CN2691551Y - Lateral moving mechanism of hanger frame type operation shifting cart - Google Patents

Abstract

The utility model relates to a lateral moving mechanism of a hanger frame type operation shifting cart. The utility model uses a worm wheel speed reducer to drive a driving hanging arm to rotate, and the driving hanging arm drives a driven hanging arm to rotate through a wire rope in a figure-eight shape. The rotation of the two hanging arms pushes a hanging rail to transversely move so that a hanger frame is driven to transversely move.

Description

The transverse moving mechanism of nose suspension type operation mover

Technical field

This utility model has related to that a kind of hospital uses, and belongs to technical field of medical instruments, the transverse moving mechanism of nose suspension type operation mover.

Background technology

Patient performs the operation, and not only labor intensity is big to the process that move in the ward from operating-table in the back, and will damage patient because of carelessness, more existing move car and all exist and need medical personnel to cause on the car with the manpower removing patient, from car, patient is moved on the sick bed again, though some mover, the car face has translation functions, but need manpower to assist patient is delivered on the car from operating-table, auxiliary patient is sent of reuse manpower causes on the bed, in its process, patient still exists position to move, and still has damage patient's probability.

Summary of the invention

In handling process,, position causes wound and in order to reduce patients after surgery in the damage of internal organs because of moving, alleviate medical workers, this utility model provides a kind of transverse moving mechanism of nose suspension type operation mover, patient does not need that manpower is auxiliary to be done position and move just and patient can be moved on the sick bed in ward from operating-table stably, avoid carrying to cause the probability of damage, also alleviated medical personnel's labor intensity simultaneously.

The technical scheme that its technical problem that solves this utility model adopts is: the gear elevating mechanism with the worm reducer driving that respectively has a cover to link mutually at the two ends of mover, the upper end of elevating mechanism is that axle sleeve a pair of arm with the cylindrical rack, the large shaft sleeve top of one of them arm is equipped with a worm reduction gear and is called initiatively arm, and another arm is the servo-actuated arm that is connected with the active arm by steel wire rope.Steel wire rope is 8 fonts the axle sleeve of two arms is linked up, the crank of transmission worm reducer is fixed on steel wire rope on the large shaft sleeve of arm initiatively along with the rotation of axle sleeve, one side of steel wire rope is toward pulling back, one side direction is put outward because two steel wire ropes are being fixed on the large shaft sleeve of idle rod in the back that intersects, therefore, servo-actuated arm large shaft sleeve under rope traction with the rightabout rotation of active arm macro-axis interplanting, the axle sleeve of two rightabouts rotation makes connected two arms rotate to equidirectional.Arm can also can turn right left, and by hanging axis pulley boatswain chair, thrust ball bearing is being connected two parallel hanger rails with pulley at the front end of two arms, when arm rotates, promotes hanger rail and does transverse movement.Big boatswain chair is passed through at two ends at hanger rail respectively, little boatswain chair and lever, the suspension bracket transverse slat, connecting by two barrels and two compressor arms and forming suspension bracket, when carrying patient from operating-table, be close together parallel of nose suspension type operation mover with operating-table, and car face and operating-table adjusted on the sustained height, (the selectable mode of car face lift in height mechanism is more here to be omitted) anti-inclination balanced controls are stablized car body (anti-inclination balanced controls separate case is applied for a patent here and is omitted), elevating mechanism is with the suspension bracket human body that raise, with transverse-moving mechanism suspension bracket is moved the people top of causing a disease simultaneously, at this moment operating elevating mechanism again descends suspension bracket, make the suspension bracket transverse slat at suspension bracket two ends, be pressed on the table top at operating-table two ends, at this moment continue to make suspension bracket to descend, at this moment big boatswain chair band little boatswain chair and is moved down, moving down by little axle of little boatswain chair moves up the other end of 4 levers, be fixed on 2 compressor arms on the lever and leave barrel and move up, make between compressor arm and the barrel and form certain distance.At this moment, the both sides of the sheet on the operating-table are started, the sheet both sides are pressed on the barrel, at this moment shaking hi/local crank moves upward suspension bracket, big boatswain chair and little boatswain chair drive lever by little axle when moving upward, with lever fulcrum shaft is that middle heart lever inboard moves upward, and the outside of lever is being with compressor arm to move downward, compressor arm is pressed into sheet in the barrel, the strength that suspension bracket moves upward at first becomes the pressure of compressor arm to barrel by lever, sheet being pressed in the barrel tightly, suspension bracket and sheet have just formed a platform that is equivalent to stretcher like this, at this moment continue to shake hi/local crank, and suspension bracket is lifted away from operating-table stably to patient, shake horizontal crank again, make suspension bracket laterally retract mover, shake hi/local crank again and make suspension bracket falling on mover slowly, at this moment recoverable anti-inclination mechanism, patient is delivered to by the sick bed in ward, patient is moved on the sick bed stably with opposite action.

The beneficial effects of the utility model are: postoperative patient is under situation about need not position moving, and a probability of sending the bed that causes a disease to reduce the damage patient from operating-table, and overall process stably need only people's operation, has alleviated medical personnel's labor intensity.
