[0002] This disclosure claims priority to Chinese Patent Application No. 202421805037.7, filed on July 29, 2024, by Guangdong Bomai Medical Technology Co., Ltd., entitled "A Self-Consuming Battery Compartment Assembly and Medical Device", and Chinese Patent Application No. 202421806492.9, filed on July 29, 2024, by Guangdong Bomai Medical Technology Co., Ltd., entitled "A Self-Consuming Board, Self-Consuming Battery Compartment Device and Medical Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure belongs to the field of medical device technology, and relates to, but is not limited to, a self-consuming battery compartment assembly and a medical device. Background Technology

[0004] With the rapid development of electronic technology, many medical devices have begun to rely on battery power to perform their functions, such as cutters, grippers, and suture devices. Battery-powered surgical instruments also encompass non-motorized tools, such as radio frequency (RF) cutters or coagulants, ultrasonic cutters or coagulants, and laser cutters or coagulants. The batteries in these active medical devices must not only provide a stable and reliable power supply but also maintain sufficient charge during use to ensure the device functions properly. Most of these medical devices are single-use and equipped with disposable batteries.

[0005] Disposable batteries may retain a significant amount of residual charge after use. If discarded without proper disposal, they could pose a potential threat to the environment and human health. Improper handling during prolonged storage or improper disposal can lead to excessive internal pressure, potentially causing explosions and releasing harmful substances that endanger the environment and human health. Therefore, proper disposal of used batteries is a crucial step.

[0006] Therefore, appropriate measures must be taken to handle disposable batteries used in disposable medical devices to reduce potential risks. One feasible method is to allow the battery to deplete its charge naturally, thereby reducing the internal charge and potential hazards. This can be done by placing the disposable medical device in a safe environment and allowing it to continue operating until the battery is depleted; however, this method is inefficient in terms of energy consumption.

[0007] Based on this, the present disclosure provides a novel self-consuming battery compartment assembly and medical device to overcome the above-mentioned defects.

[0057] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this disclosure.

[0058] The present disclosure is described in detail below with reference to Figures 1 to 14 and specific embodiments:

[0059] It should be noted that in the above and following descriptions, "proximal" usually refers to the end of the medical device that is close to the operator during normal operation, while "distal" usually refers to the end of the medical device that first enters the patient's body during normal operation.

[0060] As shown in Figure 2-14, this disclosure provides a self-consuming battery compartment assembly, which includes:

[0061] As shown in Figure 6, the loading component 1 has a hollow receiving cavity 10, four battery mounting positions 11 and a partition position 12. The hollow receiving cavity 10 is opened along its length direction. The four battery mounting positions 11 are respectively arranged at the four corners of the cross-section of the loading component 1. The partition position 12 serves to block and disconnect.

[0062] Battery pack 2, which includes four batteries 20, which are respectively arranged on battery mounting positions 11 at the four corners of the loading member 1, and each battery 20 is arranged in the opposite direction to the adjacent battery 11, that is, the electrodes are opposite.

[0063] Self-consuming power component 3, the self-consuming power component 3 is disposed at the far end of the loading component 1, and has a connected state and a non-connected state;

[0064] Insert rod 4, which is used to be inserted into the hollow receiving cavity 10 of the loading member 1;

[0065] When the insert 4 is not inserted into the hollow cavity 10 of the loading component 1, the self-consuming power component 3 is located at the partition position 12 of the loading component 1. The self-consuming power component 3 is disconnected from the cathode and anode of the battery 20 through the partition position 12 of the loading component 1, so that the self-consuming power component 3 is in a non-connected state and no self-consuming power circuit is formed, as shown in Figures 11 and 12.

[0066] When the insert 4 is inserted into the hollow cavity 10 of the loading component 1, the insert 4 pushes the self-consuming power assembly 3 inward. The self-consuming power assembly 3 moves to the far end of the loading component 1 and moves to a position away from the partition position 12 of the loading component 1. The self-consuming power assembly 3 contacts and connects with the cathode and anode of the battery 20, so that the self-consuming power assembly 3 is in a connected state and forms a self-consuming power closed loop, as shown in Figure 13; Figure 14 shows a schematic diagram of the connection circuit between the self-consuming power assembly 3 and the battery pack 2.

[0067] This disclosure discloses a self-discharging battery compartment assembly that controls the connectivity of the self-discharging component 3 by inserting or deleting the insert rod 4, thus achieving flexible control over the battery's power consumption process. When self-discharging is not required, the self-discharging component 3 is in a disconnected state, avoiding unnecessary power consumption. When self-discharging is needed, inserting the insert rod 4 connects the self-discharging component 3, making the operation simple and highly controllable. This design helps improve the efficiency and safety of disposable battery disposal, effectively reducing the environmental and health risks caused by improperly disposed batteries.

[0068] Furthermore, as shown in Figure 9, the self-consuming power assembly 3 includes a support plate 30, a first resistor 31, a second resistor 32, a first contact spring 33, a second contact spring 34, a third contact spring 35, and a fourth contact spring 36.

[0069] Both the first resistor 31 and the second resistor 32 are mounted on the support plate 30;

[0070] The first contact spring 33 and the second contact spring 34 are disposed at one end of the support plate 30 and are arranged symmetrically; the third contact spring 35 and the fourth contact spring 36 are disposed at the other end of the support plate 30 and are also arranged symmetrically, together forming the self-consuming power assembly 3.

[0071] The first contact spring 33, the second contact spring 34, the third contact spring 35 and the fourth contact spring 36 are used to make contact with the corresponding cathode and anode of the battery 20 to form a self-consuming closed loop and realize the connected state of the self-consuming component 3.

[0072] By strategically arranging multiple contact springs and resistors on the support plate 30, a stable and efficient self-discharge path is formed. This design not only ensures current stability during self-discharge but also improves contact reliability, enabling the self-discharge component 3 to accurately and efficiently connect to the battery electrodes and perform power dissipation operations. The symmetrically distributed contact spring design ensures more even contact with the battery electrodes, reducing the risk of unstable energy consumption or ineffective power dissipation due to poor contact. Simultaneously, the multiple resistors help regulate and control the self-discharge rate to accommodate different types and remaining battery capacity, thereby improving the versatility and practicality of the self-discharge component 3.

[0073] It should be noted that the specific resistance values ​​of the first resistor 31 and the second resistor 32 in this embodiment may vary depending on the specific implementation, and are not specifically limited here. In practical applications, the resistance values ​​of the first resistor 31 and the second resistor 32 are generally around 100 ohms. Of course, the resistance values ​​of the first resistor 31 and the second resistor 32 depend on the capacity, voltage, and required time of the battery pack 2. For example, in some embodiments, the battery capacity of the battery pack 2 is 1500mAh, the voltage level is 6VDC, and the target consumption time is calculated to be 24 hours. It can be calculated that a current of 0.0625A is required, and based on this current, the resistance value of the first resistor 31 and the second resistor 32 is calculated to be 96 ohms.

[0074] For example, the first contact spring 33, the second contact spring 34, the third contact spring 35, and the fourth contact spring 36 can adopt the same structure. Using contact springs with the same structure is beneficial for mass production and cost reduction. Each contact spring includes a connecting plate portion 331 that is inserted and mounted on the support plate 30, and an elastic contact portion 332 that is connected to the connecting plate portion 331.

[0075] The elastic contact portion 332 can have various shapes. For example, the elastic contact portion 332 can be an outwardly convex arc shape, as shown in Figure 9. Alternatively, the elastic contact portion 332 can be bent inward, making the first contact spring 33, the second contact spring 34, the third contact spring 35, and the fourth contact spring 36 L-shaped, as shown in Figure 10. This disclosure does not limit the specific shape of the L-shape. For example, it can include only a vertical edge and a horizontal edge connected to the vertical edge, or it can include a vertical edge and a C-shaped edge connected to the vertical edge, or it can include a vertical edge and a V-shaped edge connected to the vertical edge. Exemplary designs can be created by those skilled in the art based on actual conditions, and all of these fall within the protection scope of this disclosure.

[0076] The flexible contact part 332 features diverse shape designs, increasing its flexibility and adaptability in contact with battery electrodes. Both the outwardly convex arc shape and the L-shaped design provide a certain degree of elastic cushioning, offering more contact points and surfaces when in contact with battery electrodes. This reduces the risk of circuit failure due to poor contact, ensuring stability and reliability during contact. Simultaneously, the L-shaped design, with its various bending shapes, can adapt to various complex and limited space layouts. In short, this flexible and versatile design allows the contact spring to effectively achieve good contact with battery electrodes under various complex operating conditions, ensuring smooth self-discharge processes and providing more possibilities for product optimization and improvement.

[0077] For example, as shown in Figures 7, 8, 11, 12, and 13, each of the four battery sections 20 is provided with a metal connecting piece 21, and the four metal connecting pieces 21 are respectively connected to the anode and cathode of the corresponding loading component 1 near the end.

[0078] In the four battery cells 20, the cathodes and anodes of any two adjacent battery cells 20 located at the far end of the loading member 1 are connected to form two sets of battery strings connected in series. This disclosure does not limit how to achieve the connection between the cathodes and anodes of two adjacent battery cells at the far end of the loading member 1. For example, in this embodiment, two connecting pieces 22 are provided to achieve the connection between the anodes and cathodes of adjacent batteries located at the far end of the loading member.

[0079] When the insert 4 is inserted, the elastic contact portion 332 of the self-consuming power component 3 contacts and connects with the corresponding metal connecting piece 21, so that the self-consuming power component 3 is in a connected state.

[0080] The metal connecting piece 21 includes a flat portion 211 and a bent portion 212. The flat portion 211 is disposed along the length of the battery and fits against the outer wall surface of the battery; the flat portion 211 is used to contact and connect with the elastic contact portion 332 of the self-consuming component 3 to form a self-consuming closed loop. The flat portion 211 is bent towards the battery at the proximal end of the loading member 1 to form the bent portion 212, which is connected to the cathode or anode of the battery at the proximal end of the loading member 1.

[0081] In this embodiment, the length of the flat portion 211 of the metal connecting piece 21 is approximately equal to the length of the battery 20.

[0082] The flat portion 211 is used for contact connection with the self-consuming power assembly 3, ensuring the smooth formation of the self-consuming power circuit and enabling the self-consuming power process to proceed reliably. The bent portion 212 is designed to achieve effective connection with the battery electrodes, and this connection method is simple, stable, and easy to install and maintain. The overall design allows the metal connecting piece 21 to establish a stable and efficient electrical connection channel between the battery and the self-consuming power assembly, ensuring the normal operation and performance of the entire self-consuming power battery compartment assembly.

[0083] Furthermore, as shown in Figure 3, the self-consuming battery compartment assembly also includes a power supply connection part 5.

[0084] The power supply connection part 5 is disposed on the insertion rod 4. When the insertion rod 4 is inserted into the hollow receiving cavity 10 of the loading member 1, the power supply connection part 5 is connected to the battery pack 2 for external power supply. It should be noted that the specific structure of the power supply connection part 5 is not limited in this disclosure, and can be designed by those skilled in the art according to the actual situation, as long as it can achieve communication with the battery pack 2 and thus achieve external power supply.

[0085] When the battery is fully charged, the self-consuming battery compartment assembly with the power supply connection part 5 can be inserted into the corresponding device. This not only provides power support for external devices or systems but also meets its own power consumption needs. When the self-consuming battery compartment assembly is removed, it can still discharge until the battery is depleted.

[0086] As shown in Figures 15-18, this disclosure also provides a self-consuming power assembly 3, which is provided with a resistor 300, an elastic sheet 310, and a metal-coated contact 320 disposed on one side.

[0087] The self-consuming component 3 also has a plug hole. The fixed end 311 of the elastic piece 31 is located at the plug hole of the self-consuming component 3 and is electrically connected to the first end 301 of the resistor 300. The opening and closing end 312 of the elastic piece 310 has at least an initial state of being attached to the non-metallic coating contact side of the self-consuming component 3 and a connected state of being connected to the metallic coating contact 320 of the metallic coating contact side of the self-consuming component 3.

[0088] In the initial state, the opening and closing end of the elastic sheet 310 is attached to the non-metallic coating contact side of the self-consuming component 3, and the current cannot pass through, so the self-consuming component 3 is in a non-connected state.

[0089] When in the connected state, the opening and closing end of the elastic sheet 310 is connected to the metal-coated contact 320 on the metal-coated contact side of the self-consuming component 3, and the current forms a circuit through the resistor 300. The self-consuming component 3 is in the connected state and realizes self-consuming power.

[0090] In practical application, the self-consuming power assembly 3 disclosed herein has its second end 302 of the resistor 300 and the metal-coated contact 320 connected to the anode and cathode of the battery 20, respectively. The flexible switching of the connected state is achieved through the design of the elastic sheet 310. The working state of the self-consuming power assembly 3 is controlled by connecting its open / closed end 312 to different positions. The self-consuming power assembly 3 can perform self-powering when needed, effectively solving the potential hazards caused by residual battery power in disposable medical devices and reducing environmental pollution from discarded batteries.

[0091] Meanwhile, without the need for complicated additional operations or equipment, the automatic consumption of battery power can be achieved solely through the structural design of the self-consuming power component 3, simplifying the processing steps. Compared with other complex battery processing methods, this self-consuming power component design is more cost-effective, reducing the overall processing cost of disposable medical devices.

[0092] It should be noted that the specific resistance value of resistor 300 in this disclosure may vary depending on the specific implementation. In practical applications, the resistance value of resistor 300 is generally around 48 ohms. Of course, the resistance value of resistor 300 depends on the capacity, voltage, and required duration of the battery pack 2. For example, in some embodiments, the battery pack 2 has a battery capacity of 1500mAh and a voltage level of 6VDC. Calculated with a target consumption time of 24 hours, a current of 0.125A is required, and based on this current, the resistance value of resistor 300 is calculated to be 48 ohms.

[0093] Furthermore, the opening and closing end 312 of the elastic sheet 310 is bent into an arc shape. This arc-shaped opening and closing end provides a smoother transition when connected to the metal-coated contact 320 or the non-metal-coated contact side, reducing the impact and instability at the moment of contact and ensuring the stability and reliability of the conduction and disconnection processes. Simultaneously, the arc-shaped surface increases the contact area when in contact with the contact point, thereby reducing contact resistance and improving the efficiency of current flow, which helps to more effectively achieve the self-discharge process.

[0094] As shown in Figures 15-19, this disclosure provides another self-consuming battery compartment assembly, which includes:

[0095] The loading component 1 has a hollow receiving cavity 10 and four battery mounting positions 11. The hollow receiving cavity 10 is opened along its length direction, and the four battery mounting positions 11 are respectively arranged at the four corners of the cross-section of the loading component 1.

[0096] Battery pack 2 includes four batteries 20, which are respectively arranged on battery mounting positions 11 at the four corners of the loading member 1. Each battery is arranged in the opposite direction to the adjacent battery 20. The anode and cathode of two adjacent batteries 20 located at the far end of the loading member 1 are interconnected to form two sets of battery strings connected in series. For example, the anode and cathode of two adjacent batteries 20 are connected by a connecting piece 22 to form a battery string.

[0097] Self-consuming power component 3, the self-consuming power component 3 is the self-consuming power component mentioned above, is disposed at the far end of the loading member 1 and attached to the battery pack 2; the second end 302 of the resistor 300 and the metal coating contact 320 are respectively used to connect to the two electrodes of the battery string located at the far end of the loading member 1.

[0098] Insert rod 4 is used to be inserted into the hollow receiving cavity 10 of the loading component 1, and a power supply connection part 5 is provided on the insert rod 4. When the insert rod 4 is inserted into the hollow receiving cavity 10 of the loading component 1, the power supply connection part 5 is connected to the two electrodes of the battery pack 2 located near the loading component 1 for external power supply.

[0099] When the insert 4 is not inserted into the loading member 1, the elastic sheet 310 is in the initial state, and the opening and closing end 312 of the elastic sheet 310 is attached to the non-metallic coating contact side of the self-consuming component 3.

[0100] When the insert 4 is inserted into the loading member 1, the elastic piece 310 is in the open state, and the opening and closing end 312 of the elastic piece 310 is placed on the metal coating contact side of the self-consuming component 3, but is disconnected from the metal coating contact 320.

[0101] When the insert 4 is withdrawn from the loading member 1, the elastic sheet 310 is in a connected state, and the opening and closing end 312 of the elastic sheet 310 is connected to the metal-coated contact 320 of the self-consuming component 3.

[0102] The self-consuming battery compartment assembly disclosed herein has the following characteristics:

[0103] When the insertion rod 4 is inserted into the loading component 1, the power supply connection 5 is connected to the battery pack 2, enabling external power supply. However, the elastic sheet 310 is in a disconnected state and does not perform self-power consumption. When the insertion rod 4 is removed from the loading component 1, the power supply connection 5 is disconnected from the battery pack 2, and the elastic sheet 310 is in a connected state, thus performing self-power consumption. This application can automatically switch between external power supply and self-power consumption based on the insertion and removal states of the insertion rod 4, achieving intelligent power management of the battery. It is particularly suitable for situations where the battery pack 2 has insufficient power. When using external power supply, no power is consumed. After removing the insertion rod 4, the remaining power in the battery pack 2 is self-powered by the self-power consumption component 3, effectively solving the potential hazards caused by the remaining power in disposable medical devices and reducing environmental pollution from discarded batteries.

[0104] Furthermore, each of the four battery sections 20 is provided with a metal connecting piece 21, and the four metal connecting pieces 21 are respectively connected to the anode and cathode of the corresponding loading component 1 near the end;

[0105] The second end 302 of the resistor 300 of the self-consuming power assembly 3 and the metal-coated contact 320 are used to contact and connect with the corresponding metal connecting piece 21, realizing the connection with the two electrodes and forming a self-consuming power circuit; when the elastic piece 310 is in the connected state, the battery 20 consumes power. At the same time, the metal connecting piece 21 is also used to electrically connect with the power supply connection part 5 to realize the external power supply of the battery 20. The design of the metal connecting piece 21 can establish a stable and efficient electrical connection channel between the battery and the self-consuming power assembly, ensuring the normal operation and performance of the entire self-consuming power battery compartment assembly.

[0106] Furthermore, as shown in FIG3, the insertion rod 4 includes a fixing plate portion 40 and an insertion rod portion 41 vertically mounted on the fixing plate portion 40. The insertion rod portion 41 is inserted into the hollow receiving cavity 10 of the loading member 1, and the fixing plate portion 40 abuts against the end of the battery pack 2.

[0107] The way the insertion rod 41 cooperates with the loading component 1 ensures the stability and accuracy of the insertion action, allowing the insertion rod 41 to be smoothly and firmly inserted into the loading component 1, avoiding shaking or dislocation during use, thus ensuring the reliability of the entire structural connection. The fixing plate 40's abutment against the end of the battery pack 2 visually indicates to the operator that the installation is in place, helping to improve installation efficiency and accuracy, and reducing malfunctions and safety hazards caused by improper installation.

[0108] For example, the fixed plate portion 40 has an L-shaped cross-section and includes a fixed plate body 401 and a connecting plate 402 extending perpendicularly to the fixed plate body 401 away from the insertion portion. Mounting holes are provided on the connecting plate 402 for external connection. For example, when the self-consuming battery compartment assembly is installed on the handle, a fixed connection between it and the handle is achieved through the mounting holes on the connecting plate 402. Simultaneously, the connecting plate 402 facilitates the operator's gripping of the connecting plate 402 to insert the insertion rod 4 into the hollow receiving cavity 10 of the loading component 1.

[0109] For example, strip-shaped protrusions 411 are provided on both the upper and lower sides of the insertion rod portion 41 for positioning purposes.

[0110] Correspondingly, a positioning groove 13 is provided on the loading component 1. The strip-shaped protrusion 411 of the insertion rod portion 41 is inserted into the positioning groove 13 of the loading component 1 to achieve positioning and installation of the insertion rod 4. The strip-shaped protrusion 411 on the insertion rod portion 41 cooperates with the positioning groove 13 on the loading component 1 to ensure the accuracy of the insertion position of the insertion rod 4 and avoid poor contact or functional failure caused by installation deviation.

[0111] Furthermore, as shown in Figure 4, a battery pack housing 23 can be added to the battery pack 2. Both ends of the battery pack housing 23 are equipped with barbed structures 24 for external connection. For example, when the self-consuming battery compartment assembly is installed on the handle, the barbed structures 24 achieve a fixed connection with the handle. The battery pack housing 23 protects the battery pack 2 from damage caused by external factors. The barbed structures 24 at both ends ensure the safety and stability of the battery pack 2 during installation.

[0112] Based on the aforementioned self-consuming battery compartment assembly, this disclosure also provides a medical device, as shown in Figure 1, which includes a handle portion 7, a functional portion 6 installed at one end of the handle portion 7, and the aforementioned self-consuming battery compartment assembly installed at the other end of the handle portion 7. The self-consuming battery compartment assembly is electrically connected to the functional portion 6 to supply power to it. Before use, the self-consuming battery compartment assembly is assembled to the other end of the handle portion, and a fixed connection between it and the handle is achieved through the barb structure 24 and the mounting holes on the connecting plate 402. At this time, the power supply circuit diagram of the handle portion is shown in Figure 5.

[0113] For example, handheld active medical devices are typically equipped with a disposable battery, placed at the proximal end of the handle, with the distal end serving as the functional end. In this embodiment, for a disposable shockwave balloon, the electrode built into the distal end of the balloon acts as a shockwave generator to achieve the corresponding function. The aforementioned self-consuming battery compartment assembly is configured at the proximal end of the handle, and a pulse generator is also provided in the handle portion. The self-consuming battery compartment assembly is electrically connected to the pulse generator, and the pulse generator is connected to the shockwave generator (i.e., the balloon) via a cable. Typically, the pulse generator boosts the voltage provided by the battery pack 2 in the self-consuming battery compartment assembly once or twice, bringing it to 2 to 4KV to provide power to the handheld active medical device. This medical device incorporates all the technical solutions of the aforementioned self-consuming battery compartment assembly and possesses at least all the advantages of the self-consuming battery compartment assembly, which will not be elaborated further here.

[0114] The present disclosure has been further described above with reference to specific embodiments. However, it should be understood that the exemplary description herein should not be construed as limiting the substance and scope of the present disclosure. Various modifications made to the above embodiments by those skilled in the art after reading this specification are within the scope of protection of this disclosure.
