Description

Technical Field

[0001] The present invention relates to but is not limited to stapler technology, and in particular to a control method, a control device and an electric laparoscopic stapler for an electric laparoscopic stapler. Background Art

[0002] The stapler replaces the traditional manual suturing and uses titanium staples to separate and staple tissues. After passing through the two layers of tissue, the staples are blocked by the anvil in front and bend inward to form a "B" shape with mutually offset arrangement, which permanently staples the two layers of tissue together. Since small blood vessels can pass through the gaps of the "B"-shaped staples, it does not affect the blood supply to the suture site and its distal end. Since the staples are arranged neatly and at equal spacing, the defects of manual suturing such as too sparse or too dense and ligation too tight or too loose are avoided, which not only ensures good tissue healing, but also shortens the operation time.

[0003] Laparoscopic staplers make it possible to perform surgery through smaller incisions. This causes less damage to tissue than traditional surgery. Through smaller incisions, surgeons can insert tiny light sources, cameras, and surgical instruments. Surgeons use images transmitted to the monitor to guide the operation of surgical instruments to perform surgery. It causes less damage than traditional surgery. Laparoscopic surgery has many advantages: shorter hospital stays (in most cases), less pain after surgery, earlier return to work, and smaller scars.

[0004] Laparoscopic staplers are widely used in thoracic surgery, gastrointestinal surgery, hepatobiliary spleen and pancreas surgery, general surgery, urology and other surgical fields, and are used for gastric cancer, bariatric gastrectomy, rectal cancer, colon cancer, bronchial lung cancer, lung cancer, chronic obstructive pulmonary disease, lung cysts, duodenal tumors, esophageal cancer, portal hypertension due to cirrhosis and other diseases.

[0005] At present, the laparoscopic stapler, that is, the common single-use linear cutting laparoscopic stapler, has a total of six rows of staples. There are brand new blades in the stapler box. When the staples are closed, the blades cut the tissue from the middle, so that three rows of staples on each side can complete the functions of suturing and hemostasis. At present, the proportion of minimally invasive surgery abroad has reached 80%-90%, but the proportion of minimally invasive surgery in the best hospitals in China is only 70%, and the proportion of minimally invasive surgery in second- and third-tier hospitals is even lower. Therefore, there is still a lot of room for the development of minimally invasive surgery in my country. Among them, laparoscopic surgery is a newly developed minimally invasive method, which is an inevitable trend in the development of surgical methods in the future.

[0006] In actual use, there are two main types of laparoscopic staplers: one is a manual laparoscopic stapler, and the other is an electric laparoscopic stapler.

[0007] The manual laparoscopic stapler mainly relies on the rack and the firing propeller to advance the cutting knife, while the retraction needs to be manually pulled back. The opening and closing of the staple cartridge assembly relies on the knife pin on the cutting knife to push the inclined surface on the nail annulus to open and close the nail annulus. The entire structure is relatively simple, but the operation is complicated. The stability of the instrument is not good during operation, and the firing force varies significantly. The speed of the instrument transmission is greatly affected by manual operation, especially the grip strength of each person varies greatly. As a result, when the speed of the cutting knife cutting the tissue is sometimes fast and sometimes slow, it is easy to cause uneven surfaces of the cut tissue. The speed of the nail pusher is also sometimes fast and sometimes slow, which can easily cause problems such as poor nail shape and easily affect the final effect of the operation.

[0008] The electric laparoscopic stapler is composed of a battery, a circuit control system, a miniature motor with a reducer, a transmission system, and a safety system. Through the combination of electromechanics, the operation becomes simple, and the stability of the instrument during operation can be well controlled, and its use has been widely promoted. Compared with the traditional laparoscopic stapler, the electric laparoscopic stapler has the following advantages in addition to the advantages of the traditional laparoscopic stapler: 1) Automatic cutting and suturing of tissues, which makes the firing of the instrument more stable during the operation and reduces the risk of human intervention to the instrument; 2) The staples are well formed and the tissue incision is neat; 3) The electric operation is simple and quick, which greatly shortens the operation time.

[0009] In recent years, due to the rapid growth of surgical volume, especially minimally invasive surgery, the use of staplers in surgical operations has become relatively common. The clinical use rate in municipalities has exceeded 90%, and in prefecture-level cities it has exceeded 70%. Due to the limitation of doctors' level, the clinical use rate at the grassroots level is still relatively low, and there is a lot of room for improvement, especially for electric laparoscopic linear cutting staplers, which have a greater demand in clinical applications. How to further improve the convenience and safety of operation of electric laparoscopic staplers is a hot topic for technicians in this field to meet the growing market demand.

[0063] The present application embodiment provides a control method for an electric laparoscopic stapler. Figures 4 to 7 As shown, the electric laparoscopic stapler comprises a stapler body 1 and a stapler cartridge assembly 2 connected to the stapler body 1. The stapler body 1 comprises: a rotating head assembly 12, a display assembly 13, a body assembly 11 and a battery assembly 14.

[0064] The rotating head assembly 12 is fixedly connected to the body assembly 11 along the axial direction of the rotating head assembly 12 and can rotate 360° around its axis. The display assembly 13 is assembled with the body assembly 11 through the upper and lower card slots and is detachably connected. The battery assembly 14 is assembled with the body assembly 11 through the card slot and is detachably connected. The nail magazine assembly 2 is assembled with the jaws 121 of the rotating head assembly 12 and is detachable so as to replace a new nail magazine assembly 2.

[0065] like Figure 7 and Figure 8 As shown, the body assembly 11 includes a variety of functional operating parts, including but not limited to the following: a closing trigger 111, a confirmation button 112, a firing button 113, a reverse button 114 and a reset button 115.

[0066] Closing trigger 111: The opening and closing of the closing trigger 111 corresponds to the opening and closing of the jaw 121, that is, when the closing trigger 111 is closed, the jaw 121 is closed, that is, the nail magazine assembly 2 is closed; when the closing trigger 111 is opened, the jaw 121 is opened, that is, the nail magazine assembly 2 is opened.

[0067] Confirmation button 112: It is linked with the safety system of the staple cartridge assembly 2. Pressing the confirmation button 112 inputs an unlocking command to unlock the staple cartridge assembly 2. The confirmation button 112 is used for the doctor to confirm the time when the tissue is squeezed and the timing when the tissue is cut before firing the tissue, and to confirm whether the firing operation is possible. The setting of this button is mainly to prevent the doctor from accidentally firing the instrument in the case of misoperation.

[0068] The firing button 113 is linked with the driving device of the staple cartridge assembly 2. Pressing the firing button 113 inputs a firing instruction to start the staple cartridge assembly 2 and execute a firing operation.

[0069] Reverse button 114: cooperates with the driving device of the staple cartridge assembly 2, and pressing the reverse button 114 inputs an electric retraction instruction for controlling the electric retraction of the staple cartridge assembly 2.

[0070] Reset button 115: cooperates with the locking device of the jaw 121, and pressing the reset button 115 releases the lock on the jaw 121, so that the jaw 121 can be opened.

[0071] The rotating head assembly 12 is provided with a knob 122 . When the jaws 121 need to be bent to a certain angle to clamp tissue, the jaws 121 can be swung left and right by simply rotating the knob 122 of the rotating head assembly 12 .

[0072] During use, the doctor needs to first open the jaws 121, install the staple cartridge assembly 2, then install the battery assembly 14 to power on, insert the instrument into the patient's affected area, and close the trigger 111. After that, the doctor needs to press the confirmation button 112 at the right time to unlock the staple cartridge assembly 2, and then press the firing button 113 to fire. After the firing is completed, the staple cartridge assembly 2 will automatically retract to the initial position. If the staple cartridge assembly 2 cannot complete the firing and cannot continue to move forward, the doctor needs to press the reverse button 114 to make the staple cartridge assembly 2 retract electrically. If the electric retraction fails, the doctor needs to manually operate to retract the staple cartridge assembly 2.

[0073] like Figure 1 As shown, the control method includes:

[0074] Step S102: After power is turned on, when it is confirmed that the nail magazine assembly is assembled and closed, start timing;

[0075] Step S104: Determine whether to unlock the staple cartridge assembly according to the timing duration and the unlocking instruction.

[0076] The control method provided in the embodiment of the present application can start timing after power is turned on and it is confirmed that the staple magazine assembly 2 is assembled and closed, and determine whether to release the lock of the staple magazine assembly 2 based on the timing duration and the unlocking instruction. This makes it convenient for the doctor to perform the firing operation at the appropriate time, which helps prevent the doctor from accidentally firing the instrument due to misoperation of the instrument, thereby improving the convenience and safety of using the electric laparoscopic stapler.

[0077] Specifically, after power is turned on, when the staple cartridge assembly 2 is assembled and closed, it indicates that the instrument begins to compress the tissue. At this time, the timing starts, and the timing duration is the duration of the compression of the tissue by the instrument. Since the instrument has a better use effect only when the staple cartridge assembly 2 is unlocked and the firing operation is performed at the appropriate compression duration. Therefore, when to unlock the staple cartridge assembly 2 and start the firing operation is a key operating point during the use of the electric laparoscopic stapler.

[0078] Under normal circumstances, the unlocking of the nail magazine assembly 2 is directly determined by the doctor's unlocking instruction. On the one hand, the doctor can roughly time the time based on his own subjective experience or use an external timing tool (such as a clock or other equipment). The start time and the duration of the time are inevitably inaccurate or even have large deviations. On the other hand, the doctor may also cause the nail magazine assembly 2 to be unlocked due to misoperation, which may lead to an erroneous firing operation and affect the use effect.

[0079] This solution can automatically start timing when the instrument starts to compress the tissue, and the timing is more accurate, and the doctor does not need to count separately, thus improving the operational convenience of the product. On the other hand, the release of the lock of the nail magazine assembly 2 is not only determined by the doctor's unlocking instruction, but is determined by the timing duration and the unlocking instruction. This can effectively avoid the doctor's subjective timing deviation or misoperation, which may lead to the misunderstanding of the lock of the nail magazine assembly 2 and then the misfiring operation, thereby improving the safety of the product.

[0080] In an exemplary embodiment, determining whether to unlock the staple cartridge assembly 2 according to the timing duration and the unlocking instruction includes:

[0081] When the timing duration is greater than or equal to the set duration, an unlocking instruction is received, and the nail magazine assembly 2 is unlocked to enable the nail magazine assembly 2 to fire;

[0082] When the timing duration is less than the set duration, an unlocking instruction is received, and the nail magazine assembly 2 remains locked to restrict the nail magazine assembly 2 from firing.

[0083] The set time length may be a suitable compression time length of the tissue by the instrument, and may be set based on experience, such as 10s or 15s.

[0084] When the timing time is greater than or equal to the set time, it indicates that the compression of the tissue by the device has reached a suitable compression time and the firing operation can be performed. Therefore, when the unlocking instruction is received at this time, the lock of the nail magazine assembly 2 can be released, so that the nail magazine assembly 2 can be fired.

[0085] When the timing duration is less than the set duration, it indicates that the compression of the tissue by the instrument has not reached the appropriate compression duration, and it is not appropriate to unlock the nail magazine assembly 2 at this time. Therefore, the unlocking instruction received at this time may be caused by the doctor's misoperation. Therefore, when the unlocking instruction is received at this time, the nail magazine assembly 2 is kept locked, so that the nail magazine assembly 2 cannot be fired, so as to prevent adverse consequences caused by misoperation.

[0086] This is equivalent to providing double insurance for the nail magazine assembly 2, with an existing insurance system that locks the mechanical structure and an additional set of electronically controlled insurance to prevent accidental firing of the nail magazine assembly 2 due to misoperation.

[0087] In an exemplary embodiment, determining whether to unlock the staple cartridge assembly 2 according to the timing duration and the unlocking instruction further includes:

[0088] After receiving an unlock command when the timing duration is less than the set duration, the unlock command is received again and the timing duration is still less than the set duration when the unlock command is received again, the lock on the nail magazine assembly 2 is released to allow the nail magazine assembly 2 to fire.

[0089] After receiving the unlock command when the timing duration is less than the set duration, the unlock command is received again and the timing duration is still less than the set duration when the unlock command is received again, indicating that the doctor sent the unlock command twice in succession when the duration is less than the set duration. At this time, the instrument executes the unlock command to unlock the nail magazine assembly 2, so that the nail magazine assembly 2 can be fired.

[0090] Since the specific conditions of different patients vary greatly, doctors need to reasonably select the specific timing of the firing operation according to the specific conditions of each patient. Although in most cases, it is more appropriate to release the lock of the nail magazine assembly 2 after the set time to perform the firing operation, in a few cases, it may be necessary to perform the firing operation within the set time.

[0091] Therefore, the above solution of unlocking the staple cartridge assembly 2 by two unlocking instructions within the set time can meet the above needs of doctors, and is convenient for doctors to reasonably choose the specific time to unlock the staple cartridge assembly 2 and fire according to actual conditions, thereby improving the flexibility of product use, expanding the scope of product use scenarios, and improving the user experience. Of course, the staple cartridge assembly 2 can also be unlocked by three or more unlocking instructions within the set time.

[0092] In an exemplary embodiment, determining whether to unlock the staple cartridge assembly 2 according to the timing duration and the unlocking instruction further includes:

[0093] After receiving the unlocking instruction when the timing time is less than the set time, the nail magazine assembly 2 is unlocked until the timing time is greater than or equal to the set time so that the nail magazine assembly 2 can be fired.

[0094] After receiving the unlocking instruction when the timing time is less than the set time, the doctor does not send the unlocking instruction again until the timing time is greater than or equal to the set time, indicating that the last unlocking instruction may be a mistake by the doctor. When the timing time reaches the set time, the appropriate squeezing time has come, and the lock of the nail magazine assembly 2 is automatically released, so that the nail magazine assembly 2 can be fired. In this way, the doctor does not need to send the unlocking instruction again, and can directly operate the instrument to fire, which improves the operation convenience of the product.

[0095] In an exemplary embodiment, the set time length is in the range of 10s to 15s.

[0096] According to clinical surgical experience, in order to ensure that the compression time of the tissue is controlled, the optimal compression time is generally 10s to 15s, and the firing operation has a relatively ideal effect. Therefore, the setting time can be limited to the range of 10s to 15s, such as 10s, 11s, 12s, 13s, 14s, 15s, etc.

[0097] Of course, the set duration is not limited to the above range and can be adjusted as needed.

[0098] In one example, the duration is set to 10 seconds.

[0099] In another example, the duration is set to 15 seconds.

[0100] In an exemplary embodiment, the control method further includes:

[0101] When the nail magazine assembly 2 is unlocked, a first prompt signal is issued to prompt the nail magazine assembly 2 to be unlocked;

[0102] When the nail magazine assembly 2 is locked, a second prompt signal is sent to prompt that the nail magazine assembly 2 has not been unlocked.

[0103] When the nail magazine assembly 2 is unlocked, a first prompt signal is issued to clearly remind the doctor that the nail magazine assembly 2 has been unlocked and the firing operation can be performed, so that the doctor can obtain this information in time, thereby improving the convenience of using the product.

[0104] Similarly, when the unlocking instruction is received before the set time is reached and the nail magazine assembly 2 is locked, a second prompt signal is sent to clearly remind the doctor that the nail magazine assembly 2 has not been unlocked, and indirectly remind the doctor to check whether he has made an erroneous operation. If it is an erroneous operation, he can wait for some time before firing; if it is not an erroneous operation, he can send the unlocking instruction again to confirm that he really needs to fire in advance.

[0105] In an exemplary embodiment, the first prompt signal includes: displaying a flashing forward arrow, which is consistent with the firing direction, so as to facilitate the doctor's understanding. The second prompt signal includes: displaying a flashing timing duration.

[0106] The flashing frequency of the forward arrow and / or the timing duration can also be adjusted as needed. For example, when the duration is set to 10 seconds, it flashes once per second; when the duration is set to 15 seconds, it flashes twice per second.

[0107] Of course, the first prompt signal and the second prompt signal are not limited to the above scheme, and other prompting methods may also be used, such as voice, music, picture, video, etc.

[0108] In an exemplary embodiment, the control method further includes:

[0109] After unlocking the nail magazine assembly 2, a firing instruction is received, the nail magazine assembly 2 is controlled to fire and a third prompt signal is issued;

[0110] After the nail magazine assembly 2 is controlled to complete firing, a fourth prompt signal is issued and the nail magazine assembly 2 is controlled to automatically retract to the initial position.

[0111] After unlocking the nail magazine assembly 2, a firing command is received, a firing operation is executed to control the nail magazine assembly 2 to fire, and a third prompt signal is issued. The third prompt signal can prompt that the instrument is currently in a firing state, so that the doctor can know the firing state of the instrument in time.

[0112] When the firing operation is completed, the control cartridge assembly 2 automatically returns to the initial position, so that the cartridge assembly 2 can be replaced for the next firing. At this time, the fourth prompt signal is sent, so that the doctor can know in time that the instrument has completed the current firing and can replace the cartridge assembly 2 in time for the next firing.

[0113] In an exemplary embodiment, the third prompt signal includes: displaying a forward arrow that is always on, and the forward arrow changes from a flashing state to a always on state, indicating that it is in a firing state. The fourth prompt signal includes: displaying a backward arrow that is always on, indicating that the backward movement is completed, which is consistent with the backward movement direction, and is easy for doctors to understand.

[0114] Of course, the third prompt signal and the fourth prompt signal are not limited to the above schemes, and other prompting methods may also be used, such as voice, music, picture, video, etc.

[0115] In an exemplary embodiment, the control method further includes:

[0116] When the current exceeds the set threshold value during the firing process of the nail magazine assembly 2, a fifth prompt signal is issued to prompt the input of an electric retraction command;

[0117] When the electric retraction instruction is received but the electric retraction of the nail magazine assembly 2 fails, a sixth prompt signal is sent to prompt the manual retraction of the nail magazine assembly 2.

[0118] When the firing operation is not completed but the instrument cannot continue to fire forward, the current in the circuit may be too large due to excessive cutting force, and the system will automatically turn on the protection mode. Therefore, when the current exceeds the set threshold during the firing process of the staple cartridge assembly 2, the fifth prompt signal is issued to facilitate the user to promptly know the state, so as to promptly input the electric retraction command to retract the staple cartridge assembly 2 in time.

[0119] When the electric retraction command is received but the electric retraction of the nail magazine assembly 2 fails, it indicates that the instrument has failed. At this time, the sixth prompt signal is issued to facilitate the user to promptly know the status and to manually operate the operating handle 116 in time to retract the nail magazine assembly 2 and minimize the harm to the patient.

[0120] In an exemplary embodiment, the fifth prompt signal includes: displaying a first error code. The sixth prompt signal includes: displaying a second error code.

[0121] Of course, the fifth prompt signal and the sixth prompt signal are not limited to the above schemes, and other prompting methods may also be used, such as voice, music, picture, video, etc.

[0122] In an exemplary embodiment, the control method further includes:

[0123] When the staple cartridge assembly 2 is electrically retracted and opened, a seventh prompt signal is issued to prompt completion of use.

[0124] Regardless of whether it retracts automatically after firing is completed, or electric retraction is achieved by inputting an electric retraction command, when the nail magazine assembly 2 is electrically retracted and opened, a seventh prompt signal is issued to prompt that the use is completed, so that the user can promptly know the status of the retraction completion.

[0125] In an exemplary embodiment, the seventh prompt signal is: the back arrow is off.

[0126] Of course, the seventh prompt signal is not limited to the above scheme, and other prompting methods may also be used, such as voice, music, picture, video, etc.

[0127] In an exemplary embodiment, Figure 2 As shown, before step S102, the control method further includes:

[0128] Step S100: after power-on, perform a system self-check to confirm whether the electric laparoscopic stapler is normal;

[0129] Step S106: When it is confirmed that the electric laparoscopic stapler is abnormal, an eighth prompt signal is issued to prompt the replacement of the electric laparoscopic stapler.

[0130] After power is turned on, the system will first perform a self-check to confirm whether the electric laparoscopic stapler is normal, so that the doctor can clearly know whether the instrument is normal or not. If the electric laparoscopic stapler is confirmed to be normal, the doctor can use it normally. If the electric laparoscopic stapler is confirmed to be abnormal, the eighth prompt signal will be issued to remind the doctor of the abnormal state of the instrument, so that the doctor can replace the new electric laparoscopic stapler in time to avoid the use of abnormal instruments during surgery, which may cause inconvenience or other adverse effects due to the need to temporarily replace the instrument.

[0131] This solution enables the electric laparoscopic stapler to have a self-checking function. Before starting to use the instrument, it will automatically detect whether the switches of each part are in the initial state, or before the instrument completes a cut and replaces the stapler assembly 2 for another cut, it will determine and detect whether each switch is in the initial position state. If so, the instrument can be used normally; if not, an error reminder will be issued.

[0132] In an exemplary embodiment, the eighth prompt signal is: displaying the second error code or displaying a black screen. In this way, the device has only two error codes, which is convenient for doctors to simply distinguish the fault status of the device so as to make the correct response. When the first error code (such as E00) is displayed, it indicates that the device has only started the overcurrent protection mode and can still be used normally. When the second error code (such as E11) is displayed, it indicates that the device is faulty and cannot be used normally, and a new device needs to be replaced.

[0133] Of course, the eighth prompt signal is not limited to the above scheme, and other prompting methods may also be used, such as voice, music, picture, video, etc.

[0134] In an exemplary embodiment, between step S102 and step S104, the control method further includes at least one of the following steps:

[0135] After the nail magazine assembly 2 is closed, the doctor can repeat the opening and closing process as needed. In this process, only the last closure will start to compress the tissue. Therefore, the timing duration of the last start and the unlocking instruction will be used as the basis for judging whether to release the lock of the nail magazine assembly 2.

[0136] In an exemplary embodiment, the control method further includes:

[0137] After power-on, the remaining power of the electric laparoscopic stapler is displayed.

[0138] Since electric laparoscopic staplers are usually powered by batteries, the remaining power is displayed after power is turned on, so that doctors can know the power status in time and replace the battery or the instrument in time.

[0139] like Figure 3 As shown, an embodiment of the present application also provides a control device 3 for an electric laparoscopic stapler, including a processor 31 and a memory 32 storing a computer program. When the processor 31 executes the computer program, the steps of any control method in the above embodiments are implemented, and thus all the above-mentioned beneficial effects are obtained, which will not be repeated here.

[0140] The processor 31 may be an integrated circuit chip with signal processing capabilities. The above-mentioned processor 31 may be a general-purpose processor 31, including a central processing unit 31 (CPU), a network processor 31 (NP), etc.; it may also be a digital signal processor 31 (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components.

[0141] The embodiment of the present application also provides an electric laparoscopic stapler, including the control device 3 of the above embodiment, and thus has all the above beneficial effects, which will not be repeated here.

[0142] The embodiment of the present application also provides an electric laparoscopic stapler, comprising: a stapler body 1 , a stapler magazine assembly 2 and a control device 3 .

[0143] The stapler assembly 2 is movably connected to the stapler body 1 .

[0144] The control device 3 is electrically connected to the stapler body 1. The control device 3 includes a timing module and a control module. The timing module is configured to start timing when it is confirmed that the staple cartridge assembly 2 is assembled and closed after power is turned on. The control module is configured to determine whether to unlock the staple cartridge assembly 2 according to the timing duration and the unlocking instruction.

[0145] The electric laparoscopic stapler provided in the embodiment of the present application can start timing after power is turned on and it is confirmed that the staple magazine assembly 2 is assembled and closed, and determine whether to release the lock of the staple magazine assembly 2 based on the timing duration and the unlocking instruction. This makes it convenient for the doctor to perform the firing operation at the appropriate time, which helps prevent the doctor from accidentally firing the instrument due to misoperation of the instrument, thereby improving the convenience and safety of using the electric laparoscopic stapler.

[0146] In an exemplary embodiment, the control device 3 further includes: a display component 13, such as Figure 4 The display component 13 is electrically connected to the control module and is used to display corresponding prompt signals according to the working status of the electric laparoscopic stapler.

The display screen has a first display area 131, such as Fig.11 , Fig.12 and Fig.13 As shown, the first display area 131 is configured to display the timing duration, such as Fig.12 This makes it easy for the doctor to unlock the nail magazine assembly 2 at an appropriate time to perform a firing operation, which is beneficial to improving the convenience and safety of the product.

[0149] In an exemplary embodiment, the display screen further includes a second display area 132, such as Fig.12 The second display area 132 is configured to display the working status of the staple cartridge assembly 2. This facilitates the doctor to know the working status of the staple cartridge assembly 2 in a timely manner, providing convenience for the doctor.

[0150] In an exemplary embodiment, the second display area 132 includes a forward arrow display area and a backward arrow display area. Fig.12 As shown. The forward arrow may indicate that the staple cartridge assembly 2 has been unlocked and is ready to fire or is firing. The backward arrow may indicate that the staple cartridge assembly 2 is retreating or has completed retreating. The prompt mark of this solution is simple, clear, and easy to understand.

[0151] In an exemplary embodiment, the second display area 132 is located on a side of the first display area 131 close to the staple cartridge assembly 2. Fig.12 As shown. In this way, the second display area 132 is close to the nail magazine assembly 2, corresponding to the position of the nail magazine assembly 2, and the layout is more reasonable. Of course, the second display area 132 can also be set at other positions.

[0152] In an exemplary embodiment, Fig.12 As shown, there is a first reserved display area 134 between the end of the display screen close to the nail magazine assembly 2 and the second display area 132, which has a relatively compact layout and can provide a reserved display area for subsequent upgrades and improvements of the displayed content. Of course, the first reserved display area 134 can also be cancelled.

[0153] In an exemplary embodiment, the stapler body 1 includes a battery assembly 14, such as Figure 4 The display screen also has a third display area 133, such as Fig.11 , Fig.12 and Fig.13 The third display area 133 is configured to display the remaining power of the battery assembly 14, so that the doctor can know the remaining power of the battery assembly 14 in time and avoid danger caused by insufficient power during surgery.

[0154] In an exemplary embodiment, the third display area 133 is located on a side of the first display area 131 away from the staple cartridge assembly 2. Fig.11 , Fig.12 and Fig.13 As shown. In this way, the third display area 133 is close to the battery assembly 14, corresponding to the position of the battery assembly 14, and the layout is more reasonable. Of course, the third display area 133 can also be set at other positions.

[0155] In an exemplary embodiment, a second reserved display area 135 is provided between the end of the display screen away from the nail magazine assembly 2 and the third display area 133. Fig.12 As shown, the layout is relatively compact, and a reserved display area can be provided for subsequent upgrade and improvement of the displayed content. Of course, the second reserved display area 135 can also be cancelled.

[0156] In an exemplary embodiment, the first display area 131 includes a plurality of 8-shaped display areas, such as Fig.12 The first display area 131 is also configured to display an error code, such as Fig.11 and Fig.13 In this way, the first display area 131 can display both the timing duration and the error code, thereby improving the integration of the display component 13 and simplifying the product structure.

[0157] In an exemplary embodiment, the stapler body 1 includes a closing trigger 111, such as Figure 4 The closing trigger 111 is annular, and the inner wall surface of the closing trigger 111 is provided with a matching surface 1111 for matching with a finger, as shown in FIG. Figure 5 shown.

[0158] The closing trigger 111 adopts a closed ring design to prevent the doctor from slipping between the closing trigger 111 and the hand due to repeated closing or opening of the jaws 121 during use. The closed ring handle design can effectively avoid slipping, meet the needs of ergonomics, and make the operation safer, more convenient and quicker. The inner wall surface of the closing trigger 111 is provided with a matching surface 1111 for adapting to the finger, so that the doctor's finger can cooperate with the matching surface 1111, further avoiding slipping.

[0159] In one example, the mating surface 1111 is wavy, so that fingers can fit with the concave and convex mating surface 1111, effectively avoiding slipping.

[0160] In one example, the mating surface 1111 is set to a rough surface, which can increase the friction between the finger and the mating surface 1111, thereby avoiding slipping.

[0161] The rough surface may be provided as a frosted structure or a plurality of stripes that are parallel to or interlaced with each other.

[0162] In an exemplary embodiment, the control module is configured such that: when the timing duration is greater than or equal to the set duration, an unlocking instruction is received, and the lock on the nail magazine assembly 2 is released to allow the nail magazine assembly 2 to be fired; when the timing duration is less than the set duration, an unlocking instruction is received, and the nail magazine assembly 2 remains locked to limit the firing of the nail magazine assembly 2.

[0163] In an exemplary embodiment, the control module is further configured to: after receiving an unlock command when the timing duration is less than the set duration, receiving an unlock command again and the timing duration is still less than the set duration when the unlock command is received again, release the lock on the nail magazine assembly 2 to allow the nail magazine assembly 2 to fire.

[0164] In an exemplary embodiment, the control module is further configured to: after receiving an unlocking instruction when the timing duration is less than the set duration, unlock the nail magazine assembly 2 until the timing duration is greater than or equal to the set duration to allow the nail magazine assembly 2 to fire.

[0165] In an exemplary embodiment, the set time length is in the range of 10s to 15s.

[0166] In an exemplary embodiment, the control module is further configured to: when the nail magazine assembly 2 is unlocked, the control display assembly 13 sends a first prompt signal to prompt that the nail magazine assembly 2 is unlocked; when the nail magazine assembly 2 is kept locked, the control display assembly 13 sends a second prompt signal to prompt that the nail magazine assembly 2 has not been unlocked.

[0167] In an exemplary embodiment, the first prompt signal includes: displaying a flashing forward arrow. The second prompt signal includes: displaying a flashing timing duration.

[0168] In an exemplary embodiment, the control module is further configured to: after unlocking the nail magazine assembly 2, receive a firing command, control the nail magazine assembly 2 to fire and control the display assembly 13 to send a third prompt signal; after controlling the nail magazine assembly 2 to complete firing, control the display assembly 13 to send a fourth prompt signal and control the nail magazine assembly 2 to automatically retract to the initial position.

[0169] In an exemplary embodiment, the third prompt signal includes: displaying a forward arrow that is always on; and the fourth prompt signal includes: displaying a backward arrow that is always on.

[0170] In an exemplary embodiment, the control module is also configured to: when the current exceeds the set threshold during the firing process of the nail magazine assembly 2, the control display assembly 13 sends a fifth prompt signal to prompt the input of an electric retraction command; when the electric retraction command is received but the electric retraction of the nail magazine assembly 2 fails, the control display assembly 13 sends a sixth prompt signal to prompt the manual retraction of the nail magazine assembly 2.

[0171] In an exemplary embodiment, the fifth prompt signal includes: displaying a first error code, such as Fig.13 The sixth prompt signal includes: displaying the second error code, such as Fig.11 shown.

[0172] In an exemplary embodiment, the control module is further configured to: when the nail magazine assembly 2 is electrically retracted and opened, control the display assembly 13 to send a seventh prompt signal to prompt completion of use.

[0173] In an exemplary embodiment, the seventh prompt signal is: the back arrow is off.

[0174] In an exemplary embodiment, the control module is further configured to: after power-on, when it is confirmed that the stapler assembly 2 is assembled and closed, before starting the timing step, perform a system self-check after power-on to confirm whether the electric laparoscopic stapler is normal; when it is confirmed that the electric laparoscopic stapler has an abnormality, control the display assembly 13 to send an eighth prompt signal to prompt the replacement of the electric laparoscopic stapler.

[0175] In an exemplary embodiment, the eighth prompt signal is: displaying a second error code or displaying a black screen.

[0176] In an exemplary embodiment, the control module is further configured to: after power-on, when it is confirmed that the nail magazine assembly 2 is assembled and closed, between the step of starting timing and the step of determining whether to release the lock of the nail magazine assembly 2 based on the timing duration and the unlocking instruction, the timing module is controlled to stop timing and reset when it is detected that the nail magazine assembly 2 is open, and restart timing when it is detected that the nail magazine assembly 2 is closed again; in the step of determining whether to release the lock of the nail magazine assembly 2 based on the timing duration and the unlocking instruction, the timing duration is the timing duration of the last timing process in the above step.

[0177] In an exemplary embodiment, the control module is further configured to: also include: after power is turned on, control the display component 13 to display the remaining power of the electric laparoscopic stapler.

[0178] The beneficial effects of the above embodiments can be understood by referring to the description of the above control method embodiment part, which will not be repeated here.

[0179] The working principle of the electric laparoscopic stapler in the above embodiment is introduced below with reference to the accompanying drawings.

[0180] 1) Equipment self-check function:

[0181] Before using the device, first install the staple cartridge assembly 2, and then install the battery assembly 14. After the battery assembly 14 is installed, the circuit system in the device is powered on. The system automatically detects whether the relative positions of the switches at various locations on the device are in the initial positions. When the detection confirms that the switches at various locations are in the initial positions, the device can be used normally. When the device display shows error E00 (i.e., the second error code is displayed, such as Fig.11 When the instrument is in the same position as the original position shown in the figure, it indicates that the initial position of the instrument has changed. At this time, the electronic control part of the instrument fails and a new instrument should be replaced.

[0182] 2) Closing and opening of the jaws 121:

[0183] The closing / opening movement of the closing trigger 111 corresponds to the closing / opening movement of the jaw 121. In other words, when the closing trigger 111 is closed, the jaw 121 is closed, and the nail magazine assembly 2 is closed. Figure 8 When the trigger 111 is closed and opened, the jaws 121 are opened and the staple cartridge assembly 2 is opened. Figure 7 shown.

[0184] For ease of operation, when the closing trigger 111 is open, the firing button 113 is hidden inside the body. When the closing trigger 111 is closed, the firing button 113 is exposed from the handle of the body. This can effectively avoid the firing button 113 and the closing trigger 111 appearing at the same time, which may cause misoperation, such as Figure 7 and Figure 8 shown.

[0185] 3) Swinging of the jaws 121:

[0186] When the jaws 121 need to bend to a certain angle to clamp the tissue, the jaws 121 can be swung left and right by simply twisting the knob 122 on the rotating head (such as Fig. 9 and Fig.10 shown).

[0187] 4) Confirmation and firing:

[0188] When the closing trigger 111 is closed, that is, the jaws 121 and the nail magazine assembly 2 are closed, the display screen timing starts.

[0189] When the timing duration is ≥ 10s (or 15s), the confirmation button 112 is pressed, and the forward arrow on the display screen starts flashing (i.e., the first prompt signal is displayed), indicating that the nail magazine assembly 2 has been unlocked. At this time, the firing button 113 is triggered to realize the electric firing function.

[0190] When the timing duration is less than 10s (or 15s), the confirmation button 112 is pressed, and the second count on the display screen starts flashing (i.e., the second prompt signal is displayed). At this time, the firing is still invalid, indicating that the nail magazine assembly 2 is kept locked. If the confirmation button 112 is pressed again within the timing duration of less than 10s (or 15s), the forward arrow on the display screen starts flashing (i.e., the first prompt signal is displayed), indicating that the nail magazine assembly 2 is unlocked. At this time, the firing button 113 is triggered to realize the electric firing function.

[0191] When the timing duration is less than 10s (or 15s), the confirmation button 112 is pressed, and the second count on the display screen starts flashing (i.e., the second prompt signal is displayed). At this time, the firing is invalid, indicating that the nail magazine assembly 2 is kept locked. If the timing duration is ≥ 10s (or 15s), there is no need to press the confirmation button 112, and the forward arrow on the display screen starts flashing (i.e., the first prompt signal is displayed), indicating that the nail magazine assembly 2 has been unlocked. At this time, the firing button 113 is triggered to realize the electric firing function.

[0192] The confirmation button 112 is set to ensure that the compression time of the tissue is controlled. Generally, the best compression time is 10s-15s before the firing 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 (such as Figure 8 and Fig.12 shown).

[0193] 5) Electric / mechanical retraction:

[0194] When the instrument is fired, it will automatically cut back to the firing start point. At this time, the reset button 115 is pressed, and the jaws 121 are automatically opened, completing the use of the instrument.

[0195] When the firing of the instrument is not completed, but the instrument cannot continue to fire forward, it may be because the cutting force is too large, resulting in excessive current in the circuit, and the system automatically turns on the protection mode, that is, the display screen displays error E11 (that is, displays the first error code, such as Fig.13 At this time, the doctor needs to press the reverse button 114 to make it electrically retract until the electrical retraction is completed, and then open the jaws 121 to complete the use.

[0196] When the electric retraction of the instrument fails, the display screen may be black due to power supply problems or display an error of E00 (i.e., displaying the second error code), and manual retraction is required (disassembling the display assembly 13 and moving the operating handle 116), and then opening the jaws 121 to complete the use, such as Fig.14 and Fig.15 shown.

[0197] 6) Equipment use and electronic control principle (such as Fig.16 and Fig.17 shown):

[0198] The process of using the device is as follows: installing the nail magazine assembly 2 - installing the battery assembly 14 - closing / opening the trigger - pressing the confirmation button 112 - pressing the firing button 113 - electric firing - electric retraction - pressing the reset button 115 - repeating the installation of the new nail magazine assembly 2.

[0199] Electrical control part: Various key switches (close / open / reverse, etc.) are subject to mechanical limit and electrical control, and each switch must be pressed in sequence according to the operation process of the instrument. During the triggering of the switch, the signal recognition of the processor 31 system determines whether the next step can be performed. (Such as the forward and reverse rotation of the motor, the status reminder of the display screen, etc.). This process ensures that the mechanical part and the electrical control part jointly provide protection for the safety of the instrument during operation.

[0200] To sum up, the control method, control device and electric laparoscopic stapler for an electric laparoscopic stapler provided in the embodiments of the present application have simple structure, low price, high product safety and stable product performance. It is an effective and cost-effective product that is conducive to improving the market competitiveness of domestic electric laparoscopic staplers.
