DETAILED DESCRIPTION

[0021] The technical content, structural features, purposes achieved and effects of the application will be described below in combination with the drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, rather than all the embodiments. In the following description, for the purpose of explanation, a number of specific details are set forth in order to provide a thorough understanding of various exemplary embodiments or implementations of the application. However, various exemplary embodiments can also be practiced without these specific details or with one or more equivalent arrangements. In addition, various exemplary embodiments can be different, but not necessarily mutually exclusive. For example, the specific shape, structure and characteristics of an exemplary embodiment can be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0022] Furthermore, spatially relative terms, such as "beneath", "below", "lower", "above", "upper", "on", "over", "higher", "side" (as in "sidewall") and the like, can be used herein for ease of description to describe one element's or feature's relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientations depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The devices can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0023] In the present application, the term "third component" means a component or device that is independent of the carding mechanism and can be carded and unlocked with the carding mechanism, including but not limited to the sterile isolation plate, instrument box and power box involved in the present application.

[0024] In the present application, unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, "connection" can be fixed connection, can also be detachable connection, or integral; can be directly connected, or indirectly connected through an intermediate medium.

[0025] Figure 1 A first embodiment provided by the present application is shown, which is a carding mechanism 100, including a base plate 1 and a pair of left and right oppositely arranged carding assemblies 2, and the pair of carding assemblies 2 are both fixedly connected to the upper end surface of the base plate 1.

[0026] The carding assembly 2 includes a moving piece 21 capable of moving back and forth along the left-right direction, a guide rail 22 extending along the left-right direction, a pair of carding pieces 23 respectively located at the front and rear of the carding assembly 2, and a pair of elastic pieces 24 respectively abutting against the pair of carding pieces 23. The guide rail 22 is fixedly connected to the upper end surface of the base plate 1, and the moving piece 21 includes a pressing portion 211, a guide portion 212 and a crossbar portion 213 which are integrally connected. The pressing portion 211 extends along the up-down direction and part of the outer wall of the pressing portion 211 extends outward to form a force receiving wall 214, and the force receiving wall 214 is used for externally applying an external force. The guide portion 212 extends along the left-right direction and is movably connected to the guide rail 22, and the crossbar portion 213 extends along the front-rear direction and simultaneously abuts against the pair of carding pieces 23. The carding piece 23 has a carding position (see Figure 5 ) capable of carding the third component and an unlocking position (see Figure 4 ) capable of allowing the third component to be separated, and is configured to be capable of moving back and forth between the carding position and the unlocking position.

[0027] In combination Figures 2-3 The substrate 1 is provided with a plurality of through-slots 11, a plurality of pairs of clamping seats 12 and a plurality of elastic bases 13, all of which are in the same number as the clamping members 23. The through-slots 11 are formed on the substrate 1, and each pair of clamping seats 12 is arranged on the front and rear sides of the corresponding through-slot 11. The clamping member 23 has an upper end 231, a lower end 232 and a rotating shaft 233 between the upper end 231 and the lower end 232. The clamping member 23 passes through the corresponding through-slot 11 and forms a rotatable shaft hole connection with the corresponding clamping seat 12 through the rotating shaft 233. The lower end 232 of the clamping member 23 is configured in a hook shape to clamp the corresponding third component. The elastic base 13 is located on the inner side of the corresponding clamping member 23, and the elastic member 24 is abutted to the elastic base 13 and the upper end 231 of the clamping member 23 through its two ends respectively and provides an outward force to the clamping member 23. The clamping member 23 is abutted to the horizontal rod part 213 through its upper end 231 under the action of the elastic member 24. In this embodiment, the elastic member 24 is a spring, and the elastic base 13 is integrally connected with the substrate 1.

[0028] In combination Figures 4-5 The working principle of the clamping mechanism 100 is described as follows: when an external force is applied to the stressed wall 214 towards the inner side of the clamping mechanism 100, the moving member 21 moves inwardly and compresses a pair of elastic members 24. In this process, the lower end 232 of the clamping member 23 moves outwardly until it reaches the unlocking position and is separated from the third component 10. After the external force is removed, the moving member 21 moves outwardly under the action of the pair of elastic members 24, and the clamping assembly 2 moves from the unlocking position to the clamping position and clamps the third component 10.

[0029] Figures 6-7 A second embodiment of the clamping mechanism 100' provided by the present application is shown, which is different from the clamping mechanism 100 in that the elastic member 24' of the clamping mechanism 100' is an elastic plate in a reverse U-shaped structure. Each elastic member 24' and the corresponding clamping member 23 are arranged as an integral member, and the side surface of each elastic member 24' away from the corresponding clamping member 23 is abutted to the corresponding elastic base 13. The elastic member 24' produces corresponding deformation when under pressure to provide an action force to the clamping member 23 to keep it in the clamping position.

[0030] Figures 8-9The third embodiment of the present application is shown in the figure, which is a clamping mechanism 100". The clamping mechanism 100" is different from the clamping mechanism 100 described above in that the elastic member 24" of the clamping mechanism 100" is a torsion spring and the clamping member 23" is provided with a hollow portion 234, the elastic member 24" is located in the hollow portion and abuts against the base plate 1 and the clamping member 23" through the two ends thereof respectively, so as to provide a force to the clamping member 23" towards the clamping position. In this embodiment, the function of the elastic base 13 is to limit the moving range of the corresponding clamping member 23".

[0031] Figure 10 The fourth embodiment of the present application is shown in the figure, which is an instrument box 300 capable of being clamped on the corresponding first sterile isolation plate 34 and comprising a first clamping mechanism 32, an instrument upper shell 31 located on the upper side of the first clamping mechanism 32 and an instrument transmission device (not shown in the figure) located in the instrument upper shell 31. The first clamping mechanism 32 can adopt the clamping mechanism 100, the clamping mechanism 100' or the clamping mechanism 100" provided by the present application, and the components of the first clamping mechanism 32 will not be described here.

[0032] In combination Figure 11 The instrument upper shell 31 is provided with pressing grooves 311 respectively matched with a pair of first pressing portions 321, the first stress wall 324 on the first pressing portion 321 extends towards the pressing groove 311 and is flush with the outer side wall surface of the instrument upper shell 31. The instrument upper shell 31 is a box-like structure with an open lower part and is fixedly connected to the upper end surface of the mounting seat 320, and the instrument upper shell 31 and the mounting seat 320 together define an instrument cavity 312. The instrument transmission device is located in the instrument cavity 312 and is arranged on the mounting seat 320, and the mounting seat 320 is further provided with a first power hole 3201 and an execution hole 3202, the instrument transmission device is drivingly connected with the power equipment (such as the power box 43 described below) outside through the first power hole 3201 and is drivingly connected with the corresponding actuator 33 (see below) through the first execution hole 3202.

[0033] The first sterile isolation plate 34 is provided with first clamping grooves 341 respectively matched with the first clamping members 323, the inner side of the first clamping groove 341 is provided with an inner groove structure (not shown in the figure) matched with the lower end portion 3232 of the corresponding first clamping member 323, the first clamping member 323 is configured to engage with the inner groove structure when located at the first clamping position and to be separated from the inner groove structure when located at the first unlocking position, so as to clamp and unlock the first sterile isolation plate 34.

[0034] Figure 12An application scenario of the instrument box 300 is shown, and the instrument box 300 is mounted with an execution device 33 for surgery. The execution device 33 includes an execution end 332 controlled by an instrument transmission device and an execution shaft 331 extending between the instrument transmission device and the execution end 332. The execution end 332 is formed by various surgical instruments (such as clamps, graspers, scissors, staplers, cauterizing tools, linear cutters, or needle holders, etc.), and the instrument transmission device can control the execution end 332 to act to perform surgical operations. The execution shaft 331 is used to realize the transmission connection between the control end and the execution end 332.

[0035] Figures 13-14 A fifth embodiment provided by the present application is shown, which is a sterile isolation plate assembly 400 including a second clamping mechanism 42 and a second sterile isolation plate 41 located on the upper side of the second clamping mechanism 42.

[0036] The second clamping mechanism 42 is different from the clamping mechanism 100 in that the second clamping member 425 of the second clamping mechanism 42 is connected with the corresponding second clamping seat 427 through the shaft hole of the upper end of the second clamping member 425, and the second base plate 420 of the second clamping mechanism 42 cancels the elastic base.

[0037] In combination Figure 15 The second sterile isolation plate 41 is provided with a pair of pressing grooves 411 respectively matched with a pair of second pressing portions (not shown in the figure), and the pair of pressing grooves 411 can be inserted into the corresponding second pressing portions and expose the second stress wall 424, and the second stress wall 424 is configured such that the outer surface thereof is flush with the outer surface of the corresponding position of the second sterile isolation plate 41. Part of the bottom wall of the second sterile isolation plate 41 extends downward and forms an inner side wall (not shown in the figure), and the inner side wall abuts against the side end of each second elastic member 426 away from the corresponding second clamping member 425, so that the second elastic member 426 can provide an action force to the corresponding second clamping member 425 towards the second clamping position. The second sterile isolation plate 41 in this example is fixedly connected with the second base plate 420. In other embodiments, a plurality of clamping grooves can be formed on the second sterile isolation plate, so that other devices (such as the instrument box 300 described above) with clamping mechanisms can be clamped with the second sterile isolation plate 41 through the clamping mechanisms of the devices themselves.

[0038] Figures 15-16An application scenario of the sterile isolation plate assembly 400 is shown, the sterile isolation plate assembly 400 is clamped on the power box 43 and located on the upper side of the power box 43. The power box 43 includes a top cover 431 located on the upper part, a power box body 432 located on the lower part, and a power cavity 435 defined by the top cover 431 and the power box body 432. The top cover 431 is fixedly connected to the power box body 432 and is provided with a plurality of power box clamping grooves 434 each capable of clamping the second clamping mechanism 42, and the power cavity 435 is capable of accommodating corresponding power equipment (including a battery, a motor, a transmission mechanism, etc., not shown in the figure). The sterile isolation plate assembly 400 is provided with a second power hole 44 penetrating through the sterile isolation plate assembly 400, and the top cover 431 of the power box 43 is provided with a third power hole 433 corresponding to the second power hole 44. In actual application, a transmission device corresponding to the second power hole 44 can be arranged in the sterile isolation plate assembly 400, and when the sterile isolation plate assembly 400 is clamped on the power box 43, the power equipment in the power box 43 transmits power outward through the third power hole 433, the second power hole 44 and the corresponding transmission device. In other application scenarios, the sterile isolation plate assembly 400 can also be clamped on an instrument box without a clamping mechanism. Such an instrument box includes a mounting seat provided with a plurality of clamping grooves, and when the sterile isolation plate assembly 400 is clamped on such an instrument box, the second sterile isolation plate 41 is located on the lower side of such an instrument box, and the second clamping mechanism 42 is clamped on the mounting seat of such an instrument box.

[0039] Figure 17 An application scenario of the instrument box 300 and the sterile isolation plate 400 is shown. The sterile isolation plate assembly 400 is clamped on the power box 43 and fixed on the corresponding mechanical arm 500, and the mechanical arm 500 can drive the sterile isolation plate assembly 400 and the power box 43 to move up and down synchronously. The instrument box 300 is clamped on the second sterile isolation plate 41 (in this example, the second sterile isolation plate 41 is provided with a plurality of clamping grooves) on the sterile isolation plate assembly 400 through the first clamping mechanism 32 of the instrument box 300. The four first clamping pieces 323 provided by the first clamping mechanism 32 can firmly clamp the second sterile isolation plate 41, preventing the instrument box 300 from shaking or even being uncoupled from the second sterile isolation plate 41. Similarly, the four second clamping pieces 425 of the sterile isolation plate assembly 400 can firmly clamp the top cover 431 of the power box 43, preventing the power box 43 from shaking or even being uncoupled from the second sterile isolation plate 41. The power equipment in the instrument box 43 provides power to the instrument transmission device in the instrument cavity 312 through the third power hole 433, the second power hole 44, the first power hole 3201 and the necessary transmission device. The instrument transmission device controls the actuator 33 to act by using the power. In other embodiments, the first clamping mechanism can provide more than four clamping pieces, and it can be understood that the more clamping pieces it provides, the more firmly it clamps on the corresponding sterile isolation plate.

[0040] In actual operation, the instrument box 300 mounted with different surgical tools needs to be replaced frequently according to the needs of the operation, and the second sterile isolation plate 41 is used to realize the connection with other surgical instruments (such as the mechanical arm 500 and the power box 43 in the figure) and prevent bacterial contamination between them, so as to ensure that the operation is carried out in a sterile environment.

Any equivalent changes or modifications made in accordance with the spirit of the present application shall be covered within the protection scope of the present application.
