Abstract
The utility model discloses a supersonic guided B-ultrasonic wave guiding puncture needle for interventional therapy of diseases, which belongs to the field of medical equipment. The utility model is composed of a main ruler, an auxiliary ruler, a guide, a fixing frame, etc., wherein, the fixing frame is fixedly connected with one end of the main ruler; the tail end of the auxiliary ruler is fixedly connected with the guide; the connecting point between the auxiliary ruler and the main ruler and one end near the guide is provided with a locking screw for making the position of the puncture needle relatively stable. The utility model overcomes the disadvantages of high cost, etc. of existing special probes. The utility model has the advantages of strong practicality, high accuracy, easy use and low cost.
Description
This utility model relates to the employed B ultrasonic ultrasonic puncture of the interventional therapy disease device under a kind of ultrasonic guidance, belongs to medical instruments field.
B ultrasonic guiding down puncture technique be a kind of easy, safety, economy, rapidly, the little and effective clinical treatment method of damage, but because of its employed dedicated probe costs an arm and a leg, factors such as utilization rate is lower, and limited popularizing of this technology, thus increased the financial burden of asking the doctor.
The purpose of this utility model be to provide a kind of practical, degree of accuracy is high, easy to use, B ultrasonic ultrasonic puncture device that puncture angle is adjustable, cheap.
This utility model adopts following technical scheme to realize: it is by main scale (1), secondary chi (2), guider (3) and fixed mount formations such as (4), fixed mount (4) is fixedly connected on an end of main scale (1), main scale (1) is circular arc, flexibly connect with secondary chi (2), the back side of main scale (1) is provided with arc-shaped rack (5), the front of secondary chi (2) is provided with gear (7), and the back side is provided with adjustment screw (6), and tooth bar (5) is meshed with gear (7).The end of secondary chi (2) is fixedly connected with guider (3), guider (3) inside is provided with guide pad (8), guide pad (8) but demolition, with the needs of the puncture needle that adapts to different model, guide pad (8) fixes by the guider lock-screw (10) that is connected the outside; For guarantee secondary chi (2) in use with main scale (1) relative fixed, the end in secondary chi (2) and main scale (1) connection near guider (3) also is provided with lock-screw (9).
This utility model is simple in structure, and is cheap and easy to use, accurate, can reduce the spending of patient medical expense more than 50%, alleviates unnecessary misery, also makes hospital reduce equipment expense simultaneously.
Fig. 1 is an overall structure sketch map of the present utility model
Fig. 2 is the A-A cutaway view of Fig. 1
Fig. 3 is the B-B cutaway view of Fig. 1
Among the figure: the secondary chi of 1-main scale, 2-, 3-guider, 4-fixed mount,
5-tooth bar, 6-adjustment screw, 7-gear, 8-guide pad,
9-lock-screw, 10-guider lock-screw
The contrast accompanying drawing is done further detailed description to this utility model below: adopt stainless steel material to make as shown in the figure each parts through processing respectively, then fixed mount is connected on the main scale with rivet, tooth bar is welded on the back side of main scale again; After gear and adjustment screw be welded to the front and back of secondary chi respectively, the guider that will install guide pad and guider lock-screw more is welded on the secondary chi, then secondary chi is installed on the main scale, lock-screw is screwed on the secondary chi at last, can obtains B ultrasonic ultrasonic puncture device described in the utility model.
