Traditional traction technique, common ke shi needle and U type steel bow fix and draw, and traditional U type bow is very troublesome when installation and dismantlement, and is not convenient enough, also wastes time and energy during the doctor operation.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a split type bone traction bow to it is troublesome with dismantling to solve installation in the current traction bow, is unfavorable for doctor's operation.
In order to achieve the above object, the basic scheme of the present invention is as follows: the utility model provides a split type bone traction bow, includes first bow, second bow, wire rope handling ring and ke shi needle, and the one end of first bow and second bow all is equipped with the catch, all is equipped with the recess on the lateral wall of catch, and the other end of first bow and second bow is passed to ke shi needle, is equipped with a plurality of couples on the wire rope handling ring, a plurality of couples be used for with the recess block.
The utility model discloses a principle and beneficial effect: when bone is pulled by using a traction bow, the kirschner wire is inserted into the position to be pulled, the screw ends of the first bow and the second bow are respectively sleeved at the two ends of the kirschner wire, then the hook is hung at the groove of the locking ring, one end of the rope is tied on the stringing ring, the other end of the rope is tied on the bed, the rope is tensioned, the pulling force can tightly draw the locking ring of the first bow and the second bow, so that the traction effect is achieved, when the traction bow is required to be disassembled, the rope is unbundled, the hook can be taken out from the groove of the locking ring, the first bow and the second bow can be loosened, so that a doctor can take out the traction bow conveniently, the pain of the patient is relieved, meanwhile, the design of the independent hook is realized, and the installation of the doctor is more convenient when the traction bow is required to be used.
Further, the one end of first bow and second bow all is equipped with solid fixed ring, all is equipped with the screw of hand rotation on the solid fixed ring.
Has the advantages that: the Kirschner wire is inserted into a part needing to be pulled through the fixing ring, and the screw is rotated by hands, so that the screw abuts against the Kirschner wire under the rotation, and the Kirschner wire is fixed to prevent the Kirschner wire from sliding.
Further, the side of the two lock rings close to each other is flat.
Has the beneficial effects that: the flat shape of the locking ring close to can increase the contact area of the locking ring, so that the locking ring can be more firmly closed when being tensioned, and meanwhile, the area of the locking ring can be more when the hook is hung on the groove, so that the hook can be more firmly hung on the locking ring.
Furthermore, an elastic layer is arranged at the position close to the two lock rings.
Has the beneficial effects that: when the couple was pulled by the pulling force of rope, the catch will also be held to the couple, and the elastic layer near two catches can take place certain deformation under the effect of pulling force, and continuous extrusion inwards to this frictional force that can increase first bow and second bow and couple to certain protection.
Further, the hook is arc-shaped.
Has the advantages that: the arc-shaped hook can enable the first bow and the second bow to rotate and not fall off when being hung in the groove, and is suitable for the traction bow to be still fixed on a patient body when the patient moves or turns over, so that the traction tolerance of the patient is improved.
Further, a sponge layer is arranged in the groove.
Has the beneficial effects that: frictional force when the recess is hung to multiplicable couple on the one hand avoids the landing of couple, and on the other hand couple is hung in the recess for a long time, and certain wearing and tearing can inevitably cause, and the wearing and tearing of couple to the recess can be alleviated to a certain extent on the sponge layer.
Furthermore, elastic layers are arranged on the first bow and the second bow.
Has the advantages that: when pulling, need hang the couple in the recess the inside, through the pulling force of the rope of reeving ring, pulling first bow and second bow so that first bow and second bow draw close, the setting up of elastic layer can make first bow and second bow do benefit to more by the pulling force pulling of rope, from the operation of the medical staff of being convenient for.

Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the rope threading device comprises a rope threading ring 1, a locking ring 2, a second bow 3, a Kirschner wire 4, a screw 5, a groove 6, a hook 7 and a first bow 8.
The embodiment is basically as shown in the attached figures 1 and 2: the utility model provides a split type bone traction bow, including first bow 8, the second bow 3, wire rope handling ring 1 and ke shi needle 4, the one end of first bow 8 and second bow 3 all is equipped with catch 2, all be equipped with recess 6 on catch 2's the lateral wall, be equipped with the sponge layer in the recess 6, the other end of first bow 8 and second bow 3 all is equipped with solid fixed ring, gu all be equipped with the rotatory screw 5 of hand on the fixed ring, ke shi needle 4 passes the solid fixed ring of first bow 8 and second bow 3, and be connected with first bow 8 and second bow 3 through the rotatory screw 5 ke shi needle 4 of hand, be equipped with a plurality of couples 7 on the wire rope handling ring 1, preferably, two couples, couple 7 is the arc, a plurality of couples 7 are used for with recess 6 blocks.
The specific implementation process is as follows: when a traction bow is needed to be used for traction of bones, the Kirschner wire 4 penetrates through the fixing ring to be inserted into a part needing to be dragged, the first bow 8 and the second bow 3 are sleeved from two ends, the position of the Kirschner wire 4 is adjusted and then the positions of the first bow 8 and the second bow 3 are adjusted, then the Kirschner wire 4 rotates towards the Kirschner wire 4 by rotating the screw 5 with hands, so that the Kirschner wire 4 and the first bow 8 and the second bow 3 are locked, then the hook 7 is hung at the groove 6 of the locking ring 2, one end of the rope is tied on the stringing ring 1, the other end of the rope is tied on a bed, through tensioning the rope, the pulling force can enable the locking ring 2 of the first bow 8 and the second bow 3 to be tightly closed, the traction effect is achieved, when the traction bow needs to be detached, the rope is unbundled, the hook 7 can be taken out from the groove 6 of the locking ring 2, the first bow 8 and the second bow 3 can be loosened, therefore a doctor can take out the traction bow, the patient can be conveniently taken out, the pain of the patient is relieved, the independent hook 7 is designed, the doctor can be installed more conveniently when the traction bow 7 is needed to be used, the hook 7 can be installed and can be further, the hook can be hung in the first bow 6 and can be further, the second bow 8 can be rotatably hung on the patient can be still be moved, and can be fixed on the patient, and the patient can be still can be pulled, and the patient can be prevented from being pulled, and the patient.
