[0030] The utility model tissue and organ intervention device is applied in children's ultrasonic intervention surgery, and is used as a component inserted into tissues and organs in children's ultrasonic intervention surgery to introduce therapeutic agents into target tissues and organs.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, a tissue and organ intervention device 1 used in ultrasonic treatment surgery is provided, which includes a trunk unit configured with an insertion portion 40, and the trunk unit has a through hole extending along the rod length. The tissue and organ intervention device 1 can be inserted into multiple different positions of the tissue and organ and introduce a therapeutic agent. The tissue and organ intervention device 1 includes a center line O (dashed line), which is aligned with the center line of the trunk unit, the insertion portion 40 and the middle joint 90 along the center of the tissue and organ intervention device 1, wherein the trunk unit has a through hole extending along the rod length, and the trunk unit includes a trunk rod section 10 and an operation end 20. The figure also shows mutually perpendicular X-axis, Y-axis and Z-axis, wherein the X-axis corresponds to the length direction of the tissue and organ intervention device 1, the Y-axis corresponds to the height direction of the tissue and organ intervention device 1, and the Z-axis corresponds to the width direction of the tissue and organ intervention device 1. The negative X-axis direction side of the tissue and organ intervention device 1 is called the "operating end side" of the tissue and organ intervention device 1 and each component, and the positive X-axis direction side is called the "operating end side" of the tissue and organ intervention device 1 and each component. The surgical end of the tissue and organ intervention device 1 and its components is called the "surgical end", and the vicinity thereof is called the "surgical end". The operating end is operated by the operator and inserted into the target body. Figure 1 The following description is also common. Figure 1 for Figure 3 Cross-section along line AA.

[0032] like Figure 1As shown, the tissue and organ intervention device 1 is also equipped with surgical wires, for example, a first surgical wire 31 , a second surgical wire 33 , a third surgical wire 32 and a fourth surgical wire 34 .

[0033] The main rod segment 10 is a long rod component extending along the length direction (center line O) of the tissue and organ intervention device 1. The main rod segment 10 is a hollow rod component having a first solid portion 111 inside. Specifically, the main rod segment 10 forms a surgical wire hole for the surgical wire on its inner side (i.e., the first solid portion 111), and the main rod segment 10 is matched with the opening 19L and is in the shape of a hollow rod. In one embodiment, the surgical wire holes include a first surgical wire hole 11L, a second surgical wire hole 13L, a third surgical wire hole 12L, and a fourth surgical wire hole 14L.

[0034] The opening 19L is an opening for accommodating the insertion portion 40. Figure 1 As shown, the opening 19L is a hole extending in the first solid portion 111 of the trunk rod segment 10, communicating with the operating end to the surgical end of the trunk rod segment 10, and the surgical end of the opening 19L is connected to the entry hole formed in the surgical end 20. The operating end of the opening 19L is connected to the outside. The opening 19L includes a portion of the insertion portion 40 (such as the pressing portion 48 and the joint portion 49) (details are described later). Figure 3 As shown, the opening 19L and the surgical wire hole in the main rod section 10 Arranged in parallel. Opening 19L is located Figure 3 The inner diameter Φ9 of the opening 19L is larger than the surgical wire hole. The inner diameter is Φ1.

[0035] The surgical wire holes 11L to 14L for surgical wires are inner cavities for accommodating surgical wires 31 to 34. Figure 2 In the embodiment, the surgical wire holes 11L to 14L surround the opening 19L and are arranged in parallel. Figure 1 As shown, the first surgical wire hole 11L is an inner cavity formed in the first solid part 111 of the main rod section 10 and extending along the length direction (center line O). The surgical end of the first surgical wire hole 11L is closed, and the operating end is connected to the outside. The first surgical wire hole 11L accommodates the first surgical wire 31. The surgical end of the first surgical wire hole 11L has a stabilizing portion 51 for fixing the surgical end of the first surgical wire 31 to the surgical end of the first surgical wire hole 11L. Figure 3 As shown, the inner diameter Φ1 of the first surgical wire hole 11L is almost the same as the inner diameter Φ1 of the surgical wire holes 12L to 14L. The inner diameter Φ1 of the first surgical wire hole 11L is smaller than the inner diameter Φ9 of the opening 19L, but larger than the outer diameter Φ2 of the first surgical wire 31.

[0036] The second surgical wire hole 13L has the same structure as the first surgical wire hole 11L except that the second surgical wire 33 is accommodated. The third surgical wire hole 12L has the same structure as the first surgical wire hole 11L except that the third surgical wire 32 is accommodated. The fourth surgical wire hole 14L has the same structure as the first surgical wire hole 11L except that the fourth surgical wire 34 is accommodated. Figure 2 As shown, the inner diameters Φ1 of the surgical wire holes 11L to 14L are substantially the same, but they may also be different. Figure 2 As shown, the surgical wire holes 11L-14L are arranged at equal intervals around the tissue and organ intervention device 11, but they can also be arranged at uneven intervals.

[0037] The surgical end 20 is a component located at the surgical end of the tissue and organ intervention device 11, and enters the target body earlier than other components. The surgical end 20 is a hollow, approximately round rod-shaped component, which has a second solid portion 222 inside. Specifically, the surgical end 20 forms an entry hole 20h inside (i.e., the second solid portion 222), and this entry hole 20h is a through hole leading from the operating end of the surgical end 20 to the surgical end. The surgical end of the entry hole 20h (i.e., the opening 20o) is connected to the outside. The operating end of the opening 20h is connected to the opening 19L formed in the main rod section 10. The opening 20h includes insertion portions 41 to 44 and a joint 49 (see below for details). The outer diameter of the surgical end 20 is almost the same as the outer diameter of the main rod section 10. The length of the surgical end 20 can be determined arbitrarily.

[0038] The surgical wires 31 to 34 are used to bend the surgical end of the tissue and organ intervention device 1. The first surgical wire 31 is a hollow and filamentous component extending along the length direction of the tissue and organ intervention device 1. The first surgical wire 31 is approximately cylindrical and has an almost constant outer diameter Φ2. Figure 3 As shown, the outer diameter Φ2 of the first surgical wire 31 can be determined arbitrarily, as long as it is smaller than the inner diameter Φ1 of the first surgical wire hole 11L. Figure 2 As shown, the first surgical wire 31 is accommodated in the first surgical wire hole 11L. The surgical end of the first surgical wire 31 is fixed to the surgical end of the main rod section 10 by a stabilizing portion 51 and is held there. The operating end of the first surgical wire 31 is wrapped and fixed on the wire wrapping portion 92 (for example, the first wire wrapping portion 921, see below for details).

[0039] The second surgical wire 33 is different from the first surgical wire hole 11L. It is accommodated in the first surgical wire hole 13L, and the operating end is wrapped in the wire wrapping portion 92 (for example, the second wire wrapping portion 923). Apart from this, it has the same structure as the first surgical wire 31. The third surgical wire 32 is different from the first surgical wire hole 11L. It is accommodated in the third surgical wire hole 12L, and the operating end is wrapped in the wire wrapping portion 92 (for example, the third wire wrapping portion 922). Apart from this, it has the same structure as the first surgical wire 31. The fourth surgical wire 34 is different from the first surgical wire hole 11L. It is accommodated in the fourth surgical wire hole 14L, and the operating end is wrapped in the wire wrapping portion 92 (for example, the fourth wire wrapping portion 924). Apart from this, it has the same structure as the first surgical wire 31. Figure 3 In the example shown in FIG. 1 , the outer diameters Φ2 of the surgical wires 31 to 34 are substantially the same, but they may be different.

[0040] At least a portion of the surgical wires 31 to 34 may be composed of a plurality of portions having different shapes, outer diameters, and materials.

[0041] The insertion part 40 is used to insert tissues and organs and inject therapeutic agents into the tissues and organs. The insertion part 40 includes insertion parts 41-44, a joint 49 and a pressing part 48. In one embodiment, the insertion parts 41-44 include four insertion parts, namely the first insertion part 41, the second insertion part 43, the third insertion part (omitted) and the fourth insertion part 44. The first insertion part 41 is a hollow cylindrical shape, and its surgical end has an opening 41o. The surgical end of the first insertion part 41 is designed to gradually become sharper from the operating end to the surgical end to reduce the resistance when inserting the tissue organ. There is an opening on the side of the operating end of the first insertion part 41, through which the inner cavity of the first insertion part 41 is connected to the inner cavity of the joint 49. The outer diameter and inner diameter of the first insertion part 41 can be determined arbitrarily.

[0042] The second insertion portion 43 has the same structure as the first insertion portion 41 except that it has a surgical end opening 43o. The third insertion portion (omitted) has the same structure as the first insertion portion 41 except that it has a surgical end opening. The fourth insertion portion 44 has the same structure as the first insertion portion 41 except that it has a surgical end opening 44o. The insertion portions 41 to 44 are arranged in parallel along the length direction (center line O) of the tissue and organ intervention device 1. In addition, the insertion portions 41 to 44 are arranged at equal intervals around the tissue and organ intervention device 1. In one embodiment, the length from each surgical end of the insertion portions 41 to 44 to the joint 49 is approximately the same length L1. In this embodiment, the insertion portions 41 to 44 have approximately the same outer diameter and inner diameter, but they may also be different.

[0043] The joint 49 is a hollow component that joins the insertion parts 41 to 44. The joint 49 includes a bending part 491 and a hollow column 492. Each surgical end of the bending part 491 is connected to the side of each insertion part 41 to 44, covers the opening, and is connected to the operating end of the insertion part 41 to 44. The hollow column 492 protrudes from the approximate central part of the bending part 491 in the direction of the center line O. The surgical end of the hollow column 492 is connected to the bending part 491, and the operating end of the hollow column 492 is connected to the clamping part 48. The clamping part 48 is a long component extending along the length direction (center line O) of the tissue and organ intervention device 1. The clamping part 48 is a hollow cylindrical component. The clamping part 48 is located at the operating end of the joint 49. The surgical end of the clamping part 48 is connected to the hollow column 492 of the joint 49, and the operating end of the clamping part 48 is exposed to the outside. The operating end portion of the pressing portion 48 may be provided with a syringe for introducing the therapeutic agent into the therapeutic agent channel 40L or an operating member for operation.

[0044] Such a structure forms a therapeutic agent channel 40L inside the insertion part 40, and the channel is connected from the operating end of the clamping part 48 to the surgical end (openings 41o to 44o) of the insertion parts 41 to 44. In other words, the therapeutic agent provided by a device such as a syringe connected to the operating end of the clamping part 48 passes through the inside of the clamping part 48, through the inside of the joint part 49, and is ejected from the surgical ends of the insertion parts 41 to 44 respectively. In addition to being inserted by the insertion parts 41 to 44, the entirety of the insertion part 40 is located inside the trunk unit (trunk rod section 10, surgical end 20), as shown in FIG. Figure 2 shown.

[0045] like Figure 2 As shown, the intermediate joint 90 is sleeved on the operating end of the trunk rod section 10 for the operator to grasp. The intermediate joint 90 includes a trunk section 91, a wire wrapping section 92 and a radially extending wing section 93. The trunk section 91 is a component that forms a channel of the insertion portion 40. The trunk section 91 has an opening at the surgical end and the operating end, and forms an inner cavity, which connects the two openings and is hollow inside.

[0046] The wire wrapping portion 92 is used to wrap or lower the surgical wires 31 to 34. The wire wrapping portion 92 has four wire wrapping portions (a first wire wrapping portion 921, a second wire wrapping portion 923, a third wire wrapping portion 922, and a fourth wire wrapping portion 924). The first wire wrapping portion 921 has an annular portion and a toggle portion disposed outside the annular portion. The annular portion of the first wire wrapping portion 921 is disposed at the operating end of the first surgical wire 31 and is fixed. By rotating the toggle portion of the first wire wrapping portion 921 clockwise, the operating end of the first surgical wire 31 can be wound around the annular portion, thereby pulling the operating end of the first surgical wire 31. By rotating the toggle portion of the first wire wrapping portion 921 counterclockwise, the operating end of the first surgical wire 31 can be lowered from the annular portion, thereby loosening the first surgical wire 31.

[0047] The second wire wrapping portion 923 has a structure similar to the first wire wrapping portion 921, except that the operating end of the second surgical wire 33 is fixed to the ring portion. The third wire wrapping portion 922 has a structure similar to the first wire wrapping portion 921, except that the operating end of the third surgical wire 32 is fixed to the ring portion. The fourth wire wrapping portion 924 has a structure similar to the first wire wrapping portion 921, except that the operating end of the fourth surgical wire 34 is fixed to the ring portion.

[0048] The radially extending wings 93 are two wing-shaped parts located at the operating end of the wire wrapping portion 92. The radially extending wings 93 are used by the operator to grasp the tissue and organ intervention device 11. The radially extending wings 93 can have any shape and can also be omitted. The radially extending wings 93 can be formed integrally with the trunk section 91 and the wire wrapping portion 92.

[0049] The main rod section 10, the insertion parts 41-44, the pressing part 48 and the joint part 49 should be flexible and biocompatible, and can be made of resin material or metal material. For example, the resin material can be polyamide resin, polyurethane resin, etc. The metal material can be stainless steel such as nickel-titanium alloy, cobalt-chromium alloy, etc.

[0050] The insertion parts 41-44 and the joint part 49 (bend part 491, hollow column part 492) are preferably made of a material with higher rigidity than the pressing part 48. In this way, the insertion rigidity of the insertion parts 41-44 and the rigidity of the joint part 49 supporting the insertion parts 41-44 are higher than the rigidity of the pressing part 48, so that the insertion of tissues and organs can be smoothly performed.

[0051] The surgical end 20 is preferably flexible, and can be made of, for example, a resin material such as polyurethane, polyurethane elastomer, etc. The surgical wires 31-34 can be made of a metal material, such as tungsten alloy, etc. The stabilizing parts 51-53 can be made of any adhesive. The intermediate joint 90 can be made of a resin material, such as polyamide, etc. It should be noted that the above-mentioned various materials are only examples, and other known materials can also be used to manufacture various components.

[0052] like Figure 4 As shown, the transmission and bending of the tissue and organ intervention device 1 are embodied. Figure 4 The upper part shows the whole of the tissue and organ intervention device 1, and the lower part shows an enlarged view of the surgical end of the tissue and organ intervention device 1. First, the operator inserts the tissue and organ intervention device 1 into the target body, and transfers the surgical end 1d of the tissue and organ intervention device 1 to the desired position, that is, the target position for injecting the therapeutic agent.

[0053] Then, the operator bends the surgical end 1d of the tissue and organ intervention device 1 to the desired direction. In the tissue and organ intervention device 1, by rotating the toggle portion with the first wire wrapping portion 921 clockwise, the surgical end of the tissue and organ intervention device 1 can be bent outward (i.e., in a direction intersecting the long axis of the tissue and organ intervention device 1) by pulling the operating end of the first surgical wire 31. At this time, the tissue and organ intervention device 1 will bend in the first direction W1 (see FIG. 1 ) in which the first surgical wire 31 is set. Figure 3 , Figure 4 Similarly, by rotating the handle of the second wire wrapping portion 923 clockwise, the operating end of the second surgical wire 33 can be pulled to bend the surgical end of the tissue and organ intervention device 1 outward. At this time, the tissue and organ intervention device 1 will move in the second direction W3 (see FIG. Figure 2 , Figure 4 Similarly, by rotating the toggle portion with the third wire wrapping portion 922 clockwise, the surgical end of the tissue and organ intervention device 1 can be moved toward the third direction W2 (see Figure 2 By rotating the toggle portion of the fourth wire wrapping portion 924 clockwise, the surgical end of the tissue and organ intervention device 1 can be moved in the fourth direction W4 (see Figure 2 )bending.

[0054] In this process, if the outer diameter of the first surgical thread 31 is different from the outer diameter of the second surgical thread 33, Figure 4 As shown, when the tissue and organ intervention device 1 is bent in the first direction W1, the curvature radius r1 is different from the curvature radius r3 when it is bent in the second direction W3. It should be noted that by making a difference in the shape, outer diameter or material of one or more parts of the first to fourth surgical wires 31 to 34, the curvature radii r1 and r3 when bent and the length of the bendable part can also be adjusted.

[0055] like Figure 5 As shown, the insertion is performed using the tissue and organ intervention device 1. After the surgical end 1d of the tissue and organ intervention device 1 is transferred to the target position for injection of the therapeutic agent, the surgical end of the tissue and organ intervention device 1 is bent to the desired direction, and the operator pushes the operating end of the insertion portion 40 (i.e., the operating end of the pressing portion 48) toward the surgical end (see FIG. Figure 4 In this way, Figure 5As shown, the insertion parts 41-44 extend from the access hole 20h of the surgical end 20 and can be inserted into tissues and organs (e.g., brachial blood vessels). After the tissues and organs are inserted, the operator pulls the operating end of the insertion part 40 (i.e., the operating end of the pressing part 48) backward to accommodate the insertion parts 41-44 in the access hole 20h. In this way, the safety of the tissue and organ intervention device 1 can be improved by accommodating the insertion parts 41-44 in the access hole 20h at times other than insertion.

[0056] In summary, in the tissue and organ intervention device 1, the first insertion part 41 and the second insertion part 43 are arranged side by side and connected by the joint part 49, and the pressing part 48 is provided at the operating end of the joint part 49. Therefore, after one positioning, by pushing the pressing part 48 inward, the first insertion part 41 and the second insertion part 43 are pushed out from the surgical end 20 (i.e., the entry hole 20h), multiple tissues and organs at different positions can be inserted at the same time (see Figure 5 ). That is, compared with using independent (unconnected) first insertion part 41 and second insertion part 43 to insert separately, this operation is easier and the time required for treatment can be shortened. In addition, the first insertion part 41, the second insertion part 43, the joint part 49 and the pressing part 48 are each hollow, and the therapeutic agent can be ejected from the surgical ends of the first insertion part 41 and the second insertion part 43 through the inside of the pressing part 48 and the inside of the joint part 49. Therefore, after one positioning and insertion, by injecting the therapeutic agent from the operating end of the pressing part 48, the therapeutic agent can be injected into multiple different positions of the tissue organ from the first insertion part 41 and the second insertion part 43 at the same time. Compared with two separate material supply sources that provide the therapeutic agent to the first insertion part and the second insertion part respectively, the therapeutic agent can be supplied at the same time, so the management of the therapeutic agent is easier. Therefore, according to the tissue organ intervention device 11 of the first embodiment, the management of the therapeutic agent of the tissue organ intervention device 1 for therapeutic agent injection can be simplified and the time required for treatment can be shortened.

[0057] In addition, according to the tissue and organ intervention device 1, since the length from the surgical end of the first insertion part 41 to the joint part 49 (bending part 491) is equal to the length from the surgical end of the second insertion part 43 to the joint part 49 (bending part 491), it can be evenly inserted into the tissue and organ to a certain depth.

[0058] The tissue and organ intervention device 1 of the first embodiment has first surgical thread holes 11L to fourth surgical thread holes 14L for accommodating the first surgical thread holes 31 to fourth surgical thread holes 34. By pulling the operating end for operating the first surgical thread holes 31 to fourth surgical thread holes 34, the front end of the tissue and organ intervention device 1 can be bent, and the front end portion 1d of the tissue and organ intervention device 1 can be pushed to the target position of the tissue and organ ( Figure 4). Therefore, according to the tissue and organ intervention device 1 of the first embodiment, in the tissue and organ intervention device 1 for drug injection, the insertion position can be easily controlled.

[0059] The tissue and organ intervention device 1 of the first embodiment further comprises a first surgical thread 31 and a second surgical thread 33, which are respectively accommodated in the first surgical thread hole 11L and the second surgical thread 13L. Therefore, by operating the first surgical thread 31 and the second surgical thread 33, the bending directions W1 and W3 ( Figure 4 ). This enables more precise control of the insertion position in the tissue and organ intervention device 1.

[0060] The second embodiment of the tissue and organ intervention device 1 adopts an insertion part 40A to replace the insertion part 40. The insertion part 40A includes a component called a hollow inner column portion 60, which extends along the length direction (center line O) of the tissue and organ intervention device 11A. The hollow inner column portion 60 is a hollow approximately cylindrical shape with openings at the surgical end and the operating end. The outer diameter of the hollow inner column portion 60 is smaller than the inner diameters of the clamping portion 48 and the hollow column portion 492. The length of the hollow inner column portion 60 is greater than the sum of the length of the clamping portion 48 and the length of the hollow column portion 492. As Figure 6 As shown, the hollow inner column portion 60 is inserted into the interior of the clamping portion 48 and the hollow column portion 492. The surgical end of the hollow inner column portion 60 is connected to the outside through the opening 60o on the bending portion 491A. The operating end of the hollow inner column portion 60 protrudes from the operating end of the clamping portion 48 and is connected to the outside through the opening of the operating end. The interior of the hollow inner column portion 60 is used as a suction channel (suction cavity 60L) of the suction device connected to the operating end side of the hollow inner column portion 60. In addition, the interior of the hollow inner column portion 60 can also be used as an equipment cavity of the tissue and organ intervention device 11A, which is used to guide medical equipment such as guide wires.

[0061] The doctor can provide the front end portion of the tissue and organ intervention device 11A and bend it to a desired direction, and then insert it using the first insertion part 41 to the fourth insertion part 44. Subsequently, the doctor can fix the front end portion of the tissue and organ intervention device 11A to the target position of the tissue and organ by applying negative pressure to the suction device connected to the operating end of the hollow inner column part 60.

[0062] The structure of the insertion portion 40A can be modified in various ways, and can include a hollow inner column portion 60 that forms the suction lumen 60L and the device lumen. The structure of the hollow inner column portion 60 can also be modified in various ways.
