Detailed Description

For further illustration of the various embodiments, the utility model is provided with the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments and together with the description, serve to explain the principles of the embodiments. With reference to these matters, one of ordinary skill in the art will understand other possible embodiments and advantages of the present utility model. The components in the figures are not drawn to scale and like reference numerals are generally used to designate like components.

Referring to fig. 1, as an embodiment of the present utility model, there is provided a shapable nasal aspirator including a suction tube 1 and a handpiece 2 connected in front and back, the suction tube 1 being a shapable tube, the handpiece 2 being used to connect a suction device and suck out liquid in a nasal cavity through the suction tube 1, the suction tube being capable of changing an arc as required and maintaining the arc (fig. 2). Because the nasal cavity structure is complicated, the variation is great, and the radian of the suction tube 1 required is different when the operation is carried out on different parts in the nasal cavity, the radian of the suction tube 1 is regulated, so that the suction tube 1 can be more efficiently attracted.

In one embodiment, the suction tube 1 comprises a hose, and the shape maintaining member 11 is arranged on the hose because the hose is soft and is difficult to maintain after the curvature of the hose is adjusted, and the shape maintaining member 11 maintains the hose at a certain curvature, so that the curvature of the suction tube 1 is unchanged during operation, and the suction tube 1 can be shaped. Referring to fig. 1 and 3, in this example, the shape maintaining member 11 is a wire provided on the suction tube wall, and the extending direction of the wire is the same as the extending direction of the suction tube 1. In other embodiments, the wires may be provided in plurality, so that the bending angle of the suction tube 1 can be better maintained.

In this example, the suction tube 1 is a hollow circular tube, the metal wire is arranged on one side tube wall of the hollow circular tube, when the hose and other instruments are inserted into the nasal cavity together, if a certain direction space of the nasal cavity is insufficient to accommodate the suction tube and other instruments simultaneously, the suction tube can be extruded by the coaction of other hard instruments and the inner wall of the nasal cavity, and the position of the suction tube 1 without the metal wire can be deformed, so that the cross section shape of the hose is changed, and the suction tube 1 is adapted to the nasal cavity structure. Thus, the shape change of the suction tube 1 includes a cross-sectional shape change and an arc change.

The wire is only arranged one, so that the variable amplitude of the cross section shape of the suction tube is large, the co-extrusion action of the inner wall of the nasal cavity and other instruments also can not completely seal the cross section of the suction tube 1, and the suction tube 1 can maintain the suction function. In a further step, even if the suction tube 1 is squeezed to be completely closed and not sucked, the operator can find and adjust the positions of other instruments in time during the operation to open the suction tube 1 to restore the suction function.

Referring to fig. 1, in order that the suction tube 1 can be extended deep into the nasal cavity and a portion remains outside the nasal cavity when it is extended deep into the nasal cavity, the length of the suction tube 1 should be controlled to 150-200mm, more preferably 175mm, and the diameter of the suction tube should be 3-5mm, preferably 3mm or 4mm or 5mm. Three different diameters of 3mm, 4mm and 5mm provide a selection space for the operator according to the operation requirement and the size of the nasal cavity of the patient.

The suction tube 1 is connected with the hand piece 2 in a plug-in manner, so that the suction tube 1 is easy to assemble and disassemble and convenient to replace when damaged. The method specifically comprises the following steps of; the one end that is close to suction tube 1 of handpiece 2 is equipped with installation section 21, and installation section 21 is from the middle part of handpiece to the tip extension direction that installation section 21 is located on, and the diameter of installation section 21 reduces gradually to be convenient for suction tube 1 inserts on the installation section 21 from this less tip of diameter, suction tube 1 insert the in-process of installation section 21, the diameter of installation section 21 increases gradually, makes the connection of installation section 21 and suction tube 1 tighter and tighter, the fixed suction tube 1 of the multiple different diameters of adaptation of being convenient for suction tube 1. The outer peripheral surface of the mounting section 21 is provided with a convex part 22, when the suction tube 1 is inserted into the mounting section 21, the inner side surface of the suction tube 1 is connected with the convex part 22, and as the suction tube 1 can deform, the suction tube 1 and the convex part 22 form a seal, namely the suction tube 1 and the handheld piece 2 form a seal connection, so that the suction reliability is ensured.

In one embodiment, the protruding part 22 is a plurality of annular protrusions arranged on the outer peripheral surface of the mounting section 21, and in other embodiments, the protruding part 22 is a spiral protrusion which is formed like a thread by extending spirally along the axial direction of the mounting section 21, so that the suction tube 1 can be spirally mounted on the mounting section 21, and the mounting difficulty of the suction tube 1 is reduced.

Referring to fig. 1 and 2, in operation, when there is more liquid in the nasal cavity or there is a need to suck the solid peeled off from the nasal cavity, the suction tube 1 should be rotated to adjust the suction position thereof in order to suck more thoroughly. Each time the adjustment is performed, the suction tube 1 is pulled out of the nasal cavity, the angle is adjusted, and then the suction tube is inserted, so that the operation is complicated and the time is long, therefore, the rotating piece 3 is arranged at one end of the hand piece 2 far away from the suction tube 1, and the rotating piece 3 is in rotary connection with the hand piece 2, so that the hand piece 2 can selectively rotate around the rotating shaft of the rotating piece 3. The rotating member 3 is also connected to the suction device so that the handpiece 2 can be rotated without moving the suction device, thereby driving the suction tube 1 to rotate in the nasal cavity.

In order to make the attraction more reliable, a rotary sealing connection is provided between the rotary part 3 and the hand piece 2. The rotary member 3 and the hand piece 2 can be in rotary sealing connection through a sealing structure such as a sealing ring.

The middle part of the hand piece 1 is a hand holding part 23, and the outer peripheral surface of the hand holding part 23 is provided with anti-slip protrusions, which can be a plurality of protruding points or a frosted surface formed by frosting the surface of the hand holding part 23. The anti-slip protrusions facilitate the operator to hold the handpiece 1 in one hand and rotate the handpiece 1 to adjust the direction of the suction tube 2. In addition, through simple training, the design of the anti-slip bulge can enable a user to use the nasal endoscope and the aspirator by one hand at the same time, liberate the operation mode of 'two people and four hands', and improve the inspection efficiency.

The workflow of this embodiment is as follows: before the aspirator stretches into the nasal cavity, the aspirator tube 1 is adjusted to a required radian, the aspirator tube 1 is inserted into the nasal cavity for aspiration, and when the aspiration position needs to be changed, the hand piece 2 is rotated to enable the aspirator tube 1 to rotate along with the aspiration position so as to fully aspirate.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
