[0052] The endoscope handle is an important component of the endoscope. One end of the endoscope handle is connected to the endoscope body, and the other end is connected to the endoscope chassis. The function of the endoscope handle is to transmit the video signal obtained by the endoscope system to the endoscope chassis for further processing after preliminary processing, and to change the transmission method of the illumination light source.

[0053] Therefore, the endoscope handle should meet the corresponding electromagnetic compatibility test, among which the battery compatibility test is a process used to evaluate the performance of the device in an electromagnetic environment, in which the device may be interfered by other devices or external electromagnetic fields.

[0054] However, the current endoscope handle has the problem of poor electromagnetic compatibility due to its own structure.

[0055] In view of this, the present application provides an endoscope handle, which is additionally provided with an electromagnetic shielding component. Specifically, the electromagnetic shielding component includes a connecting portion and a shielding portion, both of which are used for the handle assembly, wherein the shielding portion is used to connect the device assembly and the handle barrel, and the connecting portion, and the connecting portion is connected to the device assembly. The device assembly is separated from the handle barrel by the shielding portion to avoid direct contact between the device assembly and the handle barrel, thereby improving the conductive isolation performance between the endoscope body and the handle barrel, and the conductive isolation performance between the device assembly and the handle barrel, and ultimately greatly improving the electromagnetic compatibility of the endoscope handle.

[0056] Please refer to Figures 1 to 4 In a first aspect, an embodiment of the present application provides an endoscope handle 100 , comprising a handle assembly 10 and an electromagnetic shielding assembly 20 .

[0057] The handle assembly 10 includes a handle barrel 11 and a device assembly 12 disposed in the handle barrel 11. The device assembly 12 has a proximal end 10a and a distal end 10b opposite to the proximal end 10a. The distal end 10b is used to connect with the endoscope body 400.

[0058] The electromagnetic shielding assembly 20 includes a connecting portion 21 and a shielding portion 22 which are sequentially arranged along the direction from the distal end 10b to the proximal end 10a. The shielding portion 22 is sleeved on the distal end 10b and connected to the handle barrel 11. The connecting portion 21 is covered on the end of the distal end 10b, and the endoscope body 400 is sequentially passed through the connecting portion 21 and the shielding portion 22.

[0059] It can be understood that the handle assembly 10 is used for medical personnel to hold and manipulate. Specifically, the handle barrel 11 is the shell part of the handle assembly 10, which fixes and supports the electromagnetic shielding assembly 20 inside it, and is also convenient for the operator's hand to hold it.

[0060] The device assembly 12 is the control part of the handle assembly 10, which is used to realize the input and output of corresponding control signals, similar to a control unit. The proximal end 10a of the device assembly 12 is the end close to the operator, and the distal end 10b is the end away from the operator.

[0061] The electromagnetic shielding assembly 20 is used to achieve electromagnetic isolation to improve the conductive isolation performance between the endoscope body 400 and the handle barrel 11. The connecting portion 21 can be made of metal or metal, and the shielding portion 22 is made of insulating material. The connection between the connecting portion 21 and the shielding portion 22 includes but is not limited to threaded connection, plug-in connection, and clamping connection.

[0062] Specifically, the shielding portion 22 is used to be sleeved on the distal end 10b of the device assembly 12 and connected to the handle barrel 11. For example, the outer wall of the shielding portion 22 is plugged into the inner wall of the handle barrel 11, or the shielding portion 22 is also sleeved on the outer wall of the handle barrel 11. The connecting portion 21 is covered on the distal end 10b of the device assembly 12. Finally, the endoscope body 400 (optical fiber) is sequentially passed through the connecting portion 21 and the shielding portion 22.

[0063] The endoscope handle 100 provided by the utility model is additionally provided with an electromagnetic shielding component 20. Specifically, the electromagnetic shielding component 20 includes a connecting portion 21 and a shielding portion 22, and the shielding portion 22 is used to separate the device component 12 from the handle barrel 11 to avoid direct contact between the device component 12 and the handle barrel 11, thereby improving the conductive isolation performance between the endoscope body 400 and the handle barrel 11, and the conductive isolation performance between the device component 12 and the handle barrel 11, and finally greatly improving the electromagnetic compatibility of the endoscope handle 100.

[0064] Please refer to Figures 1 to 4 , Figure 6 In some embodiments, the device assembly 12 includes a core shaft 121 and a mirror body joint 122 with electrical insulation. The core shaft 121 includes a supporting portion 1211 and a bearing portion 1212 connected to the supporting portion 1211. The mirror body joint 122 is arranged on a side of the supporting portion 1211 away from the bearing portion 1212. The bearing portion 1212 extends and is placed inside the handle barrel 11. The shielding portion 22 is sleeved on the mirror body joint 122 and is arranged in the handle barrel 11. The connecting portion 21 covers the mirror body joint 122.

[0065] It can be understood that the core shaft 121 is used as a carrier to support related components, and the mirror body connector 122 is used to connect with the endoscope mirror body 400. Specifically, the plane where the support portion 1211 is located is perpendicular to the plane where the bearing portion 1212 is located, that is, the support portion 1211 is connected to the mirror body connector 122 for installation of the mirror body connector 122, and the bearing portion 1212 is used for installation of corresponding components.

[0066] Furthermore, the mirror body connector 122 is connected to the endoscope mirror body 400, so the mirror body connector 122 has electrical insulation and is made of a corresponding electrically insulating material. At the same time, the mirror body connector 122 is connected to the handle barrel 11 by the shielding part 22, and the connecting part 21 is covered on the mirror body connector 122 to limit the endoscope mirror body 400.

[0067] In this way, the endoscope body connector 122 can be used to further electromagnetically isolate the endoscope body and the handle cylinder 11 , thereby improving the electromagnetic compatibility of the endoscope handle 100 .

[0069] It can be understood that the electromagnetic shielding assembly 20 is cone-shaped as a whole. Specifically, the connecting portion 21 is cone-shaped, and the transition section 221 of the shielding portion 22 also has a certain taper, so that the connecting portion 21 and the handle cylinder 11 have a smooth transition, and the shielding main body section 222 is connected to the handle cylinder 11 in a sleeve manner to meet corresponding installation requirements.

[0070] Here, the shielding main body section 222 and the handle cylinder body 11 may be interference fit, that is, the shielding main body section 222 is inserted into the handle cylinder body 11 , or the shielding main body section 222 is sleeved outside the handle cylinder body 11 .

[0071] Optionally, a corresponding annular groove structure is provided on the shielding main body section 222 so that when the shielding main body section 222 is plugged into the handle cylinder body 11 , the outer wall of the transition section 221 can also smoothly transition to the outer wall of the handle cylinder body 11 .

[0074] It can be understood that the first component 1221 of the scope connector 122 is used to connect with the support portion 1211 and to be sealed with the inner wall of the handle barrel 11. Here, the appearance structure of the first component 1221 is similar to the boss step structure. Specifically, the first sub-portion 12211 of the first component 1221 is connected to the connecting portion 21, and the second sub-portion 12212 is connected to the shielding portion 22 and to be sealed with the inner wall of the handle barrel 11. At the same time, the endoscope scope 400 is penetrated by the first component 1221, the second component 1222 and the third component 1223 to meet the fixation of the endoscope scope 400.

[0075] Optionally, an annular groove structure may be provided on the outer wall of the second sub-portion 12212, and a sealing ring may be provided in the annular groove structure to fix the sealing ring, and the sealing ring abuts against the inner wall of the handle cylinder 11 to achieve a sealed connection.

[0077] It can be understood that the buffer guide 13 is a metal part with a certain elasticity, so that when the circuit is turned on in the internal structural parts of the handle cylinder 11, the current can be introduced into the handle cylinder 11 to reduce current injuries. At the same time, its buffering characteristics can also be used to meet the squeezing of the handle cylinder 11 by the core shaft 121 during the installation process, so as to reduce the damage caused by squeezing of the internal structural parts.

[0078] Optionally, the buffer guide 13 can be a spring, and one end of the spring is large and the other end is small, presenting a cone shape as a whole.
