[0041] The present invention provides a handle structure 100, and the handle structure 100 is applicable to an endoscope. The endoscope generally further includes an insertion portion 200, and the insertion portion 200 is used to be inserted into a patient's body to detect and treat the affected area. The handle structure 100 is used for a medical staff to hold, so as to better perform detection and treatment.

[0042] Please refer to Figures 1 to 5 , the handle structure 100 includes a handle 1, a plug-in portion 2, and a first connecting member 3; the handle 1 includes an operation portion 11 and a connecting portion 12, the operation portion 11 is used to accommodate the traction portion 300 of the endoscope, the connecting portion 12 has opposite first and second ends 121 and 122 in a first direction F1, and the first end 121 is connected to the operation portion 11; the plug-in portion 2 is disposed at the second end 122 and is used to connect the insertion portion 200 of the endoscope; the first connecting member 3 is disposed inside the handle 1 and connects the operation portion 11 and the connecting portion 12, a first mounting portion 4 for mounting the light source of the endoscope is provided on the first connecting member 3, and the first connecting member 3 forms a heat dissipation structure 5 at least at a position corresponding to the first mounting portion 4.

[0043] The handle structure 100 provided by the present invention includes a handle 1, a plug-in portion 2, and a first connecting member 3; in the first direction F1, an operating portion 11, a connecting portion 12, and the plug-in portion 2 are connected in sequence. The operating portion 11 is used to accommodate the traction portion 300 of the endoscope, and the plug-in portion 2 is used to connect the insertion portion 200 of the endoscope; a first connecting member 3 is arranged inside the handle 1 to connect the operating portion 11 and the connecting portion 12; in order to make the internal structure arrangement of the handle 1 more reasonable, a first mounting portion 4 is arranged on the first connecting member 3 for mounting the light source of the endoscope; and during the use of the endoscope, the light source generates heat, causing the corresponding area of the handle 1 to heat up and affecting the user's operation; a heat dissipation structure 5 is formed at a position corresponding to the first mounting portion 4 on the first connecting member 3 to dissipate heat from the light source mounted thereon, avoiding the accumulation of heat generated by the light source, thereby reducing the temperature rise of the corresponding position of the handle 1, and further eliminating the influence of the light source heating on the user and improving the user experience.

[0044] In an embodiment, the first connecting member 3 is detachably connected to the operating portion 11 and the connecting portion 12; in this way, by disassembling and assembling the first connecting member 3, the disassembly or assembly of the operating portion 11 and the connecting portion 12 can be realized; furthermore, the internal parts of the handle 1 can be repaired and replaced; the structure is simple and the operation is convenient.

[0045] The present application does not specifically limit the formation method of the heat dissipation structure 5. In an embodiment, a heat dissipation element is arranged on the first connecting member 3, so as to form a heat dissipation structure 5 with heat dissipation function on the first connecting member 3; in another embodiment, by improving the material or structure of a local position of the first connecting member 3, the heat dissipation structure 5 is formed at the local position thereof.

[0046] It can be known that usually when the user operates the handle 1, the connection part of the operating portion 11 and the connecting portion 12 will be held, that is to say, the connection part of the operating portion 11 and the connecting portion 12 forms the holding area of the handle 1. And, based on the internal structure of the handle 1, the light source of the endoscope is mounted on the first connecting member 3, and the light source of the endoscope is located inside the connecting portion 12 and is arranged close to the operating portion 11.

[0047] In an embodiment, please refer to Figures 6 to 8 , the first connecting member 3 includes a first plate member 31 and a second plate member 32. The first plate member 31 and the second plate member 32 are arranged in parallel and in the same direction in the first direction F1. Two adjacent ends of the first plate member 31 and the second plate member 32 are connected. The first plate member 31 is connected to the operating portion 11, and the second plate member 32 is connected to the connecting portion 12; in this way, the connection between the operating portion 11 and the connecting portion 12 is realized through the first plate member 31 and the second plate member 32.

[0048] And based on the internal structure of the handle 1 described above, since the light source of the endoscope is located within the connection portion 12 and is disposed close to the operation portion 11, the light source of the endoscope is mounted on the second plate member 32. That is to say, the second plate member 32 can serve both as a connecting member between the operation portion 11 and the connection portion 12 and as a mounting member for the endoscope light source. In this way, the internal structure of the handle 1 can be simplified.

[0049] Meanwhile, the light source of the endoscope is mounted on the second plate member 32. To prevent the heat generated by the endoscope light source from being transferred to the handle 1 and causing the temperature of the gripping area of the handle 1 to rise, the second plate member 32 is configured as a heat dissipation plate to form a heat dissipation structure 5 for dissipating heat from the light source, thereby reducing the temperature rise of the gripping area of the handle 1 and further eliminating the influence of the light source heating on the user, improving the user experience.

[0050] That is to say, the first connecting member 3 includes a first plate member 31 and a second plate member 32. The first plate member 31 serves only as a connecting member to connect with the operation portion 11; the second plate member 32 can serve both as a connecting member connecting the connection portion 12 and as a mounting member for mounting the endoscope light source, and can also serve as a heat dissipation member for the endoscope light source. In this way, the first connecting member 3 provided in a split manner can not only satisfy the connection between the operation portion 11 and the connection portion 12 and the mounting of the endoscope light source, but also satisfy the heat dissipation of the light source.

[0051] This application does not specifically limit the connection method between the first plate member 31 and the second plate member 32. The two adjacent ends between the first plate member 31 and the second plate member 32 can be fixedly connected by a threaded connection structure; the two adjacent ends between the first plate member 31 and the second plate member 32 can also be fixedly connected by welding.

[0052] Moreover, the first plate member 31 and the operation portion 11 can be fixedly connected or detachably connected; the second plate member 32 and the connection portion 12 can be fixedly connected or detachably connected; no specific limitation is made here.

[0053] To further improve the heat dissipation effect of the second plate member 32; in an embodiment, heat dissipation holes 6 are formed on the second plate member 32; by providing the heat dissipation holes 6, the contact area between the second plate member 32 and the air is increased, thereby further improving the heat dissipation effect of the second plate member 32.

[0054] As described above, the first connecting member 3 is provided in a split form, and the first plate member 31 is only used as a connecting member to be detachably connected to the operating portion 11; the second plate member 32 can be used both as a connecting member connecting the portion 12 and an installation member for installing an endoscope light source, and can also be used as a heat dissipation member for the endoscope light source.

[0055] In the present application, the first plate member 31 is provided as a stainless steel sheet metal part; since the first plate member 31 is detachably connected to the operating portion 11 as a connecting member, the first plate member 31 can be made of a material with relatively high strength, so as to improve the connection strength of the first plate member 31.

[0056] In the present application, the second plate member 32 is provided as one of an aluminum plate, a copper plate, and an aluminum alloy plate; since the second plate member 32 can be used both as a connecting member connecting the connection and an installation member for installing an endoscope light source, and can also be used as a heat dissipation member for the endoscope light source, the second plate member 32 can be made of a material with good heat conduction performance, so that the second plate member 32 can quickly absorb the heat of the light source and quickly dissipate heat, thereby improving the heat dissipation effect of the second plate member 32.

[0057] It should be noted that the above two technical features can be set alternatively or simultaneously; specifically, the above two technical features are set simultaneously, that is, the connection strength is improved through the first plate member 31, and the heat dissipation effect is improved through the second plate member 32.

[0058] In an embodiment, please refer to Figure 2 and Figure 3 , both the operating portion 11 and the connecting portion 12 are provided in a hollow shape and are internally communicated; the end of the first plate member 31 away from the second plate member 32 is detachably connected to the operating portion 11, the second plate member 32 extends along the first direction F1 and passes through the connecting portion 12, and the end of the second plate member 32 away from the first plate member 31 is detachably connected to the second end 122.

[0059] That is to say, in this embodiment, the first plate member 31 is detachably connected to the operating portion 11 as a connecting member; the second plate member 32 extends along the first direction F1 and passes through the connecting portion 12, and the end of the second plate member 32 away from the first plate member 31 is detachably connected to the second end 122; and the second plate member 32 is used as a heat dissipation plate. After the second plate member 32 absorbs the heat generated by the endoscope light source, it will transfer the heat toward the plugging portion 2 side, so as to avoid heat accumulation in the gripping area of the handle 1, thereby eliminating the influence of the light source heating on the user and improving the user experience.

[0060] The operation part 11 and the connection part 12 are both hollow, and the operation part 11 is in plug-in fit with the connection part 12; in order to facilitate the connection between the operation part 11 and the first plate member 31, in an embodiment, please refer to Figures 2 to 5 , a connection protrusion 111 protrudes from the inner wall of the operation part 11; the end of the first plate member 31 away from the second plate member 32 is bent to form a connection convex edge 33, and the connection convex edge 33 is connected to the connection protrusion 111 through a detachable connection structure.

[0061] This application does not specifically limit the connection method between the connection convex edge 33 and the connection protrusion 111. The connection convex edge 33 and the connection protrusion 111 can be fixed by snap connection; the connection convex edge 33 and the connection protrusion 111 can also be fixed by a threaded connection structure.

[0062] Moreover, the handle 1 further includes a second connecting member 13 disposed at the second end 122, and the second connecting member 13 connects the plugging part 2; that is, the connection part 12 and the plugging part 2 are connected through the second connecting member 13; in order to facilitate the detachable connection between the second plate member 32 and the connection part 12, the end of the second plate member 32 away from the first plate member 31 is detachably connected to the second connecting member 13.

[0063] This application does not specifically limit the connection method between the second plate member 32 and the second connecting member 13. The second plate member 32 and the second connecting member 13 can be fixed by snap connection; the second plate member 32 and the second connecting member 13 can also be fixed by a threaded connection structure.

[0064] As mentioned above, by locally providing heat dissipation for a part of the first connecting member 3, the heat generated by the endoscope light source installed thereon is dissipated; however, during the actual operation process, part of the heat still transfers to the handle 1, thus affecting the user operation. Thus, in order to further eliminate the influence of the light source heating on the user, in an embodiment, please refer to Figure 9 , the handle structure 100 further includes a heat insulation part 7, the heat insulation part 7 is disposed on the handle 1, and the heat insulation part 7 is arranged corresponding to the position of the light source to block the heat generated by the light source.

[0065] Moreover, based on the internal structure of the handle 1, the light source of the endoscope is installed on the first connecting member 3, and the light source of the endoscope is within the connecting portion 12 and is disposed close to the operating portion 11.
