Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an in-vivo probe such as an ultrasonic diagnostic apparatus and a cover thereof, and more particularly to an in-vivo probe having a guide hole of a puncture needle in a body inserted into the body cavity and a cover thereof.
[0002]
[Prior art]
In recent years, ultrasonic diagnostic apparatuses have been used to observe tissues and the like in living bodies in the medical field. In general, an ultrasonic diagnostic apparatus is composed of an in-vivo probe inserted into a body cavity and an ultrasonic observation apparatus placed outside the living body. The body cavity probe inserted into the body cavity is provided with an ultrasonic transmission / reception unit at the tip thereof. When performing an ultrasonic diagnosis, an ultrasonic wave is transmitted from the ultrasonic transmission / reception unit while the intracavity probe is inserted into the body cavity, and the ultrasonic wave reflected from the living body is received by the ultrasonic transmission / reception unit. Then, a received signal from the ultrasonic transmission / reception unit is processed by an ultrasonic observation apparatus and displayed on a monitor or the like, thereby observing a tissue in the living body.
[0003]
In such an ultrasonic diagnostic apparatus, it is often performed to collect a diseased tissue or the like with a puncture needle while performing ultrasonic observation. For this reason, the body cavity probe of the ultrasonic diagnostic apparatus is provided with a puncture needle guide hole penetrating the body inserted into the body cavity, as described in, for example, Japanese Patent Laid-Open No. 5-84249. There is.
[0004]
Generally, the puncture needle is so-called “disposable” that is disposed after use, but the body cavity probe is expensive and is reused after cleaning and disinfection. Conventionally, in a body cavity probe that does not have a puncture needle guide hole, in order to prevent the body cavity probe from adhering to body fluids, blood, etc., and to facilitate cleaning and disinfection, A cover is put on the main body to be inserted into the body.
[0005]
[Problems to be solved by the invention]
A conventional cover for a body cavity probe that does not have a puncture needle guide hole completely covers the body inserted into the body cavity of the body cavity probe, and covers the body cavity probe that has a puncture needle guide hole. If it is used for a tentacle, the cover will be broken by the puncture needle passed through the puncture needle guide hole. For this reason, the body cavity probe having the puncture needle guide hole is used as it is without attaching a cover, or in a state where the cover is torn, and the body inserted into the body cavity and the puncture needle provided in the body Body fluid, blood, etc. adhered to the inside of the guide hole, making it difficult to clean and disinfect.
[0006]
An object of this invention is to provide the body cavity probe which can suppress the contamination of the main body inserted in a body cavity, and the puncture needle guide hole provided in the main body.
[0007]
Another object of the present invention is to provide a body cavity probe cover capable of suppressing contamination of the main body inserted into the body cavity of the body cavity probe and the puncture needle guide hole provided in the body body. .
[0008]
[Means for Solving the Problems]
An in-vivo probe according to the present invention is an in-vivo probe in which a puncture needle guide hole is provided in a main body to be inserted into a body cavity. A body cavity probe cover provided with a guide hole cover portion for covering is provided.
[0009]
Further, the body cavity probe cover according to the present invention is a body cavity probe cover in which a puncture needle guide hole is provided in a body inserted into the body cavity, and covers the surface of the body cavity probe body. A main body cover portion for covering and a guide hole cover portion for covering the inside of the puncture needle guide hole of the body cavity probe are provided.
[0010]
The main body cover part is made of a film-like material having elasticity, little acoustic attenuation, and ultrasonic transmission, and its film thickness is very thin. The main body cover portion is formed to cover the main body of the body cavity probe, and is provided with an opening through which the puncture needle passes at a position corresponding to the outlet of the puncture needle guide hole of the body cavity probe.
[0011]
The guide hole cover portion is made of a flexible material having a strength that does not break even when the tip of the puncture needle hits. The shape of the guide hole cover portion is tubular, and the outer diameter is as large as it passes through the puncture needle guide hole of the body cavity probe, and the inner diameter is as large as the puncture needle passes. Openings through which the puncture needle passes are provided at both ends of the guide hole cover part, and the opening on the outlet side of the puncture needle guide hole is coupled to the opening of the main body cover part without any gap.
[0012]
