Electric anastomat with detachable power module and power module shell

Abstract

The invention provides an electric anastomat with a detachable power module and a power module shell, the electric anastomat comprises a main body, wherein the main body can cut tissue and trigger an anastomosis nail to close a wound surface for hemostasis, and the main body is provided with an interface board; the power module which can be detachably connected to the main body, wherein the power module comprises a control unit, the power module further comprises a motor and / or a battery assembly, and when the main body and the power module are connected together, the control unit is electrically connected with the interface board. By adopting the technical scheme, at least one of the control unit, the motor and the battery of the electric anastomat can be detached from the main body, and the detached part can be repeatedly used by being disinfected or replacing a disposable sterile power module shell so that the use cost of the electric anastomat is reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an intelligent electric-driven surgical instrument, especially an intelligent electric stapler. Background technique [0002] The electric stapler is used in minimally invasive surgery, which can cut the diseased tissue and close the wound. In the prior art, electric staplers are all used for one-time use, resulting in higher cost of use and heavy burden on patients. The power source of the existing electric stapler is mainly the motor. Since the stapler is disposable, due to cost considerations, the quality of the selected motor is poor, resulting in a high risk of failure of the electric stapler. [0003] Because the electric stapler is driven by a motor, it cannot perceive the force used when cutting tissue and closing the tissue wound, and cannot judge the thickness of the tissue or even the tissue lesion. [0004] Depending on the actual situation, the electric stapler n...

In the prior art, electric staplers are all disposable, resulting in high cost of use and heavy burden on patients

The power source of the existing electric stapler is mainly the motor. Since the stapler is a one-time use, due to cost considerations, the quality of the selected motor is poor, resulting in a high risk of failure of the electric stapler.

[0003] Because the electric stapler is driven by a motor, it cannot sense the force used when cutting tissue and closing the tissue wound, so it cannot judge the thickness of the tissue or even the state of tissue lesions.

[0004] Depending on the actual situation, the electric stapler needs to have staple cartridges of different lengths, and the movement stroke of the firing rod is also different for staple cartridges of different lengths. The existing electric staplers are used with staple cartridges of a specific length and cannot be replaced. Staple cartridges of different lengths
