Abstract

The invention relates to a multi-freedom micro mechanical hand used in micro-hurt surgery. The invention comprises a base, an upper drawing device with terminal tool transmitter, a lower drawing device, a self-rotation device and an executor of terminal tool, and a transmitter box. The servo motor of base via the coupler is connected with the lower clutch disc fixed on the motor frame via rolling bearing; the transmitter box is arranged on the upper face of motor frame; the upper and lower drawing devices and the self-rotation device are in the transmitter box, while the upper ends are fixed on the top face of transmitter box and lower ends are through the bottom of box to connect the lower clutch disc, and the front ends via their own upper drawing sheath, lower drawing sheath and self-rotation muffle are connected from up to down; the lower end of self-rotation muffle is connected with the executor of terminal tool. The invention has bend freedom, therefore, the terminal tool can be switched freely, with simple structure, high bearing ability and reliable transmission of terminal tool.

Description

technical field [0001] The invention relates to a medical device for surgery. In particular, it relates to a convenient and flexible multi-degree-of-freedom micromanipulator for minimally invasive surgery. Background technique [0002] Minimally invasive surgery is the use of advanced surgical instruments and equipment to complete the operation with minimal trauma and achieve the same curative effect as traditional open surgery. Among them, surgical tools for minimally invasive laryngeal surgery generally need to be operated under a laryngoscope through the oral cavity and laryngeal cavity, and the surgical space is relatively narrow. Therefore, this type of surgery is a difficulty in minimally invasive surgery. At present, this type of operation cannot handle complex laryngeal operations such as vocal cord suture and subvocal cyst removal, and laryngectomy has to be used for such operations. Therefore, there is an urgent need for a micro-manipulator so as to extend the do...
