Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a sword guide tool for a medical MN wave scanning device. ``)'', ``J and the ``device 1'' device are needles (for example, t and biopsy needles). Such guide kg tool is super I
It is intended to be attached to a single-wave J-scanning head.

The ultrasonic meal apparatus 1 of the type used for medical diagnosis is well known. The scanning device is shade 1i
A historical sword was used to form a two-dimensional cross section of f4 and 715th position scanned on the screen of the i+j ray tube (C1 and 1). Dimensions. W Bamboo M, the scanning device can also be used to assist in needle intermediaries during medical procedures (+!/! I mean, the suction of fluids from about 1 Sls inside the body, mutual or 1'1's of life). Noshiru. If there is a dispute, the friend event 11゛ichigo 1 will be 1. - Tofu Hiromi With this, the sword'i 1 ゛ 1 round 1〆 v 2 yohi' - 1, self y' 1
Form a screen of 1 dust CRl that hits the inner stone'lj of \N.

4M, when the J-i wave sensor rotates 7ζ is jhk moving when using a lance juicer, the middle cutter sensor formed is generated from the lance juicer and receives III/c. ~ Corresponds to the body part Nurainu in the mosquito plane. In this way, in order to observe the organ in which the needle is inserted, and at the same time observe the wire being inserted, and to place the foot accurately, Therefore, it is desirable to have a mounting bracket attached to the ultrasound scanning head, which holds the needle inserted during the medical procedure. The reed mounting bracket can be adjusted by attaching it to various types of needles, and these needles are designed to be adjusted at the angle of the valley, and the wires can be adjusted in between. It would be desirable to have a mediator on the plane of the sonic scan.In addition, the ultrasonic set meal head can be cooled with a valley 'At/Kojoha', or it can be easily removed from the whole life pρ. I wish I could.

According to the present study, a needle guide gH for an ultra-M wave scanning head is provided. Such a needle guide X can be easily overused on the ultrasonic scanning head and can be stably fastened in a continuous position on the scanning head. Rui Iimi 6M

Of course, the fixture includes means for fixing the V so that the angle at which the needle enters the patient can be adjusted.

Medical - Adjustable dH tool for bamboo wave scanning mount is +IJ
Includes a sheet metal assembly with means for connecting the scanning device to the pupil. Furthermore, it is on the mounting plate above! Take it with lll pin (=
Then, by moving the plane of ultra-thin wave scanning, we can encompass the bihot tentative total. The pivot plate has a part that accommodates this (=1 provisional identification angular position vcN). A needle alignment &i#'f single stage (including at least one needle alignment device) is attached to the pivot. The matching means is
It is adapted to hold the needle biased against the means in a PI motion. The play plate is attached to the pivot plate with an axis pin. The player has a surface diameter byanu means for ad Kenji. Finally, the 8g tool is transferred to the adjustable plate diameter bias means by adjusting the idle plate to the needle alignment means of the entire pivot plate! A) includes a spring Pi which biases the needle towards the full needle alignment reservoir means located between the needle alignment gFi+ setting and the adjustable needle straightener means.

Hereinafter, the present invention will be described in more detail based on the accompanying drawings.

FIG. 1 is a top view of an example of the guide device of the present invention that is housed in the cutting head of the cutting head, FIG. 2 is a front view of the needle guide device shown in FIG. 1, and FIG. 3 is a needle guide. df4Ji4: A top view of the plate (=j), FIG. A front view of the needle guide 8g tool is shown.

1 and 2, a preferred example needle guide device 10 of the present invention is shown. In particular, if you refer to FIG.
It is attached to an ultrasonic scan head 14 of a type commonly known in the art.

In particular, the ultrasonic scan head may be a Type 0 Model 725 scan head manufactured by Atopanne I. Technology Laboratories, Inc. of Belney, Washington. The ultrasonic scanning head 14 has a round shoulder 16 (shown in shading in FIG. 1). At a point around the shoulder 16, a notch fits into the constant portion 18 (shown in FIG. 2) of the clamp 12. Therefore, when attaching the needle guide device 10 to the scanning head 14,
It will always be mounted in a fixed position. As will be clear from the following description, the sword 20 held by the guide device 10 always has a supert? Aligned with the plane of the survey.

The sword guide device 10 is shown in FIG. 3)+'l 4'J plate 2
5, the mounting plate 22 has a substantially triangular shape. One slave plate has a pivot hole 24 at the apex of the triangle and an arcuate hole 26 at the edge of the triangle. Mounting plate 22
is attached to the clamp 12.
0 can be replaced by a clasp rather than the J-sleeve type mechanism 30 (FIG. 2).

Furthermore, the needle guide ah 10 includes a pivot plate 32. As shown in FIG. 12, the pivot plate 32 is
=The top 22 of the J plate 22 is attached. Pivot plate 32
has a pair of needle wheels 34 and 36 on its upper surface. In a preferred embodiment of the invention, the needle a is a roller 34, 36 with a V-shaped surface, as shown. However, instead of rollers 34 and 36, a non-rotating needle aligner can be used at Q. Screwed Rondo 38

Adjust the position of the aligner 34, 36 relative to the scan head 14 by loosening the knob 40 and adjusting the angle of the pivot plate 320.

The second part of the pivot plate 32 has an opening 42 with a spring. Adjustment 11J'+ on the upper side of the play plate 426
It has a stop number 1 shift bias means (for example, the idler roller 44 used in the preferred embodiment of the present invention).

The idler plate 42 is biased by the spring 46, so that the idler roller 44 tends to push against the - side of the needle 2o, and the two needle lockers 34 and 36 of the pivot plate 32 are Hold the needle 2C1 in the fixed position. One end of the two-part spring is held in the spring mounting hole 25 shown in FIG. 3V.

Furthermore, sufficient visibility of the specific needle 20 used in this study is provided. In this way, it is not necessary to have a size adjuster because it can be easily inserted into the eyebrows, or easily removed. By means of the needle collecting rollers 34, 36 and idle rollers 44, which pivot to the 1" peak, the blood of the needle 20000000000000000000 is given to the needle 2000,000,000,000,000,000,000,000. , Small V (sword ゛2oVc) withholds sufficient Tsukimushi Kakusho and neglects scales.

Mutual implementation of the 6th anniversary! The entire surface of the tiger features a protruding wall 27, which is distorted by the sterile sheath that typically covers the scanning head 14 during IJ scans or similar procedures.
, to prevent division into eight. During operation, the protruding wall 27 is connected to the alignment R@34.36 and the idler roller 441.
It's useful to make it go in the direction of o.

Next, in Fig. 42-5, another preferred implementation of the present study is shown in which the sword guide plate x 10 is increased by 9 points.

This needle guide 10 is shown in FIGS. 4 and 5 and is substantially the same as the needle guide described with reference to FIGS. 1-3. Therefore, since the same references are used to explain the same parts in Figures 42 and 5, further explanation of those parts will be omitted here.

This makes it possible for the idler roller 44 to drive the needle 20 through the v-1 neck 56Vc. As will be obvious to those skilled in the art, in this specific example 2, the narrow and relatively soft needle 20 is fixed and supported by a portion that is longer than the needle in the first embodiment.

As may be seen in the field, certain aspects of the present invention provide two different means of attack.

First, the angle of the needle 20 can be adjusted by changing the angle at which the pivot 32 is aligned with the mounting plate 22. Second, the spring bias play plate 42 (play roller 44
