Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a suction aid device for abortion surgery. Background Technology

[0002] The negative pressure suction tube for abortion uses negative pressure to suction embryonic tissue out of the uterine cavity through the negative pressure channel of the tube, thus achieving the purpose of induced abortion. Currently, commonly used negative pressure suction tubes for abortion include a stainless steel suction tube (which needs to be inserted into the uterine cavity) and a flexible tube that connects to the negative pressure device at the rear. However, the existing suction tube connectors are inconvenient to connect to the suction head, are difficult to tighten, and are prone to falling off. Furthermore, when suctioning tissue from different locations within the uterine cavity, the existing suction tube needs to be moved and swung. Since a large portion of the suction tube is located inside the vagina, such significant swaying and movement can easily cause discomfort to the patient and may damage the vagina. Summary of the Invention

[0003] The present invention aims to provide a suction aid device for abortion surgery to solve the problems of unstable connection of existing suction tubes and easy damage during operation.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A suction aid device for abortion surgery includes an insertion tube and a suction tube. The front end of the insertion tube is used to extend into the uterus for negative pressure suction. The suction tube is used to connect to an external negative pressure device to provide negative pressure. The insertion tube and the suction tube are detachably connected. The insertion tube includes a suction head and a main tube. The suction head is provided with a suction port, a miniature camera, and a light source. The suction port is a negative pressure suction port. The miniature camera is used to observe the suction port. The miniature light source is used to assist the miniature camera in observing the suction port. A corrugated tube is provided between the suction head and the main tube. Several traction wires are connected to the tail end of the suction head. A fixing ring is connected to the tail end of the main tube. A control ring is provided outside the fixing ring. Several universal balls are provided between the fixing ring and the control ring. The universal balls are movably connected to the fixing ring and fixedly connected to the control ring. The traction wires are located inside the wall of the main tube. The tail end of the traction wires is fixedly connected to the control ring. By moving the control ring to different positions, the suction head can swing in various directions.

[0006] Furthermore, the suction tube is made of soft rubber.

[0007] Furthermore, the front end of the suction head has a bent structure.

[0008] Furthermore, four pull lines are connected to the head and tail of the suction device, with the beginning of each pull line connected to one of the four quadrant points at the head and tail.

[0009] Furthermore, the end of the insertion tube is tapered, which facilitates the insertion of the end of the insertion tube into the suction tube, making the suction tube and the insertion tube detachably connected.

[0010] The principle and beneficial effects of this technical solution: In this invention, the insertion tube and the suction tube are connected by a conical structure, which allows for quick installation and easy disassembly. A miniature camera is installed at the suction port of this invention, which can monitor the status of negative pressure monitoring in real time. This invention can control the suction head to swing in different directions by moving the control ring. When negative pressure suction is required at different positions, the main tube located in the vagina does not need to move, avoiding the discomfort caused by the rotation and movement of the main tube to the abortion patient. Only the head swings in different directions, completing the suction task at different positions while avoiding discomfort to the abortion patient. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0017] like Figures 1-4The illustration shows a suction aid device for abortion surgery, comprising an insertion tube 1 and a suction tube 2. The front end of the insertion tube 1 is inserted into the uterus for negative pressure suction. The suction tube 2 is connected to an external negative pressure device to provide negative pressure. The insertion tube 1 includes a suction head 3 and a main tube 4. The tail end of the main tube 4 has a tapered structure. The tail end of the main tube 4 is inserted into the head end of the suction tube 2, thus making the main tube 4 and the suction tube 2 detachably connected. The suction tube 2 is made of soft rubber. The front end of the suction head 3 has a bent structure and a suction port 31 is provided on the suction head 3 for negative pressure suction to perform the abortion. A miniature camera 32 and a light source 33 are provided on the side of the suction port 31 on the suction head 3. The miniature camera 32 is used for observation. The suction port 31 is observed. The miniature light source 33 is used to assist the miniature camera 32 in observing the suction port 31. The suction head 3 and the main tube 4 are connected by a corrugated pipe 5. Pull ropes are connected to the four quadrant points at the tail of the suction head 3. There are four pull ropes in total, which are set in the four directions of up, down, left and right. The four pull ropes are inserted into the wall of the main tube 4 and come out from the rear end of the main tube 4. The rear end of the main tube 4 is connected to a fixing pipe. Four universal balls 9 are movably connected to the four directions of up, down, left and right of the fixing ring 7. The four universal balls 9 are fixedly connected to the control ring 8. The control ring 8 is connected to the pull ropes that are inserted. By moving the control ring 8 in different directions, the suction head 3 can be controlled to swing in different directions.

[0018] The specific implementation process is as follows: First, the suction tube 2 and the insertion tube 1 are connected by threads. The insertion tube 1 is inserted into the uterus of the person undergoing abortion through the vagina. The rear end of the main tube 4 is held, and the suction tube 2 is connected to an external negative pressure device to provide negative pressure, thereby sucking the tissue to be aborted from the suction port 31 and expelling it out of the body through the main tube 4 and the suction tube 2. When it is necessary to suction different positions in the uterus, there is no need to move or swing the main tube 4 significantly. Just hold the control ring 8 and pull the control ring 8 in different directions. Since the control ring 8 is connected to the rear end of the suction head 3 through four traction lines 6, swinging the control ring 8 in different directions can control the suction head 3 to swing in different directions, thereby suctioning different positions.

[0019] The above descriptions are merely embodiments of the present invention, and common technical solutions or characteristics known in the schemes are not described in detail here. For those skilled in the art, various modifications and improvements can be made without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
