New description: 【New technology field】 This creative department belongs to the abandoned type of surgery n material, its external clock (4) design can provide abdominal disintegration difficult towel (four) road, _ fixed in the abdominal cavity position And through the design of Wei Mi Lai, you can use a variety of different sizes of micro-invasive appliances can be used to improve the efficiency of the trocar. [Prior Art] Yuke _ Progress, Lai surgery (abdominal (four) ocular surgery) has been widely used to replace the traditional surgical methods that require large wounds. Patients can reduce the discomfort caused by surgery and improve the inconvenience of bed rest after surgery. The trocar is often used in minimally invasive surgery (four), and the early half is made of metal plus. 'There can be repeated fine after each batch is finished. Recently, plastic-based puncture has begun to appear. In addition to retaining the original function, the plastic _ & no cold feeling and can be abandoned, bringing more convenience. In the past, 2 punctures were made of metal material, and the tip of the product was inserted into the abdominal cavity directly from the wound of the abdominal cavity using a solid-fixed taper knife 77. [New content] The new product created by 'providing medical personnel to construct the cannula 3 (C_la) when performing minimally invasive abdominal surgery can make other minimally invasive surgical instruments enter the human abdominal cavity through the channel. (4) 'Field f bayonet (t_f) The new reading cavity arrives on the wall of the cannula, which is designed to be detachable. The 4 M369134 can be easily positioned. In order to make the operator's force easy, the grip 5 is designed at the 180-degree position of the sleeve surface design, which can be easily applied without loosening. The front end of the inner tube l (Obtulator) has a circular arc-shaped telescopic blade 18, which can be forced outwardly at the force applied by the cassette 2 to achieve the function of assisting cutting. Overall, the creation can provide a difference from the current market. The trocar produces α-port, and it has the advantages of easy operation, no leakage, good air tightness and convenient operation. [Embodiment] In order to enable the reviewing committee to have a clearer understanding of the technical content of the present invention, a specific embodiment will be described as follows: Please refer to Figure 1 for an appearance of the product of the novel puncture knife. Referring to FIG. 2, the novel puncture knife of the present invention mainly comprises two parts, one of which is a universal cover piece 6 for passing the surgical tool and including the elastic isolation airtight bushing 7, and the universal cover piece 6 Referring to the sleeve 3, please refer to FIG. 3, one of which is the inner tube 1. The universal cover sheet 6 includes a top-and-bottom structure, and in the actual cover, the cover sheet is composed of an upper cover 61 and a lower cover 62, and the β-up cover 61 and the lower cover 62 are coupled in a snap-fit manner. And the elastic isolation airtight bushing 7 is fixed by the upper and lower covers. In the present embodiment, the sleeve 3 includes a grip 5 and an air guiding hole 4, and the upper edge of the sleeve 3 can be detachably coupled with the lower cover 62 of the universal cover sheet 6. The lower edge of the sleeve 3 has a horizontal level. Threaded structure for insertion into the patient's abdomen and the patient's abdomen 5 M369134. The skin layer is stuck and the nest is placed in the patient's abdomen. Please refer to Figure 7 for the _ Xincai thorn-like shouting explosion map. As shown in the figure, the inner tube 1 includes a circular arc-shaped telescopic knife 8, a rod 13 coupled to the circular-shaped telescopic blade 18, a protective tube 16, a dome-shaped upper cover 14, and a circular lower cover 15. 'The dome-shaped upper cover and the circular lower cover 15 are combined in a snap-fit manner. Further, between the dome-shaped upper cover and the circular lower cover 15, an accommodation space is defined to accommodate the -spring 1G, the spring η and the double arm member 12. The upper edge of the protection tube 16 includes a cassette 2, and the rod 2 and a round rod 17 are combined with a spring 1G, a spring 11 and a double-arm structure 12 into a retracting system mechanism, under the protection tube 16 When the epidermis is left, the circular telescopic knife 18 will be pushed out to cut the skin of the epidermis. When the protective tube 16 _ goes to the real skin and the subcutaneous tissue is pressed, the spring n acts to push the two arms u The round rod 17 causes the spring ίο to move, and the round solitary telescopic knife β 1S is retracted to complete the action of cutting the skin layer %. Thereafter, the cannula 3 is continuously pressed into the patient's abdomen, and while the indentation is applied, the 3 anti-off barb 9 will be stuck with the epidermis layer to keep the cannula 3 fixed in the abdomen of the patient. The above-described embodiments are merely illustrative of the principles of the present invention and its progress, and are not intended to limit the scope of the present invention. The scope of protection of this creation should be as described in the scope of the patent application described later. 6 M369134
