Problems solved by technology

Moreover, in the process of establishing many surgical channels, damage to the surrounding areas of the channel is inevitable. The channel is usually established by expanding from the outside to the inside, which easily leads to the problem that the internal channel space is small and the entrance space is large. Or the channel is usually established and recovered by passive expansion and contraction, which makes it difficult to recover and take out the channel, and easily causes secondary damage to the surrounding channel

Embodiment 1

[0040] like Figure 1-3As shown, the external hanging component is a surgical channel establishment component, and the multifunctional puncture device includes an endoscope 3, a puncture needle 1, a valve body 301 and a channel component, wherein the endoscope 3 is arranged inside the puncture needle 1 through the valve body 301, and the puncture A fixing rubber ring is arranged on the mating surface of the needle 1 and the endoscope 3, an air bag 303 is arranged on the outside of the puncture needle 1, and a channel component is wrapped on the outside of the air bag 303; the puncture needle 1 is cylindrical at one end and has a thread at one end and a fixing table at the other end. A101 and fixing table B102, the endoscope 3 is provided with a hanging table 3001 which is matched with the fixing table A101, the antifouling cover A2 is made of medical transparent material and is fixed on the threaded end of the puncture needle 1 by screw connection, and one end of the valve body...

Embodiment 2

[0047] The difference between this embodiment and Embodiment 1 is that: Figure 8-10 As shown, the lock piece 8 includes a lock body 15, a lock tongue 16, a horizontal pull pin 17, a spring piece 18, and a vertical pull pin 19. The lock body 15 is a hollow cylindrical body with a square through groove in the radial direction, and the lock tongue 16 is U-shaped, the lock tongue 16 passes through the square through slot on the lock body 15, the bottom edge of the lock tongue 16 is provided with a circular hole through which the fixing rod 6 can pass, and the width of the two U-shaped side openings of the lock tongue 16 is fixed The width of the gap on the rod 6 is equal, one end of the spring piece 18 is fixed on the lock tongue 16 by a vertical pull pin 19, the other end of the spring piece 18 is against the outside of the lock body 15, and the horizontal tie rod 17 passes through the two U-shaped sides of the lock tongue 16 The lock tongue 16 is fixed in the square through gro...

Embodiment 3

[0050] The multifunctional puncture device in this embodiment can realize the ablation operation under visual puncture, such as Figure 11 As shown in the figure, a fixing rubber ring 14 is provided at the mating surface of the puncture needle 1 and the endoscope 3, and the multifunctional sleeve 9 is a multi-cavity hollow cylinder. Minimally invasive medical instruments such as electrode ablation gun 10 soft endoscope 11 water tube 12 can pass through the hollow cavity of multifunctional sleeve 9 .

Abstract

The invention discloses a multifunctional puncture device, comprising a puncture needle, an endoscope, an antifouling cover A and an external hanging component, wherein the endoscope is arranged inside the puncturing needle, and the external hanging component is arranged outside the puncturing needle. In the multifunctional puncture device of the present invention, the puncture needle is combined with the endoscope and the external hanging components, which realizes the visualization of the puncturing process, improves the success rate of the puncture, and reduces the secondary damage. function combination.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a multifunctional puncturing device. Background technique [0002] When surgical treatment of diseases, it is necessary to accurately puncture the lesion or establish a surgical channel, such as external ventricular drainage, ventriculoperitoneal shunt, closed thoracic drainage, etc., for brain tumor or cerebral hemorrhage surgery, spine surgery, etc. To establish a channel, these operations require precise puncture to reach the surgical site to ensure the success of the operation. The existing puncture needle or the operation of placing the surgical channel is non-visual, sometimes causing unsuccessful or serious secondary injury. In order to avoid the failure of the operation due to the wrong puncture direction, a visual puncture needle under the guidance of navigation or ultrasound is required to assist the operator to observe the puncture direction, location, and surrounding ...
