Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a magnetic intestinal stapler. Background Art

[0002] The tubular intestinal stapler is a surgical instrument mainly used for anastomosis of the intestine or other pipes during digestive tract surgery. It connects the ends of the intestine with titanium nails. Among the more cutting-edge technologies, there is a technology that achieves intestinal anastomosis through magnetic action, namely the magnetic intestinal stapler. It does not rely on traditional mechanical sutures or metal nails, but uses the attraction between two magnetic rings to fit the two sections of the intestine that need to be anastomosed and promote natural healing of the tissue. During the intestinal anastomosis operation, the doctor needs to insert part of the tissue at the end of the intestine into the inside of the magnetic ring, and then bring the two magnetic rings closer to attract. In about two weeks, the end of the intestine where the magnetic ring is located will heal naturally, while the intestinal tissue inside the magnetic ring will necrotize and fall off, and finally be discharged from the body by the patient along with the magnetic ring.

[0003] When inserting part of the tissue at the end of the intestine into the inside of the magnetic ring, the doctor usually needs to manually use surgical forceps to complete this step, which is a great test of the doctor's skills and patience. The smooth substances such as oil and mucus inside the intestine can easily cause the magnetic ring to move, and then the magnetic ring needs to be repositioned, resulting in reduced efficiency of the operation.

This embodiment is different from the first embodiment in that the adjustment mechanism 5 includes a sliding cylinder 501, an adjusting screw cylinder 502, an extrusion ring 503, a plastic spring 504 and a top ball 505. The sliding cylinder 501 is slidably arranged on the outside of the long cylinder 4. A threaded groove is provided on the side surface of one end of the sliding cylinder 501. The adjusting screw cylinder 502 is sleeved on the side surface of the sliding cylinder 501 and is threadedly connected to the threaded groove.

[0039] The extrusion ring 503 is sleeved and slidably arranged on the outside of the sliding cylinder 501, and one end of the extrusion ring 503 is rotatably arranged on the end of the adjusting screw cylinder 502. A plurality of plastic spring pieces 504 are arranged and evenly surround the end of the sliding cylinder 501 close to the extrusion ring 503.

There are multiple rotating rods 602 that are evenly surrounded by the outer side of the adjusting rod 601.

[0042] The slide rail 603 is fixedly arranged on one side of the rotating rod 602 close to the plastic spring 504, one end of the sliding rod 604 is fixedly arranged on the inner side of the long tube 4, and the other end is slidably arranged on the inner side of the slide rail 603, and the side hole 605 is opened on the side of the long tube 4, and the position of the side hole 605 is opposite to the rotating rod 602. The baffle 606 is located on the side of the rotating rod 602 close to the slide rail 603 and is fixedly arranged on the side of the adjusting rod 601.

[0043] The fixing groove 607 is L-shaped and is opened on the inner side of the housing 2. The number of the fixing grooves 607 corresponds to the number of the rotating rods 602. When the end of the rotating rod 602 away from the adjusting rod 601 is slidably disposed on the inner side of the fixing groove 607, the magnetic ring 1 is in a fixed state.

[0044] The inflation mechanism 7 includes an extrusion spring piece 701, an extrusion airbag 702, an inflation tube 703, an air leakage hole 704, an inflation airbag 705, a rubber pad 706 and a one-way valve 707. A plurality of extrusion spring pieces 701 are provided and fixedly arranged at one end of the long tube 4 close to the magnetic ring 1. The extrusion spring piece 701 is made of plastic and has elasticity. In a natural state, the extrusion spring piece 701 bounces toward the center of the long tube 4. The extrusion airbag 702 is located on the inner side of the extrusion spring piece 701 and is fixedly arranged at the end of the long tube 4. The side of the extrusion spring piece 701 abuts against the outer side of the extrusion airbag 702.

[0045] The inflation tube 703 is located between the adjusting rod 601 and the inner wall of the long tube 4, one end of the inflation tube 703 is connected to the extrusion airbag 702, and the other end passes through the outside of the long tube 4, the leakage hole 704 is opened on the outside of the inflation tube 703 at one end outside the long tube 4, the rubber pad 706 is fixedly arranged on the inner side of the air outlet of the inflation airbag 705, the inflation airbag 705 is slidably arranged on the end of the inflation tube 703 close to the leakage hole 704 through the rubber pad 706, and the one-way valve 707 is fixedly arranged on the inner side of the air outlet of the inflation airbag 705.

[0046] Compared with conventional magnetic staplers, the present invention is equipped with a special device to help doctors fit part of the patient's intestinal tissue tightly against the inner side of the magnetic ring 1. In actual use, the magnetic ring 1 needs to be fixed on the outer side of the long tube 4 first.

[0047] First, the entire device is disinfected, and then the medical staff puts the magnetic ring 1 on the outside of the long tube 4 from the end of the long tube 4 close to the squeezing airbag 702 (at this time, the squeezing airbag 702 is not in an inflated state and is squeezed by the squeezing shrapnel 701, so it can be easily passed by the magnetic ring 1), and then moves the magnetic ring 1 to the vicinity of the rotating rod 602. After completing the above steps, the adjustment rod 601 is moved toward the side close to the squeezing airbag 702. As the adjustment rod 601 slides, the rotating rod 602 moves synchronously, and when the sliding rod 604 slides on the inner side of the slide rail 603, the rotating rod 602 is rotated out of the side hole 605 due to the sliding of the sliding rod 604, and finally abuts against the side of the baffle 606 as the adjustment rod 601 slides, and the axis of the rotating rod 602 and the axis of the adjustment rod 601 are at 90 degrees. Then the medical staff slides the ends of the rotating rods 602 from the ends of the outer shell 2 into the fixing grooves 607, and then rotates them at a certain angle so that the rotating rods 602 slide into the inner side of the fixing grooves 607, thereby fixing the connecting magnetic ring 1 and the outer shell 2 to the outer side of the long tube 4. To separate the magnetic ring 1 and the long tube 4, the doctor only needs to fix the magnetic ring 1 on the outer side of the intestine, rotate the long tube 4 in the opposite direction and move the rotating rods 602 out of the fixing grooves 607, and finally pull the adjusting rod 601 in the opposite direction so that the rotating rods 602 are rotated into the interior of the long tube 4.

[0048] After being fixed, the axis of the magnetic ring 1 and the axis of the long tube 4 remain parallel, so the doctor can hold the long tube 4 to send the magnetic ring 1 into the intestine, avoiding the problem of the magnetic ring 1 being difficult to operate due to its small size, thereby achieving the purpose of improving the efficiency of the operation.

[0049] After the magnetic ring 1 is fixed, the magnetic ring 1 and the long tube 4 are inserted into the intestine, and the tissue at the end of the intestine is put on the outside of the magnetic ring 1, and then the intestinal tissue of a suitable length is left to pass through the magnetic ring 1 to the inside of several plastic shrapnel 504. Then the doctor holds one end of the sliding tube 501 with one hand and rotates the adjusting screw 502 with the other hand. The squeezing ring 503 follows the adjusting screw 502 to move toward the plastic shrapnel 504, so that the plastic shrapnel 504 is squeezed toward the side close to the magnetic ring 1 and finally the top ball 505 is pressed against the surface of the intestine, and the intestinal epidermis is squeezed by the plastic shrapnel 504 and sticks to the surface of the long tube 4. Then the doctor holds the long tube 4 with one hand and moves the sliding tube 501 close to the magnetic ring 1 with the other hand. As the sliding tube 501 moves, the plastic shrapnel 504 folds the intestinal tissue into the inside of the magnetic ring 1.

[0050] The multiple plastic spring pieces 504 are squeezed by the squeezing ring 503 to clamp the intestine inside the shell 2, and the multiple plastic spring pieces 504 can fully clamp the surface of the intestine, so that the sliding cylinder 501 can drive the intestinal tissue to fold into the inside of the magnetic ring 1 at the same time when moving, and the top ball 505 not only has the effect of reducing the surface resistance of the intestine, so that the plastic spring pieces 504 can be smoothly pushed into the inside of the magnetic ring 1, but also can avoid the plastic spring pieces 504 from damaging the intestinal tissue. Compared with manually using surgical forceps to insert the intestine into the magnetic ring 1, the method of the present invention is faster and harmless.

[0051] After the intestinal tissue is folded into the inside of the magnetic ring 1, the magnetic ring 1 and the rotating rod 602 are separated, and then the doctor slides the air outlet of the inflatable airbag 705 along the inflation tube 703. At this time, the rubber pad 706 blocks the leakage hole 704, and then the inflatable airbag 705 is squeezed by hand. The gas in the inflatable airbag 705 enters the interior of the squeezing airbag 702 through the one-way valve 707 and the inflation tube 703, so that the squeezing airbag 702 expands and opens the squeezing spring 701, and the one-way valve 707 can prevent the gas inside the squeezing airbag 702 from flowing back.

[0052] When the squeezing balloon 702 is fully expanded, it will form a balloon with a diameter slightly smaller than that of the outer shell 2. The doctor then fixes the magnetic ring 1 outside the intestine and pulls the long tube 4 toward the outside of the intestine. The plastic spring 504 easily slides out of the magnetic ring 1 due to its elasticity, and the squeezing spring 701 and the squeezing balloon 702 together squeeze the intestinal tissue folded inside the magnetic ring 1 and the outer shell 2 toward the barb 3, so that this part of the intestinal tissue is hooked inside the barb 3. Since the magnetic ring 1 is in a fixed state, the doctor can directly overcome the surface elastic force of the squeezing balloon 702 and pull the squeezing balloon 702 out of the magnetic ring 1 and the inside of the intestine.

[0053] If the squeezing airbag 702 needs to be deflated, the inflatable airbag 705 can be slid down to expose the air leakage port, and the squeezing airbag 702 will be squeezed by the squeezing spring 701, causing the gas therein to escape from the air leakage port, thereby achieving the squeezing airbag 702 deflation.

[0054] Through the squeezing action of the inflation component, the intestinal tissue can be directly connected with the outer shell 2 and the magnetic ring 1, avoiding the separation of the intestine and the magnetic ring 1 after the operation. This part of the folded intestinal tissue itself will necrotize over time, so its destruction will not affect the rest of the intestinal tissue.

[0055] The remaining structures are the same as those of Example 1.
