Embodiment Construction

[0015] combine Figure 1~3 As shown, the present invention provides a laparoscopic retractor, comprising a puncture needle 1, a pull wire 2 and a pull button 3, the pull button 3 is in the shape of a cross, and a buttonhole 3a is provided in the middle; The other end is connected with the pulling button 3 through the buttonhole 3a. The needle body of the puncture needle 1 can be triangular, cylindrical or semi-cylindrical. The pulling button 3 is made of elastic materials such as silica gel.

[0016] combine Figure 4 As shown, as another modification, the pulling button 3 can also adopt a Y shape.

[0017] In laparoscopic surgery, grasp the pulling button 3 with grasping forceps, introduce the pulling button 3 into the abdominal puncture device until the puncture needle 1 passes through the abdominal puncture device, and then grasp the puncture needle 1 with the grasping forceps to puncture the abdominal wall. The abdominal wall tissue is pulled away, exposing the surgica...

Abstract

The invention discloses a laparoscopic retractor, which comprises a puncture needle, a pulling line and a pulling button; buttonholes are formed in the center of the pulling button; one end of the pulling line is riveted with the tail of the puncture needle, and the other end of the pulling line is connected with the pulling button through the buttonholes; The pulling button is cross-shaped or Y-shaped. In a laparoscopic operation, the pulling button is grasped by the grasping forceps, the pulling button is introduced into an abdominal puncture device until the puncture needle passes through the abdominal puncture device, and then the puncture needle is grasped by the grasping forceps. A punctured abdominal wall and tissue are pulled and opened, a surgical field of view and an operation space are exposed, and the operation is facilitated; the structure is simple, the damage is reduced, and the operation time is shortened; the pulling button is set to a cross or a Y shape, the size is reduced, points contacting the puncture tissue are increased, and a pulling effect is ensured while damage to the tissue is avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a laparoscopic retractor. Background technique [0002] Laparoscopic surgery is now a common surgical method, which has the advantages of less trauma and rapid healing after surgery. During the operation, in order to obtain a better surgical effect and ensure the exposure of the field of view in laparoscopic surgery, it is often necessary to insert a trocar through the abdominal wall and introduce operating forceps to assist in pulling the tissue, so as to facilitate the smooth operation. However, this method not only aggravates the injury of the patient and prolongs the operation time, but also increases the scar of the postoperative abdominal wall of the patient. Contents of the invention [0003] The object of the present invention is to provide a laparoscopic retractor, which can conveniently pull the punctured tissue in the laparoscopic operation, has a simple...
