0/30/ 70 Degree Medical Rigid Ent Endoscope

1.Optical system

Objective Lens group

It is located at the front end of the endoscope and directly contacts the observed target. Composed of multiple groups of lenses, it is responsible for capturing images and transmitting them to the image transmission system.

Features: It should have high resolution, anti-pollution design (such as anti-fog coating), wide Angle or specific field of view (such as 0°, 30°, 70°, etc.).

Image Transmission System

Rod Lens System: Composed of a series of precise cylindrical lenses, it transmits images through refraction and maintains high clarity (such as the Storz-Hopkins system).

Fiber Optic Bundle: Some endoscopes use flexible fiber optic bundles for image transmission, but hard endoscopes are mainly rod-shaped lenses.

Eyepiece Lens

It is located at the end of the endoscope, allowing doctors to directly observe or connect camera equipment. The diopter can be adjusted to suit the vision of different users.

2. Mechanical structure

Insertion Tube

Material: High-strength stainless steel or titanium alloy, ensuring rigidity and disinfection resistance.

Diameter: Commonly 2mm to 10mm, designed according to the application (such as laparoscopy, sinus endoscopy).

Length: Customized according to surgical requirements (for example, shorter urological endoscopes and longer laparoscopes).

Working Channel (Available in some models)

It is used for inserting surgical instruments (such as biopsy forceps, electrocoagulation probes) and is usually designed as a straight-through type.

1. Otology

External auditory canal and tympanic membrane examination: Observe external auditory canal inflammation, foreign bodies, cerumen impaction, tympanic membrane perforation, effusion, etc.

Middle ear surgery: It assists in minimally invasive operations such as tympanoplasty and ossicular chain reconstruction Biopsy of ear tumors or lesions: Precisely locate and sample suspicious tissues.

2. Rhinology

Nasal cavity and paranasal sinus examination: Diagnosis of deviated nasal septum, nasal polyps, rhinitis, sinusitis, etc.

Endoscopic nasal surgery (FESS) : It is used for functional sinus surgery, polyp removal, nasal conchal volume reduction, etc.

Management of epistaxis: Locate the bleeding point and assist with electrocoagulation to stop the blood.

Nasopharyngeal tumor screening: such as the early detection of nasopharyngeal carcinoma

3. Laryngology & Pharyngology

Laryngeal examination: Evaluate vocal cord polyps, nodules, cysts and laryngeal tumors.

Removal of foreign body in the throat: Safely remove the foreign body under direct vision.

Voice surgery: Supports fine operations such as vocal cord injection and laser surgery.

Assessment of sleep apnea syndrome (OSA) : Observe the location of airway stenosis or obstruction.

4. Other extended applications

Pediatric ENT diseases: Suitable for congenital ear, nose and throat malformations or the removal of foreign bodies in children.

Postoperative follow-up: Minimally invasive follow-up of surgical effects (such as after sinus opening surgery).

Teaching and research: It is used for clinical teaching, case recording and medical research.

Q:What is an ENT rigid endoscope?
A:An ENT rigid endoscope is a straight, tubular optical instrument used to examine the ear, nose, throat, and surrounding structures. It provides high-quality, magnified images and is commonly used for diagnostic and surgical procedures.

Q:How does it differ from a flexible endoscope?
A:Rigid endoscopes are straight and do not bend, offering superior image clarity and durability. Flexible endoscopes can bend and navigate curved pathways, making them suitable for different clinical scenarios. The choice depends on the specific examination or procedure needs.

Q: How should I clean and sterilize the endoscope?
A:Follow the manufacturer’s guidelines. Typically, post-use cleaning involves immediate rinsing, enzymatic detergent cleaning, and thorough drying. Sterilization methods may include autoclaving (if heat-tolerant), chemical sterilization, or low-temperature plasma sterilization. Always inspect for damage before reuse.

Q:Can rigid endoscopes be repaired if damaged?
A:Yes, many damages (e.g., lens scratches, light guide issues) can be repaired by specialized technicians. Contact the manufacturer or an authorized service center for assessment. Regular maintenance helps prolong the instrument’s lifespan.

Q:What are the advantages of using rigid endoscopes?

• Excellent optical clarity and bright images

• Robust and long-lasting construction

• Suitable for precise surgical interventions

• Often more cost-effective than flexible scopes for specific procedures

  
  

Q:Are there any limitations?
Due to their rigid structure, they cannot navigate tortuous anatomy. They may also require more patient cooperation or anesthesia during certain examinations.

Q:How do I choose the right rigid endoscope?
Consider factors such as diameter, length, viewing angle (0°, 30°, 70°, etc.), intended use, compatibility with light sources and cameras, and budget. Consult with clinical specialists or the manufacturer for guidance.

Q: How long is the delivery?

A: Usually 15-30 days after order confirmation plus advanced payment or L/C arrived for standard models. Customized orders may take longer and need discussion.
