In diagnosing diseases, to accurately determine the cause, a biopsy of the lesion is required. The doctor uses medical instruments to obtain a certain amount of living tissue from the lesion for pathological analysis to facilitate targeted treatment.
Previously, the common instrument was a spring-loaded biopsy needle, which operates by releasing an internal spring to perform the biopsy within the lesion. During use, guided by ultrasound, CT, etc., the biopsy needle is punctured into the lesion, then the spring is released, allowing the needle to quickly puncture the lesion. If tissue is not obtained in one attempt, the procedure is repeated, increasing the risk of damage; additionally, since the force is provided by the spring, it is challenging to control the depth of the biopsy needle.
This calls for a more convenient and straightforward endoscopic specimen extraction device, hence the invention of the endobag.
An endobag is a medical device specifically designed for minimally invasive surgeries, playing a crucial role in laparoscopic operations. The primary function of the endobag is to collect tissue specimens or foreign objects within the body during minimally invasive endoscopic procedures and safely remove them. These collected tissues or foreign objects may include the appendix, gallbladder, ovaries, fibroids, and various other tissues and stones. The endobag is designed to simplify the surgical process, enhance surgical efficiency, and ensure patient safety and recovery.
The endobag is mainly used in laparoscopic surgeries in general surgery, hepatobiliary surgery, pancreatic surgery, gastrointestinal surgery, urology, and gynecology. It serves as an accessory product to laparoscopic instruments during abdominal surgeries for removing biopsy samples from the surgical site, facilitating specimen isolation, and avoiding infection of other tissues.
In general surgery, the endobag is often used to collect and remove tumors, cysts, or other abnormal tissues within the body.
In hepatobiliary surgeries such as cholecystectomy or partial hepatectomy, the endobag can conveniently collect and remove the gallbladder, stones, or other liver tissues.
Pancreatic surgeries often involve complex anatomical structures, and the endobag can safely collect pancreatic tissues, cysts, or tumors, avoiding contamination and infection during the procedure.
In gastrointestinal surgeries, the endobag is frequently used to collect diseased tissues from the stomach, intestines, and other parts of the digestive system, ensuring the smooth progress of the surgery.
In urological surgeries, such as nephrectomy or bladder surgery, the endobag can conveniently collect kidney, bladder, or other urological tissue specimens.
In gynecological laparoscopic surgeries, the endobag is often used to collect specimens from the ovaries, uterine fibroids, uterus, or other gynecological tissues.
