Drag hook for nasal endoscope

Abstract

The invention provides a drag hook for a nasal endoscope. The drag hook comprises a main body part (1) of the drag hook with a connection end and an open end, an insert part (2) and an endoscope fixing part (3). The insert part (2) is arranged at the connection end of the main body part (1) of the drag hook and can be detached relative to the main body part (1) of the drag hook. The endoscope fixing part (3) is arranged on the bottom surface of the main body part (1) of the drag hook and can be detached relative to the main body part (1) of the drag hook. A single operator can perform hook-dragging operation and illuminates a surgical field while conducting an operation on the nose. Furthermore, the drag hook for the nasal endoscope serves different functions.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to the field of medical instruments for nasal inspection and nasal surgery, in particular to a retractor for nasal endoscope. Background technique [0002] In the process of nose inspection or nose surgery, due to the complexity and particularity of the nose structure, it is necessary to use various auxiliary tools, for example, nasal endoscope is commonly used in functional endoscopic surgery Wait. [0003] When nasal endoscopy is used clinically, in order to observe the nose clearly and reliably for surgery, it is usually necessary to use other auxiliary tools such as strippers, small retractors, nasal retractors, etc. to pull apart the nasal septal mucosa or nasal dorsal flap for surgical The field of view is exposed in the field of view, which is convenient for lighting and observation of the operation field, so that the operation can be performed more accurately and smoothly...

AI Technical Summary

Problems solved by technology

At this time, due to the influence of the assistant's experience and tacit understanding with the operator, sometimes the assistant's auxiliary work does not meet the operator's requirements, which not only affects the smooth progress of the operation, but also sometimes because the assistant did not understand the operator's intention resulting in reduced surgical accuracy

In addition, there is a huge waste not only in the configuration of personnel, but also affects the accuracy of the operation, and sometimes wastes time for no reason

[0008] In addition, the retractors in the prior art all correspond to one type and one type of retractors, and different models and types of retractors need to be prepared each time to perform surgery, making the auxiliary equipment used for surgery complicated and cumbersome
