Description
Technical Field
The utility model relates to the field of medical equipment, in particular to a blood clot removing device.
Background
The Endoscopic Retrograde Cholangiopancreatography (ERCP) technique is used as an endoscopic invasive operation technique, becomes a gold standard in diagnosis and treatment of biliary and pancreatic diseases, and has incomparable advantages in treating common diseases such as obstructive jaundice and common bile duct stones. The endoscopic duodenal large papilla intubation is a key step of success or failure of the ERCP technology, a cutting knife and a guide wire with a hydrophilic head end are placed through an endoscopic forceps channel, and an operating doctor is used for intubating the guide wire into the common bile duct in the 11 o' clock direction of the papilla opening by observing the papilla structure.
The technology of the intraduodenal large papillary intubation under the endoscope has a certain failure rate, when the intubate is tried repeatedly, the intubate can not enter the bile duct or even enter the pancreatic duct, the intubate can be defined as a difficult intubate, a doctor can further adopt the method similar to nipple pre-incision, or after the intubate enters the pancreatic duct, a guide wire can be reserved, and the bile and pancreas compartment can be incised towards the pancreatic duct direction, so that the bile duct opening is exposed, and the intubate of the bile duct is convenient. All of the above procedures involve sphincterotomy, with some arterial blood supply around the duodenal papilla, and invasive incision procedures can easily lead to bleeding in the papilla area, even fatal active bleeding. Once the blood seeps into the operation area, blood clots are easy to form and cover the surface of the nipple opening, the existing treatment measures are to carry out pressurized flushing on the saline in the injector under the endoscope forceps channel, the method is difficult to accurately position the blood clots, the flushing effect is rough, the effect of flushing the blood clots from the nipple surface is often not achieved, the operation visual field of doctors is affected, the intubation time is prolonged, the intubation is blindly tried, and the risk of pancreatitis after ERCP operation is easily increased.
Summarizing the current clinical shortcomings of treatment modalities that affect physician operation against a nipple bleed clot are mainly:
1. normal saline washes unable accurate location blood clot position, leads to the doctor to need try repeatedly, and the effect is comparatively extensive, leads to extension and the field of vision of intubate time to be unclear easily, blind intubate under the invisible condition of bile duct opening, further increases the risk of postoperative pancreatitis.
2. The existing endoscopic consumable material passing through the endoscopic forceps channel is not directly contacted and wiped to an operation area, the only expansion saccule has a certain effect of inflating and compressing the nipple to stop bleeding when the nipple is actively bleeding, however, the expansion saccule is complex in design, the reserved guide wire is not matched with an assistant well during rapid exchange to be easily taken out of the bile duct, so that re-intubation is needed, the use of the saccule needs to be established on the basis that the guide wire is reserved in the bile duct, the guide wire is not added into the bile duct or the intubation does not enter the bile duct, the use of the saccule is limited, and the consumable material is expensive.
