Will structure with magnet lock device {Artificial limb structure having magnet lock device}

The present invention relates to a will structure that facilitates the adsorption and desorption of the will and the socket liner using a magnet lock device having an electromagnet magnet.

The artificial limb is artificially made to suit a hand or foot defects in appearance or function. Some of the joints have the same shape and function as the joint. According to the purpose and site to be used, it is divided into several things, but generally it is divided into the upper limb will called a prosthetic and the lower limb called a prosthetic.

To use the will, first wear a socket liner on the cut, then connect the socket liner with the will. The existing device for connecting the will and the socket liner was a pin lock. As shown in Figure 2, the pin lock is a method of connecting to the will by fixing the metal pin (P) to the connection end of the socket liner. In the case of pin lock, since the area of the fixing part connecting the cutting part and the will is only the pin (P) cross-sectional area, it is difficult to grasp the weight in the standing posture and becomes a factor of noise generation due to the play of the fastening part during walking.

Figure 2 shows a fastening configuration of the existing pin lock device (left) and the willing magnetic lock device (right) according to the present invention. As shown in the figure, the pin lock is difficult to use when the short end is long because the length connecting the cutting part and the will is long. Magnetic lock has the advantage that it can be used even when the length of the end is made of a thin thickness.

The present invention, unlike the prior art, to develop a magnetic lock device using a permanent magnet and an electromagnet mixed with an electromagnet, and to develop a magnetic lock socket for interacting with the object, an object of the present invention It is to provide a will structure that facilitates the adsorption and detachment of the will and the socket liner of the socket portion using a magnet lock device having a magnet.

According to an aspect of the invention, the will comprising a magnetic lock device; And a socket portion detachably coupled to the will, and the socket portion includes: a socket liner worn on the cut portion; A socket body having a socket liner disposed therein; And a magnet adsorption member attached to the socket liner and capable of being adsorbed and detached by a magnetic lock device and a magnetic force, the magnetic lock device comprising: a permanent magnet generating a magnetic field; An iron core transferring the magnetic field generated from the permanent magnet toward the adsorption member; And an electric coil installed in the iron core, and magnetic flux generated by the permanent magnet flows through the iron core and the adsorption member, so that adsorption force is generated between the permanent magnet and the adsorption member. The magnetic field device is provided with a magnetic lock device in which a magnetic field opposite to the magnetic field is generated and magnetic flux generated in the permanent magnet circulates into the iron core, and the magnetic magnet device and the suction member are detached by losing the suction force between the permanent magnet and the suction member. A structure is provided.

At this time, the socket liner is made of a silicone material, the suction member may be formed with a hole for increasing the bonding force of the socket liner with the silicone material.

At this time, the surface of the socket liner may be attached to the one-way span fabric so that the socket liner is stretched only in the width direction and not stretchable in the longitudinal direction.

In this case, the socket liner may have a two-stage structure of an inner member made of a silicone material having a hardness of 5 to 20 and an outer member made of a silicone material having a hardness of 30 to 60.

The will structure includes a battery for supplying power to the magnetic lock device; A current regulator for regulating the current supplied from the battery to the magnetic lock device; And it may further include a power switch for supplying power to the magnet lock device.

At this time, the power source of the battery can be used only when the socket liner and the socket liner are detached.

The zero-electron magnetic lock implemented in the present invention uses a permanent magnet and an electric coil together, and absorbs the adsorption member attached to the socket liner by the force of the permanent magnet. There is no By changing the polarity of the permanent magnets by the current supplied to the electric coil, the adsorption member can be adsorbed or desorbed, and the power is supplied only in the short time of adsorption and desorption, thus saving energy and ensuring safety and reliability. That's the way it is. In addition, since the power is turned on only when the current is on / off, there is no increase in temperature, which prevents heat from wearing part, thereby relieving stuffiness at the end.

In addition, magnet locks using magnetron magnets have a wide area connecting the cutting end and the will, which makes walking very stable and eliminates pain. When the elasticity of the end of the silicone socket liner is increased, friction may occur repeatedly between the skin of the end portion and the silicone socket liner, and abrasion may occur at the end end. There is no repetitive expansion and contraction action of the socket liner, thereby preventing abrasion.

The magnet lock case 1 is mounted on the distal end of the will 10 and serves to receive and protect the magnet lock device 2 therein. The magnet lock case 1 is made of metal, plastic, or the like.

The magnet lock device 2 is a magnet system composed of a mixture of permanent magnets and electromagnets, and is a device that magnetically connects the socket liner 9 and the will 10 of the socket portion 20 to be worn on the cut portion.

The magnetic lock device 2 includes a permanent magnet 14 for generating a magnetic field, an iron core 12 for transferring a magnetic field generated from the permanent magnet 14 toward the adsorption member 8, and a permanent magnet 14 for the permanent magnet 14. It consists of an electric coil 13 to facilitate the adsorption and desorption electrically in response to the generated magnetic field.

The battery 3 serves to supply power to the magnetic lock device 2, and when the rechargeable secondary battery such as a lithium ion battery is used, the battery 3 may be charged and reused when discharged. The battery 3 can be used only at the time of detachment of the socket liner 9 of the socket portion 20, thereby preventing power consumption. Although the battery 3 is installed in the lower part of the magnet lock apparatus 2 in the figure, the position is not limited to this and can be changed into another position.

The current regulator 4 serves to flow a constant current to the coil so that the battery 3 is fully charged to operate smoothly to the lowest output at which the detachment operation occurs. In the figure, the current regulator 4 is installed in the lower portion of the magnet lock device 2, but the position thereof is not limited to this and can be changed to another position.

The power switch 5 is a magnetic lock switch, serves to supply and cut off current from the battery 3 to the coil of the magnetic lock device 2, and typically uses an ON / OFF button method. In the figure, the power switch 5 is installed on the side of the magnet lock device 2, but the position is not limited to this and can be changed to another position.

The current regulator 4 and the power switch 5 are control devices for easily detachable attachment and detachment of the socket liner 9 and the will 10 of the socket portion 20, the socket liner 9 of the socket portion 20 When detaching, power is supplied to the magnetic lock device 2 by the power switch 5 to block the magnetic force of the permanent magnet, and the current regulator 4 controls the current of the battery 3.

The will-connected pyramid 6 is installed under the magnet lock device 2, and is a device for connecting the magnet lock device 2 to the body of the will 10, and is made of aluminum, titanium, stainless steel, or the like.

The will connection adapter 7 is installed at the bottom of the will connection pyramid 6 and is a device for connecting the magnet lock device 2 to the body of the will 10.

The adsorption member 8 is a portion containing a metal attached to the lower end of the socket liner 9 of the socket portion 20 so as to be adsorbed by the magnet lock device 2.

The socket liner 9 is a liner installed inside the socket portion 20. In order to apply the will 10 to the cut portion, a plastic concave socket body 11 is used. The socket liner 9 serves to protect and cushion the skin between the socket body 11 and the cut portion. .

The socket liner 9 is formed of a low hardness silicone material (Shore A 5 to 20) inside the upper portion where the cut portion is inserted to give a soft and comfortable fit, and a high hardness silicone material (Shore A 30) on the lower outside. To 60) to have a two-stage structure to limit the stretching action by the weight of the will 10 during walking.

In addition, a one-way span fabric may be attached to the surface of the socket liner 9. When walking for a long time while wearing the will (10), the silicone socket liner is stretched during the walking swing by the weight of the will (10) and repeats the stretching and contracting movement when landing the foot, so that the silicone socket liner and It is a requirement that abrasions occur due to repeated friction between the skin of the end portions. Abrasion is a wound in which the skin is damaged by an external force almost parallel to the skin, which is a trauma in which the skin is scraped or rubbed off. Mainly, the epidermis is peeled off, leaking lymph and bleeding from the dermis, causing them to coagulate and crust. In order to prevent abrasion due to the friction of the end portion, the unidirectional span fabric is attached to the surface of the socket liner 9, wherein the unidirectional span fabric is stretched only in the width direction of the socket liner 9 and in the longitudinal direction. It does not have elasticity.

3 is a schematic view showing the operation principle of the electromagnet type, the electromagnet type as shown in Figure 3, the electric coil 13 for generating a magnetic field, and the magnetic field generated in the electric coil 13 toward the adsorption member (8) It consists of an iron core 12 for the purpose.

As shown in the left figure of FIG. 3, when the current I flows through the electric coil 13, the magnetic flux Φ is generated in the electric coil 13, and the magnetic flux is the iron core 12 and the suction member 8. Flow through the suction force is generated between the electromagnet and the adsorption member (8). As shown in the right figure of FIG. 3, when the electric current is interrupted in the electric coil 13, no magnetic field is generated in the electric coil 13, and thus the adsorption force between the electromagnet and the adsorption member 8 is lost.

Therefore, the electromagnets can be manufactured in any form, whether rectangular or circular, but if the electromagnet is composed only of the electromagnets, the electromagnets are not suitable. The reason is that the electrical energy is required while the adsorption force is generated, and a large capacity battery must be installed, and the volume and the weight of the electromagnet are increased as many electric coils are needed to suppress the heat generated from the electromagnet. Because it has.

Figure 4 is a schematic diagram showing the operation principle of the permanent magnet type, permanent magnet type as shown in Figure 4, the permanent magnet 14 for generating a magnetic field, and the magnetic field generated in the permanent magnet 14, the adsorption member (8) Consisting of an iron core 12 for delivery to the side. When the permanent magnet 14 is installed inside the iron core 12, magnetic flux Φ is generated by the permanent magnet 14, and the magnetic flux flows through the iron core 12 and the adsorption member 8, thereby permanent magnet 14. ) And the suction member 8 is generated.

Since the permanent magnet type does not have a special method for blocking the magnetic force generated in the permanent magnet 14, the adsorption member 8 is forcibly detached using a physical force, or another permanent magnet is mounted to the adsorption member 8. To return the magnetic flux (Φ) generated to the inner core 12 should be adopted.

In the method to achieve in the present invention, the circular permanent magnet type is easy, but the handicapped person with a disability has difficulty in detaching, and when another permanent magnet is inserted to more easily implement the detachment, the volume and the weight increase. It has a disadvantage.

Figure 5 is a schematic diagram showing the operation principle of the electromagnet type, Figure 6 is a cross-sectional view showing the operation principle of the magnet lock (left: when the power supply, right: when the power supply) according to the present invention.

As shown in FIGS. 5 and 6, the zero-electron type includes a permanent magnet 14 for generating a magnetic field, an iron core 12 for transferring a magnetic field generated from the permanent magnet 14 toward the adsorption member 8, and a permanent magnet ( It is composed of an electric coil 13 to facilitate the adsorption and desorption electrically in response to the magnetic field generated in 14).

5 and 6, when the permanent magnet 14 is mounted inside the iron core 12, the magnetic flux Φ is generated by the permanent magnet 14, and the magnetic flux is adsorbed with the iron core 12. It flows through the member 8 so that a suction force is generated between the permanent magnet 14 and the suction member (8).

5 and 6, in order to block the magnetic force generated in the permanent magnet 8, the current I to the electric coil 13 to generate a magnetic field opposite to the magnetic field direction of the permanent magnet 14 When flowing through, the magnetic flux (Φ) generated in the permanent magnet 14 is circulated into the iron core 12, so that the adsorption force with the adsorption member (8) is lost can be easily removable.

The principle of the zero-electron type is to change the direction of the generated magnetic field rather than to remove the magnetic field generated in the permanent magnet, especially the circular zero-electron type that can maintain the constant performance without the use time and the permanent magnet potato is most suitable .

The necessity of the electromagnet type lock device is as follows. Because the connection between the existing will and the socket is pin type, local pressure may be generated at the bottom of the end portion around the pin. If the cuts are not round and the bones are protruding, the severity is increased, which may result in scarring, inflammation, necrosis and pain of the tissue at repeated weight loads. It can form walking and cause secondary diseases associated with walking. Therefore, a new connection structure is needed to distribute the pressure evenly across the bottom of the end and to reduce the local pressure, and to give the weight of the body evenly across the bottom of the end.

The effects of the lock device on the electromagnet type are as follows. It is possible to prevent local pressure concentration at the lower end of the end formed when the fin method. It can prevent scars, inflammation, necrosis, and pain in the tissues of the local area due to local pressure reduction. The pressure is evenly distributed throughout the lower end of the end, so that the ideal force distribution is achieved at the end of the walk and a balanced walking is possible. Fatigue is reduced when walking for a long time compared to the conventional pin connection method and forms an ideal walk close to normal walking.

7 is a fastening configuration of a magnetic lock device and a socket liner detachable to a magnetic force according to the present invention. As shown in FIG. 7, the lower end of the socket liner 9 responds to the magnetic force of the magnetic lock device 2. The metal adsorption member 8 is attached so that attachment and detachment are possible. The suction member 8 may be manufactured in a circular spherical shape to increase the adhesion force with the magnet lock device 2. The adsorption member 8 may be formed by attaching a hole formed on the circumference of the socket liner 9 so as to be well bonded with the silicon material. As for the material of the adsorption member 8, it is preferable to use an iron type material with few alloys so that it may adhere to a magnet well.
