Description
Technical Field
The utility model belongs to the technical field of medical instrument technique and specifically relates to an operating instrument who is used for shin bone intramedullary nail installation among the orthopedic operation.
Background
In order to reduce the pain of patients, shorten the operation time and meet the requirement of humanized operation, in the existing orthopedic operation, various operation instruments are usually used for achieving the purposes. However, the handle of the operation instrument for installing the tibial intramedullary nail is not comfortable and stable when being held, the far-end aiming frame is inconvenient to install, a positioning clamp for fixing the position of the far-end aiming frame is easy to separate and drop, the aiming device is required to be replaced for aiming at the locking hole of the near-end angle, aiming at the far-end locking hole is relatively far because the far-end aiming rod is a straight rod, the distance between the far-end aiming rod and the straight rod is relatively short, the aiming accuracy is relatively poor, meanwhile, a relatively large operation space is required, the adjustment and pre-installation of the instrument occupy a long time in the actual operation, the operation time is correspondingly prolonged, and.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a tibial intramedullary nail operation instrument which has good hand feeling, stable control and convenient and quick installation and adjustment.
The utility model discloses realize that the technical scheme that its purpose adopted is: the utility model provides a shin bone intramedullary nail operation apparatus, includes handle, distal end sighting rod, distal end aiming arm, locating lever, the handle upper end is through transition piece rigid coupling distal end sighting rod, the distal end aiming arm passes through the locating lever and installs the distal end at distal end sighting rod, the handle lower extreme is equipped with angle conversion mechanism to through its butt joint intramedullary nail, the locator card that can control the activity is cup jointed to the distal end of distal end sighting rod, the locating lever passes through its longitudinal displacement of locator card restriction and fixes distal end aiming arm.
The utility model discloses a further improvement lies in: in order to reduce the aiming distance of the far end and ensure that the aiming is more accurate, the far end aiming rod is
The distal end of the structure is bent medially.
In order to limit the longitudinal movement of the positioning rod and fix the far-end aiming frame, the positioning clamp is provided with a clamping jaw, the positioning rod is provided with a clamping groove matched with the clamping jaw, and the positioning clamp and the clamping jaw are clamped and limited.
In order to make the handle comfortable and stable to hold during operation, the inner side of the handle is provided with a protruding part which is convenient for holding.
When the utility model is operated, the handle is stably held, the comfort is good,and the angle of the nail fixing hole of the intramedullary nail can be adjusted by the angle changing mechanism, thereby
The distal aiming rod of the structure not only effectively shortens the distal aiming distance, but also reduces the operation space; the phenomenon of dropping can not appear to the design of locator card, and the quick adjustment and the fixed of the distal end aiming frame of being convenient for more effectively reduce the operation time.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic perspective view of the present invention.
In the figure, 1 is a handle; 11 is a protruding part; 2 is a transition block; 3 is a far-end sighting rod; 4 is a lock nut; 5 is a far-end aiming frame; 6 is a positioning rod; 7 is a positioning card; 71 is a claw; 72 is a card slot; 8 is a guide sleeve; 9 is an angle changing mechanism; 10 refers to intramedullary nail.
