Abstract

The invention discloses a kirschner wire puncture auxiliary positioning device for the orthopedics department, relates to the technical field of puncture positioning devices, and solves the problems that most of existing auxiliary positioning devices are not integrated with wiping and cleaning mechanisms for blood, blood on the skin around puncture positions needs to be frequently wiped manually,and the existing auxiliary positioning devices are tedious, strenuous and inconvenient to operate. The kirschner wire puncture auxiliary positioning device for the orthopedics department comprises a transmission case, the transmission case comprises a handle rod and a crank, the whole transmission case is of a rectangular structure, the L-shaped handle rod is supported and welded to the top end ofthe transmission case, and the crank is rotationally installed on the front side wall of the transmission case; and a T-shaped frame is integrally formed by jointly welding a transverse support mainbody plate and a vertical support shaft rod, wherein two sliding grooves are symmetrically formed in the transverse support main body plate in a penetrating mode. Sponge can rotate along with the T-shaped frame and a gear ring to sweep, wipe and clean blood flowing out of puncture positions, the trouble of frequently wiping the blood manually is omitted, the use and operation steps of the device are simplified, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of puncture positioning devices, in particular to a Kirschner wire puncture auxiliary positioning device for orthopedics. Background technique [0002] In orthopedic surgery, it is often necessary to drill a Kirschner wire through the skin and soft tissue into another preset bone for fixation. During the operation, due to the long length of the Kirschner wire, the drilling direction is slightly If there is a deviation, the final drilling position will have a large deviation and cannot reach the expected position. At present, in this case, the doctor will use a tool to move the Kirschner wire in the surgical incision to make the Kirschner wire The tip deflects to the preset direction, and then continues to drill; since the deviation is within a few millimeters in most cases, and the Kirschner wire has good elasticity, the effect of such a shift is not obvious, and it is often impossible to achieve One-time s...
