Description

Technical Field

[0002] With the rapid advancement of electronic technology, many medical devices, such as cutters, graspers, and staplers, are now powered by batteries to achieve their functions. Battery-powered surgical instruments also include non-motor-driven tools, such as RF cutters / coagulators, ultrasonic cutters / coagulators, and laser cutters / coagulators. The batteries in these active medical devices must not only provide a stable and reliable power source but also maintain sufficient charge during use to ensure proper operation. Most of these medical devices are disposable and come with disposable batteries.

[0003] Disposable batteries may still have a significant amount of residual power after use. If discarded without proper handling, they can pose potential risks to the environment and human health. Prolonged storage or improper disposal can lead to excessive internal pressure, potentially exploding, and releasing harmful substances, posing a threat to the environment and human health. Therefore, proper disposal of used batteries is crucial.

[0004] Therefore, it is crucial to adopt appropriate disposal methods for disposable batteries used in disposable medical devices to reduce potential risks. One feasible method is to allow the battery to drain itself, thereby reducing the internal charge and thus reducing its potential danger. This can be achieved by placing the disposable medical device in a safe environment and allowing it to continue operating until the battery is exhausted.

[0005] Based on this, the present invention provides a novel self-consumable battery compartment assembly and medical device to overcome the above-mentioned defects. Utility Model Content

DETAILED DESCRIPTION

[0050] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] The following is combined with Figure 1 To the attached Figure 14 And specific embodiments, the utility model is discussed in detail:

[0052] It should be noted that the "proximal end" in the above description and the following description usually refers to the end of the medical device close to the operator during normal operation, and the "distal end" usually refers to the end of the medical device that first enters the patient's body during normal operation.

[0053] like Figure 2-14 As shown, the utility model provides a self-consumable battery compartment assembly, which includes:

[0054] Loading part 1, such as Figure 6As shown, the loading member 1 has a hollow accommodating cavity 10, four battery installation positions 11 and a partition position 12. The hollow accommodating cavity 10 is opened along its length direction. The four battery installation positions 11 are respectively arranged at the four corners of the cross section of the loading member 1. The partition position 12 plays a role of blocking and disconnecting.

[0055] A battery pack 2, comprising four batteries 20, each of which is disposed on the battery mounting positions 11 at the four corners of the loading member 1, and each battery 20 is disposed opposite to the adjacent battery 11, i.e., with opposite electrodes;

[0056] A self-consumable electricity component 3, which is slidably disposed at the distal end of the loading member 1 and has a connected state and a disconnected state;

[0057] an inserting rod 4 , the inserting rod 4 being used to be inserted into the hollow receiving cavity 10 of the loading member 1 ;

[0058] When the insertion rod 4 is not inserted into the hollow accommodating cavity 10 of the loading part 1, the consumable electricity component 3 is located at the isolation position 12 of the loading part 1, and the consumable electricity component 3 is disconnected from the cathode and anode of the battery 20 through the isolation position 12 of the loading part 1, so that the consumable electricity component 3 is in a non-connected state and no consumable electricity circuit is formed. Figure 11 、 12 As shown;

[0059] When the insertion rod 4 is inserted into the hollow accommodating cavity 10 of the loading part 1, the insertion rod 4 pushes the consumable electricity component 3 inward, and the consumable electricity component 3 slides toward the far end of the loading part 1 and slides to a position away from the partition position 12 of the loading part 1. The consumable electricity component 3 is in contact with the cathode and anode of the battery 20, so that the consumable electricity component 3 is in a connected state, forming a consumable electricity closed circuit. Figure 13 As shown; Figure 14 It is a schematic diagram of the connection circuit between the self-consumable power component 3 and the battery pack 2.

[0060] The present utility model's disposable battery compartment assembly controls the connectivity of the disposable battery assembly 3 by controlling the insertion of a plug-in member 4, enabling flexible control over battery power consumption. When battery power is not required, the disposable battery assembly 3 is disconnected, preventing unnecessary power consumption. However, when power processing is required, the plug-in member 4 is inserted to connect the disposable battery assembly 3, providing ease of operation and high controllability. This design helps improve the efficiency and safety of disposable battery processing, effectively reducing the environmental and health risks associated with improper battery handling.

[0061] Further, such as Figure 9As shown, the self-consumable power component 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 .

[0062] The first resistor 31 and the second resistor 32 are both mounted on the support plate 30;

[0063] 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-consumable power component 3.

[0064] 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 to form a self-consumable power closed loop and realize the connection state of the self-consumable power component 3 .

[0065] By rationally arranging multiple contact springs and resistors on the support plate 30, a stable and effective self-consumable power path is formed. This design not only ensures current stability during the self-consumption process but also improves contact reliability, enabling the self-consumable power component 3 to accurately and efficiently connect to the battery electrodes and consume power. The symmetrically distributed contact springs ensure more balanced contact with the battery electrodes, reducing the risk of unstable energy consumption or inefficient power consumption due to poor contact. Furthermore, the provision of multiple resistors helps adjust and control the self-consumption rate to accommodate batteries of different types and remaining capacities, thereby enhancing the versatility and practicality of the self-consumable power component 3.

[0066] It should be noted that the specific resistance values ​​of the first resistor 31 and the second resistor 32 in the present invention may vary depending on the specific implementation. In practical applications, the resistance of the first resistor 31 and the second resistor 32 is generally around 100 ohms. Of course, the resistance values ​​of the first resistor 31 and the second resistor 32 depend on the capacity and voltage of the battery pack 2, as well as the required duration. For example, in some embodiments, the battery pack 2 has a battery capacity of 1500 mAh and a voltage level of 6 VDC. Based on a target duration of 24 hours, a current of 0.0625 A is required. Based on this current, the resistance values ​​of the first resistor 31 and the second resistor 32 are calculated to be 96 ohms.

[0067] Specifically, the first contact spring 33, the second contact spring 34, the third contact spring 35, and the fourth contact spring 36 have the same structure. Using the same structure facilitates mass production and reduces costs. They all include a connecting plate portion 331 that is plugged into the support plate 30 and an elastic contact portion 332 connected to the connecting plate portion 331.

[0068] The elastic contact portion 332 may have various shapes. For example, the elastic contact portion 332 may be in an outwardly convex arc shape. Figure 9 Alternatively, the elastic contact portion 332 is bent inward, so that the first contact spring 33, the second contact spring 34, the third contact spring 35, and the fourth contact spring 36 are L-shaped, as shown. Figure 10 The present invention does not limit the specific shape of the L-shape. For example, it may include only vertical edges and horizontal edges connected to the vertical edges, or include vertical edges and C-shaped edges connected to the vertical edges, or include vertical edges and V-shaped edges connected to the vertical edges. The specific design can be made by those skilled in the art according to actual conditions, and all of these fall within the scope of protection of the present invention.

[0069] The diverse shape designs of the elastic contact portion 332 increase the flexibility and adaptability of contact with the battery electrodes. Both the outwardly protruding arc shape and the L-shaped design can provide a certain degree of elastic buffering, which can provide more contact points and contact surfaces when contacting the battery electrodes, reducing the risk of circuit failure due to poor contact and ensuring stability and reliability during contact. At the same time, the L-shaped design, such as different bending shapes, can also adapt to various complex and limited space layouts. In short, this flexible and changeable design enables the contact spring to effectively achieve good contact with the battery electrodes under various complex working conditions, ensuring the smooth progress of the self-consumption process, and also providing more possibilities for product optimization and improvement.

[0070] Specifically, such as Figure 7 、 8 As shown in Figures 11, 12 and 13, the four batteries 20 are each provided with a metal connecting piece 21, and the four metal connecting pieces 21 are respectively connected to the anode and cathode at the proximal end of the corresponding loading part 1.

[0071] The cathodes and anodes of any two adjacent batteries 20 at the far end of the loading part 1 are connected to each other to form two groups of battery strings connected in series. The present invention does not limit how to achieve the connection between the cathodes and anodes of the two adjacent batteries at the far end of the loading part 1. For example, in this embodiment, two connecting pieces 22 are provided to achieve the connection between the cathodes and anodes of the adjacent batteries at the far end of the loading part.

[0072] When the inserting rod 4 is inserted, the elastic contact portions 332 of the consumable electrical component 3 are respectively in contact and connected with the corresponding metal connecting pieces 21 , so that the consumable electrical component 3 is in a connected state.

[0073] The metal connecting piece 21 includes a flat portion 211 and a bent portion 212. The flat portion 211 extends along the length of the battery and fits against the outer wall of the battery. The flat portion 211 is configured to contact and connect with the elastic contact portion 332 of the consumable battery assembly 3, forming a closed consumable battery circuit. The flat portion 211 is located near the proximal end of the loading member 1 and bends toward the battery, forming the bent portion 212. The bent portion 211 connects to the cathode or anode of the battery near the proximal end of the loading member 1.

[0074] In this embodiment, the length of the planar portion 211 of the metal connecting piece 21 is substantially equal to the length of the battery 20 .

[0075] The flat portion 211 connects to the consumable battery assembly 3, ensuring a smooth circuit and reliable operation. The curved portion 212 provides an effective connection to the battery electrodes. This simple, stable connection facilitates installation and maintenance. The overall design enables the metal connector 21 to establish a stable and efficient electrical connection between the battery and the consumable battery assembly, ensuring the proper operation and performance of the entire consumable battery compartment assembly.

[0076] Further, such as Figure 3 As shown, the insertion rod member 4 includes 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 is stopped at the end of the battery pack 2 .

[0077] The mating arrangement of the insertion rod 41 and the loading member 1 ensures stable and accurate insertion, allowing the rod 41 to be smoothly and securely inserted into the loading member 1, preventing any shaking or dislocation during use, thereby ensuring the reliability of the entire structural connection. The abutment of the fixing plate 40 against the end of the battery pack 2 intuitively indicates to the operator that the battery pack is properly installed, helping to improve installation efficiency and accuracy and reducing failures and safety hazards caused by improper installation.

[0078] Specifically, the fixing plate portion 40 has an L-shaped cross-section and includes a fixing plate body 401 and a connecting plate 402 extending perpendicularly from the fixing plate body 401 and away from the plug-in portion. The connecting plate 402 includes mounting holes for external connections. For example, when the self-consumable battery compartment assembly is mounted on a handle, the mounting holes in the connecting plate 402 provide a secure connection to the handle. Furthermore, the provision of the connecting plate 402 facilitates the operator's gripping of the connecting plate 402 to insert the inserting rod 4 into the hollow receiving cavity 10 of the loading member 1.

[0079] Specifically, strip-shaped protrusions 411 are provided on both the upper and lower sides of the inserting rod portion 41 for positioning.

[0080] Correspondingly, a positioning groove 13 is formed on the carrier 1, and the strip-shaped protrusion 411 of the insertion rod portion 41 is inserted into the positioning groove 13 of the carrier 1 to achieve the positioning 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 carrier 1 to ensure the position accuracy of the insertion rod 4 during insertion, avoiding poor contact or functional failure caused by installation deviation.

[0081] In addition, if Figure 4 As shown, the battery pack 2 can also be covered with a battery pack housing 23. Both ends of the battery pack housing 23 are provided with barb structures 24 for external connection. For example, when the self-consumable battery compartment assembly is installed on a handle, the barb structures 24 achieve a fixed connection with the handle. Covering the battery pack 2 with the battery pack housing 23 protects the battery pack 2 from external factors and damage. The barb structures 24 at both ends ensure the safe and stable installation of the battery pack 2.

[0082] Further, such as Figure 3 As shown, the self-consumable battery compartment assembly also includes a power supply connection part 5.

[0083] The power supply connection portion 5 is provided 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 portion 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 portion 5 is not limited in the present invention and can be designed by those skilled in the art based on actual conditions, as long as it can achieve communication with the battery pack 2 and thus realize external power supply.

[0084] When the battery is fully charged, the self-consumable battery compartment assembly with the power supply connection portion 5 can be inserted into the corresponding device, which not only provides power support for external devices or systems, but also meets the self-consumable power demand. When the self-consumable battery compartment assembly is removed, it can still discharge until the battery is exhausted.

[0085] The present invention further provides a medical device based on the above-mentioned self-consumable battery compartment assembly. Figure 1 As shown, it includes a handle portion 7, a functional portion 6 mounted at one end of the handle portion 7, and the aforementioned self-consumable battery compartment assembly mounted at the other end of the handle portion 7. The self-consumable battery compartment assembly is electrically connected to the functional portion 6 to provide power to it. Before use, the self-consumable battery compartment assembly is assembled to the other end of the handle portion and fixedly connected to the handle via 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 as shown in FIG. Figure 5 shown.

[0086] Specifically, for example, handheld active medical devices are usually equipped with disposable batteries, which are placed at the proximal end of the handle, and the distal end serves as the function implementation end. In this embodiment, for a disposable shock wave balloon, the electrode built into the distal end of the balloon serves as a shock wave generator to implement the corresponding function. The above-mentioned consumable battery compartment assembly is configured at the proximal end of the handle, and a pulse generator is provided on the handle portion. The consumable battery compartment assembly is electrically connected to the pulse generator, and the pulse generator is connected to the shock wave generator (i.e., the balloon) via a cable. Normally, the pulse generator will boost the voltage provided by the battery pack 2 in the consumable battery compartment assembly once or twice to reach 2 to 4KV, providing power for the handheld active medical device. This medical device includes all the technical solutions of the above-mentioned consumable battery compartment assembly, and at least has all the advantages of the consumable battery compartment assembly, which will not be repeated here.

[0087] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
