Description

High-frequency endoscope instrument with voltage-resistant structure and surgical robot

Technical Field

The utility model belongs to the technical field of endoscopic high-frequency surgical instruments, and particularly relates to a high-frequency endoscopic instrument with a voltage-resistant structure and a surgical robot.

Background

The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.

The high-frequency endoscopic surgical instrument is used for laparoscopic minimally invasive surgery. The high-frequency endoscopic surgical instrument is connected to the high-frequency surgical equipment through a cable, and converts high-frequency current into heat energy, so that the clinical functions of coagulation and cutting are realized. Since the voltage required for high-frequency operation varies from several hundred volts to several kilovolts, the insulation of the high-frequency surgical instrument requires high withstand voltage requirements, such as: high-frequency voltage of 1.2 times rated voltage and power frequency withstand voltage of 1000+ rated voltage.

The high frequency endoscopic surgical instruments are passed into the body through channels of the endoscope or instrument control system, requiring some degree of stiffness to effect external control of the instrument orientation. In order to achieve certain hardness, the outer layer braided extruded tube of the high-frequency endoscopic surgical instrument is often added with a metal braided mesh. Although the use of braided extruded tubes without metal mesh can also improve pressure resistance, the overall hardness of the device is too low to meet clinical requirements without metal mesh. In the prior art, when the outer layer of the device is entirely covered with a layer of insulating material (such as a heat shrink tube), the pressure resistance can be improved, but the inventor finds that the outer diameter of the high-frequency endoscopic surgical device is increased, which affects the use effect of the high-frequency endoscopic surgical device.

As used herein, the singular is also intended to include the plural unless the context clearly indicates otherwise, and furthermore, it is to be understood that the terms "comprises" and/or "comprising" when used in this specification are taken to specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof.

Example 1

The present embodiment provides a high-frequency endoscopic instrument having a withstand voltage structure, which includes an instrument head 1 and an extrusion tube 2 connected thereto.

Wherein the extruded tube 2 comprises a first braided extruded tube 2-2 and a second braided extruded tube 2-1; the first braiding extrusion pipe 2-2 is close to the front end instrument head, and the second braiding extrusion pipe 2-1 is far away from the instrument head; only the second braided extrusion tube 2-1 is pre-embedded with a metal mesh.

In a specific implementation process, the first woven extruded tube 2-2 and the second woven extruded tube 2-1 are integrated.

The tool head 1 of the present embodiment is a metal tool head.

In order to facilitate the cleaning and disinfection of the high-frequency endoscopic instrument, the instrument head 1 is detachably connected with the first braiding extrusion pipe 2-2.

The high-frequency endoscope instrument with the withstand voltage structure is characterized in that two test points of the withstand voltage test of the high-frequency endoscope instrument with the withstand voltage structure are two test points of the withstand voltage test, and two poles of the withstand voltage test instrument are respectively placed. One test point B is arranged at the position of the instrument head, and the other test point A is arranged at the set position of the second braiding extrusion pipe.

Fig. 1 is a conventional pressure-resistant design in which extruded tube 1 is a braided extruded tube, and all of the braided extruded tube is pre-embedded with a metal mesh. When breakdown is resisted, the current path is:

at point a, the woven extruded tube surface and the inner wire mesh break down, the current reaches point C (end of the inner wire mesh) along the wire mesh, then reaches the front metal portion along the creepage distance of the nonmetallic surface, and finally reaches test point B along the metal portion.

In this embodiment, the length of the test point distance B from the end D point of the first braided extrusion tube 2-2, which is arranged at the instrument head 1, is greater than 3mm/kV, the unit of the length is mm, and the unit of the rated voltage is kV.

Fig. 2 shows the breakdown path of the present embodiment. The point A and the point B are two test points for withstand voltage test, and two poles of a withstand voltage test instrument are respectively placed. When breakdown is resisted, the current path is: at point a, the woven extruded tube surface and the inner wire mesh break down, the current reaches point C along the wire mesh, the woven extruded tube surface and the inner wire mesh break down again at point C, then the current reaches the metal portion along the woven extruded tube surface from point C to point D, from point D to the surface of the instrument head insulation material, and finally reaches point B. Wherein, the point C is positioned at the connection point of the first braiding extrusion pipe 2-2 and the second braiding extrusion pipe 2-1, and the point D is the end point of the first braiding extrusion pipe 2-2 close to the instrument head 1.

Compared with the scheme of fig. 1, the creepage distance of the present embodiment increases the distance between C and D, and increases the breakdown point at point D. Therefore, the scheme of the embodiment greatly improves the pressure resistance of the instrument.
