Description

Minimally invasive fascia closer with locking device

Technical Field

The utility model belongs to the technical field of fascia closers, and particularly relates to a minimally invasive fascia closer with a locking device.

Background

In recent years, minimally invasive surgery, which has the advantages of small wound, quick recovery, high cure rate and the like, has been developed rapidly, and laparoscopic surgery, which is representative of minimally invasive surgery, is widely used in the field of surgical operations, involving many kinds of diseases and operations. To accommodate the closing of the incision in the abdominal wall puncture site in the field, the surgical incision has recently begun to be sutured using fascia closure devices. The operation method has the advantages of simple operation, good suture effect and the like, and is widely used in clinic.

When the fascia closer is used, the thread leading needle with the suture thread penetrates through the silica gel gasket on the wing plate, the suture thread is extruded by the silica gel gasket when the thread leading needle is pulled out, one end of the suture thread is limited on one wing plate, the suture thread cannot exit along with the thread leading needle, and the suture thread knotting can be carried out on the sutured fascia under the direct vision after the other end of the suture thread is led out of the body. At the moment, the wing plate is in a locking state during the puncture and suture process of the threading needle, so that the wing plate is ensured not to shake, and the suture line is ensured to be clamped and sutured accurately. However, in the actual clinical practice, the existing fascia closer is not provided with a device and a mark for locking the wing plate, so that the operation cannot be completed in time during the operation process, and the suture failure is often caused.

Chinese utility model patent publication No. CN210843244U discloses a minimally invasive fascia closer with a locking device, which comprises a closing fastener and a suture passer; the suture threading device comprises a thread guiding needle and a long handle; the closing firmware comprises an annular handle, a body, a transmission rod and wing plates; the side wall of the annular handle is provided with a mark, the lower end of the annular handle is inserted into the device body and is connected with the transmission rod, and the lower end of the transmission rod is hinged with two wing plates which are symmetrically arranged; the side wall of the part of the lower end of the annular handle inserted into the body is provided with a positioning bulge; the inner wall of the device body is provided with a limiting block and a locking groove; and a positioning hole matched with the positioning bulge is arranged in the locking groove. The utility model has the beneficial effects that: the annular handle can be effectively fixed through the matching of the positioning protrusion, the locking groove and the positioning hole, so that a good locking and fixing effect is achieved on the wing plate, and the wing plate is prevented from shaking; and because the side wall of the annular handle is also provided with the mark, whether the wing plate is in the locking state or not can be intuitively known through the mark, and the operation is more convenient.
