Description

Technical Field

[0001] This invention belongs to the field of enterostomy fixation technology, specifically referring to a general surgical enterostomy fixation device. Background Technology

[0002] Enterostomy is a surgical procedure that connects the intestinal lumen to the abdominal wall. It is mainly used for intestinal nutritional support, fecal excretion, or intestinal decompression. This surgery is one of the important ways to treat colorectal cancer. It achieves intestinal decompression, obstruction relief, and replacement of defecation function by changing the patient's original excretion channel.

[0003] During enterostomy surgery, it is necessary to fix the connection between the intestinal cavity and the abdominal wall. The existing fixation method usually uses a plastic sealing cap to directly connect and fix the bag at the connection point. Generally, it is fixed by adhesive. This method is obviously not stable enough. On the other hand, it is difficult to avoid deformation of the connecting tube during the patient's movement, which can easily lead to damage to the connecting tube. Therefore, it is necessary to propose a general surgical enterostomy fixation device. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a general surgical enterostomy fixation device, which effectively solves the problem that existing general surgical enterostomy fixation devices are unable to simultaneously achieve all-round fixation and keep the connecting tube undamaged.

[0005] The technical solution adopted by this invention is as follows: This invention provides a general surgical enterostomy fixation device, including an automatic fixation device, a constraint clamping assembly, a drive motor, and a fixing base. The drive motor is mounted on the fixing base via a base. The constraint clamping assembly is arranged in two groups on the fixing base, and the constraint clamping assembly is connected to the drive motor via a transmission connection. The constraint clamping assembly is provided with a contact partition, and the automatic fixation device is arranged in a surrounding array on the contact partition. The two groups of constraint clamping assemblies achieve the effect of fixing and connecting the connecting tube from both sides for initial fixation, and then the automatic fixation device completely fixes the connecting tube, resulting in a better fixation effect.

[0006] Preferably, the automatic fixing device includes a symmetrical cylinder, a piston moving rod, a piston moving plate, a magnetorheological fluid, an electromagnet, a trigger button, and a docking cylinder. The docking cylinder is embedded in the contact partition, the electromagnet is located at the bottom of the docking cylinder, the symmetrical cylinder is divided into two groups connected on both sides of the docking cylinder, the piston moving plate is piston-slidably disposed in the symmetrical cylinder, the piston moving rod is disposed on the piston moving plate, the trigger button is disposed on the piston moving rod at the end away from the piston moving plate, and a fluid moving cavity is formed between the two groups of piston moving plates, in which the magnetorheological fluid flows.

[0007] Furthermore, the constraint clamping assembly includes a rotating base, a guide gear ring, a rotating gear, a rotating cylinder, a fixed side plate, a rotating arc plate, a protruding connecting plate, a transmission arc groove, a rotating connecting column, and a fixed rotating shaft. The rotating gear is connected to the output end of the drive motor. The rotating base is fixed to the fixed base. The guide gear ring is rotatably fitted onto the rotating base. The rotating cylinder is fixed to the inner wall of the guide gear ring. The fixed side plate is fixed to the fixed base. The fixed rotating shaft is located on the fixed side plate. The rotating connecting column is located on the rotating cylinder at the end away from the fixed side plate. The rotating arc plate is rotatably mounted on the fixed rotating shaft. The protruding connecting plate is located on the rotating arc plate. The transmission arc groove is located on the protruding connecting plate. The rotating connecting column is slidably fitted into the transmission arc groove. The protruding connecting plate has a notch for the fixed rotating shaft to pass through without interfering with the rotation of the protruding connecting plate.

[0008] The contact partition is fixed to the fixed side plate and is used to assist in the fixing and positioning of the connecting pipe.

[0009] To prevent damage to the connecting tube during the fixing process, a silicone pad is provided on the outside of the trigger button.

[0010] To control the operation of the electromagnet, the trigger button is electrically connected to the electromagnet. The two sets of trigger buttons are connected in series. Only when the two sets of trigger buttons contact the inner wall of the rotating cylinder and the connecting pipe respectively, the internal circuit is controlled to conduct, thereby transforming the magnetorheological fluid into a solid-like property. This makes it difficult for the two sets of piston moving rods to drive the piston moving plate to move, achieving the effect that the trigger button stops moving after fixing the connecting pipe, thus achieving all-round fixation.

[0011] Furthermore, the contact layer is arc-shaped to easily adapt to the appearance of the connecting pipe.

[0012] Furthermore, the rotating cylinder is a hollow cylindrical body, and while controlling the rotation of the rotating arc plate, the movement trajectory of each part does not interfere with the contact partition and the fixed rotating shaft.

[0013] Furthermore, the rotating arc plate and the protruding connecting plate are made of rubber material.

[0014] Furthermore, the guide gear ring and the rotating gear are meshed together.

[0015] The fixed rotating shaft and the contact partition pass through the rotating cylinder from the inside.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: This solution provides a general surgical enterostomy fixation device, which effectively solves the problem that existing general surgical enterostomy fixation devices cannot simultaneously achieve all-round fixation and keep the connecting tube undamaged. This method brings the following advantages: To control the operation of the electromagnet, the trigger button is electrically connected to the electromagnet. The two sets of trigger buttons are connected in series. Only when the two sets of trigger buttons contact the inner wall of the rotating cylinder and the connecting tube respectively, the internal circuit is activated, thereby turning the magnetorheological fluid into a solid-like property. This makes it difficult for the two sets of piston moving rods to move the piston moving plate, achieving the effect of fixing the connecting tube after the trigger button is fixed. The several sets of automatic fixing devices can not only contact the uneven parts on the connecting tube to achieve all-round fixation of the connecting tube, but also the piston moving rod can provide the patient with protection for the connecting tube during movement through the magnetorheological fluid, preventing damage to the connecting tube while fixing it. The connecting pipe is fixed and connected from both sides by two sets of constraint clamping components. The connecting pipe is initially fixed by rotating the arc plate and the protruding connecting plate, and then the connecting pipe is completely fixed by the automatic fixing device, resulting in a better fixing effect.

[0022] like Figures 1-2 As shown, the present invention provides a general surgical enterostomy fixation device, including an automatic fixation device 1, a constraint clamping assembly 2, a drive motor 3, and a fixing base 4. The drive motor 3 is mounted on the fixing base 4 via a base. The constraint clamping assembly 2 is arranged in two groups on the fixing base 4, and the constraint clamping assembly 2 is connected to the drive motor 3 by transmission. The constraint clamping assembly 2 is provided with a contact partition 5, and the automatic fixation device 1 is arranged in a surrounding array on the contact partition 5. The two groups of constraint clamping assemblies 2 achieve the effect of fixing the connecting tube from both sides for initial fixation, and then the automatic fixation device 1 completely fixes the connecting tube, resulting in a better fixation effect.

[0023] like Figures 1-4 As shown, the automatic fixing device 1 includes a symmetrical cylinder 6, a piston moving rod 7, a piston moving plate 8, a magnetorheological fluid 9, an electromagnet 10, a trigger button 11, and a docking cylinder 12. The docking cylinder 12 is embedded in the contact partition 5. The electromagnet 10 is located at the bottom of the docking cylinder 12. The symmetrical cylinder 6 is divided into two groups and connected on both sides of the docking cylinder 12. The piston moving plate 8 is piston-slidably disposed inside the symmetrical cylinder 6. The piston moving rod 7 is disposed on the piston moving plate 8. The trigger button 11 is disposed on the piston moving rod 7 at the end away from the piston moving plate 8. A fluid moving cavity is formed between the two groups of piston moving plates 8, and the magnetorheological fluid 9 flows in the fluid moving cavity.

[0024] like Figures 1-2 and Figures 5-7As shown, the constraint clamping assembly 2 includes a rotating base 13, a guide gear ring 14, a rotating gear 15, a rotating cylinder 16, a fixed side plate 17, a rotating arc plate 18, a protruding connecting plate 19, a transmission arc groove 20, a rotating connecting column 21, and a fixed rotating shaft 22. The rotating gear 15 is connected to the output end of the drive motor 3. The rotating base 13 is fixedly connected to the fixed base 4. The guide gear ring 14 is fitted and rotatably disposed on the rotating base 13. The rotating cylinder 16 is fixedly connected to the inner wall of the guide gear ring 14. The fixed side plate 17 is fixedly connected to the fixed shaft 22. The fixed base 4 is attached to the fixed rotating shaft 22, which is located on the fixed side plate 17. The rotating connecting column 21 is located on the rotating cylinder 16 at the end away from the fixed side plate 17. The rotating arc plate 18 is rotatably located on the fixed rotating shaft 22. The protruding connecting plate 19 is located on the rotating arc plate 18. The transmission arc groove 20 is located on the protruding connecting plate 19. The rotating connecting column 21 is fitted and slidably located in the transmission arc groove 20. The protruding connecting plate 19 is provided with a notch 23 for passing through the fixed rotating shaft 22 without interfering with the rotation of the protruding connecting plate 19.

[0025] like Figure 5 As shown, the contact partition 5 is fixed to the fixed side plate 17 and is used to assist in the fixing and connection of the connecting pipe.

[0026] like Figures 2-4 As shown, to avoid damage during the fixing of the connecting tube, a silicone pad is provided on the outside of the trigger button 11; in order to control the operation of the electromagnet 10, the trigger button 11 is electrically connected to the electromagnet 10, and the two sets of trigger buttons 11 are set in series. Only when the two sets of trigger buttons 11 contact the inner wall of the rotating cylinder 16 and the connecting tube respectively, the internal circuit is controlled to conduct, thereby transforming the magnetorheological fluid 9 into a solid-like property, making it difficult for the two sets of piston moving rods 7 to drive the piston moving plate 8 to move, thus achieving the effect that the trigger button 11 no longer moves after fixing the connecting tube, thereby achieving all-round fixing.

[0027] like Figure 5 As shown, the contact layer 5 is arc-shaped, which makes it easy to adapt to the appearance shape of the connecting pipe.

[0028] like Figure 2 , Figure 5 and Figure 6 As shown, the rotating cylinder 16 is a hollow cylindrical body. While controlling the rotation of the rotating arc plate 18, the movement trajectories of each part do not interfere with the contact partition 5 and the fixed rotating shaft 22; regarding the materials of the parts, Figure 5 The rotating arc plate 18 and the protruding connecting plate 19 are made of rubber material; the fixed rotating shaft 22 and the contact partition 5 pass through the rotating cylinder 16 from the inside.

[0029] like Figure 1 As shown, the guide gear ring 14 and the rotating gear 15 are meshed together.

[0030] In practical use, the connecting pipe is placed between the two sets of rotating cylinders 16, and the drive motor 3 is started. The rotating gear 15 then drives the rotating cylinder 16 to rotate via the guide gear ring 14. The rotating base 13 acts as a guide, causing the rotating connecting column 21 to rotate with the rotating cylinder 16. Through the transmission arc groove 20, it drives the rotating arc plate 18 to rotate around the fixed rotating shaft 22 as the center. This initially fixes the connecting pipe through the rotating arc plate 18 and the protruding connecting plate 19. After both ends of the connecting pipe contact several sets of automatic fixing devices 1 inside the rotating cylinder 16, the trigger button 11 on one set of piston moving rods 7 contacts the connecting pipe, while the trigger button 11 on the other set of piston moving rods 7 remains in contact with the inside of the rotating cylinder 16. The two sets of trigger buttons 11 are connected in series. Only when the two sets of trigger buttons 11 contact the inner wall of the rotating cylinder 16 and the connecting tube respectively, will the internal circuit be controlled to conduct, thereby transforming the magnetorheological fluid 9 into a solid-like property. This makes it difficult for the two sets of piston moving rods 7 to drive the piston moving plate 8 to move, achieving the effect that the piston moving rod 7 will no longer move after the trigger button 11 fixes the connecting tube. The several sets of automatic fixing devices 1 can not only contact the uneven parts on the connecting tube to achieve all-round fixation of the connecting tube, but also the piston moving rod 7 can provide the patient with a shock-absorbing effect on the connecting tube during movement through the magnetorheological fluid 9, and prevent the connecting tube from being damaged while connecting the connecting tube and the ostomy bag.
