Electric anastomat capable of detecting percussion resistance

Abstract

The invention provides an electric anastomat capable of detecting percussion resistance, the electric anastomat comprises a percussion mechanism, wherein the percussion mechanism comprises a screw rod, a screw rod sleeve and a percussion rod, the percussion rod is connected to the screw rod sleeve, the screw rod is sleeved with the screw rod sleeve, the screw rod sleeve can be driven to move in the front-back direction through rotation of the screw rod, and thus the percussion rod moves in the front-back direction along with the screw rod sleeve; and a pressure sensor which is located at the rear end of the percussion rod, wherein when the percussion rod is subjected to resistance during forward movement, the percussion rod transmits force to the pressure sensor. By the adoption of the technical scheme, the pressure sensor is arranged at the rear end of the percussion rod, so that the resistance borne by the electric anastomat during percussion is detected, the thickness of tissue can be judged through the resistance, and a doctor can judge the lesion condition of the tissue.

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
