[0035] The utility model provides a slotting device for a surgical instrument.

[0036] In one embodiment of the present utility model, reference Figure 1 , Figure 2 , Figure 5 , the slotting device of the surgical instrument comprises:

[0037] The workbench 100 has a processing area 110, and the processing area 110 is used for placing a workpiece to be processed, wherein the workpiece to be processed is a surgical instrument.

[0038] The multi-axis driving member 200 is fixedly mounted on the workbench 100 . In the present embodiment, there is no limitation on the structure of the multi-axis driving member 200 , wherein the multi-axis driving member 200 may be a multi-axis robot arm or other structures.

[0039] The laser etching assembly 300 includes a laser generator 310, which is used to produce a high-intensity, high-energy-density laser beam; the laser generator 310 is located above the processing area 110 and is installed on the multi-axis driving member 200, and the multi-axis driving member 200 is used to drive the laser generator 310 to move so that the laser beam generated by the laser generator 310 grooves the surface of the workpiece to be processed. The laser etching assembly 300 also includes a control system and an optical system. The control system is used to control the setting and adjustment of parameters such as the energy output, pulse frequency, and scanning speed of the laser beam; the control system can also be connected to the multi-axis driving member 200 to control the multi-axis driving member 200 so that the multi-axis driving member 200 drives the laser generator 310 to move. The optical system includes a focusing lens, a beam expander, and other auxiliary optical elements, which are used to guide and concentrate the laser beam so that it can form a sufficiently small focus on the target material to achieve high-precision local heating or direct ablation. In this embodiment, when a laser generator 310 is used to open grooves 700 of different specifications on the surface of a surgical instrument 800, it is only necessary to adjust the energy output, pulse frequency and position of the laser generator 310 to open grooves 700 of different specifications without replacing the laser generator 310. This is more convenient than the method of opening grooves 700 of different specifications on a surgical instrument 800 by replacing a milling cutter in the prior art, and the operation is very simple, thereby being able to solve the technical problems existing in the prior art.

[0040] The smoke exhaust assembly 400 includes a negative pressure hood 410, which is installed on the multi-axis driving member 200 and covers the laser generator 310. In the present embodiment, when the laser generator 310 emits a laser beam to open a groove 700 on the surgical instrument 800, the negative pressure hood 410 generates negative pressure to absorb the smoke generated by the laser generator 310 during the etching process, thereby preventing the laser generator 310 from causing the smoke to diffuse over a large range during the etching of the groove 700, thereby affecting the processing environment.

[0041] The technical solution of the utility model adopts a laser generator 310 to open a groove 700 on a surgical instrument 800. When the specifications of the opened grooves 700 are different, the laser generator 310 can be used to open different grooves 700 by adjusting the energy output, pulse frequency and position of the laser generator 310 without replacing the laser generator 310. Compared with the method of opening grooves 700 of different specifications on a surgical instrument 800 by replacing a milling cutter in the prior art, the utility model is more convenient and very simple to operate, thereby being able to solve the technical problems existing in the prior art.

[0042] In one embodiment, reference Figure 1 , Figure 2, Figure 5 The multi-axis driving member 200 includes a first mounting frame 210, a first driving member 220, a second driving member 230 and a rotating member 240. The first mounting frame 210 is fixed to the workbench 100, the first driving member 220 is installed on the first mounting frame 210, and the second driving member 230 is installed on the first driving member 220. The first driving member 220 is used to drive the second driving member 230 to move along the st1 direction. The st1 direction is as shown in FIG. Figure 2 As shown in the st1 direction, the rotating member 240 is installed on the second driving member 230, and the second driving member 230 is used to drive the rotating member 240 to move along the st2 direction. Figure 2 As shown in the st2 direction, the laser generator 310 is installed on the rotating member 240, and the rotating member 240 is used to drive the laser generator 310 to rotate around the axis direction of the output end of the rotating member 240, wherein the st1 direction and the st2 direction are perpendicular to each other. When the first driving member 220 drives the second driving member 230 to move, it can also drive the rotating member 240 and the laser generator 310 to move; when the second driving member 230 drives the rotating member 240 to move, it can also drive the laser generator 310 to move. In this way, the multi-axis drive of the laser generator 310 is realized by the first driving member 220, the second driving member 230 and the rotating member 240. In this embodiment, the first driving member 220 and the second driving member 230 are both configured as motor guide rail slide modules, and the rotating member 240 is configured as a first driving motor; wherein, the guide rail in the first driving member 220 is fixed to the first mounting frame 210, the guide rail in the second driving member 230 is fixed to the slide in the first driving member 220, the first driving motor is fixed to the slide in the second driving member 230, and the laser generator 310 is installed at the output end of the first driving member 220; the use of the above structure can further reduce the cost of the multi-axis driving member 200, and the manufacturing cost is lower than that of a multi-axis robotic arm.

[0043] In one embodiment, reference Figure 1 , Figure 2 , Figure 5The negative pressure cover 410 is provided with a through hole for the output end of the first drive motor to pass through, and the output end of the specific first motor is clearance-matched with the through hole on the negative pressure cover 410, the purpose of which is to avoid the output end of the first drive motor from contacting with the negative pressure cover 410 and generating friction during the rotation process; the negative pressure cover 410 is connected to the slide in the second drive member 230, the purpose of which is to enable the negative pressure cover 410 to move with the second drive member 230 when the second drive member 230 drives the slide to move the rotating member 240 and the laser generator 310 toward the workpiece to be processed to adjust the processing position of the laser generator 310; avoid the situation where the laser generator 310 is close to the workpiece to be processed, while the negative pressure cover 410 is far from the workpiece to be processed, resulting in the problem that the smoke generated by the laser generator 310 when etching the groove body 700 cannot be well adsorbed by the negative pressure cover 410. In this embodiment, the connection method between the negative pressure cover 410 and the slide in the second driving member 230 can adopt the following structure, wherein the slide in the second driving member 230 is connected to the negative pressure cover 410 through a connecting rod 500, wherein the connecting rod 500 and the slide in the second driving member 230 are connected in a fixed manner, and the connecting rod 500 and the negative pressure cover 410 are connected in a fixed manner, so that the negative pressure cover 410 can be more stable when following the movement of the slide in the second driving member 230; further, the fixed connection method between the connecting rod 500 and the slide in the second driving member 230 and the connecting rod 500 and the negative pressure cover 410 can be connected by screw locking, or fixed by bolt and nut connection.

[0044] In one embodiment, reference Figure 2 , Figure 5 , Figure 6 There are multiple laser generators 310, and a second mounting frame 600 is installed on the output end of the rotating member 240. The second mounting frame 600 is used for installing multiple laser generators 310. In this embodiment, the efficiency of opening the groove body 700 on the surgical instrument 800 can be further improved under the action of multiple laser generators 310.

[0045] In this embodiment, reference Figure 4 , Figure 5The second mounting frame 600 can adopt the following structure, the second mounting frame 600 includes a first mounting plate 610 and a plurality of second mounting plates 620, the first mounting plate 610 is connected to the output end of the rotating member 240, and the plurality of second mounting plates 620 are evenly distributed on the outside of the first mounting plate 610 around the axis of the output end of the rotating member 240, and there is a preset angle between the second mounting plate 620 and the first mounting plate 610, and the specific first mounting plate 610 is parallel to the ground plane, so that the laser beam emitted by the laser generator 310 installed on the first mounting plate 610 can be set vertically to the ground, that is, the laser beam emitted by the laser generator 310 installed on the first mounting plate 610 can be vertical to the surgical instrument 800, and its main purpose is to facilitate the initial opening of the slot body 700. Since there is a preset angle between the second mounting plate 620 and the first mounting plate 610, and the preset angle is preferably 45°, under this structure, the laser beam generated by the laser generator 310 mounted on the second mounting plate 620 can be tilted, and the inner wall of the tank body 700 can be processed conveniently under the action of the tilted laser beam, so as to process the tank body 700 structure that meets the requirements. Since the second mounting plate 620 is set to multiple, the laser generator 310 installed on the second mounting plate 620 is also multiple. When it is necessary to open an annular groove 710 on the inner wall of the tank body 700, multiple laser generators 310 installed on the second mounting plate 620 work simultaneously, and then the rotating member 240 drives the second mounting frame 600 to rotate, so that the second mounting plate 620 rotates, thereby accelerating the time of opening the annular groove 710 on the inner wall of the tank body 700, and further improving the processing efficiency; specifically, refer to Figure 6 First, one of the laser generators 310 emits an L1 laser beam toward the surgical instrument 800, so that the surgical instrument 800 opens the outline of the slot body 700, and then another laser generator 310 emits an L2 laser beam and an L3 laser beam toward the inside of the slot body 700, and drives the second mounting frame 600 to rotate under the action of the rotating member 240. At this time, the L2 laser beam and the L3 laser beam can move on the inner wall of the slot body 700 and open the annular groove 710. Since the L2 laser beam and the L3 laser beam process the slot body 700 at the same time, the rotation amplitude of the second mounting frame 600 can be reduced at this time, and the rotation amplitude of the second mounting frame 600 is prevented from being too large, resulting in the wiring harness connected to the laser generator 310 being wound together. In this embodiment, the number of the plurality of second mounting plates 620 can be two, three, or four.

[0046] In one embodiment, the second mounting plate 620 is hinged to the first mounting plate 610 by bolts and nuts (not shown). In this embodiment, in order to adjust the preset angle between the second mounting plate 620 and the first mounting plate 610 so that the present application can meet more usage conditions, the preset angle between the second mounting plate 620 and the first mounting plate 610 can be 30°, 40°, 50°, 60°, etc. When the second mounting plate 620 and the first mounting plate 610 are hinged by bolts and nuts, the second mounting plate 620 and the first mounting plate 610 are positioned by means of a clamping force. When it is necessary to adjust the angle between the second mounting plate 620 and the first mounting plate 610, it is necessary to loosen the nut. At this time, the second mounting plate 620 and the first mounting plate 610 are not constrained by the clamping force. At this time, the angle between the second mounting plate 620 and the first mounting plate 610 can be adjusted. When the angle is adjusted to a suitable angle, the nut is tightened to fix the position of the second mounting plate 620 under the action of the clamping force. Thus, the above structure can be used to achieve angle adjustment of the second mounting plate 620 at a relatively low cost, further reducing the production cost of the present application.

[0047] In one embodiment, reference Figure 3 , the second mounting plate 620 is hinged to the first mounting plate 610 through a rotating shaft 630; the rotating shaft 630 is rotatably matched with the first mounting plate 610, the rotating shaft 630 is key-connected to the second mounting plate 620, and a second driving motor 640 for driving the rotating shaft 630 to rotate is installed on the first mounting plate 610; in this embodiment, the second driving motor 640 is installed on the first mounting plate 610, and the output end of the second driving motor 640 is connected to the rotating shaft 630. When it is necessary to adjust the angle between the second mounting plate 620 and the first mounting plate 610, it is only necessary to drive the rotating shaft 630 to rotate a certain angle through the second driving motor 640. In this embodiment, an angle sensor can also be configured to confirm the angle of rotation of the rotating shaft 630 through the angle sensor. At the same time, the second driving motor 640 in this embodiment can also be connected to the control system so that the rotation angle of the second mounting plate 620 can be controlled by the control system.

[0048] In one embodiment, the smoke exhaust assembly 400 further includes a negative pressure fan, a conveying pipe and a dust collecting frame (not shown in the figure), the conveying pipe connects the negative pressure fan and the negative pressure cover 410, and the dust collecting frame is used to collect dust in the smoke; in this embodiment, the negative pressure fan is electrically connected to the laser generator 310, when the laser generator 310 is working, the negative pressure fan also works, when the laser generator 310 stops working, the negative pressure fan also stops working, so that the energy consumption of the present application can be reduced. At the same time, when the smoke exhaust assembly 400 adopts the above structure, the air in the negative pressure cover 410 is extracted outward by the negative pressure fan, so as to form a negative pressure in the negative pressure cover 410, when the laser generator 310 is etching the tank body 700, the smoke generated can pass through the negative pressure cover 410 into the conveying pipe and then into the dust collecting frame. In this embodiment, the conveying pipe is arranged through the dust collecting frame, so that the smoke generated by etching the tank body 700 can enter the dust collecting frame.

[0049] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
