Description

Technical Field

[0001] This invention patent relates to the technical field of automatic parameter configuration of electric staplers. Specifically, it relates to an automatic configuration method for electric staplers and an automatically configured electric stapler. Background Art

[0002] In minimally invasive abdominal surgery, staplers are increasingly being used due to their advantages such as simple operation, small trauma surface, and rapid postoperative recovery, and have played an important role in promoting the development of surgical techniques. Depending on the location of the lesion, the stapler needs to be adapted to different specifications of execution components to perform the surgery. Usually, the surgeon selects a suitable execution component for assembly before the surgery and configures the parameters of the stapler according to the selected execution component.

[0003] Currently, in order not to affect the concentration of the surgeon and avoid the surgeon from configuring the parameters of the execution component, automatic recognition is used to meet the parameter configuration of the execution component. For example, the prior patent with the authorization announcement number CN217430084U discloses an automatic recognition device for the execution component of a stapler. The stapler includes a stapler body and at least one execution component. The stapler body includes a distal engagement portion, and the execution component includes a proximal engagement portion that can engage with the distal engagement portion. A controller is provided in the stapler body. The automatic recognition device for the execution component includes: at least one magnetic mark setting position provided on the proximal engagement portion of the execution component, where the magnetic mark can be set; and at least one Hall sensor installed on the distal engagement portion of the stapler body. When the execution component engages with the stapler body, the Hall sensor corresponds one-to-one with the magnetic mark setting position, so that the Hall sensor can detect whether there is a magnetic mark in the corresponding magnetic mark setting position, and / or detect the magnetic flux magnitude of the magnetic mark in the magnetic mark setting position, and transmit the corresponding electrical signal generated to the controller.

[0004] In the prior art, the automatic recognition of the execution component is achieved by the one-to-one correspondence between the Hall sensor and the magnetic mark setting position. This non-contact automatic recognition is susceptible to interference, factors such as the aging of the Hall sensor, resulting in insufficient accuracy of automatic recognition, and easily causing the stapler to malfunction or perform incorrect operations, affecting surgical safety. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic configuration method for electric staplers and an automatically configured electric stapler, aiming to solve the problem that the automatic parameter configuration of electric staplers in the prior art is susceptible to interference.

[0006] The present invention is implemented as follows. An automatic configuration method for an electric stapler includes a stapler main body, a jaw assembly, and a detection assembly. The jaw assembly includes a jaw shell, a moving block, and a conductive member. The jaw shell has at least one configuration groove for the detection assembly to be embedded. The conductive member is electrically connected to the stapler main body. The specific automatic configuration steps are as follows: (1) Assemble the jaw assembly with the stapler main body. After the stapler main body completes self-checking, it enters the execution operation, and the execution operation triggers the output of a firing instruction. (2) The moving block axially moves along the jaw shell based on the firing instruction until the moving block applies a force to the detection assembly. (3) Type I jaw assembly: Before leaving the factory, there is an initial distance between the initial position of the moving block and the detection assembly, defining different specifications of Type I jaw assemblies corresponding to different initial distances. When the detection assembly is acted on by the moving block, it is electrically connected to the conductive member, and the conduction signal triggers the stapler main body to record the current travel data as the initial distance. The stapler main body identifies the specification of the Type I jaw assembly based on the initial distance. Type II jaw assembly: The detection assembly includes a characteristic device. When the characteristic device is acted on by the moving block, it is electrically connected to the conductive member and outputs electrical parameters to the stapler main body. The stapler main body identifies the specification of the Type II jaw assembly based on the electrical parameters of the characteristic device. (4) The stapler main body retrieves corresponding parameters based on the identified specification of the jaw assembly and automatically completes the parameter configuration of the jaw assembly.

[0007] Further, in step (3), the jaw has a plurality of the configuration grooves, and the configuration grooves are arranged at intervals along the axial direction of the jaw shell. The conductive member extends along the axial direction and lies flat in each of the configuration grooves.

The first reed and the second reed are respectively arranged on the detection block, and the first reed and the second reed clamp the characteristic device with the detection block. The first reed and the second reed are respectively arranged in a conductive manner with the characteristic device. The moving block is used to cause the first reed and the second reed to be respectively arranged in a conductive manner with the first conductive strip and the second conductive strip.

[0010] Further, the jaw housing has a positioning groove. The positioning groove includes an upper positioning groove and a lower positioning groove. The upper positioning groove and the lower positioning groove are arranged in a communicating manner. The detection assembly includes a block fixing pin. The inner end of the block fixing pin is arranged in a butt joint manner with the detection block. The outer end of the block fixing pin is embedded in the upper positioning groove. The moving block is used to apply a force to cause the block fixing pin to move along the upper positioning groove to the lower positioning groove. When the block fixing pin moves to the lower positioning groove, the detection assembly is arranged in a conductive manner with the conductive member. A constriction section is formed between the upper positioning groove and the lower positioning groove. The constriction section is used to limit the block fixing pin to move from the lower positioning groove to the upper positioning groove. In step (1), if after the jaw assembly is assembled with the stapler main body, it is detected that the detection assembly is arranged in a conductive manner with the conductive member, the used jaw assembly is identified, subsequent operations are rejected, and an alarm prompt is issued.

[0011] Further, the jaw assembly includes a flexible connection piece group. The flexible connection piece group axially passes through the jaw rail in a movable manner. The moving block is assembled with the flexible connection piece group. The flexible connection piece group is used to drive the moving block to move synchronously along the axial direction.

[0012] Further, the jaw housing has two jaw rails. The jaw rails extend along the axial direction. The two ends of the flexible connection piece group are respectively movably arranged on the two jaw rails. The jaw rails are used to cause the flexible connection piece group to move along a straight line. The jaw rails are arranged in the middle of the jaw housing. A rail middle area is formed between the two jaw rails. The configuration groove is arranged corresponding to the rail middle area.

[0013] Further, the detection block has a pressure receiving surface facing the moving block. The pressure receiving surface is arranged to gradually incline downward, and the pressure receiving surface is arranged in a curved surface shape along the direction away from the flexible connection piece group.

[0014] Further, a top block surface is formed on the top of the detection block. Along the radial direction, the top block surface is arranged in a gradually downward curved shape; and high face parts and low face parts are respectively formed at both ends of the top block surface.

[0021] Refer to Figures 1-9 as shown, which is a preferred embodiment provided by the present invention.

[0022] The automatic configuration method of the electric stapler includes a stapler main body 5, a jaw assembly 1 and a detection component 2. The jaw assembly 1 includes a jaw shell 11, a moving block 15 and a conductive member 3. The jaw shell 11 has at least one configuration groove 12 for the detection component 2 to be embedded. The conductive member 3 is arranged in conduction with the stapler main body 5. The specific automatic configuration steps are as follows: (1), Assemble the jaw assembly 1 with the stapler main body 5. After the stapler main body 5 completes self-checking, enter the execution operation, and the execution operation triggers the output of a firing instruction; (2), The moving block 15 moves axially along the jaw shell 11 based on the firing instruction until the moving block 15 applies a force to the detection component 2; (3) I-type jaw assembly 1: Before the jaw assembly 1 leaves the factory, there is a starting distance between the initial position of the moving block 15 and the detection assembly 2, defining different specifications of the I-type jaw assembly 1 corresponding to different starting distances; the detection assembly 2 is electrically connected to the conductive member 3 by the force of the moving block 15 and outputs an on-state signal to trigger the stapler host 5 to record the current travel data as the starting distance, and the stapler host 5 identifies the specifications of the I-type jaw assembly 1 based on the starting distance; Type II jaw assembly 1: the detection assembly 2 includes a characteristic device 4, which is electrically connected to the conductive member 3 by the force of the moving block 15 and outputs electrical parameters to the stapler host 5. The stapler host 5 identifies the specifications of the Type II jaw assembly 1 based on the electrical parameters of the characteristic device 4; (4) The stapler host 5 retrieves corresponding parameters based on the identified specifications of the jaw assembly 1 and automatically completes parameter configuration of the jaw assembly 1 .

[0023] In the above-mentioned automatic configuration method of the electric stapler, the stapler host 5 causes the moving block 15 to move by outputting a firing command, thereby realizing automatic identification of the specifications of the jaw assembly 1, thereby realizing automatic configuration of the parameters of the jaw assembly 1. There is no need for the doctor to configure the parameters, thereby simplifying the doctor's surgical operation. In addition, the moving block 15 directly applies a force to the detection component 2 to trigger the detection, which is not easily interfered with, thereby ensuring the accuracy of the identification of the specifications of the jaw assembly 1 and the accuracy of the parameter configuration, thereby improving the safety of the operation.

[0024] During clinical use, the jaw assembly 1 is clamped on the connecting sleeve at the front end of the stapler main unit 5. After the stapler main unit 5 completes the self-check, the stapler main unit 5 can be operated. The stapler main unit 5 outputs a firing instruction during the operation. The stapler main unit 5 automatically completes the corresponding parameter configuration of the jaw assembly 1 during the operation.

[0025] The jaw shell 11 has a positioning groove, which includes an upper groove 13 and a lower groove 14. The upper groove 13 and the lower groove 14 are connected. The detection component 2 includes a block pin 23. The inner end of the block pin 23 is connected to the detection block 21. The outer end of the block pin 23 is embedded in the upper groove 13. The moving block 15 is used to apply a force to cause the block pin 23 to move along the upper groove 13 to the lower groove 14. When the block pin 23 moves to the lower groove 14, the detection component 2 is connected to the conductive member 3. A constriction section is formed between the upper groove 13 and the lower groove 14. The constriction section is used to limit the block pin 23 from moving along the lower groove 14 to the upper groove 13. In step (1), if the jaw assembly 1 is assembled with the stapler main body 5, it is detected that the detection component 2 is connected to the conductive member 3, the jaw assembly 1 that has been used is identified, subsequent operations are refused, and an alarm prompt is issued.

[0026] In this way, the used jaw assembly 1, the detection assembly 2 and the conductive part 3 are in a conductive state. When the used jaw assembly 1 is installed into the stapler main unit 5 again, the stapler main unit 5 immediately detects the electrical connectivity state of the conductive part 3, refuses subsequent operations, and issues an alarm.

[0027] In this way, the jaw assembly 1 of the disposable actuator is identified, effectively avoiding the problem of reuse.

[0028] The jaw assembly 1 includes a flexible connecting piece group 16, which is movably arranged in the axial direction to penetrate the jaw rail, and the moving block 15 is assembled with the flexible connecting piece group 16, and the flexible connecting piece group 16 is used to drive the moving block 15 to move synchronously in the axial direction.

[0029] In this way, when the firing command is triggered, the flexible connecting piece group 16 is driven to move axially, driving the movement of the moving block 15 to detect the detection component 2 and recognize the specifications of the jaw assembly 1, thereby realizing automatic configuration of the parameters of the jaw assembly 1.

[0030] The jaw housing 11 has two jaw rails, which are arranged to extend in the axial direction. Two ends of the flexible connecting piece group 16 are movably mounted on the two jaw rails respectively, and the jaw rails are used to cause the flexible connecting piece group 16 to move in a straight line.

[0031] In this way, under the action of the two jaw rails, the movement of the flexible connecting plate group 16 is positioned and the deviation is limited, so that the flexible connecting plate group 16 moves in a straight line along the axial direction, and then the moving block 15 moves in a straight line along the axial direction, ensuring the accuracy of the force applied by the moving block 15 to the detection block 21.

[0032] The jaw rail is arranged in the middle of the jaw shell 11, and a rail center area is formed in the middle of the two jaw rails, and the configuration groove 12 is arranged corresponding to the rail center area; in this way, the moving block 15 is in the middle, so that the movement of the moving block 15 is more stable, thereby improving the movement stability of the flexible connecting piece group 16 through the cooperation of the jaw rail, and facilitating the moving block 15 to transfer the detection block 21 to the configuration groove 12.

[0033] The detection block 21 has a pressure surface 211 facing the moving block 15 . The pressure surface 211 is arranged to be gradually inclined downward and is arranged in a curved surface along a direction away from the flexible connecting sheet group 16 . The pressure surface 211 is used to receive the downward pressure applied by the moving block 15 .

[0034] In this way, under the action of the pressure surface 211, the contact between the moving block 15 and the detection block 21 is gradually reduced, the wear of the moving block 15 and the detection block 21 is reduced, the service life of the moving block 15 and the detection block 21 is increased, and at the same time, it helps to reduce the contact noise between the moving block 15 and the detection block 21.

[0035] The top of the detection block 21 forms a top block surface 212. Along the radial direction, the top block surface 212 is arranged in a gradually downward curved shape; and both ends of the top block surface 212 respectively form a high face part and a low face part, the horizontal height of the high face part is greater than that of the low face part. The first conductive strip 31 corresponds to the positive electrode, and the second conductive strip 32 corresponds to the negative electrode. The high face part is arranged corresponding to the first conductive strip 31, and the low face part is arranged corresponding to the second conductive strip 32.

[0036] In this way, when the detection block 21 is subjected to the downward pressure of the moving block 15, under the combined action of the high face part and the low face part, the first conductive strip 31 is first conducted, and then the second conductive strip 32 is conducted, improving the safety of circuit conduction. At the same time, the risk of damage to the electrical components of the stapler main body 5 and the jaw assembly 1 is reduced.

[0037] Under the action of the positioning groove, the assembled detection block 21 is arranged in a suspended manner, and the detection block 21 is placed in the configuration groove 12, so that the block spring piece 22 or the first spring piece 24 and the second spring piece 25 are respectively arranged corresponding to the first conductive strip 31 and the second conductive strip 32, facilitating subsequent contact conduction, and also preventing the moving block 15 from being unable to press the detection block 21 down into the configuration groove 12 to be in a conductive state, improving the cooperation effect between the detection block 21 and the configuration groove 12, and ensuring the accuracy of the specification identification of the jaw assembly 1.

[0038] The moving block 15 includes two transfer grooves 151. The flexible connection piece group 16 is synchronously embedded in the two transfer grooves 151, improving the assembly stability of the flexible connection piece group 16 and the moving block 15, and ensuring the driving of the moving block 15 by the flexible connection piece group 16.

[0039] The moving block 15 includes two cross plate parts 152. One transfer groove 151 is formed between the two cross plate parts 152. The cross plate parts 152 are arranged horizontally, and the end of the cross plate part 152 forms a cross plate surface 153. The cross plate surface 153 extends longitudinally, and the cross plate surface 153 is arranged in a flat contact with the jaw shell 11. Under the action of the cross plate surface 153, the moving stability of the moving block 15 is improved.

[0040] The moving block 15 includes two arc plate parts 154. The two arc plate parts 154 are arranged in one-to-one butt joint and integrally formed with the two cross plate parts 152. Another transfer groove 151 is formed between the two arc plate parts 154. The arc plate part 154 has an arc plate surface 155. The arc plate surface 155 is arranged in an arched shape along the direction away from the cross plate part 152. The two arc plate surfaces 155 are symmetrically arranged, and the two arc plate surfaces 155 are respectively arranged in a flat contact with the jaw shell 11, improving the moving stability of the moving block 15.

[0041] Under the combined action of the two cross plate parts 152 and the two arc plate parts 154, the rotation of the moving block 15 is restricted, facilitating the cooperation between the moving block 15 and the detection block 21.

[0042] Automatic parameter configuration for the Type I jaw assembly 1: In step (3), the jaw has a plurality of configuration slots 12, and the respective configuration slots 12 are arranged at intervals along the axial direction of the jaw housing 11. The conductive member 3 is arranged to extend along the axial direction, and the conductive member 3 lies flat on each of the configuration slots 12.

[0043] Through different configuration slots 12, the detection block 21 is assembled in one of the configuration slots 12 to complete the specification definition of the Type I jaw assembly 1.

[0044] That is to say, before the Type I jaw assembly 1 leaves the factory, the detection block 21 is assembled into one of the configuration slots 12, and this configuration slot 12 corresponds to the corresponding specification, completing the definition of the starting distance between the initial positions of the detection block 21 and the moving block 15, so as to realize the subsequent identification and parameter configuration of the Type I jaw assembly 1.

[0045] For example, the respective configuration slots 12 respectively correspond to the a specification, b specification, c specification, and d specification of the Type I jaw assembly 1. The detection block 21 is assembled in a certain configuration slot 12, that is, it is determined that the jaw assembly 1 is of the corresponding specification.

[0046] The conductive member 3 includes a first conductive strip 31 and a second conductive strip 32. The first conductive strip 31 and the second conductive strip 32 are respectively arranged to extend along the axial direction, and the first conductive strip 31 and the second conductive strip 32 are arranged at intervals corresponding to each other in the radial direction, and the first conductive strip 31 and the second conductive strip 32 respectively cover the configuration slots 12; the detection assembly 2 includes a detection block 21 and a block spring piece 22. The block spring piece 22 is arranged on the detection block 21, the block spring piece 22 is arranged in the direction towards the configuration slot 12, and the moving block 15 is used to cause the block spring piece 22 to be in a conductive arrangement with the first conductive strip 31 and the second conductive strip 32.

[0047] In this way, when the moving block 15 moves to apply a force to the detection block 21, the detection block 21 is pressed and moves to drive the block spring piece 22 to move, so that the block spring piece 22 contacts and conducts with the conductive member 3, and the feedback signal triggers the stapler host 5 to judge the starting distance between the initial positions of the detection block 21 and the moving block 15, thereby identifying the specification of the jaw assembly 1 and automatically completing the parameter configuration.

[0048] When the detection block 21 is pressed and moves to drive the block spring piece 22 to move until the block spring piece 22 is in a conductive state with the first conductive strip 31 and the second conductive strip 32, the first conductive strip 31 and the second conductive strip 32 are kept conductive through the block spring piece 22, so as to realize the discrimination of the jaw assembly 1 of the disposable execution component and effectively avoid the problem of repeated use.

[0049] Automatic parameter configuration for the Type II jaw assembly 1: In step (3), the conductive member 3 includes a first conductive strip 31 and a second conductive strip 32. The first conductive strip 31 and the second conductive strip 32 are respectively arranged in an extended manner along the axial direction, and the first conductive strip 31 and the second conductive strip 32 are arranged at intervals corresponding to each other along the radial direction. The first conductive strip 31 and the second conductive strip 32 are respectively laid in the configuration groove 12. The detection assembly 2 includes a detection block 21, a first reed 24 and a second reed 25. The first reed 24 and the second reed 25 are respectively arranged on the detection block 21, and the first reed 24 and the second reed 25 clamp the characteristic device 4 with the detection block 21. The first reed 24 and the second reed 25 are respectively arranged in a conductive manner with the characteristic device 4. The moving block 15 is used to cause the first reed 24 and the second reed 25 to be respectively arranged in a conductive manner with the first conductive strip 31 and the second conductive strip 32.

[0050] In this way, through the cooperation of the first conductive strip 31 and the second conductive strip 32 with the first reed 24 and the second reed 25 respectively, when the moving block 15 moves to apply a force to the detection block 21, the detection block 21 is pressed and moves to drive the first reed 24 and the second reed 25 to move, so that the first reed 24 and the second reed 25 are respectively in contact conduction with the first conductive strip 31 and the second conductive strip 32, and output electrical parameters to the stapler host 5. The stapler host 5 identifies the specification of the jaw assembly 1 according to the electrical parameters, and then automatically performs parameter configuration.

[0051] Furthermore, under the action of the first conductive strip 31 and the second conductive strip 32, when the used jaw assembly 1 is loaded into the stapler host 5 again, the first conductive strip 31 and the second conductive strip 32 are in a conductive state. The stapler host 5 immediately detects the electrical connection state of the first conductive strip 31 and the second conductive strip 32, rejects subsequent operations, and issues an alarm prompt. In this way, the jaw assembly 1 of the disposable execution component is identified, effectively avoiding the problem of repeated use.

[0052] The characteristic device 4 is a capacitive device. Based on the selected electrical parameters of the capacitive device, the specific specification of the inserted jaw assembly 1 is identified, and the parameter configuration of the corresponding jaw assembly 1 is automatically completed.

[0053] For example, the electrical parameters of the capacitive device are 1 μF, 2 μF, and 3 μF. The capacitor devices with the parameters of 1 μF, 2 μF, and 3 μF respectively correspond to three specifications of jaw assemblies 1, namely a, b, and c. After the jaw assembly 1 is clamped in place, during the operation of the stapler main body 5, the specification of the jaw assembly 1 is judged through the electrical parameters fed back by the capacitive device. When the electrical parameter is about 1 μF, it is recognized as the a-type jaw assembly 1, and the stapler main body calls the parameters corresponding to the a-type jaw assembly 1 for the surgeon to perform the operation. When the electrical parameter is about 2 μF, it is recognized as the b-type jaw assembly 1, and the stapler main body calls the control parameters corresponding to the b-type jaw assembly 1 for the surgeon to perform the operation. When the electrical parameter is about 3 μF, it is recognized as the c-type jaw assembly 1, and the stapler main body calls the control parameters corresponding to the c-type jaw assembly 1 for the surgeon to perform the operation.

[0054] The characteristic device 4 is a resistive device. Based on the selected electrical parameters of the resistive device, the specific specification of the inserted jaw assembly 1 is recognized, and the parameter configuration of the corresponding jaw assembly 1 is automatically completed.

[0055] For example, the electrical parameters of the resistive device are 1 ohm, 2 ohms, and 3 ohms. The capacitor devices with the parameters of 1 ohm, 2 ohms, and 3 ohms respectively correspond to three specifications of jaw assemblies 1, namely a, b, and c. After the jaw assembly 1 is clamped in place, during the operation of the stapler main body 5, the specification of the jaw assembly 1 is judged through the electrical parameters fed back by the resistive device. When the electrical parameter is about 1 ohm, it is recognized that the assembled jaw assembly 1 is the a-type jaw assembly 1, and the stapler main body calls the control parameters corresponding to the a-type jaw assembly 1 for the surgeon to perform the operation. When the electrical parameter is about 2 ohms, it is recognized that the assembled jaw assembly 1 is the b-type jaw assembly 1, and the stapler main body calls the control parameters corresponding to the b-type jaw assembly 1 for the surgeon to perform the operation. When the electrical parameter is about 3 ohms, it is recognized that the assembled jaw assembly 1 is the c-type jaw assembly 1, and the stapler main body calls the control parameters corresponding to the c-type jaw assembly 1 for the surgeon to perform the operation.

[0056] The characteristic device 4 is an inductive device. Based on the selected electrical parameters of the inductive device, the specific specification of the inserted jaw assembly 1 is recognized, and the parameter configuration of the corresponding jaw assembly 1 is automatically completed.

[0057] For example, the electrical parameters of the inductive devices are 1 H, 2 H, and 3 H. The capacitor devices with parameters of 1 H, 2 H, and 3 H respectively correspond to three specifications of jaw assemblies 1, namely a, b, and c. After the jaw assembly 1 is properly clamped, during the operation of the stapler main body 5, the stapler main body determines the specification of the jaw assembly 1 based on the electrical parameters fed back by the inductive device. When the electrical parameter is approximately 1 H, it is recognized that the assembled jaw assembly 1 is a type-a jaw assembly 1, and the stapler main body calls the control parameters corresponding to the type-a jaw assembly 1 for the surgeon to perform the operation. When the electrical parameter is approximately 2 H, it is recognized that the assembled jaw assembly 1 is a type-b jaw assembly 1, and the stapler main body calls the control parameters corresponding to the type-b jaw assembly 1 for the surgeon to perform the operation. When the electrical parameter is approximately 3 H, it is recognized that the assembled jaw assembly 1 is a type-c jaw assembly 1, and the stapler main body calls the control parameters corresponding to the type-c jaw assembly 1 for the surgeon to perform the operation.

[0058] An automatically configured electric stapler includes a stapler main body 5, a jaw assembly 1, and a detection assembly 2. The stapler main body 5 and the jaw assembly 1 are assembled. The jaw assembly 1 includes a jaw shell 11 and a moving block 15. The jaw shell 11 has a jaw rail that extends in the axial direction. The moving block 15 is movably arranged on the jaw rail. The stapler main body 5 outputs a firing instruction to drive the moving block 15 to move along the jaw rail. The detection assembly 2 is arranged on the jaw shell 11 and corresponds to the moving block 15. An initial distance is formed between the initial position of the moving block 15 and the detection assembly 2. The stapler main body 5 recognizes the specification of the jaw assembly 1 based on the initial distance. Alternatively, the detection assembly 2 includes a characteristic device 4, and the moving block 15 moves to make the characteristic device 4 conduct with the jaw assembly 1. The stapler main body 5 recognizes the specification of the jaw assembly 1 based on the electrical parameters of the characteristic device 4.

[0059] The above-mentioned automatic configuration electric stapler assembles the jaw assembly 1 and the stapler host 5, and then outputs a firing command through the stapler host 5 to prompt the moving block 15 to move in the axial direction. In the first automatic configuration mode, the moving block 15 moves axially to apply a force to the detection component 2 to determine the assembly position of the detection component 2. Different positions correspond to different jaw assemblies 1. The specifications of the jaw assembly 1 are identified based on the initial position of the moving block 15 and the starting distance between the detection component 2. In the second automatic configuration mode, the characteristic devices 4 with different electrical parameters correspond to different specifications of the jaw assembly 1. The moving block 15 moves axially to the detection component 2 applies a force to cause the characteristic device 4 to be turned on and transmit the electrical parameters to the stapler host 5, and the specifications of the jaw assembly 1 are identified based on the fed-back electrical parameters; in this way, the stapler host 5 causes the moving block 15 to move by outputting a firing command, thereby automatically identifying the specifications of the jaw assembly 1, thereby automatically configuring the parameters of the jaw assembly 1, without the need for the doctor to configure the parameters, thereby simplifying the doctor's surgical operation, and directly applying a force to the detection component 2 through the moving block 15, which is not easily interfered with, thereby ensuring the accuracy of the identification of the specifications of the jaw assembly 1 and the accuracy of the parameter configuration, thereby improving the safety of the operation.

[0060] During clinical use, the jaw assembly 1 is clamped on the connecting sleeve at the front end of the stapler main unit 5. After the stapler main unit 5 completes the self-check, the stapler main unit 5 can be operated. The stapler main unit 5 outputs a firing instruction during the operation. The stapler main unit 5 automatically completes the corresponding parameter configuration of the jaw assembly 1 during the operation.

[0061] The jaw shell 11 has a positioning groove, which includes an upper positioning groove 13 and a lower positioning groove 14. The upper positioning groove 13 and the lower positioning groove 14 are connected. The detection component 2 includes a block positioning pin 23. The inner end of the block positioning pin 23 is docked with the detection block 21, and the outer end of the block positioning pin 23 is embedded in the upper positioning groove 13. The moving block 15 is used to apply a force to cause the block positioning pin 23 to move along the upper positioning groove 13 to the lower positioning groove 14. When the block positioning pin 23 moves to the lower positioning groove 14, the detection component 2 is connected to the jaw component 1.

[0062] In this way, the detection block 21 is assembled and moved, which satisfies the signal feedback, facilitates the identification of the specifications of the jaw assembly 1, and further facilitates the parameter configuration.

[0063] A necking section is formed between the upper fixed groove 13 and the lower fixed groove 14, and the necking section is used to limit the block fixing pin 23 from moving along the lower fixed groove 14 to the upper fixed groove 13; in this way, the used jaw assembly 1, the detection assembly 2 and the conductive part 3 are conductive, and when the used jaw assembly 1 is installed into the stapler main unit 5 again, the stapler main unit 5 immediately detects the electrical connectivity state of the conductive part 3, refuses subsequent operations, and issues an alarm.

[0064] In this way, the jaw assembly 1 of the disposable execution component is screened, effectively avoiding the problem of repeated use.

[0065] The jaw assembly 1 includes a flexible connection piece group 16. The flexible connection piece group 16 is axially movably inserted into the jaw rail. The moving block 15 is assembled with the flexible connection piece group 16. The flexible connection piece group 16 is used to drive the moving block 15 to move synchronously along the axis. In this way, when the firing instruction is triggered, the flexible connection piece group 16 is driven to move axially, driving the movement of the moving block 15, realizing the detection of the detection component 2, realizing the specification identification of the jaw assembly 1, and thus realizing the automatic parameter configuration of the jaw assembly 1.

[0066] Automatic configuration embodiment 1: The detection component 2 includes a detection module. The jaw shell 11 has a plurality of configuration slots 12. Each configuration slot 12 is arranged at intervals along the axial direction of the jaw shell 11. The configuration slots 12 are used to assemble the detection module. The starting distances of each configuration slot 12 from the moving block 15 are arranged inconsistently. In this way, before the jaw assembly 1 leaves the factory, the detection module is assembled into one of the configuration slots 12 to complete the definition of the starting distance of the initial position between the detection module and the moving block 15.

[0067] When the detection block 21 is assembled into a certain configuration slot 12, it is determined that the jaw assembly 1 is of the corresponding specification.

[0068] The jaw assembly 1 includes a conductive member 3. The conductive member 3 is electrically connected to the stapler main body 5. The conductive member 3 extends along the axial direction and lies flat on each configuration slot 12. The detection module is electrically connected to the conductive member 3. In this way, when the moving block 15 moves to apply a force to the detection module, the detection module is brought into contact conduction with the conductive member 3, and the feedback signal is used to judge the starting distance of the initial position between the detection module and the moving block 15, so as to identify the specification of the jaw assembly 1 and then automatically complete the parameter configuration.

[0069] The conductive member 3 includes a first conductive strip 31. The first conductive strip 31 lies flat on each configuration slot 12. The detection module includes a detection block 21 and a block spring piece 22. The block spring piece 22 is arranged on the detection block 21. The configuration slot 12 is used to assemble the detection block 21. The moving block 15 is used to bring the block spring piece 22 into electrical connection with the jaw conductive strip. In this way, when the moving block 15 moves to apply a force to the detection block 21, the detection block 21 is pressed to move, driving the block spring piece 22 to move, making the block spring piece 22 in contact conduction with the conductive member 3, and the feedback signal is used to judge the starting distance of the initial position between the detection block 21 and the moving block 15, so as to identify the specification of the jaw assembly 1 and then automatically complete the parameter configuration.

[0070] The conductive member 3 includes a first conductive strip 31 and a second conductive strip 32. The first conductive strip 31 and the second conductive strip 32 are arranged at intervals corresponding to each other, and the first conductive strip 31 and the second conductive strip 32 are laid flat in each configuration groove 12. When the detection block 21 is pressed and moves to drive the block spring piece 22 to move until the block spring piece 22 is in conduction with the first conductive strip 31 and the second conductive strip 32, the first conductive strip 31 and the second conductive strip 32 are kept in conduction, so as to realize the discrimination of the jaw assembly 1 of the disposable execution component, effectively avoiding the problem of repeated use.

[0071] Automatic configuration Embodiment 2: The jaw shell 11 has a configuration groove 12 and a conductive member 3. The conductive member 3 is laid in the configuration groove 12. The detection assembly 2 includes a detection block 21. The characteristic device 4 is arranged on the detection block 21. The detection block 21 is arranged corresponding to the configuration groove 12. The moving block 15 is movable to drive the detection block 21 to be assembled into the configuration groove 12, and the moving block 15 is used to make the characteristic device 4 in conduction with the conductive member 3.

[0072] In this way, during the operation of the stapler host 5, the moving block 15 is driven to move axially until the moving block 15 moves to press the detection block 21 into the configuration groove 12. At this time, the characteristic device 4 assembled on the detection block 21 and the conductive member 3 are made to realize the feedback of electrical parameters. Then, the stapler host 5 identifies the specification of the jaw assembly 1 based on the feedback electrical parameters and automatically configures the parameters.

[0073] The conductive member 3 includes a first conductive strip 31 and a second conductive strip 32. The first conductive strip 31 and the second conductive strip 32 are respectively arranged to extend along the axial direction, and the first conductive strip 31 and the second conductive strip 32 are arranged at intervals corresponding to each other along the radial direction, and the first conductive strip 31 and the second conductive strip 32 are respectively laid in the configuration groove 12; the detection assembly 2 includes a first spring piece 24 and a second spring piece 25. The first spring piece 24 and the second spring piece 25 are respectively in conduction with the characteristic device 4, and the first spring piece 24 and the second spring piece 25 are respectively arranged corresponding to the first conductive strip 31 and the second conductive strip 32. The moving block 15 is used to make the first spring piece 24 in conduction with the first conductive strip 31 and make the second spring piece 25 in conduction with the second conductive strip 32.

[0074] In this way, through the cooperation of the first conductive strip 31 and the second conductive strip 32 with the first spring piece 24 and the second spring piece 25 respectively, when the moving block 15 moves to apply a force to the detection block 21, the detection block 21 is pressed and moves to drive the first spring piece 24 and the second spring piece 25 to move, so that the first spring piece 24 and the second spring piece 25 are respectively in contact conduction with the first conductive strip 31 and the second conductive strip 32, thereby identifying the specification of the jaw assembly 1 by electrical parameters and automatically configuring the parameters.

[0075] Furthermore, under the action of the first conductive strip 31 and the second conductive strip 32, when the used jaw assembly 1 is loaded into the stapler main body 5 again, the first conductive strip 31 and the second conductive strip 32 are in a conductive state. The stapler main body 5 immediately detects the electrical connection state of the first conductive strip 31 and the second conductive strip 32, rejects subsequent operations, and issues an alarm prompt. In this way, the jaw assembly 1 of the disposable execution component is identified, effectively avoiding the problem of repeated use.
