Description
Technical field
The present invention relates to the field of medical instrument technology, the lumbar puncture needle group with positioning and coloring function is particularly related to
Part.
Background technique
Lumbar puncture is diagnosis neurology department's illness, spinal anesthesia, canalis spinalis administration, spinal canal myelography, banishes cerebrospinal fluid etc. and perform the operation
In indispensable inspection and treatment method.The lumbar puncture needle that most domestic uses at present is traditional " Kui Ken Shi " lumbar vertebrae
Puncture needle is made of stainless steel needle core, stainless steel lumbar puncture needle and needle stand, disadvantage is that: 1, it is by stainless steel
Material is made, during Reusability, it is likely that because disinfection, which is not thorough, is caused cross-infection；2, since its needle body is very thin
When into lumbar vertebrae be difficult to control needle body direction of travel, not only increase lumbar surgery difficulty return patient cause it is unnecessary
Pain；3, it in use " Kui Ken Shi " lumbar puncture needle, operates in drainage process since csf flow cannot be observed directly
Amount has the case where spraying outside cerebrospinal fluid for the patient of high cranium pressure, hernia cerebri danger easily occurs so needle core must be fully drawn out
Other Cerebrospinal Fluid in Patients over floods can also be brought a series of sequelae such as postoperative intracranial hypotension, headache by danger to it；4, its
It is to be made of stainless steel, it is expensive.
The retrieval existing applying date is 2006.04.17, application No. is the utility model patent of CN200620012881.X public affairs
A kind of new disposable lumbar puncture needle external member is opened, mainly by needle core, lumbar puncture needle, guidance needle and fixator group
At needle core is placed through in lumbar puncture needle, and guidance needle guard is through at outside lumbar puncture needle, guidance needle pedestal and lumbar puncture needle pedestal
Between be equipped with a fixator, guidance needle pedestal can screw in fixator, lumbar puncture needle pedestal and guidance needle pedestal on be all provided with
There is the card slot of same structure to blocking boost motor.Although the patent devises the structures such as guidance needle, but there are still very much
Deficiency intact can not solve the above problems.
Firstly, the effect of the fixator, the relative positioning being only intended between guidance needle and lumbar puncture needle, not
Realize the opposite fixation for puncturing patient of lumbar puncture needle, the mode relative to traditional puncture needle Direct perforantes has no very big reality
Matter progress, there is no good positioning actions, and due to operating error and foozle, and guidance needle is worn with lumbar vertebrae
Free gap between pricker will increase position error；Secondly, in drainage there is still a need for needle core is extracted, in this way in connection drainage dress
Draining hole is to not only result in the loss of cerebrospinal fluid in open exposed environments and cause hernia cerebri, but also increase when setting
Infection probability, transparent plastics can only Fuzzy Observation to whether having cerebrospinal fluid when drainage, can not see the flow of cerebrospinal fluid,
It can not learn that the flow velocity of water, the small the patented product of size can not be observed at all as people observe the water in transparent water pipe
The flow of cerebrospinal fluid；In addition, cannot accurately know whether to puncture in place in puncture process, it is easy to cause excessively to puncture
Danger, this can bring irreversible grievous injury to patient.
Summary of the invention
For the deficiency in above-mentioned background technique, the present invention proposes the lumbar puncture needle group with positioning and coloring function
Part solves the existing lumbar puncture needle technical problem that paracentesis depth is uncontrollable when puncturing, positioning is inaccurate.
The technical scheme of the present invention is realized as follows: there are the lumbar puncture needle assemblies of positioning and coloring function, including
Mutually matched guidance needle, lumbar puncture needle and needle core, the needle core are inserted into the inner wall after lumbar puncture needle with lumbar puncture needle
Mutually from, several perforation are offered on the circumferential surface of the lumbar puncture needle, the guidance needle is fixed in positioning seat, position

Seat and drainage footstock offer colour developing slot be connected to vertical through-hole in the pedestal that develops the color, filled with for cerebrospinal fluid in colour developing slot
Developing solution, drain and offer communication port on footstock, drainage footstock is switched equipped with the revolution matched with communication port.
Piercing deep calibration is provided on the outer peripheral surface of the lumbar puncture needle, the holding end setting of lumbar puncture needle helps
Push plate is provided with docking groove and internal screw thread on the pushing assisted plate, be provided on the end of needle core the snap ring matched with docking groove,
With the external screw thread of screw-internal thread fit.
The revolution switch is the revolving body being arranged in drainage footstock, drains in footstock and offers turned cavities, revolving body
It is rotatably arranged in turned cavities, the vertical through-hole and revolving body are coaxial, offer on the inside of revolving body and are connected to vertical through-hole
Inlet, inlet is connected with communication port, and the height of inlet is greater than the difference in height between two adjacent perforateds, the company
Port is connected with syringe by hose.
The top of the revolving body is provided with rotating disc, and the vertical through-hole and rotating disc are coaxially disposed.
The positioning seat includes the left clip and right clip being mutually clamped, and the side that left clip is docked with right clip offers
Clamping groove is connected on right clip and matches snap ring with clamping groove.
The colour developing slot is back-shaped slot, and one end that colour developing slot is connected to vertical through-hole is provided with flaring slot, is flared the height of slot
Degree is greater than the difference in height between two adjacent perforateds.
To be set in the tubular shell drained on the outside of footstock, the side wall and communication port of tubular shell seal the revolution switch
Cooperate, the liquid outlet with communication port activity cooperation is provided on the side wall of tubular shell, liquid outlet is connected with injection by hose
Device.
The colour developing slot is back-shaped slot, and one end that colour developing slot is connected to vertical through-hole is provided with flaring slot, is flared the height of slot

Position seat is fixed on patient skin, has fully ensured that the Stability and veracity of positioning, is avoided patient's shake and is caused to misplace.
In addition, drainage footstock has drainage, avoided multiple plug needle core and caused to infect, also effectively reduced outside cerebrospinal fluid
The occurrence of spray, and then a series of generation for sequelae such as avoid hernia cerebri.The pedestal that develops the color has coloration, when lumbar vertebrae is worn
After pricker is penetrated into certain depth, cerebrospinal fluid can be flowed into first by the gap between needle core and lumbar puncture needle in colour developing slot,
It reacts with the developing solution in colour developing slot, can learn that in time lumbar puncture needle has penetrated in place；If lumbar puncture needle is
Certain depth is penetrated, still loses colour developing slot discoloration, while having red liquid appearance, then can learn positioning failure in time, then
Localised puncture is re-started, avoids and subsidiary injury is caused to patient.It is pierced into the setting of deep calibration, is not only convenient for wearing for the first time
When piercing the control of depth, and check, it can be referred to according to the last depth for puncturing record.The present invention is being drawn
When cerebrospinal fluid, do not need extract needle core, by drain footstock can be realized, rotate back to turn on pass opening for communication port can be realized
It closes, avoids the risk of infection and sequelae generation.
