Percutaneous minimally invasive intra-abdominal gastrointestinal tract pushing and pressing device

Abstract

The invention relates to the technical field of medical instruments, and particularly discloses a percutaneous minimally invasive intra-abdominal gastrointestinal tract pushing and pressing device. The catheter comprises a catheter sheath, a soft catheter, a guide wire and a push rod, the catheter sheath and the push rod are of hard hollow structures, a circle of balloon is arranged at the end of the soft catheter, the balloon is connected with a channel, and the channel and the soft catheter are fixed together; the soft catheter can penetrate through the catheter sheath, the inner wall of the end, provided with the balloon, of the soft catheter is conical, and the push rod is arranged on the guide wire in a sleeving mode and then penetrates into the soft catheter. An exchange rod is further arranged, the guide wire can be inserted into the exchange rod, and the exchange rod can be inserted into the puncture needle. In the using process, gastrointestinal tracts can be effectively avoided, the gastrointestinal tracts are prevented from being punctured, and therefore potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a percutaneous minimally invasive intra-abdominal gastrointestinal tract pushing device. Background technique [0002] Due to the deep viscera lesions or deep tumor location in the abdominal cavity, if radioactive seed implantation therapy or biopsy is required, the needle needs to be punctured through the anterior abdomen, and the puncture path must pass through the gastrointestinal tract. To cause extra-intestinal and intra-abdominal infection, the puncture needle must avoid the gastrointestinal tract. At present, there is no relevant equipment or method to avoid the gastrointestinal tract, so there is a great safety hazard during the puncture process. SUMMARY OF THE INVENTION [0003] In order to make up for the defects of the prior art, the present invention provides a percutaneous minimally invasive intra-abdominal gastrointestinal tract pushing device which can su...

Problems solved by technology

[0002] Due to the deep abdominal visceral lesion or the deep location of the tumor, if implantation of radioactive seeds or biopsy is required, the needle needs to be punctured through the anterior abdomen, and the puncture route must pass through the gastrointestinal tract. To cause infection in the abdominal cavity outside the intestinal tract, the puncture needle must avoid the gastrointestinal tract. At present, there is no relevant equipment or method to avoid the gastrointestinal tract, so there is a great safety hazard in the puncture process
