Abstract
The utility model relates to medical instruments for traction treatment of lower limb fracture patients in hospitals, in particular to an automatic lower limb fracture retractor. The automatic lower limb fracture retractor comprises a traction rope and a pulley installed on a sickbed, wherein one end of the traction rope is connected with a support arranged at the fracture; the other end of the traction rope winds around the pulley and then is connected with a worm; the worm is meshed with a worm wheel driven by a motor. The support is dragged through the transmission mode of the worm and the worm wheel, an original manual method is replaced, and convenience is brought to work of hospitals; a control center, a force meter and the motor form an automatic control system, once the traction changes, the control system will automatically adjust the traction, the purpose of accurately controlling the traction is achieved, and the fracture patients can recover as soon as possible.
Description
Technical field
This utility model relates to the medical apparatus and instruments that hospital's patients with lower limbs fracture carries out traction therapeutic, is leg fracture tractor specifically.
Background technology
At present, the traction apparatus that each hospital resets for patients with lower limbs fracture mainly comprises pull rope and pulley, one end of pull rope connects the support of fracture, and the other end is walked around pulley rear-mounted counterweight, and controls pull strength by the quantity of artificial increase counterweight or the weight of replacing counterweight.Because patient lies in sick bed, can move, pull strength is changed, once pull strength changes, just should regulate the weight of the counterweight of counterweight.But for existing Artificial Control method, frequently change very inconvenience of counterweight, increase burden not only to hospital nurse personnel's work, and the reset of fracture patient is made troubles.
Utility model content
For above-mentioned technical problem, this utility model provides a kind of traction fracture of the lower limb automatic tractor easily.
This utility model solves the problems of the technologies described above adopted technical scheme: fracture of the lower limb automatic tractor, comprise pull rope and pulley is on one's sick bed installed, described pull rope one end is connected with the support that is arranged on fracture, the other end is connected with a worm screw after being wound around pulley, and worm screw and is meshed by motor-driven worm gear.
As preferably, described in worm screw and pull rope, between the other end, be provided with ergometer, the dynamometry signal of this ergometer is passed to a control centre, and control centre is according to the keying of motor described in dynamometry signal controlling.
As preferably, described pulley is arranged on the bed bar of described sick bed by pulley yoke.
As preferably, described pulley yoke comprises that a side relative with this draw-in groove is provided with a pair of clamp holder according to a draw-in groove for bed bar cross sectional shape molding, and described pulley is installed this between clamp holder by rotating shaft.
As can be known from the above technical solutions, this utility model draws support by the kind of drive of worm and gear, has replaced original manual method, to hospital work, has brought facility; And form automatic control system by control centre, ergometer, motor, once pull strength changes, control system can regulate pull strength automatically, realizes the object of accurately controlling pull strength, to guarantee fracture patient rehabilitation as early as possible.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with Fig. 1, introduce in detail fracture of the lower limb automatic tractor of the present utility model, it comprises pull rope 1 and is arranged on the pulley 3 on sick bed 2, described pull rope one end is connected with the support 4 that is arranged on fracture, the other end is connected with a worm screw 5 after being wound around pulley, worm screw and the worm gear being driven by motor 67 engagements.After starter motor, motor drives worm gear rotation, and worm gear drives worm screw to move, and worm screw drives pull rope to move, thereby controls pull strength.
In order to reach the object of automatic traction, this utility model is being provided with ergometer 8 between the other end described in worm screw and pull rope, and the dynamometry signal of this ergometer is passed to a control centre 9, and control centre is according to the keying of motor described in dynamometry signal controlling; Wherein, control centre is prior art, and it can be controlled motor according to the value of thrust of setting and drive worm gear motion, realizes the object of accurately controlling pull strength.
In this utility model, described pulley 3 is arranged on the bed bar 21 of described sick bed by pulley yoke 31; Described pulley yoke comprises that draw-in groove can be made by plastic material according to a draw-in groove 32 for bed bar cross sectional shape molding, and it can directly snap in a bar, without utilizing aid, remove and install very simple, further for hospital work offers convenience; In a side relative with this draw-in groove, be provided with a pair of clamp holder 33, described pulley is installed this between clamp holder, to guarantee the normal operation of pulley by rotating shaft 34.
Above-mentioned embodiment is only for illustration of the utility model, and be not to restriction of the present utility model, the those of ordinary skill in relevant technologies field, in the situation that not departing from this utility model spirit and scope, can also make various variations and modification, therefore all technical schemes that are equal to also should belong to category of the present utility model.
