Description

Technical Field

[0001] The utility model relates to the field of medical auxiliary equipment, in particular to an auxiliary device for anastomosis apparatus. Background Art

[0002] During laparoscopic and / or endoscopic surgery, the procedure is performed through a small incision or a narrow cannula inserted into the wound. In traditional or open procedures, the doctor directly contacts the surgical site. Laparoscopic surgery has advantages over open surgery due to reduced patient trauma, shortened patient recovery period and significantly reduced overall costs; in order to meet the specific needs of endoscopic and laparoscopic surgery, endoscopic suturing devices have been developed to allow doctors to access the surgical site more easily. Staplers are commonly used suturing devices in medicine. The main working principle is to use titanium nails to sever or staple tissues. Suturing with titanium nails or stainless steel nails (skin staplers) makes the wound on the patient's body smaller, so the patient has fewer side effects and is more conducive to avoiding complications. When using the stapler, the stapler assembly needs to be installed and disassembled by medical staff. If the medical staff installs or disassembles the stapler assembly by hand, it is not only inefficient but also there is a risk of injuring the medical staff's fingers, which poses a serious hidden danger to the medical staff in treating patients. Moreover, during the use of the stapler, the jaws clamp too thick tissue or foreign objects, causing the instrument to lose power. When the electric power cannot be reset, it is necessary to manually move the manual joystick on the instrument, which has a large resistance and is difficult to operate.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content
