Description

A ROD SYSTEM Field of the Invention
This invention is related to a rod system that has the ability of transmitting the data (force, deformation, displacement, etc.) created on itself when inside the body to an external media.
Background of the Invention
Spinal surgery involves the operations and various interventions performed on the spinal cord and the nerve roots and the spine that surrounds/protects this sensitive nerve tissue. Various diseases of the spine and the spinal cord lead to clinical diseases by causing structural, functional and/or mechanical disorders. Spine, spinal cord and nerve roots are affected by several disease groups and as a consequence clinical symptoms and indications occur in the form of mainly pain, loss of nervous system functions such as paralysis and loss of sense, restrictions on the movement of the spine and deformity. Among the most frequently encountered disease groups in the clinical practice are Disc disorders (herniated disc and cervical disc hernia ...), Traumas (reasons such as Traffic accidents and falling from height). In such cases, it may be required to fix one or more vertebra to each other. Fixing the vertebras to each other is performed by holding components and rods. The holding components are inserted to the spine and fixed. Then, fixation of all these holding components to each other is implemented by a rod mounted to the top of the screws. The mentioned rod has a certain thickness and preferably has a cylindrical geometry. After the rod and the holding components are installed inside the body, they remain entirely enclosed inside the body and no intervention can be made without surgical operation. Moreover, loads at varying rates bear on the rod when the patient moves. In some cases, depending on the continuity of the loads, these rods may break in the body due to fatigue. Breaking of the rod may cause a serious trauma for the patient. Since the rods used today have no data transfer to outside feature, no information can be obtained about the state of the rod inside body.
In the United States patent document No.US8202302B2 of the known state of the art, a system fixed by holding components and rods is mentioned.
Object of the Invention
The object of this invention is to provide a rod system that can transfer data to an external medium when inside the body.
Another object of the invention is to provide a rod system that enables measurement of the force acting on the rod, direction of the force, displacement, direction of displacement, deformation, direction of deformation and similar data as long as preferred.
Detailed Description of the Invention
The rod system that is embodied to achieve the objects of the invention is shown in the appended figures, in which;
Figure 1. is the perspective view of the rod system.
Figure 2. is the perspective view of the rod together with the holding component on the spine.
Reference numbers are individually assigned to the parts in the figures and these numbers refer to: 1. Rod system
2. Holding component
3. Screw head (holder)
4. Rod
5. Sensor
6. Transmitter
7. Receiver
8. Display In its basic form, the rod system ( 1 ) that has the feature of transferring the data (force, displacement, deformation etc.) created on itself when inside the body to an external medium and also that enables measurement of the data (force, displacement, deformation etc.) on the rod comprises;
- at least one holding component (2) that can be fixed to spine, hard or soft tissue,
at least one holder (3) that can be fixed on the head of the holding component (2),
at least one rod (4) that enables connection of holding components (2) installed inside the spine with each other,
- at least one sensor (5) that is positioned on the rod (4) and that measures the data such as the force acting on the rod (4) by the holding components (2), direction of the force, displacement, direction of the displacement, deformation, direction of the deformation and the like,
- at least one transmitter (6) that is located inside the sensor (5) and that transmits the data measured by the sensor (5) to an external medium from within the body,
- at least one receiver (7) that enables obtaining the data provided by the transmitter (6),
at least one display (8) that enables displaying and analyzing the data obtained by the receiver (7). In the rod system ( 1 ) included in an embodiment of the invention, there is a holding component (2) mounted on the spine. The holding components (2) are mounted on the pedicle regions of all the vertebras that are preferred to be fixed. However, the holding components (2) can be mounted on any region of the vertebras. Besides, they can be fixed on any region on the vertebra. After the holding components (2) are installed to the vertebras, a holder (head) (3) is installed on the head part of each holding component (2). A rod (4) having one or more sensors (5) is installed on the holders (3). Thus, all holding components (2) are connected to each other and so the vertebras are fixed. During the movement of the patient towards any direction, a load acts on the vertebras from various angles. These loads are transferred to the holding components (2) via vertebras and then to the rod (4). When the patient bends/stretches or moves in the general sense, various (bending, twisting, pulling and compression) forces from many directions act on the rod (4). By the influence of these forces, various deformations and stresses are created on the rod (4). The measurement of these data (force, direction of the force, displacement, direction of displacement, deformation, direction of deformation and similar data) is performed by one or more sensors (5) located on the rod (4). The sensor (5) measures the forces acting on the rod (4) and enables transferring said data to an external medium from within the body via the transmitter (6). The sensor (5) can transmit said data directly by itself as well as via the transmitters (6). The data sent to external medium by the transmitter (6) is gathered by the receiver (7) and sent to the display (8). Thus, all the data such as force, direction of the force, displacement, direction of displacement, deformation, direction of deformation and the like created by the holding components (2) on the rod (4) can be both displayed and analyzed on the display (8).
