The following is a description of the working principle of the quadriceps fascialis closer:
in the clinical practice, the closure device and the suture passer are required to be used in cooperation. Firstly, the puncture outfit is pulled out from an abdominal cavity puncture part, the closer with a chuck in a closing and locking state is inserted into a puncture hole to a proper depth (the chuck completely goes deep into the abdomen), then the pull ring is rotated along one direction, the pull ring drives the locking rod to rotate, the restraint of the extension arm is released from the first locking position in the turntable, then downward thrust is applied to the pull ring, at the moment, the locking rod and the push-pull rod move downwards along with the downward movement of the pull ring, meanwhile, the boss leaves the caulking groove, the swing rod slightly opens around the restraint piece, the four chucks rotate by 90 degrees to be completely opened, at the moment, the pull ring is rotated along the opposite direction, the extension arm is driven to enter a second locking position, and therefore the operation that the closer enters an abdominal cavity opening, and; the closer with the four effectively opened clamping heads is lifted upwards until the clamping heads of the closer are tightly attached to the inner wall of the abdominal cavity; one end of a first suture is embedded into the line embedding groove, the guide hole pierces through the abdominal wall fascia layer after coming out from the line outlet hole along the guide groove, the needle inlet hole pierces into the silica gel plug arranged in the window, and then the silica gel plug penetrates out from the line outlet hole, so that the needle inserting operation of the needle body line embedding groove with a line penetrating through the silica gel plug is completed; then slightly pulling out the suture passer, and taking out from the wire embedding groove along with one end of the suture under the blocking of the silica gel plug to finish the wire feeding and withdrawing operations; the rotary disc is rotated for 180 degrees (if the rotary disc and the instrument body are in an integral structure, only the opposite guide hole is selected and needle insertion puncture is carried out), the guide hole is aligned with the opposite guide groove, at the moment, the other end of the suture is embedded into the embedding groove, needle feeding and needle pushing operations are carried out, and thus the thread feeding operation of the first suture is completed. The second suture thread feeding operation is then carried out: rotating the turntable for 90 degrees (if the turntable and the instrument body are in an integrated structure, only one of the other two non-thread-feeding guide holes needs to be selected), taking another suture thread, embedding one end of the suture thread into the thread embedding groove, and finishing thread feeding according to the needle inserting operation; and rotating the turntable for 180 degrees again (if the turntable and the instrument body are in an integrated structure, only the opposite non-thread feeding guide hole is selected), embedding the other end of the second suture thread into the thread embedding groove, and finishing thread feeding according to the needle inserting operation. So far, the wire feeding operation of two suture wires is completed simultaneously, namely the two ends of the first suture wire and the second suture wire pass through the abdominal wall fascia layer and the silica gel window and are left on the inner side of the chuck, the extension arm is driven to be separated from the second locking position by rotating the pull ring, the pull ring is lifted and reversely rotated, the extension arm smoothly enters the first locking position, meanwhile, the four chucks complete the closing and fixing actions, the closer is slightly pulled out of the body from the abdominal cavity, the two ends of the first suture wire and the second suture wire are both pulled out of the body and are pulled out of the silica gel plug, the corresponding two ends of each suture wire are knotted, and then the double-wire tight sewing of the fascia layer at the same minimally invasive incision is completed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
