Gas jet fluid removing device and method in a trocar

Devices and methods are provided for removing fluid from a surgical access device and / or from surgical instruments passed therethrough, and for preventing such fluid from accumulating. For example, in one embodiment, an exemplary device can include a body defining a working channel that is configured and sized to allow for passage of a surgical instrument therethrough. A number of seals can be disposed in the working channel so as to contact the inserted surgical instrument. One or more outlets can be oriented to direct gas, such as air or an insufflation gas, into the working channel so as to remove fluid on the seals, or other parts of the surgical access device, as well as the surgical instruments themselves. In some embodiments, constant flows of gases can be arranged to act as shields to help prevent fluid from accumulating on the surgical access device and / or surgical instruments.

Safety trocar device

A safety trocar device designed for safe abdominal endoscope operation, including a trocar assembly and a bracket. The trocar assembly includes a sleeve, a trocar and an insufflation needle. A bottom end of the trocar assembly has a thrust section. In use, the trocar assembly is mounted on a suspension arm of the bracket and the bracket is fixed on an operation table. The bracket has an elevation arm under the suspension arm for hooking the abdominal wall of a patient. In operation, an operator continuously turns the trocar assembly with one hand and the abdominal wall is gradually elevated by the elevation arm, whereby the thrust section penetrates through the abdominal wall. Accordingly, the trocar assembly will only drill through the elevated abdominal wall without touching the organs in the abdominal cavity. The trocar assembly is provided with penetration indicator for the operator to judge whether the trocar assembly has truly penetrated through the abdominal wall.
