Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1 to 4, a suture retractor for laparoscopic surgery includes an outer sheath 1 and a retractor, the retractor is partially slidably disposed in the outer sheath 1, the retractor includes a push-pull part 2, a rod part 3 and an elastic part 4 coaxially and fixedly connected in sequence, the push-pull part 2 is pushed to make the elastic part 4 slidably extend out of the outer sheath 1 and then be in an expanded state, the elastic part 4 is expanded to form a through hole 4a for penetrating a suture, and the push-pull part 2 is pulled to make the elastic part 4 extend into the outer sheath 1 and be in a compressed state.

In this embodiment, the outer sheath 1 has an outer diameter of 5mm to 10mm, and is made of a medical metal material such as a stainless steel pipe.

In this embodiment, the elastic portion 4 is a ring-shaped metal spring piece, preferably an oval spring piece, so as to form a through hole 4a with a larger aperture, and further preferably, the aperture of the through hole 4a formed after the elastic portion 4 is unfolded is between 2mm and 4 mm.

In this embodiment, the end of the elastic portion 4 away from the rod body portion 3 is fixedly provided with the puncturing portion 5, the end face of the head of the outer sheath tube 1 is a beveled face, the end face of the head of the puncturing portion 5 is a beveled face parallel to the end face of the outer sheath tube 1, the outer wall of the head of the rod body portion 3 is axially provided with at least one sliding strip 3a, the inner wall of the tail of the outer sheath tube 1 is axially provided with a sliding groove in sliding fit with the sliding strip 3a, and the rod body portion 3 and the outer sheath tube 1 are connected in a manner that the sliding strip 3a is matched with the sliding groove, so that the rod body portion 3 can directionally slide along the axial. The inner wall of the tail end of the outer sheath tube 1 is provided with a limiting ring 1a, when the slide bar 3a is abutted against the limiting ring 1a, the head end surface of the puncture part 5 is coplanar with the head end surface of the outer sheath tube 1, and at the moment, the outer sheath tube 1 and the puncture part 5 can be punctured together.

In the present embodiment, the push-pull portion 2, the shaft portion 3, and the puncture portion 5 are made of a medical metal material.

When the laparoscopic surgery suture retractor provided by the utility model is used, in the first step, the head of the suture retractor is punctured into a laparoscopic operation space from an operation area incision; secondly, holding the external sheath tube 1 by one hand, pushing the push-pull part 2 by the other hand to enable the elastic part 4 to extend out of the external sheath tube 1, and enabling the elastic part 4 to lose the abutting pressure of the external sheath tube 1 to be in an unfolded state; thirdly, the suture thread is penetrated through the through hole 4a, and the push-pull part 2 is pulled to enable the elastic part 4 to be retracted into the sheath tube 1; and fourthly, pulling out the head of the suture line retractor from the body, and fixing the suture line in the body to finish the traction.
