Handheld one-armed multi-degree-of-freedom laparoscope

Abstract

The invention discloses a handheld one-armed multi-degree-of-freedom laparoscope. The laparoscope is characterized by comprising a pair of operating forceps, an operating mechanical arm and a handheldpart, wherein the operating mechanical arm comprises an executing arm and an operating arm. The handheld one-armed multi-degree-of-freedom laparoscope has the beneficial effects that each joint of the executing arm of the operating mechanical arm and each joint of the operating arm of the operating mechanical arm are in one-to-one correspondence, the operating arm and the executing arm are in running fit through a gear running mode. When the handheld one-armed multi-degree-of-freedom laparoscope is used, a user can manually operate the operating arm, the executing arm is synchronously drivenby the operating arm to act correspondingly, and manually direct copying operation can be realized; tension adjustment of a stay cord can be realized, so that stable and accurate control of the operating forceps can be favored; a worm gear has a self-locking function, and is reliable in tensioning; and the operating joints of the operating arm can be independently locked, and the degree-of-freedomof the executing arm or the executing arm locking posture can be reduced, so that subsequent operation of an operator can be facilitated, and the probability of misoperation of the operator can be greatly reduced.

Description

technical field [0001] The invention relates to the field of laparoscopy, in particular to a hand-held single-arm multi-degree-of-freedom laparoscope. Background technique [0002] Laparoscopic surgery has the advantages of small wounds and quick recovery, and has been widely used in abdominal surgery, thoracic surgery, gynecology and urology. Hand-held single-arm multi-degree-of-freedom laparoscope is an important tool for artificial laparoscopic surgery. The opening and closing of the existing multi-degree-of-freedom laparoscopic surgical forceps are all rope-driven, but the pull rope has no tension adjustment device. After long-term use, it will be impossible to accurately control the opening and closing of the surgical forceps, and the joints are rope-driven, rigid Difference. Contents of the invention [0003] In order to solve the problems raised in the above-mentioned background technology, the present invention discloses a hand-held single-arm multi-degree-of-fre...
