Description
Technical field
The utility model relates to the field of medical instrument technology, the specifically a kind of solid screw thread of foramen intervertebrale lens operation
Stick.
Background technique
The foramen intervertebrale lens technology that doctor is used clinically for treatment protrusion of lumber intervertebral disc, lumbar spinal stenosis etc. can shorten patient
Operating time reduces joint of vertebral column damage and stability destruction, the generation for reducing the complication such as intraoperative hemorrhage and nerve root injury
Rate.Common percutaneous foramen intervertebrale lens technology is to belong to one kind of TESSYS technology.Current clinically used modus operandi is in office
Fiber crops are lower to keep patient awoke, by the way that surgical work conduit is directly placed into canalis spinalis by diameter 6-8mm wound, removes on part
Articular process sclerotin simultaneously expands intervertebral foramen, prominent or prolapsus nucleus pulposus is removed by intervertebral foramen direct view under endoscope and can detect lateral crypt,
The tissue such as intervertebral foramen, oppresses patients' neural to release, and reduction of patient lumbocrural pain symptom has compared with conventional open art formula
Wound is compared with small, bleeding is few, spinal stabilization structure destroys the advantages that relatively small；In addition, patient can in the course of surgery with patient into
Row is linked up, and is carried out continuing assessment to patient symptom, is reduced the incidence of iatrogenic nerve root injury.Clinically have increasingly
More doctors and patient selects using lumbar vertebral diseases such as the treatment of percutaneous foramen intervertebrale lens technology LDH, LSSS.Percutaneous foramen intervertebrale lens are being controlled
More traditional OLD modus operandi can significantly shorten the patients surgery time in terms for the treatment of the lumbar vertebral diseases such as LDH, LSSS, reduce operation wound
And intraoperative hemorrhage, promote patient early out-of-bed activity the advantages that.
Nevertheless, percutaneous foramen intervertebrale lens technology still among continuously improving, is put as placed working column in previous operation
Before being placed at intervertebral foramen, processus articular superior sclerotin need to be inserted into intervertebral foramen in Kirschner wire top to processus articular superior tip, kirschner needle tip
Then internal orifice is inserted into trepan through protection sleeve pipe, cut off lateral margin in processus articular superior and extract trepan to the bone tissue of intervertebral hole mouth
It is inserted into " hollow lead rod " with after Kirschner wire, reaches nucleus pulposus prominent position for guidance working column in lower step.This is not only
Extend operating time, also increase to a certain extent damage in patient's art, amount of bleeding, in art the complication such as neurotrosis hair
Raw rate.
Therefore those skilled in the art should also solve the above problems in time.
Summary of the invention
The purpose of this utility model is that provide a kind of foramen intervertebrale lens operation solid threaded bar for above-mentioned problem,
It is characterized by: structure includes solid metal stick, fixator and three-jaw connector composition, wherein solid metal stick one end is blunt nosed,
Referred to as blunt nose portion, blunt nose portion are provided with rolled thread at 0.3mm backward, the solid metal stick other end by three-jaw connector and
The central through hole of fixator is fixedly connected sequentially, and fixator and three-jaw connector are spirally connected fixation.
Preferably, the solid metal stick length is set as 250mm, diameter is set as 2mm, and the length of rolled thread is set
It is set to 20mm.
Preferably, described fixator one end is round handle, the other end is provided with the external screw thread connecting with three-jaw connector
Connecting pin.
Preferably, the three-jaw connector is the dedicated three valves spring collet of electrical grinding machine, through hole shape is set as among three-jaw connector
Concentric co-axial is set as with fixator through-hole.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are: described in the utility model
Technical solution in doctor's foramen intervertebrale lens minimal invasive surgical procedures, doctor find accurately be suitable for target puncture position, along casing insert
Enter in the bone hole of lesion side superior articular process of lumbar vertebra and penetrate articular process along the angle of canalis spinalis and reach canalis spinalis formation bone road, rolls spiral shell
The design of line, can be pressurizeed Minor articulus position sclerotin of erasing by screw thread, while existing surgical instrument being avoided to be easy to erase
Processus articular superior sclerotin smash, even bone block drops to intraspinal tube, and be difficult to situations such as completely taking out.And in discovery insertion disease
When the bone hole track of change articular process is bad, adjustment angle can be back-outed by opposite direction at any time.The design of blunt nose portion, which avoids, to be penetrated
Articular process sclerotin injures a possibility that intraspinal tube nerve fiber.The utility model structure improve it is simple, rationally, be easily achieved, fit
It closes and promotes and applies.
