Abstract
This utility model belongs to medical field, for the puncture procedure under ultrasonic wave added, the negative-pressure adsorption formed by silicon rubber suction cup and sucker pressing plate is in ultrasonic probe side, the right-angle relationship utilizing itself and probe to be formed and the distance between the probe that can survey and target area, one is simulated from point of puncture to the oblique line of target area after respective value being inputted computer, the namely course of puncture needle, this line of suitable adjustment through over-angle can point to target area intuitively, instructs puncture procedure.
Description
Technical field
This utility model belongs to medical field, is specifically related to a kind of sucked type puncture angle positioner that ultrasound guidance assists puncture.
Background technology
Ultrasound-guided Biopsy is that doctor arrives a kind of therapy of patient body inner tissue structure by ultrasonic auxiliary puncture needle, all less to patient trauma, expense.But because separating between pricker and probe, need to operate respectively, when puncturing, repeatedly just will can find target area by inserting needle, doctor will could be competent at this work through clinical practice for many years.Therefore the fixed mount patent of a lot of assist physician puncture has been invented, such as application number: 201120377296.0, name is called a Chinese patent of " a kind of ultrasonic puncture guide frame ", this is a kind of ultrasonic puncture guide frame, the shape of ultrasonic probe has a variety of, the design of this patent and the connection of probe can not adapt to the multiformity of ultrasonic probe, and the support body of this Patent design can not regulate length, the multiple demand of clinical puncture can not be adapted to.Therefore design a kind of can by sucker suction on the ultrasonic probe of various shape, puncture supporter body can regulate length and intuitively to show the ultrasonic puncture angle positioning device of puncture path necessary.
Summary of the invention
Sucker type ultrasonic puncture angle positioner, is made up of angle adjustment dish (above having angle index), puncture needle positioning pipe, length adjustment knob, length adjustment bar (above having length scale), silicon rubber suction cup.
Silicon rubber suction cup utilizes negative-pressure adsorption in the side of probe.After input related angle, length value, draw up the advance route of puncture needle through computer mould, very intuitively.
Accompanying drawing explanation
Fig. 1 is sucker type ultrasonic puncture angle positioner schematic diagram: 1 is puncture needle positioning pipe; 2 is angle adjustment dish (above having angle index); 3 is skin penetrating point; 4 is length adjustment bar (above having length scale); 5 is length adjustment knob; 6 is silicon rubber suction cup; 7 is ultrasonic probe; 8 is ultrasonic probe side; 9 is puncture needle; 10 is target area; 11 is the imaginary vertical line of ultrasonic probe center to target area; 12 is skin; 13 is the dummy line of point of puncture to target area; 14 is supersonic sounding region, and 15 is right angle.
Fig. 2 is the triangle schematic diagram made in corresponding diagram 1: A is right angle; B is angle adjustment dish; C is ultrasonic probe center; D is skin penetrating point; E is target area.
Detailed description of the invention
The detailed description of the invention that this utility model technology adopts is: as shown in Figure 1, first the target area 10 needing puncture is detected with ultrasonic probe 7, the negative-pressure adsorption that this utility model is formed by silicon rubber suction cup 6 is in ultrasonic probe 7 side (a certain predetermined altitude value), make this utility model parallel with skin 12, silicon rubber suction cup 6 other end has screw, silicon rubber suction cup 6 can be fixed on probe for a long time, and it is just passable that each operation only needs to change other parts; Angle adjustment dish 2 has angle value above, obtains an angle value by the Needle localization pipe 1 adjusted above it; Adjustment length adjustment knob 5 and length adjustment bar 4 obtain a length value; Ultrasonic probe 7 is placed in directly over target area 10, fictionalizes one by the imaginary vertical line 11 of ultrasonic probe center to target area with computer, a length value can be recorded.
The length on a limit of known right angled triangle, an angle value obtained by adjustment puncture needle positioning pipe, according to Pythagorean theorem and trigonometric function, just can extrapolate the hypotenuse length of this right angled triangle, namely point of puncture is to dummy line 13 length of target area, going out this line with computer simulation is presented on the display screen of Ultrasound Instrument, if the point of puncture that during actual puncture, computer simulation goes out does not arrive target area 10 to the dummy line 13 of target area, then suitably adjust the angle of angle adjustment dish 2, until point of puncture arrives target area 10 to the dummy line 13 of target area.Like this, whole puncture procedure is just very directly perceived, and the doctor lacked experience also can grasp this puncture technique fast.
Fig. 2 is the triangle schematic diagram made of corresponding diagram 1, equals the angle of B, A is right angle, ask the length of DE line according to the length of known AB line, the length (a certain predetermined altitude value) of AC line, the length of CE line, the angle of B, the sharp angle of D.
The process needing computer to calculate is exactly equal according to right angled triangle E angle the sharp angle that 90 degree deduct D, calculates the line length of CD, then calculates the line length of DE according to Pythagorean theorem, finally simulate DE line on a display screen according to trigonometric function.
