[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] An isolation component for a module mounting base includes: a housing covering the module mounting base and separating the power-powered module mounting base from the non-powered surgical functional module; and a gear transmission structure in which gears are rotatably mounted on the housing to transmit power from the power source inside the module mounting base to the surgical functional module, thereby realizing power transmission. The gear transmission structure includes an internal gear and an external gear, which are separated by the isolation structure and coaxially connected by a transmission shaft.

[0033] The internal gear is rotatably mounted on the housing and directly meshes with the power gear or gear ring inside the module mounting base, or meshes with the power gear or gear ring inside the module mounting base through a first transmission gear. The external gear is rotatably mounted on the housing and directly meshes with the gear or gear ring of the surgical function module, or meshes with the gear or gear ring of the surgical function module through a second transmission gear. This internal and external gear design allows for convenient spatial layout of the gear transmission structure, and provides simple and reliable power transmission. It also allows for the lateral arrangement of the servo motor with the planetary reducer, improving structural compactness and reducing manufacturing costs.

[0034] The housing is also provided with an electrical signal transmission part for transmitting electrical signals. The electrical signal transmission part is a spring pin or conductive contact provided on the housing. The spring pin or conductive contact on the housing contacts the conductive contacts or spring pins of the module fixing seat and the surgical function module respectively, so as to realize the transmission of electrical signals between the module fixing seat and the surgical function module.

[0035] Alternatively, the housing may have a perforated section, through which the conductive contacts or spring pins of the surgical function module can contact the spring pins or conductive contacts of the module fixing seat, thereby enabling the transmission of electrical signals between the module fixing seat and the surgical function module.

[0036] The housing includes an isolation housing and an isolation base plate. The isolation housing can be fitted onto the module mounting base. The isolation base plate is rotatably or detachably closed and is mounted on the isolation housing and locked and fixed to the isolation housing, so that the isolation base plate and the isolation housing cover the module mounting base.

[0037] The gear transmission structure is provided at least one. When there is one gear transmission structure, the gear transmission structure transmits the power of the internal power source of the module fixing seat to the corresponding surgical function module. When there are two or more gear transmission structures, each gear transmission structure transmits the power of the internal power source of the module fixing seat to different surgical function modules or different gears or gear rings of the same surgical function module.

[0038] When the surgical function module consists of a rotary delivery mechanism and a port control mechanism, the rotary delivery mechanism has a gear ring on its rotating shaft, and the port control mechanism has a bifurcated valve. One end of the bifurcated valve is a catheter connector with a first gear, and the other end is a valve connector with a second gear. There are three gear transmission structures: a first gear transmission structure, a second gear transmission structure, and a third gear transmission structure. The second transmission gear in the first gear transmission structure meshes with the gear ring on the rotating shaft to drive the rotating shaft of the rotary delivery mechanism to rotate. The external gear in the second gear transmission structure meshes with the first gear to drive the catheter connector to rotate. The external gear in the third gear transmission structure meshes with the second gear to drive the valve connector to rotate, controlling the valve connector to open or close the channel.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, each module mounting base is fitted with an isolation housing 10270101, and the bottom of the isolation housing 10270101 is provided with an isolation base plate 1027010101 that can be rotated open or detachably opened. During installation, the isolation base plate 1027010101 is opened, the housing is fitted onto the module mounting base from top to bottom, and then the isolation base plate 1027010101 is closed and locked. This isolates the sterile environment of the module mounting base from the sterile environment during surgery (functional modules such as the second port control mechanism 10273 and the first rotary delivery mechanism 10272 are sterilized). The isolation housing 10270101 is provided with several gear transmission structures, which transmit power from the module mounting base to the sterile port control mechanism and / or rotary delivery mechanism. The structure includes an internal gear 1027010103 and an external gear 1027010102. The internal gear 1027010103 is disposed inside the isolation housing 10270101, and the external gear 1027010102 is disposed outside the isolation housing 10270101. The internal gear 1027010103 and the external gear 1027010102 are connected by a drive shaft. The drive motor 1027010104 in the module mounting base drives the internal gear 1027010103 to rotate through the drive gear 1027010105. The internal gear 1027010103 drives the external gear 1027010102 to rotate through the drive shaft. The external gear 1027010102 then provides power to the second port control mechanism 10273 and / or the first rotary delivery mechanism 10272. The isolation housing 10270101 is provided with a spring pin 1027010106, which is used to connect the first rotary delivery mechanism 10272 and the conductive contacts on the module fixing base, and to transmit the electrical signal between the two.

[0040] The design of internal and external gears makes it easy to realize the spatial layout of the gear transmission structure, and the power transmission is simple and reliable. This allows the servo motor 1027010104 with planetary reducer to be arranged laterally (the installation direction of the surgical function module is vertical), which improves the compactness of the structure and reduces manufacturing costs.

[0041] When the isolation base plate 1027010101 can be rotated and closed, one side of the isolation base plate 1027010101 is hinged to the bottom of the isolation housing 10270101, and a locking structure is provided between the other side of the isolation base plate 1027010101 and the isolation housing 10270101; the locking structure is one or a combination of a snap-fit ​​structure, a latch structure, or a threaded structure.

[0042] As an alternative, the spring pin 1027010106 may not be provided. At the position where the conductive contacts on the first rotary delivery mechanism 10272 and the module fixing seat are opposite, the isolation housing 10270101 may also have a hollow part, through which the conductive contacts on the first rotary delivery mechanism 10272 are connected to the conductive contacts on the module fixing seat.

[0043] Example 2

[0044] This embodiment refers to the working principle of embodiment 1, and the difference between it and embodiment 1 is that:

[0045] like Figures 3 to 6 The gear transmission structure further includes two second transmission gears 102702. The external gear 1027010102 meshes with the gear ring 10270203 on the rotating shaft 10270202 of the first rotary delivery mechanism 10272 through the second transmission gears 102702. The rotating shafts 10270202 of the two second transmission gears 102702 are arranged in parallel. The two second transmission gears 102702 mesh with the gear ring 10270203 on the rotating shaft 10270202 of the first rotary delivery mechanism 10272 at the same time. The two second transmission gears 102702 mesh with the external gear 1027010102 at the same time.

[0046] As an alternative, the gear transmission structure also includes two sets of internal gears and two sets of external gears, with their rotation axes arranged in parallel. The two sets of internal gears simultaneously mesh with the power gear or gear ring inside the module mounting base, and the two sets of external gears simultaneously mesh with the gear ring 10270203 on the rotation shaft 10270202 of the first rotary delivery mechanism 10272. The two sets of internal gears and the two sets of external gears are separated by the same isolation structure. In this case, there is no need to provide two second transmission gears 102702.

[0047] When the surgical function module consists of a first rotary delivery mechanism 10272 and a second port control mechanism 10273, the first rotary delivery mechanism 10272 has a gear ring 10270203 on its rotating shaft 10270202, and the second port control mechanism 10273 has a bifurcation valve. One end of the bifurcation valve is a catheter connector with a first gear 1027301, and the other end is a valve connector with a second gear 1027302. There are three gear transmission structures: a first gear transmission structure, a second gear transmission structure, and a third gear transmission structure. The second transmission gear 102702 in the first gear transmission structure meshes with the gear ring 10270203 on the rotating shaft 10270202 of the first rotary delivery mechanism 10272, and is used to drive the rotating shaft 10270202 of the first rotary delivery mechanism 10272 to rotate. The external gear 1027010102 in the second gear transmission structure meshes with the first gear 1027301, and is used to drive the conduit connector to rotate. The external gear 1027010102 in the third gear transmission structure meshes with the second gear 1027302, and is used to drive the valve connector to rotate, and control the valve connector to open or close the channel.

[0048] The isolation structure is a protective cover 102703 mounted on the housing. The protective cover 102703 has a first cavity, a second cavity, and a partition 102704. The first cavity and the second cavity are separated by the partition 102704. The external gear 1027010102 is rotatably mounted in the first cavity. One side of the first cavity has a first opening communicating with the outside of the housing. The external gear 1027010102 meshes with the gear ring 10270203 on the rotating shaft 10270202 of the second transmission gear or the first rotating delivery mechanism 10272 through the first opening. The internal gear 1027010103 is rotatably mounted in the second cavity. The second cavity has a second opening on one side that communicates with the interior of the housing. The internal gear 1027010103 meshes with the first transmission gear or the power gear or gear ring inside the module fixing seat through the second opening. The internal gear 1027010103 and the external gear 1027010102 are connected by a transmission shaft 102705, and the transmission shaft 102705 passes through the through hole of the partition 102704. A sealing ring 10270401 is provided on the outer side of the transmission shaft 102705 or at the through hole of the partition 102704. The sealing ring 10270401 achieves a sealing fit between the transmission shaft 102705 and the through hole of the partition 102704.

[0049] A zero-position switch is also provided near the second opening of the housing. This zero-position switch is one of a mechanical limit switch, a magnetic induction switch, or a photoelectric induction switch. The zero-position switch is used to confirm the zero-position rotation of the gear or gear ring of the surgical function module. Preferably, the zero-position switch is a magnetic induction switch mounted on the housing, with a magnet on the gear or gear ring of the surgical function module.

[0050] In the second and third gear transmission structures, a first transmission gear 10270201 is provided between the internal gear 1027010103 and the power gear 101 inside the module mounting base. The first transmission gear 10270201 is used to compensate for the excessive distance between the internal gear 1027010103 and the power gear 101 inside the module mounting base, and plays the role of transmission connection.
