It is small, easy disinfection, the high -temperature sterilization does not influence the apparatus precision, does not account for the operating table space, non -staining operating field territory, but its location principle and design wide application to the operation of various internal deeps location and the developmental research of multiple special locator.
Description
Technical field
This utility model relates to field of medical article technology, is specifically related to a kind of spinal puncture localizer.
Background technology
Spinal puncture localizer, for the Needle localization of the internal deep a certain target spot of spinal column, is particularly used in intervertebral foramina, vertebra
The Needle localization at each positions of spinal column such as intercalated disc, articular process and pedicle of vertebral arch.
Along with the development of the clinical departments such as Minimally invasive procedure, scope spinal surgery, Pain Management and department of neurology, many Wicresofts
Operation is required for guiding location to arrive target spot, surgical lesion or operation path, such as foramen intervertebrale lens operation, percutaneous by puncture needle
Pedicle screw internal fixation, intervertebral disc radio-frequency ablation procedure, Nerve Root Block anesthesia art etc..
But the target spot in spinal column deep or operative region are minimum, closing on surrounding has many important nerves, blood vessel and interior internal organs
Official's cincture, also needs to avoid blocking of hard osseous tissue sometimes.Patient will be in strict accordance with the operation inserting needle approach of Design
Arrive target spot, could safely and conveniently arrive preferable operative region, it is to avoid serious postoperative complication or sequela occur.But
For new hand, patient generally requires Fluoroscopy location repeatedly, repeatedly adjusts the direction of puncture needle, angle and the degree of depth, just can obtain
Obtain safe inserting needle path and satisfied tip position.Repeated localised puncture repeatedly has an X-rayed misery and the x-ray radiation adding sufferer, prolongs
Grow operating time, increased operation risk and infect possible, even if even repeated localised puncture location is the most not necessarily obtained in that reason
The target position thought, thus significantly reduce operative effect.
Meanwhile, in prior art, level indicator is fixed on instrument or base, and body surface or operation aseptic area are not
Smooth, then acquisition horizontal plane is extremely difficult and loses time, and once needs to change puncture position or mobile and horizontal instrument base
Time, need again to readjust horizontal plane, readjust parameter, waste time and energy.
Utility model content
In order to overcome above-mentioned technical problem, this utility model provides a kind of spinal puncture localizer.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of spinal puncture localizer, including positioning rule, bevel protractor, correcting magnet, level indicator, described bevel protractor is semicircle
Shape, the circle centre position at string is provided with installing hole, described positioning rule and puncture conduit and is fixed at installing hole by angle locking switch,
And it is dynamic all can to turn around the center of a circle；When bevel protractor, positioning rule and puncture conduit all do not have to rotate around the center of circle, triangular angle
Being 0 °, the most described puncture conduit axis is consistent with positioning rule axis；While using angle locking switch stationary positioned chi
The fixing conduit that punctures, thus adjust the needle angle puncturing conduit；Be totally released angle locking switch time, can by puncture conduit with
Bevel protractor separates, thus is individually stayed on puncture needle by puncture conduit, and described positioning rule dorsal part is additionally provided with correcting magnet.
Also multiple puncture conduits can be weldingly fixed on the bevel protractor back side, the axis of described puncture conduit is directed to angle
The center of circle of chi, by anglec of rotation chi, makes shape between puncture conduit and positioning rule axis at a certain angle, thus adjusts and wear
The needle angle of thorn conduit, also protects category at this patent.
Because having certain thickness between positioning rule, bevel protractor and puncture conduit three, puncture needle from puncture conduit by rear with
Positioning rule does not have fixing spacing distance between same level, puncture needle and positioning rule, therefore, selects a block length square
Magnet, for correcting magnet, be fixed on the positioning rule back side.
Spacing distance between the thickness of described correcting magnet with puncture needle to positioning rule is consistent, it is simple to location, works as puncture
Pin is after puncture conduit passes through, and just the surface with the correcting magnet being attached to positioning rule end is in same plane.
Further, described localizer also includes that detachable height gauge, described detachable height gauge are vertically mounted on location
On the major axis of chi, and can slide along positioning rule major axis, be fixed on positioning rule major axis by height gauge hook knob.
Further, described detachable level indicator can be fixed on the back side, front and the two sides of positioning rule, as required side
Obtain horizontal plane the most flexibly.
Further, the angle initiating terminal of described positioning rule, with described positioning rule axis as standard, can be in location
The middle point identification of indication end on chi, it is also possible to for the pointer on positioning rule axis.
Further, described positioning rule front is provided with at least one graduation mark, generally one or two, described scale
Line scale with positioning rule end as beginning or end, described positioning rule end point identification in positioning rule location mid-shaft is provided with.
Being provided with a graduation mark at the long axis in axis in the described positioning rule back side, described graduation mark scale with bevel protractor circle centre position is
Starting point, positioning rule end midpoint is designated terminal.
Further, described height gauge is provided with graduation mark, and described graduation mark scale is arranged in positioning rule with height gauge
Time, the position, axis of positioning rule is starting point, and the end of height gauge is terminal.
Further, described bevel protractor positive and negative is equipped with scale.
The operation principle of described spinal puncture localizer is by a three-dimensional operation puncturing passage, by along body
Positioning rule on table orthographic projection line is converted into the two dimensional surface being perpendicular to ground, then punctures the specific of conduit by bevel protractor locking
Two dimensional surface is converted into by needle angle has the one-dimensional straight line of certain degree, then from point of puncture inserting needle, along wearing with horizontal plane
Thorn duct direction proceeds to length-specific, i.e. needle tip arrives target spot.
Beneficial effect:
Puncture locator simple in construction described in the utility model, it is simple to produce and safeguard, simple to operate, real in available Rhizoma Atractylodis Macrocephalae
Shi Dingwei, punctures direction check and correction convenient directly perceived, punctures precision high, and easy to use, Needle localization is the most accurate, it is simple to again puncture
Location target spot.Volume is little, easily sterilizes, and high-temperature sterilization does not affect apparatus precision, does not account for operating-table space, not contaminated operation region,
Its positioning principle and design can be widely applied to operation and the developmental research of multiple positioner special of location, various internal deep.
