DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 An embodiment of the utility model discloses an abortion suction tube with an adjustable suction chamber, comprising a gripping portion 1, a suction tube 2 is passed through the gripping portion 1 and an end tube 3 is fixed therein, and the end tube 3 is used to be connected to an external vacuum device;

[0022] The end of the end tube 3 has an adjustment tube 31 which is plugged into the suction tube 2. The adjustment tube 31 is connected to the end tube 3 and penetrates the inside. A locking mechanism 4 is provided between the suction tube 2 and the holding part 1. The locking mechanism 4 is used to lock the position of the suction tube 2.

[0023] In some embodiments, the suction tube 2 has a suction cavity 21 and a threading cavity 22. A circuit board 5 is fixedly installed inside the holding portion 1. A lens unit 6 is provided at the tail end of the suction tube 2. The lens unit 6 is connected to the circuit board 5 through a wire 7. The wire 7 is passed through the threading cavity 22. Specifically, the lens unit 6 described in this embodiment includes a CMOS module and a cold light source. The wire 7 is provided on a flexible FPC board. With the help of the flexible bending ability of the flexible FPC board, the suction tube 2 can move forward and backward. The connection method and principle of the above structure are prior art and will not be elaborated here.

[0024] On the basis of the above-mentioned embodiment, in this embodiment, a seal is installed on the end of the adjusting tube 31, and the seal is preferably configured as a sealing ring embedded in the outer side of the adjusting tube 31 to ensure the sealing between the two. A through hole 23 is opened on the end face of the threading cavity 22, and one end of the wire 7 is passed outward along the through hole 23 and is electrically connected to the circuit board 5.

[0025] In some embodiments, the locking mechanism 4 in the utility model includes a button 41 inserted into the holding portion 1, a stop plate 42 is fixedly installed on the inner side of the holding portion 1, a spring 43 is fixedly installed between the stop plate 42 and the button 41, a bending plate 44 is also fixed at the bottom of the button 41, and a fixed structure is arranged between the bending plate 44 and the suction tube 2.

[0026] On the basis of the above embodiment, the fixing structure described in this embodiment includes a latching tooth 45 fixed on the bending plate 44, and a plane portion 24 is opened at the bottom of the suction tube 2. It should be noted that in this embodiment, the suction chamber 21 and the threading chamber 22 are separated by a partition inside the suction tube 2. The plane portion 24 is formed by the above-mentioned partition after a notch is opened at the bottom of the suction tube 2. A plurality of teeth 46 that are engaged with the latching tooth 45 are provided on the plane portion 24.

[0027] That is, when adjusting the length of the suction chamber 21, first press the button 41 to drive the bending plate 44 to move downward. The bending plate 44 is roughly U-shaped. When the bending plate 44 moves downward, it will drive the latch 45 to separate from the tooth 46 on the flat portion 24. At this time, the length of the suction tube 2 can be freely adjusted forward and backward, thereby changing the length of the suction chamber 21. After the adjustment is completed, release the pressure on the button 41. Under the push of the spring 43, the button 41 is reset and the latch 45 is again engaged with the tooth 46 to complete the positioning of the suction tube 2.

[0028] Furthermore, in this embodiment, in consideration of limiting the forward and backward movement of the suction tube 2, a guide frame 11 is fixedly installed inside the holding portion 1, and the guide frame 11 slides in the planar portion 24 to limit the sliding of the suction tube 2, that is, the movement of the suction tube 2 is limited by sliding the guide frame 11 in the notch.

[0029] In summary, the utility model adopts a plug-in design between the suction tube 2 and the end tube 3, so that the length of the suction tube 2 can be adjusted according to the surgical requirements. This design is intended to improve the adaptability of surgical tools so that they can better adapt to the specific conditions of different patients;

[0030] In addition, during the surgical operation, the doctor can extend or shorten the suction tube 2 by simply pressing the button 41 to adapt to different surgical depths. This instant length adjustment function avoids the tedious steps of replacing suction tubes of different lengths in traditional surgery, significantly improving surgical efficiency.

[0031] In addition, the ease of operation of the suction tube adjustment device is also a highlight. During surgery, the doctor only needs to operate the button 41 with one hand to achieve precise control of the length of the suction tube 2. This design takes into account the convenience of surgical operation and the doctor's experience.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
