Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
A clamp for a medical catheter or a guide wire comprises a first clamp body 1 and a second clamp body 2 which are hinged together through a rotating shaft 3 in the middle, wherein the rotating shaft 3 is located in the middle of the first clamp body 1 and the second clamp body 2. The rotating shaft 3 is sleeved with a torsion spring 4, wherein two ends of the torsion spring 4 are respectively connected with the opposite inner side surfaces of one end of the first clamp body 1 and the second clamp body 2, so that the opposite inner side surfaces of the other ends of the first clamp body 1 and the second clamp body 2 are abutted through the elasticity of the torsion spring 4 to form a clamping end 5 of the clamp.
At one end of the clamping end 5 of the clamp, as shown in fig. 2, the opposite surfaces of the first and second bodies 1, 2 are provided with a detachably connected clamping plate 6, respectively. The clamping plates 6 on the first clamp body 1 and the second clamp body 2 are arranged oppositely. When the first clamp body 1 and the second clamp body 2 are close by the elasticity of the torsion spring 4, the opposite clamping plates 6 are in contact.
Opposite surfaces of the clamping plates 6 are respectively provided with a full-length arc groove 63, wherein the length direction of the arc groove 63 is parallel to the axis of the rotating shaft 3. A layer of rubber pad 7 matched with the shape of the arc groove 63 is arranged on the inner surface of the arc groove 63, wherein the rubber pad 7 is fixed inside the arc groove 63 in a bonding mode. The surface of the rubber pad 7 is provided with a plurality of anti-skid stripes which are arranged in a cross way.
The clamping plate 6 comprises a fixing part 62 attached to the inner side surface of the first clamp body 1 or the second clamp body 2 and an extending part 61 extending from one side wall of the first clamp body 1 or the second clamp body 2, and the extending part 61 and the fixing part 62 are integrally formed.
Square holes 12 are respectively arranged on the surfaces of the first clamp body 1 and the second clamp body 2 which are jointed with the clamping plate 6. Opposite elastic insertion rods 621 are arranged on the surface of the fixing part 62 opposite to the square holes 12, and the opposite insertion rods 621 are fixedly connected with the clamping plate 6 or integrally formed. A space is left between the opposite insertion stems 621, and the distance between the facing surfaces of the opposite insertion stems 621 matches the width of the square hole 12. On the opposite side of the opposite plug stem 621, a latch 622 extending outward is disposed at one end of the plug stem 621 away from the fixing portion 62, and the latch 622 and the plug stem 621 are integrally formed. The fixture block 622 is located on the wedge-shaped block or the right-angled triangle-shaped block, the inclined surface of the wedge-shaped block or the right-angled triangle-shaped block is located on one side departing from the inserting rod 621 and faces one side away from the fixing portion 62, and the distance between the fixture block 622 and the fixing portion 62 is matched with the thickness of the first clamp body 1 or the second clamp body 2. The space between the opposite insertion rods 621 enables the insertion rods 621 to deform so as to allow the latch 622 to pass through the square hole 12 to fix the fixing portion 62 on the first clip body 1 or the second clip body 2.
The thickness of the end of the extending part 61 connected with the fixing part 62 is thicker than that of the fixing part 62, so that a step is formed between the extending part 61 and the fixing part 62, and when the clamping plate 6 is fixed on the first clamp 1 or the second clamp 2, the step between the extending part 61 and the fixing part 62 is clamped on the side wall of the first clamp 1 or the second clamp 2, so as to position the clamping plate 6 and facilitate the installation of the clamping plate 6.
The extending portion 61 has a gradually decreasing thickness and a gradually decreasing width from one end of the connection fixing portion 62 toward the free end of the extending portion 61. When the clip is used to clamp a medical catheter, the extension 61 is directed toward the end of the medical catheter, thereby reducing the obstruction of the extension 61 to the intubation process.
As shown in fig. 1, a turned-up edge 11 turned up to the side away from the second clamp body 2 is arranged at the end of the first clamp body 1 away from the clamping end 5, and the turned-up edge 11 and the first clamp body 1 are integrally formed.
When the intubation is performed, the medical catheter or the guide wire is clamped by the first clamp body 1 and the second clamp body 2 which are positioned on the clamping end 5, and the extension part 61 of the clamping plate 6 is positioned at the extending end of the medical catheter or the guide wire. The medical staff inserts the tube by holding the clip, and limits the medical catheter or guide wire by the extension part 61 on the clamping plate 6, so as to shorten the length of the soft part between the extending end of the medical catheter or guide wire and the holding position, thereby reducing the deformation of the medical catheter.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
