Endoscopes generally include: the device comprises an insertion part for being inserted into the human body, a handle convenient to operate and a display device or a host for displaying the internal environment of a natural cavity of the human body, wherein the insertion part and the handle can be collectively called as an operation part, and the operation part and the display device are in communication connection through a connecting cable by adopting a connector; the endoscope can realize peeping and focus exploration and treatment of the interior of a human body through the matching of the three parts.
Since the insertion portion of the endoscope operation portion is required to enter the human body and the handle portion is provided with an instrument channel for guiding an instrument in and out, there are cases where the endoscope operation portion is contaminated. Endoscopy or treatment costs are high, and generally, it is required that the endoscope operation section is reusable, and although the reused endoscope operation section is sterilized, cross infection cannot be completely avoided, and in the case of high hygienic requirements, it is required that the endoscope operation section is disposable, that is, the endoscope operation section used each time is completely new and unused, so as to eliminate the risk of cross infection. This results in a disposable endoscope operating section. The disposable endoscope operation part is correspondingly improved in terms of materials and designs in some places, so that the production cost of the disposable endoscope operation part is lower than that of the reusable endoscope operation part, but the disposable endoscope operation part is still more expensive, and because the endoscope operation part needs to enter a human body through a natural human body channel to complete certain operations, the quality and the performance of the endoscope operation part need to be ensured to be stable and reliable, the function of the disposable endoscope operation part can still be kept normal after the disposable endoscope operation part is used once, and therefore, the disposable endoscope operation part is intentionally or unintentionally reused.
Therefore, how to effectively ensure that the disposable endoscope operation part after use cannot be reused has become a technical problem to be solved by those skilled in the art.

It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.

Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present application, it should also be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium. The specific meaning of the above terms in the present application can be understood as appropriate by those of ordinary skill in the art.
In the application, the electric plug of the application and the other electric plug belonging to the same electric connector are used for mutual insertion and matching to realize electric connection, the electric plug of the application can be a male plug or a female plug, and the pin needle arranged on the electric plug of the application can be a male pin needle or a female pin needle, wherein the pin needle penetrating through the blind end of the insertion hole 11 of the insertion tube 1 and the pin needle penetrating through the pin of the other electric plug are distinguished by a first pin needle 9 and a 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 method 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 inventor herein devised an electrical connection assembly for use in an electrical connector of an endoscope operation section from below a communication structure employed by the endoscope operation section, designed as a disposable assembly, and provided an endoscope employing the electrical connector.
In one aspect, the present application provides an electrical plug, which is used as a main component of an electrical connector and is electrically connected with another electrical plug of the electrical connector, so as to realize communication connection between an operation portion of an endoscope and a display device.

The extension 21 of the movable body 2 can axially enter the escape passage 23 during the axial movement of the extension 21 of the movable body 2 on the other side of the radial protrusion 12 closer to the opening of the insertion hole 11, thereby providing a sufficient axial movement space for the movable body 2. The movable body 2 of the pipe fitting and the insertion hole 11 are coaxially inserted and matched, so that the axial direction of the movable body 2 can be smooth, and blocking is not easy to occur, so that the reliability is influenced.
According to some alternative embodiments, as shown in fig. 5 and 6, the top end of the movable body 2 may be used to directly abut against the other electrical plug, or may directly abut against the other electrical plug through the extension 21 of the movable body 2, if the extension 21 is to directly abut against the other electrical plug, the radial thickness of the extension 21 is designed to be thicker, so that the extension 21 protrudes radially beyond the radial protrusion 12, so that the other electrical plug can contact with the extension 21 to push against the movable body 2 after being inserted into the insertion hole 11.
According to some alternative embodiments, as shown in fig. 2-3 and 5-7, the top end of the mobile body 2 is provided with at least one thrust arm 22 extending axially towards the aperture of the insertion hole 11, all the thrust arms 22 being arranged equidistant along Zhou Xiangyi along with the extension 21.

In this way, one side surface of the pushing arm 22 is used as the axial extension of the avoiding channel 23, and can be used for circumferentially pushing against the radial protrusion 12 to limit the circumferential rotation angle of the movable body 2, so that when the elastic force of the first pre-tightening spring 3 is too large, the avoiding channel 23 can be prevented from rotating to be misplaced with the radial protrusion 12, and the movable body 2 cannot move towards the orifice of the insertion hole 11 along the axial direction.

The traction body 5 is preferably a rope, because when the traction body 5 is arranged as the rope, the traction body 5 can be well ensured to only produce unidirectional pulling effect on the connected wire, and the situation that the wire and the welding point of the pin needle are damaged before use or the wire is pulled apart before use caused by corresponding displacement of the traction body 5 pulling the connected wire in the process that the movable body 2 or the second pre-tightening spring 4 is pushed by the other connector seat can be avoided. When the traction body 5 is a rope or a chain, a through hole 13 needs to be additionally formed in the insertion tube 1, so that the traction body 5 can be penetrated out from the hole wall or the blind end of the insertion hole 11 to the lower part of the insertion tube 1.

Preferably, the through hole 13 is formed by a semicircular groove 1b1 provided in the connector 1b and an inner peripheral wall of the outer tube 1 a. The direction of the through hole 13 is consistent with the axial moving direction of the movable body 2, so that the traction body 5 can be well guaranteed to smoothly shuttle in the through hole 13, and the situation that the length of the traction body 5 outside the insertion tube 1 cannot be reduced or cannot be reduced to a specified length capable of guaranteeing the connection of the broken pin needle and the lead in a short time due to the movement blocking of the traction body 5 can be effectively avoided, so that the disposable use of the endoscope operation part can be effectively guaranteed. Of course, the through-hole 13 may be formed in the side wall of the outer tube 1a, but is preferably formed in the plug 1b so as to penetrate the plug 1b in the axial direction.

The ring groove 14 allows the second pre-tightening spring 4 to occupy or not occupy the space of the insertion hole 11, so that the electrical plug of the application can be designed to be shorter under the condition of having related functions, and the usage amount of the traction body 5 can be reduced at least, thereby reducing the production cost.

If the pre-tightening elastic force of the first pre-tightening spring 3 is small, the extension part 21 cannot be moved to the other side of the radial protrusion 12 in one step, so that the second slope surface 211 at the top end of the extension part 21 is staggered and contacted with the first slope surface 1211 at the bottom end of the axial protrusion 121 in the circumferential direction to realize guiding engagement.
After the use is completed, the connecting cable 8 is pulled out, the other connector is gradually pulled out from the insertion hole 11, the movable body 2 is abutted against the first slope surface 1211 through the second slope surface 211 under the axial thrust of the second pre-tightening spring 4, the first slope surface 1211 and the second slope surface 211 are matched to guide the extension part 21, the extension part 21 rotates along the circumferential direction against the friction force, the extension part 21 gradually rotates to the other side of the radial protrusion 12 in the process of moving towards the opening of the insertion hole 11, and then the extension part 21 passes through the side of the radial protrusion 12 and moves towards the opening of the insertion hole 11 along the axial direction, and meanwhile, the whole radial protrusion 12 gradually enters into the avoidance channel 23. Finally, the movable body 2 reaches the third position shown in fig. 7, at this time, the movable body 2 has driven the traction body 5 to displace the cable wire 81, so that the welding point between the cable wire 81 and the first pin 9 is damaged or the cable wire 81 is directly broken. So that the endoscope body using the plug of the present invention cannot be reused. When the movable body 2 reaches the third position, the portion of the pushing arm 22 of the movable body 2 protrudes from the orifice of the insertion hole 11.
