Description

Technical Field

[0001] This utility model patent relates to the technical field of configuration parameters of electric staplers, and more specifically, to an electric stapler with automatic configuration. Background Technology

[0002] In minimally invasive abdominal surgery, staplers are increasingly used due to their advantages such as simple operation, small wound area, and fast postoperative recovery, playing an important role in promoting the development of surgical techniques. Depending on the location of the lesion, staplers need to be adapted to different specifications of actuators to perform the surgery. Usually, the surgeon selects the appropriate actuator for assembly before the operation and configures the parameters of the stapler according to the selected actuator.

[0003] Currently, to avoid affecting the surgeon's focus and prevent the surgeon from configuring the parameters of the actuator, automatic identification is used to meet the parameter configuration requirements of the actuator. For example, the prior patent with authorization publication number CN217430084U discloses an automatic identification device for the actuator component of a stapler. The stapler includes a stapler body and at least one actuator component. The stapler body includes a distal engagement portion, and the actuator component includes a proximal engagement portion that can engage with the distal engagement portion. A controller is disposed in the stapler body. The automatic identification device for the actuator component includes: at least one magnetic marker placement position disposed on the proximal engagement portion of the actuator component, where the magnetic marker can be placed; and at least one Hall sensor installed on the distal engagement portion of the stapler body. When the actuator component engages with the stapler body, the Hall sensor corresponds one-to-one with the magnetic marker placement position, so that the Hall sensor can detect whether there is a magnetic marker in the corresponding magnetic marker placement position, and / or detect the magnitude of the magnetic flux of the magnetic marker in the magnetic marker placement position, and transmit the corresponding electrical signal to the controller.

[0004] In existing technologies, the automatic identification of the execution component is achieved by matching the position of the Hall sensor with the magnetic marker. This non-contact automatic identification is susceptible to interference and factors such as the aging of the Hall sensor, which can lead to insufficient accuracy in automatic identification. This can cause the stapler to malfunction or produce incorrect operations, affecting surgical safety. Utility Model Content

[0005] The purpose of this invention is to provide an automatically configured electric stapler, aiming to solve the problem that the automatic parameter configuration of electric staplers is easily interfered with in the prior art.

[0006] This invention is implemented as follows: an automatically configured electric stapler includes a stapler main unit, a jaw assembly, and a detection component. The stapler main unit and the jaw assembly are assembled together. The jaw assembly includes a jaw shell and a moving block. The jaw shell has a jaw rail that extends axially. The moving block is movably mounted on the jaw rail. The stapler main unit outputs a firing command to drive the moving block to move along the jaw rail. The detection component is mounted on the jaw shell. The moving block and the detection component are arranged correspondingly. An initial distance is formed between the initial position of the moving block and the detection component. The stapler main unit identifies the specifications of the jaw assembly based on the initial distance. Alternatively, the detection component includes a characteristic device. The moving block moves to make the characteristic device conductive with the jaw assembly. The stapler main unit identifies the specifications of the jaw assembly based on the electrical parameters of the characteristic device.

[0007] Furthermore, the detection component includes a detection module, the jaw shell has multiple configuration slots, each configuration slot is arranged at intervals along the axial direction of the jaw shell, the configuration slots are used to assemble the detection module, and the starting distance between each configuration slot and the moving block is inconsistent.

[0008] Furthermore, the jaw assembly includes a conductive element, which is conductively arranged with the stapler host, extends along the axial direction, and is laid flat in each of the configuration slots. The detection module is conductively arranged with the conductive element.

[0009] Furthermore, the conductive component includes a clamping conductive strip, which is laid flat in each of the configuration slots. The detection module includes a detection block and a block spring, which is installed on the detection block. The configuration slots are used to assemble the detection block. The moving block is used to make the block spring and the clamping conductive strips conductively connected.

[0010] Furthermore, the jaw shell has a configuration slot and a conductive element, the conductive element being laid in the configuration slot, the detection assembly including a detection block, the characteristic device being mounted on the detection block, the detection block being arranged correspondingly to the configuration slot, the movable block being movable to drive the detection block to be assembled into the configuration slot, and the movable block being used to make the characteristic device and the conductive element being arranged in a conductive manner.

[0011] Furthermore, the conductive element includes a first conductive strip and a second conductive strip, which extend along the axial direction and are arranged at intervals along the radial direction, and are respectively laid with the configuration groove; the detection component includes a first spring and a second spring, which are respectively arranged in a conductive connection with the characteristic device, and are respectively arranged in a corresponding connection with the first conductive strip and the second conductive strip; the moving block is used to make the first spring connect with the first conductive strip and to make the second spring connect with the second conductive strip.

[0012] Furthermore, the characteristic device is a capacitive device, or a resistive device, or an inductive device.

[0013] Furthermore, the jaw housing has a positioning groove, which includes an upper positioning groove and a lower positioning groove, and the upper positioning groove and the lower positioning groove are arranged in communication. The detection component includes a block pin, the inner end of which is arranged to dock with the detection block, and the outer end of which is embedded in the upper positioning groove. The moving block is used to apply a force to cause the block pin to move along the upper positioning groove to the lower positioning groove. When the block pin moves to the lower positioning groove, the detection component and the jaw assembly are in communication.

[0014] Furthermore, a narrowing section is formed between the upper fixed groove and the lower fixed groove, and the narrowing section is used to restrict the block pin from moving along the lower fixed groove to the upper fixed groove.

The moving block and the flexible connecting piece group are assembled together, and the flexible connecting piece group is used to drive the moving block to move synchronously along the axial direction.

[0016] Compared with existing technologies, the automatic configuration electric stapler provided by this utility model assembles the jaw assembly with the stapler main unit. The main unit then outputs a firing command to cause the moving block to move axially. In one automatic configuration method, the axial movement of the moving block applies force to the detection component, determining its assembly position. Different positions correspond to different jaw assemblies, and the jaw assembly specifications are identified based on the initial distance between the moving block and the detection component. In another automatic configuration method, different electrical parameter characteristic devices correspond to different jaw assembly specifications. The axial movement of the moving block applies force to the detection component, causing the characteristic device to conduct and transmit electrical parameters to the stapler main unit. The jaw assembly specifications are identified based on the feedback electrical parameters. Thus, the stapler main unit automatically identifies the jaw assembly specifications by outputting a firing command to move the moving block, thereby achieving automatic configuration of the jaw assembly parameters. This eliminates the need for manual parameter configuration by the surgeon, simplifying the surgical procedure. Furthermore, the direct application of force to the detection component by the moving block is less susceptible to interference, ensuring accurate identification of the jaw assembly specifications and accurate parameter configuration, thus improving surgical safety.

[0025] Reference Figure 1-5 The image shown is a preferred embodiment of the present invention.

[0026] An automatically configured electric stapler includes a stapler main unit 5, a jaw assembly 1, and a detection component 2. The stapler main unit 5 and the jaw assembly 1 are assembled together. The jaw assembly 1 includes a jaw housing 11 and a moving block 15. The jaw housing 11 has a jaw rail that extends axially. The moving block 15 is movably mounted on the jaw rail. The stapler main unit 5 outputs a firing command to drive the moving block 15 to move along the jaw rail. The detection component 2 is mounted on the jaw housing 11. The moving block 15 is arranged correspondingly to the detection component 2. An initial distance is formed between the initial position of the moving block 15 and the detection component 2. The stapler main unit 5 identifies the specifications of the jaw assembly 1 based on the initial distance. Alternatively, the detection component 2 includes a characteristic device 4. The moving block 15 moves to make the characteristic device 4 conductive with the jaw assembly 1. The stapler main unit 5 identifies the specifications of the jaw assembly 1 based on the electrical parameters of the characteristic device 4.

[0027] The aforementioned automatically configured electric stapler assembles the jaw assembly 1 with the stapler main unit 5. The main unit 5 then outputs a firing command, causing the moving block 15 to move axially. In automatic configuration mode one, the axial movement of the moving block 15 applies a force to the detection component 2, determining its assembly position. Different positions correspond to different jaw assemblies 1, and the specifications of the jaw assembly 1 are identified based on the initial distance between the moving block 15 and the detection component 2. In automatic configuration mode two, different electrical parameters of the characteristic device 4 correspond to different jaw assembly 1 specifications. The axial movement of the moving block 15 applies a force to the detection component 2. The force applied causes the characteristic device 4 to become conductive and transmits electrical parameters to the stapler host 5. Based on the feedback of electrical parameters, the specifications of the jaw assembly 1 are identified. In this way, the stapler host 5 outputs a firing command to cause the moving block 15 to move, thereby automatically identifying the specifications of the jaw assembly 1 and automatically configuring the parameters of the jaw assembly 1. This eliminates the need for the doctor to configure the parameters, simplifying the doctor's surgical operation. Furthermore, by applying force directly to the detection component 2 through the moving block 15, it is less susceptible to interference, ensuring the accuracy of the identification of the specifications of the jaw assembly 1 and the accuracy of the parameter configuration, thus improving the safety of the surgery.

[0028] In clinical use, the jaw assembly 1 is mounted on the connecting sleeve at the front end of the stapler main unit 5. After the stapler main unit 5 completes its self-test, the operation can be performed on the stapler main unit 5. During the operation, the stapler main unit 5 outputs a firing command and automatically completes the corresponding parameter configuration of the jaw assembly 1.

[0029] The jaw housing 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 arranged in communication. The detection component 2 includes a block pin 23. The inner end of the block pin 23 is arranged to mate with the detection block 21. The outer end of the block pin 23 is embedded in the upper positioning groove 13. The moving block 15 is used to apply force to move the block pin 23 along the upper positioning groove 13 to the lower positioning groove 14. When the block pin 23 moves to the lower positioning groove 14, the detection component 2 and the jaw assembly 1 are in communication.

[0030] In this way, the assembly of the detection block 21 is realized, and at the same time, the movement of the detection block 21 is realized, which satisfies the signal feedback, facilitates the identification of the specifications of the jaw assembly 1, and thus facilitates parameter configuration.

[0031] A narrowing section is formed between the upper fixed groove 13 and the lower fixed groove 14. The narrowing section is used to restrict the block 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 element 3 are in a conductive state. When the used jaw assembly 1 is re-inserted into the stapler host 5, the stapler host 5 immediately detects the electrical connection state of the conductive element 3, refuses subsequent operation, and issues an alarm prompt.

[0032] In this way, the jaw assembly 1 of the disposable execution component is identified, effectively avoiding the problem of reuse.

[0033] The jaw assembly 1 includes a flexible connecting piece group 16, which is axially movably inserted into the jaw rail. The moving block 15 is assembled with the flexible connecting piece group 16. The flexible connecting piece group 16 is used to drive the moving block 15 to move synchronously along the axial direction. Thus, when the firing command is triggered, the flexible connecting piece group 16 is driven to move along the axial direction, thereby moving the moving block 15 to detect the detection component 2, identify the specifications of the jaw assembly 1, and automatically configure the parameters of the jaw assembly 1.

[0034] Automatic configuration example 1:

[0035] The detection component 2 includes a detection module. The jaw housing 11 has multiple configuration slots 12, which are arranged at intervals along the axial direction of the jaw housing 11. The configuration slots 12 are used to assemble the detection module. The starting distance between each configuration slot 12 and the moving block 15 is not consistent. In this way, before the jaw component 1 leaves the factory, the detection module is assembled into one of the configuration slots 12, thus defining the starting distance between the detection module and the moving block 15.

[0036] The detection block 21 is assembled into a certain configuration slot 12, which determines that the jaw assembly 1 is of the corresponding specification.

[0037] The jaw assembly 1 includes a conductive element 3, which is conductively connected to the stapler host 5. The conductive element 3 extends along the axial direction and is laid flat in each configuration slot 12. The detection module is conductively connected to the conductive element 3. Thus, when the moving block 15 moves and applies force to the detection module, the detection module and the conductive element 3 come into contact and become conductive. The stapler host records the current travel data as the starting distance. The feedback signal triggers the stapler host to judge the starting distance between the detection module and the moving block 15, thereby identifying the specifications of the jaw assembly 1 and automatically completing the parameter configuration.

[0038] The conductive component 3 includes a clamping conductive strip, which is laid flat in each configuration slot 12. The detection module includes a detection block 21 and a block spring 22. The block spring 22 is installed on the detection block 21. The configuration slot 12 is used to assemble the detection block 21. The moving block 15 is used to make the block spring 22 and the clamping conductive strip in a conductive arrangement. In this way, when the moving block 15 moves and applies a force to the detection block 21, the detection block 21 is pressed and moves, which drives the block spring 22 to move, so that the block spring 22 and the conductive component 3 come into contact and conduct. The stapler host records the current stroke data as the starting distance. The feedback signal triggers the stapler host to judge the starting distance between the detection block 21 and the moving block 15, thereby identifying the specifications of the jaw assembly 1 and then automatically completing the parameter configuration. The conductive component 3 includes two clamping conductive strips, which are arranged at intervals and laid flat in each configuration slot 12. When the detection block 21 is pressed and moves, it drives the block spring 22 to move until the block spring 22 is in contact with the two clamping conductive strips, so that the two clamping conductive strips remain in contact, thereby realizing the identification of the jaw assembly 1 of the disposable execution component and effectively avoiding the problem of reuse.

[0039] Automatic configuration example 2:

[0040] The jaw housing 11 has a configuration slot 12 and a conductive element 3. The conductive element 3 is laid in the configuration slot 12. The detection assembly 2 includes a detection block 21. The characteristic device 4 is installed on the detection block 21. The detection block 21 and the configuration slot 12 are arranged in a corresponding manner. The moving block 15 is movable to drive the detection block 21 to be assembled into the configuration slot 12. The moving block 15 is also used to make the characteristic device 4 and the conductive element 3 in a conductive arrangement.

[0041] In this way, during the operation, the stapler host 5 drives the moving block 15 to move axially until the moving block 15 moves and presses the detection block 21 to the configuration slot 12. At this time, the characteristic device 4 and the conductive part 3 assembled on the detection block 21 realize the feedback of electrical parameters. Then, the stapler host 5 identifies the specifications of the jaw assembly 1 based on the feedback electrical parameters and automatically configures the parameters.

[0042] The conductive component 3 includes a first conductive strip and a second conductive strip, which are arranged to extend along the axial direction and are arranged at intervals along the radial direction. The first conductive strip and the second conductive strip are respectively provided with a configuration groove 12. The detection component 2 includes a first spring 24 and a second spring 25, which are arranged to conduct with the characteristic device 4 and are arranged to correspond with the first conductive strip and the second conductive strip, respectively. The moving block 15 is used to make the first spring 24 conduct with the first conductive strip and to make the second spring 25 conduct with the second conductive strip.

[0043] In this way, through the cooperation of the first conductive strip and the second conductive strip with the first spring 24 and the second spring 25 respectively, when the moving block 15 moves to apply force to the detection block 21, the detection block 21 is pressed and moves, causing the first spring 24 and the second spring 25 to move, so that the first spring 24 and the second spring 25 respectively make contact with the first conductive strip and the second conductive strip, thereby identifying the specifications of the jaw assembly 1 by electrical parameters and automatically configuring the parameters.

[0044] Furthermore, under the action of the first and second conductive strips, when the used jaw assembly 1 is re-inserted into the stapler host 5, the first and second conductive strips are in a conductive state. The stapler host 5 immediately detects the electrical connection between the first and second conductive strips, refuses subsequent operations, and issues an alarm. In this way, the jaw assembly 1 of the disposable execution component is identified, effectively avoiding the problem of reuse.

[0045] Feature device 4 is a capacitive device. Based on the selected electrical parameters of the capacitive device, the specific specifications of the inserted jaw assembly 1 are identified, and the parameter configuration of the corresponding jaw assembly 1 is automatically completed.

[0046] For example, the electrical parameters of the capacitive devices are 1uf, 2uf, and 3uf. These parameters correspond to three types of jaw assembly 1: a, b, and c, respectively. After the jaw assembly 1 is installed, the stapler main unit 5 determines the specification of the jaw assembly 1 based on the electrical parameters fed back by the capacitive devices during operation. When the electrical parameter is approximately 1uf, it is identified as type a jaw assembly 1, and the stapler main unit uses the corresponding parameters for type a jaw assembly 1 for the surgeon to perform the operation. When the electrical parameter is approximately 2uf, it is identified as type b jaw assembly 1, and the stapler main unit uses the corresponding control parameters for type b jaw assembly 1 for the surgeon to perform the operation. When the electrical parameter is approximately 3uf, it is identified as type c jaw assembly 1, and the stapler main unit uses the corresponding control parameters for type c jaw assembly 1 for the surgeon to perform the operation.

[0047] Feature device 4 is a resistive device. Based on the selected electrical parameters of the resistive device, the specific specifications of the inserted jaw assembly 1 are identified, and the parameter configuration of the corresponding jaw assembly 1 is automatically completed.

[0048] For example, the resistive device has electrical parameters of 1 ohm, 2 ohms, and 3 ohms. Capacitors with parameters of 1 ohm, 2 ohms, and 3 ohms correspond to three types of jaw assembly 1, namely a, b, and c, respectively. After the jaw assembly 1 is installed, the stapler main unit 5 determines the specification of the jaw assembly 1 based on the electrical parameters fed back by the resistive device during operation. When the electrical parameter is approximately 1 ohm, the assembled jaw assembly 1 is identified as type a jaw assembly 1, and the stapler main unit calls the corresponding control parameters for type a jaw assembly 1 for the surgeon to perform the operation. When the electrical parameter is approximately 2 ohms, the assembled jaw assembly 1 is identified as type b jaw assembly 1, and the stapler main unit calls the corresponding control parameters for type b jaw assembly 1 for the surgeon to perform the operation. When the electrical parameter is approximately 3 ohms, the assembled jaw assembly 1 is identified as type c jaw assembly 1, and the stapler main unit calls the corresponding control parameters for type c jaw assembly 1 for the surgeon to perform the operation.

[0049] Feature device 4 is an inductive device. Based on the selected electrical parameters of the inductive device, the specific specifications of the inserted jaw assembly 1 are identified, and the parameter configuration of the corresponding jaw assembly 1 is automatically completed.

[0050] For example, the inductive device has electrical parameters of 1 H, 2 H, and 3 H. The capacitors with parameters of 1 H, 2 H, and 3 H correspond to three types of jaw assemblies 13, namely a, b, and c, respectively. After the jaw assembly 13 is installed, the stapler main unit 5 determines the specification of the jaw assembly 1 through the electrical parameters fed back by the inductive device during the operation. When the electrical parameter is approximately 1 H, it is identified that the assembled jaw assembly 1 is a type a jaw assembly 1, and the stapler main unit 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 identified that the assembled jaw assembly 1 is a type b jaw assembly 1, and the stapler main unit 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 identified that the assembled jaw assembly 1 is a type c jaw assembly 1, and the stapler main unit calls the control parameters corresponding to the type c jaw assembly 13 for the surgeon to perform the operation.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
