[0002] Puncture surgery is a minimally invasive interventional medical method that is widely used, especially in the treatment of tumors. During minimally invasive interventional treatment, the puncture needle is inserted into the tumor site in the patient's body (the tumor site is called the target site), and then a puncture biopsy, microwave, radiofrequency or cryoablation is performed.

[0003] Ultrasonic images are often used to guide puncture of targets in the patient's body due to their convenience in acquisition and real-time nature. During the operation, the magnetic field generator is turned on so that the spatial area where the lesion is located is covered by the magnetic field. When the ultrasound probe scans the tumor site, the location information of the probe can be obtained through the positioning sensor in the ultrasound probe, and then the location information of the tissue scanned by the probe can be obtained, so that the location information of the tumor, blood vessels, etc. can be used to guide the physician to use the puncture needle for puncture surgery.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] It should also be understood that the terms used in this utility model specification are only for describing specific realities. In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0041] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0042] like Figures 1 to 10 As shown, the present application provides a bracket 100 for installing a magnetic field generator 200; the bracket 100 includes a support assembly 20 and a joint assembly 10, the joint assembly 10 includes a pitch joint 12, the pitch joint 12 is connected to the support assembly 20 and can move along the height direction of the support assembly 20, so that the magnetic field generator 200 installed on the pitch joint 12 can be suspended on the support assembly 20, wherein the pitch joint 12 is used to realize the pitch rotation of the magnetic field generator 200, so that the magnetic field generator 200 can have a relatively flexible position change in the pitch direction, so that the position of the magnetic field generator 200 can be adjusted as needed, so that the spatial position relationship of the ultrasonic probe with a magnetic sensor can be obtained within the magnetic field range of the magnetic field generator 200, which is beneficial for medical staff to grasp the spatial position relationship of the tissue near the patient's lesion and perform puncture.

[0043] It should be noted that the “connection” between the pitch joint 12 and the support assembly 20 includes “direct connection” and “indirect connection”; for example, the pitch joint 12 is directly connected to the support assembly 20 without the aid of other rotational joints; or, the pitch joint 12 is connected to the support assembly 20 through other rotational joints, and the other rotational joints include but are not limited to the horizontal joint 11 whose rotation axis is perpendicular to the rotation axis of the pitch joint 12. At the same time, the present application does not limit the number of horizontal joints 11.

[0044] In an optional embodiment, the joint assembly 10 includes at least one horizontal joint 11, and the pitch joint 12 is rotatably mounted on the support assembly 20 through at least one horizontal joint 11, so that the magnetic field generator 200 mounted on the pitch joint 12 can be suspended on the support assembly 20. Among them, the pitch joint 12 is used to realize the pitch rotation of the magnetic field generator 200, and the horizontal joint 11 is used to realize the horizontal rotation of the magnetic field generator 200, so that the magnetic field generator 200 can have a relatively flexible position change in the pitch direction and the horizontal direction, so that the position of the magnetic field generator 200 can be adjusted as needed, so that the spatial position relationship of the ultrasound probe with a magnetic sensor can be obtained within the magnetic field range of the magnetic field generator 200, which is beneficial for medical staff to grasp the spatial position relationship of the tissue near the patient's lesion and perform puncture.

[0045] For example, when the medical staff turns on the magnetic field generator 200 during the operation, the surgical environment is covered by the magnetic field. When the ultrasound probe scans the tumor site, the sensor in the ultrasound probe can sense the spatial position information of the probe in the magnetic field, and cooperate with the navigation sensor to obtain the spatial position information of the tumor, so as to guide the puncture needle to puncture. In order to make the magnetic field cover all lesions, it is necessary to adjust the magnetic field generator 200 to a suitable placement position and posture. Therefore, in order to make the magnetic field generator 200 have flexible position changes, the magnetic field generator 200 can be suspended on the support assembly 20 through the pitch joint 12 and the horizontal joint 11, and can be adjusted in the pitch and horizontal directions as needed. It is very convenient to operate, and the magnetic field generator 200 can be operated with one hand, avoiding inconvenience to medical staff during the operation.

[0046] In an optional embodiment, the joint assembly 10 can move along the height direction of the support assembly 20 to achieve position adjustment of the magnetic field generator 200 in the height direction.

[0047] In an optional embodiment, if Figures 2 to 4 As shown, the pitch joint 12 includes a first connecting seat 122, a second connecting seat 123 and a connecting member 121 connected to the horizontal joint 11. The first connecting seat 122 and the second connecting seat 123 are arranged at both ends of the connecting member 121, and are used to connect with both sides of the magnetic field generator 200, so that the magnetic field generator can be pitched and rotated relative to the connecting member; at the same time, it is also convenient to distribute the weight of the magnetic field generator 200 to the first connecting seat 122 and the second connecting seat 123, so that the magnetic field generator 200 can be firmly fixed on the first connecting seat 122 and the second connecting seat 123; at the same time, the two sides of the magnetic field generator 200 are connected to the first connecting seat 122 and the second connecting seat 123, so that medical personnel can stably operate it with one hand, without having to adjust the pitch angle of the magnetic field generator 200 with both hands.

[0048] It should be noted that the number of horizontal joints 11 can be one or more; at the same time, multiple horizontal joints 11 can be used one by one, and multiple horizontal joints 11 can also be used in combination. When used in combination, the magnetic field generator 200 will have more position changes and is more flexible and convenient to use, and this application does not limit it.

[0049] In an optional embodiment, if Figures 2 to 6 As shown, the first connecting seat 122 and the second connecting seat 123 both include a connecting shaft 1222 and a connecting seat 1221 for connecting to the magnetic field generator 200, one end of the connecting shaft 1222 is connected to the connecting member 121, and the other end of the connecting shaft 1222 passes through the connecting seat 1221 and is rotatably connected to the connecting seat 1221, so that the magnetic field generator 200 can be rotatably installed on the horizontal joint 11 through the cooperation between the connecting shaft 1222 and the connecting seat 1221.

[0050] It should be noted that the connecting shaft 1222 on the first connecting seat 122 and the second connecting seat 123 can be a rotating shaft 121a that is an integral structure with the connecting member 121; the connecting shaft 1222 on the first connecting seat 122 and the second connecting seat 123 can also be separately provided from the connecting member 121 and then connected together by assembly, which is not limited in the present application.

[0051] In an optional embodiment, the first connecting seat 122 and the second connecting seat 123 also include a damping member 1223, and the two ends of the damping member 1223 are respectively connected to the connecting seat 1221 and the connecting shaft 1222, for generating corresponding damping force to realize the damping and positioning functions of the first connecting seat 122 and the second connecting seat 123, so that the magnetic field generator 200 tends to be stable during the rotation through the pitch joint 12 and is maintained during the pitch rotation, thereby avoiding the magnetic field generator 200 from rotating relative to the first connecting seat 122 and the second connecting seat 123 without external force, thereby reducing the problem of the magnetic field generator 200 automatically rotating downward due to gravity during surgery.

[0052] After adopting the above technical solution, when the operator rotates the magnetic field generator 200, the damping member 1223 generates resistance in the opposite direction of rotation of the magnetic field generator 200. This not only effectively limits the pitch rotation of the magnetic field generator 200 and avoids the randomness of the pitch rotation of the magnetic field generator 200, but also can obtain the best user experience effect during the pitch rotation.

[0053] In an optional embodiment, the damping member 1223 includes a first elastic member 12231, one end of the first elastic member 12231 abuts against the connecting seat 1221, and the other end of the first elastic member 12231 abuts against the connecting shaft 1222, and is used to generate a damping force to maintain the relative position between the connecting seat 1221 and the connecting shaft 1222, so that the magnetic field generator 200 generates resistance during the rotation process, and the magnetic field generator 200 can be stationary at any angle. When it is necessary to adjust the pitch angle of the magnetic field generator 200, the medical staff can apply an external force to the magnetic field generator 200, so that the magnetic field generator 200 can rotate upward or downward relative to the horizontal joint 11 or the support assembly 20 under the action of the external force.

[0054] Exemplarily, the magnetic field generator 200 can rotate to the first state and the second state relative to the horizontal joint 11 or the support assembly 20, and can be maintained at any angle between the first state and the second state. The first state can be the highest position of the magnetic field generator 200 relative to the horizontal joint 11 or the support assembly 20 during the pitch rotation process, and the second state can be the lowest position of the magnetic field generator 200 relative to the horizontal joint 11 or the support assembly 20 during the pitch rotation process. The damping force generated by the first elastic member 12231 can keep the magnetic field generator 200 at any angle between the first state and the second state. When an external force is applied, the magnetic field generator 200 overcomes the damping force of the first elastic member 12231, so that the magnetic field generator 200 can rotate between the first state and the second state, or change from the first state to the second state, or change from the second state to the first state, and the present application is not limited thereto.

[0055] In an optional embodiment, the damping member 1223 includes a second elastic member 12232, one end of the second elastic member 12232 is connected to the connecting seat 1221, and the other end of the second elastic member 12232 is connected to the connecting shaft 1222, and is used to generate a supporting torque that can be balanced with the magnetic field generator 200, so that when the magnetic field generator 200 is within the working angle range, the operating force values ​​of the medical staff when controlling the pitch rotation of the magnetic field generator 200 are close, thereby improving the user's operation smoothness.

[0056] After adopting the above technical solution, since the magnetic field generator 200 is connected to the connecting member 121 through the first connecting seat 122 and the second connecting seat 123, and the connecting member 121 is connected to the supporting assembly 20 through the horizontal joint 11, it is convenient to adjust the pitch angle of the magnetic field generator 200; at the same time, the first connecting seat 122 and the second connecting seat 123 are provided with a first elastic member 12231 and a second elastic member 12232, and the first elastic member 12231 can generate a damping force, so that the magnetic field generator 200 generates resistance during the rotation process, and the magnetic field generator 200 can be stationary at any angle; the second elastic member 12232 can generate a supporting torque for balancing the gravity torque of the magnetic field generator 200, so that the pitch rotation operating force value of the magnetic field generator 200 is close within the working angle range, thereby improving the user's operation smoothness.

[0057] In an optional embodiment, the first elastic member 12231 includes a plurality of disc springs, and the second elastic member 12232 includes a torsion spring. The plurality of disc springs are superimposed on each other and movably sleeved on the outside of the connecting shaft 1222. The torsion spring is sleeved on the outside of the plurality of disc springs, so that the magnetic field generator 200 can obtain the damping force through the plurality of disc springs, and can obtain the support torque for balancing the gravity through the torsion spring. Compared with ordinary springs, the disc spring not only has high rigidity and less wear on the installed parts, but also can be sleeved on the outside of the connecting shaft 1222, without changing the structure of the first connecting seat 122 and the second connecting seat 123, but also conveniently installs the torsion spring on the outside of the disc spring group formed by the plurality of disc springs, and has a simple structure and is easy to set up.

[0058] In an optional embodiment, the first connecting seat 122 and the second connecting seat 123 also include a limiting member 1224 connected to the connecting shaft 1222, and the limiting member 1224 is provided with a first limiting portion 12241, and the connecting seat 1221 is provided with a second limiting portion 12211. The first limiting portion 12241 cooperates with the second limiting portion 12211 to limit the rotation range of the connecting shaft 1222 relative to the connecting seat 1221, thereby effectively preventing the direction of the magnetic field generator 200 from deviating from the patient's position during the rotation process, which is more conducive to the operation and use of medical staff.

[0059] Exemplarily, the first limiting portion 12241 is a limiting groove provided on the limiting member 1224, and the second limiting portion 12211 is a limiting platform provided on the connecting seat 1221, and the limiting platform cooperates with the limiting groove to limit the rotation range of the connecting shaft 1222 relative to the connecting seat 1221. The limiting groove has two extreme positions, that is, the limiting platform can only move between the two extreme positions of the limiting groove.

[0060] In an optional embodiment, the working angle range of the magnetic field generator 200 after the limiting platform and the limiting groove cooperate is between 0° and 45°.

[0061] In an optional embodiment, the connecting seat 1221 is an L-shaped structure, the horizontal end of which is connected to the magnetic field generator 200, the vertical end of the connecting seat 1221 is provided with a connecting seat 1221 rotating hole, and the connecting shaft 1222 is inserted into the connecting seat 1221 rotating hole. The connecting shaft 1222 includes a core shaft 12221 and a fastener 12222, one end of the core shaft 12221 is provided with a connecting shaft mounting portion 1222b, the other end of the core shaft 12221 is provided with a connecting shaft stud 1222a, the connecting shaft mounting portion 1222b is connected to the connecting member 121, the fastener 12222 is fixed on the connecting shaft stud 1222a of the core shaft 12221 passing through the connecting seat 1221 rotating hole, and the damping member 1223 is arranged between the vertical end of the connecting seat 1221 and the fastener 12222. After adopting the above technical solution, not only can the damping force of the damping member 1223 be adjusted by the fastener 12222, but the structure is also relatively simple, which is convenient for installation and manufacturing.

[0062] In an optional embodiment, the connecting shaft 1222 includes a damping washer 12223, and the fastener 12222 is a fastening nut. The damping washer 12223 is arranged on the side of the fastening nut facing the damping member 1223, and is connected to the core shaft 12221 or the fastener 12222 and can rotate with the core shaft 12221, and is used to connect with the damping member 1223. The damping washer 12223 is provided with a connecting hole, one end of the torsion spring is fixed in the connecting hole, and the other end of the torsion spring is connected to the connecting seat 1221, so that when the magnetic field generator 200 rotates downward, the torsion spring is torsionally deformed to generate a supporting force and store energy, and the magnitude of the supporting force matches the gravity of the magnetic field generator 200, so that the magnetic field generator 200 can be stabilized during the pitch rotation process. When the magnetic field generator 200 rotates upward, the torsion spring can release the stored energy to balance the gravity of the magnetic field generator 200, that is, the rotation direction of the magnetic field generator 200 after the torsion spring releases the stored energy is opposite to the rotation direction under its own gravity, so that the magnetic field generator 200 can achieve balance whether it rotates upward or downward. Among them, one end of the disc spring group formed by multiple disc springs is in contact with the damping washer 12223, and the other end of the disc spring group is connected to the connecting seat 1221, so that medical personnel need to apply a certain external force to the magnetic field generator 200 to make the magnetic field generator 200 rotate, so as to prevent misoperation.

[0065] In an optional embodiment, the lifting lock 13 includes a locking sleeve 131 and a locking button 132 arranged on the locking sleeve 131. The locking sleeve 131 is sleeved on the support rod 22 of the support assembly 20. The locking button 132 is used to limit the locking sleeve 131 to a preset height of the support rod 22, so that the locking sleeve 131 can be driven to move up and down along the support rod 22 according to actual usage requirements, and then the locking sleeve 131 is limited by the locking button 132, which is more convenient to use.

[0066] In an optional embodiment, the lifting lock 13 includes a lifting bushing 133, which is arranged between the locking sleeve 131 and the support rod 22, and is used to increase the damping between the locking sleeve 131 and the support rod 22, overcome the gravity of the magnetic field generator 200 and the joint assembly 10 and prevent them from falling freely.
