Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the ordinary skilled in the art without creative work include but not limited to adding new technical features, and replacing any technical features of the present invention with equivalent technical features to obtain a new technical solution, which all belong to the protection scope of the present invention.
In the present invention, it is noted that relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.
Furthermore, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like are used herein to indicate orientations or positional relationships based on the drawings, and are used for convenience in describing the present invention, but do not indicate or imply that the device or element so referred to must have this particular orientation, be operated in a particular orientation configuration, and not be construed as limiting the present invention.
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments thereof.
In this specification, the direction of entry into the patient is forward and the direction is backward.
Referring to fig. 1, the otological operation aspirator capable of connecting a syringe needle comprises an aspiration cavity 10, wherein the front end of the aspiration cavity 10 is fixed with the rear end of an aspiration port 20.
The suction cavity 10 and the suction port 20 are both hollow structures with two through ends, and the hollow parts of the two are communicated.
Referring to fig. 3, the suction port 20 fixes the suction head 40. Particularly, the suction head 40 is a small-sized suction head, and if a large-sized suction head is needed, the suction head 20 directly serves as the large-sized suction head, and the large-sized suction head is used for performing suction operation; if a small-sized suction head is used, a small-sized suction head for performing suction work is fixed to the suction port 20.
Referring to fig. 2, the suction chamber 10 is connected to a syringe 30, specifically, a needle holder (a thin tube 31 at the front end of the syringe) of the syringe 30 extends into the suction chamber 10, the suction chamber 10 is in interference fit with the needle holder of the syringe 30, and the syringe serves as a suction power source during suction operation.
The suction port 20 is tapered to facilitate fixation of the suction port 20 to the suction head 40.
In order to facilitate the suction port 20 to serve as a large-sized suction head, the outer end of the suction head 40 is a tapered suction port 22, and the taper angle of the space where the tapered suction port 22 is located is larger than that of the space where the suction port 20 is located.
Referring to fig. 3, in order to control the suction pressure, a pressure reduction control hole 24 is formed in the wall of the suction chamber 10 in the proceeding direction.
Referring to fig. 1, the outer side surface of the rear end (the end connected to the syringe 30) of the aspiration lumen 10 is provided with a friction region 12 for the convenience of holding.
The working principle is as follows: after the suction chamber 10 and the syringe 30 are assembled, the suction chamber 10 is used as a power source for suction.
If a large size suction is used, the tapered suction port 22 is used as a suction head, and if a small size suction is used, the suction head 40 is assembled.
Then, a simple suction operation can be performed by using the syringe 30 as a suction power.
In which the magnitude of the suction force can be controlled by closing or opening the pressure reduction control hole 24 with the hand.
Is suitable for ear surgery.
See the prior art for additional details.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
