Abstract
Description
Procedure Simulator
[0001] The present disclosure relates to a procedure simulator.
[0002] As part of minimally invasive endovascular treatment, a procedure of inserting a catheter into a blood vessel is widely performed. There are several methods for inserting a catheter into a blood vessel, depending on the insertion site of the catheter. In many cases, a procedure of inserting a catheter through the radial artery (radial artery approach) is selected. International Publication No. 2015 / 146273 discloses a procedure simulator for practicing the radial artery approach.
[0003] International Publication No. 2015 / 146273
[0004] Another method for inserting a catheter into a blood vessel is the femoral artery approach, which involves inserting a catheter through the femoral artery. While the radial artery approach described above is widely used in catheter treatment, the femoral artery approach may also be selected depending on the patient's condition. However, some physicians have little experience with the femoral artery approach. For this reason, a procedural simulator that allows for effective training and learning of the femoral artery approach is desired.
[0005] The present disclosure aims to solve the above-mentioned problems.
[0006] (1) An aspect of the present disclosure is a procedure simulator for training in the insertion of a medical device into a femoral artery of a human body, the procedure simulator comprising: a human body model simulating a part of the human body including an area through which the left and right femoral arteries run; the human body model having an anatomical model portion constituting one of the left and right sides of the human body model; and a puncture model portion constituting the other of the left and right sides of the human body model; the anatomical model portion having an artery model portion simulating the appearance of the femoral artery on one of the left and right sides of the human body; and a venous model portion simulating the appearance of the femoral vein on one of the left and right sides of the human body; and the puncture model portion having an arterial tube simulating the femoral artery on the other of the left and right sides of the human body;
[0007] With this configuration, the trainee can practice determining the correct puncture position by looking at the anatomical model and referring to the position of the arterial model part corresponding to the femoral artery on one side, imagining the position of the arterial tube corresponding to the other femoral artery on the other side. Furthermore, since the puncture can be performed while checking the position of the arterial tube under ultrasound guidance, the trainee can efficiently train the puncture technique in a highly realistic environment.
[0008] (2) In the procedure simulator described in the above item (1), the anatomical model unit may include a pelvis model unit that simulates the pelvis of the human body.
[0009] With this configuration, the target position for puncturing the arterial tube can be determined while viewing the relative positions of the pelvic model and the artery model, allowing for more efficient learning of the procedure for inserting a medical device into the human body.
[0010] (3) In the procedure simulator described in the above item (2), the anatomical model portion may include a femur model portion that simulates a femur of the human body.
[0011] With this configuration, the puncture target position for the arterial tube can be determined while viewing the positional relationship between the pelvis model and the artery model, as well as the positional relationship between the femur model and the artery model, which allows for more efficient learning of the puncture procedure for the medical device into the human body.
[0012] (4) In the procedure simulator described in the above item (2) or (3), the anatomical model portion may include a ligament model portion that simulates the inguinal ligament of the human body.
[0013] With this configuration, the puncture target position of the medical device can be determined with reference to the position of the ligament model (inguinal ligament), allowing effective learning on how to determine the puncture position.
[0014] (5) In the procedure simulator described in the above item (4), the ligament model portion may be supported by the pelvis model portion.
[0015] With this configuration, the pelvis model also serves as a support for the ligament model, eliminating the need to provide a separate, dedicated support, thereby streamlining the structure.
[0016] (6) In the procedure simulator described in any one of items (1) to (5) above, the puncture model section may have a model main body section that holds the puncture block, and an arterial tube holding section that holds a portion of the arterial tube that protrudes from the model main body section may be provided at an end of the arterial model section that faces the central part of the human body, and a venous tube holding section that holds a portion of the venous tube that protrudes from the model main body section may be provided at an end of the venous model section that faces the central part of the human body.
[0017] With this configuration, the arterial tube and venous tube protruding from the puncture model portion can be effectively supported.
[0018] (7) In the procedure simulator according to any one of the above items (1) to (6), the puncture model portion may have a support base that supports the arterial tube and the venous tube from below.
[0019] With this configuration, when the medical device is inserted into the arterial tube, the arterial tube can be prevented from being displaced too far downward.
[0020] (8) The procedure simulator according to any one of the above items (1) to (7) may further include a pump that supplies simulated blood to the arterial tube and causes pulsation in the arterial tube.
[0021] With this configuration, the pulsation of the arterial tube can be confirmed under echo guidance, thereby improving the realism.
[0022] (9) The procedure simulator according to any one of the above items (1) to (8) may further include a base plate that supports the anatomical model portion and the puncture model portion.
[0023] With this configuration, the human body model can be handled as a whole, making it convenient to carry around.
[0024] (10) In the procedure simulator described in the above item (9), the base plate may have a through-hole formed below the puncture block.
[0025] With this configuration, simulated blood leaking from the arterial tube due to puncture by the medical device can be discharged below the base plate through the through-hole, thereby eliminating or simplifying the process of wiping off the simulated blood on the base plate.
[0026] The procedure simulator of the present disclosure allows trainees to practice determining the correct puncture position in the femoral artery approach. Furthermore, because the trainee can perform the puncture while checking the arterial tube under ultrasound guidance, the trainee can efficiently train the puncture procedure in a highly realistic environment.
[0027] Fig. 1 is a plan view of a procedure simulator according to an embodiment of the present invention, Fig. 2 is a perspective view of a human body model, and Fig. 3 is an exploded perspective view of the human body model.
[0028] A procedure simulator 10 according to this embodiment shown in Fig. 1 is used for training and learning about puncturing a human femoral artery with a medical device 100. The medical device 100 used for puncturing is a hollow puncture needle 101. The medical device 100 may also be a sheath introducer for introducing a catheter into a blood vessel.
[0029] The procedure simulator 10 includes a human body model 12, a base plate 14, and a fluid supply unit 16. The human body model 12 is a simulation of a portion of the human body that includes the region through which the left and right femoral arteries run. Specifically, the human body model 12 visually represents the anatomical structure and appearance of the lower abdomen and surrounding areas of the human body. The human body model 12 includes an anatomical model unit 18 and a puncture model unit 20. In the following description, "left and right" of the human body model 12 refer to the left and right of the human body. Therefore, the left and right of the human body model 12 are opposite to the left and right in FIG. 1 . In the following description, "upper" means vertically upward, and "lower" means vertically downward.
[0030] The anatomical model section 18 constitutes one of the left and right sides of the human body model 12. The puncture model section 20 constitutes the other of the left and right sides of the human body model 12. In this embodiment, the left half of the human body model 12 constitutes the anatomical model section 18, and the right half of the human body model 12 constitutes the puncture model section 20. Alternatively, the right half of the human body model 12 may constitute the anatomical model section 18, and the left half of the human body model 12 may constitute the puncture model section 20.
[0031] As shown in Figure 2, the anatomical model portion 18 has a bone model portion 22, a ligament model portion 24, an artery model portion 26, and a vein model portion 28. The bone model portion 22 has a pelvis model portion 30 and a femur model portion 32. The pelvis model portion 30 is a portion that simulates the pelvis of a human body (the left pelvis in this embodiment). The femur model portion 32 is a portion that simulates the upper part of the femur of a human body (the left femur in this embodiment). The pelvis model portion 30 and the femur model portion 32 are integrally formed.
[0032] Ligament model portion 24 is a portion that simulates the inguinal ligament of a human body. Ligament model portion 24 is supported by pelvis model portion 30. Specifically, one longitudinal end of ligament model portion 24 is supported by ilium portion 301, which corresponds to the ilium of pelvis model portion 30. The other longitudinal end of ligament model portion 24 is supported by pubic portion 302 of pelvis model portion 30. Note that in an actual human body, the inguinal ligament is not directly supported by the pelvis.
[0033] The artery model 26 simulates the appearance of the femoral artery on one side of the human body (the left femoral artery in this embodiment). Therefore, the artery model 26 does not have a straight shape, but rather has a three-dimensional curved shape similar to the femoral artery of a standard human body.
[0034] The vein model 28 simulates the appearance of the femoral vein on one side of the human body (the left femoral vein in this embodiment). Therefore, the vein model 28 has a three-dimensional curved shape similar to the femoral vein of a standard human body. The artery model 26 and the vein model 28 straddle above the pubic region 302 of the pelvis model 30.
[0035] The artery model portion 26 and the vein model portion 28 are preferably colored differently so that they can be easily distinguished from each other. The artery model portion 26 is preferably colored, for example, red so that it is easy to see that it is simulating an artery. The vein model portion 28 is preferably colored, for example, blue so that it is easy to see that it is simulating a vein.
[0036] The artery model portion 26 and the vein model portion 28 are inserted between the pubic bone portion 302 and the ligament model portion 24. The artery model portion 26 and the vein model portion 28 are made of, for example, a hard resin material. The artery model portion 26 and the vein model portion 28 may also be made of a soft material (elastomer material, etc.).
[0037] As shown in FIG. 3 , the puncture model portion 20 has a model main body portion 34, an arterial tube 36, a venous tube 38, and a puncture block 40. The model main body portion 34 simulates the appearance of the right lower abdomen, right groin, and right thigh of a human body. The model main body portion 34 is an opaque member. The model main body portion 34 is colored to resemble human skin. The model main body portion 34 is formed from a hard resin member (e.g., polystyrene, ABS, etc.). The model main body portion 34 is connected to the bone model portion 22 (pelvis model portion 30) of the anatomical model portion 18.
[0038] Model main body 34 has block housing 42 and tube housing groove 44. Block housing 42 is a hole that penetrates model main body 34 in the vertical direction. Block housing 42 is an opening for housing puncture block 40. The shape of block housing 42 viewed vertically may be rectangular as in this embodiment, or may be another shape (e.g., elliptical). In model main body 34, a pair of recesses 421 is formed on each of the left and right sides of block housing 42. A user's fingers can be inserted into the pair of recesses 421 when removing puncture block 40 from block housing 42.
[0039] As shown in FIG. 2 , the tube accommodating groove 44 is a groove for accommodating the arterial tube 36 and the venous tube 38. In this embodiment, the tube accommodating groove 44 has a first groove 441, a second groove 442, and a third groove 443. The first groove 441 is a groove that extends from the block accommodating portion 42 in a direction corresponding to the central side of the human body. One end of the first groove 441 opens on the inner surface of the block accommodating portion 42. The other end of the first groove 441 opens on a portion of the outer surface of the model main body 34 (the central-side end surface 341). The first groove 441 accommodates a portion of each of the arterial tube 36 and the venous tube 38 (portions closer to the central side than the block accommodating portion 42).
[0040] The second groove 442 is a groove that extends from the block housing portion 42 in a direction corresponding to the peripheral side of the human body. One end of the second groove 442 opens on the inner surface of the block housing portion 42. The other end of the second groove 442 opens on another part of the outer surface of the model main body 34 (the end surface 342 on the peripheral side). The second groove 442 accommodates another part of the arterial tube 36 (the part on the peripheral side of the block housing portion 42).
[0041] The third groove 443 is a groove that extends from the block housing portion 42 in a direction corresponding to the peripheral side of the human body. One end of the third groove 443 opens on the inner surface of the block housing portion 42. The other end of the third groove 443 opens on the peripheral side end face 342 of the model main body 34. The third groove 443 houses another part of the venous tubing 38 (the part closer to the peripheral side than the block housing portion 42).
[0042] The model main body 34 further has other grooves 344 and 345. The other grooves 344 and 345 are grooves for accommodating a side branch tube (a tube corresponding to a side branch) branching from the arterial tube 36 when the side branch tube is connected to the arterial tube 36. Note that if no side branch tube is provided as in this embodiment, the other grooves 344 and 345 do not need to be provided.
[0043] The arterial tube 36 is a simulated blood vessel corresponding to the femoral artery on the other side of the human body (the right femoral artery in this embodiment). The arterial tube 36 is made of a soft material. The arterial tube 36 is made of an elastic material such as silicone resin, urethane elastomer, or natural rubber. This allows the arterial tube 36 to be punctured with the puncture needle 101 (see FIG. 1 ). To facilitate visual distinction under ultrasound guidance, the arterial tube 36 preferably has a smaller diameter than the venous tube 38.
[0044] One end (central side) of the arterial tube 36 protrudes from the first groove 441 to the outside of the model main body 34. The other end (peripheral side) of the arterial tube 36 protrudes from the second groove 442 to the outside of the model main body 34. An arterial tube holding part 48 is provided at the end of the arterial model part 26 on the central side of the human body. The arterial tube holding part 48 holds the part of the arterial tube 36 protruding from the model main body 34 from below. The arterial tube holding part 48 has a holding groove 481 that opens upward. The arterial tube 36 is held by the arterial tube holding part 48 by inserting the arterial tube 36 into the holding groove 481.
[0045] The venous tube 38 is a simulated blood vessel corresponding to the femoral vein on the other side of the human body (the right femoral vein in this embodiment). The venous tube 38 is made of a soft material. The venous tube 38 is made of an elastic material such as silicone resin, urethane elastomer, or natural rubber. The venous tube 38 may be made of a different material from the arterial tube 36, and it is preferable to select a material that is more easily crushed than the arterial tube 36 when external pressure is applied. This allows for more accurate reproduction of blood vessel images under ultrasound guidance.
[0046] One end (central side) of the venous tube 38 protrudes from the first groove 441 to the outside of the model main body 34. The other end (peripheral side) of the venous tube 38 protrudes from the third groove 443 to the outside of the model main body 34. A venous tube holding unit 50 is provided at the end of the venous model 28 on the central side of the human body. The venous tube holding unit 50 holds the portion of the venous tube 38 that protrudes from the model main body 34. The venous tube holding unit 50 has a holding groove 501 that opens upward. The venous tube 38 is held in the venous tube holding unit 50 by being inserted into the holding groove 501.
[0047] The puncture block 40 is a component for simulating biological tissue from the epidermis to the muscle layer of a human body. The puncture block 40 is colored to resemble human skin (for example, the same or a similar color as the model main body 34). The puncture block 40 covers the arterial tube 36 and the venous tube 38 from above. The puncture block 40 is supported by the model main body 34 by being inserted into the block housing portion 42 of the model main body 34.
[0048] 3, the puncture block 40 is formed with an arterial tube insertion hole 52 and a venous tube insertion hole 54. The arterial tube 36 is inserted through the arterial tube insertion hole 52. The venous tube 38 is inserted through the venous tube insertion hole 54. The arterial tube 36 and the venous tube 38 are inserted through the puncture block 40 in shapes that follow the course of blood vessels in the human body.
[0049] The puncturing block 40 includes a portion corresponding to human skin. The upper surface of the puncturing block 40 corresponds to human skin. The puncturing block 40 is made of a soft material. The puncturing block 40 is made of an elastic material such as silicone resin, urethane elastomer, or natural rubber. This allows the puncturing block 40 to be punctured by the puncturing needle 101 (see FIG. 1 ).
[0050] A difference in hardness may be provided between the puncture block 40 and the arterial tube 36 so that the user (trainee) can get the sensation of the puncture needle 101 (see FIG. 1 ) piercing the arterial tube 36. For example, assuming a blood vessel suffering from arteriosclerosis, the puncture block 40 may be made relatively soft and the arterial tube 36 may be made relatively hard.
[0051] The puncture model unit 20 further includes a support base 56. The support base 56 supports the arterial tube 36 and the venous tube 38 from below. The support base 56 is formed of a hard resin member (e.g., polystyrene, ABS, etc.). Therefore, the support base 56 is made of a harder material than the puncture block 40. Note that, because the arterial tube 36 and the venous tube 38 are inserted into the puncture block 40, they do not come into direct contact with the support base 56. In other words, the support base 56 supports the arterial tube 36 and the venous tube 38 via the puncture block 40. A recess 41 is formed in the lower part of the puncture block 40. The support base 56 is inserted into the recess 41. The support base 56 is shaped so that its height from below increases toward the central part.
[0052] 2 , the base plate 14 is a member for supporting the anatomical model portion 18 and the puncture model portion 20. The bone model portion 22 of the anatomical model portion 18 is fixed to the upper surface of the base plate 14 via a plurality of supports 58. The artery model portion 26 and the vein model portion 28 are fixed to the upper surface of the base plate 14 via a plurality of supports 60. The model main body portion 34 of the puncture model portion 20 is fixed to the upper surface of the base plate 14.
[0053] Base plate 14 has through-hole 62 formed at least below (directly below) puncturing block 40. Hereinafter, through-hole 62 will also be referred to as "first through-hole 62." First through-hole 62 penetrates base plate 14 in the thickness direction. As shown in FIG. 1 , first through-hole 62 is larger than puncturing block 40 and block housing portion 42 when viewed in the vertical direction.
[0054] As shown in FIG. 2 , the base plate 14 further has a through-hole 64 formed at least below (directly below) the other end of the first groove 441 (the end that opens at the end face 341 on the central side of the model main body 34). Hereinafter, the through-hole 64 will also be referred to as the "second through-hole 64." The second through-hole 64 penetrates the base plate 14 in the thickness direction and serves to allow simulated blood leaking along the first groove 441 to escape below the base plate 14. Note that the first through-hole 62 and the second through-hole 64 may be connected to each other to form a single through-hole.
[0055] 1 , the fluid supply unit 16 includes a first tube 66, a second tube 68, and a pump 70. The first tube 66 is a tube for sending simulated blood from the pump 70 to the arterial tube 36. The first tube 66 is connected to the central end of the arterial tube 36 via a first connector 72. The second tube 68 is a tube for sending simulated blood from the arterial tube 36 to the pump 70. The second tube 68 is connected to the peripheral end of the arterial tube 36 via a second connector 74.
[0056] The pump 70 supplies simulated blood to the arterial tube 36. The pump 70 operates to generate pulsation in the arterial tube 36. Specifically, the pump 70 operates to repeatedly start and stop pumping, thereby generating pressure fluctuations in the arterial tube 36 and generating pulsation in the arterial tube 36. The first tube 66 and the second tube 68 are connected to the pump 70. The pump 70, the first tube 66, the arterial tube 36, and the second tube 68 form a fluid circuit for flowing simulated blood.
[0057] The procedure simulator 10 configured as described above is used as follows.
[0058] The procedure simulator 10 is set up for use as shown in FIG. 1 . The arterial tube 36 and the venous tube 38 are inserted into the puncture block 40. The puncture block 40 is then inserted into the block housing 42 of the model main body 34. At this time, the arterial tube 36 and the venous tube 38 are inserted into the tube housing grooves 44 (first groove 441, second groove 442, and third groove 443). The venous tube 38 is filled with water using an injector 76 (e.g., a syringe). The end of the venous tube 38 opposite the end connected to the injector 76 is blocked with an appropriate blocking device 78 (e.g., forceps). After filling the venous tube 38 with water, the injector 76 may remain connected, or it may be removed and blocked with a blocking device. An absorbent sheet 80 is placed under the base plate 14. The absorbent sheet 80 absorbs any leaked simulated blood.
[0059] A pump 70 is connected to the arterial tube 36 via a first tube 66 and a second tube 68. The pump 70 is filled with simulated blood. The simulated blood is, for example, red-colored water. When the power to the pump 70 is turned on, the pump 70 operates. The operation of the pump 70 supplies the simulated blood to the arterial tube 36 via the first tube 66. The simulated blood that has passed through the arterial tube 36 is returned to the pump 70 via the second tube 68. The pump 70 generates a pulsation in the arterial tube 36 by repeatedly starting and stopping the supply of blood.
[0060] A trainee uses the procedure simulator 10 to practice a puncture procedure using the femoral artery approach. The trainee first presses an echo probe against the puncture block 40 of the puncture model section 20 and determines the puncture target position of the puncture needle 101 under echo guidance. At this time, the trainee can determine the puncture target position by referring to the position of the artery model section 26 of the anatomical model section 18. That is, since the left and right femoral arteries are typically arranged symmetrically in the human body, the trainee can practice determining the puncture target position in the arterial tube 36 to be punctured by referring to the artery model section 26. Note that, because the arterial tube 36 is pulsating, the trainee can also simulate a pulse by touching the surface (top surface) of the puncture block 40.
[0061] In the femoral artery approach, a preferred puncture position for the femoral artery is a site on the femoral artery slightly distal to the inguinal ligament (near the femoral head). By visually confirming the relative positions of the ligament model 24, the femur model 32, and the arterial tube 36, the trainee can visualize the appropriate puncture position for the arterial tube 36. After determining the puncture position, the trainee then inserts the puncture needle 101 into the puncture block 40 and the arterial tube 36 under ultrasound guidance. In an actual femoral artery approach, a guidewire is typically inserted into the femoral artery via the puncture needle 101, and after the puncture needle 101 is removed, a diagnostic or therapeutic catheter is inserted into the femoral artery. Therefore, the insertion procedures for the guidewire and catheter may also be performed during training using the procedure simulator 10. The trainee may also perform training with the anatomical model 18 hidden by a drape. The procedure simulator 10 includes the puncture model section 20 and the anatomical model section 18 on the other side, eliminating the need to refer to separate books or materials when evaluating or reviewing procedures. This makes the procedure simulator 10 highly useful as an educational tool.
[0062] A trainee can also train in hemostatic procedures using the procedure simulator 10 and a hemostatic device (not shown). An example of a hemostatic device is one that seals a hole in a blood vessel by sandwiching the blood vessel between an anchor inserted into the blood vessel and a collagen sponge placed on the outside of the blood vessel. Because such a hemostatic device can be inserted into the puncture block 40 and the arterial tube 36 of the procedure simulator 10, efficient training in hemostatic procedures is possible.
[0063] This embodiment has the following advantages.
[0064] The procedure simulator 10 includes an anatomical model section 18 having an artery model section 26 and a vein model section 28, and a puncture model section 20 having a puncture block 40, an arterial tube 36, and a venous tube 38. With this configuration, a trainee can practice determining the correct puncture position in a femoral artery approach by looking at the anatomical model section 18 and using the position of the artery model section 26 corresponding to one of the left and right femoral arteries as a reference, and imagining the position of the arterial tube 36 corresponding to the other of the left and right femoral arteries. Furthermore, because the puncture can be performed while checking the arterial tube 36 under ultrasound guidance, the puncture procedure can be efficiently trained in a highly realistic environment.
[0065] The anatomical model unit 18 has a pelvis model unit 30 that simulates a pelvis. With this configuration, the puncture target position for the arterial tube 36 can be determined while viewing the positional relationship between the pelvis model unit 30 and the artery model unit 26, allowing for more efficient learning of the puncture technique for inserting the puncture needle 101 into the human body.
[0066] The anatomical model 18 has a femur model 32 that simulates a femur. With this configuration, the puncture target position for the arterial tube 36 can be determined while observing not only the positional relationship between the pelvis model 30 and the artery model 26, but also the positional relationship between the femur model 32 and the artery model 26. This allows for more efficient learning of the puncture technique for inserting the puncture needle 101 into the human body.
[0067] The anatomical model unit 18 has a ligament model unit 24 that simulates the inguinal ligament. With this configuration, the puncture target position of the medical device 100 can be determined with reference to the position of the ligament model unit 24 (inguinal ligament), allowing effective learning of how to determine the puncture position.
[0068] The ligament model part 24 is supported by the pelvis model part 30. With this configuration, the pelvis model part 30 also serves as a support part for the ligament model part 24, so there is no need to provide a separate dedicated support part, thereby streamlining the structure.
[0069] An arterial tube holding part 48 is provided at the end of the arterial model part 26 on the central side of the human body, and a venous tube holding part 50 is provided at the end of the venous model part 28 on the central side of the human body. With this configuration, the arterial tube 36 and the venous tube 38 protruding from the puncture model part 20 can be effectively supported.
[0070] 3, the puncture model unit 20 has a support base 56 that supports the arterial tube 36 and the venous tube 38 from below. With this configuration, when the medical device 100 is inserted into the arterial tube 36, the arterial tube 36 can be prevented from being displaced too far downward.
[0071] The procedure simulator 10 includes a pump 70 that supplies simulated blood to the arterial tube 36. The pump 70 generates pulsation in the arterial tube 36. With this configuration, the pulsation of the arterial tube 36 can be confirmed under echo guidance, thereby improving realism.
[0072] The human body model 12 includes a base plate 14 that supports the anatomical model portion 18 and the puncture model portion 20. With this configuration, the human body model 12 can be handled as a whole, making it convenient to carry around.
[0073] The base plate 14 has a first through-hole 62 formed below the puncturing block 40. With this configuration, simulated blood leaking from the arterial tube 36 due to the puncture and removal of the puncture needle 101 can be discharged below the base plate 14 (to the absorbent sheet 80; see FIG. 1 ) through the first through-hole 62. This eliminates or simplifies the process of wiping off the simulated blood on the base plate 14. The base plate 14 also has a second through-hole 64, so that simulated blood that has dropped from the first groove 441 can be discharged below the base plate 14 (to the absorbent sheet 80; see FIG. 1 ) through the second through-hole 64.
