Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a tubular intestinal anastomosis device for gastrointestinal surgery. Background Technology

[0002] An intestinal anastomosis device is a medical instrument used in surgery to connect the severed ends of the intestine. It replaces traditional manual suturing with mechanical methods, offering advantages such as ease of operation and rapid postoperative recovery. Its core principle involves two rows of metal staples (usually titanium alloy) arranged in a crisscross pattern, simultaneously cutting tissue and completing the staplement. Its design mimics the "inversion" or "exversion" effect of manual suturing, ensuring a tight fit between the two ends of the intestine and promoting healing.

[0003] For example, Chinese patent CN222237738U discloses an intestinal anastomosis device. In use, a biodegradable layer and a heat-insulating layer encapsulate the entire shape memory alloy, giving the anastomosis a U-shaped annular structure. The biodegradable layer slowly degrades naturally within the intestines, completing the degradation process after complete intestinal healing. The shape memory alloy then comes into contact with intestinal substances, causing its temperature to rise and its shape to change, forming a spherical structure that facilitates excretion.

[0004] While existing intestinal anastomosis devices can improve the accuracy of intestinal anastomosis to some extent, in actual operation, the use of shape memory alloys can reduce the difficulty of expulsion. However, due to intestinal peristalsis, the position of the shape memory alloy will shift with the peristalsis, which can easily cause separation between the two groups of intestinal segments, thus affecting the accuracy of intestinal anastomosis. Summary of the Invention

[0017] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0018] In the above scheme, by setting the anastomosis component, the first clamp and the second clamp will fit more tightly under the action of thrust. The two ends of the intestine are anastomosed by the first clamp and the anastomosis staples are used to fix and limit the first clamp and the second clamp, so that the first clamp and the second clamp can maintain a stable clamping state, thereby achieving rapid anastomosis of the intestine. At the same time, it can also reduce the risk of the first clamp and the second clamp shifting due to intestinal peristalsis to a certain extent, thus effectively improving the convenience and flexibility of intestinal anastomosis operation.

[0019] By setting up a suction component, the connecting seat 2, together with the compression plate, will pull the capsule. The blood generated during the intestinal anastomosis process will be suctioned into the capsule through the suction tube, thereby reducing the amount of blood residue in the intestine to a certain extent. This not only improves the cleanliness of the wound to a certain extent, but also further reduces the risk of infection at the intestinal anastomosis site, thus effectively improving the safety of the intestinal anastomosis device during use.

[0020] By incorporating a lubrication component, the absorbent cotton can absorb and transfer the lubricant. The ball will come into contact with the inside of the intestine, and the rotation of the ball can evenly spread the lubricant to the intestinal wall. This not only reduces the resistance during catheter insertion to a certain extent, but also reduces damage to the intestinal mucosa to a certain extent, thereby further improving the safety of intestinal anastomosis device operation.

[0039] like Figures 1 to 9 As shown, this embodiment of the invention provides a tubular intestinal anastomosis device for gastrointestinal surgery, including a body 11, a base 14, and a cannula 13. A conduit 15 is fixedly connected to the outer surface of the right end of the base 14. A rotating seat 20 is fixedly connected to the inner side of the conduit 15. A drive rod 19 is rotatably connected to the inner surface of the rotating seat 20. An anastomosis assembly is provided on the outer side of the drive rod 19. The anastomosis assembly includes an adjusting rod 23 threadedly connected to the right side of the drive rod 19. A connecting seat 17 is fixedly connected to the right end of the adjusting rod 23. A connecting seat 22 is fixedly and slidably connected to the inner surface of the body 11. A slot 43 is embedded in the outer surface of the right end of the connecting seat 17. A clamping plate 41 is slidably connected to the inner side of the slot 43. A clamping plate 53 is provided on the outer surface of the left end of the connecting seat 17. A top plate 45 is slidably connected to the inner side of the slot 43. An anastomosis staple 46 is fixedly connected to the outer surface of the top plate 45.

[0040] like Figure 4As shown, a baffle 21 is fixedly connected to the inner surface of the conduit 15, a magnetic plate 35 is fixedly connected to the outer surface of the baffle 21, a magnetic plate 34 is fixedly connected to the outer surface of the left end of the connecting seat 22, the clamp 41 and the clamp 53 are both annular, the number of anastomotic staples 46 is several groups and they are distributed in a ring array, and the sleeve 13 is fixedly connected to the outer surface of the machine base 14 and the machine body 11 respectively.

[0041] like Figure 1 and Figure 3 As shown, a switch 12 is provided on the upper side of the outer surface of the body 11. The switch 12 is electrically connected to the motor 18. The motor 18 is fixedly connected to the inner surface of the sleeve 13. The right end of the output shaft of the motor 18 is fixedly connected to the drive rod 19. The conduit 15 is made of elastic material. A folding groove 16 is embedded in the outer surface of the conduit 15. The number of folding grooves 16 is several groups and they are distributed in a parallel array.

[0042] By adopting the above technical solution, when using the anastomosis device, firstly, the second clamp 53 is sutured to one end of the intestine 70. At this time, the first connecting seat 17 is located inside the intestine 70, while the adjusting rod 23 protrudes to the outside of the intestine 70. Then, the operator inserts the catheter 15 into the patient's rectum through the anus via the machine body 11. When the catheter 15 moves to the anastomosis site of the intestine 70, the first clamp 41 is sutured to the other end of the intestine 70 to be anastomosed. The machine base 14 is used to fix and support the catheter 15 and the cannula 13 respectively. Then, the adjusting rod 23 is placed at the right end of the drive rod 19, and then the motor 18 inside the cannula 13 is started. The motor 18 drives the drive rod 19 to rotate synchronously. The drive rod 19 and the adjusting rod 23 are connected by a screw drive. As the drive rod 19 rotates, it will drive the adjusting rod 23 to move closer to the motor 18. During the movement, the adjusting rod 23 pulls the second clamp 53 through the first connecting seat 17. At this time, the second clamp 53 cooperates with the clamp. The plate pulls the two ends of the intestine 70 to make them contact each other. The catheter 15 is fixed and supported by the baffle 21 for the magnetic plate 35. Then, the magnetic plate 34 and the magnetic plate 35 are made conductive and their magnetic forces are opposite. At this time, the magnetic plate 34 pushes the connecting seat 22 to slide inside the catheter 15 under the magnetic repulsion of the magnetic plate 35. The clamp 41 and the clamp 53 will fit more tightly under the pushing force. The two ends of the intestine 70 are anastomosed by the clamp 41 and the clamp 53. The clamp 41 and the clamp 53 are fixed and limited by the anastomosis staple 46, so that the clamp 41 and the clamp 53 can maintain a stable clamping state. This enables the rapid anastomosis of the intestine 70 and reduces the risk of the clamp 41 and the clamp 53 shifting due to the peristalsis of the intestine 70. This effectively improves the convenience and flexibility of the intestinal anastomosis operation.

[0043] Specifically, such as Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, a release assembly is provided on the outer side of the adjusting rod 23. The release assembly includes a sliding groove 48 embedded in the inner side of the adjusting rod 23. There are two sets of sliding grooves 48, which are symmetrically distributed. A sliding plate 51 is slidably connected to the inner side of the sliding groove 48. A pressing block 50 is fixedly connected to the outer surface of the sliding plate 51. The outer surface of the pressing block 50 is arc-shaped. An elastic plate 49 is fixedly connected to the outer surface of the sliding plate 51 away from the pressing block 50. The elastic plate 49 has a U-shaped structure. A top rod 52 is fixedly connected to the outer surface of the sliding plate 51. The end of the top rod 52 away from the sliding plate 51 is engaged with the clamping plate 53.

[0044] like Figure 6 and Figure 8 As shown, a slot 43 is embedded in the outer surface of the right end of the connecting seat 17. A spring 44 is fixedly connected to the inner surface of the slot 43. The spring 44 is fixedly connected to the outer surface of the top plate 45. A placement groove 59 is embedded in the inner side of the slot 43. A pin 33 is fixedly connected to the inner surface of the placement groove 59. A limiting plate 40 is rotatably connected to the outer surface of the pin 33. A traction belt 60 is fixedly connected to the lower outer surface of the limiting plate 40. A push rod 58 is fixedly connected to the end of the traction belt 60 away from the limiting plate 40. The push rod 58 passes through to the outside of the slot 43 and is slidably connected to the connecting seat 22. The end of the limiting plate 40 away from the pin 33 is in sliding contact with the outer surface of the top plate 45. An installation sleeve 42 is fixedly connected to the inner surface of the slot 43. The installation sleeve 42 is engaged with the outer surface of the clamping plate 41.

[0045] like Figure 7 As shown, a locking assembly is provided on the outer side of the anastomosis staple 46. The locking assembly includes a limiting hole 54 opened on the outer surface of the clamping plate 2 53. A storage groove 55 is embedded in the inner side of the connecting seat 17. A spring 2 57 is fixedly connected to the inner surface of the storage groove 55. A limiting block 56 is fixedly connected to the side of the spring 2 57 away from the storage groove 55. The outer surface of the limiting block 56 is arc-shaped. A limiting groove 47 is embedded in the outer surface of the anastomosis staple 46.

[0046] By adopting the above technical solution, after clamp 1 41 and clamp 2 53 pull the intestine 70 to anastomose, clamp 1 41 and clamp 2 53 are released by the release component, so that clamp 1 41 and clamp 2 53 can continuously clamp the intestine 70. During operation, during the process of clamp 1 41 and clamp 2 53 fitting together, clamp 2 53 will push clamp 1 41 to slide into the groove 43. During the movement, clamp 1 41 will contact push rod 58 and push push rod 58 to move into the placement groove 59. The placement groove 59 supports the rotation of the limiting plate 40 through the pin 33. The upper end of the limiting plate 40 contacts the outer surface of the top plate 45 to limit the top plate 45. During the movement, push rod 58 will pull the traction belt 60. Under the pull of the traction belt 60, the limiting plate 40 will flip downward with the pin 33 as the fulcrum, so that the limiting plate 40 flips into the placement groove 59. After the limiting plate 40 disengages from the outer surface of the top plate 45, the top plate 45 slides outward along the inside of the groove 43 under the elastic force of the spring 44. The movement of the top plate 45 can drive the anastomosis staple 46 to move synchronously, so that the anastomosis staple 46 pierces into the limiting hole 54 on the surface of the clamp 53. The anastomosis staple 46 can lock and fix the clamp 41 and the clamp 53, thereby making the anastomosis of the intestine 70 tighter and further improving the anastomosis accuracy of the intestine 70. When the anastomosis staple 46 moves into the limiting hole 54, the limiting block 56 inside the receiving groove 55 is engaged in the limiting groove 47 on the surface of the anastomosis staple 46 under the elastic force of the spring 57. The limiting block 56 and the limiting groove 47 can lock and fix the anastomosis staple 46, thereby effectively improving the anastomosis accuracy of the anastomosis staple 46 and effectively reducing the probability of the anastomosis staple 46 loosening and falling off.

[0047] When connecting seat 17 and connecting seat 22 approach each other, the right end of the drive rod 19 will contact the outer surface of the extrusion block 50. At this time, under pressure, the extrusion block 50 will push the slide plate 51 to slide inside the slide groove 48. While the slide plate 51 extrudes the elastic plate 49, it will also pull the push rod 52, causing the push rod 52 to disengage from the surface of the clamping plate 2 53. This will allow the clamping plate 2 53 to disengage from the outer surface of connecting seat 17, thereby enabling the clamping plate 2 53 to be accurately released from connecting seat 17. This will help to further improve the operational flexibility and practicality during the intestinal anastomosis process.

[0048] Specifically, such as Figure 4 and Figure 6As shown, a suction component is provided inside the connecting seat 22. The suction component includes a cavity 36 embedded inside the connecting seat 22. A squeezing plate 37 is slidably connected to the inner surface of the cavity 36. A bladder 38 is fixedly connected to the outer surface of the squeezing plate 37. The outer surface of the bladder 38 away from the squeezing plate 37 is fixedly connected to the inner wall of the cavity 36. A suction tube 39 is embedded and fixedly connected inside the connecting seat 22. The suction tube 39 extends to the outer side of the connecting seat 22. The bladder 38 is distributed in a ring shape.

[0049] like Figure 6 As shown, a movable sleeve 30 is fixedly connected to the outer surface of the right end of the baffle 21, a piston plate 31 is slidably connected to the inner surface of the movable sleeve 30, a movable rod 32 is fixedly connected to the outer surface of the piston plate 31, the movable rod 32 passes through the inner side of the cavity 36 and is fixedly connected to the outer surface of the extrusion plate 37, and the number of suction tubes 39 is several groups and they are distributed in a ring array.

[0050] By adopting the above technical solution, when the second connecting seat 22 moves to the side of the first connecting seat 17 under the action of magnetic force, the bladder 38 and the compression plate 37 inside the cavity 36 will move synchronously with the second connecting seat 22. The compression plate 37 drives the piston plate 31 to slide inside the movable sleeve 30 through the movable rod 32. When the piston plate 31 moves to the rightmost side inside the movable sleeve 30, the piston plate 31 and the movable rod 32 will stop moving. At this time, as the second connecting seat 22 continues to move, the second connecting seat 22, together with the compression plate 37, will pull the bladder 38. As the volume of the bladder 38 gradually increases, a certain negative pressure will be formed inside the bladder 38. At this time, the blood generated during the anastomosis of the intestine 70 will be sucked into the bladder 38 through the suction tube 39, thereby reducing the residual blood inside the intestine 70 to a certain extent. This not only improves the cleanliness of the wound to a certain extent, but also further reduces the risk of infection at the anastomosis site of the intestine 70, thereby effectively improving the safety of the intestinal anastomosis device during use.

[0051] Specifically, such as Figure 4 and Figure 5As shown, a lubrication assembly is provided on the outer side of the conduit 15. The lubrication assembly includes a liquid storage chamber 24 embedded inside the conduit 15. A compression sleeve 26 is fixedly connected to the outer surface of the conduit 15. Both the liquid storage chamber 24 and the compression sleeve 26 are annular. The compression sleeve 26 is made of elastic material. An inlet pipe 27 is fixedly connected to the outer surface of the compression sleeve 26. A guide groove 28 is embedded inside the conduit 15. A ball bearing 29 is rotatably connected inside the guide groove 28. The ball bearing 29 extends to the outer side of the guide groove 28. The ball bearing 29 is in several groups and arranged in a ring array. An absorbent cotton 25 is fixedly connected inside the liquid storage chamber 24. The absorbent cotton 25 extends into the guide groove 28 and rotates in contact with the ball bearing 29. The ball bearing 29 is made of elastic material.

[0052] By adopting the above technical solution, before the stapler is used, an appropriate amount of lubricant is first injected into the reservoir 24 through the inlet tube 27. The absorbent cotton 25 can absorb and transfer the lubricant. When the catheter 15 moves inside the intestine 70, the inner wall of the intestine 70 will contact the outer surface of the compression sleeve 26. Under the pressure of the inner wall of the intestine 70, the compression sleeve 26 will undergo elastic deformation, which can accelerate the transfer of lubricant to the absorbent cotton 25. After the lubricant is transferred to the ball bearings 29 through the absorbent cotton 25, when the catheter 15 moves inside the intestine 70, several sets of ball bearings 29 will contact the inside of the intestine 70. The rotation of the ball bearings 29 can evenly coat the lubricant onto the inner wall of the intestine 70. This can not only reduce the resistance during the insertion of the catheter 15 to a certain extent, but also reduce the damage to the mucosa of the intestine 70 to a certain extent, thereby further improving the safety of the intestinal stapler operation.

[0053] The workflow of the technical solution of this invention is as follows:

[0054] Before use, the anastomosis device first injects an appropriate amount of lubricant into the reservoir 24 through the inlet tube 27. The absorbent cotton 25 absorbs and transfers the lubricant. Then, the second clamp 53 is sutured to one end of the intestine 70. The operator inserts the catheter 15 into the patient's rectum through the body 11. The ball bearing 29 contacts the inside of the intestine 70. The rotation of the ball bearing 29 can evenly spread the lubricant to the inner wall of the intestine 70, which can reduce the resistance during the insertion of the catheter 15 to a certain extent. When the catheter 15 moves to the anastomosis site of the intestine 70, the first clamp 41 is sutured to the other end of the intestine 70 to be anastomosed. During the movement, the adjusting rod 23 pulls the second clamp 53 through the connecting seat 17. At this time, the second clamp 53, together with the clamp, pulls the two ends of the intestine 70, so that the two ends of the intestine 70 come into contact. The movement of the top plate 45 can drive the anastomosis staples 46 to move synchronously. This allows the anastomotic staple 46 to pierce into the limiting hole 54 on the surface of the second splint 53. The anastomotic staple 46 can lock and fix the first splint 41 and the second splint 53, thereby making the anastomosis of the intestine 70 tighter. While the sliding plate 51 squeezes the elastic plate 49, it also pulls the push rod 52, causing the push rod 52 to disengage from the surface of the second splint 53. This allows the second splint 53 to disengage from the outer surface of the first connecting seat 17, thus enabling the precise release of the second splint 53 and the first connecting seat 17. As the second connecting seat 22 continues to move, the second connecting seat 22, together with the squeezing plate 37, will pull the cyst 38. As the volume of the cyst 38 gradually increases, a certain negative pressure will be formed inside the cyst 38. At this time, the blood generated during the anastomosis of the intestine 70 will be sucked into the cyst 38 through the suction tube 39, thereby reducing the amount of blood residue inside the intestine 70 to a certain extent.
