Abstract
The utility model provides a hand draw gear, includes support frame, assembly pulley, finger drag loop, the support is connected with finger drag loop through the assembly pulley, finger drag loop is including connecting handle, pull ring and drag loop, and the drag loop lower extreme is provided with the opening, and the top is connected with the pull ring through connecting the handle, drag loop narrow toper tubular structure for down wide, and this drag loop comprises the diamond mesh form layer that two -layer interconnect can deform, and inlayer diamond mesh form in situ footpath is lighter than outer diamond mesh form in situ directly. The utility model overcomes tradition finger drag loop atress is uneven, very easily causes the technological problem of local extravasated blood, the toper tube -shape drag loop that makes through the diamond mesh form layer structure that adopts the bilayer to deform, thereby the frictional force that produces when turning into the deformation of diamond mesh form with trailing pulling force apply uniformly on patient's finger, greatly improved patient's recovery rate, treatment is tall and erect.
Description
Technical field
The utility model is related to aid in medical recovery instrument field, especially a kind of hand draw-gear.
Background technology
With the development and progress of medical technology, obtained with the minimally invasive theory that minimum wound exchanges optimum therapeuticing effect for
It is widely applied.The complication such as anchylosis, scar contracture, adhesion of tendon are easily formed after hand injury.Hand function traction branch
Tool can be by appropriate lasting external active force, and the generation of infectious-related complication is hindered in correction deformity or control, recovers the good of joint
Good mobility.Because the anatomical structure of hand is complicated, tradition traction equipment easily causes hand joint part when being drawn
Compression is excessive to cause extravasated blood to be formed, and has had a strong impact on patient outcomes, or even aggravate the state of an illness.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of reasonable in design, simple structure, is used
A kind of hand draw-gear convenient, that tractive force can be evenly distributed.
The purpose of this utility model is achieved through the following technical solutions：
A kind of hand draw-gear, including support frame, assembly pulley, finger traction casing, support frame as described above by assembly pulley with
Finger traction casing is connected, and the finger traction casing includes connection handle, draw ring and traction casing, and traction casing lower end is provided with out
Mouthful, top is connected by connection handle with draw ring, and the traction casing is low wide and up narrow taper tubular structure, and the traction casing is by two-layer
Be connected with each other can deformation diamond-mesh layer composition, and internal layer diamond-mesh layer internal diameter less than outer layer diamond-mesh layer internal diameter.
And, the two-layer can produce mutual displacement between the diamond-mesh layer of deformation.
And, also integrally make flange at the described traction casing opening.
And, support frame as described above top is additionally provided with retainer ring.
Advantage of the present utility model and economic effect are：
1st, the utility model overcomes conventional finger traction casing unbalance stress, easily causes the technical barrier of local extravasated blood,
By using it is double-deck can deformation the taper tubular traction casing that is made of diamond-mesh Rotating fields, the pulling force of traction is converted into rhombus
The frictional force produced during netted deformation drastically increases the resume speed of patient so as to be evenly applied on patient's finger,
Therapeutic effect is distinguished.
2nd, the utility model is cooperated by using support frame and assembly pulley, can be by the tractive force average mark of whole hand
It is fitted on each finger traction casing, reaches traction balance, it is to avoid single finger is towed the excessive formation extravasated blood of force.
Brief description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is the structural representation of the utility model finger traction casing；
Fig. 3 is the use state figure that the utility model finger traction casing coats finger；
Fig. 4 is the use state figure that the utility model finger traction casing lifts finger.
Specific embodiment
For content of the present utility model, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinate accompanying drawing
Describe in detail as follows.It should be noted that the present embodiment is descriptive, it is not limited, it is impossible to thus limit this practicality
New protection domain.
A kind of hand draw-gear, including support frame 6, assembly pulley 8, finger traction casing 9, support frame as described above pass through assembly pulley
It is connected with finger traction casing, the finger traction casing includes connection handle 2, draw ring with 1 and traction casing, and traction casing lower end is provided with
Opening, top is connected by connection handle with draw ring, and the traction casing is low wide and up narrow taper tubular structure, and the traction casing is by two
Layer be connected with each other can deformation diamond-mesh layer composition, and internal layer diamond-mesh layer 4 internal diameter less than outer layer diamond-mesh layer 3 in
Footpath.
And, the two-layer can produce mutual displacement between the diamond-mesh layer of deformation.At the described traction casing opening
Flange 5 is also integrally made.Support frame as described above top is additionally provided with retainer ring 7.
The utility model when in use, is first flattened for finger provides enough entrance spaces, then by hand the traction casing
Refer to that traction casing is fixed with assembly pulley, lifting, the internal layer rhombus net during lifting upwards are started after finger enters traction casing
Shape layer internal diameter is gradually tapered up and for pulling force to be converted into frictional force, and with the increase of lifting power, frictional force also incrementally increases to reach
To the purpose of traction.
