The utility model discloses a kind of anti-infiltration devices for abdominal cavity drainage tube, it is related to medical auxiliary appliance technical field, when using conventional drainage tube, because the suture gap exists between the smaller drainage tube diameter and abdominal wall puncture hole, postoperative ascites is easily leaked outside through the gap inserted by drainage tube, increase the risk of infection and off pipe, and wound exudate is alkaline, continuous skin irritation aggravates patient's pain, delay healing time, increase patient's medical cost.The utility model provides a kind of anti-infiltration device for abdominal cavity drainage tube, including drainage tube, annular groove is arranged on the drainage tube, negative pressure disc is arranged on the annular groove, the negative pressure disc is slidably connected with drainage tube, expansion air bag capable of extruding negative pressure disc is also arranged on the annular groove, fixed air bag is also arranged on the drainage tube, the fixed air bag is arranged at one side of annular groove, and expansion air bag is respectively arranged at both sides of negative pressure disc, can avoid drainage tube off pipe, avoid exudate leakage.

The trocar assembly comprises a head, a long tubular structure having an open distal end and an open proximal end, a fixed cutting component combining a large cutter with two sharp lateral blades and a centrally located non-cutting soft end extending through the open distal end of the tubular structure, and a movable cutter safety case configured to extend through the open distal end of the tubular structure to cover the fixed cutting component and to retract from the open distal end to expose the fixed cutting component. When pressure is applied proximal to the cutter safety case, a large incision is formed in the fascia, the abdominal wall is penetrated, the reaction pressure from the abdominal wall is released, and the body cavity is safely reached.

The present application can easily perform installation of a puncture needle guide adapter to an ultrasonic probe outside the abdominal cavity, and can easily confirm the installation state of the puncture needle guide adapter inside the abdominal cavity. Alternatively, insertion and extraction of the ultrasonic probe from a guide tube that passes through the abdominal wall can be smoothly performed. A puncture adapter (400) is detachably installed to a head (210) of a probe (200) outside the abdominal cavity. The puncture adapter (400) has a main body portion that covers a through hole for guiding a puncture needle, an insertion portion that is inserted into the through hole, and a needle guide hole that communicates with the main body portion and the insertion portion and guides the puncture needle inserted from a needle inlet portion of the main body portion to a needle inlet portion of the insertion portion.

This utility model proposes a trocar for laparoscopic surgery, relating to the field of trocar technology. It includes a trocar cone and a trocar cannula assembly. The trocar cone penetrates the trocar cannula assembly. The trocar cannula assembly includes a ventilation connector and a positioning cannula. One end of the positioning cannula is fixedly connected to and communicates with one end of the ventilation connector. The other end of the ventilation connector is detachably connected to the trocar cone. The other end of the positioning cannula is provided with an inflation-expansion blocking part, which communicates with the positioning cannula. This trocar for laparoscopic surgery can flexibly block the abdominal wall, effectively improving the airtightness of the trocar cannula fixed to the patient's abdominal wall.

This model helps in understanding the gross anatomy (shape, relative size, and three-dimensional positional relationship) of the intestines and mesentery. It is useful for medical students and young healthcare professionals to acquire basic knowledge for understanding the pathophysiology of diseases and injuries of abdominal organs, as well as for examination and treatment. [Solution] The model 50 has an intestinal tract 2 covered and embedded by the peritoneum 1, an intestinal tract 2 provided in the posterior abdominal wall 4 in a form where much of the outer circumference is covered by the peritoneum 1, and an intestinal tract 2 provided in the posterior abdominal wall 4 via the mesentery 5, wherein each of the intestinal tracts 2 is made of a flexible and smooth pliable material and attached to a substrate 23 which is the posterior abdominal wall 4, and each of the intestinal tracts 2 and the mesentery 5 are configured to be the same as or approximately the same length and thickness as those in living organisms, thereby solving the above problem.

This utility model relates to an intestinal decompression tube for insertion into an abdominal wall stoma, comprising a tube body and a main cavity in the middle of the tube body. A drainage interface connected to the main cavity is provided at the top of the tube body. A posterior balloon interface, a ventilation tube interface, and an anterior balloon interface are sequentially provided on the drainage interface. A guidewire channel connected to the ventilation tube interface is provided inside the tube body, and a guidewire is placed within the guidewire channel. A posterior balloon and an anterior balloon connected to the posterior and anterior balloon interfaces are respectively provided on the tube body. Several first side holes for suctioning and flushing thick feces are provided between the posterior and anterior balloons. Several steel balls are provided on the inner wall of the bottom end of the tube body. The posterior and anterior balloons are used to fix the tube body, the guidewire is used to pass through intestinal stenosis, and the steel balls are used for the tube body to turn, facilitating passage through intestinal stenosis. This design offers wide applicability.
