Description

Technical Field

[0001] This utility model relates to the field of plug technology, specifically to a medical wire harness plug. Background Technology

[0002] A high-frequency electrosurgical pen is an electrosurgical device that replaces traditional scalpels for tissue cutting. It heats the tissue through high-frequency, high-voltage current generated at the tip of an effective electrode, achieving tissue separation and coagulation, thus achieving cutting and hemostasis. High-frequency electrosurgical pen offers advantages such as preventing bacterial infection and promoting better postoperative healing, and is therefore widely used in surgical procedures. A high-frequency electrosurgical pen typically includes a surgical scalpel, a power cord, and a plug. For example, the invention patent with publication number "CN106725840A," entitled "A Fixable Disposable High-Frequency Electrosurgical Pen," discloses a fixable disposable high-frequency electrosurgical pen, which includes a blade head, a handle, a hand control button, a cable, a cable clamp, and a plug. While the plug allows for connection, the pins are evenly spaced, lacking a foolproof design. Careful identification of the correct orientation is required during insertion; otherwise, it is easy to insert it incorrectly, leading to malfunction and inconvenience during surgery. Utility Model Content

[0003] To address the aforementioned shortcomings, the purpose of this utility model is to provide a medical wire harness plug with a reasonable structural design and easy operation.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A medical wiring harness plug includes a housing, prongs, and a wire. The prongs are three in number, arranged side-by-side at the same horizontal level on the housing, with varying spacing between adjacent prongs. The wire extends into the housing and connects to the prongs. The upper surface of the housing has an arc-shaped recess, while the lower surface is flat. A sleeve is provided on one side of the housing, with a hole for inserting a cutting tip. The center line of the hole is parallel to the axis of the prongs. During storage, the cutting tip of a high-frequency electrosurgical pen can be inserted into the hole, protecting the cutting tip and allowing for convenient storage of the electrosurgical pen and plug.

[0006] As a preferred embodiment of this utility model, the arc-shaped recess is provided with anti-slip protrusions. When the user holds the plug for insertion, the anti-slip protrusions can increase the friction between the fingers and the plug surface, preventing the fingers from slipping on the plug surface, thus allowing for a more stable grip on the plug, facilitating the application of appropriate insertion force, accurately inserting the plug into the socket, and also facilitating the removal of the plug.

[0007] In a preferred embodiment of this invention, the anti-slip protrusion is an elongated strip and / or a circular dot. Elongated strips and circular dot are two common anti-slip structural forms that can increase the surface roughness of the plug, providing anti-slip protection in all directions. This allows fingers to better adapt to different force angles and directions when gripping the plug, thereby improving grip stability.

[0008] In a preferred embodiment of this utility model, the plug is a cylindrical tube with a hemispherical head. Four symmetrically arranged slots are formed on the front wall of the tube, creating four independent spring claws. The middle of each spring claw arches outwards, giving it elasticity and allowing it to deform appropriately when inserted into the socket, thus ensuring a tight fit with the contact area inside the socket and guaranteeing good electrical contact performance. The slots widen at the arched position, providing sufficient space for the elastic deformation of the spring claws, allowing them to deform more smoothly under force and enhancing the contact reliability between the plug and the socket. An arc-shaped recess is provided at the front end of the slot corresponding to the hemispherical position, providing better elastic support for the front deformation of the spring claws, facilitating plug insertion and extending service life.

[0009] As a preferred embodiment of this utility model, a reinforcing rod extending along its axial direction is provided inside the circular tube. There is a gap between the front part of the reinforcing rod and the inner wall of the circular tube, which provides a certain amount of deformation space for the spring claw. When the space exceeds the predetermined space, the reinforcing rod can play a supporting role, thereby improving the mechanical strength and deformation resistance of the pin. The tail part of the reinforcing rod is interference-fitted with the inner wall of the circular tube, which is tight, firm, and has a good assembly effect.

[0010] The beneficial effects of this utility model are as follows: The structure of this utility model is rationally designed. The three prongs are arranged side-by-side at the same horizontal level on the socket, with inconsistent spacing between adjacent prongs. This inconsistent spacing creates an asymmetrical structure, thus achieving a foolproof function. When the plug is connected to the socket, only when inserted in the correct direction can the prong spacing match the corresponding part inside the socket, thereby avoiding reverse insertion. Furthermore, due to the arc-shaped concave and flat surface design of the socket, medical personnel do not even need to carefully examine the prong structure; they can identify whether the plug is facing forward or backward simply by touch, thus completing the correct insertion operation. This reduces inconvenience caused by incorrect insertion during surgical procedures, making operation simple and convenient, and effectively improving work efficiency. In addition, when storing, the tip of the high-frequency electrosurgical pen can be inserted into the sleeve, protecting the tip while also allowing for convenient storage of the high-frequency electrosurgical pen and plug.

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0016] See the example. Figures 1 to 4 This embodiment provides a medical wiring harness plug, which includes a housing 1, pins 2 and wires 3. There are three pins 2, which are arranged side by side on the housing 1 at the same horizontal level. The spacing between any two adjacent pins 2 is not uniform. The wires 3 extend into the housing 1 and are connected to the pins 2.

[0017] See Figure 4 The pin 2 is a round tube with a hemispherical head. The front part of the tube has four symmetrically arranged slots 21 to form four independent spring claws. The middle part of the spring claw is arched outward in an arc shape 22. In this embodiment, the length of the pin 2 extending from the shell 1 is 15.5mm. The outer diameter of the pin 2 is 3.8mm, and the height of the arc-shaped arch 22 in the middle of the spring claw is 0.5mm. The arc-shaped arch 22 gives the spring claw a certain degree of elasticity, allowing it to deform appropriately when inserted into the socket, thus tightly fitting with the contact part inside the socket and ensuring good electrical contact performance. The slot 21 widens at the position corresponding to the arc-shaped arch 22, forming a widened part 211, providing sufficient space for the elastic deformation of the spring claw, allowing it to deform more smoothly under force, and enhancing the contact reliability between the pin 2 and the socket. The front end of the slot 21 has an arc-shaped recess 212 corresponding to the hemispherical position, providing good elastic support for the front deformation of the spring claw, facilitating the insertion of the pin 2 and extending its service life. Preferably, a reinforcing rod 4 extending along its axial direction is provided inside the circular tube, and the reinforcing rod 4 can be a plastic rod or a metal rod. The front part of the reinforcing rod 4 is radially reduced and has a gap with the inner wall of the round tube. The gap provides the spring claw with a certain amount of deformation space. When the space exceeds the predetermined space, the reinforcing rod 4 can play a supporting role, which improves the mechanical strength and deformation resistance of the pin 2. The rear part of the reinforcing rod 4 is radially increased and has an interference fit with the inner wall of the round tube. The fit is tight, firm and has a good assembly effect.

[0018] The upper surface of the plug housing 1 has an arc-shaped recess 11, and the lower surface is a flat surface 14. Preferably, the arc-shaped recess 11 has anti-slip protrusions. The anti-slip protrusions can be elongated strips, circular protrusions, or a combination of both. Elongated strips and circular protrusions are two common anti-slip structural forms that can increase the roughness of the plug surface. In this embodiment, a combination of both is selected. It plays an anti-slip role in all directions, allowing the fingers to better adapt to different force angles and directions when holding the plug, thereby improving the stability of the grip. When the user holds the plug for insertion, the anti-slip protrusions can increase the friction between the fingers and the plug surface, preventing the fingers from slipping on the plug surface, thus gripping the plug more stably, making it easier to apply appropriate insertion force, accurately insert the plug into the socket, and also facilitating the plug removal operation.

[0019] Preferably, a sleeve 12 can be provided on one side of the housing 1. The sleeve 12 has a socket 13 for inserting the tip of a high-frequency electrosurgical pen. The center line of the socket 13 is parallel to the axis of the pin 2. The socket 13 is flat and can accommodate round or flat tips. During storage, the tip of the high-frequency electrosurgical pen can be inserted into the socket 13, protecting the tip and allowing for convenient storage of the high-frequency electrosurgical pen and plug.

[0020] In use, because the three pins 2 are arranged side by side at the same horizontal level on the housing 1, and the spacing between any two adjacent pins 2 is inconsistent, such as Figure 2 The distance between the uppermost pin 2 and the middle pin 2 is 12.6mm, and the distance between the lowermost pin 2 and the middle pin 2 is 19.6mm. This inconsistent spacing forms an asymmetrical structure to achieve the foolproof function.

[0021] The wire 3 has three core wires: a neutral wire, a live wire, and a ground wire. The neutral wire is connected to the top pin 2, the live wire to the middle pin 2, and the ground wire to the bottom pin 2. The other end of the wire 3 is soldered to the circuit board of the high-frequency electrosurgical pen. When the plug is connected to the socket on the electrosurgical unit, the spacing between the pins 2 must be aligned with the corresponding parts inside the socket to prevent reverse insertion.

[0022] Moreover, during insertion, due to the arc-shaped recess 11 and flat surface design of the socket 1, medical staff do not even need to carefully examine the structure of the pins 2. They can identify whether the plug is facing up or down simply by touching it with their fingers, thus completing the correct insertion operation. The operation is simple and convenient.
