Instrument Boxes and Surgical Instruments

Abstract

The invention provides an instrument box and a surgical instrument. The instrument box includes a turning table assembly, two sets of driving wires, two wire rotation bodies and four output wires. Each group of driving wires includes two driving wires, each The two fixations formed by the set of driving wires on the inner rotating part are symmetrical about the first intersection point, and the four fixing points formed by the four driving wires on the inner rotating part are connected in turn to form a first parallelogram, and the first parallelogram The intersection point of the diagonal lines is the first intersection point. The other ends of the two driving wires in each group of driving wires are wound on the corresponding wire rotating body in the opposite direction, so that the turning table assembly is driven by the four driving wires, and then the output wire The movement of the turning table assembly is transmitted to the end instrument assembly, so that the end instrument assembly can move in multiple directions and with multiple degrees of freedom, which simplifies the design of the instrument box, reduces the volume of the instrument box, and improves the space utilization of the instrument box Rate.

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...
