Puncture outfit easy for flexible operations of apparatus and using method

Abstract

The invention discloses a puncture outfit easy for flexible operations of an apparatus and a using method. The puncture outfit comprises a casing pipe, puncturing rods, a sealing element and a sealingcover, wherein the sealing element is detachably mounted at the upper end of the casing pipe in a sealing manner, the sealing cover is detachably mounted on the side away from the casing pipe, of thesealing element, in a sealing and buckling manner, the cone end of each puncturing rod sequentially penetrates through the sealing cover and the sealing element in a sealing manner to be inserted andlocated in a puncturing rod passage located in the casing pipe, an air receiving pipe is arranged on the sealing element, and the inner end of the air receiving pipe penetrates through the puncturingrod passage in the casing pipe; and a valve port achieving the sealing effect when pneumoperitoneum is established is arranged on the sealing cover, and a sealing lip achieving the sealing effect when the apparatus penetrates through is arranged on the sealing element. In the inserting and drawing process of the apparatus, the sealing effect can be achieved only by one layer of the sealing element, the inserting and drawing friction when the apparatus penetrates through can be greatly reduced, the displacement of the casing pipe caused by the inserting and drawing process of the apparatus canbe avoided, surgery risks can be reduced, convenience is provided for operations of a doctor, and besides, pain of patients can be well alleviated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a puncture device which is easy to operate flexibly and a use method thereof. Background technique [0002] During the process of endoscopic minimally invasive surgery, the doctor uses a puncture device to puncture the patient's abdominal cavity and chest cavity, and delivers gas to the patient's body, establishing a channel for the endoscope and endoscopic minimally invasive surgical medical equipment to enter and exit the patient's body from the outside. . Among them, disposable puncture devices are more favored by doctors and patients because of their advantages such as sharper, easier to transport, easier to use, prevent cross-infection, and strong sealing. Especially in more economically developed regions, the market space for disposable trocars is wider. With the rapid popularization of endoscopic minimally invasive surgery in my country, trocars, as an essent...

Problems solved by technology

The problem with the above-mentioned seals is that, for the design of the sleeve seal, no matter whether a straight cut or a cross cut is used, when an instrument is inserted or pulled out, the cut on the sleeve seal will be stretched by the instrument and will be deformed. For the seal cover seal, although the funnel-shaped seal ring can play a good seal, this method will cause a large insertion and withdrawal force when the instrument passes, and there is only a gap between the trocar and human tissue. With little fixing force, excessive insertion and withdrawal force of the instrument through the funnel-shaped sealing ring can easily cause the trocar to shift, causing additional damage to the patient or affecting the efficiency of the operation; in addition, the plum-blossom valve-shaped sealing member solves the problem of smooth insertion and extraction. However, when a device passes through, the valve will be stretched and it is extremely easy to leak, so this solution does not effectively solve the sealing problem
