In this embodiment, the cross section of the frame 1 is a U-shaped structure. In other embodiments, the specific structure of the frame 1 can be selected according to actual needs and is not specifically limited here. A fixing member 15 for fixing the medical loading device to other devices is also formed on the frame 1. In this embodiment, the fixing member 15 protrudes outward from the third side wall 14, and the fixing member 15 can be connected to the end of the mechanical arm to fix the medical loading device to the end of the mechanical arm. In other embodiments, the fixing member can be set at any position on the frame, and the medical loading device can be fixed to other required devices through the fixing member. Of course, the fixing member 15 can also be set as a gripping portion for holding, so that the medical loading device is a handheld medical loading device. The frame 1 has a first end and a second end located in a first direction, the first end and the second end are two ends of the frame 1, the frame 1 forms a first fixing portion 16 on the first end, and the frame 1 forms a second fixing portion 17 on the second end. The first fixing portion 16 and the second fixing portion 17 can be integrally formed with the frame 1, or can be detachably fixedly connected, which is not specifically limited here and can be selected according to actual needs. The first fixing portion 16 is a hollow ring-like structure, and the structure of the second fixing portion 17 is not specifically limited here.

[0021] A first guiding portion (not labeled) extending in a first direction is provided on the frame body 1. The first guiding portion includes a first screw rod 41 provided on the frame body 1 and extending in the first direction, and a first internal thread hole 22 formed on the sliding body 2 for threaded connection with the first screw rod 41. Specifically, the first screw rod 41 is disposed in the groove 11 of the frame body 1. The first screw rod 41 passes through the first internal thread hole 22 and cooperates with the first internal thread hole 22. By rotating the first screw rod 41, the sliding body 2 having the first internal thread hole 22 can be driven to move relative to the first screw rod 41. In other embodiments, the first internal thread hole 22 may also be formed on a nut, and the nut is mounted on the sliding body 2. One end of the first screw rod 41 is disposed on the second fixing portion 17 at the second end. A third through hole (not shown) through which the first screw rod 41 passes is formed through the second fixing portion 17. The first screw rod 41 can rotate relative to the second fixing portion 17 within the third through hole. And, at the outer side of the second fixing portion 17, one end of the first screw rod 41 is fixedly connected with a first knob 42, so as to facilitate rotating the first screw rod 41. The second knob 52 is convenient to hold and has high operation comfort. The other end of the first screw rod 41 is disposed on the first fixing portion 16 at the first end. A fourth through hole (not shown) through which the first screw rod 41 passes is formed through the first fixing portion 16. The first screw rod 41 can rotate relative to the first fixing portion 16 within the fourth through hole.

[0022] The sliding body 2 is disposed on the first guiding portion. The sliding body 2 can be driven by the first screw rod 41 to move along the first direction on the first screw rod 41. Specifically, the sliding body 2 has a clamping portion 21 clamped on the frame body 1. The clamping portion 21 is clamped on the first side wall 12 and the second side wall 13 and can slide on the first side wall 12 and the second side wall 13. The first screw rod 41 drives the first internal thread hole 22 to move on the first screw rod 41, so that the sliding body 2 connected to the first internal thread hole 22 can move along the first screw rod 41. In order to reduce the volume of the sliding body, the first internal thread hole 22 is disposed at the position where the clamping portion 21 is located within the groove 11.

[0023] The guiding device 3 is used to guide the moving path of the loaded medical devices. A guiding hole 33 for loading the required medical devices is formed through the guiding device 3. The medical devices can be electrode patches, electrode sleeves, puncture devices, drainage devices, etc., but are not limited thereto. The medical devices can also be other required devices. The guiding hole 33 can be set according to the shape of the required medical devices, or can be set to a certain size so that all medical devices can pass through.

[0024] In this embodiment, in addition to guiding the movement path, the guiding device 3 can also carry medical devices thereon and fix the medical devices at the target position of the patient or insert them into the target position of the patient. The guiding device 3 is disposed at the first end of the frame body 1, and the guiding device 3 is disposed on the first fixing portion 16. Specifically, the guiding device 3 is inserted into the first fixing portion 16 and can rotate relative to the first fixing portion 16. In this embodiment, since the guiding device 3 can move between the first position and the second position, the specific structure of the guiding device 3 in this embodiment is: the guiding device 3 includes a fixing member 31 fixed to the first fixing portion 16 and a moving member 32 that can move relative to the fixing member 31. The fixing member 31 is a hollow cylindrical structure with one end closed, and the fixing member 31 is sleeved on the moving member 32. The central axis of the guiding device 3 is the same as the first direction. In other embodiments, the guiding device 3 may not move, that is, it does not have a first position and a second position. It may always form a certain distance from the target position of the patient, or always abut against the target position of the patient, or has already entered the target position of the patient.

[0025] A second guiding portion extending in the first direction is further provided on the frame body 1. The second guiding portion drives the guiding device 3 to move relative to the target position of the patient, that is, the second guiding portion drives the guiding device 3 to move between the first position and the second position. Specifically, the second guiding portion drives the moving member 32 to move relative to the target position of the patient under the action of an external force. In detail, the second guiding portion includes a driving rod 51 disposed on the frame body 1 and extending in the first direction and fixedly connected to the fixing member 31 and a second internal thread hole (not shown) formed in the moving member 32 for threadedly connecting with the fixing member 31. Among them, the fixing member 31 and the moving member 32 are threadedly connected, and the moving member 32 can move along the first direction on the driving rod 51 driven by the driving rod 51. It should be noted that, in other embodiments, the fixing member may not be provided in the guiding device, and the moving member 32 is directly threadedly connected to the driving rod. The driving rod 51 is located above the groove 11. One end of the driving rod 51 is disposed on the second fixing portion 17 at the second end. A first through hole 171 through which the driving rod 51 passes is formed in the second fixing portion 17. The driving rod 51 can rotate relative to the second fixing portion 17 in the first through hole 171. And, outside the second fixing portion 17, one end of the driving rod 51 is fixedly connected to a second knob 52 to facilitate the rotation of the driving rod 51. The second knob 52 is convenient to hold and has a high operating comfort. The sliding body 2 is disposed between the guiding device 3 and the second end. Therefore, the driving rod 51 passes through the sliding body 2. A second through hole 23 through which the driving rod 51 passes is formed in the sliding body 2, and the driving rod 51 can also rotate in the second through hole 23. By rotating the second knob 52, the driving rod 51 drives the fixing member 31 to rotate, and the moving member 32 having the second internal thread hole moves relative to the fixing block 31 at the first end.

[0026] The frame body 1 is further provided with a stopper 6 for stopping the sliding body 2 from moving towards the guiding device 3 at a set position, so as to prevent the medical device from exceeding the position of the patient's lesion. The stopper 6 can move relative to the frame body 1 in the first direction. The method of positioning the stopper 6 at the set position on the frame body 1 can be that the stopper 6 is positioned at the set position on the frame body 1 by a fixing structure, or the stopper 6 is positioned at the set position on the frame body 1 by its own clamping force. There is no specific limitation here, and it can also be other methods that can position the stopper 6 at the set position on the frame body 1, which can be selected according to needs. In this embodiment, the stopper 6 includes a first clamping arm 61 and a second clamping arm 62 which are oppositely arranged, and a fastener 63 that is bolted to the first clamping arm 61 and the second clamping arm 62 to adjust the tightening force of the first clamping arm 61 and the second clamping arm 62 acting on the frame body 1. The first clamping arm 61 and the second clamping arm 62 are respectively clamped on the first side wall 12 and the second side wall 13. By changing the clamping force of the first clamping arm 61 and the second clamping arm 62 on the first side wall 12 and the second side wall 13 respectively through the fastener 63, the stopper 6 can slide on the frame body 1 or be fixed at the required position.

[0027] The frame 1 is also provided with a scale mark 7 extending along the first direction. The scale mark 7 is formed on the first side wall 12 or the second side wall 13. Of course, the scale mark 7 can be formed on both the first side wall 12 and the second side wall 13. Through the scale mark 7, the movement displacement of the sliding body 2 and the stopper 6 can be easily understood, and the movement displacement of the medical equipment set in the medical loading device can be accurately controlled. The medical equipment is set between the guide device 3 and the sliding body 2. Under the action of an external driving force, the sliding body 2 moves toward the guide device 3 on the first guide portion to push the medical equipment to reach the patient's target position through the guide device 3, so that the medical equipment moves toward the patient's target position. In this embodiment, the medical equipment is an electrode sleeve, and an electrode sheet is placed in the electrode sleeve. A cranial hole lock is set on the guide device 3, and the patient's target position is set at the human skull. Specifically, the electrode sleeve equipped with the electrode sheet is arranged between the guide device 3 and the sliding body 2, and one end of the electrode sleeve is fixed to the sliding body 2, and the other end of the electrode sleeve is arranged in the guide hole 33. The stopper 6 is set at the desired position, and the first knob 42 is rotated to rotate the first screw 41, so that the sliding body 2 having the first internal threaded hole 22 that cooperates with the first screw 41 moves in the first direction, so that the electrode sleeve equipped with the electrode sheet moves toward the human head until the sliding body 2 moves to the position of the stopper 6, and the electrode sleeve is inserted into the human head. At this time, one end of the electrode sheet enters the human head and reaches the human lesion. Then, the second knob 52 is rotated to rotate the driving rod 51 and the fixing member 31, so that the moving member 32 having the second internal threaded hole matched with the fixing member 31 moves in the first direction, so that the cranial hole lock moves toward the human skull until the cranial hole lock is fixed at the human skull. At the same time, the cranial hole lock fixes one end of the electrode sheet close to the human skull to the human skull. At this time, one end of the electrode sheet is inserted into the human lesion, and the other end is fixed to the skull by the cranial hole lock. Then, the first knob 42 is rotated to make the sliding body 2 drive the electrode sleeve to move in a direction away from the patient's target position, so that the electrode sleeve is pulled out, thereby completing the implantation of the entire electrode sheet. In this embodiment, the cranial hole lock does not enter the human lesion, but in other embodiments, the guide device may be other implant devices or implant materials such as tablets. At this time, the driving rod drives the guide device to allow the tablet to enter the human lesion. The medical loading device can be used not only in the human skull, but also in other parts of the human body, such as in spinal surgery. The medical loading device is installed at the end of the robotic arm and can realize rapid loading and unloading of medical equipment. The main functions of the device include but are not limited to auxiliary positioning, craniotomy drilling, electrode implantation, and self-service installation of cranial hole locks.In this embodiment, the medical device is an electrode cannula with electrode patches. Since the electrode implantation, which was previously manually performed, is now fully automated by a machine, the surgical risk is significantly reduced, the accuracy of electrode implantation is improved, the implantation time is shortened, and the dependence on doctors for this surgery is greatly reduced. Meanwhile, there is a possibility of performing multiple surgeries simultaneously. Additionally, this device can be used in a magnetic resonance imaging (MRI)-compatible environment, enabling real-time imaging to confirm the surgical progress and the status of electrode implantation.

[0028] In summary, the medical loading device places the medical device between the guiding device and the sliding body. The sliding body moves towards the guiding device under the action of an external driving force to push the medical device through the guiding device to the target position of the patient, thereby realizing the automatic operation of the machine to quickly load and unload the medical device. This significantly reduces the surgical risk, improves the implantation accuracy, shortens the implantation time, and greatly reduces the dependence on doctors for this surgery. Moreover, this device is fully compatible with magnetic resonance imaging and can provide real-time information on the implantation status.

For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.
