Description

  The present invention relates to a magnetic body indwelling device detecting and gripping device for detecting and gripping a magnetic body indwelling device placed in a body cavity during a surgical operation or the like.

In the surgical operation by laparoscope or laparotomy, there is a scoring method as a treatment for grasping a lesion part generated inside a luminal organ such as the stomach or the large intestine. The inking method is a few days to a few weeks before the operation, from the inside of the luminal organ, the ink that serves as a mark is injected into the living tissue where the lesion has occurred, and the position of the lesion is determined from the outside of the luminal organ. It is a treatment that facilitates direct or indirect identification with the naked eye. Specifically, an endoscope is inserted from the mouth, and ink is injected by inserting a needle into the organ wall located near the lesion from the inside of the luminal organ. The injected ink spreads along the wall, and assists in visually confirming the lesioned part at the time of excision.
At this time, it is necessary to keep in mind that the needle tip does not penetrate through the wall portion and is injected at a depth that allows the position of the tattoo to be visually recognized when the luminal organ is viewed from the outside. If the needle penetrates the wall, not only the lesion site is unclear, but many other organs may be covered with ink so that the operation cannot continue. Also, if the ink can not be injected so that it can be seen outside the stomach or large intestine, the lesion site cannot be identified, which may cause the lesion to be left behind. In short, the problem with this inking method is that it requires a high technique for adjusting the depth of needle insertion so as to ensure the inking.

  In view of this, a method has been proposed that makes it possible to accurately grasp a desired location of a luminal organ without performing high-quality inking in laparoscopic or open surgery. The method is to place a magnetic body indwelling device in a predetermined position inside the lumen organ in advance, bring the magnetic forceps close to the outside of the lumen organ during the operation, and place the magnetic body inside the lumen organ. The indwelling device is pulled together with the biological tissue of the luminal organ to the magnetic forceps (see Non-Patent Document 1 below). According to this method, when the magnetic forceps are brought close to the outside of the lumen organ in which the magnetic body indwelling device is placed, the magnetic body indwelling device is attracted to the magnetic body forceps, and the wall of the lumen organ in which the magnetic body indwelling device is placed Deforms so that the part rises outward. Therefore, by visually recognizing the deformation from the outside of the luminal organ, the position where the magnetic body indwelling device is placed can be grasped easily and accurately in a short time.

In addition to attracting the magnetic body indwelling device placed inside the lumen organ to the magnetic forceps together with the biological tissue of the lumen organ, the magnetic body placement device can be adsorbed to the magnetic forceps together with the biological tissue of the lumen organ. Thus, it is possible to accurately grasp a desired portion of the luminal organ without damaging the living tissue.

By the way, in the method for exploring a luminal organ using a magnetic body as described above, a magnetic forceps from the outside of the luminal organ is located in the vicinity of the magnetic body indwelling device placed inside the luminal organ. It has been found that it may be difficult to bring
That is, in order to insert the magnetic forceps into the body, the probe is usually inserted using a probe insertion trocar inserted into the abdominal wall or the like. The indwelled position is not always outside the predetermined position inside the luminal organ. For this reason, when the position where the probe insertion trocar is inserted deviates greatly from the predetermined position inside the lumen organ where the magnetic body indwelling device is placed, or the extension direction of the magnetic forceps inserted from the probe insertion trocar is When the magnetic body indwelling device is placed in a position that does not face the outside of the predetermined position inside the lumen organ, it is difficult to bring the magnetic body forceps closer to the magnetic body indwelling device.

  The present invention has been made in view of the above circumstances, and even when the position where the probe insertion trocar is inserted is slightly deviated from the predetermined position inside the lumen organ where the magnetic body indwelling device is placed, It is an object of the present invention to provide a magnetic indwelling device detection and gripping device capable of easily approaching a magnetic indwelling device with a magnetic material for detection inserted through an insertion trocar.

As means for solving the above-described problems, a magnetic indwelling device detection and gripping device having the following configuration is employed.
That is, the magnetic body detainer detection and grasping apparatus according to the present invention has a magnetic body placed closer to the outside of the lumen organ and the magnetic body detainer placed at a predetermined position inside the lumen organ. The magnetic body indwelling device detecting and gripping device for detecting the magnetic body indwelling device by pulling the magnetic body together, the magnetic body, a probe main body for retracting and retracting the magnetic body, and the magnetic body And a connecting member made of a flexible material for connecting the body and the probe main body.

  In the device for detecting and grasping a magnetic body indwelling device of the present invention, for example, the probe body is inserted into the body using a probe insertion trocar inserted into the abdominal wall or the like, and the magnetic body protruded therefrom is inserted into the lumen. From the outside of the organ, the magnetic body indwelling device placed at a predetermined position inside the hollow organ is brought close to the organ. In this case, since the probe main body and the magnetic body are connected by a connecting material made of a flexible material, the magnetic body is freely moved in other directions without being limited to the extending direction of the probe main body. be able to. As a result, for example, even when the position where the probe insertion trocar is inserted is slightly deviated from the predetermined position inside the lumen organ where the magnetic body placement device is placed, the magnetic body projected from the probe body is magnetically It can be easily approached to a body detainer.

In the magnetic indwelling device detection and gripping device of the present invention, the connecting member is made of a wire, and the probe main body is attached to a wire take-up portion that winds the proximal end side of the wire and a tip of the wire. It is preferable that a release mechanism for releasing the magnetic substance is provided.
In this case, the release direction is determined in advance, and the magnetic body attached to the tip of the wire is released from the probe body by the release mechanism. The magnetic body is released into the body while being connected to the wire. If there is a magnetic indwelling device in the vicinity of the released part, the magnetic body indwelling device can be attracted to the magnetic material side together with the living tissue of the lumen organ by the attractive force between the magnetic indwelling device and the magnetic material. . On the other hand, if there is no magnetic indwelling device in the vicinity of the released portion, the magnetic indwelling device cannot be drawn by the released magnetic material. At this time, the magnetic body is pulled toward the probe main body by winding the wire with a wire winding device. Then, the attracted magnetic body is released again by the release mechanism while changing the release direction from the previous one. Such release of the magnetic body and winding of the wire are repeated until the magnetic body is brought close to the magnetic body indwelling device.

In the detection device and the gripping device for a magnetic indwelling device according to the present invention, the connecting member includes a flexible shaft, and the probe main body is provided with a bending adjustment mechanism that adjusts a bending direction and a bending angle of the flexible shaft. It is preferable.
In this case, the tip of the probe body is inserted into the body using a probe insertion trocar inserted into the abdominal wall or the like, and the magnetic body is protruded therefrom through a flexible shaft. At this time, since the bending direction and the bending angle of the flexible shaft can be adjusted by the bending adjusting mechanism, the magnetic body attached to the distal end of the flexible shaft can be adjusted over a wide range while being along the outer surface of the lumen organ. Can be moved across.

In the magnetic indwelling device detection and gripping apparatus of the present invention, it is preferable that the magnetic body is composed of a plurality of magnetic body pieces connected in series by wires.
In this case, magnetic pieces protruding from the probe body can be arranged in series along a predetermined position in the body, for example, along the outer surface of the luminal organ. That is, the magnetic substance piece can be arranged in the form of a line instead of a point with respect to the magnetic substance detainer, and the magnetic substance detainer can be efficiently detected by the magnetic piece arranged in the form of these lines.

In the magnetic indwelling device detection and gripping device of the present invention, the magnetic body is preferably formed in a spherical shape.
In this case, since the magnetic body protruding from the probe main body is formed in a spherical shape, there is little risk of damaging the body by the magnetic body, and the magnetic body can be moved quickly in the body.

  According to the present invention, even when the position where the probe insertion trocar is inserted is slightly deviated from the predetermined position inside the lumen organ where the magnetic body indwelling device is indwelled, the probe insertion trocar is inserted through the probe insertion trocar. The magnetic body can be easily brought close to the magnetic body indwelling device.

<First Embodiment>
A first embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the probe (magnetic body indwelling device detection and gripping device) 1 of this embodiment detects a probe body 10 and a magnetic body indwelling device placed at a predetermined position inside the lumen organ of the patient. The magnet 11 for a detection, and the wire 12 which connects the probe main body 10 and the magnet 11 are provided.

  The probe main body 10 includes an outer cylinder 14 having a flange portion 13 at a proximal end, and an inner cylinder 15 inserted into the outer cylinder 14 so as to be movable along the axial direction thereof. The inner cylinder 15 is closed at the base end by a lid 15a, and a cap 15b is screwed to the distal end (see FIG. 3). A bolt 17 is attached to the base end portion of the outer cylinder 14 so as to protrude from the inner peripheral surface, and the tip of the bolt 17 is inserted into a groove 18 provided in the inner cylinder 15. The outer cylinder 13 is movable in the axial direction relative to the inner cylinder 15 by a length that allows the tip of the bolt 17 to move in the groove 18.

The probe main body 10 is provided with a wire winding portion 19 that winds the proximal end side of the wire 12 and a discharge mechanism 20 that discharges the magnet 11 attached to the distal end of the wire 12.
The wire winding unit 19 includes a winding shaft 21 that is provided at the proximal end portion of the inner cylinder 15 and winds the proximal end side of the wire 12, and an operation handle 22 that rotates the winding shaft 21.

  As shown in FIG. 3, the discharge mechanism 20 is housed in the inner periphery of the tip of the cap 15 b and presses the rear end of the magnet 11 to release the magnet 11 at a substantially constant speed. A coil spring 24 that is disposed inside the member 23 and biases the pressing member 23 toward the distal end side of the probe body 10 and a distal end of the cap 15b of the inner cylinder, and locks the magnet 11 to the distal end of the probe body 10. It consists of a stopper 25.

  The pressing member 23 is formed with a flange portion 26 protruding outward at the proximal end, and the flange portion 26 is inserted into a gap 15d formed inside the proximal-side thin portion of the cap 15b. The pressing member 23 is movable in the axial direction with respect to the inner cylinder 15 by a length that allows the collar portion 26 to move within the gap 15d of the proximal-side thin portion of the cap 15b.

  The coil spring 24 is interposed between an inner collar portion 27 provided at the distal end of the pressing member 23 and the distal end of the inner cylinder main body 15c. A plurality of stoppers 25 are arranged at a predetermined angle in the circumferential direction at the tip of the inner cylinder cap 15b. Each stopper 25 is pin-coupled to be rotatable, and is urged so as to spread outward by a spring 28 fitted on the pin. In addition, an inclined portion 29 is formed inside the tip of the stopper 25 so that the detection magnet 11 can easily enter the inner cylinder 15.

As shown in FIG. 3, when the outer cylinder 14 is moved to the tip of the cap 15b, the stopper 25 is in a magnet-locked state in which rotation to the outside is restricted due to interference with the outer cylinder 14. Further, when the outer cylinder 14 is moved to the proximal end side as shown in FIG. 1, the stopper 25 is not interfered by the outer cylinder 14 and is rotated outward by the urging force of the spring 28 so that the magnet is not locked. It becomes a state.
The parts constituting the probe are coated with a material that is not harmful to the body, such as titanium or silicon, as necessary, as in the indwelling tool 30 described later.

Next, the operation of the probe 1 of the present embodiment having the above configuration will be described.
As shown in FIG. 4, an indwelling tool 30 is placed in advance, for example, inside the stomach of a patient. The indwelling device 30 includes a clip 31 that is locked to the inner surface of the stomach, and a magnet 33 that is a magnetic material indwelling device connected to the clip 31 via a wire 32. As a method for indwelling the indwelling device 30, for example, an endoscope is inserted from the mouth, the indwelling device 30 is inserted inside the stomach through the insertion portion of the endoscope, and the stomach wall near the lesioned part B is grasped by the clip 31. There is a way to fix it.

In order to detect the magnet 33 for the magnetic indwelling device of the indwelling device 30 with the probe 1, a laparoscopic trocar 35 is inserted into the abdominal wall of the patient in the supine position, and the intraperitoneal cavity is inserted through the laparoscopic trocar 35. Inject carbon dioxide into the abdomen to inflate the abdominal cavity to ensure a surgical space. In addition, a necessary number of prober trocars 36 and treatment instrument trocars are inserted into the abdominal wall. In FIG. 4, only one prober insertion trocar 36 is shown.
A laparoscope 37 is inserted into the abdominal cavity through a laparoscopic trocar 35. A television camera is connected to the laparoscope, and the surgeon observes the inside of the abdominal cavity while viewing the image projected on the television monitor connected to the television camera.

  First, the probe 1 is inserted through the probe insertion trocar 36. Subsequently, the outer cylinder 14 is pulled forward while the tip of the probe 1 is directed in a predetermined direction. Thereby, interference by the outer cylinder 14 is eliminated, and each stopper 25 is rotated so as to expand outward by the biasing force of the spring 28. That is, the stopper 25 is brought into the magnet non-locking state, and the locking of the magnet 11 by the stopper 25 is released. The magnet 11 is urged by the coil spring 24 so as to be released outward through the pressing member 23 in advance, and the magnet 11 is pressed by the pressing member 23 at the same time that the stopper 25 is released. Then, while being connected to the wire 12, it is discharged to the outside, that is, into the patient's body. If there is a magnet 33 for the magnetic substance indwelling device in the vicinity of the released part, the magnet 11 for detection is attracted to the magnet 33 for the magnetic substance indwelling device by the attraction force with the magnet 33. When the wire 12 is taken up by the wire take-up unit 19, the magnet 33 for the magnetic substance indwelling device is attracted to the probe body 10 side while being attracted to the moving magnet 11. As a result, the stomach wall having the lesioned part B together with the magnet 33 is brought closer to the probe main body 10, and as a result, the stomach wall in which the magnet 33 for the magnetic substance indwelling device is placed is deformed so as to rise outward. The surgeon can visually recognize the deformation of the stomach wall from the image displayed on the television monitor and can grasp the place where the magnet 33 is placed. Thereafter, the wire 12 is further wound by the wire winding portion 19, whereby the stomach wall where the lesioned portion B is located can be grasped by the magnet's adsorption force.

  On the other hand, if there is no magnet 33 for the magnetic substance indwelling device in the vicinity of the released portion, the detection magnet 11 is not attracted to the magnet 33 for the magnetic material indwelling device. At this time, the wire winding unit At 19, the wire 12 is wound up, and the detection magnet 11 is pulled toward the probe body 10 side. Then, the attracted magnet 11 is reset at the tip of the probe main body 10 by the stopper 25, the tip of the probe main body 10 is directed in a direction different from the previous direction, and then the magnet 11 is discharged again by the discharge mechanism 20. Such detection of the detection magnet 11 and winding of the wire 12 are repeated until the detection magnet 11 detects the magnet 33 for the magnetic material placement device.

  According to the embodiment, since the probe body 10 and the detection magnet 11 are connected by the wire 12, the detection magnet 11 is not limited to the extending direction of the probe body 10, and other As a result, for example, the position where the probe insertion trocar 36 is inserted slightly deviates from the predetermined position inside the luminal organ where the magnet 33 for indwelling the magnetic substance is placed. Even when the detection magnet 11 is present, the detection magnet 11 protruding from the probe body 10 can be easily brought close to the magnet 33.

  In the above embodiment, a simple solid magnet 33 is used as the magnet for the magnetic substance indwelling device. However, as shown in FIG. 5, for example, a light emitting LED is attached as the magnet 40 for the magnetic substance indwelling device. You may use the thing and the thing to which the light emission marker was painted. In this case, it can be expected that the task of detecting the magnet 40 for the magnetic substance indwelling device becomes extremely easy.

In addition, as shown in FIG. 6, the direction of the lesioned part B may be indicated by using the direction when the detection magnet 42 is attracted to the magnet 41 for magnetic substance placement.
That is, when the magnet 41 for a magnetic substance indwelling device is to be placed on the stomach wall, for example, the direction of the magnet with respect to the lesioned part B (direction of N pole and S pole) is determined in advance using a plurality of clips 31. To do. On the other hand, an index 43 such as an arrow determined by the magnetization direction is attached to the surface of the detection magnet 42. Thereby, when the detection magnet 42 is attracted to the magnet 41 for magnetic substance placement device, it is possible to know the direction in which the lesioned part B exists with respect to the detection magnet 50 based on the index 43.

As a modification of this embodiment, as shown in FIGS. 7 and 8, a magnetic body 60 for detection may be composed of a plurality of magnetic body pieces 62 connected in series by wires 61. good.
In this case, the magnetic piece 62 protruding from the probe main body 10 can be arranged in a line in series along a predetermined position in the body, for example, the outer surface of the stomach wall. At this time, the magnetic piece 62 can be arranged in the form of a line instead of a point with respect to the magnet 33 for the magnetic indwelling device. If there is a magnet 33 for body indwelling device, the magnetic piece 62 and the magnet 33 for magnetic body indwelling device are attracted. As a result, the magnet 33 for the magnetic substance indwelling device can be detected efficiently.
This modification can also be applied to a second embodiment described later.

<Second Embodiment>
A second embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 9, the probe (magnetic body indwelling device detection and gripping device) 2 of this embodiment includes a probe body 70 and a magnet for a magnetic body indwelling device that is placed at a predetermined position inside a patient's luminal organ. And a flexible shaft 72 for connecting the probe main body 70 and the magnet 71 to each other.

  The probe main body 70 includes an outer cylinder 74 having a flange portion 73 at the base end, and an inner cylinder 75 that is inserted into the outer cylinder 73 so as to be movable along the axial direction thereof. The base end of the inner cylinder 75 is closed with a lid 75a. A bolt 77 is attached to the base end portion of the outer cylinder 74 so as to protrude from the inner peripheral surface, and the tip of the bolt 77 is inserted into a groove 78 provided in the inner cylinder 75.

The flexible shaft 72 is connected to the tip of the inner cylinder 75. The flexible shaft 72 has a bellows shape made of a flexible material such as rubber, or a thin resin or metal, and the magnet 71 is attached to the tip thereof.
A bending adjustment mechanism 80 is attached to the flexible shaft 72, and the bending direction and the bending angle of the flexible shaft 72 are adjusted by the bending adjustment mechanism 80.

As shown in FIG. 9, the bending adjustment mechanism 80 includes a wire 81 inserted into the inner cylinder 75 and the flexible shaft 72, an operation shaft 82 that moves forward and backward in a curved portion in the middle of the wire 81, and an operation shaft. It consists of a handle 83 for rotating 82. A plurality of ends of the wire 81 are connected to a magnet connecting portion 84 attached to the tip of the flexible shaft 72 at a predetermined interval.
According to the bending adjustment mechanism 80, when the handle 83 is tilted to the proximal end side or the distal end side of the inner cylinder 75, the operation shaft 82 is rotated in a predetermined direction. Accordingly, one end side of the wire 81 is pulled into the proximal end side of the inner cylinder 74, and the other end side of the wire 81 is pushed into the distal end side of the inner cylinder 74. Thereby, the flexible shaft 72 is bent in the X direction or the Y direction in FIG. The bending angle is determined by the tilt angle of the handle 83.
When the inner cylinder 75 is advanced or retracted with respect to the outer cylinder 74, the detection magnet 71 is operated to protrude from the distal end of the outer cylinder 74, or conversely, to be stored.

Next, the operation of the probe 2 of the present embodiment having the above configuration will be described.
First, as shown in FIG. 11, the tip of the probe 2 is inserted into the patient's body through the probe insertion trocar 36. Subsequently, after the tip of the probe 2 is directed in a predetermined direction, the inner cylinder 75 is pushed forward with respect to the outer cylinder 74, and the magnet 71 for detection is projected from the outer cylinder 74 together with the flexible shaft 72. Then, the handle 83 is tilted, and the flexible shaft 72 is bent in a predetermined direction via the wire 81. In this state, the probe 2 can be moved back and forth or rotated with respect to the probe insertion trocar, and the detection magnet 71 can be moved over a wide range while being moved along, for example, the outer surface of the stomach wall in the patient's body. As a result, for example, even when the position where the probe insertion trocar 36 is inserted is slightly deviated from the predetermined position inside the lumen organ where the magnet 33 which is a magnetic body indwelling device is placed, it is projected from the probe body 10. The detection magnet 71 can be easily brought close to the magnet 33 for the magnetic substance indwelling device.

In the above-described embodiment, the bottomed cylindrical magnet 71 is used as the detection magnet. However, the present invention is not limited to this, and as shown in FIG. A magnet 90 may be used. In this case, if the magnet 91 for a magnetic substance indwelling device is made to have an arm shape corresponding to the spherical magnet 90, it is possible to obtain a high attraction force.
In this case, since the detection magnet 90 protruding from the probe body is formed in a spherical shape, there is little risk of damaging the body by the magnet 90, and the magnet 90 can be moved quickly in the body. .
This modification is also applicable to the first embodiment described above.
Also in the second embodiment, as the magnet 33 for the magnetic substance indwelling device, a light emitting LED attached or a light emitting marker coated magnet may be used.

In each of the above embodiments, the process of placing the indwelling device inside the stomach has been described. However, the place where the indwelling device can be placed includes any luminal organ other than the stomach. For example, an indwelling device can be placed inside the large intestine. In that case, the endoscope is inserted from the anus.
In each embodiment, a magnet having its own magnetic force is used as a magnetic substance to be retained in the body. However, if the detection magnet emits a strong magnetic force, the magnetic substance to be retained in the body is used. There is no need to use a magnet, and it is sufficient to use a metal material that is attracted to the magnet when a magnetic force acts.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to said embodiment. Additions, omissions, substitutions, and other modifications can be made without departing from the spirit of the present invention. The present invention is not limited by the above description, but only by the scope of the appended claims.
