Means for sealing a well bore and attaching a conduit

description

The invention relates to a device for closing an opening, particularly a bore hole in a wall, in particular in the form of a skull cap, as well as for fixing a line which passes through the opening (eg in a substantially axial direction). It is prior art to introduce diagnostic and therapeutic purposes leads into the skull of the patient. It may be electrical cables, hoses, or other lines. They allow the delivery of drugs for the treatment or the fluid discharge or the discharge of electrical signals from the brain or the stimulation of the brain with electrical signals. A subset of medical lines are so-called catheter. It is to tubes with one or more internal lumens with which body fluids are removed from the body or liquids such as medicines, can be introduced into the body. Another sub-group of medical leads are called electrodes. It is insulated cables with one or more conductors, which serve to discharge electrical signals from the body for diagnostic purposes, or the introduction of electrical signals for therapeutic purposes.

For the diagnosis and treatment of the brain such lines must each be passed through an opening or a hole in the bone of the skull and are then guided to the specific location in the brain where they can perform their function. Because of the tight space conditions in the skull and because of the small dimension of these lines, it is particularly important that the lines are fixed precisely so that they can fulfill their function permanently. A large part of these lines will remain permanently in the brain. The line is then moved away from the well under the skin along and connected to a unit that controls the supply and removal of substances or signals.

Illustrative of the subgroup of the catheter may be mentioned the so-called hydrocephalus shunt system here. In this case, the tip of the catheter is placed in one of the fluid-filled spaces of the brain. The other end of the catheter is connected to a pressure relief valve, a further catheter connects the relief valve to the abdominal cavity, so that excess cerebrospinal fluid is drained into the abdominal cavity. Illustrative of the subset of the electrodes may be mentioned the so-called deep brain stimulation unit here. In this case, the tip of an electrode is brought to a specific location in the brain. The other end of the electrode is connected to a pacemaker which generates certain pulses to the effect affect the brain that certain symptoms are ameliorated. Mention may be trembling with Parkinson's disease, which can be well treated with deep brain stimulation here.

In all these systems the exact fixation of the head of the line is required. Furthermore, it is desirable to seal the borehole, so that an optimal cosmetic result. The holes for the electrodes of the deep brain stimulation, and for the catheters of the hydrocephalus shunt valves are typically attached to the forehead of the patient, where they strike cosmetically at not optimum closure. Further, when the closure device applying spatially very irritated the thin skin at the front and in the worst case even pierced.

For closure of such holes of the type mentioned closing caps are known that are also equipped with means for fixing the pipe, thus enabling the fixing of the pipe. However, all such known caps have the disadvantage that they are not sure or firm enough hold the line and / or that they too apply because they are too thick, or the surface of the skull bone to far surpass so that the cosmetic result of , surgery is not adequately met even though the line fulfills her function. Especially when progresses the recovery in a patient moves the patient's attention and its environment from the actual disease that is indeed "cured" from, and focuses on the details of the treatment system. A cosmetically unsatisfactory packer, which yes is especially noticeable on the forehead, and perhaps even impressed crimson irritated, creates a substantial suffering in such cases and diminish the success of the treatment significantly. In addition, many of the diseases to be treated advanced age concern, so just in men by the receding hairline concealment of brushing over the skin level cap is difficult. That an insufficient fixation of the line that ends in a failure due to slippage, treatment success is not even given the sake of completeness it should be mentioned here.

The means for fixation of the conduit means are known in which the line is fixed by friction in a clamping device, so clamped and / or kinked. If it is in the line to a catheter, it can, for clamping or at least a reduction of the inner diameter and thus to a negative influence on the function. If it is in the line is an electrode, it may cause damage to the conductor. The isolation of such lines is preferably made of relatively soft materials to avoid mechanical irritation of the patient's tissue. Therefore, a cord is such a relatively sensitive to mechanical damage and can easily be damaged by clamping and kinking.

are known borehole closure caps which consist of an annular insert which is fixed in the borehole, and further comprise a cover which is clamped in use or otherwise fixed. In this case, an opening for the passage of the line is mounted between the insert and the lid. The opening has a cross section which is smaller than the line to be fixed, so that the line is firmly clamped in fixed state. the risk of damage or constriction is also here if the clamping force is high enough given. If the clamping force is not high enough, so that the line is not limited by them, the fixation is unsatisfactory. Furthermore, in the known systems, the lid is designed such that it is at least partially placed onto the insert. He towers above the surface of the skull considerably and thus affect the cosmetic result. An example of such a system according to the prior art is known from document US4328813 Bray.

Fig. 9 shows an alternative detail of FIG. 2.

Figures 2 to 7 show an embodiment of an inventive

Means for closing an opening 1 (borehole). The opening 1 and the borehole 1 can in particular be designed as a stepped opening or bore, in which the inner diameter of the opening or bore 1 1 inwardly reduced stepwise. The device also serves for fixing a line 3, which is guided into the borehole 1, in a wall 2 (skullcap) has been introduced.

The device comprises a ring-shaped slotted insert 4, which is fixed in the opening 1 and the borehole. 1 This insert 4 has an outer surface 5 (in particular a sawtooth with circumferential teeth 5a has) 6 (for example, hole) and a slot 6a which interrupts the annular structure of the insert 4, so that the insert 4 is open annularly designed, a through opening , The fixated pipe 3 can therefore be placed over the slit 6a in the through hole 6 of the insert. 4 In the

Through hole 6 is arranged a first means 7 for clamping the line 3 (clip), which projects from the insert 4 in the through hole 6 and the first clamping force is so low that the line 3 is not damaged and is not constricted. Preferably generated by this first means 7 for clamping only the holding force for a ( "pulley-type") guide 8 or fixing means 8, which exerts on the principle of looping the actual fixation force to the line. 3 Further, a lid and means for closing 11 available, and which is fixed in the through hole 6 of the insert 4 and the respectively illustrating a second means for clamping together with the insert 4, which generates a second clamping force on the pipe 3, so that the exiting end of the line 3 in the guide track of the guide 8 (fixing means 8) is maintained. this second clamping force is preferably so low that the cross-section of the conduit 3 is not damaged and does not constricted.

The inventive solution is based in particular on the principle of

Looping (see FIG. 1), in which a line 3 or a rope around a drum (here guide 8) is wound. According to the equation, the force Eytelwein S2 is the force with which the tail end of a cable or line 3 can be maximally loaded, without slipping it:

S2 = S1 xe w

S1 is the "holding power" at the incoming end of the rope,

e is Euler's number 2.718 ..., a transcendental real number which the base of the (natural) exponential function (commonly known as: e-function) is formed.

μ is the coefficient of friction is φ the wrap.

From the equation it is seen that the maximum transmittable force S2 does not depend on the diameter of the drum or the guide. 8 Since the frictional pressure (force per unit area) on the cable or the line 3 with increasing

drum diameter is smaller since the abutting surface becomes greater, the drum may be dimensioned so that the cable (line 3) is not damaged by friction pressure and that the transmitted force is sufficiently large by appropriate selection of the wrap angle.

The principle of looping is advantageously applied to winches and winches on sailing ships. taken care must only be that the cable (line 3) is not jump off of the drum. This is done manually on the winch.

Transferred to the conditions in the fixation of a pipe 3 in a device for closing an opening (hole), the drum or the guide 8 is dimensioned in particular with a large diameter as possible only by the diameter of the opening 1 and of the wellbore 1 is limited. The holding force F1 generated by the first means for terminals 7, and

Avoiding the Abspringens the line 3 is preferably fixed by the lid 1 1, which in the insert 4 is preferably used together with recesses 19, 20 the second means for clamping. Since the force for preventing the Abspringens in turn can be relatively small, the cross-sectional reduction is by the second means 11, 19, 20 for clamping in turn is so small that the line 3 is not damaged and no constricted function is reducing.

Fig. 2 shows in connection with Figures 3 to 7, the inventive device (also referred to as a cap) to the to be closed opening (hole) 1. In the well 1 in the wall or skullcap 2 is the line 3, which in the wellbore 1 extends substantially in the axial direction. Furthermore, not yet introduced into the borehole 1, the slotted insert 4 is shown having an outer side 5 for abutment against a peripheral wall of the bore 1 and a through hole. 6 The clip 7 serving as a first means for clamping the conduit 3. The conduit 8 with a curved bearing surface is the periphery of the opening for the cable 3 of the generation of the

Umschlingungsreibungskraft when the line 3 is inserted respectively into the guide and rests against the contact surface and thereby a defined

Enclosing angle comprises (a winding angle of 360 ° would thereby a full turn of the line 3 on the guide 8, respectively). In the illustrated embodiment of the invention the wrap angle is approximately 190 degrees and the guide 8 is formed in particular "pulley segment-like manner". The openings (for example holes) 9 and 10 of the insert 4, in particular as

Passage openings are adapted to accommodate a terminal serve (mosquito terminal o. Ä.) For compressing, so that the diameter of the insert 4 is reduced and the insert 4 can be pushed into the borehole 1. , Is also not yet placed on the insert 4, the cover 1 1 shown, which is equipped with a slot 12th Further, the lid 11 is also provided with two openings (for example holes) 13, 14, in particular in the form of
