Detailed description of the invention
Herein below will be arranged in pairs or groups accompanying drawing, by particular specific embodiment, technology contents of the present utility model is described, those skilled in the art can be understood other advantages of the present utility model and effect easily by content disclosed in this specification. This utility model also can pass through other different specific embodiments and be implemented or apply. Every details in this specification may be based on different viewpoints and application, without departing substantially from, under spirit of the present utility model, carrying out various modification and change. Especially, in accompanying drawing, the proportionate relationship of each element and relative position only have exemplary use, not represent the actual state that this utility model is implemented.
Referring to Fig. 1 to Fig. 3, Fig. 1 in order to the component decomposition map of fixing device of the present utility model to be described, Fig. 2 is in order to illustrate the component installation diagram of fixing device of the present utility model, and Fig. 3 illustrates that fixing device of the present utility model is applied to fix a fractured bone.
As depicted in figs. 1 and 2, fixing device of the present utility model includes hone lamella 2 and the sleeve 3 being socketed on hone lamella 2, wherein, hone lamella 2 includes joint hole 21, the canned paragraph 23 that be connected at an angle with joining section 22 and the multiple perforation 24 being formed on canned paragraph 23 that a joining section 22, is formed in joining section 22, wherein, sleeve 3 includes a body 32, from the junction surface 31 that body 32 end extends to form and a through hole 33 being formed in body 32.
Engaging hole 21 removably to install with for sleeve 3, angle folded between joining section 22 and canned paragraph 23 makes joining section 22 compared to the inclined shape of canned paragraph 23, and the perforation 24 on canned paragraph 23 supplies screw 42 through to be fixed in this fractured bone by hone lamella 2.
The junction surface 31 of sleeve 3 extends from the end of body 32 and radius convergent is with tapered, that is, roughly, the joint hole 21 being smaller in size than hone lamella 2 at junction surface 31 is to insert in joint hole 21, and the size of body 32 is substantially the same with the size engaging hole 21, during to insert joint hole 21 in junction surface 31, body 32 is made to abut with the joining section 22 of hone lamella 2. Additionally, the through hole 33 of sleeve 3 is identical with the bearing of trend engaging hole 21 of the joining section 22 of hone lamella 2, and tapered junction surface 31 can give urgent cooperation when the end of sleeve 3 enters the joint hole 21 at junction surface 22. Also can enter smoothly when the end of nail 41 is inserted through hole 33 simultaneously and engage hole 21, it is provided that activeness fully.
Sleeve 3 of the present utility model engages fixing with the joining section 22 of hone lamella 2 in the way of being mutually socketed and applying external force (such as: knock), and the combination of sleeve 3 and hone lamella 2 is as shown in Figure 2. Therefore, assessed and select sleeve 3 length used needed for patient by doctor, in preoperative by sleeve 3 with hone lamella 2 to knock in mode secure bond, can according to adjusting required length needed for patient, sleeve 3 of the present utility model engages the entire length of the joining section 22 of hone lamella 2 between 20 to 40mm, thus increases the motility on using.
As it is shown on figure 3, fixing device of the present utility model is generally used in the femur of fracture, its femur bulb 11 separates from neck of femur 12 fracture. Doctor assesses and selects sleeve 3 length needed for patient, the joining section 22 of fixed engagement is selected again sleeve 3 and hone lamella 2, then, nail 41 is utilized to be placed through between femur bulb 11 and neck of femur 12, and make nail 41 rear end be placed through in the through hole 33 of sleeve 3, and the canned paragraph 23 of hone lamella 2 laterally abuts on femur backbone 13, recycling screw 42 is respectively through the perforation 24 on canned paragraph 23 and then enters femur backbone 13, thus completes the installing of slidingtype hip joint screw.
In sum, the fixing device of fixing fractured bone of the present utility model mainly includes hone lamella and is releasably coupled the sleeve in hone lamella, doctor can select suitable sleeve to be arranged on hone lamella according to patient demand, solves the joining section only having hone lamella in prior art and plants and the fixing puzzlement that cannot adjust of the size of joining section for nail. Therefore, fixing device of the present utility model have employed modularized design, can comply with different demand and select the length of different sleeve, so that sleeve engages the entire length of the joining section of hone lamella between 20 to 40mm, substantially increase the motility in use.
