Embodiment 1

[0028] Embodiment one: see Figure 1-12 , a disposable sterile percutaneous enterostomy device, comprising a puncture needle, a thin guide wire, a coaxial dilator, a positioning fixer, an adjustment pull wire, a thick guide wire, a dilation tube and an enterostomy tube. The puncture needle is 21G (0.75mm) or 22G (0.7mm), which can pass through a thin guide wire with a diameter of 0.018Inch (0.46mm). The coaxial dilator is a three-piece set. The coaxial dilator includes an inner needle, a middle sheath and an outer sheath. The diameter of the outer sheath is 6Fr (1.98mm), the length of the sheath is 20cm, the diameter of the middle sheath is 4Fr (1.32mm), and the inner needle is 22G (0.7mm), the middle sheath and the inner needle are both 20cm long, the middle sheath and the inner needle can both pass through a 0.018inch (0.46mm) guide wire, and the outer sheath can pass through 0.038inch (0.89mm) and 0.018inch (0.46mm) at the same time guide wire. The diameter of the thin gu...

Embodiment 2

[0034] Embodiment two: see Figure 13-14 , Embodiment 2 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the developing device is a plurality of air chambers arranged inside the positioning fixture body. Due to the existence of the air chamber, the main body of the positioning fixture can be visualized under X-ray or ultrasound. The positioning fixture of this embodiment only includes one material, which is better in biosolubility and degradability.

Embodiment 3

[0035] Embodiment three: see Figure 15 , Embodiment 3 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the small enterostomy tube includes a first bending ring and a second bending ring, and the first bending ring is the design of the proximal end. For natural forming, the second bending ring can be designed to be formed by drawing with wires, or both bending rings can be designed to be formed naturally without external pulling wires. The enterostomy tube is equipped with two-stage bending rings, which can reduce the risk of slippage of the enterostomy tube.

Abstract

The invention discloses a disposable aseptic percutaneous small enterostomy device, which comprises a puncture needle, a thin guide wire, a coaxial dilator (a 3-piece set, including an inner needle, a middle sheath and an outer sheath), a positioning fixer, Adjust the pull wire, thick guide wire, dilation tube and small enterostomy tube. The positioning fixture body includes a positioning fixture body made of biodegradable materials, a pull wire fixing groove and a developing device arranged on the positioning fixture body. The disposable sterile percutaneous gastroenterostomy device of the present application only needs to use a puncture needle to puncture a small hole on the patient's body surface, the wound is small, and the damage to the patient is small, which is beneficial to the later recovery and reduces the risk of infection; The positioning fixer can fix the intestinal tract in a targeted manner to facilitate subsequent operations.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and mainly relates to a disposable aseptic percutaneous enterostomy device. Background technique [0002] Small bowel ostomy is a commonly used treatment method in the process of disease treatment. The existing ostomy technology generally requires general anesthesia. The surgeon makes an incision on the skin surface. The incision size is large, which causes great pain to the patient and is not easy to heal. There is a greater risk of infection. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a disposable aseptic percutaneous enterostomy device. [0004] Technical scheme of the present invention is: [0005] A disposable sterile percutaneous small enterostomy device, including a puncture needle, a thin guide wire, a coaxial dilator (a 3-piece set, including an inner needle, a middle sheath, and an outer sheath), a positi...
