Abstract

The present application relates to a minimally invasive surgical instrument. The minimally invasive surgical instrument includes a hand-held body, which is characterized in that the minimally invasive surgical instrument also includes: a holder for clamping the lesion tissue; a curved rod with a flexible structure, and its end is fixed to the hand-held body the other end of which is connected to the end of the holder; and a rope set, which connects the holder and the hand-held body via the bending rod. Wherein, the rope set includes a first rope set and a second rope set, and the handheld body includes: a bending controller capable of controllably bending to pull the first rope set, so that the bending rod a flexible structure bends; and a grip controller controllably pivotable to pull the second set of cords to cause the gripper to grip or loosen.

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to a hand-held flexible minimally invasive surgical instrument. Background technique [0002] During minimally invasive surgery, the doctor makes one or several small holes in the patient's epidermis, then inserts minimally invasive surgical instruments into the patient's lesion through the small holes, and completes the operation through external control instruments. Compared with traditional surgery, minimally invasive surgery has the advantages of less trauma, faster recovery of body functions, shorter hospital stay, and less postoperative scars. Therefore, minimally invasive surgery is an important development direction of medical surgery. However, due to the narrow operating space of minimally invasive surgery and the low degree of freedom of minimally invasive surgical instruments, minimally invasive surgery has high requirements for doctors' surgical skills, and at ...
