Bleeding, for the fusion of centrum provides blood supply, existing processing system of striking off is poorly suitable for Minimally Invasive Surgery, for this present invention is provided
Nucleus pulposus and soleplate processing system under a kind of minimally invasive passage.
The content of the invention
In order to solve the above problems, the present invention provides nucleus pulposus and soleplate processing system under a kind of minimally invasive passage.
The technical solution adopted for the present invention to solve the technical problems is：
Nucleus pulposus and soleplate processing system under a kind of minimally invasive passage, including：
Working beam, one end of working beam is provided with the resilient cutting part of a tool, and the other end has leader；
Sleeve pipe, is set on working beam, and cutting part can follow working beam to be accommodated in sleeve pipe.
The cutting part is set to the resilient sheet metal of a tool, and the two ends of sheet metal all are connected to form ring with working beam
Shape, sheet metal follows working beam to be expanded simultaneously to both sides after removing sleeve pipe.
The cutting part includes some resilient bonding jumpers of tool, and one end of bonding jumper is all connected with working beam, the other end
It is distributed in divergent shape.
The handle is in spherical or ellipsoid, and anti-slip recess is provided with the handle.
The handle is in shaft-like, and handle is vertically arranged with working beam.
Described sleeve pipe is provided with an annular protrusion near the end of handle.
The sheet metal uses stainless steel material.
Described bonding jumper one end is fixed on a mounting blocks, and correspondence mounting blocks are provided with mounting hole on the working beam, pacify
Dress block is located in mounting hole, and laterally interts mounting blocks and mounting hole by a securing rod with fixation.
The cutting part is set to the resilient sheet metal of a tool, and the two ends of sheet metal all are connected to form ring with working beam
Shape, sheet metal follows working beam to be expanded to side after removing sleeve pipe.
The beneficial effects of the invention are as follows：Using the present invention of said structure, when minimally invasive passage is stretched into, cutting part is accommodated in set
In pipe, the external diameter of sleeve pipe is less than minimally invasive passage, can smoothly enter, and when setting position is reached, work is caused by being moved after sleeve pipe
The cutting part of bar stretches out sleeve pipe, and because cutting part has elasticity, cutting part stretches out after sleeve pipe and expands, rotary work bar, using cutting
Cut portion to clear up vertebral endplate, it is seen that the present invention can be at perfect nucleus pulposus and soleplate suitable under minimally invasive passage
Reason, the good completion cleaning work on the premise of original minimally invasive passage is not changed, simple and ingenious structure is very useful, effect
Significantly.

Specific embodiment
1~Fig. 2 of reference picture, as shown is the first implementation method of the invention, under the present invention is a kind of minimally invasive passage
Nucleus pulposus and soleplate processing system, including：
Working beam 1, one end of working beam 1 is provided with the resilient cutting part of a tool, and the other end has leader 2；
Sleeve pipe 3, is set on working beam 1, and cutting part can follow working beam 1 to be accommodated in sleeve pipe 3.
Using the present invention of said structure, when minimally invasive passage is stretched into, cutting part is accommodated in sleeve pipe 3, and the external diameter of sleeve pipe 3 is small
In minimally invasive passage, can smoothly enter, when setting position is reached, cause that the cutting part of working beam 1 stretches out set by being moved after sleeve pipe 3
Pipe 3, because there is cutting part elasticity, cutting part to be expanded after stretching out sleeve pipe 3, rotary work bar 1, using cutting part to vertebral endplate
Cleared up, it is seen that the present invention can perfect nucleus pulposus and soleplate treatment suitable under minimally invasive passage, do not changing original
Completion cleaning work good on the premise of minimally invasive passage, simple and ingenious structure is very useful, effect is significant.
As illustrated, the cutting part is set to the resilient sheet metal 4 of a tool, the two ends of sheet metal 4 all with working beam 1
Connection forms ring-type, and sheet metal follows working beam to be expanded simultaneously to both sides after removing sleeve pipe, and the sheet metal 4 of the structure is easy to receive
Receive, cleaning effect is good, and elasticity is difficult to disappear；The handle 2 is in shaft-like, and handle 2 is vertically arranged with working beam 1；The set
