Description

A kind of percutaneous lumbar intervertebral foramen of 3D positioning punctures navigator

Technical field

The utility model is related to measurement for diagnostic purposes, it is related to puncturing navigator field, espespecially a kind of 3D positioning warp Skin lumbar intervertebral foramen punctures navigator.

Background technology

Percutaneous lumbar intervertebral foramen puncture is will to puncture to be needled between lumbar vertebrae, to lumbar vertebrae intracavitary injection of medicine and foramen intervertebrale lens under marrow The Clinics of core enucleation.In the prior art, when medical staff punctures, it is difficult to reach that puncture needle is disposable It is formed directly into lumbar intervertebral foramen, it is difficult to reach and settle at one go, influence operating time and increase patient's pain.

Invention content

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of 3D to position percutaneous lumbar intervertebral foramen puncture Navigator.Being intended to, which can instruct percutaneous lumbar intervertebral foramen to puncture, is accurately positioned, and reduces the x lines exposure of medical worker and patient, reduces disease The wound of people improves the precision of operation, shortens operating time, reduces pain and the bleeding of patient, reduce the hair of accidental injury It is raw.

Technical solution adopted by the utility model to solve its technical problems is：There is provided a kind of 3D positioning percutaneous lumbar intervertebral foramen Puncture navigator, including body, it is characterised in that：There are two mutually perpendicular horizontal detections in the horizontal direction above body Pipe, there are a two length scale rulers in both sides below body, there is corresponding with the length scale ruler both sides of one end respectively above body The second graduated scale, the second graduated scale is directed toward at 20cm at length scale ruler 10cm from 17cm, and every 2 ~ 4mm etches diameter The guiding groove for being 1mm for 2mm depths.

Further：

The body is the cuboid of long 24cm, width 2.5cm, high 5.8cm.

The block upper surface is printed on intervertebral foramen and controls entry point scale with reference to table to body surface distance and puncture angle.

The side of the body can also be used there are one horizontal detection pipe when facilitating patient lying-on-side.

The utility model has the beneficial effects that：Percutaneous lumbar intervertebral foramen can be instructed to puncture to be accurately positioned, reduce medical worker and The x lines of patient expose, and reduce the wound of patient, improve the precision of operation, shorten operating time, reduce the pain of patient and go out Blood reduces the generation of accidental injury.

Description of the drawings

The utility model will be further described below in conjunction with the accompanying drawings.

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the utility model principle figure.

In figure：1 it is body, 2,3,4 be horizontal detection pipe, 5 be infrared level meter socket, 6 is infrared level meter button, 7 With reference to table, 8 it is the second graduated scale, 9 is length scale to controlling entry point scale to body surface distance and puncture angle for intervertebral foramen Ruler, 10 are guide groove.

Specific implementation mode

Referring to attached drawing, a kind of 3D of the utility model positions percutaneous lumbar intervertebral foramen and punctures navigator, including body 1, feature It is：There are two mutually perpendicular horizontal detection pipes 2,3 in the horizontal direction above body 1, both sides there are two length below body 1 Graduated scale 9 is spent, there are second graduated scale 8 corresponding with the length scale ruler 9, the second quarter in the both sides of 1 top one end of body respectively Ruler 8 is spent from 17cm at direction length scale ruler 10cm, every 2 ~ 4mm etches the guiding that a diameter of 2mm depths are 1mm at 20cm Groove 10.

In the embodiments of the present invention：

The body 1 is the cuboid of long 24cm, width 2.5cm, high 5.8cm.

1 upper surface of the body is printed on intervertebral foramen and controls entry point scale with reference to table 7 to body surface distance and puncture angle.

Operation principle is puncture point referring to Fig. 2, wherein E, and B is target point（It is known）, AD is navigator height, and BD is lesion Highly（It is determined by CT examination）, ED is known, then AC=(AB*ED)/DB, is required.Then angle beta can be asked after AC determinations.

When work：

1. measuring the body surface distance BD of targeted vertebral body intervertebral foramen by Clinical CT or MRI survey tools；

2. taking prone position, Kirschner wire to position intervertenral space patient, is determined according to disc herniation direction and punctures oblique line angle, It is used in combination marking pen to identify；

3. set navigator on preoperative positioning oblique line, the other intersection point for opening 2cm and oblique puncture line centered on starting point, using putting down Line principle calculates the puncture access that navigator should select（Corresponding scale has been calculated in advance, and body surface is arrived according to intervertebral foramen Distance immediately arrives at needle angle control point, and navigator has done etching line in advance）, the position line for placing it in preoperative mark is good Horizontal ruler has an optimistic view of anterior-posterior horizontal according to preoperative vertebra localization top rake, selects 1/3 top rake, introversion to puncture, reaches Saturating l spine ap ＆ lat when 12cm, in time adjustment puncture direction.

In the second embodiment of the utility model, navigator front end is furnished with the socket 5 of infrared level meter, can adapted cross Laser generator, measurement accuracy of improving the standard.

Groove 10 is oriented to play the guiding role to paracentesis needle.

There are one horizontal detection pipes 4 for the side of the body, are used when facilitating patient lying-on-side.

Claims (4)

1. a kind of 3D positions percutaneous lumbar intervertebral foramen and punctures navigator, it is characterised in that：Have above body two in the horizontal direction Mutually perpendicular horizontal detection pipe, there are a two length scale rulers in both sides below body, above body the both sides of one end have respectively with Corresponding second graduated scale of the length scale ruler, the second graduated scale is from 17cm to being directed toward length scale ruler 10cm at 20cm Place, every 2 ~ 4mm etch the guiding groove that a diameter of 2mm depths are 1mm.

2. a kind of 3D according to claim 1 positions percutaneous lumbar intervertebral foramen and punctures navigator, it is characterised in that：The body It is the cuboid of long 24cm, width 2.5cm, high 5.8cm.
