Description

[0001]
The present invention relates to an ultrasonic probe for body cavity that is used with a biopsy adapter.
[0002]
[Prior art]
There is an intracavity probe as an ultrasonic probe using a biopsy adapter. In recent years, the probe for body cavity is used with a balloon covered when the probe for body cavity is used alone for the purpose of preventing infection between patients and safety and health. When using a biopsy adapter, a balloon is put on the probe for body cavity, and then the biopsy adapter is attached for use. After use, incinerate the balloon, disinfect the probe for body cavity and reuse it, and insert the needle into the human body, and sterilize and recycle the biopsy adapter because blood etc. will adhere when extracting the target part. I use it. The balloon is made of natural rubber with a thickness of about 0.1 mm to prevent deterioration of the acoustic characteristics of the probe for body cavity, while the material for the probe for body cavity is not softened at the temperature at the time of disinfection. In addition, heat-resistant engineering plastics are used. The biopsy adapter is made of a material that does not soften at high temperatures during sterilization, for example, heat-resistant engineering plastic or metal.
[0003]
[Problems to be solved by the invention]
This heat-resistant engineering plastic has hard mechanical properties. For this reason, when the biopsy adapter is mated to the mating part by covering the balloon with the probe for body cavity, the biopsy adapter locally compresses and stretches the balloon unless handled carefully. It was sometimes stretched and damaged.
[0004]
An object of the present invention has been made in view of the above problems, than for the body cavity even wearing the biopsy adapter from the top covered with balloon ultrasonic probe for body cavity balloon to prevent damage It is to provide an acoustic probe .
[0005]
[Means for Solving the Problems]
The above purpose is based on information detected by the balloon (3) that covers the probe (1) for body cavity and the probe (1) for body cavity in order to prevent infection and to provide safety and health for the patient. The biopsy adapter (2) serving as a needle guide when the target part of the patient is punctured with a needle to extract the tissue of the living body, and the probe for body cavity after being covered with the balloon (3) An ultrasonic probe for body cavity comprising (1) and a mating portion for mating the biopsy adapter (2), and an adhesive on a side surface of a distal end portion of the body cavity probe (1) The tip of the biopsy adapter (2) is locked so that the inner surface of the tip of the biopsy adapter (2) contacts with the balloon (3) through the balloon (3). A first viscoelastic body (4) having a recess (5) for It is achieved by.
Further, U is provided on the left and right side surfaces of the central portion of the body cavity probe (1), and serves as a positioning guide when the biopsy adapter (2) is engaged with the body cavity probe (1). A second viscoelastic body (6) having a letter-shaped notch (7) and a fixing hole (9) for fixing the biopsy adapter (2) to the intracavity probe (1); To be achieved.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings by taking a body cavity probe using a biopsy adapter as an example. FIG. 1 is a side view showing a state where a balloon is placed on a probe for body cavity according to the present invention and a biopsy adapter is mounted thereon, and FIG. 2 is a cross-sectional view taken along line AA in FIG. Shows a cross-sectional view along the line BB in FIG.
[0007]
In each of the drawings, reference numeral 1 is a body cavity probe for detecting information in the body cavity, and 2 is a biopsy tissue extracted by puncturing the target portion with a needle based on information detected by the body cavity probe. The biopsy adapter 3 serving as a needle guide when performing the operation is a balloon formed of a thin rubber to be put on the body cavity probe 1 during use for prevention of patient infection and safety and health. 4 is a first viscoelastic body made of a material such as rubber bonded to the left and right side surfaces of the distal end portion of the probe 1 for body cavity, and 5 is a first viscoelastic body provided at the distal end portion of the probe 1 for body cavity. Recesses 6 for locking the tip of the biopsy adapter 2 formed on the viscoelastic body 4 are provided on the left and right of the central portion of the probe 1 for body cavity, and are made of a material such as rubber that mates with the biopsy adapter 2. A second viscoelastic body to be formed, 7 is a U-shaped notch that serves as a positioning guide when the biopsy adapter (2) and the body cavity probe (1) are engaged , 8 is an adhesive, Reference numeral 9 denotes a fixing hole for fixing the second viscoelastic body 6 to the body cavity probe 1.
[0008]
Next, a procedure for attaching the balloon 3 and the biopsy adapter 2 to the intracavity probe 1 as shown in FIG. 1 when performing biopsy will be described. First, the balloon 3 is placed over the entire circumference from the tip of the probe 1 beyond the center. Next, the U-shaped notch 7 of the biopsy adapter 2 is inserted into the second viscoelastic body 6 of the intracavity probe 1, and the biopsy adapter 2 is rotated around the second viscoelastic body 6. When the distal end of the biopsy adapter 2 is brought into contact with the recess 5 via the balloon 3, the biopsy adapter 2 is mounted on the body cavity probe 1 from above the balloon 3.
[0009]
Next, the operation of the first viscoelastic body 4 and the second viscoelastic body 6 will be described.
In FIG. 2, when the balloon 3 is placed on the first viscoelastic body 4 fixed with the adhesive 8 on both side surfaces of the distal end of the probe 1 for body cavity, and the biopsy adapter 2 is mounted thereon, The inner surface of the tip of the biopsy adapter 2 comes into contact with the recess 5 of one viscoelastic body 4 through the balloon 3. In this state, even if the tip of the biopsy adapter 2 is slightly tilted or displaced and inserted into the recess 5, the first viscoelastic body 4 is formed of rubber or the like. Therefore, the balloon 3 can be prevented from being broken without receiving a predetermined amount of pressure or stretching force.
[0010]
In FIG. 3, a balloon 3 is placed on the second viscoelastic body 6 fixed to the pair of fixing holes 9 in the center of the probe 1 for body cavity, and the U-shaped cut of the biopsy adapter 2 is placed thereon. The notch 7 is brought into contact. A second viscoelastic body 6 is inserted into the U-shaped notch 7 through the balloon 3. In this state, the balloon 3 is deformed even if the center of the U-shaped cutout 7 is slightly shifted during insertion or the center of the second viscoelastic body 6 is inclined. There is no damage due to no great pressure.
[0011]
In this embodiment, the first viscoelastic body 4 is provided on both side surfaces of the distal end portion of the body cavity probe 1 in the joint portion of the body cavity probe 1, the balloon 3, and the biopsy adapter 2. The second viscoelastic body 6 is fixed to the pair of fixing holes 9 at the center of the body cavity probe 1, and the first viscoelastic body 4 such as rubber and the second viscoelasticity are fixed. An embodiment in which the body 6 is bonded or attached to the biopsy adapter 2 side, or the first viscoelastic body 4 such as rubber and the second viscoelastic body 6 are bonded or inserted into a balloon. Of course, the first viscoelastic body 4 and the second viscoelastic body 6 may be fixed to either the body cavity probe 1, the biopsy adapter 2, or the balloon 3. Shall.
[0012]
【The invention's effect】
According to the present invention, in the body cavity probe using the biopsy adapter, the viscoelastic body is provided at the joint between the balloon and the body cavity probe. The deformation of the elastic body can prevent the balloon from being damaged.
