Description

Technical Field

[0001] This utility model relates to the field of otolaryngological endoscope technology, specifically a split-type otolaryngological endoscope. Background Technology

[0002] Existing otolaryngological endoscopes include two main types: rigid and flexible, each with different applications and characteristics. Rigid endoscopes generally offer higher image quality and more stable operation, but their rigid structure limits their flexibility within the body; while flexible endoscopes are known for their flexibility, allowing access to more complex areas, but their image quality and operational stability may be slightly inferior.

[0003] However, both rigid and flexible endoscopes are one-piece structures, and there are many models of endoscopes. Each model requires a complete set of main unit and application terminals, which results in high costs. Furthermore, the one-piece structure is not convenient for repair and replacement, so the disadvantages of the one-piece structure are very obvious.

[0004] In summary, current ENT endoscopes face challenges such as diverse models and the inconvenience of disassembly, maintenance, and parts replacement due to their integrated design, resulting in high costs and low efficiency. Therefore, there is an urgent need for a modular ENT endoscope to solve these technical problems. Utility Model Content

[0005] This invention provides a split-type ENT endoscope that allows for quick assembly and disassembly of the application end and the host end, thus solving the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a split-type ENT endoscope, comprising: a detachable application end and a main unit end. The main unit end has a mounting groove on the top of the handle. The application end is fitted with a mounting part that matches the mounting groove. The mounting part is plugged in and detached with one key. The bottom of the mounting groove is provided with a card seat. The card seat is provided with several electrically connected contact pins. The mounting part is provided with a matching card slot corresponding to the card seat. The card slot is provided with several electrically connected contact points matching the contact pins. The shape and size of the contact positions of the mounting groove and the mounting part are matched. After the application end and the main unit end are connected, they fit tightly together, and the contact pins and contact points are surrounded inside each other while in contact.

[0007] This split-type ENT endoscope allows for quick assembly and disassembly of the application end and the main unit. Different application ends can be replaced while the main unit itself remains functional, making it highly versatile. Combined with the replaceable application end, only one main unit is needed to connect to different models of application ends, reducing costs and making repairs or replacements more convenient.

[0008] As an optional solution for the split-type ENT endoscope described in this utility model, the bottom of the mounting groove is an arc-shaped surface, the outer side of the mounting part matches the mounting groove as an arc-shaped protrusion, the slot is opened at the top of the arc-shaped protrusion, the slot is an arc-shaped structure, the slot corresponds to the slot as an arc-shaped groove, and the bending angle of the slot is adapted to the arc-shaped surface of the bottom of the mounting groove.

[0009] As an optional solution for the split-type ENT endoscope described in this utility model, the top of the two sides of the card seat along the arc-shaped bending direction is provided with guide ribs, and the card slot is provided with guide grooves corresponding to the guide ribs. This structural design facilitates insertion and removal during installation.

[0010] As an optional solution for the split-type ENT endoscope described in this utility model, the main unit is provided with a locking tongue, and the application unit is provided with a locking hole plate to match the locking tongue. After the application unit and the main unit are connected, the locking tongue is locked into the locking hole plate to lock the two together. The unlocking button is located on the main unit.

[0011] This utility model has the following beneficial effects:

[0012] 1. This split-type ENT endoscope allows for quick assembly and disassembly of the application end and the main unit. Different application ends can be replaced while the main unit itself remains functional, making it highly versatile. Combined with the replaceable application end, only one main unit is needed to connect to different models of application ends, reducing costs and making repairs or replacements more convenient.

[0013] 2. After the application end and the main unit of this split-type ENT endoscope are connected, there is almost no change to the external appearance. The internal space of the application end and the main unit are reasonably utilized to improve the structure and realize the connection structure design of the two. It does not affect the use of the endoscope at all and does not require major modifications to existing products. Therefore, it has strong applicability. Attached Figure Description
