BRIEF DESCRIPTION OF DRAWINGS

[0014] Fig. 1 is a schematic view of the utility model;

[0015] Fig. 2 is a schematic view in use.

[0016] Explanation of reference signs:

[0017] 1-base, 2-sheath support seat, 3-guide wire holder, 4-clamping groove, 41-opening part, 42-clamping seam part, 5-fixing sleeve, 6-sheath handle, 7-instrument, 8-guide wire. DETAILED DESCRIPTION

[0018] One specific embodiment of the utility model will be described in detail below in combination with the drawings, but it should be understood that the protection scope of the utility model is not limited by the specific embodiment.

[0019] As Figs. 1-2 indicated, the utility model embodiment provides a guide wire fixing device in vascular intervention, including base 1 and installing on base 1 sheath support seat 2 and guide wire holder 3.

[0020] Wherein, sheath support seat 2 is used to support sheath handle 6, guide wire holder 3 has clamping groove 4, and the width of clamping groove 4 decreases in its depth direction, clamping groove 4 is used to fix guide wire 8, so that before withdrawing instrument 7, guide wire is fixed in clamping groove 4 first, without fixing guide wire 8 with one hand, another hand withdraws instrument 7, that is, one hand can be liberated, so that instrument 7 is withdrawn more stably, and it is also relatively easy to operate.

[0021] As Fig. 1 indicated, the opening of clamping groove 4 faces upwards, and in other embodiments, the opening of clamping groove 4 can face the side or other directions.

[0022] In other embodiments, guide wire holder 3 is composed of two sub-holders, and clamping groove 4 is formed between the two sub-holders.

[0023] In addition, in order to prevent the loss of guide wire coating during fixing, a flexible polymer layer, such as a rubber pad, is arranged in clamping groove 4.

[0024] Clamping groove 4 includes opening part 41 and clamping seam part 42, the maximum width of clamping seam part 42 is not greater than the minimum width of opening part 41, and opening part 41 is V-shaped structure, and the fixation of guide wire can be completed by moving guide wire into clamping seam part 42.

[0025] In other embodiments, base 1 is made of metal material and is used for counterweight, so that the fixing device is not easy to move.

[0026] In other embodiments, base 1 is made of polymer material and is integrally formed with sheath support seat 2 and / or guide wire holder 3.

[0027] In addition, the bottom (back) of the base 1 can be provided with an adhesive layer, such as a tearable gel, for bonding with a disposable drape on the operating table to prevent the base 1 from being easily moved;

[0028] In addition, the sheath support seat 2 of the present embodiment is fixedly connected with a fixing sleeve 5 matched with the sheath, as shown in Fig. 1 The fixing sleeve 5 is a non-closed cylindrical structure, and the fixing sleeve 5 can be a metal spring leaf that can automatically reset after deformation, thereby achieving fixation of the sheath handle 6.

[0029] In addition, in order to reduce the distance between the sheath support seat 2 and the guide wire card seat 3 and shorten the length of the entire device, the sheath support seat 2 and / or the guide wire card seat 3 can be detachably mounted on the base 1, and the detachable mode is selected as plug-in, so that the sheath support seat 2 and the sheath handle 6 can be connected first, and then the sheath support seat 2 is plugged into the corresponding slot in the base 1 to perform subsequent work.
