Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an integrated laparoscopic amputation and suturing fixing forceps. Background Art

[0002] Currently, in pyeloureteroplasty, in order to ensure the stable implementation of the operation, the renal pelvis and ureter need to be separated separately, and a vascular clamp is used to hang them in the abdominal cavity with wire traction, and sutured in the air. The operation is difficult and the tension after traction is large, which is not conducive to the alignment and suturing of the renal pelvis and ureter.

[0003] Unlike open surgery, laparoscopic division and suturing need to be performed in mid-air. Since there are no dedicated division, suturing and fixation instruments, the doctor's operational level is required to be high, and operational errors are prone to occur during the operation, such as inappropriate hanging position, suturing angle, inappropriate reserved length, etc.

[0004] It can be seen that the existing medical devices have the defects of inconvenient operation of laparoscopic suturing and fixation devices and high requirements for doctors. The defects of the existing fixation devices used for laparoscopic suturing are: 1. Application document CN111110320A discloses an organ support and fixation device for minimally invasive abdominal surgery. However, during the use of the fixation device, the length of the organ after the cut and resection may not be suitable for suturing; 2. In the traditional surgery, the ureteroplasty is performed by manual clamping and suturing in the abdominal cavity, which is difficult for doctors to operate. 3.
