Abstract

The utility model relates to a multifunctional straightening device for traction, composed of a bow, a width regulating mechanism, a steel-pin fixing mechanism and a traction-rope hanging mechanism. In the course of traction, without other hole-drilling devices, steel hammers, steel nails, etc., with simpler operation, steel-pins are screwed into the bone by a spanner. The device also has functions replacing those of various traction devices. The device can be used for the treatment of cervical-vertebra fracture, cervical-vertebra dislocation, pelvis fracture, sacrum-joint dislocation, intra-fracture of the neck of femur, simple tuberosity-fracture, femur fracture, tibiofibula fracture, etc., and has better clinical-trial effect; the utility model is a simple, safe, reliable and effective traction device for the orthopedics.

Description

Orthopaedics multifunction tractor

This utility model relates to the shaping apparatus in a kind of skeleton or joint, particularly a kind of multi-functional orthopedic instruments of drawing or resetting of being used to.

Traction technique is used comparatively extensive at orthopaedics, be usually used in fracturing reset and continue fixing, promote healing, have the muscle spasm of overcoming simultaneously, improve blood circulation, reduce patient's pain, be convenient to characteristics such as nursing.In traction, normally draw different positions and adopt different traction devices.Such as fracture of cervical vertebra or dislocation of cervical vertebra is to adopt skull traction bow (crutc-hfield) or various types of ice tongs.With special drilling equipment, in the boring of skull both sides, then drawing (see figure 1) in the increment patchhole of skull traction bow.(seeing Fig. 2,3) such as stainless pin (Kirschner), stainless steel nail (steinmann), skeletal traction bow and steel columns are then adopted in fracture, dislocation for lower limb.Above traction device all exists certain shortcoming: two arms of skull traction bow are shorter, the special tectonic of hook in addition makes this apparatus can not be firmly excessive in the utilization process, otherwise will cause the sclerotin fracture of hole portion, and when operation again need be with special drilling equipment, operation is complexity comparatively.In traction therapeutic process, apparatus often comes off easily, influences therapeutic effect.For the used traction bow of extremity, when being operation, its major defect needs steel nail or draw point to be squeezed in the limbs with steel hammer, and this can cause the local pain of fracture site because of vibrations.In addition, also be difficult between steel nail or draw point and the traction bow fixing, often cause traction bow displacement and compressing skin.

Shortcoming at above-mentioned traction device, this utility model provides a kind of improved multi-functional orthopedic traction apparatus, and its purpose is: simplify the operation course, avoid knocking drawbacks such as vibrations and apparatus easily come off, improve the traction therapeutic effect, and reach a device and have multiple functions.

The purpose of this utility model realizes by following approach: its device is made up of bow body, width adjustment mechanism, steel pin fixed mechanism and hauling rope hitch.The essentially identical bow body of two shapes connects by pivot pin, and formation can be around the tong-like structure of pivot pin rotation.Width adjustment mechanism is by regulating bolt, interior adjusting nut, regulate nut block outward, and will regulate bolt one end and bend body and be connected by pivot pin.The steel pin fixed mechanism is made up of steel pin, steel pin frame and rotary spanner, and steel pin is rotatably connected with the steel pin frame by screw thread, and becomes basic vertical configuration with the bow body in the bow plane that body constituted.The hauling rope hitch is U-shaped hauling rope hook, and the one end fuses with the bow body.

This utility model does not need other drilling equipment and steel hammer, draw point, steel nail in traction therapeutic process.Its operation is fairly simple, only needs by spanner getting final product in the steel pin screw-in bone.The utlity model has the function that substitutes multiple traction device.Can be used to treat in fracture of cervical vertebra, dislocation of cervical vertebra, fracture of pelvis, sacro-iliac joints dislocation, the neck of femur capsule and the simple fracture of tuberosity, Fracture of femur, fracture of tibia and fibula etc., good through clinical trial result, be a kind of simple, safe, reliable and effective orthopaedics traction device.

Sequence number is respectively in the accompanying drawing: 1-bends body; 2-bow body is pivot pin fixedly; 3-regulates the bolting pivot pin; 4-hauling rope hangers; Regulate nut in the 5-; 6-regulates nut outward; 7-regulates bolt; The 8-breach; The 9-block; The short steel pin of 10-; 11-steel pin frame; The 12-rotary spanner; 13-rotary spanner endoporus; 14-steel pin afterbody; The long steel pin of 15-; 16-steel pin head; 17-traction hook opening end.

The utility model will be further described below in conjunction with drawings and Examples.

Pass through fixedly pivot pin 2 connections of bow body with reference to accompanying drawing 4, the two essentially identical bow bodies 1 that are column type, and formation can be around the tong-like structure of pivot pin rotation.Width adjustment mechanism is regulated nut 6 outward by regulating bolt 7, and interior adjusting nut 5 is formed.An end of regulating bolt 7 is connected with bow body 1 by regulating bolting pivot pin 3.On bow body 1, be equipped with breach 8.When regulating this device width, regulating bolt 7 is that appropriate exercise is made in the center of circle in breach 8 with fixing pivot pin 3, inside and outside adjusting

nut

6,7 is tightened towards bending body 1 direction after adjusting to required width.

The steel pin fixed mechanism is made up of long steel pin 15 or short steel pin 10, steel pin frame 11 and rotary spanner 12.The middle part of steel pin is equipped with screw thread and screws in the steel pin frame 11.Steel pin in bow body 1 formed plane and with 1 one-tenth basic vertical configuration of bow body of link.The afterbody 14 of long and

short steel pin

15,10 is set to prismatic, and is at least triangular prism shaped.The endoporus 13 and the prismatic of steel pin afterbody 14 of rotary spanner match.The head 16 of long and

short steel pin

15,10 is the drill bit shape, also has protruding block 16 in head end, and for adapting to the demand of traction different parts, its head 16 can also be declined block 16(referring to Fig. 6).

The hauling rope hitch is a U-shaped traction hook 4, and one end and bow body 1 fuse, and for the ease of the suspension of hauling rope, the opening end 17 of U-shaped traction hook 4 upwards warps, its central axis and the Plane intersects (referring to Fig. 5) of bending body 1 place.
