Definitions

  • the present invention relates to an orthopedic retractor with guide for performing accurate and safe osteotomies consisting of a handle to hold the instrument, a spatula to remove and protect muscle tissue, vessels and nerves, and a guide to give direction and precision when cutting, guiding the position of implant placement for subsequent fixation of bone segments.
  • Osteotomy is an orthopedic surgical procedure that allows the correction of bone defects through a cut of this bone and subsequent fixation of the segments in a better position.
  • this technique is widely used to correct knee deformities with arthrosis and angular deviations in the lower limb.
  • the biomedical industry launches a large number of new devices such as retractors, guides, rods, pins, among others, which facilitate the surgical procedure.
  • the most common orthopedic retractors on the market have the sole function of removing tissues to facilitate surgery and increase bone exposure.
  • These instruments come in various formats and can be manual or auto-static.
  • Osteotomies are performed, with constant radiological control, through incisions that allow the surgeon to move away the structures that cannot be injured and expose the bone portion to be cut, to allow osteosynthesis (bone fixation) in the new determined position.
  • the present invention aims to reduce the inherent risks of the bone tissue cutting procedure. Presenting for this purpose a spatula that separates the tissues and vessels of the bone and protects them from the saw used in the cut. This invention allows the use of X-ray and gives the surgeon greater safety during cutting.
  • the instrument also has a guide for the electric saw that gives precision to the cut, with great practicality in its use, because it allows the orientation of the position in which the osteosynthesis plates should be placed. Its greatest advantage is to integrate 4 steps of surgery with only one instrument (bone exposure, removal of structures, osteotomy and orientation of the plates).
  • the other features of the present invention are: -
  • the saw guide is movable for easy adaptation to bones of different sizes.
  • the spatula has slots to identify the progression and alignment of the X-ray saw.
  • the spatula is not sharp to prevent it from cutting tissues and vessels, but has an edge that divuls the tissues by detaching them from the bone, and a geometry that adapts to the bone.
  • the handle is ergonomic and allows the guide to be directed to the best position.
  • the plate coupled to the guide simulates the position in which the definitive osteosynthesis material will be fixed.
  • the plate is movable to facilitate the cutting procedure at different angles.
  • Figure 1 shows a perspective view of the instrument complete with the handle and the spatula (A), the movable guide (B) and the plate itself (C).
  • Figure 2 is a perspective view of the rod (4) and the spatula (1) which will preferably be a single piece. In the spatula there will be cracks (2) and a graduation for the movable guide (3).
  • Figure 3 shows a cross-sectional view drawing attention to the opening of the movable guide (5), the spatula profile (6) and the hook (7).
  • Figure 4 shows some sections of the guide passage profiles (8 and 9) and the rod (10).
  • Figure 5 shows the two sections of the lower guide (11 and 12), saw opening (13) and plate housing (14).
  • Figure 6 is a perspective view of the movable guide (B) with the opening edges (18) rounded to facilitate entry of the saw into the guide.
  • Figure 7 is the plate (C) with the saw opening (16), the upper part for its attachment (15) and the holes for the pins (17).
  • Figure 8 shows the limited movement that the plate (C) must have in relation to the movable guide (B).
  • Figures 9 and 10 show a possible method of fixing the movable guide (C) with the device (D) and the toothed plate (E).
  • Figure 11 shows a possible fastening device (D) for the movable guide
  • the instrument will consist of a part (A) formed by the rod (4) and the spatula (1) ( Figure 2) with an opening (5) for the placement of the movable guide (B) .
  • the movable guide will slide through the opening and its advance or retraction will be measured by the graduation (3).
  • At the front of the guide there will be a notch (14) of the plate (C).
  • the purpose of this plate is to provide orientation for subsequent fixation of the orthopedic implant and will not be fully fixed to allow bone cutting at different angles (Figure 8).
  • the material used in the parts of this instrument shall be resistant to stresses, permit repeated sterilization procedures and shall not be oxidizable.
  • the spatula (1) will not be sharp to damage the noble tissues and will have a curved profile (6) ( Figure 3) to increase the area protected by the saw. Its geometry allows adaptation to the bone anatomy to provide greater stability during cutting. In its extension there will be slots (2) in order to differentiate the blade from the instrumental saw during radiological control and to control the advance and direction of this same saw, and the shape of these slots (2) may vary as long as it does not lose its shape. goal.
  • the movable guide (B) that will be placed and slide through the opening (5).
  • the distance between the tip of the spatula and the plate (C) can be measured by the graduation (3). This variation of measurement is important for the present object as it allows the surgeon to adapt the instrument to different bone sizes.
  • the shape of the aperture (5) will preferably be of trapezoidal shape (8 and 9) to facilitate attachment of the guide.
  • the guide (B) can be fixed by spring, remembering that by vibration of the saw the threaded connections can become an undesirable alternative.
  • the system will be fixed by a toothed plate (E) and a spring device (D) shown in Figure 11.
  • the stem geometry will be ergonomic for the grip of the handle to the surgical glove, comfort and ease of use for the surgeon. Its format is presented in Figure 4 by section (10).
  • FIG 2 another important feature of this invention is the hook (7), where a weight will be placed to maintain the openness of the fabrics, providing stability and eliminating the need for another aid.

  • the edges (18) ( Figure 6) of the saw opening will be rounded to facilitate insertion of the saw blade into the guide.
  • the plate shown in Figure 7 will have two projections (15), one at the top and one at the bottom to be coupled to the guide (B).
  • the measurements (geometry) of these protrusions and housings (14) should allow the movement of the plate ( Figure 8) which, although limited, will facilitate bone cutting at different angles.
  • the board has the opening (16) for the passage of the saw and holes (17) for the placement of the pins.
  • the plate should preferably be flexible to facilitate its attachment to the housings (14). Through these pins the plate will be temporarily fixed to the bone.

Abstract

La présente invention concerne un écarteur orthopédique, avec guide pour réaliser des ostéotomies de manière précise et sûre, comprenant un manche pour fixer l'instrument, une spatule pour écarter et protéger les tissus nobles, en plus d'un guide pour conférer orientation et précision à la coupe, orientant la position de mise en place des implants en vue d'une fixation postérieure des segments osseux. Ce dispositif fait intervenir 4 étapes de chirurgie avec 1 seul instrument (mise à nu de l'os, écartement des structures, ostéotomie et orientation des plaques).
