Example 1

As an endoscope detection method provided by an embodiment of the present invention, the detection method uses an endoscope detection system, referring to fig. 3, the endoscope detection system includes an endoscope 1, a host 4, and a connection cable 3, the connection cable 3 connects the endoscope 1 and the host 4, and the connection cable 3 transmits signals therebetween. The signal transmission direction may include a control signal transmitted from the host computer 4 to the endoscope 1, and also include an image signal transmitted from the endoscope 1 to the host computer 4, an operation state feedback signal of the endoscope 1, and the like.

First, a structural example of the endoscope 1 will be described. The endoscope 1 of the present embodiment may be a disposable endoscope 1 or may be an endoscope 1 in which the insertion portion 11 is used a limited number of times. Wherein, the disposable endoscope 1 is disposed of from the polluted part after use, so that the sanitation degree of the endoscope 1 can be improved, and the safe use of a subject can be ensured. Both the handle 12 and the insertion portion 11 are contaminated during use, and therefore both the handle 12 and the insertion portion 11 need to be discarded to ensure safe use of the endoscope 1. The endoscope 1 in which the insertion portion 11 is used a limited number of times can be used several times for the insertion portion 11, and can be used next time after each use is sterilized, but the total number of uses is limited.

The handle 12 of the endoscope 1 is shaped to facilitate the hand holding of the operator and to facilitate the forced operation. The insertion portion 11 includes an insertion tube and a bending portion 13, and the tip of the insertion tube is provided with the bending portion 13. From one side of the handle 12, a pull wire (not shown) extends through the insertion tube and the bend 13. The bending portion 13 is provided with a plurality of snake bone structures rotatably connected to each other. The snake bone structure can rotate freely. The inside wall of the snake bone structure is provided with a guide groove, and the traction wire passes through the guide groove to be in traction connection with the snake bone structure. When the handle 12 pulls the traction wire, the snake bone structure is driven to rotate or bend, so that the bending direction and the bending angle of the bending part 13 connected with the other end of the traction wire can be controlled. The bending part 13 is bent and stretched into the cavity to guide the insertion tube to move in the cavity. The handle 12 is provided with a control knob. The control knob is connected with the traction wire, and the traction wire is pulled and moved by rotating the control knob. The control knob can be a plurality of hand wheels which are coaxially arranged up and down. The finger of the operator can be moved.

The pipe of the insertion portion 11 corresponds to a gas-liquid transmission pipe, an image transmission line for transmitting an image signal, a power supply line for supplying power, and other signal lines for controlling and detecting. An image acquisition module and an illumination optical module are provided at the front end of the curved portion 13. The image acquisition module may include a CCD, CMOS, or other imaging device. The image acquisition module is used for acquiring image information in the cavity of the detected person and transmitting the image signal to the host computer 4 through the image transmission line so that medical staff can diagnose and treat the detected person according to the image information. The bending portion 13 is further provided with an observation window, an air supply nozzle, and a water supply nozzle. The gas and liquid delivered by the gas-liquid delivery pipeline are correspondingly sprayed out from the gas delivery nozzle and the water delivery nozzle so as to clean the surface of the observation window. The handle 12 is also provided with a control button which is electrically connected with the pump set of the endoscope 1. The pump set of the endoscope 1 is used for pumping gas or liquid or the like into the gas-liquid conveying pipeline for the use of the endoscope 1 during the use process. The control button can control the working state of the pump group. The operating state of the pump unit may include switching of the pump unit, adjustment of parameters, etc.

Referring to fig. 1, the endoscope detection method includes the steps of:

s51, connecting the host 4 and the endoscope 1, and acquiring the historical plug times between the endoscope 1 and the connecting cable 3;

s52, judging whether the historical plugging times are larger than the reference times, if not, the host computer 4 is in signal connection with the endoscope 1, and the plugging operation between the endoscope 1 and the host computer 4 is monitored, wherein the plugging operation comprises plugging operation and pulling-out operation;

s53, when the endoscope 1 and the host 4 complete one-time plug operation, based on the historical plug times, recording that the plug times of the endoscope 1 are increased once;

s54, when the total plugging times are larger than the first preset times, the signal connection between the endoscope 1 and the host computer 4 is cut off or alarm information is sent.

In step S51, the host computer 4 and the endoscope 1 are electrically connected. One end of the connecting cable 3 is provided with a first communication interface 31 for plugging with a handle interface on the handle 12 of the endoscope 1 to realize electric connection. The other end of the connection cable 3 has a second communication interface for electrical connection with the host 4. When the two ends of the connecting cable 3 are respectively and electrically connected with the handle interface of the endoscope 1 and the host 4, the host 4 is electrically communicated with the endoscope 1.

In general, when the host computer 4 and the endoscope 1 are electrically connected, the number of insertions recorded by the number of insertions recording module is counted from 0. But in order to prevent the endoscope 1 from having been used before, in some embodiments, secondary use is prevented by taking a historical number of insertions between the endoscope 1 and the connection cable 3 to determine whether the endoscope 1 has been used.

The reference number is generated by the unavoidable insertion and extraction operation of the endoscope 1 before the endoscope is not used for the operation, because of the production or test requirements. The reference number of times may be set to 0, or any number greater than 0. Therefore, if the number of times of historical insertion and extraction between the endoscope 1 and the connection cable 3 is acquired to be equal to or less than the reference number of times, this indicates that the endoscope 1 is not used, and there is no risk of secondary use, and thus can be used for the current operation.

In another embodiment, after the step of obtaining the historical number of insertions and removals between the endoscope 1 and the connection cable 3 after the host computer 4 and the endoscope 1 are in electrical communication, the method further comprises:

if the historical plugging times of the endoscope 1 are larger than the reference times, the communication connection between the endoscope 1 and the host computer 4 is cut off, or alarm information is sent out;

In this embodiment, if the number of times of historical insertion and extraction is greater than the reference number, this indicates that the endoscope 1 has been used before, and this use has a risk of secondary use, so that an alarm message may be displayed by the display module 32, or an operator may be alerted by other alarm means. Here, the controller in the connection cable 3 may issue an interrupt communication command to the host computer 4 to stop the host computer 4 from receiving the signal transmitted from the endoscope 1, so that the endoscope 1 is strictly prevented from being used. The host computer 4 may acquire the recording result of the plug number recording module, and stop receiving the signal sent by the endoscope 1, or send an alarm. The present embodiment thus improves the safety of use of the endoscope 1.

In this embodiment, the history of the number of insertions and removals between the endoscope 1 and the connection cable 3 is acquired to determine whether the endoscope 1 has been used before, so that the use of the endoscope having a secondary use risk is avoided. Further, when the number of times of historical insertion and extraction of the endoscope 1 in this embodiment is smaller than or equal to the reference number of times, communication between the host computer 4 and the endoscope 1 is communicated, the endoscope 1 enters a use state, insertion and extraction operations between the endoscope 1 and the host computer 4 are monitored in the use process, when the endoscope 1 and the host computer 4 complete one insertion and extraction operation, the number of times of insertion and extraction of the endoscope 1 is recorded once based on the number of times of historical insertion and extraction, when the number of times of insertion and extraction is larger than the first preset number of times, it is indicated that the endoscope 1 has a risk of secondary use or is already being used for the second time, so that the endoscope 1 is prevented from being used continuously by cutting off the communication connection between the endoscope 1 and the host computer 4 or sending out alarm information. Therefore, the present embodiment achieves the purpose of preventing secondary use, and improves the use safety of the endoscope 1.

Further, considering that the flow and the number of times of the usage status test of different manufacturers are different, in an embodiment of the present application, the method further includes:

when the host 4 and the endoscope 1 are electrically connected, the type of the connected host 4 is acquired;

if the type of the host 4 is detected as the test host 4, the plug operation is not counted.

Based on the embodiment, the count of the plug operation is not affected by the plug operation in the test process, so the reference number of times may be set to 0. According to the scheme, the influence of the plugging operation on the recorded plugging times in the testing process is effectively avoided, and the accuracy of the plugging times recording is improved, so that the accuracy of judging whether the endoscope 1 is used secondarily is improved.

Further, the step of obtaining the historical number of plugging/unplugging times of the endoscope 1 and the connecting cable 3 includes:

after the host computer 4 and the endoscope 1 are electrically communicated, the identity information of the endoscope 1 is acquired;

searching the identity information of the endoscope 1 in an identity information base of the endoscope 1, wherein the identity information base is used for recording the identity information of the endoscope 1 which has a connection relation with the connecting cable 3 and the historical inserting and extracting times of the endoscope 1 corresponding to the identity information;

If the identity information of the endoscope 1 is found, the history plug times of the endoscope 1 corresponding to the identity information are called; if the identity information of the endoscope 1 is not found, the identity information is built for the endoscope 1 in the identity information library, and the historical plugging frequency is set to 0.

Specifically, the identity information may be embodied by a serial number, a bar code, a two-dimensional code identified on the endoscope 1. After the first communication interface 31 is electrically connected with the handle interface, the controller in the connection cable 3 may communicate with the main control circuit in the endoscope 1, so as to obtain the identity information of the endoscope 1. The identity information base of the endoscope 1 may be stored in a server or in a network cloud. The controller can access the identity information library directly or through the host 4 and search the identity information of the endoscope 1 and the corresponding previously recorded used times, thereby knowing the history of insertion and removal of the endoscope 1 for medical staff to determine whether the endoscope 1 has been used. The present embodiment further improves the standardization of the use management of the endoscope 1, and can effectively prevent the endoscope 1 from being used secondarily.

The history identity information of the endoscope 1 may be acquired by the connection cable 3 or by the host computer 4.

In another option of obtaining the historical number of insertions, a memory may be provided within the endoscope 1 for storing the number of insertions between the endoscope 1 and the connection cable 3. When the connection cable 3 is connected to the endoscope 1, the history of the number of insertion and removal can be obtained by reading the data in the memory.

In step S52, if the number of times of historical insertion and removal of the endoscope 1 is less than or equal to the first preset number of times, it indicates that the endoscope 1 has no risk of secondary use and can be used. Here, monitoring the insertion and extraction operation between the endoscope 1 and the main body 4 may be achieved by monitoring the electrical connection state between the first communication interface 31 and the endoscope 1.

In step S53, when the endoscope 1 and the host 4 complete one insertion operation, the number of times of insertion and removal of the endoscope 1 is increased once based on the history of the number of times of insertion and removal. The insertion and removal operation includes two operations, one is the insertion operation of the endoscope 1 and the main body 4, and the other is the removal operation of the endoscope 1 and the main body 4. The two actions are not necessarily implemented at the same time, but can be counted only when one plugging operation is satisfied, but the next unplugging operation is not counted.

The number of plugging times may be recorded by a plugging times recording module in the connection cable 3, or may be recorded by the host 4.

In some cases, the medical staff may perform several insertion and extraction tests on the connection cable 3 and the endoscope 1 before surgery to detect whether the connection cable 3 and the endoscope 1 work well.

Thus, in order to make the recorded number of plugging operations truly reflect the number of uses of the endoscope 1, further, the step of monitoring the plugging operation between the endoscope 1 and the host 4 includes:

if the fact that more than or equal to two plugging operations exist between the endoscope 1 and the host 4 is monitored, the interval duration of two adjacent plugging operations is obtained;

if the interval duration is less than or equal to the first preset duration, judging that the first plug operation in the two adjacent plug operations is abnormal plug operation, and not counting the number of plug operations.

Specifically, the "obtaining the interval duration of the two adjacent plugging operations" includes obtaining the interval duration between the two corresponding plugging operations in the two adjacent plugging operations. The first preset time length can be set according to the test time length and can be set to 0.5-20 seconds, when the adjacent two-time plug operation is within the first preset time length, the controller judges that the plug operation is a false plug operation or a test plug operation, and at the moment, the plug frequency recording module does not count the first plug operation in the adjacent two-time plug operation. According to the scheme, interference caused by the plugging operation counting caused by the plugging operation or the test plugging operation can be effectively discharged, so that the plugging times can more truly reflect the use times of the endoscope 1, and the accuracy of judging the secondary use of the endoscope 1 is improved.

Further, an ambient light sensor is provided on the bending portion 13 of the endoscope 1;

if the ambient light sensor detects that the red light proportion is greater than or equal to a preset threshold value, judging that the bending part 13 enters a human body, and counting the two adjacent plugging operations as one plugging operation;

if the ambient light sensor detects that the proportion of red light is smaller than the preset threshold value, the endoscope 1 is judged not to enter the human body, and therefore the two plugging operations are not counted.

In the present embodiment, the ambient light sensor is provided at the distal end of the bending portion 13 of the endoscope 1, and can detect the ambient light component. The controller periodically acquires data acquired by the ambient light sensor, and marks the corresponding relation between the data and the acquisition time.

When the endoscope 1 enters the human body, the red light is more because the component proportion of the light in the human body and the ambient light is different, so that whether the endoscope 1 enters the human body can be judged to a certain extent by detecting the proportion of the red light. The preset threshold is a range or a lowest value of the proportion of red light in environments of different parts of the environment in the human body. Illustratively, the preset threshold may be set to 50%.

In this embodiment, when the interval time of two adjacent plugging operations is longer than the first preset time length, the two adjacent plugging operations are simultaneously judged by combining with the ambient light sensor, so as to comprehensively determine the counting problem of the two adjacent plugging operations, and avoid the situation that the endoscope 1 cannot be used due to the fact that the interval time of the two plugging operations is too long for objective reasons. The embodiment improves the flexibility and accuracy of recording the plugging times.

In step S54, when the number of plugging times is greater than the first preset number of times, the signal transmission between the control host 4 and the endoscope 1 is stopped, or an alarm message is sent.

The first preset times are larger than the reference times, the difference value of the first preset times and the reference times can be 1, and the difference value of the first preset times and the reference times is more than 1 according to different preoperative procedures. The specific value of the first preset number of times may be specifically set according to a manufacturer or a hospital.

Here, the communication connection between the endoscope 1 and the host computer 4 may be cut off by the controller in the connection cable 3, or the controller may send an interrupt communication command to the host computer 4, and the host computer 4 stops receiving the signal sent by the endoscope 1, so that the endoscope 1 is forced to be out of use.

In step S54, it is also possible to synchronize the marking that the endoscope 1 has been used, thereby avoiding that the endoscope 1 is used secondarily. The identification information can be marked in the identity information base of the endoscope 1.

Further, the connection cable 3 is further provided with a display module 32, and the method further includes:

when the host 4 and the endoscope 1 are electrically connected, the display module 32 obtains the latest number of times of insertion and extraction between the endoscope 1 and the host 4, and displays the latest number of times.

In this embodiment, when the connection cable 3 is electrically connected between the host 4 and the endoscope 1, the display module 32 instantly displays the current historical number of times of insertion and extraction of the endoscope 1, so that the operator quickly learns the historical use condition of the endoscope 1, and the secondary use of the endoscope 1 is effectively avoided. In addition, when a new plugging operation is performed during the process of electrically connecting the connection cable 3 to the host computer 4 and the endoscope 1, the display device displays synchronously in real time. Here, the display displays a cumulative number of plug operations that can be counted. In addition, the display content of the display screen 322 may also include various kinds of operation parameter information of the endoscope 1.

In this embodiment, by the design of the display module 32 on the connection cable 3, the working state information of the endoscope 1 does not need to be displayed on the screen of the host computer 4, or is displayed in a smaller occupied area, so that the screen of the host computer 4 can further enlarge the image, and the user can operate the operation more accurately.

In some embodiments, if the number of historical plugs of the endoscope 1 is less than or equal to the first preset number, the communication between the host 4 and the endoscope 1 is communicated, and the method further includes:

after communication between the communication host 4 and the endoscope 1, the display module 32 displays the electric communication duration between the host 4 and the endoscope 1;

generating first alarm information on the display module 32 when the electrical connection time period reaches a preset normal use time period; wherein the normal use time is less than the limit use time.

Here, the limit use period and the regular use period may be set individually by a manufacturer or a hospital according to the type of the endoscope 1. The normal use time length can be set to 70% -95% of the limit use time length. When the electrical communication duration recording module reaches the normal use duration, the display module 32 generates a first alarm message to alert the operator that there is little remaining use duration of the endoscope 1. The first alarm information may be expressed by changing or flashing the backlight color of the display module 32, or may be expressed by displaying warning characters or graphics on the display module 32.

Further, the method comprises the steps of:

generating a second alarm message on the display module 32 when the length of the electrical communication has reached the limit use length;

Starting a countdown on the display 322 and counting a second time period;

when the countdown is completed, the communication connection between the endoscope 1 and the host computer 4 is cut off.

The second alarm information is higher in warning than the first alarm information, and the operator is warned of the exhaustion of the residual using time of the endoscope 1 in a more warning manner. In addition to using a similar representation as the first alarm information, the second alarm information is also expressed in a speech manner, which may be based on a speaker assembly.

In order to secure the safety of the operation, the second time period may be set to a time period required to withdraw the endoscope 1 from the human body. Thus, the endoscope 1 can be ensured to safely and smoothly exit the human body, and the phenomenon that the endoscope 1 scratches the inner cavity of the human body in the process of exiting the human body due to the fact that the endoscope 1 stops working is avoided.

In this embodiment, by recording the electrical connection time length of the endoscope 1, the used time length of the endoscope 1 is determined, and when the electrical connection time length reaches the preset limit use time length, the communication connection between the endoscope 1 and the host 4 is cut off, so as to prevent the endoscope 1 from being used continuously, thereby achieving the purpose of preventing secondary use, and therefore, the application scheme improves the use safety of the endoscope 1.

And can further mark that the endoscope 1 has been used while the electrically connected time period reaches a preset limit use time period, so that when the endoscope 1 is reused after being disconnected from the host computer 4, the connection cable 3 or the host computer 4 can recognize the mark, thereby cutting off the communication between the endoscope 1 and the host computer 4, and achieving the purpose of preventing secondary use.

Further, if a special condition is encountered during the operation, the operation time needs to be prolonged, so in order to ensure the smooth operation, in an embodiment, when the electrical connection time length reaches the limit of the use time length, the step of generating the second alarm information on the display module 32 further includes:

before the preset limit use time is not reached, if a delay common instruction is received, the limit use time is prolonged according to the delay common instruction;

when the electrical communication time period reaches the new limit use time period, the communication connection between the endoscope 1 and the host computer 4 is cut off.

Here, the endoscope 1 may receive a time delay general command, and the controller may learn the time extension information through signal interaction with the endoscope 1, so as to control the display screen 322 to update the display limit use time period or the remaining use time period available for use. The time extension instruction may also be received by the host 4, and the time extension information may be transmitted to the controller through signal interaction.

Here, the operator has the authority to issue a time-lapse normal instruction, which is normally only once, so as to ensure that the use time of the endoscope 1 is strictly controlled and secondary use is prevented.

Specifically, the operator can directly send out the instruction by the man-machine interaction component on the host computer 4, or unlock the delay claim after inputting a specific password, or a slot for inserting an IC card is provided on the host computer 4, the endoscope 1 or the casing 321 of the display module 32, and the operator unlocks the delay claim by inserting the IC card, and further sends out a delay general instruction. The delay common instruction comprises a specific time length which needs to be prolonged.

For example, the preset limit use duration of the endoscope 1 is 120 minutes, when the record duration of the electric communication duration record module reaches 100 minutes, the operator sends out a delay common instruction, and the display updates and displays the limit use duration of 150 minutes or displays the residual use duration of 50 minutes after 30 minutes delay.

Further, if the operation is too complicated and still cannot be completed after the limit use time is prolonged, in order to ensure that the endoscope 1 can continue to support normal operation, in an embodiment, before the preset limit use time is not reached, if the delay normal instruction is received, after the step of prolonging the limit time according to the delay normal instruction, the method further includes:

Before the new limit use time is not reached, if a delay special instruction is received, the current limit use time is prolonged again according to the delay special instruction; wherein the delay special instruction is issued by the authorization key.

It should be noted that, herein, the "current limit use duration" is the limit use duration after the delay of the normal instruction.

The form of the authorization key may be varied, for example, an authorization shield provided by the manufacturer, which is typically administered by a higher level operator. After the above-mentioned normal delay claims have been used, the operator can also utilize the authorization key to extend the duration of the limit use one or more times, if necessary, to meet the surgical requirements.

According to the embodiment of the application, the normal delay instruction and the special delay instruction are used for adjusting the limit use time of the endoscope 1, so that the endoscope 1 can support smooth completion of an operation, and meanwhile, the limit use time of the endoscope 1 is prolonged excessively due to misoperation or maliciousness and is used for the next operation by setting the issuing authority of the normal delay instruction and the special delay instruction, so that the possibility that the endoscope 1 is used secondarily is effectively reduced.

In connection with the above embodiments, if the limit use period is excessively prolonged, the endoscope 1 has a remaining use period after the operation is ended, so in order to prevent the possibility that the endoscope 1 may be used next time, the method further includes, in one embodiment:

after the endoscope 1 leaves the human body, acquiring the time length extension data sent by the authorization shield;

if the time length extension data is greater than the preset time extension range, it is judged that the time extension is abnormal, thereby marking that the endoscope 1 has been used.

Therefore, after the endoscope 1 leaves the human body, the controller or the host 4 can acquire the time length extension data sent by the authorization shield; if the time length extension data is larger than the preset time extension range, judging that the time extension is abnormal, and marking that the endoscope 1 has been used in the endoscope 1 identity database. Therefore, if the endoscope 1 is electrically connected to the connection cable 3 again, the history of use can be recognized by the connection cable 3, and the secondary use can be prevented. The preset time extension range is determined by a manufacturer after finishing statistics according to time extension data of all the authorized shields, so that the time delay duration is ensured to be matched with the time delay duration under normal conditions.

Example 3

Referring to fig. 3, as an embodiment of the present invention, a detection system includes an endoscope 1, a host 4, and a connection cable 3, where the connection cable 3 connects the endoscope 1 and the host 4, and the detection system is used for detecting by the endoscope detection method described in embodiment 1.

Specifically, the connection cable 3 is electrically connected between the handle 12 and the host computer 4 to transmit signals therebetween. The signal transmission direction may include a control signal transmitted from the host computer 4 to the endoscope 1, or may include an image signal transmitted from the endoscope 1 to the host computer 4, an operation state feedback signal of the endoscope 1, and the like.

Referring to fig. 4 to 6, fig. 4 is a schematic structural diagram of a connecting cable 3 according to an embodiment of the present application. Fig. 5 is another view of the connecting cable 3 of fig. 4. Fig. 6 is a partial schematic view of the structure of fig. 4.

Specifically, the connection cable 3 includes a first communication interface 31, a cable portion 33, and a controller. The first communication interface 31 is used for being spliced with the handle 12 of the endoscope 1 so as to receive and transmit various communication signals with the endoscope 1; one end of the cable section 33 is connected to the first communication interface 31, and the other end is connected to the host 4; the plugging and unplugging number recording module is electrically connected with the first communication interface 31 to record the plugging and unplugging number between the endoscope 1 and the first communication interface 31 and determine the used number of times of the endoscope 1 according to the plugged and unplugged number of times; the controller is electrically connected with the plugging frequency recording module, so as to control the host 4 and the endoscope 1 to stop signal transmission or send out alarm information when the plugging frequency is larger than the first preset frequency.

The handle 12 is provided with a handle interface, and the first communication interface 31 of the connecting cable 3 and the handle interface can be detachably connected in a plug-in mode, so that the connecting cable 3 can be repeatedly used by replacing the endoscope 1, and the use cost of the endoscope 1 is reduced.

Illustratively, the cable portion 33 includes a plurality of signal transmission lines, and a protective sleeve surrounding the signal transmission lines. The plurality of signal transmission lines are used for transmitting different communication signals, and of course, in some cases, one signal transmission line may be multiplexed to transmit two or more communication signals, which is not limited herein.

The communication interface where the connection cable 3 is connected to the host 4 is referred to herein as a second communication interface. After the first communication interface 31 is plugged into the handle interface on the handle 12 and the second communication interface is electrically connected to the host 4, the cable portion 33 can transmit the communication signal between the endoscope 1 and the host 4. The communication signals herein include, but are not limited to, power supply signals, image compression information, endoscope 1 operating voltage signals, operating current signals, operating timing control signals, and the like.

The connecting cable 3 further comprises a plug frequency recording module. Illustratively, when the endoscope 1 is required to be used, after the first communication interface 31 is plugged into the handle interface on the handle 12 and the second communication interface is electrically connected to the host 4, the host 4 may send an electrical signal to the endoscope 1 through the cable portion 33, where the electrical signal may be a power signal for power supply or a control signal. During the use of the endoscope 1, the first communication interface 31 is in plug connection with the handle interface on the handle 12, and the electric signal is continuously transmitted, so that the electric signal is detected by the plug-in number recording module. When the operation of the endoscope 1 is completed, the first communication interface 31 is disconnected from the handle interface, the electrical signal is interrupted, and at this time, the plugging frequency recording module can detect the interruption of the electrical signal. The number of times of insertion and removal between the endoscope 1 and the first communication interface 31 is recorded by the insertion and removal number recording module, so that the number of times of use of the endoscope 1 can be determined.

In a specific embodiment, the plug number recording module may be constructed by a trigger and a counter circuit. When there is an electrical signal on the first communication interface 31, the trigger is triggered, thereby sending a signal to the counter, which counts up. The counter is electrically connected with the controller to synchronize the counting result to the controller; the first communication interface 31 may be provided with a conductive contact and a counting circuit, and when the first communication interface 31 is plugged with the handle interface to be electrically connected, a current flows through the conductive contact to trigger the counting circuit to count up.

More specifically, the controller may be further configured to obtain a historical number of plugging times between the endoscope 1 and the connection cable 3 after the host 4 and the endoscope 1 are electrically connected, and when the historical number of plugging times of the endoscope 1 is less than or equal to a first preset number of times, communicate between the host 4 and the endoscope 1, and monitor a plugging operation between the endoscope 1 and the host 4, where the plugging operation includes a plugging operation and a unplugging operation; when the endoscope 1 and the host 4 complete one-time plugging operation, based on the historical plugging times, recording that the plugging times of the endoscope 1 are increased once; when the number of plugging times is larger than the first preset number of times, the control host 4 and the endoscope 1 stop signal transmission or send out alarm information.

In some embodiments, the controller may be an MCU, a single chip microcomputer. In one embodiment, the controller and the plug count recording module may be implemented by a control chip. The chip can also be an MCU or a singlechip, and an appropriate interface circuit is built between the counting end of the MCU and the first communication interface 31 so as to realize that the MCU automatically counts the electric communication times of the first communication interface 31. When the counting result is larger than the preset times, the MCU generates an interrupt display instruction, and the host 4 stops signal transmission with the endoscope 1 in response to the interrupt display instruction so as to prevent the endoscope 1 from being used continuously, thereby achieving the aim of preventing the endoscope 1 from being used secondarily.

The reference number is generated by the unavoidable insertion and extraction operation of the endoscope 1 before the endoscope is not used for the operation, because of the production or test requirements. The reference number of times may be set to 0, or any number greater than 0.

Therefore, if the number of times of historical insertion and extraction between the endoscope 1 and the connection cable 3 is acquired to be equal to or less than the reference number of times, this indicates that the endoscope 1 is not used, and there is no risk of secondary use, and thus can be used for the current operation.

However, in another embodiment, when the host computer 4 and the endoscope 1 are electrically connected, the controller is further configured to stop signal transmission between the host computer 4 and the endoscope 1 or send out an alarm message when the number of times of historical insertion and extraction of the endoscope 1 is greater than the reference number.

In an embodiment, the connection cable 3 further includes an alarm module electrically connected to the pluggable frequency recording module, for sending out alarm information to prompt medical staff that the endoscope 1 has a secondary use risk when the number of times the endoscope 1 has been used is greater than or equal to a preset number of times. Alternatively, the alarm module sends an alarm signal to the controller of the connection cable 3, which forcibly disconnects the communication between the endoscope 1 and the host 4 to avoid that the endoscope 1 is continuously used. The controller may send an interrupt signal to the host computer 4, and the host computer 4 may stop displaying the image information acquired from the endoscope 1.

In the related art, the medical staff holds the handle 12 of the endoscope to perform the operation, and the distance between the host 4 and the medical staff is relatively long, typically more than 1 meter, which requires that the video information displayed by the display device be enlarged as much as possible during the operation of the medical staff. The other working state information of the endoscope 1 equipment is displayed on the display equipment relatively smaller, so that medical staff can not acquire the working state of the endoscope 1 in real time easily, and the smooth operation is affected.

Therefore, in order to make the medical staff better aware of the working state information of the endoscope 1 during the operation, in an embodiment, the connection cable 3 further includes a display module 32, the display module 32 includes a housing 321 and a display screen 322, and the display screen 322 is disposed on the housing 321; the first communication interface 31 is located on one end of the casing 321, and the cable portion 33 is penetrated from the other end of the casing 321 and connected to the host 4; the display screen 322 is electrically connected to the plug-in number recording module, so as to display the used number of the endoscope 1 determined by the plug-in number recording module. Of course, the display screen 322 may also be electrically connected to a plurality of signal transmission lines in the cable portion 33, so as to acquire a real-time operation state signal of the endoscope 1 and display corresponding operation state information.

In an embodiment, the display content of the display screen 322 may include the current number of times the endoscope 1 has been used, and when the connection cable 3 is electrically connected between the host computer 4 and the endoscope 1, the display screen 322 instantly displays the current number of times the endoscope 1 has been used, so that the operator quickly learns the historical use condition of the endoscope 1, and the secondary use of the endoscope 1 is effectively avoided. Also, the display content of the display screen 322 may further include various kinds of operation parameter information of the endoscope 1.

In this embodiment, through the design of the display screen 322 on the connection cable 3, the working state information of the endoscope 1 does not need to be displayed on the screen of the host computer 4, or is displayed in a smaller occupied area, so that the screen of the host computer 4 can further enlarge the image picture, and the user can operate the operation more accurately.

In addition, the design of the position of the display screen 322 on the connecting cable 3 accords with the ergonomic design, so that when an operator performs an operation by holding the handle 12 of the endoscope 1, the display screen 322 is positioned at the tiger mouth of the palm, and the display surface is positioned at the optimal position of the sight line, thereby being convenient for a user to intuitively see the information on the display screen 322.

In a specific embodiment, the housing 321 is cylindrical, and the display screen 322 is disposed vertically in the radial direction of the connector. The display screen 322 is vertically disposed in the axial direction of the housing 321. The design ensures that the information displayed on the display is in the optimal visual angle range when a user operates the handle 12 of the endoscope 1, thereby improving the convenience of information checking.

And the cross-sectional diameter length of the housing 321 may be designed to be 1cm to 3cm, and the length of the housing 321 in its own radial direction is 0.5cm to 3cm. Which is adapted to the size of the palm of the human hand to facilitate the user's grip on the housing 321.

In a specific embodiment, the cross section of the casing 321 may be elliptical, which is opposite to the circular design, so that the contact area with the hand can be increased during the plugging operation, and the plugging operation is convenient for the user. The major axis of the oval shape may be 1cm-3cm and the length of the housing 321 in its own radial direction may be 0.5cm-3cm.

Referring to fig. 7, fig. 7 is a schematic view of a portion of the structure of the housing 321 in fig. 4. In an embodiment, anti-skidding patterns 3211 may be further disposed on the outer surface of the casing 321, so that when the first communication interface 31 is plugged, friction force between the first communication interface and the palm can be increased, and quick and effective plugging can be achieved.

In a specific embodiment, the housing 321 has a handle interface thereon that is removably coupled to the display. The detachable connection mode can be in buckle connection or plug connection. The separation of the display and the casing 321 is realized in this embodiment, so that the display screen 322 and the casing 321 can be provided as separate products, and the cost of the updated products of hospitals is reduced.

In the related art, the endoscope 1 company selects to design a dedicated interface by itself to prevent the mixed use of the respective devices, thereby forming a market barrier. In an embodiment of the present application, the first communication interface 31 is a universal interface, and may specifically include one or more of an HDMI interface, a USB interface, and a Type-C interface. It should be understood that the handle interface on the corresponding handle 12 in this embodiment is of the same type as the first communication interface 31. The embodiment reduces the workload of designing a new special port by updating the communication protocol when the connection cable 3 is updated, can be used in other endoscope 1 products, and has wide usability.

Further, in an embodiment, the endoscope 1 includes an insertion portion 11, and an ambient light sensor is disposed on the insertion portion 11, where the ambient light sensor is used to detect the environment of the endoscope 1; the connection cable 3 further comprises a first timing circuit, and the first timing circuit is electrically connected with the first communication interface 31; the first timer circuit is electrically connected with the ambient light sensor, so that when the ambient light sensor detects that the endoscope 1 enters the subject, the first timer circuit starts to record the electrical communication duration between the endoscope 1 and the host 4, and the display is used for displaying the electrical communication duration.

The ambient light sensor can sense the current environment where the bending part 13 of the endoscope 1 is located, and illustratively, when the red light proportion in the environment is detected to be increased to about 50%, the bending part 13 is judged to have entered a human body, and at the moment, the ambient light sensor sends a timing signal to the first timing circuit to start timing, and the timing duration is displayed on the display.

Further, in order to further avoid that the endoscope 1 is used secondarily, an interface breaking device is provided at the first communication interface 31 of the connection cable 3, and the interface breaking device is used for breaking the handle interface after the handle interface is separated from the first communication interface 31. The type of damage may be mechanical damage to the handle interface or electrical damage to the handle interface. The interface destruction device can destroy the handle interface when the use frequency detection device detects that the use frequency of the endoscope 1 is greater than the preset frequency; when the bending portion 13 is detected by the ambient light sensor, the handle interface may be broken when the handle interface is separated from the connection cable 3.

The cable portion 33 has a fault signal line inside for transmitting a fault signal of the endoscope 1. The fault signal lines can be multiple to reflect fault conditions of the image acquisition module, the illumination optical module, the pump group and the like. In one embodiment, the controller is electrically connected to the fault signal line to parse the fault signal and display the fault information on the display screen 322.

In a specific example, the controller is electrically connected to the first communication interface 31 and the second communication interface of the connection cable 3, and when the controller determines that the connection cable 3 is disconnected from the endoscope 1 or the connection cable 3 is disconnected from the host 4 by detecting the connection state of the first communication interface 31 and the second communication interface during the operation of the endoscope 1, the controller controls the display to display abnormal connection state information.

In another embodiment, if a fault occurs during the operation, a fault code is displayed on the display screen 322; the fault code is indirect, so that medical staff can know the fault source of the endoscope 1 in time. The fault signal lines are simultaneously electrically connected to the host computer 4 to display specific fault information on the host computer 4 display module 32 so that the specific information of the fault can be timely known when the meaning of the fault code is not clear to medical staff.

The cable portion 33 has an image transmission line therein for transmitting an image signal collected by the image collection module. The image transmission line is electrically connected to the host computer 4 through the cable portion 33 to display an image captured by the endoscope 1 on the host computer 4. In one embodiment, the controller is also electrically connected to the image transmission line to analyze the image signal, and display the analyzed image on the display screen 322, so as to realize dual-screen synchronous display with the display module 32 of the host 4. Here, the display magnification of the display screen 322 may be higher than that of the display module 32 of the host 4, so that partial and finer image display is realized.

The examples, embodiments and technical features in the present application may be combined with each other without any conflict.

The embodiments of the present invention are all preferred embodiments of the present invention, and are not intended to limit the scope of the present invention in this way, therefore: all equivalent changes in structure, shape and principle of the invention should be covered in the scope of protection of the invention.
