Description
Technical field
This utility model relates to medical instruments field, and the puncture for lumbar intervertebral disc Minimally Invasive Surgery of a kind of improvement is combined
Device.
Background technology
Lumbar intervertebral disc Minimally Invasive Surgery, as the effective Therapeutic Method of one, is recommended for expectant treatment invalid and do not meet waist
The patients with lumbar disc herniation of vertebra open operation indication, has damage little, instant effect, and the cycle of recovering is short, medical expense
The advantage such as low.
It is critical only that of lumbar intervertebral disc Minimally Invasive Surgery accurately punctures the intervertebral disc to pathological changes.But, owing to lumbar vertebra anatomical structure is multiple
Miscellaneous, the vital tissue structure such as including plexus nervorum, intraspinal tube vascular plexus, anterior margin of vertebral body ventral aorta, kidney, therefore, puncturing
During easily cause tissue injury, cause the appearance of bad complication.
The puncture needle head end being presently used for lumbar intervertebral disc Minimally Invasive Surgery is sharp, causes the risk of penetration damage to be difficult to avoid that.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, and the nook closing member head end of puncture needle is improved as circle
Structure, designs the puncture combination unit for lumbar intervertebral disc Minimally Invasive Surgery of a kind of improvement, simple in construction, with low cost, square
Just use, provide a kind of safe puncture combination unit for lumbar intervertebral disc Minimally Invasive Surgery.
The technical solution of the utility model is: the puncture combination unit for lumbar intervertebral disc Minimally Invasive Surgery of a kind of improvement, structure
Including external paracentesis trocar and built-in paracentesis trocar, described external paracentesis trocar is made up of needle body, the pin wing and nook closing member, pin
Body and nook closing member are stainless steel structure, and needle body head end is parallel circular open structure, and nook closing member head end is positioned at outside needle body head end, naked
The head end of dew is circle spline structure, and described built-in paracentesis trocar is made up of needle body, the pin wing and nook closing member, and needle body and nook closing member are stainless
Steel construction, needle body head end and nook closing member head end are sharp spline structure, and needle body head end is concordant with nook closing member head end, described external puncture casing
Pin internal diameter and built-in paracentesis trocar external diameter are corresponding, and external paracentesis trocar and built-in paracentesis trocar are detachable structures.
During use, after patient's good point of puncture of lumbar vertebra skin labelling, broken skin success, external paracentesis trocar through puncturing pricking method
Enter skin, in piercing process, it is possible to use the circle of external paracentesis trocar nook closing member head end pause spline structure separate nerve, blood vessel,
Deng vital tissue, after arriving intervertebral disc, extracting external paracentesis trocar nook closing member, the needle body inwall along external paracentesis trocar is put
Enter built-in paracentesis trocar, utilize the sharp-pointed spline structure of built-in paracentesis trocar needle body and nook closing member head end, thrust intervertebral disc, interior
Putting paracentesis trocar and insert spinal disc interior, extract built-in paracentesis trocar nook closing member, service aisle is successfully established.
This utility model compared with prior art has the advantage that
This utility model simple in construction, with low cost, convenient and practical, set up service aisle offer technology just for lumbar intervertebral disc Minimally Invasive Surgery
Profit, during puncture of lumbar disc, can be prevented effectively from the puncture risks to neighbouring vital tissue, reduce bad medical events and send out
Raw.
Accompanying drawing explanation
Fig. 1 is this utility model external paracentesis trocar structural representation；
Fig. 2 is this utility model built-in paracentesis trocar structural representation；
In figure, reference is: the external paracentesis trocar of 1-, the built-in paracentesis trocar of 2-, 11-needle body, the 12-pin wing, 13-nook closing member, 21-
Needle body, the 22-pin wing, 23-nook closing member
Detailed description of the invention
As it is shown in figure 1, the puncture combination unit for lumbar intervertebral disc Minimally Invasive Surgery of a kind of improvement, structure includes external puncture
The trocar 1 and built-in paracentesis trocar 2, described external paracentesis trocar 1 is made up of needle body 11, the pin wing 12 and nook closing member 13,
Needle body 11 and nook closing member 13 are stainless steel structure, and needle body 11 head end is parallel circular open structure, and nook closing member 13 head end is positioned at pin
Outside body 11 head end, exposed head end is circle spline structure, and described built-in paracentesis trocar 2 is by needle body 21, the pin wing 22 and pin
Core 23 is constituted, and needle body 21 and nook closing member 23 are stainless steel structure, and needle body 21 head end and nook closing member 23 head end are sharp spline structure, pin
Body 21 head end is concordant with nook closing member 23 head end, and described external paracentesis trocar 1 internal diameter and built-in paracentesis trocar 2 external diameter are corresponding,
External paracentesis trocar 1 and built-in paracentesis trocar 2 are detachable structures.
