Specific embodiment
In the following, being carried out in conjunction with the ultrasound guided puncture bracket for foramen intervertebrale lens performed the operation of the attached drawing to the utility model detailed
Explanation.
The ultrasound guided puncture bracket for foramen intervertebrale lens operation of the utility model comprising: ultrasonic head fixed frame
11, puncture needle limiting slot 12.
Ultrasonic head fixed frame 11 surround the periphery of ultrasonic head and by the ultrasonic guidance for being used for foramen intervertebrale lens operation
Bracket is punctured to be fixed on ultrasonic head.
Puncture needle limiting slot 12 is connected to the side of ultrasonic head fixed frame 11, and puncture needle limiting slot 11 defines puncture needle
Movable plane；The movable plane of puncture needle is overlapped with the plane of ultrasound that ultrasonic hair goes out.The width in 12 gap of puncture needle limiting slot
Uniformly, the width in gap is preferably formed into 1.8mm to degree.
As described in Figure 1, it is ring-type, the circumferential profile of inner circumferential profile and ultrasonic head that ultrasonic head fixed frame, which is integrally formed 11,
It is corresponding.
The first screw hole is formed on ultrasonic head fixed frame 11, the first bolt 13 passes through first screw hole and is resisted against ultrasound
On the periphery of head, thus ultrasonic head fixed frame is rigidly secured on ultrasonic head.
As shown in Figure 2,3, ultrasonic head fixed frame 11 includes main frame 11a, upper plug-in unit 14a, lower plug-in unit 14b.
Main frame 11a is formed as the closed U-shaped structure of the first side opening, second side, and upper plug-in unit 14a is inserted in main frame 11
Open side upper end, lower plug-in unit 14b is inserted in the lower end of the open side of main frame 11；Upper plug-in unit 14a and lower plug-in unit 14b is logical
The second bolt 13a connection is crossed, it is possible thereby to the distance between plug-in unit 14a and lower plug-in unit 14b be adjusted, so that fixed frame 11 can
To be clamped on various sizes of ultrasonic head.
As shown in Figure 2,3, the upper end of the open side of main frame 11a is formed with slot 15a, and upper plug-in unit inserts 14a at this
In upper slot 15a, third bolt 13b passes through the side wall of upper slot and is resisted against the surface of plug-in unit, thus fixes upper plug-in unit
In upper slot.
The lower end of the open side of main frame 11a is formed with lower slot 15b, and lower plug-in unit 14b is inserted in the lower slot 15b,
4th bolt 13c passes through the side wall of upper and lower slot and is resisted against the surface of lower plug-in unit, and thus lower plug-in unit is fixed in lower slot.
The fixed frame 16 for fixing puncture needle limiting slot 12 is formed on the outside of ultrasonic head fixed frame 11；Fix 16 middle parts
Be formed as screw rod 17；Nut 18a, 18b there are two being formed on screw rod 17；Through-hole is formed on the end 12a of puncture needle limiting slot 12,
It is covered on the screw rod 17, and is clipped between two nuts 18a, 18b by the through-hole, thus to the position of puncture needle limiting slot 12
It can be adjusted and fix, so that the ultrasonic face that puncture needle limiting slot 12 goes out with ultrasonic hair is completely coincident.
By the ultrasound guided puncture bracket for foramen intervertebrale lens operation of the utility model, puncture needle can be fixed on and wear
The accuracy that remote ultrasonic guidance intervertebral foramen punctures (i.e. in plane of ultrasound), improves in the plane in thorn target spot institute；It punctures simultaneously
Needle planar can be moved flexibly, convenient for planar adjusting inserting needle direction.The utility model is simple and reliable for structure, is easy to make
It makes, using safe, the learning curve of ultrasound guidance foramen intervertebrale lens operation puncturing can be greatly shortened, while helping to reduce doctor
Raw and patient x-ray radiation dosage.
