In addition, a flexible synthetic resin tube 3 having a diameter slightly smaller than this is maintained.

The connector portion 2 is made of metal or hard composite on the tip portion (left end portion in FIG. 3) of a straight tube-shaped connector main body portion 2b which extends substantially straightly on the opposite side of the tip shaft 2a. A straight tubular branch end 2c made of resin is integrally connected at a predetermined acute angle (for example, 45 degrees) to form a substantially Y-shaped tubular shape.

The connector portion 2 appropriately supplies a fluid such as water or compressed air having a predetermined pressure to the open end portion 2b1 at the right end portion in FIG. 1 of the main body portion 2b, and supplies the supplied fluid to the outside. A fluid connector for detachably connecting a fluid supply / discharge device (not shown) for discharging is configured.

Further, the connector portion 2 has its branched end portion 2c.
The open end portion 2c1 is formed at the wire insertion port through which the guide wire 4 is inserted. The guide wire 4 is made of a flexible metal wire having a smaller diameter than the inner diameter of the tube 3 and long.

Further, the connector portion 2 can be adjusted in the insertion direction and the length of the guide wire 4 as appropriate by manually orienting the distal end shaft 2a in the appropriate direction or by rotating or moving the distal end shaft 2a. That is, the connector portion 2 can adjust the insertion length for inserting the guide wire 4 into the wire insertion opening 2c1 to appropriately adjust the depth at which the guide wire 4 is inserted into the subject. Is configured.

The tube 3 is made of, for example, a soft vinyl chloride resin or a polyurethane resin in order to obtain a waist (rigidity) required to have appropriate so-called pushability (pushability), torque transmission and followability. For example, the small diameter may be formed to 3 mm to 20 mm, and a lubricant such as silicone oil may be contained in order to make the sliding of the guide wire 4 and the movable magnet 9 described later favorable.

The pushability means the force of pushing the tube 3 from the base end side (for example, the connector portion 2) to the tip end side by the operator in order to advance the tube 3 in the organ such as the intestinal tract or the blood vessel. 3 is a characteristic that can be reliably transmitted from the base end side to the tip end side.

The torque transmissibility is a characteristic that the rotational force about the axis applied on the proximal end side of the tube 3 (for example, the connector portion 2) can be reliably transmitted to the distal end side of the tube 3. Further, the followability means the followability that allows the tube 3 to smoothly and surely advance along the preceding guide wire 4 in an organ such as a bent intestine or blood vessel.

Then, as shown in FIG. 3, a tip guide portion 5 is formed at the tip portion (left end portion in FIG. 3) of the tube 3.

As shown in FIGS. 1 and 2, the tip guide portion 5 is provided at the opening tip of the tube 3, for example, on the back surface of the required fixed disk-shaped fixed magnet 6 (right end surface in FIGS. 1 and 2). Are fixed concentrically with an adhesive or the like, and the fixed magnet 6 is formed to have a larger diameter than the tube 3 by, for example, a rare earth element magnet. The fixed magnet 6 has an outer surface coated with an acid resistant film and an antithrombotic film.

Further, a tip guide 7 having a bottom surface having substantially the same diameter and the same diameter as the tip surface of the fixed magnet 6 is adhered to the tip surface of the fixed magnet 6 (the left end surface in FIGS. 1 and 2). It is fixed concentrically with the agent.

The tip guide 7 is made of a dissolving material which dissolves in the body fluid in the subject, and has a pair of left and right insertion holes 7a, 7a penetrating in the direction of its central axis in FIG. The guide wire 4 is inserted into the insertion hole 7a and is extended to the far side (left side in FIGS. 1 and 2), and the guide wire 4 is fixed to the tip guide 7 with an adhesive in the insertion hole 7a. There is.

Then, the tip guide portion 5 fixes the flexible balloon 8 which is inflatable and defensible at a portion retracted by a predetermined length from the tip of the tube 3 toward the connector portion 2 side, and the inner cavity of the balloon 8 is fixed. The tube 3 is provided with a plurality of communication holes 8a, 8a which communicate with each other. The tube 3 has a flow path through which a fluid such as water or air flows, and the guide wire 4 is axially inserted through the passage. However, the fluid passage and the insertion passage of the guide wire 4 may be formed separately.

The balloon 8 is formed into a spherical shape from, for example, silicone rubber, natural rubber, or soft vinyl chloride resin, and when contracted, the balloon 8 contracts to a diameter substantially the same as the outer diameter of the tube 3.
At the time of expansion, the fixed magnet 6 and a disk-shaped movable magnet 9 described later are formed so as to expand to a diameter of about the same or more.

That is, the balloon 8 has a force and a size that can sufficiently prevent the movable magnet 9 from moving to the fixed magnet 6 side by the mutual magnetic attraction force with the fixed magnet 6 as a stopper. It is configured. The thickness of the balloon 8 is preferably thin considering that the movable magnet 9 passes over the outer surface of the balloon 8 when it is deflated, but a certain thickness is taken into consideration when considering the blocking force that blocks the movement of the movable magnet 9 when it is expanded. Is required. Specifically, for example, 0.1 mm to 1
A thickness of mm is desirable. Further, in order to confirm the position of the balloon 8, a radiopaque marker or a paint such as an adhesive may be applied.

The movable magnet 9 is elastically abutted on the side surface (the right side surface in FIG. 1) of the balloon 8 at the time of inflation and is fitted on the outer peripheral surface of the tube 3 with play. Different magnetic poles are arranged facing each other with a predetermined distance so that they can always be attracted to the fixed magnet 6 side by the mutual magnetic attraction force with the fixed magnet 6. The outer surface of the movable magnet 9 is coated with an acid resistant film and an antithrombotic film.

The movable magnet 9 is made of, for example, a rare earth element magnet, and is formed to have substantially the same shape and size as the fixed magnet 6, for example, and has a sliding hole 9a penetrating in the plate thickness direction at its axial center portion.
The sliding hole 9a is formed in such a size that it can slide over the outer peripheral surface of the balloon 8 and move toward the fixed magnet 6 side when the balloon 8 is deflated.

The distance l between the movable magnet 9 and the fixed magnet 6 can be adjusted appropriately by cutting the tip of the tube 3 as appropriate, and the distance l is shown in FIGS. 4, 5 and 6. Necessary anastomosis (or stenosis) such as jejunostomy 10
It is adjusted in advance according to the length of the communication hole 10a.

Next, an example of a method of using the organ anastomosis apparatus 1 thus configured will be described.

First, the supply valve of a fluid supply / discharge device (not shown) connected to the fluid connector 2b1 of the connector section 2 shown in FIG. 3 is opened to supply water or air having a predetermined pressure to the predetermined flow rate connector section 2. Then, this connector part 2
And the distal end shaft 2a through the inner cavities of the tube 3 and the balloon 8 through the plurality of communication holes 8a and 8b.
It is supplied inside and the balloon 8 is inflated.

As a result, the inflated balloon 8 prevents the movable magnet 8 from moving to the fixed magnet 6 side by mutual magnetic attraction, as shown in FIGS.

Next, in this state, the organ anastomosis device 1 is gradually inserted into the subject such as the human body, with the tip guide portion 5 of the organ anastomosis device 1 preceded by the guide wire 4. Then, the insertion of the guide wire 4 and the tip guide portion 5 into the subject is confirmed while looking at the X-ray fluoroscopic screen of an X-ray fluoroscopic monitor (not shown). For example, a required anastomosis portion 10 (or a gastrojejunostomy portion) (or The tip guiding portion 5 is guided to the narrowed portion).

After this, as shown in FIG.
By pushing the tip guide 7 further into the anastomosis portion 10a against the elastic force of the anastomosis portion 10 to push the tip guide 7 and the fixed magnet 6 forward of the anastomosis portion 10 (left side in FIG. 5). ) To.

As a result, as shown in FIG.
A fixed magnet 6 and a movable magnet 9 are arranged on both left and right sides of 0, respectively.

Therefore, the discharge valve of the fluid supply / discharge device connected to the connector portion 2 on the near side is opened to open the balloon 8
The water or air filled inside is discharged to the outside through the communication hole 8a of the tube 3 and the inner cavity of the tube 3. For this reason, the balloon 8 is rapidly deflated.

By the way, the movable magnet 9 is constantly urged by the mutual magnetic attraction between the movable magnet 9 and the fixed magnet 6 so as to be always attracted to the fixed magnet 6 side. Since the balloon 8 is deflated, the movable magnet 9 slides on the deflated balloon 8 and moves to the fixed magnet 6 side, and the fixed magnet 6 and the movable magnet 9 strengthen the anastomosis portion 10. Clamp it.

FIG. 6 shows the fixed magnet 6 and the movable magnet 9 as described above.
The state in which the anastomosis portion 10 is clamped is shown by. As described above, when the anastomotic portion 10 is fixed and strongly pressed by the movable magnets 6 and 9 for a required time, the cellular tissue of the pressed portion of the anastomotic portion 10 is apoptotic, and fixed.
A second communication hole 11 having a diameter substantially the same as the inner diameters of the movable magnets 6 and 9.
Are formed concentrically or eccentrically on the outer peripheral side of the communication hole 10a of the anastomotic portion 10.

Therefore, the narrow communication hole 1 of the anastomosis portion 10
0a expands to the second communication hole 11 having a larger diameter than this, and the stenosis of the anastomosis part 10 is reduced or eliminated. Also, the second
When the communication hole 11 is formed, the outer peripheral edge of the second communication hole 11 is fused and a new anastomosis is formed. in this way,
Tissues that are pinched by the fixed and movable magnets 6 and 9 to cause apoptosis are pulled out of the subject through the tip guide portion 5 in the pinched state and collected.

Further, by the connector portion 2 arranged outside the subject, the guide of the tip guide portion 5 inserted into the subject can be remotely controlled from the outside of the subject, and
Since the remote operation is performed while viewing the tip guide part 5 in the subject on the X-ray fluoroscopic screen, the guide accuracy of the tip guide part 5 can be improved, and the tip guide part 5 can be moved to a desired anastomosis part (or stenosis). Part) can be inserted or guided with high precision, easily and quickly. This can reduce the pain of the patient who is the subject.

Furthermore, since the acid resistant film and the antithrombogenic film are coated on both outer surfaces of the fixed and movable magnets 6 and 9, the fixed and movable magnets 6 and 9 are oxidized by body fluid in the subject. While it is possible to prevent or reduce the change and deterioration of the blood flow, it is possible to prevent blood clots from being generated by the fixed and movable magnets 6 and 9 in blood.

Furthermore, since the tip guide 7 is dissolved by the body fluid in the subject, it is not necessary to collect the tapered guide after use in the subject. For this purpose, the tip guide 7
The recovery processing work can be omitted.

Since the fixed and movable magnets 6 and 9 are magnets of rare earth elements, the magnetic force of these fixed and movable magnets 6 and 9 can be strengthened. Therefore, even when the anastomosis portion 10 and the communication hole 10a of the narrowed portion have a long length, it is possible to easily and surely attract the two magnets 6 and 9 and to reduce the size and weight of the magnets 6 and 9. Can be achieved.

Further, the length 1 from the tip of the movable magnet 9 (the left end in FIG. 1) to the tip of the tube 3 is calculated as follows:
The anastomosis portion 10 can be adjusted by simply cutting the tip of the anastomosis portion 10.
The length of the communication hole (or the narrowed portion) 10a can be easily and quickly adjusted.

In the above embodiment, the lumen of the tube 3 may be divided into an insertion passage through which the guide wire 4 is inserted and a flow passage through which a fluid such as water or air is passed.

[0060]

As described above, the present invention removes the outer peripheral edge portion around the narrow communication hole of the anastomotic part or narrowed part of the subject, and physically expands this narrow communication hole, It is possible to reduce or eliminate the anastomosis part and the stenosis part.
