Description

Technical Field

[0001] This utility model relates to the technical field of biopsy caps for gastroscopy biopsy ports, specifically to a biopsy cap for a gastroscopy biopsy port. Background Technology

[0002] Current gastroscopy biopsy portals typically have a cap with a lid. When not performing a biopsy, the lid is closed on the cap, providing a seal. During a biopsy, the lid is opened, and biopsy forceps are inserted through the biopsy channel on the cap. The stomach cavity has a certain pressure; during a biopsy, the biopsy suture passes through the cap into the stomach cavity, and the biopsy cap seals the established channel to prevent the upward flow of gas and fluid from the stomach. However, existing biopsy caps have poor sealing, leaving a large gap in the biopsy portal after the biopsy forceps are inserted. The biopsy sampling process is often lengthy and involves large movements. If the patient also experiences gastric contractions due to stimulation of the stomach wall, the contents of the digestive cavity are more likely to be ejected. Gas and fluid in the stomach cavity can easily spray out through the gap between the biopsy suture and the biopsy channel from the biopsy portal. This not only contaminates the instrument and the environment but also affects the operation, resulting in poor safety and inconvenience.

[0003] To address this issue, application number 201110248078.1 discloses a "biopsy cap for an endoscope," which improves the structure of the biopsy cap by incorporating a one-way valve inside. The valve opens when the biopsy instrument is inserted and closes when it is withdrawn. However, this solution only addresses the issue of closing the cap after the biopsy procedure; the one-way valve cannot completely seal the biopsy port during the procedure, and the problem of leakage during operation remains unresolved. Utility Model Content

[0004] The purpose of this invention is to provide a biopsy cap for a gastroscopy biopsy port to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a biopsy cap for a gastroscopy biopsy port, comprising a cap body, a cap cover at the upper end of the cap body, and the cap cover comprising three tightly overlapping circular pads, each circular pad being composed of several tightly fitted fan-shaped air cushions, the arc ends of the fan-shaped air cushions being fixedly connected to the cap body, and the bonding lines of the three layers of fan-shaped air cushions being evenly distributed on a horizontal plane.

[0007] As an improvement, the fan-shaped air cushion is a silicone air cushion with an internal air cavity.

[0008] As an improvement, the circular pad is composed of six closely fitted fan-shaped air cushions, and the bonding lines of the three layers of the fan-shaped air cushions are evenly distributed on the horizontal plane at an angle of twenty degrees.

[0009] The advantages of this invention compared to existing technologies are as follows: The cap is fitted over the biopsy port of the endoscope with the cap facing upwards. When a biopsy is required, the biopsy forceps are inserted directly into the first circular pad of the cap. The three fan-shaped air cushions are sequentially expanded from the center in a vortex-like manner. Because the bonding lines of adjacent layers are staggered, the gaps between the openings of each fan-shaped air cushion are tightly sealed by the adjacent fan-shaped air cushions (the interior of the fan-shaped air cushions is an air cavity, which enhances the sealing effect when they are squeezed together). This avoids leaving gaps in the biopsy port with the biopsy forceps. After the biopsy line connects with the biopsy channel, gas and fluid may spray out along the biopsy line, but this is blocked by the sealed cap. After the biopsy is completed, the biopsy forceps are withdrawn, and the three circular pads immediately rebound and return to their natural overlapping state while maintaining a sealed seal.

[0010] The biopsy cap of this gastroscopy biopsy port consists of three tightly overlapping circular pads, each composed of several closely fitting fan-shaped air cushions. This design prevents the biopsy forceps from leaving gaps in the biopsy port, ensuring a good seal during the biopsy process and effectively preventing the leakage of digestive gas and fluids. It is safe, hygienic, and convenient to use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of the embodiments of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance. The use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be perfectly horizontal, but can be slightly tilted.

[0023] This embodiment is combined with the appendix Figures 1 to 4 This paper provides a detailed description of a biopsy cap for a gastroscopy biopsy port.

[0024] This embodiment provides a biopsy cap for a gastroscopy biopsy port, comprising a cap body 1, with a cap cover at the upper end of the cap body 1. The cap cover comprises three tightly overlapping circular pads 3, each circular pad 3 being composed of several tightly fitted fan-shaped air cushions 4. The arc ends of the fan-shaped air cushions 4 are fixedly connected to the cap body 1, and the bonding lines 2 of the three layers of fan-shaped air cushions 4 are evenly distributed on a horizontal plane.

[0025] The fan-shaped air cushion 4 is a silicone air cushion with an air cavity inside.

[0026] The circular pad 3 is composed of six closely fitted fan-shaped air pads 4, and the bonding lines 2 of the three layers of fan-shaped air pads 4 are evenly distributed on the horizontal plane at an angle of twenty degrees.

[0027] In practice, the cap 1 is placed over the biopsy port of the endoscope, with the cap facing upwards. When a biopsy is required, the biopsy forceps are inserted directly into the first circular pad 3 of the cap. The three fan-shaped air cushions 4 are sequentially expanded from the center in a vortex-like manner. Because the bonding lines 2 of adjacent layers are staggered, the gaps between the openings of each fan-shaped air cushion 4 are tightly sealed by the adjacent fan-shaped air cushions 4 (the inside of the fan-shaped air cushions 4 is an air cavity, which enhances the sealing effect when they are squeezed together). This prevents the biopsy forceps from leaving gaps in the biopsy port. After the biopsy line connects with the biopsy channel, gas and fluid may spray out along the biopsy line, but this is blocked by the sealed cap. After the biopsy is completed, the biopsy forceps are withdrawn, and the three circular pads 3 immediately rebound and return to their natural overlapping state while maintaining a sealed seal.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the actual scope of protection is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this invention should be included within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the scope of the claims.
