Abstract
The present invention relates to an in-vivo implantation stimulator which comprises a stimulation electronic system composed of electronic components and an integrated circuit. The invention is characterized in that a flexible bendable folding film which has a thickness of 0.1mm-0.2mm is adopted as a substrate. The substrate is printed with a metallic circuit as a current substrate film. The circuit and components are pressed and welded on the inner layer and outer layer of substrate film. The circuit substrate film has a cylinder shape. The electronic components are arranged between two pie-shaped substrates crossly. The two pie-shaped substrates have a cylinder shape after combination. The folding surface of whole assembly is wholly coated with a water-proof and moisture-proof coating after the electronic components are installed on the substrate. The stimulation electronic system and the substrate are contained in the titanium casing which is made of pure titanium. The titanium casing is wholly covered with medical adhesive. The invention adopts a novel material and a novel structure for greatly reducing the thickness of stimulator, arranging and installing the components more flexibly, and facilitating implantation into human body.
Description
Technical field
The present invention relates to the stimulator in the nerve stimulation device of therapeutic medical implant into body, particularly a kind of stimulator for implantation in vivo.
Background technology
At present, human body stimulator (body is implanted into system) adopts electronic devices and components and integrated circuit to form a complete stimulation electronic system, all adopts pottery or hard non-metallic material as the circuit substrate that components and parts are installed usually.The human body stimulator for implantation is made up of integrated circuit and electronic component, it is included in the housing of titanium TA1 or ceramic material, form independently complete body stimulating system, an end that connects the metal electrode bundle on the substrate, the other end of electrode contacts with feature organization in the body or links to each other, like this, and its inner extraction electrode, export neuroactive electric excitation signal or electric current, reach the effect of treatment and restore funcitons.
Because the stimulator in the nerve stimulation device of all kinds of medical treatment of implant into body, be embedded in the skeleton or cavity tissue at each position of human body, consider that from the anatomy of human body the stimulator installation position is limited, and even be specific, so the volume (physical dimensions such as thickness, diameter) of the stimulator that is used for human body there is special requirement.
But,, all be to adopt epoxy resin board, two kinds of base materials of ceramic substrate basically as interplantation stimulator circuitry substrate from the domestic and international content of reporting.Like this, because the reason of material, the thickness of substrate and the density of cloth spare are all not ideal enough.And, showing that from the human dissection principle implant (stimulator) volume, one-tenth-value thickness 1/10 are big more, difficulty can take place in the position of its placement during operation, can produce danger when serious.
Summary of the invention
The objective of the invention is to, for overcoming above-mentioned deficiency of the prior art, thereby provide a kind of ultrathin structure stimulator for implantation in vivo.
For achieving the above object, stimulator for implantation in vivo of the present invention, comprise: the stimulation electronic system of forming by electronic devices and components and integrated circuit, it is characterized in that, adopting thickness is that 0.1 millimeter～0.2 millimeter flexible folding film is as substrate, print metallic circuit on the described substrate as the circuit basement membrane, circuit and components and parts coining are welded on the ectonexine of basement membrane.
As a kind of improvement of the present invention, described substrate employing high-low temperature resistant, the engineering plastics thin film that withstand voltage properties is good.
As another improvement of the present invention, it is conjuncted that described circuit basement membrane is circle, and described electronic devices and components arranged crosswise is in the centres of two circle basivalvulas, and two round basivalvulas are rounded body after altogether.
As another improvement of the present invention, after described electronic devices and components were installed on the substrate, amounting on the face of whole assembly wholely applied waterproof and dampproof coating, and row is amounted to again.
As another kind of improvement the of the present invention, described stimulation electronic system and chip holding thereof are in the titanium shell that pure titanium is made.Adopt titanium (TA1) as containing material (stimulator shell), reach the ideal human-body biological compatibility.Further, the outer whole medical glue that covers of described titanium shell is to realize curing, buffer protection.
The invention has the advantages that the present invention adopts a kind of new material and structure, it is thin that the thickness of stimulator is greatly changed, and components and parts are arranged and installed more flexibly, help human body and implant.
Show that from the human dissection principle implant (stimulator) volume is the smaller the better, Bao Yueyou more, its one-tenth-value thickness 1/10 is particularly important, otherwise during operation, difficulty can take place in the position of its placement, can produce danger when serious.The structure of embedded nerve stimulator provided by the present invention has solved above problem, can accomplish the little ultrathin structure of its stimulator volume.
Description of drawings
Fig. 1 is the sketch map after the substrate of stimulator for implantation in vivo of the present invention launches.
Fig. 2 is the sketch map after the amounting to of stimulator for implantation in vivo of the present invention.
Fig. 3 is the cut-away view after the stimulator for implantation in vivo of Fig. 2 is amounted to.
The specific embodiment
Further describe stimulator for implantation in vivo of the present invention below in conjunction with accompanying drawing.
As Fig. 1～shown in Figure 3, the present invention adopts the substrate (high-low temperature resistant, the engineering plastics thin film that withstand voltage properties is good) of flexible folding film, print metallic circuit above, thickness adopts 0.1 millimeter to 0.2 millimeter (mm) thick, as the circuit basement membrane, circuit and components and parts coining are welded on the ectonexine of basement membrane.It is conjuncted that its basement membrane is designed to a circle, as shown in Figure 1, just becomes a rounded body altogether, as shown in Figure 2.Its electronic devices and components are placed in the centre of two circle basivalvulas, but arranged crosswise, and thickness reduces not to the utmost, and has saved its space greatly, and the volume of interplantation stimulator, thickness are greatly improved, and has reached extra-thin structure.
Claims (6)
1, a kind of stimulator for implantation in vivo, comprise: the stimulation electronic system of forming by electronic devices and components and integrated circuit, it is characterized in that, adopting thickness is that 0.1 millimeter～0.2 millimeter flexible folding film is as substrate, print metallic circuit on the described substrate as the circuit basement membrane, circuit and components and parts coining are welded on the ectonexine of basement membrane.
