Embodiment Construction

[0041] Embodiments of the present invention are disclosed herein, however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be practiced in various ways. Therefore, this disclosure is not to be interpreted as limiting, but merely as a basis for the claims and as a basis for teaching one skilled in the art how to use the invention.

[0042] refer to figure 1 , for the convenience of expression, the side close to the operator is defined as the proximal end, and the side far away from the operator is defined as the far end.

[0043] When performing laparoscopic surgery, a puncture sleeve assembly (not shown) is usually used to establish a surgical channel for instruments to enter and exit the patient's body on the patient's body wall. Various minimally invasive surgical instruments, such as hand-held instruments 10, can be formed by the sleeve assembly. The channel is inserted into the body cavity. It may be necessary to use...

Abstract

The present invention relates to an improved laparoscopic scissors comprising a first blade and a second blade, wherein the first blade comprises a first proximal driving portion and a first distal blade body and a first mounting portion connected thereto; The second blade comprises a second proximal drive portion and a second distal blade body and a second mounting portion connected thereto, the first blade body comprising a first tip, a first mating surface, a first edge surface and a second blade body An outer surface, the first blade body also includes a first grinding surface, the first grinding surface intersects with the first mating surface to form a first grinding edge; the first grinding surface and the first The intersection of cutting edge surfaces forms a first transitional edge, and the intersection of the first cutting edge surface and the first outer surface forms a second transitional edge; the first sharpening surface and the first mating surface define a first edge angle ANG1, so The first edge surface and the first mating surface define a second edge angle ANG2, and ANG1>ANG2.

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to an improved laparoscopic scissors. Background technique [0002] Surgical instruments have a history of hundreds of years. During surgery, doctors use different surgical instruments to complete operations such as tissue grasping, cutting, separation, coagulation, and suture closure. Surgical instruments have matured after hundreds of years of development. Laparoscopic surgery has been clinically carried out for more than 30 years and is making rapid progress. To put it simply, laparoscopic surgery (including laparoscopic surgery and fiberoptic endoscopic surgery) means that the surgeon uses an elongated laparoscopic hand-held instrument to enter the patient's body through the natural orifice or a constructed puncture channel to complete tissue grasping, cutting , Separation, coagulation, suture closure and other operations. [0003] Compared with traditional open surg...
