Abstract
The utility model provides an implanted electrical nerve stimulation system with a joint fixing device, which comprises an extension lead, wherein the extension lead is provided with a joint, and the extension lead is connected to an electrode via the joint. The implanted electrical nerve stimulation system is characterized in that the joint fixing device arranged at the joint is a flexible rectangular sheet and is provided with two or more holes which are spaced mutually. In the implanted electrical nerve stimulation system with a joint fixing device, the joint is fixed properly and can not move relative to the surrounding body tissues, thereby avoiding bringing discomfort to patients.
Description
Technical field
This utility model relates to a kind of implantable nerve electric stimulation, particularly relates to a kind of implantable nerve electric stimulation with joint fixture.
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, lead, extension wire and control device usually.Wherein, pulse generator is connected with extension wire, extension wire and then be connected to electrode by joint again, thereby with burst transmissions that pulse generator produced to electrode, so that nerve is carried out electricity irritation.
At present, the joint of extension wire can move with respect to bodily tissue on every side along with the motion of patient body, thereby produce friction with it owing to lack fixture, causes subject discomfort, even causes pain or other symptoms.
The utility model content
In order to prevent that implantable nerve electric stimulation center tap from moving with respect to bodily tissue on every side, this utility model provides a kind of implantable nerve electric stimulation with joint fixture.
According to a kind of implantable nerve electric stimulation with joint fixture of the present utility model, described implantable nerve electric stimulation comprises:
Extension wire, described extension wire has joint, and described extension wire is connected to electrode by described joint;
It is characterized in that:
Described joint is provided with the joint fixture, and described joint fixture is flexible rectangular thin plate, and described joint fixture is provided with spaced two or more holes.
Further, described hole can be counter sink.
Further, described joint fixture has sweep.
In the implantable nerve electric stimulation with joint fixture of the present utility model, joint is suitably fixed, not can with respect to around bodily tissue move and cause subject discomfort.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.In the accompanying drawing:
Fig. 1 is the sketch map of the implantable nerve electric stimulation of prior art;
Fig. 2 is the sketch map according to implantable nerve electric stimulation of the present utility model;
Fig. 3 is the axonometric chart according to implantable nerve electric stimulation center tap fixture of the present utility model;
Fig. 4 is the axonometric chart according to another embodiment of implantable nerve electric stimulation center tap fixture of the present utility model.
Reference numeral: pulse generator 1, extension wire 2, electrode 3, joint fixture 4, hole 5, sweep 6, screw 7.
The specific embodiment
Fig. 1 is the sketch map of the implantable nerve electric stimulation of prior art.With reference to Fig. 1, the implantable nerve electric stimulation of prior art mainly comprises pulse generator 1, extension wire 2 and the electrode 3 that implants, and is positioned at external control device.Pulse generator 1, extension wire 2 and electrode 3 are connected successively.Wherein, an end of electrode 3 is connected to extension wire 2 by joint.
At present, joint can move with respect to bodily tissue on every side along with the motion of patient body, thereby produce friction with it owing to lack corresponding fixture, causes subject discomfort, even causes pain or other symptoms.
Fig. 2 is the sketch map according to implantable nerve electric stimulation of the present utility model.Embodiment with reference to shown in Figure 2 has joint fixture 4 according to implantable nerve electric stimulation of the present utility model.By joint fixture 4, the joint of implantable nerve electric stimulation is fixed to patient's bone, thereby can not move with respect to bodily tissue on every side.
Fig. 3 is the axonometric chart according to implantable nerve electric stimulation center tap fixture of the present utility model.With reference to Fig. 3, joint fixture 4 is flexible rectangular thin plate, and it is provided with spaced a plurality of hole 5.Preferably, joint fixture 4 is made by the biocompatible material such as titanium.Preferably, the hole 5 of joint fixture 4 is set to counter sink, and its quantity can be set to two or more as required.
During installation, the joint of extension wire is pressed on patient's the bone, corresponding two holes 5 that screw 7 passes the joint both sides that are positioned at extension wire in the joint fixture 4 screw in patients' bone.Because the pliability of joint fixture 4, its middle part forms sweep 6 and extends through with the joint that holds extension wire, and the part of the joint both sides that are positioned at extension wire of joint fixture 4 then contacts with patient's bone applying under the effect of screw 7.Thus, the joint of extension wire is fixed reliably.
Fig. 4 is the axonometric chart according to another embodiment of implantable nerve electric stimulation center tap fixture of the present utility model.With reference to embodiment shown in Figure 4, the middle part of joint fixture 4 is formed with sweep 6 in advance.
More than the specific embodiment of the present utility model is described.Be illustrative for description of the present utility model herein, thereby scope of the present utility model 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 utility model or substitutive characteristics, can carry out other distortion or change the above-mentioned specific embodiment.
