[0001] Cross-reference to related applications

[0002] The present disclosure claims priority to Chinese Patent Application No. 202421805037.7, filed on July 29, 2024, entitled “Self-consumption battery cartridge assembly and medical instrument”, and Chinese Patent Application No. 202421806492.9, filed on July 29, 2024, entitled “Self-consumption battery plate, self-consumption battery cartridge device and medical instrument”, both of which are owned by Guangdong Boma Medical Technology Co., Ltd., and the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] The present disclosure belongs to the technical field of medical instruments, and relates to a self-consumption battery cartridge assembly and a medical instrument. BACKGROUND

[0004] With the rapid development of electronic technology, many medical instruments begin to rely on battery power to realize their own functions, such as cutters, graspers, and suturing devices. Battery-powered surgical instruments also cover non-motor-driven tools, such as radio frequency (RF) cutters or coagulators, ultrasonic cutters or coagulators, and laser cutters or coagulators. The batteries of these active medical instruments not only need to provide stable and reliable power supply, but also need to maintain sufficient power during use to ensure that the equipment can operate normally. Most of these similar medical instruments are disposable and are equipped with disposable batteries.

[0005] After use, the disposable batteries may still have a large amount of residual power. If they are discarded without proper treatment, they are likely to pose potential hazards to the environment and human health. If these batteries are not properly disposed of, they may have high internal pressure due to long-term storage or improper disposal, and even cause serious accidents such as explosions, releasing harmful substances and posing a threat to the environment and human health. Therefore, it is extremely important to dispose of used batteries.

[0006] Therefore, for disposable batteries used in disposable medical instruments, appropriate treatment methods must be taken to reduce potential risks. One possible method is to let the battery self-discharge to reduce internal charge and thus reduce its potential danger. This can be achieved by placing the disposable medical instrument in a safe environment and allowing it to run continuously until the battery is discharged, but this method has low power consumption efficiency.

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

DETAILED DESCRIPTION

[0057] The technical solutions in the embodiments of the present disclosure will be described in detail below with reference to the drawings in the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the present disclosure.

[0058] The present disclosure will be described in detail below with reference to Figs. 1 to 14 and specific embodiments:

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

[0060] As shown in FIG. 2-14, the present disclosure provides a self-consumption battery compartment assembly, which comprises:

[0061] A loading piece 1, as shown in FIG. 6, has a hollow accommodating cavity 10, four battery mounting positions 11, and a partition position 12. The hollow accommodating 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 piece 1. The partition position 12 has a blocking and disconnecting function.

[0062] A battery pack 2, which comprises four batteries 20. The four batteries 20 are respectively arranged on the battery mounting positions 11 at the four corners of the loading piece 1. Each battery 20 is arranged reversely to the adjacent battery 11, i.e., the electrodes are opposite.

[0063] A self-consumption assembly 3, which is arranged at the distal end of the loading piece 1 and has a connected state and a non-connected state.

[0064] A plug rod 4, which is used for being inserted into the hollow accommodating cavity 10 of the loading piece 1.

[0065] When the plug rod 4 is not inserted into the hollow accommodating cavity 10 of the loading piece 1, the self-consumption assembly 3 is located at the partition position 12 of the loading piece 1. The self-consumption assembly 3 is disconnected from the cathode and anode of the battery 20 through the partition position 12 of the loading piece 1, so that the self-consumption assembly 3 is in a non-connected state and does not form a self-consumption circuit, as shown in FIGS. 11 and 12.

[0066] When the plug rod 4 is inserted into the hollow accommodating cavity 10 of the loading piece 1, the plug rod 4 pushes the self-consumption assembly 3 inwardly. The self-consumption assembly 3 moves to the distal end of the loading piece 1 and moves away from the partition position 12 of the loading piece 1. The self-consumption assembly 3 is connected to the cathode and anode of the battery 20, so that the self-consumption assembly 3 is in a connected state and forms a self-consumption closed loop, as shown in FIG. 13. As shown in FIG. 14, it is a schematic diagram of the connection circuit between the self-consumption assembly 3 and the battery pack 2.

[0067] The self-consumption battery compartment assembly controls the communication state of the self-consumption assembly 3 by inserting or not inserting the insertion rod 4, thereby achieving flexible control over the battery consumption process. When the self-consumption of the battery is not needed, the self-consumption assembly 3 is in a non-communication state, thereby avoiding unnecessary power consumption. When self-consumption processing is needed, inserting the insertion rod 4 can make the self-consumption assembly 3 communicate, which is simple to operate and has strong controllability. This design helps to improve the efficiency and safety of disposable battery processing, effectively reducing the environmental and health risks caused by improper battery processing.

[0068] Further, as shown in FIG. 9, the self-consumption 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] The first resistor 31 and the second resistor 32 are both mounted on the support plate 30;

[0070] The first contact spring 33 and the second contact spring 34 are arranged at one end of the support plate 30, and are symmetrically arranged; the third contact spring 35 and the fourth contact spring 36 are arranged at the other end of the support plate 30, and are also symmetrically arranged, together forming the self-consumption 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 contact and connect with the cathode and anode of the corresponding battery 20, forming a self-consumption closed loop, thereby realizing the communication state of the self-consumption assembly 3.

[0072] By reasonably arranging multiple contact springs and resistors on the support plate 30, a stable and effective self-consumption path is formed. This design not only ensures the stability of the current during self-consumption, but also improves the reliability of the contact, so that the self-consumption assembly 3 can accurately and efficiently realize the connection with the battery electrode and the power consumption operation. The symmetrical distribution of the contact springs makes the contact with the battery electrode more balanced, reducing the risk of unstable energy consumption or ineffective power consumption caused by poor contact. At the same time, the arrangement of multiple resistors helps to adjust and control the rate of self-consumption, so as to adapt to different types and remaining power of the battery, thereby improving the versatility and practicality of the self-consumption assembly 3.

[0073] It should be noted that the specific resistance values of the first resistor 31 and the second resistor 32 in the embodiments of the present disclosure can be changed based on specific implementation, which is not specifically limited here. In actual application, the resistance values of the first resistor 31 and the second resistor 32 are generally about 100 ohms. Of course, the resistance values of the first resistor 31 and the second resistor 32 depend on the capacity, voltage of the battery pack 2 and the required length of time. For example, in some embodiments, the battery capacity of the battery pack 2 is 1500 mAh, the voltage level is 6VDC, and the target consumption time is 24 hours, which can be calculated to generate a current of 0.0625A, and the resistance values of the first resistor 31 and the second resistor 32 are calculated to be 96 ohms according to the current.

[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, and the contact springs with the same structure are beneficial to batch production and cost reduction. Each contact spring includes a connecting plate part 331 inserted and mounted on the support plate 30, and an elastic contact part 332 connected with the connecting plate part 331.

[0075] The shape of the elastic contact part 332 can be various, for example, the elastic contact part 332 is in the form of an outwardly convex circular arc, as shown in FIG. 9. Alternatively, the elastic contact part 332 is inwardly bent, so that the first contact spring 33, the second contact spring 34, the third contact spring 35 and the fourth contact spring 36 are in the form of L, as shown in FIG. 10. The present disclosure does not limit the specific shape of the L type, which can include only a vertical edge, a horizontal edge connected with the vertical edge, or a C-shaped edge connected with the vertical edge, or a V-shaped edge connected with the vertical edge. For example, the shape can be designed by those skilled in the art according to actual conditions, which all belong to the protection scope of the present disclosure.

[0076] The various shape designs of the elastic contact part 332 increase the flexibility and adaptability of the contact with the battery electrode. The designs of the outwardly convex circular arc and the L type can provide certain elastic buffering, and can provide more contact points and contact surfaces when contacting the battery electrode, thereby reducing the risk of circuit failure caused by poor contact and ensuring the stability and reliability of the contact. At the same time, the design of the L type, such as different bending shapes, can also adapt to various complex and limited space layouts. In summary, such flexible and variable design enables the contact spring to effectively achieve good contact with the battery electrode in various complex working conditions, ensures the smooth progress of the self-consumption process, and also provides more possibilities for the optimization and improvement of the product.

[0077] As shown in FIGS. 7, 8, 11, 12, and 13, each of the four batteries 20 is provided with a metal connecting piece 21, and the four metal connecting pieces 21 are respectively connected to the anode and the cathode of the proximal end of the carrier 1.

[0078] The cathode and the anode of any two adjacent batteries 20 at the distal end of the carrier 1 are connected to form two groups of battery strings in series. In the present disclosure, how to realize the connection between the cathode and the anode of the adjacent batteries at the distal end of the carrier 1 is not limited. In the present embodiment, two connecting pieces 22 are provided to realize the connection between the cathode and the anode of the adjacent batteries at the distal end of the carrier.

[0079] When the insertion rod 4 is inserted, the elastic contact part 332 of the self-consumption power assembly 3 is respectively connected to the corresponding metal connecting piece 21 to make the self-consumption power assembly 3 in a connected state.

[0080] The metal connecting piece 21 includes a flat part 211 and a bent part 212. The flat part 211 is arranged along the length direction of the battery and is attached to the outer wall surface of the battery. The flat part 211 is used to be connected to the elastic contact part 332 of the self-consumption power assembly 3 to form a self-consumption power closed loop. The flat part 211 is bent towards the battery at the proximal end of the carrier 1 to form the bent part 212, which is connected to the cathode or the anode of the battery at the proximal end of the carrier 1.

[0081] In the present embodiment, the length of the flat part 211 of the metal connecting piece 21 is substantially equal to the length of the battery 20.

[0082] The flat part 211 is used to be connected to the self-consumption power assembly 3 to ensure the smooth formation of the self-consumption power loop and make the self-consumption process reliably proceed. The design of the bent part 212 realizes the effective connection with the battery electrode, and this connection method is simple and stable, which is convenient for installation and maintenance. The overall design enables the metal connecting piece 21 to establish a stable and efficient electrical connection channel between the battery and the self-consumption power assembly, and ensures the normal operation and performance of the entire self-consumption power battery compartment assembly.

[0083] Further, as shown in FIG. 3, the self-consumption power battery compartment assembly further includes a power supply connecting part 5.

[0084] The power supply connecting part 5 is arranged on the insertion rod 4. When the insertion rod 4 is inserted into the hollow accommodating cavity 10 of the carrier 1, the power supply connecting part 5 is connected to the battery group 2 for external power supply. It should be noted that the specific structure of the power supply connecting part 5 is not limited in the present disclosure, which can be designed by those skilled in the art according to the actual situation. As long as the connection between the battery group 2 and the power supply connecting part 5 can be realized, the external power supply can be realized.

[0085] When the battery is fully charged, the self-consumption battery compartment assembly with power supply connection part 5 can be inserted into the corresponding device, which not only provides power support for external equipment or system, but also meets the self-consumption demand. When the self-consumption battery compartment assembly is removed, the self-consumption battery compartment assembly can still discharge until the battery is exhausted.

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

[0087] The self-consumption assembly 3 is also provided with a plug-in hole, and the fixed end 311 of the elastic sheet 310 is arranged at the plug-in hole of the self-consumption assembly 3 and electrically connected with the first end 301 of the resistor 300; the opening and closing end 312 of the elastic sheet 310 has at least an initial state of being attached to the non-metal coating contact side of the self-consumption assembly 3 and a communication state of being connected with the metal coating contact 320 of the metal coating contact side of the self-consumption assembly 3.

[0088] That is, in the initial state, the opening and closing end of the elastic sheet 310 is attached to the non-metal coating contact side of the self-consumption assembly 3, and the current cannot pass through, and the self-consumption assembly 3 is in a non-communication state;

[0089] In the communication state, the opening and closing end of the elastic sheet 310 is connected with the metal coating contact 320 of the metal coating contact side of the self-consumption assembly 3, the current passes through the resistor 300 to form a loop, the self-consumption assembly 3 is in a communication state, and self-consumption is realized.

[0090] In the present disclosure, the self-consumption assembly 3, in actual application, the second end 302 of the resistor 300 and the metal coating contact 320 are respectively connected with the anode and cathode of the battery 20, and the flexible switching of the communication state is realized through the design of the elastic sheet 310, and the working state of the self-consumption assembly 3 is controlled through the connection of the opening and closing end 312 with different positions. The self-consumption assembly 3 can perform self-consumption processing when needed, effectively solving the potential harm caused by the remaining battery capacity in disposable medical devices and reducing the pollution of waste batteries to the environment.

[0091] At the same time, without complex additional operations or equipment, the automatic consumption of battery capacity can be realized only through the structural design of the self-consumption assembly 3, simplifying the processing steps; compared with other complex battery processing methods, the design of the self-consumption assembly has more advantages in cost, reducing the overall processing cost of disposable medical devices.

[0092] It should be noted that the specific resistance of the resistance member 300 in the present disclosure can be changed based on the specific implementation. In practical applications, the resistance of the resistance member 300 is generally about 48 ohms. Of course, the resistance of the resistance member 300 depends on the capacity, voltage of the battery pack 2 and the required length of time. For example, in some embodiments, the battery capacity of the battery pack 2 is 1500 mAh, the voltage level is 6VDC, and the target consumption time is 24 hours, which can result in a current of 0.125A, and the resistance of the resistance member 300 is calculated to be 48 ohms according to the current.

[0093] Further, the opening and closing end 312 of the elastic sheet 310 is bent into an arc shape. When the arc-shaped opening and closing end is connected to the metal-coated contact 320 or the non-metal-coated contact, it can provide a smoother transition, reduce the impact and instability in the contact moment, and ensure the stability and reliability of the on and off process. At the same time, the arc-shaped surface can increase the contact area when contacting the contact, thereby reducing the contact resistance and improving the efficiency of current passing, which helps to more effectively achieve the self-consumption process.

[0094] As shown in FIGS. 15-19, the present disclosure provides another self-consumption battery compartment assembly, which comprises:

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

[0096] The battery pack 2 comprises four batteries 20. The four batteries 20 are respectively arranged on the battery mounting positions 11 at the four corners of the loading member 1. Each battery is arranged opposite to the adjacent battery 20. The anode and the cathode of the two adjacent batteries 20 at the distal end of the loading member 1 are in communication with each other, forming two groups of series-connected battery strings. For example, the anode and the cathode of the two adjacent batteries 20 are connected by a connecting sheet 22, forming a battery string.

[0097] The self-consumption assembly 3 is the self-consumption assembly described above, which is arranged at the distal end of the loading member 1 and attached to the battery pack 2. The second end 302 of the resistance member 300 is respectively connected to the two electrodes of the battery string at the distal end of the loading member 1.

[0098] The insertion rod member 4 is inserted into the hollow accommodating cavity 10 of the loading member 1. A power supply connection part 5 is arranged on the insertion rod member 4. When the insertion rod member 4 is inserted into the hollow accommodating cavity 10 of the loading member 1, the power supply connection part 5 is connected to the two electrodes of the battery pack 2 at the proximal end of the loading member 1, for external power supply.

[0099] When the insertion rod 4 is not inserted into the loading part 1, the elastic sheet 310 is in an initial state, and the open end 312 of the elastic sheet 310 is attached to the non-metallic coating contact side of the self-consumption power component 3;

[0100] When the insertion rod 4 is inserted into the loading part 1, the elastic sheet 310 is in a disconnected state, and the open end 312 of the elastic sheet 310 is placed on the metallic coating contact side of the self-consumption power component 3, but is disconnected from the metallic coating contact 320;

[0101] When the insertion rod 4 is withdrawn from the loading part 1, the elastic sheet 310 is in a connected state, and the open end 312 of the elastic sheet 310 is connected to the metallic coating contact 320 of the self-consumption power component 3.

[0102] The self-consumption power battery compartment assembly of the present disclosure has the following characteristics:

[0103] When the insertion rod 4 is inserted into the loading part 1, the power supply connection part 5 is connected to the battery pack 2, realizing external power supply, while the elastic sheet 310 is in a disconnected state and does not perform self-consumption power processing. When the insertion rod 4 is withdrawn from the loading part 1, the power supply connection part 5 is disconnected from the battery pack 2, and the elastic sheet 310 is in a connected state, thereby performing self-consumption power processing. In this application, external power supply and self-consumption power processing can be automatically switched according to the insertion and withdrawal states of the insertion rod 4, realizing intelligent power management of battery power. Especially when the battery pack 2 has insufficient power, it does not consume power when used for external power supply. After removing the insertion rod 4, the remaining power of the battery pack 2 is processed by the self-consumption power component 3, effectively solving the potential hazards caused by the remaining power of the battery in disposable medical devices and reducing the environmental pollution caused by waste batteries.

[0104] Further, the four batteries 20 are each provided with a metallic connecting sheet 21, and the four metallic connecting sheets 21 are respectively connected to the anode and cathode of the proximal end of the corresponding loading part 1;

[0105] The second end 302 of the resistance 300 of the self-consumption power component 3 is used to contact and connect with the corresponding metallic connecting sheet 21, realizing the connection with the two electrodes and forming a self-consumption power circuit; when the elastic sheet 310 is in a connected state, the power consumption of the battery 20 is processed. At the same time, the metallic connecting sheet 21 is also used for electrical connection with the power supply connection part 5, realizing the external power supply of the battery 20. The design of the metallic connecting sheet 21 can establish a stable and efficient electrical connection channel between the battery and the self-consumption power component, ensuring the normal operation and performance of the entire self-consumption power battery compartment assembly.

[0106] Further, as shown in FIG. 3, the insertion rod member 4 comprises a fixed plate portion 40 and an insertion rod portion 41 vertically mounted on the fixed plate portion 40, the insertion rod portion 41 is inserted into the hollow accommodating cavity 10 of the loading member 1, and the fixed plate portion 40 abuts against the end of the battery pack 2.

[0107] The cooperation between the insertion rod portion 41 and the loading member 1 ensures the stability and accuracy of the insertion action, so that the insertion rod portion 41 can be smoothly and firmly inserted into the loading member 1, avoiding the situation of shaking or dislocation during use, thereby ensuring the reliability of the entire structure connection. The abutment of the fixed plate portion 40 against the end of the battery pack 2 intuitively prompts the operator that the installation is in place, which helps to improve the efficiency and accuracy of the installation, and reduces the failure and safety hazards caused by improper installation.

[0108] For example, the cross-sectional shape of the fixed plate portion 40 is L-shaped, comprising a fixed plate body 401 and a connecting plate 402 extending away from the insertion portion and perpendicular to the fixed plate body 401, and a mounting hole is formed on the connecting plate 402 for external connection. When the self-consumption battery compartment assembly is installed on the handle, the fixed connection between the handle and the self-consumption battery compartment assembly is realized through the mounting hole formed on the connecting plate 402. At the same time, the connecting plate 402 is convenient for the operator to grasp the connecting plate 402 to insert the insertion rod member 4 into the hollow accommodating cavity 10 of the loading member 1.

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

[0110] Correspondingly, a positioning groove 13 is formed on the loading member 1, and the strip-shaped protrusions 411 of the insertion rod portion 41 are inserted into the positioning groove 13 of the loading member 1 to realize the positioning installation of the insertion rod member 4. The cooperation between the strip-shaped protrusions 411 on the insertion rod portion 41 and the positioning groove 13 on the loading member 1 ensures the positional accuracy when the insertion rod member 4 is inserted, avoiding poor contact or functional failure caused by installation deviation.

[0111] In addition, as shown in FIG. 4, a battery pack shell 23 can also be arranged on the battery pack 2, and a barb structure 24 is arranged at both ends of the battery pack shell 23 for external connection. When the self-consumption battery compartment assembly is installed on the handle, the fixed connection between the handle and the self-consumption battery compartment assembly is realized through the barb structure 24. The battery pack shell 23 covering the battery pack 2 can protect the battery pack 2 from damage caused by external factors. The barb structures 24 at both ends ensure the safety and stability of the installation of the battery pack 2.

[0112] The self-consumption battery cartridge assembly is assembled to the other end of the handle part before use, and is fixedly connected with the handle through the reverse hook structure 24 and the mounting hole on the connecting plate 402. At this time, the power supply circuit diagram of the handle part is shown in Fig. 5.

[0113] For example, a hand-held active medical instrument is usually equipped with a disposable battery, which is placed at the proximal end of the handle, and the distal end is used as a function implementation end. In this embodiment, for a disposable shock wave balloon, the electrode built-in at the distal end of the balloon is used as a shock wave generator to realize the corresponding function. The self-consumption battery cartridge assembly mentioned above is arranged at the proximal end of the handle, and a pulse generator is arranged in the handle part. The self-consumption battery cartridge assembly is electrically connected with the pulse generator, and the pulse generator is connected with the shock wave generator (i.e. the balloon) through a cable. Usually, the pulse generator will boost the voltage provided by the battery pack 2 in the self-consumption battery cartridge assembly once or twice to reach 2-4KV, so as to provide power supply for the hand-held active medical instrument. The medical instrument contains all the technical solutions of the self-consumption battery cartridge assembly, and at least has all the advantages of the self-consumption battery cartridge assembly, which will not be described here.

[0114] The above further describes the present disclosure with the help of specific embodiments, but it should be understood that the exemplary description herein should not be understood as limiting the essence and scope of the present disclosure, and various modifications made by those skilled in the art after reading the description of the above embodiments all belong to the scope protected by the present disclosure.
