DETAILED DESCRIPTION

[0027] The principles and features of the present application are described below, and the examples are only used to explain the present application, and are not used to limit the scope of the present application.

[0028] According to Figures 1 to 4As shown, the present application provides a ureteral catheter endoscope, comprising a mirror body and an operating handle 1, one end of the operating handle 1 is used for connecting with a control host 16, the other end is connected with the mirror body through a bendable catheter 2, a control assembly is connected on the operating handle 1, the control assembly is used for controlling the catheter 2 to bend, so as to adjust the detection field of view of the mirror body; A detection lens 13 is fixed on the mirror body, an optical fiber outlet 12 is arranged on the mirror body and located beside the detection lens 13, an optical fiber insertion assembly is fixed on the operating handle 1, and the optical fiber insertion assembly is communicated with the optical fiber outlet 12 through the catheter 2.

[0029] The embodiment integrates the endoscope display system and the laser stone crushing system, and the mirror body and the operating handle 1 are connected through the bendable catheter 2, the control assembly for controlling the bending of the catheter 2 is arranged in the operating handle 1, so that the detection lens 13 on the mirror body can realize multi-angle detection according to the bending angle of the catheter 2, and the detection range is expanded. When the stone disease is found, the stone crushing optical fiber is stretched out of the optical fiber outlet 12 through the optical fiber insertion assembly and the catheter 2, and the stone crushing is carried out on the position where the stone disease is found by the detection lens 13.

[0030] On the basis of the above technical scheme, the present application can also be improved as follows.

[0031] Preferably, in the embodiment, the control assembly comprises left and right turning assemblies 3 and front and back turning assemblies 4 which are independent of each other, and the left and right turning assemblies 3 and the front and back turning assemblies 4 control the left and right bending or the front and back bending of the catheter 2 respectively. The multi-directional bending of the catheter 2 is realized through the control assembly, and the detection range of the detection lens 13 is increased. Specifically, the left and right turning assemblies 3 and the front and back turning assemblies 4 can be controlled by an electric circuit or by a mechanical control. The electric circuit control can adopt conventional electronic control elements in the prior art.

[0032] Preferably, in the embodiment, taking the left and right turning assemblies 3 as an example, the left and right turning assemblies 3 comprise a first wrench 31 and two first turning gears 33, a first control wheel 32 is rotatably connected in the operating handle 1, the first wrench 31 is fixedly connected with the first control wheel 32, and the first control wheel 32 is meshed and driven with the two first turning gears 33 respectively, and two adjusting steel wires 34 are wound on the two first turning gears 33, and the two adjusting steel wires 34 are arranged along the length direction of the catheter 2 and are fixed on the left and right sides of the mirror body respectively.

[0033] The winding directions of the adjusting steel wires 34 on the two first turning gears 33 are opposite, the first control wheel 32 drives the two first turning gears 33 to rotate, one adjusting steel wire 34 is wound, and the other adjusting steel wire 34 is unwound, so that the catheter 2 bends towards the winding side of the adjusting steel wire 34.

[0034] According to Figure 3 As shown in the figure, only the engagement relationship between the first control wheel 32 and the two steering gears is shown, and it does not represent the specific position in the operating handle 1. The first wrench 31 is located on the outside of the control handle, and is used to control the rotation of the first control wheel 32. Due to the engagement relationship between the first control wheel 32 and the two first steering gears 33, when the first control wheel 32 rotates, the rotation directions of the two first steering gears 33 are the same. However, since the winding directions of the two adjusting steel wires 34 on the two first steering gears 33 are opposite, it is inevitable that one of the two adjusting steel wires 34 is wound and the other is unwound. The wound adjusting steel wire 34 drives the catheter 2 to bend towards the side through the connected mirror, and the other side of the catheter 2 corresponding to the bending side will be stretched to a certain extent. The unwound adjusting steel wire 34 is adapted to the bending of the catheter 2 through unwinding, so as to ensure that the catheter 2 is effectively bent towards the left and right sides. In addition, when setting, the two adjusting steel wires 34 on the first steering gear 33 and the second steering gear should be symmetrically arranged on the left and right sides of the catheter 2.

[0035] Preferably, in the embodiment, the front and rear steering assembly 4 comprises a second wrench and two second steering gears, and the operating handle 1 is rotatably connected with a second control wheel. The second wrench is fixedly connected with the second control wheel, and the second control wheel is in meshing transmission with the two second steering gears, respectively. The two second steering gears are wound with adjusting steel wires 34, and the two adjusting steel wires 34 are arranged along the length direction of the catheter 2 and are fixed to the front and rear sides of the mirror, respectively.

[0036] The winding directions of the two adjusting steel wires 34 on the two second steering gears are opposite, and the second control wheel drives the two second steering gears to rotate, one of the two adjusting steel wires 34 is wound, and the other is unwound, so that the catheter 2 bends towards the side where the adjusting steel wire 34 is wound. The working principle of the left and right steering assembly 3 is the same as the above, and the front and rear steering assembly 4 will not be described here. It should be noted that the left and right steering assembly 3 and the front and rear steering assembly 4 are independent of each other, and do not affect each other. When the catheter 2 bends towards the left and right sides, the actual length change of the front and rear sides of the catheter 2 can be ignored, and does not need to be wound or unwound by the adjusting steel wire 34 in the front and rear steering assembly 4.

[0037] Preferably, in the embodiment, the outer side of the catheter 2 is wrapped with a hose 15, and the adjusting steel wires 34 in the left and right steering assembly 3 and the front and rear steering assembly 4 are wrapped in the hose 15. Specifically, according to Figure 4As shown, the adjusting steel wire 34 is wrapped around the catheter 2 through the hose 15, so that when the left and right steering assembly 3 and the front and rear steering assembly 4 drive the corresponding adjusting steel wire 34 to be wound and unwound, the catheter 2 can be effectively bent, and the adjusting steel wire 34 is also protected from corrosion under the action of the environment, and then penetrates into the human body, causing the life safety of the human body to be threatened.

[0038] Preferably, in the embodiment, the operation handle 1 is also connected with a water inlet channel 8, which extends to the mirror body through the catheter 2, so as to flush and clean the surface of the detection lens 13, and keep the field of view of the detection lens 13 clear through flushing. Specifically, the water inlet channel 8 can be arranged to be inclined towards the detection lens 13 when passing through the catheter 2, so as to ensure the flushing effect on the detection lens 13. After flushing, the water can be discharged together with the gravel through the ureter after the gravel is broken.

Specifically, according to Figure 1 and Figure 2 As shown, the inclined connecting tube 5 can avoid excessive bending during the optical fiber insertion process.

[0040] Preferably, in the embodiment, the operation handle 1 and the catheter 2 are provided with three optical fiber channels 14, and the mirror body is provided with three optical fiber outlets 12 connected with the three optical fiber channels 14 respectively; the optical fiber insertion tube 6 is rotationally connected with the connecting tube 5, and the outer side wall of the optical fiber insertion tube 6 is also provided with an angle indicating line for displaying the connection state of the optical fiber insertion port 10 and any one of the optical fiber channels 14. According to the angle indicating line on the optical fiber insertion tube 6, it can be directly observed which one of the optical fiber channels 14 is connected with the optical fiber insertion port 10, so as to facilitate the operation of the operator.

[0041] Preferably, in the embodiment, three optical fiber outlets 12 are centered with the detection lens 13, and are respectively located at the three o'clock position, the six o'clock position and the nine o'clock position. According to the bending angle of the catheter 2, the detection lens 13 can be detected at multiple angles, and the three optical fiber channels 14 correspond to the left side, the right side and the front side of the detection lens 13, respectively. According to the position of the calculus, the optical fiber insertion tube 6 is rotated so that the optical fiber insertion port 10 is in communication with the optical fiber channel 14 close to the calculus, thereby improving the efficiency of lithotripsy. In the specific implementation process, the optical fiber insertion tube 6 is fixed with an insertion channel 11, the insertion channel 11 is an integral structure with the optical fiber insertion port 10, and the end of the insertion channel 11 away from the optical fiber insertion port 10 corresponds to the optical fiber channel 14. Through the rotation of the optical fiber insertion tube 6, the insertion channel 11 can be connected with any one of the optical fiber channels 14. The main function of the insertion channel 11 is to guide the lithotripsy optical fiber and shorten the distance between the optical fiber insertion port 10 and the optical fiber channel 14, so as to ensure that the lithotripsy optical fiber can smoothly enter the connected optical fiber channel 14 along the optical fiber insertion port 10 and the insertion channel 11.
