Paranasal sinus mucosa hook

Abstract

The invention relates to the field of medical apparatus and instruments, and discloses a paranasal sinus mucosa hook. The paranasal sinus mucosa hook comprises a holding handle, wherein the outer wallof the holding handle is sheathed with an anti-skidding cover; the top end of the holding handle is fixedly provided with a first handle; the right side of the first handle is fixedly provided with an inner pulling rod; the outer wall of the inner pulling rod is sheathed with a second handle; the outer wall of the inner pulling rod is sheathed with a first spiral limit valve; the outer wall of the inner pulling rod is sheathed with a second spiral limit valve; the inner wall of the second spiral limit valve is movably connected with an outer casing pipe; and the left side of the outer casingpipe is fixedly provided with a connecting block. Since the paranasal sinus mucosa hook is of a handheld long rod shape, the paranasal sinus mucosa hook can easily penetrate into the paranasal sinus for operating, the hook is designed into a structure that a hook blade and a groove are matched, while surrounding normal mucosa and soft tissues are protected, a shearing success rate and stability ofthe mucosa can be guaranteed, repeated and meaningless operations and injuries are avoided, the physical strength of an operator is saved, and operating time is shortened.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a sinus mucosal hook knife. Background technique [0002] Paranasal sinuses, also known as paranasal sinuses or paranasal sinuses, are the general term for the air-containing cavities in the skull (frontal bone, sphenoid bone, maxilla, and ethmoid bone) around the nasal cavity. There are sinus openings that communicate with the nasal cavity and resonate with pronunciation , The sinuses are paired left and right, a total of four pairs, called the frontal sinus, maxillary sinus, sphenoid sinus and ethmoid sinus. [0003] The space of transsphenoidal surgery is deep and narrow, ordinary micro scissors cannot operate deeply, and hook knife is often used for sinus mucosal treatment, and the use of hook knife in sinus cavity requires high technical skills for the surgeon, and it may be slightly difficult if there is no support point. If you are not careful, the hook knife will slip ...

AI Technical Summary

Problems solved by technology

[0003] The space of transsphenoidal surgery is deep and narrow, ordinary micro-scissors cannot operate deeply, and hook knife is often used for sinus mucosal treatment, and the use of hook knife in sinus cavity has high technical requirements for the surgeon, and it may be slightly difficult if there is no support point. If you are not careful, the hook knife will slip off from the mucous membrane, and often after repeated operations, it will inevitably cause unnecessary damage to the surrounding mucous membrane and soft tissue, and even bleeding will not stop. Electrocoagulation is required to stop bleeding and local burns. The traditional hook knife has a simple structure. The operation is inconvenient and the stability is poor, especially for young doctors, it is easy to cause unnecessary cutting damage to the surrounding normal tissues, and even bring unpredictable consequences
