Abstract

The present invention discloses a metamorphic tool hand for abdominal cavity minimal invasive surgery robot, which comprises the following components: a finger mechanism which is composed of a forefinger, a middle finger and a thumb; a palm mechanism; a metamorphic executing mechanism; a basal rod mechanism; a driving detecting mechanism and a special tool. The forefinger and the middle finger arehinged in the palm mechanism. The metamorphic executing mechanism is hinged between the palm mechanism and the basal rod mechanism. The palm mechanism and the thumb are respectively hinged with the basal rod mechanism. The basal rod mechanism is connected with the driving detecting mechanism through the soft wire provided in the metal flexible pipe. The basal rod mechanism is equipped in the robot body through screw bolts and move along with the robot body. The joint of the tool hand is driven by the soft wire in the metal flexible pipe. The middle finger and the thumb can be retreated into the basal rod. The forefinger is straight and is parallel with the basal rod. The whole body of the metamorphic tool hand can enter and come out from the scarfskin of the abdominal cavity. The metamorphic tool hand expands to the tool hand with different configuration after entering the abdominal cavity. The metamorphic tool hand not only can directly operate the organ and tissue of the abdominal cavity but also can grasp the tool for indirectly operation.

Description

technical field [0001] The present invention relates to a minimally invasive surgical robotic medical device, in particular to a minimally invasive abdominal cavity that can enter the interior of the abdominal cavity, can be extended and contracted as a whole, its topological structure can be changed, has multiple operating functions, and is easy to use and flexible to operate. Surgical robot with metamorphic tool hand. Background technique [0002] Minimally invasive surgery is to use advanced surgical instruments and equipment to complete the operation with less trauma, and achieve better curative effect than traditional open surgery. After robot technology entered the field of minimally invasive surgery, in order to complete complex surgical operations, the end tool of the robot requires high flexibility. The end tool has developed from the initial single-degree-of-freedom configuration to a multi-degree-of-freedom configuration. Tools lack the ability to operate on larg...
