Definitions
- the invention relates to a device for measuring the activity of the spinal cord of a vertebrate.
- activity is meant here any variation of an optical, chemical or physical property of the spinal cord which can characterize in particular a neuronal reaction to a motor or cognitive act.
- a motor act results from a set of energetic processes carrying a nerve signal via the spinal cord to the effector organs. Partial or total damage to the spinal cord leads to a degeneration of the nerve pathways that can no longer transmit signals to the spinal neurons underlying the lesion, which can lead to paralysis and an interruption of the ascending pathways to the nerve pathways. the brain that leads to an abolition of sensations.
- HbO oxygenated hemoglobin
- Hb deoxygenated
- the neuronal tissues of the brain could thus be studied.
- the technology used is too large to be placed on another part of the body or to be implanted chronically in a vertebrate. While a trepanation is enough to access the tissues
- the known optical imaging device mainly comprises optical fibers whose use in the spinal cord is difficult because their geometry makes it difficult to integrate the fibers in a simple way to measure the hemodynamic response.
- MRI Magnetic Resonance Imaging
- the invention relates to an implantable device for measuring an activity of the spinal cord of a vertebrate while avoiding the aforementioned difficulties.
- a device for measuring a spinal cord activity of a vertebrate comprising at least one chronically implantable main probe, the main probe being shaped to be attached to a spinous process of a vertebra and maintain in position on either side of the vertebra at least one emitter for emitting a wave capable of interacting with the spinal cord and at least one associated receptor for receiving the wave having interacted with the spinal cord and generated a signal representative of spinal cord activity.
- the main probe is placed very simply by incising at the place of the vertebra concerned and by spreading the muscles on both sides of this vertebra so as to ride it. It remains then to fix the main probe to the vertebra by screwing or gluing it to the apophysis.
- the intervention is simple and fast.
- FIG 1 is a perspective view of a vertebra equipped with a main probe according to the invention
- FIG. 2 is a cross-sectional view of the vertebra equipped with a main probe illustrated in FIG. 1;
- FIG. 3 is a perspective view of the main probe illustrated in FIG. 1;
- FIG. 4 is a cross-sectional view of a vertebra equipped with a main probe and an associated auxiliary probe, according to the invention
- FIG. 5 is a perspective view of the auxiliary probe illustrated in FIG.
- the invention is illustrated in application to a cat vertebra. This application is of course not limiting.
- the measuring device of the invention comprises a main probe 1 shaped to be fixed on an apophysis 2 of a vertebra 3.
- the main probe 1 in infrared-transparent resin, is in the form of form of a jumper 4 having two wings 4a and 4b and a pallet 5 which protrudes from the rider 4.
- This morphology allows a simplified surgical procedure, the surgeon having only to remove the muscles located on the sides of the vertebra 3 and to place the rider 4 on the apophysis 2 in the direction of the arrow shown in FIG. 1. In this position, the rider 4 overlaps the part of the vertebra forming the medullary canal and the pallet 5 extends opposite the apophysis 2.
- the main probe 1 is then preferably fixed at the pallet 5 to the process 2, for example using a biocompatible adhesive, or using titanium screws.
- the wing 4a carries an infrared transmitter 6 whose radiation passes through the spinal cord 7 of the vertebra and is captured, after its interaction with the medullary tissues, by an infrared receiver 8 carried by the other wing 4b.
- the infrared radiation passes through the bone wall and interacts with the hemoglobin of the blood contained in the marrow 7, which makes it possible to follow a vascular activity of the marrow 7 when it is requested.
- the receiver 8 transforms the received radiation into an electrical signal representative of this vascular activity, itself representative of a neuronal activity.
- the main probe 1 comprises electronic means 9 for converting this electrical signal into digital data. These digital data are here stored in a memory and transmitted later.
- the main probe 1 comprises an infrared transmitter 10 and an infrared receiver 11 to communicate by binary frame with an infrared transmitter-receiver remote from the main probe 1.
- the digital data is transmitted in real time, without being stored .
- the digital data thus generated are advantageously sent to a remote transmitter-receiver D to monitor the vascular activity of the spinal cord in response to stimulation thereof.
- the transceiver may for example be associated with a external control box adapted to control actuators acting on the vertebrate body to overcome an insufficiency thereof.
- the control box may be used to control a pump or implant delivering a chemical in response to the detection of marrow activity by means of the main probe.
- the power supply of the main probe 1 is carried out here using a circuit outside the main probe 1 which provides a variable magnetic field thus causing the appearance of a current in an antenna 12 disposed here in the pallet 5.
- the electronic means 9 are adapted to condition the potential induced in the antenna 12 to a potential directly usable by the main probe 1.
- this potential for charging an onboard battery 13.
- the remote transceiver D may be, associated with an auxiliary probe 14 implanted inside the vertebra 3, to be in direct contact with the spinal cord 7.
- the surgeon performs a laminectomy of the vertebra, introduces the auxiliary probe 14 into the medullary canal and reconstitutes the vertebra with the aid of a polymer resin.
- each probe comprises magnets 15, 16, the magnets of the same probe being of the same polarity, opposite that of the magnets of the other probe.
- the thickness of the vertebra 3 is small enough that the magnets 15,16 attract through the bone wall and thus stabilize the auxiliary probe 14 relative to the main probe 1. This attachment is advantageous over a fixation with surgical threads in that it simplifies the operation surgical.
- the auxiliary probe 14 can fulfill several functions:
- the auxiliary probe 14 comprises a sensor 17 reacting to the presence of certain biological molecules in the cerebrospinal fluid by producing an electrical signal.
- the auxiliary probe 14 comprises electronic means 18 for converting this signal into digital data.
- the auxiliary probe 14 comprises a reservoir 19, provided with a membrane, for storing chemical compounds; a micromotor 20 cooperates with the membrane to selectively move it, which causes the expulsion of the chemical compounds in the spinal cord 7.
- electrodes 21 may impose a local potential on the axons of the spinal cord 7 in contact with the spinal cord 7. the electrodes 21.
- the transceiver D of the auxiliary probe 14 here comprises an infrared transmitter 22 and an infrared receiver 23 which communicate in a binary field with the infrared transmitter 10 and the infrared receiver 11 of the main probe 1.
- no wired connection n is necessary between the two probes to transmit the data generated by the electronic means 18 or to receive commands from the main probe 1.
- the supply of the auxiliary probe 14 is made wirelessly: according to a preferred device, a antenna 24 is in induction connection with the antenna 12 of the probe main 1.
- the electronic means 18 are adapted to condition the potential induced in the antenna 24 to a potential directly usable by the auxiliary probe 14. Here, this potential is preferably used to charge an on-board battery.
- the auxiliary probe must be miniaturized because of its implantation as close as possible to the spinal cord, a hypersensitive organ. Because of its size, the auxiliary probe is limited in autonomy and needs to be connected to a larger probe, here the main probe, to be fed regularly.
- the communication between the auxiliary probe 14 and the main probe 1, as well as between the main probe 1 and a transceiver remote from the main probe 1, is done by infrared radiation, one can use any other communication mode such as RFID communication or even, in the case of the main probe 1 and the remote transceiver, a communication with son.
- the main probe 1 had the same communication system to communicate with the auxiliary probe 14 and with the transceiver remote from the main probe, it will obviously be possible to propose a probe having two systems distinct communication.
- a system for measuring spinal cord activity 7 has been described in the main probe 1 by emission of electromagnetic waves in the infrared, other known techniques such as the emission of ultrasonic waves.
- the auxiliary probe is implanted inside the vertebra 3 to be in direct contact with the spinal cord 7, it will be more generally possible to implant the auxiliary probe in contact with any functional tissue.
