Abstract

The invention discloses a seal cartridge and a puncture outfit with the same. The seal cartridge comprises a seal body and an assembly flange, wherein the seal body comprises a seal cylinder and a plurality of seal valves; the seal cylinder is arranged in penetrating manner, and is provided with an upper opening and a lower opening; the upper end of an arbitrary seal valve is smoothly connected with the edge of the lower opening of the seal cylinder; the lower end edges of the plurality of seal valves are supported against one another; the lower opening of the seal cylinder is optionally opened or closed; each seal valve is provided with a top surface and a bottom surface opposite to the top surface, the top of each seal valve is arranged toward the upper opening of the seal cylinder, and the bottom of each seal valve is a concave curved surface; and the assembly flange is positioned on the outer surface of the seal cylinder. According to the seal cartridge, the seal valves are optimized, so that the seal cartridge can be well closed when a puncture core pin is pulled out, the sealing property of a passage formed by a puncture sleeve can be effectively guaranteed, and occurrence gas leakage can be avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a sealing sleeve and a trocar with the sealing sleeve. Background technique [0002] In abdominal examination, abdominal surgery and other minimally invasive or surgical operations, trocar is an indispensable surgical instrument. The puncture device can establish an access channel in the abdominal wall of the human body, so that the laparoscope or other surgical instruments (such as endoscopes, scissors, staplers, guide wires, catheters, filters, stents, etc.) Channels to control the pneumoperitoneum required for surgery for examination or surgical manipulation. At the beginning of a minimally invasive laparoscopic medical operation, the doctor generally makes a small incision in the patient's abdomen, and then aligns the apex of the puncture end with the small incision and moves it downward while reciprocating left and right. through the patient's abdominal cortex. After the ...
