In the figure: 1. an instrument assembly, 11, a treatment assembly, 12, an outer pin tube, 13, a core bar connecting piece, 131,

The device comprises a buckle, 14, a control wire, 15, a control wire fixing piece, 2, a handle assembly, 21, a core bar, 211, a clamping groove, 22, a finger ring, 23 and a fixing bolt.

Detailed Description

The utility model is further described below. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and are not intended to limit the scope of the present utility model.

As shown in fig. 1, 2 and 3, a reusable endoscopic surgical instrument is composed of a main instrument assembly 1 and a handle assembly 2, wherein the handle assembly 2 is composed of a core bar 21, a finger ring 22 and a fixing bolt 23, and is made of a material capable of being sterilized repeatedly. Wherein the instrument assembly 1 is composed of an outer sheath 12, a control wire 14, a core bar connecting piece 13, a control wire fixing piece 15 and a treatment component 11.

The treatment assembly 11 is composed of and made of different structures and different materials according to different requirements of endoscopic surgery, and the core bar connecting piece 13 connected with the handle assembly 1 is a universal interface so as to meet the requirements of exchanging different instrument assemblies 1 and handle assemblies 2, and the instrument assembly 1 is in a sterilization state when leaving the factory and is disposable. As shown in fig. 4, when the core bar connecting member 13 and the core bar 21 are installed, the buckle 131 of the core bar connecting member 13 may be clamped in the clamping groove 211 of the core bar 21, so as to achieve effective connection between the core bar connecting member 13 and the core bar 21 and ensure mutual rotation between the two.

As shown in fig. 4, after the operation is completed, a certain force is applied in the axial direction of the core bar connector 13 and the core bar 21, so that the buckle 131 of the core bar connector 13 is separated from the clamping groove 211 of the core bar 21, and the core bar connector 13 and the core bar 21 can be separated.

As shown in fig. 5, when the control wire fixing member 15 and the finger ring 22 are mounted, the fixing portion 151 of the control wire fixing member 15 is clamped in the clamping groove 221 of the finger ring 22, and the upper end is locked in the finger ring 22 by the fixing bolt 23, so that the effective connection between the control wire fixing member 15 and the finger ring 22 is achieved.

As shown in fig. 5, after the operation is completed, the fixing bolt 23 is loosened, and the control wire fixing member 15 of the instrument assembly 1 is removed, so that the control wire fixing member 15 and the finger ring 22 can be separated.

After the device is used, the device assembly 1 is used for disposing according to medical device garbage. The handle assembly 2 is sterilized according to the repeated sterilization management method of the using unit for the next use. The structure of the utility model can effectively reduce the waste of disposable products in the endoscopic surgery and effectively protect the environmental requirements.
