1 is a perspective view showing a medical body waste removal collector using a mesh attached to the full-function functional polymer according to the present invention, Figure 2 is a side portion of the medical waste removal collector for medical use using a mesh attached to the full-function functional polymer according to the present invention. 3 is a cross-sectional view illustrating a blood vessel insertion operation of a medical waste removal collector for medical treatment using a mesh attached to a full-function copper polymer according to the present invention.

As shown, the waste removal collector 200 according to the present invention has a cylindrical shape of the body portion 110 and the body portion 110 of the size that can be introduced into the blood vessel 10 of the bio-friendly tube material A collection drive unit 120 is formed at the front to collect the waste 20 so that a mesh 122 made of a biocompatible photoresist is attached between the circularly arranged full functional dynamic polymer (IPMC) 124 and a full functional homopolymer. Radial expansion and contraction is performed by applying voltage to 124.
The photosensitive agent is a polymer that is sensitive to light as being SU-8.

In addition, the electric wire 130 is connected to the active collection drive unit 120 to supply power to the inside of the body part 110, and the collection drive unit 120 is configured as a circular tube inside the body part 110. It consists of a waste removal collector 200 consisting of a suction suction pipe 140 for sucking and collecting the soft waste 20 is not collected in the mesh 122 of the.

The waste removal collector 200 is disposed as a human blood vessel 10 along with a surgical tool (not shown) to be disposed of by the physical removal of the waste 20 having various sizes and shapes ( 20 is to suction and remove various kinds of waste 20 to the suction pipe 140 in the mesh 122 and the body portion 110 of the collection drive unit 120 to be transferred to the outside of the body.

As such, the waste removal collector 200 is a bio-friendly intelligent waste removal collector 200 based on a full-featured polymer (IPMC) 124 to directly remove the waste 20 generated in the human body in vitro. In order to improve the performance of the full-function dynamic polymer (IPMC) 124, which is generated when the waste is collected, a composite of a polymer (Nafion) and carbon nanotube (CNT) (34) is manufactured in a new method. Using this to produce a full-function dynamic polymer (124).

The full-featured polymer (IPMC) 124 of the collector driving unit 120 configured in the waste removal collector 200 may be replaced with polypyrrole and polyaniline, and includes all the full-featured polymer 124, polypyrrole, and polyaniline. Collectively, it can be called full functional homopolymer (EAP).

That is, a full functional dynamic polymer (IPMC) 124 and polypyrrole, which are produced by mixing a Nafion film (Nafion flim) layer 32 with a carbon nanotube (CNT) 34, which is a functional (electrically conductive) material, It is made of a polymer driven by electric application to each polyaniline to be a full functional homopolymer (EAP) used in the collection drive unit 120. {Full functional dynamic polymer = full functional homopolymer> IMPC = polypyrrole = polyaniline}

Thus, the full-function dynamic polymer (IPMC) 124 has a number of advantages that are suitable for use as the material of the collection drive unit 120 proposed in the present invention, but when the current is applied deformation of the resistance according to the change of the shape There is a problem that the driving force is reduced due to the change. In order to solve this problem, in the present invention, carbon nanotubes, which are functional (electrically conductive) materials, are formed on the Nafion flim layer 32, which is a material of the full functional copper polymer (IPMC) 124. (34) to produce a composite by adding a method different from the conventional methods, and using this complex to produce a full-function dynamic polymer (IPMC) 124 to produce a full-functional dynamic polymer (IPMC) ( 124) mechanical and electrical properties have been changed.

At this time, the full functional dynamic polymer (Ionic Polymer Metal Composite, IPMC) 124 is one of the full functional homopolymer (EAP) that is being studied as a material for biomimetic engineering, etc. on both ends of Nafion, a commercial polymer of Dupont, USA. It has a structure having a metal electrode.

Here, Nafion is a polymer developed by Dupont in the United States and is most known as the main material of fuel cells. In addition, it is a material used in various studies and has a thin film having a specific thickness (50 to 180 μm). There are two forms, the membrane form and the dispersion. A thin membrane is generally used to fabricate a full functional copper polymer (IPMC) 124, but a Nafion solution is used to produce a Nafion film layer 32 having a desired thickness. In addition, a Nafion film layer 32 may be manufactured and used.

Carbon nano-tube 34 is a material in which a hexagon consisting of six carbon atoms is connected to each other to form a cylindrical (tube) shape. It is a new material that attracts attention from many researchers because it provides excellent mechanical and electrical properties that could not be expected with existing materials with only a small amount of ~ 5wt%.

The waste removal collector 200 is a bio-competible collection drive unit 120 and each collection drive unit 120 made using a cylindrical body 110 and a full-featured polymer 124. It consists of a suction tube 140 in the form of a suction tube for removing a large amount of waste and the structure of the network 122 connected by a photo-resist (Photo-resist).

As such, the body portion 110 of the waste removal collector 200 is formed in a cylindrical shape of a bio-friendly tube material, the body portion 110 is easily processed using a commercial material harmless to the human body, such as a surgical tube Make it possible.

In addition, the collection drive unit 120 of the waste removal collector 200 is to collect the waste 20 in front of the body portion 110 is a full-function dynamic polymer in a circular array of mesh 122 made of biocompatible photosensitizers It is attached between 124, and spreads and retracts radially by the application of voltage to the full-function copper polymer 124.

The collection drive unit 120 is made of a full-featured polymer 124 and is folded to the trunk 110 until it approaches the lesion by moving with a surgical tool (not shown). When the operation is started, the full-featured polymer 124 with the mesh 122 is designed to be unfolded so that the waste removal collector 200 is easily accessible to the lesion, and at this time, the degree of each collection driving unit 120 is unfolded. Alternatively, it is possible to control and maintain the position of the waste removal collector 200 in the cross-sectional direction in the blood vessel 10.

Here, the waste removal collector 200 is put into the vessel 10 together with the surgical tool to control and maintain the position of the waste removal collector 200 in the vessel 10.

That is, when the same amount of voltage is applied to the collection drive unit 120 made of the full-featured polymer 124 circularly arranged around the torso 110 of the waste removal collector 200 by the electric wire 130, The displacement driving unit 120 is located radially in the center of the vessel 10 while pushing the inner circumferential surface of the vessel 10 due to the displacement of the size, and the acquisition driver 120 maintains driving by applying a DC-bias. Through the action of pushing the wall of the elastic vessel 10 is to maintain the position of the waste removal collector 200.

In this case, the DC-bias means to give a voltage or current to the DC to operate the transistor in the most optimal state.

As such, it is designed to apply a voltage to the full-featured polymer 124 of the collection driver 120 formed in the waste removal collector 200 using one electric wire 130. In this case, the same is applied to each collection driver 120. Positive voltage is applied to cause displacement of the same magnitude.

In this case, when the electric wire 130 of several strands is connected to each full-function copper polymer 124 of the waste removal collector 200, and voltages of different sizes are applied to the plurality of full-function copper polymer 124, respectively, The collection drive unit 120 may cause displacements of different sizes.

When the displacement is generated by applying a voltage to the waste removing collector 200 in the blood vessel 10, the collecting driver 120 is pushed to push the blood vessel 10 while the waste removing collector 200 is reacted. In this case, when the full-function polymers 124 of all the collection driving units 120 have the same size displacement, the waste removal collector 200 is located at the center of the blood vessel 10 (centering), DC-bias ( When the driving is maintained by applying a bias), the collection driving unit 120 may maintain the position of the waste removing collector 200 by pushing the elastic blood vessel 10 wall, and the collection driving unit 120 may be maintained. If the full-function dynamic polymer 124 has a different size of displacement, the waste removal collector 200 moves in the direction in which the small-functional displacement full functional polymer 124 is located. In the same principle, when the blood vessel 10 has a non-circular non-specific shape, it is possible to control the position of the waste removal collector 200 in the cross section by adjusting the displacement of the collection driving unit 120.

In addition, the full-function dynamic polymer 124 of the collection drive unit 120 is an electroactive polymer material having a relatively fast response speed even at a low driving voltage by forming a circular arrangement at a predetermined interval in front of the body portion 110.

The full-function dynamic polymer (IPMC) 124 of the collection drive unit 120 is driven by the application of electricity, there are various types such as polypyrrole, polyaniline, in addition to the full-functional dynamic polymer (IPMC) 124.

This, the full-function dynamic polymer (IPMC) 124 of the capture drive unit 120 is moved through the application of a voltage having a polarity, and when the drive voltage disappears to return to the original form and the passive method for driving again When a voltage having a polarity opposite to the applied voltage is applied, the return action can be controlled by an active method in which driving is performed on the opposite side.

In addition, the collection drive unit 120 is a cylindrical shape, such as the trunk portion 110 until the collection drive unit 120 using the full-featured polymer 124, which expands and contracts by application of voltage, approaches a lesion in the blood vessel 10. The waste removal collector 200 is easily accessible to the lesion by moving in a constricted form, and when the lesion is located on the lesion, a voltage is applied to the collection driving unit 120 in a radial manner.

At this time, the mesh 122 of the collection drive unit 120 is connected between the full-function dynamic polymer (IPMC) 124 circularly arranged at a predetermined interval in front of the body portion 110, as shown in FIG. Radially unfolded together with the full-function dynamic polymer (IPMC) 124 radially unfolded by the application of voltage, and the blood 10 is collected between the nets 122 and the large calcified waste products are trapped in the nets 122 It is discharged to the body in a state attached to the (122).

As such, the mesh 122 located between the full-featured polymer 124 uses the phenomenon in which the waste 20 is sandwiched between the mesh 122 in addition to the removal of the basic waste 20. In order to prevent a phenomenon in which blood 12 is sucked together when suctioning the waste 20 using the suction pipe 140 positioned in the waste 20 caught in the mesh 122, the waste 20 is caught in the mesh 122 until the collection is completed. When the full-featured polymer 124 of the collection drive unit 120 that has been unfolded after the collection is completed, the waste removal collector 200 is discharged to the outside in the state in which the waste 20 is hung on the mesh 122. The waste 20 that was hanging on the net 122 is also removed.

In addition, the mesh is a net-shaped structure manufactured by using the bio-sensitive light-sensitive molecules between the collection drive unit 120 is a waste of various sizes, such as when the surgical tool is physically treated to a specific disease, such as chronic complete stenosis When a lot of this instant occurs, it is to be able to collect the waste of various sizes, at this time, the waste 20 between the capture drive unit 120 and each full-function polymer (124) is caught in the net 122. By directly removing the waste 20 in the human body by using the blood 10 can be prevented to be sucked together.

In addition, the suction pipe 140 configured to suck and collect the soft waste 20 which is not collected by the net 122 of the collection driving unit 120 is formed by a circular pipe inside the body part 110. exist.

The suction pipe 140 removes a large amount of waste material 20 by inhaling the waste material 20 which is small in size and flows into the suction pipe 140 located on one side of the waste material while being introduced into the waste removal collector 200. It is.

As such, the amount of the waste 20 generated according to the type of the disease and the patient in the situation that there is a limit of the amount of waste 20 collected due to the limitation of the size of the waste removal collector 200 entering the blood vessel 10. Since the amount of waste products 20 that are different from each other is also very large compared to the limit of the amount of wastes that can be collected, a large amount of waste materials (suction tube) 140 is disposed inside the waste removal collector 200. 20) can also be removed.

In addition, Figure 4 is a process diagram showing a method of manufacturing a full-functional dynamic polymer of the in-body waste removal collector for medical treatment using a net attached to the full-functional copper polymer according to the present invention, Figure 5 is a state diagram for the process diagram of Figure 4 in accordance with the present invention to be.

As shown in the drawings, a method for producing a full-functional dynamic polymer that is operated by the electrical application of the medical waste removal collector in the body using a mesh attached to the full-functional functional polymer of the present invention is The Nafion solution is spin-coated on the flat substrate 40 to produce a coating (S10) with a thin Nafion film layer 32. {A in FIG.

Here, the manufacture of the thin Nafion film layer 32 by using the spin-coating method, taking into consideration that the Nafion solution has a viscosity, to produce a Nafion thin film having an even thickness In order to spray SU-8 (44) series photoresist (PR) 52 on the wafer, sprinkle Nafion dispersion on the wafer, rotate it at a constant rpm, and dry it. By repeating to produce a Nafion film layer (film) (32) of the Nafion solution. {20wt% Nafion dispersion was used for spin-coating for 40 seconds at 1000rpm and the drying process was repeated. As a result, a thin film with a thickness of about 20㎛ was produced. The thin film is immersed in D.I.water and hydrated so that it can be easily removed from the wafer}

Then, the carbon nanotubes (CNT) 34 are sprayed (S20) on the Nafion film layer 32 by a spray method.

Next, spin coating Nafion solution on the carbon nanotubes 34 again to coat the Nafion film layer 32 so that the carbon nanotubes 34 are attached in a layered structure to form a composite (S30). {C} in FIG. 5

Full-functional dynamic polymer (IPMC) 124 is formed by the same process as the full-functional dynamic polymer 124 is a carbon nanotube (CNT) (34) and Nafion film layer 32 to produce a layered composite In order to obtain a Nafion film layer 32 having a predetermined thickness, a full-function dynamic polymer 124 is manufactured by spin-coating a silicon wafer (Si-wafer) onto the substrate 30.

Here, spraying the carbon nanotubes (CNT) 34 on the Nafion film layer 32 by the spray method is a carbon nanotube (CNT) 34 in the Nafion film layer (32) to form a send position structure To fabricate the composite, first make a thin film using spin-coating method, and then when the film layer is cured about halfway at 30 ° C by using a hot-plate to shorten the process time To dry, at the same time to put the carbon nanotubes (CNT) (34) in ethanol in order to spray the carbon nanotubes (CNT) (34) using carbon nanotubes (CNT) using ultra-sonic Evenly disperse the (34), and then use a compressor and an air-brush to keep a certain distance from the film layer at a constant pressure (in the experiment, spray at a pressure of 2 kg / cm2 at a distance of 15 cm). / ethanol dispersion and then the Nafion film layer (32) Thereby screen. By repeating the above process by spin-coating a Nafion-dispersion on the fully cured film layer, the laminated full functional copper polymer 124 is manufactured.

The full-function dynamic polymer (IPMC) 124 is a material for manufacturing the collection driver 120, with the disadvantage that the driving force is reduced due to the change in resistance due to the change in shape when a driving current is applied and deformation occurs. I have it. In order to solve this disadvantage, CF (Carbon fiber) and carbon nanotubes (CNT) 34, which are conductive materials, are formed in Nafion, which is a material of the full-function dynamic polymer (IPMC) 124. After producing a CNT / Nafion composite mixed in a layered structure having a using it was produced as a full-function dynamic polymer (IPMC) (124).

In addition, Figure 6 is a process diagram showing a method for producing a mesh including the full-featured polymer of the in-body waste removal collector for medical treatment using a net attached to the full-function copper polymer according to the present invention, Figure 7 is a process diagram of Figure 6 in accordance with the present invention This is an exemplary view of the state.

As shown in the drawings, the mesh manufacturing method including the full-featured polymer of the in-body waste removal collector for medical use using a mesh attached to the full-featured polymer of the waste removal collector of the present invention is deposited aluminum sacrificial layer 42 A photo mask 46 is spin-coated with the SU-8 44 on the substrate 40 capable of light transmission, and a predetermined pattern is recorded on the structure having a thickness. A structure having a specific pattern is formed through the process of exposure and development (S110). {a, b, c, d} of FIG.

At this time, the SU-8 (44) is a negative-photoresist (PR) (52) mainly used to make a structure having a high aspect ratio on a micro-scale. The PR-8 of the SU-8 (44) series is a polymer material whose chemical properties change when it is supplied with energy from the outside. It is a photo of MEMS process that is generally used to make a micro-scale structure using PR (52). The etching process (photo-litho process) is carried out. In response to UV-light, the part where the light is irradiated and the remaining part is removed is called positive PR and the opposite PR is called negative PR. SU-8 (44) Edo is subdivided according to the height (thickness) of the structure to be manufactured.

Here, the MEMS (Micro-Electro-Mechanical-System) may be referred to as a technology for designing and manufacturing various mechanical and electrical devices with a small size of micro-scale based on the manufacturing technology of semiconductor integrated circuits.

Next, a photo mask 46 having a predetermined pattern is recorded on the structure spin-coated with SU-8 44 at a predetermined thickness thicker than the thickness formed on the structure, and exposed. And forming a structure having a recess 48 through a development process (S120). {E, f, g} of FIG.

The full functional copper polymer (IPMC) 124 is inserted into the mold in which the recess 48 is formed (S130).

In addition, a photo mask 46 having a predetermined pattern is recorded on the structure spin-coated with SU-8 44 on the full-function dynamic polymer (IPMC) 124 protruding from the mold, and exposed. A structure having a specific pattern is formed through an expose and a development process (S140). {i, j, k of FIG. 6]

Finally, the aluminum sacrificial layer 42 is etched from the structure to produce a fully functional copper polymer (IPMC) 124 coated with SU-8 (44) (S150).

In addition, Figure 8 is a process chart showing a full-function dynamic polymer insertion manufacturing method of the process of Figure 6 according to the present invention, Figure 9 is a state diagram for the process of Figure 8 in accordance with the present invention.

As shown in the figure, the method of inserting a full-function dynamic polymer (IPMC) 124 into the mold forming the groove 48 of the substrate 40 that can transmit light is a biocompatible SU in the groove 48 The photoresist 52 is applied (S210) with a photosensitive material of -8. {G-1 in FIG. 9}

Then, the full-function dynamic polymer (IPMC) 124 is inserted into the groove 48 (S220).

The photo-resist process is performed on the bottom surface of the transparent substrate 40 having a pattern formed by low temperature hardening of the photoresist 52 of the recess 48 into which the full functional copper polymer (IPMC) 124 is inserted. The full-function dynamic polymer (IPMC) 124 is attached (S230).

In addition, the photoresist 52 is not covered with the substrate 40 in order to apply a current to the full functional copper polymer (IPMC) 124.

At this time, when irradiating light on the bottom surface of the substrate 방법 a method of irradiating the bottom surface of the mercury bulb irradiated with UV-light and the bottom surface of the substrate and when the mercury bulb is fixed on the upper side, using the viscosity of the PR 52, It is possible to use a method of flipping the substrate so that the bottom surface is irradiated.

In this case, when a simple function of fully functional functional polymer (IPMC) 124 is inserted between the SU-8 (44) structures in which the recess 48 is formed, the functional functional polymer (IPMC) during spin-coating that rotates at a high speed. Since 124 can escape between the SU-8 (44) structures, first, a photoresist (PR) having a certain amount of biocompatibility on the underside (the electrode patterned portion) of the SU-8 (44) structure to prevent this. (52) is applied thinly and then sandwiched the full functional copper polymer (IPMC) (124), the photoresist (PR) (52) is fixed by curing at low temperature, and then photoresist (PR) (52) through a transparent substrate having a pattern Since UV-light is irradiated on the coated surface, it is possible to fix the full functional dynamic polymer (IPMC) 124. This prevents the full-function dynamic polymer (IPMC) 124 from being spaced apart or separated from the SU-8 (44) structure in a process requiring high speed rotation later.

As described above, in the waste removal collector 200 of the present invention, the collection driver 120 made by using the full-featured polymer 124 around the cylindrical body 110 is symmetrically positioned, and the collection drive unit ( Through the method of differentially driving 120, the position of the waste removal collector 200 may be controlled and maintained in the cross-sectional direction in the blood vessel 10.

In addition, a structure in the form of a mesh 122 made of a polymer that is bio-friendly and has light photosensitivity is located between the collection drive unit 120 to prevent small wastes 20 from escaping between the collection drive unit 120. In addition, it is possible to prevent the phenomenon that the blood is sucked together in the process of removing the wastes in vitro using a tube by using the phenomenon that the wastes 20 are sandwiched between the structures of the mesh 122 form.

The collection drive unit 120 is manufactured based on the full-function dynamic polymer 124 to actively deform its shape so that the collection drive unit 120 is folded to the body until the waste removal collector 200 reaches the lesion. It is possible to move in the state when it starts collecting.

In addition, the waste removal collector 200 in the cross-sectional direction of the blood vessel 10 through a method of varying the displacement of the full-function dynamic polymer 124 of each collection drive unit 120 by adjusting the voltage applied to the collection drive unit 120. While controlling the position of the) while the collection drive unit 120 serves to maintain the position of the waste removal collector 200 while pushing the vessel (10) wall.

As such, it is difficult to remove the waste 20 directly at the time of surgery, such as chronic complete stenosis, by inserting the waste removal collector 200 of the present invention compared to the case of using the drug network 122 of the capture driver 120 By collecting the waste 20 with the suction pipe 140, it is possible to quickly and reliably remove a large amount of debris (waste).
