Description

Technical Field

[0001] This invention relates to the field of prosthetics technology, specifically to a prosthetic wearing system, and more particularly to a prosthetic wearing system that includes an insert made of PE or PP material and / or an insulating structure including a prosthetic receiving cavity made of PE material, and is capable of transmitting electrical signals. Background Technology

[0002] A prosthesis is a medical device designed to restore the form or function of an amputee's limb. Current prosthetic systems typically consist of a flexible sleeve that directly contacts the residual limb and an external mechanical prosthetic device (including knee and ankle joints) with a prosthetic socket. The prosthetic socket can be designed differently depending on the specific needs. For example, carbon fiber prosthetic sockets are commonly used for lightweight and rigidity purposes. Thermoplastic prosthetic sockets, such as those made of PE (polyethylene) or PP (polypropylene), are commonly used to allow adjustment based on the force applied by the patient. These sockets can be heated to soften the material and then adjusted to the desired shape. After adjustment, they are cooled to regain their rigidity for daily use. Alternatively, for ease of wear, the flexible sleeve can be detachably and conveniently connected to a lock on the prosthetic socket via a prosthetic locking post.

[0003] With the development of technology, modern prostheses have evolved from simple mechanical support structures to intelligent and mechatronic designs. Flexible bushings can integrate functional modules such as bioelectric sensors, temperature sensors, and heating units, which can be electrically connected to the control unit and power supply unit on the prosthesis itself.

[0004] However, during product testing, it was found that if the electrical connection is achieved using a conventional independent external electrical interface or connector, this separate electrical connection method will cause the wearable structure and the prosthesis body to require additional plugging and unplugging of the electrical connector during disassembly and assembly, which is cumbersome and increases the burden of use.

[0005] Existing connection structures only provide mechanical fixation and cannot achieve synchronous transmission of electrical signals. When wearing a prosthesis, users not only need to complete the mechanical locking but also need to find and connect tiny electrical interfaces, which is extremely difficult for people with mobility impairments. Summary of the Invention

[0006] To overcome the shortcomings mentioned above, the present invention aims to provide a prosthetic wearing system that can synchronize mechanical wearing actions with electrical connection actions.

The first flexible contact type rotatable connector also provides axial redundancy to maintain a conductive connection within a certain axial range.

[0011] As a further aspect of the present invention: the insert is made of PE or PP material to have different rigidity levels between rigid threaded parts and flexible bushings.

[0012] As a further aspect of the present invention: the lock part includes a lock body and a lock cylinder that can be releasably engaged with a prosthesis lock cylinder, the lock cylinder being a conductive lock cylinder and the prosthesis lock cylinder being a conductive prosthesis lock cylinder; One of the connection lines of the first connection circuit is connected to the prosthetic locking post, and a conductive connection is formed between the prosthetic locking post and the lock cylinder. One of the connection lines of the second connection circuit is connected to the lock cylinder.

[0013] As a further aspect of the present invention: the prosthesis locking post is configured in a tubular shape to form a wiring channel, the wiring channel opening at the distal end of the prosthesis locking post and coinciding with the axis of the prosthesis locking post; The first connection circuit includes a second connector disposed at the far end opening of the wiring channel, and the second connection circuit correspondingly has a second mating connector disposed on the lock body; The second connector makes a conductive proximity connection with the second mating connector based on the engagement of the lock cylinder with the prosthesis lock post after it is inserted into place; One of the second connectors and the second mating connector is a second flexible contact type rotatable contact connector, and the other is a second ring type connector; When the prosthesis locking post is rotatably connected to the locking part, the second resilient contact type rotatable contact connector maintains a conductive connection within at least a portion of the rotation range of the prosthesis locking post relative to the locking part; The second flexible contact type rotatable connector also provides axial redundancy to maintain a conductive connection within a certain axial range.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-9 This disclosure relates to a wearable structure 2 that is detachably connected to a patient's residual limb and detachably connected to a prosthetic device 3; after connection, the wearable structure 2 and the prosthetic device 3 can be electrically connected so that the electrical module of the wearable structure 2 and the electrical module of the prosthetic device 3 can transmit electrical signals; and can be detached from the prosthetic device 3 freely (including the aforementioned detachable connection and electrical connection).

[0024] Please see Figure 1-9 This disclosure also relates to a prosthetic device 3 that is detachably connected to the aforementioned wearable structure 2; after connection, the wearable structure 2 and the prosthetic device 3 can be electrically connected so that the electrical module of the wearable structure 2 and the electrical module of the prosthetic device 3 can transmit electrical signals; and can be detached freely from the wearable structure 2 (including the aforementioned detachable connection and electrical connection).

[0025] Specifically, this disclosure relates to a prosthetic wearing system 1, which includes the aforementioned wearing structure 2 and prosthetic device 3.

[0026] More specifically, this disclosure includes a wearable structure 2 that is detachably connected by its own locking structure and simultaneously electrically connected based on the locking state of the locking structure, and a prosthetic device 3 (including a corresponding locking part) that works with it.

[0027] More specifically, this disclosure includes a prosthetic wearable system 1 that utilizes integrated mechanical and electrical coupling to improve the electrical signal connection and transmission challenges of the wearable structure 2.

[0028] Please see Figure 1-9 In this embodiment, the wearable structure 2 includes: a flexible sleeve 21 shaped to accommodate at least a portion of the patient's residual limb, the proximal end of the flexible sleeve 21 having a wearing opening 22 suitable for the patient's residual limb to enter, and the distal end of the flexible sleeve 21 having a prosthesis locking post 23.

[0029] The prosthetic device 3 includes: a prosthetic receiving cavity 31, the proximal end of which has a receiving port 32 for receiving the residual limb and a flexible bushing, and the prosthetic receiving cavity 31 has a locking portion 33 that engages with the prosthetic locking post.

[0030] The locking portion 33 includes a central opening 334 sized to accommodate a prosthesis locking post, which releasably engages the prosthesis locking post 23 on the distal end of the flexible bushing when the stump and flexible bushing are inserted into the prosthesis receiving cavity 31.

[0031] The prosthetic wearing system 1 also includes: a first electrical module 4 disposed on the flexible bushing 21; a first connection circuit 5 disposed on the prosthetic locking post 23; a second connection circuit 6 disposed on the locking part 33; and a second electrical module 7 disposed on the prosthetic receiving cavity or locking part (including other structural parts, prosthetic structures, and prosthetic parts assembled to the prosthetic receiving cavity or locking part, such as the knee joint assembly 8 and the upright assembly).

[0032] The first electrical module 4 is electrically connected to the first connecting circuit 5, and the second electrical module 7 is electrically connected to the second connecting circuit 6.

[0033] The first connection circuit 5 and the second connection circuit 6 achieve contact electrical connection / disconnection electrical connection based on the engagement / release status of the prosthetic locking pin 23 and the locking part 33, thereby forming an electrical connection / disconnection between the first electrical module 4 and the second electrical module 7.

[0034] Specifically, the engagement state corresponds to the contact electrical connection, and the release state corresponds to the disconnection electrical connection.

[0035] In some embodiments, a method of using a prosthesis may include: fitting a flexible sleeve 21 onto the residual limb; inserting the residual limb and the flexible sleeve into the prosthesis receiving cavity 31, while simultaneously allowing the prosthesis locking pin 23 on the distal end of the flexible sleeve to enter the central opening 334 of the locking portion installed at the distal end of the prosthesis receiving cavity; locking the prosthesis locking pin 23 through the locking portion 33 to complete the electrical connection between the first electrical module 4 and the second electrical module 7.

[0036] In some embodiments, allowing the prosthetic locking pin 23 to enter the central opening 334 of the locking portion includes releasably engaging the prosthetic locking pin 23 onto the locking portion 33.

[0037] In some embodiments, the flexible bushing 21, which is quite elastic, can be made to fit the size and / or shape of the patient's residual limb, and correspondingly form a proximal end and a distal end.

[0038] Typically, the flexible sleeve 21 is made of an elastic material so that it can be rolled up and fit snugly onto the stump.

[0039] In some embodiments, the flexible liner 21 is, for example, a silicone liner or a liner with certain elastic wrapping properties, so that after the flexible liner 21 is worn on the patient's residual limb through the wearing port 22, the elastic wrapping can be used to better hold the flexible liner 21 on the patient's residual limb.

[0040] In some embodiments, the prosthesis locking post 23 may be mounted to the distal end of the flexible bushing 21 via a threaded end 231 on the prosthesis locking post, the threaded end 231 being compatible with a threaded structure on the distal end of the flexible bushing 21.

[0041] In some embodiments, the distal end of the flexible bushing 21 has an insert 211, on which a threaded structure may be provided, and the insert 211 may be integrated with the flexible bushing 21.

[0042] In some embodiments, the insert 211 is provided with a rigid threaded member 212, and the threaded structure is provided on the rigid threaded member 212. The rigid threaded member 212 can achieve a tighter connection between the threaded structure and the threaded end 231 of the prosthetic locking post.

[0043] Insert 211 serves as a transition structure connecting flexible bushing 21 and rigid threaded member 212. It has different rigidity levels (e.g., plastic and / or hard rubber inserts with basic rigidity) between rigid threaded member 212 and flexible bushing 21, so that rigid threaded member 212 can be well transitioned and held on flexible bushing 21.

[0044] For example, insert 211 is made of materials such as PE (polyethylene) and PP (polypropylene). While having different rigidity levels between the rigid threaded part 212 and the flexible bushing 21, it also has insulating properties so as to prevent leakage when the rigid threaded part has the following conductive function.

[0045] In some embodiments, the rigid threaded member 212 may be a conductive rigid threaded member (e.g., stainless steel, copper) based on the following conductivity requirements.

[0046] In some embodiments, the thread on the threaded end 231 may be an external thread, and correspondingly, the rigid threaded member 212 has a threaded hole corresponding to the threaded end.

[0047] The rigid threaded part 212 has a mating end face 213 in the threaded hole that corresponds to the end face of the threaded end. In other words, the rigid threaded part 212 has a mating end face 213 that corresponds to the end face of the threaded end, or the rigid threaded part 212 has a mating end face 213 that corresponds to the end face of the threaded end along the axial direction of the prosthetic locking post.

[0048] In some embodiments, the thread on the threaded end can be an internal thread, that is, the end face of the threaded end has a threaded hole, and the rigid threaded part has an external thread corresponding to the threaded hole.

[0049] The distal end face of the rigid threaded component forms a mating end face, and the threaded hole at the threaded end has an end face corresponding to the mating end face. In other words, the end face inside the threaded hole at the threaded end corresponds to the mating end face of the rigid threaded component along the axial direction of the prosthetic locking post.

[0050] In some embodiments, the prosthetic locking post 23 can be removed and installed according to different needs through the above-described screw connection design, such as replacing different prosthetic locking posts or removing it for maintenance.

[0051] The scope of this disclosure also includes other methods for connecting the prosthesis locking pin to the flexible bushing, including but not limited to detachable and fixed connections. For example, the flexible bushing has a snap-fit ​​structure, and the prosthesis locking pin has a mating locking block, which is secured and held in place by the snap-fit ​​structure.

[0052] In some embodiments, the prosthetic locking post 23 further includes a locking tooth row 232, which can be releasably accommodated in the locking portion 33.

[0053] In some embodiments, the threaded end 231 is disposed on the proximal end of the prosthetic locking post 23, and the locking tooth row 232 is disposed on the distal end of the prosthetic locking post 23.

[0054] In some embodiments, the teeth of the locking tooth row 232 may be arranged along the axial direction of the prosthetic locking post 23, that is, spaced apart from the proximal end of the prosthetic locking post 23 to the distal end of the prosthetic locking post 23.

[0055] In some embodiments, the teeth of the locking tooth row 232 extend circumferentially along the prosthesis locking post to form annular teeth 233. The annular teeth 233 can maintain engagement with the gear 3324 described below in the circumferential direction, that is, the patient can adjust the circumferential rotation angle of the prosthesis locking post 23 (specifically the locking tooth row) according to actual use.

[0056] In some embodiments, the lock portion 33 may include a lock body 331 and a lock cylinder 332 with a release button.

[0057] In some embodiments, the outer sleeve 3323 of the lock cylinder 332 has external threads, and the lock body 331 has a corresponding screw hole 333. The outer sleeve 3323 of the lock cylinder is tightened onto the screw hole 333 of the lock body through the external threads, and the portion of the lock cylinder 332 with gears 3324 passes through the screw hole 333 into the internal space of the lock body (communicating with the internal space of the lock body into which the prosthetic locking rod is inserted from the central opening).

[0058] The gear 3324 on the lock cylinder 332 is limited to unidirectional rotation. When the prosthetic locking pin 23 is inserted, the teeth of the locking gear row 232 actuate the gear 3324 (rotating in the rotatable direction), allowing the locking gear row 232 to slide into place. However, the unidirectional rotation of the gear 3324 restricts the locking gear row 232 from disengaging. Pressing the release button 3322 pushes the gear 3324 out of its original position (the position that engages with the locking gear row), thus releasing the restriction on the disengagement of the locking gear row 232.

[0059] Specifically, the lock cylinder 332 includes a return spring 3321, a release button 3322, an outer sleeve 3323, a gear 3324 (usually a spur gear), a one-way bearing 3325, and a connecting shaft 3326.

[0060] The connecting shaft 3326 is slidably disposed within the outer sleeve 3323 along its axial direction. One end of the connecting shaft 3326 extends out from one end of the outer sleeve 3323 and is coaxially connected to the gear 3324 via a one-way bearing 3325, allowing the gear 3324 to rotate unidirectionally on the connecting shaft 3326. The other end of the connecting shaft 3326 is connected to the release button 3322, and is configured such that the release button 3322 at least partially extends out from the other end of the outer sleeve 3323.

[0061] The release button 3322 is connected to a limit slider 3327 inside the outer sleeve. The outer sleeve 3323 has a guide rail 3329 that slides with the limit slider. The guide rail 3329 allows the limit slider 3327 to slide axially along the connecting shaft 3326 and restricts the limit slider 3327 from rotating circumferentially along the connecting shaft 3326. The release button 3322 is provided with a screwdriver hole outside the outer sleeve.

[0062] The other end of the outer cover 3323 is connected to an anti-slip component 3328 that cooperates with the limit slider to restrict the release button 3322 to slide on the outer cover 3323.

[0063] A pressing part 33210 is connected to the part of the connecting shaft 3326 located inside the outer sleeve. The return spring 3321 is located inside the outer sleeve and sleeved on the connecting shaft 3326. The return spring 3321 is adapted to be elastically deformed by the combined action of the pressing part 33210 and the constriction structure at one end of the outer sleeve 3323.

[0064] When the release button 3322 is pressed (force is applied from the other end of the connecting shaft to one end of the connecting shaft), the return spring 3321 is subjected to elastic deformation or aggravated elastic deformation by the combined action of the pressing part 33210 and the constriction structure at one end of the outer sleeve 3323.

[0065] When the locking tooth row 232 is inserted, the axial direction of the locking tooth row 232 is perpendicular or substantially perpendicular to the axial direction of the gear 3324 (or the axial direction of the reference connecting shaft), and the teeth of the locking tooth row 232 and the teeth of the gear 3324 are in meshing contact; and as the locking tooth row 232 is continuously inserted, the locking tooth row 232 continuously pushes the gear 3324 to rotate in the direction of allowable rotation through the aforementioned meshing.

[0066] After being inserted into place, the unidirectional rotation of gear 3324 restricts the disengagement of locking gear 232.

[0067] When the release button 3322 is pressed, the gear 3324 is pushed and disengages from the locking gear 232 along the axial direction of the gear 3324; after the gear 3324 is completely disengaged from the locking gear 232, that is, the locking gear 232 is released from the unidirectional rotation restriction of the gear 3324, the locking gear 232 can be disengaged from the lock body 331 (specifically the center opening) in the opposite direction from the original insertion direction.

[0068] In some embodiments, one of the connection lines of the first connection circuit 5 includes a prosthetic locking post, or one of the connection lines of the first connection circuit 5 is connected to the prosthetic locking post 23, and the prosthetic locking post 23 forms a conductive connection with the lock cylinder 332 and / or forms a conductive connection with the rigid threaded member 212.

[0069] In some embodiments, one of the connection lines of the first electrical module 4 includes a rigid threaded member 212, or in other words, one of the connection lines of the first electrical module 4 is connected to the rigid threaded member 212. The installation action of the prosthetic locking post 23 being installed onto the flexible bushing 21 (specifically the rigid threaded member) simultaneously achieves the conductive connection between the corresponding connection line of the first electrical module 4 and the corresponding connection line of the first connection circuit 5.

[0070] In some embodiments, one of the connection lines of the second connection circuit 6 includes a lock cylinder 332 that contacts the prosthesis lock post, or in other words, one of the connection lines of the second connection circuit 6 is connected to the lock cylinder 332, and a conductive connection is formed between the lock cylinder 332 and the prosthesis lock post 23.

[0071] That is, the lock cylinder 332 (at least the gear) is conductive, and the prosthetic locking pin 23 is also conductive. The contact between the lock cylinder 332 and the prosthetic locking pin 23 forms a connection between one of the connection lines of the second connection circuit 6 and the corresponding connection line of the first connection circuit 5.

[0072] In some embodiments, such as the second connection circuit, the connection line is a ground connection line or is used for ground connection function.

[0073] In some embodiments, such as the connection line of the second connection circuit, the connection line is a hot-swap detection line or used for hot-swap detection function. That is, when separating the wearable structure from the prosthetic device, the lock cylinder first unlocks the prosthetic locking pin to cancel the contact between the gear and the prosthetic locking pin, i.e., the hot-swap detection line is disconnected first; after the contact between the gear and the prosthetic locking pin is broken, the control unit on the first or second electrical module detects the live disconnection operation through the hot-swap detection line and performs corresponding protection control. For example, it performs control operations such as data backup and cache writing.

[0074] In some embodiments, a gasket 335 (conductive, such as stainless steel, copper, etc.) is configured, and the corresponding connection lines on the second electrical module 7 are connected to the gasket 335.

[0075] When screwing the outer sleeve 3323 of the lock cylinder, the washer 335 is the tightening washer between the outer sleeve 3323 and the lock body 331. That is, the installation of the lock cylinder 332 simultaneously realizes the electrical connection between the corresponding connection lines and the lock cylinder 332.

[0076] Specifically, the outer side of the outer sleeve 3323 has a pressing boss 33211. When the outer sleeve 3323 is connected to the lock body 331 by screwing, the pressing boss 33211 is formed to press the gasket 335 onto the lock body 331.

[0077] Thus, the contact lines in the lock cylinder 332 from the gear 3324 to the one-way bearing 3325, the connecting shaft 3326, and the outer sleeve 3323 (or may also include the return spring) are conductive. For example, the corresponding components can be made of stainless steel, copper, forged steel, etc., to achieve conductivity and a certain structural strength.

[0078] In some embodiments, the gasket 335 may be in the form of a semi-circular gasket, a ring-shaped gasket, a butterfly-shaped gasket, a corrugated gasket, etc.

[0079] In some embodiments, one side of the gasket has a connection pin extending radially along the outer casing, and the corresponding connection line of the second electrical module can be connected to the connection pin of the gasket, for example, by soldering.

[0080] The extended connecting pins can form a clearance, preventing the corresponding connecting lines from obstructing the outer casing when it is tightened onto the lock body. This clearance also allows for the use of heat-shrink tubing (not shown). Typically, the heat-shrink tubing is fitted and held in a heat-shrinkable manner at: the portion of the corresponding connecting line near the connecting pin, the portion of the corresponding connecting line in contact with the connecting pin, and the portion of the connecting pin near the corresponding connecting line.

[0081] In some embodiments, a wiring channel 234 suitable for wiring is formed on the prosthetic locking post 23, and at least a portion of the connection lines of the first connection circuit 5 are routed from the wiring channel 234 to achieve that the electrical connection lines are hidden or substantially hidden in the prosthetic locking post 23 and protected by the prosthetic locking post 23.

[0082] In some embodiments, the prosthetic locking post 23 is configured in a tubular shape, and the wiring channel 234 is a conduit for the prosthetic locking post 23.

[0083] In some embodiments, the wiring channel 234 is the central channel of the prosthetic locking post 23.

[0084] In some embodiments, the wiring channel 234 is at least aligned with the axis of the prosthetic locking post 23 at its proximal opening and / or distal opening.

[0085] In some embodiments, the wiring channel 234 has both the proximal opening 235 and the distal opening 236 of the prosthetic locking post 23 coinciding with the axis of the prosthetic locking post 23.

[0086] In some embodiments, the proximal opening 235 is formed on the end face of the threaded end 231.

[0087] In some embodiments, the first connection circuit 5 further includes a first connector 51 disposed in the proximal opening 235 of the wiring channel, and the first electrical module 4 has a first connecting fitter 41 disposed on the mating end face 213 of the rigid threaded member.

[0088] The first connector 51 achieves a conductive connection with the first connector mating device 41 based on the connection between the rigid threaded part 212 and the prosthetic locking post 23.

[0089] In some embodiments, one of the first connector and the first mating connector is a resilient contact rotatable connector and the other is a ring connector, and are respectively named the first resilient contact rotatable connector and the first ring connector.

[0090] For example, the first connector is a first resilient contact type rotatable contact connector, and the first mating connector is a first ring type connector; or, for another example, the first connector is a first ring type connector, and the first mating connector is a first resilient contact type rotatable contact connector.

[0091] In some embodiments, when the rigid threaded part is a rigid threaded part with a threaded hole, the first connecting mating part can be a first elastic contact type rotatable contact connector.

[0092] In some embodiments, when the threaded end is a threaded end with a threaded hole, the first connector may be a first resilient contact type rotatable contact connector and is configured to be located within the threaded hole.

[0093] The elastic contacts hidden inside the screw hole are well protected by the screw hole structure and are not easily damaged, bent or deformed.

[0094] In some embodiments, the prosthesis locking post is rotatably or rotatably connected to the flexible bushing, and a first resilient contact rotatable connector maintains a conductive connection within at least a portion of the rotation range of the prosthesis locking post relative to the flexible bushing.

[0095] In some embodiments, the first resilient contact rotatable connector also provides axial redundancy to maintain a conductive connection within a portion of the axial range.

[0096] In some embodiments, a rigid threaded component is taken as an example, which has a threaded hole: The first circular connector (first connector 51) includes a first insulating seat 511 mounted on a proximal opening 235, and at least one first circular contact 512 is mounted on the first insulating seat 511.

[0097] When there is only one first circular contact, the first circular contact is one of the center contact and the annular contact of different diameters, and the contact surface of the first circular contact faces the mating end face.

[0098] When there are multiple circular contacts, these contacts can be any combination of different types of center contacts and annular contacts of different diameters. For example, two circular contacts can consist of a center contact and one annular contact; two circular contacts can consist of two annular contacts of different diameters; three circular contacts can consist of one center contact and two annular contacts of different diameters; three circular contacts can consist of three annular contacts of different diameters, and so on.

[0099] The center contact and the annular contacts of different diameters satisfy the following condition: the center or center point is located on the axis of the prosthetic locking pin 23.

[0100] The annular contacts form an enclosure around the center contact, and the larger diameter annular contacts form an enclosure around the smaller diameter annular contacts.

[0101] The first flexible contact type rotatable contact connector (first connector 41) includes a second insulating seat 411 mounted on the mating end face 213. The second insulating seat 411 is provided with a first spring pin 412 (POGOPIN) corresponding to the first round contact. The first spring pin 412 has the same length direction as the axial direction of the prosthetic locking post 23, and the movable contact of the first spring pin 412 faces the prosthetic locking post 23.

[0102] For example, when there is a center contact and a ring contact, there is a first spring pin that elastically contacts the center contact (through the movable contact of the first spring pin and the internal spring) and a first spring pin that elastically contacts the ring contact.

[0103] When the threaded end 231 is rotatably connected to the rigid threaded part 212 by screwing, the first ring connector and the first elastic contact rotatable contact connector are adapted to maintain a conductive connection during the rotation process (tightening or loosening) caused by screwing, and are also adapted to maintain a conductive connection within a set axial range during axial distance changes (moving towards the proximal end or moving towards the distal end) caused by screwing.

[0104] At the same time, the provided elastic feedback can react on the screw connection between the threaded end 231 and the rigid threaded part 212, making the two less prone to loosening.

[0105] In some embodiments, the power lines and / or signal lines on the first electrical module 4 may be connected to the first spring pin or to different first spring pins.

[0106] In some embodiments, the plurality of first circular contacts 512 are designed to be insulated from each other, that is, the plurality of first circular contacts have no conductive contact with each other. For example, after the first circular contacts are positioned, they are held in place by the injection-molded first insulating seat 511, so that the plurality of first circular contacts will not be displaced and thus make contact.

[0107] In some embodiments, the plurality of first spring ejector pins 412 are designed to be insulated from each other, that is, the plurality of first spring ejector pins have no conductive contact with each other. For example, after the first spring ejector pins are set in position, their positions are held in place by the injection-molded second insulating seat 411, so that the plurality of first spring ejector pins will not be displaced and thus will not make contact.

[0108] In some embodiments, a wiring hole 214 is provided through the mating end face 213 of the rigid threaded member to facilitate the concealed wiring connection of the first electrical module 4 to the first spring pin 412.

[0109] In some embodiments, the first connection circuit 5 further includes a second connector 52 disposed at the far end opening 236 of the wiring channel, and the second connection circuit 6 correspondingly has a second mating connector 61 disposed on the lock portion 33 (specifically the lock body).

[0110] The second connector 52 achieves a conductive connection with the second mating connector 61 based on the insertion of the prosthetic locking post 23.

[0111] In some embodiments, one of the second connector 52 and the second mating connector 61 is a resilient contact rotatable contact connector and the other is a ring connector, and are respectively named the second resilient contact rotatable contact connector and the second ring connector.

[0112] For example, the first connector is a second flexible contact type rotatable contact connector, and the second mating connector is a second circular ring type connector; or, for another example, the second connector is a first circular ring connector, and the second mating connector is a second flexible contact type rotatable contact connector.

[0113] In some embodiments, the second mating connector may be a second resilient contact type rotatable contact connector and is configured to be located within the locking portion (specifically the lock body).

[0114] The elastic contacts hidden inside the lock body are well protected by the lock body and are not easily damaged, bent or deformed.

[0115] In some embodiments, the prosthesis locking post 23 is rotatably connected to the locking portion 33, and the second resilient contact rotatable connector maintains a conductive connection within at least a portion of the rotation range of the prosthesis locking post relative to the locking portion.

[0116] In some embodiments, the second resilient contact rotatable connector also provides axial redundancy to maintain a conductive connection within a portion of the axial range.

[0117] In some embodiments, taking a second mating connector as an example, where the second mating connector is a second resilient contact type rotatable contact connector: The second circular connector (second connector 52) includes a third insulating seat 521 mounted on the distal opening 236 of the prosthesis locking post, and at least one second circular contact 522 is mounted on the third insulating seat 521.

[0118] When there is only one second circular contact, the second circular contact is one of the center contact and the annular contact of different diameters, and the contact surface of the second circular contact faces the inside of the lock body along the axial direction of the prosthetic locking pin.

[0119] When there are multiple second circular contacts, these multiple second circular contacts are any combination of different types of center contacts and annular contacts of different diameters. For example, two second circular contacts consist of a center contact and one annular contact; two second circular contacts consist of two annular contacts of different diameters; three second circular contacts consist of one center contact and two annular contacts of different diameters; three second circular contacts consist of three annular contacts of different diameters, and so on.

[0120] The center contact and the annular contacts of different diameters satisfy the following condition: the center or center point is located on the axis of the prosthesis locking pin.

[0121] The annular contacts form an enclosure around the center contact, and the larger diameter annular contacts form an enclosure around the smaller diameter annular contacts.

[0122] The second flexible contact type rotatable contact connector (second mating connector 61) includes a fourth insulating seat 611 installed in the lock body 331. The fourth insulating seat 611 is provided with a second spring pin 612 corresponding to the second round contact. The second spring pin 612 has the same length direction as the axial direction of the prosthetic locking post 23. The movable contact of the second spring pin 612 is oriented towards the second round contact 522 along the axial direction of the prosthetic locking post 23.

[0123] When the prosthetic locking pin 23 is inserted into the lock body 331, the second spring pin 612 can make contact with the second round contact 522, thereby achieving a conductive connection.

[0124] For example, when there is a center contact and a ring contact, there is a second spring pin that elastically contacts the center contact (through the movable contact of the second spring pin and the internal spring) and a second spring pin that elastically contacts the ring contact.

[0125] After the prosthetic locking post 23 is inserted into place, the prosthetic locking post can be rotated and adjusted by the ring tooth 233 to adjust to the optimal force position, or to correct the rotational offset that occurs during use and walking. The second ring connector and the second elastic contact rotatable contact connector can maintain a conductive connection during rotation. The mating clearance between the gear and the locking gear row can also be maintained by the second ring connector and the second elastic contact rotatable contact connector within a set axial range.

[0126] In some embodiments, the lock body 331 is provided with an axial adjustment slide rail 336, the axial adjustment slide rail 336 is provided with a slide block 337, and the axial adjustment slide rail 336 is also provided with an elastic element 338. The fourth insulating seat 611 is mounted on the slide block 337.

[0127] When the slide 337 moves toward the distal end, the elastic element 338 is subjected to elastic deformation or aggravated elastic deformation by the combined action of the slide 337 and the axial adjustment slide rail 336.

[0128] See Figure 1 Moving upwards indicates movement towards the proximal end, while moving downwards indicates movement towards the distal end.

[0129] When the prosthetic locking pin 23 is inserted into the lock body 331 and forms a pressing force on the fourth insulating seat 611 (the second spring pin thereon): the continuous insertion of the prosthetic locking pin 23 correspondingly drives the fourth insulating seat 611 (based on the cooperation of the slide and the axial adjustment slide rail) to move in the distal direction to suit the insertion of the prosthetic locking pin 23 into place.

[0130] In some embodiments, the elastic element 338 is, for example, a helical compression spring or a helical tension spring.

[0131] For example, one end of the helical compression spring is pressed by the slide block, and the other end of the helical compression spring is pressed by the end face of the axial adjustment slide rail.

[0132] In some embodiments, the locking gear 232 can be adapted to different insertion depths of the prosthetic locking post, provided that the locking gear 232 can engage with the gear 3324.

[0133] In some embodiments, the prosthetic locking post 23 is replaceable.

[0134] In some embodiments, the prosthetic locking post 23 can be replaced with different lengths to meet different usage needs. In particular, it can be replaced with a prosthetic locking post with a different length of locking tooth row 232.

[0135] In some embodiments, the power lines and / or signal lines on the second electrical module 7 may be connected to the second spring pin or to different second spring pins.

[0136] In some embodiments, the first connection circuit 5 and the second connection circuit 6 are configured to connect the same power lines and signal lines on the first electrical module 4 and the second electrical module 7.

[0137] In some embodiments, one end of the same line of the first connection line is connected to the first circular contact, and the other end of the same line is connected to the second circular contact, so as to enable the first circular contact to communicate with the corresponding second circular contact.

[0138] In some embodiments, the prosthetic locking post 23 may extend from the proximal end of the flexible bushing 21 toward the distal end of the flexible bushing, thereby forming the axial direction of the corresponding prosthetic locking post.

[0139] In some embodiments, the prosthesis socket 31 is a generally rigid outer sleeve (typically made of thermoplastic material or resin laminate).

[0140] The flexible sleeve 21 can be worn on the patient's residual limb and can be accommodated within the basically rigid outer sleeve. The prosthesis socket 31 can provide good support for the patient's residual limb and is suitable for the force applied by the patient's residual limb; and when it is necessary to insert the prosthesis socket 31 into the patient's residual limb and the flexible sleeve and expel the air in the socket to form a negative pressure, it provides shape retention to maintain negative pressure adsorption.

[0141] In some embodiments, the prosthesis socket 31 may be made of thermoplastic materials such as PE (polyethylene) or PP (polypropylene).

[0142] Preferably, the prosthesis socket 31 can be made of PE material, which has a lower softening temperature, making it easier to test and shape the prosthesis socket under force (based on the patient's feedback on the force and comfort after wearing the prosthesis, the corresponding part of the prosthesis socket is heated and softened and then force is applied to adjust it to a suitable shape). At the same time, it has good insulation properties, which can prevent leakage of electrical connection circuits through the prosthesis socket, effectively ensuring the safety of the patient.

[0143] In some embodiments, the locking portion 33 may be connected to one or more prosthetic portions (e.g., knee joint components and / or upright components).

[0144] In some embodiments, the prosthesis portion includes a knee joint assembly 8, a first connection assembly 9 for connecting the knee joint assembly 8 to the locking portion, an upright assembly 10, a second connection assembly 11 for connecting the upright assembly 10 to the knee joint assembly, and a prosthesis ankle / foot assembly 12 for connecting the prosthesis ankle / foot assembly 12 to the upright assembly, and a third connection assembly 13 for connecting the prosthesis ankle / foot assembly 12 to the upright assembly.

[0145] In some embodiments, the first connection component 9 may include: A first frustum-shaped plug is installed at the far end of the lock body 331, with the large base of the first frustum-shaped plug located at the far end of the first frustum-shaped plug. A second frustum-shaped plug is installed at the proximal end of the knee joint assembly 8, with the large base of the second frustum-shaped plug located at the proximal end of the second frustum-shaped plug. The connecting sleeve has an insertion channel for accommodating frustum-shaped plugs (first and second).

[0146] The outer circumferential surface of the connecting sleeve has a proximal positioning screw hole and a distal positioning screw hole that connect to the insertion channel.

[0147] After the first frustum-shaped plug is inserted into place from the near end of the connecting sleeve, a screw can be driven into the positioning screw hole at the near end. The screw is inserted into the insertion channel to abut against the inclined surface of the first frustum-shaped plug, thereby preventing the first frustum-shaped plug from coming out of the insertion channel.

[0148] Similarly, after the second frustum-shaped plug is inserted into place from the far end of the connecting sleeve, a screw can be driven into the positioning screw hole at the far end. The screw is inserted into the insertion channel to abut against the inclined surface of the second frustum-shaped plug, thereby preventing the second frustum-shaped plug from coming out of the insertion channel.

[0149] The second and third connecting components can draw on the connecting structure of the first connecting component, or use other connecting structures to achieve their connecting function.

[0150] Knee joint component 8 is used to simulate the human knee joint and can be understood as a knee joint prosthesis. It typically has a certain degree of rotation. Figure 3The diagram shows a rotating structure that allows it to rotate at a certain angle.

[0151] The prosthetic ankle / foot component 12 is used to simulate the human ankle / foot and can be understood as an ankle / foot prosthesis. It typically has a wider force-bearing support surface to provide better support when the patient steps down with the aid of the prosthetic device.

[0152] In some embodiments, the prosthetic locking post 23 is conductive, for example, a structural component with good rigidity made of materials such as stainless steel, copper, or cast steel. As part of the connection wiring, the prosthetic locking post can also reduce the amount of overall wiring used.

[0153] In some embodiments, the connection and conduction of the first electrical module, the first connecting circuit, the second connecting circuit, and the second electrical module formed by "the connection between the prosthetic locking pin and the rigid threaded part, and the engagement by the locking part after the prosthetic locking pin is inserted into the locking part" can also be used to detect whether each component is installed in place. For example, if the threaded end of the prosthetic locking pin is not screwed in properly, the first round contact will not contact the first spring pin, causing that part of the circuit to be disconnected. The control unit will then issue an alarm based on the detection feedback. For example, alarm information can be sent to the user terminal device through a configured wireless module, or a light alarm can be issued through a configured light module.

[0154] In some embodiments, the first electrical module 4 disclosed in this invention includes, but is not limited to, at least one of the following units for acquiring signals: Bioelectric sensing unit (may include bioelectric sensors, such as electromyography (EMG)), human proximity sensing unit (may include human proximity sensors), infrared sensing unit (may include infrared sensors), temperature sensing unit (may include temperature sensors), and pressure sensing unit (may include pressure sensors, such as thin-film pressure sensors).

[0155] In some embodiments, the first electrical module 4 disclosed in this invention includes, but is not limited to, at least one of the following units for output: Heating unit (such as including heating wire and / or far-infrared lamp), vibration unit (such as including vibration motor).

[0156] In some embodiments, the second electrical module 7 can be a live electrical module, that is, when the first electrical module 4 needs power, the second electrical module 7 can provide power output to the first electrical module 4.

[0157] For example, the power supply unit of the second electrical module 7 has a battery-powered and / or rechargeable and / or replaceable battery.

[0158] In other embodiments, this disclosure also includes other methods of connection and power acquisition, such as the power supply unit of the second power module 7 being connected to an external socket or external jack via a plug to acquire power, such as being connected to an external charging connector via a charging port to acquire power, or acquiring power through different forms of connection and power acquisition such as magnetic interface connection, wireless charging, etc.

[0159] In some embodiments, the second electrical module 7 may further include a control unit.

[0160] In some embodiments, the second electrical module 7 further includes output units (such as lights, displays), input units (such as buttons), etc.

[0161] In some embodiments, the second electrical module 7 further includes a wireless unit, which can wirelessly interact with the user terminal device to facilitate the user to receive corresponding data and / or perform wireless control.

[0162] In some embodiments, the second electrical module, for example, controls the output unit of the first electrical module to output user-related actions by receiving user input signals. For instance, it receives a massage signal input by the user via a button or wireless unit and controls the vibration unit of the first electrical module to output a vibration massage action. Or, it receives a heat therapy signal input by the user via a button or wireless unit and controls the heating unit of the first electrical module to output a heating action.

[0163] In some embodiments, the second electrical module receives user-related signals acquired by the signal acquisition unit of the first electrical module, calculates and obtains corresponding detection results. For example, it detects the temperature data of the flexible liner through a temperature sensing unit, calculates the temperature value at the corresponding location, and then makes corresponding controls. For example, it controls heating when the temperature is too low in winter, or controls reducing the heating power or stopping heating when the heat therapy temperature is too high. For example, a pressure sensor detects the pressure value between the flexible liner and the patient's residual limb. If the calculated pressure is too low (below a preset pressure threshold), it alerts the user to the risk of loosening; or if the calculated pressure is too high (above a preset pressure threshold), it alerts the user to the risk of excessive compression, prompting the user to adjust or replace the flexible liner in a timely manner. For example, a bioelectric sensing unit continuously acquires the bioelectric signals of the patient's residual limb to assist the user in assessing the health of the patient's residual limb.

[0164] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
