The working principle of the double-needle concurrent fascia suture device is explained as follows:
firstly, before an operation, a suture line can be orderly embedded into the line grooves 1-6, and the first restraint groove 1-4 and the second restraint groove 1-5 are restrained by the first restraint piece 6 (which can be made of soft silica gel) and the second restraint piece 7 (which can be made of soft silica gel) so as to be in a tightened state, and at the moment, the suture line is in a tightened state at the groove openings 1-11.
Secondly, the wound fascia closer is inserted into a minimally invasive incision of the abdominal cavity of a patient to a proper depth, the handle part 2 is rotated to enable the limiting protrusion 2-1 to be separated from the first external locking position 1-1, and meanwhile, the extension protrusion 8-1 is driven to be separated from the first internal locking position 1-8, so that the unlocking operation during chuck closing and locking is completed; downward pressure is applied to the handle part, the first return spring 9 arranged in the handle part generates compression deformation, the limiting rod 8, the extension rod 11 and the push-pull rod 12 are sequentially driven to move downwards, meanwhile, the two chucks 4 are driven to rotate 90 degrees around the restraining protrusions 1-12, the chucks are closed to open, the handle part 2 rotates in the opposite direction after the handle part 2 is pressed to the tail end of the stroke, namely the chucks are opened, so that the limiting protrusions enter the second outer locking positions 1-2, meanwhile, the outer protrusions 8-1 enter the second inner locking positions 1-9, and locking operation after the chucks are opened is completed.
Thirdly, the fascia suture device with the opened chuck 4 and in a locking state is lifted to enable the fascia suture device to be tightly attached to the inner wall of an abdominal cavity, downward pressure is applied to the trigger 3, the second return spring 10 generates compression deformation, the trigger 3 drives the two needle bodies 13 (namely the double needles 13) fixedly connected with the trigger 3 to rapidly move downwards along the sliding grooves 1-10, one end of the tightened suture line respectively enters the groove and is driven by the suture line to puncture a fascia layer when the thread hanging groove 13-1 of each needle body passes through the notch 1-11, the thread hanging groove sequentially passes through the needle inlet hole 4-3 and the silica gel plug arranged in the window 4-2, and finally the thread hanging groove is driven by the suture line to come out of the needle outlet hole 4-1, so that the operations of thread hanging and needle inlet puncture are completed.
Fourthly, the trigger 3 is pulled back, and the trigger 3 and the double needles 13 are reset under the action of the elastic restoring force of the second return spring 10, namely the needle body enters the sliding grooves 1-10. At this time, both ends of the suture thread are respectively retained inside the cartridge by the resistance action of the silicone plug. The handle part 2 is rotated reversely to cause the limiting protrusion 2-1 to be separated from the second outer locking position 1-2, the outer extending protrusion 8-1 is separated from the second inner locking position 1-9, the limiting rod 8, the extending rod 11 and the push-pull rod 12 are driven to move upwards under the action of the deformation recovery of the built-in first reset spring 9, the two chucks are driven to be closed, then the handle part is rotated reversely to enable the limiting protrusion 2-1 to enter the first outer locking position 1-1 again, the outer extending protrusion 8-1 enters the first inner locking position 1-8 again, and the belt line closing and locking of the chucks are completed. And finally, pulling out the suturing device in a closed and locked state from the minimally invasive incision, and knotting the suture line outside the body.
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.
