Description

[Technical field]

[0001] The present invention relates to a surgical training device that is constructed using simulated bone and soft tissue arranged in anatomical positions that mimic a real living body. [Background technology]

[0002] Conventionally, as shown in Patent Document 1, this type of human body model is constructed by acquiring shape and position data of bones, muscles, and skin through image analysis of the human body, and forming simulated bones and simulated muscles based on the acquired data, and forming a mold for making a model of at least a part of the external shape of the human body. Then, a human body model is known in which the simulated bones and simulated muscles are placed inside the mold and the remaining areas are filled with a material for forming simulated skin.

[0003] [Patent Document 1] JP 2017-596997 A Summary of the Invention [Problem to be solved by the invention]

[0004] Although such conventional mannequins are faithful to the structure of the actual human body, they are bulky and inappropriate as training tools primarily intended for bone surgery.

[0005] On the other hand, although simulated bones have long been available as training equipment for bone surgery, even if surgical training is conducted with the bone itself exposed, it is far removed from actual surgery where the field of view is limited by muscles, etc.

[0006] Therefore, the present invention aims to provide a bone surgery training device that uses simulated bones and structures (articular tissues) placed in anatomical positions that can easily and reliably reproduce actual surgery, and a method for manufacturing the same. [Means for solving the problem]

[0007] The bone surgery training device using the simulated bone or joint tissue composed of the simulated bone according to the first invention is as follows: A fat portion that is an elastic plastic body having a color corresponding to adipose tissue and that is attached to a training target portion of the simulated bone; A muscle portion that is arranged to cover the fat portion and is an elastic plastic body having a color corresponding to muscle tissue; A tubular vascular portion corresponding to a blood vessel, the vascular portion being arranged adjacent to the fat portion and the muscle portion; a subcutaneous tissue portion that is an elastic plastic body having a color corresponding to subcutaneous tissue and that is arranged so as to cover the entire part including the muscle portion; a film-like skin portion corresponding to skin, the film-like skin portion being covered so as to cover the surface of the subcutaneous tissue portion; Equipped with The fat portion, the muscle portion, the blood vessel portion, the subcutaneous tissue portion and the skin portion are partially formed in a portion of the simulated bone that is to be trained.

[0008] According to the bone surgery training device using the simulated bone or joint tissue formed from the simulated bone of the first invention, by sequentially arranging elastic plastic bodies having colors corresponding to fat, muscle, and subcutaneous tissue in relation to the simulated bone or joint tissue formed from the simulated bone, it is possible to easily and reliably form biological tissues, etc. that need to be handled during bone or joint surgery in association with the simulated bone or joint tissue.

[0009] In addition, by providing a tubular vascular section that corresponds to blood vessels, it becomes possible to conduct surgical training that takes into account the blood vessels that require caution during bone surgery.

[0010] In addition, by wrapping the fat, muscle, blood vessels, and subcutaneous tissue sections on the simulated bone with a film-like skin section, these can be integrated together and the skin, including its surface, can be reproduced.

[0011] Here, by partially forming the fat, muscle, blood vessel, subcutaneous tissue, and skin areas in the area that is the training target for the simulated bone or the joint tissue composed of the simulated bone, it is possible to realize a simple configuration primarily intended for bone surgery, unlike large-scale human body models.

[0012] On the other hand, the area of ​​the simulated bone or the joint tissue composed of the simulated bone that is the subject of training is provided with skin, subcutaneous tissue, muscle, blood vessels and fat, which correspond to the skin membrane, skin, muscle, blood vessels and fat that the surgeon must take into consideration before reaching the bone or joint during surgery, and therefore these can be treated in the same manner as in an actual surgery, and then training can be performed to expose the area of ​​the simulated bone or the joint tissue composed of the simulated bone that is the subject of training.

[0013] In addition, since each part is designed in a color and arrangement that corresponds to actual biological tissue, the surgeon performing the procedure can train while being aware of which biological tissue is being treated.

[0014] Furthermore, the simulated bone or the joint tissue portion formed by the simulated bone that is the subject of training and exposed by the procedure can also have the surgical field reproduced by muscle areas, just as the field of view is actually limited by muscles, making it possible to simulate surgery such as resection of the simulated bone itself in a manner that is close to actual surgery.

[0015] In this way, the bone surgery training device using the simulated bone or articular tissue composed of the simulated bone of the first invention can reproduce actual surgery easily, reliably and safely as training that does not damage blood vessels etc. and limits crushing of muscle tissue to a minimum.

[0016] The second invention relates to a training instrument for bone surgery using a simulated bone or a joint tissue formed from the simulated bone, which is the first invention, The present invention is characterized in that it further comprises a thread-like nerve portion corresponding to a nerve, which is arranged adjacent to the muscle portion.

[0017] According to the bone surgery training device using the simulated bone or joint tissue composed of the simulated bone of the second invention, by arranging a thread-like nerve part corresponding to the nerve adjacent to the muscle part, it is possible to easily and reliably reproduce the nerve, which is a biological tissue that needs to be dealt with during surgery on bones and joints.

[0018] In this way, the bone surgery training device using the simulated bone or articular tissue composed of the simulated bone of the second invention makes it possible to easily and reliably reproduce actual surgery, including nerves, including training that does not cause nerve damage.

[0019] The third invention relates to a training instrument for bone surgery using a simulated bone or a joint tissue formed from a simulated bone, which is the first invention, The artificial bone or the artificial bone-constituted joint tissue is characterized in that it further comprises either or both of a resin ligament portion equivalent to a ligament and a fiber bundle tendon tissue portion equivalent to tendon tissue, arranged adjacent to the artificial bone or the artificial bone-constituted joint tissue.

[0020] According to the bone surgery training device of the third invention using a simulated bone or joint tissue formed from a simulated bone, by arranging either or both of a resin ligament portion equivalent to a ligament and a fiber bundle tendon tissue portion equivalent to tendon tissue adjacent to the simulated bone or joint tissue formed from the simulated bone, it is possible to easily and reliably reproduce ligaments and tendons, which are biological tissues that need to be dealt with during bone and joint surgery.

[0021] In this way, the bone surgery training device using the simulated bone or articular tissue composed of the simulated bone of the third invention makes it possible to easily and reliably reproduce actual surgery, including ligaments and tendons, including training that does not cause damage to the ligaments and tendons.

[0022] The fourth aspect of the present invention provides a training instrument for bone surgery using a simulated bone or a joint tissue formed from the simulated bone, comprising any one of the first to third aspects of the present invention, The blood vessel portion is filled with a liquid that resembles blood.

[0023] According to the fourth invention of the bone surgery training device using a simulated bone or joint tissue composed of a simulated bone, by inserting a liquid resembling blood (e.g., a red liquid) into the blood vessel portion, it is possible to easily and reliably reproduce the texture of blood vessels and the situation when blood vessels are damaged in the same way as in actual surgery.

[0024] In this way, according to the bone surgery training device using the simulated bone or articular tissue composed of the simulated bone of the fourth invention, blood vessels that need to be taken into consideration during actual surgery can be reproduced in a more realistic, simple and reliable manner.

[0025] The manufacturing method of the simulated bone or the surgical training instrument for joint tissues composed of the simulated bone according to the fifth invention is as follows: A target part determination step of determining a part to be a training target of the simulated bone; a fat portion attachment step of attaching a fat portion, which is an elastic plastic body having a color corresponding to adipose tissue, to the part to be trained determined by the target part determination step; a muscle portion arrangement step of arranging a muscle portion which has a color corresponding to muscle tissue and is an elastic plastic body so as to cover the fat portion applied in the fat portion application step; a blood vessel portion arranging step of arranging a tubular blood vessel portion corresponding to a blood vessel adjacent to the fat portion affixed in the fat portion affixing step and the muscle portion arranged in the muscle portion arranging step; a subcutaneous tissue portion arrangement step of covering the site with a subcutaneous tissue portion that has a color corresponding to subcutaneous tissue and is an elastic plastic body so as to cover the entire site including the muscle portion arranged in the muscle portion arrangement step; a skin portion forming step of covering the surface of the subcutaneous tissue portion, the entire site of which has been covered by the subcutaneous tissue portion arranging step, with a film-like skin portion corresponding to skin; Equipped with The fat portion applied in the fat portion application step, the muscle portion arranged in the muscle portion arrangement step, the blood vessel portion arranged in the blood vessel portion arrangement step, the subcutaneous tissue portion arranged in the subcutaneous tissue portion arrangement step, and the skin portion covered in the skin portion formation step are partially formed in the area that is to be the training target of the simulated bone determined in the target area determination step.

[0026] According to the manufacturing method of the fifth invention for a bone surgery training device using a simulated bone or joint tissue composed of a simulated bone, elastic plastic bodies having colors corresponding to fat, muscle, and subcutaneous tissue are sequentially arranged on the simulated bone, whereby biological tissues that need to be dealt with during bone or joint surgery can be easily and reliably formed in association with the simulated bone or joint tissue.

[0027] In addition, by providing a tubular vascular section that corresponds to blood vessels, it becomes possible to conduct surgical training that takes into account the blood vessels that require caution during bone surgery.

[0028] In addition, by wrapping the fat, blood vessels, muscle, and subcutaneous tissue sections on the simulated bone with a film-like skin section, these can be integrated together and the skin, including its surface, can be reproduced.

[0029] Here, by partially forming the fat, muscle, blood vessel, subcutaneous tissue, and skin areas in the area that is the training target for the simulated bone or the joint tissue composed of the simulated bone, it is possible to realize a simple configuration primarily intended for bone surgery, unlike large-scale human body models.

[0030] On the other hand, the area of ​​the simulated bone that is the subject of training includes skin, subcutaneous tissue, muscle, blood vessels, and fat, which correspond to the skin membrane, skin, muscle, blood vessels, and fat that the surgeon must take into consideration before reaching the bone or joint during surgery, so these can be treated in the same way as in an actual surgery, and then training can be performed to expose the area of ​​the simulated bone and joint tissue that is the subject of training.

[0031] In addition, since each part is designed in a color and arrangement that corresponds to actual biological tissue, the surgeon performing the procedure can train while being aware of which biological tissue is being treated.

[0032] Furthermore, the areas of the simulated bones and joint tissues that are the subject of training and exposed by the procedure can be made to reproduce the surgical field by muscle areas, just as the field of view is actually limited by muscles, making it possible to simulate surgeries such as resection of the simulated bones and joint tissues in a manner that is close to actual surgeries.

[0033] In this way, according to the manufacturing method of the fifth aspect of the present invention for a training instrument for bone surgery using a simulated bone or a joint tissue constituted by a simulated bone, an actual surgery can be reproduced simply and reliably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0035] As shown in FIG. 1, in this embodiment, the manufacturing method of a bone surgery training instrument using a simulated bone 1 includes a target area determination step (STEP 10), a fat portion attachment step (STEP 11), a muscle portion placement step (STEP 12), a blood vessel portion placement step (STEP 13), a subcutaneous tissue portion placement step (STEP 14), and a skin portion formation step (STEP 15).

[0036] 2A, the simulated bone 1 is supported on a base 2 by a plurality of support rods 3, 4, and 5. The support rods 3 to 5 and the simulated bone 1 are supported with the insertion parts 3A to 5A at the tips of the support rods 3 to 5 inserted into through holes provided in the simulated bone 1, and may be more firmly fixed by appropriately screwing wing nuts (not shown) onto threads cut into the insertion parts 3A to 5A.

[0037] First, in the target site determination step (STEP 10), a site to be a target for bone surgery training is determined for the simulated bone 1 shown in Fig. 2A. For example, the case where the femoral condyle is set as the target T will be described below.

[0038] Next, in the fat attachment step (STEP 11), as shown in FIG. 2B, fat 11, which is an elastic plastic body (viscous body) having a color corresponding to fat, is attached to the femoral condyle that was designated as the target T in the target area determination step (STEP 10).

[0039] The elastic plastic body (viscous body) having a color corresponding to fat is composed of, for example, yellow clay (wood powder clay) corresponding to fat, and this yellow clay is applied evenly around the femoral condyle of the target T as the fat portion 11.

[0040] Next, in the muscle portion placement step (STEP 12), as shown in Figure 3A, a muscle portion 12, which is an elastic plastic body (viscous body) having a color corresponding to muscle, is placed on the target T of the simulated bone 1 to which the fat portion 11 has been attached in the fat portion attachment step (STEP 11), so as to cover the fat portion 11.

[0041] The elastic plastic body (viscous body) having a color corresponding to muscle is composed of, for example, red clay (wood powder clay) corresponding to muscle, and this red clay is placed as muscle portion 12 (here, multiple muscle portions 12A, 12B corresponding to the quadriceps) so as to cover fat portion 11 of the femoral condyle of target T.

[0042] Next, in the blood vessel portion placement step (STEP 13), as shown in Figure 3B, a tubular blood vessel portion 13 corresponding to a blood vessel is placed adjacent to the fat portion 11 attached in the fat portion attachment step (STEP 11) and the muscle portion 12 placed in the muscle portion placement step (STEP 12).

[0043] The vascular portion 13 is simply constituted by a straw, and such vascular portion 13 (here, the femoral artery passing under the femur) is placed adjacent to the fat portion 11 and muscle portion 12 below the femoral condyle of the target T.

[0044] In addition, a red liquid resembling blood may be passed through the tubular blood vessel portion 13 by using a pump (not shown) or a balloon filled with red liquid.

[0045] Next, in the subcutaneous tissue portion placement step (STEP 14), as shown in FIG. 4A, the entire target T, including the muscle portion 12 placed in the muscle portion placement step (STEP 12), is covered with a subcutaneous tissue portion which is an elastic plastic body (viscous body) having a color corresponding to skin.

[0046] The elastic plastic body (viscous body) having a color corresponding to skin is composed, for example, of clay (wood powder clay) of a flesh-color that corresponds to skin, and this flesh-colored clay is used as the subcutaneous tissue portion 14 to cover the entire muscle portion 12 (including the blood vessel portion 13) of the femoral condyle of the target T so as to be hidden.

[0047] Next, in the skin portion forming step (STEP 15), as shown in FIG. 4B, the surface of the subcutaneous tissue portion 14 that has covered the entire target T in the subcutaneous tissue portion arranging step (STEP 14) is covered with a film-like skin portion 15 that corresponds to a skin membrane.

[0048] The film corresponding to the skin membrane is made of, for example, transparent or semi-transparent polyvinylidene chloride (PVDC), and the film is used as the skin portion 15 to cover the entire subcutaneous tissue portion 14 multiple times to form the skin portion.

[0049] In the skin portion forming step (STEP 15), it is preferable to appropriately remove the simulated bone 1 that has been formed up to the subcutaneous tissue portion 14 from the support rods 3 to 5, and form the skin portion 15 by rotating either the film or the simulated bone 1, and fix the simulated bone 1 with the skin portion 15 formed thereon to the support rods 3 to 5 in order to adhere the skin portion 15 to the subcutaneous tissue portion 14.

[0050] A method of using the bone surgery training device using the simulated bone 1 constructed as above will be described.

[0051] First, as shown in Figure 5, the trainee can use a scalpel to incise the skin portion 15 and subcutaneous tissue portion 14 of the target T, which correspond to the dermal membrane and skin, so as to approach the target area of ​​the femur, just as in an actual femur surgery.

[0052] From this state, the surgeon approaches the target area of ​​the femur while spreading apart the target area X using surgical instruments such as fingers or a retractor, just like in an actual surgery, as shown in FIG.

[0053] At this time, at the target site X, it can be seen that the muscle portion 12 has been reached by splitting the subcutaneous tissue portion 14, as the subcutaneous tissue portion 14 and the muscle portion 12 are the flesh color and red plastic (clay) colors, respectively.

[0054] Furthermore, by approaching the target area of ​​the femur while avoiding muscle areas 12, it is possible to know that the target area, fatty area 11, has been reached by the color of the yellow plastic body (clay) that makes up fatty area 11.

[0055] Furthermore, from this state, the surgeon can use surgical instruments such as his / her fingers or a retractor to approach the target area of ​​the femur, just like in an actual surgery, as shown in Figure 7, thereby removing fatty area 11 and exposing the surgical target area 1' of the simulated bone 1.

[0056] 8, the surgeon sets retractors Y and Z above and below the target site X where the surgical site 1' is exposed, just like in an actual surgery. At this time, the surgeon sets the upper retractor Y so that its blade at the tip is placed between the surgical site 1' and the muscle portion 12. In addition, while checking the blood vessel portion 13 with his finger, the surgeon sets the lower retractor Z so that the blade of the retractor Z is placed between the surgical site 1' and the blood vessel portion 13 (and the muscle portion 12).

[0057] In this manner, the surgical site 1' is exposed from the target site X, and then cut with a bone cutting tool or the like. This makes it possible to perform training that reproduces an actual surgery in which the field of view is limited by muscles, etc., unlike conventional training that uses an imitation bone in which the entire bone is exposed.

[0058] As explained in detail above, according to the bone surgery training device using the simulated bone 1 of this embodiment, by sequentially arranging plastic bodies having colors corresponding to the fat portion 11, the muscle portion 12, and the subcutaneous tissue portion 14 on the simulated bone 1, it is possible to easily and reliably form biological tissues, etc. that need to be handled during bone surgery in association with the simulated bone 1.

[0059] In addition, by providing a tubular blood vessel portion 13 that corresponds to a blood vessel, surgical training can be performed that takes into account blood vessels that require special attention during bone surgery.

[0060] In addition, by wrapping the fat portion 11, muscle portion 12, blood vessel portion 13, and subcutaneous tissue portion 14 on the simulated bone 1 with a film-like skin portion 15, these can be integrated together and the skin membrane on the skin surface can be reproduced, making it possible to perform cutting with a scalpel, etc.

[0061] Here, by partially forming the fat portion 11, the muscle portion 12, the blood vessel portion 13, the subcutaneous tissue portion 14, and the skin portion 15 only in the area (target T) of the simulated bone 1 that is the subject of training, a simple configuration primarily intended for bone surgery can be realized, unlike a large-scale human body model.

[0062] On the other hand, the area (target T) of the simulated bone 1 that is the subject of training includes skin section 15, subcutaneous tissue section 14, blood vessel section 13, muscle section 12, and fat section 11, which correspond to the skin membrane, skin, muscle, blood vessels, and fat that the surgeon must take into consideration before reaching the bone or joint during surgery. Therefore, after treating these in the same manner as in an actual surgery, training can be performed to expose the area of ​​the simulated bone that is the subject of training.

[0063] In addition, since the colors and arrangements of the parts 11 to 15 correspond to actual living tissues, the surgeon performing the treatment can train while being aware of which living tissue is being treated.

[0064] Furthermore, the surgical area 1' of the simulated bone 1, which is the subject of training and exposed by the procedure, can also have the surgical field reproduced by muscle parts 12, etc., just as the field of view is actually limited by muscles, making it possible to simulate surgery such as resection of the simulated bone 1 itself in a manner that is close to actual surgery.

[0065] In this way, according to the bone surgery training tool using the simulated bone 1 of this embodiment, an actual surgery can be reproduced simply and reliably.

[0066] In this embodiment, the fat portion 11, the muscle portion 12, and the subcutaneous tissue portion 14 are made of clay (wood powder clay), which is a plastic body having a corresponding color, but the present invention is not limited to this. For example, they may be made of a colored resin material having viscoelasticity.

[0067] In addition, in this embodiment, the femur has been described as the simulated bone 1, but the simulated bone is not limited to a single one, and the target may be joint tissue constituted by the simulated bone. Furthermore, in addition to or instead of the above-mentioned fat portion 11, muscle portion 12, blood vessel portion 13, subcutaneous tissue portion 14, and skin portion 15, the simulated bone may be provided with part or all of a thread-like nerve portion equivalent to a nerve, a ligament portion equivalent to a ligament, and a tendon tissue portion equivalent to tendon tissue.

[0068] For example, as shown in Fig. 9, a muscle portion 12C corresponding to the quadriceps may be arranged for a simulated joint of a knee joint, which is a joint tissue between a simulated bone 1 of a femur and a simulated bone 1' of a tibia, and the muscle portion 12C may be connected to a simulated bone 10 of a patella via a tendon tissue portion 16A corresponding to the quadriceps tendon. Similarly, a configuration may be adopted in which the simulated bone 10 of a patella and a simulated bone 1' of a tibia are connected via a tendon tissue portion 16B corresponding to the patellar tendon. The ligament portions 16A and 16B are made of fiber bundles such as fiber bands, and each connection point is appropriately connected and fixed by adhesive, screws, or the like.

[0069] The simulated bone 1, which is the femur, and the simulated bone 1', which is the tibia, may be connected via ligament parts 17A, 17B corresponding to the lateral collateral ligament and the medial collateral ligament on both sides. The ligament parts 17A, 17B are made of a resin material, and each connection point is appropriately connected and fixed by adhesive, screws, or the like.

[0070] Furthermore, the nerve portion 18 corresponding to the saphenous nerve may be formed from a thread-like member and placed adjacent to the adjacent simulated bones 1, 1', muscle portion 12, etc.

[0071] By forming a subcutaneous tissue portion 14 and a skin portion 15 on the joint tissue (fat portion 11 and blood vessel portion 13 are omitted) made of the simulated bone constructed as described above, a surgical training device for the knee joint can be constructed.

[0072] Although the knee joint has been described as the joint tissue, the present invention is not limited to this, and for example, the elbow joint may be configured as the target. [Explanation of symbols]
