Description

Technical Field

[0001] The utility model relates to the technical field of prosthetics, and particularly relates to an induction limb end joint and a prosthetic limb. Background Art

[0002] The limb end joint is located at the end of a limb. For example, the distal phalanx of a finger belongs to the limb end joint and usually has a sensing ability. By configuring sensors on the limb end joint, the limb end joint of a prosthetic limb can have a sensing function. In the prior art, when multiple sensors are configured on the limb end joint of a prosthetic limb, the distance between the multiple sensors is relatively close, and they may interfere with each other, thereby reducing the accuracy of sensing.

[0003] Therefore, the prior art still needs to be improved and developed. Summary of the Utility Model

[0047] To make the objectives, technical solutions and advantages of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0048] Please refer to Figures 1-6 simultaneously. The present utility model provides some preferred embodiments of a sensing limb tip.

[0049] As Figure 1 and Figure 2As shown, the sensing limb distal segment includes:

[0050] A limb distal segment body 10, having a limb tip portion and a limb side portion;

[0051] A limb tip sensing assembly 20, disposed at the limb tip portion;

[0052] A limb side sensing assembly 30, disposed at the limb side portion;

[0053] A barrier member 40, disposed on the limb distal segment body 10 and located between the limb tip sensing assembly 20 and the limb side sensing assembly 30.

[0054] Specifically, the limb distal segment of an animal usually has a sensing or perceiving function, which is specifically realized by multiple sensors or receptors. The limb distal segment body 10 refers to the outermost segment of a prosthetic limb. The limb distal segment body 10 includes a distal phalanx or a distal toe phalanx. The limb tip portion refers to the tip part of the limb distal segment body 10, and the limb side portion refers to the side part of the limb distal segment body 10. In order to broaden the application range of the limb distal segment, a limb tip sensing assembly 20 is disposed at the limb tip portion, a limb side sensing assembly 30 is disposed at the limb side portion, and the barrier member 40 is located between the limb tip sensing assembly 20 and the limb side sensing assembly 30 to separate the two. The sensing of the limb tip sensing assembly 20 and the sensing of the limb side sensing assembly 30 are independent of each other and do not affect each other. Then, the position of the sensed object can be accurately determined through the limb tip sensing assembly 20 or the limb side sensing assembly 30.

[0055] In a preferred embodiment of the present invention, the limb tip sensing assembly 20 can adopt a capacitive sensing assembly, a resistive sensing assembly or an inductive sensing assembly, and the limb side sensing assembly 30 can adopt a capacitive sensing assembly, a resistive sensing assembly or an inductive sensing assembly. The limb tip sensing assembly 20 and the limb side sensing assembly 30 can sense an object approaching or contacting.

[0056] In a preferred embodiment of the present invention, please refer to Figure 1 and Figure 6 simultaneously, the limb tip sensing assembly 20 includes:

[0057] A first sensor 21, disposed at the limb tip portion;

[0058] A first sensing object 22, disposed at the limb tip portion.

[0059] Specifically, the first sensor 21 is used to sense the first sensing object 22. When an object contacts the first sensing object 22, the first sensing object 22 generates a displacement, and thus is sensed by the first sensor 21.

[0060] In a preferred embodiment of the present invention, please refer to Figure 1 and Figure 6 simultaneously, the limb side sensing assembly 30 includes:

[0061] A second sensor 31, disposed on the limb side portion;

[0062] A second sensing object 32, disposed on the limb side portion.

[0063] Specifically, the second sensor 31 is used to sense the second sensing object 32. When an object contacts the second sensing object 32, the second sensing object 32 generates a displacement, and thus is sensed by the second sensor 31.

[0064] In a preferred embodiment of the present invention, please also refer to Figures 2-3 , the first sensing object 22 and the second sensing object 32 are respectively located on both sides of the barrier member 40; the angle between the first sensor 21 and the second sensor 31 is a right angle or an obtuse angle.

[0065] Specifically, the first sensing object 22 and the second sensing object 32 are separated by the barrier member 40. When an object contacts the first sensing object 22 and generates a displacement, the second sensing object 32 does not generate a displacement; when an object contacts the second sensing object 32 and generates a displacement, the first sensing object 22 does not generate a displacement. The angle between the first sensor 21 and the second sensor 31 is a right angle or an obtuse angle. The first sensor 21 and the first sensing object 22 both correspond to the limb tip portion, the second sensor 31 and the second sensing object 32 both correspond to the limb side portion, and the first sensor 21 and the second sensor 31 face different directions, so that objects in different directions can be detected.

[0066] In a preferred embodiment of the present invention, please also refer to Figures 2-3 , the first sensing object 22 and the second sensing object 32 are connected by a connecting layer 50.

[0067] Specifically, a connecting layer 50 is disposed outside the barrier member 40. The connecting layer 50 connects the first sensing object 22 of the limb tip sensing assembly 20 and the second sensing object 32 of the limb side sensing assembly 30 respectively, so that the integrity of the sensing limb terminal is better and the prosthetic simulation effect is better. The connecting layer 50 adopts a layer structure with a relatively thin thickness.

[0068] In a preferred embodiment of the present invention, both the first sensing object 22 and the second sensing object 32 are deformed under pressure to form displacements; the first sensor 21 is used to sense the displacement of the first sensing object 22; the second sensor 31 is used to sense the displacement of the second sensing object 32.

[0069] Specifically, when an object contacts the first inductor 22, the first inductor 22 contacts the object, is deformed under pressure, and forms a displacement. The first sensor 21 can sense the displacement of the first inductor 22. When an object contacts the second inductor 32, the second inductor 32 contacts the object, is deformed under pressure, and forms a displacement. The second sensor 31 can sense the displacement of the second inductor 32.

[0070] In a preferred embodiment of the present invention, please refer to Figure 2 and Figure 6 simultaneously. The first inductor 22 and the second inductor 32 both include:

[0071] An insulating layer 221;

[0072] A conductor 222, disposed inside the insulating layer 221;

[0073] Both the first sensor 21 and the second sensor 31 adopt capacitive sensors.

[0074] Specifically, the insulating layer 221 is disposed at the end of the sensing limb. The insulating layer 221 of the first inductor 22 is disposed at the tip of the limb, and the insulating layer 221 of the second inductor 32 is disposed at the side of the limb. The conductor 222 is disposed inside the insulating layer 221 and faces the corresponding sensor. When the insulating layer 221 contacts an object, the insulating layer 221 drives the conductor 222 to move towards the corresponding sensor, and thus is sensed by the corresponding sensor. The first sensor 21 and the second sensor 31 can adopt capacitive sensors, resistive sensors, or inductive sensors. Preferably, the first sensor 21 and the second sensor 31 adopt capacitive sensors.

[0075] In a preferred embodiment of the present invention, please refer to Figures 2-3 simultaneously. The connecting layer 50 includes:

[0076] An insulating connecting layer 51, respectively connecting the insulating layer 221 of the first inductor 22 and the insulating layer 221 of the second inductor 32.

[0077] Specifically, the connection layer 50 can only connect the insulating layer 221 of the first inducer 22 and the insulating layer 221 of the second inducer 32. The conductors 222 of the first inducer 22 and the conductors 222 of the second inducer 32 are spaced apart from each other and not electrically connected. When both the first inductor 21 and the second inductor 31 are capacitive inductors, a capacitance is also formed between the conductors 222 of the first inducer 22 and the conductors 222 of the second inducer 32, so that the first inductor 21 and the second inductor 31 can form a mutual capacitance group. When a conductive object approaches the first inducer 22 or the second inducer 32, the capacitance data of the first inductor 21 or the second inductor 31 changes, thereby sensing the approaching conductive object. The insulating connection layer 51, the insulating layer 221 of the first inducer 22, and the insulating layer 221 of the second inducer 32 are integrally formed.

[0078] In a preferred embodiment of the present invention, please also refer to Figures 2-3 , the connection layer 50 further includes:

[0079] A conductor connection layer 52 that respectively connects the conductor 222 of the first inducer 22 and the conductor 222 of the second inducer 32.

[0080] Specifically, the conductors 222 of the first inducer 22 and the conductors 222 of the second inducer 32 can be connected by the conductor connection layer 52, so that no capacitance is formed between the conductors 222 of the first inducer 22 and the conductors 222 of the second inducer 32. The two are connected by the conductor connection layer 52, and a more reliable structure can be formed. The conductor connection layer 52, the conductor 222 of the first inducer 22, and the conductor 222 of the second inducer 32 are integrally formed.

[0081] In a preferred embodiment of the present invention, please also refer to Figure 2 and Figure 6 , the conductor 222 is provided with a protrusion 223; the protrusion of the second inducer 32 includes: a first protrusion 321, and a sinking groove 323 is formed around the first protrusion 321.

[0082] Specifically, the conductor 222 is provided with a protrusion 223, and the protrusion 223 faces the corresponding inductor. The protrusion of the second inducer 32 includes a first protrusion 321. A sinking groove 323 is formed around the first protrusion 321 on the conductor 222. The thickness of the conductor 222 in the peripheral area of the first protrusion 321 is thinner, so that the first protrusion 321 is more likely to form a displacement.

[0083] In a preferred embodiment of the present invention, please also refer to Figure 2 and Figure 6, the protrusion of the second inductor 32 further includes: a second protrusion 322; the diameter of the second protrusion 322 is smaller than the diameter of the first protrusion 321.

[0084] Specifically, the protrusion of the second inductor 32 further includes a second protrusion 322, and the diameter of the second protrusion 322 is smaller than the diameter of the first protrusion 321. A sink 323 may not be formed around the second protrusion 322 on the conductor 222.

[0085] In a preferred embodiment of the present invention, please refer to Figures 4-5 , the barrier 40 includes:

[0086] a first base 41 and a second base 42, both disposed on the distal phalanx body 10;

[0087] a wedge portion 43, the large end of the wedge portion 43 connecting the first base 41 and the second base 42;

[0088] wherein, the small end of the wedge portion 43 is curved.

[0089] Specifically, the first base 41 and the second base 42 are spaced apart on the distal phalanx body 10, and the first base 41 and the second base 42 are located on the side of the first protrusion 321. The wedge portion 43 has a large end and a small end, the large end is connected to the first base 41 and the second base 42, and the small end faces the connecting layer 50. The small end supports the connecting layer 50, and since the small end is curved, the fingertip sensing assembly 20 and the lateral sensing assembly 30 of the sensing distal phalanx can form a curved surface, and the prosthetic simulation effect is better.

[0090] Based on the sensing distal phalanx of any of the above embodiments, the present invention further provides a prosthetic limb, including the sensing distal phalanx described in any of the above embodiments, as specifically described above.

[0091] The prosthetic limb provided by the present invention has all the above beneficial effects due to the provision of the sensing distal phalanx described in any of the above technical solutions, and will not be elaborated herein.

[0092] It should be understood that the application of the present invention is not limited to the above examples. For those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present invention.
