Abstract
The utility model relates to a fully-mechanical functional compensation artificial finger comprising a first knuckle, a small knuckle connecting rod, a second knuckle, an upper connecting shaft, a lower connecting shaft, a middle knuckle connecting rod, a middle knuckle driving rod, a disabled finger lantern ring, a fixed clamp and a connecting block, wherein the first knuckle is respectively and movably connected with the front ends of the small knuckle connecting rod and the second knuckle, the back ends of the small knuckle connecting rod and the second knuckle are respectively connected with the front ends of the middle knuckle connecting rod and the middle knuckle driving rod by the upper connecting shaft and the lower connecting shaft, the back ends of the middle knuckle connecting rod and the middle knuckle driving rod are respectively connected with the connecting block and the disabled finger lantern ring, and the connecting block is fixed on the fixed clamp. The humanoid artificial finger for disabled persons, which can simply carry out grabbing movement through a self force source in advance, carries out humanoid practical design at the aspects of the appearance, the movement form and the like, thereby having the grabbing function of a human-body finger and small size, the appearance approaches to the size of the human-body finger, and the artificial finger is mainly used for patients with proximal phalanxes amputated by above 1/3.
Description
Technical field
This utility model relates to a kind of human body prosthetic finger of medical apparatus and instruments, especially relates to a kind of bionic finger that can simulate the human finger multi joint motion, and this finger utilizes three groups of linkages to realize grip function.
Background technology
The research that apery type people with disability does evil through another person is for the quality of life of improving the people with disability and promotes the social rehabilitation career development that this research has become a focus of biomedical engineering and robot subject.Since the nineties in 20th century, the intelligent Dextrous Hand with accurate extracting and operation occurs in succession, and as NASA humanoid dextrous hand, DLR humanoid dextrous hand, this class hands is background with the spatial operation, has multiple perceptive function, degree of intelligence height, system complex.On this basis, the man-shaped hand of in light weight, simple in structure, many fingers emerges in succession as Southampton hands, TBM hands, OTTOBOCK hands etc.Such is done evil through another person and has the feature that well personalizes aspect profile and the weight, but for the most of people with disability's of China practical situation, economy necessarily can't afford.
Summary of the invention
This utility model is to provide a kind of full mechanical function compensatory prosthetic finger, that this mechanical prosthetic hand refers to is simple in structure, in light weight, can realize the apery type artificial finger for disabled person of finger grasping movement by self power source (proximal phalanx bends and stretches), this finger can be used for the patient of single finger amputation, and is compensatory by the function of amputated finger.
For achieving the above object, the technical scheme of this novel employing is: the compensatory prosthetic finger of a kind of full mechanical function, comprise first articulations digitorum manus, little joint connecting rod, second articulations digitorum manus, on, following connecting axle, middle articulations digitorum manus connecting rod, middle articulations digitorum manus drive rod, residual finger sleeve ring, fixation clamp, contiguous block, be characterized in: first articulations digitorum manus flexibly connects with the little joint connecting rod and the second articulations digitorum manus front end respectively, the little joint connecting rod and the second articulations digitorum manus rear end are respectively by last, following connecting axle is connected with middle articulations digitorum manus drive rod front end with middle articulations digitorum manus connecting rod, middle articulations digitorum manus connecting rod is connected with residual finger sleeve ring with contiguous block respectively with middle articulations digitorum manus drive rod rear end, and contiguous block is fixed on the fixation clamp.
The present invention compares with the existing product of doing evil through another person, and has the following advantages and beneficial effect:
(1) can be by the end motion of finger stub, the nearly interphalangeal joint that drives finger is synchronized with the movement with interphalangeal joint far away, the grasping movement of simulation human body real finger;
(2) can carry out Transform Type design easily according to patient's finger length, realize personalized customization.
(3) overcome the dead unit problem of present stage existing procucts mechanism
(4) simple in structure, ingenious, practical.

The specific embodiment
Below in conjunction with accompanying drawing and example this utility model is further described
Extremely shown in Figure 5 as Fig. 1, the compensatory prosthetic finger of full mechanical function of the present utility model, comprise first articulations digitorum manus 1, little joint connecting rod 2, second articulations digitorum manus 3, upper and lower connecting axle 4,5, middle articulations digitorum manus connecting rod 6, middle articulations digitorum manus drive rod 7, residual finger sleeve ring 8, fixation clamp 9, contiguous block 10.
First articulations digitorum manus flexibly connects with little joint connecting rod 2 and second articulations digitorum manus, 3 front ends respectively, little joint connecting rod 2 and second articulations digitorum manus, 3 rear ends are respectively by upper and lower connecting axle 4,5 are connected with middle articulations digitorum manus drive rod 7 front ends with middle articulations digitorum manus connecting rod 6, middle articulations digitorum manus connecting rod 6 is connected with residual finger sleeve ring 8 with contiguous block 10 respectively with middle articulations digitorum manus drive rod 7 rear ends, and contiguous block 10 is fixed on the fixation clamp 9.
The kind of drive of the present utility model:
Fixation clamp 9 is fixed on the preceding palm of residual finger, the also fixing thereupon middle articulations digitorum manus drive rod 7 of motion that is driven residual finger sleeve ring 8 by residual finger of the contiguous block 10 that has been fixed on rotates with the rotating shaft that is connected of contiguous block 10 around it, rotate with the rotating shaft that is connected of middle articulations digitorum manus connecting rod 6 around it thereby drive little joint connecting rod 2, the rotation of little joint connecting rod 2 can make first articulations digitorum manus 1 rotate with the rotating shaft that is connected of second articulations digitorum manus 3 around it.
Claims (1)
1. compensatory prosthetic finger of full mechanical function, comprise first articulations digitorum manus (1), little joint connecting rod (2), second articulations digitorum manus (3), on, following connecting axle (4,5), middle articulations digitorum manus connecting rod (6), middle articulations digitorum manus drive rod (7), residual finger sleeve ring (8), fixation clamp (9), contiguous block (10), it is characterized in that: described first articulations digitorum manus (1) flexibly connects with little joint connecting rod (2) and second articulations digitorum manus (3) front end respectively, little joint connecting rod (2) and second articulations digitorum manus (3) rear end are respectively by last, following connecting axle (4,5) be connected with middle articulations digitorum manus drive rod (7) front end with middle articulations digitorum manus connecting rod (6), middle articulations digitorum manus connecting rod (6) is connected with residual finger sleeve ring (8) with contiguous block (10) respectively with middle articulations digitorum manus drive rod (7) rear end, and contiguous block (10) is fixed on the fixation clamp (9).
