.

Preferred Embodiment Example

According to the designs described above, The present invention proposes a cannulated universal femoral guide (1), preferably made of materials such as stainless steel medical grade, titanium or similar with a body of a thickness or diameter between 6-7 mm, provided with a light or distal end opening of about 4.5-5 mm of thickness (2), said cannulated femoral guide is provided with handle Ergonomic fixed (3) that allows its easy and agile handling for use indistinct with right and left hand, said hergonomic handle It has a body length of about 15 cm being its main and newest feature that, at its distal end, has an angled end portion (4) of an approximate length about 15 mm, provided at one end of an extension in the form of a tab of about 4 mm (5), said final portion allows a work in variable angulations between 20 to 45 degrees and eyelash offsets between 5 to 7 mm.

The universal femoral guide also presents the possibility of incorporating wheels or keys (6) in its base, said element allows the following utilities or advantages in handling Of the device; rotation of the guide termination, fixing of the termination in a desired position with the possibility of incorporating mouth needles or flexible guides with drill bit and drill bits flexible with variable diameters from 8 to 10 mm

With the modification of the flexible termination (Figure 2), this femoral guide also presents the possibility of mobility in various directions, by incorporating a final termination of fixation in the form of a skewer in the flexible final portion (7), which impacts on the bone of the femoral notch, in the position decided by the surgeon.

Claims (4)

Universal femoral guide, provided with a body provided with a light or hollow at its distal end and a fixed hergonomic handle, characterized in that at its distal end, it has an angled end portion provided at one of its ends with an extension in the form of eyelash. 2. Universal femoral guide, according to the first claim characterized by incorporating wheels or keys in its base. 3. Universal femoral guide, according to the preceding claims, characterized by allowing needles or flexible guides with drill tips and flexible drills of varying diameters to be incorporated into the mouth. 4.
