Description

Technical Field

[0001] This application belongs to the technical field of medical devices, and more specifically, relates to a stapler. Background Art

[0002] A stapler is a medical device used to replace manual tissue suturing. Whether it is an electric or manual stapler, the structure of the stapler is similar, consisting of a cartridge assembly, an anvil, a cartridge seat, a cutting knife, an instrument body, and other structures. During surgery, the tissue to be anastomosed is clamped and bitten between the cartridge assembly and the anvil. When the firing button is pressed, the staples in the cartridge assembly are pushed out by a wedge block to anastomose the tissue. However, in actual application, when the anvil and the cartridge assembly clamp the tissue, there may be a vacant state between the distal ends of the anvil and the cartridge assembly, that is, no tissue is located between the distal ends of the anvil and the cartridge assembly. The staples at these positions that do not correspond to the tissue will fall into the human body cavity after being fired, posing a danger to the human body. At the same time, manual cleaning is required, which increases the operation steps and greatly reduces the surgical efficiency. Summary of the Invention

[0003] The purpose of this application is to provide a stapler to solve the technical problem of empty firing of staples in the prior art.

[0004] To achieve the above purpose, the technical solution adopted in this application is:

[0005] Provide a stapler, which includes:

[0006] An anvil, the anvil has a first clamping surface, and a plurality of staple forming pits are arranged on the first clamping surface;

[0007] A cartridge component, the side of the cartridge component facing the anvil has a second clamping surface, and a plurality of staple outlets are arranged on the second clamping surface;

[0008] An area detection component, the area detection component is arranged on the first clamping surface and / or the second clamping surface, and the area detection component is used to detect the contact situation between the first clamping surface or the second clamping surface and the tissue to be anastomosed when the anvil and the cartridge component clamp the tissue to be anastomosed;

[0009] A controller, the controller controls the anastomosis length of the stapler according to the contact situation.

[0010] The staple magazine component and the staple anvil jointly squeeze the tissue to be stapled of the working object, that is, the tissue to be stapled is clamped between the first clamping surface and the second clamping surface. By setting the area detection component on the first clamping surface and / or the second clamping surface, the contact situation between the first clamping surface or the second clamping surface and the tissue to be stapled can be obtained, and then the areas where the tissue to be stapled exists can be identified, so that the controller calculates the target staple length when firing the staples according to the contact situation, thereby avoiding empty firing or over-firing of the staples, thereby effectively reducing the fired staples from falling into the cavity of the working object, and more effectively protecting the safety of the working object.

[0011] As an implementation manner, the area detection component includes sensors, and the sensors are distributed at least along the length direction of the first clamping surface or the second clamping surface.

[0012] The length direction dimension span of the first clamping surface and the second clamping surface is relatively large, so it is likely that there is clamped tissue in some positions of the first clamping surface and the second clamping surface in the length direction, while there is no clamped tissue in other positions. Therefore, the sensor is distributed along the length direction of the first clamping surface or the second clamping surface to identify the contact condition in the length direction of the first clamping surface or the second clamping surface, thereby improving the accuracy of the contact condition in the length direction, thereby reducing the risk of empty firing or over-firing of the staples.

[0013] As an implementation manner, the area detection component further includes a detection carrier, the detection carrier is arranged on the first clamping surface or the second clamping surface, and all the sensors are arranged on the detection carrier.

[0014] By arranging all the sensors on the detection carrier, all the sensors can be formed into a whole, thereby effectively improving the overall assembly and disassembly efficiency of the sensor and the first clamping surface or the second clamping surface.

[0015] As an implementation mode, a clearance opening is provided on the detection carrier, and the clearance opening avoids the nail outlet opening or the nail forming pit; and the sensor is arranged at the periphery of the clearance opening.

[0016] By arranging the sensor around the yield opening, it is equivalent to arranging the sensor around the staple outlet or the forming pit, thereby being able to identify whether the firing position of each staple is within the contact area, thereby avoiding empty firing or over-firing of any staple to the greatest extent.

[0017] As an implementation manner, the area detection component further includes a plurality of suction components, and the suction components are used to fix the detection carrier on the first clamping surface or the second clamping surface.

[0018] By providing the suction components, a detachable connection between the area detection component and the first clamping surface or the second clamping surface can be achieved, so that the area detection component can be used multiple times within a certain range.

[0019] As an implementation manner, at least one of the suction components is a contact electrode. When the contact electrode is in contact with the first clamping surface or the second clamping surface, the contact electrode powers on the sensor.

[0020] By setting at least one of the suction components as a contact electrode and powering on the sensor when the contact electrode is in contact with the first clamping surface or the second clamping surface, the contact electrode forms a control structure similar to a switch, which can enable these sensors to start working when the area detection component is assembled with the first clamping surface or the second clamping surface, and enable these sensors to stop working when the area detection component is separated from the first clamping surface or the second clamping surface, so as to effectively control the start and stop of the sensor work.

[0021] As an implementation manner, the area detection component further includes a first wireless unit, the first wireless unit is arranged on the detection carrier, and the first wireless unit is electrically connected to the sensor; the stapler further includes a handle and a second wireless unit, the second wireless unit and the controller are both arranged on the handle, the second wireless unit is electrically connected to the controller, and the first wireless unit and the second wireless unit can perform signal interaction.

[0022] By providing the first wireless unit and the second wireless unit and arranging the controller on the handle, on the one hand, the weight of the distal end of the stapler can be reduced, thereby improving the operation convenience and flexibility of the stapler. On the other hand, it can avoid a wired connection between the area detection component and other components at the proximal end of the stapler, reduce the connection difficulty between the area detection component and other components of the stapler, and thus facilitate the rapid disassembly, replacement and installation of the area detection component.

[0023] As an implementation manner, the area detection component further includes a power supply unit, and the power supply unit is electrically connected to the sensor and the first wireless unit.

[0024] By providing the first wireless unit and the power supply unit on the detection carrier, the power supply of the area detection component is supplied internally by itself, and data is interacted with the outside through the first wireless unit. As a result, the area detection component becomes a component that can work independently internally and does not require a wired connection to the outside, reducing the connection difficulty between the area detection component and other components of the stapler, and thus enabling the quick disassembly, replacement, and installation of the area detection component to be thoroughly realized.

[0025] As an implementation manner, the stapler further includes a display component, which is arranged on the handle and electrically connected to the controller.

[0026] By providing the display component, the contact situation information can be more intuitively displayed, so that the user can intuitively judge the firing area.

[0027] As an implementation manner, the sensor includes a pressure sensor.

[0028] By setting the sensor as a pressure sensor, the pressure values at different positions on the first clamping surface or the second clamping surface in the squeezing state can be obtained through the pressure sensor, and then it can be judged that there is no tissue at the position where the pressure value on the first clamping surface or the second clamping surface is less than the preset value. Thus, a contact area can be formed based on the pressure value, and finally, the controller calculates the target anastomosis length when firing the anastomosis staple according to the contact area.

[0029] The beneficial effects of the stapler provided by this application are as follows:

[0030] The cartridge component and the anvil jointly squeeze the tissue to be anastomosed of the operation object, that is, the tissue to be anastomosed is clamped between the first clamping surface and the second clamping surface. By providing the area detection component on the first clamping surface and / or the second clamping surface, the contact situation between the first clamping surface or the second clamping surface and the tissue to be anastomosed can be obtained, and then it can be recognized which areas have the tissue to be anastomosed. Thus, the controller calculates the target anastomosis length when firing the anastomosis staple according to the contact situation, avoiding misfiring or overfiring the anastomosis staple, effectively reducing the dropped anastomosis staples in the cavity of the operation object, and more effectively protecting the safety of the operation object.

[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more, unless otherwise specifically defined.

[0050] An embodiment of the present application provides a stapler, as Figure 1 shown. The stapler includes an anvil 1, a cartridge assembly 2, a region detection component 3, and a controller. The anvil 1 has a first clamping surface 11, and a plurality of staple forming pits are provided on the first clamping surface 11; one side of the cartridge assembly 2 facing the anvil 1 has a second clamping surface 21, and a plurality of staple outlets are provided on the second clamping surface 21; the region detection component 3 is disposed on the first clamping surface 11 and / or the second clamping surface 21. The region detection component 3 is used to detect the contact situation between the first clamping surface 11 or the second clamping surface 21 and the tissue to be anastomosed 100 when the anvil 1 and the cartridge assembly 2 clamp the tissue to be anastomosed 100; the controller controls the anastomosis length of the stapler according to the contact situation.

[0051] The cartridge assembly 2 and the anvil 1 jointly press the tissue to be anastomosed 100 of the operation object, that is, the tissue to be anastomosed 100 is clamped between the first clamping surface 11 and the second clamping surface 21. By providing the region detection component 3 on the first clamping surface 11 and / or the second clamping surface 21, the contact situation between the first clamping surface 11 or the second clamping surface 21 and the tissue to be anastomosed 100 can be obtained, and then it can be identified which regions have the tissue to be anastomosed 100. Thus, the controller calculates the target anastomosis length when firing the staple according to the contact situation, avoiding misfiring or overfiring of the staple, thereby effectively reducing the staples that fall into the cavity of the operation object during firing and more effectively protecting the safety of the operation object.

[0052] In one embodiment, detecting the contact situation specifically means detecting which positions are the contact areas. In this case, the stapler is designed as follows: The stapler includes an anvil 1, a cartridge assembly 2, an area detection component 3, and a controller. The anvil 1 has a first clamping surface 11, and a plurality of nail forming pits are provided on the first clamping surface 11; one side of the cartridge assembly 2 facing the anvil 1 has a second clamping surface 21, and a plurality of nail outlets are provided on the second clamping surface 21; the area detection component 3 is arranged on the first clamping surface 11 and / or the second clamping surface 21, and the area detection component 3 is used to detect the contact area between the first clamping surface 11 or the second clamping surface 21 and the tissue to be anastomosed 100 when the anvil 1 and the cartridge assembly 2 clamp the tissue to be anastomosed 100; the controller controls the anastomosis length of the stapler according to the contact area. The cartridge assembly 2 and the anvil 1 jointly press the tissue to be anastomosed 100 of the operation object, that is, the tissue to be anastomosed 100 is clamped between the first clamping surface 11 and the second clamping surface 21. By arranging the area detection component 3 on the first clamping surface 11 and / or the second clamping surface 21, the contact area between the first clamping surface 11 or the second clamping surface 21 and the tissue to be anastomosed 100 can be obtained, and then it can be recognized which areas have the tissue to be anastomosed 100, so that the controller can calculate the target anastomosis length when firing the anastomosis nails according to the contact area, avoiding misfiring or overfiring of the anastomosis nails, thereby effectively reducing the dropped anastomosis nails in the cavity of the operation object and more effectively protecting the safety of the operation object.

[0053] Of course, in other embodiments, the detection of the contact situation may specifically be the detection of non-contact areas at certain positions. In this case, the stapler is designed as follows: The stapler includes an anvil 1, a cartridge member 2, an area detection member 3, and a controller. The anvil 1 has a first clamping surface 11, and a plurality of staple forming pits are provided on the first clamping surface 11; on the side of the cartridge member 2 facing the anvil 1, there is a second clamping surface 21, and a plurality of staple outlets are provided on the second clamping surface 21; the area detection member 3 is arranged on the first clamping surface 11 and / or the second clamping surface 21, and the area detection member 3 is used to detect the non-contact area between the first clamping surface 11 or the second clamping surface 21 and the tissue 100 to be anastomosed when the anvil 1 and the cartridge member 2 clamp the tissue 100 to be anastomosed; the controller calculates the contact area based on the non-contact area, and further controls the anastomosis length of the stapler. The cartridge member 2 and the anvil 1 jointly press the tissue 100 to be anastomosed of the working object, that is, the tissue 100 to be anastomosed is clamped between the first clamping surface 11 and the second clamping surface 21. By arranging the area detection member 3 on the first clamping surface 11 and / or the second clamping surface 21, the non-contact area between the first clamping surface 11 or the second clamping surface 21 and the tissue 100 to be anastomosed can be obtained, and then it can be identified which areas have the tissue 100 to be anastomosed and which areas do not have the tissue 100 to be anastomosed. Thus, the controller calculates the target anastomosis length when firing the staples according to the non-contact area, avoiding misfiring or overfiring the staples, effectively reducing the staples that are fired and fall into the cavity of the working object, and more effectively protecting the safety of the working object.

[0054] In the specific implementation process, the size of the area detection member 3 is adaptively designed according to the specifications of the cartridge member 2.

[0055] In one embodiment, as Figures 2 to 5 shown, the area detection member 3 includes a sensor 31, and the sensor 31 is at least distributed along the length direction of the first clamping surface 11 or the second clamping surface 21. The length direction dimensions of the first clamping surface 11 and the second clamping surface 21 have a large span, making it more likely that there are parts of the first clamping surface 11 and the second clamping surface 21 where the clamped tissue 100 exists in some positions in the length direction, while the clamped tissue 100 does not exist in other positions. Therefore, the sensor 31 is distributed along the length direction of the first clamping surface 11 or the second clamping surface 21 to identify the contact situation in the length direction of the first clamping surface 11 or the second clamping surface 21, thereby improving the accuracy of the contact situation in the length direction, and reducing the risk of misfiring or overfiring the staples.

[0056] In the specific implementation process, the number of sensors 31 is more than two, and the more than two sensors 31 are at least spaced apart along the length direction of the first clamping surface 11 or the second clamping surface 21. Of course, the sensor 31 can also be a strip-shaped sensor, the sensor 31 extends at least along the length direction of the first clamping surface 11 or the second clamping surface 21, and the length of the sensor 31 is set according to the length of the first clamping surface 11 or the second clamping surface 21.

[0057] Of course, in other embodiments, it can also be designed as the following structure: as Figure 5 shown, sensors 31 are arranged at intervals in both the length direction and the width direction of the first clamping surface 11 or the second clamping surface 21.

[0058] In one embodiment, as Figures 2 to 5 shown, the area detection component 3 further includes a detection carrier 32, the detection carrier 32 is arranged on the first clamping surface 11 or the second clamping surface 21, and all the sensors 31 are arranged on the detection carrier 32. By arranging all the sensors 31 on the detection carrier 32, all the sensors 31 can be formed into a whole, thereby effectively improving the overall assembly and disassembly efficiency of the sensors 31 and the first clamping surface 11 or the second clamping surface 21.

[0059] In the specific implementation process, the detection carrier 32 is a flexible carrier. The detection carrier 32 covers the entire first clamping surface 11 or the second clamping surface 21.

[0060] In one embodiment, as Figures 2 to 5 shown, a relief opening 33 is arranged on the detection carrier 32, and the relief opening 33 avoids the nail ejection opening or the nail forming pit; the sensor 31 is arranged on the periphery of the relief opening 33.

[0061] By arranging the sensor 31 on the periphery of the relief opening 33, it is equivalent to arranging the sensor 31 on the periphery of the nail ejection opening or the forming pit, and thus it can be recognized whether the firing position of each staple is within the contact area, so as to avoid misfiring or overfiring of any staple to the greatest extent.

[0062] In the specific implementation process, as Figure 5 shown, sensors 31 are arranged at both ends of the relief opening 33 along the length direction of the second clamping surface 21. Further, one sensor 31 is shared between two adjacent relief openings 33 in the length direction.

[0063] Of course, in other embodiments, it can also be designed as the following structure: as Figure 5 shown, corresponding to the design that sensors 31 are arranged at intervals in both the length direction and the width direction of the first clamping surface 11 or the second clamping surface 21, nail ejection openings are arranged at intervals in both the length direction and the width direction of the second clamping surface 21.

[0064] In one embodiment, as Figure 6 shown, the area detection component 3 further includes a plurality of suction components 34, and the suction components 34 are used to fix the detection carrier 32 on the first clamping surface 11 or the second clamping surface 21. In the specific implementation process, the plurality of suction components 34 are arranged at intervals on the periphery of the detection carrier 32.

[0065] By providing the suction components 34, a detachable connection between the area detection component 3 and the first clamping surface 11 or the second clamping surface 21 can be realized, so that the area detection component 3 can be used multiple times within a certain range.

[0066] In the specific implementation process, the suction components 34 are arranged on the side of the detection carrier 32 where the sensor 31 is not installed.

[0067] In the specific implementation process, the area detection component 3 further includes a disassembly structure, and the disassembly structure is arranged on the edge of the detection carrier 32. The disassembly structure is used to assist the user in disassembling the area detection component 3 from the first clamping surface 11 or the second clamping surface 21.

[0068] In the specific implementation process, the suction component 34 is a magnetic component.

[0069] In one embodiment, at least one suction component 34 is a contact electrode. In a state where the contact electrode is in contact with the first clamping surface 11 or the second clamping surface 21, the contact electrode powers on the sensor 31.

[0070] By setting at least one suction component 34 as a contact electrode and powering on the sensor 31 in a state where the contact electrode is in contact with the first clamping surface 11 or the second clamping surface 21, the contact electrode forms a control structure similar to a switch, which can enable these sensors 31 to start working in a state where the area detection component 3 is assembled with the first clamping surface 11 or the second clamping surface 21, and enable these sensors 31 to stop working in a state where the area detection component 3 is separated from the first clamping surface 11 or the second clamping surface 21, so as to effectively control the start and stop of the sensor 31.

[0071] In the specific implementation process, as Figure 2 and Figure 6 shown, the first clamping surface 11 or the second clamping surface 21 is a rectangular structure, the number of the suction components 34 is four, and the four suction components 34 are respectively arranged at the four corner positions of the rectangle. Further, the number of the contact electrodes is two, and the two contact electrodes are located at the two corner positions at the far ends on the first clamping surface 11 or the second clamping surface 21.

[0072] In one embodiment, as Figure 2 and Figure 7As shown, the area detection component 3 further includes a first wireless unit 35. The first wireless unit 35 is disposed on the detection carrier 32 and is electrically connected to the sensor 31. The stapler further includes a handle 4 and a second wireless unit. The second wireless unit and the controller are both disposed on the handle 4. The second wireless unit is electrically connected to the controller, and the first wireless unit 35 and the second wireless unit can interact with each other in terms of signals.

[0073] By providing the first wireless unit 35 and the second wireless unit and disposing the controller on the handle 4, on the one hand, the weight at the distal end of the stapler can be reduced, thereby improving the convenience and flexibility of operating the stapler. On the other hand, it can avoid a wired connection between the area detection component 3 and other components at the proximal end of the stapler, reducing the connection difficulty between the area detection component 3 and other components of the stapler, which is conducive to achieving rapid disassembly, replacement, and installation of the area detection component 3.

[0074] Certainly, in other embodiments, the sensor 31 can also be connected to the controller through a signal line. In this case, the above-mentioned first wireless unit 35 and second wireless unit do not need to be provided for this stapler.

[0075] In one embodiment, as Figure 5 shown, the area detection component 3 further includes a power supply unit 36. The power supply unit 36 is electrically connected to the sensor 31 and the first wireless unit 35.

[0076] By providing the first wireless unit 35 and the power supply unit 36 on the detection carrier 32, the power supply of the area detection component 3 is supplied internally by itself, and the data is interacted with the outside through the first wireless unit 35. Furthermore, the area detection component 3 becomes a component that can work independently inside and does not need to be connected to the outside by wire, reducing the connection difficulty between the area detection component 3 and other components of the stapler, and thus can completely achieve rapid disassembly, replacement, and installation of the area detection component 3.

[0077] In the specific implementation process, the first wireless unit 35 is disposed at the distal end of the detection carrier 32, and the power supply unit 36 is disposed at the proximal end of the detection carrier 32.

[0078] In one embodiment, the area detection component 3 further includes a power supply unit 36. The power supply unit 36 is disposed on the detection carrier 32 and is electrically connected to the sensor 31 and the first wireless unit 35. Wherein the two suction members 34 are contact electrodes. When the two contact electrodes are turned on, the sensor 31 and the first wireless unit 35 can be powered on. In a state where the two contact electrodes are in contact with the first clamping surface 11 or the second clamping surface 21, the two contact electrodes are turned on. Of course, in other embodiments, it can also be designed that the area detection component 3 further includes a power supply unit 36. The power supply unit 36 is disposed on the handle 4 and is electrically connected to the sensor 31 and the first wireless unit 35. Wherein one of the suction members 34 is a contact electrode. In a state where the contact electrode is in contact with the first clamping surface 11 or the second clamping surface 21, the contact electrode is turned on with the power supply unit 36, and the sensor 31 and the first wireless unit 35 can be powered on.

[0079] When the power supply unit 36 is disposed on the detection carrier 32, by setting the two suction members 34 as contact electrodes and the two contact electrodes being turned on in a state of being in contact with the first clamping surface 11 or the second clamping surface 21, a control structure similar to a switch is formed, and the power-on of the pressure sensor 31 and the first wireless unit 35 is triggered by the on-state of the two contact electrodes. It can enable the sensors 31 and the first wireless unit 35 to start working in a state where the area detection component 3 is assembled with the first clamping surface 11 or the second clamping surface 21, and enable the sensors 31 and the first wireless unit 35 to stop working in a state where the area detection component 3 is separated from the first clamping surface 11 or the second clamping surface 21, thereby realizing effective control of the start and stop of the work of the sensor 31 and the first wireless unit 35. When the power supply unit 36 is disposed on the handle 4, by setting one of the suction members 34 as a contact electrode and the sensor 31 and the first wireless unit 35 being turned on with the power supply unit 36 in a state where the contact electrode is in contact with the first clamping surface 11 or the second clamping surface 21, that is, the sensor 31 and the first wireless unit 35 are powered on, and the contact electrode forms a control structure similar to a switch, it can enable the sensors 31 and the first wireless unit 35 to start working in a state where the area detection component 3 is assembled with the first clamping surface 11 or the second clamping surface 21, and enable the sensors 31 and the first wireless unit 35 to stop working in a state where the area detection component 3 is separated from the first clamping surface 11 or the second clamping surface 21, thereby realizing effective control of the start and stop of the work of the sensor 31 and the first wireless unit 35.

[0080] In one embodiment, the area detection component 3 is arranged on the second clamping surface 21. The staple cartridge component 2 includes a staple cartridge assembly 22 and a staple cartridge base 23. The second clamping surface 21 is arranged on the side of the staple cartridge assembly 22 facing the anvil 1. The detection carrier 32 is adhered to the second clamping surface 21, and conduction surfaces are respectively arranged on both sides of the detection carrier 32. The conduction of the two conduction surfaces can trigger the sensor 31 and the first wireless unit 35 to work. In the state where the staple cartridge assembly 22 and the staple cartridge base 23 are assembled, the two conduction surfaces are conducted.

[0081] First, by adhering the detection carrier 32 to the second clamping surface 21, the connection reliability between the area detection component 3 and the second clamping surface 21 can be ensured. Secondly, by arranging two conduction surfaces, and the two conduction surfaces are conducted in the state where the staple cartridge assembly 22 and the staple cartridge base 23 are assembled, a control structure similar to a switch is formed, and the conduction state of the two conduction surfaces is used to trigger the sensor 31 and the first wireless unit 35 to work, so that these sensors 31 and the first wireless unit 35 can be started to work in the state where the staple cartridge assembly 22 and the staple cartridge base 23 are assembled, and these sensors 31 and the first wireless unit 35 can be stopped from working in the state where the staple cartridge assembly 22 and the staple cartridge base 23 are separated, thereby realizing effective control of the start and stop of the work of the sensor 31 and the first wireless unit 35.

[0082] In one embodiment, as Figure 7 shown, the stapler further includes a display component 5. The display component 5 is arranged on the handle 4, and the display component 5 is electrically connected to the controller. By arranging the display component 5, the contact situation information can be more intuitively displayed, so that the user can intuitively judge the firing area.

[0083] In one embodiment, the sensor 31 includes a pressure sensor. By setting the sensor 31 as a pressure sensor, the pressure values at different positions on the first clamping surface 11 or the second clamping surface 21 in the squeezing state can be obtained through the pressure sensor, and then it can be judged that there is no tissue 100 at the position where the pressure value on the first clamping surface 11 or the second clamping surface 21 is less than the preset value. Thus, a contact area can be formed according to the pressure value, and finally the controller can calculate the target anastomosis length when firing the anastomosis staple according to the contact area. Of course, the sensor 31 is not limited to being a pressure sensor. In other embodiments, the sensor 31 can also be other types of sensors, such as an infrared sensor.

[0084] Of course, in other embodiments, it can also be designed that the sensor 31 array is distributed on one of the first clamping surface 11 and the second clamping surface 21. The sensor 31 is a positive electrode contact, and a negative electrode contact is provided on the other of the first clamping surface 11 and the second clamping surface 21. When the tissue 100 is clamped, the positive electrode contacts in the areas where the tissue 100 exists will detect electrical signals, and then it can be determined that these areas are the contact areas of the clamped tissue 100, so as to further obtain the anastomosis length through the controller.

[0085] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
