Description

Technical Field

[0001] The present application relates to the field of medical equipment, and in particular to a cannula adapter and a surgical device. Background Art

[0002] In most robot-assisted surgeries, one or more surface incisions are first made on the patient's body to provide entry points for various surgical instruments and endoscopic instruments. The cannula is inserted into the patient's body cavity through the patient's surface incision, providing a channel for various surgical instruments and endoscopic instruments to enter the patient's body cavity for various surgical operations. The cannula is in direct contact with the wound surface and tissue of the human body and needs to be cleaned, disinfected and sterilized, but the robot's robotic arm end is usually designed to be non-cleanable, non-disinfectable and sterilized. In order to ensure sterile conditions during the operation, a sterile curtain adapter needs to be set between the robotic arm end and the cannula during the operation to isolate the non-sterile robotic arm end from the cannula used during the operation.

[0003] The module connecting the robot arm and the sleeve can be called a sleeve fastening module. The sleeve fastening module has hooks on both sides for clamping the sterile curtain adapter so that the sterile curtain adapter can be firmly combined with the sleeve fastening module. After the sterile curtain adapter is firmly clamped on the sleeve fastening module, the sleeve can be installed on the sleeve fastening module equipped with the sterile curtain adapter.

[0004] The hooks on both sides of the sleeve fastening module are movably connected to the two sides of the sleeve fastening module, and are respectively provided with a button fixed to the hook, and are also respectively provided with an elastic element to keep it in a position where the sterile curtain adapter can be clamped.

[0044] refer to Figures 1 to 6 The present application provides a surgical device 100. The surgical device 100 includes a cannula adapter 1 and a sterile adapter 2.

[0045] The cannula adapter 1 of the present application includes a shell 11 and a hook structure 12. A cavity 111 is provided inside the shell 11. Two first openings 112 are symmetrically provided in the shell 11. The cavity 111 is connected to the outside through the first opening 112. The hook structure 12 is pivotally connected to the shell 11 and includes a hook 121. The cannula adapter 1 includes two hook structures 12. The hooks 121 of the two hook structures 12 can pass through the two first openings 112 respectively. The sterile adapter 2 can cover at least part of the surface of the shell 11 of the cannula adapter 1, and two third openings 21 are symmetrically provided. When the sterile adapter 2 is connected to the cannula adapter 1, the two hooks 121 can respectively at least partially pass through the third opening 21, thereby achieving the connection and fixation of the sterile adapter 2 and the cannula adapter 1.

[0046] In the existing scheme, the operator needs to operate the two hook structures 12 simultaneously and separately so that the two hooks 121 can enter the cavity 111 from the third opening 21 to achieve the clamping fixation of the sterile adapter 2 and the cannula adapter 1. The operator's action needs to apply force to the two hooks or buttons simultaneously and accurately to unlock, otherwise the unlocking fails. In the process of removing the sterile adapter and the sterile curtain connected to the sterile adapter from the surgical robot, when the operator operates the unlocking of the sterile adapter 2 and the cannula adapter 1, at least two fingers need to apply force to the two hooks or buttons simultaneously and accurately to unlock the two hooks at the same time, otherwise only one side of the hook is unlocked, and the unlocking fails and needs to be unlocked again, resulting in repeated operations by the operator and lack of convenience. At the same time, during the unlocking process, the operator must not only unlock the sterile adapter and the cannula adapter, but also detach the sterile adapter from the cannula adapter at the same time, which requires specific operating steps to complete.

[0047] The sleeve adapter 1 provided in the present application also includes a connecting rod structure 13 and a reset member 14. The connecting rod structure 13 is arranged in the cavity 111 and connects the two hook structures 12 so that the two hook structures 12 are linked. The reset member 14 acts on the connecting rod structure 13. Among them, the hook structure 12 includes a clamping state and a loosening state: when the hook structure 12 is in the clamping state, the hooks 121 are exposed from the first opening 112 to the housing 11. When the hook structure 12 is in the loosening state, the hooks 121 enter the cavity 111 from the first opening 112, and the reset member 14 always provides a force that makes the hook structure 12 tend to the clamping state. When the hook structure 12 is in the clamping state, the two hooks 121 respectively at least partially pass through the third opening 21 and form a clamping connection with the sterile adapter 2. When the hook structure 12 is in the loosening state, the two hooks 121 are respectively detached from the sterile adapter 2.

[0048] The two hook structures 12 are linked by the connecting rod structure 13, so that the operator can switch between the engaged state and the released state of the two hook structures 12 by controlling the movement of one of the hook structures 12. Compared with the existing technical solutions, the cannula adapter 1 of the present application has low operation requirements for the operator, is simple and convenient to operate, and improves the ease of disassembly of the sterile adapter 2 and the cannula adapter 1.

[0049] In addition, compared with the technical solution in which the reset member 14 acts on the two hook structures 12 respectively, the connecting rod structure 13 of the sleeve adapter 1 of the present application can link the two hook structures 12, so the reset member 14 can achieve the reset of the two hook structures 12 only by acting on the connecting rod structure 13. In this way, the setting position of the reset member 14 can be adapted to the structure of the sleeve adapter, which does not affect the occupied space of other structures in the sleeve adapter, is also conducive to the miniaturization of the surgical device 100, and can also improve the economy and assemblability of the surgical device 100.

[0050] The operator can press the hook 121 toward the cavity 111 so that the hook structure 12 can switch from the engaged state to the released state. In some embodiments, the housing 11 includes a pressing port connected to the cavity 111. The hook structure 12 is provided with a pressing portion 122 exposed from the pressing port. The pressing portion 122 is connected to the hook 121. When the operator applies a force to the pressing portion, the pressing portion drives the hook to move toward the cavity 111, and the hook structure 12 switches from the engaged state to the released state. Figure 4 When the operator releases the pressing portion, due to the action of the reset member 14, the pressing portion 122 and the hook move toward the outside of the housing, and the hook structure 12 switches from the loose state to the hooked state, as shown in FIG. Figure 3 shown.

[0051] Since the hook 121 is usually small in size, it is inconvenient to operate. By providing a pressing portion 122, the operator can move the hook 121 by pressing the pressing portion 122, without directly manipulating the hook 121, which is conducive to improving the comfort of operation. In addition, since the connecting rod structure 13 of the sleeve adapter 1 of the present application can link the two hook structures 12, the sleeve adapter 1 has only one hook structure 12 and is provided with a pressing portion 122, which can also realize the switching of the two hook structures 12 between the engaged state and the released state, realizing "one-key disassembly" and "one-key connection".

[0052] Of course, the housing 11 of the cannula adapter 1 may also include two pressing ports, and the two hook structures 12 are both provided with pressing portions 122 exposed from the pressing ports. This embodiment enables the operator to select a more convenient pressing portion 122 to achieve the disassembly and connection of the cannula adapter 1 and the sterile adapter 2, further improving the ease of operation of the cannula adapter 1.

[0053] The pivotal position of the hook structure 12 and the housing 11 is Figure 3 In some embodiments, the distance between the pressing portion 122 and the pivot point 123 is smaller than the distance between the hook 121 and the pivot point 123. This arrangement is conducive to improving the compactness of the cannula adapter 1, thereby miniaturizing the cannula adapter 1 and making it easier for medical staff to operate it with one hand.

[0054] refer to Figures 3 to 5 In some embodiments, the two hook structures 12 are respectively a first hook 15 and a second hook 16. The connecting rod structure 13 includes a first connecting rod 131 and a second connecting rod 132. One end of the first connecting rod 131 is fixedly connected to the first hook 15 to drive the first hook 15 to pivot relative to the housing 11. One end of the second connecting rod 132 is pivotally connected to the first connecting rod 131 and the other end is hinged to the second hook 16 to drive the second hook 16 to pivot relative to the housing 11. When the first connecting rod 131 and the second connecting rod 132 are linked, the first hook 15 and the second hook 16 pivot in opposite directions.

[0055] The cannula adapter 1 is a relatively small structure, and the space inside the cavity 111 is limited. The connecting rod structure 13 of this embodiment can realize the linkage of the first hook 15 and the second hook 16 through the two connecting rods of the first connecting rod 131 and the second connecting rod 132, which effectively simplifies the clamping structure of the cannula adapter 1 and improves the space utilization of the cavity 111. In addition, since the first hook 15 and the second hook 16 only need to complete the pivoting movement, the minimum number of connecting rods can improve the accuracy of the movement of the first hook 15 and the second hook 16, thereby improving the success rate and simplicity of the switching of the hook structure 12 between the loose state and the clamping state.

[0056] In other embodiments, the connecting rod structure 13 can also realize the linkage between the first hook 15 and the second hook 16 by increasing the number of connecting rods, for example, increasing the number of connecting rods to three, four, etc., and the present application does not limit this.

[0057] Combined with reference Figure 6The first connecting rod 131 includes a first yielding portion 1311. The first yielding portion 1311 is arranged near the inner wall 113 of the sleeve adapter 1, and the first yielding portion 1311 is pivotally connected to the second connecting rod 132. The second connecting rod 132 includes a second yielding portion 1321. The second yielding portion 1321 is arranged near the inner wall 113 of the sleeve adapter 1, and the second yielding portion 1321 is pivotally connected to the first connecting rod 131. By arranging the first yielding portion 1311 and the second yielding portion 1321 near the inner wall 113, the connecting rod structure 13 can reserve an assembly position for the sterile adapter 2 or other structures inside the sleeve adapter in the cavity 111, avoid interference between the connecting rod structure 13 and other structures inside the sterile adapter 2 or the sleeve adapter, and do not need to design a yielding structure for other structures inside the sterile adapter 2 or the sleeve adapter, which effectively reduces the design cost and processing cost of the surgical device 100.

[0058] Of course, based on the space required by the sterile adapter 2 in the cavity 111 and the shape of the sterile adapter 2, the cannula adapter 1 may have only the first connecting rod 131 provided with the first paving portion 1311, or only the second connecting rod 132 provided with the second paving portion 1321, and the present application does not limit this.

[0059] like Figure 3 As shown, the reset member 14 is disposed in the cavity 111. One end of the reset member 14 is connected to the inner wall 113 of the cavity 111, and the other end is connected to the connecting rod structure 13. The reset member 14 applies force to the connecting rod structure 13 so that the hook structure 12 can switch from the loose state to the clamping state. Figure 3 and Figure 4 The reset member 14 is a tension spring. One end of the tension spring is connected to the inner wall 113 of the cavity 111, and the other end is connected to the connection point 133 of the first connecting rod 131 and the second connecting rod 132. Figure 3 In the illustrated embodiment, the hook structure 12 is in a snap-on state. Figure 4 In the embodiment shown, the hook structure 12 is in a released state. When the hook structure 12 switches from the locked state to the released state, the connection point 133 is Figure 3 In this embodiment, the tension spring has a tendency to retract, so that after the operator releases the hook structure 12, the reset member 14 can pull the connection point 133 downward, so that the hook structure 12 can switch to the engaged state. In this way, the operator does not need to manually reset the hook structure 12 to achieve the engaged state between the sterile adapter 2 and the cannula adapter 1, the operation is simple and convenient, and the disassembly and connection efficiency of the surgical device 100 is improved.

[0060] In other embodiments, the reset member 14 is in a compressed state and has a tendency to stretch. Figure 4In the illustrated embodiment, one end of the reset member 14 connected to the inner wall 113 may be disposed between the connection point 133 and the first hook 15. When the connection point 133 moves upward, that is, the hook structure 12 switches from the clamping state to the loose state, the connection point 133 further compresses the reset member 14. After the operator releases the grip, the reset member 14 extends, thereby pushing the connection point 133 to move downward, so that the hook structure 12 switches from the loose state to the clamping state.

[0061] like Figure 2 As shown, in some embodiments, the reset member 14 can also be configured as a torsion spring. One end of the torsion spring is connected to the inner wall 113 of the cavity 111, and the other end abuts the connecting rod structure 13. When the hook structure 12 switches to the loose state, the connecting rod structure 13 presses the reset member 14. When the operator releases the hook structure 12, the reset member 14 rebounds, thereby switching the hook structure 12 to the clamping state.

[0062] In some embodiments, the reset member may also be configured as a compression spring, which may act on any connecting rod or any hook to achieve the snap connection of the hook.

[0063] Figures 3 to 5 In the illustrated embodiment, one end of the reset member 14 is connected to the inner wall 113 of the cavity 111, and the other end is connected to the connection point 133, that is, it can be regarded as connected to the first connecting rod 131 and the second connecting rod 132. However, this should be regarded as exemplary and not restrictive. In other embodiments, the reset member 14 can also be connected to one of the first connecting rod 131 or the second connecting rod 132, and the present application does not limit this.

[0064] refer to Figure 5 , the hook structure 12 is pivotally connected to the housing 11 at the pivot point 123. In some implementations, the hook 121 includes a guide surface 1211. The guide surface 1211 is disposed on a side of the hook 121 away from the pivot point 123. And one end of the guide surface 1211 away from the pivot point 123 is close to the cavity 111. In other words, when the sterile adapter 2 is connected to the cannula adapter 1, the sterile adapter 2 first contacts the guide surface 1211. And in the process of the sterile adapter 2 being connected to the cannula adapter 1, the sterile adapter 2 can cooperate with the guide surface 1211 to move the hook 121 toward the direction of the cavity 111, so that the hook structure 12 is switched to a loose state.

[0065] By providing the guide surface 1211, when the operator connects the sterile adapter 2 to the cannula adapter 1, there is no need to manually operate the hook structure 12 to move the hook 121 toward the cavity 111. The operator only needs to press the sterile adapter 2 to the cannula adapter 1, and the hook 121 can switch from the clamping state to the loose state and then switch from the loose state to the clamping state under the joint action of the guide surface 1211 and the reset member 14, thereby achieving the connection between the sterile adapter 2 and the cannula adapter 1.

[0066] It is easy to understand that when the sterile adapter 2 is engaged with the cannula adapter 1, if the sharp corners of the edges contact the guide surface 1211, it is easy to cause damage to the guide surface 1211. Figure 4 As shown, in some embodiments, a side of the sterile adapter 2 facing the cannula adapter 1 is provided with an inclined surface 22. The inclination direction and slope of the inclined surface 22 are the same as those of the guide surface 1211. When the sterile adapter 2 moves toward the cannula adapter 1, the inclined surface 22 contacts the guide surface 1211. The inclined surface 22 has the same slope as the guide surface 1211, so the sterile adapter 2 and the cannula adapter 1 can form a surface-to-surface contact, thereby achieving a soft contact, thereby avoiding damage to the sterile adapter 2 and the cannula adapter 1, and extending the service life of the surgical device 100.

[0067] like Figure 1 and Figure 2 As shown, in some embodiments, the housing 11 includes a first housing member 114 and two symmetrically arranged second housing members 115. The two second housing members 115 are symmetrically located on the two outer surfaces of the first housing member 114 to enclose a cavity 111. Two first openings 112 are symmetrically opened in the two second housing members 115, respectively. The first housing member 114 is provided with a second opening (not shown) communicating with the cavity. The hook structure 12 is installed in the second opening. The pivot point 123 of the hook structure 12 is located at the second opening.

[0068] When assembling the sleeve adapter 1, the assembler can first assemble the hook structure 12 and the connecting rod structure 13 in the cavity 111 through the second opening, and then assemble the second housing member 115 at the second opening to close the cavity 111. This split structure is conducive to the assembly of the connecting rod structure 13 and the hook structure 12 and the subsequent disassembly and maintenance.

[0069] In the embodiment where the housing 11 includes a pressing opening communicating with the cavity, the pressing opening may be provided in the second housing member 115. Compared with the embodiment where the pressing opening is provided in the first housing member 114, the pressing opening in the second housing member 115 facilitates the assembly of the hook structure 12. The assembler only needs to close the second housing member 115 to the second opening to achieve the cooperation between the pressing opening and the pressing portion 122.

[0070] Based on the above embodiments, the present application further provides a surgical device (not shown). The surgical device includes a cannula, a robotic arm, and the surgical device 100 described in the above embodiments. The cannula is connected to a side of the sterile adapter 2 away from the cannula adapter 1. The robotic arm is connected to a side of the cannula adapter 1 away from the sterile adapter 2.

[0071] The surgical device 100 of the present application includes a cannula adapter 1. The two hook structures 12 of the cannula adapter 1 are linked by a connecting rod structure 13, so that the doctor operating the surgical device can achieve the connection or disassembly of the cannula adapter 1 and the sterile adapter 2 by only controlling the movement of one of the hook structures 12. It can be seen that the surgical device allows the doctor to operate with one finger and one hand, which is simple and convenient to operate, improves the ease of connection and disassembly of the sterile adapter 2 and the cannula adapter 1, and thus improves the doctor's operating efficiency and reliability during surgery or disinfection.

[0072] The specific embodiments described herein are merely examples of the spirit of the present application. A person skilled in the art of the present application may make various modifications, supplements, or replace the described specific embodiments with similar methods, but they will not deviate from the spirit of the present application or exceed the scope defined by the attached claims.

[0073] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above 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.
