Abstract

The invention relates to the technical field of medical instruments, and discloses an abdominal cavity puncture stitching instrument which comprises a puncture tube sheath and a stitching assembly, the puncture tube sheath is in a hollow sleeve shape, and the stitching assembly is rotatably buried in the side wall of the puncture tube sheath. Further, the suturing assembly comprises at least two puncture needle tubes and two puncture needles, an axial needle tube channel is arranged between the inner wall and the outer wall of the puncture tube sheath, the two puncture needle tubes are symmetrically arranged in the needle tube channel, the upper ends of the puncture needle tubes upwards penetrate out of the needle tube channel to be connected with a handle, and the lower ends of the puncture needle tubes upwards penetrate out of the needle tube channel to be connected with the handle. The lower end of the puncture needle tube penetrates out of the needle tube channel to be connected with a needle arm, the needle arm is in an arc shape coaxial with the puncture tube sheath, the other end of the needle arm is connected with a puncture needle, and the puncture needle is axially parallel to the puncture tube sheath. The device integrates the functions of puncturing and suturing, is ingenious and simple in structure, sutures from inside to outside, and is safer and firmer in suturing; when the puncture tube sheath is pulled out, suture of a puncture hole is completed, trauma is small, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an abdominal puncture stapler. Background technique [0002] Laparoscopic surgery is a minimally invasive surgical method. It has been widely used because of its small trauma and quick recovery. Many open operations in the past have been replaced by laparoscopic surgery. Laparoscopic surgery must establish a working channel on the abdominal wall through a paracentesis, and then use special lengthened surgical instruments to complete the operation under the laparoscopic display screen. At present, the size of the puncture device is 5mm-15mm in diameter, and the puncture hole is small. It is difficult to suture the puncture site after surgery, which may lead to the risk of incisional hernia in the postoperative incision. [0003] Chinese invention patent application CN108542450A discloses a laparoscopic puncture stapler, including an outer sleeve, a puncture device, an...
