Description

N / 29257-Fa / vdM ^ ^

Anton Jansen in Amsterdam, the Netherlands.

Medical device for coupling two intestinal sections, auxiliary device for use therewith and method for making a gut knot with the aid of this device.

The invention relates to a medical device for coupling two intestinal parts, consisting of two parts to be coupled to each other, which are intended for insertion into the respective ends of the two intestinal parts and between which these intestinal ends can be clamped, which parts to be coupled provided with coupling members, comprising an outwardly protruding pin connected to one part, which fits into a continuous central opening and holding members arranged in the other part, whereby the second part can be pressed against the first part, as well as on an auxiliary device for use therewith and on a method of making an intestinal knot with the aid of this device.

A device of the above-described type is known from. United States Patent 2,434,030. In the device described in this patent, the connection between the two parts of the gut node can only be established and maintained by manipulating the part of one part protruding outside the patient's body. This limits the use of this known construction to rectal colon anastomosis. Furthermore, this device has the drawback that parts of the device remain protruded outside the body during reconvalescence, as a result of which there is a risk of damage to the still vulnerable intestinal part. Furthermore, the device must be adjusted to the feeling and adjusted.

Dutch patent 82,213 proposes an improvement of this device, which also includes 7906691; 2 operations other than rectal colon anastomoses can be performed. In fact, however, the device described there is particularly suitable for coupling intestinal portions of the esophagus, but provides little benefit in laying gut seams in rectal colon anastomosis. .

The object of the invention is now to provide a gut node of the aforementioned type which can be used universally for all kinds of gut seams, which is extremely easy to apply, which is extremely light and which can easily leave the body and furthermore a good healing of intestine.

Accordingly, the invention provides a medical device of the type indicated, characterized in that the outwardly protruding pin on one part is internally hollow with an internal dimension which is at least 1/3 of the outer dimension of the one part, this cavity extends through the entire part and the pin has a sliding fit on the central opening in the other part, while the retaining members consist of magnets in mutually facing sections of the coupling parts, in addition to the outwardly projecting pin in one and next to the central opening in the other part.

Although the cross section profile of the coupling parts is not essential due to the pliability of the intestinal wall, it is evidently advantageous, from the viewpoint of both manufacturing and technical aspects, to make the coupling parts rotationally symmetrical. More particularly, manipulation of the two coupling parts in the intestinal ends is facilitated when the two coupling parts are rings with a cylindrical outer surface and the same ring diameter. In addition, the manufacture of the device becomes simple when the magnets in the coupling parts are ring magnets with an outer diameter equal to or less than the coupling part jacket diameter and an inner diameter larger than the largest pin diameter.

7906691 * »3

The thickness of the ring magnets does not have to be the same as the thickness of the ring. Because the magnet must be as close as possible to the facing surfaces of the two annular coupling parts to be mutually reciprocated in order to exert its effect, and only that part which is located close to the front surface substantially contributes to the closing force of the device, the thickness of the coupling parts is greater than the thickness of the area provided with magnet material.

In order to prevent tilting during manipulation, the jacket thickness of the coupling parts is even preferably considerably greater than the thickness of the magnetic ring. However, in order to prevent tissue residues, waste materials and the like from accumulating between the intestinal wall and the jacket surface of the coupling parts, it is advantageous if openings are recessed in the magnet-free part of the jacket of the coupling parts remote from the end surfaces. .

In addition, these openings still contribute to weight reduction, which is important, because pressure of the weight of the device can lead to damage (lying through) during reconvalescence.

In order to promote good wound healing, it can be harmful if the gut knot can be twisted. Therefore, in a preferred embodiment of the invention, the protruding pin on the outside of one coupling part is provided with a profile such that this pin can be received in the central opening of the other coupling part and this other coupling part can slide over the pin without rotation on its axis. In particular, the outer profile cross-section of the protruding pin on the one coupling part and the inner profile cross-section of the central opening in the other coupling part have the hexagon shape, the first being slightly smaller than the second. The hexagon has manufacturing advantages, but shapes of other polygons or slots, ribs and the like can of course also be used, although as a rule they are more laborious of 7906691 V * 4 nature.

The two coupling parts each have to be slid into an intestinal end during the operation, after which the end of the intestine is closed with a surgical "purse seam" up to a communication opening. This communication opening must be large enough for the protruding pin to pass through. For the part provided with the protruding pin this also prevents the coupling part from tilting, but for the coupling part which only has the central opening, tilting after applying the "exhibition seam" is by no means excluded. Therefore, in another preferred embodiment of the invention, at a short distance from the circumference, perpendicular to the end face of the other coupling part, pointed pins are received with corresponding recesses for receiving the nib tips in the end face of the one part. Also in one part such pins can be arranged, which promote the impeccable closing of the seam and make it possible to attach the two intestinal ends by hand after closing the coupling device.

The body of the coupling parts can be made of any raw material which is inert in the body and does not give rise to tissue reactions. However, the coupling parts are intended to remain in the body only temporarily, and after healing of the wound (death of the tissue sandwiched between the rings takes place), the coupling device releases from the intestinal wall and is naturally excreted with the faeces. .

A suitable material for the body of the coupling parts is an inert plastic, which is extrudable.

A suitable plastic is, for example, a polyester-polyethylene terephthalate.

The magnets are preferably made of polymer-bonded rare earth cobalt alloys, because these materials can be easily machined in unmagnetized state 7906691 * 5.

The device according to the invention is, due to its simplicity of construction and due to its low weight, extremely suitable for making flawless gut seams, while the danger of post-operative complications has also been considerably reduced. The device can be used in all places in the human body where intestinal resections are necessary, such as in the esophagus, the small intestine, the colon and the colon.

Colon-intestinal resections are among the most difficult interventions, however, because the colon often only has a short stump, which is hidden deep in the abdominal cavity. Manipulation there on the spot is difficult. The invention therefore provides an auxiliary device for this type of operation, whereby colonic anastomoses can be facilitated. This auxiliary device consists of a lifting pin with a handle on one end and a seat knob on the other end, fitting on the lower part of the coupling part provided only with a central opening, as well as a rounded part on the top, also on the jacket circumference of the coupling part connecting button with fasteners to the seat button.

To perform a colon anastomosis, the seat knob is screwed onto the lifting pin with handle, the seat bottom part of the coupling part with only a central opening is inserted and the head surface of this coupling part is closed by attaching the rounded button on top and attaching it to the seat button. This results in a smoothly formed whole, which is inserted rectally into the colon stump with the lifting pin, until the rounded bud emerges on the ventral side. Then the coupling between the rounded knob and the seat knob is loosened from the outside and the rounded knob is removed. Preferably, then, a further auxiliary device, consisting of an extension rod for the protruding pin on the one coupling part with the same outer profile cross section, which can be inserted into the pin opening with a locking device for fixing the correct position of the profiles with respect to each other, inserted into the released central opening of the coupling part and fastened from the outside to the seat knob. Then the purse seam applied around the intestinal end is pulled until the intestinal end connects to the extension rod, which now protrudes upwards into the abdominal cavity. With the lifting pin the coupling part is now pushed upwards, so that it becomes more accessible for the operator, who now brings the coupling part already arranged in the other intestinal end with the protruding pin by hand to the protruding end of the extension rod and into the correct position the protruding pin 15 protrudes on the extension rod. While the operator now holds one gut end with one hand and the other gut end with the other hand, the assistant slowly pulls the lift pin with the attached seat button and attached extension rod down and out of the patient's body. both coupling parts approach each other without rotation relative to each other being possible. In the end, only the two coupling parts remain in the body, with the constricted ends of the intestine clamped between them.

The invention also comprises a method for laying an intestinal seam with the aid of a device according to the invention, characterized in that after resection of the intestine, the mucosa and submucosa are separated from the enveloping muscle layer, which is prepared over a few 30 millimeters after which the two coupling parts are placed in the intestinal ends and only the mucosa and submucosa layers are clamped between the two coupling parts.

The invention will now be further elucidated on the basis of a preferred embodiment of the invention shown in the accompanying drawings.

Figure 6 is a top view of the auxiliary device as in Figure 5 after inserting the coupling part with protruding pin on the end of the extension rod fitting in the pin.

Figure 7 is a top plan view of the auxiliary device as in Figure 6 after the withdrawal of the auxiliary device has started.

Figure 8 is a top plan view of the auxiliary device as shown in Figure 7 upon completion of the retraction, and Figures 9 through 16 show stages in performing colon surgery using the features shown in Figures 1 through 8 device shown.

The intestinal node according to the invention shown in Figures 1-3 consists of a coupling part 1 with a protruding pin 2 / fitting in a central opening 3 of the other coupling part 4. The open position of the device, shown in Figures 3a and 3b, shows the location of the ring magnets 5 and 6 on the end faces 7 and 8. In addition to the magnet rings, pointed pins 9, 10 and openings 11, 12 are provided in the end faces 7 and 8, the openings 35 serving in one part for recording the protruding 79 0 6 6 9 tr% 8 pointed pins of the other part and vice versa. Figure 3 further clearly shows the hexagonal shape of the protruding pin 2 and the internal hexagonal shape of the central opening 3 of the one coupling part and the other, respectively. In the part of the jacket 13, 14 of the coupling parts 1, 4, which is free of magnetic material, openings 15, 16 are provided, which have a twofold purpose. In the first place, they serve for the removal of waste material, which can be located between the intestinal wall and the device, and in the second place, the openings provided give a desired weight saving. After all, for good healing it is very important that as little pressure as possible is exerted on the healing intestinal part. A drawback of the intestinal nodes used so far was in particular their relatively considerable weight, which frequently gave rise to intestinal damage as a result of bedsores. The light weight of the magnetic closure device added when the lateral openings 15, 16 are provided in the jackets 13, 14 of the coupling parts 1, 4 provides an extremely light device, which is excellently tolerated.

The auxiliary device for the application of the intestinal knot according to Figures 1-3 in colon anastomoses is shown in Figures 4 to 8. Figure 4 shows the lifting pin 17 with the seat button 25 18 screwed thereon, which on top seat 19 (see fig. 7 or 8) on which the coupling part 4 rests with its magnet-free casing part 14. The end face 8 (fig. 3a) with the pins 10 is closed by the rounded knob 20, which is screwed onto the seat knob 18.

After insertion into the patient's body, the knob 20 is unscrewed and removed. Instead, the extension rod 21 is screwed with the threaded pin end in place of the rounded knob 20. Then the condition is reached as shown in figure 5. The free end 22 of the rod 21 is round and 7906691 9 has a diameter which is just slightly smaller than the internal diameter of the bore through the protruding pin 2 of the one coupling part 1. At the transition of the round rod piece 22 into the hexagonal part of the rod 21, an ar-5 retaining rod 23 is provided, which fits on corresponding recesses 24 arranged in the protruding end of the pin 2 (fig. 3b , 6).

Figure 6 shows the state that is reached after the protruding pin 2 of the coupling part 1 is put on the rod end 22. The correct position of the coupling part 1 can be adjusted by means of the adjustable locking device 23, 24. . Subsequently, by lowering the coupling part 1, the pin 21 is slid through the central opening 3 in the coupling part 4 (fig. 7), after which the coupling part 4 finally reaches the protruding pin 2 of part 1 and slides over this pin until coupling of both parts is reached by the magnetic force (fig. 8).

The method for arranging the intestinal knot 1, 4 according to the invention is further elucidated by figures 9 to 16.

Figure 9 shows a cross section of the rectum 25 and the colon 26, in which a proliferation 27 has occurred. The intestine is cut at the locations of the dotted lines 28 and 29. The intermediate affected intestinal section 27 is removed. From the protruding end 30 of the colon stump, the muscle layer is loosened and prepared over a distance of a few millimeters, so that only mucosar submucosa layers 31 protrude at that end 30.

Figure 10 shows how the lifting pin 17 with seat button 18, coupling part 4 with casing part 14 connecting to the seat button 18 and rounded button 20 (see figure 4) by means of the handle 32 via the rectum to the end 31 of the colon stump is being brought.

Figure 11 shows how a surgical purse seam has already been applied around this intestinal end of the colon stump 3190669t. The rounded knob 20 is then unscrewed and removed, resulting in the situation shown in figure 1. Now, as indicated, the extension 5 rod 21 with the threaded pin end is inserted down into the central opening 3 of the coupling part 4 open with its head face 8 and is fixed in the seat knob 18 by turning the lifting pin 17. .

As indicated in Figure 12, the purse-10 seam 32 is then closed and the coupling part 4 is pressed up on the seat knob 18 by means of the discharge pin 17, so that the pins 10 are pressed through the mucosa and submucosa layers and the colon stump is tight is pulled up. The extension rod 21 now becomes an easily accessible point with its free end 22.

In the other intestinal end 33 with the freely prepared mucosa and submucosa layers 34, provided with the purse seam 35, the coupling part 1 with the protruding pin 2 is now inserted, after which the purse seam 35 is tightened and secured. The pins 11 then protrude through the mucosa and submucosa layers.

Then, as shown in Figure 13, the protruding pin 2 of the coupling part 1 introduced into the intestine 33 is brought to the end 22 of the extension rod 21 and slid into it in the correct position. The detent device 23, 24 ensures that the position once selected with respect to the intestinal part 30 is maintained.

Then the intestinal end 33 is pushed down manually, while at the same time the lifting pin 17 with the parts 18 and 21 attached thereto is pulled out of the body.

As shown in figure 14, the coupling parts 1 and 4 approach each other with the intestinal ends 34, 31 folded over the end faces. Due to the magnetic attraction, the device then closes automatically by clamping the two mucosa ends of the intestine. The pressure of the magnetic force 7906691 11 ensures a water and airtight seal.

As shown in Figure 15, the head 22 of the extension rod 21 is now detached from the protruding pin 2 of the coupling part 1r. which is now firmly connected to the coupling part 4. The gut seam can now be completed with some sutures on the outside, as indicated in figures 15 and 16.

Figure 16 shows the finally completed gut seam.
