Abstract
A kind of hand draw-gear, including support frame, assembly pulley, finger traction casing, the support is connected by assembly pulley with finger traction casing, the finger traction casing includes connection handle, draw ring and traction casing, traction casing lower end is provided with opening, and top is connected by connection handle with draw ring, and the traction casing is low wide and up narrow taper tubular structure, the traction casing by be connected with each other for two layers can the diamond-mesh layer of deformation form, and internal layer diamond-mesh layer internal diameter is less than outer layer diamond-mesh layer internal diameter.Instant invention overcomes conventional finger traction casing unbalance stress, easily cause the technical barrier of local extravasated blood, by using it is double-deck can taper tubular traction casing made of the diamond-mesh Rotating fields of deformation, the pulling force of traction is converted into frictional force caused by diamond-mesh deformation so as to be evenly applied on patient's finger, the resume speed of patient is drastically increased, therapeutic effect is distinguished.
Description
Technical field
The present invention relates to auxiliary medical recovery instrument field, especially a kind of hand draw-gear.
Background technology
With the development and progress of medical technology, the minimally invasive theory for exchanging optimum therapeuticing effect for the wound of minimum obtains
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 local when being drawn
Be pressurized it is excessive cause extravasated blood to be formed, had a strong impact on patient outcomes, or even aggravate the state of an illness.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of reasonable in design, simple in construction, user
Just a kind of hand draw-gear of tractive force can, be evenly distributed.
The purpose of the present invention is achieved through the following technical solutions：
A kind of hand draw-gear, including support frame, assembly pulley, finger traction casing, the support pass through assembly pulley and hand
Referring to traction casing to be connected, the finger traction casing includes connection handle, draw ring 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 layers of phase
Connect can deformation diamond-mesh layer composition, and internal layer diamond-mesh layer internal diameter is less than outer layer diamond-mesh layer internal diameter.
Moreover, described two layers can produce mutual displacement between the diamond-mesh layer of deformation.
Moreover, the described traction casing opening has also integrally made flange.
Moreover, it is additionally provided with retainer ring at the top of support frame as described above.
Advantages of the present invention and economic effect are：
1st, instant invention overcomes conventional finger traction casing unbalance stress, the technical barrier of local extravasated blood is easily caused, is passed through
Using it is double-deck can taper tubular traction casing made of the diamond-mesh Rotating fields of deformation, the pulling force of traction is converted into diamond-mesh
Frictional force caused by deformation drastically increases the resume speed of patient, treated so as to be evenly applied on patient's finger
Effect is distinguished.
2nd, the present invention cooperates by using support frame and assembly pulley, can be evenly distributed to the tractive force of whole hand
On each finger traction casing, each finger amount of being pulled up is identical to reach traction balance purpose.Single finger is avoided to be towed
The excessive formation extravasated blood of force.
Brief description of the drawings
Fig. 1 is the front view of the present invention；
Fig. 2 is the structural representation of finger traction casing of the present invention；
Fig. 3 is the use state figure of finger traction casing cladding finger of the present invention；
Fig. 4 is the use state figure of finger traction casing lifting finger of the present invention.
Embodiment
For present disclosure, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinate accompanying drawing detailed
It is described as follows.It should be noted that the present embodiment is descriptive, it is not limited, it is impossible to thus limit the guarantor of the present invention
Protect scope.
A kind of hand draw-gear, including support frame 6, assembly pulley 8, finger traction casing 9, the support by assembly pulley with
Finger traction casing is connected, and the finger traction casing includes connection handle 2, draw ring is provided with out with 1 and traction casing, traction casing lower end
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 layers
Be connected with each other can deformation diamond-mesh layer composition, and the internal diameter of internal layer diamond-mesh layer 4 is less than the internal diameter of outer layer diamond-mesh layer 3.
Moreover, described two layers can produce mutual displacement between the diamond-mesh layer of deformation.The described traction casing opening
Flange 5 is also integrally made.Retainer ring 7 is additionally provided with the top of support frame as described above.
Enough entrance spaces are provided for finger in the use of the present invention, first flattening the traction casing, then lead finger
Draw set to fix with assembly pulley, start lifting upwards, the internal layer diamond-mesh layer during lifting after finger enters traction casing
Internal diameter gradually tapers up is converted into frictional force by pulling force, and as the increase of lifting power, frictional force are also incrementally increased and led with reaching
The purpose drawn.
