[0052] Example embodiments will now be described more fully. However, the example embodiments can be implemented in various 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 example embodiments to those skilled in the art. The "or" or "either...or" in the specification may both mean "and" or "or". Although terms such as "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, for example, according to the directions of the examples described in the drawings. Nothing in this specification should be construed as requiring a specific three-dimensional direction of the structure to fall within the scope of this application. Although terms such as "first" or "second" etc. are used in this specification to represent certain features, they are only for representational purposes and do not limit the quantity and importance of the specific features.

[0053] This application provides a battery mounting assembly for a surgical instrument, a battery pack including the same, and a surgical instrument. The surgical instrument includes an actuating mechanism, an instrument body, and a battery pack. The battery pack includes a battery mounting assembly and a battery cell assembly. The battery mounting assembly is mounted on the instrument body and is detachably connected to the battery cell assembly for mounting the battery cell assembly to the instrument body and transmitting the electrical energy of the battery cell assembly to the instrument body. The surgical instrument is, for example, a surgical stapler, and the actuating mechanism includes, for example, a staple cartridge assembly and an anvil for suturing and cutting tissue. The surgical instrument can also be other types of surgical instruments, such as tissue cutting instruments, implant pushing instruments, clip applying instruments, etc., and their actuating mechanisms perform corresponding surgical operation actions under the power supply of the battery cell assembly.

[0054] The battery mounting assembly includes a mounting base, a first conductive member, and a second conductive member. The first conductive member and the second conductive member are mounted on the mounting base. The first conductive member includes a first positive electrode conductive portion and a second positive electrode conductive portion, and the second conductive member includes a first negative electrode conductive portion and a second negative electrode conductive portion. Both positive electrode conductive portions on the battery mounting assembly are provided on the first conductive member, and both negative electrode conductive portions are provided on the second conductive member. The first conductive member and the second conductive member only need to be provided with one pin connected to the instrument body respectively. Through the two conductive members, the battery cell assembly can be connected to the instrument body to transmit electric energy to the instrument 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 posture, the first positive electrode conductive portion and the first negative electrode conductive portion are electrically connected to the positive electrode conductive portion and the negative electrode conductive portion of the battery cell of the battery cell assembly respectively. When the battery cell assembly is connected to the battery mounting assembly in a second posture, the second positive electrode conductive portion and the second negative electrode conductive portion are electrically connected to the positive electrode conductive portion and the negative electrode conductive portion of the battery cell of the battery cell assembly respectively. Therefore, regardless of whether the battery cell assembly is connected to the battery mounting assembly in the first posture or the second posture, the positive electrode conductive portion and the negative electrode conductive portion of the battery cell assembly can be aligned and electrically connected to a positive electrode conductive portion and a negative electrode conductive portion of the battery mounting assembly. When installing, there is no need to distinguish the installation direction of the battery cell assembly, which avoids damage to the instrument caused by incorrect installation of the battery cell assembly and also saves the time and effort of the operator to distinguish the installation direction of the battery cell assembly.

[0056] The structure of the battery mounting assembly of the specific embodiment of the present application will be described in detail below with reference to the drawings. It can be understood that the drawings and the following description of the specific embodiments do not limit the protection scope of the present application. The same reference numerals in the drawings represent the same or similar structures, and thus their repeated description will be omitted. In this embodiment, it is set that Figure 1 、 2 the S1 direction in 4, 5, 9 is the first direction, Figure 1 、 2 the S2 direction in 4, 5, 9 is the second direction, Figure 1 and Figure 9 the S3 direction in and is the third direction. The first direction, the second direction, and the third direction are directions set for the structure of the battery mounting assembly. The first direction, the second direction, and the third direction can be selected to be perpendicular to each other, but the present application is not limited thereto. An acute angle or an obtuse angle can also be formed between two of the first direction, the second direction, and the third direction according to needs.

[0057] Figures 1 - 9 shows the structure of the battery cell assembly 1 and the battery mounting assembly 20 in an embodiment of the present application. Figure 10The circuit schematic diagram of the connection between the battery cell assembly and the battery mounting assembly of this embodiment is shown. Among them, Figure 1 The schematic diagram of the battery cell assembly 1 of this embodiment cooperating with the battery mounting assembly 20 in the first posture is shown, Figure 2 The bottom view of the battery cell assembly 1 of this embodiment is shown. The battery cell assembly 1 includes a second mounting portion 13, and the second mounting portion 13 is a mounting hole provided on the end face of the battery cell assembly 1. A battery cell positive electrode conductive portion 11 and a battery cell negative electrode conductive portion 12 are provided in the second mounting portion 13. In this embodiment, the ends of the battery cell positive electrode conductive portion 11 and the battery cell negative electrode conductive portion 12 are respectively sheet-shaped 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 member 3 and a second conductive member 4. The first conductive member 3 and the second conductive member 4 are mounted on the mounting base 2. The first conductive member 3 includes a first positive electrode conductive portion 31, a first connecting portion 33 and a second positive electrode conductive portion 32 connected in sequence. The second conductive member 4 includes a first negative electrode conductive portion 41, a second connecting portion 43 and a second negative electrode conductive portion 42 connected in sequence. The mounting base 2 includes a bottom plate 21, a first mounting portion 22, a first support 23 and a second support 24. The bottom plate 21 includes a first surface and a second surface facing away from each other. The second surface 212 of the bottom plate 21 is the side surface facing the instrument body, and the first surface 211 of the bottom plate 21 is the side surface cooperating with the battery cell assembly 1. The first mounting portion 22, the first support 23 and the second support 24 are provided on the first surface 211 of the bottom plate 21. The first support 23 is used to fix the first positive electrode conductive portion 31 and the first negative electrode conductive portion 41. The second support 24 is used to fix the second positive electrode conductive portion 32 and the second negative electrode conductive portion 42. The first mounting portion 22 is a convex column protruding from the first surface 211 of the bottom plate 21, and the first mounting portion 22 can be inserted into the second mounting portion 13 of the battery cell assembly 1 to form an embedded connection. In this embodiment, the structures of the first mounting portion 22 and the second mounting portion 13 are only examples and do not limit the protection scope of this application. For example, in an alternative embodiment, the first mounting portion 22 can be a mounting hole provided on the bottom plate 21, and the second mounting portion 13 is a convex portion provided on the end face of the battery cell assembly 1. In another alternative embodiment, the first mounting portion 22 can be provided on the side of the bottom plate 21, and correspondingly the second mounting portion 13 is provided on the side of the battery cell assembly 1. In other alternative embodiments, the first mounting portion 22 and the second mounting portion 13 can also be connected by a snap connection.

[0059] When the battery cell assembly 1 is installed with the battery installation assembly 20, the battery cell assembly 1 can be plugged into the battery installation assembly 20 in a first posture or a second posture. Figure 1 The schematic diagram when the battery cell assembly 1 is plugged into the battery installation assembly 20 in the first posture is shown. Figure 9 The schematic diagram when the battery cell assembly 1 is plugged into the battery installation assembly 20 in the second posture is shown. As Figure 1 and Figure 2 shown, when the battery cell assembly 1 is connected to the battery installation assembly 20 in the first posture, the first support 23 is opposite to the battery cell positive electrode conductive part 11 and the battery cell negative electrode conductive part 12 of the battery cell assembly 1. After inserting the first installation part 22 into the second installation part 13, the first positive electrode conductive part 31 and the first negative electrode conductive part 41 are respectively electrically connected to the battery cell positive electrode conductive part 11 and the battery cell negative electrode conductive part 12 of the battery cell assembly 1. As Figure 2 and Figure 9 shown, when the battery cell assembly 1 is connected to the battery installation assembly 20 in the second posture, the second support 24 is opposite to the battery cell positive electrode conductive part 11 and the battery cell negative electrode conductive part 12 of the battery cell assembly 1. After inserting the first installation part 22 into the second installation part 13, the second positive electrode conductive part 32 and the second negative electrode conductive part 42 are respectively electrically connected to the battery cell positive electrode conductive part 11 and the battery cell negative electrode conductive part 12 of the battery cell assembly 1. The first posture and the second posture differ by 180°. When assembling the battery cell assembly 1 for the instrument body, the operator does not need to distinguish between the forward insertion and reverse insertion of the battery cell assembly 1. For example, taking the first posture as the forward insertion method and the second posture as the reverse insertion method, or taking the second posture as the forward 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 installation assembly 20 whether in the forward insertion method or the reverse insertion method.

[0060] Therefore, by adopting the battery installation assembly 20, whether the battery cell assembly 1 is connected to the battery installation assembly 20 in the first posture or the second posture, the battery cell positive electrode conductive part 11 and the battery cell negative electrode conductive part 12 of the battery cell assembly 1 can be aligned and electrically connected to a positive electrode conductive part and a negative electrode conductive part of the battery installation assembly 20. When installing, there is no need to distinguish the installation direction of the battery cell assembly 1, avoiding the damage of the instrument caused by the incorrect installation of the battery cell assembly 1, and also saving the time and energy of the operator to distinguish the installation direction of the battery cell assembly 1, making the operation of the surgical instrument more convenient.

[0061] As Figure 1 and Figure 2As shown, on one side of the second mounting portion 13 of the battery cell assembly 1 in the first direction, there is a first accommodating cavity 141, and on the other side, there is a second accommodating cavity 142. The first accommodating cavity 141, the second mounting portion 13, and the second accommodating cavity 142 are arranged in the first direction. The second mounting portion 13 extends in the third direction. On both inner walls of the second mounting portion 13, there are two second engaging portions 131 extending in the third direction. In the first accommodating cavity 141, there are a battery cell positive electrode conducting portion 11 and a battery cell negative electrode conducting portion 12, and the second accommodating cavity 142 is a cavity without a conducting portion provided. The battery cell positive electrode conducting portion 11 and the battery cell negative electrode conducting portion 12 are oppositely arranged in the second direction. The first mounting portion 22 of the mounting base 2 extends in the third direction, and on both sides of the first mounting portion 22, there are two first engaging portions 221 extending in the third direction. In this embodiment, the first engaging portion 221 is a protruding portion, and the second engaging portion 131 is a sliding groove. The first engaging portion 221 is embedded in the second engaging portion 131, which plays a guiding and limiting role when the battery cell assembly 1 is inserted into the battery mounting assembly 20, and limits that the battery cell assembly 1 can only be connected to the battery mounting assembly 20 in the first posture or the second posture. In other embodiments, the first engaging portion can also be a sliding groove, the second engaging portion can be a protruding portion, and the number and arrangement positions of the first engaging portion and the second engaging portion can also be adjusted according to needs, which also fall within the protection scope of this application. Here, the protruding portion can be a continuous convex rib or can include multiple spaced-apart protrusions.

[0062] As Figures 3 - 5 shown, the first support 23 and the second support 24 are respectively arranged on both sides of the first mounting portion 22 in 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 electrode conducting portion 31 and the first negative electrode conducting portion 41 are mounted on both sides of the first support 23 in the second direction, that is, the first positive electrode conducting portion 31 and the first negative electrode conducting portion 41 are aligned in the second direction. The second positive electrode conducting portion 32 and the second negative electrode conducting portion 42 are mounted on both sides of the second support 24 in the second direction, that is, the second positive electrode conducting portion 32 and the second negative electrode conducting portion 42 are aligned in the second direction. The first positive electrode conducting portion 31 and the second negative electrode conducting portion 42 are aligned in the first direction, and the second positive electrode conducting portion 32 and the first negative electrode conducting portion 41 are aligned in the first direction. Therefore, no matter whether the battery cell assembly is inserted into the battery mounting assembly 20 in the first posture or the second posture, it can ensure that a set of positive electrode conducting portion and negative electrode conducting portion are accurately inserted into the first accommodating cavity in alignment, and are electrically connected to the battery cell positive electrode conducting portion and the battery cell negative electrode conducting portion of the battery cell assembly.

[0063] As Figure 6 and Figure 8As shown, the first support 23 and the second support 24 extend along the third direction. The first positive electrode conductive part 31, the second positive electrode conductive part 32, the first negative electrode conductive part 41 and the second negative electrode conductive part 42 at least partially extend along the third direction. First sliding grooves 231 are respectively provided on both sides of the first support 23. The first positive electrode conductive part 31 includes a first bending part 311, and the first negative electrode conductive part 41 includes a second bending part 411. The ends of the first positive electrode conductive part 31 and the first negative electrode conductive part 41 are embedded in the first sliding grooves 231 and can slide in the first sliding grooves 231. Therefore, the first sliding grooves 231 leave a space for the elastic deformation of the first bending part 311 and the second bending part 411. Second sliding grooves 241 are respectively provided on both sides of the second support 24. The second positive electrode conductive part 32 includes a third bending part 321, and the second negative electrode conductive part 42 includes a fourth bending part 421. The ends of the second positive electrode conductive part 32 and the second negative electrode conductive part 42 are embedded in the second sliding grooves 241 and can slide in the second sliding grooves 241. Therefore, the second sliding grooves 241 leave a space for the elastic deformation of the third bending part 321 and the fourth bending part 421.

[0064] As Figure 1 , Figure 5 and Figure 6 shown, both of the two positive electrode conductive parts on the battery mounting assembly 20 are provided on the first conductive member 3, and both of the two negative electrode conductive parts are provided on the second conductive member 4. The first conductive member 3 and the second conductive member 4 respectively only need to be provided with one pin connected to the instrument body. Through the two conductive members, the battery cell assembly 1 can be connected to the instrument body to transmit electric energy to the instrument body, and the structure is simple, and the production, assembly and maintenance are more convenient. Specifically, the first conductive member 3 further includes a first pin 34, the second conductive member 4 further includes a second pin 44, and the second pin 44 passes through the through hole 215 (shown in Figure 8 ) of the bottom plate 21, and the first pin 34 and the second pin 44 extend in a direction away from the first surface 211 of the bottom plate 21 relative to the bottom plate 21. The first pin 34 is used to connect the positive power supply input end of the instrument body, and the second pin 44 is used to connect the negative power supply input end of the instrument body.

[0065] As Figures 4 - 8As shown, the first conductive member 3 is an integrally formed conductive sheet, and the second conductive member 4 is an integrally formed conductive sheet. However, the present application is not limited thereto. In other alternative embodiments of the present application, the first conductive member 3 may also include multiple conductive segments fixedly connected, and / or the second conductive member 4 may also include multiple conductive segments fixedly connected. The first connecting portion 33 and the second connecting portion 43 extend along the surface of the bottom plate 21. A plurality of conductive member fixing members 25 are provided on the bottom plate 21. Mounting holes are respectively provided on the first connecting portion 33 and the second connecting portion 43. The conductive member fixing members 25 are passed through the mounting holes to fix the first connecting portion 33 and the second connecting portion 43 on the surface of the bottom plate 21. The first connecting portion 33 and the second connecting portion 43 cannot be conductively connected in a crossed manner, so that the first connecting portion 33 and the second connecting portion 43 are insulated from each other, realizing insulation isolation between the positive conductive sheet and the negative conductive sheet. In order to achieve displacement isolation between the first connecting portion 33 and the second connecting portion 43, at least a part of the first connecting portion 33 is provided on one side of the first surface 211 of the bottom plate 21, at least a part of the second connecting portion 43 is provided on one side of the first surface 211 of the bottom plate 21, and a part of one of the first connecting portion 33 and the second connecting portion 43 is provided on the second surface 212 side of the bottom plate 21 to avoid the other connecting portion. For example, the second connecting portion 43 is integrally provided on one side of the first surface 211 of the bottom plate 21. A part of the first connecting portion 33 is provided on one side of the first surface 211 of the bottom plate 21 to be connected to the first positive conductive portion 31 and the second positive conductive portion 32. Another part of the first connecting portion 33 is provided on the second surface 212 side of the bottom plate 21 to avoid the second connecting portion 43. Or, the first connecting portion 33 is integrally provided on one side of the first surface 211 of the bottom plate 21. A part of the second connecting portion 43 is provided on one side of the first surface 211 of the bottom plate 21 to be connected to the first negative conductive portion 41 and the second negative conductive portion 42. Another part of the second connecting portion 43 is provided on the second surface 212 side of the bottom plate 21 to avoid the first connecting portion 33.

[0066] In this embodiment, an example is given in which a part of the first connecting portion 33 is provided on the second surface 212 side of the bottom plate 21 for illustration. As Figures 4 - 8As shown, the bottom plate 21 is provided with a first opening 213 and a second opening 214. The first connecting portion 33 includes a first extension section 331, a first stepped section 332, a second extension section 333, a second stepped section 334, and a third extension section 335 that are connected in sequence. The first extension section 331 and the third extension section 335 are located on one side of the first surface 211 of the bottom plate 21. The first extension section 331 is connected to the first positive conductive portion 31, and the third extension section 335 is connected to the second positive conductive portion 32. The first stepped section 332 and the second stepped section 334 are respectively passed through the first opening 213 and the second opening 214, and the second extension section 333 is connected between the first stepped section 332 and the second stepped section 334 and is located on one side of the second surface 212 of the bottom plate 21 to avoid the second connecting portion 43. Moreover, the second extension section 333 has a first corner 3331 to avoid the second connecting portion 43. The second connecting portion 43 is integrally located on one side of the first surface 211 of the bottom plate 21 and includes a fourth extension section 431, a fifth extension section 432, and a sixth extension section 433 that are connected in sequence. The fourth extension section 431 is connected to the first negative conductive portion 41, and the sixth extension section 433 is connected to the second negative conductive portion 42. The fifth extension section 432 is provided with a second corner 4321 to avoid the first connecting portion 33.

[0067] As Figures 4 - 8 shown, the first corner 3331 of the second extension section 333 is located at a position where the second extension section 333 and the fifth extension section 432 are spatially staggered. By providing the first corner 3331, part of the second extension section 333 and the first extension section 331 are located inside the fourth extension section 431 (the side closer to each conductive portion). The second corner 4321 of the fifth extension section 432 is located at a position where the fifth extension section 432 and the second stepped section 334 are spatially staggered. By providing the second corner 4321, part of the fifth extension section 432 and the sixth extension section 433 are located inside the third extension section 335 (the side closer to each conductive portion). In another alternative embodiment, the second corner 4321 can also be provided at a position where the fifth extension section 432 and the first stepped section 332 are spatially staggered. As Figures 3 - 6 shown, through the structural design of the battery mounting assembly 20 of this embodiment, the first connecting portion 33 and the second connecting portion 43 can occupy a relatively small distribution area without interfering with each other, and better insulation isolation between the first conductive member 3 and the second conductive member 4 can be achieved through the barrier of the bottom plate 21 at the spatially staggered 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 section, the first stepped stage, a second extension section, the second stepped stage, and a third extension section that are connected in sequence. The first extension section and the third extension section are disposed on one side of the first surface of the bottom plate. The first extension section is connected to the first negative electrode conductive portion, and the third extension section is connected to the second negative electrode conductive portion. The second extension section is disposed on one side of the second surface of the bottom plate. The first stepped portion and the second stepped portion respectively pass through the first opening and the second opening. The second extension section is provided with the first corner. The first connecting portion is wholly disposed on one side of the first surface of the bottom plate and includes a fourth extension section, a fifth extension section, and a sixth extension section that are connected in sequence. The fourth extension section is connected to the first positive electrode conductive portion, the fifth extension section is connected to the second positive electrode conductive portion, and the fifth extension section is provided with the second corner.

[0069] Figure 10 FIG. is a circuit schematic diagram of the cooperation between the battery cell assembly and the battery mounting assembly for this embodiment. Here, it is exemplified that there are four battery cells B1 to B4 in the battery cell assembly. In other alternative embodiments of the present application, the number of battery cells can be selected and adjusted according to needs. The battery cell assembly has a unified battery cell positive electrode conductive portion 11 and a battery cell negative electrode conductive portion 12 for outputting the electric energy in the battery cell assembly to the outside. In this embodiment, multiple battery cells in the battery cell assembly are all connected in series in sequence. The positive electrode of the first battery cell leads out the battery cell positive electrode conductive portion 11, and the negative electrode of the last battery cell leads out the battery cell negative electrode conductive portion 12. The working principle of the battery mounting assembly will be specifically described below in conjunction with Figure 10 to specifically illustrate the working principle of this battery mounting assembly.

[0070] Combined with Figure 1 , Figure 3 , Figure 4 and Figure 10As shown, when the battery cell assembly 1 is connected to the battery mounting assembly 20 in the first posture, the first mounting portion 22 enters the second mounting portion 13, the first support 23, the first positive electrode conductive portion 31, and the first negative electrode conductive portion 41 enter the first accommodating cavity 141. The first bending portion 311 of the first positive electrode conductive portion 31 and the second bending portion 411 of the first negative electrode conductive portion 41 are respectively subjected to the acting forces of the battery cell positive electrode conductive portion 11 and the battery cell negative electrode conductive portion 12 and elastically deformed. The stability of the first support 23 mounted in the first accommodating cavity 141 is maintained by the elastic acting forces of the first bending portion 311 and the second bending portion 411. The first positive electrode conductive portion 31 is electrically connected to the battery cell positive electrode conductive portion 11, and the first negative electrode conductive portion 41 is electrically connected to the battery cell negative electrode conductive portion 12. At this time, the electric energy of the battery cell assembly can be transmitted to the positive power supply input end and the negative power supply input end of the instrument body through the first pin 34 and the second pin 44. The second support 24, the second positive electrode conductive portion 32, and the second negative electrode conductive portion 42 enter the second accommodating cavity 142. The third bending portion 321 and the fourth bending portion 421 of the second positive electrode conductive portion 32 and the second negative electrode conductive portion 42 are elastically deformed by the acting forces of the inner wall of the second accommodating cavity 142, and the stability of the second support 24 mounted in the second accommodating cavity 142 is maintained by the elastic acting forces of the third bending portion 321 and the fourth bending portion 421.

[0071] Combined Figure 9 、 Figure 3 、 Figure 4 and Figure 10 As shown, when the battery cell assembly 1 is connected to the battery mounting assembly 20 in the second posture, the first mounting portion 22 enters the second mounting portion 13, the first support 23, the first positive electrode conductive portion 31, and the first negative electrode conductive portion 41 enter the second accommodating cavity 142. The first bending portion 311 and the second bending portion 411 are elastically deformed by the acting forces of the inner wall of the second accommodating cavity 142, and the stability of the first support 23 mounted in the second accommodating cavity 142 is maintained by the elastic acting forces of the first bending portion 311 and the second bending portion 411. The second support 24, the second positive electrode conductive portion 32, and the second negative electrode conductive portion 42 enter the first accommodating cavity 141. The third bending portion 321 and the fourth bending portion 421 are elastically deformed by the acting forces of the battery cell positive electrode conductive portion 11 and the battery cell negative electrode conductive portion 12, and the stability of the second support 24 mounted in the first accommodating cavity 141 is maintained by the elastic acting forces of the third bending portion 321 and the fourth bending portion 421. The second positive electrode conductive portion 32 is electrically connected to the battery cell positive electrode conductive portion 11, and the second negative electrode conductive portion 42 is electrically connected to the battery cell negative electrode conductive portion 12. At this time, the electric energy of the battery cell assembly can be transmitted to the positive power supply input end and the negative power supply input end of the instrument body through the first pin 34 and the second pin 44.
