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.

A seat belt buckle for seat belts has a housing, an opening for inserting a seat belt tongue, a locking device for locking the seat belt tongue, and a release device for releasing the seat belt tongue from the lock. A sensor device electrically senses whether the seat belt tongue is locked, wherein the sensor device has a switch arrangement which can be activated by the seat belt tongue. The switch arrangement has an electrically conductive snap-action plate that can be moved between a first switched position and a second switched position. A mechanical activation device transmits a force exerted on the seat belt tongue during the insertion of the seat belt tongue onto the snap-action plate in order to move the snap-action plate from the first switched position into the second switched position. As a result, an electrical contact element is closed or opened.

The invention provides a triad trocar device for deep tissue puncture. The triad trocar device comprises a thick puncture needle, a puncture cannula and a fine puncture needle; in the puncture process, when shallow tissue is punctured, the tips of the thick puncture needle, the puncture cannula and the fine puncture needle are aligned; when deep tissue is punctured, the puncture cannula and the fine puncture needle extend out of the first end of the thick puncture needle and pierce into the deep tissue together, then the fine puncture needle is withdrawn, and a channel is established between the deep tissue and the exterior of the body of a subject through the puncture cannula. By means of the puncturing device and method, important tissue organ damage can be reduced when the deep tissue is punctured, the sensitivity of the deep tissue during puncturing is increased, and the success rate of puncturing is improved, so that clinical prognosis is improved, and the device and method can beapplied to clinical practice such as pericardial effusion puncture drainage and subclavicular vein puncture catheterization, and have high clinical application value.

The invention relates to a trocar sleeve or trocar and a trocar tip for minimally invasive/endoscopic surgical procedures carried out on people or animals. The trocar sleeve here has holding means in order to prevent the device from slipping out during the operation.

The invention relates to a clamping mechanism for a trocar device. A mounting cavity of the trocar device is connected with a trocar mounting rack connected on a sliding table, a positioning block isarranged on the mounting cavity, a positioning groove is arranged in the trocar mounting rack, and through the embedding of the positioning block and the positioning groove, the locating and fixing during clamping of the trocar device with the trocar mounting rack is carried out; and a buckle is arranged on one side of the trocar mounting rack, a convex edge is arranged on one side of the mountingcavity, and the tight clamping of the trocar device with the trocar mounting rack is carried out through the clamping between the buckle and the convex edge. The clamping mechanism is simple in structure, and the trocar device and the trocar mounting rack can be conveniently and rapidly assembled and disassembled. The clamping mechanism is easy to operate, and stable and reliable in structure.

The invention relates to a trocar device, relates to the field of medical apparatus and instruments, and in particular relates to a trocar device used for a laparoscopic surgery robot, used for solving the technical problem that for the trocar device in the endoscopic surgery in the prior art, the insertion position is not accurate, the depth is inconsistent, thus the surgery quality is reduced, and the surgery demands can not be satisfied. The trocar device provided by the invention comprises marking lines which are arranged on the outer side of the tube wall of the trocar device. For the trocar device, the depths inserted into the skin are consistent, thus the accurate setting of the insertion position of the trocar device each time is realized, and the surgery demands are satisfied.
