Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present application.

[0023] Please refer to Figures 1 to 4 The present application provides a technical solution:

[0024] Embodiment 1: A fiber bronchoscope capable of accurate drug delivery, comprising a bronchoscope 1, one end of the bronchoscope 1 being connected to a catheter 6, an end of the catheter 6 being provided with a lens 7 for detection, the end of the catheter 6 being in communication with the inner cavity of the lens 7, the lens 7 being provided with a lens groove 9 for mounting a lens, and the catheter 6 being inserted with a light guide beam connected to the lens.

[0025] By setting the lens and the light guide beam, the catheter 6 is inserted into the lung, and the purpose of visual detection is achieved.

[0026] The outer end of the bronchoscope 1 is provided with a pipe inlet 3, the pipe inlet 3 being in communication with the catheter 6 and being inserted with a drug inlet pipe 4, one end of the drug inlet pipe 4 extending to the outside of the lens 7 and being connected with a spray head 8, the other end of the drug inlet pipe 4 being provided with a drug pump 5, and the end of the catheter 6 away from the lens 7 being provided with a propulsion assembly for driving the drug inlet pipe 4 to extend inside the catheter 6.

[0027] By setting the drug inlet pipe 4, the purpose of directly administering medicine through the bronchoscope 1 is achieved, the drug pump 5 and the spray head 8 are used in cooperation, so that the liquid medicine is sprayed at the lesion position, the problem of poor flow caused by the small inner diameter of the drug inlet pipe 4 is avoided by using the pressurized spraying method, and the propulsion assembly is used to achieve the purpose of adjusting and installing the drug inlet pipe 4, so that the spray head 8 is directly opposite the lesion position, and the purpose of accurate drug delivery is achieved.

[0028] Embodiment 2: Based on embodiment 1, a long strip-shaped opening groove 14 is arranged on the outer wall of the catheter 6, and the inner side of the opening groove 14 is directly opposite the drug inlet pipe 4.

[0029] By setting the opening groove 14, the outer wall of the drug inlet pipe 4 is exposed, and the propulsion driving is facilitated.

[0030] The advancing assembly is installed at the position of the open slot 14, the advancing assembly comprises a fixed ring 10, an extended half pipe 11 and an arc-shaped pressing plate 13, the fixed ring 10 is fixedly sleeved on the catheter 6, and the fixed ring 10 is located at one end of the open slot 14, the extended half pipe 11 extends in parallel along the open slot 14, and one end of the extended half pipe 11 is fixed on the fixed ring 10, the arc-shaped pressing plate 13 is elastically and slidably installed at the upper end of the extended half pipe 11, the extended half pipe 11 is located at the lower end of the open slot 14, and the upper end of the extended half pipe 11 is symmetrically provided with long grooves 12 on both sides, the lower end of the arc-shaped pressing plate 13 is opposite to the open slot 14, and a pair of second elastic bands 16 are arranged on both sides of the arc-shaped pressing plate 13, the second elastic bands 16 pass through the long grooves 12 and extend to the lower end, and the end portions of the second elastic bands 16 located at the lower end of the long groove 12 are provided with sliding blocks, and the sliding blocks are attached to the outer wall of the lower end of the long groove 12.

[0031] By arranging the extended half pipe 11 and the long groove 12, the sliding length of the arc-shaped pressing plate 13 is limited, so that the arc-shaped pressing plate 13 can only slide on the extended half pipe 11. Since the inner diameter of the catheter 6 is small, and the inner diameter of the medicine inlet pipe 4 is smaller, the medicine inlet pipe 4 is prone to deviation during insertion. Once the deviation occurs, the medicine inlet pipe 4 is easily bent, which causes the insertion to be stuck. Therefore, during the installation process, the arc-shaped pressing plate 13 is manually pressed to press the exposed outer wall of the medicine inlet pipe 4 of the open slot 14. Through the pressing and sliding of the arc-shaped pressing plate 13, the position of the medicine inlet pipe 4 in the catheter 6 is achieved. Then, the arc-shaped pressing plate 13 is loosened to fall off the medicine inlet pipe 4 and reset to the end close to the fixed ring 10. In this way, the medicine inlet pipe 4 is accurately and stably inserted and extended. During the medicine feeding process, the length of the medicine inlet pipe 4 is adjusted through the above operation, so that the position of the nozzle 8 is controlled, and the nozzle 8 accurately corresponds to the lesion position for treatment.

[0032] In example 3, a screw hole is arranged on the fixed ring 10, and a fastening bolt is threadedly installed in the screw hole and pressed on the outer wall of the catheter 6.

[0033] The fastening bolt is arranged to fixedly install the fixed ring 10 on the catheter 6.

[0034] The inner diameter of the arc-shaped pressing plate 13 is smaller than the outer diameter of the catheter 6, the inner diameter of the semicircle surrounded by the arc-shaped pressing plate 13 and the pair of second elastic bands 16 is greater than the outer diameter of the catheter 6, the side of the arc-shaped pressing plate 13 close to the fixed ring 10 is provided with a first elastic band 15, and the two ends of the first elastic band 15 are fixed on the arc-shaped pressing plate 13 and the fixed ring 10, respectively.

[0035] By setting the first elastic band 15, the first elastic band 15 is stretched by setting the arc-shaped pressing plate 13 to press and advance a certain distance, after the advancement is completed, the arc-shaped pressing plate 13 is released, and the arc-shaped pressing plate 13 is automatically reset under the reset elastic force of the first elastic band 15, by limiting the inner diameter size of the arc-shaped pressing plate 13, so that the arc-shaped pressing plate 13 is separated from the medicine feeding tube 4 after the arc-shaped pressing plate 13 is released, and the reset is realized.

[0036] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
