Description

Saliva suction tube

Technical Field

The utility model relates to a medical instrument, in particular to a saliva suction tube.

Background

In the tooth extraction operation, especially in the process of extracting the embedded wisdom tooth, the difficulty of taking out broken roots and residual roots (namely, the so-called root picking) is high, and the poor visual field further increases the operation difficulty. On one hand, the light is difficult to directly irradiate at the deep position of the tooth socket, so that the illumination is poor. On the other hand, saliva and bleeding cause poor vision in the surgical field.

In clinical operation, the lighting angle of the lighting needs to be repeatedly adjusted, and the saliva suction tube stretches into the tooth socket to suck blood saliva, so that a short clear view of one or two seconds is formed to observe and judge the tooth root condition.

The tip of a conventional saliva suction tube is relatively thick and is not suitable for insertion into the socket for sucking saliva and blood.

CN 215503508U proposes a saliva suction tube whose tip is formed in a tapered shape to facilitate insertion into the alveolus, but the problem of unclear vision at the alveolus cannot be changed at all.

Disclosure of Invention

In view of the above problems, the present utility model proposes a saliva suction tube for sucking saliva or bleeding from a socket; it can direct illumination to the alveolus department for the field of vision in operation district is clear.

The saliva suction tube of the present utility model for sucking saliva or bleeding in a socket, comprises: a tube body; the pipe body is made of a bendable plastic pipe; the lower end of the tube body is formed into a tapered tip to extend into the socket;

a metal wire is formed in the inner wall of the pipe body for helping the pipe body to maintain a bent shape after the pipe body is bent;

two wires are also formed in the inner wall of the pipe body; the lower ends of the two wires extend to the outer side of the tube body at the upper part close to the conical tip, are connected with a lamp holder, and are provided with LED lamp beads; the upper ends of the two wires extend to the outer side of the pipe body at the lower part of the upper end of the pipe body, and the upper ends of the wires are provided with plugs;

the upper end of the pipe body is detachably combined with a battery compartment;

a battery is arranged in the battery bin to supply power for the LED lamp beads; a socket is formed at the lower part of the battery compartment for inserting the plugs at the upper ends of the two wires; a switch is formed at the upper part of the battery bin; the battery, the switch and the LED lamp beads are connected in series to form a power supply loop.

Preferably, a C-shaped clip is formed at a side of the battery compartment, and the battery compartment is rotatably mounted to an upper portion of the tube body by the C-shaped clip.

By means of the saliva suction tube, the conical tip at the lower end of the tube body can easily extend into the alveolus to suck saliva or bleeding out of the alveolus; the LED lamp beads at the positions close to the lower ends can be positioned at the positions capable of directly illuminating the operation area by bending two wires, so that a clear view is provided for smooth operation.

Detailed Description

Hereinafter, the saliva suction tube of the present utility model will be described in detail with reference to the accompanying drawings.

The saliva suction tube of the present utility model for sucking saliva or bleeding in a socket, comprises: a tube body 10.

The tube body 10 is made of a plastic tube which can be bent; the lower end of the tube body 10 is formed as a tapered tip 11 to protrude into the socket.

A wire 40 is formed in the inner wall of the tube body 10 for helping the tube body 10 to maintain a bent shape after the tube body 10 is bent. The wire 40 may be formed thicker or as a plate-like wire, which increases the cross-sectional area of the wire without increasing the wall thickness, providing greater flexibility to the tube body and facilitating retention of the tube body in bending.

Two wires 21 are also formed in the inner wall of the tube body 10; the lower ends 21a of the two wires 21 extend to the outside of the tube body 10 near the upper part of the conical tip 11 and are connected with a lamp holder 23, and the lamp holder 23 is provided with LED lamp beads 22; specifically, a first strand of the two strands of wires is connected to the anode of the LED lamp bead, and a second strand of the two strands of wires is connected to the cathode of the LED lamp bead; the upper ends of the two wires 21 extend to the outside of the pipe body 10 at the lower portion of the upper end of the pipe body 10, and the upper ends of the two wires 21 are fitted with plugs 34. The two wires 21 are flexible enough so that the position of the LED beads 22 can be adjusted in use by bending their lower ends 21a so that they can directly illuminate the surgical field without obstructing the field of view. In addition, the rear side of the lamp holder can be formed into a bowl-shaped curved surface, and a reflecting layer is arranged on the curved surface, so that the lamp holder can collect light, and the lamp holder is also a conventional design of the LED lamp and is not repeated.

The upper end of the tube body 10 is detachably coupled with a battery compartment 30.

A battery 35, such as a button cell, is mounted within the battery compartment 30 to power the LED light beads 22. A socket 33 is formed at the lower part of the battery compartment for inserting a plug 34 at the upper ends of the two wires 21; a switch 32 is formed at the upper part of the battery compartment 20; after the plug 34 is inserted into the socket 33, the first wire is connected to the positive electrode of the battery 35 after passing through the plug, the socket and the switch in sequence; the second wire is connected to the negative electrode of the battery 35 after passing through the plug and the socket in sequence. The battery 35, the switch 32 and the LED lamp beads 22 are connected in series to form a power supply loop, and the switch 32 controls the on-off of the loop.

The side of the battery compartment 30 is formed with a C-shaped catch 31, and the battery compartment 30 is rotatably mounted to the upper portion of the tube body 10 by the C-shaped catch 31. By rotating the C-shaped catch 31, the position of the battery compartment 30 can be adjusted so that it does not obstruct the field of view of the surgical field.

When in use, the tube body is completely inserted into the tooth socket after being conveniently stretched into the oral cavity; then, the lower ends of the two strands of wires are bent, so that the LED lamp beads are positioned at proper positions, and the visual field of the operation area is not influenced on the premise of ensuring the illumination of the operation area; after the switch is pressed and the power is turned on, the LED lamp beads can illuminate the operation area.
