Improved structure of laparoscopic surgery instrument handle

Abstract

The invention discloses an improved structure of a laparoscopic surgery instrument handle and aims at leading hand feeling to be close to the natural state when a thumb and an index finger touch each other with strength by aid of the lever energy saving principle, reducing hand fatigue and shorting operation time. The improved structure comprises the instrument handle, wherein the instrument handle is composed of a fixed handle fixed on a handle seat and a moving handle hinged to the handle seat, a sliding rod is arranged between the lower end of the fixed handle and the moving handle, and the front end of the sliding rod is hinged to the fixed handle. A sliding chute penetrating the front end surface and the back end surface of the moving handle is arranged on the moving handle, the back end of the sliding rod extends into the moving handle from the front end surface of the moving handle, passes through the sliding chute and extends out from the back end surface of the moving handle, and a finger sleeve ring is arranged at the back end of the sliding rod. Compared with the prior art, the sliding rod extending in the direction of the moving handle is hinged at the lower end of the fixed handle, the back end of the sliding rod extends into the moving handle from the front end of the moving handle, passes through the sliding chute and extends out from the back end of the moving handle, the sliding rod can slide in the sliding chute when external force is applied to the moving handle, and therefore the force application intensity and operation fatigue of operators are reduced.

Description

technical field [0001] The invention relates to a medical instrument, in particular to an improved structure of a laparoscopic surgical instrument handle. Background technique [0002] In the past 20 years, with the advancement of science and technology, laparoscopic surgery has been widely recognized by doctors and patients. The safety, effectiveness and minimal invasiveness of laparoscopic surgery have gradually been recognized, and the scope of application has become wider and wider. At present, although the handles of the most commonly used surgical instruments for laparoscopy, such as various forceps and scissors, are convenient to operate, they cannot save labor to the maximum extent when using them, and when applying force, the surgical instruments do not feel good, which makes the operator feel uncomfortable during the operation. In the middle, it is easy to fatigue the hand or fail to grasp the forceps, which will affect the operation time. Contents of the inventi...

At present, although the handles of the most commonly used surgical instruments for laparoscopy, such as various forceps and scissors, are convenient to operate, they cannot save labor to the maximum extent when using them, and when applying force, the surgical instruments do not feel good, which makes the operator feel uncomfortable during the operation. In the middle, it is easy to fatigue the hand or the forceps cannot grasp it, which will affect the operation time
