Abstract
The utility model relates to an anatomical type locking plate for the outer side of the near end of the thigh bone, which comprises a head part and a trunk part. The head part is slightly expanded, and the edge is round and obtuse and is bent towards the outer side; the head part is provided with a plurality of locking holes designed in an angulation way and small through holes for the temporary fixation of a Kirschner wire; and the anatomical type locking plate for the outer side of the near end of the thigh bone is matched with a minimal invasion tool for use, and the head part can be provided with a plurality of positioning holes of an aiming stand. The trunk part is in the shape of a long rod, and the far end of the trunk part is in a shuttle-shaped structure; the near end of the trunk part is bent towards the outer side, and the far end is bent towards the back; and the trunk part is provided with a plurality of locking holes and pressurizing holes. The anatomical type locking plate for the outer side of the near end of the thigh bone has the following positive effects that the probability of no joint with the thigh bone is reduced by the design of single bending of the dry dirt end on the basis of the design of the anatomical structure of the thigh bone of a Chinese person; the pulling-out resistance of screws is increased by the locking holes designed in the angulation way at the head part; meanwhile, the occurrence of necking down after operation is reduced; the condition that several other screws successfully penetrate into the neck of the thigh bone and the head of the thigh bone can be ensured only by the positioning of a locking screw in the operation, so that the process of the operation is simplified; and the anatomical type locking plate for the outer side of the near end of the thigh bone not only can be used for carrying out open type operation but also can be used for carrying out minimally invasive operation.
Description
[technical field]
This utility model relates to the surgical medical equipment technical field, specifically, is a kind of near end of thighbone outside anatomical form lockplate.
[background technology]
Use more traditional near end of thighbone outside locking steel plate clinically and have the design of femur anterior arch form preformed type, and its roomy metaphysis steel plate design can contain whole greater trochanter lateral wall, and match; On the other hand, the many screws of near-end are inserted the hole can select angle of pedicle screw flexibly, is fixed in neck of femur through greater trochanter, and has reached angle stability with the lock screw cooperation, strengthens anti-rotation performance, avoids postoperative to reset and loses.Yet this design of whole greater trochanter lateral wall is contained in this roomy being enough to of traditional near end of thighbone outside locking steel plate, in art, occurs and the not docile phenomenon of tuberosity part greater trochanter; Near-end becomes the lock screw at angle to be prone to the phenomenon that the position trains off simultaneously, and can't throw neck of femur into.
[utility model content]
The purpose of this utility model is to overcome the deficiency of prior art; A kind of near end of thighbone outside anatomical form lockplate is provided; Reduce art light plate and the not docile phenomenon of tuberosity part; Combine state's human femur anatomic form to design to near-end locking axially bored line direction simultaneously, avoid screw can't throw the phenomenon of neck of femur into, be perform the operation more smooth, easy.
The purpose of this utility model realizes through following technical scheme:
A kind of near end of thighbone outside anatomical form lockplate is characterized in that, is made up of head and cadre; Described head expands, and the edge circle is blunt; The inboard is provided with cambered surface; The outside is provided with cambered surface; Described cadre is elongated rod shape, and the edge circle is blunt; The inboard is provided with cambered surface; The outside is provided with cambered surface; Cadre's far-end is the fusiformis structure; Described cadre's near-end is crooked toward the outer side, is connected with head.
Wherein, head expands slightly, and the edge circle is blunt; The inboard is provided with cambered surface, in order to the applying femur; The outside is provided with cambered surface, reduces incisura.
Described head is crooked, docile in femoral trochanteric toward the outer side.
Described head is provided with some lock holes; According to its axis angle of femoral neck form design; The one-tenth angle design of lock hole, the resistance to plucking that has increased screw is exerted oneself, and the design of special one-tenth angle; Can make to guarantee through the positioning instant of one piece of lock screw in the art that other several pieces of screws can squeeze into neck of femur and femoral head smoothly, simplify operation process.
Described head is provided with some small through hole, can supply Kirschner wire temporary fixed.
Described head can be provided with some diopter locating holes, uses in order to matching with micro-traumatic instrument diopter.
Described cadre is elongated rod shape, and the edge circle is blunt; The inboard is provided with cambered surface; The outside is provided with cambered surface; Cadre's far-end is the fusiformis structure.
Described cadre's near-end is crooked toward the outer side, is connected with head, and is docile in femoral trochanteric.
Described cadre's far-end is towards rear curved, and it is arciform forward that whole cadre is.
Described cadre is provided with some lock holes and pressurization hole, to the fracture end pressurization that resets.
Compared with prior art, the good effect of this utility model is:
(1) this utility model is done the single curved design of dirt end and has been reduced the probability of not fitting with femur based on the human femur anatomical structure design of typical state;
(2) staggered designs of this utility model through many pieces of screws of the neck of femur resistance to plucking that increased screw is exerted oneself, and has reduced the generation of postoperative necking down simultaneously;
(3) the angled locking hole of the head particular design of this utility model can guarantee need only can squeeze into neck of femur and femoral head smoothly through other several pieces of screws of location of one piece of lock screw in the art, has simplified operation process;
(4) but both open surgery of this utility model also can be carried out Minimally Invasive Surgery through the diopter system of Wicresoft of special use.
