Abstract

The invention discloses a coreless puncture device, which comprises a sleeve assembly and a puncture body assembly, the puncture body assembly includes a puncture piece and a protective shell, the puncture piece includes a puncture tip, the puncture piece is fixedly arranged on the sleeve assembly, the protection shell and the sleeve The tube assembly is a sliding connection, and the piercing tip can be selectively exposed from the bottom of the protective case. The coreless puncture device in the present invention is easy to use, which not only saves the preparation cost of the entire puncture device, but also saves the packaging cost of the puncture device. At the same time, the design of the puncture body assembly also improves the operation safety of the coreless puncture device in the present invention as a whole .

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a coreless puncturer, which belongs to the field of medical equipment. Background technique [0002] Trocar, as an indispensable surgical instrument in various minimally invasive surgeries, has a very large amount of use. A traditional trocar includes a puncture mandrel, a puncture sleeve, and a sealing assembly. The puncture sleeve and the sealing assembly together form a channel for the puncture mandrel, other surgical instruments, and gas infusion to the patient's peritoneal cavity; the sealing assembly is arranged in the puncture sleeve for Avoid leakage of the gas injected into the abdominal cavity and ensure a stable pneumoperitoneum so that the operation can be carried out normally. The puncture mandrel is inserted into the puncture cannula through the sealing assembly to puncture the patient's abdominal cavity and drive one end of the puncture cannula into the Inside the patient'...
