Abstract
The invention provides an extension lead for an implantable neuroelectric stimulation system, which comprises one or more inner leads and an insulator, wherein the inner leads are wrapped by the insulator. The extension lead is characterized in that the inner leads are formed in a continuous spiral shape which extends to the full-length range. When the extension lead for the implantable neuroelectric stimulation system is used, the dilatability is improved further, so the extension lead can adapt to the large-range motion of bodies and heads of patients without causing discomfort of the patients. Meanwhile, the risks of invalidation such as loosing, breakage and the like of connectors due to the pulling of the lead are reduced.
Description
Technical field
The present invention relates to a kind of implantable nerve electric stimulation, particularly relate to the extension wire of implantable nerve electric stimulation.
Background technology
Nerve electric stimulation has important effect in maladjusted nervous system treatment and nerve injury rehabilitation.The implantable nerve electric stimulation by in human body such as nervus motorius, sensorineural specific neural place implant electrode, discharge high-frequency electrical stimulation, stimulating, thereby make function of human body return to the state of normal operation for specific nerve.At present, the implantable nerve electric stimulation mainly comprises implanted brain deep electricity irritation (DBS), and the implanted cortex stimulates (CNS), implanted spinal cord stimulation trial system (SCS), implanted sacral nerves electric stimulation (SNS), implanted vagus nerve electric stimulation (VNS) or the like.
Known implantable nerve electric stimulation mainly comprises pulse generator, electrode, extension wire and control device usually.Wherein, pulse generator is connected with extension wire, extension wire and then be connected to electrode again, thereby with burst transmissions that pulse generator produced to electrode, so that nerve is carried out electricity irritation.
The extension wire of known implantable nerve electric stimulation generally includes one or more inside conductor, and each inside conductor has spaced a plurality of spiral part.The patient's body motion time can produce the pulling effect to extension wire, and the purpose of described spiral part is to extension wire provides Telescopic, makes extension wire can be adapted to the patient's body motion and can not cause subject discomfort.
But in the design of existing extension wire, the dilatability that spaced a plurality of spire branch can provide is not enough for patient's body kinematics by a relatively large margin.When patient's body, head movement have bigger amplitude, still can cause subject discomfort.Pull failure risks such as the union joint that causes gets loose, fracture simultaneously because of lead also higher.
Summary of the invention
In order to improve the dilatability of extension wire, the invention provides a kind of extension wire that is used for the implantable nerve electric stimulation.
According to a kind of extension wire that is used for the implantable nerve electric stimulation of the present invention, described extension wire comprises:
One or more inside conductors;
Insulator, described insulator coats described inside conductor;
It is characterized in that:
Described inside conductor forms and extends the successive spiral-shaped of its length range.
Further, a plurality of inside conductors can form successive spiral-shaped and constitute the inside conductor group together.
Further, described extension wire can include one or more inside conductor group.
Further, described inside conductor can comprise the skin of inner core and the described inner core of coating, and described inner core can be made by the material of low-resistivity, and described skin can be made by the material of high mechanical properties.
The extension wire that is used for the implantable nerve electric stimulation according to the present invention has further improved dilatability, can adapt to the body kinematics by a relatively large margin than the patient, can not cause subject discomfort.Reduced simultaneously and pullled failure risks such as the union joint that causes gets loose, fracture because of lead.

The specific embodiment
Fig. 1 is the sketch map of extension wire of the implantable nerve electric stimulation of prior art.With reference to Fig. 1, the extension wire 1 of the implantable nerve electric stimulation of prior art generally includes insulator 2 and inside conductor 3.Insulator 2 coats inside conductor 3.
Each inside conductor 3 can have spaced a plurality of spiral part 4.The purpose of spiral part 4 is to extension wire 1 provides Telescopic, makes extension wire 1 can be adapted to patient's body, head movement and can not cause subject discomfort.Reduced simultaneously and pullled the union joint that causes because of lead and get loose failure risks such as fracture.
In addition, insulator 2 is made by telescopic material, and for example polyurethane (polyurethane), silicone rubber (silicone) etc. are with flexible with inside conductor 3.
But 4 dilatabilities that can provide of spaced a plurality of spiral parts are not enough for patient's health by a relatively large margin, head movement.When patient's body, head movement have bigger amplitude, still can cause subject discomfort.
In order to improve the dilatability of extension wire 1, the invention provides a kind of extension wire that is used for the implantable nerve electric stimulation.
Fig. 2 is the sketch map that is used for the extension wire of implantable nerve electric stimulation according to of the present invention.Be arranged to extend the successive spiral-shaped of its length range at the inside conductor 3 of extension wire shown in Figure 21, that is, inside conductor 3 is successive spiral-shaped in its length range.Compared to spaced a plurality of spiral parts, the successive spiral that extends its length range possesses bigger dilatability, thereby provides bigger dilatability for extension wire 1.
Inside conductor 3 can the low wire rod of resistivity be made by the mechanical strength height.For example, this wire rod can comprise inner core and coat the skin of inner core, and inner core can be made by the material such as the low-resistivity of silver, and outer can making by the material such as stainless high mechanical properties, thereby make inside conductor 3 have the intensity height and the low characteristics of resistivity.Thus, compared to inside conductor with spaced a plurality of spiral parts, can be longer though extend the successive spiral-shaped inside conductor length of its length range, its resistivity can meet the demands fully.
Fig. 3 is the sketch map according to the inside conductor group of the extension wire of implantable nerve electric stimulation of the present invention.In extension wire 1, can form successive spiral-shaped and constitute the inside conductor group together by a plurality of inside conductors 3.For example, in the embodiment shown in Fig. 3, form successive spiral-shaped and constitute the inside conductor group together by four inside conductors 3.
Fig. 4 is the axonometric chart according to an embodiment of the extension wire of implantable nerve electric stimulation of the present invention; Fig. 5 is the cutaway view of the embodiment of extension wire shown in Figure 4.In the embodiment of Fig. 4 and extension wire 1 shown in Figure 5, extension wire 1 has four groups of inside conductor groups, and each inside conductor group is then formed successive spiral-shaped and constitute together by four inside conductors.
More than the specific embodiment of the present invention is described.Be illustrative for description of the invention herein, thereby scope of the present invention should not be limited to the above-mentioned specific embodiment.It will be apparent to one skilled in the art that under the situation that does not break away from purport of the present invention or substitutive characteristics, can carry out other distortion or change the above-mentioned specific embodiment.
