Description

Technical Field

[0001] The utility model relates to the field of medical device structure design, in particular to an interface identification mechanical structure. Background Art

[0002] In the field of medical devices - high-frequency electrosurgical units, various plugs and interfaces are often used. At present, most of the related medical device products on the market do not have the interface insertion recognition function. In this way, after the plug is inserted, the device is unaware of it, and the user cannot judge the effectiveness of the plug insertion. In some medical device fields, safety and intuitiveness will be greatly reduced; and because there are many kinds of accessories used, there are often many jacks on the machine, which gives people a messy feeling and the user's learning cost is relatively high. Therefore, how to design a mechanical structure with an interface recognition function, which can intuitively judge the insertion status and has a simple appearance is particularly important. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing medical device interface cannot judge the interface insertion status and the medical device has too many interfaces and the appearance is messy.

[0004] The utility model adopts a combination of a mechanical structure and a travel switch to convert mechanical action signals into electrical signals, which can effectively identify the plugging and unplugging actions of the interface, and the user can intuitively judge the effectiveness of the plug insertion. The travel switch is mainly triggered by a special structure of the interface contact handle, and the mechanical structure is arranged inside the device, leaving only the contact handle at the edge of the interface, which can effectively solve the problem of multiple and messy interfaces.

[0005] The technical solutions adopted are:

[0006] A mechanical structure for interface identification, characterized in that: the structure includes an interface shell and an interface cover, the interface shell is provided with a plurality of interfaces for plugging in external medical devices, the interface cover is installed on the interface shell, a circuit board is also installed on the interface shell, the circuit board is fixed between the interface shell and the interface cover, the circuit board includes a laparoscope plug fixing spring piece, an electrosurgical pen contact spring piece and a double contact spring piece, the laparoscope plug fixing spring piece is arranged on the side of the circuit board opposite to the interface cover, the electrosurgical pen contact spring piece and the double contact spring piece are arranged on the side of the circuit board not opposite to the interface cover, and are respectively located on both sides of the laparoscope plug fixing spring piece, a travel switch is also provided on the circuit board, the travel switch is arranged behind the double contact spring piece at the bottom of the circuit board, and an interface touch handle is provided at the interface of the interface shell for triggering the travel switch.

[0007] The utility model realizes compatibility with different medical device plugs by cooperating with multiple spring pieces and multiple interfaces, thereby reducing the situation where there are too many interfaces and the appearance is messy on the medical device. At the same time, through the cooperation of the touch handle and the travel switch, the mechanical action signal is converted into an electrical signal, which can effectively identify the plugging and unplugging action of the interface, and the user can intuitively judge the effectiveness of the plug insertion.

[0008] In the field of medical equipment - high-frequency electrosurgical units, intuitive judgment is required because the voltage of high-frequency equipment is relatively large, which sometimes causes sparks and poses a safety hazard. By adding the interface recognition mechanical structure of the utility model, the power status of the "interface" can be identified. If the device of the recognition port is not triggered, the interface will have no electricity, and if it is triggered, it will be powered on.

[0009] In a further preferred embodiment of the technical solution of the utility model, the multiple interfaces are compatible with laparoscope plugs and electrosurgical pen plugs; they are used to reduce the number of interfaces while being compatible with different types of plugs.

[0010] As a further optimization of the technical solution of the utility model, the interface shell and the interface cover are both made of flame-retardant ABS plastic material, which has good flame-retardant properties and excellent processing properties.

[0011] In a further preferred embodiment of the technical solution of the utility model, the touch handle slides inside the interface housing via a slide rail, thereby triggering the travel switch.

[0012] In a further preferred embodiment of the technical solution of the utility model, the slide rail is arranged on the housing below the travel switch.

[0013] In a further preferred embodiment of the technical solution of the utility model, the contact handle is arranged at an interface close to the double contact springs, and is used to drive the contact handle to move and trigger the travel switch when an external plug is inserted.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model realizes compatibility with laparoscope plugs and electrosurgical pen plugs by cooperating with multiple springs and multiple interfaces, thus reducing the situation where there are too many interfaces on the medical device and the appearance is messy.

[0016] 2. The utility model converts mechanical action signals into electrical signals through the cooperation of the touch handle and the travel switch, which can effectively identify the plugging and unplugging actions of the interface, and the user can intuitively judge the effectiveness of the plug insertion.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-6 As well as specific implementation methods, the present invention is further described. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] like Figure 1-6 As shown, an interface identification mechanical structure of the present embodiment includes an interface shell 6, an interface cover 5 and a circuit board 3. The interface cover 5 is arranged on the interface shell 6, and the circuit board 3 is also arranged on the interface shell 6 and fixed between the interface cover 5 and the interface shell 6. The left and right ends of the interface cover 5 are provided with grooves for convenient screw fixing, and the two ends of the circuit board 3 are also provided with screw holes for convenient screw fixing. The interface cover 5 is fixed to the interface shell 6 by screws penetrating the circuit board 3, and the circuit board 3 is fixed at the same time.

[0026] In this embodiment, multiple spring clips are respectively provided on the circuit board 3, and the multiple spring clips are respectively a laparoscope plug fixing spring clip 1 for fixing the laparoscope plug 7, two electrosurgical pen contact spring clips 2 for fixing the electrosurgical pen, and a double contact spring clip 4 that can be used to fix the electrosurgical pen plug 8 and the laparoscope plug 7.

[0027] like Figure 1-3 As shown, two electrosurgical pen contact springs 2 are arranged on a side of the circuit board 3 that is not close to the interface cover 5 and close to the left side of the interface shell 6. The two electrosurgical pen contact springs 2 are fixed to the circuit board 3 by screws respectively.

[0028] like Figure 1-3As shown, the laparoscope plug fixing spring piece 1 is arranged on a side of the circuit board 3 close to the interface cover 5, close to the right side of the electrosurgical pen contact spring piece 2, and the laparoscope plug 7 is fixed on the circuit board 3 by welding.

[0029] like Figure 1-3 As shown, the double contact spring 4 is arranged on a side of the circuit board 3 that is not close to the interface cover 5 and close to the right side of the interface housing 6, and is fixed on the circuit board 3 by welding.

[0030] like Figure 1-3 As shown, the bottom surface of the interface housing 6 is provided with a plurality of interfaces for facilitating the insertion of external medical device plugs at positions relative to the two electrosurgical pen contact springs 2 and the laparoscope plug fixing springs 1.

[0031] like Figure 1-3 As shown, the relative position of the interface cover 5 and the laparoscope plug fixing spring piece 1 is in an outwardly convex arc shape, which is used to accommodate the laparoscope plug 7.

[0032] like Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, a contact handle 9 is provided near the interface of the double contact spring sheet 4 , and a hollow slide rail 11 is longitudinally provided behind the contact handle 9 . The hollow slide rail 11 cooperates with the contact handle 9 so that the contact handle 9 can slide along the hollow slide rail 11 .

[0033] like Figure 4 and Figure 5 As shown, in this embodiment, the touch handle 9 is divided into an upper, middle and lower structure, the upper part is the touch handle 9 head that triggers the travel switch 10, the middle part includes a cylinder and a slide rail, the cylinder is fixed to the top of the slide rail, and a groove is also opened in the middle of the slide rail. The slide rail is surrounded by raised sliders that slide with the hollow slide rail 11, and the lower part includes an L-shaped block, which is fixed to the side of the cylinder, and the end of the L-shaped block that does not contact the cylinder is set at the edge of the interface. When the device is inserted with a plug, the end of the L-shaped block that does not contact the cylinder partially extends out of the interface housing 6, thereby facilitating the movement of the touch handle 9 when the external medical device plug is inserted.

[0034] like Figure 6 As shown, the distance between the hollow slide rail 11 near the interface housing 6 and the interface housing 6 is slightly larger than the distance from the rectangular block groove to the rectangular block near the interface housing 6 , which is used to cooperate with the hollow slide rail 11 to limit the moving direction of the touch handle 9 .

[0035] In this embodiment, a space is provided on the interface of the interface housing 6 near the double contact springs 4 to facilitate the movement of the contact handle 9 , thereby facilitating the movement of the contact handle 9 inside the interface housing 6 .

[0036] like Figure 4 and Figure 5As shown, a travel switch 10 is also fixed to the side of the circuit board 3 not close to the interface cover 5 , and the contact handle 9 cooperates with the hollow slide rail 11 under the action of the external medical device plug, thereby triggering the travel switch 10 .

[0037] like Figure 4 and Figure 5 As shown, in this embodiment, the distance between the head of the touch handle 9 and the trigger point of the travel switch 10 is less than or the distance that the touch handle 9 extends out of the interface housing 6, so that when the touch handle 9 triggers the travel switch 10, the lowest end of the touch handle 9 is flush with the interface housing 6, thereby avoiding the situation where the travel switch 10 cannot be triggered when an external medical device is inserted.

[0038] like Figure 1 and Figure 4 As shown, this is a schematic diagram of the internal structures of the interface housing when the device is not inserted into an external medical device plug.

[0039] like Figure 2 As shown, after the laparoscope plug 7 is inserted into the device, the front end of the laparoscope plug 7 abuts against the laparoscope plug fixing spring piece 1, and the side of the laparoscope plug 7 abuts against the double contact spring piece 4. The laparoscope plug fixing spring piece 1 and the double contact spring piece 4 are used to fix the laparoscope plug 7 and conduct electricity to the laparoscope plug 7 at the same time.

[0040] like Figure 5 As shown, after the laparoscope plug 7 is inserted into the device, the protruding shell of the laparoscope plug 7 abuts against one end of the touch handle 9 at the interface. As the laparoscope plug 7 is continuously extended, the touch handle 9 moves on the hollow slide rail 11 until the front end of the laparoscope plug 7 abuts against the laparoscope plug fixing spring 1. At this time, the head of the touch handle 9 triggers the travel switch 10, and the external machine receives the signal that the laparoscope plug 7 is inserted.

[0041] like Figure 3 As shown, when the electric surgical pen plug 8 is inserted into the present device, the two plugs near the left end of the electric surgical pen plug 8 are respectively inserted into the electric surgical pen fixing spring pieces and abut against the electric surgical pen fixing spring pieces, and the one plug near the right end of the electric surgical pen plug 8 abuts against the double contact spring piece 4. The electric surgical pen fixing spring piece and the double contact spring piece 4 are used to fix the electric surgical pen plug 8 while making the electric surgical pen plug 8 conductive.

[0042] When the electrosurgical pen plug 8 is inserted into the device, the protruding part of the shell of the electrosurgical pen plug 8 abuts against the contact handle 9 at the interface. As the electrosurgical pen plug 8 is inserted, the contact handle 9 moves on the hollow slide rail 11 under the action of the movement of the electrosurgical pen plug 8, thereby triggering the travel switch 10, and the external machine receives the signal that the electrosurgical pen plug 8 is inserted.

[0043] A method of using an interface identification mechanical structure in the present embodiment is as follows: a staff member inserts an external medical device plug through an interface on an interface shell 6, at which time the spring sheet corresponding to the interface fixes the external medical device plug, and at the same time, the outer shell of the external medical device plug abuts against the contact handle 9, driving the contact handle 9 to move toward the inside of the interface shell 6, thereby triggering the travel switch 10 and making the external medical device plug conductive.

[0044] The parts not covered by the utility model are the same as the existing technologies or can be implemented by using the existing technologies.

[0045] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
