Document Type and Number:
WIPO Patent Application WO/2020/248719
Kind Code:
A1
Abstract:
Disclosed is a pair of flexible medical scissors, comprising a main body (1), a lifting mechanism (3), an adjusting mechanism (4), a flexible sleeve (5), and a cutting mechanism (9). The lifting mechanism (3) is arranged at the top of a handle, and a finger sleeve (31) in the lifting mechanism (3) is sleeved on the ring finger of a user. When in use, the finger sleeve (31) is pulled to enable a pull string to pull a rotating shaft (12) such that the rotating shaft (12) drives a movable cutter (10) to rotate so as to realize a cutting function. The adjusting mechanism (4) is arranged at the bottom of the handle, the adjusting mechanism (4) is internally provided with three groups of sliding slots (42), and a sliding post (44) is provided in the sliding slots (42). When the sliding post (44) slides to different positions and is fixed in a clamp slot (43), a pull wire (45) is used to pull three groups of movable shafts (467) in an adjusting plate (46), such that the flexible sleeve (5) can be bent at different angles, and a spring (20) in the cutting mechanism (9) is controlled by a telescopic pull wire (21) so that the length of the cutting mechanism (9) can be controlled so as to conveniently enter the body of a patient via an operation channel. An adjusting disk (19) is mounted at an upper end of the cutting mechanism (9), and the user can pull a connection wire according to an angle so that all-around multi-angle adjustment for the cutting mechanism (9) can be adjusted.
