Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically to a suction-functional lumen used in conjunction with a hysteroscopic sheath. Background Technology

[0002] Modern hysteroscopic abortion surgery requires first opening the woman's vagina with a speculum, then inserting the hysteroscope through the vagina and cervix into the uterus to form an operating platform. The light source and camera system at the tip of the hysteroscope allow for direct visualization of the uterus, and the doctor then uses abortion instruments to remove the embryo.

[0003] After embryo removal, residual embryonic tissue may remain in the uterus. This tissue may continue to grow and affect endometrial repair, leading to a series of complications. Therefore, to avoid such residual villi, repeated hysteroscopic insertion and removal of the uterus are required to check for any remaining tissue and to use an external aspirator to remove the residual tissue. This significantly increases the risk of complications such as cervical laceration, uterine perforation, postoperative intrauterine adhesions, and cervical adhesions, and therefore needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lumen with suction function that is used in conjunction with a hysteroscopic sheath, thereby reducing the frequency of hysteroscopic instrument insertion and removal, improving surgical efficiency, and reducing surgical risks and complications.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A suction-functional lumen for use with a hysteroscopic sheath includes a tube body, wherein a suction channel is formed along the length of the tube body and a suction end is formed at the front end of the tube body, and a trumpet-shaped suction unit is connected to the front end of the tube body. The suction unit is made of an elastic material, and a sliding structure is formed between the suction unit and the tube body. The sliding structure is used to allow the suction unit to slide relative to the axis of the suction channel.

[0007] As a further improvement of this utility model, the sliding structure includes an installation groove provided on the inner wall of the suction end, the end of the suction unit extends outward to form a connecting part, the end of the connecting part away from the suction unit forms a limiting ring, the limiting ring is slidably connected to the installation groove, and the end of the limiting groove is provided with a limiting surface corresponding to the limiting ring, the limiting surface is used to abut against the limiting ring to prevent the limiting ring from falling out of the installation groove.

[0008] As a further improvement of this utility model, the limiting ring is made of magnetic material, and the end of the limiting groove away from the limiting surface is provided with a driving ring that repels the limiting ring. The driving ring is used to drive the limiting ring to move towards the limiting surface.

[0009] As a further improvement of this utility model, the attraction unit is provided with multiple reinforcing ribs in the circumferential direction.

[0010] As a further improvement of this utility model, one end of the reinforcing rib extends out of the suction unit to form a contact end, and a water inlet section is formed between adjacent contact ends.

[0011] As a further improvement of this utility model, the attraction unit is made of transparent material.

[0012] The beneficial effects of this utility model are:

[0013] 1. The funnel-shaped suction unit allows for a larger suction area at the front end of the tube, thereby improving the suction effect;

[0014] 2. The flexible suction unit can be folded to reduce its size, making it easier to enter the uterus through the hysteroscope. At the same time, the flexible suction unit can also ensure flexible contact with the uterine wall, thereby improving the safety of use.

[0015] 3. The sliding structure provides a certain range of motion for the attraction unit, which, combined with the elastic material of the attraction unit, further enhances safety performance.

[0016] 4. The elastic attraction unit can improve the attraction effect on the down at different positions and angles through its own deformation. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0021] like Figure 1-2 As shown, a suction-functional lumen for use with a hysteroscopic sheath includes a tube body 1. The tube body 1 forms a suction channel 2 along its length and a suction end is formed at the front end of the tube body 1. A trumpet-shaped suction unit 3 is connected to the front end of the tube body 1. The suction unit 3 is made of elastic material. A sliding structure 4 is formed between the suction unit 3 and the tube body 1. The sliding structure 4 is used to allow the suction unit 3 to slide relative to the axis of the suction channel 2.

[0022] In use, the suction unit 3 is folded and enters the uterus through the instrument channel of the hysteroscope via the tube 1. After entering the uterus, the suction unit 3 automatically opens under the action of elasticity to form a trumpet shape. The suction device is then connected to the rear end of the tube 1 to provide negative pressure to the tube 1. This suction device is existing technology and will not be described in detail here. It works in conjunction with the extension and retraction of the tube 1 and the movement of the hysteroscope to complete the suction of the chorionic villi in the uterus.

[0023] Due to the elasticity of the suction unit 3, it can naturally deform after contacting the human body, thereby ensuring flexible contact with the uterine wall and ensuring safety.

[0024] Meanwhile, when the operator moves the tube 1 too much, the sliding structure 4 can be used to slide the suction unit 3, thereby further improving safety and allowing the tube 1 to have a certain safe range of movement.

[0025] More specifically, the suction unit 3 is made of silicone to ensure flexibility in contact with the human body.

[0026] Preferably, the sliding structure 4 includes an installation groove 5 provided on the inner wall of the suction end. The installation groove 5 is specifically annular. The end of the suction unit 3 extends outward to form a connecting part 6. The end of the connecting part 6 away from the suction unit 3 forms a limiting ring 7. The limiting ring 7 is slidably connected to the installation groove 5. The end of the limiting groove is provided with a limiting surface 8 corresponding to the limiting ring 7. The limiting surface 8 is used to abut against the limiting ring 7 to prevent the limiting ring 7 from falling out of the installation groove 5.

[0027] The setting of the limiting ring 7, together with the limiting surface 8, can prevent the attraction unit 3 and the tube body 1 from separating, thereby ensuring the stability of the connection between the two.

[0028] Preferably, since the limiting ring 7 will move towards the rear end of the tube body 1 under the influence of negative pressure attraction, thereby affecting the safety range of the tube body 1, the limiting ring 7 is made of magnetic material, and a driving ring 9 that is repelled by the limiting ring 7 is provided at the end of the limiting groove away from the limiting surface 8. The driving ring 9 is used to drive the limiting ring 7 to move towards the limiting surface 8.

[0029] The magnetic drive mechanism allows for a more compact overall structure, reducing the impact on the size of the attraction channel 2.

[0030] Meanwhile, the magnetic drive method can always ensure the driving force on the limiting ring 7, so as to ensure the installation and movement range of the tube body 1.

[0031] Preferably, the attraction unit 3 is provided with a plurality of reinforcing ribs 10 in the circumferential direction. Specifically, the attraction unit 3 is an elastic film.

[0032] The reinforcing ribs 10 provide support for the attraction unit 3, enabling the attraction unit 3 to rebound quickly and thus ensuring the funnel-shaped attraction effect.

[0033] Because a lot of blood is produced after the embryo is removed, and the uterus is also flushed during the procedure using a hysteroscope, in order to ensure the suction field of the procedure, one end of the reinforcing rib 10 extends out of the suction unit 3 to form a contact end 11, and a water inlet zone 12 is formed between adjacent contact ends 11.

[0034] The water inlet section 12 allows the rinsing fluid entering the uterus along the hysteroscope to enter the suction channel 2, thereby guiding the water flow and cleaning the inner and outer walls of the suction unit 3 to a certain extent, so as to avoid blood residue on the side wall of the suction unit 3 and thus prevent poor observation.

[0035] Preferably, the attraction unit 3 is made of a transparent material.

[0036] The transparent suction unit 3, in conjunction with the water inlet section 12, allows operators to have a direct view of the suction area, facilitating operation.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
