Abstract
The utility model discloses a patella guiding needle device, which comprises a transmission rod and a guiding needle. The transmission rod is provided with a front end and a rear end, and the rear end can be in coaxial transmission connection with a drill. The guiding needle is provided with a conical guiding end and a connecting end, and a through locking hole is disposed at the connecting end. A fracturing portion is a structure capable of being fractured and is fixedly connected to the tail of the front end of the transmission rod and the tail end of the connecting end of the guiding needle. The patella guiding needle device has the advantages that the patella guiding needle is provided with the locking hole, fixing suture can penetrate through the locking hole during fixing, the purposes of pressurizing a bone fracture end, preventing loosening or falling off of the fixing suture after operation, firm internal fixation, displacement of the bone fracture end and preventing falling off of the guiding needle can be realized, and fixation is firmer.
Description
Technical field
This utility model relates to a kind of patella guid needle device, particularly a kind of patella guid needle device that is used for the treatment of Patella fracture.
Background technology
At present clinically, the treatment Patella fracture mainly adopts following method: use Kirschner wire to pass place, Patella fracture end, fix with static line then.Adopt Kirschner wire, have following deficiency: during the treatment Patella fracture, the postoperative static line becomes flexible easily or comes off, and causes the fracture site displacement easily.
The utility model content
This utility model provides a kind of patella guid needle device, and it has overcome the existing deficiency of patella guid needle device in the background technology.
The technical scheme that is adopted that this utility model solves its technical problem is:
A kind of patella guid needle device, it comprises:
One drive link, it has the rearward end of a leading section and the coaxial rig that is in transmission connection of an energy;
One guid needle, the guiding end that it has one one-tenth taper is connected the end with one, and place, described connection end offers an interlocking hole of running through;
One broken part that can fracture, it is fixed in the leading section end of drive link and the end tip that is connected of guid needle.
Among one preferred embodiment: the rearward end cross section of described drive link is non-circular.
Among one preferred embodiment: the diameter of described broken part is less than the diameter of guid needle.
The technical program is compared with background technology, and it has following advantage:
1, the patella guid needle is provided with the interlocking hole, and described static line can pass the interlocking hole in the time of fixedly, then can reach the pressurization to fracture site, can prevent that the postoperative static line is loosening or come off, can realize strong internal fixation, can avoid fracture site to be shifted, can prevent that then guid needle from deviating from, fixing more firm;
2, affixed between drive link and the guid needle by the broken part that can fracture, broken in the art, then make things convenient in the art and operate, make things convenient for Minimally Invasive Surgery.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 has illustrated patella guid needle schematic representation of apparatus.
The specific embodiment
Please refer to Fig. 1, a kind of patella guid needle device, it comprises a drive link 100, a guid needle 200 and a broken part 300.
Described drive link 100, it has the rearward end 120 of a leading section 110 and the coaxial rig that is in transmission connection of an energy; Best, the rearward end cross section of described drive link 120 is non-circular, with the coaxial rig that is in transmission connection of energy.
Described guid needle 200, the guiding end 210 that it has one one-tenth taper is connected end 220 with one, and 220 places, described connection end offer the interlocking hole 221 of a circle that runs through.
Described broken part 300, what it was fixed in the terminal and guid needle 200 of the leading section 110 of drive link 110 is connected end 220 ends.The diameter of described broken part 300 is less than the diameter of guid needle 200, and its user can manually fracture.
Among the present embodiment, adopt the step of patella guid needle device clinical treatment followingly to describe:
1, user should read over " orthopaedics internal fixation " and other related datas that A0 organizational technology is recommended before using this product.And the skillfully operating process of this product.
2, patient body position: be generally dorsal position.
3, operative incision: vertical or horizontal otch, the otch size should be able to be put into implant, obtains surgical field of view clearly.
4, separate subcutaneous tissue and muscle, expose patella.
5, fracture end is resetted after with two patella guid needle devices, pass fracture site, behind the broken part of the guid needle that fractures, static line is passed the circular hole of guid needle, carry out colligation and fix, at last with the locker line that is locked.
The above, it only is this utility model preferred embodiment, so can not limit the scope that this utility model is implemented according to this, i.e. the equivalence of doing according to this utility model claim and description changes and modifies, and all should still belong in the scope that this utility model contains.
