Embodiment 1

[0085] image 3 and 4 Two structural implementations of the nozzle 1 are shown. In this example, the elbow portion 112 is a 180-degree elbow, and the nozzle hole 12 is formed on the convex head 113c. The difference between the two structural implementations is mainly in the convex head 113c shape.

[0086] Please refer to image 3 and 4 The structure of the nozzle 1 provided in this embodiment includes: a liquid inlet pipe 11 and a nozzle hole 12, the liquid inlet pipe 11 is used to provide a flow path for the high-pressure liquid to flow to the nozzle hole 12, and the near end of the liquid inlet pipe 11 is provided with a nozzle hole 12 , the remote end is connected to a high-pressure liquid supply source, and the high-pressure liquid flows from the liquid inlet pipe 11 to the nozzle hole 12; the nozzle hole 12 is used to form a liquid jet 12a when the high-pressure liquid flows through. Wherein, the liquid inlet tube 11 includes: a distal straight pipe portion 111, an e...

Embodiment 2

[0103] This example provides a nozzle with another structure and a molding method for the nozzle. The difference between the nozzle structure in this example and the nozzle structure in Embodiment 1 is that when the elbow portion 112 is a 180-degree elbow, the nozzle hole 12 is formed on the pipe wall of the proximal straight pipe portion 113, and is aligned with the convex head 113c forms a gap. Wherein, the nozzle hole 12 can be formed on the inner tube wall or the outer tube wall of the proximal straight tube portion 113 . The nozzle forming method in this example is different from the nozzle forming method in Embodiment 1 in that in S3, the nozzle hole 12 is formed on the tube wall of the proximal straight tube portion 113 and forms a distance from the convex head 113c. Wherein, the nozzle hole 12 can be formed on the inner tube wall or the outer tube wall of the proximal straight tube portion 113 . When the nozzle hole 12 is formed on the tube wall of the proximal strai...

Embodiment 3

[0105] Figure 7 and 8 Two other structural implementations of the nozzle 1 are shown. In this example, the elbow portion 112 is a 90-degree elbow. The difference between the two structural implementations mainly lies in the shape of the convex head 113c.

[0106] Please refer to Figure 7 and 8 The structure of the nozzle 1 provided in this embodiment includes: a liquid inlet pipe 11 and a spray hole 12, and the liquid inlet pipe 11 includes: a distal straight pipe portion 111, an elbow portion 112, and a proximal straight pipe portion 113, and the distal straight pipe Part 111, curved pipe part 112 and proximal straight pipe part 113 all have pipe wall and pipe lumen respectively. The inner cavity of the tube continues to flow toward the nozzle hole 12, and when passing through the nozzle hole 12, various required liquid jets 12a of different shapes are formed and ejected.

[0107] The far-end straight pipe part 111 has a first liquid inlet 111a and a liquid outlet 111b....

Abstract

The invention discloses a jet nozzle, a water jet scalpel apparatus, a jet nozzle molding method and a water jet scalpel apparatus molding method. The jet nozzle comprises a liquid inlet tube and a jet hole; the liquid inlet tube comprises a distal straight-tube part, an elbow part and a proximal straight-tube part, wherein the distal straight-tube part is provided with a first liquid inlet and aliquid outlet; the elbow part has two open ends, wherein one of the ends communicates with the liquid outlet; the proximal straight-tube part is provided with a second liquid inlet and a convex-side end enclosure; the second liquid inlet communicates with the other end of the elbow part; the jet hole is molded in a convex side of the convex-side end enclosure, wherein the liquid inlet tube offersa pathway that liquid flows towards the jet hole, and the pathway can smoothly transit to the jet hole when liquid passes through the convex-side end enclosure; and by virtue of the jet hole, the liquid, which passes through the jet hole, is jetted out in the form of a liquid jet flow. According to another embodiment, the jet hole is molded in the tube wall of the proximal straight-tube part and keeps a distance with the convex-side end enclosure. In a process that the liquid flows towards the jet hole, the flowing passage (the pathway) smoothly transits to the jet hole from a tube inner cavity of the proximal straight-tube part, so that liquid loss is effectively reduced.

Description

technical field [0001] The present invention relates to an apparatus for generating liquid jets and a molding method of the apparatus, in particular to a nozzle, a water jet apparatus, a nozzle forming method and a water jet apparatus forming method. Background technique [0002] Such as figure 1 , the nozzle 1 can make the liquid passing therein, such as high-pressure liquid, flow to the nozzle hole 12, and when the liquid flows through the nozzle hole 12, it will form a liquid jet 12a, and the liquid jet 12a is ejected from the nozzle hole 12. When the liquid passed into the nozzle 1 is a high-pressure liquid, the liquid jet 12a ejected from the nozzle hole 12 has a high-pressure characteristic. At this time, the liquid jet 12a can be used to cut different objects, such as in minimally invasive surgery for surgery. The cutting of various tissues or organs of the patient's body. Common nozzle 1 structures refer to figure 1 As shown, it is composed of a liquid inlet pipe ...
