Description

Technical Field

[0001] This disclosure relates to a stapler and its operating and execution components. Background Technology

[0002] A surgical stapler is a medical device used to close surgical incisions, replacing traditional manual suturing. It is applied in cardiothoracic surgery, gastrointestinal surgery, hepatobiliary and pancreatic surgery, general surgery, and urology. With the development of minimally invasive surgical techniques, staplers can help patients reduce pain and accelerate wound healing. Staplers offer advantages such as ease of use, rapid suturing, simple operation, and reduced side effects and surgical complications. Staplers include manual and electric types. Based on their application, staplers can be categorized as linear staplers, circular staplers, laparoscopic staplers, and skin staplers.

[0003] A stapler typically consists of two parts: an actuating component, which performs surgical operations such as cutting and suturing; and an operating component, which engages distally with the actuating component and may have a handle or grip proximally. Various types of actuating components can be provided to meet different surgical requirements (for example, laparoscopic staplers include multiple actuating components to accommodate different suture lengths), and the operating component can engage with various types of actuating components. During surgery, the actuating component can be replaced as needed without replacing the operating component, allowing the operating component to be reused multiple times. This reduces the cost of using the stapler.

[0004] Different types of actuators have different cutting and suture lengths. Using the wrong actuator with the operating component can lead to instrument damage and / or medical accidents. Therefore, it is essential to correctly identify the type of actuator to prevent incorrect engagement. Furthermore, in the case of an electric stapler, relevant information about the actuator (e.g., its type) must be transmitted to the control unit in the operating component. This allows the appropriate operating mode to be selected based on the actuator type to ensure correct closure and firing operations, thus preventing medical accidents. Summary of the Invention

[0005] The purpose of this disclosure is to solve the above-mentioned technical problems and to provide a stapler and its operating component and execution component, wherein the operating component can automatically identify the type of the execution component when the execution component is engaged with the operating component and thus select the operating mode corresponding to that type of execution component to operate the execution component.

[0006] Another object of this disclosure is to provide a stapler and its operating and execution components, which can easily convert an existing stapler into a stapler according to this disclosure.

[0007] Another object of this disclosure is to provide an anastomosis device and its operating and execution components, which can automatically identify different types of execution components with a simple structure and low cost.

[0008] According to a first aspect of this disclosure, a stapler is provided, the stapler including an operating component and at least one actuating component, wherein a distal engagement portion of the operating component and a proximal engagement portion of the actuating component are capable of engaging and thus overlapping each other, characterized in that the stapler further includes an actuating component identification device, the actuating component identification device including a conductive electrode disposed on the distal engagement portion of the operating component and electrically connected to a power source and a conductive medium disposed on the proximal engagement portion of the actuating component, wherein when the actuating component engages with the operating component, at least one conductive electrode is capable of aligning with and energizing at least one conductive medium to generate an electrical signal, the electrical signal being capable of being transmitted to a controller located in the operating component.

[0009] Therefore, when the operating component of the anastomosis device engages with at least one actuating component, a corresponding electrical signal is generated if the conductive electrode is aligned and connected to at least one conductive medium. This electrical signal can be transmitted to the controller located in the operating component. The controller can then automatically identify the type of the engaged actuating component based on this electrical signal and operate the actuating component accordingly. If no conductive medium is aligned and connected to either conductive electrode, no electrical signal is generated, and therefore the operating component will not operate the actuating component. Thus, incorrect identification of the actuating component and / or erroneous operation of the actuating component can be prevented.

[0010] Preferably, the distal engagement portion of the operating component is constructed as a sleeve, and the proximal engagement portion of the actuating component is constructed as a connecting rod; correspondingly, a conductive electrode is disposed in the wall of the sleeve, and a conductive medium is disposed on the circumference of the connecting rod. This allows for a simple method of engaging the operating component and the actuating component, as well as aligning and connecting the conductive electrode and the conductive medium.

[0011] Preferably, the conductive electrode is constructed as a pin, which includes a cylindrical housing, a ball disposed within the inner cavity of the cylindrical housing, and a biasing element. The biasing element biases the ball so that the ball remains in contact with the actuating component when the operating component engages with the actuating component. This provides a simple way to implement the conductive electrode and ensure contact between the conductive electrode and the actuating component.

[0012] Preferably, the conductive medium comprises a conductive coating or conductive tape, or the conductive medium is constructed as a conductive coating or conductive tape. This allows for a simple implementation of the conductive medium.

[0013] Preferably, the conductive coating is a conductive paint, particularly a conductive paint composed of inorganic silver powder. Inorganic silver powder has good conductivity and printability, and also exhibits high hardness while maintaining excellent adhesion. This makes the conductive medium less prone to wear.

[0014] Preferably, the conductive medium extends around the entire circumference of the insert rod and preferably forms a closed ring, or the conductive medium extends around a portion of the circumference of the insert rod and preferably forms a ring with a notch. This allows for the simple application of the conductive medium. Furthermore, it allows for more flexible arrangement of the conductive electrodes.

[0015] Preferably, the conductive electrodes are connected to the controller via a circuit board, preferably a flexible circuit board, so that the electrical signals can be transmitted to the controller via the circuit board. This simplifies the installation of the conductive electrodes and the transmission of electrical signals. Furthermore, it facilitates the simplification of retrofitting existing staplers.

[0016] Preferably, the width of the conductive medium is greater than the width of the conductive electrode. This facilitates the alignment and contact between the conductive medium and the conductive electrode.

[0017] Preferably, the anastomosis device includes multiple different actuation components, each with a different number-position combination of conductive media. This generates different electrical signals and thus distinguishes the type of each actuation component.

[0018] Preferably, the maximum number of conductive media in each actuating component is less than or equal to the number of conductive electrodes in the operating component, and the corresponding conductive media of each actuating component is positioned such that when the actuating component is engaged with the operating component, each corresponding conductive media can be aligned with a conductive electrode.

[0019] Preferably, the stapler includes three different actuation components: a first actuation component has two conductive media that are offset from each other; a second actuation component has one conductive media; and a third actuation component has one conductive media. The positions of the conductive media of the second actuation component on the proximal joint portion and the positions of the conductive media of the third actuation component on the proximal joint portion are offset from each other.

[0020] Preferably, the operating component includes a handle, and the power supply is built into the handle.

[0021] Preferably, the controller selects an operating mode based on the electrical signal and operates the execution component according to the selected operating mode.

[0022] According to a second aspect of this disclosure, an operating component for an anastomosis device according to this disclosure is provided, the operating component having a distal engagement portion capable of engaging a proximal engagement portion of an actuating component, a power-connected conductive electrode disposed on the distal engagement portion of the operating component, and a controller.

[0023] According to a third aspect of this disclosure, an execution component for an anastomosis device according to this disclosure is provided, the execution component having a proximal engagement portion capable of engaging a distal engagement portion of an operating component and a conductive medium disposed on the proximal engagement portion of the execution component.

[0024] The operating components of the second aspect and the execution components of the third aspect of this disclosure also bring the same advantages as the stapler of the first aspect of this disclosure, which will not be repeated here.

[0025] The anastomosis device and its operating and execution components according to this disclosure can automatically identify the type of execution component when the execution component engages with the operating component with a simple structure and low cost, thereby avoiding misoperation, and can easily modify existing execution and operating components.

[0032] Figure 6A and Figure 6B Show respectively Figures 1 to 3 Enlarged view and cross-sectional view of the conductive electrodes of the operating components. Detailed Implementation

[0033] Figure 1A stapler 1 according to an embodiment of the present disclosure is shown. In this embodiment, the stapler 1 is configured as a laparoscopic stapler. However, it is understood that the execution component identification device according to the present disclosure is not limited to use in... Figure 1 The laparoscopic anastomosis device shown is not applicable to any anastomosis device with replaceable actuation components.

[0034] like Figure 1 As shown, the stapler 1 may include an actuation component 2 and an operation component 3. The operation component 3 may engage with the actuation component 2 to operate the actuation component 2. The operation component 3 may include a handle 4 or grip near the proximal side for the user to operate the component 3. The handle 4 may include a trigger so that the user can trigger the actuation component 2 to perform actions such as cutting or suturing. In addition, the stapler 1 may include a power source, which may be built into the handle 4 or located at other locations on the operation component 3. Alternatively, the stapler 1 may be electrically connected to an external power source to be powered by that external power source. Furthermore, the stapler 1 may also include a controller configured to select different operating modes to operate the actuation component according to the type of the actuation component. The controller is preferably located in the operation component 3.

[0035] Figure 2 Show Figure 1 A schematic diagram of a partial cross-section of the stapler 1. Figure 3 Shown in Figure 2 An enlarged view of portion III of the anastomosis device 1 circled in the center. The distal engagement portion 31 of the operating component 3 and the proximal engagement portion 21 of the actuating component 2 can engage with each other and thus overlap each other. In a preferred embodiment, the distal engagement portion 31 of the operating component 3 can be configured as a sleeve, while the proximal engagement portion 21 of the actuating component 2 can be configured as a fitting rod, such that the fitting rod of the actuating component 2 can be fitted into the sleeve of the operating component 3.

[0036] The stapler 1 may include an actuator identification device 5 according to the present disclosure. The actuator identification device 5 may include a conductive electrode 51 electrically connected to a power source, disposed on the distal engagement portion 31 of the operating component 3, and a conductive medium 52 disposed on the proximal engagement portion 21 of the actuator 2. When the actuator 2 engages with the operating component 3, at least one conductive electrode 51 can align with and connect to at least one conductive medium 52 to generate an electrical signal, which can be transmitted to a controller located in the operating component 3. Thus, the controller can select a corresponding operating mode based on the electrical signal to operate the actuator 2 according to the selected operating mode. Furthermore, the width of the conductive medium 52 is preferably greater than the maximum width of the conductive electrode 51 to ensure that the conductive medium 52 and the conductive electrode 51 can be aligned and contact each other.

[0037] Figure 4A , 4B 4C and 4C respectively show Figures 1 to 3 The image shows a perspective view and two side views of the execution component 2. The execution component 2 may include a proximal engagement portion 21 capable of engaging with the distal engagement portion 31 of the operation component 3, and an end effector 22. The end effector 22 may include a staple cartridge 221 and an anvil 222. The anvil 222 and the staple cartridge 221 are pivotally closed to clamp human tissue between them, for example, to perform cutting and suturing.

[0038] According to the present disclosure, the conductive medium 52 on the actuator side of the actuator component identification device 5 may be located on the proximal engagement portion 21 of the actuator component 2. In a preferred embodiment, the conductive medium 52 may include a conductive coating or conductive tape, or may be composed of a conductive coating or conductive tape. The conductive coating may be configured as a conductive paint, particularly a conductive paint composed of inorganic silver powder. When the proximal engagement portion 21 of the actuator component 2 is configured as a snap-fit ​​rod, the conductive medium 52 may extend around the entire circumference of the snap-fit ​​rod and preferably form a closed ring. Alternatively, the conductive medium 52 may extend around a portion of the circumference of the snap-fit ​​rod and preferably form a ring with a notch, such as... Figure 4B As shown. The conductive medium 52 can be arbitrarily arranged within the range of the proximal engagement portion 21 of the actuator 2, as long as it does not affect the engagement between the proximal engagement portion 21 of the actuator 2 and the distal engagement portion 31 of the operating component 3.

[0039] To distinguish different types of actuators, different actuators may have different quantities and / or locations, or different combinations of quantity-location, of conductive medium 52. Figure 5A , Figure 5B and Figure 5C Enlarged views of the proximal engagement portion 21 of different types of execution components 2 are shown respectively. Figure 5C Execution component 2 and Figures 4A to 4C Corresponding to the execution component 2, the execution component 2 has two conductive media 52. The positions of the two conductive media 52 on the proximal junction portion 21 are offset from each other. Figure 5A and Figure 5B The execution components 2' and 2" each have a conductive medium 52, but are arranged at different positions near the joint portion 21. Figure 5A The conductive medium 52 has a right-side conductive medium 52 that is relatively close to the engagement end of the actuator 2'. Figure 5B The conductive medium 52 has a left-side conductive medium 52 that is relatively far from the engagement end of the actuator 2". In other words, Figure 5A A conductive dielectric 52 than Figure 5B A conductive medium 52 is closer to the engagement end of the corresponding actuator. Figures 5A to 5C The conductive coatings of the three different actuators shown are listed in Table 1.

[0040] Table 1

[0041]

[0042] Of course, if no conductive medium is provided on the execution component, then the execution component is not a compatible execution component with the operating component 3 of the connector 1, and therefore, even if the execution component is engaged with the operating component 3, it cannot be operated. Furthermore, it is conceivable that three conductive media can be provided, such that the first execution component can have first and second conductive media, the second execution component can have second and third conductive media, and the third execution component can have first, second, and third conductive media. In this case, a fourth execution component can also exist, which has first and third conductive media. That is, if there are four or more different execution components, a greater number of conductive media can be provided, such that the quantity and position combination of the conductive media of each execution component is different.

[0043] See back Figure 3 The diagram shows a cross-sectional view of the proximal engagement portion 21 of the actuating component 2 and the distal engagement portion 31 of the operating component 3, with the actuating component 2 and the operating component 3 engaged. The operating component 3 includes a distal engagement portion 31 that can engage with the proximal engagement portion 21 of the actuating component 2.

[0044] According to this disclosure, the conductive electrode 51 on the operating component side of the actuator identification device 5 can be located on the distal engagement portion 31 of the operating component 3. Furthermore, the conductive electrode 51 can advantageously be made of metal. Preferably, the number of conductive electrodes 51 can be greater than or equal to the maximum number of conductive media 52 that may be disposed on the actuator 2. For example, in Figures 5A to 5C In this embodiment, a maximum of two conductive media 52 are provided on the proximal engagement portion 21 of the actuation component 2, thereby providing two corresponding conductive electrodes 51 on the distal engagement portion 31 of the operation component 3, and the positions of the two conductive electrodes 51 are aligned with the positions of the two conductive media 52. In other words, the corresponding conductive media 52 of each actuation component 2 can be positioned such that when the actuation component 2 is engaged with the operation component 3, each corresponding conductive media 52 can be aligned with a conductive electrode 51. Therefore, when the actuation component 2 is engaged with the operation component 3, at least one conductive media 52 can be aligned with the conductive electrode 51 and connected to generate an electrical signal.

[0045] Therefore, the generated electrical signal is related to the quantity-position combination of the conductive medium 52, thereby enabling the type of the actuator to be determined based on the correspondence between the generated electrical signal and the actuator (see Table 2).

[0046] Table 2

[0047]

[0048] After generating an electrical signal representing the type of the actuator, the electrical signal is transmitted to the controller of the stapler 1, so that the controller can determine the type of the actuator based on the electrical signal and select a matching operating mode, so that the controller can operate the actuator in the corresponding operating mode and thus the actuator can perform corresponding cutting and / or suturing actions.

[0049] When the distal engagement portion 31 of the operating component 3 is configured as a sleeve, the conductive electrode 51 may be disposed in the wall of the sleeve. Figure 6A and Figure 6B Show respectively Figures 1 to 3 A perspective view and a cross-sectional view of a preferred embodiment of the conductive electrode 51 of the operating component 3. The conductive electrode 51 can be configured as a push pin. The push pin may include a cylindrical housing 511 and a ball 512 and a biasing element, particularly a spring 513, arranged within the cylindrical housing 511. The cylindrical housing 511 is preferably cylindrical. The diameter of the ball 512 may be slightly larger than the maximum inner diameter at the opening of the cylindrical housing 511, preventing the ball 512 from leaving the cylindrical housing 511. The height of the cylindrical housing 511 may be dimensionally designed such that the ball 512 can make good contact with the conductive medium 52 when the operating component 3 engages with the actuating component 2. The spring 513 can bias the ball 512, keeping the ball 512 in contact with the actuating component 2 when the operating component 3 engages with the actuating component 2. Accordingly, a rounded portion may be provided on the engagement end face of the proximal engagement portion 21 of the actuating component 2 (see, for example, [reference needed]). Figures 5A to 5C The rounded portion 211 in the middle is used to make the ball 512 easy to retract during the engagement of the operating component 3 and the actuating component 2.

[0050] Return again Figure 3 The conductive electrode 51 can be fixed to the circuit board 32, for example, by soldering. The conductive electrode 51 can be connected to the controller via the circuit board 32, so that the generated electrical signal can be transmitted to the controller via the circuit board 32. The conductive electrode 51 can be mounted on the distal end of the circuit board 32. The proximal end (not shown) of the circuit board 32 can be directly or indirectly connected to the controller, thereby enabling the generation of electrical signals to be transmitted to the controller.

[0051] When the distal engagement portion 31 of the operating component 3 is constructed as a sleeve, a groove can be provided in the wall of the sleeve to house the circuit board 32. Alternatively, a cover plate can be provided to cover the circuit board 32 and protect it. The shape and position of the groove can be designed according to the geometry of the operating component 3, ensuring that the groove does not interfere with other components in the operating component 3, while also facilitating the retrofitting of existing operating components 3.

[0052] Preferably, a flexible circuit board (FPC) can be used as the circuit board 32. A flexible circuit board (FPC) has good bending properties, thus forming a bendable flexible circuit, also known as a flexible circuit board or a flexible circuit board. Therefore, the circuit board 32, implemented as a flexible circuit board, can adapt well to the shape of the operating component, has good shape adaptability, which facilitates the installation of the circuit board 32 in the operating component 3, and thus facilitates the modification of the existing operating component 3.

[0053] In addition to using circuit board 32 to mount conductive electrode 51, it is also conceivable that conductive electrode 51 can be mounted directly or through appropriate electrical components in operating component 3, and / or the generated electrical signals can be wirelessly transmitted to controller.

[0054] The controller can be implemented as any type of computing device, computing circuit, or any type of processor or processing circuit capable of executing a series of instructions stored in memory. The controller may include multiple processors and / or a multi-core central processing unit (CPU) and may include any type of processor, such as a microprocessor, digital signal processor, microcontroller, etc. The controller may also include memory to store data and / or algorithms for executing a series of instructions. The controller may also be implemented as a computer program product or software product.
