Abstract
The utility model relates to a flexible chain for a vertebral body reduction and bone-grafting instrument through a percutaneous vertebral pedicle of a spine, which comprises an upper joint 1, a plurality of middle joints 2, a lower joint 3 and a plurality of connection pins 4, wherein the middle joints 2 are movably connected with the upper joint 1 through the connection pins 4, the middle joints 2 are gradually movably connected through the connection pins 4, the lower joint 3 is movably connected with the middle joints 2 through the connection pins 4, the bottom surface of the lower joint 3 is a plane, and each of the joints can rotate around the connection pins 4. When in use, the flexible chain disclosed by the utility model is arranged on the vertebral body reduction and bone-grafting instrument through the percutaneous vertebral pedicle of the spine, so that the problem that in the traditional open operation, the skin is cut, and the tissues are moved, to expose the bone-grafting inlet point of the chest and wrist fracture zygopophysis (into the vertebral body from the vertebral pedicle) can be avoided, the tissue wound and amount of bleeding in the operation can be reduced, therefore solving the problems that in the traditional open operation, the rehabilitation time is long, and the postoperative complications are many. Compared with the prior art, the flexible chain disclosed by the utility model has the characteristics of simple structure, stability, reliability, low manufacture cost, and the like.
Description
Technical field
This utility model relates to a kind of orthopedic medical device, particularly a kind of spinal column percutaneous cervical arc root vertebral body reduction bone grafting instrument flexible chain.
Background technology
Human spine's lumbar vertebra compression fracture adopts conventional therapy treatment more, needs to cut skin by opening in therapeutic process, and pedicle is implanted into autologous bone or homogeneous allogenic bone to the vertebral body of injured lumbar vertebra compression fracture.Because this operation process will be through cutting skin, tissue is dialled from steps such as appearing of, breast waist anterior vertebral articular process just can reach therapeutic purposes.The shortcomings such as exist tissue injury large, hemorrhage many, rehabilitation duration is long, and postoperative complication is many.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of spinal column percutaneous cervical arc root vertebral body reduction bone grafting instrument flexible chain is provided.
The technical solution of the utility model is: a kind of spinal column percutaneous cervical arc root vertebral body reduction bone grafting instrument flexible chain, and include under a upper joint, some middle joints, one and save and some connecting pins, there is connector the lower end of upper joint, has connection pin-and-hole on connector; There is U-joint the upper end of middle joint, has connection pin-and-hole on U-joint, and there is connector the lower end of middle joint, has connection pin-and-hole on connector; There is U-joint the upper end of lower joint, has connection pin-and-hole on U-joint; Middle joint is flexibly connected with upper joint by connecting pin, and some middle joints are flexibly connected section by section by connecting pin, and lower joint is flexibly connected with middle joint by connecting pin, and the bottom surface of lower joint is plane, and each joint all can rotate around connecting pin.
This utility model is arranged on spinal column percutaneous cervical arc root vertebral body reduction bone grafting instrument while use, avoid the incision of skin of conventional therapy, dial from tissue, appear the bone grafting inlet point (pedicle enters vertebral body) of breast pelvic bone folding articular process, reduce amount of bleeding in tissue injury and operation, solved the difficult problem that conventional therapy rehabilitation duration is long and post-operative complication is many, compared with prior art, there is overall structure simple, reliable and stable, the features such as low cost of manufacture.

The specific embodiment
As shown in Figure 1: a kind of spinal column percutaneous cervical arc root vertebral body reduction bone grafting instrument flexible chain, save by a upper joint 1, some middle joints 2, under one 3 and some connecting pins 4 form, there is connector 11 lower end of upper joint 1, has the pin-and-hole of connection 12(as shown in Figure 2 on connector 11); There is U-joint 21 upper end of middle joint 2, has the pin-and-hole 22 of connection on U-joint 21, and there is connector 23 lower end of middle joint 2, has the pin-and-hole of connection 24(as shown in Figure 3 on connector 23); There is U-joint 31 upper end of lower joint 3, has the pin-and-hole of connection 32(as shown in Figure 4 on U-joint 31); Middle joint 2 is flexibly connected with upper joint 1 by connecting pin 4, and some middle joints (2) are flexibly connected section by section by connecting pin (4), and lower joint 3 is flexibly connected with middle joint 2 by connecting pin 4, and the bottom surface of lower joint 3 is plane, and each joint all can rotate around connecting pin 4.
When use, the fixing welding in core bar 5 lower ends (as shown in Figure 5) by upper joint 1 with spinal column percutaneous cervical arc root vertebral body reduction bone grafting instrument, core bar 5 is inserted bone grafting pipe 7 from funnel 6 imports of spinal column percutaneous cervical arc root vertebral body reduction bone grafting instrument, can carry out reduction bone grafting operation.
