Description

[Technical Field]

[0001] The present invention relates to a compression hemostatic attachment that is attached to an ultrasonic probe and used, and an ultrasonic hemostatic monitoring system that uses the same. [Background technology]

[0002] Intravascular treatments such as cerebrovascular treatment and cardiology treatment have been widely performed. In these types of treatment procedures, the first step is to insert an instrument into the blood vessel, and the final step is always to remove the instrument from the blood vessel and stop the bleeding.

[0003] Manual compression, which relies on human power, is a common method of hemostasis in intravascular treatment, but recently, alternative devices to manual compression hemostasis, such as hemostatic pressure devices, have been used (see, for example, Patent Documents 1 to 3). Also, hemostatic devices using collagen or sutures, such as collagen-based absorbable local hemostatic materials, non-absorbable suture sets, and absorbable local hemostatic agents, are sometimes used. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-57386 [Patent Document 2] Japanese Patent Application Publication No. 7-178104 [Patent Document 3] Japanese Patent Application Publication No. 8-71077 Summary of the Invention [Problem to be solved by the invention]

[0005] The conventional hemostatic methods described above have the following problems. For example, when performing hemostasis using manual compression or a hemostatic pressure device, it is necessary to determine the appropriate pressure required for hemostasis and apply that pressure continuously. However, pressure application relies heavily on sensation, making it extremely difficult to objectively and accurately determine the appropriate pressure. Therefore, there is a problem that mastery of the technique is necessary to achieve stable hemostasis. Another problem is that manual compression can be very tiring for the surgeon. Furthermore, because clotting factors and other factors contribute to hemostasis, a certain amount of blood flow within the blood vessels is necessary. Therefore, excessive pressure will prevent complete hemostasis. On the other hand, if the applied pressure is too weak, blood will leak out of the blood vessels, resulting in the formation of a hematoma.

[0006] The present invention has been made in consideration of the above-mentioned problems, and its object is to provide an ultrasonic hemostasis monitoring system that can easily grasp an appropriate compressive pressure and can continuously apply the appropriate compressive pressure without relying on human power. Another object of the present invention is to provide a compressive hemostasis attachment that is suitable for use in the above-mentioned excellent ultrasonic hemostasis monitoring system.

[0019] An ultrasonic hemostasis monitoring system according to an embodiment of the present invention will now be described in detail with reference to FIGS.

[0020] As shown in FIG. 1, an ultrasonic hemostasis monitoring system 11 of this embodiment is composed of an ultrasonic diagnostic device 21, a support device 31, and a pressure hemostasis attachment 41.

[0021] The pressure hemostatic attachment 41 is a device attached to the ultrasonic probe 22, and is used with a portion of it in contact with the body S1 when stopping bleeding. The pressure hemostatic attachment 41 includes a plate-shaped base material 46, an ultrasonically transparent member 51, a wall portion 56 as an adapter portion, and a rod-shaped member 61 as a connected portion.

[0022] As shown in Figures 2 and 3, the base material 46 is a flat plate-shaped base material having a first surface 46a that contacts the body and a second surface 46b on the opposite side, and constitutes the main portion of the compression hemostatic attachment 41. The base material 46 is formed using a material with a certain degree of rigidity, such as a rigid resin material that does not have flexibility. A base material 46 made of a rigid resin material prevents the compression hemostatic attachment 41 from bending even when it is pressed against the body S1 during hemostasis, thereby efficiently applying compression pressure and reliably achieving hemostasis. Furthermore, the resin material used for the base material 46 is preferably a heat-resistant resin, which allows for sterilization at high temperatures and allows the compression hemostatic attachment 41 to be reused. There are no particular limitations on the resin material as long as it is heat-resistant, but examples that can be used include polypropylene (PP) resin, polyvinylidene chloride (PVDC) resin, polyamide (PA) resin, polycarbonate (PC) resin, polyphenylene sulfide (PPS) resin, polyimide (PI) resin, polyetherimide (PEI) resin, polysulfone (PSF) resin, fluororesin, polyamideimide (PAI) resin, and phenol (PF) resin.

[0023] The dimensions and shape of the base material 46 are not particularly limited, but for example, a base material 46 having a thickness of approximately 2 mm to 10 mm and a side length of approximately 50 mm to 150 mm and a rectangular shape in plan view is used. The thickness within this range is chosen because it provides the compression hemostatic attachment 41 with suitable weight and rigidity. The length within this range is chosen because it provides the area necessary for hemostasis and is easy for the surgeon to grasp and handle. In particular, in this embodiment, a base material 46 having a thickness of 5 mm, a long side length of 100 mm, and a short side length of 70 mm and a rectangular shape in plan view is selected. The four corners of this base material 46 are rounded and chamfered to prevent pain when they come into contact with the patient's body S1.

[0024] A through-hole 48 is formed in the center of the base material 46, corresponding to the location where the ultrasound-transmitting window 47 will be formed. The through-hole 48 is determined based on the shape and dimensions of the ultrasound emitting surface 24 of the ultrasound probe 22 used in the ultrasound hemostasis monitoring system 11. For example, if the ultrasound emitting surface 24 is rectangular in plan view, measuring 20 mm x 50 mm, the through-hole 48 will be formed with approximately the same shape and dimensions.

[0025] A flat ultrasonically-transmitting member 51 is bonded and fixed to the entire first surface 46a side of the base material 46 using an adhesive or the like. The ultrasonically-transmitting member 51 is a member for forming an ultrasonically-transmitting window 47 that transmits ultrasonic waves in the thickness direction of the base material 46 and blocks the through-holes 48 from the first surface 46a side. The ultrasonically-transmitting member 51 is formed using a resin material that transmits ultrasonic waves more easily than the resin material forming the base material 46. The ultrasonically-transmitting member 51 is formed thinner than the base material 46 to facilitate the transmission of ultrasonic waves. The color of the ultrasonically-transmitting member 51 is not particularly limited, but it is preferably transparent. A transparent member 51 allows the situation directly below the ultrasonically-transmitting member 51 to be visible, making it easier to check for bleeding. In this embodiment, a transparent resin plate made of PS (polystyrene) resin and having a thickness of approximately 1 mm is used as the ultrasonically-transmitting member 51.

[0026] The adapter portion is provided on the second surface 46b side of the base material 46. The adapter portion serves to hold the ultrasonic probe 22 by bringing the ultrasound emitting surface 24 of the ultrasonic probe 22 into contact with the ultrasound-transmitting member 51 from the second surface 46b side. The adapter portion of this embodiment is a wall portion 56 that surrounds the ultrasound-transmitting window 47 over its entire circumference, and this wall portion 56 has a recessed shape with an open top. The wall portion 56 is made of a flexible resin material and is formed to have substantially the same dimensions and shape as the ultrasound-transmitting window 47 and the through-hole 48 in a plan view. The distal end side of the ultrasonic probe 22 is inserted into and held in this recessed wall portion 56. Taking the area of ​​the ultrasound-transmitting window 47 as a reference, the base material 46 preferably has an area approximately two to three times that of the ultrasound-transmitting window 47. This is because, in order to prevent misalignment between the base material 46 and the body S1 and to reliably stop bleeding, it is preferable that the base material 46 has a relatively large area (compression surface).

[0027] The wall portion 56 has a pair of locking portions 58 on the edge of the opening. The pair of locking portions 58 are formed integrally with the wall portion 56 and are arranged opposite each other. The pair of locking portions 58 are formed in the shape of protrusions, and have convex portions 58a that can be engaged with and disengaged from the irregularities 22a on the side surface of the ultrasonic probe 22. Therefore, the pair of locking portions 58 are engaged with the ultrasonic probe 22 from both sides, thereby enabling the ultrasonic probe 22 to be securely held (see FIGS. 3(a) and 3(b)).

[0028] The rod-shaped member 61, which is the connection portion, protrudes from the second surface 42b of the substrate 46 in a direction perpendicular to the substrate 46. This rod-shaped member 61 is a portion that is grasped by the gripping portion 33 of the support device 31 and connected to the support device 31. For example, while it is possible to grasp and hold a portion of the substrate 46, having a dedicated connection portion such as the rod-shaped member 61 has the advantage of providing a stable and reliable hold. Furthermore, this rod-shaped member 61 has a cylindrical shape so that it can be easily grasped by the gripping portion 33 of the support device 31. Furthermore, to prevent the wall portion 56 from getting in the way when the gripping portion 33 grasps, the rod-shaped member 61 is disposed on the outer periphery of the substrate 46 and protrudes more than the wall portion 56.

[0029] As shown in FIG. 1 , an ultrasonic diagnostic device 21 has an ultrasonic probe 22 and a display device 23. The ultrasonic probe 22 has a shape and size that can be held by an operator, and a plurality of ultrasonic transducers (not shown) are arranged in an array inside the tip. In this embodiment, the ultrasonic emitting surface 24 of the ultrasonic probe 22 has a substantially rectangular shape in a plan view. The plurality of ultrasonic transducers are arranged in a row along the longitudinal direction of the ultrasonic emitting surface 24. A cable 25 is provided at the base end of the ultrasonic probe 22, and the tip of the cable 25 is connected to a connection terminal 27 on a device main body 26 of the ultrasonic diagnostic device 21. In this embodiment, an example in which the ultrasonic probe 22 and the device main body 26 are connected by wire has been shown, but a wireless connection may also be used.

[0030] The device main body 26 includes an internal computer (not shown) including a CPU, ROM, RAM, etc., and also includes the display device 23 on its front surface. The display device 23 is not particularly limited, and may be, for example, a color liquid crystal display, a color LED display, or a color plasma display. The computer controls the transmission of ultrasonic waves from the ultrasonic probe 22 and the reception of reflected wave signals from the body S1. The computer also processes the received signals acquired by the ultrasonic probe 22 (i.e., B-mode processing and color Doppler processing) to generate an ultrasonic image in which a color Doppler image is superimposed on a B-mode image, and controls the display device 23 to display the generated image. In other words, this ultrasonic diagnostic device 21 is configured to display, on the display device 23, an ultrasonic image showing the shape of blood vessels and the state of blood flow during compression hemostasis.

[0031] As shown in FIG. 1 , the support device 31 is a support arm device having a multi-joint arm 32 that can be freely moved in the X, Y, and Z directions. The support device 31 is used to prevent the compression hemostatic attachment 41 from shifting from the hemostatic position P1 during compression hemostasis. The arm 32 is a multi-joint arm formed by connecting multiple rods with joints. In this embodiment, a multi-joint arm is used in which all joints can be simultaneously fixed by fixing one point, for example, but this is not limited to this. That is, multi-joint arms with various structures can be used as the support device 31. The arm 32 has a gripping portion 33 at its tip, and its base end is connected and supported to the upper end of a support column 35. A counterweight 34 that balances the weight of the ultrasound probe 22 and the arm 32 itself is connected to the base end of the arm 32. A mounting bracket 36 is attached to the lower end of the support column 35, and the support column 35 is supported and fixed to a fixed object T1 using this mounting bracket 36. The term "fixed object T1" here broadly refers to the floor or wall itself, or any structure placed on or fixed to them. For example, even a movable cart with wheels or other such features can be treated as a fixed object T1 if it has a structure that allows it to be temporarily stopped and fixed.

[0032] Next, a method of using the ultrasonic hemostasis monitoring system 11 configured as described above will be described.

[0033] To use this ultrasonic hemostasis monitoring system 11, the support device 31 is fixed in advance to a fixed object T1, such as a bedside cart or a cart for the ultrasound diagnostic device 21 (see FIG. 1). As shown in FIGS. 3(a) and 3(b), the compression hemostasis attachment 41 is attached to the tip of the ultrasonic probe 22. At this time, a pair of locking portions 58 lock onto the ultrasonic probe 22 from both sides, thereby securely holding the ultrasonic probe 22 to the wall portion 56. A gel-like coupling material (echogel) is applied in advance to the upper surface of the ultrasound-transmitting window 47, which is surrounded by the wall portion 56. This coupling material fills the gap between the convex ultrasound emitting surface 24 and the flat ultrasound-transmitting member 51, enabling ultrasound to be transmitted to the first surface 46a. The presence of the wall portion 56 surrounding the ultrasound-transmitting window 47 completely prevents the coupling material applied to the ultrasound-transmitting window 47 from leaking out and ensures its secure retention.

[0034] Next, as shown in FIGS. 1 and 4 , the first surface 46a of the pressure hemostatic attachment 41, which is holding the probe, is brought into contact with a hemostasis site P1 on the surface of the body S1 (e.g., the brachial artery). The patient places their upper arm on a horizontal support table (not shown). The patient may be in a supine or sitting position. The ultrasound diagnostic device 21 is then activated to display an ultrasound image. The surgeon determines the position of the pressure hemostatic attachment 41 while checking the ultrasound image. Typically, the surgeon adjusts the position of the pressure hemostatic attachment 41 so that the hemostasis site P1 is located directly below the center of the ultrasound-transparent window 47. An ultrasound tomographic image of the blood vessel is displayed on the display device 23 of the ultrasound diagnostic device 21 in FIG. 1 . The area enclosed by a dashed white circle in the blood vessel tomographic image indicates the puncture site requiring hemostasis (i.e., the hemostasis site P1). The surgeon identifies the puncture site by viewing the blood vessel tomographic image and then adjusts the pressure appropriately. Then, after confirming that a certain amount of blood flow is secured in the blood vessel lumen near the puncture site and that blood is not leaking from the puncture site to the outside of the blood vessel, the compression pressure is determined. Once the appropriate hemostasis position and appropriate compression pressure have been determined as described above, the joints of the arms 32 of the support device 31 are fixed to fix the position of the compression hemostasis attachment 41. This reduces the risk of the arms 32 shifting when fixed or shifting over time.

[0035] During the hemostasis procedure, the surgeon can monitor the blood vessel shape and blood flow state in real time using the ultrasound diagnostic device 21 to view ultrasound images of the hemostasis area P1. As long as appropriate hemostasis is maintained, the surgeon generally does not need to operate the compression hemostasis attachment 41. Because the ultrasound image of the hemostasis area P1 is always displayed on the display device 23, if a positional shift occurs due to, for example, body movement, the surgeon can grasp this fact from a location away from the patient. This makes it possible to quickly correct the positional shift and restore appropriate hemostasis.

[0036] Therefore, according to this embodiment, the following effects can be obtained.

[0037] (1) In the compression hemostatic attachment 41 and the ultrasonic hemostasis monitoring system 11 using the same, the ultrasonic probe 22 is held by the wall portion 56, which serves as the adapter, so that the ultrasound emitting surface 24 of the ultrasonic probe 22 is positioned in contact with the ultrasound-transmitting member 51. As a result, ultrasound emitted by the ultrasonic probe 22 passes through the ultrasound-transmitting window 47 and can be emitted to the outside from the first surface 46a, which is the body contact side. Furthermore, by connecting the rod-shaped member 61, which serves as the connecting portion, to the support device 31, the base material 46 is supported by the support device 31. As a result, while the first surface 46a of the base material 46 is brought into contact with the hemostasis site P1 of the body S1 and compression pressure is applied to stop the hemostasis, the base material 46 can be held in place and prevented from shifting from the hemostasis position. At the same time, an appropriate compression pressure can be continuously applied without relying on manual force. This reliably reduces the burden on the surgeon performing the hemostasis. Furthermore, according to this embodiment, the ultrasonic probe 22 receives reflected ultrasonic waves from the hemostasis area P1, and the blood vessel shape and blood flow state during hemostasis are visualized based on the received ultrasound image and displayed on the display device 23. This makes it easy to visually grasp the appropriate compression pressure. In other words, in the past, sufficient experience was required to adjust the degree of compression pressure while ensuring blood flow. In contrast, according to this embodiment, the positioning of the compression hemostasis attachment 41 and the determination of the compression pressure can be performed while checking the ultrasound image. Therefore, even a beginner can reliably perform hemostasis at the same level as an experienced practitioner.

[0038] The embodiment of the present invention is merely an example, and may be modified as appropriate within the scope of the invention.

[0039] In the above embodiment, the wall portion 56 serving as the adapter has a generally rectangular (approximately I-shaped) shape in plan view. However, this is not limiting. For example, the wall portion 56A may be generally cross-shaped in plan view, as in another embodiment of a compression hemostatic attachment 41A shown in FIG. 5 . The wall portion 56B may be generally T-shaped in plan view, as in another embodiment of a compression hemostatic attachment 41B shown in FIG. 6 . The generally cross-shaped shape in plan view allows the attachment direction to be changed by 90°. This allows ultrasound images to be viewed in two orthogonal directions (i.e., parallel and perpendicular to the blood vessel), making it possible to reliably and easily confirm the status of hemostasis. Furthermore, the generally T-shaped shape in plan view allows the attachment of a so-called T-shaped probe, in which ultrasound transducers are arranged in two orthogonal directions. This allows ultrasound images in the short axis direction and the long axis direction to be viewed simultaneously, making it possible to reliably and easily confirm the status of hemostasis.

[0040] In the above embodiment, the ultrasonically transparent member 51 is a transparent resin plate made of PS and bonded to the entire second surface 46b of the base material 46, but this is not limiting. For example, it is of course possible to configure the base material 46 so that this type of transparent resin plate is bonded only to the center of the second surface 46b. Also, in the above embodiment, the base material 46 and the ultrasonically transparent member 51 are formed as separate bodies using different resin materials, but the base material 46 and the ultrasonically transparent member 51 may be integrally formed using the same resin material. In this case, specifically, the portion of the base material 46 that corresponds to the ultrasonically transparent member 51 may be formed relatively thin, and the portions other than the ultrasonically transparent member 51 may be formed relatively thick.

[0041] In the above embodiment, the ultrasound-transmitting member 51 is inseparably attached to the base material 46, but this is not limiting. For example, in another embodiment of a compression hemostatic attachment 41C shown in FIG. 7, a transparent resin sheet material is used as the ultrasound-transmitting member 51A. An adhesive layer 71 that can be attached to and removed from the second surface 46b is formed on one side of the transparent resin sheet material in an area other than the area corresponding to the ultrasound-transmitting window 47. Therefore, during use, the transparent resin sheet material can be fixed to the base material 46 by attaching the adhesive layer 71 side of the transparent resin sheet material to the second surface 46b. After use, this transparent resin sheet material, which is the side that contacts the body, can be peeled off and removed from the base material 46 and replaced with a new one. In other words, with this configuration, the portions of the compression hemostatic attachment 41C other than the transparent resin sheet material can be reused.

[0042] In the above embodiment, the wall portion 56 surrounding the entire ultrasound-transmitting window 47 is used as the structure of the adapter portion, but this is not limited thereto and the adapter portion may be a wall portion that partially surrounds the ultrasound-transmitting window 47. Note that the adapter portion may be structured in a manner other than the wall portion 56. Furthermore, the adapter portion that holds the ultrasonic probe 22 is not limited to one that holds the tip end of the ultrasonic probe 22, and may also hold the side or base end.

[0043] In the above embodiment, the adapter portion has the locking portion 58 that can be engaged with and disengaged from the irregularities 22a on the side surface of the ultrasonic probe 22. However, the locking portion 58 is not an essential component and may be omitted.

[0044] In the above embodiment, a cylindrical rod-shaped member 61 is used as the connection target portion, but this is not limiting. For example, a rectangular rod-shaped member may be used, or a non-rod-shaped member (such as a protruding piece) may be used. In this case, the connection target portion does not have to protrude from the second surface 46b of the base material 46, and may protrude from the side surface of the base material 46, for example.

[0045] In the above embodiment, a support arm device equipped with a counterweight 34 was used as the support device 31, but a support arm device without a counterweight 34 may also be used. Also, in the above embodiment, the base end side of the support device 31 was fixed to the cart, but it may of course be fixed to a fixed object T1 other than the cart. Note that the support device 31 does not necessarily have to be equipped with an arm, and any device may be used as long as it can hold the compression hemostatic attachments 41 to 41C and the ultrasonic probe 22 so that they cannot shift position and can apply a constant compression pressure to the hemostasis area P1.

[0046] In the above embodiment, the present invention has been described as being applied to hemostasis of the brachial artery, but the present invention may also be applied to hemostasis of other parts of the body S1, such as the radial artery in the forearm or the femoral artery in the groin.
