Definitions
- the present invention relates to a device that facilitates fixation in osteoporotic bones of screws normally used in osteosynthesis of non-pathological bones.
- the device in question has a biocompatible element and an instrument that is used to manipulate it, which would act as a fixing nut after being pierced by the screw that has previously passed the bone cortices, thus providing greater resistance to Threaded joint traction.
- the main technical difficulty lies in how to place a fragment of one of these materials to be pierced by the screw after it has passed the two bony corticals and secure the grip on said fragment.
- a problem that must be solved is the shape and dimensions that these pieces must have in order to prevent them from entering the bone cortex due to the pressures generated on them.
- the device for the fixation of screws in osteoporotic bones is constituted by biocompatible laminar elements that assure the fixation of the screw once it has crossed its structure and an instrument that facilitates the placement of said elements in the bone areas opposite to that of the incision , by manipulating from the side of the cut.
- the purpose is for said biocompatible material to hold the end of the threaded rod of the screw and prevent its loosening.
- the device for fixing osteoporotic bone screws facilitates that, simultaneously with the fixation of the sheet elements on the opposite side of the incision, the placement of washers or plates on the side of the incision.
- the instrument used in the placement of the biocompatible elements for the fixation of screws in osteoporotic bones is constituted by two basic parts, a male and a female, connected to each other by a pair of surface contact, relative movement of linear sliding and a degree of freedom.
- one of the basic parts called the basic male part, has a bar-shaped area with a prismatic profile that can slide through the hole that, with a similar profile, has the so-called female basic part.
- Each of the basic pieces is square bent at one end.
- said folded ends are parallel and form the arms where the pivoting jaws are mounted that allow to hold and hold the elements of biocompatible material that will be fixed to the bone by screws.
- Each of these basic parts has a handle.
- the pair of handles adapts ergonomically to the palm of one hand to facilitate the closing action of the pivoting jaws.
- the base of the handle of the female basic part is perforated along an axis perpendicular to the longitudinal axis of the handle.
- the polygonal bar of the male part is coupled.
- Said hole has a prismatic profile similar to the profile of the bar of the male basic part. The differences lie in the geometric tolerances necessary to allow an adequate play between both pieces and in which the perforation has been carried out a longitudinal recess of straight section to allow the loose passage of the zipper that the prismatic bar has carved in its upper flat surface.
- the length and thickness of the walls of said perforation are those necessary so that there are no blockages or unwanted headers between both pieces and can withstand the mechanical stresses that are generated during operation with the instrument.
- the arms where the pivoting jaws are mounted are parallel and are in the same plane as the handles, but the mouth that makes up both arms is directed in the opposite direction to the direction indicated by the mouth formed by the two handles.
- the force that the user makes with the hand on the handles is that necessary to generate a certain pressure between the pivoting jaws and the bone and to overcome the force of an elastic element that opposes said direction. of movement.
- Said elastic element may be absent.
- the instrument has a locking mechanism.
- the locking mechanism is of the ratchet type.
- the ratchet mechanism is constituted by a push button, an elastic locking element and a saw-shaped zipper, which is carved in the upper flat part of the prismatic profile bar of the male basic part.
- the button is housed in the handle of the female basic part.
- the ratchet mechanism is of the "normally closed” type, that is, if the button is not operated externally, it blocks the opening of the jaws. In order to make the ratchet mechanism of the closed type it has an elastic locking element in the handle of the female basic part.
- the locking button is constituted by a rod that in its lower part has a tooth that can be embedded in the zipper of the basic male part to block the opening of the jaws of the instrument and in its upper part it has means so that, by the pressure of a finger, the force of the elastic locking element can be overcome and the zipper button is disconnected, thereby unlocking the opening of the jaws.
- the mechanism of Ratchet and lock button will not be necessary.
- the female piece will have a threaded hole in one of the side faces of the handle base, through which the polygonal bar of the the male piece. Said threaded drilling will allow the relative movement between the male and female parts to be blocked or unlocked by manually applying a small tightening torque to the head by means of the use of a pressure bolt with an appropriate head to facilitate hand threading. said bolt.
- a form closure or friction closure element located at the end of the prismatic bar of the male basic part.
- the pivoting jaw corresponding to the male basic part is in the form of a rectangular parallelepiped.
- This element has a carved hole in the face that will be in contact with the bone.
- Said hole has the appropriate form to accommodate and transport the biocompatible element that is desired to be fixed and to facilitate the removal of the instrument once the biocompatible element has been fixed to the bone.
- the remaining surface of said face that is not occupied by the hollow is knurled to achieve proper roughness and prevent it from sliding once it has been pressed against the bone.
- This pivoting jaw has a blind cylindrical bore drilled in its geometric center and perpendicularly thereto, where the elements that perform the axis function of the joint are introduced.
- the pivoting jaw mounted on the female basic part is in the form of a six-sided polyhedron.
- Two opposite faces of said polyhedron are not flat but concave and are those that will be in contact with the bone or with the element that will be placed in the bone. These curved faces are differentiated from each other by the geometry of the hole they have practiced on their surface.
- the selection of the face whose Normal is directed to the bone is a function of the type of element to be fixed in the area of the incision. That is, if it is a washer or an osteosynthesis plate.
- the face designed to place washers has a circular hole with the appropriate depth so that it can be properly housed.
- the face designed to place osteosynthesis plates has small tabs that will be inserted into the oval holes of the latter, facilitating the positioning of the instrument and avoiding unwanted slipping of the same with respect to the plates.
- the upper and lower faces of this pivoting jaw have a blind cylindrical bore drilled in its geometric center. Said drill is perpendicular to said faces and is where the elements that perform the axis function of the joint are introduced.
- the pivoting jaws To allow the passage of the bits that have to pierce the bone and the biocompatible fasteners that require it, as well as the advance of the screws that are inserted, the pivoting jaws have through holes perpendicular to the faces that will be in contact with the bone.
- the arm where the pivoting jaw corresponding to the female basic part is mounted once the instrument has been assembled, is perpendicular to the prismatic bar of the male basic part.
- the arm where the pivoting jaw corresponding to the male basic part is mounted is perpendicular to the longitudinal axis of its prismatic bar. Therefore, the two arms where the pivoting jaws are mounted are parallel.
- Each of the two arms where the pivoting jaws are mounted has two plates perpendicular to it and parallel to each other. The plates of one arm will face those of the other arm, but their longitudinal axes do not have to be coincident. These plates are cantilevered and serve as support for their respective pivoting jaw.
- the plates have threaded holes where the elements to be used as the pivot axis of the pivoting jaw are connected.
- the pivoting jaw installed in the female basic part can rotate with respect to its axis of rotation 360 ° without stumbling, allowing this feature to choose the face of the pivoting jaw. that he has to face the bone; This choice will depend on the type of element to be placed, that is, if it is a washer or an osteosynthesis plate.
- the arm where the pivoting jaw of the female basic part is mounted has an element designed to allow the passage of the thymes to be inserted in the bone and to easily attach different drill guides appropriate to the drill diameter that you wish to use in every moment
- the biocompatible fixation pieces are laminar-shaped elements of biocompatible plastic material that are placed in the areas of the bone opposite the incision by manipulation from the side of the cut. These elements are placed on the instrument, on the jaw face of the male part that faces the jaw of the female part. In this way, when the jaw of the male part contacts the bone, it also makes contact with it to the fixing piece so that the drill or the screw that has previously passed through the jaw of the female part and the two corticals of the bone penetrate directly into the biocompatible fixation piece.
- the purpose is for said biocompatible material to hold the end of the threaded rod of the screw and prevent its loosening.
- the biocompatible fixing piece can have a perforation of less than the smaller diameter of the thread of the osteosynthesis screws in its center, so that they can be self-tapped in said perforation or be introduced prior to thread drilling with the appropriate instruments.
- the fixing element of the invention which has a laminar shape, can be placed on flat bones or bones with certain convexity, therefore, the surface that will be in contact with the bone cortex may be flat or concave in order to adapt the best possible to the cortical surface of the bone.
- the surface that will be covered by the fabrics will have the appropriate shape and finish for a better adaptation of the same and prevent them from causing damage.
- the thicknesses of the fasteners will be a function of the thread pitch of the osteosynthesis screws that are used and the mechanical strengths that are required.
- the present invention has the advantage over others previously described that the threading within the biocompatible element that ensures the screw fixation is carried out at the time of its introduction. Being pre-drilled and preferably made of plastic material, it will generally not be necessary to use a thread prior to the introduction of the screw, since the thread will be created by the advance of the screw itself within the fixing element. This will allow the use of any type of screw in all fasteners, which will significantly reduce the process of Manufacturing and use
- the instrument used to place the fixing element is essential for the introduction of the screw into it. Since the advancing end of the screw is usually not visible to the surgeon, the placement of the fixation element would be very complicated done manually.
- the instrument of the present invention has jaws and a system of guides that ensure that the screw introduced by the jaw of the female part always finds the bore of the element placed in the jaw of the male part. When the screw is inserted into the fixing element, it is easily released from the jaw that contains it and is pressed against the bone, ensuring the stability of the screw inside the bone, acting as a locking nut.
