Description

Electric endoscope anastomat and control method and control device thereof

Technical Field

The present disclosure relates to, but not limited to, stapler technologies, and in particular, to a control method and a control device for an electric endoscopic stapler, and an electric endoscopic stapler.

Background

The stapler replaces the traditional manual suture and utilizes titanium nails to perform separation and anastomosis on tissues. The anastomotic nails are blocked by the front nail anvil after penetrating through the two layers of tissues and are bent inwards to form B-shaped staggered arrangement, so that the two layers of tissues are permanently nailed together. Since small blood vessels can pass through the gaps of the "B" shaped staples, the blood supply at the suture site and the distal end thereof is not affected. Because the anastomotic nails are arranged regularly and have equal intervals, the defects of over-sparse and over-dense manual suture, over-tight and over-loose ligation and the like are avoided, the good healing of tissues is ensured, and the operation time is shortened.

Endoscopic staplers make it possible to perform surgery through smaller incisions. This results in less tissue damage than conventional surgery. Through a small incision, the surgeon may insert a tiny light source, camera, and surgical instrument. The surgeon guides the operation of the surgical instruments to perform the procedure through the images transmitted to the monitor. It causes less damage than traditional operation, and laparoscopic surgery has many advantages: the hospital stay is shorter (most cases), the postoperative pain is less, the patient can return to the working position earlier, and the scar is smaller.

The endoscope anastomat is widely applied to the fields of thoracic surgery, gastrointestinal surgery, hepatobiliary, splenic-pancreatic surgery, general surgery, urinary surgery and other operations, and is used for treating gastric cancer, weight-reducing gastrectomy, rectal cancer, colon cancer, bronchogenic carcinoma, lung cancer, chronic obstructive pulmonary disease, lung cyst, duodenal tumor, esophageal cancer, cirrhosis portal hypertension and other diseases.

At present, a special suturing device for an endoscope, namely a common one-time linear cutting endoscope anastomat, has six rows of suturing nails, a nail box is internally provided with a brand new blade, and the blade cuts off tissues from the middle when the suturing nails are closed, so that three rows of suturing nails at two sides can finish the functions of suturing, stopping bleeding and the like. At present, the proportion of the foreign minimally invasive surgery reaches 80-90 percent, but the proportion of the best hospital minimally invasive surgery in China reaches 70 percent, and the proportion of the second and third-line hospital minimally invasive surgery is lower. Therefore, the minimally invasive surgery still has a large development space in China. Among them, laparoscopic surgery is a newly developed minimally invasive method, which is an inevitable trend for the development of future surgical methods.

In actual use at present, the suturing device special for the endoscope mainly has two types: one is a manual endoscope anastomat, and the other is an electric endoscope anastomat.

The manual endoscope anastomat mainly realizes the forward movement of a cutting knife by a rack and a triggering propelling piece, and the backward movement needs to be manually pulled back. The nail bin assembly is opened and closed by pushing the inclined plane on the nail abutting seat by a cutter pin on the cutting knife so as to realize the opening and closing of the nail abutting seat. The whole structure is relatively simple, the operation is complex, the stability of the instrument in working is poor, and the change of the firing force is obvious. The speed and the speed of the transmission of the instrument are greatly influenced by manual operation, and particularly the difference of the gripping power of each person is large. The result is that the cutting blade cuts tissue at a slower rate, which can easily cause irregularities in the cut tissue surface. The speed of the nail pushing sheet is also low, so that the problems of poor nail shape and the like are easily caused, and the final effect of the operation is easily influenced.

The electric endoscope anastomat comprises a storage battery, a circuit control system, a miniature motor with a speed reducer, a transmission system, a safety system and the like. Through the electromechanical combination, the operation becomes simple, the stability of the apparatus during operation that can be fine control, use and obtain extensive popularization. Compared with the traditional endoscope anastomat, the electric endoscope anastomat has the following advantages besides the advantages of the traditional endoscope anastomat: 1) the tissue cutting and suturing functions are automatically realized, so that the instrument is stably fired in the operation process, and the risk of manual intervention on the instrument is reduced; 2) the anastomotic nail has good forming and regular tissue incision; 3) the electric operation is simple, convenient and quick, and the operation time is greatly shortened.

In recent years, the use of staplers in surgery has become relatively common, subject to factors such as the rapid increase in the amount of surgery, particularly minimally invasive surgery. The clinical utilization rate of the direct prefecture market exceeds 90%, the grade market exceeds 70%, the basic level is limited by the level of doctors, the clinical utilization rate is relatively low, a large lifting space is provided, and particularly, the electric endoscope linear cutting anastomat has a larger requirement on clinical application. How to further improve the operation convenience and the use safety of the electric endoscope anastomat is a research hotspot of technicians in the field to meet the increasing market demand.

The embodiment of the application provides a control method for an electric endoscope anastomat. As shown in fig. 4 to 7, the electric endoscopic stapler comprises a stapler body 1 and a cartridge assembly 2 connected to the stapler body 1. The stapler body 1 includes: a rotating head assembly 12, a display assembly 13, a body assembly 11 and a battery assembly 14.

The rotating head assembly 12 and the body assembly 11 are fixedly connected along the axial direction of the rotating head assembly 12 and can rotate 360 degrees around the axis of the rotating head assembly. The display component 13 is assembled with the body component 11 through the upper and lower clamping grooves and is detachably connected. The battery assembly 14 is assembled with the body assembly 11 through a card slot and is detachably connected. Cartridge assembly 2 is assembled with jaw 121 of rotary head assembly 12 and is removable for replacement with a new cartridge assembly 2.

As shown in fig. 7 and 8, the body assembly 11 includes various functional operating members, including but not limited to the following: a closure trigger 111, a confirmation button 112, a fire button 113, a reverse button 114, and a reset button 115.

Closing the trigger 111: the opening and closing of the closure trigger 111 corresponds to the opening and closing of the jaws 121, namely: when the closing trigger 111 is closed, the jaws 121 are closed, that is, the cartridge assembly 2 is closed; the closure trigger 111 is opened and the jaws 121 are opened, i.e., the cartridge assembly 2 is opened.

Confirmation key 112: and the lock is matched with a safety system of the nail bin assembly 2 in a linkage manner, and an unlocking instruction is input when the confirmation key 112 is pressed, so that the nail bin assembly 2 is unlocked. The confirmation button 112 is used for confirming the time when the tissue is pressed and selecting the time when the tissue is cut before the cutting tissue is fired, and confirming whether the operation can be fired. The key is mainly arranged to prevent the possibility of error firing of the instrument under the condition of error operation of a doctor.

The trigger button 113: and the trigger button 113 is linked and matched with a driving device of the nail bin assembly 2, and a trigger instruction is input when the trigger button 113 is pressed, so that the nail bin assembly 2 is started, and the trigger operation is executed.

Reverse key 114: and the reverse button 114 is pressed in linkage fit with a driving device of the nail bin assembly 2, namely, an electric backspacing instruction is input, and the electric backspacing instruction is used for controlling the nail bin assembly 2 to electrically backspace.

Reset button 115: in cooperation with the locking device of the jaw 121, the reset button 115 is pressed to unlock the jaw 121, so that the jaw 121 can be opened.

The rotating head assembly 12 is provided with a knob 122, when the jaw 121 needs to be bent to clamp the tissue, the knob 122 of the rotating head assembly 12 only needs to be rotated to swing the jaw 121 left and right.

In use, the surgeon would open the jaws 121, install the cartridge assembly 2, then install the battery assembly 14 and energize the instrument, inserting the instrument into the patient's lesion, and close the trigger 111. The surgeon then presses the confirmation button 112 at the appropriate time to unlock the cartridge module 2 and then presses the firing button 113 to fire. After the percussion is finished, the nail bin assembly 2 automatically retracts to the initial position. If the cartridge module 2 cannot complete the firing and cannot advance further, the surgeon is required to press the reverse button 114 to electrically retract the cartridge module 2. If the electric retraction fails, manual operation by a surgeon is required to retract the cartridge assembly 2.

As shown in fig. 1, the control method includes:

step S102: after electrifying, when confirming that the nail bin assembly is assembled and closed, starting timing;

step S104: and determining whether to unlock the nail cartridge assembly according to the timing duration and the unlocking instruction.

The control method provided by the embodiment of the application can start timing after electrification and when the nail bin assembly 2 is confirmed to be assembled and closed, and determines whether to unlock the nail bin assembly 2 according to timing duration and an unlocking instruction, so that a doctor can conveniently perform firing operation at a proper time, the doctor can be prevented from mistakenly firing an instrument under the condition of mistakenly operating the instrument, and the use convenience and the use safety of the electric endoscope anastomat are improved.

Specifically, when the cartridge assembly 2 is fully assembled and closed after power is applied, it indicates that the instrument is beginning to squeeze tissue. At the moment, timing is started, and the timing duration is the squeezing duration of the instrument on the tissues. Because the locking of the nail bin assembly 2 is released for triggering operation only when the squeezing time is proper, the instrument has a better using effect. Therefore, when the locking of the cartridge module 2 is released to start the firing operation is a key operating point of the electric endoscopic stapler during the use process.

Conventionally, the unlocking of the cartridge module 2 is subjectively determined directly by the unlocking instruction of the doctor. On the one hand, doctors can perform rough timing according to own subjective experience or by using an external timing tool (such as a clock or other equipment), and the starting time and the timing duration of the timing are difficult to avoid the situation that the accuracy is not enough and even a large deviation is generated. On the other hand, the doctor may also cause the cartridge module 2 to be unlocked due to misoperation, and further cause the misoperation of firing, thereby affecting the use effect.

According to the scheme, the timing can be automatically started when the instrument starts to squeeze the tissues, the timing is accurate, a doctor does not need to additionally time, and therefore the operation convenience of the product is improved. On the other hand, the unlocking of the nail bin assembly 2 is not subjectively determined by the unlocking instruction of a doctor but is determined by dual factors of the timing duration and the unlocking instruction, so that the phenomenon that the locking of the nail bin assembly 2 is mistakenly unlocked and then mistaken firing operation is caused due to subjective timing deviation or misoperation of the doctor can be effectively avoided, and the use safety of the product is improved.

In an exemplary embodiment, determining whether to unlock the cartridge module 2 based on the timed length and the unlock command includes:

when the timing duration is longer than or equal to the set timing duration, receiving an unlocking instruction, and unlocking the nail bin assembly 2 to enable the nail bin assembly 2 to be fired;

when the timing duration is shorter than the set timing duration, an unlocking instruction is received, and the nail bin assembly 2 is kept locked to limit the percussion of the nail bin assembly 2.

The set time period may be a suitable pressing time period of the device to the tissue, and may be set empirically, such as 10s or 15 s.

When the timing duration is longer than or equal to the set duration, the tissue is squeezed by the instrument for a proper squeezing duration, and the firing operation can be carried out. Therefore, when an unlocking instruction is received at this time, the locking of the cartridge module 2 can be released, so that the cartridge module 2 can be fired.

When the timing duration is shorter than the set duration, the tissue squeezing by the instrument does not reach the proper squeezing duration, and the locking of the nail cartridge component 2 is not suitable to be released, so that the unlocking instruction received at the moment may be the unlocking instruction sent due to misoperation of a doctor. Therefore, when the unlocking instruction is received at this time, the cartridge module 2 is kept locked, so that the cartridge module 2 cannot be fired, and adverse effects caused by misoperation are prevented.

This is equivalent to double insurance on the nail bin assembly 2, and not only the insurance system locks on the mechanical structure, but also a set of insurance on the electric control is added, so as to prevent the nail bin assembly 2 from being mistakenly triggered due to misoperation.

In an exemplary embodiment, determining whether to unlock the cartridge module 2 according to the timing length and the unlock instruction further comprises:

after the unlocking instruction is received when the timing duration is shorter than the set timing duration, the unlocking instruction is received again, the timing duration is still shorter than the set duration when the unlocking instruction is received again, and the lock on the nail bin assembly 2 is released so that the nail bin assembly 2 can be fired.

After the unlocking instruction is received when the timing length is shorter than the set timing length, the unlocking instruction is received again, and the timing length is still shorter than the set timing length after the unlocking instruction is received again, which indicates that under the condition that the timing length is shorter than the set timing length, the doctor sends the unlocking instruction twice in sequence, and at the moment, the instrument executes the unlocking instruction to unlock the nail bin assembly 2, so that the nail bin assembly 2 can be fired.

Since the specific conditions of different patients vary widely, doctors need to reasonably select the specific time for the percussion operation according to the specific conditions of each patient. While it is most appropriate to unlock the cartridge module 2 after a set period of time for the firing operation, in a few cases, it may be necessary to perform the firing operation within the set period of time.

Therefore, according to the scheme of unlocking the nail bin assembly 2 through two unlocking instructions within the set time, the requirements of a doctor can be met, the doctor can reasonably select the specific time for unlocking the nail bin assembly 2 and triggering according to actual conditions, the use flexibility of the product is improved, the use scene range of the product is expanded, and the use experience of a user is improved. Of course, the cartridge module 2 may be unlocked by three or more unlocking commands within a set period of time.

after the unlocking instruction is received when the timing duration is less than the set timing duration, the lock on the nail bin assembly 2 is released until the timing duration is greater than or equal to the set timing duration, so that the nail bin assembly 2 can be fired.

After the unlocking instruction is received when the timing duration is less than the set timing duration, the doctor does not send the unlocking instruction again until the timing duration is greater than or equal to the set timing duration, and the fact that the last unlocking instruction is possibly misoperation of the doctor is shown. When the timing duration reaches the set timing duration, the appropriate squeezing duration is reached, and the lock on the nail bin assembly 2 is automatically released at the moment, so that the nail bin assembly 2 can be fired, a doctor does not need to send an unlocking instruction again, the instrument can be directly operated to fire, and the operation convenience of the product is improved.

In an exemplary embodiment, the set time period is in a range of 10s to 15 s.

According to the summary of clinical operation experience, in order to ensure that the squeezing time of tissues is controlled, the optimal squeezing time is generally 10s to 15s, and the optimal effect is achieved by performing the firing operation. Therefore, the set time period may be limited to a range of 10s to 15s, such as 10s, 11s, 12s, 13s, 14s, 15s, and the like.

Of course, the set time period is not limited to the above range, and may be adjusted as necessary.

In one example, the set time period is 10 s.

In another example, the set time period is 15 s.

In an exemplary embodiment, the control method further includes:

when the lock on the nail bin assembly 2 is released, a first prompt signal is sent out to prompt the nail bin assembly 2 to be unlocked;

when the locking of the cartridge component 2 is kept, a second prompt signal is sent out to prompt that the cartridge component 2 is not unlocked.

When the locking of the nail bin assembly 2 is released, a first prompt signal is sent, so that the unlocking of the nail bin assembly 2 can be clearly prompted to a doctor, the percussion operation can be performed, the doctor can know the information in time, and the use convenience of the product is improved.

Similarly, when the unlocking instruction is received when the set time length is not reached, and the nail bin assembly 2 is kept locked, a second prompt signal is sent, so that the condition that the nail bin assembly 2 is not unlocked by a doctor can be clearly prompted, and the doctor is indirectly prompted to check whether the nail bin assembly is misoperation or not. If the operation is wrong, the user can be triggered again after waiting for a certain time; if the operation is not misoperation, the unlocking instruction can be sent again to confirm that the self really needs to carry out the firing operation in advance.

In an exemplary embodiment, the first cue signal comprises: the flashing forward arrow is displayed and is consistent with the firing direction, so that the doctor can understand the arrow conveniently. The second cue signal comprises: and displaying the timing duration of the flicker.

Wherein, the flicker frequency of the forward arrow and/or the timing duration can also be adjusted according to the requirement. Such as: when the set time length is 10s, the lamp flickers once per second; when the set time period is 15s, it blinks twice per second.

Of course, the first prompt signal and the second prompt signal are not limited to the above-mentioned schemes, and other prompt modes, such as voice, music, picture, video, etc., may be used for prompting.

In an exemplary embodiment, the control method further includes: further comprising:

after the lock on the nail bin assembly 2 is released, a firing instruction is received, the nail bin assembly 2 is controlled to fire, and a third prompt signal is sent out;

and after the nail bin assembly 2 is controlled to finish the firing, a fourth prompt signal is sent out and the nail bin assembly 2 is controlled to automatically retract to the initial position.

After the locking of the nail bin assembly 2 is released, a firing instruction is received, the firing operation is executed to control the nail bin assembly 2 to fire, a third prompt signal is sent out, the third prompt signal can prompt that the instrument is in a firing state at present, and a doctor can conveniently and timely know the firing state of the instrument.

After the percussion operation is finished, the nail bin assembly 2 is controlled to automatically return to the initial position, and the nail bin assembly 2 is convenient to replace for next percussion. And a fourth prompt signal is sent out at the moment, so that the doctor can timely know that the instrument is fired at the current time, and the nail bin assembly 2 can be timely replaced so as to perform next firing.

In an exemplary embodiment, the third cue signal includes: and displaying a normally bright forward arrow, wherein the forward arrow is changed from a flashing state to a normally bright state, and the forward arrow is indicated to be in a firing state. The fourth cue signal includes: and displaying a normally bright retreat arrow to indicate that the retreat is finished and the retreat direction is consistent, so that the retreat is convenient for a doctor to understand.

Of course, the third prompt signal and the fourth prompt signal are not limited to the above-mentioned schemes, and other prompt modes, such as voice, music, picture, video, etc., may be used for prompting.

In an exemplary embodiment, the control method further includes:

when the current is detected to exceed a set threshold value in the firing process of the nail bin assembly 2, a fifth prompt signal is sent to prompt the input of an electric backspacing instruction;

and when the electric backspacing instruction is received and the electric backspacing nail cartridge assembly 2 fails, a sixth prompt signal is sent to prompt the manual backspacing nail cartridge assembly 2.

When the firing operation is not completed, but the instrument cannot continue to fire forward, the system automatically starts the protection mode at the moment, which may cause excessive current in the circuit due to excessive cutting force. Therefore, when the current exceeds the set threshold value in the firing process of the nail bin assembly 2, a fifth prompt signal is sent out, so that a user can know the state in time, an electric backspacing instruction can be input in time, and the nail bin assembly 2 can be backspaced in time.

When the electric backspacing instruction is received but the electric backspacing nail bin assembly 2 fails, the instrument is indicated to be in fault, and a sixth prompt signal is sent out at the moment, so that a user can know the state in time, the operation handle 116 can be operated in time in a manual mode, the nail bin assembly 2 is made to backspace, and the disadvantages of the patient are reduced as much as possible.

In an exemplary embodiment, the fifth cue signal includes: and displaying the first error code. The sixth cue signal includes: and displaying the second error code.

Of course, the fifth prompt signal and the sixth prompt signal are not limited to the above-mentioned schemes, and other prompt modes, such as voice, music, pictures, video, etc., may be used for prompting.

In an exemplary embodiment, the control method further includes:

and when the nail bin assembly 2 is electrically retracted and opened, a seventh prompt signal is sent to prompt that the use is finished.

No matter whether the nail bin assembly 2 automatically backs after being fired or automatically backs by inputting an electric back-off instruction, when the nail bin assembly 2 is electrically backed off and opened, a seventh prompt signal is sent to prompt that the use is finished, and a user can conveniently know the state of the completion of the back-off in time.

In an exemplary embodiment, the seventh cue signal is: the back arrow is off.

Of course, the seventh prompt signal is not limited to the above scheme, and other prompt modes, such as voice, music, picture, video, etc., may also be used for prompting.

In an exemplary embodiment, as shown in fig. 2, before step S102, the control method further includes:

step S100: carrying out system self-check after electrifying to confirm whether the electric endoscope anastomat is normal or not;

step S106: and when the abnormity of the electric endoscope anastomat is confirmed, an eighth prompt signal is sent to prompt the replacement of the electric endoscope anastomat.

After the power is on, system self-checking is firstly carried out to confirm whether the electric endoscope anastomat is normal or not, so that a doctor can know whether the instrument is normal or not clearly. If the electric endoscope anastomat is confirmed to be normal, the doctor can use the anastomat normally. If the abnormity of the electric endoscope anastomat is confirmed, an eighth prompt signal is sent to prompt the abnormal state of the appliance of the doctor, so that the doctor can replace the new electric endoscope anastomat conveniently in time, and inconvenience or other adverse effects caused by the need of replacing the appliance temporarily due to the use of the abnormal appliance in the operation are avoided.

The scheme enables the electric endoscope anastomat to have an instrument self-checking function. Before the instrument is used, whether the switches of all parts are in the initial state or not is automatically detected, or whether the switches are in the initial position state or not is determined and detected before the instrument finishes one-time cutting and replacing the nail cartridge assembly 2 and cuts again. If yes, the instrument can be used normally; if not, an error prompt is sent out.

In an exemplary embodiment, the eighth cue signal is: displaying a second error code or displaying a black screen. Thus, the instrument has only two error codes, so that a doctor can easily distinguish the fault state of the instrument so as to make a correct response. When the first error code (e.g., E00) is displayed, it indicates that the instrument is only in the over-current protection mode and can still be used normally. When a second error code (e.g., E11) is displayed, it indicates that the instrument is malfunctioning and is not being used properly, requiring replacement with a new instrument.

Of course, the eighth prompt signal is not limited to the above-mentioned scheme, and other prompt modes, such as voice, music, picture, video, etc., may be used for prompting.

In an exemplary embodiment, between step S102 and step S104, the control method further includes at least one of the following steps:

after the nail bin assembly 2 is closed, a doctor can repeat the opening and closing process according to the requirement, in the process, only when the nail bin assembly is closed for the last time, the tissue is squeezed, and therefore the timing duration and the unlocking instruction of the last time are used as the judgment basis for judging whether the nail bin assembly 2 is unlocked or not.

In an exemplary embodiment, the control method further includes:

and after the power is switched on, the residual electric quantity of the electric endoscope anastomat is displayed.

Because the electric endoscope anastomat is powered by a battery generally, the residual electric quantity is displayed after the electric endoscope anastomat is powered on, so that a doctor can know the electric quantity condition in time, and the battery or the instrument can be replaced in time.

The beneficial effects of the foregoing embodiments can be understood by referring to the description of the foregoing embodiment of the control method, which is not described herein again.

The working principle of the electric endoscopic stapler according to the above embodiment is described below with reference to the accompanying drawings.

1) The self-checking function of the instrument:

before the instrument is used, the cartridge assembly 2 is installed first, and then the battery assembly 14 is installed. When the battery assembly 14 is installed, the circuitry in the instrument is energized. The system automatically detects whether the relative positions of the switches of the instrument are initial positions. When the detection confirms that the switches are in the initial positions, the instrument can be normally used. When the instrument display screen displays error E00 (i.e., displays a second error code, as shown in fig. 11), it indicates that the instrument initial position has changed. At the moment, the electric control part of the instrument fails to function, and the instrument should be replaced by a new instrument for use.

2) Closing and opening of the jaws 121:

the closing/opening movement of the closure trigger 111 corresponds one-to-one to the closing/opening movement of the jaws 121. In other words, closure trigger 111 is closed, jaws 121 are closed, and cartridge assembly 2 is closed, as shown in FIG. 8. The closure trigger 111 is opened, the jaws 121 are opened and the cartridge assembly 2 is opened, as shown in FIG. 7.

For ease of operation, the firing button 113 is hidden inside the body when the closure trigger 111 is open. When the closure trigger 111 is closed, the firing button 113 leaks out of the body handle. This effectively prevents the firing button 113 from being used in conjunction with the closure trigger 111, which could result in inadvertent operation, as shown in FIGS. 7 and 8.

3) Oscillation of the jaws 121:

when the jaw 121 needs to be bent to a certain angle to clamp the tissue, the knob 122 on the rotating head needs to be twisted to swing the jaw 121 left and right (as shown in fig. 9 and 10).

4) Confirming and firing:

the display screen begins when the closure trigger 111 is closed, i.e., the jaws 121 and cartridge assembly 2 are closed.

When the timing time is longer than or equal to 10s (or 15s), the confirmation key 112 is pressed, and the forward arrow on the display screen begins to flash (i.e. a first prompt signal is displayed), which indicates that the nail bin assembly 2 is unlocked. At this time, the trigger button 113 is triggered, and the electric trigger function can be realized.

When the timing duration is less than 10s (or 15s), the confirmation button 112 is pressed, the second counting on the display screen begins to flash (i.e., the second prompt signal is displayed), and the firing is still invalid, which indicates that the locking of the cartridge module 2 is maintained. If the confirm button 112 is pressed again within the timing duration <10s (or 15s), the forward arrow on the display begins to blink (i.e., a first prompt signal is displayed), indicating that the cartridge module 2 has been unlocked. At this time, the trigger button 113 is triggered, and the electric trigger function can be realized.

When the timing duration is less than 10s (or 15s), the confirmation button 112 is pressed, the second counting flash (i.e., the second prompt signal is displayed) on the display screen is started, and the firing is invalid, so that the locking of the cartridge component 2 is kept. If the timing duration is longer than or equal to 10s (or 15s), the forward arrow on the display screen begins to flash (i.e. the first prompt signal is displayed) without pressing the confirmation button 112, which indicates that the cartridge module 2 is unlocked. At this time, the trigger button 113 is triggered, and the electric trigger function can be realized.

The confirmation button 112 is provided to ensure that the tissue squeezing time is controlled, and the optimal squeezing time is generally 10s-15s, and then the triggering operation is performed. If the doctor wants to perform the firing operation within 10s (or 15s), the doctor needs to press the confirmation button 112 twice within 10s (or 15s) to realize the electric firing function (as shown in fig. 8 and 12).

5) Electric/mechanical rollback:

after the instrument is fired, the instrument can automatically cut and retreat to the firing starting position, at the moment, the reset button 115 is pressed, the jaw 121 is automatically opened, and the use of the instrument is finished.

When the instrument firing is not completed, but the instrument cannot continue to fire forward, which may result in excessive current in the circuit due to excessive cutting force, the system automatically starts the protection mode, i.e., the display screen displays error E11 (i.e., displays the first error code, as shown in fig. 13). At this time, the doctor needs to press the reverse button 114 to electrically retract the handle until the electric retraction is completed, and then open the jaws 121 to complete the use.

When the electric retraction of the instrument fails, the display screen may be blank due to power supply problems or the display error is E00 (i.e. the second error code is displayed), and then the manual retraction (the display assembly 13 is removed and the operating handle 116 is moved) is required, and then the jaws 121 are opened to complete the use, as shown in fig. 14 and 15.

6) Instrument usage and electrical control principle (as shown in fig. 16 and 17):

the use process of the instrument is as follows: installing the nail bin assembly 2, installing the battery assembly 14, closing/opening a trigger, pressing a confirmation key 112, pressing a firing key 113, electrically firing, electrically retracting, pressing a reset key 115, and repeatedly installing a new nail bin assembly 2.

An electric control part: various key switches (closing/opening/reversing and the like) are mechanically limited and electrically controlled, and the switches are required to be sequentially pressed and triggered according to the operation flow sequence of the instrument. The signal recognition by the processor 31 system during the triggering of the switch determines whether the next step of the execution action can be currently performed. (such as forward rotation and reverse rotation of the motor, state reminding of the display screen, etc.). The process ensures that the mechanical part and the electric control part jointly provide guarantee for the safety of the operation of the instrument.

In summary, the control method and the control device for the electric endoscope anastomat and the electric endoscope anastomat provided by the embodiment of the application have the advantages of simple structure, low price, high product safety and stable product use performance, are effective products with high cost performance, and are beneficial to improving the market competitiveness of domestic electric endoscope anastomats.
