[0052] The exemplary embodiments will now be described more fully. However, the exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The words “or” and “or” in the specification may mean “and” or “or”. Although the terms “upper,” “lower,” “between,” etc., may be used in this specification to describe different exemplary features and elements of this application, these terms are used herein only for convenience, such as the orientation of the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this application. Although “first” or “second,” etc., are used in this specification to denote certain features, they are only for indication of function and not as a limitation on the number or importance of specific features.

[0053] This application provides a battery mounting assembly for surgical instruments, a battery pack including the assembly, and the surgical instruments themselves. The surgical instruments include an actuator, an instrument body, and a battery pack, the battery pack comprising the battery mounting assembly and a battery cell assembly. The battery mounting assembly is mounted on the instrument body and detachably connected to the battery cell assembly, for mounting the battery cell assembly to the instrument body and transmitting electrical energy from the battery cell assembly to the instrument body. The surgical instruments may be, for example, surgical staplers, and the actuator may include, for example, a staple cartridge assembly and an anvil, for suturing and cutting tissue. The surgical instruments may also be other types of surgical instruments, such as tissue cutting instruments, implant delivery instruments, clipping instruments, etc., whose actuators perform corresponding surgical actions under the power supply of the battery cell assembly.

[0054] The battery mounting assembly includes a mounting base, a first conductive element, and a second conductive element. The first and second conductive elements are mounted on the mounting base. The first conductive element includes a first positive conductive portion and a second positive conductive portion, and the second conductive element includes a first negative conductive portion and a second negative conductive portion. Both positive conductive portions of this battery mounting assembly are located on the first conductive element, and both negative conductive portions are located on the second conductive element. Each of the first and second conductive elements only needs one pin connected to the device body. The battery cell assembly can be connected to the device body through the two conductive elements to transmit electrical energy to the device body. The structure is simple, and production, assembly, and maintenance are more convenient.

[0055] When the battery cell assembly is connected to the battery mounting assembly in a first orientation, the first positive conductive portion and the first negative conductive portion are electrically connected to the positive and negative conductive portions of the battery cell assembly, respectively. When the battery cell assembly is connected to the battery mounting assembly in a second orientation, the second positive conductive portion and the second negative conductive portion are electrically connected to the positive and negative conductive portions of the battery cell assembly, respectively. Therefore, regardless of whether the battery cell assembly is connected to the battery mounting assembly in the first or second orientation, the positive and negative conductive portions of the battery cell assembly can be aligned and electrically connected to one positive and one negative conductive portion of the battery mounting assembly. During installation, there is no need to distinguish the installation direction of the battery cell assembly, avoiding equipment damage caused by incorrect installation and saving operators time and effort in determining the installation direction.

[0056] The structure of the battery mounting assembly according to a specific embodiment of this application is described in detail below with reference to the accompanying drawings. It should be understood that the drawings and the following description of the specific embodiments are not intended to limit the scope of protection of this application. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted. In this embodiment, a configuration is set... Figure 1 , 2 In the sequence 4, 5, and 9, direction S1 is the first direction. Figure 1 , 2 In 4, 5, and 9, direction S2 is the second direction. Figure 1 and Figure 9 In this context, direction S3 is a third direction. The first direction, second direction, and third direction are directions defined for the structure of the battery mounting assembly. The first direction, second direction, and third direction can be perpendicular to each other, but this application is not limited to this. Two of the first direction, second direction, and third direction can also be configured to form an acute angle or an obtuse angle as needed.

[0057] Figures 1-9 The structure of the cell assembly 1 and the battery mounting assembly 20 according to an embodiment of this application is shown. Figure 10A circuit diagram showing the connection between the cell assembly and the battery mounting assembly in this embodiment is illustrated. Figure 1 This diagram illustrates the battery cell assembly 1 in a first orientation engaging with the battery mounting assembly 20 according to this embodiment. Figure 2 A bottom view of the battery cell assembly 1 according to this embodiment is shown. The battery cell assembly 1 includes a second mounting portion 13, which is a mounting hole provided on the end face of the battery cell assembly 1. The second mounting portion 13 is provided with a positive electrode conductive portion 11 and a negative electrode conductive portion 12 of the battery cell. In this embodiment, the ends of the positive electrode conductive portion 11 and the negative electrode conductive portion 12 of the battery cell are respectively sheet-like conductive structures.

[0058] Figures 3-5 The structure of the battery mounting assembly 20 is shown. The battery mounting assembly 20 includes a mounting base 2, a first conductive element 3, and a second conductive element 4, which are mounted on the mounting base 2. The first conductive element 3 includes a first positive conductive portion 31, a first connecting portion 33, and a second positive conductive portion 32 connected in sequence. The second conductive element 4 includes a first negative conductive portion 41, a second connecting portion 43, and a second negative conductive portion 42 connected in sequence. The mounting base 2 includes a base plate 21, a first mounting portion 22, a first support 23, and a second support 24. The base plate 21 includes a first surface and a second surface facing away from each other. The second surface 212 of the base plate 21 is the surface facing the device body, and the first surface 211 of the base plate 21 is the surface that mates with the battery cell assembly 1. The first mounting portion 22, the first support 23, and the second support 24 are disposed on the first surface 211 of the base plate 21, and the first support 23 is used to fix the first positive conductive portion 31 and the first negative conductive portion 41. The second support 24 is used to fix the second positive conductive part 32 and the second negative conductive part 42. The first mounting part 22 is a protrusion protruding from the first surface 211 of the base plate 21, and the first mounting part 22 can be inserted into the second mounting part 13 of the cell assembly 1 to form an embedded connection. In this embodiment, the structure of the first mounting part 22 and the second mounting part 13 is only an example and is not intended to limit the scope of protection of this application. For example, in an alternative embodiment, the first mounting part 22 can be a mounting hole provided in the base plate 21, and the second mounting part 13 is a protrusion provided on the end face of the cell assembly 1. In another alternative embodiment, the first mounting part 22 can be provided on the side of the base plate 21, and correspondingly the second mounting part 13 is provided on the side of the cell assembly 1. In other alternative embodiments, the first mounting part 22 and the second mounting part 13 can also be connected by a snap-fit ​​method.

[0059] When the cell assembly 1 is installed with the battery mounting assembly 20, the cell assembly 1 can be inserted into the battery mounting assembly 20 in either a first or a second posture. Figure 1 This diagram shows the battery cell assembly 1 being inserted into the battery mounting assembly 20 in a first orientation. Figure 9 A schematic diagram is shown when the cell assembly 1 is inserted into the battery mounting assembly 20 in a second orientation. (See diagram below.) Figure 1 and Figure 2 As shown, when the battery cell assembly 1 is connected to the battery mounting assembly 20 in a first posture, the first support 23 is opposite to the positive conductive part 11 and the negative conductive part 12 of the battery cell. After the first mounting part 22 is inserted into the second mounting part 13, the first positive conductive part 31 and the first negative conductive part 41 are electrically connected to the positive conductive part 11 and the negative conductive part 12 of the battery cell assembly 1, respectively. Figure 2 and Figure 9 As shown, when the battery cell assembly 1 is connected to the battery mounting assembly 20 in the second posture, the second support 24 is opposite to the positive conductive part 11 and the negative conductive part 12 of the battery cell. After the first mounting part 22 is inserted into the second mounting part 13, the second positive conductive part 32 and the second negative conductive part 42 are electrically connected to the positive conductive part 11 and the negative conductive part 12 of the battery cell assembly 1, respectively. The first posture and the second posture differ by 180°. When assembling the battery cell assembly 1 into the device body, the operator does not need to distinguish between the correct and reverse insertion of the battery cell assembly 1. For example, the first posture can be used as the correct insertion method and the second posture as the reverse insertion method, or the second posture can be used as the correct insertion method and the first posture as the reverse insertion method. The operator can achieve the correct electrical connection between the battery cell assembly 1 and the battery mounting assembly 20 regardless of whether the insertion method is correct or reverse.

[0060] Therefore, by using the battery mounting assembly 20, regardless of whether the cell assembly 1 is connected to the battery mounting assembly 20 in the first or second orientation, the positive conductive part 11 and the negative conductive part 12 of the cell assembly 1 can be aligned and electrically connected to one positive conductive part and one negative conductive part of the battery mounting assembly 20. There is no need to distinguish the installation direction of the cell assembly 1 during installation, avoiding instrument damage caused by incorrect installation of the cell assembly 1, and saving the operator time and effort to distinguish the installation direction of the cell assembly 1, making the operation of surgical instruments more convenient.

[0061] like Figure 1 and Figure 2As shown, the battery cell assembly 1 has a first receiving cavity 141 on one side of the second mounting portion 13 along a first direction, and a second receiving cavity 142 on the other side. The first receiving cavity 141, the second mounting portion 13, and the second receiving cavity 142 are arranged in the first direction. The second mounting portion 13 extends along a third direction. Two second mating portions 131 extending along a third direction are provided on the inner walls of both sides of the second mounting portion 13. The first receiving cavity 141 contains a positive electrode conductive portion 11 and a negative electrode conductive portion 12 of the battery cell, and the second receiving cavity 142 is a cavity without conductive portions. The positive electrode conductive portion 11 and the negative electrode conductive portion 12 of the battery cell are arranged opposite to each other in the second direction. The first mounting portion 22 of the mounting base 2 extends along a third direction, and two first mating portions 221 extending along a third direction are provided on both sides of the first mounting portion 22. In this embodiment, the first mating part 221 is a protrusion, and the second mating part 131 is a groove. The first mating part 221 is embedded in the second mating part 131, serving as a guide and limiting element when the cell assembly 1 is inserted into the battery mounting assembly 20, and limiting the connection of the cell assembly 1 to the battery mounting assembly 20 only in a first or second posture. In other embodiments, the first mating part may also be a groove, and the second mating part may be a protrusion. The number and arrangement of the first and second mating parts can also be adjusted as needed, which is also within the scope of protection of this application. Here, the protrusion may be a continuous ridge or may include multiple spaced protrusions.

[0062] like Figures 3-5 As shown, the first support 23 and the second support 24 are respectively disposed on both sides of the first mounting portion 22 along the first direction, that is, the first support 23, the first mounting portion 22, and the second support 24 are arranged in the first direction. The first positive conductive portion 31 and the first negative conductive portion 41 are mounted on both sides of the first support 23 along the second direction, that is, the first positive conductive portion 31 and the first negative conductive portion 41 are aligned in the second direction. The second positive conductive portion 32 and the second negative conductive portion 42 are mounted on both sides of the second support 24 along the second direction, that is, the second positive conductive portion 32 and the second negative conductive portion 42 are aligned in the second direction. The first positive conductive portion 31 and the second negative conductive portion 42 are aligned in the first direction, and the second positive conductive portion 32 and the first negative conductive portion 41 are aligned in the first direction. Therefore, regardless of whether the battery cell assembly is inserted into the battery mounting assembly 20 in the first or second orientation, it can ensure that a set of positive and negative conductive parts are accurately aligned and inserted into the first receiving cavity, and electrically connected to the positive and negative conductive parts of the battery cell assembly.

[0063] like Figure 6 and Figure 8As shown, the first support 23 and the second support 24 extend along a third direction. The first positive conductive part 31, the second positive conductive part 32, the first negative conductive part 41 and the second negative conductive part 42 extend at least partially along a third direction. The first support 23 is provided with a first groove 231 on both sides. The first positive conductive part 31 includes a first bent part 311 and the first negative conductive part 41 includes a second bent part 411. The ends of the first positive conductive part 31 and the first negative conductive part 41 are embedded in the first groove 231 and can slide in the first groove 231. Therefore, the first groove 231 provides room for the elastic deformation of the first bent part 311 and the second bent part 411. The second support 24 is provided with a second groove 241 on both sides. The second positive conductive part 32 includes a third bent part 321 and the second negative conductive part 42 includes a fourth bent part 421. The ends of the second positive conductive part 32 and the second negative conductive part 42 are embedded in the second groove 241 and can slide in the second groove 241. Therefore, the second groove 241 provides room for the elastic deformation of the third bent part 321 and the fourth bent part 421.

[0064] like Figure 1 , Figure 5 and Figure 6 As shown, the two positive conductive parts on the battery mounting assembly 20 are both located on the first conductive member 3, and the two negative conductive parts are both located on the second conductive member 4. Each of the first conductive member 3 and the second conductive member 4 only needs one pin connected to the device body. The battery cell assembly 1 can be connected to the device body through these two conductive members, transmitting electrical energy to the device body. The structure is simple, and production, assembly, and maintenance are more convenient. Specifically, the first conductive member 3 further includes a first pin 34, and the second conductive member 4 further includes a second pin 44. The second pin 44 passes through a through hole 215 in the base plate 21 (shown in...). Figure 8 In the device, the first pin 34 and the second pin 44 extend relative to the base plate 21 in a direction away from the first surface 211 of the base plate 21. The first pin 34 is used to connect to the positive power input terminal of the device body, and the second pin 44 is used to connect to the negative power input terminal of the device body.

[0065] like Figures 4-8As shown, the first conductive element 3 is an integrally formed conductive sheet, and the second conductive element 4 is an integrally formed conductive sheet. However, this application is not limited to this. In other alternative embodiments of this application, the first conductive element 3 may also include multiple fixedly connected conductive segments, and / or the second conductive element 4 may also include multiple fixedly connected conductive segments. The first connecting portion 33 and the second connecting portion 43 extend along the surface of the base plate 21. A plurality of conductive part fixing members 25 are provided on the base plate 21. The first connecting portion 33 and the second connecting portion 43 are respectively provided with mounting holes. The conductive part fixing members 25 are passed through the mounting holes to fix the first connecting portion 33 and the second connecting portion 43 to the surface of the base plate 21. The first connecting portion 33 and the second connecting portion 43 cannot cross-conduct, so that the first connecting portion 33 and the second connecting portion 43 are insulated from each other, realizing the insulation isolation between the positive electrode conductive sheet and the negative electrode conductive sheet. To achieve clearance and isolation between the first connecting portion 33 and the second connecting portion 43, the first connecting portion 33 is at least partially disposed on one side of the first surface 211 of the base plate 21, and the second connecting portion 43 is at least partially disposed on one side of the first surface 211 of the base plate 21. Furthermore, a portion of one of the connecting portions 33 and 43 is disposed on one side of the second surface 212 of the base plate 21 to avoid the other connecting portion. For example, the second connecting portion 43 may be entirely disposed on one side of the first surface 211 of the base plate 21, a portion of the first connecting portion 33 may be disposed on one side of the first surface 211 of the base plate 21 to connect with the first positive conductive portion 31 and the second positive conductive portion 32, and another portion of the first connecting portion 33 may be disposed on one side of the second surface 212 of the base plate 21 to avoid the second connecting portion 43. Alternatively, the first connecting part 33 is entirely disposed on one side of the first surface 211 of the base plate 21, a portion of the second connecting part 43 is disposed on one side of the first surface 211 of the base plate 21 to connect with the first negative conductive part 41 and the second negative conductive part 42, and another portion of the second connecting part 43 is disposed on one side of the second surface 212 of the base plate 21 to avoid the first connecting part 33.

[0066] In this embodiment, the example is taken where a portion of the first connecting part 33 is located on one side of the second surface 212 of the base plate 21. Figures 4-8As shown, the base plate 21 has a first opening 213 and a second opening 214. The first connecting portion 33 includes a first extension 331, a first step 332, a second extension 333, a second step 334, and a third extension 335 connected in sequence. The first extension 331 and the third extension 335 are located on one side of the first surface 211 of the base plate 21. The first extension 331 is connected to the first positive conductive portion 31, and the third extension 335 is connected to the second positive conductive portion 32. The first step 332 and the second step 334 are respectively inserted into the first opening 213 and the second opening 214. The second extension 333 connects the first step 332 and the second step 334 and is located on one side of the second surface 212 of the base plate 21 to avoid the second connecting portion 43. Furthermore, the second extension 333 has a first corner 3331 to avoid the second connecting portion 43. The second connecting portion 43 is integrally disposed on one side of the first surface 211 of the base plate 21, and includes a fourth extension segment 431, a fifth extension segment 432, and a sixth extension segment 433 connected in sequence. The fourth extension segment 431 is connected to the first negative electrode conductive portion 41, and the sixth extension segment 433 is connected to the second negative electrode conductive portion 42. The fifth extension segment 432 is provided with a second corner 4321 to avoid the first connecting portion 33.

[0067] like Figures 4-8 As shown, the first corner 3331 of the second extension segment 333 is located at a spatially staggered position where the second extension segment 333 and the fifth extension segment 432 intersect. By setting the first corner 3331, a portion of the second extension segment 333 and the first extension segment 331 are located inside the fourth extension segment 431 (closer to the respective conductive parts). The second corner 4321 of the fifth extension segment 432 is located at a spatially staggered position where the fifth extension segment 432 and the second stage 334 intersect. By setting the second corner 4321, a portion of the fifth extension segment 432 and the sixth extension segment 433 are located inside the third extension segment 335 (closer to the respective conductive parts). In another alternative embodiment, the second corner 4321 can also be located at a spatially staggered position where the fifth extension segment 432 and the first stage 332 intersect. Figures 3-6 As shown, through the structural design of the battery mounting assembly 20 in this embodiment, the first connecting part 33 and the second connecting part 43 can occupy a small distribution area without interfering with each other, and the insulation between the first conductive element 3 and the second conductive element 4 can be better achieved by the barrier of the base plate 21 at the spatially intersecting position.

[0068] In another embodiment, the structures of the first connecting portion and the second connecting portion can also be interchanged. For example, the second connecting portion includes a first extension segment, a first step segment, a second extension segment, a second step segment, and a third extension segment connected in sequence.

[0069] Figure 10 This is a circuit diagram illustrating the interaction between the battery cell assembly and the battery mounting assembly in this embodiment. The example used here is four cells B1 to B4 within the battery cell assembly; however, in other alternative embodiments of this application, the number of cells can be adjusted as needed. The battery cell assembly has a uniform positive electrode conductive portion 11 and a negative electrode conductive portion 12 for outputting electrical energy from the battery cell assembly. In this embodiment, the multiple cells in the battery cell assembly are connected in series sequentially, with the positive electrode of the first cell leading out to the positive electrode conductive portion 11, and the negative electrode of the last cell leading out to the negative electrode conductive portion 12. The following is in conjunction with... Figure 10 Let me explain in detail the working principle of this battery mounting assembly.

[0070] Combination Figure 1 , Figure 3 , Figure 4 and Figure 10When the battery cell assembly 1 is connected to the battery mounting assembly 20 in the first posture, the first mounting part 22 enters the second mounting part 13, and the first support 23, the first positive conductive part 31, and the first negative conductive part 41 enter the first receiving cavity 141. The first bent portion 311 of the first positive conductive part 31 and the second bent portion 411 of the first negative conductive part 41 are elastically deformed by the forces of the positive conductive part 11 and the negative conductive part 12 of the battery cell, respectively. The elastic force of the first bent portion 311 and the second bent portion 411 maintains the stability of the first support 23 in the first receiving cavity 141. The first positive conductive part 31 is electrically connected to the positive conductive part 11 of the battery cell, and the first negative conductive part 41 is electrically connected to the negative conductive part 12 of the battery cell. At this time, the electrical energy of the battery cell assembly can be transmitted to the positive power supply input terminal and the negative power supply input terminal of the device body through the first pin 34 and the second pin 44. The second support 24, the second positive conductive part 32, and the second negative conductive part 42 enter the second receiving cavity 142. The third bend 321 and the fourth bend 421 of the second positive conductive part 32 and the second negative conductive part 42 undergo elastic deformation under the force of the inner wall of the second receiving cavity 142, and the elastic force of the third bend 321 and the fourth bend 421 maintains the stability of the second support 24 installed in the second receiving cavity 142.

[0071] Combination Figure 9 , Figure 3 , Figure 4 and Figure 10 When the battery cell assembly 1 is connected to the battery mounting assembly 20 in the second posture, the first mounting part 22 enters the second mounting part 13, and the first support 23, the first positive conductive part 31, and the first negative conductive part 41 enter the second receiving cavity 142. The first bending part 311 and the second bending part 411 undergo elastic deformation due to the force of the inner wall of the second receiving cavity 142. The elastic force of the first bending part 311 and the second bending part 411 maintains the stability of the first support 23 installed in the second receiving cavity 142. The second support 24, the second positive conductive part 32, and the second negative conductive part 42 enter the first receiving cavity 141. The third bending part 321 and the fourth bending part 421 undergo elastic deformation due to the force of the positive conductive part 11 and the negative conductive part 12 of the battery cell. The elastic force of the third bending part 321 and the fourth bending part 421 maintains the stability of the second support 24 installed in the first receiving cavity 141. The second positive conductive part 32 is electrically connected to the positive conductive part 11 of the battery cell, and the second negative conductive part 42 is electrically connected to the negative conductive part 12 of the battery cell. At this time, the electrical energy of the battery cell assembly can be transmitted to the positive power supply input terminal and the negative power supply input terminal of the device body through the first pin 34 and the second pin 44.
