Description
Technical field
This utility model relates to technical field of medical.
Background technology
At present, in the Patella fracture surgical operation, the kind of the internal fixation utensil of use is a lot, with regard to clinical therapeutic efficacy, the poly-kneecap pawl of Ti-Ni marmem is better than other fixing means, and outstanding performance is to possess lasting plus-pressure, is convenient to advantages such as knochenbruch tissue growth, incrustation, reparation.But traditional patella fracture fixator is the bad assurance of control of clamping deflection at low temperatures, and instrument does not match; Take out trouble when second operation, jaw is bad to be entered; Apparatus shape after being forced to strut has part to recover, the operation that causes the doctor to repeat to strut, and repeated multiple times has prolonged operating time, has increased patient's misery; Distal tip colludes that angle is set is big, occurs postoperative slippage and relaxation easily.
The utility model content
This utility model purpose provides a kind of orthopaedics internal fixation patella fracture fixator simple in structure, esy to use, safe and reliable.
This utility model comprises poly-kneecap main body, and an end of poly-kneecap main body connects three poly-holding claws, and the other end connects two locating detents; The free end of locating detent and poly-holding claw is respectively equipped with the point that points to poly-kneecap main body and colludes.
The appearance and modeling of this utility model integral body is human body and bend embraces a shape, meets Human Patella physiological mechanics structure, in the end of locating detent and poly-holding claw point is set and colludes, make the far-end claw to clasp power more stable.This utility model has been realized purpose simple in structure, esy to use, safe and reliable.
The angle that this utility model locating detent point colludes between most advanced and sophisticated place tangent plane and the locating detent free end place tangent plane is 80 °～100 °, and the angle that poly-holding claw point colludes between most advanced and sophisticated place tangent plane and the poly-holding claw free end place tangent plane is 110 °～135 °.It is the fixing anchor point of patella that the point of locating detent colludes, and it is the fixing impetus of patella that the point of poly-holding claw colludes.Poly-kneecap pawl sagittal shaped wire is the computer fitting curve, and non-circular arc transition curve more meets the physiology curved surface of Human Patella, and fixed effect can satisfy biomechanical property better.The point of locating detent colluded be designed to 80 °～100 °, purpose is to be convenient to accurately squeeze into operation behind the location; It is close that the point of poly-holding claw is colluded the physiological curve that is designed to 110 °～135 ° and patella, and it is reliable to keep postoperative to fix, and avoids occurring slippage and lax phenomenon.
Be respectively equipped with the sled salient point near free-ended both sides on each poly-holding claw of this utility model, a sled salient point that gathers both sides on the holding claw in the middle of being positioned at is towards two adjacent poly-holding claws, be positioned at a side on the poly-holding claw of both sides rise a sled salient point towards the centre poly-holding claw, opposite side rise the sled salient point dorsad in the middle of poly-holding claw; Be respectively equipped with the sled salient point near free-ended both sides on each locating detent, what be positioned at a side on the locating detent plays the locating detent of sled salient point towards another, is positioned on this locating detent rising of opposite side and prizes salient point another locating detent dorsad.Purpose is to be convenient to the V shape skid plate to insert and strut distortion, can not produce secondary to osseous tissue and destroy, and for the second operation taking-up provides great convenience, makes the simple more, reliable, quick and effective of operative process change, has alleviated patient's misery.
Description of drawings
Fig. 1 is that a kind of structure of the present utility model is launched sketch map.
Fig. 2 is the structural representation of this utility model user mode.
The specific embodiment
As shown in the figure, the upper end of poly-kneecap main body 1 connects three poly-holding claws 2, and the lower end connects two locating detents 3; The free end of poly-holding claw 2 and locating detent 3 is respectively equipped with the point that points to poly-kneecap main body 1 and colludes 5,6.
The angle that the locating detent point colludes between 6 most advanced and sophisticated place tangent planes and the locating detent 3 free end place tangent planes is 80 °～100 °, and the angle that poly-holding claw point colludes between 5 most advanced and sophisticated place tangent planes and the poly-holding claw 2 free end place tangent planes is 110 °～135 °.
Be provided with sled salient point 4 near free-ended both sides on each poly-holding claw 2, poly-holding claw 2-2 goes up rising of both sides and prizes salient point 4 towards two adjacent poly-holding claw 2-1 in the middle of being positioned at, a sled salient point 4 that is positioned at the last side of poly-holding claw 2-1 of both sides gathers holding claw 2-2 towards the centre, the middle dorsad poly-holding claw 2-2 of salient point 4 is prized in rising of opposite side; Be provided with sled salient point 4 near free-ended both sides on each locating detent 3, what be positioned at a last side of locating detent 3-1 plays the locating detent 3-2 of sled salient point 4 towards another, and what be positioned at that this locating detent 3-1 goes up opposite side prizes salient point 4 another locating detent 3-2 dorsad.
