AI Technical Summary

Technical Problem

The smoke exhaust system of the existing single-hole multi-channel laparoscopic protector is inefficient, resulting in unclear vision of the surgical field, affecting the smooth progress of the operation and the safety of the patient.

Method used

A smoke exhaust device including an external smoke exhaust pipe and an inner tube is designed. The smoke exhaust inner tube can be bent and molded, and a smoke exhaust hole is provided directly above the surgical area to inhale the smoke generated by the surgery more effectively, while adding a protective cap to the end of the smoke exhaust pipe to reduce the damage to the peritoneum by negative pressure.

Benefits of technology

It improves smoke exhaust efficiency, reduces the impact of smoke on the visual field during surgery, shortens the operation time, reduces the risk of surgery, and increases the safety of surgery.

Abstract

The utility model relates to the technical field of medical instruments, in particular to a single-hole multi-channel laparoscope protector smoke exhaust device which comprises a smoke exhaust pipe, the smoke exhaust pipe comprises a smoke exhaust outer pipe and a smoke exhaust inner pipe, the smoke exhaust outer pipe is arranged outside a protector platform, the smoke exhaust inner pipe is arranged in the protector platform, and the smoke exhaust outer pipe is arranged in the protector platform. The smoke exhaust outer pipe is communicated with the smoke exhaust inner pipe or the smoke exhaust outer pipe and the smoke exhaust inner pipe are integrally formed, the smoke exhaust inner pipe can be formed in a bent mode, the position of the smoke exhaust hole is transferred to the position over an operation area from the position under the single-hole protector, the single-hole protector is more suitable for inhalation of upwards-jetted smoke generated by an energy instrument in an operation, and the smoke exhaust effect is better. Therefore, the smoke exhaust efficiency is improved. The influence of smoke on the operation view of a doctor during operation is reduced, the operation efficiency is improved, the operation safety is improved, and a safer operation process is also brought to a patient.
