In some embodiments, the cannula hub is removably attached to the proximal end of the cannula body, the distal end of the cannula body being provided with a cannula tip.

In some embodiments, the guide further comprises a protective sheath.

In some embodiments, the guide sleeve defines a cavity therein for placement of the guide.

In some embodiments, the head end of the cannula hub contains a luer fitting.

In some embodiments, the distal end of the catheter body and the cannula tip are tapered rounded structures.

The utility model discloses owing to adopt above technical scheme, make it compare with prior art, have following advantage and positive effect:

1. the utility model relates to a guiding device, the bending angle of the far end of the guider can be selected, and a doctor can select the guiding device with the proper bending angle as required in the interventional therapy process, thereby meeting the requirement of actual operation; 2. the utility model discloses a guiding device, the director with the cooperation of director sleeve pipe is used, the simple structure of subassembly, convenient operation.

Drawings

The above and other features and advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:

fig. 1 is a schematic view of a guide provided by the present invention;

fig. 2 is a schematic view of the guide sleeve provided by the present invention.

Detailed Description

The invention will be described in more detail hereinafter with reference to the accompanying drawings showing embodiments of the invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

Referring to fig. 1 to 2, the present invention provides a guiding device, which comprises a guider and a guider sleeve, wherein the guider is arranged in the guider sleeve;

referring to fig. 1, the guide device comprises a base body 1, a joint 2, a catheter body 3 and a protective sleeve 4 from the proximal end to the distal end; the head end of the seat body 1 contains a luer connector, and the other end of the seat body 1 is connected with the near end of the connector 2; the distal end of the adapter 2 is detachably connected to the proximal end of the catheter body 3; the distal end of pipe main part 3 is provided with the angle of inflection, and the distal end of pipe main part is toper rounding off structure, guarantees that guiding device has good propelling movement nature in operation process, and the distal end cover of pipe main part 3 is equipped with protective sheath 4, prevents that the distal end of pipe main part 3 from punctureing the extranal packing when guiding device independently packs. When the guider is horizontally placed, the axis of the near end of the catheter main body 3 is taken as a horizontal line, the inclination angle of the length of 10cm at the far end of the catheter main body 3 is measured, the outside line of 10cm at the far end of the catheter main body 3 is taken as a measuring line, and the inclination angle is the bending angle A of the guider.

In this embodiment, the bending angle of the guiding device can be set to be between 40 ° and 70 °, and preferably, two angles of 40 ° and 70 ° are selected as suitable bending angles, so that the guiding device can conveniently pass through the catheter connection part for guiding the direction of the distal end, and simultaneously adjust the medical device in the guiding device to a desired position.

In the present embodiment, the holder body 1 and the catheter body 3 are made of stainless steel, preferably 304 stainless steel, without limitation.

In this embodiment, the minimum separation breaking force between the catheter body 3 itself, the housing 1 and the connector 2, and between the catheter body 3 and the connector 2, which can be borne by the connector, is not more than 20N, and preferably 15N, which ensures the stability of the connection relationship.

Referring to fig. 2, the introducer sheath comprises, proximally to distally, a sheath hub 5, a sheath body 6, a sheath tip 7; the cannula holder 5 is detachably connected to the proximal end of the cannula body 6, the distal end of the cannula body 6 being provided with a cannula tip 7.

In this embodiment, the cannula tip 7 is tapered and rounded to ensure that the guiding device has good pushability during operation.

In this embodiment, the minimum break-away force that can be tolerated between the cannula body 6 itself, the cannula body 6 and the cannula holder 5 is not more than 20N, preferably 15N ensuring a stable connection.

It will be appreciated by those skilled in the art that the invention can be embodied in many other specific forms without departing from the spirit or scope thereof. Although embodiments of the present invention have been described, it is to be understood that the present invention should not be limited to those precise embodiments, and that various changes and modifications can be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined by the appended claims.
