For technicians in the technical field to which the present application belongs, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0049] See also Figures 3 to 7 This embodiment provides a bronchoscope joystick. The bronchoscope joystick is used to control the bronchoscope for detection, including manipulating the distal end of the bronchoscope to bend in different directions, manipulating the bronchoscope to take pictures, etc. The bronchoscope joystick is provided with a finger exoskeleton on the basis of the existing bronchial joystick, so that the burden of manipulating the bronchoscope joystick on the thumb can be reduced.

[0050] like Figure 3 As shown, the bronchoscope joystick includes: a joystick body 1 and a finger exoskeleton 2. The joystick body 1 includes a hand-held portion and an operating portion, the operating portion is arranged on the hand-held portion, and the operating portion includes a push button 12 operated by a thumb, and the push button is used to control the movement direction of the distal end of the bronchoscope.

[0051] The finger exoskeleton 2 at least includes a thumb exoskeleton 21. The thumb exoskeleton 21 can be sleeved on the thumb to assist the thumb in applying force to the push button.

[0052] Among them, the hand-held part and the operating part are an integrated structure, and the hand-held part and the operating part can be formed by enclosing and fixing more than two pieces of shells. For the convenience of operation, the operating part can be arranged above the hand-held part. The operating part is provided with the push button 12 and the photo button 13 for controlling the bronchoscope to take photos. The root of the push button 12 is connected to the operating part through a rotating structure 121, and the rotating structure includes two oppositely arranged rotating disks and a rotating shaft connecting the two rotating disks. The push button 12 can be pushed up and down by the thumb. When the push button 12 is pushed up, the distal end of the bronchoscope bends in one direction. When the push button 12 is pushed in another direction, the distal end of the bronchoscope bends in the opposite direction. Specifically, the distal end of the bronchoscope is provided with a bending part that can be bent in different directions. The push button 12 is connected to the bending part through a cable and controls the bending part to be directed in different directions. As Figure 2 As shown, when the push button 12 is pushed and rotated toward the A side, the curved portion at the end of the bronchoscope bends toward the A direction; when the push button 12 is pushed and rotated toward the B side, the curved portion at the end of the bronchoscope bends toward the B direction. The technology of how the push button 12 controls the curved portion at the distal end of the bronchoscope to bend in different directions is a prior art in the art, and this embodiment does not change the original structure of the bronchoscope itself, but only adds an exoskeleton that can assist the thumb in maintaining posture on the basis of the original structure, so the connection structure and control method of the push button 12 and the curved portion are not described in detail.

[0053] like Figure 3 and Figure 4As shown, the finger exoskeleton 2 includes not only a thumb exoskeleton 21, but also finger sleeves 22 that can be respectively mounted on other fingers such as the index finger and the middle finger. The four finger sleeves 22 and the thumb exoskeleton 21 are connected to the palm sleeve plate 213 to form a glove-like structure. The finger sleeves 22 can be made of flexible materials such as rubber and silicone, or can be made of fabrics such as cotton and linen.

[0054] like Figure 4 As shown, the thumb exoskeleton 21 includes a first joint 211 , a second joint 212 , a first force applying member 214 and a second force applying member 215 .

[0055] One end of the first joint 211 and one end of the second joint 212 are hinged through a hinge shaft 217; the first force-applying member 214 connects the first joint 211 and the second joint 212, and the first force-applying member 214 is used to control the movement or maintain the posture of the first joint 211; the second joint 212 and the palm cover 213 are hinged through a hinge shaft 218; the second force-applying member 215 connects the second joint 212 and the palm cover 213, and the second force-applying member 215 is used to control the movement or maintain the posture of the second joint.

[0056] The shape of the palm cover plate is adapted to the palm and can be worn on the palm. The palm cover plate 213 can be made of plastic, carbon fiber, etc. The palm cover plate 213 has a certain rigidity and can provide a certain force for the second force applying member 215. In order to facilitate the tightening and unfolding of the palm, the palm cover plate 213 can be formed by hingedly connecting two or more plates in sequence.

[0057] The first joint 211 is matched with the distal joint of the thumb, and the second joint 212 is matched with the second joint of the thumb. The first joint 211 and the second joint 212 are hollow structures, and the thumb can be inserted into the thumb exoskeleton 21, so that the distal joint of the thumb is located in the first joint 211, and the second joint of the thumb is located in the second joint 212. The first joint 211 and the second joint 212 can be made of aluminum, aluminum alloy or stainless steel, so the first joint 211 and the second joint 212 have a certain rigidity to assist the thumb in applying force to the push button 12.

[0058] When the thumb operates the push button, the second force-applying member 215 provides auxiliary force to the second joint 212, and the first force-applying member 214 provides auxiliary force to the first joint 211. Therefore, the first force-applying member 214 and the second force-applying member 215 can assist the first joint and the second joint of the thumb in applying force, thereby avoiding soreness caused by the thumb maintaining the same force-applying posture for a long time.

[0059] When performing bronchoscopic inspection, it is necessary to control the push button 12 to push up, push down or maintain a fixed posture. Therefore, in one embodiment, in order to assist the thumb to push up or push down the push button 12, the first force member 214 and the second force member 215 are small telescopic cylinders or small telescopic oil cylinders. When it is necessary to push the push button 12 up, the first force member 214 and the second force member 215 retract in a certain proportion to straighten the first joint 211 and the second joint 212 and push up; when it is necessary to push the push button 12 down, the first force member 214 and the second force member 215 extend in a certain proportion to bend the first joint 211 and the second joint 212 and push down. The first force member 214 and the second force member 215 are connected with a cable 216, which can be an electric wire, an air pipe or an oil pipe, etc. The cable 216 is used to provide a force medium for the first force member 214 and the second force member 215 or to control the working state of the first force member 214 and the second force member 215.

[0060] like Figure 5 As shown, in another embodiment, the first force applying member 214 and the second force applying member 215 are used for the first joint 211 and the second joint 212 to maintain a posture of applying force to the push button.

[0061] The first force-applying member 214 and the second force-applying member 215 include a cylinder body and a piston rod; a cavity is provided in the cylinder body, a piston adapted to the cavity is provided at one end of the piston rod, a valve is provided on the piston, and when the valve is opened, the piston rod can move relative to the cylinder body under the action of external force; when the valve is closed, the piston rod remains stationary relative to the cylinder body, so that the first joint and the second joint maintain their current postures.

[0062] like Figure 5The structure diagram of the first force-applying member 214 is shown. The first force-applying member 214 includes a cylinder body 2141 and a piston rod 2142. One end of the piston rod 2142 is provided with a piston 2143 adapted to the cavity, and a valve 2144 is provided on the piston 2143. The structure of the second force-applying member 215 is the same as that of the first force-applying member 214. During operation, the auxiliary thumb exoskeleton force can be turned on or off by controlling the valve 2144. When it is necessary to push the push button 12, the control valve 2144 is opened, and at this time, both sides of the piston are connected through the valve 2144, so that the piston rod can be extended and retracted with the movement of the thumb with very little resistance. When the thumb needs to be kept in a certain posture, the control valve 2144 is closed, and at this time, both sides of the piston are closed spaces, so that the piston rod is stationary relative to the cylinder body, so that the first joint 211 and the second joint 212 maintain a fixed posture, so that the force of the push button 12 acts on the thumb exoskeleton, and then the thumb can maintain the fixed posture without applying force. In one embodiment, in order to facilitate the control of the opening and closing of the valve, the finger exoskeleton also includes a button for controlling the opening or closing of the valve, and the button is arranged on the operating part. In the above embodiment, when the operator (i.e., the doctor) uses the bronchoscope for inspection, the operator controls it according to the inspection needs, and the bronchoscope does not need to automatically judge and control. When the operator needs to carefully observe a certain position of the bronchus during the inspection, the operator hopes that the push button 12 will remain in a certain posture for a long time. At this time, the operator controls the valve 2144 to close through the button; and when the doctor needs to inspect other positions, the doctor controls the valve 2144 to open through the button, and then pushes the push button 12 to control the distal bending of the bronchoscope. Therefore, in this embodiment, the valve 2144 can be controlled to open or close by the operator controlling the button.

[0063] In the above embodiment, the button for controlling the valve can be arranged on the operating part instead of on the exoskeleton. In the prior art, an operating part is arranged on the joystick of a bronchoscope or a bronchoscope, and the operating part has been provided with buttons with different functions such as a push button 12 and a photo taking button 13. In this embodiment, the structure of the button for controlling the valve is the same as that of the photo taking button 13, and the only difference is that the controlled object is different.

[0064] Furthermore, the valve 2144 can be a small-sized micro solenoid valve. The valve 2144 is connected to a 5V power supply through a power supply harness. The button for controlling the valve is connected in series in the power supply harness. The valve 2144 is controlled to be opened or closed by the button controlling the connection and disconnection between the valve 2144 and the 5V power supply. For example, when the valve 2144 is a normally open solenoid valve, when the button controls the valve 2144 to be connected to the 5V power supply, the valve 2144 is closed; and when the button controls the valve 2144 to be disconnected from the 5V power supply, the valve 2144 is opened. Conversely, when the valve 2144 is a normally closed solenoid valve, when the button controls the valve 2144 to be connected to the 5V power supply, the valve 2144 is opened; and when the button controls the valve 2144 to be disconnected from the 5V power supply, the valve 2144 is closed.

[0065] In one embodiment, in order to increase the auxiliary force provided by the first force applying member 214 and the second force applying member 215 when the valve is closed (i.e., a greater force is required to make the piston rod 2142 move relative to the cylinder body 2141), a resistance liquid is injected into the cavity of the cylinder body, and the resistance liquid is used to increase the relative movement resistance of the piston rod relative to the cylinder body when the valve is closed. The resistance liquid can be the hydraulic oil used in the existing hydraulic system.

[0066] like Figure 6 and Figure 7 As shown, when the first force-applying member 214 is extended, the resistance fluid flows toward the bottom of the cylinder along the direction indicated by the arrow in the cylinder body; when the first force-applying member 214 is contracted, the resistance fluid flows toward the head of the cylinder body (i.e., the end where the piston rod is located) along the direction indicated by the arrow in the cylinder body.

[0067] In another embodiment, a bronchoscope is provided, comprising a joystick and a display screen. The distal end of the bronchus is provided with a bending portion and a micro camera; the joystick is used to control the bending portion to bend in different directions and control the micro camera to take pictures; the display screen is used to display the images taken by the micro camera; the joystick is the bronchoscope joystick described in any one of the above embodiments.

[0068] In some embodiments, an ultrasound probe is also provided at the distal end of the bronchus. A button for controlling the operation of the ultrasound probe is provided on the joystick. In this embodiment, in addition to observing the inner wall of the trachea through the camera, the surrounding area of ​​the trachea can also be detected through the ultrasound probe, thereby making the detection more accurate and comprehensive.

[0069] The distal end of the bronchus may also be provided with a sampling assembly or a treatment component, the sampling assembly may include a puncture needle, and the treatment component may include laser, microwave, cryotherapy or high-frequency electrosurgical treatment. The ultrasonic probe may be used in conjunction with the sampling assembly or the treatment component.

[0070] For example, when CT scans show that there may be a problem at a certain location around the trachea, the doctor can extend the needle through the bronchus to the vicinity of that location, and then use ultrasound to detect and locate it. Once the positioning is complete, the doctor can guide the puncture needle from the inside of the trachea to the outside to remove the tissue or perform treatment.

[0071] In some other embodiments, the bronchoscope is a common bronchoscope that does not include an ultrasound probe.

[0072] The bronchoscope joystick in the above embodiment is additionally provided with a finger exoskeleton, which includes a thumb exoskeleton for assisting the thumb in applying force to the push button. The thumb exoskeleton can be mounted outside the thumb to keep the thumb in a posture of applying force to the push button, thereby greatly reducing the burden on the thumb during operation and also improving the operating efficiency and accuracy of the bronchoscope.

[0073] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
