Puncture device for abdominal surgery

Abstract

The invention discloses a puncture device for abdominal surgery. The device includes a vertical plate, a puncture needle drive unit, a needle cylinder fixing unit, a lifting unit and a fixing unit; the vertical plate is rotatably connected with a needle cylinder through a rotating shaft, the interior of the needle cylinder is connected with a puncture needle, the bottom end of the needle cylinderis provided with a liquid pumping hole, the liquid pumping hole communicates with a small water pump through an infusion hose, the small water pump is located on the side of the top end of the needlecylinder, a liquid outlet of the small water pump is connected to an external collection bag through a hose, an installation cylinder is installed at the rear side of the vertical plate, and the installation cylinder is connected with a Z-shaped rod; and the puncture needle driving unit includes a driving gear, a driven gear, a second servo motor, a thread rod, a nut and a cylinder. The puncture device for the abdominal surgery provided by the invention accurately locates a puncture position, can stably and safely perform abdominal wall puncture on a patient, and is not easy to cause injury tothe patient.

Description

technical field [0001] The invention relates to the technical field of abdominal surgery, in particular to a puncture device for abdominal surgery. Background technique [0002] The abdominal cavity is the cavity between the pelvic cavity and the diaphragm, which mainly plays a role in digestion and absorption. When the human body is cirrhotic, it is very easy to cause hydroperitoneal. A small amount of hydroperitoneal usually does not cause symptoms, but a large amount of hydroperitoneal Ascites can cause abdominal distension and discomfort, and shortness of breath. In some patients with ascites, the joints are swollen due to excessive water. In severe cases of ascites, a puncture of the abdominal wall is required to extract a small amount of ascites samples to determine the cause of the ascites. Usually the collection of ascites is done manually, using a syringe with a puncture needle and a through hole at the bottom to puncture the patient's abdominal wall, and use a hose...

In severe cases of ascites, a puncture of the abdominal wall is required to extract a small amount of ascites samples to determine the cause of the ascites. Usually the collection of ascites is done manually, using a syringe with a puncture needle and a through hole at the bottom to puncture the patient's abdominal wall, and use a hose to extract ascites. However, manual paracentesis is very easy to damage In the tissue near the abdominal cavity, the positioning of the puncture position is inaccurate, which is likely to cause secondary injury to the patient, and when the ascites is extracted, the puncture needle is built into the abdominal cavity, and a slight vibration may cause injury to the patient
