Abstract

The utility model relates to a B-ultrasonic wave puncture guiding instrument, which comprises a plane surface pothook, and an arc-shaped pothook. A guiding needle head with the angled scales is fixed on the pothook by a pothook screw, and a needle groove dish is arranged in a guiding needle head. The needle groove dish has 3 needle grooves, and the sectional planes of the needle grooves are triangular-shaped. The guiding needle head is pressed tightly on the skin, and the puncture needle can be fixed on the prearrange position by tightening an angled screw. The utility model can press tightly on the skin, with the advantages of strong versatility, simple structure, flexible operation, and adjustable angle as required. The puncture needle can be fixed, and the puncture needle longer than 8 cm is suitable to use.

Description

Universal B-ultrasonic wave puncture guiding instrument

A kind of attachment device of B-mode instrument puncture usefulness.

The B ultrasonic instrument is loaded onto the guiding puncture device, can accomplish person under inspection's internal organs are seen clearly, and punctures accurately, thereby makes the diagnosis of disease and treat simple and easy to doly, is subjected to medical worker and patient's welcome deeply.

From the B ultrasonic perforator of imports such as the U.S., Holland, Japan all is the special plane special use, and promptly the B ultrasonic instrument of each model all has the special-purpose perforator of oneself, can not be general.Though the B ultrasonic perforator of the employing adhesive bonding method that Shanghai produces has improved versatility, has accomplished dress pin adjustable angle, adhesive surface is excessive, and versatility is still not enough, only is applicable to the linear array probe on the B ultrasonic instrument, can not be used for sector probe or irregular probe.In addition, its needle tray is long, only should use long puncture needle, and long puncture needle is difficult to buy, and goes back dependence on import at present.Also have, the adjustment of its dress pin position is cumbersome, changes pin at every turn and all will take off needle tray.

No matter import, still home-made B ultrasonic perforator, all have following two defectives during operation: one is to compress skin, puncture changes direction because of the skin displacement makes pin often, or cause that image rocks.Another is that puncture needle can not be fixed, and pin is mispluged into deep tissues or from predetermined position extract, and the augmenting tissue damaged area causes unnecessary misery to the patient.

The purpose of this utility model provides a kind of universal B ultrasonic guiding puncture device.It is applicable to the B ultrasonic instrument of various models, and it is convenient to accomplish to adorn the pin angle adjustment, can use short puncture needle, can compress skin during puncture and can be fixed on predetermined position to puncture needle.

The purpose of this utility model is achieved in that perforator has a cover plane hook and arc hook.Hook can bond on the linear array probe or sector probe of B ultrasonic instrument, and the guide pin head of hook key screw band angle index is fixed on the hook, and the needle tray dish is placed in the guide pin head and can freely rotates.It has three with upper section needle tray triangular in shape, so that lay the different puncture needle of various thicknesses.There is an annular slot side of needle tray dish, and the angle screw on the guide pin head can put in the draw-in groove.During puncture, the guide pin head is pressed on the skin, after puncture puts in place, utilizes the angle screw to make the needle tray dish compress puncture needle, makes puncture needle be fixed on predetermined position.

Compare with existing various perforators, the utlity model has following advantage:

1. highly versatile.Not only be applicable to various import B ultrasonic instruments, also be suitable for the various not old-fashioned instruments of subsidiary perforator.

2. angle is adjustable as required, can dealing with various requirements.

3. can compress skin when operating, fixedly puncture needle can reduce the unnecessary damage that causes because of operate miss, alleviates patient's misery.

4. be applicable to the various puncture needles more than 8 centimetres, short lumbar puncture needle also can reach the puncture purpose.

5. simple in structure, flexible operation, its manufacturing cost is lower than similar products at home and abroad.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structure diagram according to the universal B ultrasonic perforator that the utility model proposes.

Fig. 2 is a perforator needle tray dish view.

Fig. 3 is a perforator plane hook view.

Fig. 4 is a perforator arc hook view.

Describe the concrete structure and the working condition of universal B ultrasonic perforator in detail below in conjunction with accompanying drawing.

As shown in Figure 1.This utility model has the hook (1) that can bond on the Ultrasonic-B probe, hook screw (2) is suspended to hook (1) to guide pin head (3) and goes up and fixed, needle tray dish (4) is placed in the guide pin head (3) and can freely rotates, and the lateral margin of guide pin head (3) has the angle screw (5) of angle index on it to be fixed on needle tray dish (4) on the angle position of needs.

Needle tray dish (4) has A, B, three cross section needle trays triangular in shape of C, the base width of groove can select different sizes to cooperate as required, the base width that its optimum size cooperation is A, B, C is respectively 1.8,1.6,1.4 millimeter, or be respectively 1.2,0.9,0.7 millimeter is so that lay the different puncture needle of various thicknesses.There is an annular slot side of needle tray dish (4), and angle screw (5) can put in this draw-in groove, to reach the purpose that tightens up.

This utility model has two kinds of hooks.A kind of is the less plane hook (referring to Fig. 3) of sticking face, and another kind is an arc hook (referring to Fig. 4).The cambered surface radius of arc hook is 5～30 millimeters, so that bond on the probe of B ultrasonic instrument of various different models.

The puncture procedure process is as follows: at first with hook screw (2) guide pin head (3) be suspended in advance with the bonding hook of B ultrasonic instrument probe on, tighten hook screw (2), tighten up perforator.Unscrew angle screw (5) then, rotate needle tray dish (4), puncture needle is inserted corresponding needle tray (pin can move up and down) in this needle tray, and align with required angle index.Compress needle tray dish (4) at last, tighten angle screw (5), guide pin head (3) is pressed on the patient skin, can puncture.After pin is punctured to predetermined position, unscrew angle screw (5), rotate needle tray dish ∥ (4), use little No. one needle tray instead and compress puncture needle, tightening angle screw (5) can be fixed on predetermined position to puncture needle once more.
