Abstract

The invention discloses a core-less puncture outfit, comprising a puncture point, a thimble assembly and a seal assembly, wherein the thimble assembly comprises a thimble arranged in a penetrating manner, one end of the thimble is selectively sealed by the seal assembly, the other end of the thimble is accommodated in the puncture point and selectively opened or closed by the puncture point, and the puncture point can be connected to the outside wall surface of the other end of the thimble. The core-less puncture outfit disclosed by the invention is convenient in use and low in cost, the core-less puncture outfit is not provided with a puncture core bar as the traditional puncture outfit, puncture of the puncture outfit is realized by the puncture point, and when an anastomat or other operative instruments need to enter an abdominal cavity, the port of the thimble is opened for the anastomat or other operative instruments to enter.

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] In abdominal examination, abdominal surgery and other minimally invasive or surgical operations, trocar is an indispensable surgical instrument. The trocar can establish an access channel in the abdominal wall of the human body so that staplers or other surgical instruments (such as endoscopes, scissors, guide wires, catheters, filters, stents, etc.) To control the pneumoperitoneum required for surgery for examination or surgical manipulation. [0003] At the beginning of the minimally invasive stapler medical operation, the doctor generally makes a small incision in the patient's abdomen, and then aligns the apex of the puncture end of the puncture mandrel with the small incision and moves it downward while reciprocating left and right. The puncture sleeve passes through the cortex of t...
