Description

A kind of bone distraction device
Technical field
The present invention relates to a kind of traction apparatus for the experiment of orthopaedics tension test or Orthopedic Clinical treatment.
Background technology
Traction is the common technology of fractures, and it is the means of the reduction of the fracture, is also to maintain a kind of measure resetted.The principle of traction is to utilize pull strength and reverse drag power, acts on fracture site, has reached and has resetted and maintain the purpose resetted.Its Main Function is: (1) slow traction reaches the reduction of the fracture and maintains and resets, and corrects cripetura and angulation displacement, prevents malunion, for operation brings convenience, for some fracture, also can be used as a kind of ultimate treatment means; (2) prevent the excessively stimulation of displacement to soft tissue of fracture site, reduce secondary soft tissue injury and hemorrhage, alleviate patient's pain; (3) waiting for intra-operative, muscle around lax fracture site, reduce the adhesion of fracture site soft tissue, reduces the difficulty that resets, and reduces soft tissue in art and peel off with hemorrhage, shortens operating time.
Traction mainly comprises lower limb traction, upper limb traction, for the sliding traction of cervical vertebra etc.Fig. 1 is a kind of lower limb traction method at present commonly used, binds holder at patient's lower limb (lower limb), on holder, connects a rope, and rope passes after a pulley by a balancing weight to the lower limb tractive application of force.The method is simple to operate in clinical, technology is easy to grasp, be widely used, and the selection of trailing weight, it is key one ring that can reach the traction therapeutic effect, the selection of balancing weight weight depends on doctor's experience more, and lower limb traction is generally the 1/7-1/10 of body weight, and skin traction, upper limb traction and skull traction generally are no more than 5Kg.But the size of the traction strength of fracture site, much strength can be brought maximum benefit to the patient, there is no definite data and can't evaluate.According to experience, select, usually can be because of the friction of the stopping of the angle of pulley, support, pull rope and bed edge etc., it is unpredictable that can traction strength reach the expection level, and some patient may be because this kind reason delay treatment.In clinical research, need data accurately to show the mutual relation that draws strength and traction effect, and the dependency relation of traction strength and patient's healing time, yet there is no in the market this quantitative pulling equipment.
Summary of the invention
But the purpose of this invention is to provide a kind of quantitative assay and describe fracture site traction strength, improve clinical therapeutic efficacy, the bone distraction device brought convenience for clinical research.
For reaching above purpose, the present invention takes following technical scheme to be achieved:
A kind of bone distraction device, it is characterized in that, comprise a fixed traction piece and a mobile guiding piece, by parallel sliding bar, be connected between the two, this two guiding piece is fixed on patient's limbs simultaneously, wherein, in the fixed traction piece, be provided with a force application apparatus, this force application apparatus is passed to mobile guiding piece by the force application rod be arranged between fixed traction piece and mobile guiding piece by pressure, mobile guiding piece is runed counter in the fixed traction piece to be moved, cause limbs to be drawn, in mobile guiding piece, be provided with an electronic inductor, this traction size is read by the display window of side.
In such scheme, described force application apparatus comprises the micromachine, the rhizoid thick stick that are arranged on fixed traction piece inside, and an end of leading screw is fixed by bearing, and radially is connected with the micromachine rotating shaft by meshing gear pair; The other end is fixed by nut, and axially is connected with force application rod.
Described electronic inductor comprises that one is arranged on the pressure transducer of mobile guiding piece inside, it connects force application rod and puts in the terminal in mobile guiding piece, this sensor connects an integrated package by wire, is that digital signal exports on the display window of mobile guiding piece side and intuitively reads by the simulated pressure signal processing.
Described fixed traction piece and be provided with the physiology concave surface above mobile guiding piece.
Compared with prior art, advantage of the present invention is, but quantitative assay and description fracture site traction strength, and can study by pull strength data accurately the mutual relation of pull strength and traction effect, and the dependency relation of pull strength and patient's healing time, improved clinical therapeutic efficacy, and can be clinical research and bring convenience laboratory facilities.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of existing a kind of lower limb traction device.
Fig. 2 is the structural representation of apparatus of the present invention.
Fig. 3 is the concrete structure figure in fixing, the mobile guiding piece of Fig. 2 device.
In Fig. 1 to Fig. 3: 1, lower limb; 2, holder; 3, rope; 4, fixed pulley; 5, balancing weight; 6, fixed traction piece; 7, force application rod; 8, sliding bar; 9, mobile guiding piece; 10, physiology concave surface; 11, shift knob; 12, threading ring (ear); 13, display window; 14, micromachine; 15, leading screw; 16, nut; 17, pressure transducer; 18, integrated package.
The specific embodiment
Below in conjunction with accompanying drawing, technical solution of the present invention is described in further detail.
With reference to figure 2, a kind of bone distraction device, comprise the fixed traction piece 6 of a rectangle and the mobile guiding piece 9 of a rectangle, by a force application rod 7, be connected with two parallel sliding bars 8 between the two, during use, threading ring (ear) 12 with belt by the guiding piece left and right side is fixed on device on patient's limbs, wherein, in the fixed traction piece, be provided with force application apparatus, shift knob 11 by fixed traction piece side drives force application apparatus, force application apparatus is passed to mobile guiding piece by force application rod 7 by the pressure of its generation, mobile guiding piece is runed counter in the fixed traction piece to be moved, cause limbs to be drawn, display window 13 Gives of electronic inductor in mobile guiding piece side by wherein go out mobile guiding piece stressed size.Fixed traction piece and be provided with physiology concave surface 10 above mobile guiding piece, because people's extremity are irregular cycle, therefore, the physiology concave surface is more conducive to fix, and can not cause secondary damage to people's extremity.
With reference to figure 3, the force application apparatus of fixed traction piece 6 inside comprises a micromachine 14, a set of screw nut device.The startup of micromachine 14 can be controlled break-make by the shift knob 11 of fixed traction piece side, and an end of leading screw 15 is fixed by bearing, and radially is connected with the micromachine rotating shaft by meshing gear pair; The other end is fixing by nut 16, and axially is connected with force application rod 7.The terminal that force application rod 7 puts in mobile guiding piece is connected with a pressure transducer 17, this sensor connects an integrated package 18 by wire, is the display window 13(display screen that digital signal exports mobile guiding piece side to by the simulated pressure signal processing) on intuitively read.
Apparatus of the present invention can be used for the sliding traction of the lower limb traction of fractures or orthopaedics experimentation, upper limb traction, cervical vertebra etc.
