A flexible/rigid sheath guiding mechanism, comprising a splitter (101), a guiding sleeve tube (102), a flexible sheath (103), a rigid sheath (104), and a handle (105). One end of the guiding sleeve tube (102) is fixed at an output of the splitter (101) and arranged coaxially with the output of the splitter (101); the other end of the guiding sleeve tube (102) is inserted into the rigid sheath (104); and the guiding sleeve tube (102) fits the rigid sheath (104). The handle (105) is constituted by a handle head (106) and a handle sleeve (107) fitted with each other. The splitter (101) is fixed within the handle head (106). The rigid sheath (104) is fixed on the handle sleeve (107). The soft sheath (103) runs through the guiding sleeve tube (104) and the rigid sheath (104), while an end of the soft sheath (103) is fixed at the output of the splitter (101). The guiding mechanism and an integrated all-around adjustable flexible/rigid endoscope thereof are provided with the characteristics of precise guiding, reliable positioning, simple structures, and convenient assembly. |
