Abstract
The invention discloses a traction device of the orthopedics department. The traction device of the orthopedics department is characterized by comprising a fixed traction block and a movable traction block, the fixed traction block and the movable traction block are connected through parallel sliding rods, the two traction blocks are fixed on the limbs of a patient at the same time, a force application device is arranged in the fixed traction block and used for transmitting pressure to the movable traction block through a force application rod arranged between the fixed traction block and the movable traction block, and the movable traction block is made to move opposite to the fixed traction block, so that traction on the limbs is achieved; an electronic induction device is arranged in the movable traction block, and the traction degree can be read through a display window on the lateral side.
Description
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 a kind of measure that maintains reset.The principle of traction is to utilize pull strength and reverse drag power, acts on fracture site, has reached the object that resets and maintain reset.Its Main Function is: (1) slowly traction reaches the reduction of the fracture and maintains reset, 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, lax fracture site muscle around, reduces the adhesion of fracture site soft tissue, reduces reset difficulty, reduces soft tissue in art and peels 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 at present conventional lower limb traction method, binds holder at patient's lower limb (lower limb), connects a rope on holder, rope through 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 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 are generally no more than 5Kg.But the size of the traction strength of fracture site, much strength can be brought maximum benefit to patient, there is no definite data and cannot evaluate.Select according to experience, 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 expection level, and some patient may be because being 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, but there is no in the market this quantitative pulling equipment.
Summary of the invention
The object of this invention is to provide one can quantitative assay and describe fracture site traction strength, improves clinical therapeutic efficacy, the bone distraction device bringing convenience for clinical research.
For reaching above object, 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, be connected by parallel sliding bar between the two, this two guiding piece is fixed on patient's limbs simultaneously, wherein, in 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 being arranged between fixed traction piece and mobile guiding piece by pressure, mobile guiding piece is runed counter in 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 one end of leading screw is fixed by bearing, and is radially connected with micromachine rotating shaft by meshing gear pair; The other end is fixed by nut, and is axially 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 simulated pressure signal processing.
Described fixed traction piece and be provided with physiology concave surface above mobile guiding piece.
Compared with prior art, advantage of the present invention is, can quantitative assay draw strength with description fracture site, 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, improve clinical therapeutic efficacy, and can be clinical research and bring convenience laboratory facilities.
