In order to reduce the volume of the sliding body, the motor and the turbine are installed at the position where the clamping part 21 is located in the groove 11.

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

[0024] In this embodiment, in addition to guiding the moving path, the guide device 3 can also be loaded with medical equipment, and the medical equipment is fixed at the patient's target position or inserted into the patient's target position. The guide device 3 is arranged at the first end of the frame 1, and the guide device 3 is arranged on the first fixing portion 16. Specifically, the guide device 3 is inserted and fixed in the first fixing portion 16 and can rotate relative to the first fixing portion 16. In this embodiment, since the guide device 3 can move between the first position and the second position, the specific structure of the guide device 3 in this embodiment is: the guide 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 guide device 3 is the same as the first direction. In other embodiments, the guide device 3 may not move, that is, it does not have a first position and a second position, and it can always form a certain distance between the patient's target position, or always abut against the patient's target position, or have entered the patient's target position.

[0025] The frame 1 is also provided with a second guide portion extending along the first direction, and the second guide portion drives the guide device 3 to move relative to the patient's target position, that is, the second guide portion drives the guide device 3 to move between the first position and the second position. Specifically, the second guide portion drives the movable member 32 to move relative to the patient's target position under the action of an external force. In detail, the second guide portion includes a driving rod 51 arranged on the frame 1 and extending along the first direction and fixedly connected to the fixed member 31, and a second internal threaded hole (not shown) formed in the movable member 32 to be threadedly connected to the fixed member 31, wherein the fixed member 31 and the movable member 32 are threadedly connected, and the movable member 32 can be driven by the driving rod 51 to move along the first direction on the driving rod 51. Of course, in other embodiments, the fixed member may not be provided in the guide device, and the movable member 32 is directly threadedly connected to the driving rod. The driving rod 51 is located above the groove 11, and one end of the driving rod 51 is arranged on the second fixing part 17 of the second end. The second fixing part 17 is formed with a first through hole 171 for the driving rod 51 to pass through. The driving rod 51 can rotate relative to the second fixing part 17 in the first through hole 171, and, located at the outer side of the second fixing part 17, one end of the driving rod 51 is fixedly connected with a knob 52, so as to facilitate the rotation of the driving rod 51. The knob 52 is easy to hold and has high comfort in operation. The sliding body 2 is arranged between the guide device 3 and the second end, so that the driving rod 51 passes through the sliding body 2, and the sliding body 2 is formed with a second through hole 22 for the driving rod 51 to pass through. The driving rod 51 can also rotate in the second through hole 22. By rotating the knob 52, the driving rod 51 drives the fixing member 31 to rotate, and the moving member 32 with the second internal threaded hole moves relative to the fixing block 31 on the first end.

[0026] The frame 1 is also provided with a stopper 6 for stopping the sliding body 2 from moving toward the guide device 3 at the set position, so as to prevent the medical equipment from exceeding the patient's lesion position. The stopper 6 can move relative to the frame 1 along the first direction. The method for positioning the stopper 6 at the set position of the frame 1 can be that the stopper 6 is positioned at the set position of the frame 1 by a fixed structure, or the stopper 6 is positioned at the set position of the frame 1 by its own holding force. No specific limitation is made here. Other methods that can position the stopper 6 at the set position of the frame 1 can also be used, which can be selected as needed. In this embodiment, the stopper 6 includes a first clamping arm 61 and a second clamping arm 62 that are arranged opposite to each other, and a fastener 63 that is bolted to the first clamping arm 61 and the second clamping arm 62 to adjust the tension of the first clamping arm 61 and the second clamping arm 62 acting on the frame 1. The first clamping arm 61 and the second clamping arm 62 are clamped on the first side wall 12 and the second side wall 13 respectively, and 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 is changed by the fastener 63, so as to realize the sliding of the stopper 6 on the frame 1 or fixation at a 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 the driving member, the sliding body 2 moves toward the guide device 3 on the first guide part 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 target object. 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 on the sliding body 2, and the other end of the electrode sleeve is arranged in the guide hole 33, and the stopper 6 is set at the required position. The motor drives the turbine to move on the rack 41, so that the sliding body 2 connected to the motor and the turbine 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, and then, the rotation The knob 52 is turned to rotate the driving rod 51 and the fixing member 31, so that the moving member 32 with the internal threaded hole matching 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 motor is started to drive the sliding body 2 to move the electrode sleeve 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.

[0028] The medical loading device is installed at the end of the robotic arm and can realize the 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, self-service installation of cranial hole locks, etc. In this embodiment, the medical equipment is an electrode sleeve with an electrode sheet. Since the electrode implantation is completely completed automatically by the machine instead of the existing manual implantation, the surgical risk is greatly reduced, the accuracy of electrode implantation is improved, and the implantation time is shortened. It also greatly reduces the degree of dependence of the operation on doctors, and is expected to carry out the possibility of multiple operations at the same time. At the same time, the device can be used for surgery in a nuclear magnetic compatible environment, and imaging can be performed at any time to confirm the progress of the operation and to clearly understand the status of the electrode implantation. It should be noted that the control part in this embodiment is connected to the control module of the robotic arm after all the cables are led out, and the control module realizes the control of the medical loading device.

[0029] The medical loading device shown in the second embodiment of the present invention is basically the same as the medical loading device shown in the first embodiment, except that in this embodiment, the driving member is arranged at the second end of the frame, and the driving member is a motor. The first guide portion is a driving screw connected to the motor, and a sliding nut matched with the driving screw, and the sliding nut is arranged in the clamping portion of the sliding body. The driving screw connected to the motor is driven by the frame, and the sliding nut is driven to move by the rotation of the driving screw, thereby driving the sliding body to move in the first direction.

[0030] In summary, the medical loading device sets the medical equipment between the guide device and the sliding body. The sliding body moves toward the guide device under the action of the driving member to push the medical equipment through the guide device to reach the patient's target position, thereby realizing automatic operation of the machine to complete the rapid loading and unloading of medical equipment, greatly reducing surgical risks, improving implantation accuracy, shortening implantation time, and greatly reducing the degree of dependence of the operation on doctors. At the same time, the device is fully compatible with magnetic resonance imaging and can understand the status of the implant in real time.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
