Abstract
The invention relates to an auxiliary spine internal fixation device capable of reinforcing the intensity of an internal fixation system in the operation of the spine internal fixation, and a use method of the auxiliary spine internal fixation device. The auxiliary spine internal fixation device is composed of an auxiliary rod, a plurality of connectors and a plurality of fastening screws, wherein the auxiliary rod and the connectors can be directly fixedly connected, or can be connected through auxiliary rod grooves designed on the connectors, the other sides of the connectors are provided with main rod grooves used for connection with a main rod, in design, one independent main rod groove can be adopted for connecting the main rod between two fastening screws, two main rod grooves spaced at a certain distance also can be adopted, Y-shaped design is adopted, and the main rod grooves adopting the design can be used for connection with the main rod on the two sides of the fastening screws. The auxiliary spine internal fixation device is made of titanium alloy, magnesium alloy or a stainless steel material having good biocompatibility. With the adoption of the device, the intensity of the internal fixation system can be greatly improved, and thus the occurrence of complications such as rod breakage and angle loss can be reduced.
Description
Technical field
The present invention relates to a kind of for internal fixation of spine time can strengthen the spinal column auxiliary inner fixing device and using method thereof of internal fixation system intensity, the present invention can be greatly improved the intensity of internal fixation system, thus reducing the generation of the complication such as disconnected rod, loss angle.
Background technology
Spinal fracture, spinal column degenerative disease, the deformity of spine such as skoliosis, once reach surgical indication, it is necessary to the various operative treatments of row.The spinal column the rebuild stability that in needing, fixing offer is good.The current interior fixing nail-stick system included based on pedicle screw and pitman, also has various os integumentale screw systems, and hooks bar system, vertebral plate strap system etc., but these systems are required for, and a pitman is fixing to be connected.Clinically, much serious fracture, deformity of spine, tumor resection etc. are performed the operation, the requirement of strength of pitman is higher., also often there is the complication of pitman fracture in even some simple spinal surgeries.If the pitman insufficient strength of some patient, even if not rupturing, also result in the complication such as RA loss.
Summary of the invention
In order to reduce pitman fracture, the generation of the complication such as RA loss, we devise this spinal column auxiliary inner fixing device, and this device can be greatly enhanced the interior fixing intensity of pitman.The present invention realizes by the following technical solutions:
1, the present invention is by auxiliary rod, some connexons and some fastening screws composition, auxiliary rod and connexon can pass through directly fixing connection, auxiliary rod groove and the connexon that can also pass through design on connexon connect, trip bolt is screwed into connexon by the screw on connexon, makes auxiliary rod in the auxiliary rod groove of connexon or main rod tightly maintains static in the main rod groove of connexon after tightening.
2, the side of connexon can directly be fixed with auxiliary rod, an auxiliary rod groove can also have been designed, auxiliary rod is placed in auxiliary rod groove, above auxiliary rod groove, design has several screws, adopt the method tightening fastening screw that auxiliary rod is fixed in auxiliary rod groove, connect if fixing, need the auxiliary rod of design different length, surgeon selects the auxiliary rod being suitable for use, if connexon design has auxiliary rod groove, the connection of itself and auxiliary rod is exactly revocable, need to select to intercept suitable auxiliary rod according to operation, manual operation makes auxiliary rod groove that auxiliary rod passes through on connexon and connexon connect voluntarily.
3, the opposite side of connexon is provided with main rod groove, for connecting with main rod, main rod is connected to the fixing screw that some distances do not wait, main rod is connected on human spine by fixing screw, therefore, the design of main rod groove can be an independent main rod groove, this main rod groove is for connecting the main rod (such as Fig. 2) between two pieces of fixing screws, main rod groove can also be two main rod grooves being separated by a distance, in " Y " font, this design can connect on the main rod of fixing screw both sides (such as Fig. 8), because the distance fixed on main rod between screw can change along with the actual range of spinal column different segment, therefore, such two kinds of designs select this device of different designs scheme to implement operation when substantially can solve different distance.
4, auxiliary rod can be a simple cylindrical structure, and two ends are all without the directly fixing connexon connected；Can also being one end and connexon directly fixing connection, the other end be without the directly fixing connexon connected；Can also be that two ends all have directly fixing connection connexon；Can also be that other of auxiliary rod are arbitrarily provided with the directly fixing connexon connected in certain position.
5, the present invention adopt titanium alloy that bio-compatible is good or or magnesium alloy or stainless steel material make.
