Abstract

The invention discloses a puncture tube assembly containing a rotary bolt, comprising a hollow tube assembly and a sealing assembly, the proximal end of the hollow tube assembly is connected with the distal end of the sealing assembly to form an airtight seal for a puncture device a hollow tube assembly comprising an outer tube, an inner tube and a swivel; the outer tube includes an outer tube proximal end and an outer tube distal end and an outer tube wall extending therebetween, the outer tube wall defining a first hollow passage The outer pipe also includes an axial tunnel arranged along its axial direction, the tunnel includes a first tunnel side wall and a second tunnel side wall integrated with the outer pipe wall and a tunnel top wall connected thereto, The tunnel includes a tunnel passage communicating with the first hollow passage; the inner pipe includes a proximal end of the inner pipe and a distal end of the inner pipe and an inner pipe wall extending therebetween, and the outer surface of the inner pipe wall includes an outer cylindrical surface of the inner pipe, The outer surface of the proximal end of the inner tube includes an outer bump.

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to a puncture tube assembly containing a rotary bolt. Background technique [0002] A trocar is a surgical instrument used to establish an artificial channel into a body cavity in minimally invasive surgery (especially hard tube endoscopic surgery). Usually consists of a puncture tube assembly and a puncture needle. Its general clinical use method is: first cut a small opening on the patient's skin, then pass the puncture needle through the puncture tube assembly, and then penetrate the abdominal wall through the skin opening and enter the body cavity together. Once in the body cavity, the needle is removed, leaving the puncture tube assembly as a passage for the instrument to enter and exit the body cavity. [0003] In rigid endoscopic surgery, an insufflation machine is usually used to continuously perfuse gas (such as carbon dioxide gas) into the patient's abdominal c...
