Implanting needle and implanting method of flexible implantable bio-sensor and photoelectric device

Abstract

The invention discloses an implanting needle and an implanting method of a flexible implantable bio-sensor and a photoelectric device. On the basis of the design of the implanting needle of variable sectional dimensions as well as design of the flexible implantable bio-sensor and the photoelectric device which are matched in a mode of being perforated in the top ends, the front end of the implanting needle adopts a variable cross section that in gradual or sudden change; the tops of the flexible implantable bio-sensor and the photoelectric device are provided with matching holes, so that onlythe front end of the implanting needle can run through the holes, the variable cross section is limited in position and the sensor and the device are supplied to designated positions in biological tissues; and after the implanting needle is withdrawn, the sensor and the device, which are provided with leads, are kept in the biological tissues, so as to complete detection and treatment functions inthe next step. The implanting needle provided by the invention is simple in structure, convenient to make, low in cost, light in injury to biological tissues and precisely controllable in implantingposition. In addition, the implanting method provided by the invention, just by changing the dimensions of the implanting needle, is applicable to flexible implantable bio-sensors and photoelectric devices of various biological tissues; therefore, the implanting method is broad in application scope.

Description

technical field [0001] The invention relates to an implant needle for a flexible implantable biosensor and a photoelectric device and an implantation method thereof, which can be used for implanting a flexible implantable biosensor and a photoelectric device in a biological tissue. The implant needle has a simple structure and is easy to prepare. Convenience and low cost; the implantation process is easy to operate and causes little damage. Background technique [0002] The continuous acceleration of the pace of modern life makes people often in a state of high pressure physically and mentally, and neurological diseases such as depression and epilepsy have increased significantly; at the same time, the global population is gradually aging, and diseases such as neurodegenerative diseases and muscle atrophy are gradually increasing and becoming a big burden on society. The traditional treatment of nervous system, muscle tissue and other diseases mostly adopts a combination of...

AI Technical Summary

Problems solved by technology

[0009] In general, existing implantable methods for flexible implantable biosensors and optoelectronic devices each have their own limitations

[0010] First, the disadvantage of the implantation method based on increasing the thickness of the device is that the size of the device is increased, the trauma to the biological tissue is greater, and it is not suitable for some biological tissues with a higher modulus such as muscle

At the same time, the mismatch between the modulus of the hard carrier and the biological tissue will cause severe mechanical damage and inflammatory response

[0011] Second, the disadvantage of the implant method based on degradable bio-coating is that the coating process is complicated, the coating thickness cannot be precisely controlled, and it is not suitable for some biological tissues with high modulus such as muscle

[0012] Third, the implant method based on hard carriers has the disadvantages of complex carrier processing, difficult bonding process, and high cost

In addition, the decomposition of the adhesive takes a long time, and the hard carrier remains in the tissue during this period, which will cause a certain degree of inflammatory response
