Description

Technical Field

[0001] The utility model relates to the field of medical device connectors, and particularly to an ultrasonic surgical knife handle connector with the characteristic of preventing cross-infection. Background Art

[0002] An ultrasonic scalpel is a high-frequency electrosurgical device, which not only has the cutting function of a mechanical scalpel, but also has functions such as tumor aspiration resection, liposuction, and blood coagulation. Moreover, it can be applied to both open surgeries and endoscopic surgeries at the same time. In recent years, due to its many excellent characteristics, it has been widely popularized in clinical surgeries.

[0003] In the prior art, the handle plug of a high-frequency ultrasonic scalpel is positioned as a reusable component, mainly composed of a signal connector socket core, an aluminum alloy metal shell and a polymer soft plastic. With the metal shell as the main body, it is wrapped with soft plastic, and the soft plastic and the metal shell body are combined at the middle position. However, due to the huge molecular difference between the soft plastic and the metal shell, the bonding at the joint of the soft plastic wrapping and the metal shell is not firm, and large gaps will be generated during repeated use. These gaps will become the best places for the hidden reproduction of microorganisms such as bacteria and viruses, and it is very difficult to clean and disinfect after surgery, which is likely to cause cross-infection due to incomplete disinfection.

[0004] In view of this, the technical solution of this application proposes an ultrasonic surgical knife handle connector with the characteristic of preventing cross-infection. By adopting an interference fit between the outermost metal shell and the tail (wire inlet part) of the plastic shell, the elimination of gaps is realized, preventing the hidden growth of microorganisms such as bacteria and viruses, and thus eliminating the possibility of cross-infection. Summary of the Utility Model

[0005] The technical solution of the utility model aims to solve at least one of the technical problems in the related art to a certain extent. For this reason, the main purpose of the utility model is to provide an ultrasonic surgical knife handle connector with the characteristic of preventing cross-infection, aiming to solve the problem of cross-infection caused by the loose connection of the ultrasonic scalpel shell in the prior art, which is easy to hide dirt and cause the growth of microorganisms such as bacteria and viruses.

[0006] To achieve the above purpose, the utility model provides an ultrasonic surgical knife handle connector with the characteristic of preventing cross-infection, including a connector main body composed of an internal component main body and a shell assembly.

[0007] The shell assembly includes a metal shell and a sheath shell sleeved outside the internal component main body. One end of the metal shell contracts inward to form an inward flange, and there is an external layer boss at one end of the sheath shell. The metal shell and the sheath shell are connected in a closed manner through the interference fit between the inward flange and the boss.

[0008] As a further solution of the present utility model, the outer part of the internal component body is coated with an inner metal shell as a shielding layer. Threads are provided on the surface of the inner metal shell, and the metal outer shell is connected to the inner metal shell through the threads.

[0009] As a further solution of the present utility model, the sheath shell is a plastic shell structure.

[0010] As a further solution of the present utility model, epoxy resin is filled inside the inner metal shell.

[0011] As a further solution of the present utility model, a sealing ring that closely adheres to the inner wall of the metal outer shell is sleeved outside the inner metal shell.

[0012] As a further solution of the present utility model, thread glue is applied to half of the surface of the threads, and the application position is close to the side of the inner edge.

[0013] The beneficial effects of the present utility model are as follows:

[0014] The ultrasonic surgical knife handle connector with the characteristic of preventing cross-infection proposed by the present utility model realizes the sealing of one side through the interference fit structure of the metal outer shell and the sheath shell, making the connection gap where the edge of the metal outer shell is embedded between the sheath shells very small. The physical structure is used for plugging, thereby effectively preventing foreign matters such as residual human tissues during the operation from entering the gap, and realizing the characteristic of preventing the hidden growth of microorganisms such as bacteria and viruses. In addition, due to the characteristics of the structure, the film opening and assembly efficiency are improved. BRIEF DESCRIPTION OF THE DRAWINGS

Description of the reference numerals of the main components / assemblies

[0022] Reference numeral Name Reference numeral Name 1 Connector body 103 Boss 10 Housing assembly 104 Inner metal shell 100 Metal outer shell 105 Thread 101 Inner edge 11 Inner component body 102 Sheath housing 12 Wire Specific embodiments

[0023] Are as follows:

[0024] Please refer to the attached Figures 1-5 ,

[0025] The main structure includes a connector body 1 composed of an internal component body 11 and a housing assembly 10. The housing assembly 10 includes a metal shell 100 and a sheath shell 102 sleeved outside the internal component body 11. One end of the metal shell 100 contracts inward to form an inward flange 101, and an outer layer boss 103 is provided at one end of the sheath shell 102. The metal shell 100 and the sheath shell 102 are connected in a closed manner through the interference fit between the inward flange 101 and the boss 103.

[0026] The working principle is as follows:

[0027] It changes the connection structure of the housing part of the current same-type connector, that is, instead of connecting the two housings by non-chemical means (adhesion) or drilling holes, the connection between the metal shell 100 and the sheath shell 102 is changed by physical means. The inward flange 101 of the metal shell 100 "squeezes" the boss 103 of the sheath shell 102 to form an interference fit structure to achieve sealing. This is because the material of the metal shell 100 is harder, while the material of the sheath shell 102 is softer (generally made of silicone or other flexible plastic shells). When the sheath shell 102 is inside the inward flange 101, it is "squeezed" and pressed tightly to achieve sealing. When in use, after the connector body 1 is connected to the device, the external space of the sheath shell 102 and the metal shell 100 cannot communicate with the inside.

[0028] A preferred embodiment of the present utility model: An inner metal shell 104 serving as a shielding layer is provided outside the internal component body 11, and threads 105 are provided on the surface of the inner metal shell 104. The metal shell 100 is connected to the inner metal shell 104 through the threads 105.

[0029] The inner metal shell 104 not only has the function of fixing the internal terminal components, but also has the functions of shielding external signals and anti-interference. During assembly, the metal shell 100 can be sleeved from one side and then connected to the inner metal shell 104 through the threads 105.

[0030] A preferred embodiment of the present utility model: The sheath case 102 is a plastic case structure.

[0031] The sheath case 102 can be a plastic case with flexible characteristics or a silicone case. The flexible plastic case can fully cover the wire 12 to reduce the gap.

[0032] A preferred embodiment of the present utility model: The inner metal case 104 is filled with epoxy resin.

[0033] The filled epoxy resin is used to fix components such as internal terminals and wires 12 after curing, and also has the function of further improving the sealing performance.

[0034] A preferred embodiment of the present utility model: An outer metal case 100 is sleeved outside the inner metal case 104 with a sealing ring that closely adheres to the inner wall of the outer metal case 100.

[0035] A preferred embodiment of the present utility model: Thread glue is applied to half of the surface of the thread 105, and the application position is close to the inner edge 101 side.

[0036] The thread glue is only applied to half of the thread 105, which not only achieves the double-sealing effect together with the sealing ring but also plays the role of conducting the inner and outer metal cases.

[0037] The above are only preferred embodiments of the technical solution of the present utility model, and do not limit the patent scope of the technical solution of the present utility model. Any equivalent structural transformation made under the inventive concept of the technical solution of the present utility model by using the description and drawings of the technical solution of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the technical solution of the present utility model.
