Definitions
- the invention relates to an implant for intersomatic fusion of two adjacent vertebrae, having a first implant part and a second implant part that is adjustable relative to the former, for the purpose of distraction.
- Implants for intersomatic fusion of two vertebrae are used in order to stabilize a segment of the spinal column after the resection of a disk that was considered necessary.
- a differentiation is made between operating techniques, with regard to access to the spinal column from the back or from the abdominal side, and fundamentally, different general conditions apply for these.
- the spinal cord In the case of access that takes place from the posterior direction, the spinal cord must be pushed out of the operation region as gently as possible, for the necessary measures for removing the disk, preparing the vertebrae, and inserting the implant to be carried out in the immediate vicinity of the spinal cord, and for the operator to make do with little room.
- first implant part and the second implant part are structured so that they supplement one another, in a complementary manner, in the non-distracted state, to form a pipe that is divided in the longitudinal direction.
- Guide surfaces that extend radially in the distraction direction and rest against one another are formed on the first implant part and the second implant part. Means are provided for fixing the relative position of the guide surfaces in place.
- Such an embodiment of an implant has the advantage that because of the pipe-shaped configuration of the implant in the basic state, as well as the distraction that takes place perpendicular to the pipe axis, a very stable implant that withstands great stress is produced, which can have small dimensions in the distraction direction, in the case of a short but appropriate expanse in the longitudinal direction, so that there is only a small need for space when introducing the implant past the spinal column, between the vertebrae.
- the guide surfaces ensure that a precisely defined movement progression takes place in the adjustment of the two implant parts relative to one another.
- the guide surfaces are used, at the same time, in order to permanently fix a relative position of the two implant parts in place once it has been achieve. This, in turn, promotes the compact construction form of the implant, since no additional, extensive structures are needed to prevent the two implant parts from becoming incorrectly placed relative to one another.
- the pipe has a circular cross-sectional shape in the non-distracted state, and forms a cylinder.
- the cylinder is characterized by its simple geometrical shape, which is easy to produce, and is connected with a great ability to withstand stress.
- the guide surface of the first implant part is formed on its face, and that the guide surface of the second implant part is formed in a radially running slit, namely on the inside of a face plate.
- the slit preferably widens radially, in the direction of the first implant part.
- the face plate is preferably formed in two parts with the second implant part and is adjustable in the axial direction.
- the guide surface of the first implant part is preferably formed on a guide wedge that engages into the slit, having wedge walls that run parallel to the slit walls.
- the guide wedge is formed, in the circumference direction, as a ring open on one side, which surrounds the guide tab with its ring opening in the non-distracted state.
- an axially running threaded bore is formed in the face plate, on the side that faces inward, and a ring eye is formed on the second implant part, to hold a locking screw that engages in the threaded bore, as means for fixing the relative position of the first implant part and the second implant part in place.
- Fixation of the two implant parts in place can take place simply by turning the locking screw in the threaded bore, or they can be released again, whereby it should be noted that in order to activate the means for fixation, access to the implant merely has to be provided in the axial direction, in other words in the direction in which the space is already available, through which the implant was introduced into its position.
- Simple access to the locking screw is achieved in that an implant opening for access into the interior of the implant is formed on the side opposite the face.
- a plurality of guide grooves is formed in the implant opening, two of which run along the longitudinal parting between the first implant part and the second implant part. These guide grooves are provided, in this connection, in order to offer the operator an access possibility for adjusting the two implant parts, in precisely defined manner.
- first implant part and the second implant part are made of surgical steel and/or titanium.
- bone cement that is introduced between the first implant part and the second implant part is also suitable as a means of fixation.
- An instrument that is particularly suitable for placement and distraction of the implant comprises a hollow rod connected with a handle, which rod has a pivotable setting element at its front, free end.
- the element has two pins for insertion into the two guide grooves assigned to the longitudinal parting.
- a sleeve is connected with a pivot lever, which serves for activating a tension piece that engages on the setting element, for pivoting.
- a hollow screwdriver is arranged in the hollow rod, through which screwdriver a threaded pin to be screwed into the threaded bore of the screw head passes.
- the implant can be set onto this instrument, in simple manner, in that the pins are inserted into the guide grooves and the screwdriver, together with the threaded pin, is brought into contact with the screw head, in such a manner that the threaded pin is screwed into the threaded bore in order to absorb tensile forces, and the screwdriver rests against the screw head only with a positive lock, in usual manner, in order to be able to exert rotation forces onto the screw.
- the two guide surfaces of the two implant parts can be displaced relative to one another.
- the displacement is brought about by operating the pivot lever, which brings about a rotation of the setting element, which produces spreading of the guide grooves perpendicular to the longitudinal parting, with the resulting adjustment of the two implant parts relative to one another.
- This adjustment once it has been achieved, can be fixed in place again by activating the locking screw, using the screwdriver.
- a rod thread is formed on the back end of the hollow rod, with a threaded ring arranged on it, to limit the setting path of the sleeve.
- the tension piece engages at the top end of the setting element.
- Projections are formed on the hollow rod, in the front region, at the opposite rod walls. These projections define a pivot axis that lies perpendicular to the longitudinal parting of the implant, and the setting element rests against the projections at a distance from its connection with the tension piece. In this manner, the pivot movement of the setting element is introduced with little need for space, by exerting tensile forces on the setting element.

Description
- This application is a divisional of U.S. patent application Ser. No. 10/854,650, filed on May 26, 2004, which claims priority under 35 USC §119 of German Application No. DE 103 24 319.4, filed on May 27, 2003.
- 1. Field of the Invention
- The invention relates to an implant for intersomatic fusion of two adjacent vertebrae, having a first implant part and a second implant part that is adjustable relative to the former, for the purpose of distraction.
- 2. The Prior Art
- Implants for intersomatic fusion of two vertebrae are used in order to stabilize a segment of the spinal column after the resection of a disk that was considered necessary. In the case of the operating method, a differentiation is made between operating techniques, with regard to access to the spinal column from the back or from the abdominal side, and fundamentally, different general conditions apply for these. In the case of access that takes place from the posterior direction, the spinal cord must be pushed out of the operation region as gently as possible, for the necessary measures for removing the disk, preparing the vertebrae, and inserting the implant to be carried out in the immediate vicinity of the spinal cord, and for the operator to make do with little room.
- It is therefore an object of the invention to develop an implant of the type stated above in such a manner that the construction form can be made smaller, in particular, the length can be reduced, while completely maintaining the distraction possibility and simple operation of the implant for distraction in the operating field, in situ.
- In the invention, the first implant part and the second implant part are structured so that they supplement one another, in a complementary manner, in the non-distracted state, to form a pipe that is divided in the longitudinal direction. Guide surfaces that extend radially in the distraction direction and rest against one another are formed on the first implant part and the second implant part. Means are provided for fixing the relative position of the guide surfaces in place.
- Such an embodiment of an implant has the advantage that because of the pipe-shaped configuration of the implant in the basic state, as well as the distraction that takes place perpendicular to the pipe axis, a very stable implant that withstands great stress is produced, which can have small dimensions in the distraction direction, in the case of a short but appropriate expanse in the longitudinal direction, so that there is only a small need for space when introducing the implant past the spinal column, between the vertebrae. In this connection, the guide surfaces ensure that a precisely defined movement progression takes place in the adjustment of the two implant parts relative to one another. The guide surfaces are used, at the same time, in order to permanently fix a relative position of the two implant parts in place once it has been achieve. This, in turn, promotes the compact construction form of the implant, since no additional, extensive structures are needed to prevent the two implant parts from becoming incorrectly placed relative to one another.
- It has proven to be advantageous if the pipe has a circular cross-sectional shape in the non-distracted state, and forms a cylinder. The cylinder is characterized by its simple geometrical shape, which is easy to produce, and is connected with a great ability to withstand stress.
- According to a particularly preferred embodiment of the invention, the guide surface of the first implant part is formed on its face, and that the guide surface of the second implant part is formed in a radially running slit, namely on the inside of a face plate. This achieves the result that the components that are required for the precise adjustment of the two implant parts, as well as for their reciprocal fixation in place, extend radially from the surface of the pipe towards the inside, and therefore no increased need for space is required for these components during insertion of the implant.
- The slit preferably widens radially, in the direction of the first implant part. The face plate is preferably formed in two parts with the second implant part and is adjustable in the axial direction. The guide surface of the first implant part is preferably formed on a guide wedge that engages into the slit, having wedge walls that run parallel to the slit walls. By means of this configuration, the relative position of the two implant parts relative to one another can be fixed in place by means of jamming, and can be released again. A reinforcement of the fixation occurs by means of the slit and by means of the guide wedge if the implant is placed under stress, since the guide wedge is pressed into the slit and increases the contact pressure between the guide surfaces with its wedge walls, and thereby increases the frictional engagement.
- Since a displacement of the two implant parts relative to one another in the axial direction also occurs during an adjustment of the two implant parts relative to one another in the distraction direction, because of the inclined configuration of the slit walls and the wedge walls, an axially running guide groove is formed in the face plate, for interaction with a guide tab formed on the second implant part. In this way, the axial adjustment of the two implant parts relative to one another also takes place in precisely defined manner.
- In order to achieve the greatest possible length of the guide surface, the guide wedge is formed, in the circumference direction, as a ring open on one side, which surrounds the guide tab with its ring opening in the non-distracted state.
- With regard to a low need for space, it is advantageous if an axially running threaded bore is formed in the face plate, on the side that faces inward, and a ring eye is formed on the second implant part, to hold a locking screw that engages in the threaded bore, as means for fixing the relative position of the first implant part and the second implant part in place. Fixation of the two implant parts in place can take place simply by turning the locking screw in the threaded bore, or they can be released again, whereby it should be noted that in order to activate the means for fixation, access to the implant merely has to be provided in the axial direction, in other words in the direction in which the space is already available, through which the implant was introduced into its position.
- Simple access to the locking screw is achieved in that an implant opening for access into the interior of the implant is formed on the side opposite the face.
- A plurality of guide grooves is formed in the implant opening, two of which run along the longitudinal parting between the first implant part and the second implant part. These guide grooves are provided, in this connection, in order to offer the operator an access possibility for adjusting the two implant parts, in precisely defined manner.
- If a threaded bore is formed in the free end of the screw head of the locking screw, then there is the possibility of absorbing tensile forces that act on the implant by screwing in a threaded pin, and thereby counteracting a change in the position of the implant, as a whole, during distraction.
- Secure anchoring of the implant in the surfaces of the adjacent vertebrae that lie against the implant is promoted in that the surfaces of the pipe that lie opposite one another in the distraction direction have teeth. It is furthermore advantageous if the first implant part and the second implant part are made of surgical steel and/or titanium.
- Alternatively or additionally, bone cement that is introduced between the first implant part and the second implant part is also suitable as a means of fixation.
- An instrument that is particularly suitable for placement and distraction of the implant comprises a hollow rod connected with a handle, which rod has a pivotable setting element at its front, free end. The element has two pins for insertion into the two guide grooves assigned to the longitudinal parting. On the hollow rod, a sleeve is connected with a pivot lever, which serves for activating a tension piece that engages on the setting element, for pivoting. A hollow screwdriver is arranged in the hollow rod, through which screwdriver a threaded pin to be screwed into the threaded bore of the screw head passes. The implant can be set onto this instrument, in simple manner, in that the pins are inserted into the guide grooves and the screwdriver, together with the threaded pin, is brought into contact with the screw head, in such a manner that the threaded pin is screwed into the threaded bore in order to absorb tensile forces, and the screwdriver rests against the screw head only with a positive lock, in usual manner, in order to be able to exert rotation forces onto the screw. After the locking screw has been loosened, the two guide surfaces of the two implant parts can be displaced relative to one another. The displacement is brought about by operating the pivot lever, which brings about a rotation of the setting element, which produces spreading of the guide grooves perpendicular to the longitudinal parting, with the resulting adjustment of the two implant parts relative to one another. This adjustment, once it has been achieved, can be fixed in place again by activating the locking screw, using the screwdriver.
- In order to obtain the greatest possible control during the distraction, it is provided that a rod thread is formed on the back end of the hollow rod, with a threaded ring arranged on it, to limit the setting path of the sleeve.
- The tension piece engages at the top end of the setting element. Projections are formed on the hollow rod, in the front region, at the opposite rod walls. These projections define a pivot axis that lies perpendicular to the longitudinal parting of the implant, and the setting element rests against the projections at a distance from its connection with the tension piece. In this manner, the pivot movement of the setting element is introduced with little need for space, by exerting tensile forces on the setting element. These forces are translated into an adjustment of the two implant parts that takes place in the radial direction.
- A stirrup is mounted on the handle, which can be pivoted between a position that limits the axial adjustment path of the threaded pin, and a position that eliminates this limitation.
