Technical Field

[0001] The present application relates to the technical field of medical devices, and further to a medical fixator and an ablation treatment device. Background Art

[0002] Currently, in the field of medical surgery, especially in minimally invasive surgery that requires delicate manipulation, doctors often need to operate multiple medical devices at the same time. For example, in bronchoscopic surgery, doctors need to operate a bronchoscope and its accompanying disposable instruments, such as cryoablation needles. The correct positioning and stable fixation of these instruments are crucial to the success of the operation.

[0003] However, existing methods of fixing medical devices have many inconveniences. During surgery, the optimal operating position is often limited in space, resulting in a crowded surgical area. In addition, assistants are required to manually hold the instruments during surgery to keep them relatively fixed.

[0016] In the length direction of the base portion, the instrument fixing portions are simultaneously located at one end of the base portion or are respectively distributed at both ends of the base portion.

[0017] On the other hand, the present application also provides an ablation treatment device, including: the above-mentioned medical fixator, wherein the number of the instrument fixing portions is three, and a bronchoscope assembly, an endotracheal tube and a flexible cryoprobe are respectively provided at the ends of the three instrument fixing portions;

[0018] The bronchoscope assembly is used for endoscopic examination, the endotracheal tube is used for inserting into the patient's airway to provide respiratory support, and the flexible cryoprobe is used for cryoablation treatment of the lesion site of the patient.

Detailed implementation manners

[0034] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the specific implementation manners of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings in the following description are only some embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other implementation manners can also be obtained.

[0036] It should be further understood that the term "and / or" used in the specification and the appended claims of the present application refers to any combination and all possible combinations of one or more of the related listed items, and includes these combinations.

[0037] In this text, it should be noted that unless otherwise clearly stipulated and defined, the terms "installation", "connection", and "linkage" should be understood in a broad sense.

It is only for the convenience of describing this application and simplifying the description, 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, and therefore cannot be understood as a limitation to this application.

[0039] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0040] In modern medicine, minimally invasive surgery has been widely used due to its advantages such as small trauma and fast recovery. This type of surgery usually requires the use of various precision medical devices, such as the Figure 2 bronchoscope 61, endotracheal intubation 63, and flexible cryoprobe 62 shown in the figure. During the operation, accurately fixing and adjusting the positions of these devices is crucial for the success of the operation.

[0041] However, there are some limitations in the existing medical device fixing methods. For example, during bronchoscopy or pulmonary nodule ablation, doctors need the assistance of assistants to stabilize the devices, but the optimal operating position often has limited space, resulting in a crowded surgical area. In addition, existing fixing methods, such as medical tapes, although they can fix the devices to a certain extent, have problems such as poor stability, inconvenient adjustment, and possible irritation to the patient's skin. Moreover, in ablation surgery, in order to ensure the precise positioning of the ablation needle, it is usually necessary to perform it under the guidance of CBCT. Existing fixing schemes, such as using hemostatic forceps to clamp the delivery tube of the ablation needle and fix it on the patient's body surface, may cause the ablation needle to shake during the CT scan due to lack of sufficient stability, affecting the accuracy of imaging.

[0042] Refer to the appended Figure 1, a medical fixator provided by the present application aims to solve the above problems, and provides an effective, stable and easy-to-operate medical device, which can provide a stable device fixing function, and at the same time allows doctors to quickly and accurately adjust the position of the device according to the surgical needs, so as to improve the success rate and safety of the surgery.

[0043] In one embodiment, a medical fixator provided by the present application includes a base portion 1 and an instrument fixing portion 2. The head end of the instrument fixing portion 2 is movably connected to the base portion 1, and the end of the instrument fixing portion 2 is used to connect the corresponding medical instrument; and the upper area of the base portion 1 is used to support the patient. In the use state, such as preoperative preparation or during the operation, the base portion 1 is fixed at a preset position, such as on the CBCT hospital bed 8 (as shown in the Figure 2 embodiment in the appendix), which can be achieved by the patient's own gravity, or by certain fixing parts or devices. And the corresponding medical instrument can be moved to the lesion position of the patient by medical staff for treatment or pretreatment.

[0044] It can be understood that through the design of the base portion 1 in this embodiment, the direct contact with the patient's body is reduced, the potential irritation to the patient's skin is reduced, and the comfort of the patient is improved.

[0045] And as mentioned above, the base portion 1 can be fixed by an external force, which ensures the stability of the whole device during use and avoids surgical errors caused by instrument displacement. In this embodiment, it is not limited how the external force is realized by what device or equipment. In some implementation cases, magnetic adsorption or vacuum adsorption technology can be used to fix the base portion 1. The magnetic adsorption scheme can be realized by setting magnets between the base portion 1 and the CBCT hospital bed 8, and the vacuum adsorption scheme uses the negative pressure generated by a vacuum pump to fix the base portion 1, and even the base portion 1 can be directly fixed on the CBCT hospital bed 8 to adapt to different surgical environments and requirements.

[0046] In addition, the medical instrument connected to the end of the instrument fixing portion 2 can be moved. In some implementation cases, the main body of this instrument fixing portion 2 is made of flexible materials, such as high-elastic polymers or medical-grade silica gels, which can provide sufficient flexibility without sacrificing stability. This material not only provides good biocompatibility, but also can maintain its shape under different forces, so as to adapt to the dynamic changes during the operation.

[0047] In some other implementation cases, the instrument fixing portion 2 can be designed as a multi-segment structure, and each segment is connected by a hinge mechanism. This multi-segment design allows each segment to move independently, providing flexibility similar to that of a human finger joint. More preferably, the hinge points of each segment can be finely adjusted to achieve precise positioning of the medical instrument.

[0048] Specifically, based on the above, the instrument fixing part 2 includes at least two connecting rods 20. The adjacent two connecting rods 20 are connected by hinges, so that the entire instrument fixing part 2 forms a multi-joint movable structure, which can move flexibly like an arm. This structure can not only adapt to the changes in the positions of different patients, but also achieve precise positioning and adjustment of medical devices during the operation.

[0049] Among them, the head end of the first connecting rod 20 adopts a detachable connection method, so that it can be conveniently connected or separated from the base part 1. The tail end of the last connecting rod 20 also adopts a detachable design, allowing rapid connection with various medical devices. This connection method provides great convenience for the replacement of medical devices, enabling the same instrument fixing part 2 to adapt to a variety of medical devices, and increasing the applicability and flexibility of the fixator.

[0050] It should be noted that Figure 1 in the figure, each instrument fixing part 2 includes two connecting rods 20, but actually one or more intermediate connecting rods can be arranged between the two connecting rods 20, so as to significantly improve the movable range of the instrument fixing part 2.

[0051] It can be understood that in this embodiment, through the detachable connections at both ends, the design of this fixator provides excellent versatility and interchangeability. Medical staff can quickly replace the base part 1 or medical devices according to specific surgical needs, greatly improving the efficiency of surgical preparation and the flexibility of the surgical process. For example, replace the base part 1 as needed to adapt to different support structures or patient body types, or replace the connected medical devices as needed to meet different surgical requirements.

[0052] On the basis of the above embodiment, the hinge form between the connecting rods 20 is further optimized. Specifically, in two connecting rods 20 connected by hinges to each other, a ball joint is provided at the tail end of one connecting rod 20, and a corresponding joint receiving position is provided at the head end of the other connecting rod 20. Of course, vice versa is also possible, that is, a joint receiving position is provided at the tail end of one connecting rod 20, and a ball joint is provided at the head end of the other connecting rod 20. This design not only allows the two connecting rods 20 to rotate freely in multiple directions, but also provides multi-degree-of-freedom movement ability similar to that of human joints. The cooperation between the ball joint and the joint receiving position enables the connecting rod 20 to perform complex multi-plane adjustment in space, greatly improving the manipulation flexibility and positioning accuracy of medical devices during the operation.

[0053] It can be understood that the ball joint adopts a spherical design, with a smooth surface and the ability to rotate freely. The receiving position is designed as a groove that matches the ball joint, which can stably accommodate and allow the ball joint to rotate therein. This structural design not only ensures the stable connection between the two connecting rods 20 but also enables relative rotation at multiple angles between them.

[0054] When constructing a multi-joint movable structure, the present application is not limited to using ball joints for articulated connection. In fact, to meet the requirements of different application scenarios and achieve more diverse movement modes, the articulated connection method of each joint can be flexibly selected according to specific circumstances. Including but not limited to ball joints, various articulated forms such as rotary joints, sliding bearings, and flexible connectors can also be used. For example, a rotary joint can be integrated at the articulated point of the connecting rod 20, allowing the connecting rod 20 to rotate 360 degrees along its entire length. These different articulated methods can be used alone or in combination to achieve diverse movements between the connecting rods 20 and meet the requirements under different working conditions.

[0055] In one embodiment, the instrument fixing part 2 further includes a locking component 21. The locking component 21 is arranged in cooperation with the multi-joint movable structure to lock and unlock one or more joints within the multi-joint movable structure. In this embodiment, the application of the locking component 21 significantly improves the stability between the connecting rods 20, ensures that the medical device can maintain a fixed position during the treatment process, effectively prevents the movement or misalignment of the medical device caused by misoperation or external interference, and reduces the risk of medical accidents.

[0056] It can be understood that the locking component 21 can support controlling all joints at once or independently controlling each joint, depending on the specific requirements and design of the medical fixator. In some cases, the medical fixator may need to lock all joints at once to ensure the stability of the medical device during the treatment process. This design is suitable for situations where overall fixation is required, such as during certain complex surgical operations. The design of independently controlling each joint provides higher flexibility and precision, which means that medical staff can lock or unlock each joint separately according to the treatment needs, thereby precisely adjusting the position and posture of the medical device. This design is more suitable for medical scenarios that require fine operations.

[0057] In this embodiment, the specific form of the locking component 21 is not specifically limited. There are already various implementable locking methods in the current technology. The design of the ball joint in the above embodiment is used as an example for illustration.

[0058] After the ball joint and the joint receiving position are connected and matched, due to the provision of the locking member 21, medical staff can lock the relatively rotatable state between the two connecting rods 20 as needed. Further, the locking member 21 can achieve this function through various mechanisms, such as mechanical locking or hydraulic clamping, etc. Mechanical locking usually involves the cooperation of components such as locking pins and operating elements. The locking pin is inserted between the ball joint and the joint receiving position to prevent relative rotation between the two; hydraulic clamping can apply pressure to the ball joint and the joint receiving position through driving elements such as hydraulic cylinders or air cylinders, making them fit tightly and unable to rotate relative to each other, thereby achieving locking.

[0059] In one embodiment, based on the above embodiment, the above-mentioned locking member 21 includes an operating element and a thimble (not shown in the drawings). The thimble is arranged inside the connecting rod 20. During use, the activation of the operating element will drive the thimble inside the connecting rod 20 to perform corresponding activities. Driven by the operating element, these thimbles will apply pressure to the ball joint, causing the ball joint and the joint receiving position to be pressed against each other, thereby preventing relative rotation between the two connecting rods 20.

[0060] Among them, the operating element (such as a knob) is generally arranged outside the overall structure for the convenience of medical staff to operate. When the operating element is rotated, it will transmit the acting force through the internal mechanical structure, and then drive the thimble inside the connecting rod 20. The thimble is arranged in the channel inside the connecting rod 20, and its two ends are respectively in contact with the operating element and the ball joint. Driven by the operating element, the thimble will move along a predetermined path, and one end of it will press against the surface of the ball joint, making the ball joint firmly locked at a predetermined position of the joint receiving position and unable to rotate freely, so that the instrument fixing part 2 can continuously remain in an immovable state to effectively and safely receive the medical device.

[0061] In one embodiment, a connecting female head 11 is provided on the bottom support part 1, and a connecting male head 22 is provided at the head end of the instrument fixing part 2. The connecting female head 11 and the connecting male head 22 cooperate to achieve the quick and stable connection of the medical device relative to the bottom support part 1.

[0062] In terms of their connection methods, various connection methods such as snap connection, threaded connection, and ball connection can be adopted. These connection methods have their own characteristics and can be selected according to actual needs. The snap connection method is simple and easy to implement, and can achieve quick installation and disassembly; the threaded connection method provides stronger stability to ensure the firmness of the instrument during the operation; while the ball connection method can adapt to complex angular connection requirements and also realizes a large range of rotation of the instrument fixing part 2.

[0063] Furthermore, elastic elements such as buffer pads or springs are added between the female connector head 11 and the male connector head 22. This can play a buffering role when subjected to external force impacts, protecting the connection part from damage.

[0064] In addition, the medical fixator in this application can fix multiple medical devices simultaneously. In one embodiment, there are at least two instrument fixing parts 2, thus forming a multi-channel connection device. The end of each instrument fixing part 2 is detachably connected with a fixing chuck, providing a high degree of flexibility and adaptability.

[0065] Specifically in the application scenario of transbronchial lung nodule ablation, referring to the attached Figure 1 and Figure 2 , the medical fixator can be provided with three instrument fixing parts 2, corresponding to key components such as the tracheal intubation 63, the bronchoscope 61, and the flexible cryoprobe 62 respectively. Each end of the instrument fixing part 2 is equipped with a dedicated fixing chuck: the tracheal plug fixing chuck 5 ensures the stability of the tracheal intubation 63; the bronchoscope fixing chuck 3 provides stable support for the bronchoscope 61; the flexible cryoprobe handle fixing chuck 4 is used to fix the flexible cryoprobe handle for convenient surgical operation. This design not only optimizes the surgical process and improves surgical efficiency, but also ensures the stability and safety of each medical device during the operation. Through this multi-channel connection device, doctors can focus more on the surgery itself without worrying about the fixation problem of medical devices.

[0066] In addition, there are also many connection methods for the fixing chuck relative to the end of the instrument fixing part 2. The connection methods of the female connector head 11 and the male connector head 22 in the above text can be referred to, such as snap, thread, ball head and other connection methods, all of which can be adopted.

[0067] In one embodiment, based on the above embodiment, the base part 1 adopts a long plate-shaped profile, and the surface is smoothed to prevent bumping into the patient's back during the operation. This design not only improves the patient's comfort, but also ensures that the base part 1 can closely fit the patient's body. More importantly, the base part 1 can also achieve natural fixation by means of the patient's gravity. Generally, the base part 1 is made of lightweight and strong materials such as aluminum alloy or carbon fiber composite material to ensure sufficient strength and stiffness while bearing the gravity.

[0068] At the same time, in order to further improve the adaptability and comfort of the base part 1, the surface of the base part 1 can also be designed and adjusted more finely according to the characteristics of the human back contour to better adapt to the patient's body shape.

[0069] In addition, when the number of the instrument fixing parts 2 is two or more, in the length direction of the base part 1, the setting position of the instrument fixing part 2 relative to the base part 1 can be flexibly set according to the surgical requirements. It can be concentrated at one end or distributed at both ends to meet the connection requirements of different medical devices.

[0070] According to another aspect of the present application, the present application further provides an ablation treatment device. In the current medical field, minimally invasive ablation treatment technology has attracted much attention due to its advantages such as small trauma and fast recovery. Especially in the treatment of pulmonary nodules, cryoablation under bronchoscope guidance has become a new and effective method. The ablation treatment device in the present application can effectively fix each medical device required in the ablation treatment and improve the safety of the operation.

[0071] In one embodiment, referring to the appended Figure 2 drawings, the ablation treatment device includes the above-mentioned medical fixator, bronchoscope assembly, tracheal intubation 63 and flexible cryoprobe 62.

[0072] Specifically, there are three instrument fixing parts 2 in the medical fixator, and the ends of the three instrument fixing parts 2 are respectively connected to the above-mentioned bronchoscope assembly, tracheal intubation 63 and flexible cryoprobe 62. Among them, the bronchoscope assembly is used for endoscopic examination, which can observe the pulmonary lesions in real time and provide accurate navigation information for doctors; the tracheal intubation 63 is used to insert into the patient's airway to provide necessary respiratory support. During the ablation treatment, it can ensure the patency of the patient's breathing and reduce the risk of complications; the flexible cryoprobe 62 uses cryogenic freezing technology to ablate pulmonary nodules. Due to its flexible design, it can flexibly reach the lesion site under the guidance of the bronchoscope 61 to achieve precise ablation.

[0073] Appended Figure 2 drawings simulate the use state of the ablation treatment device through a human model 7. Among them, the base part 1 in the medical fixator adopts a long plate-shaped design with a smooth surface, which can fit the contour of the patient's back to ensure stable fixation under the action of the patient's gravity. At the same time, several instrument fixing parts 2 can be flexibly adjusted according to the surgical requirements, which is convenient for doctors to operate. In the drawings, the instrument fixing parts 2 are all located on the right side of the human model 7. In fact, during actual operation, they can also be located on the left side or both sides of the human model 7, and the height of the instruments at their ends can be adjusted in time through the multi-joint movement structure described above, and the use is very flexible and reliable.

[0074] Based on the above embodiment, the bronchoscope assembly includes a bronchoscope 61 and a bronchoscope adjustment knob 613. The bronchoscope 61 has an insertion section 611 and a holding section 612. The holding section 612 is used to provide an operation space, and the bronchoscope adjustment knob 613 is generally arranged on the holding section 612 and is connected to the insertion section 611 in cooperation.

[0075] Specifically, the insertion section 611 can adapt to the complex environment in the airway and accurately reach the lesion site. Under normal circumstances, a high-definition camera and a light source are assembled at its end, which can capture clear images in the airway in real time and provide accurate navigation information for medical staff; the holding section 612 is an important part for medical staff to operate the bronchoscope 61. The bronchoscope adjustment knob 613 at the position of the holding section 612 plays a key role. Through the precise adjustment of the bronchoscope adjustment knob 613, medical staff can easily adjust the bending angle or fixed position of the insertion section 611 of the bronchoscope 61 to ensure the stability and accuracy of the bronchoscope 61 in the airway.

[0076] After the tracheal intubation 63 is successfully inserted into the patient's airway, the insertion section 611 of the bronchoscope 61 can pass through the reserved space of the tracheal intubation 63 and smoothly reach the lesion site along the natural direction of the airway. At this time, medical staff control the direction and angle of the bronchoscope 61 through the bronchoscope adjustment knob 613 on the holding section 612 to ensure that the bronchoscope 61 can accurately aim at the lesion and provide accurate navigation for subsequent ablation treatment.

[0077] In one embodiment, as Figure 3 and Figure 4 shown, the bronchoscope assembly further includes a bronchoscope knob fixator 33 for restricting the movement of the bronchoscope adjustment knob 613.

[0078] Specifically, the bronchoscope knob fixator 33 includes a fixator base 331, a fixator knob 332, a rotary damper 333 and a limit block 334. The fixator base 331 is arranged at the end of the corresponding instrument fixing part 2. The fixator knob 332 is rotatably connected to the fixator base 331. The limit block 334 is elastically connected to the outer periphery of the fixator knob 332, for example, through a return spring 335 for elastic connection.

[0079] It should be noted that the traditional bronchoscope adjustment knob 613 may produce an automatic reset phenomenon without external force, thus affecting the actual position of the bronchoscope 61 and bringing potential risks to the operation. Therefore, through the relevant settings of components such as the limit block 334 in this embodiment, the accidental deflection of the bronchoscope adjustment knob 613 can be effectively restricted.

[0080] Specifically, the rotating holder knob 332 enables the limit block 334 to be in the same position as the bronchoscope adjustment knob 613, and then the limit block 334 is moved to engage with the bronchoscope adjustment knob 613, and the reset spring 335 has a certain elastic force, so that the limit block 334 can press the bronchoscope adjustment knob 613, so that the two cooperate more closely; and the rotating damper 333 limits the deflection of the limit block 334 in the circumferential direction, thereby avoiding the accidental rotation of the bronchoscope adjustment knob 613. At the same time, through the application of the above-mentioned reset spring 335, the limit block 334 can quickly return to the initial position when the bronchoscope adjustment knob 613 is released.

[0081] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application.
