Specifically, the operating unit 1100 is configured to receive position instructions and/or speed instructions, and feed back position information and/or speed information to the control terminal 4. The control terminal 4 may specifically include a posture and position control module 41 for performing master-slave mapping calculations on the received position information and/or speed information to respectively calculate the desired position and position of the end of the bronchoscope 5 /Or the speed, and control the actuator 21 accordingly to drive the bronchoscope 5 to rotate and/or move to a desired position at a desired speed, so that the end of the bronchoscope 5 reaches the desired posture in the human body.

In the present invention, there is no particular limitation on the type and size of the bronchoscope 5. Please refer to FIG. 9, which shows a bronchoscope 5. In this embodiment, the bronchoscope 5 is a flexible bronchoscope, and includes a bronchoscope body 51, a catheter 52, an injection tube 53, a suction tube 54 and a catheter drive knob 56. Preferably, the bronchoscope 5 further includes a suction valve switch 35. The catheter 52 is used to be inserted into target tissues such as the lungs and bronchus of the patient to provide operating channels for other components. For example, the catheter 52 includes an observation channel, and the operator can observe the lesion of the target tissue through a lens in the observation channel. The catheter 52 may also include a functional channel communicating with the injection tube 53 for performing surgical operations such as perfusion and biopsy. For example, the operator injects liquid (such as saline or liquid medicine, etc.) into the distal end of the catheter 52 through the injection tube 53, and the liquid flows into the patient's lungs to achieve surgical operations such as bronchoalveolar lavage. In addition, the functional channel can also communicate with the suction tube 54 through which liquid can be sucked from the distal end of the catheter 52 to suck the fluid in the patient's body. The suction valve switch 35 can control the opening and closing of the suction tube 54 to realize the control of the suction liquid. Generally, the operator needs to turn on the suction by pressing the suction valve switch 35. The catheter drive knob 56 is used to drive the distal end of the catheter 52 to swing, and the operator can adjust the swing direction of the distal end of the catheter 52 by rotating the catheter drive knob 56. In addition, the functional channel can also provide a channel through which other instruments (such as biopsy forceps) pass. In the use of the existing bronchoscope 5, the operator holds the bronchoscope body 51 and manipulates the bronchoscope 5 to be delivered forward and backward to the distal end, so that the catheter 52 is moved forward and backward in the axial direction, so that the distal end of the catheter 52 is in the target tissue of the patient. Advance and retreat; the operator can also manipulate the bronchoscope 5 to rotate circumferentially within a range of ±120° around the axis, so that the distal end of the catheter 52 can be rotated circumferentially in the target tissue of the patient to achieve the distal end of the catheter 52 The position is adjusted; the operator 32 operates the catheter drive knob 56 to swing the distal end of the catheter 52 in the target tissue of the patient. In this way, the adjustment of the distal end posture of the catheter 52 is realized.

In this embodiment, in order to adjust the posture and position of the end of the bronchoscope 5, as shown in FIG. 4, the actuator 21 may include a rotation joint 211, a moving joint 212, and a rotation joint 154 (shown in FIG. Also called a transmission shaft), the rotation joint 211 is used to realize the rotation of the bronchoscope 5, the moving joint 212 is used to realize the movement of the bronchoscope 5, and the rotation joint 154 is used to drive the catheter drive knob of the bronchoscope 5 56 to achieve the end of the bronchoscope rotation. Correspondingly, the slave terminal 2 also includes three drivers that are communicatively connected with the control terminal 4 for driving the rotation joint 211, the moving joint 212, and the rotation joint 154 to move. That is, the driver includes a rotation driver, which is used to drive the rotation of the rotation joint 211; a mobile driver, which is used to drive the mobile joint 212 to move; and a rotation driver, which is used to drive the rotation joint to rotate. As shown in Fig. 3, the slave end 2 further includes a mobile trolley 23 and a fixed bracket 22 arranged on the mobile trolley. The actuator 21 can support and adjust the position of the bronchoscope 5 through the fixed bracket 22, and adjust the position of the bronchoscope 5 through the moving trolley 23.

In this embodiment, the operating unit 1100 can provide a variety of inputs for the control terminal 4 and combine the above-mentioned different master-slave control modes to adapt to the doctor's operation requirements in different scenarios.

In one embodiment, the operating unit 1100 may include an operating handle 1110, and the operating handle 1110 includes a housing and an operating member movable relative to the housing. The operating member is used to remotely operate the execution driving member 21 to move. The operating member may be one or more. When there is one operating element, it has three degrees of freedom, such as a spherical hinge, which is used to establish a master-slave mapping relationship with the three joints of the actuator 21. There may also be two operating parts, namely a rotation control part and a movement control part. The rotation control member includes two degrees of freedom, such as a Hooke hinge, a trackball or a game joystick, and establishes a master-slave mapping relationship with the rotation joint 211 and the rotation joint of the actuator 21, respectively. The movement control part establishes a master-slave mapping relationship with the movement joint 212 of the execution driving part 21. There may also be three operating elements, which are used to establish a master-slave mapping relationship with the three joints of the actuator 21 respectively.

The inventor found that the rotation and bending angle range of the bronchoscope is determined, for example, the rotation range is plus or minus 120 degrees, the bending angle range is plus or minus 170 degrees, and the absolute position of the bronchoscope bending and rotation movement is related to the input of the operating unit 1100 It can be corresponded, it is convenient for the doctor to accurately control the end posture of the bronchoscope, and then can control the movement direction of the bronchoscope in the narrow organ lumen (such as the airway lumen). However, for the forward and backward movement of the bronchoscope, since the forward and backward movement is manually pushed by the doctor, there is no absolute range of motion. Therefore, for the front and back movement of the bronchoscope, the relative displacement needs to be controlled. Through speed mapping control, the relative displacement control of forward and backward movement can be realized. Therefore, in some embodiments, the master-slave control mode of position mapping and speed mapping is adopted between the operation handle 1110 and the execution driver 21, that is, the attitude and position control module 41 controls the movement of the operation handle 1110. The speed information is subjected to master-slave mapping calculation to calculate the expected moving speed of the end of the bronchoscope, and the rotation angle information of the operating handle 1110 is subjected to master-slave mapping calculation to calculate the expected rotation of the bronchoscope The angle, in this way, the movement of the driving member 21 is controlled.

Specifically, the operating element includes a rotation control element and a movement control element as an example. The operating handle 1110 also includes a position sensor and a speed sensor. The position sensor is communicatively connected with the control terminal 4, and is used to obtain the rotation angle of the rotation control member. The speed sensor is communicatively connected with the control terminal 4, and is used to obtain the moving speed of the moving control member. The posture and position control module 41 of the control terminal 4 receives the rotation angle of the rotation control member, the movement speed of the mobile control member, and the preset master-slave mapping ratio (that is, the position mapping ratio and the speed mapping ratio), Perform master-slave mapping calculation to obtain the desired position of the rotation joint 211, the desired position of the rotation joint, the desired speed of the moving joint 212, and control the rotation driver, the mobile driver and the rotation driver to drive the corresponding joint to move at the desired position and speed .

In the above embodiment, the position and speed of the control member are directly acquired through various types of sensors. In other embodiments, the position and speed of the control member are obtained indirectly by obtaining other physical quantities. For example, the operating member includes a pressure-sensitive button (such as a pressure-sensitive button) and a pressure sensor. At this time, the posture and position control module 41 of the control terminal 4, according to the received pressure sensitivity information (such as pressure sensitivity size, pressure sensitivity change speed, etc.), presets the calibration relationship between the position, speed and pressure sensitivity information and The master-slave end maps the ratio to obtain the desired position and speed of each joint at the slave end, and then controls the rotation drive, the mobile drive and the rotation drive to drive the corresponding joint movement.

In another embodiment, the operating unit 1100 includes an interactive interface 1120. As shown in FIG. 7, the interactive interface 1120 includes a catheter forward button 1121, a catheter back button 1122, an upward bending button 1123, a downward bending button 1124, a left rotation button 1125, and a right rotation button 1126. The catheter extension button 1121 is used to drive the bronchoscope to move distally, the catheter retreat button 1122 is used to drive the bronchoscope to move proximally, and the upward bending button 1123 is used to drive the end of the bronchoscope to bend upward. The downward bending button 1124 is used to drive the end of the bronchoscope to bend downward, the left rotation button 1125 is used to drive the bronchoscope to rotate to the left, and the right rotation button 1126 is used to drive the bronchoscope to rotate to the right. Those skilled in the art should understand that up and down and left and right here are only used to describe the relationship between the movement direction of each key when driving the bronchoscope to move, and does not constitute a limitation on the function of the key. In this embodiment, the buttons may be physical buttons or virtual buttons. In some embodiments, a master-slave control mode of speed mapping is adopted between the interactive interface 1120 and the execution driver 21. That is, the posture and position control module 41 performs master-slave mapping calculation on the speed information corresponding to each button on the interactive interface 1120 and the speed mapping ratio to calculate the desired speed of the end of the bronchoscope. To control the movement of the driving member 21.

Specifically, the upward bending button 1123, downward bending button 1124, the left rotation button 1125 and the right rotation button 1126 accept external commands through speed mapping to realize the control of the rotation speed of the rotation joint 211 and the rotation joint, thereby achieving Control of the posture of the end of the bronchoscope; through the catheter forward button 1121, the catheter back button 1122 accepts external instructions to control the moving speed of the moving joint 212 through speed mapping, thereby realizing the control of the position of the end of the bronchoscope. Furthermore, the speed information corresponding to each button can be preset. The preset speed corresponding to each key can be the same or different. After the aforementioned button accepts the instruction, the posture and position control module 41 obtains the desired speed according to the preset speed mapping ratio and the preset speed. For example, the operator selects the catheter forward button 1121 on the interactive interface 1120, and the button sends a message to the posture and position control module 41. The posture and position control module 41 obtains the desired extension speed according to the preset speed mapping ratio and the preset extension speed, and then controls the moving driver to drive the moving joint to make the bronchoscope 5 extend at the desired speed. Further, the interactive interface also includes a speed selection button, which is communicatively connected with the posture and position control module 41 for adjusting the speed mapping ratio, so that each joint can move at a faster or slower speed.

In another embodiment, the operating unit 1100 includes both an operating handle 1110 and an interactive interface 1120. The operator can select the operating handle 1110 or the interactive interface 1120 according to needs and combine different master-slave control modes to remotely operate the driving member 21.

In order to drive the bronchoscope 5 to perform surgical operations such as perfusion and suction, the slave end 2 further includes a suction device 8 and a lavage fluid delivery device 9. In addition, the lavage fluid delivery device 9 is in communication with the injection tube 53, and is used to deliver the perfusion fluid to the target tissue of the human body. The suction device 8 is in communication with the suction tube 54 and is used to draw the effusion in the human body out of the body. The control terminal 4 also includes a perfusion and suction control module 43, which is communicatively connected with the suction device 8 and the lavage fluid delivery device 9 to control the opening of the suction device 8 and the lavage fluid delivery device 9, and And operating parameters. Correspondingly, the operating unit 1100 is provided with a lavage fluid delivery button and a suction button, which are communicatively connected with the perfusion and aspiration control module 43 for receiving perfusion or aspiration instructions. Preferably, the lavage fluid delivery button and the suction button are arranged on the operating unit 1100 for easy operation. Of course, the operating unit 1100 may also include general keys. When the control terminal 4 senses that the suction device 8 and the lavage fluid delivery device 9 are connected to the control terminal 4, the control terminal 4 maps the general keys to receive instructions for perfusion or suction. In another embodiment, the interactive interface 1120 includes a suction button 1127 and a sampling button 1128. Similarly, the sputum suction button 1127 and the sampling button 1128 are communicatively connected with the perfusion and suction control module 43 for receiving sputum suction or sampling instructions.

In order to avoid errors in the master-slave control, in this embodiment, the control terminal 4 also includes a safety control module, which is used for position, speed and/or trajectory safety detection, such as position deviation detection, speed overrun detection , Detection of the difference between the actual speed and the desired speed, etc. Specifically, the master terminal 1 also includes an alarm device. The alarm device may be a signal lamp, a buzzer or a warning message on an interactive interface. And for different error reports, different error reporting methods can be used, such as flashing signal lights, buzzer sounds of different frequencies, interactive interface information prompts, and so on. The actuator 21 further includes sensors for measuring the position and/or speed of each joint. The safety control module is communicatively connected with sensors to monitor whether the position and speed of each joint of the actuator 21 are matched with the expected position and the expected speed, and whether the trajectory of the bronchoscope matches the expected trajectory. If it does not match, the safety control module controls the alarm device of the master terminal 1 to report an error.

Please continue to refer to FIG. 2 in conjunction with FIG. 1. In this embodiment, the master terminal 1 further includes a display unit 1300, the display unit 1300 is communicatively connected to the control terminal 4, and the display unit 1300 is used to display the master terminal interface. Figure 7 illustrates a main interface display diagram during surgical operation. The interactive interface 1120 is set on the main terminal interface. In addition, the main terminal interface can also display surgical images. Correspondingly, the control terminal 4 further includes an image signal processing and transmission module 42, which is communicatively connected with the bronchoscope 5 to receive information about the surgical environment (such as surgical instruments) from the bronchoscope 5 , Target lesions, tissues and organs and surrounding tissues and organs, blood vessels) image signals, and perform image processing such as denoising and sharpening on the image signals. Further, the image signal processing and transmission module 42 is also communicatively connected with the display unit, so that the display unit displays an image according to the processed image signal, so that the operator can be based on the image captured by the bronchoscope 5 The image signal performs the next operation, such as controlling various components to adjust the position of the bronchoscope 5. The interactive interface 1120 may be displayed superimposed on the surgical image, or may be displayed separately in different areas of the main terminal interface.

In order to enable the execution driver 21 and the operation unit 1100 to realize master-slave mapping, in this embodiment, the posture planned by the operation unit 1100 and when the control master interface is in a locked state (the user cannot log in) is set The positions are all at the initial zero position. In this way, after the master control interface is unlocked, the end of the execution driver 21 will follow its posture and position, and its posture and position will also be at the initial zero position. That is to say, by default, the initial postures of the operating unit 1100 and the execution driving member are both at the initial zero position. In order to avoid misoperation, preferably, in this embodiment, the master terminal 1 further includes a sensing unit, which is used for user login detection, specifically, for detecting whether there is an operator, and according to the detection As a result, the operating unit 1100 is locked or unlocked. The sensing unit may be, for example, a photoelectric switch, and is provided on the display unit 1300. In the power-on state, if the presence of an operator is detected within the detection range of the photoelectric switch, the operating unit 1100 can perform master-slave control operations; if the presence of the operator is not detected, the operating unit 1100 will be in a system lock state . Further, in the pre-operative operation preparation stage, the operation unit 1100 may be unlocked to allow the doctor to perform operations according to whether the slave terminal 2 has completed the operation confirmation.

As shown in Figure 3, the process of user login detection through the sensing unit specifically includes the following steps:

S11, when logging in to the control master interface, the sensing unit detects whether there is an operator, if yes, execute step S12, if not, execute step S13;

S12, confirm whether the slave 2 has completed the operation, if yes, execute step S14, if not, execute S13;

S13, the control master interface is in a locked state;

S14, the control main terminal interface is in an operable state, and the user can perform operations.

In some embodiments, please continue to refer to FIG. 2 in conjunction with FIG. 3. The execution driving member 21 further includes an inner cavity and an adapter 24, and the adapter 24 is detachably disposed in the inner cavity for attaching The bronchoscopes 5 of different models are fixed to the actuator 21, so that the surgical robot provided by the present invention can be adapted to the bronchoscopes 5 of different models on the market. That is, in order to adapt to different types of bronchoscopes, different adapters can be replaced to match bronchoscopes with different sizes, different shapes, different control modes, and different identification and encryption chips; of course, fine-tuning adapters can also be used in implementation , To adjust the gap size of the lens holding device, to adapt to different sizes of bronchoscopes, and to ensure that the lens holding mirror is installed firmly.

In order to establish a master-slave mapping relationship between the operating unit 1100 and the end of the execution driver 21, the slave end 2 further includes an information collection unit (for example, a sensor, an encryption chip, etc.), and the information collection unit is arranged at On the adapter 24, the information collection unit is used to record the man-machine interaction and control parameter information of the bronchoscope 5. The human-computer interaction and control parameter information is used to match the master-slave control mapping relationship between the master terminal 1 and the execution driver 21, for example, the motion ranges of different bronchoscopes 5 in three directions, the master-slave terminal The mapping ratio of speed and/or position, the preset speed of each button when the interactive interface 1120 is used as an operating unit, and so on. In another embodiment, the information collection unit is used to record only the type of the bronchoscope 5. The control terminal 4 includes a memory, and the memory includes a bronchoscope parameter database of information such as bronchoscope type, human-computer interaction, and control parameter information. After the control terminal 4 obtains the type of the bronchoscope 5 from the information collection unit, it searches for the corresponding human-computer interaction and control parameter information from the bronchoscope parameter database. If there is no matching data in the bronchoscope parameter database, the control terminal 4 controls the relevant equipment to issue an alarm that the bronchoscope 5 is not compatible, and the type of bronchoscope 5, human-computer interaction and control parameter information need to be written into the bronchoscope Parameter database.

Based on this, after the bronchoscope 5 is connected to the slave end 2 and the entire master end 1 is activated, the self-checking of the bronchoscope 5 is performed first, that is, the bronchoscope is obtained while detecting whether each joint moves normally. Mirror 5's human-computer interaction and control parameter information. Specifically, the control terminal 4 first recognizes the type of the bronchoscope 5 connected to the slave terminal 2, and if the type of the bronchoscope 5 can be recognized, it retrieves the information of the type of bronchoscope 5 recorded by the information collection unit. The human-computer interaction and control parameter information are described, and the master-slave control mapping relationship is matched; if the type of the bronchoscope 5 cannot be recognized, an interactive prompt is used to prompt the operator that the bronchoscope 5 is unrecognizable and the bronchoscope 5 needs to be replaced. Wherein, before the recognition of the type of the bronchoscope 5 is realized, the information of the bronchoscope 5 may be stored in the control terminal 4. Only when the information of the bronchoscope 5 connected to the slave end 2 has been stored in the control end 4, the type of the bronchoscope 5 can be identified. As shown in Figure 4, the self-checking of the bronchoscope 5 card connection specifically includes the following steps:

S21: Identify the type of the bronchoscope 5 connected to the slave 2; if it can be identified, then perform step S22; if it cannot be identified, then perform step S23;

S22: Acquire the human-computer interaction and control parameter information of this type of bronchoscope 5, and then complete the master-slave control mapping relationship between the master terminal 1 and the execution driver 21;

S23, indicating that bronchoscopy 5 is not available.

The following takes the operation handle control combined with the absolute posture matching master-slave control as an example to describe the operation process in detail.

In the surgical preparation stage, before the completion of the operation confirmation, the main control interface is in a locked state, that is, an inoperable state. The bending/rotating posture operation buttons of the handle and the forward and backward movement operation buttons automatically return to the initial zero position by default. After the bronchoscope 5 is connected, the control terminal 4 performs self-checking and encryption chip recognition, and then controls each joint of the slave terminal 2 to follow the posture, so that the posture of the robot slave terminal 2 is consistent with the initial posture of the master terminal 1.

After the preparation for the operation is completed, the operation is confirmed. After that, the operating handle 1110 can enter the operating state. During the operation of the doctor, according to the real-time feedback of the bending/rotation position sensing analog input signal of the operating handle 1110, and after the master-slave mapping calculation, the desired command position of the robot from the end 2 to bend up and down and rotate left and right is obtained, and then the robot is controlled From the end 2 to complete the corresponding up and down bending and left and right rotation movement. Similarly, according to the forward and backward movement speed sensor analog input signal fed back by the operating handle 1110 in real time, and after the master-slave mapping calculation, the expected command speed direction and magnitude of the robot's forward and backward movement are obtained, and then the robot is controlled from the end 2 to complete the corresponding forward and backward movement. .

By operating the handle 1110, the end of the bronchoscope 5 can be moved back and forth, bend up and down, and rotate left and right in the respiratory tract, and reach the lesion position in the upper/lower respiratory tract. Then, click the switch button of the operating handle 1110 to open the alveolar toilet fluid valve to wash the patient's alveoli. Each time you click to trigger the toilet liquid activation button, a specific volume of toilet liquid, such as 10ml, will be output. After completing the alveolar washing, click the 1110 toilet wash collection button on the operating handle to activate the negative pressure switch to start toilet liquid collection; in the same way, click the 1110 suction function button on the operating handle 1110 to activate the negative pressure switch, and the patient can suck sputum operation treatment.

Similarly, if the master-slave control mode of interactive interface control and speed control is adopted, after the bronchoscope 5 is installed and the operation is confirmed, the doctor can operate the corresponding control buttons on the interactive interface to control the bronchoscope 5 robot in the speed control mode. Three degrees of freedom, such as forward and backward movement, up and down bending, and left and right rotation, are controlled. Similarly, doctors can perform surgical diagnosis and treatment operations such as washing/sampling/sputum suction through the interactive interface.

The doctor can select the first master-slave control mode or the second master-slave control mode according to actual needs, or use both together.

As shown in FIG. 6, the master-slave mapping control logic of the surgical robot system provided in this embodiment is roughly as follows:

(11) The control terminal 4 establishes the operation unit 1100 and the execution unit 1100 according to the human-computer interaction and control parameter information of the bronchoscope 5 recorded by the information collection unit provided on the adapter 24 The master-slave mapping control relationship at the end of the driver 21;

(12) The control terminal 4 plans the command position and command speed of the end of the execution driver 21 according to the position/speed sensor information of the operating unit 1100, and controls the station according to the command position and the command speed. The related joints of the execution driving member 21 are described, so that the end of the execution driving member 21 can follow the posture and position.

As shown in FIG. 8, when the surgical robot system provided in this embodiment is used for airway detection, the general process is as follows:

(21) The master terminal 1 is started;

(22) Bronchoscope 5 self-checking;

(23) User login detection;

(24) Complete the setup and preoperative confirmation of the slave end 2;

(25) Remotely manipulate the end of the bronchoscope 5 through the main end 1, so that the end of the bronchoscope 5 reaches the respiratory tract lesion;

(26) Open the toilet liquid valve and perform alveolar washing;

(27) Activate the negative pressure switch to collect toilet liquid/sputum suction.

It should be noted that, for the convenience of description, when describing the master terminal 1, the slave terminal 2 and the control terminal 4, the functions are divided into various units/modules and described separately. Of course, when implementing the present invention, the functions of each unit/module can be implemented in the same or multiple software and/or hardware. For example, at least part of the operating unit 1100, the control terminal 4, and the display unit 1300 may be integrated in the same hardware and embodied in a form similar to a tablet computer; or, the operating unit 1100, the control terminal 4 and the display unit 1300 are arranged independently of each other, the operation unit 1100 corresponds to a keyboard/mouse/control handle/touch interface, etc., the control terminal 4 corresponds to a host, and the display unit 1300 corresponds to a display. The specific presentation shape of the main terminal 1 does not constitute a limitation to the present invention. Moreover, the number of the displays is multiple, which are respectively used for displaying images in the cavity, displaying the control main terminal interface and the login window, and so on. The surgical robot system provided by the present invention replaces at least part of the work of medical staff by teleoperating the bronchoscope, which can significantly reduce the risk of medical staff being infected during the diagnosis and treatment of respiratory diseases.

The control terminal 4 and the patient terminal can also be separately located in different hospitals and different regions, and are connected by remote communication technology.

In the present invention, there is no particular limitation on the type and size of the bronchoscope 5. Please refer to FIG. 9, which shows a bronchoscope 5. In this embodiment, the bronchoscope 5 is a flexible bronchoscope, and includes a bronchoscope body 51, a catheter 52, an injection tube 53, a suction tube 54, a suction valve switch 55, and a catheter drive knob 56. The catheter 52 includes an observation channel for inserting into the patient's lungs, bronchus and other target tissues, so that the operator can observe the target tissue lesions through the lens in the observation channel. The catheter 52 may also include a functional channel communicating with the injection tube 53 for performing surgical operations such as perfusion and biopsy. For example, the operator injects liquid (such as saline or liquid medicine, etc.) into the distal end of the catheter 52 through the injection tube 53, and the liquid flows into the patient's lungs to achieve surgical operations such as bronchoalveolar lavage. In addition, the functional channel is also in communication with the suction tube 54 through which liquid can be sucked from the distal end of the catheter 52 to suck the fluid in the patient's body. The suction valve switch 55 can control the opening and closing of the suction tube 54 to realize the control of the suction of the liquid. Generally, the operator needs to press the suction valve switch 55 to turn on the suction. The catheter drive knob 56 is used to drive the distal end of the catheter 52 to swing, and the operator can adjust the swing direction of the distal end of the catheter 52 by rotating the catheter drive knob 56. In the use of the existing bronchoscope 5, the operator holds the bronchoscope body 51 and manipulates the bronchoscope 5 to be delivered forward and backward to the distal end, so that the catheter 52 is moved forward and backward in the axial direction, so that the distal end of the catheter 52 is at the target of the patient. Advance and retreat in the tissue; the operator can also manipulate the bronchoscope 5 to rotate circumferentially within the range of ±120° around the axis, so that the distal end of the catheter 52 can be rotated circumferentially within the target tissue of the patient to achieve the distal position of the catheter 52 Make adjustments; the operator manipulates the catheter drive knob 56 to swing the distal end of the catheter 52 within the target tissue of the patient. In this way, the posture adjustment of the distal end of the catheter 52 is realized.

Cooperating with the above-mentioned bronchoscope 5, please refer to FIG. 10. The lens holding arm 2 provided in this embodiment realizes the clamping of the bronchoscope 5 and the adjustment of the drive of the bronchoscope 5 to the desired posture. Preferably, the bronchoscope can also be realized 5. Injection and suction functions. In some embodiments, the lens holding arm 2 includes: a base 26, a lens holding base 27, and a clamping mechanism 10; The lens holder 27 is rotatably arranged on the base 26 around its own axis 20. The clamping mechanism 10 is used to clamp the bronchoscope 5. The clamping mechanism 10 moves axially on the lens holder 27 to drive the bronchoscope 5 to move forward and backward in the axial direction. The lens holder 27 rotates around its own axis 20 to drive the clamping mechanism 10 and the bronchoscope 5 to rotate around the axis. In practice, a person skilled in the art can, according to the prior art, provide a rotary joint on the base 26 to drive the lens holder 27 to rotate; and provide a movable joint on the lens holder 27 to move the clamping mechanism 10. The rotary joint and the moving joint can be driven in the form of a servo motor, a linear motor, a screw mechanism or an air cylinder, for example. The rotary joint and the mobile joint can be communicatively connected with the control terminal 4, and the operator can remotely control them. Further, the robot body 3 may also include more joints to provide a more flexible adjustment method, higher adjustment accuracy and larger working space for the mirror arm 2. For example, the robot body 3 may be provided with lifting joints or several rotations. Joints, etc., so that the mirror-holding arm 2 can be raised and lowered or can be rotated vertically around the robot body 3, etc. These lifting joints or rotating joints are also communicatively connected with the control terminal 1, and the movement is realized under the control of the control terminal 1. Furthermore, the robot body 3 is provided with casters, which is convenient for the operator to move the entire mirror-holding robot.

In some embodiments, the rotation angle of the lens holder 27 ranges between ±170°. The circumferential rotation (ie, rotation) angle of the existing bronchoscope 5 is often limited, and is generally within the range of ±120°. However, the rotation of the lens holder 27 can provide a larger range for the rotation angle of the bronchoscope 5 to increase the working space of the bronchoscope 5. Furthermore, since the rotation of the lens holder 27 is driven by a structure such as a servo motor, the accuracy of its rotation is relatively high.

Please refer to FIG. 11, in an exemplary embodiment, the clamping mechanism 10 includes: a clamping base 11, a knob driving mechanism 15, and a lens fixing mechanism 13. The knob driving mechanism 15 is used for coupling with the catheter driving knob 56 of the bronchoscope 5 to drive the distal end of the bronchoscope 5 to swing through the catheter driving knob 56. The holding seat 11 has an inner cavity 110, and the inner cavity 110 has a radial opening facing the bronchoscope 5. The inner cavity 110 is used for the bronchoscope body 51 to be inserted from the opening. The mirror body fixing mechanism 13 is switched between a first locked state and a first open state. When the mirror body fixing mechanism 13 is in the first locked state, the mirror body fixing mechanism 13 is connected to the clamping base 11, and together with the inner cavity 110, it defines the inner cavity 110 The bronchoscope body 51. When the scope fixing mechanism 13 is in the first open state, the restriction on the bronchoscope body 51 is released. Furthermore, the clamping mechanism 10 further includes a valve pressing mechanism 12. The valve pressing mechanism 12 includes a valve pressing block 121 (shown in FIG. 12), and the valve pressing mechanism 12 switches between a second locked state and a second open state. When the valve pressing mechanism 12 is in the second locked state, the valve pressing block 121 is used to direct the suction valve switch 55 of the bronchoscope 5 in the inner cavity 110 (shown in FIG. 9). ) Apply force to open the suction valve switch 55; when the valve pressing mechanism 12 is in the second open state, release the force applied to the suction valve switch 55.

In the above example, the patient end may also be provided with a suction device 8 (see FIG. 9 ), and the suction device 8 is in communication with the suction tube 54 and is communicatively connected with the control end 4. The operator can control the suction flow at the control end 4 by controlling the suction device, such as suction flow, flow rate and so on. The suction device 8 includes components such as a solenoid valve or a proportional valve, which can realize the opening and closing of the suction passage, and the flow control. Based on the above configuration, as shown in Fig. 12 in conjunction with Figs. 14, 15, the valve pressing mechanism 12 presses the suction valve switch 55 through the valve pressing block 121, which can keep the suction valve switch 55 in a normally open state, and achieve this by controlling the suction device The opening and closing of the suction path.

The inventor found that the duct 52 is generally a hose, and the duct 52 may bend during the axial movement of the clamping mechanism 10 with the lens holding arm 2. Furthermore, the clamping mechanism 10 further includes a catheter protection mechanism 14; the catheter protection mechanism 14 is detachably arranged at the distal end of the clamping base 11 for the catheter 52 of the bronchoscope 5 to pass through. The setting of the catheter protection mechanism 14 can limit the radial bending of the catheter 52 and avoid undesired bending of the catheter 52. The distal end of the catheter protection mechanism 14 may be close to the head of the patient, that is, close to the insertion end of the catheter 52.

Since the operation needs to be performed in a sterile environment, the bronchoscope 5 needs to be sterilized before the operation. In addition, patients of different body types, conditions and treatment methods require different models and types of bronchoscopes. In order to facilitate the replacement or installation of the bronchoscope 5, the inner cavity 110 is configured to have an opening facing the bronchoscope 5 in a radial direction. With this arrangement, the bronchoscope body 51 can be easily inserted into the inner cavity 110 of the holder 11, so that the bronchoscope body 51 can be restricted by the mirror body fixing mechanism 13 and the bronchoscope 5 can be restricted by the catheter protection mechanism 14 The duct 52 protects. As a result, a clamping of the entire bronchoscope 5 is formed, thereby replacing the operation mode of the operator holding the bronchoscope 5 and facilitating the replacement or installation of the bronchoscope 5. This further makes it possible to arrange the clamping mechanism 10 on the mirror holding arm 2 and the mirror holding robot to allow the operator to manipulate the bronchoscope 5 through remote control, thereby avoiding the operator from being exposed to high-risk areas and reducing the need for the operator Physical fatigue during the operation also reduces the risk of infection.

In some embodiments, referring to FIG. 12, FIG. 17, FIG. 18 and FIG. 23, the clamping seat 11 includes a first positioning member 111. The lens body fixing mechanism 13 includes a lens body pressing block 131 and a second positioning member 132. The second positioning member 132 is fixedly disposed on the lens body pressing block 131. When the mirror body fixing mechanism 13 is in the first locking state, the first positioning member 111 and the second positioning member 132 are configured to be mated and connected. At least part of the shape of the lens body pressing block 131 is adapted to the shape of the bronchoscope body 51. In some embodiments, the lens body pressing block 131 is movably disposed on the clamping base 11. For example, the lens body pressing block 131 is rotatably arranged on the clamping base 11 through a pin shaft; or the mirror body pressing block 131 is slidably arranged on the clamping base 11 through a sliding groove. In other embodiments, the lens body pressing block 132 is detachably disposed relative to the clamping base. When the lens body pressing block 131 is slid, rotated or installed to the expected position on the clamping base 11, the first positioning member 111 and the second positioning member 132 are correspondingly connected in cooperation to realize the fixing of the lens body pressing block 131. As a result, the lens body pressing block 131 and the inner cavity 110 jointly restrict the bronchoscope body 51. It should be noted that the restriction on the bronchoscope body 51 here includes restricting at least one of the movement of the bronchoscope body 51 in the axial, radial and circumferential directions, preferably restricting the bronchoscope body 51 in the axial, radial and circumferential directions. The movement in the direction so that the bronchoscope body 51 is reliably fixed in the inner cavity 110 of the holder 11. The lens body pressing block 132 covers at least a part of the opening of the inner cavity 110 to restrict the bronchoscope body 51 from coming out of the opening. Further, when the lens body pressing block 131 is movably arranged on the clamping base 11, the first positioning member 111 and the second positioning member 132 are disconnected from the mating connection, and the lens body pressing block 131 is rotated or slid to expose the inner cavity 110, so that the lens fixing mechanism 13 is in the first open state. When the lens body pressing block 131 is detachably arranged with respect to the clamping base 11, the first positioning member 111 and the second positioning member 132 are disconnected from the mating connection, and the lens body pressing block 131 is configured to be detached from the clamping seat. The seat 11 exposes the opening of the inner cavity 110, so that the lens fixing mechanism 13 is in the first open state.

The first positioning member 111 and the second positioning member 132 include magnetic members that engage with each other; or, the first positioning member 111 and the second positioning member 132 include engaging members that engage with each other. In order to quickly and conveniently open the lens body pressing block 131 and realize the rapid replacement of the bronchoscope 5, the first positioning member 111 and the second positioning member 132 should be configured as a mechanism that can be quickly connected and disconnected. In some embodiments, as shown in FIGS. 17 and 18, the first positioning member 111 and the second positioning member 132 include magnetic members that are attracted to each other. It should be understood that the magnets attracted to each other here are not limited to the first positioning member 111 and the second positioning member 132 including magnets at the same time. One of them may include a magnet and the other may include a ferromagnetic body, such as the first positioning member. 111 includes a permanent magnet, and the second positioning member 132 includes an iron block, as long as the two can be attracted to each other. When the first positioning member 111 and the second positioning member 132 include magnets at the same time, the opposing surfaces of the two magnets should be configured as different poles. In some other embodiments, the first positioning member 111 and the second positioning member 132 include buckling members that are engaged with each other, and the two can be engaged and connected by pressing relative to each other and separated from each other by pulling apart. Of course, those skilled in the art can also perform different configurations for the quick connection between the first positioning member 111 and the second positioning member 132 according to the prior art, and the present invention is not limited thereto. It should be understood that, in some embodiments, the lens body pressing block 131 may be integrally formed with the second positioning member 132, and even the whole lens body pressing block 131 is made of ferromagnetic material. It is understandable that for various bronchoscopes 5 of different models, a plurality of lens body pressing blocks 131 of different shapes can be equipped to improve the adaptability of the mirror-holding robot.

In some embodiments, please refer to FIG. 23, the lens body fixing mechanism 13 further includes a lens body spacer 133. The lens block 133 is detachably disposed on the clamping base 11. When the lens body fixing mechanism 13 is configured to be in the first locked state, the lens body pad 133 is located between the lens body pressing block 131 and the holding seat 11, and is connected to the first positioning The member 111 and at least one of the second positioning member 132 are matedly connected. Preferably, at least part of the shape of the lens body spacer 133 is adapted to the outer contour of the bronchoscope body 51. In actual use, the lens body spacer 133 directly abuts and contacts the bronchoscope body 51 to achieve a limit on the bronchoscope body 51. It is understandable that for various types of bronchoscopes 5, a plurality of mirror body blocks 133 of different shapes can be equipped to improve the adaptability of the mirror-holding robot. The side of the lens body pressing block 131 and the lens body pad 133 for abutting contact with the bronchoscope body 51 may be provided with a flexible material such as silicone to form a soft cushion to avoid scratches and damage to the bronchoscope body 51. Of course, the lens body pressing block 131 and the lens body spacer 133 can also be made of polymer materials to make them relatively soft, so as not to scratch or damage the bronchoscope body 51.

In some embodiments, a magnet or a magnet, such as a ferromagnetic piece, may be provided on the mirror body spacer 133 at positions corresponding to the first positioning member 111 and the second positioning member 132. In this way, the mirror body block 133 can be conveniently positioned to a proper position. In some other embodiments, fixing holes may be opened on the mirror block 133 corresponding to the first positioning member 111 and the second positioning member 132. The size of the fixing hole is adapted to the size of the first positioning member 111 so that it can be sleeved and snapped on the first positioning member 111, so that when the second positioning member 132 is mated and connected with the first positioning member 111, the At the same time, the position of the mirror block 133 is fixed.

Please refer to FIG. 11, FIG. 12, FIG. 13, FIG. 21 and FIG. 22, the knob driving mechanism 15 includes a transmission component 152. The transmission component is rotatably arranged on the clamping base 11 and is used to drive the catheter driving knob 56 of the bronchoscope 5 to rotate. Correspondingly, the patient end also includes a knob driving component, which is communicatively connected with the control terminal 4 and used to drive the transmission component 152 in the knob driving mechanism 15 to rotate, thereby realizing the swing of the end of the bronchoscope 5. In an example, the transmission component 152 includes a cam 153 located in the inner cavity 110 and a transmission shaft 154 passing through the clamping base 11. The driving component is arranged outside the clamping base 11 and is coupled to the transmission shaft 154. The cam 153 is eccentrically arranged with respect to the transmission shaft 154 and is coupled to the catheter drive knob 56 of the bronchoscope 5 for driving the catheter drive of the bronchoscope 5 under the rotation of the transmission shaft 154 The knob 56 is turned. Since the cam 153 is eccentrically arranged with respect to the transmission shaft 154, the transmission shaft 154 rotates and drives the cam 153 to rotate under the drive of the driving component, and the coupling of the cam 153 and the catheter drive knob 56 swings around the axis of rotation of the transmission shaft 154 (Refer to Figures 21 and 22).

Please refer to FIGS. 21 and 22, the cam 153 is connected to the catheter drive knob 56 through a torque transmission mechanism 62. The torque transmission mechanism 62 includes a cam sleeve 621 located on the outer side and a limiting body 622 located on the inner side. The cam sleeve 621 is used to be sleeved on the cam 153 so that the torque transmission mechanism 62 rotates with the cam 153. The limiting body 622 is used for connecting with the catheter driving knob 56 and driving the catheter driving knob 56 to rotate. After the cam sleeve 621 is sleeved on the cam 153, at least the circumferential direction remains relatively stationary with the cam 153. The restricting body 622 is matched with the catheter driving knob 56 so that when the cam sleeve 621 rotates with the cam 153, the restricting body 622 then drives the catheter driving knob 56 to rotate, so that the catheter driving knob 56 is driven to rotate by the knob driving component. Further, the cam 153 includes two opposite sides, and the two sides are parallel. The cam sleeve 621 includes a slot for receiving the cam 153 and the size of the slot is adapted to the distance between the two sides of the cam 153. Further, the cam sleeve 621 has an open end along the extending direction of the slot, and the cam sleeve 621 is sleeved on the cam 153 from the open end. With this configuration, the cam sleeve 621 can be conveniently sleeved and installed on the cam 153 along the opening direction of the inner cavity 110.

In some other embodiments, the transmission component 152 is not limited to the combination of the cam 153 and the transmission shaft 154. For example, it can also be driven by a magnetic coupling, which can also easily transfer the torque from the clamping base 11 Transfer to the inner cavity 110.

In some embodiments, please refer to FIG. 12, FIG. 14 and FIG. 15, the valve pressing block 121 is rotatably disposed on the clamping seat 11. The valve pressure block 121 can rotate between an open position and a closed position. As shown in Figs. 12 and 14, the valve pressure block 121 is in the open position, and the suction valve switch 55 is not subjected to external force and remains closed. As shown in FIG. 15, the valve pressing block 121 is in the closed position, exerting force on the suction valve switch 55 to keep the suction valve switch 55 in the open state. Furthermore, when the valve pressing block 121 is in the open position, the bronchoscope body 51 can be freely taken out and put in from the opening of the inner cavity 110 more conveniently. When the valve pressure block 121 is in the closed position, the valve pressure block 121 can not only apply force to the suction valve switch 55, but also restrict the bronchoscope body 51 located in the inner cavity 110 to further ensure that the bronchoscope The fixed effect of the body 51. Preferably, the rotation axis of the valve pressing block 121 is perpendicular to the axial direction of the bronchoscope 5. Of course, in some other embodiments, the valve pressure block 121 is not limited to be rotatably disposed on the clamping seat 11, and the valve pressure block 121 may also be slidably disposed on the clamping seat 11, even relative to The clamping base 11 is detachably arranged. For example, a sliding groove may be provided on the clamping seat 11, and the valve pressing block 121 slides on the sliding groove. When the valve pressure block 121 slides to the desired position, it can overlap with the suction valve switch 55 and apply force to the suction valve switch 55; and when the valve pressure block 121 slides in the opposite direction, the suction valve switch 55 can be exposed. Releasing the force applied to the suction valve switch 55 can also expose the opening of the inner cavity 110 further. Those skilled in the art can appropriately configure the connection between the valve pressure block 121 and the clamping seat 11 based on the above-mentioned ideas and actual conditions.

Further, the valve pressing mechanism 12 includes a locking buckle 122 arranged on the clamping seat 11. The locking buckle 122 is configured to lock the rotation of the valve pressing block 121 so that the valve pressing mechanism 12 is in the second locked state. The locking buckle 122 is configured to unlock the rotation of the valve pressing block 121 so that the valve pressing mechanism 12 is in the second open state. When the valve pressure block 121 is in the closed position, the locking buckle 122 can lock the valve pressure block 121 to maintain the force of the valve pressure block 121 on the suction valve switch 55. For example, the locking buckle 122 can be configured to be locked and unlocked by pressing. Those skilled in the art can appropriately set the locking buckle 122 according to the prior art, which will not be repeated here.

Please refer to FIG. 11 and FIG. 16, the catheter protection mechanism 14 includes a telescopic sheath 141 and a connecting portion 142. The connecting portion 142 is used for detachably connecting with the clamping base 11. The telescopic sheath 141 is fixedly connected to the connecting portion 142 and is arranged telescopically along the axial direction. The connecting portion 142 has a first through hole for penetrating the catheter 52 of the bronchoscope 5, and the telescopic sheath 141 has a second through hole for penetrating the catheter 52 of the bronchoscope 5 , The first through hole and the second through hole are arranged coaxially. In use, the holder 11 needs to move axially along the lens holder 27, but the robot body 3 generally does not move so that the distance between the robot body 3 and the patient does not change and the distal end of the catheter protection mechanism 14 should be close The patient should also remain unchanged or keep a distance away from the patient. Therefore, the catheter protection mechanism 14 needs to be configured to be retractable, so that when the clamping base 11 moves in the axial direction, the distal end position of the catheter protection mechanism 14 remains unchanged or controlled. For ease of use, the connecting portion 142 is detachable relative to the clamping base 11 so that the catheter protection mechanism 14 can be sleeved outside the catheter 52.

Please refer to FIG. 25, FIG. 26 and FIG. 27. In an exemplary embodiment, the connecting portion 142 is detachably connected with the clamping base 11 through an insert 63. The inner cavity 110 has a limit surface 112, and the limit surface 112 is used to limit the circumferential rotation and movement of an insert 63 toward the distal end. The insert 63 includes a stepped surface 631, and the stepped surface 631 is used to abut against the limiting surface 112 of the clamping seat 11 to restrict the insert 63 from rotating circumferentially and moving toward the distal end. In some embodiments, the distal end of the insert 63 has a fixing portion 632 for detachably connecting with the connecting portion 142 of the catheter protection mechanism 14. The connecting portion 142 has an internal thread, and the fixing portion 632 has an external thread matching the connecting portion 142. The fixing portion 632 is used to drive the insert 63 to move distally under the rotation of the connecting portion 142, so that the step surface 631 abuts the limit surface 112, and the connecting portion 142 The proximal surface of the clamp abuts against the distal surface of the clamping seat 11. Of course, in some other embodiments, it is also possible that the connecting portion 142 has an external thread, and the fixing portion 632 has an internal thread. With the above configuration, the catheter protection mechanism 14 can be fixedly connected to the clamping base 11 by tightening the catheter protection mechanism 14. The insert 63 has a third through hole that penetrates, and the third through hole is used for the catheter 52 of the bronchoscope 5 to pass through. In some embodiments, after the insert 63 is installed in the clamping base 11, the third through hole remains coaxial with the first through hole and the second through hole. Of course, the connection manner of the catheter protection mechanism 14 and the clamping base 11 is not limited to the above manner. In some other embodiments, the catheter protection mechanism 14 can also be connected to the clamping base 11 by means of snaps, etc., and those skilled in the art can make changes according to actual conditions.

In some embodiments, as shown in FIG. 11, the telescopic sheath 141 includes a plurality of telescopic sections 143, and the plurality of telescopic sections 143 are coaxially sleeved and connected in sequence. The telescopic sheath 141 expands and contracts by the mutual movement of the plurality of telescopic joints 143 in the axial direction. As shown in FIGS. 29 and 30, in an exemplary embodiment, the telescopic sheath 141 includes a plurality of telescopic sections 143, so that the telescopic sheath 141 can be telescopic in the axial direction like a fishing rod. In some other embodiments, the telescopic sheath 141 can also adopt other structures, such as a bellows structure, a number of collars arranged at intervals, etc. Those skilled in the art can choose a suitable structure according to the prior art. Unlimited.

Please refer to FIGS. 10 and 30, the lens holding arm 2 further includes a catheter holder 28, and the catheter holder 28 is disposed at the distal end of the lens holder 27. Preferably, the catheter support 28 and the lens holder 27 are detachably connected. Such a configuration can facilitate the installation of the bronchoscope 5 and the catheter protection mechanism 14. The catheter support 28 is used to connect with the catheter protection mechanism 14 and restrain the catheter protection mechanism 14 at least in the telescopic direction of the catheter protection mechanism 14. The arrangement of the catheter support 28 can provide additional support for the distal end of the catheter protection mechanism 14 and improve the stability of the catheter protection mechanism 14. In an exemplary embodiment, the catheter holder 28 has a fourth through hole. The inner diameter of the fourth through hole is matched with the outer diameter of the telescopic sheath 141 of the catheter protection mechanism 14, allowing the catheter support 28 to be sleeved with the catheter protection mechanism 14. Preferably, the fourth through hole and the third through hole are arranged coaxially. In some other embodiments, the catheter support 28 may also be in the form of an open bracket, which only needs to provide a supporting force for the distal portion of the catheter protection mechanism 14. Therefore, it can be understood that the catheter support 28 restricts the radial swing of the catheter protection mechanism 14 so that it can have radial freedom in only one direction, such as restricting the radial freedom of the catheter protection mechanism 14 in the direction of gravity, without restricting Upward radial degrees of freedom. Further, the open bracket can also be configured to have magnetism, and correspondingly, the distal portion of the catheter protection mechanism 14 is an adapted magnetic or ferromagnetic piece, for example, the telescopic sheath 141 is an iron pipe. In this way, the open bracket can also provide attractive force to the distal portion of the catheter protection mechanism 14 to fix the distal portion of the catheter protection mechanism 14.

In some embodiments, the catheter support 28 and the catheter protection mechanism 14 are detachably connected, that is, the catheter protection mechanism 14 can be set separately from the catheter support 28. After the catheter 52 is inserted into the catheter protection mechanism 14, the catheter protection mechanism 14 and the catheter support 28 are assembled and connected. In some embodiments, the catheter support 28 is movably arranged on the catheter protection mechanism 14, such as slidably or rotatably arranged on the catheter protection mechanism 14. In some other embodiments, the catheter support 28 may also be detachably fixed on the catheter protection mechanism 14 or even be integrally formed with the catheter protection mechanism 14.

As mentioned above, the operation process needs to be performed in a sterile environment, so the bronchoscope 5 needs to be replaced and sterilized before the operation. However, components such as the holder 11, the lens holder 27, and the base 26 are difficult to sterilize by common sterilization methods because they are provided with electronic components. Therefore, it is necessary to use a sterile isolation mechanism to wrap these components during surgery, so that these components are physically separated from the sterile area. After one use, the aseptic isolation mechanism can be replaced.

Based on this, an embodiment of the present invention also provides a sterile isolation mechanism 60. Please refer to Figure 19, which shows an exemplary setting range of the aseptic isolation mechanism 60, which at least wraps the holder 11, the lens holder 27 and the base 26, and at least the The catheter protection mechanism 14 is exposed. The aseptic isolation mechanism 60 also wraps components such as the valve pressing mechanism 12 and the rotation driving component. In some embodiments, the aseptic isolation mechanism 60 may also wrap a part of the robot body 3 or the entire robot body 3. In this way, the exposed catheter protection mechanism 14 and the covered inner cavity 110 can be conveniently used for replacement and installation of the bronchoscope 5. Therefore, after the sterile isolation mechanism 60 is replaced after one use, the robot can be quickly used for the next use, which improves the use efficiency of the entire mirror-holding robot.

The aseptic isolation mechanism 60 provided in this embodiment will be schematically described below with reference to an exemplary example.

Please refer to FIG. 20, the aseptic isolation mechanism 60 includes an isolation bag 61 and a torque transmission mechanism 62.
