Abstract
The utility model discloses an orthopedic traction device, which is characterized by comprising a fixed traction block and a moving traction block, wherein the fixed traction block and the moving traction block are connected through a parallel sliding rod, and are fixed on limbs of patients at the same time, and a force application device is arranged in the fixed traction block, and transports pressure to the moving traction block through a force application rod which is arranged between the fixed traction block and the moving traction block, thereby enabling the moving traction block to move opposite to the fixed traction block, leading the limbs to be pulled, and reading traction size through a display window on the side surface by arranging an electronic sensor in the moving traction block.
Description
Technical field
This utility model 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, at patient's lower limb (lower limb), binds holder, connects a rope on holder, rope through a pulley after 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 of reason delay treatment.In clinical research, data show to draw the mutual relation of strength and traction effect accurately, 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 utility model is to provide a kind of quantitative assay and describes fracture site traction strength, improves clinical therapeutic efficacy, the bone distraction device brought convenience for clinical research.
For reaching above purpose, this utility model 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, be provided with a force application apparatus in the fixed traction piece, 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, be provided with an electronic inductor in mobile guiding piece, 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, by the simulated pressure signal processing, is that digital signal exports on the display window of mobile guiding piece side and intuitively reads.
Described fixed traction piece and be provided with the physiology concave surface above mobile guiding piece.
Compared with prior art, the utility model has the advantages that, 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.
