Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a shell, an operating handle and an endoscope. BACKGROUND

[0002] An endoscope is a commonly used medical device, which is an inspection instrument capable of directly entering a natural cavity of a human body, and can provide sufficient diagnostic information for a doctor to treat a disease. In actual operation, the handle shell is prone to static electricity due to friction and / or contact with static electricity with hands and / or clothes, and the relative deformation of the components of the shell during operation can also cause friction and generate static electricity on the shell. These static electricity accumulated on the handle shell can enter the inside of the shell through the gap between the shells and other positions, affecting the circuit board or other electronic components inside the shell, affecting signal processing or damaging the circuit system, and thus causing the endoscope to be unable to normally perform endoscopic operation or other control functions. SUMMARY

[0003] In view of the shortcomings of the above related technologies, the present application provides a shell, an operating handle and an endoscope to solve the above technical problems.

[0004] The present application provides a shell for an endoscope, the shell having a receiving cavity inside, the receiving cavity being adapted to accommodate electronic components, the shell having a gap, the gap being in communication with the outside of the shell, the shell being provided with a conductive member extending along the direction of the gap between the gap, the conductive member at least partially shielding the gap and being used to guide the charge reaching the gap from the outside or the outer surface of the shell.

[0005] To achieve the above object and other related objects, the present application provides an operating handle, which comprises the aforementioned shell and electronic components, the electronic components being installed in the receiving cavity; Alternatively, the operating handle comprises the aforementioned shell, electronic components and a cable, the electronic components being installed in the receiving cavity, the cable being installed in the cable installation port of the shell, and the first clamping portion of the shell clamping the cable; Alternatively, the operating handle comprises the aforementioned shell, electronic components, a negative pressure connector and a cable, the cable being installed in the cable installation port of the shell, the negative pressure connector being installed in the instrument installation port of the shell, the electronic components being installed in the receiving cavity, the first clamping portion of the shell clamping the cable, and the second clamping portion of the shell clamping the negative pressure connector.

[0006] To achieve the above object and other related objects, the present application provides an endoscope comprising the aforementioned operating handle.

[0007] The technical scheme adopted by the present application can achieve the following beneficial effects: the shell can provide protection for the electronic components, avoid external dust and foreign matter from entering the accommodating cavity, and improve the protection capability. The shell has a gap, and the handle shell is easy to generate static electricity due to friction and / or contact with the hands and / or clothes. The static charge can enter the accommodating cavity from the gap. The conductive part can play a dredging role on the charge conducted to the gap from the outside or the outer surface of the shell. The conductive part can timely guide and shunt the charge accumulated in the gap, thereby preventing the charge from damaging the electronic components in the shell.

[0008] In addition, the conductive part of the present application is arranged between the gap, which can dredge the external charge at the gap. After the conductive part enters the interior of the shell, the conductive part can conduct along the inner wall to damage the electronic components, thereby further improving the protection capability. At the same time, because the conductive part is arranged between the gap, the conductive part does not occupy the space in the interior of the shell, which can optimize the internal layout of the shell, avoid the increase in the volume of the shell due to the need to arrange the conductive part, and reduce the volume of the endoscope, thereby facilitating the long-time holding and operation of the medical staff.

[0012] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0013] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0014] In the various embodiments of this application, "proximal end" and "far end" refer to the position of each component relative to the user in the usage environment. The end closer to the user is designated as the "proximal end", and the end farther from the user is designated as the "far end".

[0015] Static electricity accumulating on the handle housing may enter the housing through gaps or other locations, affecting the circuit boards or other electronic components inside the housing, impacting signal processing or damaging the circuit system, and consequently causing the endoscope to malfunction and fail to perform endoscopic operations or other control functions.

[0016] Existing solutions involve making the housing a single, integrated structure or sealing the gaps in the housing with adhesive. These methods reduce gaps and decrease the risk of electrical charge entering the housing. However, during subsequent repairs or upgrades, single-piece or adhesive-sealed housings are difficult to disassemble, leading to endoscope failure and unusable parts. Furthermore, designing and manufacturing a single-piece housing requires high precision, increasing manufacturing difficulty and cost. This also reduces endoscope assembly efficiency because sealing gaps with adhesive requires an additional adhesive sealing process, further increasing manufacturing costs.

[0017] This application provides a housing 110, please refer to... Figure 1 This is used for endoscope 1. Furthermore, the housing 110 can be the outer housing of the operating handle 100 of endoscope 1, providing protection for the components of endoscope 1 to improve its protective capabilities. In other cases, the housing 110 can be the inner housing 110 of the operating handle 100 of endoscope 1, i.e., a portion of the housing located inside the outer casing, or the housing 110 can be the housing of the insertion portion of endoscope 1, etc., without limitation. For ease of description, the following description uses the outer housing of the operating handle 100 as an example.

[0018] The material of the shell 110 can be polycarbonate (PC), nylon (PA), etc., and there are no restrictions on it.

[0019] Please see Figure 2 as well as Figure 3 The housing 110 has a receiving cavity 111, which is suitable for accommodating electronic components 120. The electronic components 120 include, but are not limited to, circuit boards and their components, camera buttons, etc. The housing 110 provides protection for the electronic components 120, preventing external dust and foreign objects from entering the receiving cavity 111, thus improving protection.

[0020] Please see Figure 3The housing 110 has a slit 112 that connects the receiving cavity 111 to the outside of the housing 110. The slit 112 can be a joint gap between multiple interconnected components, such as a seam between two components, or it can be a movement gap between multiple relatively moving components, such as the gap between the camera button and the wall on which it is mounted. The slit 112 connects the receiving cavity 111 to the outside of the housing 110 and also balances the pressure inside and outside the housing 110, while transferring internal heat to the outside. Furthermore, in the reusable endoscope 1, its operating handle 100 may require modification or repair; the slit 112 in the housing 110 allows the operator to disassemble the housing 110 along the slit 112 for easy disassembly.

[0021] Please see Figure 4 The housing 110 has conductive elements 113 extending along the direction of the gaps 112 within the gaps 112. The conductive elements 113 can be stainless steel or graphite, and the type of conductive element 113 is not limited. For example... Figure 3 As shown, the gap 112 refers to the gap area formed at the mating part of two or more components. The housing 110 has the gap 112. The handle housing 110 is prone to static electricity due to friction and / or contact with hands and / or clothing. Static charge may enter the receiving cavity 111 through the gap 112. The conductive element 113 at least partially blocks the gap 112. The conductive element 113 acts as an electrostatic shield, preventing electrostatic breakdown of the air and damage to the internal electronic components 120. Simultaneously, the conductive element 113 conducts charge reaching the gap 112 from the outside or outer surface of the housing 110. Preferably, the conductive element 113 can block all parts of the gap 112 to prevent charge from entering the receiving cavity 111 from the gap 112. The conductive element 113 can conduct charge from the outside or outer surface of the housing 110 to the gap 112. That is, the conductive element 113 can promptly guide and divert the charge accumulated at the gap 112, preventing excessive charge accumulation and high electrostatic voltage, thereby preventing charge breakdown or damage to the electronic components 120 inside the housing 110. In this application, electrostatic charge can be conducted or shielded solely by the conductive element 113, ensuring the safe use of the internal electronic components 120 without requiring increased manufacturing precision of the housing 110. This reduces the design and molding costs associated with manufacturing precision, achieving more effective anti-static performance with a lower-cost conductive element 113. This also helps control the cost of the endoscope 1, which is crucial for disposable endoscopes that require cost reduction and efficiency improvement.

[0022] Understandably, in one scenario, a charge could enter the receiving cavity 111 from somewhere in the gap 112. The conductive element 113 could absorb this charge and carry it away from the gap 112 to an area of ​​the housing 110 away from the electronic component 120, preventing the charge from interfering with or damaging the electronic component 120. In another scenario, the conductive element 113 could absorb the charge and disperse it throughout itself, reducing the degree of charge accumulation and mitigating the risk of damage to the electronic component 120. Of course, the conductive element 113 can exist in both modes simultaneously during normal operation to mitigate the risk of charge damage and improve protective capabilities.

[0023] In a more specific embodiment, the housing 110 may be assembled from at least two splicing components to form a receiving cavity 111. The number of splicing components can be two, three, or even more, and is not limited. A gap 112 is formed between the mating surfaces of the two splicing components. An operator can disassemble the housing 110 through the gap 112. A conductive element 113 may be disposed at the mating surface; the conductive element 113 can block and conduct electrical charges, preventing external static electricity from entering the receiving cavity 111.

[0024] For further details, please refer to Figure 2 At least two splicing components may include a first sub-shell 1141 and a second sub-shell 1142 spliced ​​together. The structures of the first sub-shell 1141 and the second sub-shell 1142 may be the same or different. For example, the first sub-shell 1141 and the second sub-shell 1142 may be the same and mirror image structure, or the first sub-shell 1141 and the second sub-shell 1142 may be two different structures distributed along the axis of the operating handle 100. The first sub-shell 1141 and the second sub-shell 1142 form a receiving cavity 111, and a gap 112 is formed between the mating surfaces of the first sub-shell 1141 and the second sub-shell 1142. A first groove 1171 is provided at the mating surface of the first sub-shell 1141, and a second groove 1172 is provided at the mating surface of the second sub-shell 1142. A conductive element 113 is disposed in the first groove 1171 and the second groove 1172. When static electricity is generated by friction between the mating surfaces of the first sub-shell 1141 and the second sub-shell 1142, or by friction between the hands or clothing of medical personnel, static charge may accumulate at the mating surfaces of the first sub-shell 1141 and the second sub-shell 1142. In this case, the conductive element 113 located in the first groove 1171 and the second groove 1172 can promptly absorb and dissipate the charge at the mating surfaces, preventing the accumulation of a large amount of charge. This allows for efficient charge dissipation in the early stages of charge accumulation, preventing voltage increases due to excessive charge buildup, effectively eliminating the possibility of electrostatic breakdown, and improving operational safety.

[0025] Furthermore, the number of conductive elements 113 can be at least two, and the at least two conductive elements 113 can be distributed in different splicing areas or multiple different splicing surfaces. The conductive elements 113 can protect against electric charge and prevent electric charge from damaging the electronic components 120.

[0026] In the embodiments of this application, please refer to Figure 4 The housing 110 is provided with a mounting position located within the receiving cavity 111, and the mounting position is used to fix and mount the electronic component 120. The mounting position can be a groove, hole, or other form formed by a component inside the housing 110, or the surface of the housing 110 forming the gap 112, etc., and is not limited thereto. The conductive element 113 extends from the part of the gap 112 closest to the mounting position. This ensures that the conductive element 113 acts as a shield at the position where electrostatic charge is most likely to approach the electronic component 120, so that the charge is conducted from the part of the gap 112 near the electronic component 120 to a place farther away from the mounting position, thereby more directly blocking the conduction path of charge from the gap 112 to the electronic component 120, effectively improving the protection capability of the electronic component 120 inside the housing 110.

[0027] In the embodiments of this application, please refer to Figure 3 as well as Figure 5 The conductive element 113 has an opening 1134. The groove walls of the first groove 1171 and / or the second groove 1172 are provided with limiting portions 1173. The limiting portions 1173 can be embedded in the opening 1134 and abut against the conductive element 113. For example, the conductive element 113 may include a first frame 1131, a second frame 1132, and a third frame 1133. The first frame 1131 and the second frame 1132 are disposed opposite to each other. One end of the third frame 1133 is connected to one end of the first frame 1131, and the other end is connected to one end of the second frame 1132. The opening 1134 is formed between the first frame 1131 and the second frame 1132 and is located at a position opposite to the third frame 1133. The first frame 1131 is embedded in the first groove 1171, and the second frame 1132 is embedded in the second groove 1172. The limiting part 1173 of the first groove 1171 and the limiting part 1173 of the second groove 1172 are both embedded in the opening 1134 so that the first sub-shell 1141 and the second sub-shell 1142 are connected to each other.

[0028] The gap 112 between the first sub-shell 1141 and the second sub-shell 1142 is formed between the limiting part 1173 of the first groove 1171 and the limiting part 1173 of the second groove 1172. Static charge will enter the opening 1134 through the gap 112. The conductive element 113 can completely block the charge and prevent the charge from being transferred from the gap 112 to the receiving cavity 111.

[0029] Furthermore, the first sub-shell 1141 and the second sub-shell 1142 deform and separate under the action of external force. During the separation of the first sub-shell 1141 and the second sub-shell 1142, the limiting portion 1173 of the first groove 1171 and the limiting portion 1173 of the first frame 1131 are pressed against each other, and the limiting portion 1173 of the second groove 1172 and the limiting portion 1173 of the first frame 1131 are also pressed against each other. The conductive element 113 is driven and undergoes a slight deformation. The deformed conductive element 113 generates a force to recover its deformation. This force can drive the first sub-shell 1141 and the second sub-shell 1142 to move towards each other, preventing the gap 112 between the first sub-shell 1141 and the second sub-shell 1142 from widening. In other words, the conductive element 113 can limit the maximum opening and closing range of the gap 112 between the first sub-shell 1141 and the second sub-shell 1142, reduce the risk of static electricity entering the receiving cavity 111, improve the stability of the shell 110, and provide a better user experience.

[0030] At the same time, the first sub-shell 1141 and the second sub-shell 1142 separate under the action of external force. The conductive element 113 will deform and generate elastic force. The elastic force resisting the deformation will drive the conductive element 113 to act on the surface of the first sub-shell 1141 and the second sub-shell 1142, so that the conductive element 113 and the first sub-shell 1141 and the second sub-shell 1142 are in closer contact, and the charge is prevented from moving from the groove wall surface of the first groove 1171 and / or the second groove 1172. That is, the conductive element 113 isolates the inside and outside of the shell 110, thereby improving the protection capability.

[0031] In another scenario, the first frame 1131 of the conductive element 113 is bent to form a first opening, which is mutually positioned and engaged with the limiting portion 1173 of the groove wall of the first groove 1171. Simultaneously, the second frame 1132 is bent to form a second opening, which is mutually positioned and engaged with the limiting portion 1173 of the groove wall of the second groove 1172; this will not be elaborated further here.

[0032] In the embodiments of this application, please refer to Figure 6 as well as Figure 7 The conductive element 113 is grounded, enabling it to conduct charge to a greater distance, preventing excessive charge from being difficult to dissipate in time. Simultaneously, because the conductive element 113 is grounded, its potential is low, allowing it to quickly absorb and dissipate charge, thus improving protective performance. For example, the housing 110 is equipped with a grounding harness, and the conductive element 113 is electrically connected to the grounding harness, allowing the charge absorbed by the conductive element 113 to be quickly conducted to a greater distance.

[0033] In one implementation, please refer to Figure 7The housing 110 has a cable mounting port 115. For example, the cable mounting port 115 can be an opening for mounting a cable 140. When the housing 110 includes a first sub-housing 1141 and a second sub-housing 1142, a portion of the wall of the cable mounting port 115 is formed in the first sub-housing 1141, and the remaining wall is formed in the second sub-housing 1142. While the first sub-housing 1141 and the second sub-housing 1142 are connected and form a receiving cavity 111, the cable mounting port 115 is formed between the first sub-housing 1141 and the second sub-housing 1142. The cable mounting port 115 is suitable for mounting a cable 140 connected to the electronic component 120. The cable 140 includes, but is not limited to, signal lines, power lines, etc. The cable 140 can transmit signals or power to the electronic component 120, etc., and is not limited thereto. Cable 140 has a ground wire 141. The ground wire 141 can be an existing wire harness on cable 140 suitable for electrical connection to the grounding terminal of electronic component 120, such as a wire harness connecting to the grounding terminal of a circuit board. Alternatively, the ground wire 141 can be a separate wire harness within cable 140 for separate connection to conductive component 113, without limitation. Conductive component 113 extends to cable mounting port 115 and is suitable for electrical connection to the ground wire 141 of cable 140. This arrangement not only enables grounding of conductive component 113 to quickly conduct charge to a greater distance, improving protection capability, but also integrates the ground wire 141 for grounding within cable 140, reducing the number of cables 140 and increasing the integration of cable 140.

[0034] Please see Figure 7 A mounting groove 1151 is provided on the wall forming the cable mounting port 115, and the conductive element 113 is also provided with a first clamping part 1135. The first clamping part 1135 includes a limiting sub-part 1136 and a connecting sub-part 1137. The limiting sub-part 1136 is adapted to radially clamp the cable 140 and is electrically connected to the ground wire 141 of the cable 140. The connecting sub-part 1137 is connected to the limiting sub-part 1136, and at least a portion of the connecting sub-part 1137 is embedded in the mounting groove 1151 to axially limit the cable 140. The limiting sub-part 1136 can radially clamp the cable 140 and form an electrical connection with the ground wire 141 of the cable 140, while the connecting sub-part 1137 is connected to the limiting sub-part 1136 and remains conductive. After at least a portion of the connecting sub-part 1137 is embedded in the mounting groove 1151, it achieves both axial positioning of the cable 140 and prevents charge from entering the receiving cavity 111 by blocking the gap 112 between the cable 140 and the housing 110 through the positioning sub-part 1136. Furthermore, with the first sub-housing 1141 and the second sub-housing 1142 clamping each other, the connecting sub-part 1137 can be fixed and constrained axially.

[0035] More specifically, please see Figure 8 as well as Figure 9The limiting sub-part 1136 can be a ring-shaped structure, adapted to clamp the sheath 142 of the cable 140. The sheath 142 is a component used to connect and protect the cable 140, effectively preventing the cable 140 from being broken. The limiting sub-part 1136 can surround the periphery of the sheath 142 to restrict the sheath 142 radially. When the sheath 142 is subjected to external force and shifts, the limiting sub-part 1136 and the connecting sub-part 1137 are moved accordingly. However, the portion of the connecting sub-part 1137 pulled out from the mounting groove 1151 can still block electrostatic charge and prevent electrostatic breakdown. The limiting sub-part 1136 cooperates with the limiting structure of the sheath 142 to axially limit the sheath 142 and the housing 110. Furthermore, when the limiting sub-part 1136 clamps the sheath 142 of the cable 140, it cooperates with the limiting structure on the sheath 142. The limiting sub-part 1136 effectively restricts the axial displacement between the sheath 142 of the cable 140 and the housing 110, ensuring the stability of the axial limiting. For example, as shown... Figure 8 As shown, the limiting structure can also be a connecting groove, which can be used to install the first clamping part 1135. The limiting part 1136 can abut against the groove wall of the connecting groove to further limit the axial displacement between the sheath 142 and the housing 110.

[0036] Furthermore, in the embodiments of this application, please refer to Figure 10 The conductive element 113 is further provided with a second clamping portion 1138. The housing 110 may also include an instrument mounting port 116, which is suitable for mounting a negative pressure connector 130. The second clamping portion 1138 is disposed at the instrument mounting port 116 and is suitable for radially clamping the negative pressure connector 130. The second clamping portion 1138 of the conductive element 113 is disposed at the instrument mounting port 116 of the housing 110 and can radially clamp the negative pressure connector 130 installed therein. This clamping method covers the gap 112 between the negative pressure connector 130 and the housing 110, further preventing charge from entering the receiving cavity 111. At the same time, this clamping method can also reduce the axial and radial sway of the cable 140, because the wall forming the instrument mounting port 116 can also be provided with a mounting groove, and the second clamping portion 1138 can mutually limit the movement of the negative pressure connector 130 along the axial direction. In addition, at least one splicing component surrounds the outer surface of the second clamping portion 1138 to restrict the radial movement of the second clamping portion 1138. Under this constraint, the second clamping portion 1138 is restricted in both the axial and radial directions of the cable 140, and the amplitude of sway of the connected cable 140 is reduced at least in its own axial and radial directions to reduce static electricity generation and maintain the closure quality of the gap 112.

[0037] Of course, in other cases, the instrument mounting port 116 can also be used to mount other components, such as insertion tubes, without any restrictions.

[0038] To achieve the above and other related objectives, this application provides an operating handle 100. Please refer to [link / reference]. Figure 1 This gives the operating handle 100 the beneficial effects of any of the aforementioned solutions, which will not be elaborated further here. The operating handle 100 includes the aforementioned housing 110 and electronic components 120, which are installed in the receiving cavity 111. The conductive element 113 of the housing 110 can block the gap 112 to prevent electrostatic charges from damaging the electronic components 120.

[0039] In another embodiment, the operating handle 100 includes the aforementioned housing 110, electronic component 120, and cable 140, thus enabling the operating handle 100 to possess the beneficial effects of any of the aforementioned solutions, which will not be elaborated further here. The electronic component 120 is installed in the receiving cavity 111, and the cable 140 is installed in the cable mounting port 115 of the housing 110. The first clamping portion 1135 of the housing 110 clamps the cable 140, and the conductor can block the gap 112 of the cable mounting port 115.

[0040] In another embodiment, the operating handle 100 includes the aforementioned housing 110, electronic component 120, negative pressure connector 130, and cable 140, thus enabling the operating handle 100 to possess the beneficial effects of any of the aforementioned solutions, which will not be elaborated further here. The cable 140 is installed in the cable mounting port 115 of the housing 110, the negative pressure connector 130 is installed in the instrument mounting port 116 of the housing 110, the electronic component 120 is installed in the receiving cavity 111, the first clamping portion 1135 of the housing 110 clamps the cable 140, and the second clamping portion 1138 of the housing 110 clamps the negative pressure connector 130. A conductor can block the gap 112 between the cable mounting port 115 and the instrument mounting port 116.
