Abstract
Description
Technical fields:
[0002] This utility model belongs to the field of medical devices, and specifically relates to a disposable sterile protective sleeve for an ultrasound endoscope. Background technology:
[0004] With the advancement of endoscopic technology, the range of endoscopic procedures has expanded, and the use of endoscopic ultrasound (EUS) is increasing. EUS equipment includes the EUS main unit, the ultrasound actuator, and a small ultrasound probe (approximately 2.3 meters long and non-bendable) connected to the output of the ultrasound actuator. A complete EUS system typically costs over one million yuan, and even the small ultrasound probe alone costs over ten thousand yuan (70,000-80,000 yuan for domestically produced probes). Traditionally, during EUS examinations, the small ultrasound probe is suspended in mid-air near the instrument cart (used for placing and moving the EUS equipment) by passing its tip through a slot on the ultrasound actuator head. The probe is prone to hitting the edge of the instrument cart or accidentally falling to the ground, leading to contamination or damage to the tip, affecting its lifespan or rendering it unusable. Furthermore, movement by medical staff or moving the actuator can also contaminate the probe and actuator. The shortened lifespan or damage to the expensive small ultrasound probe increases medical costs. In addition, retrieving the small ultrasound probe from the ultrasound actuator slot is inconvenient, severely impacting the examination progress.
[0005] Currently, a Chinese patent titled "An Ultrasonic Sterile Protective Sheath with Dual Acoustic Shadow Positioning Function" (publication number CN214805346U) has been found. This patent includes a protective sheath body with an open end and a blind end. Two cords are attached to the protective sheath body, with one end on the body and the other end looping around the bottom and resting on the outer wall. This patent allows for precise location of the puncture site during ultrasound-assisted deep vein or arterial puncture and catheterization by simply covering the protective sheath with the cords. The position of the acoustic shadow generated by the cords can be adjusted during the puncture process to guide the acoustic shadow. After the puncture, the protective sheath can be removed directly. While this protective sheath is simple to operate, eliminating the need for manual cord binding to the ultrasound probe and offering high efficiency and speed, it does not provide adequate protection for the ultrasound driver and the small ultrasound probe, nor does it reduce the risk of damage to the small ultrasound probe. Summary of the Invention:
[0007] The purpose of this invention is to provide a disposable sterile protective sleeve for ultrasound endoscopes. This disposable sterile protective sleeve for ultrasound endoscopes is reasonably designed, which can reduce cross-infection between the small probe and the actuator of the ultrasound endoscope, improve the safety and efficiency of the examination, and at the same time be convenient to use and avoid impact damage to the expensive small probe.
[0008] This utility model relates to a disposable sterile protective sleeve for ultrasonic endoscopes, characterized in that it includes a sterile protective sleeve for a driver that is horizontally fitted around the periphery of the ultrasonic endoscope driver and a sterile protective sleeve for a small probe that is detachably connected to the sterile protective sleeve for the driver and located below the interface of the ultrasonic endoscope driver. The sterile protective sleeve for the small probe hangs naturally to accommodate the small probe of the ultrasonic endoscope. The openings of the sterile protective sleeve for the driver and the sterile protective sleeve for the small probe are close to each other, and the detachable connection between the sterile protective sleeve for the driver and the sterile protective sleeve for the small probe is close to the opening.
[0009] Furthermore, the aforementioned sterile protective sleeve for the actuator is cylindrical with openings at both its front and rear ends. Two detachable connectors that can be connected to each other are provided on both sides of its outer bottom. When the two opposing detachable connectors are connected, the sterile protective sleeve for the actuator can be narrowed to enclose the ultrasonic endoscope actuator.
[0010] Furthermore, the aforementioned sterile protective sleeve for the small probe is cylindrical, and an elastic filament is embedded along the edge of the opening of the sterile protective sleeve for the small probe. This elastic filament can expand the opening of the sterile protective sleeve for the probe into a circular shape.
[0011] Furthermore, the outer surface of the sterile protective sleeve for the aforementioned small probe is provided with an accessory bag for storing the safety sleeve and accessories for installing the ultrasonic water balloon.
[0012] Furthermore, the accessory bag is connected to the sterile protective sleeve of the small probe via a detachable connector, or the accessory bag is directly fixed to the outer surface of the sterile protective sleeve of the small probe.
[0013] Furthermore, the aforementioned detachable connectors are Velcro or nylon snap fasteners.
[0014] Furthermore, the detachable connection between the aforementioned sterile protective sleeve of the actuator and the sterile protective sleeve of the small probe is achieved through Velcro or nylon snap fasteners.
[0015] Furthermore, the sterile protective sleeve for the aforementioned endoscopic ultrasound probe is 25*40 cm in size when it is cylindrical, the sterile protective sleeve for the actuator is 15*30 cm in size when it is tubular, and the accessory bag is 12*12 cm in size when it is closed and rectangular.
[0016] Furthermore, the edge of the opening of the sterile protective sleeve for the small probe has an annular channel, the elastic filament is inserted into the annular channel, and a tightening rope is also provided in the annular channel to reduce the diameter of the elastic filament and the opening of the sterile protective sleeve for the small probe after the tightening rope is tightened.
[0017] Furthermore, the aforementioned sterile protective sleeves for the actuator and the small probe are made of medical sterile cloth material.
[0018] The method of using the disposable sterile protective sleeve for ultrasound endoscopes of this utility model involves placing the sterile protective sleeve of the cylindrical actuator onto the ultrasound endoscope actuator. The sleeve is then secured and narrowed using Velcro (detachable connectors) on both sides of the bottom. The sterile protective sleeve for the small probe is vertically suspended below the interface of the ultrasound endoscope actuator, thus preventing the small probe from slipping off and avoiding cross-infection between the small probe and the ultrasound endoscope actuator, improving the safety and efficiency of the examination. It also prevents damage to the expensive small probe due to impact from movement of the ultrasound endoscope actuator or treatment cart, which would increase medical costs. The safety sleeve and accessories for the ultrasound water balloon can be placed in the accessory bag for easy access and to prevent loss. After the ultrasound endoscope operation is completed, the disassembled small probe can be placed directly inside the sterile protective sleeve. The sterile protective sleeve for the small probe can be removed by tearing off the Velcro (detachable connectors) and sent directly to the cleaning and disinfection room for cleaning and disinfection, avoiding cross-infection and damage from impact caused by manually transporting the small probe to the cleaning and disinfection room.

[0030] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.
[0031] This utility model includes a disposable sterile protective sleeve for an ultrasonic endoscope, comprising a sterile protective sleeve 2 for the driver 1, which is horizontally fitted around the ultrasonic endoscope driver 1, and a sterile protective sleeve 3 for a small probe, which is detachably connected to the sterile protective sleeve for the driver and located below the interface of the ultrasonic endoscope driver. The sterile protective sleeve for the small probe hangs down naturally to accommodate the small probe 4 of the ultrasonic endoscope (the small probe 4 of the ultrasonic endoscope is a 2.3-meter thin cable). The openings of the sterile protective sleeves for the driver 2 and the sterile protective sleeve for the small probe are close to each other, and the detachable connection between the sterile protective sleeve for the driver and the sterile protective sleeve for the small probe (i.e., connected by a first detachable connector 10, which can be Velcro or a nylon snap) is close to the opening.
[0032] The sterile protective sleeve 2 for the actuator is cylindrical with openings at both ends. Two or three detachable connectors 5 are located on each side of its outer bottom circumference (i.e., two or three detachable connectors 5 are located at 60-90 degree intervals along the circumference of the cylindrical sterile protective sleeve 2, and the detachable connectors 5 are also spaced apart axially). The detachable connectors 5 are Velcro or nylon snap fasteners. When two oppositely positioned detachable connectors are connected (i.e., between the circumferences...),... (The sterile protective sleeve of the driver can be narrowed and folded by using Velcro at 60-90 degrees or fastening with nylon buttons) Even if the diameter of the round tube is reduced, it can achieve the wrapping of the ultrasonic endoscope driver. (When the two detachable connectors 5 are not glued, the diameter of the sterile protective sleeve 2 of the driver is larger, which makes it easier for the sterile protective sleeve 2 of the driver to be put on the outside of the ultrasonic endoscope driver 1. When the two detachable connectors are connected, the sterile protective sleeve of the driver is narrowed and folded, which helps to tighten the ultrasonic endoscope driver 1 and avoid contamination.)
[0033] Figure 3 This is a bottom view schematic diagram of the sterile protective cover for the actuator. Figure 3 The two upper Velcro straps are rough-surfaced, and the two lower Velcro straps are hook-surfaced. When the upper and lower hook-surfaced or rough-surfaced Velcro straps are attached together, the drive unit can be narrowed and folded. (Standard protective sleeve 2) Figure 3 The two first detachable connectors 10 (Velcro) on the right side are both rough-surfaced, while the Velcro at the opening of the small probe sterile protective sleeve 3 is hook-surfaced, thereby achieving the bonding between the driver sterile protective sleeve 2 and the small probe sterile protective sleeve 3.
[0034] The small probe sterile protective sleeve 3 is cylindrical, and an elastic thread 6 (the elastic thread 6 is a commercially available component, namely an arc-shaped elastic metal or plastic strip, which can shrink or expand its diameter when subjected to radial external force and return to its original shape after the external force is removed) is embedded along the edge of the sleeve opening. This elastic thread can open the sleeve opening into a circular shape (for easy removal and placement of the small probe); that is, the edge of the sleeve opening has an annular channel 7 (made by the sleeve opening). The elastic thread 6 is formed by bending the fabric in the opposite direction and sewing it together. It is inserted into the annular channel 7. A tightening rope 8 is also provided in the annular channel to reduce the diameter of the elastic thread and the opening of the sterile protective sleeve of the small probe after the tightening rope is tightened. The tightening rope 8 is a commercially available component, which is a rope inserted into the annular channel 7. The two ends of the rope that go out of the annular channel 7 are connected by a rope stop buckle 11 so that when the rope stop buckle is pulled, the elastic thread 6 is subjected to radial external force and its diameter is reduced, which also reduces the opening.
[0035] When the small probe 4 of the ultrasound endoscope needs to be placed in the sterile protective sleeve 3, the tightening rope 8 and the rope stop buckle are not tightened, so that the elastic thread opens the opening of the sterile protective sleeve of the probe into a round shape, making it convenient to put the small probe 4 of the ultrasound endoscope into the sleeve; when the small probe 4 of the ultrasound endoscope needs to be disinfected during transfer, the sterile protective sleeve 3 of the small probe is separated from the sterile protective sleeve 2 of the driver, and the opening is tightened by the tightening rope 8 and the rope stop buckle to prevent contamination during the transfer process.
[0036] For a reasonable design, the outer surface of the sterile protective sleeve 3 of the small probe is provided with an accessory bag 9 for storing the safety sleeve and accessories for installing the ultrasonic water balloon; the accessory bag 9 is also connected to the sterile protective sleeve of the small probe by a detachable connector (Velcro or nylon snap fastener), or the accessory bag is directly fixed to the outer surface of the sterile protective sleeve of the small probe; in addition, the inner wall of the accessory bag 9 can also be provided with Velcro that can be glued to each other, so that the safety sleeve and accessories of the ultrasonic water balloon in the bag can be prevented from falling out after the inner wall of the accessory bag 9 is glued together.
[0037] The sterile protective sleeve for the aforementioned endoscopic ultrasound probe measures 25*40 cm when it is cylindrical, 15*30 cm when it is tubular, and 12*12 cm when the accessory bag is closed and rectangular.
[0038] The sterile protective sleeves for the actuator and the small probe can be made of medical sterile cloth material; or both the sterile protective sleeves for the actuator and the small probe can sequentially include an outer non-woven fabric layer, an absorbent layer, a waterproof layer, and an inner non-woven fabric layer, wherein the absorbent layer can be superabsorbent wood pulp fiber or superabsorbent polymer resin particles, etc., and the waterproof layer is a waterproof plastic film, etc.; the four edges of the outer non-woven fabric layer and the inner non-woven fabric layer are sewn and fixed, the waterproof layer and the inner non-woven fabric layer are glued together, and the absorbent layer is filled and laid between the outer non-woven fabric layer and the waterproof layer. The protective sleeve of this application is impermeable, absorbent, and biodegradable. The method of using the disposable sterile protective sleeve for ultrasound endoscopes of this utility model involves placing the sterile protective sleeve of the cylindrical actuator onto the ultrasound endoscope actuator. The sleeve is then secured and narrowed using Velcro (detachable connectors) on both sides of the bottom. The sterile protective sleeve for the small probe is vertically suspended below the interface of the ultrasound endoscope actuator, thus preventing the small probe from slipping off and avoiding cross-infection between the small probe and the ultrasound endoscope actuator, improving the safety and efficiency of the examination. It also prevents damage to the expensive small probe due to impact from movement of the ultrasound endoscope actuator or treatment cart, which would increase medical costs. The safety sleeve and accessories for the ultrasound water balloon can be placed in the accessory bag for easy access and to prevent loss. After the ultrasound endoscope operation is completed, the disassembled small probe can be placed directly inside the sterile protective sleeve. The sterile protective sleeve for the small probe can be removed by tearing off the Velcro (detachable connectors) and sent directly to the cleaning and disinfection room for cleaning and disinfection, avoiding cross-infection and damage from impact caused by manually transporting the small probe to the cleaning and disinfection room.
[0039] This utility model provides a disposable protective sleeve for small ultrasonic endoscope probes. It meets the usage characteristics of small ultrasonic endoscope probes, prevents cross-contamination between the probe and the driver, improves the safety and efficiency of the examination, and implicitly ensures the progress of the examination while controlling the examination time and cost. This utility model has a simple structure, is specifically designed for ultrasonic endoscopy, and is reasonable in design and easy to use.
[0040] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
