Abstract

PROBLEM TO BE SOLVED: To easily wash and sterilize a probe body and an insertion path part of an ultrasonic probe consisting of a clamping part, the insertion path part and an ultrasonic sensor by providing the probe with a freely attachable and detachable treatment implement to the insertion path part. SOLUTION: A semicircular groove 10 is formed along the longitudinal direction of the circumferential flank of the insertion path part 61 consisting of a metallic pipe inserted with a cable 63. The diameter of a pipe made of a resin is formed to a slightly larger than that of the groove 10 and the length thereof to approximately the same as that of the groove 10. When the pipe is mounted at the groove 10 of the main body, the pipe is fitted into the groove 10 from its circumferential flank by utilizing the elasticity of the pipe itself. At this time, the groove 10 and the pipe are so arranged and formed that the ultrasonic scanning sectional axis by the ultrasonic sensor 62 and the central axis of the pipe are aligned. When the main body of the ultrasonic probe is washed and sterilized after operation, the pipe is removed from the groove 10 and is discarded and the main body and its groove 10 are washed and sterilized.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an abdominal ultrasonic probe connected to a medical ultrasonic diagnostic apparatus.

[0002]

2. Description of the Related Art Currently used medical endoscopes include:
As shown in FIG. 5, the main body includes a grip 50, an insertion path 51, and a mirror 52. In the main body, the grip 50 serves as an entrance, from which the insertion path 51
There is provided a processing tool insertion path 53 made of a Teflon tube or the like that reaches the mirror unit 52 through the processing unit. For example, a treatment tool is inserted into the insertion path 53 to remove a part of a polyp or the like generated in the stomach.

FIG. 6 shows a conventional probe for the abdominal cavity, which is composed of a main body composed of a grip part 60, an insertion path part 61, and an ultrasonic sensor 62, and a connector 64 connected to the main body through a signal cable 63. It is configured. This conventional abdominal cavity probe does not have a processing tool insertion path like an endoscope.

[0004]

In the case of an abdominal probe, a processing tool insertion path is provided similarly to an endoscope, and a doctor inserts a treatment tool (forceps) into the insertion path while a doctor views an ultrasonic image. And puncture needles), which can be used for appropriate treatment have been expected. A method of providing a hollow in the main body of the probe for abdominal cavity of FIG. 6 and inserting the tube of the endoscope of FIG. 5 into this hollow is one method, but in this plan, the insertion path itself is formed in a tubular shape. As it is formed, it is difficult to clean and sterilize this tube portion after surgery. That is, it takes time and effort to remove the dirt attached to the inner wall of the tube and sterilize the inside of the tube.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a probe main body and its insertion path by detachably providing the insertion path outside the probe without providing the insertion path inside the probe main body. It is an object of the present invention to provide an ultrasonic probe which can be easily cleaned and sterilized.

[0006]

In order to achieve the above object, the present invention relates to an ultrasonic probe comprising a grip portion, an insertion path and an ultrasonic sensor, and a treatment tool detachably attached to the insertion path. Is provided.

[0007]

FIG. 1, FIG. 2 and FIG. 3 show an embodiment of the present invention.
An insertion path 61 and an ultrasonic sensor 62 are connected to a cable 63. In the present invention, as shown in FIG. 3, a semicircular groove 10 is formed on a circumferential side surface of an insertion path portion 61 formed of a metal pipe through which a cable 63 is passed, along the longitudinal direction. The length of the groove 10 is preferably from the tip of the grip portion 60 to the vicinity of the ultrasonic sensor 62. On the other hand, a resin pipe 11 is formed. The diameter of the pipe 11 is slightly larger than the diameter of the groove 10, and the length thereof is formed to be substantially the same as that of the groove 10. When this pipe 11 is attached to the groove 10 of the main body, the pipe 11
The pipe 11 may be fitted into the groove 10 from the circumferential side surface by utilizing its own elasticity. At this time, the groove 10 and the pipe 11 are arranged and formed such that the ultrasonic scanning section axis by the ultrasonic sensor 62 and the center axis of the pipe 11 coincide with each other. If the doctor takes appropriate action while looking at the ultrasound image,
The treatment tool 12 of forceps or a puncture needle is inserted through the pipe 11,
An appropriate treatment is performed by moving the distal end of the treatment tool 12. In addition,
Reference numeral 13 denotes a handle of the treatment tool 12. After the operation, when cleaning and sterilizing the body of the ultrasonic probe, the pipe 1 is inserted through the groove 10.
1, the pipe 11 is discarded, and the main body and its groove 1 are removed.
Wash and sterilize 0.

FIG. 4 is a sectional view similar to FIG. 3 and shows another embodiment of the present invention, in which the cutout 14 of the groove 10 formed in the insertion path 61 is narrowed. Pipe 11
Is made of resin or metal, and its length is
The length is almost the same as the length of 0, and the diameter is smaller than that of the groove 10.
The pipe 11 is inserted into the groove 10 from the grip part 60 side. The treatment tool 12 is passed through the pipe 11. After the operation, the treatment tool 12 and the pipe 11 are removed from the main body,
The body is cleaned and sterilized. In this case, since the groove is provided in the main body, the work becomes easy.

[0009]

The ultrasonic probe for abdominal cavity is provided with a treatment instrument insertion path capable of performing a treatment on an ultrasonic image, whereby there is an effect that the treatment can be performed safely and reliably while checking the ultrasonic image. Further, in this insertion path, a replaceable metal or resin pipe is disposed in the groove on the surface of the insertion tube, so that the main body and the groove can be easily cleaned and sterilized.
