Description

  Embodiments of the present invention relate to a grasper of an ultrasonic probe and an ultrasonic probe.

  BACKGROUND In recent years, when testing a subject, a modality may be used which collects internal information of the subject and images the inside of the subject based on the collected information to generate a medical image. As this modality, for example, an ultrasound diagnostic imaging apparatus can be mentioned. The ultrasound diagnostic imaging apparatus receives a reflection signal of ultrasound transmitted from an ultrasound probe toward a region to be diagnosed, and generates an ultrasound image on the region to be diagnosed.

  As an ultrasonic probe, for example, there is an ultrasonic probe of a type in which an ultrasonic radiation surface is used in contact with the skin of a subject. In addition, for example, there is also an ultrasonic probe which uses an ultrasonic radiation surface in direct contact with the target organ during surgery. By using such an ultrasonic probe, for example, it becomes possible to identify a site to be ablated.

  In the case of using an ultrasonic probe in which the ultrasonic radiation surface is in direct contact with the target organ during such a surgery, for example, the operator directly grips and operates the ultrasonic probe.

  In the case of the ultrasonic probe of the form which an operator directly grips, there exist several shapes in the shape of a holding part. For example, it is a type in which the imaging cross section and the gripped part are orthogonal to each other, or the type in which the imaging cross section and the gripped part are parallel. However, in any case, the portion to be gripped by the ultrasonic probe needs to have a certain size so that the operator can grip.

  In addition, an ultrasonic wave is configured such that a pinched portion is provided on the surface opposite to the ultrasonic radiation surface, and the pinched portion is pinched by a forceps so that the ultrasonic probe can be grasped and operated. There is also a probe. For example, an ultrasonic probe that holds the held portion with a forceps is used as follows.

  That is, an ultrasonic probe and forceps are inserted into a body cavity through a trocar disposed in a body wall of a subject. The ultrasound probe and the forceps are inserted from different trocars, respectively. The operator operates the ultrasonic probe inserted into the body cavity by grasping the held portion with forceps. In addition, when a plurality of held portions are provided, the operator can hold the held portions to be held to the held portions at other positions. Thus, the operator can easily move the position of the ultrasonic probe and manipulate the angle in a limited space such as a body cavity.

  In the case of an ultrasound probe operated using such a forceps, the size of the ultrasound probe itself can be reduced because the operator does not have to directly grip the ultrasound probe. On the other hand, it is necessary to have a structure (held part) for holding the ultrasonic probe with a forceps.

  As described above, although there are multiple ultrasonic probe forms in the ultrasonic probe that brings the ultrasonic radiation surface into direct contact with the target organ during surgery, it is difficult to make these shapes common due to its structure is there. Therefore, the operator needs to have a dedicated ultrasonic probe also in order to cope with various techniques.

  In addition, since the ultrasonic probe directly contacts the ultrasonic radiation surface with the organ, it is necessary to attach a sheath (probe cover) to the ultrasonic probe to prevent infection. However, particularly in the case of an ultrasonic probe in which the forceps are used by gripping the held portion, the held portion may possibly break the sheath covering the ultrasonic probe.

  Furthermore, when attaching and using a sheath on an ultrasonic probe, when unnecessary air bubbles mix in the inside of a sheath, it is possible that the said air bubble moves between a sheath and an ultrasonic probe. And if the said bubble moves to an ultrasonic radiation | emission surface, since air does not pass an ultrasonic wave, possibility that imaging may become impossible by the presence of the said bubble is also considered.

  The present invention has been made to solve the above-mentioned problems, and the object of the present invention is to be used both in a method performed directly by an operator by hand and a method performed by an operator by grasping using forceps. An object of the present invention is to provide a grasper and an ultrasonic probe of an ultrasonic probe which is possible and does not reveal the disadvantages due to the use of a sheath.

  The grasping tool of the ultrasonic probe in the embodiment is inserted into the abdominal cavity of the subject via a trocar, and an ultrasonic transducer for transmitting and receiving ultrasonic waves, and an ultrasonic radiation surface provided with an ultrasonic transducer. Is mounted on an ultrasonic probe provided with a clamp-held grasped portion provided on the opposite side. Moreover, the holding | gripping tool of an ultrasonic probe is a 1st attachment provided with a bottom face, a plane, and an accommodating part. The bottom surface contacts the opposite surface of the ultrasound probe. The plane is opposite to the bottom surface and is grasped by the operator. The accommodating portion accommodates the pinched portion between the bottom surface and the flat surface. The distance between the bottom surface and the flat surface of the first attachment is formed such that the distance at the other end in the long side direction is shorter than the distance at the one end in the long side direction.

[Configuration of first attachment]
FIG. 1 is a perspective view showing the entire first attachment 1 constituting the grasping tool of the ultrasonic probe and the entire ultrasonic probe P to which the first attachment is attached. FIG. 2 is a side view of the first attachment 1. The first attachment 1 is attached to an ultrasonic probe P provided with a pinched portion for pinching a forceps (not shown).

  The ultrasound diagnostic imaging apparatus includes an ultrasound probe P that transmits and receives (transmits and receives) ultrasound to and from an object, and an apparatus main body to which the ultrasound probe P is detachably connected. However, in FIG. 1, the illustration of the apparatus main body and the entire ultrasonic diagnostic apparatus is omitted. A signal line Ps whose illustration is omitted in the middle of the ultrasonic probe P shown in FIG. 1 is connected to an apparatus main body (not shown).

  Here, the ultrasound diagnostic imaging apparatus is an example of a medical diagnostic imaging apparatus capable of noninvasively examining the internal structure of the subject, the blood flow state, and the like. The ultrasound diagnostic imaging apparatus transmits ultrasound from an ultrasound probe P provided with a transducer (piezoelectric transducer) toward a region to be examined of a subject. Then, the transducer of the ultrasonic probe P receives the reflected wave generated by the mismatch of the acoustic impedance inside the object. An ultrasound image is generated based on the received signal obtained in this manner.

  The ultrasonic probe P transmits an ultrasonic wave into the subject by each ultrasonic transducer to scan a scan region, and receives a reflected wave from the subject as a reflection signal. As this scan, for example, there are various scans such as a B mode scan and a Doppler mode scan. The ultrasonic probe 2 is compatible with sector scanning, linear scanning, convex scanning, etc., and is arbitrarily selected according to the diagnosis site.

  The ultrasound probe P in the embodiment of the present invention is used by being inserted into the abdominal cavity of a subject via a trocar. The ultrasonic probe P includes an ultrasonic transducer P1 that transmits and receives ultrasonic waves, and a held portion P2. The ultrasonic transducer P1 is formed on a so-called bottom surface, for example, when the surface on which the held portion P2 is provided is defined as a flat surface. Therefore, in the perspective view shown in FIG. 1, the ultrasonic transducer P1 can not be directly seen. Therefore, in FIG. 1, the ultrasonic transducer P <b> 1 is indicated by a dashed-dotted line. An ultrasonic wave is transmitted from the ultrasonic transducer P1 formed on the bottom surface. In the following, of the bottom surface, in particular, a region (surface) where the ultrasonic transducer P1 is formed is referred to as “ultrasonic emission surface Pa”. Moreover, illustration of the acoustic lens is omitted here for convenience of illustration.

  The ultrasonic radiation surface Pa is actually formed so as to slightly protrude outward of the ultrasonic probe P. As shown in FIG. In this regard, for example, as shown in FIG. 4 described later, in the drawings, the protruding state is exaggeratedly shown from the viewpoint of easy viewing. Further, as described above, in FIG. 1 and FIG. 4 to be described later, although the acoustic lens is not shown, an acoustic lens is actually provided. Therefore, in fact, the ultrasonic radiation surface Pa in FIG. 4 and the like also has a curved shape provided in the acoustic lens.

  Moreover, the said to-be-held part P2 is provided in the surface Pb on the opposite side to the ultrasonic wave radiation surface Pa in which the ultrasonic transducer | vibrator P1 is provided. The held portion P2 is a portion held by the forceps when the ultrasonic probe P is inserted into the abdominal cavity of the subject. In the embodiment of the present invention, one held portion P2 is provided on the surface Pb on the opposite side. However, a plurality of held portions P2 may be provided on the ultrasonic probe P.

  The to-be-held part P2 is formed in the shape of a rectangular parallelepiped head, and is provided with a support that connects the head and the opposite surface Pb. Here, it is cut in parallel with the surface connecting the opposite surface Pb and the ultrasonic radiation surface Pa, and the cross section thereof is formed to be substantially T-shaped. However, although the supported portion P2 in the embodiment of the present invention is formed in such a shape, it is not limited to such a shape, and it may be a shape that allows a forceps to grip the supported portion P2. For example, any shape may be adopted.

  The first attachment 1 includes a bottom surface 1a, a flat surface 1b, and a housing portion 1c. The bottom surface 1a is in contact with the opposite surface Pb of the ultrasonic probe P. The flat surface 1 b is an opposite surface of the bottom surface 1 a and is a surface gripped by the operator. When the first attachment 1 is attached to the ultrasonic probe P, the accommodation portion 1c accommodates the held portion P2 between the bottom surface 1a and the flat surface 1b.

  As described above, since the housing portion 1 c adopts a structure in which the held portion P 2 is housed between the bottom surface 1 a and the flat surface 1 b, the housing portion 1 c is indicated by a broken line in FIG. Further, the housing portion 1c is formed in a size such that the held portion P2 housed when the first attachment 1 is attached to the ultrasonic probe P does not move in the housing portion 1c. .

  Also, the first attachment 1 adopts a substantially streamlined shape. That is, the distance between the bottom surface 1a and the plane 1b is formed such that the distance at the other end in the long side direction is shorter than the distance at the one end in the long side direction. Specifically, as shown in FIG. 1 or FIG. 2, when the end where the accommodation portion 1c is formed is one end and the end in the long side direction is the other end, The flat surface 1b is a gentle slope toward the other end while maintaining the same distance between the bottom surface 1a and the flat surface 1b from one end to the middle of the long side, and finally the flat surface 1b is connected to the bottom surface 1a .

  The reason why the first attachment 1 adopts such a shape is that, as described later, when using the ultrasonic probe P to which the first attachment 1 is attached, these should be covered with a sheath However, this is for making it difficult for air bubbles to enter the sheath even when the sheath is attached or during use of the ultrasonic probe P. Moreover, there is also a viewpoint which improves the operativity at the time of an operator mounting | wearing the 1st attachment 1 and operating the ultrasound probe P. FIG.

  Furthermore, in the first attachment 1, a first fitting portion 1d is provided on both side surfaces connecting the bottom surface 1a and the flat surface 1b. The first fitting portion 1 d is formed to be a recess on the side surface. The first fitting portion 1d is used to mount a second attachment 2 or the like described later. In the first attachment 1 shown in FIG. 1, two pairs of first fitting portions 1 d are provided two on each side surface. Any number of first fitting portions 1d may be provided as long as they are provided in pairs on both side surfaces.

  As described above, two pairs of the first fitting portions 1d shown in FIG. 1 are provided on each side surface. However, the first fitting portion 1d may not be provided at the positions separated on the side surface on one side as described above. That is, one concave portion may be formed along the long side of the first attachment 1 so as to connect the two first fitting portions 1 d provided on the side surface on one side. By forming the first fitting portion 1 d in this manner, when the second attachment 2 is attached to the first attachment 1, the attachment position of the second attachment 2 can be freely set. it can.

  In the side view of the first attachment 1 shown in FIG. 2, two first fitting portions 1d are shown. Moreover, the accommodating part 1c is shown with the broken line. In the first attachment 1, the bottom surface 1a is brought into contact with the opposite surface Pb of the ultrasonic probe P, and the signal line Ps is provided from the front of the ultrasonic probe P without the signal line Ps. The ultrasonic probe P is mounted by sliding toward the The to-be-held part P2 intrudes into the accommodating part 1c, and is accommodated. Therefore, the housing portion 1 c is provided at one end of the first attachment 1.

  FIG. 3 is a cross-sectional view of the first attachment 1 shown in FIG. 2 taken along the line A-A. The housing portion 1c is provided between the bottom surface 1a and the flat surface 1b. Further, when the first attachment 1 is attached to the ultrasonic probe P, a part of the housing portion 1c is opened at the bottom surface 1a so that the support of the held portion P2 passes. Furthermore, it is also shown that the first fitting portions 1d are formed so as to be concave portions, two on each side surface.

  FIG. 4 is an overall view showing the first attachment 1 attached to the ultrasonic probe P. As shown in FIG. The operator uses the ultrasonic probe P, to which the first attachment 1 is attached, with the palm pointing to or in contact with the plane 1 b of the first attachment 1. When the first attachment 1 is attached to the ultrasonic probe P, the bottom surface 1a of the first attachment 1 comes in contact with the opposite surface Pb of the ultrasonic probe P. Further, the held portion P2 of the ultrasonic probe P is housed in the housing portion 1c.

  FIG. 5 is a cross-sectional view taken along line B-B of the overall view of the first attachment 1 shown in FIG. 4 attached to the ultrasonic probe P. As shown in FIG. Since the line B-B in FIG. 4 is provided just at one end of the first attachment 1, only the signal line Ps is cut and drawn. Therefore, the first fitting portion 1 d is indicated by a broken line. Moreover, the state in which the to-be-held part P2 is accommodated in the accommodating part 1c is shown.

  FIG. 6 is an overall view showing a state in which the first attachment 1 is attached to the ultrasonic probe P and the sheath S is covered. When the ultrasound probe P is used in the abdominal cavity of a subject, as described above, the entire sheath of the ultrasound probe P is covered to prevent infection. In FIG. 6, the first attachment 1 and the ultrasonic probe P are covered by the sheath S. The end of the sheath S is fixed at the portion of the signal line Ps. The inside of the sheath S is in close contact with the first attachment 1 and the ultrasonic probe P. By covering with the sheath S in this manner, air bubbles can be prevented from entering the inside of the sheath S. Further, since the first attachment 1 and the ultrasonic probe P are covered by the sheath S, the first attachment 1 and the ultrasonic probe P can be reused by replacing the sheath S.

  FIG. 7 is an overall view showing a state in which the sheath S is covered only on the ultrasonic probe P and the first attachment 1 is attached to the ultrasonic probe P. FIG. 7 differs from the case shown in FIG. 6 in that only the ultrasound probe P is covered with the sheath S. In this case, since the first attachment 1 is not covered by the sheath S, although the ultrasonic probe P can be reused, reuse of the first attachment 1 is not planned.

  FIG. 8 shows the whole of the first modification of the attachment (first attachment 1A) constituting the grasping tool of the ultrasonic probe and the modification of the ultrasound probe on which the first attachment 1A is mounted (ultrasonic probe PA) is a perspective view showing the whole. In the following, the same components as those of the first attachment 1 are denoted by the same reference numerals, and the description of the same components is omitted because it is redundant. In the following description, the first attachment 1 and the first attachment 1A will be collectively referred to as "first attachment 1" as appropriate.

  The ultrasonic probe PA is formed such that the short side of the opposite surface 1b is longer than the short side of the ultrasonic radiation surface 1a. That is, as shown in FIG. 8, the ultrasonic probe PA has a substantially inverted trapezoidal shape as if drawn from the opposite surface Pb to the ultrasonic radiation surface 1 a. The ultrasonic transducer P1 is provided on the ultrasonic radiation surface 1a, and the held portion P2 is provided on the opposite surface Pb, as in the ultrasonic probe P shown in FIG.

  The first attachment 1A, which is a variation attached to such an ultrasonic probe PA, has a substantially rectangular parallelepiped shape. Unlike the first attachment 1, the first attachment 1A, which is a modification, brings the bottom surface 1a and the opposite surface Pb of the ultrasonic probe P into contact with each other to contact the ultrasonic probe P with the first attachment 1. It is not to wear. That is, the first attachment 1A is formed to cover the side surface of the ultrasonic probe PA formed by connecting the long side of the ultrasonic radiation surface 1a of the ultrasonic probe PA and the long side of the opposite surface 1b. And only the ultrasonic radiation surface 1a is open.

  In addition, the first fitting portion 1d used to mount the second attachment 2 and the accommodation portion 1c for accommodating the pinched portion P2 of the ultrasonic probe PA is provided. Neither the attachment 1 nor the first attachment 1A is changed.

  Since the ultrasonic probe PA and the first attachment 1A adopt such a configuration, when the first attachment 1A is attached to the ultrasonic probe PA and used by the operator, the operator For example, unlike the case shown in FIG. 4, only the first attachment 1A is gripped to operate the ultrasonic probe PA.

[Configuration of second attachment]
Next, the second attachment will be described. FIG. 9 is a perspective view showing the whole of the second attachment 2 that constitutes the grasping tool of the ultrasonic probe P. As shown in FIG. FIG. 10 is a plan view showing a state in which the second attachment 2 is attached to the first attachment 1. FIG. 11 is a cross-sectional view taken along line C-C of the plan view showing the state in which the second attachment 2 shown in FIG. 10 is attached to the first attachment 1.

  The second attachment 2 is a holding tool of the ultrasonic probe P attached to the first attachment 1 and used. By utilizing the second attachment 2, it is possible to make the portion to be held orthogonal to the first attachment 1 (the imaging cross section of the ultrasonic probe P).

  The second attachment 2 includes a mounting portion 2a having a second fitting portion 2c for mounting on the first attachment 1, and a gripping portion 2b that is gripped by the operator when using the second attachment 2 Have.

  The mounting portion 2 a includes a second fitting portion 2 c for fitting to the first fitting portion 1 d of the first attachment 1. One pair of first fitting portions 1d are provided on both side surfaces of the first attachment 1 (one pair of first fitting portions 1d shown in FIG. 1) so that they become concave portions. It is formed. The second fitting portion 2c is formed in a convex shape, and can be fitted to the first fitting portion 1d.

  When the second fitting portion 2c is fitted to the first fitting portion 1d, the wall portion 2d in which the second fitting portion 2c is formed is opposed to the side surface of the first attachment 1, It will be in the state of contact. That is, the wall 2 d of the second attachment 2 sandwiches the side surface of the first attachment 1.

  In the plan view of FIG. 10, the second attachment 2 is attached to the first attachment 1 so that the long side of the second attachment 2 is orthogonal to the long side of the first attachment 1. Is shown. That is, when the second fitting portion 2c is fitted to the first fitting portion 1d, the long side direction of the first attachment 1 and the short side direction of the second attachment 2 become parallel. Provided in At this time, the second fitting portion 2c is fitted to the first fitting portion 1d. This state is shown by a broken line in FIG.

  On the other hand, FIG. 11 is a cross-sectional view taken along the line C-C of FIG. 10, so that the fitting state is clearly shown. As described above, since the second attachment 2 is attached to the first attachment 1, the operator can operate the ultrasonic probe P freely by holding the holding portion 2 b.

  For example, as shown in FIGS. 1 and 10, the first attachment 1 is provided with a total of two pairs of first fitting portions 1d on both side surfaces thereof. Therefore, for example, when a phenomenon occurs in which the ultrasonic probe P can not be moved properly by contacting the body inner wall portion of the open subject, the operator appropriately selects two pairs of first fitting portions 1d. The second attachment 2 can be attached by selecting one of the two.

  FIG. 12 is a cross-sectional view showing a first modified example (second attachment 2A) of the second attachment 2 shown in FIG. In the following, the same components as those of the second attachment 2 are denoted by the same reference numerals, and the description of the same components is omitted because it is redundant.

  In the second attachment 2, the second attachment 2 is attached to the first attachment 1 by fitting the second fitting portion 2 c to the first fitting portion 1 d of the first attachment 1. .

  On the other hand, in the second attachment 2A, the second fitting portion 2c is formed to be able to be fitted to the fitting portion Pc provided to the ultrasonic probe P. That is, in the second attachment 2A, instead of being attached to the first attachment 1, the first attachment 1 is attached to the ultrasonic probe P while being held in the attachment portion 2a.

  Thus, the second attachment 2A is directly attached to the ultrasonic probe P. Therefore, since the second attachment 2 is firmly attached to the ultrasonic probe P, when the operator uses the ultrasonic probe P, there is a gap between the first attachment 1 and the ultrasonic probe P. Can be avoided.

  Next, a second modification of the second attachment 2 will be described using FIGS. 13 to 14. FIG. 13 is a perspective view showing a second modification (second attachment 2B) of the second attachment 2. As shown in FIG. FIG. 14 is a plan view of the second attachment 2B. Furthermore, FIG. 15 is a cross-sectional view showing a state in which the second attachment 2B, which is the second modification, is attached to the first attachment 1 and the ultrasonic probe P. In the following, the same components as those of the second attachment 2 are denoted by the same reference numerals, and the description of the same components is omitted because it is redundant.

  The second attachment 2B shown in FIG. 13 is shown upside down in order to clearly show its shape. That is, when attached to the first attachment 1, the bottom surface 2 f in contact with the flat surface 1 b of the first attachment 1 is visible, and is a surface opposite to the bottom surface 2 f and is a surface grasped by the operator Is not visible in FIG.

  A third fitting portion 2h is formed on the bottom surface 2f side of the second attachment 2B. That is, the third fitting portion 2h is provided on the wall portion 2i which is formed by extending from the bottom surface 2f and covers the plane 1b to the first fitting portion 1d in the first attachment 1.

  In the second attachment 2B shown in FIG. 13, two pairs of third fitting portions 2h are formed one by one at opposing positions of the wall portion 2i. These third fitting portions 2 h are fitted to the first fitting portion 1 d of the first attachment 1. The state in which the second attachment 2B is attached to the first attachment 1 is as shown in FIG. 14 and FIG.

  That is, the two pairs of third fitting portions 2h of the second attachment 2B are fitted to the two pairs of first fitting portions 1d formed in the first attachment 1, respectively. The third fitting portion 2h is formed along the long side direction of the wall portion 2i of the second attachment 2B.

  Therefore, when the second attachment 2B is attached to the first attachment 1, the bottom surface 2f contacts the flat surface 1b of the first attachment 1, and the two side surfaces connecting the bottom surface 1a and the flat surface 1b The wall 2i of the attachment 2B faces and contacts. Then, as shown in FIG. 14, the long side direction of the first attachment 1 and the long side direction of the second attachment 2B are parallel to each other.

  A recess 2j is formed between the bottom surface 2f and the flat surface 2g of the second attachment 2B and along the long side direction of the second attachment 2B. The recesses 2 j are respectively formed on both side surfaces connecting the bottom surface 2 f and the flat surface 2 g. By forming the recess 2 j, the operator can hook a finger in the recess 2 j, so that the second attachment 2 B and the ultrasonic probe P can be grasped better.

  Next, a third modified example of the second attachment 2 will be described with reference to FIGS. FIG. 16 is a cross-sectional view showing a state in which the second attachment 2C, which is the third modification, is attached to the first attachment 1 and the ultrasonic probe P. As shown in FIG. FIG. 17 is a plan view showing a usage example of the second attachment 2C. In the following, the same components as those of the second attachment 2 are denoted by the same reference numerals, and the description of the same components is omitted because it is redundant.

  In the second attachment 2C according to the third modification, a storage unit in which the operator can insert a finger between the bottom surface 2f and the plane 2g of the second attachment 2B according to the second modification 2 l are formed.

  That is, as shown in the cross-sectional view of FIG. 16, the storage portion 21 is formed between the bottom surface 2f and the flat surface 2g and between the depressions 2j and 2j so that the finger of the operator can be inserted. . When operating the ultrasonic probe P, the operator inserts the finger F of the second attachment 2C attached to the first attachment 1 and operates it, as shown in FIG. be able to.

  As described above, if the ultrasonic probe P can be operated by inserting the finger F, an operation method increases in addition to gripping and operating the depression 2j of the second attachment 2C by hand. Therefore, the operator can select an appropriate gripping method of the ultrasonic probe P in accordance with the region to be inspected when performing an inspection using ultrasonic waves.

  In addition, the storage part 21 shown to FIG. 16, FIG. 17 is not formed so that the 2nd attachment 2C may be penetrated. Therefore, in this case, the finger F can be inserted only from the direction in which the opening is provided.

  However, not only such a shape, for example, the storage portion 21 can be formed so as to penetrate the second attachment 2C in the long side direction. If the storage unit 21 is formed to penetrate the second attachment 2C, the finger F can be inserted from any side, and the selectable operation method is further increased.

  As shown in FIG. 6 and FIG. 7, even if the sheath S is attached to the ultrasonic probe P and / or the first attachment 1, the sheaths 2 to 2 C described above are sheaths. I can not wear the S. Therefore, it is not planned to reuse the second attachments 2 to 2C.

[Other ways of using the first attachment]
Up to this point, the grasping tool of the ultrasonic probe P has been described above by taking an example in which the second attachments 2 to 2C are attached to the first attachment 1. In each case, by fitting each fitting portion provided in the second attachments 2 to 2 C to the first fitting portion 1 d provided in the first attachment 1, the second attachment 1 d is attached to the first attachment 1. Attachment 2 to 2C.

  On the other hand, it is possible to mount other adapters using the 1st fitting part 1d concerned. Hereinafter, description will be made with reference to FIGS. 18 to 21 as an example. FIG. 18 is a plan view showing a state in which the puncture adapter 3 is attached to the first attachment 1. FIG. 19 is a side view showing the first attachment 1 to which the puncture adapter 3 is attached.

  When an ultrasound image is generated using the ultrasound probe P, the operator may observe the obtained ultrasound image, and a puncture operation may be performed on the treatment target site depicted in the ultrasound image. is there. That is, by inserting the puncture needle toward the treatment target site of the subject by this puncturing, the tissue of the treatment target site is collected, the drug is injected to the treatment target site, or a heating element for heating is used. It can be inserted and treated.

  The puncture adapter 3 has conventionally been used for such a puncture technique.
