Instrument box and operation instrument

Abstract

The invention provides an instrument box and an operation instrument. The instrument box comprises an overturning platform assembly, two sets of driving wires, two wire rotating bodies and four output wires; each set of the driving wires comprises two driving wires, two fixed points formed by each set of the driving wires on an internal rotating part are symmetrical about a first intersection point, the four fixed points formed by the four driving wires on the internal rotating part are sequentially connected to form a first parallelogram, the intersection point of diagonal lines of the first parallelogram is the first intersection point, the other ends of the two driving wires in each set of the driving wires are wound onto the corresponding wire rotating bodies in the opposite directions, and therefore the overturning platform assembly is driven to move on the basis of the four driving wires; then motion of the overturning platform assembly is transferred to a tail end instrument assembly through the output wires, multi-direction and multi-degree-of-freedom motion of the tail end instrument assembly is achieved, the design of the instrument box is simplified, the size of the instrument box is decreased, and the space use rate of the instrument box is increased.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an instrument box and a surgical instrument. Background technique [0002] Compared with conventional surgery, minimally invasive surgery has obvious advantages in terms of treatment effect, pain relief, recovery period, and medical cost. It mainly uses advanced medical instruments and equipment to perform surgery with minimal trauma. [0003] Traditional abdominal surgery mainly uses manual micro-instruments to operate, but the degree of freedom of this surgical method is less, and the working space is not very ideal. It often requires the operator to perform a large number of auxiliary actions to achieve a certain working space, thereby improving the surgical operation. The difficulty of the operation reduces the efficiency of the operation, and it also brings unnecessary additional damage to the patient. In response to this problem, with the development of robotic...
