Description

Interface device

Technical Field

The utility model relates to a connecting device technical field generally. More specifically, the present invention relates to an interface device.

Background

Stereotactic electroencephalography (SEEG) is an invasive epilepsy diagnosis and treatment technology, no craniotomy is needed, and electrodes are implanted into the brain through the stereotactic technology to study the discharge condition in the brain of an epileptic patient, so that an epileptogenic region or an epileptogenic network is positioned to guide the resection scheme of an epilepsy surgical operation. SEEG not only is used for the location diagnosis of epileptic seizure, but also provides a new treatment method for epileptic surgical treatment, namely radio frequency thermal coagulation and destruction, which is difficult to realize by subdural electrodes. After the SEEG monitors and records the epileptic seizure, the radio frequency thermal coagulation generator is connected with the corresponding target electrode contact, and the thermal coagulation treatment can be implemented without anesthesia beside a bed. However, since the brain electrode needs to be implanted into the brain, how to stably transmit the brain electrical signal to the electroencephalograph is a hot research issue at present.

The conventional interface device usually adopts a direct-insertion connection (or a pin-and-socket connection) such as a DIN connector (or a pin-and-plug connector), which may cause the interface and the terminal to fall off when the interface device is subjected to an external force, thereby causing the signal connection to be interrupted. Particularly, if the interface device is used in a medical instrument, the accuracy of medical detection and the safety and stability of the operation are directly affected if the signal connection is interrupted due to the interface device.

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings. Fig. 1 is a schematic diagram illustrating an interface device according to an embodiment of the present invention. As shown in fig. 1, in one embodiment of the present invention, the interface device 100 may include: a first end portion 110 that may have a first interface surface 111 and may have a first protrusion 112 on one side of the first interface surface 111; and a second end portion 120 that may have a second interface surface 121 that is adapted to the shape of the first interface surface 111, and may have a second protrusion 122 on one side of the second interface surface 121, such that when the second interface surface 121 is connected to the first interface surface 111, the first protrusion 112 and the second protrusion 122 are located on two sides of the connection, respectively.

The shape of the first interface surface 111 and the second interface surface 121 may be adapted to include the same or similar shape and size so that the two can be mated. In some embodiments, one of the first interface surface 111 and the second interface surface 121 may be provided with a pin, and the other of the first interface surface and the second interface surface may be provided with a socket corresponding to the position and shape of the pin, so as to realize the plugging between the first interface surface 111 and the second interface surface 121. In other embodiments, the first interface surface 111 and the second interface surface 121 may be connected by magnetic attraction, for example, as long as signal transmission therebetween is achieved. Signal transmission across the interface device 130 may be achieved through the connection between the first interface surface 111 and the second interface surface 121.

In other embodiments, the shapes of the first interface surface 111 and the second interface surface 121 may not be limited to the rectangular shapes in the drawings, but may also be regular or irregular shapes such as square, diamond, trapezoid, and the like. Taking a rectangular shape as an example in the figure, the first protrusion 112 may be located on a short side of the first interface surface 111 (as shown in fig. 1), or may be located on a long side of the first interface surface 111 (not shown in the figure); the second protrusion 122 may be located on the long side of the second interface surface 121 (as shown in fig. 1) or on the short side of the second interface surface 121 (not shown in fig. 1). When the second interface surface 121 is connected to the first interface surface 111, the first protrusion 112 and the second protrusion 122 may be respectively located at two adjacent sides of the connection, or may be respectively located at two opposite sides of the connection.

In some application scenarios, one end of the interface device 100 may be used to connect with the electroencephalograph 110, and the other end thereof may be used to connect with an electroencephalograph for transmitting the electroencephalogram signals to the electroencephalograph. The brain electrode 110 may be a brain electrical sensor that may be implanted in the brain. In other embodiments, the other end of the interface device 100 may be used for direct or indirect connection with an electroencephalograph (e.g., a stereotactic electroencephalograph), for example, the other end of the interface device 100 may be connected to an electroencephalograph by connecting a plurality of ports, such that electroencephalographic signals recorded by the electroencephalograph may be transmitted to the electroencephalograph via the interface device 100.

In another embodiment of the present invention, the interface device may further include: a circuit board, which may be disposed, for example, within the second end portion 120, for transmission of signals via the first end portion 110 when the second interface surface 121 is connected with the first interface surface 111. For example, in some application scenarios, a PCB board may be disposed within the second end portion 120 such that when the second end portion 120 is used to connect brain electrodes, all contacts of the brain electrodes may be brought together to the PCB board to connect to a cable through the PCB board and via the first end portion 110, and transmit brain electrical signals through the cable to the electroencephalograph.

The interface device according to the embodiment of the present invention is exemplarily described above with reference to fig. 1, and it can be understood that, according to the interface device of the present invention, a structure for side connection can be formed between the first end portion and the second end portion, so that the connection between the first end portion and the second end portion is tighter, and by providing the first convex portion and the second convex portion, more acting forces can be borne at the first convex portion and the second convex portion, so as to reduce the degree of stress on the first interface surface and the second interface surface, so that the first end portion and the second end portion are not easily detached when being subjected to the external force. Especially, compared with the interface device without the first convex part and the second convex part or only one of the first convex part and the second convex part, the connection structure between the first interface surface and the second interface surface can be effectively protected by the first convex part and the second convex part, for example, when the first convex part and the second convex part are connected in the form of a contact pin and a jack, the contact pin can be effectively prevented from being bent due to external force.

It is also understood that the structure of the interface device in the drawings is exemplary and not limiting, for example, the second protrusion 122 may not be limited to be located on the long side of the second interface surface 121 in the drawings, but may also be located on the short side of the second interface surface 121. As will be described in detail below in conjunction with fig. 2.

Fig. 2 is a schematic diagram illustrating an interface device according to another embodiment of the present invention. The interface shown in fig. 2 differs from the interface shown in fig. 1 in that the second protrusion 122 in fig. 2 may be located on the short side of the second interface surface 121. Further, in another embodiment of the present invention, the other side of the first interface surface 111 has a first end surface 211 opposite to the protruding direction of the first convex portion 112, and the first end surface 211 may be adapted to the inner side surface 222 of the second convex portion 122; and the other side of the second interface surface 121 has a second end surface 221 opposite to the protruding direction of the second protrusion 122, and the second end surface 221 may be fitted to the inner side surface 212 of the first protrusion 112.

In some embodiments, the other side of the first interface surface 111 may be opposite to the side of the first protrusion 112 on the first interface surface 111; the other side of the second interface surface 121 may be opposite to the side of the second protrusion 122 on the second interface surface 121. The inner side surface 222 of the second protrusion 122 is a surface of the second protrusion 122 facing the second interface surface 121. The inner surface 212 of the first protrusion 112 is a surface of the first protrusion 112 facing the first interface surface 111. In some embodiments, the first end face 211 fitting against the inner side face 222 of the second lobe 122 may include: the first end surface 211 is the same or similar in shape and size as the inner side surface 222 of the second protrusion 122. In other embodiments, the fitting of the second end surface 221 to the inner side surface 212 of the first protrusion 112 may include: second end surface 221 is the same or similar in shape and size as inner side surface 212 of first projection 112.

The interface device according to another embodiment of the present invention is exemplarily described above with reference to fig. 2, and it can be understood that, when the first interface surface 111 is connected to the second interface surface 121 by setting the first end surface of the first interface surface at the other side and the second end surface of the second interface surface at the other side, the interface device composed of the first end portion and the second end portion has a regular outer surface (for example, the outer surface is a cuboid structure, or a cube structure, etc.), so that the overall stress of the interface device is more uniform and the connection is more stable.

Further, according to the structural arrangement of the interface device shown in fig. 2, when the first interface surface and the second interface surface are both set to be rectangular, that is, the first end portion and the second end portion are both set to be L-shaped structures, and the first convex portion and the second convex portion are respectively located on two opposite sides of the joint of the first interface surface and the second interface surface, the interface device can have a fool-proof function, particularly, the first interface surface and the second interface surface can always keep the same contact direction, and the situation that a user attempts to connect one of the first interface surface and the second interface surface after turning the other interface surface can not occur, so that the occurrence of a reverse insertion situation can be fundamentally avoided, and the speed, the safety and the convenience of user operation can be improved.

For example, by using the manner that the first interface surface and the second interface surface are connected through the pins and the sockets, the plurality of pins may not be symmetrically arranged, and at this time, if there is no rectangular first interface surface and second interface surface, or there is no first protrusion and/or second protrusion, because there is no correspondence in a unique direction between the first interface surface and the second interface surface, a situation that the pins are attempted to be connected in a reversed manner may occur, resulting in that the pins cannot be inserted into corresponding sockets, so that a user needs to adjust the direction of the interface surfaces to retry. Therefore, according to the structural arrangement of the interface device shown in fig. 2, this problem can be perfectly solved.

Fig. 3 is a schematic diagram illustrating an interface device including a first connection port and a second connection port according to an embodiment of the present invention. As shown in fig. 3, in yet another embodiment of the present invention, the first end portion 110 may also have a first connection port 310, which may be located on an outer side 311 of the first protrusion 112 relative to the first interface surface, which may be used for connection with, for example, an electroencephalograph in some scenarios, or may be used for connection with a cable; and the second end 120 also has a second connection port 320, which may be located on an outer side 321 of the second protrusion 122 relative to the second interface surface, which may be used in some scenarios to connect with, for example, a brain electrode 350 or the like.

In some embodiments, outer side 311 of first lobe 112 may be opposite an inner side of first lobe 112 (e.g., inner side 212 shown in fig. 2), i.e., the inner side of first lobe 112 is the side of first lobe 112 facing the first interface surface, and outer side 311 of first lobe 112 is the side of first lobe 112 facing away from the first interface surface. In other embodiments, the outer side 321 of the second protrusion 122 may be opposite to the inner side (e.g., the inner side 222 shown in fig. 2) of the second protrusion 122, i.e., the inner side of the second protrusion 122 is a side of the second protrusion 122 facing the second interface surface, and the outer side 321 of the second protrusion 122 is a side of the second protrusion 122 facing away from the second interface surface.

As shown in fig. 3, when the first and second protrusions 112, 122 are located on opposite sides of the junction of the first and second interface surfaces, the first and second connection ports 310, 320 may be oriented on opposite sides (i.e., 180 °). In other embodiments, when the first protrusion 112 and the second protrusion 122 are located on adjacent sides of the junction of the first interface surface and the second interface surface (e.g., the interface device shown in fig. 1), the first connection port 310 and the second connection port 320 may be oriented in perpendicular directions (i.e., at 90 °).

It should be noted that, due to the arrangement of the first protruding portion 112 and the second protruding portion 122, when the first connection port 310 and the second connection port 320 are respectively arranged on the outer side surfaces of the first protruding portion 112 and the second protruding portion 122, the first protruding portion 112 and the second protruding portion 122 can bear an acting force which may be applied externally, which is beneficial to improving the bearing capacity of the interface device and effectively avoiding the sliding between the first interface surface and the second interface surface, thereby being beneficial to improving the connection stability between the first interface surface and the second interface surface.

As further shown in fig. 3, in some embodiments, first anti-skid bumps 330 may be disposed on an outer surface of first end portion 110; and/or the second end 120 may have a second non-slip bump 340 disposed on an outer surface thereof. The first anti-slip bump 330 and/or the second anti-slip bump 340 are disposed to facilitate the insertion and extraction operation between the first end portion 110 and the second end portion 120. In some embodiments, the first anti-skid protrusions 330 may be disposed on one or more outer surfaces of the first end portion 110; and/or second cleats 340 may be disposed on one or more outer surfaces of second end 120.

The outer surface of the first end portion 110 may include a surface of the interface device formed by connecting the first end portion 110 and the second end portion 120, where the first end portion 110 is exposed, such as a surface where the first anti-slip bump 330 is located in the drawing, and such as a back surface of the first end portion 110, which is not shown in the drawing. The outer surface of the second end 120 may include a surface of the interface device formed by connecting the first end 110 and the second end 120, where the second end 120 is exposed, such as a surface where the second anti-slip bump 340 is located in the drawing, and such as a back surface of the second end 120, which is not shown in the drawing.

For example, in an embodiment of the present invention, the first interface surface and the second interface surface may be connected by plugging. This will be described below in conjunction with fig. 4 and 5.

In some embodiments, the shape and size of the first plug section 510 and the second plug section 410 may be adapted. In other embodiments, the number of pins 511 in the first plugging region 510 may be set to one or more. The slots 411 that correspond one-to-one with the pins 511 may include slots 411 whose number, location, shape, depth, etc. may correspond to the pins 511. Further, the shapes of the first plugging region 510 and the second plugging region 410 may not be limited to the rectangular shapes in the drawings, and may be set to other shapes as needed.

In some embodiments, the pin 511 may be configured to protrude from the first interface surface 111 and the socket 411 may be configured to be recessed within the second interface surface 121. In other embodiments, the first plug section 510 may be recessed within the first interface surface 111; and the second plugging region 410 may protrude on the second interface surface 121, and the protruding height of the second plugging region 410 may be equal to the recessed depth of the first plugging region 510. According to the arrangement, the insertion between the pin 511 and the slot 411 can be firmer, and the first interface surface 111 and the second interface surface 121 can be in close contact with each other, so that the safety and the stability of the connection of the internal circuit can be ensured.

As further shown, for example, in fig. 5, at least one guide groove may be provided at an edge of the first plugging region 510, and guide blocks (not shown) corresponding to the guide grooves one to one may be provided at respective edges of the second plugging region 410, such that each guide block can be inserted into a corresponding one of the guide grooves.

In some embodiments, the guide groove 520 may be provided in a square, circular, trapezoidal, etc. shape, and the guide block may be provided in the same shape as the guide groove 520. In other embodiments, when a plurality of guide grooves 520 are provided, they may be uniformly spaced at the edge of the first plugging region 510, or may be symmetrically arranged at the edge of the first plugging region 510. The guide grooves and the corresponding guide blocks are arranged to facilitate the positioning and alignment of the first plugging area and the second plugging area, so that the insertion of the contact pins into the slots is facilitated.

It is to be understood that the illustration in fig. 5 is exemplary and not restrictive, for example, the guide groove 520 may not be limited to the edge of the first plugging region 510, and may be provided at the edge of the second plugging region 410 as needed. For example, the pins may not be limited to be disposed in the first plugging region 510, the slots may not be limited to be disposed in the second plugging region 410, and the pins may be disposed in the second plugging region 410 and the slots may be disposed in the first plugging region 510 as needed.

The top surface 530 of the first protrusion may be a top end surface of the first protrusion with respect to a protruding direction of the first interface surface. The top surface 420 of the second projection may be a top end surface of the second projection with respect to a projection direction of the second interface surface. According to the arrangement, the acting force from the outside of the first connecting port and the second connecting port is more concentrated on the first convex part and the second convex part and faces the direction in which the first interface surface and the second interface surface are connected with each other, so that the first interface surface and the second interface surface are more tightly connected, and the sliding between the first interface surface and the second interface surface can be fundamentally avoided.
