Abstract
The utility model discloses a detachable gun-type fracture repository. The detachable gun-type fracture repository comprises a gun-type body, a steel wire guiding device and a pushing rod. The gun-type body comprises a sleeve, a handle and a trigger-type pressing plate. The pushing rod is arranged in the sleeve in a penetrating mode and slides forward along the sleeve by the effect of trigger-type pressing plate. The steel wire guiding device comprises a first clamping groove and a second clamping groove which are used for clamping a fracture position through cooperation. The handle and the trigger-type pressing plate are intersected and assembled together with a cross point as a rotary shaft. The detachable gun-type fracture repositor has following beneficial effects: based on the principle that a plane is determined by three points, accurate butt joint between the first clamping groove and the second clamping groove is ensured and dislocation of the first clamping groove and the second clamping groove are avoided; by means of the principle of pressurization by gradual pushing, fracture and fissure positions are repositioned with a balanced and accurate reset force, reliable reposition and little likelihood of loosening; when the detachable gun-type fracture repository is applied to an minimally invasive surgery, penetration of a steel wire can be effected without periostea-stripping operation because the front end of the pushing rod is provided with the steel wire guiding device; the likelihood of excessive damage to partial important vascular tissue of patients and complications of many kinds are lessened and avoided; and the detachable gun-type fracture repository is time-saving and labor-saving.
