[0040] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] It should be understood that the terms "proximal" and "distal" as used herein are relative to the clinician manipulating the surgical instrument. The term "proximal" refers to the portion close to the clinician, and the term "distal" refers to the portion away from the clinician. However, surgical instruments can be used in many directions and positions, so these terms expressing relative positional relationships are not limited and absolute.

[0042] In the present invention, unless otherwise clearly specified and limited, the terms such as "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a movably connection, or an integral body; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements such as abutment. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. It should be noted that when there are qualifiers before "connected" and "connection", they have the meaning defined by the corresponding qualifiers, and only exclude situations that obviously need to be excluded, and do not exclude other possible situations. For example, "detachably connected" refers to a detachable connection, and does not include integration, but movable connection, etc. are not excluded.

[0043] See also Figures 1 to 3 The present invention provides a battery device, including a battery assembly 10, an insulating member 20 and a box body 80. The insulating member 20 is disposed in the box body 80, and the insulating member 20 is pluggably connected to the battery assembly 10. The battery assembly 10 includes a battery pack 30, a reed assembly 40 and a discharge circuit, wherein the reed assembly 40 includes a first reed 41 and a second reed 42, and the battery pack 30, the first reed 41, the second reed 42 and the discharge circuit form a series circuit.

[0044] The battery assembly 10 has a storage state and a use state.

[0045] In the storage state, the battery assembly 10 is accommodated in the box body 80, and the insulating member 20 is inserted between the first reed 41 and the second reed 42 to isolate the first reed 41 and the second reed 42, and the series circuit does not form a closed loop.

[0046] In response to the battery assembly switching from the storage state to the use state, the battery assembly 10 separates from the insulating member 20 to detach from the box body 80, the first reed 41 and the second reed 42 contact each other, and the series circuit forms a closed loop, so that the battery pack 30 discharges through the discharge circuit.

[0047] By setting the insulating member 20 in the box body 80 and pluggably connecting it to the battery assembly 10, the battery assembly 10 can be accommodated in the box body 80 in the storage state, and while being protected by the box body 80, the insulating member 20 is inserted between the first reed 41 and the second reed 42 to isolate the first reed 41 and the second reed 42, preventing the series circuit from forming a closed loop, so that the battery assembly 10 will not self-discharge before being taken out of the box body 80, avoiding the battery assembly 10 from running out of power when used by the doctor, and being unable to perform surgery. When surgery is required, the doctor takes the battery assembly 10 out of the box body 80 and installs it on the surgical instrument, and at the same time the insulating member 20 is separated from the battery assembly 10, the first reed 41 and the second reed 42 are in contact, so that the series circuit forms a closed loop, and the battery assembly 10 begins to self-discharge through the discharge circuit, thereby ensuring that the battery assembly 10 is used normally and self-discharges at the same time, ensuring that the surgery can be performed normally and meeting environmental protection requirements.

[0048] It is understandable that before use, the battery assembly 10 is installed in the box body 80, thereby preventing the battery assembly 10 from self-discharging and facilitating storage and fixing. Only when the doctor is about to perform surgery and use surgical instruments, will the battery assembly 10 be taken out of the box body 80 and installed in the surgical instruments. When taking it out, the discharge circuit will be connected and self-discharging will begin. In this way, the doctor does not need to perform other additional operations to enable the battery assembly 10 to self-discharge, without relying on personal usage habits, to avoid the doctor not knowing or forgetting the self-discharging operation, resulting in the battery assembly 10 not being able to self-discharge normally. The above-mentioned method of self-discharging only when the battery assembly 10 is completely pulled out of the box body 80 effectively prevents the battery assembly 10 from being discharged prematurely due to vibrations during transportation, resulting in the battery being exhausted during use.

[0049] See also Figures 1 to 5 ,as well as Fig. 9 The insulating member 20 includes a base 21 and an insulating plug 23. The base 21 is connected to the box body 80. The insulating plug 23 is arranged on the base 21. In the storage state, the insulating plug 23 is inserted between the first spring 41 and the second spring 42 to isolate the first spring 41 and the second spring 42.

[0050] For further information, please refer to Figure 1 , Figure 3 and Fig. 9 The insulating member 20 further includes a connecting column 22. The connecting column 22 is disposed on the base 21, and the connecting column 22 extends into the battery assembly 10 and is engaged with the battery assembly 10, that is, the insulating member 20 is connected to the battery assembly 10 through the connecting column 22. In this embodiment, the connecting column 22 and the insulating plug 23 are an integrated structure, so as to facilitate the molding of the insulating member 20. Of course, the connecting column 22 can also be spaced apart from the insulating plug 23, which can be selected according to actual needs.

[0051] See also Fig. 9 The connecting column 22 has a hollow cavity, that is, the connecting column 22 is a hollow structure similar to a sleeve. Specifically, the cross section of the connecting column 22 is a quadrilateral. The two side walls of the connecting column 22 respectively have a connecting section 221 extending axially from bottom to top. The two sides of the connecting section 221 are spaced apart from the side walls of the connecting column 22 to form a separate section. That is, only the lower end of the connecting section 221 is connected to the connecting column 22 as a connecting end, so it has a certain elasticity. The free end of the connecting section 221 has a connecting structure, and the battery assembly 10 has a matching structure 121. The connecting structure is matched and connected with the matching structure 121 to achieve the connection between the insulating member 20 and the battery assembly 10.

[0052] See also Fig. 9 In this embodiment, the connection structure is a buckle 222, and the buckle 222 is engaged with the matching structure 121. Figure 2 The matching structure 121 is a matching column with a hollow channel. The cross-sectional shape of the hollow channel is adapted to the cross-sectional shape of the connecting column 22, so that the connecting column 22 can just extend into the hollow channel of the matching structure 121. The connecting structure is matched and connected with the top of the matching column, that is, the buckle 222 is engaged and limited with the top of the matching column. Specifically, the buckle 222 protrudes radially from the side wall of the connecting column 22 in the initial state, and shrinks inwardly under compression in the hollow channel. After the buckle 222 extends out of the hollow channel, it returns to a natural state, thereby engaging and limiting with the top of the matching column, thereby achieving the engagement of the insulating member 20 with the battery assembly 10. Through the above-mentioned arrangement, the matching structure 121 realizes the connection between the insulating part 20 and the battery assembly 10 by snapping with the buckle 222. At the same time, the matching structure 121 provides a guiding channel for the connecting column 22, thereby ensuring that the connecting column 22 can smoothly and accurately enter the battery assembly 10, and further ensuring that the insulating plug 23 can be accurately inserted between the first spring leaf 41 and the second spring leaf 42 to isolate the first spring leaf 41 and the second spring leaf 42, thereby realizing the insulating function of the insulating plug 23.

[0053] Specifically, the radial width of the buckle 222 gradually increases from bottom to top, so that it gradually protrudes from the side wall of the connecting column 22, so that the outer side surface of the buckle 222 is an arc surface. In this way, the arc surface serves as a guide surface. When the doctor needs to use surgical instruments to pull out the battery assembly 10, the two buckles 222 can be retracted inward along the guide surface without too much effort to release the clamping connection with the top of the matching column, so that the battery assembly 10 can be easily taken out of the box body 80 for convenient use.

[0054] In this embodiment, the insulating member 20 also has a limiting structure, and the limiting structure has an initial state and an avoidance state. In the initial state, the limiting structure and the battery assembly 10 are limited and stopped. In the avoidance state, the insulating member 20 can be inserted into the battery assembly 10. When the battery assembly 10 is separated from the insulating member 20, the limiting structure can be limited and stopped with the battery assembly 10 to prevent the insulating member 20 from being inserted into the battery assembly 10 again, thereby preventing the doctor from reinstalling the used battery assembly 10 back into the box body 80, avoiding the battery assembly 10 from being in a charged state when discarded, and meeting the requirements of environmental protection.

[0055] For further information, see Figure 6 to Figure 7 , the bottom of the battery assembly 10 has an avoidance groove 131 for avoiding the insulating member 20, and the shape of the avoidance groove 131 is adapted to the cross-sectional shape of the connecting column 22 and the insulating plug 23, so as to facilitate the insertion of the insulating member 20 from the avoidance groove 131 into the battery assembly 10. It can be understood that the matching structure 121 is arranged correspondingly and connected to the avoidance groove 131 above and below. In this embodiment, the limiting structure and the connecting structure are the same structure, that is, the limiting structure is a buckle 222. In the initial state, the buckle 222 protrudes radially from the side wall of the connecting column 22, that is, the width at the top of the connecting column 22 is greater than the width of the avoidance groove 131, thereby preventing the insulating member 20 from being inserted into the battery assembly 10 again after being separated from the battery assembly 10. In the avoidance state, the buckle 222 is squeezed and retracted inward, so that it is accommodated in the connecting column 22 to avoid the battery assembly 10, so that the insulating member 20 can be inserted into the battery assembly 10.

[0056] In this embodiment, since the area of ​​the box body 80 where the battery assembly 10 is installed is small, if the doctor presses the buckle 222 by hand, the finger will occupy a larger part of the installation space, thereby blocking the connection between the battery assembly 10 and the insulating member 20. It is necessary to use a special tool with a smaller head and a curved feature to clamp the buckle 22 to deform it so that the insulating member 20 can be reinserted into the battery assembly 10 without affecting the connection between the battery assembly 10 and the insulating member 20, thereby avoiding the reuse of the battery assembly 10.

[0057] In an optional embodiment, the limiting structure includes a limiting member and an elastic member. The side wall of the connecting column 22 has a receiving groove, at least a portion of the limiting member and the elastic member are received in the receiving groove, and the elastic member is connected to the limiting member. Specifically, one end of the elastic member is connected to the bottom of the receiving groove, and the other end is connected to the limiting member. In the initial state, in response to the elastic force of the elastic member, the other part of the limiting member protrudes from the receiving groove, that is, protrudes from the side wall of the connecting column 22, thereby blocking the insertion of the battery assembly 10 and the insulating member 20. In the avoidance state, the limiting member is squeezed and accommodated in the receiving groove to avoid the battery assembly 10, so that the insulating member 20 can be inserted into the battery assembly 10. Further, the limiting structure can be one or more, and when there are multiple limiting structures, multiple limiting structures are arranged at intervals along the circumference and / or axial direction of the connecting column 22. Specifically, the limiting member can be a ball, a limiting pin, etc., and the elastic member can be a spring, etc., which can be selected according to actual needs.

[0058] See also Fig. 9 , the connecting column 22 also has a guide rib 223 extending in the axial direction, and the guide rib 223 protrudes from the outer surface of the connecting column 22. Specifically, in this embodiment, the two connecting sections 221 are located on the two opposite side walls of the four side walls of the connecting column 22, and the guide rib 223 is located on one of the other two side walls, so that the cross section of the connecting column 22 is convex-shaped, and accordingly, the part of the avoidance groove 131 corresponding to the connecting column 22 is convex-shaped, and further, the hollow channel of the matching structure 121 is also convex-shaped, so as to facilitate guiding the connecting column 22 to extend into the hollow channel of the matching structure 121. In other words, the shape of the avoidance groove 131 and the cross-sectional shape of the hollow channel are compatible with the overall cross-sectional shape of the connecting column 22. Of course, there can be multiple guide ribs 223, and other guide ribs 223 can be set on another of the other two side walls, or a side wall is provided with multiple guide ribs 223 at intervals, which can be selected according to actual needs. Through the above-mentioned arrangement, the guide rib 223 can cooperate with the matching structure 121 to provide guidance for the connecting column 22 to enter the hollow channel while preventing the connecting column 22 from circumferentially deflecting during the process of entering the hollow channel, so that the insulating plug 23 will not deflect circumferentially during the process of entering the hollow channel, ensuring that the insulating plug 23 can be accurately inserted between the first reed 41 and the second reed 42 at a preset angle to isolate the first reed 41 and the second reed 42, thereby realizing the insulation function of the insulating plug 23.

[0059] See also Figure 6, the battery assembly 10 further includes an upper cover 11, a middle cover 12 and a lower cover 13 connected in sequence. The middle cover 12 is the main structure of the battery assembly 10, and is used to accommodate and install components such as the battery pack 30. The matching structure 121 is also located in the middle cover 12. The lower cover 13 is provided with the above-mentioned avoidance groove 131, so that the insulating member 20 can be inserted into the battery assembly 10 from below. In this embodiment, the battery pack 30 includes four batteries 31 connected in series, namely, batteries No. 1, No. 2, No. 3 and No. 4, the reed assembly 40 further includes a third reed 43, a fourth reed 44, a fifth reed 45 and a sixth reed 46, and the battery assembly 10 further includes an overcurrent protection sheet 50. Specifically, the positive electrode of battery No. 1 and the negative electrode of battery No. 2 are connected through the third reed 43, the positive electrode of battery No. 3 and the negative electrode of battery No. 4 are connected through the fourth reed 44, and the negative electrode of battery No. 1 and the positive electrode of battery No. 4 are connected through the overcurrent protection sheet 50. Furthermore, the battery assembly 10 also includes a discharge plate 60, and the first reed 41, the second reed 42, the fifth reed 45 and the sixth reed 46 are all arranged on the discharge plate 60, and the negative electrode of battery No. 3 and the positive electrode of battery No. 2 are respectively connected to the fifth reed 45 and the sixth reed 46, thereby forming a series circuit.

[0060] In this embodiment, the first spring piece 41 and the second spring piece 42 are both arc-shaped and have a certain elasticity. The arc openings of the two spring pieces are opposite, so that when there is no insulating insert 23 separating them, they are always in abutment due to their own elasticity. Figure 8 The discharge plate 60 has an avoidance notch 61 at the corresponding positions between the first spring piece 41 and the second spring piece 42 , so that the insulating plug 23 can be inserted between the first spring piece 41 and the second spring piece 42 .

[0061] See also Figure 6 The discharge circuit includes a resistor 70, which is arranged on the discharge plate 60. There is at least one resistor 70. The resistor 70 is connected in series with the battery pack 30, the first reed 41 and the second reed 42. When the series circuit forms a closed loop, the battery pack 30 discharges through the resistor 70.

[0062] Fig.10The circuit diagram of the battery assembly 10 in this embodiment is shown. In this embodiment, one battery 31 provides a voltage of 3V, and four batteries 31 connected in series can provide a voltage of 12V. The positive and negative poles of the battery pack 30 are connected to the discharge circuit through the fifth reed 45 and the sixth reed 46, respectively. Specifically, the discharge circuit has two resistors 70 connected in series, namely resistors R1 and R2, for example, both are 100Ω. When the insulating plug 23 is not pulled out from the first reed 41 and the second reed 42, the resistors R1 and R2 are not connected to the circuit and will not discharge; when the insulating plug 23 is pulled out from the first reed 41 and the second reed 42, the current flows out from the positive pole of the battery pack 30, passes through the resistors R1 and R2, and returns to the negative pole of the battery pack 30, and self-discharges by generating heat through the two resistors 70.

[0063] In this embodiment, the insulating member 20 is detachably connected to the box body 80. Figures 1 to 3 The two side walls of the box body 80 have a stopper section 81 that is recessed inwards. The stopper section 81 is located at the lower end of the box body 80. An area for accommodating the base 21 is formed between the stopper section 81 and the bottom wall of the box body 80, and the stopper section 81 and the base 21 of the insulating member 20 are stopped and limited. It can be understood that the limiting area of ​​the box body 80 is adapted to the base 21. Specifically, the bottom surface of the stopper section 81 is a horizontal stopper surface, which cooperates with the top surface of the base 21 to stop. The width between the two stopper sections 81 is smaller than the length of the base 21, so that the base 21 is limited at the bottom of the box body 80 in the up and down direction. In this way, when the doctor takes out the battery assembly 10 from the box body 80, the insulating member 20 will not be separated from the box body 80.

[0064] Before the battery device leaves the factory, the insulating member 20 can be inserted into the battery assembly 10 first, and then the insulating member 20 and the battery assembly 10 are installed in the box body 80 together, and the installation with the box body 80 is achieved by cooperating with the stopper of the box body 80. Specifically, a special tool with a small head and a curved feature is used to squeeze and shrink the buckle 222 on the connecting column 22, so that the buckle 222 is accommodated in the inside of the connecting column 22, and then the avoidance groove 131 of the battery assembly 10 is aligned with the insulating member 20, so that the insulating member 20 is inserted into the battery assembly 10 and fixed to form a whole, and then installed in the box body 80 together. Of course, the insulating member 20 can also be installed in the box body 80 first, and then the battery assembly 10 is placed in the box body 80 and plugged with the insulating member 20.

[0068] In summary, according to the battery device of the invention, by setting the insulating part 20 in the box body 80 and pluggably connecting it to the battery assembly 10, the battery assembly 10 can be accommodated in the box body 80 in the storage state, and while being protected by the box body 80, the insulating part 20 is inserted between the first reed 41 and the second reed 42 to isolate the first reed 41 and the second reed 42, preventing the series circuit from forming a closed loop, so that the battery assembly 10 will not self-discharge before being taken out of the box body 80, avoiding the doctor from running out of power in the battery assembly 10 during use and being unable to perform surgery. When surgery is required, the doctor takes the battery assembly 10 out of the box body 80 and installs it on the surgical instrument. At the same time, the insulating part 20 is separated from the battery assembly 10, and the first reed 41 and the second reed 42 are in contact to form a closed loop in the series circuit. The battery assembly 10 begins to self-discharge through the discharge circuit, thereby self-discharging while ensuring the normal use of the battery assembly 10, ensuring that the surgery can be carried out normally and meeting environmental protection requirements.
