Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a side-opening laryngoscope. Background Technology

[0002] Because the larynx is located deep within the throat and has a complex physiological structure, it cannot be directly visualized. Therefore, special examination methods are required. Generally, a laryngoscope is inserted into the larynx to widen the larynx. The laryngoscope is held in place by hand, and the endoscope tube is inserted into the viewing tube of the laryngoscope. The laryngoscope is held in place by hand while observing the condition of the affected area. Surgical instruments are then inserted through the viewing tube of the laryngoscope to perform the surgery.

[0003] Existing laryngoscope viewing tubes, such as the easy-to-operate viewing tube in patent publication number CN 219184062U, have a completely closed arc-shaped tube. According to feedback from hospital doctors, in simple outpatient surgeries, such as removing foreign objects from the larynx or trachea, the completely closed viewing tube obstructs the surgical field of vision, making the surgery more difficult and prolonging the operation time. Utility Model Content

[0004] To address the above problems, this invention designs a side-opening laryngoscope, which has the advantages of expanding the surgical field of view and facilitating surgical operations.

[0005] The technical solution of this utility model is as follows: a side-opening laryngoscope, including a handle, a handle seat fixedly provided on the handle, a viewing tube assembly movably installed on the handle seat, the viewing tube assembly including a tube, the tube having a side-opening structure with a radius greater than 1 / 2 arc, the front end of the tube having a downward transition arc-shaped end face to facilitate entry into the larynx, and the rear end of the tube having a tube seat that cooperates with the handle seat.

[0006] In the aforementioned side-opening laryngoscope, the intubation port is provided with an optical fiber tube extending to the side wall of the intubation tube. An optical fiber is installed in the optical fiber tube. When one end of the optical fiber tube is connected to a light source, the other end is an illumination part that can emit light to illuminate the lesion area of ​​the larynx.

[0007] In the aforementioned side-opening laryngoscope, a mounting rod is provided on the front side of the handle seat, and two mounting holes are provided on the rear side of the handle seat.

[0008] The front side of the insertion tube seat is provided with a mounting slot corresponding to the mounting rod; the two sides of the insertion tube seat are provided with top ball holes corresponding to the mounting holes on the handle seat, and the top ball holes are provided with mounting springs and top balls.

[0009] In the aforementioned side-opening laryngoscope, the illumination section of the optical fiber tube is located in the front middle part of the insertion tube, and a light-transmitting groove is provided in the insertion tube on the side with the optical fiber tube, with the end face of the light-transmitting groove located behind the illumination section of the optical fiber tube.

[0010] In the aforementioned side-opening laryngoscope, a light source connector is provided on the lower side of the handle, an optical fiber channel is provided inside the handle, and an optical fiber is provided inside the optical fiber channel; an optical fiber port is provided inside the handle seat, and the optical fiber port is correspondingly connected to the optical fiber tube port inside the cannula seat.

[0011] Compared with the prior art, the cannula of this utility model has a side-opening structure, which facilitates the operation of other instruments during surgery and expands the surgical field;

[0012] Furthermore, an optical fiber tube extends to the side wall of the intubation tube, illuminating the lesion area of ​​the throat, which is convenient for outpatient doctors to observe directly, and can also be used for simple surgeries such as foreign body removal.

[0013] Furthermore, the viewing tube assembly is detachably connected to the handle, facilitating cleaning and disinfection of the viewing tube assembly. It can also be equipped with multiple viewing tube assemblies of different sizes to suit the throats of different people.

[0014] In summary, this utility model has the advantages of expanding the surgical field of view and facilitating surgical operations. Attached Figure Description
