In the following description, many specific details are set forth so that those skilled in the art can more fully understand and implement the present invention. However, it is obvious to those skilled in the art that the implementation of the present invention may not have some of these specific details.

In addition, in the following description, terms such as "first", "second", etc. are used to describe the elements of the present application, and these terms are only used to distinguish the elements, and are not intended to limit the nature, sequence, order or number of these elements.

[0033] Figure 1 A view showing a portion of a connecting device of the present invention. Figure 1 The first interface 10, the second interface 20 and the connection line 40 for connecting the first interface 10 and the second interface 20 are shown. The specific connection method of the first interface 10 and the second interface 20 will be described in detail below in conjunction with other drawings.

[0034] Figure 2 1 shows a view of the first interface of the connection device of the utility model. Figure 2 It can be seen that the first interface 10 includes a plurality of pins. When in use, the first interface 10 is connected to, for example, a computer terminal. To this end, the first interface 10 can adopt an RS232 interface. As an exemplary structure, the first interface 10 can include 9 pins, and the 9 pins are arranged in two rows, the first row is provided with 5 pins, and the second row is provided with 4 pins. For ease of description, the pins in the first row are numbered 1-5 in order from left to right, and the 4 pins in the second row are numbered 6-9 in order. In order to avoid confusion with the reference numerals, Figure 2 Arabic numerals with circles are used in the 9 pins. These 9 pins can be used for receiving line signal detection, receiving data, sending data, data terminal ready, ground line, data device ready, request to send, clear to send and ring prompt.

[0035] Figure 3 FIG. 2 shows a view of the second interface of the connection device of the present invention. The second interface 20 may include four connection parts, which are represented by A, B, C, and D respectively. Figures 1 to 3 In the connection device of the utility model, the first interface 10 and the second interface 20 are connected through the connecting line 40, and the specific connection method is: the connecting part A of the second interface 20 is connected to the receiving data pin of the first interface 10, and the connecting part B of the second interface 20 is connected to the sending data pin of the first interface 10, or the connecting part B of the second interface 20 is connected to the receiving data pin of the first interface 10, and the connecting part A of the second interface 20 is connected to the sending data pin of the first interface 10; the connecting part C of the second interface 20 is connected to the clear send pin of the first interface 10, and the connecting part D of the second interface 20 is connected to the request send pin of the first interface 10, or the connecting part D of the second interface 20 is connected to the clear send pin of the first interface 10, and the connecting part C of the second interface 20 is connected to the request send pin of the first interface 10.

[0036] Figure 4 FIG. 2 shows a circuit diagram of the third interface 30 of the connection device of the present invention. Figure 4It can be seen that the third interface 30 includes four wiring parts, namely the first wiring part L1, the second wiring part L2, the third wiring part L3 and the fourth wiring part L4. Among them, the first wiring part L1 and the second wiring part L2 are respectively connected to the two ends of the foot switch S, and the third wiring part L3 and the fourth wiring part L4 are directly connected through a wire. The foot switch is a normally open switch, which has a movable part and a fixed part. When a force is applied to the movable part, for example, by a foot, the movable part can contact the fixed part, thereby connecting the first circuit L1 and the second circuit L2. When the force applied to the movable part is eliminated, the movable part leaves the contact under the action of, for example, a reset member. Of course, the foot switch can adopt other forms of structures known in the prior art. The reset member can adopt a torsion spring or other forms of springs.

[0037] When the third interface 30 is connected to the second interface 20 correspondingly, the first line L1 and the second line L2 of the third interface 30 are respectively connected to the connection part C and the connection part D of the second interface 20, or the first line L1 and the second line L2 of the third interface 30 are respectively connected to the connection part D and the connection part C of the second interface 20, that is, it is sufficient to connect the two lines and the two connections, and this connection relationship is not uniquely corresponding. The third line L3 and the fourth line L4 of the third interface 30 are respectively connected to the connection part A and the connection part B of the second interface 20, or the third line L3 and the fourth line L4 of the third interface 30 are respectively connected to the connection part B and the connection part A of the second interface 20; similarly, it is sufficient to connect the two lines and the two connections, and this connection relationship is not uniquely corresponding.

[0038] The structure of the connection device of the utility model is described in detail above. The working process of the connection device of the utility model applied to medical equipment is described below.

[0039] When in use, after the third interface 30 and the second interface 20 are connected in the above-mentioned connection mode, and after the first interface 10 is connected to the computer end, since the third line L3 and the fourth line L4 of the third interface 30 are respectively connected to the connection part A and the connection part B of the second interface 20, and at the same time, the connection part A and the connection part B of the second interface 20 are respectively connected to the sending data pin and the receiving data pin of the first interface 10, and the third line L3 and the fourth line L4 are connected by a wire, thus forming a connected line from the sending data pin and the receiving data pin of the first interface 10. If a data is sent from the computer end at this time, the data can be returned from the sending data pin via the above-mentioned connected line to the receiving data pin and received via the receiving data pin, thereby indicating that the connection device has been connected.

[0040] On the other hand, after the third interface 30 and the second interface 20 are connected in the above-mentioned connection mode, and after the first interface 10 is connected to the computer end, since one end of the first line L1 and the second line L2 of the third interface 30 are respectively connected to the connection part C and the connection part D of the second interface 20, and at the same time, the connection part C and the connection part D of the second interface 20 are respectively connected to the request sending pin and the clear sending pin of the first interface 10, and the first line L1 and the second line L2 are respectively connected to the foot switch S between their respective other ends, when the foot switch S is turned on, the request sending pin and the clear sending pin of the first interface 10 are connected to form a connected circuit. For the clear sending pin, its state is low when it is open, and its state changes to high after it is short-circuited with the request sending pin. Therefore, when the foot switch S is stepped on and the clear sending pin is short-circuited with the request sending pin, the computer end can detect this state change, and then the preset function of the foot pedal can be triggered according to this state change, thereby realizing the monitoring of the foot switch.

[0041] As can be seen from the above, the utility model proposes a connection device, which utilizes the characteristics of clear-send and request-send in the pins of a commonly used serial communication interface such as RS232, and short-circuits the two ends of the foot switch with the clear-send and request-send pins respectively, and utilizes the characteristics that the clear-send state is low when open, and changes to high after short-circuiting with the request-send. Thus, the serial port end will send a status indication to the control end such as a computer according to the state change of the clear-send, and the control end can trigger the preset function of the foot after receiving the status bit. According to the preferred embodiment of the utility model, the status bit in the serial communication protocol is cleverly utilized to realize the monitoring of the foot switch.

[0042] Of course, the present invention can also use other types of interfaces besides RS232, as long as it contains two pins and can achieve state conversion after short-circuiting. In addition, the present invention can also be combined with corresponding functional design, so that the state changes after one of the pins is short-circuited. The complexity of this functional design is also lower than the complexity of requiring special circuit design for the foot switch, and the connection device of the present invention can also be used to monitor the function of the foot switch.

[0043] Furthermore, by designing another circuit to short-circuit the two pins for receiving data and sending data, it is possible to determine whether the serial port cable is connected or whether the cable is damaged. This only requires sending a data at the control end, and the determination result can be obtained by whether the data receiving pin receives the data.

[0044] Likewise, the above solution preferably utilizes an RS232 interface, but it is not necessary to rely on this type of interface, as long as the other lines form a closed loop to enable signal transmission and reception.

[0045] The connection device of the utility model can be applied to various medical devices that require a foot switch. For example, it can be used in a navigation system such as a navigation system for spinal treatment. The connection device is provided with an interface device corresponding to the first interface 10, so that the foot switch can be connected to the medical device to achieve the required function.

[0046] The structure of the connection device of the utility model has been described in detail above. Those skilled in the art know that many of the details described are merely exemplary and not restrictive. That is, it is sufficient to achieve its corresponding functions, and it is not necessary to adopt the specific shapes, structures and other features described above.

[0047] The present invention has been clearly and completely described with reference to the above exemplary embodiments. It should be understood by those skilled in the art that various other embodiments can be conceived by modifying the disclosed technical solutions without departing from the spirit and scope of the present invention. These embodiments should be understood to fall within the scope of the present invention determined based on the claims and any equivalent technical solutions thereof.
