Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a multifunctional ultrasonic scalpel connection device. Background Technology

[0002] An ultrasonic scalpel is a surgical instrument that uses high-frequency mechanical vibration to cut tissue and coagulate blood. The ultrasonic scalpel requires a compatible operating system to utilize a hybrid ultrasonic-electric energy source for propulsion. This involves obtaining ultrasonic signals (e.g., 55kHz) from a powered surgical device and high-frequency current signals (e.g., 470kHz) to drive an electrosurgical unit. Ultrasonic scalpels typically use a detachable connector with a plug and socket for connection to the electrosurgical unit; therefore, the stability of this connection directly affects the stability of the ultrasonic scalpel's operation.

[0003] On the other hand, ultrasonic scalpels require extremely high energy control to achieve surgical objectives. Therefore, depending on the intended use and surgical site, different ultrasonic scalpels are suited to different energy levels. Connecting an ultrasonic scalpel to an incorrect operating system can pose significant risks. Therefore, correctly connecting the scalpel to the appropriate operating system is crucial for its proper use. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multifunctional ultrasonic scalpel connection device.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A multifunctional ultrasonic scalpel connection device includes a socket and a plug. The proximal end of the socket has a socket into which the plug can be inserted. A locking rod assembly is built into the socket. The locking rod assembly includes a locking rod and a transmission connector. The locking rod is connected to the socket via the transmission connector. An arc-shaped limiting groove is provided on the shell wall of the socket. An L-shaped slot matching the arc-shaped limiting groove is provided on the shell wall of the plug. The rod portion slides vertically into the arc-shaped limiting groove, and its bottom end is slidably engaged in the L-shaped slot. The turning point forms the dead point of the locking rod. As the plug is inserted into the socket, the bottom end of the locking rod slides into the L-shaped slot from the beginning of the slot until it reaches the end of the slot, thus limiting the insertion between the plug and the socket. The socket is provided with an identification switch that is directly opposite the socket. The distance between the identification switch and the socket is adapted to the insertion length of the plug. The identification switch is triggered only when the plug is fully inserted into the socket, so as to realize the effective insertion between the plug and the socket.

[0007] Preferably, the first groove segment extends from the starting end of the L-shaped slot to its turning point, and the second groove segment extends from its turning point to its ending end. The extension direction of the first groove segment is consistent with the insertion direction of the plug, and the extension direction of the second groove segment is perpendicular to the insertion direction of the plug.

[0008] Preferably, in the initial state, the rod portion of the locking rod is located at the initial end of the arc-shaped limiting groove. As the plug is inserted into the socket, the bottom end of the locking rod slides from the starting end of the slot into the L-shaped slot. In the final state, the rod portion of the locking rod is located at the ending end of the arc-shaped limiting groove, and the bottom end of the locking rod is located at the ending end of the slot.

[0009] Preferably, the transmission connector includes a first link and a second link. The first link is pivotally connected to the socket via a first pivot shaft to form a first pivot connection point. One end of the second link is pivotally connected to the socket via a second pivot shaft to form a second pivot connection point. The other end of the first link and the other end of the second link are also pivotally connected to form a third pivot connection point. The locking rod is vertically inserted at the third pivot connection point. The line connecting the first pivot connection point and the second pivot connection point is parallel to the line connecting the starting end and the ending end of the L-shaped slot. The distance between the first pivot connection point and the second pivot connection point is less than the sum of the lengths of the first link and the second link, so that the turning point of the L-shaped slot forms the dead point position of the locking rod.

[0010] Preferably, the middle part of the locking rod is fixed in the second connecting rod, and the other end of the first connecting rod has a groove extending along its axial direction. A first spring is embedded in the groove, and the end of the first spring abuts against the locking rod and always exerts a thrust on the locking rod.

[0011] Preferably, a second spring is embedded in one end of the second connecting rod, and a second retaining ring is engaged on the end of the second rotating shaft near the first connecting rod. The second spring abuts against the inner wall of the second connecting rod.

[0012] Preferably, the end of the first rotating shaft is connected to the first connecting rod pivot via a first retaining ring.

[0013] Preferably, the plug has a set of pins built in, and the socket has a set of holes that match the pins.

[0014] Preferably, the socket has a set of limiting ribs protruding from its shell wall, the extension direction of the set of limiting ribs being consistent with the insertion direction of the plug, and the plug has a set of sliding grooves recessed on its shell wall that match the limiting ribs.

[0015] Preferably, the plug housing has a set of anti-slip ribs spaced apart on the top or bottom.

[0016] The beneficial effects of this utility model are mainly reflected in:

[0017] 1. A locking rod assembly is installed inside the socket, and an L-shaped slot is installed at the far end of the plug. The L-shaped structure of the slot creates a dead point at the bend. The locking rod engages with the L-shaped slot to restrict the plug and prevent it from coming out of the socket, ensuring the stability of the plug-socket connection. An identification switch is installed inside the socket to detect the insertion of the plug. The activation of the identification switch determines whether the plug is compatible with the socket. The locking rod assembly and identification switch provide a dual effective connection guarantee between the plug and the socket through mechanical mechanism and signal connection, ensuring an effective, reliable and stable plug-socket connection.

[0018] 2. A first spring is installed in the first link to always exert a thrust on the locking rod, ensuring that the locking rod is always located at the third pivot connection point. The elastic force of the first spring itself can reduce the hard contact between the locking rod and the third pivot connection point, reduce the wear on the locking rod during movement, and improve the smoothness of the locking rod's movement.

[0019] 3. An arc-shaped limiting groove is set on the socket housing to limit the movement direction of the locking rod while ensuring its smoothness to the greatest extent. An L-shaped slot is set on the plug housing to form a dead point position for the locking rod, thereby limiting the movement of the locking rod. Attached Figure Description

[0027] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0028] In the description of the solution, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for ease of description and simplification. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction closer to the operator is the proximal end, and the direction farther from the operator is the distal end.

[0029] like Figures 1 to 6As shown, this utility model discloses a multifunctional ultrasonic scalpel connection device, including a socket 1 and a plug 2. The proximal end of the socket 1 has a socket 102 into which the plug 2 can be inserted. The socket has a built-in locking rod assembly, which includes a locking rod 301 and a transmission connector. The locking rod 301 is connected to the socket 1 through the transmission connector. The shell wall of the socket 1 is provided with an arc-shaped limiting groove 101. The shell wall of the plug 2 is provided with an L-shaped slot 201 that matches the arc-shaped limiting groove 101. The rod of the locking rod 301 is vertically slidably inserted into the arc-shaped limiting groove 101, and its bottom end is slidably locked into the L-shaped slot 201. The bend 204 of the slot 201 forms the dead point of the locking rod 301. As the plug 2 is inserted into the socket 102, the bottom end of the locking rod 301 slides into the slot from the starting end 202 of the L-shaped slot 201 until it moves to the ending end 203 of the slot, thereby limiting the insertion between the plug 2 and the socket 1. The socket 1 is provided with an identification switch 4 that is directly opposite the socket 102, and the distance between the identification switch 4 and the socket 102 is adapted to the insertion length of the plug 2. The identification switch 4 can be triggered only when the plug 2 is fully inserted into the socket 102, so as to realize the effective insertion between the plug 2 and the socket 1.

[0030] This solution includes a locking rod assembly inside the socket 1 and an L-shaped slot 201 at the distal end of the plug 2. The L-shaped structure of the slot 201 creates a dead point at its bend 204. The locking rod 301 engages with the slot 201, thus restricting the plug 2 and preventing it from dislodging from the socket 102. This ensures the stability of the connection between the plug 2 and the socket 1. Furthermore, an identification switch 4 is installed inside the socket 1 to detect the insertion of the plug 2. Triggering the identification switch 4 determines whether the inserted plug 2 is compatible with the socket 1. This solution, through the locking rod assembly and the identification switch 4, provides a dual, effective connection guarantee between the plug 2 and the socket 1 from both mechanical and signal connection perspectives, ensuring a reliable and stable connection between them. The identification switch 4 in this solution is a micro switch, which can only be triggered when the plug 2 is fully inserted into the socket 1. Therefore, when the identification switch 4 is triggered by pressing the distal end of the plug 2, it indicates that the plug 2 compatible with the socket 1 has been fully inserted. Figure 2 and Figure 3As shown, the bottom of the socket 1 is provided with an identification module 5 for reading the plug 2. The plug 2 has a built-in RFID chip 6. The identification module 5 is provided with an identification board 501 that can read the RFID chip 6. When the identification switch 4 is triggered, the identification board 501 identifies the RFID chip 6 and transmits the read information to the operating system to confirm that the plug 2 is connected to an ultrasonic scalpel that is compatible with the operating system, ensuring correct connection and safe use, and effectively avoiding operational failures caused by mismatched connections.

[0031] Specifically, such as Figure 1 , Figure 5 , Figure 6 As shown, the L-shaped slot 201 has a first slot segment from the starting end 202 to its turning point 204, and a second slot segment from its turning point 204 to its ending end 203. The extension direction of the first slot segment is consistent with the insertion direction of the plug 2, so as to facilitate the locking rod 301 to slide into the L-shaped slot 201 as the plug 2 is inserted. The extension direction of the second slot segment is perpendicular to the insertion direction of the plug 2, so that the locking rod 301 can restrict the plug 2 after sliding into the second slot segment, preventing it from coming out from the opposite direction.

[0032] In the initial state, the rod portion of the locking rod 301 is located at the initial end 1011 of the arc-shaped limiting groove 101. As the plug 2 is inserted into the socket 102, the bottom end of the locking rod 301 slides from the starting end 202 of the slot into the L-shaped slot 201. In the final state, the rod portion of the locking rod 301 is located at the ending end 1012 of the arc-shaped limiting groove 101, and the bottom end of the locking rod 301 is located at the ending end 203 of the slot. The arc-shaped limiting groove 101 is provided on the housing of the socket 1 to limit the movement direction of the locking rod 301 while maximizing its smooth movement. The L-shaped slot 201 is provided on the housing of the plug 2 to form a dead point position for the locking rod 301, thereby limiting the movement of the locking rod 301.

[0033] like Figure 1 and Figure 5As shown, the transmission connector includes a first connecting rod 303 and a second connecting rod 304. The first connecting rod 303 is pivotally connected to the socket 1 via a first rotating shaft 306, forming a first pivot connection point 100. One end of the second connecting rod 304 is pivotally connected to the socket 1 via a second rotating shaft 308, forming a second pivot connection point 200. The other end of the first connecting rod 303 and the other end of the second connecting rod 304 are also pivotally connected, forming a third pivot connection point 300. The locking rod 301 is vertical. The locking rod is directly inserted at the third pivot connection point 300, and the line connecting the first pivot connection point 100 and the second pivot connection point 200 is parallel to the line connecting the starting end 202 and the ending end 203 of the L-shaped slot 201. The distance between the first pivot connection point 100 and the second pivot connection point 200 is less than the sum of the lengths of the first connecting rod 303 and the second connecting rod 304, so that the turning point 204 of the L-shaped slot 201 forms the dead point position of the locking rod 301. Through holes adapted to the first rotating shaft 306 and the second rotating shaft 308 are formed on the shell wall of the socket 1 at the first pivot connection point 100 and the second pivot connection point 200, respectively, to facilitate the installation of the first rotating shaft 306 and the second rotating shaft 308. This structure allows the locking rod 301 to be quickly pushed into the end of the slot 203 after passing through the turning point 204, and the locking rod 301 will not move in the opposite direction without external force, thus forming a locking effect and ensuring a stable and reliable connection between the plug 2 and the socket 1.

[0034] The middle portion of the locking rod 301 is fixed within the second connecting rod 304. The other end of the first connecting rod 303 has an axially extending groove 3031. A first spring 309 is embedded within the groove 3031. The end of the first spring 309 abuts against the locking rod 301 and consistently exerts a pushing force on the locking rod 301. This structure ensures that the locking rod 301 is always located at the third pivot connection point 300, and the elasticity of the first spring 309 reduces hard contact between the locking rod 301 and the third pivot connection point 300, reducing wear on the locking rod 301 during movement and improving the smoothness of its movement.

[0035] Furthermore, a second spring 307 is embedded in one end of the second connecting rod 304, and a second retaining ring 305 is engaged on one end of the second rotating shaft 308 near the first connecting rod 303. The second spring 307 abuts against the inner wall of the second retaining ring 305 and the second connecting rod 304. The second spring 307 applies a downward pushing force to the second connecting rod 304, thereby applying downward pressure to the locking rod 301 to ensure that the bottom end of the locking rod 301 is slidably engaged in the L-shaped groove 201, achieving the purpose of the bottom end of the locking rod 301 sliding along the L-shaped groove 201.

[0036] Furthermore, the end of the first rotating shaft 306 is pivotally connected to the first connecting rod 303 via a first retaining ring 302.

[0037] To achieve a valid connection, the plug 2 has a set of pins 205 built in, and the socket 1 has a set of sockets 103 that match the pins 205.

[0038] The socket 1 has a set of limiting ribs 104 protruding from its shell wall. The extension direction of the limiting ribs 104 is consistent with the insertion direction of the plug 2. The plug 2 has a set of sliding grooves 206 recessed on its shell wall, which match the limiting ribs 104. The limiting ribs 104 and sliding grooves 206 can limit the insertion direction of the plug 2, preventing the plug 2 from deviating during insertion and causing excessive wear, thus improving the smoothness of the plug 2 insertion. On the other hand, they can further enhance the connection and tightness between the plug 2 and the socket 1, preventing them from separating.

[0039] Furthermore, a set of anti-slip ribs 207 are provided at intervals on the top or bottom of the plug 2 housing to increase the friction between the operator's hand and the plug 2, and to prevent the operator from inserting or pulling out the plug 2.

[0040] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0041] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
