Abstract
The utility model relates to a bone-grafting pipe of a vertebral body reduction and bone-grafting instrument through a percutaneous vertebral pedicle of a spine, which comprises a funnel 1 and a hollow pipe 2, a plug 3 and a fixing part 4 for a bone-grafting conduit, wherein the upper end of the hollow pipe is connected with the lower end of the funnel 1 through the fixing part 4 for the bone-grafting conduit, the wall of the lower end of the hollow pipe 2 is provided with a hole 21, the plug 3 is arranged in the hollow pipe 2 under the hole 21, the upper end surface and the lower end surface of the plug 3 are slopes, and the lower end of the hollow pipe 2 is in a sharp corner shape. When in use, the bone-grafting pipe 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 bone grafting pipe.
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 the spinal column percutaneous cervical arc root vertebral body reduction bone grafting instrument bone grafting that a kind of surgical wound is little, amount of bleeding is few, the convalescence after Miles operation is short pipe 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 bone grafting pipe, comprise funnel, hollow pipe, plug and bone grafting pipeline fixer, hollow pipe upper end is connected to funnel lower end by bone grafting pipeline fixer, on the tube wall of hollow pipe lower end, have hole, plug is arranged in the hollow pipe of below, hole.
The further technical scheme of this utility model is: upper surface and the lower surface of plug are inclined-plane.
This utility model further technical scheme is: hollow pipe lower end becomes tip-angled shape.
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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1: a kind of spinal column percutaneous cervical arc root vertebral body reduction bone grafting instrument bone grafting pipe, comprise funnel 1, hollow pipe 2, plug 3 and bone grafting pipeline fixer 4, hollow pipe 2 upper ends are connected to funnel 1 lower end by bone grafting pipeline fixer 4, on hollow pipe 2 lower end tube walls, have hole 21, plug 3 is arranged in the hollow pipe 2 of 21 belows, hole, upper surface and the lower surface of plug 3 are inclined-plane, and hollow pipe 2 lower ends become tip-angled shape; On bone grafting pipeline fixer 4, be useful on the radially through hole of fixed funnel 1 and hollow pipe 2, leting slip a remark of funnel 1 lower end is arranged in radially through hole with the upper end of hollow pipe 2, there is locating hole bone grafting pipeline fixer 4 one end, in locating hole, there is dog screw 41, the end of dog screw 41 is positioned at the hole on the tube wall of let slip a remark hole on wall and hollow pipe 2 of funnel 1 lower end, and both are fixed together.
Operation principle of the present utility model and using method are:
When operation, bottom there is is the core bar 6 of flexible chain 5 insert hollow pipe 2 from the import of funnel 1, and locate and fix, move up and down again core bar 6, to depart from the impaired bone of original position by the flexible chain 5 stretching out in the hole 21 from hollow pipe 2 lower end tube walls and push away reduction position, and clean out behind the space of bone grafting, core bar 6 is extracted with prying and pulling lever 7, autologous bone or homogeneous allogenic bone are put into hollow pipe 2 by funnel 1, with push rod by autologous bone or homogeneous allogenic bone by being pushed out in the vertebral body of fracture from hole 21.
