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.

Example Embodiment

[0044] Example 1

[0045] like Figure 1-12 As shown, the present invention is a trocar that is easy to operate flexibly, including a cannula 1, a puncture rod 2, a sealing member 3 and a sealing cover 4, and the sealing member 3 is detachably sealed and mounted on the cannula 1. At the upper end, the sealing cover 4 is detachably mounted on the side of the sealing member 3 facing away from the casing, and the tapered end of the puncture rod 2 is sealed through the sealing cover 4 and the sealing member 3 in sequence and inserted into the casing 1 inside the puncture rod channel 1-1, the sealing member 3 is provided with an air connection tube 3-4, and the inner end of the air connection tube 3-4 is connected with the puncture rod channel 1-1 inside the casing 1; The sealing cover 4 has a valve port that acts as a seal when the pneumoperitoneum is established, and the sealing member 3 has a sealing lip that acts as a seal when the instrument passes through.

Example Embodiment

[0059] Example 2

[0060] like figure 1 , 13 As shown in ~15, a puncture device that is easy to operate flexibly in the embodiment 1 is used in conjunction with an endoscopic stapler, and the specific operation steps are as follows:

[0061] Step 1: Put the palm against the grip part 2-1 of the puncture rod 2, hold the support rod 2-2 with your fingers, and puncture the patient's abdominal cavity with the puncture device, and insert the cannula 1 along with the puncture rod 2 to the designated abdominal cavity of the patient In the deep position, hold the grip part 2-1 and pull out the puncture rod 2 from the casing 1 (as attached figure 1 shown);

[0062] Step 2: Connect the one-way valve 6 to the gas injection device, inject gas into the patient's abdominal cavity and establish a pneumoperitoneum with a certain pressure, and disconnect the one-way valve 6 from the gas injection device;

[0063] Step 3: Pass the jaws of the endoscopic stapler 7 through the instrument chan...

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...
