Abstract
The invention discloses an electrode contact structure of an implantable electrical nerve stimulator. The electrode contact structure comprises a platinum-iridium alloy spiral which is made from a platinum-iridium alloy wire, wherein a small spiral line is fixedly connected to one end of the platinum-iridium alloy spiral, so that an electrode for transmitting an electric stimulation signal is formed; the joint of the platinum-iridium alloy spiral and the small spiral line is covered by silica gel, so that a butterfly wing-shaped fixed part; and in order to facilitate connection to and fixation with a stimulated part, the other end of the platinum-iridium alloy spiral is connected to a medical suture line which is provided with a medical suture needle. Through the structures, since the platinum-iridium alloy spiral and the small spiral line are connected, the electrode contact structure is sufficient in connecting strength and is capable of stably transmitting the electric stimulation signal. In addition, in the structures, the contact of the platinum-iridium alloy spiral can be connected to such stimulated parts as stomach, colon, heart and the like, and the phenomenon of separating in the peristalsis process of the stimulated part is avoided and the electric stimulation signal is transmitted stably.
Description
Technical field:
The present invention relates to field of medical device, in particular to a kind of embedded nerve stimulator electrode contacts structure.
Background technology:
Existing therapeutic medical nerve stimulator, platinum iridium alloy sheet or column body are directly applied usually as electrode contacts in the such as electrode wires tail end contact of Gastric electrical stimulation device, colon electrical stimulator and heart electric stimulating device etc. This scheme has following shortcoming:
1. platinum iridium alloy sheet or post are soft not, and the contact between implanting tissue coincide closely not.
2. platinum iridium alloy sheet or post and contact between implant into body tissue is fixing is difficult to operation or reliable not.
3. contact between platinum iridium alloy silk and implant into body tissue is abundant not. Platinoiridita screw contacts is that after avoiding the fracture of sub-thread taenidium, electrical signal interrupts by multiply and around generation spiral.
Summary of the invention:
In view of above-mentioned technical problem, the present invention provides a kind of embedded nerve stimulator electrode contacts structure. Adopt after this structure by the connection between platinum iridium alloy spiral and minor spiral line so that it is have enough strength of joint and electrical stimulation signal can be propagated stablely. In addition, adopt in this structure can also by platinum iridium alloy screw contacts and implant into body tissue by the connection of stimulation location, and can not be able to occur when being wriggled by stimulation location to depart from and can be stable propagate electrical stimulation signal.
The concrete technical scheme of the present invention is as follows:
Embedded nerve stimulator electrode contacts structure, comprise a platinum iridium alloy silk and make platinum iridium alloy spiral, it is characterized in that, by being fixedly connected with, minor spiral line forms the electrode propagating electrical stimulation signal in described platinum iridium alloy spiral one end, and the connection section silica gel of this platinum iridium alloy spiral and minor spiral line is coated makes the fixing portion of butterfly wing; The other end of described platinum iridium alloy spiral is for the ease of being connected with medical belt pin suture line with being connected and fixed by stimulation location.
In such scheme, the butterfly wing of both sides, described butterfly wing fixing portion is respectively equipped with the fixed in position hole that is convenient to stationary contact.
In such scheme, the cannula port end of the fixing portion of described butterfly wing and little silicone tube is tightly connected.
In such scheme, described platinum iridium alloy spiral be connected with minor spiral pressing and overcoat for the protection of kapillary.
In such scheme, described minor spiral line is built in the little silicone tube that portion fixing with butterfly wing is connected.
In such scheme, described platinum iridium alloy spiral forms contact by platinum iridium alloy silk by helically coiling mode.
In such scheme, described platinum iridium alloy spiral by multiply and forms screw contacts around mode by platinum iridium alloy silk.
In such scheme, described band pin suture line is for being sewn into implanting tissue by contact.
Compared with prior art, the screw contacts of platinum iridium alloy described in the present invention is by the effect of suture line and the butterfly dish wing, platinum iridium alloy screw contacts and stomach, colon or heart etc. are more reliable by the connection of stimulation location, electrical stimulation signal propagates more stability and safety, and position, contact is soft, with be combined by the tissue tight of stimulation location, can not again organization activity time produce pull and misplace. It does not have platinum iridium alloy silk so sharp-pointed, can not stab by stimulation location.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
Fig. 1 is the one-piece construction figure of platinum iridium alloy screw contacts structure of the present invention.
Fig. 2 is the structure iron of platinum iridium alloy spiral in platinum iridium alloy screw contacts structure of the present invention.
Fig. 3 is the structure iron in the fixing portion of butterfly wing in platinum iridium alloy screw contacts structure of the present invention.
Embodiment:
In order to the present invention is realized technique means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the present invention further.
As shown in Figure 1, Figure 2 and Figure 3, embedded nerve stimulator electrode contacts structure of the present invention, it mainly comprises a platinum iridium alloy silk and makes platinum iridium alloy spiral 1. Wherein, platinum iridium alloy spiral 1 one end forms the electrode of propagation electrical stimulation signal by being fixedly connected with minor spiral line 6. Certainly, this platinum iridium alloy spiral 1 and minor spiral line 6 can by pressing or be welded to connect and one, overcoat for the protection of kapillary (not shown). The above-mentioned kapillary mentioned is existing conventional structure, therefore does not repeat. In addition, this platinum iridium alloy spiral 1 makes the fixing portion 3 of butterfly wing with the connection section silica gel of minor spiral line 6 is coated. The butterfly wing of both sides, this butterfly wing fixing portion 3 is respectively equipped with a fixed in position hole 31, and is sealedly connected on port 32 with little silicone tube. Minor spiral line 6 is built in the little silicone tube 2 that portion 3 fixing with butterfly wing is connected. In addition, the other end of platinum iridium alloy spiral 1, for the ease of being connected and fixed with by stimulation location, is connected with the suture 4 with medical sutures pin 5.
This electrode contacts structure is when reality uses, medical sutures pin 5 is fitted fixing for platinum iridium alloy spiral 1 through implanting tissue stimulation location by traction suture 4, simultaneously in sewing process, suture 4 also makes the electric shock of whole electrode to be connected better with by stimulation tissue through two fixed in position holes 31 in the fixing portion 3 of butterfly wing. And the platinum iridium alloy spiral 1 in structure is because it becomes winding screw shape, this position organ can not be caused and stab or wear damage, reduce the discomfort of sufferer.
More than show and describe the ultimate principle of the present invention and the advantage of main characteristic sum the present invention. The technician of the industry should understand; the present invention is not restricted to the described embodiments; the principle that the present invention is just described described in above-described embodiment and specification sheets; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.
