Definitions
- the invention relates to a device for measuring brain parameters according to the preamble of claim 1.
- Such a device is known from DE 102 39 743 Al.
- Central to such brain parameter sensors is the fixed and permanently stationary seat of the sensor unit on the cranial bone. Any relative movement of the brain parameter sensor to the brain tissue must be prevented after implantation in order to avoid brain damage.
- the attachment of the sensor unit to the cranial bone is solved in the known brain parameter sensors either by a rather complex attachment technique or is unsatisfactory in terms of securing against relative movement.
- an unobtrusive attachment of the sensor unit to the cranial bone can be achieved if the passage of the sensor unit through the cranial bone is simultaneously used as an attachment site.
- the self-tapping external thread which leads to a permanent, safe and uncomplicated hold of the sensor unit on the cranial bone, serves this purpose.
- An undesirable Relative movement of the sensor unit to the brain tissue after implantation is then reliably prevented. Elaborate additional attachment measures can be omitted.
- An external thread according to claim 2 leads to a compact device. At the same time an undesired displacement of the external thread relative to the sensor unit is reliably prevented.
- An external thread according to claim 3 solves a further central problem in the arrangement of an implantable by means of passage through the skull bone measuring device, namely the secure sealing of the sensor unit against the skull bone, so that leakage of liquid or brain tissue is reliably prevented.
- This sealing takes place in the arrangement with a sealing external thread directly in the region of the implementation, so that the requirements for a downstream seal in the proximal sensor section are reduced or such a downstream proximal seal can be omitted entirely.
- An external thread according to claim 4 is inexpensive to manufacture.
- An external thread according to claim 5 enables a functional separation of the various functions of this external thread, namely cutting on the one hand and sealing on the other.
- a stop according to claim 6 allows a defined screwing the device.
- An embodiment of the invention will be explained in more detail with reference to the drawing.
- the single FIGURE shows a section through a head section of a patient with a device for measuring brain parameters.
- the device, generally designated 1, for measuring brain parameters comprises a catheter sensor unit 2, which is implanted in the parenchyma and / or the ventricles in a minimally invasive manner. At its distal end, that is, where the catheter sensor unit 2 protrudes into brain tissue or CSF 2a of the patient, the catheter sensor unit 2 has a pressure sensor 3 and a temperature sensor 3a. Proximally, the catheter sensor unit 2 is fixed to a cranial bone 4 of the patient.
- a proximal peripheral portion of the sensor unit 2 has a self-tapping external thread 5. The latter generates when cutting into the skull bone 4 in this one to the external thread 5 complementary internal thread.
- the external thread 5 is an integral part of the sensor unit 2, so is not one of this separate component.
- the external thread 5 has a sealing coating, not shown in the drawing, so that the sensor unit 2 is sealed against the cranial bone 4 via the external thread 5. CSF or tissue can therefore not escape from the brain at the site of the implanted sensor unit 2.
- the device 1 further includes a base plate 7 with a through-hole 8, through which the catheter sensor unit 2 is passed and which is aligned with the internal thread 6.
- a proximal head part 9 abuts on the grand plate 7 via an expansion stage 10.
- the head part 9 of the sensor unit 2 thus has a significantly greater circumference than the catheter section of the sensor unit 2.
- the extension step 10 represents a stopper of the sensor unit 2, which terminates the screw-in depth of the latter, at a proximal end section, namely the head part 9.
- an additional proximal seal 11 is arranged, which is inserted into a sleeve 12 of the head part 9.
- the seal 11 seals the sensor unit 2 against the skull bone 4 via the base plate 7 from.
- On grand D ichtungs effect of the outer fabric 5 can be dispensed with the seal 11 also.
- Pressure can be exerted on the seal 11 with the aid of a screw cap 13, which is screwed into the sleeve 12 from above.
- the sensor unit 2 Via a micro connector 14 and a signal line 15, the sensor unit 2 is connected to an electronics unit 16 shown in several parts in the drawing.
- the grand plate 7 is fixed by screws 17 on the skull bone 4. Laterally, the grand plate 7 in the drawing upwardly projecting threaded bolt 18. About this a device 1 in the drawing upwards covering semiflexible cover 19 is inserted at the edge. The cover 19 is peripherally clamped between the grand plate 7 and fastening nuts 20 which are screwed onto the threaded bolt 18. The cover 19 protects the device 1 as a whole. The cover 19 is covered by the scalp 21.
- the external thread 5 is screwed. Due to the self-tapping action of the external thread 5, the internal thread 6 is formed from the bore in the cranial bone 4. The screwing procedure is continued until the sleeve 12 bears against the base plate 7. Finally, after unscrewing the screw cap 13, nor the wiring with the provided on the base plate 7 modules of the electronic unit 16. Subsequently, the cover 19 is attached and the first removed scalp 21 again stretched over the device 1. This is then ready to measure the corresponding physiological parameters brain pressure and brain temperature on the pressure sensor 3 and the temperature sensor 3 a ready.
