DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0036] According to an embodiment of the present invention, a handheld front end is provided. Figures 1 to 14, comprising: a housing 1, the housing 1 having a handheld portion 11, the handheld portion 11 being used for being held by an operator; a power assembly 2, the power assembly 2 being connected to the housing 1, the power assembly 2 having a feed portion 21, the feed portion 21 being movably arranged along a preset direction; a lifting assembly 3, the lifting assembly 3 comprising a first lifting component 31 and a second lifting component 32, the first lifting component 31 and the second lifting component 32 being arranged at intervals, the first lifting component 31 and the second lifting component 32 being both connected to the power assembly 2, and the first lifting component 31 and the second lifting component 32 being movably arranged , the first lifting component 31 and the second lifting component 32 are relatively movably arranged; the rotating component 4, the rotating component 4 has a rotating part 41, the rotating part 41 is rotatably arranged, the rotating part 41 is connected to the lifting component 3, and the rotating part 41 is used to drive the lifting component 3 to rotate; the tracking component 5, the tracking component 5 is connected to the power component 2, and the tracking component 5 is used to indicate the real-time position of the power component 2; the control module, the power component 2, the lifting component 3, the rotating component 4 and the tracking component 5 are all connected to the control module signal, and the control module is used to adjust the moving direction of the feed part 21.

[0037] With this setup, the operator grasps the handheld portion 11 and moves the handheld front end. When the tracking assembly 5 detects that the handheld front end has moved within the pre-set surgical range, the control module controls the rotation assembly 4 and the lifting assembly 3 to adjust the forward direction of the power assembly 2 so that the forward direction of the power assembly 2 coincides with the preset needle insertion direction. The control module then controls the feed unit 21 to move forward, performing the needle insertion operation. In this way, the miniaturized handheld front end adjusts the needle insertion direction through the control module, eliminating the need for manual adjustment of the needle insertion position and angle, thereby improving surgical precision.

[0038] In the handheld front end of this embodiment, see Figures 1 to 3 The lifting assembly 3 includes a first lifting cylinder 33 and a second lifting cylinder 34, which are spaced apart and arranged on the rotating portion 41. The first lifting component 31 is connected to the piston rod of the first lifting cylinder 33, and the second lifting component 32 is connected to the piston rod of the second lifting cylinder 34. The control module is connected to the first lifting cylinder 33 and the second lifting cylinder 34 by signals to control the lifting and lowering of the first lifting cylinder 33 and the second lifting cylinder 34. In this way, when the control module determines that the power assembly 2 needs to be pitched based on the real-time position information of the power assembly 2 transmitted by the tracking component 5, the control module adjusts the pitch angle of the power assembly 2 by controlling the difference in the moving distances of the first lifting cylinder 33 and the second lifting cylinder 34.

[0039] Specifically, see Figure 11 and Figure 12When the power assembly 2 needs to be tilted upward, the rising distance of the first lifting cylinder 33 is greater than the rising distance of the second lifting cylinder 34; when the power assembly 2 needs to be tilted downward, the rising distance of the first lifting cylinder 33 is less than the rising distance of the second lifting cylinder 34.

[0040] In the handheld front end of this embodiment, see Figure 4 、 Figure 5 The first lifting component 31 includes a first connecting plate body 311 and a second connecting plate body 312; there are two first connecting plate bodies 311, and the two first connecting plate bodies 311 are respectively arranged on both sides of the power assembly 2. The two first connecting plate bodies 311 are each provided with a first connecting protrusion 315 on the side close to the power assembly 2, and the first connecting protrusion 315 is rotatably connected to the power assembly 2; the two ends of the second connecting plate body 312 are respectively connected to the two first connecting plate bodies 311, and the side of the second connecting plate body 312 away from the power assembly 2 is connected to the piston rod of the first lifting cylinder body ; The second lifting component 32 includes a third connecting plate body 313 and a fourth connecting plate body 314; there are two third connecting plate bodies 313, and the two third connecting plate bodies 313 are respectively arranged on both sides of the power component 2, and the two third connecting plate bodies 313 are respectively provided with a second connecting protrusion 316 on the side close to the power component 2, and the second connecting protrusion 316 is rotatably connected to the power component 2; the two ends of the fourth connecting plate body 314 are respectively connected to the two third connecting plate bodies 313, and the side of the fourth connecting plate body 314 away from the power component 2 is connected to the piston rod of the second lifting cylinder body. In this way, a first connecting protrusion 315 is inserted on both sides of the power component 2, and the first connecting protrusion 315 is rotatably arranged in the power component 2. Therefore, the first connecting plate body 311 is rotatably arranged relative to the power component 2, and the second connecting plate body 312 is connected to the two first connecting plate bodies 311. When the piston rod of the first lifting cylinder body performs a lifting movement, it drives the second connecting plate body 312 and the two first connecting plate bodies 311 to rotate relative to the power component 2; similarly, when the piston rod of the second lifting cylinder body performs a lifting movement, the third connecting plate body 313 and the fourth connecting plate body 314 also rotate relative to the power component 2.

[0041] In the handheld front end of this embodiment, see Figure 6The power assembly 2 is provided with a connecting groove 26 and a sliding groove 27 on both sides. The sliding groove 27 extends along the axis of the power assembly 2. The first connecting protrusion 315 is relatively rotatably connected to the connecting groove 26. The second connecting protrusion 316 is relatively rotatably connected to the sliding groove 27. The second connecting protrusion 316 is movably arranged in the sliding groove 27. In this way, when the power assembly 2 needs to be pitched, the first connecting protrusion 315 rotates in the connecting groove 26, and the second connecting protrusion 316 rotates in the sliding groove 27 while moving along the sliding groove 27. The connecting groove 26 and the sliding groove 27 can generate a height difference through the lifting and lowering movement of the first and second lifting cylinders, thereby completing the pitch adjustment of the power assembly 2.

[0042] In the handheld front end of this embodiment, see Figure 7The handheld front end also includes a supporting structure 6, which includes: a first supporting part 61 and a second supporting part 62, the first supporting part 61 and the second supporting part 62 are arranged at intervals, and the first supporting part 61 has a first axis 611 and a second axis 612 arranged at intervals on the side close to the second supporting part 62, and the second supporting part 62 has a third axis and a fourth axis arranged at intervals on the side close to the first supporting part 61; the two first connecting plates 311 are respectively provided with a first moving channel 3111 and a third moving channel 3112, the first moving channel 3111 is used for the first axis 611 to pass through, and the third moving channel 3112 is used for the third axis to pass through; the two third connecting plates 313 are respectively provided with a second moving channel 3131 and a fourth moving channel 3132, the second moving channel 3131 is used for the second axis 612 to pass through, and the fourth moving channel 3132 is used for the fourth axis to pass through. In this way, the support structure 6 is sleeved on the outside of the first lifting component 31 and the second lifting component 32. The first lifting component 31 is movably connected to the support structure 6 through the first shaft 611 and the third shaft, and the second lifting component 32 is movably connected to the support structure 6 through the second shaft 612 and the fourth shaft. At the same time, the first shaft 611 and the third shaft are connected to the first lifting component 31 through the first moving channel 3111 and the third moving channel 3112 respectively. The first shaft 611 passes through the first moving channel 3111, and the third shaft passes through the third moving channel 3112, so that the first lifting component 31 can be moved freely. The lifting component 31 can only move relative to the support structure 6 along the extension direction of the first axis 611 and the third axis, and plays a limiting role in other directions; the second axis 612 and the fourth axis are connected to the second lifting component 32 through the second moving channel 3131 and the fourth moving channel 3132 respectively, and the second axis 612 passes through the second moving channel 3131, and the fourth axis passes through the fourth moving channel 3132, so that the second lifting component 32 can only move relative to the support structure 6 along the extension direction of the second axis 612 and the fourth axis, and plays a limiting role in other directions.

[0043] Preferably, rollers are provided in the first moving channel 3111 , the third moving channel 3112 , the second moving channel 3131 and the fourth moving channel 3132 .

[0044] In the handheld front end of this embodiment, see Figure 7The third support member 63 has one end connected to the first support member 61 and the other end connected to the second support member 62. A connecting portion 631 is provided on the side of the third support member 63 away from the first and second support members 61, 62. The connecting portion 631 is rotatably connected to the handheld portion 11. The third support member 63 has a lifting passage for the first and second lifting members 31, 32 to pass through. In this way, the first and second lifting members 31, 32 are movably connected to the support structure 6, allowing them to move in the lifting direction within the support structure 6.

[0045] Preferably, a bearing is provided between the connecting portion 631 and the handle portion 11. In this way, the bearing not only lubricates the rotation between the connecting portion 631 and the handle portion 11, but also limits the movement of the first lifting component 31 and the second lifting component 32 in directions other than the lifting direction.

[0046] In the handheld front end of this embodiment, see Figure 1 、 Figure 3 The rotating assembly 4 includes a rotating motor, which is connected to the control module signal, the control module is used to control the rotation of the rotating motor, and the rotating part 41 is driven and connected to the rotating motor; the rotating part 41 includes: a rotating plate 411, the rotating plate 411 is connected to the motor shaft of the rotating motor; a fixed plate 412, the fixed plate 412 is arranged on the rotating plate 411, and the two sides of the fixed plate 412 are respectively provided with a first fixing part 4121 for fixing the first lifting component 31 and a second fixing part 4122 for fixing the second lifting component 32. In this way, when the control module determines that the power component 2 needs to rotate to adjust the moving direction of the feed part 21, the rotating motor drives the rotating part 41 to rotate around the rotating axis of the rotating motor, and the fixed plate 412 fixes the first lifting component 31 and the second lifting component 32 on the rotating part 41. When the rotating part 41 rotates around the motor axis, it drives the first lifting component 31 and the second lifting component 32 to rotate together. The first lifting component 31 and the second lifting component 32 drive the power component 2 to rotate along the motor axis to complete the adjustment of the moving direction of the feed part 21.

[0047] Specifically, see Figure 13 and Figure 14 When the power assembly 2 needs to be rotated and adjusted, the rotating motor drives the fixed plate 412 to rotate as a whole through the rotating plate 411.

[0048] In the handheld front end of this embodiment, see Figure 1 、 Figure 3 、 Figure 8The power assembly 2 includes: a sleeve 22, which has a mounting cavity 221 therein, the sleeve is rotatably connected to the first lifting component 31, the sleeve 22 is rotatably connected to the second lifting component 32, and the sleeve 22 is movably connected to the second lifting component 32; a movable rail 23, which is arranged on the side of the sleeve close to the mounting cavity 221, and the extension direction of the movable rail 23 is the same as the axial direction of the mounting cavity 221; a feed cylinder 24, which is arranged in the mounting cavity 221, and the feed part 21 is arranged on the shaft of the feed cylinder 24, and the feed cylinder 24 drives the feed part 21 to move along the movable rail 23. In this way, the feed cylinder 24 is arranged in the mounting cavity 221. When the control module adjusts the axis of the power assembly 2 to coincide with the preset axis, the control module controls the feed cylinder 24 to push the feed part 21 to feed along the movable rail 23, and the movable rail 23 guides the feeding of the feed part 21.

[0049] In the handheld front end of this embodiment, see Figure 1 、 Figure 3 、 Figure 8 The end of the movable rail 23 away from the feed cylinder 24 is provided with a mounting portion 25, and the feed unit 21 is disposed within the mounting portion 25. A first limiting portion 251 is provided on the side of the mounting portion 25 close to the feed cylinder 24, and a second limiting portion 252 is provided on the side of the mounting portion 25 away from the feed cylinder 24. The first limiting portion 251 and the second limiting portion 252 are used to limit the movement of the feed unit 21. In this way, the mounting portion 25 is mounted on the movable rail 23, and the feed unit 21 moves within the mounting portion 25, which can improve the smoothness of movement and feeding accuracy of the feed unit 21.

[0050] Specifically, see Figure 3 When the power assembly 2 needs to be fed, the feed cylinder 24 pushes the feed part 21 to move in the mounting part 25 to achieve feeding. The mounting part 25 is installed on the moving track 23 to ensure smooth movement and structural accuracy.
