Abstract
Description
Technical Field
[0001] This utility model relates to the field of confocal probe technology, and in particular to a fiber optic probe protection structure. Background Technology
[0002] A confocal endoscopy system is a device used for clinical microscopic observation of the human body. It consists of a confocal main unit and a confocal probe. The confocal probe needs to be connected to the fiber optic coupler of the confocal main unit via a connector to complete the transmission of optical signals. The confocal connector consists of a handle, a plug, and a bundle of optical fibers.
[0003] Optical fiber is a very precise communication device. The plug is the physical interface used to connect the optical fiber. The plug must also be very precise and cannot be contaminated. Therefore, an end cap needs to be put on the plug to prevent the disinfectant from coming into contact with the probe during the disinfection process and to prevent dust.
[0004] The existing end caps are made of rigid materials and have cylindrical slots. The plug is inserted into the slots and forms an interference fit with the end cap, which can easily cause the end caps to detach during high-temperature sterilization. Utility Model Content
[0005] The main purpose of this invention is to propose a fiber optic probe protection structure, which aims to solve the problem that existing end caps are easily detached from the plug.
[0006] To achieve the above objectives, the present invention proposes a fiber optic probe protection structure, including an end cap made of an elastic material, the end cap having an axial slot, the slot including an insertion port and a limiting boss communicating with the insertion port.
[0007] In one embodiment, the slot further includes a stepped hole communicating with the insertion port. The stepped hole includes a small-diameter hole connected to the insertion port and a large-diameter hole connected to the small-diameter hole. The connection between the small-diameter hole and the large-diameter hole forms the limiting boss.
[0008] In one embodiment, both the small-diameter hole and the large-diameter hole are cylindrical through holes.
[0009] In one embodiment, the slot further includes a receiving cavity communicating with the stepped hole, the diameter of which is smaller than the diameter of the large-diameter hole.
[0010] In one embodiment, the receiving cavity is a cylindrical cavity with one end open.
[0011] In one embodiment, the diameter of the insertion port gradually decreases along the direction of the insertion path.
[0012] In one embodiment, the end cap is made of silicone or rubber.
[0013] In one embodiment, the fiber optic probe protection structure further includes a hanging hole disposed on the end cap.
[0014] In one embodiment, the fiber optic probe protection structure further includes a positioning sleeve, which is connected to the end cap via a connector.
[0015] In one embodiment, the fiber optic probe protection structure further includes a fiber optic storage sleeve connected to the positioning sleeve.
[0016] In this invention, the end cap is made of an elastic material. The plug is inserted into the slot through the insertion port, causing the end cap to undergo a certain elastic deformation, thus ensuring that the end cap is stably fitted onto the plug. During high-temperature sterilization, this effectively prevents the end cap from detaching from the plug. Furthermore, a limiting protrusion is provided in the slot, which can contact the end of the plug, further preventing the end cap from detaching from the plug. Attached Figure Description

[0030] Existing end caps are made of rigid materials and have cylindrical slots. The plug is inserted into the slot, forming an interference fit with the end cap. However, this makes the end cap prone to detaching during high-temperature sterilization. Therefore, this invention proposes a fiber optic probe protection structure to solve the problem of existing end caps easily detaching from the plug.
[0031] Please see Figures 1 to 3 In one embodiment of the present invention, the fiber optic probe protection structure 100 includes an end cap 1, the end cap 1 being made of an elastic material, the end cap 1 having an axial slot 11, the slot 11 including an insertion port 111 and a limiting boss 115 communicating with the insertion port 111.
[0032] By adopting the above technical solution, the end cap 1 is made of an elastic material, and the plug 24 is inserted into the slot 11 through the insertion port 111, causing the end cap 1 to undergo a certain elastic deformation, so that the end cap 1 is stably fitted onto the plug 24. During high-temperature sterilization, this effectively prevents the end cap 1 from detaching from the plug 24. Furthermore, a limiting boss 115 is provided in the slot 11, which can contact the end 241 of the plug, further preventing the end cap 1 from detaching from the plug 24.
[0033] Furthermore, in order to better limit the plug 24 and prevent the end cap 1 from separating from the plug 24, in this utility model, the slot 11 further includes a stepped hole communicating with the insertion port 111. The stepped hole includes a small diameter hole 112 connected to the insertion port 111 and a large diameter hole 113 connected to the small diameter hole 112. The connection between the small diameter hole 112 and the large diameter hole 113 forms the limiting boss 115.
[0034] By adopting the above technical solution, along the direction of the insertion path, the slot 11 includes an insertion port 111, a small diameter hole 112 and a large diameter hole 113 connected in sequence. The small diameter hole 112 is used to accommodate the conduit 23 of the fiber optic probe 200. The circumferential outer wall of the plug 24 fits against the inner wall of the large diameter hole 113, and the end 241 of the plug fits against the limiting boss 115 to effectively prevent the plug 24 in the slot 11 from coming loose.
[0035] Specifically, both the small-diameter hole 112 and the large-diameter hole 113 are cylindrical through holes. The small-diameter hole 112 and the large-diameter hole 113 are both cylindrical through holes to better fit the contours of the plug 24 and the conduit 23.
[0036] Furthermore, in order to better accommodate the end 242 of the plug, the slot 11 also includes a receiving cavity 114 communicating with the stepped hole, the diameter of the receiving cavity 114 being smaller than the diameter of the large-diameter hole 113.
[0037] By adopting the above technical solution, the plug 24 is inserted into the slot 11 of the end cover 1 through the insertion port 111. The end 242 of the plug is located in the receiving cavity 114. The diameter of the receiving cavity 114 is smaller than the diameter of the large diameter hole 113, so that another limiting boss is formed between the receiving cavity 114 and the large diameter hole 113. The middle part of the plug 24 fits against the limiting boss, which can effectively ensure that the outer wall of the section from the middle part of the plug to the end 242 of the plug fits more stably against the inner wall of the large diameter hole 113.
[0038] Specifically, the receiving cavity 114 is a cylindrical cavity with one end open. The receiving cavity 114 is a cylindrical structure with one end open and the other end closed, and its open end is connected to the large-diameter hole 113 so that the end 242 of the plug can be better inserted into the receiving cavity 114.
[0039] Furthermore, to facilitate the insertion of the plug 24 into the slot 11, in the technical solution of this utility model, the diameter of the insertion port 111 gradually decreases along the insertion path. The insertion port 111 is funnel-shaped, which facilitates the insertion of the plug 24 into the slot 11.
[0040] Furthermore, the end cap 1 is made of silicone or rubber. Using silicone or rubber, which are elastic materials, to make the end cap 1 can better give the end cap 1 a certain elastic deformation property, which can not only make the plug 24 more stably inserted into the slot 11, but also effectively prevent the plug 24 from detaching from the end cap 1 during high-temperature sterilization.
[0041] Furthermore, the fiber optic probe protection structure 100 also includes a hanging hole 12 provided on the end cap 1. The hanging hole 12 on the end cap 1 facilitates hanging the fiber optic probe protection structure on the trolley, improving the convenience of operation.
[0042] Furthermore, the fiber optic probe protection structure 100 also includes a positioning sleeve 14, which is connected to the end cap 1 via a connector 13. The positioning sleeve 14 is used to fix the fiber optic probe protection structure to the handle 22. In use, first fix the fiber optic probe protection structure to the handle 22 via the positioning sleeve 14, then insert the plug 24 into the slot 11. See the usage instructions for reference. Figure 4 and Figure 5 .
[0043] Furthermore, the fiber optic probe protection structure 100 also includes a fiber optic storage sleeve 15 connected to the positioning sleeve 14. After the end of the handle 22 is inserted into the positioning sleeve 14, the probe 2 can pass through the fiber optic storage sleeve 15, so that a section of fiber optic bundle 21 between the probe 2 and the handle 22 is located inside the fiber optic storage sleeve 15, so as to better store the fiber optic bundle 21.
[0044] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
