Autoclavable 0/30/70 Degree Rigid Digital Cystoscope

The structure composition of Rigid Cystoscope

1.Optical mirror (mirror body)

Function: Core imaging component, composed of a series of precision lenses, is responsible for conducting internal images to the eyepiece or camera.

Features:

It is usually a hard metallic tubular structure with optical fibers or lens groups inside.

Some designs include viewing angles (such as 0°, 30°, 70°) to accommodate different observation angles.

2. Mirror sheath

Function:

Protect the optical lens to avoid direct contact with the tissue and cause damage.

Provide access channels for instruments (such as the entry and exit paths for biopsy forceps and electrocoagulation instruments).

It may integrate a flushing/suction channel for removing liquids or impurities in the field of view.

Features:

The diameters are diverse (for example, the sheath of urology is relatively thick, while that of pediatrics is relatively thin).

Some of the mirror sheaths can rotate for easy operation.

3. Closed-cell device

Function:

When inserting into the body cavity, temporarily close the front end of the sheath to avoid tissue damage (such as urethral mucosa).

Reduce the frictional resistance during the insertion process.

The application scope of Rigid Cystoscope

1. Diagnostic Applications

• Evaluation of Hematuria (blood in urine) – To identify bladder tumors, stones, or inflammation.

• Bladder Tumor Detection – Visual inspection and biopsy of suspicious lesions.

• Chronic Urinary Symptoms – Investigating causes of frequent UTIs, dysuria, or urinary retention.

• Stricture Assessment – Examining urethral or bladder neck narrowing.

• Foreign Body Identification – Detecting and removing objects in the bladder.

2. Therapeutic Applications

• Transurethral Resection of Bladder Tumor (TURBT) – Removal of small bladder tumors.

• Bladder Stone Removal – Lithotripsy (breaking up stones) and extraction.

• Treatment of Urethral Strictures – Dilation or internal urethrotomy.

• Prostate Procedures – Managing bladder outlet obstruction (e.g., in benign prostatic hyperplasia).

• Fulguration of Bleeding Lesions – Cauterization of abnormal blood vessels or small tumors.

• Catheter Placement – Guiding difficult urethral or ureteral catheter insertions.

3. Specialized Uses

• Biopsy Collection – Taking tissue samples for histopathology.

• Intravesical Therapy – Administering medications (e.g., BCG for bladder cancer).

• Evaluation of Congenital Anomalies – In pediatric or adult urology (e.g., posterior urethral valves).

Advantages Over Flexible Cystoscope

• Better Optical Clarity – Provides a sharper, wider field of view.

• Larger Working Channel – Allows for more instruments (e.g., resectoscopes, forceps).

• Superior Maneuverability for Certain Procedures – Especially in resections and stone management.

1. What is a Rigid Cystoscope?

A rigid cystoscope is a straight, non-flexible endoscope used by urologists to examine the bladder and urethra. It consists of a metal sheath, an optical lens, and a light source, allowing for high-quality visualization and surgical procedures.

2. How does a Rigid Cystoscope differ from a Flexible Cystoscope?

• Rigid Cystoscope: Provides better image quality, is more durable, and is typically used for diagnostic and operative procedures (e.g., tumor resection, stone removal).

• Flexible Cystoscope: Bendable, more comfortable for awake patients, and used mainly for diagnostic exams in an office setting.

3. What procedures use a Rigid Cystoscope?

Common procedures include:

• Bladder tumor resection (TURBT)

• Removal of bladder stones

• Diagnosis of urinary tract abnormalities

• Urethral stricture management

• Foreign body retrieval

4. Is the procedure painful?

The procedure is performed under local, spinal, or general anesthesia to minimize discomfort. Patients may experience mild soreness afterward.

5. How should the Rigid Cystoscope be sterilized?

Rigid cystoscopes are reusable and must undergo high-level disinfection (HLD) or sterilization (autoclaving) following manufacturer guidelines to prevent infections.

6. What are the advantages of a Rigid Cystoscope?

• Superior optical clarity

• Stronger irrigation flow for better visibility

• More instrument channels for surgical procedures

• Longer lifespan compared to flexible scopes
