Disposable Biopsy Forceps is a type of consumable commonly used in digestive endoscopic surgery. It is mainly used for accurate sampling of tissues in the digestive tract to assist pathological diagnosis. With its diverse design, safety and efficiency, it has become an important tool for the diagnosis and treatment of gastrointestinal diseases.
一. Structure and features: The structure of disposable biopsy forceps mainly consists of the following parts
Biopsy Cups: Usually made of stainless steel, the edges of the pliers are sharp, which can ensure accurate cutting of diseased tissues during sampling while reducing damage to surrounding healthy tissues. Some products have serrated edges, which are suitable for cutting hard tissues.
Shaft: There are various specifications in length and diameter, suitable for different models of endoscopes (such as gastroscopes and colonoscopes). Made of high-quality metal or high-strength composite materials, it ensures good flexibility and torsion resistance during operation.
Handle: Usually made of plastic, ergonomically designed, flexible and convenient to operate.
二. Disposable biopsy forceps are widely used in the following endoscopic diagnosis and treatment scenarios:
I. Tissue sampling for gastrointestinal diseases
1. Gastric diseases
* Chronic gastritis: Take tissue from the antrum or body of the stomach to detect the type of chronic gastritis, such as atrophic gastritis or intestinal metaplasia.
* Gastric ulcer: Take samples from the edge of the ulcer to determine whether there is Helicobacter pylori infection or malignant lesions.
* Gastric cancer screening: For suspicious lesions (such as ulcers, bulges or abnormal mucosa) found during gastroscopy, precise sampling is used for pathological diagnosis.
2. Esophageal diseases
* Esophagitis: Take samples to detect whether there is Barrett's esophagus or other inflammatory changes.
* Esophageal cancer: Take samples at suspected stenosis or abnormal hyperplasia to confirm the nature of cancer.
3. Small intestine and colon diseases
* Inflammatory bowel disease (IBD): For example, Crohn's disease and ulcerative colitis, biopsy is performed to assess the extent and type of inflammation.
* Polyps and adenomas: Polyps found by endoscopy usually require biopsy before resection to distinguish between benign and malignant lesions.
* Colorectal cancer screening: Abnormal thickening or bulging mucosa is sampled to assist in diagnosis.
II. Infectious disease testing
1. Helicobacter pylori testing
Mucosal tissue is taken from the gastric antrum and combined with rapid urease testing, tissue staining or molecular diagnostic technology to confirm Helicobacter pylori infection.
2. Special pathogen screening
In immunocompromised patients, fungal (such as Candida) or parasitic infections (such as Cryptosporidium) are detected by sampling with biopsy forceps.
III. Intraoperative auxiliary operation
1. Preoperative lesion assessment before polypectomy
- For large polyps found under endoscopy, biopsy forceps can be used to take samples in advance to assess whether they are suitable for endoscopic resection or require surgical intervention.
2. Endoscopic submucosal dissection (ESD) assistance
- During the ESD process, use biopsy forceps to mark the range of lesions and clarify the boundaries of the lesions to be removed.
3. Clear cause of esophageal or gastric stenosis
- Tissue biopsy is performed on the stenosis site to help determine whether it is inflammatory stenosis, tumor stenosis or postoperative scar stenosis.
IV. Postoperative follow-up and efficacy evaluation
1. Postoperative recurrence monitoring of cancer
- For abnormal mucosal hyperplasia found during postoperative review, use biopsy forceps to take samples to assess whether it is a recurrent lesion.
2. Chronic disease management
- For long-term follow-up of patients with chronic gastritis or ulcers, biopsy is used to understand the repair of lesion tissue and inflammation control.
V. Use in special scenarios
1. Foreign body detection
- When a suspected foreign body (such as a drug capsule or an incarcerated substance) is found in the esophagus or stomach, a small amount of tissue is clamped with a biopsy forceps to analyze its properties.
2. Intraoperative hemostasis
- Although the main function is sampling, some types of biopsy forceps can temporarily stop bleeding through the clamping action when there is slight bleeding, buying time for the next step.
3. Tissue culture sampling
- In patients with unexplained chronic gastrointestinal symptoms, mucosal tissue is obtained through biopsy for bacterial culture or molecular testing (such as PCR).
三. Future development direction
With the continuous advancement of technology, the design and performance of disposable biopsy forceps are also continuously optimized. Possible future development directions include:
More refined specification design
To meet the needs of minimally invasive and difficult surgery, develop biopsy forceps with smaller diameters and longer pipes.
Intelligent function
Integrate sensors or cameras on the forceps head to achieve precise navigation of the sampling position.
Environmentally friendly material application
Use biodegradable or recyclable materials to reduce the impact of medical waste on the environment.
Combined design
Combining biopsy forceps with other endoscopic consumables (such as injection needles or resection knives) to enhance the versatility of surgical instruments.
