Definitions
- the present invention is related to a surgical instrument which provides spinal immobility (stabilization) during the fusion of the substitute bone placed after the removal of the damaged vertebra in order to prevent the medulla (spinal cord) from being bruised, as the result ol i damaqe occurred in the vertebral column of a human body due to such reasons as fracture, dislocation, infection and the like.
- spinal immobility stabilization
- the damaged vertebra is removed and replaced by a piece of bone taken from another part of the body.
- the vertebral column must remain immobile during the fusion oi this new bone with the undamaged vertebrae.
- the instruments used currently in order to provide this may be classified in two groups, namely anterior and posterior instruments.
- Anle ⁇ oi devices that is to say the devices that are applied from the lore-part, are related to inserting screws into the vertebral column corpus through the lateral wall of the corpus and providing communication between the rods and these screws.
- the posterior devices i.e. those applied from the back-side, are applied by inserting screws from the peduncle region of the vertebral column and connecting these screws with rods.
- the object is helping the process of fusion by providing immobility during the fusion of the newly placed bone with the undamaged vertebrae, as mentioned doove .
- the disadvantage of the said systems is that it is easily subject to bending or fracturing as the result of being left outside the axis where the loads on the vertebral column are maximum. Furthermore, the insertion oi the screws into critical anatomical regions may lead to injuries during the implementation of these devices.
- Fiqure 1 shows the anterior and posterior systems
- t iqurc 2 is the view of the basic principle of the device according to one embodiment of the present invention
- Fiqure 5 is the view after securing the pieces which prevent rotation according to the first embodiment
- Figure 6 is the view after attaching the connector according to the first embodiment
- Fi ⁇ ic / L I he view after the placement of the bones that will provide the fusion according to the first embodiment .
- Figure 8 is the view of the device after the insertion of the screws (1) into the upper and lower undamaged vertebrae, upon the removal of the damaged vertebra according to the second embodiment.
- Figure 9 is the view of the anti-rotation locking pieces (2) shown after their insertion into the parts of screws ( 1 ) that are left outside the vertebrae according to the second embodiment.
- Fiqure 10 is the view of the connector (3,4) after it is placed onto the lower screw (1) according to the second embodiment .
- Pi u] L 11 is the _ew of the bones intended to provide
- Fi qure 12 is the overal l view of the device according to tne second embodiment .
- the present invention solves the above mentioned problems ana disadvantages by using the instrument of the invention applied from the anterior in order to fasten with screws from the bottom or the top of the corpus instead of screwing up from the lateral wall of the same and I o connect them with an intermediary piece (connector) .
- an intermediary piece connector
- extension pieces on back aftei inserting the said screws (3) into the upper and lower undamaged vertebra.
- the said piece (4) is not required m cases when the fracture does not adversely effect more than one vertebrae .
- the connector piece (2) is connected to the screws. Then the pieces (5) that pievent rotation in this region are driven into the bone after passing through the connectors (2) .
- the instrument is made of stainless steel and titanium.
- Another advantage of the present invention is that it can be elongated as much as required in case more than one vertebrae are broken.
- Ready-packed bones may also be used instead o l vertebra but these bones are weaker, more expensive and more difficult to fuse in structure.
- the anti-rotation lockinq pieces ( ') are directly pushed into the screws y ) without lequiimg the attachment of the connector.
- the connector II (3,4,5) is applied instead of the connector equipped with nuts.
- the said connector II (3,4,5) consists of two pieces (3,5) and fixing screws
- the thickness of the external part is variable according to the type of vertebrae to be placed in (e.g.12 mm at thoracolumbar region) and its exterior surface is rough n order to prevent its slipping from the instruments whereas its inner surface is grooved.
- the inner part (4) consists of two sections.
- the head section is hexagonal or octagonal and allows the use of a spanner and thus the pieces (3,4) slide over each other as they are threaded.
- the section below the head is completely threaded and the piece (4) also varies in length and width, depending on the location and damage of the vertebra. There are two holes on the head section.
- this screw is not drawn tight in the said hole and allows the rotation while the pieces (3,4) are rotated due to their grooves and slided over each other.
- the hole that can be seen from the lateral sides are threaded holes opened according to the fixing screws (5) that are also provided for the piece (3), in order to tighten the hexagonal section of the screw (1) .
- the fixing screws (5) are inserted into these holes in order to lock the pieces (1) and (4) .
Abstract
Cette invention concerne un instrument chirurgical qui permet d'assurer une stabilisation spinale lors de la fusion d'un os de substitution destiné à remplacer une vertèbre dans le corps humain, ladite vertèbre ayant a été retirée suite à un dommage provoqué par une fracture, un déplacement ou une infection, entre autres. Cet instrument permet d'éviter toute contusion de la médulla, ou moelle épinière, et se caractérise par le fait qu'il comprend au moins deux vis de base (1), deux pièces de verrouillage (2) empêchant la rotation de la vertèbre, ainsi qu'une pièce de connexion (3, 4, 5).
