Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element. Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of the present application is not limited to performing the functions in the order shown or discussed, but may also include performing the functions in a substantially simultaneous manner or in an opposite order depending on the functions involved, e.g., the described methods may be performed in an order different from that described, and various steps may be added, omitted, or combined. Additionally, features described with reference to certain examples may be combined in other examples.
In various embodiments of the present application, "proximal" and "distal" refer to the proximal and distal positions of an endoscope operating section relative to a user when the associated plug is inserted into another plug of the connector in a use environment. Wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".
In the present application, the pin body is configured to be capable of being inserted into the insertion hole 11, and the pin body and the insertion body 1 may be considered as a component of two plugs (one male plug and one female plug) in one connector, the pin body and the blind end of the insertion hole 11 are both used for inserting pin needles, the pin needle inserted into the blind end of the insertion hole 11 may be a male pin needle or a female pin needle, and the pin needle mounted on the pin body should be a female pin needle or a male pin needle, and the pin needles inserted into the insertion hole 11 and the pin needles inserted into the pin body are distinguished by the first pin needle 4 and the second pin needle.
In the related art, in order to ensure the disposable requirement of the endoscope operation part, the disposable requirement is ensured by limiting the use time of a single endoscope operation part through a self-destruction program, but the problem of the operation is that: 1. the limited use time, too short, may not allow for one-time endoscopic or therapeutic procedures; 2. if the limited service time is too long, the risk of being reused exists; 3. there is a risk of being taken for reuse by releasing the duration limit by modifying the self-destructing procedure.
The inventors found that it is very difficult to limit the disposable use of the endoscope operation section by the self-destruction procedure, and the problem of multiplexing cannot be effectively avoided, but if the connection structure is broken from the physical form by the hand of the communication connection structure between the endoscope operation section and the display device, multiplexing of the endoscope operation section can be more effectively avoided.
Accordingly, there is provided a communication connection structure capable of being forcibly destroyed after one use of an endoscope operation section, which is effective in solving the problem of multiplexing the endoscope operation section, but unfortunately, there is no communication connection structure capable of being forcibly destroyed after one use, which satisfies the above-mentioned requirements.
Accordingly, the inventors herein have provided a plug structure in a plug of a connector for an endoscope operation section from below a communication structure employed by the endoscope operation section, designed as a disposable assembly, and provided a plug employing the disposable plug structure and an endoscope operation section employing the plug.
On the one hand, the invention provides a disposable plug structure, which is used as a main component of a plug in a connector, and can destroy the communication connection function of the plug through the function provided by the disposable plug structure by one-time plug action so as to achieve the purpose of disposable use, thereby effectively ensuring that an endoscope operation part of the plug adopting the disposable plug structure can be destroyed after disposable use and cannot be reused. As shown in fig. 1 to 9, the following structure is provided in particular;
In this embodiment, the disposable plug structure includes a plug body 1, an elastic member 2, and a traction body 3.
The plug body 1 belongs to a part of a connector, wherein one end of the plug is provided with the part, and the part can be structurally improved or redesigned based on the existing plug, but at least the plug body 1 and the pin body can be ensured to complete connection and disconnection according to the existing axial plug formula.
Basically, the plug body 1 has an axial insertion hole 11, the insertion hole 11 is a blind hole for receiving a pin body matched with the hole pattern thereof, the hole pattern of the insertion hole 11 can be circular, but can also be rectangular, oblong, triangular, etc., and the blind end of the insertion hole 11 is used for connecting the first pin needle 4. The plug body 1 further has a locking structure 12, and the locking structure 12 is formed on the wall of the insertion hole 11 and is used for cooperating with the elastic member 2 to lock the elastic member 2. The plug body 1 is further provided with a through hole 13, the through hole 13 penetrates the plug body 1, and the plug hole 11 is communicated with the outside for penetrating the traction body 3.
The elastic member 2 can store energy through self deformation, and returns to a natural state to release energy after the external force is relieved. The elastic piece 2 is integrally arranged in the insertion hole 11, the first end of the elastic piece 2 is connected to the plug body 1, and the second end of the elastic piece 2 is positioned at the first position and is connected with the locking structure 12 in an aligned mode, so that the locking structure 12 provides axial braking and circumferential rotation stopping effects for the elastic piece 2, and the elastic piece 2 is kept in an energy storage state.
The traction body 3 comprises two end parts, is movably arranged in the perforation 13 in a penetrating way, and can move along the guide of the perforation 13 so as to adjust the protruding amount of the two end parts. One end of the traction body 3 is positioned in the insertion hole 11 and is connected to a part of the elastic member 2 which can move along the axial direction along with the energy storage, and the other end of the traction body 3 is positioned at the outer side of the insertion body 1 and is in a state of being not connected with other parts, so that the traction body 3 is ready to be connected with a wire connected with a wiring end of the first pin needle 4 penetrating through the blind end of the insertion hole 11.
Because the plug body 1 and the pin body are axially plugged, the plug of the pin body is used to realize the unlocking action of the elastic member 2 and the locking structure 12, and in general, the locking structure 12 presets an axial unlocking path for the second end of the elastic member 2, and at the same time, the second end of the elastic member 2 also presets a part for the pin body, which can realize axial abutting.
The unlocking mode provided by the unlocking path is as follows: during the continuous axial movement of the pin body towards the blind end of the insertion hole 11 after the pin body is axially inserted into the insertion hole 11, the end of the pin body abuts against the second end of the elastic member 2 and pushes the second end of the elastic member to a second position in which the axial braking and circumferential rotation stopping actions between the locking structure 12 and the elastic member 2 are released.
Under the basic setting structure, the elastic piece 2 arranged in the insertion hole 11 of the plug body 1 can be guaranteed to be installed in an energy storage state, and the second end of the elastic piece 2 is connected with the locking structure 12 arranged on the wall of the insertion hole 11 to realize locking, so that the elastic piece 2 can be kept in a stable state waiting for energy release and has the capability of outputting axial movement and circumferential movement. Meanwhile, the elastic member 2 is designed as a member that can be pushed toward the blind end of the insertion hole 11 by a pin body that is mated with the insertion hole 11, so that the elastic member 2 can be pushed by the pin body in the axial direction to release the locking relationship with the locking structure 12. After the locking structure 12 and the elastic piece 2 are unlocked, the pin body and the elastic piece 2 are mutually and axially abutted, and the elastic piece 2 can only rotate around the axial direction in a mode of releasing energy storage, so that the second end of the elastic piece is misplaced with the locking structure 12, and a condition that the elastic piece 2 cannot establish a locking relation with the locking structure 12 again in an axial resetting mode is created. When the pin body is drawn out of the insertion hole 11, the second end of the elastic member 2 is continuously abutted against the end of the pin body by releasing the energy storage, and moves towards the aperture of the insertion hole 11 along with the drawing out process of the pin body, so that the traction body 3 connected to the elastic member 2 can be pulled to shorten the length outside the insertion hole 1, and when the second end of the elastic member 2 moves to the third position (the third position is closer to the aperture of the insertion hole 11 than the second position), the elastic member 2 is in a natural state.
The disposable insertion and extraction structure has a function of pulling the lead wire connected to the first pin needle 4 by a pulling method. When the disposable plug-in structure is moved to the plug of the connector, the traction body 3 can be used for pulling the lead connected with the pin needle to break the electric connection between the lead and the pin needle so as to achieve the aim of forcedly breaking the connection function of the plug. When the disposable plug structure is applied to the plug of the connector matched with the disposable endoscope operation part, the disposable endoscope operation part has the function of destroying the communication connection capability after one-time plug, and the disposable plug structure can cause structural damage to the plug, compared with the prior art that the use of the disposable endoscope operation part is limited by a self-destruction program, the disposable plug structure can effectively ensure the disposable use of the endoscope operation part.
According to some alternative embodiments, as shown in fig. 2, 3, 5 and 6, the plug body 1 includes an outer tube 1a and a connector 1b, where the connector 1b is tightly matched with the outer tube 1a through shaft hole matching, so that the connector 1b seals the proximal end of the outer tube 1a, and an insertion hole 11 is formed in the outer tube 1 a. A clamping structure is arranged on the pipe wall of the outer pipe 1a near the orifice (distal end) of the insertion hole 11, and is used for being matched with a clamping structure arranged on the outer pipe matched with the pin body. As shown in fig. 5, a positioning key 15 extending from the aperture toward the blind end along the axial direction is provided on the inner wall of the outer tube 1a, i.e., the wall of the insertion hole 11, and the positioning key 15 is used to cooperate with a positioning groove to realize foolproof when two plugs of the connector are inserted. The pin body corresponding to the insertion hole 11 is provided with a positioning groove.
According to some alternative embodiments, as shown in fig. 3 and 6, a specific structure of the elastic member 2 is shown, the elastic member 2 includes an elastic body 2a and a movable body 2b driven by the elastic body 2 a. The elastic body 2a connects the movable body 2b with the plug body 1, and the movable body 2b is connected with the locking structure 12 in an aligned manner by elastic force to realize locking.
As a first preferred embodiment of the movable body 2b and the locking structure 12, the general structure and the matching relationship are as shown in fig. 8, the movable body 2b is configured as a plate-shaped structural member, when the insertion hole 11 is a circular hole, the movable body 2b may be specifically configured as an arc-shaped plate, the outer arc surfaces of which are disposed opposite to and are closely attached to the hole wall of the insertion hole 11, and the axis of which coincides with the axis of the insertion hole 11. The locking structure 12 is provided as a radial protrusion, which is not limited in shape and structure, and is integrally formed with the positioning key 15, and as an extension of the positioning key 15 at the proximal end, the locking structure 12 is provided with a notch at the proximal end, which notch provides an axial stop surface 121 and a circumferential stop surface 122. The distal end of the movable body 2b extends into the notch, and is simultaneously abutted against the axial stop surface 121 and the circumferential stop surface 122 under the action of the elastic body 2a to realize locking. Part of the structure of the movable body 2b needs to be located outside the notch in the circumferential direction or the radial direction so that the pin body can be abutted against the movable body 2b through the end portion when inserted into the insertion hole 11.
Of course, the notch may be formed on the distal end of the movable body 2b instead of the proximal end of the locking structure 12, and its general structure may be seen in fig. 9.
As a second preferred embodiment of the movable body 2b and the locking structure 12. As shown in fig. 3, 5, 6 and 7, the movable body 2b is provided as a tube coaxially fitted with the insertion hole 11, and at this time, the insertion hole 11 should be provided as a circular hole, and the cross-sectional shape of the movable body 2b is, of course, identical to the cross-sectional shape of the insertion hole 11. One end of the movable body 2b is provided with an axial projection 2b1. The locking structure 12 is provided as a radial protrusion, which is not limited in shape and structure, and is integrally formed with the positioning key 15, and as an extension of the positioning key 15 at the proximal end, the locking structure 12 is provided with a notch at the proximal end, which notch provides an axial stop surface 121 and a circumferential stop surface 122. The lock structure 12 axially abuts against an end of the movable body 2b and circumferentially abuts against the axial projection 2b1. The axial bulge 2b1 of the movable body 2b stretches into the notch, and is simultaneously abutted against the axial stop surface 121 and the circumferential stop surface 122 under the action of the elastic body 2a to realize locking. Because the movable body 2b is a coaxially sleeved pipe body in the insertion hole 11, an axially extending avoidance structure 2b2 is arranged at the side of the axial protrusion 2b1, the avoidance structure 2b2 can be a groove formed on the outer wall or a notch, so that after the axial protrusion 2b1 and the locking structure 12 are unlocked, the movable body 2b can be driven by the elastic body 2a to perform circumferential rotation, the avoidance structure 2b2 can be aligned with the locking structure 12, and when the movable body 2b axially moves towards the orifice of the insertion hole 11 under the action of the elastic body 2a, the locking structure 12 and the positioning key 15 can enter the avoidance structure 2b2, so that the axial movement of the movable body 2b is not influenced. In the second preferred embodiment, the movable body 2b of the tube body is coaxially sleeved with the insertion hole 11, so that the axial movement and circumferential rotation of the movable body 2b can be stabilized, and the blocking in the movement process can be avoided.

In this way, when the movable body 2b rotates in the circumferential direction, the second slope 2b11 can be abutted against the first slope 123, so that the movable body 2b slides along the inclination direction of the first slope 123 under the axial force of the elastic body 2a, and the movable body 2b rotates in the circumferential direction. In this preferred embodiment, the elastic body 2a can drive the movable body 2b to complete a large-angle rotation under the condition of storing smaller torque, so that the elastic body 2a can be assembled under the condition of smaller torsion degree during assembly, thereby facilitating the installation of the elastic body 2a, and simultaneously, the requirement on the torsion resistance of the elastic body 2a can be reduced.
In some alternative embodiments, as shown in fig. 6 and 7, the elastic body 2a specifically employs a compression torsion spring, which is disposed coaxially with the insertion hole 11. The elastic body 2a is set to be a compression torsion spring, and the axial moving force and the circumferential rotating force can be simultaneously provided for the movable body 2b through a single part, so that the movement requirement of the movable body 2b is met.
Of course, the elastic element 2 may also be designed as a separate compression torsion spring, by which one end leg is directly connected to the plug body 1 and the other end leg is arranged as a nipple extending axially towards the opening of the insertion hole 11 for engagement with the locking structure 12. This can reduce the setting of the movable body 2 b.
According to some alternative embodiments, as shown in fig. 3, the traction body 3 may be a rope, a chain, a rod or a plate, but preferably a rope is used, because when the traction body 3 is set to be a rope, the effect that the traction body 3 only pulls the connected wire in one direction can be well ensured, and the situation that the elastic piece 2 is pushed by the pin body to push the traction body 3 to pull the connected wire to generate corresponding displacement, so that the welding point of the wire and the pin needle is damaged before use or the wire is torn before use can be avoided.

Of course, perforations 13 may also be formed in the wall of the outer tube 1a, such as by placing the insertion holes 11 in radial communication with the outside of the outer tube 1a, but this would allow the pulling body 3 to bypass from the outside of the outer tube 1a to the proximal end of the hub 1 b. Therefore, the through hole 13 preferably penetrates through the blind end of the insertion hole 11 along the axial direction, so that the distance from the inside of the insertion hole 11 to the outside of the insertion body 1, which is positioned at the connection point between the first pin needle 4 and the wire, is shorter, the use amount of the traction body 3 can be saved, the space in the insertion hole 11 is saved, in addition, the direction of the through hole 13 is consistent with the axial moving direction of the elastic piece 2, the smooth shuttling of the traction body 3 in the through hole 13 can be better ensured, the condition that the length of the traction body 3 positioned outside the insertion body 1 cannot be reduced or cannot be reduced to a specified length capable of ensuring that the connection welding point between the pin needle and the wire is broken or ensuring that the wire is pulled off due to the moving blockage of the traction body 3 can be effectively avoided, and the opportunity that the traction body can be reused is avoided, so that the disposable operation part of the endoscope can be more effectively ensured.

The compression torsion spring is accommodated in the annular groove 14 arranged at the blind end of the insertion hole 11, the axial section of the blind end for ensuring stable installation of the first pin needle 4 is utilized, so that the compression torsion spring occupies little or no space of the insertion hole 11, the disposable plug-in structure can be designed to be shorter under the condition of having related functions, and the use amount of the traction body 3 can be reduced at least, so that the production cost is reduced.
