Description

Technical Field

[0001] The invention relates to the field of medical instruments, in particular to an abdominal puncture and suturing device. Background Art

[0002] With the development of medical device technology, minimally invasive surgery with the advantages of less trauma, faster recovery, and higher cure rate has also developed rapidly. As a representative of minimally invasive surgery, laparoscopic surgery involves multiple departments and multiple diseases and is widely used in the field of surgery. The abdominal puncture device is a commonly used surgical instrument in abdominal surgery, mainly used to establish artificial pneumoperitoneum and instrument channels in laparoscopic surgery. The inner wall of the postoperative puncture hole is too deep to perform surgical sutures. Usually, a hemostatic cotton ball is inserted and a postoperative patch is applied to the outside to allow the wound to heal. Sometimes it can cause wound infection and cannot heal for a long time, resulting in abdominal infection and the formation of puncture hole hernia, which brings pain to the patient.

[0003] Although there are staplers available, it is necessary to first remove the puncture device from the wound and then insert the stapler for suturing. The process of switching instruments is cumbersome and can easily lead to uneven suturing on both sides of the wound, failure to align the fascia tissue, and risks of wound infection, which prolongs the healing time of the fascia.

The suturing device 3 has an upper through hole 32 and a lower through hole 33 corresponding to the upper puncture groove 122 and the lower puncture groove 123, and the puncture tube 51 and the suture thread 6 pass through the puncture sleeve 12 and the suturing device 3 in an oblique manner through the guide hole 112, the upper puncture groove 122, the upper through hole 32, the lower through hole 33 and the lower puncture groove 123 in sequence. The number of the upper puncture groove 122, the lower puncture groove 123, the upper through hole 32, and the lower through hole 33 is 2.

[0032] In addition, the lower end of the puncture sleeve 12 has an anti-slip groove section 124, and the upper puncture groove 122 and the lower puncture groove 123 are arranged on the anti-slip groove section 124. A silicone sleeve 125 is arranged in the anti-slip groove section, and the transparent silicone sleeve 125 is directly sleeved or wrapped on the puncture sleeve 12, and the material is silicone or TPE or other soft materials.

[0033] In addition, the lower end of the sealing cover 2 is provided with a first buckle 21, the lower end of the suture device 3 is provided with a second buckle 31, and the upper end of the connecting seat 11 is provided with a first card slot 113 in which the first buckle 21 and the second buckle 31 cooperate.

The structures of the rest of the suture device 3, the puncture cone 4 and the hook 5 mentioned in this application are all existing conventional structures.

[0034] In addition, the guide bracket 111 is fixedly connected to the connecting seat 11 .

[0035] In another embodiment, the guide bracket 111 is rotatably connected to the connecting base 12 via a rotating shaft, and may also be rotatably connected to the connecting base 12 via other structures such as hinges.

[0036] See also Figures 6 to 11The specific working principle of the abdominal puncture and suturing device of the present invention is as follows: the sealing cover 2 is installed on the connecting seat 11, and then the puncture cone 4 is installed on the sealing cover 2, and enters the abdominal cavity through abdominal wall puncture, and then the puncture cone 4 is pulled out; the surgical instrument is passed through the puncture device 1 to enter the abdominal cavity for surgical operation, and the surgical instrument is pulled out after the operation is completed, and the sealing cover 2 is removed; the suture device 3 with suture wound is inserted into the puncture sleeve 12, and connected with the connecting seat 11 through the buckle; press the lock button and pull it upward until the lock button enters the upper end positioning groove, the movable bracket is fully opened, and the puncture sleeve 12 is pulled upward until the movable bracket contacts the inner fascia layer of the abdominal wall; the hooking device 5 is inserted along the guide hole 112 on one side of the upper end of the puncture sleeve 12, and the puncture tube 51 enters the suture device 3 through the upper puncture groove 122 and then through the lower puncture groove 123, passes through the lower layer of the abdominal wall tissue, and then enters the hooking hole of the movable bracket, at this time The handle of the hooking device 5 is pushed against the puncture sleeve 12 The outer shell of the thread hook 5 is matched with the arc surface 115 on the outer shell of the puncture sleeve 12, and the thread hook 5 cannot be rotated at will; the thread hook 5 is used according to the surgical regulations until the thread hook needle completely hooks the suture and is inserted into the puncture sleeve 12, the thread hook 5 enters a tightening state, and the thread hook 5 is pulled out along the guide hole. At the same time, one end of the suture is brought out along the lower layer of the abdominal wall tissue and the guide hole in turn and left outside the puncture sleeve 12; press the button on the movable lock of the thread hook 5 The elastic buckle releases the thread hook; the thread hook 5 is inserted from the guide hole 112 on the other side, and the above steps are repeated. Finally, the puncture device 1 is pulled out from the abdominal wall puncture hole together with the suture device 3, and the suture is pulled out of the instrument, and the two ends of the suture are left outside the abdominal wall puncture hole, while the middle part of the suture is left in the abdominal wall puncture hole and passes through the lower abdominal wall tissues on both sides. According to the conventional method, the fascia suturing work is performed, that is, the suture is tied and the excess part of the suture is removed.

[0037] Different from the prior art, the abdominal puncture suturing device of the present invention can solve the problem of frequent replacement of instruments during surgery, ensure uniform wound suturing, keep fascia tissue aligned, reduce the risk of wound infection, and has a simple structure, is easy to use, and is safe and reliable.
