[0054] In order to better describe the electric stapler clamping and cutting state detection system, method and storage medium of the embodiment of the present invention, the structure of the clamping part of the electric stapler is briefly described here, and reference is made to Figures 1 to 5 A stapler seat 210 is provided at the front end of the electric stapler, and a stapler forming groove 211 is provided on the stapler seat 210. A rotatable rotating clamp 230 is also provided at the front end of the electric stapler. A stapler magazine 220 is provided on the side of the rotating clamp 230 close to the stapler seat 210, and the stapler magazine 220 is used to place staples.

It should be noted that the above structure is only for the purpose of better describing the embodiment of the present invention and should not be used as a limitation on the protection scope of the embodiment of the present invention.

[0056] See also Figure 6 As shown, Figure 6 1 is a system diagram of a clamping and cutting state detection system for an electric stapler provided by an embodiment of the present invention, the clamping and cutting state detection system for an electric stapler comprising: a plurality of clamping thickness detection units 110, a control unit 120 and a display unit 130;

[0057] A plurality of clamping thickness detection units 110 are disposed on the anvil 210 of the electric stapler and are located on a side surface close to the stapler magazine 220 of the electric stapler. Each clamping thickness detection unit 110 is disposed outside the staple forming groove 211 on the anvil 210.

[0058] The cutting resistance detection unit 140 is disposed on the cutting head 240 of the electric stapler and is located on the side of the cutting head 240;

[0059] The control unit 120 is connected to multiple clamping thickness detection units 110 and cutting resistance detection units 140 respectively, and is used to adjust the clamping state and cutting state of the electric stapler according to the tissue thickness data detected by the multiple clamping thickness detection units 110 and the cutting resistance data detected by the cutting resistance detection unit 140.

[0060] like Figures 1 to 6As shown, a plurality of clamping thickness detection units 110 are provided on the lower surface of the staple support 210, and each clamping thickness detection unit 110 is provided on the periphery of the staple forming groove 211, and cannot block the staple forming groove 211, thereby ensuring that the staple forming groove 211 can normally form the staples during the stapling operation. The plurality of clamping thickness detection units 110 need to be dispersedly arranged so that the thickness at different positions can be detected, avoiding erroneous judgment caused by erroneous detection results of a single clamping thickness detection unit 110. A cutting resistance detection unit 140 is provided on the side of the blade of the cutter head 240. In actual setting, the cutting resistance detection unit 140 needs to be set as far as possible to the rear end of the blade to avoid affecting the cutting function of the cutter head 240.

[0061] In actual operation, if the tissue thickness data detected by the clamping thickness detection unit 110 exceeds the preset threshold value of tissue thickness or the cutting resistance data detected by the cutting resistance detection unit 140 exceeds the preset threshold value of cutting resistance, it is necessary to stop the electric stapler in time to avoid damage to the tissue.

[0062] The clamping and cutting state detection system of the electric stapler in the embodiment of the present invention can detect tissue thickness data by setting a plurality of clamping thickness detection units 110 on the stapler seat 210, and the clamping thickness detection unit 110 is set outside the stapler forming groove 211, and will not interfere with the suturing process of the electric stapler. The cutting resistance detection unit 140 is set on the side of the cutter head 240 to detect the cutting resistance, and the cutting resistance detection unit 140 is set on the side of the cutter head 240 to effectively avoid the impact on the cutting of the cutter head 240. Compared with the traditional clamping pressure display method, the clamping and cutting state detection system of the electric stapler in the embodiment of the present invention has the ability to detect the clamping thickness and cutting resistance in real time, and can realize automatic protection according to the detected tissue thickness data and cutting resistance data, which greatly reduces the requirements for operators and is suitable for large-scale promotion and use.

[0063] refer to Figure 1 , Figure 6 In some embodiments, the electric stapler clamping and cutting state detection system also includes a display unit 130, which is connected to the control unit 120; the control unit 120 is used to determine the current working state based on the tissue thickness data detected by the multiple clamping thickness detection units 110 and the cutting resistance data detected by the cutting resistance detection unit 140, and the display unit 130 is used to display the current working state.

[0064] The display unit 130 can be used to display the working status of the electric stapler in real time, so that the operator can view the working status of the electric stapler in real time. In some embodiments, because tissue thickness detection and cutting resistance detection are analog output quantities, tissue thickness data and cutting resistance data can be viewed in real time through the display unit 130, thereby defensively determining whether a problem is about to occur.

[0065] refer to Figure 4 , Figure 5 In some embodiments, there are two cutting resistance detection units 140, one on each side of the cutter head 240. By providing one cutting resistance detection unit 140 on each side of the cutter head 240, the current cutting resistance data can be determined more accurately, and the detection error caused by a single cutting resistance detection unit 140 can be avoided. At the same time, the two cutting resistance detection units 140 can also serve as emergency backups for each other, and avoid the situation where a single cutting resistance detection unit 140 fails and cannot be used directly.

[0066] In some embodiments, there are two clamping thickness detection units 110, and the two clamping thickness detection units 110 are respectively arranged at the front side and the rear side of the anvil 210. The clamping thickness detection unit 110 can be arranged one at the front and the back of the anvil 210, for example, Figure 2 In the two front and rear dotted boxes shown, the front and rear clamping thicknesses of the dowel seat 210 can be detected separately, thereby avoiding the errors caused by the detection of a single clamping thickness detection unit 110.

[0067] refer to Figure 2 , Figure 3 In some embodiments, there are four clamping thickness detection units 110, two clamping thickness detection units 110 are arranged on the front side of the anvil 210, and two clamping thickness detection units 110 are arranged on the rear side of the anvil 210. Two clamping thickness detection units 110 are arranged on the front and rear sides of the anvil 210, respectively, and this arrangement can better detect the clamping thickness.

[0068] In some embodiments, the two clamping thickness detection units 110 disposed on the front side of the anvil 210 are symmetrically distributed on the left and right sides of the anvil 210, and the two clamping thickness detection units 110 disposed on the rear side of the anvil 210 are symmetrically distributed on the left and right sides of the anvil 210. Figure 2 , Figure 3 The two clamping thickness detection units 110 on the front and rear sides are both distributed in a left-right symmetrical manner, which can further improve the accuracy of thickness detection. At the same time, the use of four clamping thickness detection units 110 will not cause excessive burden on data processing.

[0069] In some embodiments, the display unit 130 includes an LED display unit connected to the control unit 120. The display unit 130 can directly use an LED display unit. For example, different colors of LED indicator lights can be used to indicate the current working state. The first color indicator light indicates that the clamping thickness is normal, the second color indicator light indicates that the clamping thickness is abnormal, the third color indicator light indicates that the cutting resistance is normal, and the fourth color indicator light indicates that the cutting resistance is abnormal. The four color indicator lights can use different colors, or a combination of color and flashing frequency can be used. It should be noted that the current working state can be divided more accurately according to actual needs. At this time, the number, color, and flashing frequency of the indicator lights can also be appropriately adjusted according to needs.

[0070] like Figure 1 As shown, in some embodiments, the display unit 130 is disposed on the top of the gun body of the electric stapler. The display unit 130 disposed on the top can be more convenient for the operator to observe.

[0071] In some embodiments, the control unit 120 is an ASIC control system carried by the electric stapler itself. The control unit 120 can directly use the ASIC control system carried by the electric stapler, which can effectively save costs and facilitate the control of the volume of the electric stapler without adding an additional controller.

[0072] In some embodiments, the clamping thickness detection unit 110 uses a clamping pressure sensor or a clamping pressure detection switch. The clamping pressure sensor can realize continuous detection of the clamping pressure, and the control unit 120 can obtain these continuous clamping pressure data, and then use these clamping pressure data to obtain tissue thickness data. Here is a brief description of how to use the clamping pressure data to obtain the clamping thickness data. First of all, it can be understood that the rotation of the rotating clamping member 230 is driven by the motor inside the electric stapler using the transmission structure. Therefore, the rotation angle of the rotating clamping member 230 can be determined by the number of rotations and the rotation position of the motor. When it is determined through the clamping pressure data that the clamping of the tissue has been completed, the action of the rotating clamping member 230 will be stopped. At this time, the rotation angle of the rotating clamping member 230 can be determined according to the number of rotations and the rotation position of the motor. The thickness of the currently clamped tissue can be determined by the installation position of the pressure sensor on the nail seat 210, and multiple thicknesses can be determined by using multiple pressure sensors. Subsequently, the average value calculation or weighted average calculation is performed to obtain tissue thickness data that is as close to the actual thickness of the tissue as possible. The current clamping state can be determined by using the tissue thickness data and the preset threshold value of the tissue thickness. In addition, in actual operation, the pressure sensor will not be completely parallel to the tissue during clamping, and the greater the thickness of the tissue, the greater the angle formed. Therefore, a large amount of clamping pressure data can be used to construct the correlation between clamping pressure and tissue thickness. Generally, the thinner the tissue thickness, the greater the pressure change in the same time, so the tissue thickness can be determined by the corresponding relationship between the clamping pressure change speed and the tissue thickness. In addition, the tissue thickness data calculated by the control unit 120 can be displayed by the display unit 130. It should also be noted that in extreme cases, a unified pressure preset threshold value can be directly set to replace the tissue thickness preset threshold value, that is, as long as the clamping pressure monitored by the pressure sensor exceeds the pressure preset threshold value, the current tissue thickness is assumed to be too thick, and the electric stapler can be directly stopped. In this application mode, a clamping pressure detection switch can be used as a substitute. The clamping pressure detection switch can directly change the output state when the preset pressure value is reached. The control unit 120 determines that the clamping thickness is abnormal according to the current clamping state and controls the electric stapler to stop working.

[0073] It should also be noted that when using the clamping pressure sensor for detection, if there is a clamping pressure sensor that cannot detect pressure data, the clamping pressure sensor may be faulty, and an early warning will be issued through the display unit 130 to prompt the operator to perform detection and eliminate the fault in time. In addition, when performing the mean calculation to determine the displayed clamping pressure, the data detected by the clamping pressure sensor will also be eliminated to avoid interference of single abnormal data in pressure detection.

[0074] In some embodiments, the cutting resistance detection unit 140 uses a cutting pressure sensor or a cutting pressure detection switch. The pressure sensor is arranged on the side of the cutter head 240, and can detect the pressure from the front when the cutter head 240 is advanced. The pressure data can intuitively reflect the current cutting resistance. When pressure sensors are arranged on both sides of the cutter head 240, two pressure data can be obtained by detecting the cutting resistance at both ends of the cutter head 240, and then the mean value can be obtained by mean calculation. The mean value can better characterize the current cutting resistance, that is, the mean value is converted using a position conversion coefficient (the position conversion coefficient needs to be obtained by considering the measurement deviation between the side and front of the cutter head 240). The cutting resistance data can be obtained. When the detected cutting resistance data is greater than the preset threshold value of the cutting resistance, the electric stapler is controlled to stop the action to avoid damage to the tissue. In addition, the cutting resistance data calculated by the control unit 120 can be displayed by the display unit 130. It should be noted that in some cases, it is not necessary to continuously detect the cutting resistance data. It is only necessary to determine whether the current cutting resistance data exceeds the preset threshold value of the cutting resistance. At this time, the pressure detection switch can be used directly for detection. When the cutting resistance is greater than the preset threshold value of the cutting resistance, that is, when the pressure detection switch detects that the pressure is greater than the preset pressure value (this value corresponds to the preset threshold value of the cutting resistance, that is, the preset threshold value of the cutting resistance is obtained by converting the preset pressure value through the position conversion coefficient), the output state will be directly changed, and the control unit 120 will directly stop the action of the electric stapler.

[0075] It should also be noted that when using cutting pressure sensors for detection, if one of the cutting pressure sensors cannot detect pressure data, the cutting pressure sensor may be faulty, and an early warning will be issued through the display unit 130 to prompt the operator to perform detection and eliminate the fault in time.

[0076] In some embodiments, the electric stapler clamping and cutting state detection system further includes a digital display unit 150 connected to the control, and the cutting resistance data and tissue thickness data can be displayed separately by the digital display unit 150. In this structural form, the display unit can be an LED display unit, which is only used as a state indicator. Figure 1 As shown, in some embodiments, the digital display unit 150 is disposed on the side of the gun body.

[0077] refer to Figure 7 , Figure 7 A flowchart of a method for detecting the clamping and cutting state of an electric stapler provided in an embodiment of the present invention, wherein the method for detecting the clamping and cutting state of an electric stapler comprises the following steps:

[0078] Acquire tissue thickness data collected by a plurality of clamping thickness detection units 110;

[0079] Acquire cutting resistance data collected by the cutting resistance detection unit 140;

[0080] The clamping and cutting states of the electric stapler are adjusted according to the multiple tissue thickness data and the cutting resistance data, so that the electric stapler stops the stapling operation when the tissue thickness data exceeds the preset tissue thickness threshold value and / or the cutting resistance data exceeds the preset cutting resistance threshold value.

[0081] like Figures 1 to 7 As shown, a plurality of clamping thickness detection units 110 are provided on the lower surface of the staple support 210, and each clamping thickness detection unit 110 is provided on the periphery of the staple forming groove 211, and cannot block the staple forming groove 211, thereby ensuring that the staple forming groove 211 can normally form the staples during the stapling operation. The plurality of clamping thickness detection units 110 need to be dispersedly arranged so that the thickness at different positions can be detected, avoiding erroneous judgment caused by erroneous detection results of a single clamping thickness detection unit 110. A cutting resistance detection unit 140 is provided on the side of the blade of the cutter head 240. In actual setting, the cutting resistance detection unit 140 needs to be set as far as possible to the rear end of the blade to avoid affecting the cutting function of the cutter head 240.

[0082] In actual operation, if the tissue thickness data detected by the clamping thickness detection unit 110 exceeds the preset threshold value of tissue thickness or the cutting resistance data detected by the cutting resistance detection unit 140 exceeds the preset threshold value of cutting resistance, it is necessary to stop the electric stapler in time to avoid damage to the tissue.

[0083] The clamping and cutting state detection method of the electric stapler in the embodiment of the present invention can detect tissue thickness data by setting a plurality of clamping thickness detection units 110 on the stapler seat 210, and the clamping thickness detection unit 110 is set outside the stapler forming groove 211, and will not interfere with the suturing process of the electric stapler. The cutting resistance detection unit 140 is set on the side of the cutter head 240 to detect the cutting resistance, and the cutting resistance detection unit 140 is set on the side of the cutter head 240 to effectively avoid the impact on the cutting of the cutter head 240. Compared with the traditional clamping pressure display method, the clamping and cutting state detection method of the electric stapler in the embodiment of the present invention has the ability to detect the clamping thickness and cutting resistance in real time, and can realize automatic protection according to the detected tissue thickness data and cutting resistance data, which greatly reduces the requirements for operators and is suitable for large-scale promotion and use.

[0084] In some embodiments, the current working state includes a current clamping state and a current cutting resistance state;

[0085] The clamping and cutting states of the electric stapler are adjusted according to multiple tissue thickness data and cutting resistance data, including:

[0086] determining a current clamping state according to a plurality of tissue thickness data;

[0087] When the resistance thickness of the electric stapler represented by the current clamping state exceeds the preset threshold value of tissue thickness, the electric stapler is stopped;

[0088] Determine the current cutting resistance state according to the cutting resistance data;

[0089] When the current cutting resistance state indicates that the cutting resistance of the electric stapler exceeds a preset threshold value of the cutting resistance, the action of the electric stapler is stopped.

[0090] The clamping thickness detection unit 110 may be a clamping pressure sensor or a clamping pressure detection switch. The clamping pressure sensor can realize continuous detection of the clamping pressure, and the control unit 120 can obtain these continuous clamping pressure data, and then use these clamping pressure data to obtain tissue thickness data. Here is a brief description of how to use the clamping pressure data to obtain the clamping thickness data. First of all, it can be understood that the rotation of the rotating clamping member 230 is driven by the motor inside the electric stapler using the transmission structure. Therefore, the rotation angle of the rotating clamping member 230 can be determined by the number of rotations and the rotation position of the motor. When it is determined through the clamping pressure data that the clamping of the tissue has been completed, the action of the rotating clamping member 230 will be stopped. At this time, the rotation angle of the rotating clamping member 230 can be determined according to the number of rotations and the rotation position of the motor. The thickness of the currently clamped tissue can be determined by the installation position of the pressure sensor on the nail seat 210, and multiple thicknesses can be determined by using multiple pressure sensors. Subsequently, the average value calculation or weighted average calculation is performed to obtain tissue thickness data that is as close to the actual thickness of the tissue as possible. The current clamping state can be determined by using the tissue thickness data and the preset threshold value of the tissue thickness. In addition, in actual operation, the pressure sensor will not be completely parallel to the tissue during clamping, and the greater the thickness of the tissue, the greater the angle formed. Therefore, a large amount of clamping pressure data can be used to construct a correlation between clamping pressure and tissue thickness. Generally, the thinner the tissue thickness, the greater the pressure change in the same time, so this correlation can be used to determine the tissue thickness. In addition, the tissue thickness data calculated by the control unit 120 can be displayed by the display unit 130. It should also be noted that in extreme cases, a unified pressure preset threshold value can be directly set to replace the tissue thickness preset threshold value, that is, as long as the clamping pressure monitored by the pressure sensor exceeds the pressure preset threshold value, the current tissue thickness is assumed to be too thick, and the electric stapler can be directly stopped. In this application mode, a clamping pressure detection switch can be used as a substitute. The clamping pressure detection switch can directly change the output state when the preset pressure value is reached. The control unit 120 determines that the clamping thickness is abnormal according to the current clamping state and controls the electric stapler to stop working.

[0091] The cutting resistance detection unit 140 can use a cutting pressure sensor or a cutting pressure detection switch. The pressure sensor is set on the side of the cutter head 240, and can detect the pressure from the front when the cutter head 240 is pushed forward. The pressure data can intuitively reflect the current cutting resistance. When pressure sensors are set on both sides of the cutter head 240, two pressure data can be obtained by detecting the cutting resistance at both ends of the cutter head 240, and then the mean value can be obtained by average calculation. This value can better represent the current cutting resistance, that is, the mean value is converted using a position conversion coefficient (the position conversion coefficient needs to be obtained by considering the measurement deviation between the side and front of the cutter head 240). After that, the cutting resistance data can be obtained. When the detected cutting resistance data is greater than the preset threshold value of the cutting resistance, the current cutting resistance state represents that the cutting resistance is abnormal, and the electric stapler is controlled to stop the action to avoid causing damage to the tissue. On the contrary, the current cutting resistance state represents that the cutting resistance is normal, and the cutter head 240 continues to be pushed forward. In addition, the cutting resistance data calculated by the control unit 120 can be displayed by the display unit 130. It should be noted that in some cases, it is not necessary to continuously detect the cutting resistance data. It is only necessary to determine whether the current cutting resistance data exceeds the preset threshold value of the cutting resistance. At this time, the pressure detection switch can be directly used for detection. When the cutting resistance is greater than the preset threshold value of the cutting resistance, that is, when the pressure detection switch detects that the pressure is greater than the preset pressure value (this value corresponds to the preset threshold value of the cutting resistance, that is, the preset threshold value of the cutting resistance is obtained by converting the preset pressure value through the position conversion coefficient), the output state will be directly changed, and the control unit 120 will determine the current cutting state as an abnormal cutting resistance and control the electric stapler to stop working.

[0092] It should also be noted that when using a clamping pressure sensor for detection, if there is a clamping pressure sensor that cannot detect pressure data, the clamping pressure sensor may be faulty, and then an early warning will be issued through the display unit 130 to prompt the operator to conduct detection and eliminate the fault in time, and when performing mean calculation to determine the displayed clamping pressure, the data detected by the clamping pressure sensor will also be eliminated to avoid interference with pressure detection caused by a single abnormal data. When using a cutting pressure sensor for detection, if there is a cutting pressure sensor that cannot detect pressure data, then the cutting pressure sensor may be faulty, and then an early warning will be issued through the display unit 130 to prompt the operator to conduct detection and eliminate the fault in time.

[0093] In some embodiments, the electric stapler clamping and cutting state detection system further includes a display unit 130 , which is connected to the control unit 120 ;

[0094] The electric stapler clamping and cutting state detection method also includes:

[0095] The display state of the display unit 130 is adjusted according to the current clamping state and the current cutting resistance state.

[0096] The display unit 130 allows the operator to more intuitively view the current clamping and cutting status, which is more convenient for the operator to use. At the same time, the display unit 130 can be used to display some early warning information, so as to remind the operator to make adjustments in time when abnormalities occur.

[0097] like Figure 1 As shown, in some embodiments, the display unit 130 is disposed on the top of the gun body of the electric stapler. The display unit 130 disposed on the top can be more convenient for the operator to observe.

[0098] In some embodiments, the display unit 130 includes an LED display unit connected to the control unit 120. The display unit 130 can directly use an LED display unit. For example, different colors of LED indicator lights can be used to indicate the current working state. The first color indicator light indicates that the clamping thickness is normal, the second color indicator light indicates that the clamping thickness is abnormal, the third color indicator light indicates that the cutting resistance is normal, and the fourth color indicator light indicates that the cutting resistance is abnormal. The four color indicator lights can use different colors, or a combination of color and flashing frequency can be used. It should be noted that the current working state can be divided more accurately according to actual needs. At this time, the number, color, and flashing frequency of the indicator lights can also be appropriately adjusted according to needs.
