Thefirst channel 90 has the configuration shown in FIG. 7 and is used to deliver an end of a sputum aspirator brush or biopsy forceps to the forward end of theprobe 50 for sputum removal or sampling. Thefirst channel 90 is offset relative to thelight source 52 and thecamera 51. Thefirst channel 90 communicates with theinsertion port 21 and penetrates thehandle 20, theinsertion tube 10, and theprobe 50 in this order. A sputum brush or biopsy forceps is inserted into thefirst channel 90 through theinsertion opening 21 in thehandle 20. The insertion opening and thefirst channel 90 are arranged, so that the function of the bronchoscope is improved, the bronchoscope is more convenient to use, and the application range is wider.

Preferably, thesteering control mechanism 60 further comprises a biomimetic joint 64, as shown in fig. 9, the biomimetic joint 64 being disposed within theinsertion tube 10 and having theprobe 50 mounted at one end thereof as previously described. Each of thetraction ropes 63 penetrates the bionic joint 64 and is fixed to one end of the bionic joint 64, at which theprobe 50 is mounted.Different traction ropes 63 pull different positions of the end part (the end where theprobe 50 is installed) of the bionic joint 64 along the circumferential direction, so that the bionic joint 64 is bent to drive theprobe 50 to perform various actions as described above. Theinsertion tube 10 is of a flexible structure, and theinsertion tube 10 is bent when the bionic joint 64 is bent. In addition, the bionic joint 64 does not enlarge the volume of theinsertion tube 10, and has a simple structure and convenient driving.

The specific configuration of the biomimetic joint 64 is described below with reference to fig. 10 and 11. Fig. 10 shows a singlejoint element 641 andfirst channel 90. Fig. 11 shows a partially enlarged view of thejoint members 641 abutting in sequence along theinsertion tube 10.

As shown in fig. 10, thearticular component 641 includes atraction ring 6411, aprojection 6412, a first through-hole 6413, and a first central through-hole 6414. The pullingring 6411 is ring-shaped, and the outer wall of the pullingring 6411 is fitted to the inner wall of theinsertion tube 10. Theprotrusions 6412 are provided on one side end surface of thepull ring 6411, protrude in the direction of theprobe 50, and are preferably two in number and symmetrically arranged. Theconvex portions 6412 abut against thedrag ring 6411 of the next joint 641, and theconvex portions 6412 of two vertically adjacent joint 641 are circumferentially displaced from each other.

The first throughholes 6413 are through holes of the pullingring 6411, and are uniformly distributed along the circumference of the pullingring 6411 for the pullingrope 63 to pass through. Therefore, the number of thefirst perforation 6413 is the same as the number of thetraction rope 63. The number of theprojections 6412 is less than the number of the first throughholes 6413. The first throughholes 6413 of the upper and lower adjacentjoint elements 641 correspond in position to form a straight passage (second passage) for thetraction rope 63 to pass through.

As shown in fig. 12, each first central throughhole 6414 forms a straight passage (third passage) through which theintermediate line 40 and thefirst passage 90 pass. The arrangement of the first to third channels can effectively prevent thetraction ropes 63 and theintermediate wire 40 from self-winding and mutual winding, so that thetraction ropes 63 and theintermediate wire 40 work orderly without mutual interference, and thetraction ropes 63 can drive the bionic joint 64 conveniently.

In operation, when onetraction rope 63 is pulled, the positions of thejoint members 641 where thetraction rope 63 passes without theconvex portions 6412 approach each other, so that the length of the whole bionic joint 64 corresponding to the position of thetraction rope 63 is shortened, and the lengths of other positions are unchanged, thereby bending the bionic joint 64.

By analogy,different traction ropes 63 can be pulled to drive the bionic joint 64 to form different bends, so that theprobe 50 can rotate for 360 degrees. It should be appreciated that the number ofpull cords 63 orprotrusions 6412 may be set according to the actual situation and the specific design requirements.

In the present invention, preferably, the two ends of the bionic joint 64 are respectively provided with mountingsleeves 701 and 702 (see fig. 9), the mountingsleeves 701 and 702 have the same structure and are symmetrically arranged, and the outer walls of the mountingsleeves 701 and 702 are respectively matched with the inner wall of theinsertion tube 10. As shown in fig. 13, the end surfaces 71 of the mountingsleeves 701 and 702 are formed with a second center throughhole 711 and a plurality of second throughholes 712. The second central throughhole 711 corresponds to the first central throughhole 6414 of thejoint member 641 for themiddle line 40 and thefirst passage 90 to pass through. The second throughhole 712 corresponds to the first throughhole 6413 of thejoint member 641 for thedrawing string 63 to pass through. During installation, thepull cords 63 are sequentially inserted through the second throughholes 712 of the mountingsleeve 701, the first throughholes 6413 of the pull rings 6411, and the second throughholes 712 of the mountingsleeve 702, and finally, the ends of thepull cords 63 are fixed to the mountingsleeve 702.

The end of thetraction sheath 80 is fixed to the mountingplate 71 of the mountingsleeve 701, that is, thetraction sheath 80 does not enter the biomimetic joint 64.

Themiddle wire 40 passes through the second central throughhole 711 in the mountingsleeve 701, the first central throughhole 6414 in each pullingring 6411, and the second central throughhole 711 in the mountingsleeve 702 in sequence, and is electrically and communicatively connected to thelight wire 521 and thecamera 51. The utility model discloses aninstallation sleeve 701, 702 and eachpull ring 6411 form the dedicated passage of eachhaulage rope 63 andintermediate line 40, its simple structure, and can preventhaulage rope 63 andintermediate line 40 intertwine. It is understood that in other embodiments of the present application, thefirst channel 90 may be formed in other manners, and is not limited thereto.
