It should be understood that the accompanying drawings and the following description of the embodiment are not intended to limit the protection scope of the present application. The same reference numerals in the drawings represent the same or similar structures, and thus repeated description thereof will be omitted. In this embodiment, the S1 direction in FIGS. 1, 2, 4, 5 and 9 is set as the first direction, the S2 direction in FIGS. 1, 2, 4, 5 and 9 is set as the second direction, the S3 direction in FIGS. 1 and 9 is set as the third direction, and the first direction, the second direction and the third direction are set as directions with respect to the structure of the battery mounting assembly. The first direction, the second direction and the third direction can be perpendicular to each other, but the present application is not limited thereto, and two of the first direction, the second direction and the third direction can also be set as an acute angle or an obtuse angle according to requirements.

[0034] FIGS. 1 to 9 show the structure of the battery cell assembly 1 and the battery mounting assembly 20 according to an embodiment of the present application, and FIG. 10 shows a circuit principle diagram of the connection between the battery cell assembly and the battery mounting assembly according to the embodiment. FIG. 1 shows a schematic view of the cooperation between the battery cell assembly 1 and the battery mounting assembly 20 according to the embodiment in a first posture, and FIG. 2 shows a bottom view of the battery cell assembly 1 according to the embodiment. The battery cell assembly 1 comprises a second mounting part 13, which is a mounting hole arranged on the end surface of the battery cell assembly 1, and the second mounting part 13 is provided with a battery cell positive electrode conductive part 11 and a battery cell negative electrode conductive part 12. In this embodiment, the ends of the battery cell positive electrode conductive part 11 and the battery cell negative electrode conductive part 12 are respectively in the form of a sheet-shaped conductive structure.

[0035] Figures 3-5 show the structure of the battery mounting assembly 20. The battery mounting assembly 20 includes a mounting base 2, a first conductive member 3 and a second conductive member 4, which are mounted to the mounting base 2. The first conductive member 3 includes a first positive conductive portion 31, a first connecting portion 33 and a second positive conductive portion 32 connected in sequence, and the second conductive member 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 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 opposite to each other. The second surface 212 of the bottom plate 21 is a side surface facing the body of the instrument, and the first surface 211 of the bottom plate 21 is a side surface cooperating with the battery cell assembly 1. The first mounting portion 22, the first support 23 and the second support 24 are arranged on the first surface 211 of the bottom plate 21, the first support 23 is used to fix the first positive conductive portion 31 and the first negative conductive portion 41, and the second support 24 is used to fix the second positive conductive portion 32 and the second negative conductive portion 42. The first mounting portion 22 is a protrusion arranged on 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 structure of the first mounting portion 22 and the second mounting portion 13 is only an example, and is not intended to limit the scope of protection of the present application. For example, in an alternative embodiment, the first mounting portion 22 can be a mounting hole arranged on the bottom plate 21, and the second mounting portion 13 is a protrusion arranged on the end surface of the battery cell assembly 1. In another alternative embodiment, the first mounting portion 22 can be arranged on the side edge of the bottom plate 21, and correspondingly the second mounting portion 13 is arranged on the side edge 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 buckle.

[0036] When the battery mounting assembly 20 is mounted with the battery cell assembly 1, the battery cell assembly 1 can be inserted into the battery mounting assembly 20 in a first orientation or a second orientation. FIG. 1 shows a schematic view of the battery cell assembly 1 inserted into the battery mounting assembly 20 in the first orientation, and FIG. 9 shows a schematic view of the battery cell assembly 1 inserted into the battery mounting assembly 20 in the second orientation. As shown in FIGS. 1 and 2, when the battery cell assembly 1 is connected to the battery mounting assembly 20 in the first orientation, the first support 23 is opposite the positive electrode conductive part 11 and the negative electrode conductive part 12 of the battery cell assembly 1. After the first mounting part 22 is inserted into the second mounting part 13, the first positive electrode conductive part 31 and the first negative electrode conductive part 41 are electrically connected to the positive electrode conductive part 11 and the negative electrode conductive part 12 of the battery cell assembly 1, respectively. As shown in FIGS. 2 and 9, when the battery cell assembly 1 is connected to the battery mounting assembly 20 in the second orientation, the second support 24 is opposite the positive electrode conductive part 11 and the negative electrode conductive part 12 of the battery cell assembly 1. After the first mounting part 22 is inserted into the second mounting part 13, the second positive electrode conductive part 32 and the second negative electrode conductive part 42 are electrically connected to the positive electrode conductive part 11 and the negative electrode conductive part 12 of the battery cell assembly 1, respectively. The first orientation and the second orientation are 180° apart. When the battery cell assembly 1 is mounted on the instrument body, the operator does not need to distinguish between the forward insertion and the reverse insertion of the battery cell assembly 1. For example, the first orientation is taken as the forward insertion, and the second orientation is taken as the reverse insertion, or the second orientation is taken as the forward insertion, and the first orientation is taken as the reverse insertion. The operator can achieve correct electrical connection between the battery cell assembly 1 and the battery mounting assembly 20 regardless of the forward insertion or the reverse insertion.

[0037] Therefore, by using the battery mounting assembly 20, the positive electrode conductive part 11 and the negative electrode conductive part 12 of the battery cell assembly 1 can be aligned and electrically connected to one positive electrode conductive part and one negative electrode conductive part of the battery mounting assembly 20 regardless of whether the battery cell assembly 1 is connected to the battery mounting assembly 20 in the first orientation or the second orientation. The operator does not need to distinguish between the installation direction of the battery cell assembly 1, which avoids damage to the instrument caused by incorrect installation of the battery cell assembly 1 and saves the time and effort of the operator in distinguishing between the installation direction of the battery cell assembly 1, making the operation of the surgical instrument more convenient.

[0038] As shown in FIG. 1 and FIG. 2, the battery cell assembly 1 is provided with a first accommodating cavity 141 on one side of the second mounting portion 13 along the first direction, and a second accommodating cavity 142 on the other side.

The second mounting portion 13 extends along the third direction. The two side walls of the second mounting portion 13 are provided with two second matching portions 131 extending along the third direction. The first accommodating cavity 141 is provided with a battery cell positive electrode conductive portion 11 and a battery cell negative electrode conductive portion 12, and the second accommodating cavity 142 is a cavity without a conductive portion. The battery cell positive electrode conductive portion 11 and the battery cell negative electrode conductive portion 12 are oppositely arranged along the second direction. The first mounting portion 22 of the mounting seat 2 extends along the third direction, and the two sides of the first mounting portion 22 are provided with two first matching portions 221 extending along the third direction. In this embodiment, the first matching portion 221 is a protruding portion, and the second matching portion 131 is a sliding groove. The first matching portion 221 is embedded in the second matching 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 the battery cell assembly 1 to be connected to the battery mounting assembly 20 in the first posture or the second posture. In other embodiments, the first matching portion can also be a sliding groove, and the second matching portion can be a protruding portion. The number and arrangement position of the first matching portion and the second matching portion can also be adjusted as needed, which also belongs to the protection scope of the present application. Here, the protruding portion can be a continuous protruding rib, or can include a plurality of protrusions arranged at intervals.

[0039] As shown in FIG. 3-5, the first support 23 and the second support 24 are arranged on the two sides of the first mounting portion 22 along the first direction, i.e., the first support 23, the first mounting portion 22 and the second support 24 are arranged along the first direction. The first positive electrode conductive portion 31 and the first negative electrode conductive portion 41 are arranged on the two sides of the first support 23 along the second direction, i.e., the first positive electrode conductive portion 31 and the first negative electrode conductive portion 41 are aligned along the second direction.

The first positive electrode conductive portion 31 and the second negative electrode conductive portion 42 are aligned along the first direction, and the second positive electrode conductive portion 32 and the first negative electrode conductive portion 41 are aligned along the first direction. Therefore, whether the battery cell assembly is inserted into the battery mounting assembly 20 in the first posture or the second posture, a group of positive electrode conductive portions and negative electrode conductive portions can be accurately aligned and inserted into the first accommodating cavity to be electrically connected with the battery cell positive electrode conductive portion and the battery cell negative electrode conductive portion of the battery cell assembly.

[0040] As shown in FIG. 6 and FIG. 8, 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 at least partially extend along the third direction.

[0041] As shown in FIG. 1, FIG. 5 and FIG. 6, the two positive conductive parts on the battery mounting assembly 20 are provided on the first conductive part 3, and the two negative conductive parts are provided on the second conductive part 4, thus only one pin connected to the body of the instrument needs to be provided on the first conductive part 3 and the second conductive part 4, and the battery cell assembly 1 can be connected to the body of the instrument through the two conductive parts to transmit electric energy to the body of the instrument, thus the structure is simple and the production, assembly and maintenance are more convenient. Specifically, the first conductive part 3 further comprises a first pin 34, the second conductive part 4 further comprises a second pin 44, the second pin 44 is provided in a through hole 215 (shown in FIG. 8) of the bottom plate 21, and the first pin 34 and the second pin 44 extend away from a first surface 211 of the bottom plate 21.

The first connecting portion 33 and the second connecting portion 43 cannot cross over to conduct, so as to insulate the first connecting portion 33 and the second connecting portion 43 from each other, and achieve insulation and isolation between the positive conductive sheet and the negative conductive sheet. In order to achieve clearance isolation between the first connecting portion 33 and the second connecting portion 43, the first connecting portion 33 is at least partially provided on one side of the first surface 211 of the bottom plate 21, the second connecting portion 43 is at least partially provided on one side of the first surface 211 of the bottom plate 21, and a portion of one of the first connecting portion 33 and the second connecting portion 43 is provided on one side of the second surface 212 of the bottom plate 21 to avoid the other connecting portion.
