Abstract
The utility model relates to a protractor for range of motion of finger joints, which can fast and accurately measure range of motion of finger joints. The protractor consists of a fan-shaped protractor graduated disc (1), a movable arm (2) and a pointer (3) which are connected through a rotating shaft (4). The included angle of the fan-shaped graduated disc is 150 degrees, a fixing arm (5) is arranged on one side of the fan-shaped graduated disc, and the fan-shaped graduated disc is provided with a horizontal base convenient for holding and fixing back sides of finger joints. The movable arm (2) and the pointer (3) are integrated, the included angle between the movable arm (2) and the pointer (3) is 150 degrees, and the length of the movable arm (2) is not longer than 3cm. The fixing arm (5) of the fan-shaped graduated disc (1) can be placed on the back side of a near finger joint of an operator, the movable arm (2) is attached to the back side of a far-side finger joint of the operator, and then scale pointed to the fan-shaped graduated disc (1) by the pointer (3) is the angle of the finger joint of the operator.
Description
Technical field: this utility model patent relates to the clinical function evaluation areas, can measure the mobility of finger-joint.
Background technology: accurately and efficiently measure the range of activity of finger-joint, the clinical reliable functioning appreciation information that provides can be provided.There is following problem in the articulation amount hornwork of present clinical use: 1. finger is more very thin, and the protractor that uses at present is all more clumsy, and the fixed arm of protractor and transfer arm are difficult for fixing with the dactylus axis of finger.2. the axle center of protractor is difficult for locating mutually with the finger-joint axle center.Above-mentioned 2 reasons all cause measurement result accuracy and repeatable poor.3. when measuring interphalangeal joint mobility far away, general quantity hornwork transfer arm is long and since palmar hand stop the operation that influence is measured.4. it is good to work as the finger-joint pliability, when having the hyperextension angle, because stopping of protractor graduated disc causes the hyperextension angle that can't measure the joint.Thereby the clinical protractor that presses for a kind of special use and the measurement of finger-joint mobility.
This utility model content:
This utility model purpose is to provide a kind of protractor of accurate measurement finger-joint mobility.
The technical scheme of this utility model technical solution problem is:
1. design angle is 150 ° a fan dial (1), and the center of circle of fan dial is rotating shaft (4) place, and the fixed arm (5) on the graduated disc (1) is fixed on nearly joint dactylus dorsal part, makes joint dactylus far away that 30 ° hyperextension activity space be arranged.
2. what adapt with said structure is the integrated design of transfer arm (2) and pointer (3), 150 ° of angles are arranged between the two, guarantee that transfer arm (2) is placed on joint dactylus dorsal part far away, when measuring 30 ° of scopes of interphalangeal joint hyperextension with interior angle, pointer can not exceed the fixed arm (5) on the graduated disc (1).
3. 0 ° of scale of design fan dial (1) is positioned at 30 ° of scale positions of normal amount hornwork, to satisfy the needs of said structure design.That is when transfer arm becomes 180 ° with fixed arm (5), become the pointer at 150 ° of angles just in time to refer on 0 ° of scale position of fan dial with transfer arm.
4. transfer arm of protractor (2) and fixed arm (5) all have a horizontal base, make transfer arm (2) and fixed arm (5) one stable contact surface to be arranged with finger dactylus dorsal part, are easy to fix, and determine axle center, joint and axis.
5. the transfer arm of design flow hornwork (2) length is 3cm.
The beneficial effects of the utility model:
Use this utility model patent to carry out the finger-joint mobility and measure, have convenient, fast, advantages such as accuracy rate is high, favorable repeatability.
Description of drawings:
Further specify below in conjunction with accompanying drawing:
1. angle is 150 ° a fan dial (1), and the one side has horizontal base, is fixed arm (5)
2. transfer arm (2) and pointer (3) are one, between 150 ° of angles are arranged,
3. the joining place of transfer arm (2) and pointer (3) is the axle center, links to each other by rotating shaft (4) with the fan dial axle center
4. transfer arm (2) length should not surpass 3cm.
The specific embodiment:
With reference to accompanying drawing, how to use the finger-joint protractor in conjunction with actual implementation method explanation.
The operator is placed on the fixed arm (5) on the fan dial (1) dorsal part of nearside dactylus, rotating shaft (4) is placed on the joint dorsal part, transfer arm (2) then fits with the dorsal part of distally dactylus, and reading pointer (3) is gone up indicated scale at fan dial (1), can obtain the angle in joint.
Claims (4)
1. the protractor of a human finger range of motion is characterized in that segmental protractor graduated disc (1) links to each other by rotating shaft (4) with transfer arm (2), pointer (3).
2. finger-joint mobility protractor according to claim 1, its fan dial (1) has following feature: 1. the fan dial angle is 150 °; 2. be its fixed arm (5) with fan dial (1) one side, a horizontal base is arranged; 3. 0 ° of scale of fan dial (1) is positioned at 30 ° of scale positions of normal amount hornwork; 4. the center of circle of fan dial is rotating shaft (4) place.
3. finger-joint mobility protractor according to claim 1, its transfer arm (2), pointer (3) have following feature: transfer arm (2) and pointer (3) they are one, form 150 degree angles between the two, both joining places are rotating shaft (4) place.
4. finger-joint mobility protractor according to claim 1, fan dial (1) links to each other by rotating shaft (4) with transfer arm (2), pointer (3).
