Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a probe device for an endoscope. Background Art

[0002] In the traditional diagnosis process of the digestive tract, the flexible endoscope of the digestive tract is the most important diagnostic tool. However, an ordinary endoscope can only observe the mucosal layer of the digestive tract, and cannot observe the submucosa or muscular layer under the digestive tract mucosa, resulting in poor detection effects. For some endoscopes equipped with ultrasonic probes, although the ultrasonic probe can perform real-time ultrasonic scanning after entering the patient's body through the operation channel of the endoscope to obtain the histological structure characteristics of the wall layers of the pipeline and the ultrasonic images of the surrounding adjacent organs, during this process, the assistance of an ultrasonic medium is required for the ultrasonic probe to achieve ultrasonic imaging; during the use of the ultrasonic probe, it is necessary to prevent the leakage of the ultrasonic medium and avoid the intrusion of impurities such as air into the ultrasonic medium. Therefore, in order to ensure the imaging effect, most of the existing probe components are disposable products, resulting in a high clinical use cost. Summary of the Invention

A limiting step is arranged on the inner wall of the first end of the probe barrel. The first seal is set as a sealing ring.

[0012] The first seal is sleeved on the first rotating shaft sleeve and is located between the limiting convex rail and the limiting step. The second end of the probe barrel abuts against the bottom wall of the placement cavity.

[0013] As a further technical solution, the sealing assembly includes a transition sleeve, a second seal and a third seal. Both the second seal and the third seal are set as sealing rings.

[0014] The transition sleeve is sleeved on the probe barrel. The second seal is sleeved on the transition sleeve and abuts against the inner wall of the placement cavity. The third seal is sleeved on the probe barrel and abuts against the inner wall of the placement cavity. The liquid inlet hole is located between the second seal and the third seal.

[0015] As a further technical solution, a first limiting groove extending along the circumferential direction of the transition sleeve is arranged on the transition sleeve. The second seal is arranged in the first limiting groove.

[0016] A second limiting groove extending along the circumferential direction of the probe barrel is arranged on the probe barrel. The third seal is arranged in the second limiting groove.

[0017] As a further technical solution, the imaging mechanism further includes a synchronous cable, an imaging component and a wire rotating cylinder. The imaging component is used for detecting information of a target position.

[0018] The first end of the wire rotating cylinder is connected to the second end of the first rotating shaft sleeve.

[0019] As a further technical solution, the endoscopic probe device also includes a rotating assembly, which includes a second rotating sleeve and a connector.

[0023] Compared with the prior art, the endoscope probe device provided by the present invention has the following technical advantages:

[0024] 1. Due to the sealed connection between the imaging mechanism and the sleeve assembly, a sealed accommodating chamber is formed between the imaging mechanism and the sleeve assembly, and a liquid inlet hole is provided on the side wall of the accommodating chamber; therefore, before the endoscope is used, the liquid inlet hole is opened, and the ultrasonic medium is poured into the accommodating chamber through the liquid inlet hole, and then the liquid inlet hole is closed to seal the accommodating chamber. When the endoscope is used later, on the one hand, the imaging mechanism is immersed in the ultrasonic medium to ensure the imaging effect of the imaging mechanism; on the other hand, the sealing of the accommodating chamber can prevent the leakage of the ultrasonic medium and prevent impurities such as air from entering the ultrasonic medium, so as to further improve the imaging effect of the imaging mechanism; thirdly, since the ultrasonic medium is in the sealed accommodating chamber, and the accommodating chamber is formed by the cooperation between the components on the probe mechanism, that is, the formation of the sealed accommodating chamber does not require the help of other components of the endoscope, so the probe mechanism can be recycled on the premise of ensuring its imaging effect, thereby reducing its use cost.

[0025] 2. With the help of the sealing assembly, a sealed cavity can be formed between the inner wall of the storage cavity and the sleeve assembly, and the liquid inlet hole is located in the sealed cavity. Therefore, during the use of the endoscope, even if the seal of the liquid inlet hole becomes loose, the sealed cavity can still seal the liquid inlet hole, thereby preventing the ultrasonic medium in the accommodating cavity from leaking out of the interface assembly, and also preventing air or impurities outside the interface assembly from entering the accommodating cavity, so as to further improve the overall sealing of the endoscope probe device.

It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] Combined with Figures 1 to 4 As shown, on the premise of ensuring the imaging effect, the probe device for an endoscope provided in this embodiment can be recycled, thereby reducing its use cost. Specifically, the probe device for an endoscope includes an interface component 100, a probe mechanism 200, and a sealing component 300: The interface component 100 is internally provided with an open-shaped storage cavity; the probe mechanism 200 includes an imaging mechanism 210 and a sleeve assembly 220. The sleeve assembly 220 is located in the storage cavity. The imaging mechanism 210 is hermetically connected to the sleeve assembly 220 and cooperates with the sleeve assembly 220 to form a storage cavity for accommodating an ultrasonic medium. A closable liquid inlet hole 202 is provided on the side wall of the storage cavity; the sealing component 300 is arranged between the inner wall of the storage cavity and the sleeve assembly 220 to form a sealing cavity between the inner wall of the storage cavity and the sleeve assembly 220, and the liquid inlet hole 202 is located in the sealing cavity.

[0041] Since there is a sealed connection between the imaging mechanism 210 and the sleeve assembly 220, a sealed accommodation cavity is formed between the imaging mechanism 210 and the sleeve assembly 220, and a liquid inlet hole 202 is provided on the side wall of the accommodation cavity. Therefore, before using the endoscope, the liquid inlet hole 202 is opened, and an ultrasonic medium is poured into the accommodation cavity through the liquid inlet hole 202, and then the liquid inlet hole 202 is sealed, so that the accommodation cavity is sealed. Then, when using the endoscope, on the one hand, the imaging mechanism 210 is immersed in the ultrasonic medium to ensure the imaging effect of the imaging mechanism 210; on the other hand, the accommodation cavity is sealed, which can prevent the ultrasonic medium from leaking and at the same time prevent impurities such as air from entering the ultrasonic medium, so as to further improve the imaging effect of the imaging mechanism 210; on the third hand, since the ultrasonic medium is in the sealed accommodation cavity, and the accommodation cavity is formed by the cooperation of the components on the probe mechanism 200, that is, the formation of the sealed accommodation cavity does not require the assistance of other components of the endoscope. Therefore, on the premise of ensuring its imaging effect, the probe mechanism 200 can be recycled, thereby reducing its use cost.

[0042] Since the sealing assembly 300 is used, a sealed cavity can be formed between the inner wall of the storage cavity and the sleeve assembly 220, and the liquid inlet hole 202 is located in the sealed cavity. Therefore, during the use of the endoscope, even if the seal of the liquid inlet hole 202 becomes loose, the sealed cavity can seal the liquid inlet hole 202, thereby preventing the ultrasonic medium in the accommodation cavity from leaking to the outside of the interface assembly 100, and also preventing air or impurities outside the interface assembly 100 from entering the accommodation cavity, so as to further improve the overall sealing performance of the probe device for endoscopes.

[0043] Furthermore, the sleeve assembly 220 includes a probe barrel 221, a sheath 222 and a first seal 223. An interface channel 101 is provided on the bottom wall of the storage cavity; the imaging mechanism 210 is inserted into the first end of the probe barrel 221 and is hermetically connected to the inner wall of the first end of the probe barrel 221 through the first seal 223. The first end of the sheath 222 is hermetically connected to the second end of the probe barrel 221, so that an accommodation cavity is formed between the imaging mechanism 210, the inner wall of the probe barrel 221 and the inner wall of the sheath 222. The second end of the sheath 222 is inserted into the interface channel 101 and extends outside the interface assembly 100, and the liquid inlet hole 202 is provided on the side wall of the probe barrel 221.

[0044] Specifically, the probe cylinder body 221 is arranged as a cylinder body with openings at both ends. The first end of the sheath tube 222 is hermetically connected to the second end of the probe cylinder body 221, and the second end of the sheath tube 222 is arranged as a closed end. The imaging mechanism 210 is inserted into the first end of the probe cylinder body 221, so as to form a receiving cavity between the imaging mechanism 210, the inner wall of the probe cylinder body 221 and the inner wall of the sheath tube 222. A first seal 223 is arranged between the imaging mechanism 210 and the inner wall of the first end of the probe cylinder body 221 to improve the sealing performance of the receiving cavity and prevent the ultrasonic medium filled into the receiving cavity from leaking, so as to provide a stable imaging environment for the imaging mechanism 210. When the imaging mechanism 210 is inserted into the first end of the probe cylinder body 221, a part of the structure of the imaging mechanism 210 passes through the probe cylinder body 221 and extends into the second end of the sheath tube 222, so as to facilitate ultrasonic imaging of the target position through the sheath tube 222. Since the diameter of the probe cylinder body 221 is larger than that of the sheath tube 222, the liquid inlet hole 202 is arranged on the side wall of the probe cylinder body 221, which can reduce the processing difficulty of the liquid inlet hole 202 and can maximize the diameter of the liquid inlet hole 202, thereby improving the convenience of adding the ultrasonic medium through the liquid inlet hole 202. To ensure the use effect of the liquid inlet hole 202, a waterproof screw (not marked in the figure) is provided. By loosening the waterproof screw, the ultrasonic medium can be filled into the receiving cavity through the liquid inlet hole 202. By tightening the waterproof screw, the liquid inlet hole 202 is completely blocked, so as to ensure the sealing performance of the receiving cavity.

[0045] In addition, in this embodiment, the interface assembly 100 includes an interface cylinder body 110 and an interface cover body 120. The interface cover body 120 covers the second end of the interface cylinder body 110 and is hermetically arranged with the second end of the interface cylinder body 110, so that the interface cylinder body 110 and the interface cover body 120 cooperate to form an object placing cavity. By arranging the interface cylinder body 110 and the interface cover body 120 separately, the convenience of installing the probe mechanism 200 in the object placing cavity is improved. The interface channel 101 is arranged on the interface cover body 120, and the axis of the interface channel 101 is concentric with the axis of the object placing cavity to ensure the use effect of the probe mechanism 200 arranged in the object placing cavity. And to improve the sealing effect, the outer wall of the sheath tube 222 abuts against the inner wall of the interface channel 101.

[0046] Furthermore, in this embodiment, a waterproof cap 500 is also provided, and the waterproof cap 500 is covered on the first end of the interface cylinder 110, so that the entire storage cavity is in a sealed state, so that the endoscope probe device can achieve an overall waterproof effect. In this state, the endoscope probe device can be sterilized without damaging the internal structure, thereby achieving the reuse of the entire device. In order to ensure the installation convenience and waterproof effect of the waterproof cap 500, in this embodiment, the waterproof cap 500 is made of silicone or rubber material; in order to avoid the waterproof cap 500 from being lost in a non-sterilized state, in this embodiment, the waterproof cap 500 is connected to the outer wall of the interface assembly 100 through a flexible connector (not shown in the figure).

[0047] Preferably, the imaging mechanism 210 includes a first rotating sleeve 211, a limiting convex rail 2111 is provided on the outer wall of the first rotating sleeve 211, a limiting step 2211 is provided on the inner wall of the first end of the probe cylinder 221, and the first sealing member 223 is provided as a sealing ring; the first sealing member 223 is sleeved on the first rotating sleeve 211 and is located between the limiting convex rail 2111 and the limiting step 2211, and the second end of the probe cylinder 221 abuts against the bottom wall of the storage cavity.

[0048] Specifically, the limiting convex rail 2111 and the limiting step 2211 both extend in a ring shape along the circumference of the probe barrel 221. When the imaging component 213 is connected to the first end of the probe barrel 221, a limiting groove is formed between the limiting convex rail 2111 and the limiting step 2211. At this time, the sealing ring is sleeved on the first rotating sleeve 211, located in the limiting groove, and abuts against the inner wall of the probe barrel 221; in this way, the sealing effect between the imaging component 213 and the probe barrel 221 is ensured; at the same time, the relative position of the first sealing component 223 is limited by the limiting groove to avoid leakage of the accommodating chamber due to displacement of the first sealing component 223 as the use time increases. Furthermore, the imaging mechanism 210 further includes a limiting seat 215, on which a connecting through hole is provided, and the limiting seat 215 is sleeved on the first rotating sleeve 211 through the limiting through hole, and is located on the side of the limiting convex rail 2111 away from the limiting step 2211, and the outer peripheral wall of the limiting seat 215 abuts against the inner wall of the probe cylinder 221, so as to limit the relative position of the imaging mechanism 210 and the probe cylinder 221, thereby further limiting the relative position of the first sealing member 223 between the imaging mechanism 210 and the probe cylinder 221. The second end of the probe cylinder 221 abuts against the bottom wall of the storage cavity to avoid a gap between the probe cylinder 221 and the interface cover 120, which causes a waste of space in the storage cavity.

[0049] In addition, in order to further enhance the sealing effect between the imaging assembly 213 and the probe barrel 221, a plurality of first sealing members 223 are arranged at intervals in the limiting groove.

[0050] Preferably, the sealing assembly 300 includes a transition sleeve 310, a second seal 320, and a third seal 330. Both the second seal 320 and the third seal 330 are arranged as sealing rings. The transition sleeve 310 is sleeved on the probe cylinder body 221. The second seal 320 is sleeved on the transition sleeve 310 and abuts against the inner wall of the placement cavity. The third seal 330 is sleeved on the probe cylinder body 221 and abuts against the inner wall of the placement cavity. Thus, a sealing cavity is formed between the probe mechanism 200 and the interface assembly 100. The liquid inlet hole 202 is located between the second seal 320 and the third seal 330, that is, the liquid inlet hole 202 is located in the sealing cavity. With such an arrangement, secondary sealing of the accommodation cavity is achieved. During the use of the probe device for an endoscope, even if the waterproof screw becomes loose, the sealing cavity can seal the liquid inlet hole 202, thereby preventing the ultrasonic medium in the accommodation cavity from leaking outside the interface assembly 100.

[0051] Furthermore, a first limiting groove 311 extending along the circumferential direction of the transition sleeve 310 is provided on the transition sleeve 310, and the second seal 320 is arranged in the first limiting groove 311. A second limiting groove 2212 extending along the circumferential direction of the probe cylinder body 221 is provided on the probe cylinder body 221, and the third seal 330 is arranged in the second limiting groove 2212.

[0052] In this embodiment, both the second seal 320 and the third seal 330 are arranged as flexible sealing rings. By providing the first limiting groove 311 and the second limiting groove 2212, the relative positions of the second seal 320 and the third seal 330 in the axial direction of the interface cylinder body 110 are restricted, avoiding the situation of liquid leakage in the sealing cavity caused by the displacement of the second seal 320 and the third seal 330 over time. And because both the second seal 320 and the third seal 330 are arranged as flexible sealing rings, the flexible sealing rings can be adaptively compressed according to the actual situation of the inner wall of the placement cavity to further improve the sealing effect of the sealing cavity.

[0053] In some other embodiments, the transition sleeve 310 may not be provided, and the first limiting groove 311 and the second limiting groove 2212 are directly arranged at intervals on the outer peripheral wall of the probe cylinder body 221. By arranging flexible sealing rings in the limiting grooves, a sealing cavity is formed between the outer wall of the probe cylinder body 221 and the inner wall of the placement cavity. Or, a third limiting groove in a ring shape is directly provided on the outer peripheral wall of the probe cylinder body 221, a fourth seal is arranged in the third limiting groove, and the liquid inlet hole 202 is arranged inside the third limiting groove, thereby forming a sealing cavity between the outer wall of the probe cylinder body 221 and the inner wall of the placement cavity.

[0054] Preferably, the imaging mechanism 210 further includes a synchronous cable 212, an imaging component 213, and a wire rotating cylinder 214. The imaging component 213 is used to detect information of the target position. The first end of the wire rotating cylinder 214 is connected to the second end of the first rotating sleeve 211. The imaging component 213 is disposed at the second end of the wire rotating cylinder 214. The synchronous cable 212 is inserted into the first end of the first rotating sleeve 211 and extends into the wire rotating cylinder 214 to communicate with the imaging component 213. When the imaging mechanism 210 is connected to the probe cylinder 221, the second end of the wire rotating cylinder 214 passes through the probe cylinder 221 and extends into the second end of the sheath tube 222, and the imaging component 213 is disposed at the second end of the wire rotating cylinder 214, so as to perform ultrasonic imaging on the target position through the sheath tube 222. The synchronous cable 212 is used to transmit the information of the target position detected by the imaging component 213 to an external receiving mechanism. By rotating the first rotating sleeve 211, the wire rotating cylinder 214 and the imaging component 213 are driven to rotate, so as to change the imaging area of the imaging component 213, thereby further improving the imaging effect during ultrasonic imaging of the target position. In this embodiment, the synchronous cable 212 is preferably made of a material with high torque and good flexibility, and the wire rotating cylinder 214 is set as a braided tube with better transmission torque. In addition, the imaging component 213 can adopt an existing ultrasonic imaging structure, which will not be elaborated here.

[0055] Preferably, the endoscopic probe device further includes a rotating assembly 400. The rotating assembly 400 includes a second rotating sleeve 410 and a plug-in member 420. The second rotating sleeve 410 is drivingly connected to the first rotating sleeve 211. The plug-in member 420 is inserted into the second rotating sleeve 410 and communicatively connected to the synchronous cable 212.

[0056] The plug-in member 420 is drivingly connected to an external rotating mechanism (not shown in the figure) and is drivingly connected to the first rotating sleeve 211 through the second rotating sleeve 410, so as to realize the rotation of the imaging mechanism 210 driven by the external rotating mechanism, thereby completing the ultrasonic scanning of the target position. The plug-in member 420 is communicatively connected to the synchronous cable 212. The imaging component 213 transmits the information of the scanned target position to the external receiving mechanism through the synchronous cable 212 and the plug-in member 420, so that the operator can timely and accurately master the specific information of the target position.

[0057] Further, the probe device for an endoscope further includes a PCB calibration component 430. An avoidance groove is provided on the inner wall of the second rotary sleeve 410. The PCB calibration component 430 is located in the avoidance groove, and the PCB calibration component 430 is arranged between the connector 420 and the synchronization cable 212 to adjust the signal transmitted by the imaging component 213. Since the information scanned by the imaging component 213 is transmitted in the form of a wave signal, the signal will weaken during the transmission process, resulting in a poor final imaging display effect and causing deviation in the operator's grasp of the information of the target position. To avoid this situation, in this embodiment, the PCB calibration component 430 is arranged between the connector 420 and the synchronization cable 212. The PCB calibration component 430 can adjust the intensity of the transmitted signal by fine-tuning, increase the echo signal of the imaging component 213, thereby enhancing the information transmitted to the external receiving mechanism, and further improving the image quality of the image formed on the external receiving mechanism, so as to improve the accuracy of the operator's grasp of the information of the target position. And the PCB calibration component 430 is arranged in the avoidance groove to ensure its signal enhancement effect while avoiding interference with the second rotary sleeve 410.

[0058] Preferably, the probe device for an endoscope further includes a PCB protection component 440. The PCB protection component 440 is arranged in the avoidance groove, and the PCB protection component 440 is made of a metal material.

[0059] Since an avoidance groove is provided on the inner wall of the second rotary sleeve 410, that is, a local hollowing is performed on the second rotary sleeve 410, during the process of driving the imaging mechanism 210 to rotate by the external rotating mechanism, this local hollowing will affect the dynamic balance of the second rotary sleeve 410 during rotation. In this embodiment, by arranging the metal material PCB protection component 440 in the avoidance groove, the dynamic balance of the second rotary sleeve 410 during rotation is ensured, and the vibration and noise during the rotation of the imaging mechanism 210 are reduced, the use stability of the second rotary sleeve 410 is improved, and the service life of the second rotary sleeve 410 is prolonged. In this embodiment, the PCB protection component 440 is made of copper. In some other embodiments, materials with a density similar to that of copper, such as iron and steel, can also be used.

[0060] Preferably, the rotating assembly 400 further includes a sensor 450. The sensor 450 is arranged on the inner wall of the second rotary sleeve 410 and is used to sense the movement condition of the connector 420.

[0061] Specifically, the sensing element disposed on the inner wall of the second rotating bushing 410 can record the self-structural information of the product to facilitate product traceability. It can also be communicatively connected to an external rotating mechanism to enable the operator to grasp information such as the usage times of the probe mechanism 200 and the movement status during use. In this embodiment, the inductor 450 is set as an RFID. The RFID has high sensitivity and can achieve the above functions. At the same time, due to its small volume, when it is disposed on the inner wall of the second rotating bushing 410, the space volume of the storage cavity occupied is small, so that the volume of the interface assembly 100 can be reduced.

[0062] In summary, for the probe device for an endoscope provided in this embodiment, the first rotating bushing 211 is inserted into the first end of the probe barrel 221, and a first sealing member 223 is disposed therebetween. The first end of the sheath tube 222 is hermetically connected to the second end of the probe barrel 221, so as to form a receiving cavity between the imaging mechanism 210, the inner wall of the probe barrel 221, and the inner wall of the sheath tube 222. By loosening the waterproof screw, the ultrasonic medium can be poured into the receiving cavity through the liquid inlet hole 202. By tightening the waterproof screw, the liquid inlet hole 202 is completely blocked to ensure the tightness of the receiving cavity, thereby realizing the recycling of the probe mechanism 200. Then, by providing a transition sleeve 310 outside the probe barrel 221, the sealing member is sleeved on the transition sleeve 310 and abuts against the inner wall of the storage cavity, and the third sealing member 330 is sleeved on the probe barrel 221 and abuts against the inner wall of the storage cavity to achieve secondary sealing of the receiving cavity. With such a setting, even if the waterproof screw becomes loose, the sealing cavity can seal the liquid inlet hole 202, thereby preventing the ultrasonic medium in the receiving cavity from leaking outside the interface assembly 100. During the use of the probe device for an endoscope, by providing the PCB calibration member 430 to enhance the echo signal, the image quality of the image formed on the external receiving mechanism is improved; by providing the PCB protection member 440, the dynamic balance during the rotation of the second rotating bushing 410 is ensured; by providing the RFID, the specific information of the probe mechanism 200 is accurately grasped. In addition, by providing the waterproof cap 500, the whole machine can be disinfected and sterilized without damaging the internal structure, thereby realizing the repeated use of the whole machine.
