[0046] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0047] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0048] Please refer to Figure 1-Figure 3 , Figure 1 An exploded schematic diagram of a surgical device 100 provided in an embodiment of the present invention; Figure 2 An exploded schematic diagram of another surgical device 100 provided by an embodiment of the present invention; Figure 3 An exploded schematic diagram of another surgical device 100 provided in an embodiment of the present invention.

[0049] The present invention provides a surgical system (not shown), which includes a robotic arm and a surgical device 100. The robotic arm is detachably connected to the surgical device 100, so that the surgical device 100 is controlled by the robotic arm.

[0050] The surgical device 100 will be described in detail below:

[0051] In this embodiment, the surgical device 100 includes a quick connector 110, a power tool 120, and a plurality of surgical tools 130; the quick connector 110 includes a first plug 111 and a second plug 112, the first plug 111 and the second plug 112 are plugged together; the power tool 120 is connected to the first plug 111, and the power tool 120 is used to drive the surgical tool 130; any one of the plurality of surgical tools is connected to the second plug. It can be understood that the surgical device 100 can realize the rapid installation or removal of the power tool 120 and the surgical tool 130 by setting the quick connector 110.

[0052] It should be noted that, in this embodiment, the number of the second plug 112 is one, and the second plug 112 can be connected to any surgical tool 130. On this basis, combined with the plug-in cooperation of the second plug 112 and the first plug 111, any one of the multiple surgical tools 130 can be quickly installed or removed from the power tool 120, thereby realizing rapid switching of different surgical tools 130. Thus, by rapidly switching different surgical tools 130 to adapt to different surgeries, and the operation method of switching the surgical tools 130 is simple, the doctor's operation time is reduced and the surgical efficiency is improved.

[0053] In other embodiments, there are multiple second plugs 112, and the first plug 111 is plugged into any one of the multiple second plugs 112; each surgical tool 130 is integrally formed with a second plug 112. Thus, through the quick plug-in switching between the first plug 111 and the multiple second plugs 112, the switching of multiple surgical tools is realized, thereby adapting to different surgeries, reducing the doctor's operation time, and improving surgical efficiency.

[0054] Preferably, in this embodiment, the first plug 111 is a female plug; the second plug 112 is a male plug. It is understandable that when the male plug and the female plug are plugged together, the male plug needs to be inserted into the female plug for connection; in addition, the second plug 112 in this embodiment is connected to the surgical tool 130. When the surgical tool 130 and the second plug 112 are used, the surgical tool 130 and the second plug 112 need to be disinfected and sterilized; among them, the male plug is more convenient to sterilize than the female plug.

[0055] In other embodiments, the first plug 111 may also be a male plug, and the second plug 112 may also be a female plug.

[0056] For further information, please refer to Figure 1-Figure 10 , Figure 4 A cross-sectional view of a surgical device 100 provided in an embodiment of the present invention; Figure 5 for Figure 4 A partial enlarged view of the middle A; Figure 6A cross-sectional view of a power tool 120 provided in an embodiment of the present invention; Figure 7 A cross-sectional view of a first plug 111 according to an embodiment of the present invention; Figure 8 for Figure 7 A magnified view of the structure at B in the middle; Fig. 9 A schematic diagram of the structure of a drill chuck 131 and a second plug 112 provided in an embodiment of the present invention; Fig.10 A cross-sectional view of a drill chuck 131 and a second plug 112 provided in an embodiment of the present invention.

[0057] The first plug 111 includes a first plug body 1111, and the first plug body 1111 is provided with a first plug-in chamber 1114 and a through hole 1115, and the first plug-in chamber 1114 is connected to the outside through the through hole 1115. It can be understood that the through hole 1115 is a through hole. The first plug 111 also includes a locking sleeve 1112 and a movable member 1113, and the locking sleeve 1112 can be movably sleeved on the first plug body 1111, and has a first position for locking and a second position for unlocking, and can be switched between the first position and the second position.

[0058] The movable member 1113 is movably disposed in the through hole 1115. When the locking sleeve 1112 is located at the first position, the locking sleeve 1112 abuts against the movable member 1113, so that the movable member 1113 moves toward the direction of the first plug-in chamber 1114 driven by the locking sleeve 1112. When the locking sleeve 1112 is located at the second position, the locking sleeve 1112 is spaced from the movable member 1113, so that the movable member 1113 is released, and the movable member 1113 can move toward the first plug-in chamber 1114 or move away from the first plug-in chamber 1114 in the through hole 1115.

[0059] It should be noted that when the first plug 111 and the second plug 112 are not plugged in, if the locking sleeve 1112 is located at the first position, the movable member 1113 will block the insertion of the second plug 112, so that the second plug 112 cannot be plugged in with the first plug 111. When the second plug 112 has been inserted into the first plug 111, if the locking sleeve 1112 is located at the first position, the movable member 1113 abuts against the second plug 112 and the locking sleeve 1112, thereby blocking the movement of the second plug 112, so that the second plug 112 and the first plug 111 cannot be disassembled.

[0060] It can be understood that when the locking sleeve 1112 is located at the first position, the second plug 112 and the first plug 111 are locked, that is, the surgical tool 130 is locked. When the locking sleeve 1112 is located at the second position, the second plug 112 and the first plug 111 can move relative to each other, that is, the surgical tool 130 is unlocked. Therefore, the surgical device 100 can lock or unlock the surgical tool 130 by adjusting the locking sleeve 1112.

[0061] In short, when the surgical tool 130 needs to be installed, the locking sleeve 1112 is adjusted to the second position, and then the second plug 112 can be inserted into the first accommodating chamber 1315. After the male plug is plugged into the first plug 111, the locking sleeve 1112 is adjusted to the first position to lock the surgical tool 130 to prevent the surgical tool 130 from being disengaged. Similarly, when the surgical tool 130 needs to be disassembled, the locking sleeve 1112 is adjusted to the second position so that the second plug 112 can be taken out.

[0062] It should be noted that if other surgical devices 100 need to be reinstalled, other surgical tools 130 can be directly installed after the previous surgical tool 130 is taken out.

[0063] It is understandable that the doctor can quickly install or remove the surgical tool 130 by adjusting the position of the locking sleeve 1112, thereby realizing a quick switch between different surgical tools 130. Thus, the surgical device 100 can be applied to different surgeries, and can reduce the doctor's operation time and improve efficiency.

[0064] According to the above structure settings, please refer to Figure 1-Figure 10 The second plug 112 includes a second plug body 1121 , and an annular groove 1122 is provided on the outer wall of the second plug body 1121 ; when the locking sleeve 1112 is located at the first position, the movable member 1113 is clamped in the annular groove 1122 .

[0065] Specifically, in the process of the second plug 112 entering the first plug-in chamber 1114, when the annular groove 1122 is opposite to the through hole 1115, the locking sleeve 1112 is adjusted to move from the second position to the first position, so that the movable part 1113 moves toward the first plug-in chamber 1114 and moves into the annular groove 1122, so that the movable part 1113 abuts against the locking sleeve 1112 and the annular groove 1122, thereby preventing the movable part 1113 from moving along the axial direction of the through hole 1115 and the axial direction of the first plug-in chamber 1114, thereby fixing the surgical tool 130 and the power tool 120 to prevent the surgical tool 130 from detaching from the power tool 120.

[0066] During the process of disassembling the surgical tool 130, the locking sleeve 1112 is adjusted to the second position, driving the second plug 112 to leave the first insertion chamber 1114, thereby driving the movable member 1113 to move away from the first insertion chamber 1114, so that the movable member 1113 is separated from the annular groove 1122. Subsequently, other surgical tools 130 can be reinstalled to perform different surgeries.

[0067] Furthermore, the first plug 111 further includes a spring 1117, please refer to Figure 1-Figure 10 The spring 1117 is sleeved on the first plug body 1111 ; the spring 1117 acts on the locking sleeve 1112 to make the locking sleeve 1112 have a tendency to move from the second position to the first position.

[0068] Specifically, when the second plug body 1121 enters the first plug-in chamber 1114, the movable member 1113 abuts against the outer wall of the second plug 112, and the movable member 1113 moves away from the first plug-in chamber 1114 under the actuation of the second plug 112, and drives the locking sleeve 1112 to move from the first position to the second position. When the locking sleeve 1112 moves from the first position to the second position, the spring 1117 is compressed. When the annular groove 1122 approaches the through hole 1115, the holding force of the movable member 1113 from the second plug body 1121 is reduced, resulting in the release of the spring 1117, and the locking sleeve 1112 moves from the second position to the first position under the elastic action, thereby driving the movable member 1113 to move toward the first plug-in chamber 1114, so that the movable member 1113 is accommodated in the annular groove 1122 and abuts against the annular groove 1122, thereby fixing the surgical tool 130.

[0069] In this embodiment, according to the above content, please refer to Figure 1-Figure 10 , the protrusion 1119 is connected to the inner wall of the collar portion 1118; the collar portion 1118 is movably sleeved on the first plug body 1111; when the locking sleeve 1112 is located at the first position, the protrusion 1119 abuts against the movable member 1113; the protrusion 1119 actuates the movable member 1113 to move toward the first plug-in chamber 1114. It can be understood that in this embodiment, the protrusion 1119 abuts against the movable member 1113 and actuates the movable member 1113 to move toward the first plug-in chamber 1114. When the locking sleeve 1112 is located at the second position, the protrusion 1119 moves in a direction away from the through hole 1115, and the first plug body 1111 and the collar portion 1118 are spaced apart, so that the movable member 1113 can move away from the first plug-in chamber 1114.

[0070] Further, in this embodiment, please refer to Figure 1-Figure 10The movable member 1113 includes a plurality of balls 1116 circumferentially arranged around the axis of the first plug body 1111 . There are a plurality of through holes 1115 , and each ball 1116 can be movably disposed in one through hole 1115 .

[0071] Specifically, when the second plug body 1121 is inserted into the first plug cavity 1114 , the ball 1116 abuts against the outer wall of the second plug body 1121 , so that the ball 1116 rolls relative to the second plug body 1121 , thereby reducing friction.

[0072] According to the above, the power tool 120 further includes a tracer 124, which is connected to the support member and used to track the position of the surgical tool 130. The surgical device 100 can track the position of the surgical tool 130 by setting the tracer 124, thereby improving accuracy.

[0073] For further information, please refer to Figure 1-Figure 10 The power tool 120 includes a connecting body 121, a clamping shaft 122 and a motor 123. The motor 123 is located in the connecting body 121, and the clamping shaft 122 is located in the first plug-in chamber 1114. The clamping shaft 122 and the motor 123 are electrically connected, and the clamping shaft 122 is movably connected to the first plug body 1111. The second plug 112 also includes an input shaft 1123. The second plug body 1121 is provided with a second plug-in chamber 1124. The input shaft 1123 is located in the second plug-in chamber 1124. The clamping shaft 122 is provided with a clamping groove 1221. When the second plug 112 and the first plug 111 are plugged and matched, the input shaft 1123 is clamped with the clamping groove 1221.

[0074] Specifically, the clamping shaft 122 can rotate under the drive of the motor 123. Since the clamping shaft 122 is connected to the input shaft 1123, the power can be transmitted to the input shaft 1123, driving the input shaft 1123 to rotate. In addition, by providing the clamping groove 1221, the input shaft 1123 is clamped and matched with the clamping groove 1221, thereby improving the plugging stability of the second plug 112 and the first plug 111.

[0075] According to the above structural setting, each surgical tool 130 includes a main body, an output shaft and a tool. The main body is provided with a accommodating cavity, which is connected to the second plug-in cavity 1124; the output shaft is located in the accommodating cavity, and the two ends of the output shaft are respectively movably connected to the input shaft 1123 and the tool.

[0076] Specifically, the input shaft 1123 transmits power to the output shaft, and transmits the power to the tool through the output shaft, so that the tool rotates, and then the power of the motor 123 is transmitted to the tool through the sequential connection of the motor 123, the clamping shaft 122, the input shaft 1123 and the output shaft.

[0077] It should be noted that, because different surgical tools 130 are adapted for different types of surgeries, the tools used are different, and the power output by the output shaft is also different.

[0078] This embodiment lists several different surgical tools 130, namely, a drill chuck 131, a swing chuck 132, and an acetabular chuck 133. It should be noted that, in addition to the three surgical tools described in this embodiment, this embodiment may also include surgical tools for various surgeries such as a reciprocating saw, a ring saw, a planer, and a Kirschner wire.

[0079] The drill chuck 131, the swing chuck 132 and the acetabular record chuck 133 are all connected to a second plug 112, so that the drill chuck 131, the swing chuck 132 and the acetabular record chuck 133 can be switched by plugging different second plugs 112 with the first plug 111 in the power tool 120 to adapt to different orthopedic surgeries.

[0080] The following will take the drill chuck 131 as an example for detailed description:

[0081] Please refer to Figure 1-Figure 10 The drill chuck 131 includes a drill body 1311 , a drill tool 1312 , a drill output shaft 1313 and a plurality of reduction planetary gear sets 1314 ; the drill body 1311 is provided with a first accommodating chamber 1315 , and the first accommodating chamber 1315 is communicated with the second plug-in chamber 1124 .

[0082] The drill output shaft 1313 and the multiple sets of reduction planetary gear sets 1314 are both located in the first accommodation chamber 1315. The drill output shaft 1313 and the input shaft 1123 are connected through the multiple sets of reduction planetary gear sets 1314.

[0083] It can be understood that the drill grinding chuck 131 uses multiple sets of reduction planetary gear sets 1314 to make the rotation speed of the output shaft lower than the rotation speed of the input shaft 1123 , thereby reducing the rotation speed of the drill grinding tool 1312 .

[0084] The bur chuck 131 is further provided with a liquid infusion tube 1316 , which is welded to the bur body 1311 and connected to the first accommodating chamber 1315 for conveying physiological saline.

[0085] The following will take the swing clamp 132 as an example for detailed description:

[0086] Please refer to Figure 1-Figure 12 , Fig.11 A schematic diagram of the structure of the swing clamp 132 and the second plug 112 provided in an embodiment of the present invention; Fig.12A cross-sectional view of a swing clamp 132 and a second plug 112 provided in an embodiment of the present invention.

[0087] The swing chuck 132 also includes a swing body 1321, a knife seat 1322, a swing knife 1323, a camshaft 1324 and a shift fork 1325; the two ends of the swing body 1321 are respectively connected to the second plug 112 and the knife seat 1322. The swing body 1321 is provided with a second accommodating chamber 1326, and the second accommodating chamber 1326 is communicated with the second plug-in chamber 1124. The camshaft 1324 and the shift fork 1325 are both located in the second accommodating chamber 1326, and the shift fork 1325 is connected to the input shaft 1123 through the camshaft 1324, so that the shift fork 1325 can rotate eccentrically under the action of the camshaft 1324.

[0088] It should be noted that the shift fork 1325 in the swing chuck 132 is the output shaft mentioned above, and the swing chuck 132 drives the swing tool 1323 to swing through the shift fork 1325 .

[0089] The following will be described in detail by taking the acetabulum chuck 133 as an example:
