Description

Technical Field

[0001] This utility model belongs to the field of cable assembly technology, specifically relating to a medical waterproof endoscope cable assembly. Background Technology

[0002] Medical endoscopes, as precision medical devices, are used for observation, diagnosis, and treatment inside human cavities or wounds. Endoscope cables are crucial components connecting the endoscope main unit and the endoscope handle, playing a vital role in image transmission. Because surgical procedures require sterile conditions, endoscope cables used in surgical procedures must meet high sterilization requirements. Currently, endoscope cables are generally sterilized using ethylene oxide or chemical baths and are reused after sterilization. Since the sterilization process involves immersion in a water-containing environment, endoscope cables must possess a certain degree of waterproofing. Water ingress into the endoscope cables will render the endoscope unusable.

[0003] Endoscope cables typically include a main unit, which connects to the endoscope unit. The main unit includes a housing and a cable sheath. A sealing ring is provided between the housing and the cable sheath to achieve waterproofing.

[0004] However, in actual use, endoscope cables are often bent and twisted, which may cause slight deformation of the cable sheath or relaxation of the sealing ring stress, resulting in gaps at the sealing interface of the sealing ring and compromising the sealing performance of the main unit. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a medical waterproof endoscope cable assembly. By sealing the outer and inner waterproof grooves with a sealant, external moisture is difficult to enter the inner shell and affect the cable. This helps to ensure the waterproof performance of the medical waterproof endoscope cable assembly and extend its service life.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects: This utility model provides a medical waterproof endoscope cable assembly, including a main unit and a cable. The main unit includes: a body, including a connecting end and a plug-in end; an inner shell, sleeved on the connecting end, with an outer waterproof groove formed between the inner shell and the plug-in end, and an inner waterproof groove formed on the inner shell, the cable passing through the interior of the inner shell; and a sealing element for sealing the outer waterproof groove and the inner waterproof groove.

[0007] In some implementations, the seal includes an injection-molded mesh tail that covers the outside of the inner shell and fills the outer waterproof groove and the inner waterproof groove.

[0008] In some implementations, a connecting groove is provided on the connecting end, and a sealing end is formed by a protrusion on the inner wall of the inner shell. The sealing end is located in the connecting groove and is adapted to the connecting groove.

[0009] In some implementations, the inner shell includes a first shell and a second shell, the first shell and the second shell being fitted together on the connecting end, and the cable passing between the first shell and the second shell.

[0010] In some implementations, the first housing has a fitting groove, and the second housing has a fitting portion, and the first housing and the second housing fit together through the fitting groove and the fitting portion.

[0011] In some implementations, the second housing has an injection hole, and a waterproof adhesive layer is filled between the first housing and the second housing, with the cable passing through the waterproof adhesive layer.

[0012] In some implementations, a fixing block is provided on the inner wall of the first housing, and a connector is provided between the second housing and the fixing block inside the glue injection hole.

[0013] In some implementations, a host-end circuit board is inserted inside the main body, the host-end circuit board extends into the inner shell, and a locking hole is provided on the host-end circuit board. The connector passes through the injection hole and the locking hole and is detachably connected to the fixing block.

[0014] In some implementations, a pressure plate for fixing the cable is provided on the inner wall of the first housing, and the pressure plate is detachably connected to the first housing.

[0015] In some implementations, a handle end is provided on the side of the cable away from the host end, and the handle end is connected to the cable.

[0016] In summary, this utility model has at least the following advantages: This utility model provides a waterproof medical endoscope cable assembly. An inner shell is fitted onto the connecting end, and a sealant seals both the outer and inner waterproof grooves. The sealant forms a first layer of waterproofing at the outer waterproof groove and a second layer at the inner waterproof groove. This double waterproof seal enhances the waterproof performance at the connection between the inner shell and the main body. The waterproof medical endoscope cable assembly can be sterilized in liquid environments. Compared to traditional endoscope cables, the sealant provides a tighter connection with the main body and inner shell, solving the problem of water ingress after repeated bending and twisting of the endoscope cable, thus ensuring the sealing performance of the main unit.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Example 1: This utility model discloses a waterproof medical endoscope cable assembly, which is used in medical endoscopes to connect the endoscope main unit and the endoscope handle, and has good waterproof performance.

[0025] Please see Figures 1-3The medical waterproof endoscope cable assembly of this utility model includes a main unit 1 and a cable 2. The main unit 1 includes a body 11, which includes a connecting end 111 and a plug-in end 112. In some specific embodiments, the connecting end 111 passes through the inside of the plug-in end 112 and extends to the outside of the plug-in end 112. The body 11 is connected to the endoscope main unit through the plug-in end 112.

[0026] An inner shell 12 is fitted onto the connector 111, and the cable 2 passes through the interior of the inner shell 12. An outer waterproof groove 113 is formed between the inner shell 12 and the connector 112. Specifically, the outer waterproof groove 113 is an annular groove arranged around the connector 111. An inner waterproof groove 121 is formed on the inner shell 12. The inner waterproof groove 121 is specifically an elongated groove. Multiple inner waterproof grooves 121 can be provided, and multiple inner waterproof grooves 121 are located at the top and bottom of the inner shell 12, respectively.

[0027] A sealing element 13 is provided on the outer side of the inner shell 12. The sealing element 13 seals the outer waterproof groove 113 and the inner waterproof groove 121, which can prevent moisture from entering the interior of the inner shell 12 and thus affecting the cable 2. The sealing element 13 is tightly connected to the main body 11 and the inner shell 12 through the outer waterproof groove 113 and the inner waterproof groove 121, which plays an effective sealing role. Even after repeated bending and twisting, the sealing interface of the sealing element 13 at the outer waterproof groove 113 and the inner waterproof groove 121 can still be ensured to be seamless. The medical waterproof endoscope cable assembly has excellent waterproof performance, can be repeatedly disinfected and used, and has an extended service life.

[0028] Example 2: The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the sealing element 13 of this utility model. Please refer to [link / reference]. Figures 1-3 .

[0029] The sealing element 13 in this embodiment includes an injection-molded mesh tail. Specifically, the injection-molded mesh tail can be made of silicone. After the inner shell 12 and the main body 11 are assembled, they are placed in the mold of the injection molding machine, and the injection-molded mesh tail is injection molded. During the injection molding process, the injection-molded mesh tail penetrates into the outer waterproof groove 113 and the inner waterproof groove 121 to fill the outer and inner waterproof grooves 121. After injection molding, the injection-molded mesh tail covers the outside of the inner shell 12 and seals the outer waterproof groove 113 and the inner waterproof groove 121, ensuring the sealing of the connection between the main body 11 and the inner shell 12. Specifically, the depth of the outer waterproof groove 113 can be 0.25 mm. This is not a specific limitation on the depth of the outer waterproof groove 113. Those skilled in the art can adjust the depth of the outer waterproof groove 113 according to the actual dimensions of the main body 11 and the inner shell 12.

[0030] Specifically, the injection-molded mesh tail can cover the cable 2 to further improve waterproof performance. In some other specific embodiments, a connecting groove is provided between the inner waterproof groove 121 and the outer waterproof groove 113. The connecting groove is connected to the inner waterproof groove 121 and the outer waterproof groove 113 respectively. When the injection-molded mesh tail is injected, it can penetrate into the connecting groove to enhance the overall structural strength of the injection-molded mesh tail and further improve the problem of weakened sealing caused by bending and twisting of the medical waterproof endoscope cable assembly.

[0031] Please see Figure 3 In some specific embodiments, a connecting groove 114 is provided on the connecting end 111, which is located on one side of the outer waterproof groove 113. A sealing end 122 is formed by a protrusion on the inner wall of the inner shell 12, which is located inside the connecting groove 114 and is adapted to the connecting groove 114. The sealing end 122 cooperates with the connecting groove 114 to improve the waterproof performance at the connection between the inner shell 12 and the connecting end 111, and to limit the entry of moisture into the interior of the inner shell 12 during the sterilization of the medical waterproof endoscope cable assembly. The structure is simple.

[0032] Example 3: The difference between this embodiment and the above embodiments is that this embodiment further optimizes the structure of the inner shell 12 of the present invention.

[0033] Please see Figure 3 In this embodiment, the inner shell 12 includes a first shell 123 and a second shell 124. The first shell 123 and the second shell 124 are combined and sleeved on the connecting end 111. The cable 2 passes between the first shell 123 and the second shell 124. The first shell 123 and the second shell 124 are detachably connected, which facilitates the assembly of the inner shell 12 and the connecting end 111.

[0034] In a preferred embodiment, the first housing 123 is provided with a fitting groove 1231, and the second housing 124 protrudes to form a fitting portion 1241. The first housing 123 and the second housing 124 are fitted together by the fitting groove 1231 and the fitting portion 1241. During assembly, the first housing 123 can be sleeved on the connecting end 111, and then the second housing 124 can be fastened. The fitting portion 1241 and the fitting groove 1231 realize the initial positioning of the first housing 123 and the second housing 124, and the first housing 123 and the second housing 124 can be quickly assembled.

[0035] In some specific embodiments, the first housing 123 has an injection hole 1242, and a waterproof adhesive layer is filled between the first housing 123 and the second housing 124. After the first housing 123 is fitted onto the connecting end 111, the cable 2 can be threaded through the first housing 123 before the second housing 124 is closed. The second housing 124 is connected to the first housing 123. Waterproof adhesive is injected into the space between the first housing 123 and the second housing 124 through the injection hole 1242. The waterproof adhesive layer solidifies, and the cable 2 is threaded through the waterproof adhesive layer. The waterproof adhesive layer provides waterproofing inside the inner housing 12, protecting the electrical connection end of the cable 2.

[0036] In some specific embodiments, a fixing block 1232 is provided on the inner wall of the first housing 123, and a connector is provided between the second housing 124 and the fixing block 1232 in the glue injection hole 1242, thereby achieving a detachable connection with the first housing 123 through the connector. Furthermore, the connector can be a screw, and a screw hole is provided on the fixing block 1232, through which the screw passes and is threadedly connected to the fixing block 1232.

[0037] Please see Figure 2 The main body 11 houses a main unit circuit board 3 that connects to the endoscope host. The main unit circuit board 3 extends into the inner shell 12 and has a locking hole 31. Screws pass through the glue injection hole 1242 and the locking hole 31 and are threadedly connected to the fixing block 1232, thus fixing the main unit circuit board 3. At the same time, the cable 2 is electrically connected to the main unit circuit board 3.

[0038] In some specific embodiments, a pressure plate 125 for fixing the cable 2 is provided on the inner wall of the first housing 123. The pressure plate 125 is specifically an arc-shaped plate. When the cable 2 is placed in the first housing 123, the pressure plate 125 presses the cable 2. The pressure plate 125 is detachably connected to the first housing 123, and the cable 2 is positioned.

[0039] Example 4: The difference between this embodiment and the above embodiments is that, please refer to [link / reference needed]. Figure 1 In this embodiment, a handle end 4 is provided on the side of the cable 2 away from the main unit end 1. The handle end 4 is connected to the cable 2, and the medical waterproof endoscope cable assembly can be plugged into the endoscope handle through the handle end 4.

[0040] In some specific embodiments, the handle end 4 includes a sleeve, and a circuit board for the handle end 4 is inserted through the sleeve.
