Electric intelligent surgical anastomat

Abstract

An electric intelligent surgical anastomat comprises an electric intelligent drive component and a replaceable suture execution component, the electric intelligent drive component is arranged in a gun type outer shell, a power supply switch, a nail abutting seat opening switch and a nail abutting seat closing switch are arranged on the outer shell, and a master control circuit board, a gearbox, a nail abutting seat opening / closing motor and a percussion motor are arranged in the outer shell. Surgical suturing instruments and other products of the same series are automatically and intelligently controlled, compared with the existing mechanical surgical suturing instruments, the electric intelligent surgical anastomat is more convenient to operate, doctors can operate the anastomat and complete operations without learning, precise control of tissue pressure and suture nail forming is adopted, bleeding and leakage due to the fact that the mechanical surgical suturing instruments are used improperly are effectively prevented from happening to an anastomotic stoma, and the operational quality of the mechanical surgical suturing instruments is improved. Operation quality and safety is improved, and the operation of users is more convenient.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an electric intelligent stapler for surgery. Background technique [0002] Medical surgical stapler is a surgical instrument commonly used in gastrointestinal surgery and lung surgery in chest, abdomen, anorectal and other fields. The requirements of surgical anastomosis for the anastomosis are no bleeding and no leakage, and at the same time, the blood supply to the anastomosis and the distal tissues can be guaranteed. The stapler places the tissue between the staple cartridge and the anvil, and compresses the tissue by adjusting the distance between the staple cartridge and the anvil, when the distance between the staple cartridge and the anvil reaches the safe range for effective suturing When fired, the U-shaped staples are compressed into a B-shape to suture the tissue, and small blood vessels can pass through the gaps of the B-shaped staples to ensure the blood supply of...

AI Technical Summary

Problems solved by technology

There are three types of tissue compression caused by this operation: insufficient compression (leading to anastomotic bleeding and leakage); moderate compression (moderate compression force and compression time make the liquid in the tissue be discharged, the best tissue anastomosis conditions); excessive Compression of (causes tissue damage)

Similarly, the formation of staples will also appear in three states: insufficient formation, moderate formation, and excessive formation. These are the reasons for the failure of the operation

However, the mechanical stapler does not provide any method and device that can control the tissue compression force, and lacks a device for precise control during the operation, so this mechanical structure may reduce the quality of the operation or lead to the failure of the operation

In addition, the mechanical stapler does not have accurate status information feedback. The user relies entirely on experience to use the instrument, and the operation process is carried out without visualization. This also easily leads to misjudgment by the user, and the mechanical stapler cannot provide suture result information. , so that the user does not know the final use effect after the operation, and it is difficult to form a reasonable accumulation of experience
