本発明は超音波プローブに着脱自在な超音波プ
ローブ用アプリケータ（単にアプリケータとも称
する）に関する。Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to an ultrasonic probe applicator (also simply referred to as an applicator) that can be attached to and detached from an ultrasonic probe.

面は硬質、かつ、フラツトな面に形成されてい
る。[Technical background of the invention and its problems] Among ultrasound probes, electronic scanning type ultrasonic probes have transducers arranged in a row fixed by backing material, and coated with coating material and acoustic impedance matching on the surface of the transducers. Members and the like are arranged, and the surface that contacts the subject, that is, the ultrasonic wave transmission and reception surface, is formed into a hard and flat surface.

因する凹凸がある場合、超音波プローブの送受波

検体への伝搬効率が非常に悪くなるおそれがあ
る。 Therefore, if there are irregularities on the body surface of the subject due to the presence of bones, etc., the wave transmitting/receiving surface of the ultrasound probe cannot be brought into close contact with the subject, and the propagation efficiency of ultrasound to the subject becomes extremely low. may become worse.
また、開腹手術中に臓器等の超音波像を得るた

述した一般の超音波プローブ同様その送受波面が
硬質、かつ、フラツトな面に形成されているため
に、臓器等に直接接触させるのは非常に危険であ
る。 Furthermore, in order to obtain ultrasound images of organs, etc. during laparotomy, a small intraoperative micro ultrasound probe is sometimes used, but like the general ultrasound probe mentioned above, this small ultrasound probe also has a transmitting and receiving wave surface. Since it is formed on a hard and flat surface, it is extremely dangerous to bring it into direct contact with organs, etc.
そこで従来は、超音波プローブの送受波面と被
検体との間に所謂水袋を介在させる方法が取られ
ていた。 Conventionally, therefore, a method has been adopted in which a so-called water bag is interposed between the wave transmitting/receiving surface of the ultrasonic probe and the subject.

かつた。 However, since the water bag is attached to the ultrasonic probe using a snap lock or the like, there is a problem in that the attachment is complicated. Particularly in the case of small ultrasonic probes for use during micro-surgery, there is a problem in that the attachment of a water bag hinders miniaturization for intra-surgical use and reduces operability. Further, the water bag requires deaerated water, and there are also problems such as the risk of water leakage due to damage to the water bag. Further, although specific embodiments for use during micro-surgery (finger type) have been considered, a locking method for the linear type has not been disclosed.

Another object of the present invention is to provide an applicator for an ultrasonic probe that does not reduce the operability of the ultrasonic probe and is free from water leakage accidents due to damage or the like.

As shown in Fig. 2d, the side shape of this case is U-shaped, slightly expanding from the bottom to the top, and a protrusion 3f is formed in the middle of the side wall 3c. A connecting locking portion 31 is formed at the top of 3f, and a connecting engaging portion 30 is formed at the bottom.
This case is constructed so that it can be divided and connected at the center via the above-mentioned connecting parts.

When an external force is applied to the connecting locking piece 31 on the side surface of the case to release the lock, the case can be separated. At this time, since the connecting engagement portion 30 on the bottom surface can be rotated, the case 3 is opened so that the upper part thereof is expanded. In this way, with the upper part of the case open, the acoustic medium 2 is first placed so that the lower narrow part 2b of the acoustic medium 2 is inserted into the rectangular opening 3d. Thereafter, the probe 1 is placed on the acoustic medium, and the case 3 is returned to its original assembled state. Then,
Two pairs of bent locking pieces 3a, 3a at the upper end of the case are locked so as to cover both shoulders 1b of the probe 1, respectively. When the side connection locking portion 31 is locked, the applicator can be reliably attached to the probe.

ば極めて容易に取り外せる。 After completing a predetermined probe operation, when removing a contaminated acoustic medium for cleaning or disinfecting, apply external force to the connected state of both the side connecting portion 31 and the bottom connecting portion 30 of the case 3. This can be easily done by canceling it. Usually the acoustic medium is soft;
Adhesiveness to other members The acoustic medium used in the present invention has elasticity that is flexibly solidified, so it is difficult to remove it if it has a general indivisible structure. If it has a structure that can be divided, it can be removed extremely easily.
