Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a medical power handle and surgical device with graphene heat dissipation. Background Technology
[0002] During operation, medical power handles (such as milling handles, grinding handles, etc.) generate heat from the moving parts (such as micro motors, gear sets) and electrical components (such as circuit boards) inside the handle.
[0003] Current power handles typically employ either air cooling or water cooling for heat dissipation. Water cooling, however, is more complex, costly, and inconvenient to operate. Air cooling, on the other hand, is more widely used. It involves installing cooling fan blades inside the handle, using vents and the fan blades to create air convection, thus achieving heat dissipation.
[0004] However, the heat dissipation efficiency of existing medical power handpieces is still relatively limited, and local overheating is likely to occur during long-term operation. Utility Model Content
[0005] The main purpose of this invention is to propose a graphene-based heat dissipation medical power handle and surgical device, which aims to reduce local overheating of the medical power handle.
[0006] To achieve the above objectives, the present invention proposes a medical power handle with graphene heat dissipation, comprising:
[0007] The casing has a receiving cavity;
[0008] A power output component is disposed inside the receiving cavity, and the power output component includes a micro motor;
[0009] And a graphene heat dissipation layer, disposed between the inner wall of the receiving cavity and the outer wall of the power output component, and at least partially close to the outer wall of the power output component.
[0010] In one embodiment, the graphene heat dissipation layer is a heat dissipation fin or heat dissipation film that is separately disposed from the housing.
[0011] In one embodiment, the heat sink or the heat dissipation film is made of graphene.
[0012] In one embodiment, the graphene heat dissipation layer extends from one end of the housing to the other end of the housing.
[0013] In one embodiment, the graphene heat dissipation layer is arranged circumferentially along the receiving cavity.
[0014] In one embodiment, the heat sink or the heat dissipation film is cylindrical.
[0015] In one embodiment, the thickness of the graphene heat dissipation layer is less than or equal to 1 mm.
[0016] In one embodiment, the graphene heat dissipation layer is bonded and fixed to the inner wall of the housing.
[0017] In one embodiment, the housing is provided with a vent that connects the receiving cavity to the external environment, and the graphene heat dissipation layer is provided with a clearance opening corresponding to the vent.
[0018] In one embodiment, the medical power handle further includes an impeller assembly rotatably disposed within the receiving cavity; and / or,
[0019] The ventilation opening includes an air inlet and an air outlet that are connected to each other, and an air duct is formed between the air inlet and the air outlet that passes through the power output component. The air inlet and the air outlet are located at both ends of the housing.
[0020] This utility model also proposes a surgical device, comprising:
[0021] The aforementioned medical powered handpiece with graphene heat dissipation; and
[0022] The cutting tool is driven and connected to the power output component.
[0023] The graphene-cooled medical power handle of this invention includes a housing, a power output component, and a graphene heat dissipation layer. The micromotor of the power output component provides power output. The graphene heat dissipation layer is disposed on the inner wall of the housing cavity, close to the power output component. This design is simple and easy to arrange. When the power output component operates, the heat generated is first transferred to the graphene heat dissipation layer. The graphene heat dissipation layer has high thermal conductivity and specific surface area (surface area per unit mass), enabling rapid heat dispersion and transfer to the housing. This reduces the heat accumulation around the power output component, lowers the operating temperature of the micromotor, improves the heat dissipation effect of the micromotor, thus preventing localized overheating around the power output component, improving the operational stability of the power output component, and extending the service life of the medical power handle.

[0039] This invention proposes a medical power handle with graphene heat dissipation.
[0040] Please see Figures 1 to 2 , Figure 1 A partial cross-sectional view of an embodiment of the graphene-cooled medical power handle provided by this utility model. Figure 2 for Figure 1 A magnified view of a portion of point A in the middle.
[0041] In one embodiment of this utility model, the graphene heat dissipation medical power handle includes:
[0042] The housing 100 has a receiving cavity 101;
[0043] The power output assembly 200 is disposed inside the receiving cavity 101, and the power output assembly 200 includes a micro motor 210; and
[0044] The graphene heat dissipation layer 300 is disposed between the inner wall of the receiving cavity 101 and the outer wall of the power output component 200, and is at least partially close to the outer wall of the power output component 200.
[0045] The graphene-cooled medical power handle of this invention includes a housing 100, a power output component 200, and a graphene heat dissipation layer 300. The micromotor 210 of the power output component 200 provides power output. The graphene heat dissipation layer 300 is disposed on the inner wall of the receiving cavity 101 of the housing 100 and close to the power output component 200. This design is simple and easy to arrange. When the power output component 200 operates, the heat generated is first transferred to the graphene heat dissipation layer 300. The graphene heat dissipation layer 300 has high thermal conductivity and specific surface area (surface area per unit mass), enabling rapid heat dispersion and transfer to the housing 100. This reduces the heat accumulation around the power output component 200, lowers the overall operating temperature of the power output component 200, improves the heat dissipation effect of the micromotor 210, thereby preventing localized overheating around the power output component 200, improving the operational stability of the power output component 200, and extending the service life of the medical power handle.
[0046] The power output component 200 comprises the moving parts and related electrical components within the medical power handle, such as a micro motor 210, bearing 220, gears, and circuit boards. The graphene heat dissipation layer 300 can be separately mounted from the housing 100 and then fixed using adhesives, welding, or screws; alternatively, it can be integrally formed with the housing 100 as a coating. The graphene heat dissipation layer 300 is at least partially adjacent to the outer wall of the power output component 200, meaning it can cover the entire inner wall of the housing 100, or it can be positioned only around the power output component 200.
[0047] In one embodiment, the graphene heat dissipation layer 300 is a heat dissipation fin or heat dissipation film that is separately disposed from the housing 100.
[0048] In the embodiments of this utility model, the graphene heat dissipation layer 300 is a heat dissipation fin or a heat dissipation film. Both the heat dissipation film and the heat dissipation fin are lightweight and have little impact on the weight of the medical power handle. Secondly, the separately configured heat dissipation fin or heat dissipation film can be made of different materials and sizes according to different usage environments and needs to adapt to different heat dissipation requirements. In addition, the heat dissipation fin or heat dissipation film, which is separately configured from the housing 100, can be replaced individually when it ages and is damaged, without having to replace the entire housing 100, thus reducing the maintenance cost of the medical power handle.
[0049] In the embodiments of this utility model, the heat sink or heat dissipation film is made of graphene. Graphene has a high thermal conductivity, which can more quickly conduct and disperse the heat generated by the power output component 200, thereby improving the heat dissipation efficiency. Furthermore, the manufacturing process of graphene film or graphene sheet is mature and readily available.
[0050] In one embodiment, the graphene heat dissipation layer 300 extends from one end of the housing 100 to the other end of the housing 100.
[0051] In an embodiment of this utility model, the graphene heat dissipation layer 300 extends from one end of the housing 100 to the other end, covering the entire inner wall of the receiving cavity 101. This allows local heat around the power output component 200 to be transferred to the entire interior of the housing 100 through the graphene heat dissipation layer 300, avoiding local overheating and maximizing the heat dissipation area within the receiving cavity 101, thereby improving the overall heat dissipation efficiency of the medical power handle.
[0052] In one embodiment, the graphene heat dissipation layer 300 is arranged circumferentially along the receiving cavity 101; and / or, the heat dissipation fins or heat dissipation film are cylindrical.
[0053] Combination Figure 1 and Figure 3 In this embodiment of the invention, the graphene heat dissipation layer 300 is arranged circumferentially along the receiving cavity 101 to increase the heat dissipation area and dissipate heat from the power output component 200 in the circumferential direction. The heat generated by the power output component 200 is easily transferred to the surrounding graphene heat dissipation layer 300, further improving the heat dissipation efficiency. The specific shape of the graphene heat dissipation layer 300 corresponds to the receiving cavity 101 of the housing 100. Specifically, in this embodiment, the receiving cavity 101 is cylindrical, and the graphene heat dissipation layer 300 on the inner wall of the receiving cavity 101 is cylindrical.
[0054] In one embodiment, the thickness of the graphene heat dissipation layer 300 is less than or equal to 1 mm.
[0055] In the embodiments of this utility model, the thickness of the graphene heat dissipation layer 300 is no more than 1mm, and can be 1mm, 0.5mm, 0.1mm, etc. The graphene heat dissipation layer 300 is relatively thin and light, and has little impact on the overall weight of the medical power handle, making it convenient for users to hold. In addition, the graphene heat dissipation layer 300 occupies a small amount of internal space in the receiving cavity 101, and is unlikely to affect the arrangement of other components in the receiving cavity 101.
[0056] In one embodiment, the graphene heat dissipation layer 300 is bonded and fixed to the inner wall of the housing 100.
[0057] In the embodiments of this utility model, the graphene heat dissipation layer 300 is bonded and fixed to the inner wall of the receiving cavity 101 by adhesive. The fixation is reliable and not easy to fall off. Furthermore, there is no gap or a very small gap between the graphene heat dissipation layer 300 and the inner wall of the receiving cavity 101, which makes it easier to transfer heat to the housing 100 and realize heat dissipation of the power output component 200.
[0058] In one embodiment, the housing 100 is provided with a vent 110 that connects the receiving cavity 101 to the external environment, and the graphene heat dissipation layer 300 is provided with a clearance corresponding to the vent 110.
[0059] Reference Figure 4 In this embodiment of the invention, the housing 100 is provided with a vent 110, through which outside air enters and exits the receiving cavity 101, carrying away heat from the cavity and further improving the heat dissipation efficiency of the medical power handle. The graphene heat dissipation layer 300 is provided with an avoidance opening corresponding to the vent 110. The shape and size of the ventilation hole correspond to the vent 110 to avoid obstructing the vent 110 and ensure smooth airflow through it.
[0060] In one embodiment, the medical power handle further includes an impeller assembly 400, which is rotatably disposed inside the receiving cavity 101; and / or,
[0061] The vent 110 includes an air inlet and an air outlet that are connected to each other. An air duct is formed between the air inlet and the air outlet, which passes through the power output component 200. The air inlet and the air outlet are located at both ends of the housing 100.
[0062] Combination Figure 1 and Figure 4 In this embodiment of the invention, an impeller assembly 400 is further provided inside the receiving cavity 101. The impeller assembly 400 can actively drive airflow, enhance air flow, and allow air inside the receiving cavity 101 to be discharged through the vent 110, thereby further improving the heat dissipation efficiency of the medical power handpiece. On the other hand, the air-cooling function of the impeller assembly 400 combined with the graphene heat dissipation layer 300 can maintain good heat dissipation even when using a relatively thin graphene heat dissipation layer 300, and reduce the heat transferred through the graphene heat dissipation layer 300, thus extending the service life of the graphene heat dissipation layer 300.
[0063] Combination Figure 1 and Figure 4 In this embodiment of the invention, the vent 110 includes an air inlet and an air outlet, which are respectively located at both ends of the housing 100. Air enters the interior of the receiving cavity 101 from the air inlet at one end of the housing 100, undergoes heat exchange with the power output component 200 to form hot air, and is then discharged from the air outlet at the other end of the housing 100, forming a relatively long airflow path. This ensures good heat dissipation for the power output component 200 and helps reduce heat dissipation dead zones within the receiving cavity 101. Specifically, multiple air inlets and multiple air outlets are spaced apart along the circumference of the housing 100, increasing the airflow and ensuring unobstructed airflow.
[0064] This utility model also proposes a surgical device, comprising:
[0065] The aforementioned medical powered handpiece with graphene heat dissipation; and
[0066] The cutting tool is driven and connected to the power output assembly 200.
[0067] The specific structure of the graphene-cooled medical powered handle is as described in the above embodiments. Since this surgical device adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here. This graphene-cooled medical powered handle can be applied to various types of surgical equipment, such as medical milling cutters, medical scalpels, and medical ultrasonic scalpels.
