Abstract

The invention discloses a puncture body component. The puncture body component comprises a puncture member and a protective casing. The puncture member comprises a puncture tip. The protective casingis made from an elastic material. When the puncture body component is in an initial state, the protective casing covers the puncture tip; the protective casing can elastically deform or restore to aninitial state to allow the puncture tip to be exposed from the bottom of the protective casing or covered by the protective casing. The puncture body component applied to a coreless puncture device isconvenient to use; both the production cost of the whole puncture device and the packaging cost of the puncture device can be saved; due to the design of the puncture body component, the operationalsafety in coreless puncture is integrally improved.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a puncture body assembly, 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 pati...
