Abstract
The utility model relates to a locking bone fracture plate system with an aiming device. The system comprises a bone fracture plate and an aiming device, wherein the shape of the bone fracture plate is consistent with the anatomical contour of femur or tibia; screw holes are distributed on the bone fracture plate; and the aiming device is provided with aiming through holes in one-to-one correspondence with the screw holes on the bone fracture plate respectively and is erected above the bone fracture plate through a plurality of guide sleeves passing through the aiming through holes. The guide sleeves are provided with central through holes for drilling on the femur or tibia and putting locking screws therein. Through the system, the bone fracture plate can be transcutaneously inserted and is fixed by the locking screws under the condition of not exposing a fracture region to reduce injury to soft tissues of the fracture part to the minimum extent; and a product has accurate plasticity and is not required to be bent in operation. The product is more stable compared with the similar products after being mounted and allows early activation of a patient.
Description
Technical field
This utility model relates to the skeleton field of fixation devices, specifically is a kind of locking bone fracture plate system that has sighting device.
Background technology
LISS (Less Invasive Stabilization System) is the advantage of an intramedullary nail with lock technology and new Wicresoft's internal fixation system that the blade plate technology combined and formed biology.Realize Wicresoft, obviously improved the clinical effectiveness of operative treatment DF, proximal tibia, Periprosthetic and osteoporotic fracture.
The locking bone fracture plate system that has sighting device, low operation is the technical barrier of this area to the damage of soft tissue.
The utility model content
This utility model technical problem to be solved provide a kind of simple in structure, clinical manipulation convenient, be suitable for reducing the locking bone fracture plate system that have sighting device of operation to soft tissue injury.
For solving the problems of the technologies described above, this utility model provides a kind of locking bone fracture plate system that has sighting device, comprising: blade plate that shape is consistent with the dissection profile of femur or tibia and sighting device; Be distributed with screw hole on the blade plate, have respectively on the sighting device with said blade plate on screw hole aim at through hole one to one; Sighting device is set up in the top of this blade plate through a plurality of fairleads that pass said aiming through hole.
Further, has the center through hole that is used on femur or tibia boring and sends into lock-screw on the said fairlead.
The utlity model has positive effect: the locking bone fracture plate system that has sighting device of (1) this utility model is applied to extremity fracture.This internal fixation can be under the situation that does not expose fractured area, and percutaneous inserts blade plate and also accomplishes the fixing of lock screw, and the soft tissue injury of bony site is eased down to minimum degree, and this product has accurate plasticity, in operation, need not to carry out bending.Product is more stable than like product after installation, allows patient to carry out activity in early days.(2) the locking bone fracture plate system of this utility model owing to use external screw hole sight, makes operation be reduced to minimum level to the damage of soft tissue.Self-drilling screw with angle fixation can provide more reliable fixation.LISS (LISS) is suitable for the fixing of DF and proximal comminuted fracture of tibia, especially fixing of sufferers of osteoporosis face and Periprosthetic fracture is more had its special advantages.The design of LISS blade plate, its shape are consistent with the dissection profile of bone, use the growth of fracture setting plate to replace long tubular fixed rod; Use snap close is tightly followed closely the fastening clamp that replaces widely used Schanz nail and projection in the exterior fixation bracket in the threaded powerful self-tapping screw of the head of blade plate.The lock screw nail also can obtain better hold in loose sclerotin, so LISS is more suitable for fixing in Periprosthetic fracture and osteoporotic fracture.Each lock screw nail of LISS blade plate can be screwed into by means of location, accurate screw hole axle center percutaneous; Therefore under the situation that does not expose fractured area; Percutaneous inserts blade plate and accomplishes the fixing of lock screw nail; Embodied the principle of Minimally Invasive Surgical Technology, and how metaphysis does not need bone grafting again.LISS can also be applied in part osteopathia, osteoporotic fracture, or when existing bone damaged, is applicable to total hip replacement or overhauls (long handle type) postoperative homonymy femoral shaft section fracture far away, or the knee joint replacement prosthesis surrounding fracture etc.
Description of drawings
Fig. 1 is the structure chart of the left and right blade plate of the locking bone fracture plate system among the embodiment;
Fig. 2 is the user mode structure chart of said locking bone fracture plate system.
The specific embodiment
See Fig. 1-2, the locking bone fracture plate system that has sighting device of present embodiment comprises: blade plate 1 and sighting device 3 that shape is consistent with the dissection profile of femur or tibia 4; Be distributed with screw hole 11 on the blade plate 1, have respectively on the sighting device 3 with said blade plate 1 on screw hole 11 aim at through hole one to one; Sighting device 3 is set up in the top of this blade plate 1 through a plurality of fairleads 2 that pass said aiming through hole.
Has the center through hole that is used on femur or tibia 4 boring and sends into lock-screw 5 on the said fairlead 2.
The locking bone fracture plate system of present embodiment can be under the situation that does not expose fractured area; Percutaneous inserts blade plate and accomplishes the fixing of lock screw; The soft tissue injury of bony site is eased down to minimum degree, and this product has accurate plasticity, in operation, need not to carry out bending.Product is more stable than like product after installation, allows patient to carry out activity in early days.
Obviously, the foregoing description only be for explain clearly that this utility model does for example, and be not to be qualification to the embodiment of this utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation that these spirit that belong to this utility model are extended out or change still are among the protection domain of this utility model.
Claims (2)
1. a locking bone fracture plate system that has sighting device is characterized in that comprising: blade plate (1) that shape is consistent with the dissection profile of femur or tibia (4) and sighting device (3);
Be distributed with screw hole (11) on the blade plate (1), have respectively on the sighting device (3) with said blade plate (1) on screw hole (11) aim at through hole one to one; Sighting device (3) is set up in the top of this blade plate (1) through a plurality of fairleads (2) that pass said aiming through hole.
2. the locking bone fracture plate system that has sighting device according to claim 1 is characterized in that: have the center through hole that is used on femur or tibia (4), holing and sends into lock-screw (5) on the said fairlead (2).
