Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, some distortion and improvement can also be made.These all belong to protection scope of the present invention.
Referring to Fig. 1 and Fig. 2, is the STRUCTURE DECOMPOSITION schematic diagram of a kind of bone connecting device provided by the invention.Described bone connecting device comprises one for the acetabular cup link 10 that is connected with acetabular cup (not shown) and a pubis link 11 be arranged on this acetabular cup link 10.The whole metal material that can use of described bone connecting device is made.
Described acetabular cup link 10 comprises an adjustment rack 101, also comprises the first sliding shoe 102, the second sliding shoe 103 that are arranged in this adjustment rack 101.Described first sliding shoe 102, the second sliding shoe 103 are connected with acetabular cup, for when adjusting this first sliding shoe 102, making acetabular cup follow the first sliding shoe 102 and sliding, and then adjusting the relative position between this bone connecting device and acetabular cup.Described adjustment rack 101 is a hollow cuboid in the present embodiment, and is a terraced structure, and this step is equivalent to a guide rail, thus described first sliding shoe 102, the second sliding shoe 103 can be made along this slide.Therefore, the length of this step can be arranged according to the actual needs.One end of described adjustment rack 101 comprises a screw rod 104, and this screw rod 104 is for installing described pubis link 11.Described first sliding shoe 102, the second sliding shoe 103 are circular configuration, and are separately positioned on described adjustment rack 101 both sides.Described first sliding shoe 102 is arranged on the step of adjustment rack 101, and be limited to the edge of adjustment rack 101 framework, to limit the transverse movement of this first sliding shoe 102, but the length of adjustment rack 101 is greater than the diameter of the first sliding shoe 102, to make described first sliding shoe 102, the second sliding shoe 103 can adjust along the length direction of adjustment rack 101.Described first sliding shoe 102 and the second sliding shoe 103 are fixed by two bolts (not shown) that is connected, and by this bolt, this acetabular cup link 10 are connected with acetabular cup simultaneously.
Described pubis link 11 comprises one and is set in nut 112 in pubis bar 111 and one for locating the snap ring 113 of described nut 112 for 111, one, the pubis bar be connected with human body pubis.See also Fig. 3, described pubis bar 111 comprises a sleeve 114 and a tapered rod 115 be connected with this sleeve 114.Described sleeve 114 is in order to fixing sheathed described nut 112, and its one end offers a cannelure 116, and the other end is a stepped hole 117.Described cannelure 116 establishes described snap ring 113 for card.The diameter of the large diameter hole of described stepped hole 117 is suitable with the overall diameter of nut 112, and the diameter of the diameter of small diameter bore and the screw rod 104 of adjustment rack 101 is suitable, inserts in this sleeve 114 to make this screw rod 104.Described nut 112 inserts from one end of the large diameter hole of sleeve 114, and supports on described stepped hole 117, and the other end of this nut 112 is then fixed by snap ring 113.Described snap ring 113 is an elastic circlip, when being narrowed down to minimum diameter, can insert, and being fastened in cannelure 116, thus fix described nut 112 together with coordinating with stepped hole 117 from one end of the large diameter hole of sleeve 114.The length of described tapered rod 115 and diameter are determined according to the osteotomy length of human body pubis and pulp cavity size, are designed to assembly type series part, in order to insert pubis pulp cavity, to realize with the connection of pubis and to fix; Meanwhile, be designed with the equal spherical nest in interval along tapered rod 115 bar length direction, to grow into and fixing pubis.Between described tapered rod 115 and sleeve 114, be also provided with a platform 118, this platform 118 for coordinating with human body pubis end face, to reduce the pressure to human body pubis.
When assembling, first the first sliding shoe 102 of acetabular cup link 10, the second sliding shoe 103 are fixed with acetabular cup bolt.Then described pubis link 11 is assembled, namely first by sheathed for nut 112 enter pubis bar 111 sleeve 114 in, card is established into snap ring 113 again, is finally screwed on the screw rod 104 of acetabular cup link 10 by the nut 112 of this pubis link 11, thus assembles bone connecting device provided by the present invention.
Due to described first sliding shoe 102, for circular configuration, and the length of adjustment rack 101 is greater than the diameter of the first sliding shoe 102, namely acetabular cup can be able to be rotated on adjustment rack 101 with the first sliding shoe 102, also can slide along the length direction of adjustment rack 101, thus realize the adjustment on its three directions.Simultaneously, because acetabular cup link 10 is connected by nut 112 with pubis link 11, the degree of depth is screwed into by swivel nut 112 and nut 112, rotation adjustment and the translation that can realize acetabular cup link 10 and pubis link 11 adjust, thus can adjust according to practical situation in operation process as much as possible.In addition, this bone connecting device all uses the easy package assembly such as bolt, nut to make, thus can realize assembly type connection.
Above specific embodiments of the invention are described.It is to be appreciated that the present invention is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present invention.
