Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1, the peg locking device for the gyroscope navigation intramedullary nail of the present invention comprises a handle 1, wherein the upper end of the handle 1 extends along the horizontal direction to form a first connecting portion, the lower end of the handle 1 is connected with a second connecting portion 2, the second connecting portion 2 is arranged along the horizontal direction, the second connecting portion 2 and the first connecting portion are arranged along the same direction, the second connecting portion 2 is used for connecting the proximal end of the intramedullary nail 9, the first connecting portion is provided with a connecting hole, one end of the positioning rod 3 close to the handle 1 is provided with an adjusting hole 4, the positioning rod 3 and the handle 1 can be fixedly connected by the matching of the adjusting hole 4, the connecting hole on the first connecting portion, the bolt 5 and the nut, so that the positioning rod 3 is also arranged along the horizontal direction, and the position of the positioning rod 3 relative to the handle 1 can be adjusted by the adjusting hole 4, when the position of the positioning rod 3 relative to the handle 1 needs to be adjusted, the bolt 5 is loosened, the corresponding part of the adjusting hole 4 is aligned to the connecting hole, and then the adjusting hole 4 and the connecting hole are locked through the matching of the bolt 5 and the nut.
Keep away from on the locating lever 3 that the one end of handle 1 is equidistant to be equipped with a plurality of guiding holes 7, aim probe 8 with the lockpin hole 10 cooperation of guiding hole 7 and intramedullary nail is used be equipped with gyroscope 6 on the locating lever 3 between regulation hole 4 and the guiding hole 7, can show angle numerical value and distance numerical value on the gyroscope 6, angle numerical value refers to the angle between locating lever 3 and the handle 1, distance numerical value refers to the distance between aiming probe 8 and the handle 1.
In a specific using process, before an operation, the near end of an intramedullary nail 9 is connected to the second connecting portion 2 of the handle 1, the aiming probe 8 is inserted into the corresponding guide hole 7 and the corresponding lock nail hole 10 so as to determine the position of the lock nail hole 10, then the positioning rod 3 is adjusted to a proper position according to the used intramedullary nail 9 so as to determine the angle between the positioning rod 3 and the handle 1 and the distance between the aiming probe 8 and the handle 1, after the angle and the distance are adjusted, the adjusting hole 4 and the connecting hole are locked through the matching of the bolt 5 and the nut, the angle value and the distance value displayed on the gyroscope 6 at the moment are recorded, and the accurate value of the lock nail is obtained.
Demolish after the utility model relates to a locking device squeezes intramedullary nail 9 into the bone in, when needs locking nail, on the repacking the utility model relates to a locking device adjusts locating lever 3 to relevant position for angle numerical value and the distance numerical value that show on gyroscope 6 are unanimous with numerical value before the art, later carry out intramedullary nail 9's distal end locking nail, thereby realized accurate locking nail process.
The utility model relates to a gyroscope navigation intramedullary nail locking device can make the operation locking nail more accurate, has shortened the time of operation greatly.
