Description

Technical Field

[0001] The utility model relates to the technical field of puncture hole sealers, in particular to an inward-adducting abdominal wall puncture hole sealer and a conveyor thereof. Background Art

[0002] The puncture hole is a puncture hole made by the laparoscopic puncture device on the abdominal wall, which is a type of abdominal surgical incision. If the puncture hole is not closed properly, a puncture hernia will occur. A puncture hernia is mainly caused by the puncture hole in the abdominal wall not being closed tightly, puncture infection, and puncture fissure.

[0003] Except for the rectus abdominis, the fibers of the various layers of muscle, fascia, and sheath of the abdominal wall generally run horizontally. Longitudinal incisions are bound to cut these fibers. When suturing these tissues, the sutures are prone to slipping between the fibers; the sutured tissues are often subject to the lateral traction of the muscles and are prone to puncture and tearing. In addition, since the puncture holes are small, usually only 5 to 15 mm in diameter, the suturing operation is very difficult. If the wound edges are forcibly pulled together during suturing, causing tissue tearing, it will also lead to the occurrence of puncture hernia. According to data, if the incision is healed by the first intention after abdominal surgery, the incidence of incisional hernia is usually less than 1%, but if the incision is infected, the incidence can reach 10%; if the wound is open, it can even be as high as 30%. Some literature points out that puncture hernia is not only prone to complications such as intestinal obstruction and incarceration necrosis, forcing patients to undergo emergency surgical intervention, but also increases the mortality rate of patients.

[0022] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0023] like Figure 2 and Figure 4As shown, an inward-adducting abdominal wall puncture sealer mainly includes a closing disk 10 and a lifting rod 20. The closing disk 10 is a circular hard sheet with a thickness of 0.5-5 mm. The upper and lower end surfaces of the closing disk 10 are respectively the peritoneal surface facing the peritoneum and the abdominal cavity surface facing the abdominal cavity. At least two barbed nails 15 inclined and lying toward the inner circle are arranged on the peritoneal surface of the closing disk 10, and at least two barbed nails 15 are evenly distributed along the circumferential direction. The lower end of the lifting rod 20 is clamped at the center position of the closing disk 10. The lifting rod 20 can drive the closing disk 10 to close to the abdominal wall, drive the barbed nails 15 to penetrate the abdominal wall and fix it, and close the abdominal wall puncture. The surface of the lifting rod 20 is provided with scales along the length direction, and the scales can intuitively indicate the depth of the lifting rod 20 entering the abdominal cavity. The cross section of the lifting rod 20 is a flat structure, and the long axis of the cross section of the lifting rod 20 is parallel to the surgical incision line.

[0024] like Figure 4 As shown, a mounting hole 12 is provided at the center of the closing disk 10 and extends vertically therethrough. Figure 2 As shown, two clamping blocks 21 are arranged on the side of the lower end of the lifting rod 20, and the two clamping blocks 21 are arranged symmetrically with the lifting rod 20 as the center, and the lower end faces of the two clamping blocks 21 are flush with the lower end face of the lifting rod 20. The shape formed by the connection between the lower end faces of the two clamping blocks 21 and the lower end face of the lifting rod 20 is consistent with the cross-sectional shape of the mounting hole 12, and the lower end of the lifting rod 20 and the two clamping blocks 21 can be installed in the mounting hole 12 from top to bottom. Two concave axial locking grooves 13 are arranged on the lower end face of the closing disk 10, and the two axial locking grooves 13 are respectively located on the sides of the left and right ends of the mounting hole 12. After the lower end of the lifting rod 20 and the two clamping blocks 21 enter the mounting hole 12, the lifting rod 20 is rotated, and the two clamping blocks 21 can be respectively screwed into the two axial locking grooves 13, and the upper end faces of the two clamping blocks 21 and the lower end faces of the two axial locking grooves 13 are respectively in contact, so as to realize the axial locking of the position of the lifting rod 20. A recessed circumferential locking groove 14 is respectively arranged on the bottom end faces of the two axial locking grooves 13, and an upwardly protruding locking block 22 is respectively arranged on the upper end faces of the two clamping blocks 21.

The ratchet 31 is located in the inner circle of the circumference of the barbed nail 15, and the ratchet 31 can rotate under the drive of the sleeve 30. When the ratchet 31 rotates, the ratchet teeth contact the barbed nail 15 and can open the barbed nail 15 to the outer circle, so that the barbed nail 15 is in a vertical state. When the ratchet teeth of the ratchet 31 leave the barbed nail 15, the support for the barbed nail 15 is lost, and the barbed nail 15 is in a state of falling toward the inner circle. In the process of the barbed nail 12 restoring the inclined falling state, the puncture hole that has been closed into a linear mouth is tightened and fixed tightly, and a compression hemostasis effect is generated, so that the puncture hole is in a tension-free state outward. After the puncture hole is closed, the lifting rod 20 can be pulled out of the body together with the sleeve 30, and the lifting rod 20 in the sleeve 30 is the central axis of the sleeve 30 rotation.

[0027] like Figure 1 and Figure 2 As shown, the upper end of the lifting rod 20 is fixedly connected to a limit block 32, and the limit block 32 is used for limiting the position when installed in the conveyor.

A plurality of drug unloading holes 18 are provided on the buckle plate 16, and the plurality of drug unloading holes 18 are connected to the plurality of drug loading holes 11 in a one-to-one correspondence.

[0029] like Figure 6 As shown, a conveyor of an inward-retracting abdominal wall puncture sealer mainly includes an intermediate conveying tube 40, the upper and lower ends of which are respectively connected to an upper conveying sleeve 42 and a lower conveying sleeve 41, the intermediate conveying tube 40, the upper conveying sleeve 42 and the lower conveying sleeve 41 are integrally formed, and the inner cavity diameters of the upper conveying sleeve 42 and the lower conveying sleeve 41 are larger than the inner cavity diameter of the intermediate conveying tube 40. A sleeve 30 is arranged in the intermediate conveying tube 40, a lifting rod 20 is arranged in the sleeve 30, the lower end of the lifting rod 20 is clamped with a closing disk 10, and the closing disk 10 is arranged in the lower conveying sleeve 41. The upper end of the sleeve 30 is connected to a limit block 32, a card 43 is mounted on the sleeve 30, the lower end surface of the card 43 contacts the inner end surface of the upper conveying sleeve 42, and the upper end surface of the card 43 contacts the limit block 32. The inward-retracting abdominal wall puncture sealer is pre-installed in the conveyor before use, and enters the abdominal cavity through the puncture device when used.

[0030] The working principle of the utility model is as follows: when closing the abdomen after the laparoscopic surgery, a conveyor pre-installed with an inward-adducting abdominal wall puncture sealer and matched with the inner diameter of the puncture device is inserted into the puncture device to the limit position. The puncture device and the conveyor are pulled out of the puncture hole, and the sleeve 30 is rotated to the right position to support the barbed nail 12 to a vertical state. The lifting rod 20 is lifted up until resistance is felt (so that the closing disk 10 is close to the abdominal wall), and the length (scale) of the lifting rod 20 in the puncture hole is recorded. Check and adjust the long axis of the cross section of the lifting rod 20 to be parallel to the surgical incision line. Squeeze the incision epidermis to close the incision, and at the same time, forcefully lift the lifting rod 20 upward to make the barbed nail 12 penetrate the abdominal wall tissue, and the scale shows that the barbed nail 12 is fully penetrated by shortening one nail length. Push the lifting rod 20 downward without moving, and confirm that the fixing of the closing disk 10 is completed. Rotate the sleeve 30 to remove the external support effect of the ratchet, so that the barbed nail 12 returns to the centripetal leaning position, and the puncture closed into the incision line is tightly tightened. The lifting rod 20 is rotated to a position where it is disengaged from the closing disk 10 , and the lifting rod 20 and the sleeve 30 are pulled out together.
