A gastroscopy connector assembly

Abstract

This invention discloses a gastroscopy connector assembly, including a suction tube with ports at both ends. A fixing sleeve is fixedly installed on the inner wall of each port, and a support sleeve is fixedly installed on the inner wall of the port, located on one side of the fixing sleeve. The fixing sleeve includes an inclined surface, the end of which is fixedly installed to the inner wall of the port. The inclined surface gradually expands in an involute shape from the port opening inwards, and a first arc surface is formed on one side of the inclined surface. By using the fixing sleeve and support sleeve, the operator vertically inserts the external connecting tube from the gastroscopy endoscope into the port of the suction tube. During insertion, the inclined surface guides the tube, allowing it to gradually penetrate deeper into the port. The two sets of arc surfaces (first and second arc surfaces) form a wave-like structure to pre-tighten the external connecting tube, preventing it from easily loosening after being fitted into the port.

Description

Technical Field

[0001] This invention relates to the field of endoscope connector technology, specifically to an endoscope connector assembly. Background Technology

[0002] An external aspiration connection tube is a medical device used to drain secretions, foreign objects, blood, etc. from the body. It is usually composed of a catheter, a connecting tube, a suction bottle, a suction pump, etc. It can be divided into various types such as chest drainage tubes, abdominal drainage tubes, bile duct drainage tubes, and gastrointestinal drainage tubes. Among them, there is a suction tube connector for gastroscopy. One end connects to the endoscope on the gastroscope, and the other end connects to the negative pressure suction device. It is a disposable consumable, made entirely of medical-grade plastic material, and provides sterile use.

[0003] When using existing endoscope connectors, since the suction tube is for single use, no additional fixing components are provided at both ends of the suction tube during installation and use. This leads to excessive movement between the suction tube and the endoscope, which can cause the suction tube interface to loosen, affecting the normal drainage process. At the same time, the interface of the suction tube is also prone to leakage due to poor contact, causing instrument contamination and other problems. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a gastroscopy connector assembly. This assembly solves the problems of existing gastroscopy connectors where, because the suction tube is for single use, no additional fixing components are provided at both ends of the suction tube during installation. This results in excessive movement between the suction tube and the gastroscope, causing the suction tube interface to loosen and affecting subsequent drainage operations. Furthermore, the suction tube interface is prone to leakage due to poor contact, leading to contamination.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a gastroscopy connector assembly, including a suction tube, with ports installed at both ends of the suction tube. A fixing sleeve is fixedly installed on the inner wall of the port, and a support sleeve is fixedly installed on the inner wall of the port and on one side of the fixing sleeve. The fixing sleeve includes an inclined surface, the end of which is fixedly installed to the inner wall of the port. The inclined surface gradually expands in an involute shape from the port opening to the interior. A first arc surface is formed on one side of the inclined surface, and a second arc surface is formed at the other end of the first arc surface. The highest points of the arcs of the first and second arc surfaces are located on the same horizontal plane. A concave gap is formed between the first and second arc surfaces. The support sleeve includes an arc-shaped surface, with a fixing base formed at the bottom of the arc-shaped surface. An arc-shaped protrusion is integrally formed on the surface of the fixing base and near the inner side of the arc-shaped surface. The arc-shaped surface and the fixing base are L-shaped as a whole, and the outer side of the arc-shaped surface is in close contact with the outer side of the second arc surface. The tail end of the second arc surface is flush with the tail end of the arc-shaped surface.

[0008] Preferably, the diameter of the port is larger than the diameter of the suction tube, and the length of the port is between 1 cm and 3 cm.

[0009] Preferably, the connection between the fixing sleeve and the port is seamless, and both the fixing sleeve and the support sleeve are made of elastic plastic.

[0010] Preferably, the surfaces of the inclined surfaces are all smooth, and the joints between the inclined surfaces, the first arc surface, and the second arc surface are all seamlessly connected.

[0011] Preferably, the bulge direction of the first and second arc surfaces is perpendicular to the central axis direction of the port, and the tail end of the second arc surface is set as a semi-circle.

[0012] Preferably, the connection between the arc-shaped surface and the fixed base adopts a rounded corner transition design, and the protrusion direction of the arc-shaped protrusion points to the inside of the arc-shaped surface.

[0013] (III) Beneficial Effects

[0014] This invention provides a gastroscope connector assembly, which has the following advantages:

[0015] This invention, by setting a fixing sleeve and a support sleeve, allows the operator to vertically insert the external connecting tube of the gastroscope from the port of the suction tube. During insertion, the inclined surface guides the tube, gradually pushing it deeper into the port until the outer wall of the external connecting tube moves to the surface of the first and second arc surfaces. At this point, the external connecting tube applies pressure to the surfaces of the first and second arc surfaces, causing them to expand outwards. Finally, the surface of the external connecting tube comes into contact with the surfaces of the first and second arc surfaces, thus completing the fixation of the external connecting tube. The two sets of arc surfaces, forming a wavy structure, compress and pre-tighten the external connecting tube, making it less prone to loosening after it is fitted into the port. Furthermore, the wavy structure can form multiple fixing points to apply pressure to the surface of the external connecting tube, further improving its fixation and sealing effect.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] As attached Figure 1 To be continued Figure 6An endoscope connector assembly is shown, comprising a suction tube 1, with ports 2 installed at both ends of the suction tube 1. A fixing sleeve 3 is fixedly installed on the inner wall of the port 2, and a support sleeve 4 is fixedly installed on the inner wall of the port 2, located on one side of the fixing sleeve 3. The fixing sleeve 3 includes an inclined surface 31, the end of which is fixedly installed to the inner wall of the port 2. The inclined surface 31 gradually expands in an involute shape from the opening of the port 2 towards the interior. A first arc surface 32 is formed on one side of the inclined surface 31, and a second arc surface 33 is formed at the other end of the first arc surface 32. The highest points of the arcs of the first arc surface 32 and the second arc surface 33 are located on the same horizontal plane. A concave gap is formed between the first arc surface 32 and the second arc surface 33. The support sleeve 4 includes an arc surface 41. A fixed base 42 is formed at the bottom end of the arc surface 41. An arc protrusion 43 is integrally formed on the surface of the fixed base 42 and in the direction close to the inner side of the arc surface 41. The arc surface 41 and the fixed base 42 are L-shaped as a whole. The outer side of the arc surface 41 is in close contact with the outer side of the second arc surface 33. The tail end of the second arc surface 33 is flush with the tail end of the arc surface 41.

[0025] The diameter of port 2 is larger than the diameter of suction tube 1. The length of port 2 is between 1cm and 3cm. The connection between the fixing sleeve 3 and port 2 is seamless. Both the fixing sleeve 3 and the support sleeve 4 are made of elastic plastic. The surface of the inclined surface 31 is smooth. The connection between the inclined surface 31, the first arc surface 32 and the second arc surface 33 is seamless. The bulging direction of the first arc surface 32 and the second arc surface 33 is perpendicular to the central axis of port 2. The tail end of the second arc surface 33 is set as semi-circular.

[0026] Please refer to the attached instruction manual for details. Figure 5 The connection between the arc-shaped surface 41 and the fixed base 42 adopts a rounded corner transition design, and the protrusion direction of the arc-shaped protrusion 43 points to the inner side of the arc-shaped surface 41.

[0027] The specific implementation method is as follows: With the above configuration, it can be ensured that when the arc surface 41 is subjected to downward pressure from the second arc surface 33, the arc surface 41 can be supported and slightly deformed. During the deformation of the arc surface 41, the rounded corner position between the arc surface 41 and the fixed base 42 will deform synchronously. By using the arc protrusions 43 distributed on the side of the rounded corner position, the local stress at the rounded corner position between the arc surface 41 and the fixed base 42 can be reduced, thereby dispersing the local pressure and avoiding the occurrence of cracks between the arc surface 41 and the fixed base 42.

[0028] Working principle of the invention:

[0029] Step 1: First, the doctor inserts the entire gastroscopy device. The entire procedure of gastroscopy insertion is part of the existing surgical procedure and will not be described in detail here. As needed, the endoscope connected to the gastroscopy is fixed at port 2 of the suction tube 1.

[0030] Step Two: First, the operator vertically inserts the external connecting tube from the endoscope into port 2 of the suction tube 1. During insertion, the inclined surface 31 guides the tube, gradually pushing it deeper into port 2 until the outer wall of the external connecting tube moves to the surfaces of the first arc surface 32 and the second arc surface 33. At this point, pressure is applied to the surfaces of the first arc surface 32 and the second arc surface 33 through the external connecting tube, causing them to expand outwards. Finally, the surface of the external connecting tube makes contact with the surfaces of the first arc surface 32 and the second arc surface 33, thus completing the fixation of the external connecting tube. The two sets of arc surfaces 32 and 33 form a wavy structure to compress and pre-tighten the external connecting tube, making it less prone to loosening after it is fitted into port 2. Furthermore, the wavy structure can form multiple fixing points to apply pressure to the surface of the external connecting tube. The pressure further enhances its fixing effect. At the same time, during the outward expansion and deformation of the first arc surface 32 and the second arc surface 33, the arc surface 41 will be subjected to downward pressure from the second arc surface 33. At this time, the arc surface 41 can support it and undergo slight deformation itself, thereby avoiding excessive expansion of the tail end of the second arc surface 33 and preventing its tail end from pressing against the inner wall of the port 2, resulting in abnormal deformation. This makes the entire deformation process controllable. During the deformation of the arc surface 41, the rounded corner between the arc surface 41 and the fixed base 42 will deform synchronously. By using the arc protrusions 43 distributed on the side of the rounded corner, the local stress at the rounded corner between the arc surface 41 and the fixed base 42 can be reduced, thereby dispersing the local pressure and preventing cracks from forming between the arc surface 41 and the fixed base 42. Finally, the device completes the fixing operation of the external connecting pipe.

[0031] Step 3: After the surgery is completed, the external connecting tube is normally pulled out from port 2, and the entire suction tube 1 is disposed of as medical consumables.

[0032] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
