Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and specifically relates to a tracer connection device for humeral intramedullary nail surgery. Background Art

[0002] The surgical navigation system is based on medical imaging data such as MRI and CT. It accurately matches the patient's preoperative or intraoperative imaging data with the patient's anatomical structure on the operating table, tracks surgical instruments during surgery, and updates the position of surgical instruments in real time on the patient's image in the form of a virtual probe, allowing medical staff to understand the position of the instrument relative to the patient. This helps medical staff understand whether the movement path of the surgical instrument will cause additional damage to the human body, and helps medical staff determine that the surgical instrument has reached the lesion location, making the surgery safer and faster, and greatly reducing the patient's pain during the operation.

[0003] When using a surgical navigation system, it is necessary to set a tracer on the surgical instrument. The tracer helps the surgical navigation system establish a reference system, thereby assisting the surgical navigation system to understand the position of the surgical instrument relative to the patient in real time, and helps the surgical navigation system establish the surgical path of the surgical instrument in the patient's body, helping medical staff to dynamically understand the progress of the operation, and can accurately determine the relative position between the surgical instrument and the lesion, greatly improving the accuracy of the medical staff's operation, making the operation faster and more precise.

[0004] Intramedullary nails are orthopedic internal fixation devices among medical devices. They use closed and minimally invasive techniques to reduce the infection rate of surgery. The firm fixation of intramedullary nails allows for early functional exercise and weight-bearing. In addition, the incision required for removing the intramedullary nail is small, and the skin is easy to heal.

[0005] The humerus is the thickest bone in the upper limb. The upper end forms the shoulder joint with the scapula, and the lower end forms the elbow joint with the radius and ulna. When performing humeral intramedullary nail surgery on different patients, medical staff sometimes need to operate on the left humerus, and sometimes need to operate on the right humerus. In this process, if the position of the tracer relative to the surgical instrument is fixed, when facing different patients, the position of the tracer will limit the spatial posture of the surgical instrument and the surgical space. Therefore, the tracer needs to be installed on different sides of the intramedullary nail to meet the needs of different patients. During the operation, it is necessary to ensure that the intramedullary nail can enter the bone marrow cavity smoothly as much as possible, and the intramedullary nail cannot rotate during the process of entering the bone marrow cavity to avoid affecting the placement of the locking nail. Therefore, the stability of the tracer installation directly affects the operation of medical staff. Utility Model Content

[0006] In order to ensure the stability of the tracer installed on the intramedullary nail bracket and ensure the normal progress of the operation, the present application discloses a tracer connecting device for humeral intramedullary nail surgery.

[0007] A tracer connecting device for humeral intramedullary nail surgery can be installed on a fixing frame installed with an intramedullary nail, the fixing frame is provided with a fixing plate in the same direction as the extension of the intramedullary nail, and the fixing plate is provided with a fixing plane in the same direction as the extension of the intramedullary nail; the tracer connecting device for humeral intramedullary nail surgery is characterized in that it includes a connecting plate and a wing connected to the connecting plate; the connecting plate is provided with a connecting plane which can be detachably connected to the fixing plane to fix the tracer connecting device for humeral intramedullary nail surgery to the fixing frame, wings are provided on both sides of the connecting plate, and a tracer connecting rod can be fixedly connected to the wings on one side of the connecting plate, so that the tracer can be connected to the fixing frame through the tracer connecting rod and the tracer connecting device for humeral intramedullary nail surgery, and the end of the tracer connecting rod on which the tracer is installed can face the side of the extension direction of the intramedullary nail.

[0008] The connecting plate is connected to the fixing plate through the connecting plane and the fixing plane. The tracer can be fixed to the fixing frame through the connecting plate, thereby realizing the connection between the tracer and the intramedullary nail. The connection degree between the connecting plate and the fixing frame is improved by combining the connecting plane and the fixing plane. When taking the fixing frame with the tracer and the intramedullary nail installed, or shaking or rotating it at multiple angles, the connecting plane and the fixing plane can provide sufficient support, thereby avoiding the displacement of the tracer or the rotation around the intramedullary nail, so that the tracer can accurately feedback the spatial position, spatial posture and other information of the intramedullary nail. At the same time, The combination of the connecting plane and the fixing plane can greatly ensure the connection stability between the tracer connecting device for humeral intramedullary nail surgery and the fixing frame, thereby greatly ensuring the operating feel of medical staff during surgery. When performing surgery on the left or right humerus of the patient, one of the wings on both sides of the connecting plate can be selected for connection according to usage requirements. The connecting plane and the fixing plane are combined to fix the tracer to the fixing frame through the tracer connecting device for humeral intramedullary nail surgery. This can ensure that even if different wings are switched, the stability of the connection between the tracer and the fixing frame can still be guaranteed.

[0009] In one embodiment of the present application, the fixing plane is perpendicular to the line between the fixing plate and the intramedullary nail, and the fixing plane is arranged on the side of the fixing plate away from the intramedullary nail; the wings on both sides of the connecting plate are arranged on the side of the connecting plane away from the intramedullary nail.

[0010] The fixing plane is perpendicular to the line between the fixing plate and the intramedullary nail, and the fixing plane is arranged on the side of the fixing plate away from the intramedullary nail, that is, the fixing plane is at the outermost side, and the wings on both sides of the connecting plate are arranged on the side of the connecting plane away from the intramedullary nail, thereby facilitating the installation of the tracer connecting device for the humeral intramedullary nail surgery on the fixing frame, and when the fixing plane is above the intramedullary nail, the fixing plane can bear the tracer connecting device for the humeral intramedullary nail surgery, thereby facilitating the installation of the tracer connecting device for the humeral intramedullary nail surgery on the fixing plane.

[0011] In one embodiment of the present application, a connecting line between the fixing plate and the intramedullary nail forms a reference plane, the connecting plane is provided with a connecting hole, the fixing plane is provided with a fixing hole, and when the connecting plane is connected to the fixing plane, the axis of the connecting hole is located in the reference plane; the fixing member passes through the connecting hole and is connected to the fixing hole to fix the connecting plate to the fixing plate.

[0012] The connecting hole is arranged on the connecting plate, and the connecting plate is located between the two wings. The fixing piece can pass through the connecting hole between the two wings and be connected with the fixing hole on the fixing plane, so there is no need to specially set up an additional structure to set up the connecting hole, thereby saving the installation space required for installing the tracer connecting device for humeral intramedullary nail surgery on the fixing frame, and at the same time providing convenience for the installation of the tracer.

[0013] In one embodiment of the present application, a connecting plane is provided with a connecting hole that passes through the connecting plate; a fixing plane is provided with a fixing hole, and the fixing hole is provided with an internal thread; the tracer connection device for humeral intramedullary nail surgery also includes a fastening bolt, the fastening bolt includes a bolt head, a bolt connecting section, and a bolt threaded section connected in sequence, the bolt threaded section is provided with a thread that matches the fixing hole, the bolt head and the bolt connecting section are detachably connected, the diameters of the bolt head and the bolt threaded section are larger than the diameter of the connecting hole, the diameter of the bolt connecting section is not larger than the diameter of the connecting hole, the bolt connecting section can pass through the connecting hole and be detachably connected to the bolt head, and the combined action of the bolt head and the bolt threaded section can limit the connecting plate to the bolt connecting section.

[0014] The bolt head and the bolt thread section can limit the connecting plate to the bolt connecting section, so that during installation, only the bolt head can be taken to pick up the entire tracer connecting device for humeral intramedullary nail surgery, and then the tracer connecting device for humeral intramedullary nail surgery can be installed on the fixing plate by using the thread cooperation of the bolt thread section and the fixing hole, thereby reducing assembly time, improving assembly efficiency, and reducing patient waiting time; at the same time, it avoids the scattering of parts and ensures surgical safety.

[0015] In one embodiment of the present application, the wing portion is integrally formed with the connecting plate, and the wing portion is provided with a mounting hole for inserting a tracer rod, with the opening of the mounting hole facing outward; after the tracer rod is inserted into the mounting hole located on the left or right side of the connecting plate, one end of the tracer of the tracer rod can face one side of the intramedullary nail, so that when the tracer rod is inserted into the mounting hole located on the left side of the connecting plate, the intramedullary nail can perform surgery on the humerus of the arm located on the right side of the connecting plate, so that when the tracer rod is inserted into the mounting hole located on the right side of the connecting plate, the intramedullary nail can perform surgery on the humerus of the arm located on the left side of the connecting plate.

[0016] In one embodiment of the present application, an observation groove connected to the mounting hole is opened on the upper surface of the wing. After the tracer connecting rod is inserted into the mounting hole, the movement of the bottom end of the tracer connecting rod in the mounting hole can be observed through the observation groove.

[0017] Through the observation slot, when the medical staff operates the intramedullary nail, they can observe whether the tracer connecting rod moves, rotates, etc., to ensure the accuracy of the information such as the position and posture of the intramedullary nail fed back by the tracer; at the same time, the setting of the observation slot reduces the weight of the tracer connecting device for humeral intramedullary nail surgery, thereby facilitating the medical staff to operate the intramedullary nail. Preferably, the observation slot runs through the wing portion to ensure that there is enough light entering the observation slot, so as to facilitate the medical staff to observe the movement of the bottom end of the tracer connecting rod, thereby ensuring the accuracy of the information about the intramedullary nail fed back by the tracer.

[0018] In one embodiment of the present application, a depth scale is provided on the edge of the slot of the observation slot, and the depth scale is arranged along the depth direction of the mounting hole to determine the depth position of the bottom end of the tracer connecting rod in the mounting hole according to the depth scale.

[0019] Medical personnel can refer to the depth scale to observe the movement of the bottom end of the tracer connecting rod along the mounting hole.

[0020] In one embodiment of the present application, the tracer connection device for humeral intramedullary nail surgery also includes a locking bolt, and the wing portion is also provided with a locking threaded hole that is connected to the side wall of the mounting hole and can be threadedly matched with the locking bolt; after the tracer connecting rod is inserted into the mounting hole, the locking bolt can threadably match with the locking threaded hole and squeeze the side wall of the tracer connecting rod in the mounting hole to fix the tracer connecting rod in the mounting hole.

[0021] The locking bolt is pressed against the side wall of the tracer connecting rod, and the friction between the locking bolt, the mounting hole and the tracer connecting rod is used to fix the tracer connecting rod in the mounting hole. The insertion depth of the tracer connecting rod into the mounting hole can be adjusted arbitrarily to adjust the relative distance between the tracer and the intramedullary nail, thereby meeting the space requirements of different surgeries.

[0022] In one embodiment of the present application, a straight observation hole communicating with the side wall of the locking threaded hole is also provided on the surface of the wing portion.

[0023] When removing the locking bolt from the locking threaded hole to release the restriction of the locking bolt on the tracer connecting rod, the position of the locking bolt in the locking threaded hole can be observed by observing the straight hole, and the rotation of the locking bolt can be stopped as appropriate, thereby releasing the restriction of the locking bolt on the tracer connecting rod while avoiding the locking bolt from being completely removed from the locking threaded hole. The locking bolt is still connected to the wing, thereby facilitating the subsequent parts management and avoiding medical accidents.

[0024] In one embodiment of the present application, along the depth direction of the locking threaded hole, the locking threaded hole includes a threaded section provided with threads, an observation section connected to the observation straight hole, and a connecting section connected to the side wall of the mounting hole; the threaded section can cooperate with the locking bolt thread, and along the depth direction of the locking threaded hole, the threaded section, the observation section, and the connecting section are connected in sequence.

[0025] The threaded section of the locking threaded hole ensures the connection between the locking bolt and the wing after the locking bolt passes through the position of the observation straight hole, thereby preventing the locking bolt from falling off the wing and ensuring the safety of the operation.

Of course, those skilled in the art of the present application can understand that there are many ways to achieve the detachable connection between the connecting plane 105 and the fixing plane 2011 in the present application. For example, the connecting hole 1011 and the fixing hole 2012 are through holes, and a pin is used to pass through the connecting hole 1011 and the fixing hole 2012, so as to achieve the detachable connection between the connecting plane 105 and the fixing plane 2011.

[0057] See also Figure 6 In one embodiment of the present application, a depth scale 106 is provided at the edge of the slot of the observation slot 1022 , and the depth scale 106 is arranged along the depth direction of the mounting hole 1021 to determine the depth position of the bottom end of the tracer connecting rod 501 in the mounting hole 1021 according to the depth scale 106 .

[0058] Medical personnel can observe the movement of the bottom end of the tracer connecting rod 501 along the mounting hole 1021 with reference to the depth scale 106 .

[0059] See also Figure 1 , Figure 2 , Figure 6In one embodiment of the present application, the tracer connecting device 1 for humeral intramedullary nail surgery also includes a locking bolt 104, and the wing 102 is also provided with a locking threaded hole 103 which is connected to the side wall of the mounting hole 1021 and can be threadedly matched with the locking bolt 104; after the tracer connecting rod 501 is inserted into the mounting hole 1021, the locking bolt 104 can be threadedly matched with the locking threaded hole 103 and squeeze the side wall of the tracer connecting rod 501 in the mounting hole 1021 to fix the tracer connecting rod 501 in the mounting hole 1021.

[0060] See also Figure 6 In one embodiment of the present application, a straight observation hole 1023 communicating with the side wall of the locking threaded hole 103 is further provided on the surface of the wing 102 .

[0061] Medical staff can observe the position of the locking bolt 104 by observing the straight hole 1023 to determine that the locking bolt 104 is effectively against the side wall of the tracer connecting rod 501; when removing the locking bolt 104 from the locking threaded hole 103 to release the restriction of the locking bolt 104 on the tracer connecting rod 501, the position of the locking bolt 104 in the locking threaded hole 103 can be observed by observing the straight hole 1023, and the rotation of the locking bolt 104 can be stopped as appropriate, thereby releasing the restriction of the locking bolt 104 on the tracer connecting rod 501 and avoiding the locking bolt 104 from being completely removed from the locking threaded hole 103. The locking bolt 104 is still connected to the wing 102, thereby facilitating the subsequent parts management and avoiding medical accidents.

[0062] See also Figure 6 In one embodiment of the present application, along the depth direction of the locking threaded hole 103, the locking threaded hole 103 includes a threaded section 1031 provided with threads, an observation section 1032 connected to the observation straight hole 1023, and a connecting section 1033 connected to the side wall of the mounting hole 1021; the threaded section 1031 is provided with threads matching the locking threaded hole 103, and along the depth direction of the locking threaded hole 103, the threaded section 1031, the observation section 1032, and the connecting section 1033 are connected in sequence, and the observation section 1032 is located between the connecting section 1033 and the threaded section 1031.

[0063] The threaded section 1031 provided in the locking threaded hole 103 ensures that the locking bolt 104 is still threadedly connected to the wing 102 after the locking bolt 104 passes through the observation straight hole 1023, thereby preventing the locking bolt 104 from falling off the wing 102 and ensuring surgical safety.
