Description

Technical Field

[0001] The utility model relates to the field of medical devices, and in particular to a connector and a surgical device. Background Art

[0002] In robot-assisted surgical operations, an actuator carrying a surgical tool is connected to the end of a robot arm. The robot arm can move autonomously or under the push of a doctor to move the surgical tool to a target position. During the operation, the end effector is rigidly connected to the end arm of the robot arm, and this connection needs to be stable and reliable. On the one hand, the stable and reliable rigid connection between the end effector and the robot arm ensures that the robot arm can move or position the surgical tool more precisely to the target position. On the other hand, based on the reliable and stable rigid connection, when the surgical tool cuts hard bone tissue, the connection between the end effector and the robot arm is not easily loosened due to vibration, which to a certain extent ensures the cutting accuracy of the surgical tool.

[0039] The connectors in the prior art are not conducive to aseptic isolation, resulting in contamination of the cutting site of the human body during the operation.

[0040] Based on this, the present utility model provides a surgical device, which includes a surgical instrument, a first cable, a robotic arm, a second cable, and a connector 100. The surgical instrument is connected to the first cable, the robotic arm is connected to the second cable, the connector 100 is connected to the surgical instrument and the robotic arm, and is electrically connected to the first cable and the second cable.

[0041] The connector 100 will be described in detail below:

[0042] Please refer to Figures 1-3 , Figure 1 which is an exploded schematic view of the connector 100 provided by an embodiment of the present utility model from a first perspective; Figure 2 which is a structural schematic view of the connector 100 provided by an embodiment of the present utility model from a second perspective; Figure 3 is Figure 2 the sectional view taken along line A-A in

[0043] The connector 100 includes a male plug 110, a male insert core 120, a female plug 130, and a female insert core 140; the male plug 110 is used to connect to the surgical instrument; the male insert core 120 is installed in the male plug 110, and the male insert core 120 is used to electrically connect to the first cable; the female plug 130 is used to connect to the robotic arm; the female insert core 140 is installed in the female plug 130, and the female insert core 140 is used to electrically connect to the second cable; wherein, the male plug 110 and the female plug 130 are in plug-in fit, so that the male insert core 120 and the female insert core 140 are electrically connected.

[0044] Specifically, the male plug 110 and the female plug 130 are respectively provided with a first installation cavity and a second installation cavity. The male plug core 120 is installed in the first installation cavity, and the female plug core 140 is installed in the second installation cavity. Among them, since the male plug 110 is connected to the surgical instrument and the female plug 130 is connected to the robotic arm, the first cable and the second cable respectively connected to the surgical instrument and the robotic arm need to be electrically connected through the connector 100. The first cable is passed through the first installation cavity and electrically connected to the male plug core 120, and the second cable is passed through the second installation cavity and electrically connected to the female plug core 140. Thus, by using the connection between the male plug core 120 and the female plug core 140, the first cable and the second cable are electrically connected.

[0045] It should be noted that in this embodiment, the second cable is connected to the robotic arm. In other embodiments, the second cable can also be connected to other medical controllers. It can be understood that the cable includes a power cable, a signal cable, etc. The robotic arm or other medical controllers can transmit signals to the surgical instrument through the signal cable to control the surgical instrument.

[0046] In this embodiment, please refer to Figure 1 , on one side where the male plug 110 and the female plug 130 are connected, there are a plurality of protrusions and grooves. When the male plug 110 is connected to the female plug 130, it is necessary to rotate to engage the protrusions with the corresponding grooves, so that the male plug 110 and the female plug 130 are connected together. At this time, the male plug core 120 and the female plug core 140 are also electrically connected.

[0047] The working principle of the connector 100 in the surgical device provided in this embodiment is as follows:

[0048] The connector 100 electrically connects the first cable to the male plug core 120 located in the male plug 110 and the second cable to the female plug core 140 located in the female plug 130. During the surgical process, when it is necessary to use the robotic arm to control the surgical instrument, the male plug core 120 is connected to the female plug core 140, so that the first cable and the second cable are electrically connected, and further the surgical instrument and the robotic arm are connected. After the surgery is completed, the male plug core 120 is disassembled from the female plug core 140, resulting in the disconnection of the first cable and the second cable, and further the disconnection of the surgical instrument and the robotic arm.

[0049] Since the male insert core 120 and the female insert core 140 are respectively located inside the male plug 110 and the female plug 130, that is, the male insert core 120 is located in the first installation cavity and the female insert core 140 is located in the second installation cavity. Thus, the first cable needs to pass through the first installation cavity and be connected to the male insert core 120, and the second cable needs to pass through the second installation cavity and be connected to the female insert core 140. That is, the first cable and the second cable are respectively located inside the male plug 110 and the female plug 130. This can prevent bacteria and the like from entering the surgical instrument due to the cables being placed outside, which is conducive to forming a sterile environment and avoiding contamination of the cutting site of the human body during the operation. Moreover, by connecting the first cable and the second cable inside the connector 100, it is also possible to prevent the cables from hindering the operation of the robotic arm, affecting the force control mode and load matching of the robotic arm.

[0050] Further, please refer to Figure 4 , Figure 4 which is a schematic structural diagram of the male insert core 120 provided by an embodiment of the present invention. The male insert core 120 includes a male insert core body 121 and contact pins 122. The contact pins 122 are connected to one side of the male insert core body 121 and are used for electrical connection with the female insert core 140. It should be noted that the contact pins 122 are of a compressible structure, and during the connection process between the contact pins 122 and the female insert core 140, the length of the contact pins 122 gradually decreases.

[0051] The connector 100 uses the contact pins 122 for electrical connection with the female insert core 140, enabling the contact pins 122 to be electrically connected to the second cable. In this embodiment, multiple contact pins 122 are provided to improve the connection stability, so that the robotic arm can better transmit signals to the surgical instrument.

[0052] According to the above settings, please refer to Figure 5 , Figure 5 which is a schematic structural diagram of the female insert core 140 provided by an embodiment of the present invention. The female insert core 140 includes a female insert core body 141. A jack 142 is provided on one side of the female insert core body 141, and the jack 142 is in plug-in fit with the contact pins 122. It should be noted that in this embodiment, the male insert core body 121 is connected with multiple contact pins 122, and the female insert core body 141 in this embodiment is provided with multiple jacks 142, and each contact pin 122 can be inserted into the corresponding jack 142.

[0053] Specifically, when the contact pin 122 is inserted into the socket 142, as the contact pin 122 abuts the bottom of the socket 142, the contact pin 122 is compressed, and the bottom of the contact pin 122 always abuts the bottom of the socket 142 to ensure a tight connection between the two. If the contact pin 122 fails to directly insert into the socket 142, the contact pin 122 will first abut the side wall of the socket 142 and be compressed due to the pressure. As the plug rotates, the position of the contact pin 122 will gradually change with the plug. During the rotation process, when the contact pin 122 is aligned with the socket 142, the contact pin 122 can automatically rebound and insert into the socket 142. Therefore, the user can hold the plug and perform blind insertion without having to observe the alignment of the contact pin 122 and the socket 142 before insertion, which improves work efficiency.

[0054] For further information, please refer to Figure 4 and Figure 5 The male plug 120 also includes a first connecting shaft 123, which is connected to the side of the female plug body 141 away from the contact pin 122 and is used to electrically connect to the first cable; the female plug 140 also includes a second connecting shaft 143, which is connected to the side of the female plug body 141 away from the socket 142 and is used to electrically connect to the second cable.

[0055] It should be noted that in this embodiment, the first cable and the second cable are respectively welded to the male ferrule 120 and the female ferrule 140. In this embodiment, a plurality of first connecting shafts 123 and second connecting shafts 143 are provided for welding to the first cable and the second cable, respectively, to prevent damage to the contact pins 122, the male ferrule body 121, or the female ferrule body 141 during the welding process.

[0056] Since both the male ferrule 120 and the female ferrule 140 are conductive structures, to prevent operators from getting electric shock during use, the connector 100 further includes an insulating sleeve 150 sleeved over the connection between the male ferrule 120 and the female ferrule 140 .

[0057] Furthermore, during use, the surgical instrument needs to be connected to different medical devices. To enable the operator to switch between the robotic arm and other medical devices, the second cable needs to be manually connected to different structures. At the same time, to prevent the operator from getting an electric shock, the connector 100 further includes an insulating pad 160 connected to the female plug 130 and the robotic arm. One side of the insulating pad 160 connected to the female plug 130 is provided with a first through hole 161, and the side wall of the insulating pad 160 is provided with a second through hole 162. The female plug 130, the first through hole 161, and the second through hole 162 are sequentially communicated. Specifically, the first mounting hole, the first through hole 161, and the second through hole 162 are sequentially communicated, so that the second cable electrically connected to the male plug core 120 is sequentially led out through the first mounting hole, the first through hole 161, and the second through hole 162, so that the second cable can be connected to the robotic arm or other medical devices, and it is avoided that bacteria and the like enter the surgical instrument due to the cable being placed outside, which is beneficial to forming a sterile environment, and it also avoids the cable from hindering the operation of the robotic arm and affecting the force control mode and load matching of the robotic arm.

[0058] Furthermore, please refer to Figure 2 , the connector 100 further includes a connecting member 170. Among them, the male plug 110 is detachably sleeved on the connecting member 170, and the connecting member 170 is provided with a third through hole 171, and the third through hole 171 is communicated with the male plug 110. And a part of the connecting member 170 extends out of the male plug 110 for connecting to the surgical instrument. Specifically, to improve the stability of the connection between the connector 100 and the surgical instrument, in this embodiment, a connecting member 170 is provided. The male plug 110 is sleeved on the connecting member 170, and the extending part of the connecting member 170 is connected to the surgical instrument, so that the male plug 110, the connecting member 170, and the surgical instrument are connected together, thereby improving the connection stability. A third through hole 171 is provided on the connecting member 170, so that the first cable can pass through the third through hole 171 and be connected to the male plug core 120 and the surgical instrument together, so as to avoid bacteria and the like from entering the surgical instrument due to the cable being placed outside, which is beneficial to forming a sterile environment and avoiding contamination of the cutting part of the human body during the operation.

[0059] In summary, the present embodiment provides a surgical device including a surgical instrument, a first cable, a robotic arm, a second cable, and the above-mentioned connector 100. The surgical instrument is connected to the first cable, and the robotic arm is connected to the second cable. The connector 100 includes a male plug 110, a male insert core 120, a female plug 130, and a female insert core 140. The male plug 110 is used to connect to the surgical instrument.
