Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a sterile adapter. 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 surgeries and endoscopes. 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. In order to ensure the sterile conditions of the operation, a sterile curtain 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 cannula can be called a cannula fastening module, and the part connecting the sterile curtain and the cannula fastening module is called a sterile adapter. The sterile adapter can be firmly combined with the cannula fastening module. After the sterile adapter of the sterile curtain is firmly clamped on the cannula fastening module, the cannula can be installed on the cannula fastening module equipped with the sterile adapter.

[0004] The cannula fastening module is docked with the cannula after docking with the sterile adapter. The fastening effect of the cannula fastening module on the cannula may be reduced due to the isolation effect of the sterile adapter.

[0005] To this end, the present application provides a sterile adapter to at least partially solve the problems in the prior art. Utility Model Content

However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0051] In order to thoroughly understand the embodiments of the present invention, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the special details familiar to those skilled in the art. It should be noted that the ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of a "second component", and the term "second component" itself does not imply the existence of a "first component". The terms "upper", "lower", "front", "back", "left", "right" and similar expressions used in the present invention are for illustrative purposes only and are not restrictive.

[0052] Reference Figure 1 The present application provides a surgical robot 100. The surgical robot includes a main control operation device 110 and an adjacent mechanical system 120. The main control operation device 110 and the adjacent mechanical system 120 are connected by communication. The main control operation device 110 can receive the doctor's operation instructions, and the adjacent mechanical system 120 receives the control instructions of the main control operation device and performs the surgical operation.

[0053] Reference Figure 2 and Figure 3 In the para-patient mechanical system 120, the surgical instrument 121 is usually configured to be removably mounted on a robotic arm 122. The cannula 10 is a guiding device for inserting the surgical instrument 21 into the patient's body. The cannula 10 is configured to be removably docked with the robotic arm 122. The robotic arm 122 is provided with a cannula adapter 20, and the cannula adapter 20 is a cannula fastening module. When the cannula 10 is installed on the cannula adapter 20, a sterile isolation device, namely a sterile adapter 30, is provided between the cannula 10 and the cannula adapter 20. When fixing the cannula 10 to the cannula adapter 20, it is necessary to first dock the sterile adapter 30 to the cannula adapter 20, and then dock the cannula 10 to the sterile adapter 30, thereby achieving the function of fixing the cannula adapter 20 to the cannula 10. Refer to Figure 3 In an embodiment of the present application, the sterile adapter 30 mainly includes a main body 31 and a receiving portion 32. The main body 31 is used to dock with the cannula adapter 20 and be fixed to the cannula adapter 20. The receiving portion is used to dock with the cannula and transmit the clamping force of the cannula adapter 20 on the cannula 10 through the receiving portion 32. The main body 32 is configured to be removably sleeved on the cannula adapter 20. The shape of the main body 31 can be adapted to the shape of the cannula adapter 20. The main body 31 and the cannula adapter 20 can be fixed by a snap-on manner, so that the main body is difficult to detach from the cannula adapter. The main body 31 defines the shape of the receiving port 311. The receiving port is an insertion port when the cannula is docked with the sterile adapter.

[0054] Reference Figure 3 , Figure 4 and Figure 5 The shape of the receiving portion 32 is a concave structure extending from the receiving port. The receiving portion 32 can roughly adapt to the shape of the insertion portion 11 of the sleeve 10. The receiving portion 32 includes an inner side 32a facing the sleeve and an outer side 32b facing the sleeve adapter. The inner side of the receiving portion 32 can be engaged with the insertion portion 11 of the sleeve 10, and the outer side of the receiving portion 32 can be matched with the clamping fixture 21 of the sleeve adapter 20. The receiving portion 32 isolates the insertion portion 11 of the sleeve 10 and the sleeve adapter 20.

[0055] Reference Figure 6 In the embodiment, the receiving portion 32 includes a first rigid region 321 extending from the receiving port to the recessed structure and a second rigid region 322 supplementing the gap between the first rigid region 321. The rigidity of the first rigid region 321 is greater than the rigidity of the second rigid region 322. The first rigid region 321 has a certain rigidity and strength, so that the first rigid region can guide the insertion of the sleeve, so that the sleeve can be inserted quickly.

[0056] The inner side of the first rigid region 321 includes a first snap-fitting structure 3211 . When the receiving portion 32 is engaged with the inserting portion 11 of the sleeve 10 , the first snap-fitting structure 3211 snaps into the inserting portion 11 and prevents the inserting portion 11 from withdrawing from the receiving portion.

[0057] The outer side of the first rigid region 321 cooperates with the clamping fixture 21 of the sleeve adapter 20 and receives the force applied by the clamping fixture 21, thereby enhancing the blocking effect of the first clamping structure 3211 on the outer side of the first rigid region 321 on the insertion portion 11 withdrawing from the receiving portion.

[0058] In some embodiments, the first clamping structure is a convex structure on the inner side of the first rigid region.

[0059] Reference Figure 7 , Fig. 9 and Fig.10 , are three different embodiments of the sterile adapter. In these embodiments, the first snap-fit ​​structure 3211 is a raised structure on the inner side of the first rigid area. The receiving portion 32, it can be understood that at least part of the first rigid area 321 of the insertion portion 11 of the guiding sleeve 10 can be a flat, curved or smoothly transitioned structure. The first snap-fit ​​structure 3211 is configured as a raised structure formed on the basis of these guiding structures. Correspondingly, the sleeve 10 can be provided with a groove that cooperates with the raised structure. When the receiving portion 32 is in a docking state with the sleeve 10, and the raised structure is just inserted into the groove of the sleeve, a snap-fit ​​relationship is formed.

[0060] In some embodiments, the first clamping structure 3211 is a recessed structure on the inner side of the first rigid region.

[0061] Reference Fig.10 and Fig.11 , are two different implementations of the sterile adapter. In these embodiments, the first snap-fit ​​structure is a recessed structure on the inner side of the first rigid region. As mentioned above, at least a portion of the first rigid region 321 into which the insertion portion of the guide sleeve of the receiving portion 32 is inserted may be a flat, curved or smoothly transitioned structure. In these embodiments, the first snap-fit ​​structure 3211 is configured as a recessed structure based on the structure into which the insertion portion 11 of the guide sleeve 10 is inserted. Accordingly, the sleeve may be provided with a raised structure that cooperates with the recessed structure, so that when the receiving portion and the sleeve are in a docked state, the recessed structure just accommodates the raised structure of the sleeve to form a snap-fit ​​relationship.

[0062] In some embodiments, the outer side of the first rigid region includes a matching structure that matches with the clamping fixture, wherein the clamping fixture can exert a force on the receiving portion to cause the receiving portion to contract toward the inside of the recessed structure.

[0063] Specifically, the matching structure is a convex structure on the outside of the first rigid region, or the matching structure is a planar structure on the outside of the first rigid region.

[0064] Continue to refer to Figure 7 , Fig. 9 and Fig.10 , the first clamping structure 3211 is a convex structure on the inner side of the first rigid region 321, and the matching structure 3212 is a convex structure on the outer side of the first rigid region 321. In the embodiment, the first clamping structure 3211 and the matching structure 3212 can be arranged correspondingly at the inner side and the outer side of the first rigid region 321, respectively. Figure 7 The first clamping structure 3211 and the matching structure 3212 can also be staggered at the inner and outer sides of the first rigid region 321, respectively. Fig. 9 and Fig.10 .

[0065] Reference Fig.12 and Fig.13 The first clamping structure 3211 is a convex structure on the inner side of the first rigid region 321, and the matching structure 3212 is a planar structure on the outer side of the second rigid region. The first rigid region 321 includes two symmetrical parts located on both sides of the concave structure of the receiving portion 32, and the outer sides of the two symmetrical parts can both be planar structures, which can be the matching structure 3212. In the embodiment, the two planar structures can be parallel to each other. Fig.12The two planar structures may also be inclined, and the inclined state is a state where the receiving opening 311 gradually shrinks toward the inside of the concave structure, as shown in FIG. Fig.13 .

[0066] In some embodiments, the sterile adapter 30 may include a deformation hinge 33, which can cause the first rigid region 321 located at the extended portion extending into the recessed structure and the second rigid region 322 to generate deflection deformation.

[0067] Reference Figure 7 to Figure 13 The first rigid region 321 extends from the edge of the receiving port toward the inside of the recessed structure, and the position of the first rigid region 321 close to or located at the edge of the receiving port 311 is the deformation hinge 33 .

[0068] Reference Figure 6 In some embodiments, the first rigid region 321 surrounding the receiving port 311 includes a plurality of discontinuous portions. That is, the first rigid region 321 extending from the receiving port 311 is not a whole, but includes a plurality of portions, with gaps or spaces between the plurality of portions.

[0069] Further, refer to Figures 4 to 13 The main body 31 of the sterile adapter and the first rigid region 321 of the receiving portion 32 may be integrally formed, that is, the portion of the main body 31 located at the edge of the receiving port and the first rigid region 321 are integrally formed, and the first rigid region 321 may be deflected and deformed relative to the position of the main body 31 of the sterile adapter 30 around the edge of the receiving port 311, so that the deformation hinge 33 is approximately located at the edge of the receiving port 311 or close to the edge of the receiving port.

[0070] When the insertion portion 11 of the cannula 10 is inserted into the receiving portion 32 of the sterile adapter 30, the first clamping structure 3211 will hinder the insertion of the cannula to a certain extent, especially, for example Figure 7 to Figure 10 as well as Fig.12 and Fig.13 In the embodiment, the first clamping structure 3211 is a convex structure, therefore, the first rigid region 321 has a certain deformation ability, and the part of the first rigid region 321 extending to the inside of the recessed structure can be appropriately expanded, so that the insertion portion 11 of the sleeve 10 can be smoothly inserted into the receiving portion 32 of the sterile adapter 30.

[0071] Specifically, the main body 31 of the sterile adapter 30 and the first rigid region 321 of the receiving portion 32 can be integrally formed, that is, the portion of the main body located at the edge of the receiving port 311 is integrally formed, and the corresponding portion of the main body located at the edge of the receiving port and the first rigid region are also integrally formed. Figures 7 to 13 .

[0072] In some embodiments, the main body 31 and the receiving part 32 of the sterile adapter 30 are arranged as a split structure, so that the first rigid region 321 is separated from the main body 31. Specifically, the main body 31 is provided with a hole, the shape of which is roughly the same as the shape of the receiving port, and the receiving part 32 is implemented as a separate recessed structure, and the edge contour of the receiving part 32 is defined as the receiving port. Further, the edge of the receiving part may protrude with a flange or a gasket. The receiving part can pass through the hole of the main body, and the edge of the receiving part and the edge of the hole of the main body are locked. The main body is fixed by a fastener of the cannula adapter alone, and the receiving part and the cannula are fixed by the clamping fixture of the cannula adapter together.

[0073] In some embodiments, continue to refer to Figure 6 In the receiving portion of the sterile adapter, the first rigid region surrounding the receiving port may include a plurality of discontinuous portions, such as portion 321a, portion 321b, portion 321c, and portion 321d. In other words, the first rigid region is composed of a plurality of distributed portions. The first rigid regions 321 of the plurality of portions extend from the receiving port to the interior of the recessed structure, and there is a space or gap between the first rigid regions 321 of two adjacent portions. The second rigid region 322 fills these gaps. Accordingly, a portion of the second rigid region 322 can also be regarded as extending from the receiving port to the interior of the recessed structure. And the second rigid region 322 is continuous as a whole, and the second rigid region makes up for the space between the first rigid regions 321, so that the receiving portion completely isolates the two sides of the receiving portion.
