Description

Technical Field

[0001] This utility model relates to the field of ultrasonic scalpel composite wire harness technology, specifically to an ultrasonic scalpel composite wire harness. Background Technology

[0002] The ultrasonic surgical scissor is a high-end surgical instrument that combines ultrasonic energy with mechanical shearing function. It achieves precise cutting and coagulation through high-frequency vibration and is widely used in general surgery, obstetrics and gynecology, urology and other fields. Its core components include the main unit, handle, blade, and wiring harness. The ultrasonic surgical scissor wiring harness is a connecting wire specially designed for surgical scissors, which can realize ultrasonic energy transmission, signal control and mechanical vibration transmission.

[0003] However, existing surgical scissor ultrasonic scalpel harnesses do not integrate the power cord and ultrasonic signal cord into a single harness. During use, the surgical scissor ultrasonic scalpel needs to be connected to multiple harnesses, which is inconvenient. Furthermore, the plug assembly of existing surgical scissor ultrasonic scalpel harnesses cannot be ultrasonically cleaned and sterilized. In addition, existing surgical scissor ultrasonic scalpel harnesses lack a foolproof design, which cannot help users quickly identify the plug assembly's insertion direction. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides an ultrasonic scalpel composite wire harness to solve the problems mentioned in the background.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: an ultrasonic scalpel composite wire harness, comprising a plug assembly and a cable assembly, wherein a crimper, an SR connector and an SR outer connecting sleeve are arranged sequentially from the inside to the outside at the middle of the end of the cable assembly away from the plug assembly, and an earphone jack and a metal pin are sequentially connected to the outside of the cable assembly, wherein a plastic male terminal is inserted and installed at the end of the metal pin away from the earphone jack.

[0008] The plug assembly includes a rigid rubber casing, inside which are disposed pins, a read-only memory, potting compound, and an iron core. A plug connection portion is disposed at the end of the rigid rubber casing away from the cable assembly. A soft rubber sleeve is fully wrapped around the outside of the rigid rubber casing and connected to the end of the plug connection portion. An iron core slot is provided inside the plug connection portion. A pin holder is also fixedly installed at the end of the plug connection portion away from the soft rubber sleeve.

[0009] Preferably, the cable assembly includes a sheath, the inner side of which is provided with a braided protective layer, and the inner side of the braided protective layer is provided with two identical first insulating sleeves, each of which contains a power conductor. The braided protective layer is also provided with a wrapping sleeve, and the wrapping sleeve contains two identical second insulating sleeves, each of which contains an ultrasonic signal conductor. The braided protective layer is also provided with a filler strip.

[0010] Preferably, the ultrasonic signal wire and power wire are made of tin-plated stranded soft copper wire, the wrapping sleeve is aluminum foil, the braided protective layer is a tin-plated copper wire braided sleeve, and the sheath is made of PVC material.

[0011] The above technical solution combines the power supply wire and the ultrasonic signal wire into a composite wire harness, enabling an integrated connection that eliminates the need for multiple wire harnesses and improves practicality.

[0012] Preferably, both the PIN pin and the iron core penetrate through the rigid rubber and extend to the outside of the rigid rubber, and the connection between the soft rubber sleeve and the plug connection is an adhesive connection.

[0013] With the above technical solution, the connection between the soft rubber sleeve and the plug connection is an adhesive connection, which can play a waterproof role, effectively preventing water from entering the plug assembly, and can be ultrasonically cleaned and disinfected.

[0014] Preferably, the PIN pins are gold-plated terminals, the number of PIN pin holders is the same as the number of PIN pins, and the PIN pins are located inside the PIN pin holders. The iron core and the iron core slot are connected by a plug-in connection, and the iron core and the PIN pins are connected to the rigid encapsulation adhesive by potting compound.

[0015] The above technical solution uses gold-plated terminals for the PIN pins to reduce contact resistance and speed up transmission efficiency. Furthermore, by setting an iron core inside the plug assembly, it can be directly magnetically connected, reducing operational difficulty and improving practicality.

[0016] Preferably, the top of the soft rubber sleeve has an inner groove, which is rectangular in shape and has beveled edges on all four sides.

[0017] The above technical solution provides an inner groove only at the top of the soft rubber sleeve. This not only makes it convenient for users to pinch the plug assembly during use, but also serves as a foolproof method, helping users quickly identify the insertion direction of the plug assembly.

[0018] Compared with the prior art, the present invention provides an ultrasonic scalpel composite wire harness, which has the following beneficial effects:

[0019] This highly user-friendly ultrasonic scalpel composite cable harness integrates the power cord and ultrasonic signal cord within a sheath. A single, integrated connection is achieved through a braided protective layer and wrapping structure, eliminating the need for multiple cable harnesses and improving practicality. A recessed groove at the top of the plug assembly facilitates gripping and prevents mistaken insertion, helping users quickly identify the correct orientation. The plug assembly, encapsulated with a soft rubber sleeve, hard rubber, and potting compound, is waterproof, effectively preventing water from entering. It also allows for ultrasonic cleaning and disinfection. An internal iron core enables direct magnetic connection, simplifying operation. Attached Figure Description
