Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to an ultrasonic probe and an ultrasonic testing device. Background Technology

[0002] In thoracoscopic minimally invasive surgery, precise localization of deep, small lesions, such as pulmonary nodules or lesions in the mediastinum, is required. Ultrasound, with its advantages of no radiation, easy repeatability, and real-time guidance, can accurately locate deep lesions and is therefore increasingly widely used in thoracoscopic minimally invasive surgery.

[0003] Currently, there are no intraoperative ultrasound probes specifically designed for thoracoscopic surgery on the market. Clinically, laparoscopic ultrasound probes are usually used in thoracoscopic surgery. However, unlike laparoscopic surgery, which can utilize an insufflator to inject gas and obtain sufficient surgical space, the thoracic cavity is limited by anatomical structures such as the ribs and cannot be inflated like the abdominal cavity. This makes the surgical space in thoracoscopic surgery smaller than in laparoscopic surgery. Existing laparoscopic ultrasound probes suffer from problems such as poor fit with lung tissue, long overall probe length making them difficult to control, and inability to meet the needs of clinical puncture biopsy. Therefore, there is a need for an ultrasound probe that can flexibly adjust the scanning position according to the needs of the surgery, closely fit the tissue, and provide continuous guidance. Utility Model Content

[0004] To at least partially address the problems existing in the prior art, some embodiments of this application provide an ultrasound probe for thoracoscopic surgery, including an insertion part comprising a flexible insertion tube and an acoustic head disposed at the distal end of the flexible insertion tube. The flexible insertion tube includes a universal bending shaping tube, any segment of which is constructed to be isotropically bendable at a certain angle to its axis and has the ability to remember its bent shape. The distal end of the acoustic head is provided with a spaced-apart adjustment part and an ultrasound window, wherein: the adjustment part is used to receive the traction of surgical instruments, causing the flexible insertion tube to bend toward a target direction; the ultrasound window is used to transmit ultrasound.

[0005] For example, the insertion part is further provided with an instrument channel, wherein: the acoustic head is provided with an instrument opening, and the instrument channel extends from the proximal end of the insertion part to the instrument opening of the acoustic head.

[0006] For example, there are two instrument openings, and the two instrument openings are respectively located on opposite sides of the ultrasonic window along the width direction.

[0007] For example, at least a portion of the ultrasonic window has an angle with the axis of the flexible insertion tube, such that the ultrasonic window faces the front or side of the ultrasonic probe.

[0008] For example, the ultrasonic window has a first end and a second end opposite each other along its length, the first end being at a greater distance from the flexible insertion tube than the second end is at the same distance from the flexible insertion tube, such that the ultrasonic window faces the distal end and side of the ultrasonic probe.

[0009] For example, the adjustment section is adjacent to the distal end of the ultrasonic window.

[0010] For example, the adjustment section is located outside the scanning angle of the ultrasound window.

[0011] For example, the adjustment part includes: a neck extending distally from the head of the sound; and an end cap connected to the distal end of the neck, the neck being narrower than the end cap.

[0012] For example, the flexible insertion tube also includes a flexible layer covering the outside of the universal bending shaping tube.

[0013] For example, the universal bending shaping tube is a gooseneck tube.

[0014] For example, the insertion portion also includes a rigid insertion tube connected to the proximal end of the flexible insertion tube.

[0015] For example, the ultrasound probe also includes an operating portion connected to the proximal end of the insertion portion.

[0016] For example, the operation unit is provided with operation buttons.

[0017] For example, the surface of the operating part is provided with an instrument channel inlet, and the insertion part is also provided with an instrument channel, the instrument channel inlet being connected to the proximal end of the instrument channel.

[0018] This application also provides an ultrasound detection device for thoracoscopic surgery, including the aforementioned ultrasound probe; and an ultrasound connector connected to the ultrasound probe via a cable.

[0019] This application also provides a thoracoscopic surgical device, including the aforementioned ultrasound detection device; and a thoracoscope having an instrument channel for surgical instruments that pull the adjustment section of the ultrasound detection device to pass through.

[0020] In the above technical solution, a flexible insertion part capable of omnidirectional bending is employed. During the operation, the operator can manually adjust its shape to allow it to enter the patient's body through the trocar (surgical instrument insertion channel) in the chest cavity. Inside the patient's body, the adjustment part can be clamped by surgical instruments, thereby bending the flexible insertion tube so that the ultrasound window of the ultrasound probe faces and closely adheres to the target location to be detected. Thus, the ultrasound probe has sufficient degrees of freedom to reach almost any location within the chest cavity through the existing trocar opening, and the ultrasound window can be directly aligned with and closely fitted to the location to be detected. This avoids situations where the current position of the trocar opening restricts the ultrasound probe, preventing it from reaching the target location or the ultrasound window from facing the target area, thus necessitating the creation of an additional trocar opening in the chest cavity. The spacing between the adjustment part and the ultrasound window prevents damage to the ultrasound window by the surgical instruments when adjusting the ultrasound probe position. When the operator places the ultrasound window in the target position, the memory capability of the flexible insertion tube allows the operator to focus on the surgical procedure without having to adjust the position of the ultrasound probe afterward.

This utility model description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0033] In the following description, numerous details are provided to enable a thorough understanding of this application. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the application by way of example only. Furthermore, to avoid confusion with this application, some technical features well-known in the art have not been described in detail.

[0034] This application provides an ultrasound probe for thoracoscopic surgery. For example... Figure 1As shown, the ultrasound probe includes an insertion portion 100, which includes a flexible insertion tube 110 and an acoustic head 120 disposed at the distal end of the flexible insertion tube 110. It should be understood that the proximal end refers to the end of the ultrasound probe closest to the operator during use, and the distal end refers to the end of the ultrasound probe furthest from the operator, or closer to the patient. The acoustic head 120 may include an ultrasound transducer disposed within its housing, and an ultrasound window 122 disposed on the surface of the housing and matched to the ultrasound transducer for transmitting ultrasound. For ease of understanding, the ultrasound transducer and the ultrasound window can be collectively referred to as an ultrasound assembly. By placing the ultrasound assembly at the distal end of the ultrasound probe, the ultrasound probe is configured as an end-scan type. This allows for image scanning simply by placing the probe tip at the target location, meeting the clinical requirement of "point-and-shoot" in thoracoscopic surgery. Optionally, the ultrasound assembly can be a convex array structure or a linear array structure. Figure 3 As shown, the opening area corresponding to the straight lines on both sides of the ultrasound window 122 (which represents the maximum scanning angle) has a large scanning angle, allowing for scanning of a larger area and thus facilitating the location of lesions; while linear array structures (such as...) Figure 4 As shown, the ultrasound module with a smaller scanning angle (the opening area corresponding to the straight lines on both sides of the ultrasound window 122 is the maximum scanning angle) has a smaller scanning angle, allowing for precise scanning of the target area. The scanning angle is shown by the thick solid line in the figure. During the operation, the operator can first use an ultrasound probe with a convex array structure to scan. After determining the location of the lesion, the operator switches to an ultrasound probe with a linear array structure to carefully locate the lesion, and then performs the operation in conjunction with a thoracoscope and surgical instruments. Optionally, the operator can also use only one type of ultrasound probe during the operation. For the linear array structure ultrasound module, some embodiments of the ultrasound probe have extended imaging capabilities. Specifically, for example, the linear array ultrasound module can use phased array and other technologies to make the emitted ultrasound waves appear as... Figure 3 The convex array ultrasound assembly shown also has a large divergence scanning angle. In summary, the ultrasound probe of this application can use any ultrasound assembly that is currently available on the market or that may appear in the future. The flexible insertion tube 110 can have a lumen space, and the connecting wire of the ultrasound assembly can extend within the lumen space to the proximal end of the ultrasound probe. The entire insertion portion 100 of the ultrasound probe can be inserted into the patient's body through a trocar port (a puncture hole left on the body surface) provided in the chest cavity, so as to conform to the tissue to be scanned by ultrasound and perform an internal ultrasound scan of the tissue.

[0035] It should be noted that ultrasound waves require a medium of suitable density for transmission. In laparoscopic surgery, the ultrasound probe used in the laparoscope can be immersed in saline solution injected into the abdominal cavity to scan the surrounding tissue. However, the ultrasound probe used in thoracoscopy may not be immersed in saline solution, potentially creating air gaps between the ultrasound window 122 and the tissue, affecting the scanning effect. During scanning, the ultrasound window 122 adheres closely to the tissue surface to scan the internal tissue.

[0036] The flexible insertion tube 110 may include a universal bending shaping tube, any segment of which is constructed to be isotropically bend at a certain angle to its axis and possesses the ability to retain its bent shape. The axis direction can be considered as the centerline of the universal bending shaping tube in its straightened state. The universal bending shaping tube can be made of any suitable material such as stainless steel, nickel-titanium alloy, or organic composite material; it can be a biocompatible material itself or have a biocompatible material coating on its surface. Before inserting the insertion portion 100 of the ultrasound probe into the patient's body, the operator can manually bend the flexible insertion tube 110 to form the desired shape. The "memory" capability refers to the ability of the flexible insertion tube 110 to maintain its shape after being bent to a certain shape under external force and when the external force is removed. Preferably, after the flexible insertion tube 110 is bent, it will not bend under gravity or spring back under its own elasticity, thereby preventing the ultrasound probe from deviating from the scanning position during surgery.

[0037] An adjustment part 121 may also be provided at the distal end of the sound head 120 (see reference). Figures 2-5 The adjustment section 121 may be spaced apart from the ultrasound window 122. The adjustment section 121 is used to receive the surgical instrument 40 (see reference). Figure 5 The traction of the flexible insertion tube 110 causes it to bend towards the target direction. The surgical instrument 40 can be any instrument used in thoracoscopic surgery capable of clamping objects, such as hemostats or thoracoscopic clamps. The surgical instrument 40 is typically made of metal, which may result in low friction with metal objects. Furthermore, the size that the surgical instrument 40 can clamp is limited; the larger the object being clamped, the less secure the clamping force. Therefore, compared to clamping a large-diameter, smooth-surfaced head 120 or the flexible insertion tube 110, providing an adjustment part 121 of suitable shape and size facilitates clamping of the surgical instrument and provides a force point to bend the flexible insertion tube 110 in the direction desired by the operator. Optionally, the adjustment part 121 can be constructed to be flat, thereby facilitating clamping by the surgical instrument 40.

[0038] In the above technical solution, a flexible insertion tube 110 capable of omnidirectional bending is used. During the operation, the operator can manually adjust its shape to allow it to enter the patient's body through the trocar opening in the chest cavity in a suitable shape. Inside the patient's body, the adjustment part 121 can be clamped by the surgical instrument 40, thereby bending the flexible insertion tube 110 inside the patient's body so that the ultrasound window 122 of the ultrasound probe faces and fits tightly against the target location to be detected. Thus, the ultrasound probe has sufficient degrees of freedom to reach almost any location within the chest cavity through the existing trocar opening, and the ultrasound window 122 can be directly facing and tightly fitted against the location to be detected. This avoids situations where the current position of the trocar opening restricts the ultrasound probe, preventing it from reaching the target location or the ultrasound window 122 from facing the target area, thus necessitating the creation of an additional trocar opening in the chest cavity. The spaced arrangement of the adjustment part 121 and the ultrasound window 122 prevents damage to the ultrasound window 122 by the surgical instrument when adjusting the position of the ultrasound probe. When the operator places the ultrasound window 122 into the target position, the memory capability of the flexible insertion tube 110 allows the operator to focus on the surgical procedure without having to adjust the position of the ultrasound probe afterward.

[0039] For example, an instrument channel is also provided within the insertion section 100. (See reference) Figure 2The ultrasound head 120 may have an instrument opening 123, and the instrument channel extends from the proximal end of the insertion part 100 and connects to the instrument opening 123 of the ultrasound head 120. As described above, the flexible insertion tube 110 can be reshaped manually or under the operation of the surgical instrument 40. In other words, the bending of the flexible insertion tube 110 does not require a built-in traction cord as is the case with some endoscopes in the prior art. Thus, while keeping the lumen space of the flexible insertion tube 110 approximately constant, an instrument channel can be provided in addition to the cable for the ultrasound probe. When the ultrasound probe is in position, the operator can insert a treatment instrument from the distal end of the ultrasound probe. The inner diameter of the instrument channel is typically not less than 2.8 mm to allow treatment instruments such as puncture needles, biopsy forceps, suction needles, and cell brushes to pass through. This meets the clinical application needs of intraoperative puncture, grasping, radiofrequency ablation, and ablation. Taking a puncture needle as an example, when the scanning direction of the ultrasound component is roughly consistent with the extension direction of the instrument channel, the puncture needle can be directly inserted into the ultrasound scanning area through the instrument opening 123 of the ultrasound head, thus performing puncture under ultrasound guidance. Therefore, the puncture needle can directly reach the optimal puncture angle and position under the guidance of the instrument channel and instrument opening 123, without the need for an additional opening in the thoracic cavity or additional adjustments to the angle and position of the puncture needle. In the embodiment where the ultrasound component can extend imaging, the extended imaging function can expand the ultrasound scanning angle to be consistent with the direction of the instrument channel, ensuring that the ultrasound image scanning and instrument operation are in the same direction, guaranteeing that the treatment is performed on the same operating plane under ultrasound guidance.

[0040] Exemplarily, the adjustment portion 121 may include a neck 1211 and an end cap 1212, the neck 1211 extending distally from the head of the surgical instrument, and the end cap 1212 connected to the distal end of the neck 1211, the neck 1211 being narrower than the end cap 1212. Optionally, the adjustment portion 121 may be formed by a screw, the thinner portion of the screw serving as the neck 1211 of the adjustment portion 121, and the head of the screw forming the end cap 1212 of the adjustment portion 121. When the surgical instrument 40 clamps the neck 1211, the end cap 1212 can prevent the surgical instrument 40 from accidentally slipping off the neck 1211. When the flexible insertion tube 110 is bent, the proximal face of the end cap 1212 can abut against the surgical instrument 40, such as... Figure 5 As shown. This allows the operator to effectively transfer force to the flexible insertion tube 110, thereby moving the ultrasound probe to the appropriate position with a limited range of motion.

[0041] For example, there are two instrument openings 123, which are respectively located on opposite sides of the ultrasound window 122 along its width direction. The ultrasound window 122 is located at the center of the ultrasound head 120, which is more in line with the usage habits of ordinary people. Each instrument opening 123 corresponds to an instrument channel, which can be formed by a tube. The outer diameter of the tube can be determined by the material of the tube; for example, the lower the strength of the tube material, the thicker the tube wall needs to be to prevent the treatment instrument from puncturing the tube. The tube usually has a circular cross-section, and the lumen space inside the flexible insertion tube 110 is also usually constructed with a circular cross-section. By placing the two tubes on both sides of the lumen space, the space formed between the two tubes can accommodate the cable, thereby making good use of the lumen space of the flexible insertion tube 110. The two instrument openings 123 allow the operator to use more treatment instruments to perform more complex actions without the need for an additional trocar in the patient's chest cavity. In one application scenario, two instrument openings 123 can each extend different treatment instruments. The two treatment instruments can cooperate with each other, and the two treatment instruments extending from both sides will not interfere with each other, and both are within the scanning range of the ultrasonic window 122.

[0042] In some embodiments, the ultrasonic window can be disposed on the distal end face of the ultrasonic head, such that the ultrasonic window faces forward of the ultrasonic probe along the axial direction. Here, "forward" can refer to the distal end of the ultrasonic probe along the axial direction.

[0043] For example, at least a portion of the ultrasound window may form an angle with the axis of the flexible insertion tube, such that the ultrasound window faces the anterior or lateral side of the ultrasound probe. When exploring intrathoracic tissues, the ultrasound window 122 is typically oriented vertically when the patient is lying supine, and laterally. Figure 5 As shown, the ultrasound window 122 faces the side-front of the ultrasound probe, allowing the probe to be bent at a small angle after entering the body to align the ultrasound window 122 with the organ to be scanned. Specifically, for example, the operator can slightly bend the flexible insertion tube 110 and insert it into the thoracic cavity 30 through a trocar opening on the front of the cavity. Then, through the trocar opening on the front of the thoracic cavity 30, the surgical instrument 40 clamps the adjustment part 121, aligning the ultrasound window 122 with the area to be scanned. During this process, the surgical instrument 40 holding the adjustment part 121 can remain vertical with a small range of motion. The operation is similar for embodiments where the ultrasound window 122 faces the side of the ultrasound probe. As shown, exemplarily, the ultrasound window 122 has a first end 10 and a second end 20 opposite each other along its length, with the distance from the first end 10 to the flexible insertion tube 110 being greater than the distance from the second end 20 to the flexible insertion tube 110.

[0044] For embodiments where the ultrasonic window faces the side-front of the ultrasonic probe, such as Figure 6 As shown, the ultrasound head 120 can also enter the gaps between organs within the thoracic cavity 30 to a certain extent, allowing the scanning direction to be tilted horizontally. Compared to ultrasound probes where the centerline of the scanning direction is roughly aligned with the axis, ultrasound probes with at least part of the scanning range facing to the side require a smaller bending angle, making them more suitable for thoracoscopic surgical scenarios. It should be noted that... Figure 5 and Figure 6 To clearly show the position of the ultrasound probe, the ratio of the ultrasound probe to the thoracic cavity 30 has been adjusted, and does not represent the actual proportional relationship between the ultrasound probe and the human thoracic cavity 30 in this application.

[0045] For example, the adjustment section is adjacent to the distal end of the ultrasonic window. (Continue to refer to...) Figure 5 When the adjustment unit 121 is held by the surgical instrument 40, the ultrasound scanning area is generally oriented in the opposite direction to the handle of the surgical instrument 40. This makes it easier for the operator to hold the adjustment unit 121 and align the ultrasound window 122 with the target area. Furthermore, when operating the adjustment unit 121 with the surgical instrument 40, the surgical instrument 40 will not obstruct the field of view of the ultrasound component. In addition, the adjustment unit 121 is located at the tip, which does not increase the outer diameter of the ultrasound probe, thus eliminating the need for a large trocar opening and reducing potential harm to the patient.

[0046] The process of adjusting the ultrasound probe can be performed under the thoracoscopy view without relying on the ultrasound assembly for scanning. For example, the adjustment unit 121 can be located outside the scanning angle of the ultrasound window 122. During the process of adjusting the ultrasound probe to the appropriate position, neither the adjustment unit 121 nor the surgical instruments 40 clamped on the adjustment unit 121 will appear in the ultrasound field of view, thus avoiding interference with the operator's process of aiming the ultrasound probe at the target area.

[0047] For example, the flexible insertion tube 110 also includes a flexible layer covering the outside of the universal bending tube. Universal bending tubes typically include an inner spring and an outer spirally coiled metal strip, giving them isotropic bending properties and shape memory. This results in gaps on the surface of the universal bending tube, allowing liquids, gases, etc., to enter the gaps and lumen space during surgery or storage. Unlike disposable instruments such as intravascular guidewires, ultrasound probes need to be reused. This can lead to blind spots in the gaps and lumen space that cannot be disinfected, increasing the patient's risk of infection. The flexible layer can completely seal the gaps on the surface of the flexible insertion tube without affecting its mechanical properties. Therefore, during disinfection, there are no blind spots that are difficult to disinfect the ultrasound probe, and gases and liquids will not corrode the universal bending tube or the cables and conduits forming the instrument channel within the lumen space. The flexible layer can be made of biocompatible materials, thus eliminating the need for biocompatible materials in the universal bending tube encased within it. Biocompatible materials are often expensive and have slightly poor mechanical properties. Adding a flexible outer layer can achieve better mechanical properties and reduce costs.

[0048] For example, the universal bending shaping tube can be a gooseneck tube. The reliability of the gooseneck tube structure has been proven over a long period of time, and the manufacturing process is simple and inexpensive. By selecting appropriate materials to process the gooseneck tube, its performance can meet the requirements of ultrasonic probes.

[0049] Return to reference Figure 1 Exemplarily, the ultrasound probe may also include an operating part 200 connected to the proximal end of the insertion portion 100. The surface of the operating part 200 may be provided with an instrument channel inlet 210, and the insertion portion 100 also has an instrument channel, the instrument channel inlet 210 being connected to the proximal end of the instrument channel. Thus, the operator can insert a treatment instrument outside the patient's body into the instrument channel inlet 210, the treatment instrument being guided along the instrument channel and extending from the instrument opening 123. The operating part 200 may be configured to be easy for the operator to hold, and in some embodiments, the operating part 200 may also be configured for connection to a device such as a surgical robotic arm. It should be noted that... Figure 1 The red circle pointing to number 210 is an indicator circle used to delineate the instrument channel entrance 210, and is not an actual structure on the operating unit 200.

[0050] like Figure 8 As shown, the operation unit 200 may be equipped with operation buttons 220. The operation buttons 220 can control the ultrasound host connected to the ultrasound probe. The operator can adjust the ultrasound image or control ultrasound imaging through the operation buttons 220, such as freezing / thawing the image or adjusting imaging parameters. There can be multiple operation buttons 220, each of which performs different operation controls.

[0051] For example, the insertion section 100 may also include a rigid insertion tube connected to the proximal end of the flexible insertion tube 110. The rigid insertion tube near the operating section 200 has a certain rigidity, which allows the probe to move a wider range within the thoracic cavity during thoracoscopic minimally invasive surgery. This avoids the situation where the actual location of the lesion does not match the expected location, resulting in poor scanning vision or even inability to locate the lesion after the thoracoscope is inserted into the thoracic cavity through the expected trocar opening. This would increase the number of trocar openings required or the risk of converting the minimally invasive surgery to open thoracotomy.

[0052] This application also provides an ultrasound detection device for thoracoscopic surgery, the ultrasound detection device including the aforementioned ultrasound probe and an ultrasound connector 400, the ultrasound connector being connected to the ultrasound probe via a cable 300. (Refer to the reference...) Figure 1 and Figure 7 The ultrasonic connector 400 may be equipped with a waterproof cover 410 and a locking pin 420 so that the entire ultrasonic testing device can be immersed in liquid for sterilization.

[0053] This application also provides a thoracoscopic surgical device, including the aforementioned ultrasound detection device and a thoracoscope. The thoracoscope has an instrument channel for surgical instruments that allow the adjustment section of the ultrasound detection device to pass through. This can significantly reduce the number of trocar openings required for thoracoscopic surgery.
