Description

Technical Field

[0001] This utility model relates to the field of biopsy tools, and in particular to a multifunctional biopsy connector assembly and biopsy device. Background Technology

[0002] To save on labor costs, most hospitals use fully automated endoscope cleaning and disinfection machines to clean endoscopes. The endoscope's operating handle has an endoscope biopsy port, primarily used for drug delivery and internal sampling. During endoscope cleaning and disinfection, the inside of the biopsy channel needs to be rinsed and disinfected. The endoscope connector is used to connect to the endoscope's biopsy port and to rinse and disinfect it.

[0003] Existing endoscope connectors are generally three-way connectors, with one port for securing the endoscope biopsy port, another for replacing the biopsy port, and a third for drug delivery. Too many ports can lead to the accumulation of impurities, causing hygiene problems, and are also inconvenient and costly. In other words, existing endoscope connectors primarily deliver drugs through a single port, but actual biopsies require the use of multiple fluids, such as saline and various functional drugs. Due to the different compositions and functions of these fluids, delivering different fluids through a single port requires frequent disassembly and reconnection of the tubing to other lines, thus requiring the connection of different lines to deliver different fluids. Furthermore, actual biopsies also require the introduction of carbon dioxide to dilate the patient's internal cavities, and a single port clearly cannot accommodate the delivery of different fluids. Therefore, the existing endoscope connectors suffer from a single fluid inlet, resulting in limited functionality and the need for frequent tubing changes. Utility Model Content

[0039] like Figure 1-4 A multifunctional biopsy connector assembly includes: an endoscope connector 1; the endoscope connector 1 is provided with a three-way body, one end of the main pipe of the three-way body is provided with a biopsy fixation port 11 for connecting to the endoscope biopsy port 01, the other end of the main pipe of the three-way body is provided with a connector biopsy port 12, and the three-way body is also provided with an irrigation port 13 in the manifold of the three-way body.

[0040] It also includes: a three-way valve 2, a medicine tube 3, a liquid-gas inlet tube 4, and a one-way valve 5;

[0041] The output end of the three-way valve 2 is connected to the infusion port 13, one of the input ends of the three-way valve 2 is connected to the output end of the medicine tube 3; the other input end of the three-way valve 2 is connected to the output end of the liquid-gas input tube 4, and the one-way valve 5 is installed on the liquid-gas input tube 4;

[0042] The input end of the medicine tube 3 is used to input medicine;

[0043] The input end of the liquid-gas input pipe 4 is used to input water and / or carbon dioxide.

[0044] This solution provides a multifunctional biopsy connector assembly, which is based on the structure of endoscope connector 1 with the addition of a three-way valve 2. By connecting the drug tube 3 and the liquid-gas input tube 4 at the input end of the three-way valve 2, and combining the advantages of the endoscope connector 1 itself, it can realize multiple functions such as biopsy, water injection, gas injection and drug injection, which solves the problems of the single function of the existing endoscope connector 1 and the need for frequent replacement of the tubing.

[0045] Specifically, the endoscope connector 1 has a known structure, comprising a three-way body; the main pipe of the three-way body is provided with a biopsy fixation port 11 and a connector biopsy port 12, and the manifold is provided with an irrigation port 13; a biopsy port is located on the endoscope's operating handle, and the biopsy fixation port 11 is used to install on the endoscope biopsy port 01, with the connector biopsy port 12 replacing the original endoscope biopsy port 01; the irrigation port 13 is located in the manifold of the three-way body and is used to connect to the output end of the three-way valve 2; and this solution installs the drug tube 3 and the liquid / gas input tube 4 at different input ends of the three-way valve 2, which can effectively expand the function of endoscopy. Therefore, it can perform multiple functions such as biopsy, water injection, gas injection, and drug injection. The three-way valve 2 has two input ends, which can be adjusted as needed to connect one of the input ends to the output end, thereby connecting the irrigation port 13 to the drug tube 3, or connecting the irrigation port 13 to the liquid-gas input tube 4. In this way, the drug tube 3 and the liquid-gas input tube 4 can be indirectly connected to the endoscope connector 1. The drug tube 3 is used to inject drugs, which can be drugs necessary for biopsy, such as anesthetics, cleaning solutions, etc.; the drugs can also be staining agents, which can assist in the use of the endoscope, thereby providing the endoscope connector 1 with the necessary function of temporary drug replenishment. The liquid-gas input tube 4 is used to inject water and / or carbon dioxide. When water is injected into the liquid-gas input tube 4, it can clean the lens to prevent blurring and contamination, and can also rinse internal organs to maintain a clear field of vision; the water is mainly physiological saline; while the gas injected into the liquid-gas input tube 4 is mainly carbon dioxide, which can expand the patient's internal visceral cavity to improve visibility and operating space. The one-way valve 5 on the liquid-gas inlet tube 4 controls the fluid in the liquid-gas inlet tube 4 to flow only towards the irrigation port 13, preventing fluid backflow and avoiding harm to the patient. Therefore, this solution can achieve multiple functions including biopsy, water injection, gas injection, and drug injection, solving the problem of the existing endoscope connector 1 having a single function and requiring frequent interface replacement.

[0046] Optimally, it also includes: a liquid-gas connector 6 and a temperature detection device 7;

[0047] The liquid-gas connector 6 is installed at the input end of the liquid-gas input pipe 4;

[0048] The liquid-gas connector 6 is provided with a fluid input channel 61; the output end of the fluid input channel 61 is connected to the input end of the liquid-gas input pipe 4; one input end of the fluid input channel 61 is used to input water, and the other input end of the fluid input channel 61 is used to input carbon dioxide.

[0049] The temperature detection device 7 is installed on the liquid-gas connector 6, and the detection end of the temperature detection device 7 is located in the fluid input channel 61.

[0050] The liquid-gas inlet pipe 4 can be directly or indirectly connected to the water and gas supply equipment. In the preferred embodiment, this solution uses a liquid-gas connector 6 installed at the inlet end of the liquid-gas inlet pipe 4. The liquid-gas connector 6 has a fluid inlet channel 61 inside, which can be used to introduce water and carbon dioxide. The fluid inlet channel 61 is connected to water or carbon dioxide through independent inlet ends, so water or carbon dioxide can be introduced into the endoscope connector 1 as needed. At the same time, this solution also uses the liquid-gas connector 6 as a carrier to install a temperature detection device 7 on the liquid-gas connector 6. The temperature detection device 7 is a known mechanism with temperature detection, which can detect the temperature of the fluid in the fluid inlet channel 61, which can prevent the water or carbon dioxide from being too hot when entering the endoscope connector 1, thereby avoiding harm to the patient.

[0051] Alternatively, the temperature detection device 7 may be equipped with a temperature display screen 71;

[0052] The temperature display screen 71 is located on the outer surface of the liquid-gas connector 6.

[0053] This solution can be equipped with a temperature display screen 71 on the temperature detection device 7, which can directly display the temperature value of the fluid input channel 61 on the outer surface of the liquid-gas connector 6, thereby facilitating the real-time acquisition of the temperature of the fluid input channel 61, making it easier to control the temperature of water and carbon dioxide entering the endoscope connector 1, and improving patient comfort.

[0054] Optimally, it also includes: a sound alarm module 8;

[0055] The sound alarm module 8 is installed on the temperature detection device 7; the sound alarm module 8 is communicatively connected to the temperature detection device 7.

[0056] The temperature detection device 7 can feed back the temperature of the fluid input channel 61 to the sound alarm module 8 in real time. Only a specific temperature range needs to be preset for the sound alarm module 8. If the temperature detected by the temperature detection device 7 exceeds the preset temperature range, the sound alarm module 8 can be activated, thereby feeding back to the inspector through sound and preventing the inspector from missing the opportunity to adjust the temperature.

[0057] The communication connection method here refers to the communication established between connected devices through signal transmission and interaction, which can be divided into wired connection and wireless connection; wired connection is such as conventional data cable connection; wireless connection is such as conventional WiFi, Bluetooth, infrared, NFC, etc.

[0058] Optimally, it also includes: filter structure 9;

[0059] The filter structure 9 is disposed at the input end of the medicine tube 3.

[0060] The filter structure 9 is located at the inlet end of the medicine tube 3 to isolate large-particle solid components in the medicine, prevent solid components from clogging the three-way valve 2, and further prevent the solid components from directly entering the endoscope connector 1.

[0061] Alternatively, the input and output ends of the three-way valve 2 can be fitted with removable end caps.

[0062] When the three-way valve 2 is not in use, the end cap can be used to seal the input and output ends of the three-way valve 2, which can improve the sealing degree of the three-way valve 2 and prevent impurities such as air dust from entering the three-way valve 2.

[0063] Optimally, the endoscope connector 1 is provided with a biopsy connection cover 15 with an internal thread structure; the outer side of the biopsy fixation port 11 is provided with an external thread structure; the biopsy fixation port 11 is threaded to the biopsy connection cover 15, and a sealing ring 14 for sealing the endoscope biopsy port 01 is provided inside the biopsy connection cover 15; the outer surface of the biopsy connection cover 15 is provided with a groove 16.

[0064] This design also includes a slot 16 on the biopsy connection cover 15 for easy disassembly and connection and to prevent detachment. After the endoscope biopsy port 01 can be quickly inserted into the slot 16, the biopsy connection cover 15 is rotated so that the endoscope biopsy port 01 presses against the sealing ring 14, sealing the endoscope biopsy port 01. The medicine can flow in from the irrigation port 13 and clean the endoscope biopsy port 01. The slot 16 not only makes the endoscope biopsy port 01 easy to disassemble and connect, but also ensures that the biopsy fixation port 11 will not fall off during the rinsing process, improving cleaning efficiency and saving time and cost.

[0065] A biopsy device includes: a liquid delivery and gas delivery integrated machine 10 and a multifunctional biopsy connector assembly according to any of the above embodiments;

[0066] The liquid delivery and gas delivery integrated machine 10 is respectively equipped with a medicine tank 101, a water storage tank 102 and a gas storage bottle 103;

[0067] The output end of the medicine tank 101 is connected to the input end of the medicine tube 3, and is used to output medicine to the medicine tube 3;

[0068] The output end of the water storage tank 102 is connected to the input end of the liquid-gas input pipe 4 for outputting water to the liquid-gas input pipe 4; and / or the output end of the gas storage cylinder 103 is connected to the input end of the liquid-gas input pipe 4 for outputting carbon dioxide to the liquid-gas input pipe 4.

[0069] This solution uses a liquid-gas delivery unit 10 in conjunction with a multi-functional biopsy connector assembly. A single liquid-gas delivery unit 10 simultaneously includes a reagent tank 101, a water tank 102, and a gas cylinder 103, capable of outputting reagents, water, and carbon dioxide to the reagent tube 3 and the liquid-gas input tube 4, respectively. This simplifies the structural complexity of the biopsy device, making it convenient for daily carrying and movement, for example, it can be placed on a mobile vehicle. Simultaneously, the liquid-gas input tube 4 can use a known adapter to connect to the water tank 102 and the gas cylinder 103, thereby receiving water from the water tank 102 and carbon dioxide from the gas cylinder 103. In the optimal embodiment, the liquid-gas input tube 4 connects to the water tank 102 and the gas cylinder 103 via the aforementioned liquid-gas connector 6.

[0070] Alternatively, the water tank 102 and the gas cylinder 103 are respectively provided with an electric heating and heat preservation device 104 and a temperature sensing device 105, and the electric heating and heat preservation device 104 is electrically connected to the temperature sensing device 105.

[0071] The biopsy device can activate the electric heating and insulation device 104 installed in the water tank 102 and the gas cylinder 103. The electric heating and insulation device 104 mainly heats the water tank 102 and the gas cylinder 103 by electric heating. A specific temperature range is preset in advance for the temperature sensing device 105. When the temperature of the water tank 102 or the gas cylinder 103 is lower than the preset value, the temperature sensing device 105 can activate the electric heating and insulation device 104 to heat the water tank 102 or the gas cylinder 103. For example, it can quickly heat the fluid to below 37 degrees Celsius, thereby improving the patient's comfort. When the temperature of the water tank 102 or the gas cylinder 103 is higher than the preset value, the temperature sensing device 105 can stop the heating of the electric heating and insulation device 104, thereby achieving the insulation effect of the water tank 102 and the gas cylinder 103.

[0072] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
