The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

As shown in fig. 1 to 5, the cartesian needle for a microsurgery of the present embodiment includes a needle 1, a handle 2, a capsule 3, a pipeline 5 and a joint 6, wherein the needle 1 is disposed at one end of the handle 2, the pipeline 5 is disposed at the other end of the handle 2, and the pipeline 5 is communicated with the needle 1 through the handle 2. Capsule 3 sets up in the chamber 21 that holds of handle 2, and capsule 3 is located 2 upper surfaces of handle, and 3 edges of capsule and 2 butt parallel and levels of handle to enlarge the volume of capsule, the capsule is inside level and smooth, and the hole is empty tube structure, and the capsule is the arc resilience, thereby has bigger volume. The surface of the capsule 3 is provided with a through hole 31 which enables the interior of the capsule to be communicated with the external environment, the through hole 31 is communicated with the needle 1, the joint 6 is arranged at the tail end of the pipeline 5, and the joint 6 is used for being connected with an active suction device. The handle 2 is provided with the pit 22, the hand is pinched in the pit, the hand pinching angle of the pit is 60 degrees, the pit has a blocking effect, the hand is prevented from sliding during operation, and the operation is more convenient. A plurality of pockets 22 are spaced around the handle. In the above technical solution, in use, the cartesian needle may have two operation modes: an active pumping mode and a passive pumping mode. In active aspiration mode, the trocar may be connected through the connector 6 to a surgical console that may actively aspirate fluids. In the active suction mode, the doctor covers the through holes 31 on the capsule 3 (for example, with the fingers) to prevent air from being sucked through the through holes on the capsule. In the passive suction mode, a cartesian needle is used without connection to any surgical console. In such embodiments, because the pressure within the body part (e.g., the patient's eye) is higher than atmospheric pressure, when the surgeon inserts the trocar into the body part, liquid/gas may flow from the body part into the trocar and out through the through-holes on the capsule 3. In other words, in the passive suction mode, the through-holes on the capsule may serve as liquid outlets. In this embodiment, the capsule is a silicone capsule, and the silicone capsule is a soft rubber, has elasticity, and can rebound after being pressed, and the joint is a luer joint. With the above technical solution, the cartesian needle can be used for the extraction of fluids, internal drainage of subretinal fluid, and simultaneous or sequential exchanges (gas-liquid, gas-gas, liquid-liquid, etc.). The flute needle instrument is provided with the soft-head needle head, so that the flute needle instrument can not cause any tissue injury of the human body when being contacted with any tissue of the human body, the doctor can hold the flute needle instrument by hand more conveniently and smoothly, two modes can be realized, the operation is simple,

in this embodiment, the handle 2 has a support rod 4, and the pipeline 5 extends into the support rod 4, so as to facilitate holding operation by medical staff. A connecting part 7 is arranged in the support rod 4, and the pipeline 5 is connected with the connecting part 7, so that the pipeline 5 is connected with the handle. The diameter of the supporting rod 4 is contracted from the end of the handle 2 to the direction of the pipeline end, so that the appearance of the whistle needle is streamline, and the hand-held feeling and the pressing feeling are good.

The flute needle for the micro operation of this embodiment can realize two kinds of mode, and it is better to use the flexibility, easy operation, and the doctor is handheld better convenient handy.

The above description has been made on the cartesian needle for the micro-surgery of the present invention, but the present invention is not limited to the above specific embodiments, and various modifications and changes can be made without departing from the scope of the claims. The present invention includes various modifications and alterations within the scope of the claims.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
