Abstract
The utility model discloses an artificial movable finger composed of a fixed finger, a slave cylinder and an actuating cylinder, wherein the slave cylinder (5) is connected with the actuating cylinder (4) through an oil channel (6); the fixed finger is composed of a front end finger knuckle (1), a middle finger knuckle (2) and a rear supporting body (3), each finger knuckle is hinged, the middle finger knuckle has one or two knuckles, the slave cylinder is arranged on the middle finger knuckle, and the slave cylinder or the actuating cylinder is arranged on the rear supporting body; the front end of a cylinder rod of the slave cylinder presents an included angle and is hinged with a connecting rod (7), and the front end of the connecting rod is fixedly connected with the finger knuckle arranged in the front. The utility model utilizes the hydraulic transmission principle, the actuating cylinder arranged on the movable finger drives the slave cylinder arranged on the fixed finger to act, thereby the fixed finger is driven to achieve the purposes of bending or unbending, in addition, the utility model has simple structure, flexible and convenient use and no need of other energy sources. The range of application is wide, no matter partial or whole finger is lost, the finger can be still used.
Description
Technical field
This utility model belongs to the prosthesis technique field, and what relate generally to is a kind of artificial movable finger.
Background technology
The incompleteness of finger not only can be brought many inconvenience to life, and influences the people of allowing attractive in appearance and produce the psychology of feeling oneself inferior.Existing artificial finger has two kinds: early stage artificial finger is Immobile mostly, its design still be confined to attractive in appearance on, remedy the incomplete shortcoming of finger, seldom relate to the function of use of finger.Patent documentation disclosed " artificial finger " (patent No.: 200620010155.4) make the definiteness of installation realize its function of use, but owing to it is realized by hinge, stay cord, spring etc. are set, so its complex structure, a little less than the motility relatively.
Summary of the invention
The purpose of this utility model is to propose a kind of artificial movable finger.Make it easy to use flexibly, simple in structure.
This utility model realizes that the technical scheme that above-mentioned purpose is taked is: it is made of definiteness, slave cylinder, actuating cylinder, and slave cylinder is connected by oil circuit with actuating cylinder; Described definiteness is made of front end dactylus, middle dactylus and rear support, and each knucklejoint connects, and middle dactylus is a joint or two joints, and described middle dactylus is provided with slave cylinder, and rear support is provided with slave cylinder or actuating cylinder; The piston rod front end of slave cylinder and actuating cylinder is angle and all is hinged with connecting rod, the front end of described connecting rod be positioned at forward dactylus and fixedly connected.
This utility model utilizes hydraulic transmission principle, drive the slave cylinder action that is placed on the definiteness by the actuating cylinder that is placed on moving the finger, realize function crooked or that stretch, have simple in structure thereby drive definiteness, flexible and convenient to use, need not prepare other energy.Applied widely, no matter lose part finger or the whole finger that refers to all can use.

Among the figure: 1, front end dactylus, 2, middle dactylus, 3, rear support, 4, actuating cylinder, 5, slave cylinder, 6, oil circuit, 7, connecting rod, 8, the moving finger.
The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in Figure 1: operation principle of the present utility model is: actuating cylinder 4 or slave cylinder 5 are the through-rod piston oil cylinder, slave cylinder 5 or actuating cylinder 4 are the single-rod piston oil cylinder, and two hydraulic fluid ports of the E on the through-rod piston oil cylinder, G are connected with two hydraulic fluid ports of F, H on the single-rod piston oil cylinder respectively.As the power F who makes progress of hydraulic stem that gives the through-rod piston oil cylinder, the hydraulic oil in the A chamber is under pressure and flows to the B chamber, and the hydraulic stem that hydraulic oil promotes the single-rod piston oil cylinder moves upward, and the hydraulic oil in D chamber is under pressure and flows to the C chamber simultaneously.Otherwise give the downward power of hydraulic stem of through-rod piston oil cylinder, the hydraulic stem of single-rod piston oil cylinder moves downward.According to this principle, just can drive a plurality of slave cylinder work during application by an actuating cylinder.
As shown in Figure 2: the described definiteness of present embodiment can be any residual finger (as thumb, forefinger, middle finger, the third finger, little finger of toe), it is made of front end dactylus 1, middle dactylus 2 and rear support 3, middle dactylus is a joint or two joints, and the connecting portion of each dactylus bottom is the inclined-plane.Each knucklejoint connects, and makes definiteness realize action crooked or that stretch.On middle dactylus, all be hingedly connected with slave cylinder 5 (it can be arranged on inside or outside), be angle at the piston rod front end of slave cylinder 5 and be hinged with connecting rod 7, the front end of connecting rod 7 be positioned at forward dactylus and fixedly connected, drive the dactylus action thus---crooked or stretch.Slave cylinder 5 and actuating cylinder 4 be provided with quantity can according to the situation of residual finger promptly in the middle of the quantity of dactylus determine; When middle dactylus is a joint, a slave cylinder 5 and an actuating cylinder 4 are set; When middle dactylus was 2 whens joint, two slave cylinders 5 and actuating cylinder 4 or three slave cylinders 5 and two actuating cylinders 4 are set.Be hingedly connected with slave cylinder 5 or actuating cylinder 4 on rear support 3, promptly when middle dactylus was a joint, what be provided with on it was actuating cylinder 4; When middle dactylus was 2 whens joint, setting is slave cylinder 5 or actuating cylinder 4 it on, promptly be provided with on the rear support be slave cylinder 5 time, actuating cylinder 4 is installed on the adjacent moving finger.Rear support 3 can be installed according to the situation of residual finger, can be positioned at position, residual finger, the back of the hand position or wrist position.Slave cylinder 5 is connected by oil circuit 6 with actuating cylinder 4, drives its action by actuating cylinder 4.
Be that example is elaborated with three joint dactylus below:
As Fig. 3 in conjunction with shown in Figure 4, the middle dactylus of its definiteness is two joints, slave cylinder 5 all is set on middle dactylus, actuating cylinder 4 is set on rear support 3, during use, rear support 3 is enclosed within position, residual finger, the actuating cylinder 4 on the rear support 3 is under the moving effect that refers to 8 bending or stretch, make the piston rod action that hydraulic oil is driven slave cylinder 5 actions by oil circuit 6 and make the dactylus synchronization action, recover the crooked of residual finger or stretch function.
