Medical intervention catheter or guide wire fixing clip

Abstract

The invention relates to a medical intervention catheter or guide wire fixing clip. The clip comprises an upper clip body, a lower clip body, a rotating shaft and a torsional spring, wherein the upper clip body and the lower clip body respectively comprise a clamping part at the front end and a handle part at the rear end; the middles of the upper and lower clips are hinged through the rotating shaft; the torsional spring is arranged on the rotating shaft in a sleeving manner; one end of the torsional spring is connected with the handle part at the rear end of the upper clip body, and the other end of the torsional spring is connected with the handle part at the rear end of the lower clip body; a clamping cavity is formed between the clamping parts of the upper and lower clip bodies; front and back parts of the clamping cavity are joint parts of the two clamping parts; an upper half sponge body and a lower half sponge body, which correspond to the upper clip body and the lower clip body, are embedded in the clamping cavity; the two half sponge bodies are compressed together under a normal state; the surfaces, corresponding to sponge body mounting positions, of the clamping parts of the upper and lower clip bodies are provided with a plurality of wetting through holes. The fixing clip is simple in structure and high in clinical practicability, does not damage a catheter or a guide wire, fixes the catheter or the guide wire firmly, can wet the guide wire, provides great convenience for clinical interventional operation, and is suitable for implementation.

Description

technical field [0001] The invention relates to a fixing device for guide wires and catheters used in interventional operations, in particular to a medical intervention catheter or guide wire fixing clip. Background technique [0002] At present, interventional surgery has been rapidly developed in the fields of cardiovascular and cerebrovascular diseases, tumors and non-vascular diseases due to its minimally invasive and effective advantages. In interventional surgery, the guide wire is the most basic equipment for surgery. Various guide wires of different specifications will be used in interventional surgery. The length of the guide wire is mostly greater than 150cm, and the longer one can reach 300cm. It will be replaced repeatedly, and some guide wires will be placed in a standby state when the guide wire is replaced. Place it on the instrument table. However, the above treatment methods all have disadvantages. If there are too many guide wires, they are all placed in ...

Problems solved by technology

Chinese patent document CN100466991C discloses a clamping protector for a vascular interventional guide wire, the main body of which is a jig that can hold a guide wire by two hard components capable of opening and closing. There is a connecting mechanism connected with the operating table, and its structure is complex, which is not convenient for clinical application and maintenance

The clamping parts in these existing clamping devices are all flat plate or meshing teeth. This structure directly clamps the guide wire. If the clamping is too tight, the guide wire may be damaged, especially the micro guide wire. If the clamping is slightly loose Potential to cause the guide wire to pop out of the V-shaped opening of the two splints, causing contamination of the guide wire

Moreover, most of the clamping devices in the prior art are only for clamping the guide wire. Although some can be applied to catheters, the plate-shaped or meshing tooth-shaped structure of the clamping part causes the clamping to be loose and the clamping effect is not good. If the clamping is too tight, it may cause damage to the catheter. In severe cases, the catheter may be closed and affect the operation. Therefore, it is not easy to control the clamping force and it is inconvenient to operate.

In addition, none of the above existing clamping devices can directly wet the hydrophilic guide wire, and most of the guide wires held by them need to be re-wetted in heparin saline before they can be used again.
