Description

Electric anastomat

Technical Field

The utility model relates to the field of medical instruments, in particular to an electric anastomat.

Background

Staplers are commonly used instruments in surgical procedures, such as laparoscopic staplers used in laparoscopic procedures. The electric anastomat is powered by a battery pack, and is driven by a motor to push the cutting knife and the wedge-shaped pushing block to advance so as to realize tissue anastomosis and cutting functions. After the anastomat is completely fired, the nail bin can be disassembled, and a new nail bin is replaced for continuous use.

In view of the strict requirements of surgical operations on sterility, the current electric anastomat and the battery pack thereof can only be used in a single operation, and once the operation is finished, the electric anastomat and the battery pack can be discarded, so that not only is great waste caused, but also toxic and harmful substances contained in the battery pack can cause great damage to the environment. If the battery pack can be reused, the environmental pollution risk is greatly reduced, the cost of single operation consumable materials is reduced, and the economic pressure of patients and medical insurance is reduced.

To achieve battery pack reuse, a sterile barrier needs to be established first. Surgical procedures require that the instruments used be sterilized in areas where doctors and patients are accessible, and that they be free of contamination from areas of bacteria during unpacking, assembly and use. The battery pack cannot be subjected to conventional sterilization (usually high-temperature steam sterilization) in a hospital due to the characteristics of an internal battery, if the battery pack is recycled by a manufacturer to be subjected to special process sterilization, the process is complex, the period is long, the battery pack needs to be subjected to secondary packaging after sterilization, the battery pack is extremely inconvenient to recycle, manage and use, and meanwhile, the cost is high, so that the battery pack cannot be lost.
