Description
Technical field
The utility model relates to the technical fields of medical instrument, more particularly to a kind of for the outer solid of fracture of distal radius
Determine device.
Background technique
Fracture of distal radius refers to fracture (the span distal aspect of the radius for betiding pronator quadratus nearside edge with distal part position
Fracture within 3cm).Distal radius is bone structure using section as the Radial of the distal radius of quadrangle and triangle generation shape
The region of state variation, cortical bone is relatively thin, bears the lesser cancellous bone of pressure in cortical bone.Radius inferior articular surface be thenad incline and
The joint that ruler inclines, after place hands on floor is injured, the stress for slapping back side and ruler oar side of radius inferior articular surface is simultaneously uneven, thus in oar
The size of bone distal end transmitting strength is uneven, and the side that stress compares concentration easily causes fracture.
Set by small splints from outside treatment fracture of distal radius is the important means of China's traditional medicine, plintlet treatment fracture master
If maintaining fracture correctly multiple by the efficacy of external bandage restraining force, the power of the flexible fastening of plintlet and pressure pad
Position, however traditional plintlet is unable to control fixed power when fixed when early rehabilitation, becomes since fracture site has displacement
Gesture loosens clamping plate further, and fixation is too loose to be easy to cause fracture dislocation and wrist joint function obstacle；Consolidate in later period rehabilitation
Ding get Tai is tight, is easy to cause damage and sympathetic reflex dystrophy of ischemic contracture, nerve and tendon etc. simultaneously
The generation for sending out disease, needs to carry out operative treatment again, causes unnecessary pain to patient.
Utility model content
The purpose of the utility model is to provide a kind of external fixers for fracture of distal radius, can be effectively controlled clamping
Fixed power, can make in early rehabilitation fracture of distal radius position obtain it is good reset, and when being avoided that later period rehabilitation
The bad complication as caused by fixed tension.
To solve the above-mentioned problems, the utility model provides a kind of external fixer for fracture of distal radius, including
For clamping fracture site clamping plate group, be provided at circumferentially spaced be used in clamping plate group periphery it is that clamping plate group and fracture site is fixed
More activity fixing belts and pressure-detecting device, the pressure-detecting device are arranged in the activity fixing belt；
The pressure-detecting device includes shell, and control element, pressure sensor and buzzing report are equipped in the shell
Alert device, the pressure sensor and the buzzer siren are electrically connected with the control element, and the pressure sensor is used for
Incude the pressure that the activity fixing belt applies the clamping plate group and pressure is converted to electric signal and feeds back to the control member
Part.
Further, the upper surface of the shell is equipped with display screen, and the display screen is electrically connected with the control element.
Further, the activity fixing belt include first band body, second band body and third band body, the first band body,
Second band body and third band body include free end and fixing end, the fixing end of the first band body, the described second consolidating with body
Fixed end and the third are fixedly connected with the fixing end of body by buckle, the free end of the first band body, second band
The free end of body and the third with the free end of body are equipped with adhesive layer and corresponding with adhesive layer by adhesive layer, described
Pressure-detecting device is arranged on the first band body.
Further, the clamping plate group include the palm clamping plate for being fixed on palmar side, the back splint for being fixed on dorsal side and
The front end of two pieces of side clamping plates being fixed between palm and the back of the hand, the palm clamping plate, back splint and side clamping plate is equipped with bending
Portion.
Further, the palm clamping plate, the back splint and the side clamping plate are equipped with liner layer.
Further, the liner layer is diablement fort.
Further, the palm clamping plate, back splint and side clamping plate are Chinese fir board.
Further, the shell is plastic casing.
A kind of external fixer for fracture of distal radius provided by the utility model, passes through the clamping fractures of clamping plate group
Position, clamping plate group are circumferentially arranged along fracture site, then have been provided at circumferentially spaced activity fixing belt in the periphery of clamping plate group, and activity is fixed
Band can be elastic with activity adjustment, guarantees that clamping plate group can fasten fracture site, pressure-detecting device is equipped in activity fixing belt,
Specifically, pressure sensor in pressure-detecting device can be with pressure (pressure that sensed activity fixing belt applies clamping plate group
It is equivalent to the pressure that clamping plate group applies fracture site), and pressure is converted to electric signal in time and feeds back to control element, it controls
Element is compared according to the pressure value of feedback and preset pressure value, and generally, pre-set pressure range works as activity in 600g~800g
When the pressure that fixing belt applies clamping plate group is less than 600g, it is clamping too loose and then cause fracture dislocation and wrist to will lead to clamping plate group
Joint function disturbance will lead to that clamping plate group is clamping tightly to be made very much when the pressure that activity fixing belt applies clamping plate group is greater than 800g
At complication such as ischemic contractures, so, when the pressure that pressure sensor detects that activity fixing belt applies clamping plate group is small
In 600g or be greater than 800g when, i.e., control buzzer siren issue alarm signal, prompt patient's adjustment activity fixing belt, this reality
In novel, the pressure value that clamping plate group is applied by the pressure-detecting device fixing belt of detection activity immediately, so that activity is fixed
The pressure that band applies clamping plate group is constantly in optimum range, both can guarantee that fracture of distal radius position makes fractures by clamping
Position obtains good reset, and is avoided that bad complication caused by the fixed tension of clamping plate group.
