JPH01284234A - Ultra-sonic wave probe equipped with finder used channel - Google Patents

Abstract

PURPOSE:To make it possible to insert an endoscope while making observation as well as to enhance safety by providing a finder used channel which enables the inserting section of the endoscope to be inserted into an ultra-sonic wave probe wherein ultra-sonic waves are oscillated by a piezo-electric transducer at the tip end of the inserting section to be inserted into a body cavity while an ultra-sonic oscillator is connected with an at-hand section. CONSTITUTION:An ultra-sonic oscillator 2 and an observing section 3 are connected with an at-hand section 1, and a finder used channel 6 communicated with the insertion opening of the at-hand section 1 is formed within an inserting section 4. The inserting section 9 of an endoscope 8 is inserted into a channel 6 through the insertion opening 7. A light source 10 is connected with the endoscope 8, light from the light source 10 is irradiated from a light guide window 11, and the reflected light is received by an image guide window 12 so that observation is made through the ocular section 8A of the endoscope 8. When an ultra-sonic wave probe is inserted into an esophagus through a mouth, a curved pipe section 4A is curvedly operated so that it can be safely inserted as far as a desired position without damaging the inner walls of organs while observation is being made by the tip end of the inserting section 9 of the endoscope 8.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an ultrasonic probe that has an ultrasonic oscillator connected to its hand and generates ultrasonic waves from a vibrator at the tip of an insertion section inserted into a body cavity. be.

[Conventional technology]

The conventional ultrasonic probe has a hand portion 1 as shown in FIG.
An ultrasonic oscillator 2 and an observation section 3 are connected to the insertion section 4, which is inserted into the body cavity from the hand section 1, and a curved tube section 4.
A vibrator 5 for oscillating ultrasonic waves from the ultrasonic oscillator 2 was attached to the tip of the insertion portion 4 via A. When performing transesophageal diagnosis using such an ultrasound probe, the insertion section 4 is inserted into the esophagus blindly.

[Problem to be solved]

With conventional ultrasound probes, when inserting the insertion section 4 into the esophagus blindly, if there is an esophageal cynocele or the like, the patient's life or death may be affected, which poses a safety problem.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an ultrasonic probe with a finder channel that can be inserted into the esophagus while observing the probe, which was conventionally inserted blindly, and has improved safety.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention includes an ultrasonic probe that has an ultrasonic oscillator connected to its hand and emits ultrasonic waves from a vibrator at the tip of the insertion section inserted into a cavity, and an insertion section of an endoscope. It has a finder channel into which you can insert.

[Effect]

In this invention, when inserting the insertion portion of the ultrasound probe into the esophagus, the insertion portion of the endoscope is inserted into the finder channel, and the tip of the insertion portion of the endoscope is projected from the tip of the insertion portion of the ultrasound probe. , the insertion part of the ultrasound probe is inserted while observing the inside of the esophagus, increasing safety.

〔Example〕

Preferred embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, an ultrasonic oscillator 2 and an observation section 3 are connected to a hand portion 1, and a finder channel 6 that communicates with the insertion opening of the hand portion 1 is formed in an insertion portion 4.

The insertion section 9 of the endoscope 8 is inserted into this finder channel 6 from the insertion lower. A light source 10 is connected to the endoscope 8, and the light from the light source 10 is sent to a light guide window 11, and the light emitted from the light guide window 11 and reflected is received by an image guide window 12 and viewed internally. Eyepiece part 8 of mirror 8
It can be observed at A. In this finder channel 6, an upright stand 13 is provided which can be raised and lowered by operating a wire 14.

In the embodiment shown in FIG. 3, a transducer 5 and a finder channel 6 are provided on the side surface of the tip side of the insertion section 4 of the ultrasonic probe.
The one with an opening is shown. An upright stand 13 is also provided at the location of this finder channel 6 (see FIG. 4).

In other embodiments shown in FIGS. 5 and 6, the vibrator 5 and finder channel 6 are formed at different locations.

In any of the embodiments described above, when inserting the ultrasound probe orally into the esophagus or the like, the curved tube section 4A is inserted while observing with the tip of the insertion section 9 of the endoscope 8 inserted into the finder channel 6. By bending the tube, it is possible to safely insert it to the desired location without damaging the inner wall of the organ.

Note that it is also possible to insert a treatment tool such as a puncture needle using the finder channel 6.

〔effect〕

As explained above, according to the present invention, an ultrasonic probe that has an ultrasonic oscillator connected to its hand portion and that emits ultrasonic waves from a vibrator at the tip of the insertion portion that is inserted into a cavity, has an insertion portion of an endoscope. Since we have provided a finder channel through which the ultrasound probe can be inserted, it is now possible to perform transesophageal diagnosis while observing, which was previously done blindly. It becomes possible to insert it inside.
