Abstract
The invention discloses an intervertebral disc puncture positioning instrument, which comprises an upright rod; three cross rods are fixed along the upright rod and are provided with moving rods which can move along the cross rods; moving rod positioning components are arranged between the cross rods and the moving rods; and the moving rods are provided with puncture needle guide holes. The positioning instrument can accurately determine a circular track from joints above and below human body ilium and waist 5-sacrum protruding to nucleus pulposus of intervertebral disc by means of a computer during operation so as to make the puncture needle guide holes on the three moving rods positioned on the circular track to form arc positioning. Because three points which are on the same plane and not in the same straight line can determine a circle, matched arc needles pass through the three positioned puncture needle guide holes from top to bottom, and a puncture needle can accurately enter the nucleus pulposus of the intervertebral disc along the circular track determined by the computer to complete puncture.
Description
Technical field
The invention belongs to surgery device, particularly relate to a kind of intervertebral disc puncture positioning instrument.
Background technology
The intervertebral disc puncture technology is one of key technology of various intervertebral disk hernia minimally-invasive treatments, the doctor places puncture needle in the intervertebral disc under the guiding of equipment such as X-ray, CT, the doctor should correctly avoid blood vessel, nerve and diverse bone types structure in the piercing process, and puncture needle is placed corresponding position.
Lumbar intervertebral disc protrusion people middle part of the side 4-5 (L4-5), waist 5-sacrum 1 (L5-S1) are outstanding occupies sizable ratio.L4-5, L5-S1 intervertebral disc puncture be difficulty especially.Clinically the L5-S1 puncture time spent very long, often take place because the thing of the abandoning cure that can not correctly puncture.
Intervertebral disc puncture positioning instrument in the market all adopts the mode of straight line puncture, the position relation of the last inferior articular process D of ilium C and waist 5-S1 has determined that can the puncture of puncture needle E straight line successful, suppose, the A point be ilium C on outer a bit, B point representative is gone up on the inferior articular process D outside a bit, A, B point and waist 5-sacrum intervertebral disc at grade, it is the (see figure 1) of determining through the track that fibrous ring H enters nucleus pulposus F that puncture needle E crosses A, B point straight line puncture.Horizontal range between A, the B point is short more, and puncture needle E top is the closer to veutro G, and when A, B horizontal range during for very little or zero, puncture needle E can't puncture and enter (see figure 2) in the nucleus pulposus F.Adopt the straight line puncture can't finish puncture working in this case.
Summary of the invention
Technical problem to be solved by this invention provides a kind of intervertebral disc puncture positioning instrument that can accurately finish puncture.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of intervertebral disc puncture positioning instrument comprises vertical rod, is fixed with three cross bars along vertical rod, and cross bar is provided with the carriage release lever that can move along cross bar, is provided with between cross bar and the carriage release lever and makes the localized carriage release lever positioning element of carriage release lever; Carriage release lever is provided with the puncture needle pilot hole.
Further technical scheme is:
Adopt chute to cooperate or threaded engagement between described cross bar and the carriage release lever.
Another kind of technical scheme of the present invention is: a kind of intervertebral disc puncture positioning instrument, comprise vertical rod, and be fixed with three longitudinal rods along vertical rod, longitudinal rod is provided with the cross bar that bar longitudinally moves, and cross bar is provided with the carriage release lever that can move along cross bar; Be provided with between longitudinal rod and the cross bar and make the localized cross bar positioning element of cross bar, be provided with between cross bar and the carriage release lever and make the localized carriage release lever positioning element of carriage release lever; Carriage release lever is provided with the puncture needle pilot hole.
Further technical scheme is:
Between described longitudinal rod and the cross bar, all adopt chute to cooperate or threaded engagement between cross bar and the carriage release lever.
The present invention's employing does not pass through to regulate carriage release lever (perhaps cross bar and carriage release lever) at three groups of carriage release levers of sustained height, make puncture needle pilot hole on the carriage release lever can camber be positioned the plane at their places. can accurately determine through the last inferior articular process of human body ilium and waist 5-sacrum circular trace (radian of circular trace varies with each individual according to different patients) by computer during operation to nucleus pulposus, make three puncture needle pilot holes on the carriage release lever be positioned at camber location on this circular trace. because not 3 on same straight line in the same plane can determine a circle, three puncture needle pilot holes that use supporting arc pin to pass from top to bottom to have good positioning, just the circular trace that puncture needle is determined along computer accurately can be entered in the nucleus pulposus F and finish puncture. if carry out the straight line puncture, only need in three puncture needle pilot holes, to select any two and use the straight line lancet puncture, can finish the function of straight line puncture.
In addition, the present invention adopts the circular arc puncture needle to substitute the straight line puncture needle, when the circular arc puncture needle rotates along the center of circle of locus circle, the track of 2 motions overlaps on the pin, when therefore the circular arc type puncture needle was around center of circle motion, the resistance in tissue also was minimum, and influence also is minimum.
The present invention has solved the localized problem of intervertebral disc puncture preferably.Use the difficulty that the present invention can solve L4-5, L5-sacrum intervertebral disc piercing process, improve puncture success rate.Use this puncture locator in piercing process, do not need the doctor to hold pin continuously, in X-ray when irradiation,, the doctor can hide to outdoor or other is local, has avoided medical personnel's X-ray to shine repeatedly.Simultaneously, the circular arc type puncture locator possesses the function of straight line puncture.
Further specify technical scheme of the present invention below in conjunction with accompanying drawing.
