Description

The medical thrust guiding device

Technical field

This utility model relates to a kind of medical apparatus and instruments, specifically a kind of medical thrust guiding device.

Background technology

Usually adopt the mode of percutaneous puncture disease is diagnosed and to be treated clinically, the outstanding advantage of this method is an invasive, no matter is diagnosis or treatment, and patient's post-operative recovery is all very fast.Therefore, this method is applied in clinically more and more.At present, in clinical piercing process, be blind wearing sometimes, be to be undertaken sometimes by image documentation equipments such as B ultrasonic, CT or MRI.Blind inaccuracy of wearing is well imagined, and the puncture under the guiding of image documentation equipments such as B ultrasonic, CT or MRI, owing to execute the real-time imaging that the art doctor can not obtain inserting needle, can't adjust the needle angle and the degree of depth immediately, after inserting needle can only be waited,, adjust deviation more on demand according to scanogram.Though can monitor piercing process in real time by B ultrasonic, the poor definition of image can't be preserved data, and can only be confined to use at the puncture of part organ.Because the inaccuracy of the percutaneous puncture that above situation caused, the related side effects of operation and the chance of complication are increased, and the success rate of operation reduces, therefore, whether can obtain timely, safe and effective treatment for doctor's clinical treatment work and patient, bring a lot of adverse effects.

The utility model content

The purpose of this utility model just provides a kind of medical thrust guiding device so that puncture needle exactly inserting needle reduce the puncture risk to the target location of human body, improve the success rate of clinical percutaneous puncture operation.

This utility model is achieved in that on the substrate both sides and is provided with guide rail that the guide rail upper bracket has goes up bent double track frame, is equipped with and can moves and localized template along the rail frame, is installed with some arranged in column pin holes on the template between the double track frame.At first, the substrate of this medical thrust guiding device is placed the front portion of CT bed or MRI bed, double track is placed on the guide rail of substrate both sides, moves forward and backward the double track frame, vertically to be adjusted to the position that needs of patients punctures.Then, again template is moved along the double track frame, with horizontal adjustment and aim at the concrete position that to puncture.After adjusting position and location, the some simulation pins of reuse pass the pin hole on the template, are inserted to the skin of human body down.At last, utilize CT or MRI that simulation pin of the every row on the template and inserting needle route are carried out tomoscan, determine simulation pin position and the needle angle that certain is suitable according to scanning result, that this position is is suitable, the inserting needle position of puncturing accurately.By the analysis scan result, go back the degree of depth that simultaneously measurable goes out to need inserting needle.Execute the art doctor by this position, angle and degree of depth puncture inserting needle after, inserting needle is to patient's diseased region exactly.Therefore, use this device guiding carrying out percutaneous puncture operation, can increase the accuracy of puncture procedure, reduce the puncture risk, improve the success rate of percutaneous puncture operation.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a partial structurtes decomposing schematic representation of the present utility model.

The specific embodiment

As shown in Figure 1 and Figure 2, this medical thrust guiding device is to place on CT bed or the MRI bed 1 to use.The shape of substrate 8 is suitable mutually with CT bed or MRI bed 1, and the gentle slope shape is made at the back edge place, so that the patient feels more comfortable.Be fixed with inverted T-shaped guide rail 2 on the both sides of substrate 8, the two ends footing support of double track frame 5 is on guide rail 2.Double track frame 5 is established relatively, for symmetric two irregular upward bending arc shape moulding, with the breast abdominal part of outer housing human body.On the footing of double track frame 5 roller 7 can be installed, be beneficial to move forward and backward.Preferably be connected to stationary links 12 between the homonymy footing of double track frame 5, realize the same moved further of double track frame.

On the riser face of guide rail 2, have row's aperture, on the footing of double track frame 5, have corresponding aperture,, can carry out longitudinal register the double track frame by inserting alignment pin.Also can on the double track frame, make a few row's apertures up and down,, adapt to the patient of different fat or thin builds to adjust the height of double track frame 5.Also not perforate on the riser face of guide rail 2, but, locate double track frame 5 by the dog screw that outside the footing of double track frame 5, spins.The footing of double track frame 5 also can be made into a kind of flexible up and down adjustable version, to adjust the height of double track frame, adapts to the patient of different fat or thin builds.

Have relative groove on double track frame 5, inboard notch is big, and the notch in the outside is little.In groove, be embedded with steamboat 11, locate by axostylus axostyle 10 cross-under.Template 4 is located by axostylus axostyle 10 cross-under between two rail framves of double track frame 5.As shown in Figure 2, on template 4, have the through hole parallel with the plate face, grafting axostylus axostyle 10 in the through hole, the two ends of axostylus axostyle 10 pass the groove on the double track frame 5 after passing steamboat 11 in double track frame 5 grooves, its outer end nut 6 that spins.This structure can realize being slidingly connected of template 4 and double track frame 5.If screw nut 6, can the position of fixed form 4 on double track frame 5.

Among Fig. 2, only there is an axostylus axostyle 10 to be plugged in the lower end through hole of template 4, is provided with two 90 ° angle indicator board 3 in the both sides of template 4.The drift angle place perforate of angle indicator board, correspondence are set on the axostylus axostyle 10 of fixed form 4.In the perforate of an edge of angle indicator board, after another axostylus axostyle 10 of cross-under, this axostylus axostyle passed groove and the steamboat 11 in the groove on the double track frame 5, external part was by nut 6 locking that spins.Edge at angle indicator board 3 has arc-shaped slot, and the end, two sides of template 4 upper ends is provided with overhanging semi-convex axle 9, semi-convex axle 9 arcuate grooves that pass on the homonymy angle indicator board 3, the nut locking that spins of its end.Semi-convex axle 9 slides in arcuate groove, and just can make template 4 serves as that axle rotates adjustment with the axostylus axostyle 10 that passes its lower end, to adapt to the special angle requirement of human body different parts.

Be carved with the angle graticule in the inside edge of angle indicator board 3, thereby can obtain the prompting of different needle angles, the Template Location angle is had a quantized value accurately, in order to the preservation of data.In like manner, on double track frame 5, also can cut out scale mark, whether concordant with convenient observation template 4 fixed positions.On guide rail 2, also can cut out length mark, whether concordant with the fixed position of convenient observation double track frame 5.

Be installed with some arranged in column pin holes on template 4, the size of pin hole adapts with the diameter of simulation pin and puncture needle.Stencil design has certain thickness, so that the degree of depth of pin hole can guarantee the inserting needle direction.For satisfying different percutaneous puncture operations, puncture stencil design of the present utility model has the template of the different model, aperture and the distribution density that adapt to 22G, 20G and the special use of 18G puncture needle, and the external form size of various templates is consistent.The simulation puncture needle that is applied on this puncture guiding device also is divided into different models such as 22G, 20G and 18G, its length unanimity.
