In recent years, the minimally invasive laparoscopic surgery is rapidly developed, and the introduction of the traditional multi-instrument from 3-4 holes by using a card (thocar) is improved into the introduction of the one-hole multi-instrument. The operation type puncture outfit is characterized in that a small incision is formed in the umbilical region of a patient, a single-hole multichannel puncture outfit is placed in the small incision, various instruments can be introduced, the trauma of the patient is relieved, the effect of no scar is generated in the incision, and the puncture outfit is popular among doctors and patients. The single-hole multi-channel puncture outfit mainly comprises a multi-channel platform and a channel. The main function of the multi-channel is to provide a platform for operation machinery to implement and a channel for entering and exiting a human body, and the channel is used for propping open a wound on the abdominal wall and providing support for operation implementation. At present, single-hole multi-channel puncture devices such as Tri-port, quad-port, SilS port and Uni-x port are reported in sequence abroad, and only through-hole type puncture devices are provided, so that a card-filing transition leading-in instrument is necessary;some passages are provided with sealing valves, so that card-resisting transition is not needed; the positioning of the puncture outfit and the incision is different, and the clamping length of the puncture outfit and the incision can not be adjusted by a bell mouth embedding positioning (SilS); the cut (Uni-x) is inserted with a cone, cannot be self-positioned, and must be sutured. The Tri-quad-port is inconvenient to adjust and difficult to operate although the length of the positioning pipeline is adjustable. Above mostly be the integral type structure, take out the excision thing and must wholly lift off, not only troublesome poeration also has the risk that pathological change tissue pollutes the incision. The above introduction devices of various puncture devices use a card transition, a small number of sealing channels are arranged, and gel sealing valves are also adopted, so that the reliability is poor. The defects of the single-hole multi-channel puncture outfit are in urgent need of improvement. On the basis, a single-hole multi-channel puncture outfit (with an authorization notice number of CN202179581U) developed by the Beijing space Kady technical development research institute is improved in channel design, and meanwhile, the puncture outfit adopts a split type structure, and an upper end structure and a lower end pipeline can be detached, so that the puncture outfit is convenient for fetching in the operation process. And the design of domestic single-hole puncture is that the upper multi-channel platform and the lower multi-channel are assembled together by adopting the sleeve or buckle mode (with the authorization notice number CN 206403837U). Because the CO is required to be filled into the body of the patient during the operation2The gas is convenient for operation, so the single-hole puncture outfit is required to have certain air tightness. The mounting portion of the upper end multi-channel platform and the lower channel is often smaller than the diameter of the upper end of the channel, D1 is smaller than D2, and therefore, a surgeon needs to assist in pulling the multi-channel platform apart and then buckling the platform on the channel during surgery, as shown in fig. 1. Meanwhile, in order to better ensure the air tightness, manufacturers often make a curved surface on the matching surface of the multi-channel platform, which is the same as the matching position of the channel, so as to better increase the contact area. However, due to the difficulty in installation, it is often difficult to assemble the surfaces one by one, which results in air leakage during the operation and hinders the operation, as shown in fig. 2.
