Description

  In the present invention, after percutaneous endovascular angiography and percutaneous angioplasty through the thigh, wrist, armpit, etc., the incision site is compressed by a compression mechanism after being attached to a finely incised surgical site. The present invention relates to a compression tourniquet that stops bleeding.

  Generally, after percutaneous endovascular angiography and percutaneous angioplasty through the thigh, wrist, armpit, etc., hemostasis is required at the surgically cut surgical site. Conventionally, hemostasis of such a surgical site has been performed simply by using a band, cotton or the like, but the hemostasis effect is low, and hemostasis has been accompanied by many difficulties.

  In order to solve such problems and to effectively press and stop the finely incised surgical site, a hemostatic band using a balloon, a physical compression disk, an intravascular vessel using expensive collagen Various hemostatic devices such as hemostatic devices, intravascular surgical devices using surgical sutures, and clips have been disclosed.

  A compression tourniquet using the balloon is simple and easy to use, but it cannot apply sufficient compression necessary for hemostasis. Furthermore, the physical compression disk has the disadvantage that after the hemostasis is performed, the sand bag must be placed on the surgical site for a long period of time, and the hemostasis instrument using the collagen and the intravascular surgical instrument using the suture, Since clips and the like are expensive and complicated to use, there is a drawback that the use failure rate is high.

  More specifically, as shown in FIGS. 1 and 2, a conventional compression tourniquet band using the balloon includes a balloon 3 having an air injection valve 2 connected at the center and a band portion formed around the balloon. It consists of five.

  The compression tourniquet is bonded to the band 5 in a state where the lower end of the balloon 3 is accurately positioned at the surgically cut surgical site, and then air is supplied to the balloon 3 so that the balloon 3 While inflating, press on the surgical site to stop bleeding.

  However, since the compression tourniquet using the balloon presses the surgical site due to inflation of the balloon due to air pressure, it is difficult to obtain a sufficient compression force, thereby significantly reducing the hemostatic effect. There was a point.

  In addition, since the inflated balloon has a hemispherical compression part, it is not easy to use it so as to be accurately positioned on the surgical part, and this effectively compresses the surgical part. There was a problem that could not be.

  The present invention has been made to solve the above-mentioned problems and various problems of the prior art, and percutaneous angiography and percutaneous angioplasty through the thigh, wrist, armpit, etc. After that, there is an object to provide a compression hemostatic band that maximizes the hemostatic effect by providing a sufficient compression force by pressing a finely incised surgical site with a compression member that is not a conventional balloon. .

  Another object of the present invention is to make it possible to very easily perform the operation of accurately pressing the wide compression surface of the compression member positioned at the surgical site where the incision is finely cut, thereby maximizing the hemostatic effect. Is to provide a strong compression tourniquet.

  Still another object of the present invention is to provide a band that is attached to a surgical site or is worn so as to wrap a body part such as a wrist and an ankle, and a compression member that maximizes the hemostatic effect by enhancing the compression effect of the compression member. To provide a hemostatic band.

In order to achieve the above object, the present invention provides:
A compression mechanism that compresses a finely incised surgical site after percutaneous endovascular angiography and percutaneous angioplasty through the thigh, wrist, armpit, etc .;
A band portion provided around the compression mechanism and detachably attached to a body part;
The compression mechanism includes a main body having a screw hole in the center, a knob having a screw portion screwed into the screw hole of the main body, and a tip of the knob, and the incision while moving forward and backward with respect to a body part. A compression hemostasis band is provided that includes a compression member having a compression surface adapted to compress a surgical site that has been performed.

  In the compression tourniquet as described above, an annular insertion protrusion is formed at the tip of the knob, and an annular receiving groove into which the annular insertion protrusion is rotatably inserted is formed inside the compression member, The annular insertion protrusion has a locking projection, and the annular receiving groove has a locking recess that prevents the compression member from coming off by the locking projection of the insertion protrusion.

  In the compression tourniquet as described above, the compression surface of the compression member is a flat portion having a large area.

  In the compression tourniquet as described above, the compression member has a recess on the outer periphery.

  In the compression hemostatic band as described above, the band portion is provided with extended portions made of Velcro fasteners on both sides so as to wrap the body part.

  The compression tourniquet of the present invention provides a compression force that is more effective than conventional balloon compression by a compression member that advances by a screw action of a knob to a finely incised surgical site, and without requiring another air injection. Since it can be used, the convenience of use is maximized, and the compression surface of the compression member is formed on a flat area with a large area, or the band part is worn around the body part such as the arm or ankle. By doing so, the work to be accurately worn on the surgical site is made much easier than before, and the hemostatic effect due to compression of the surgical site is enhanced, and the reliability in use is maximized.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  Referring to FIGS. 3 to 5, the compression tourniquet of the present invention is finely incised after percutaneous endovascular angiography and percutaneous angioplasty through the thigh, wrist and armpits. A compression mechanism 10 that compresses the surgical site, and a band portion 30 provided around the compression mechanism.

  The compression mechanism 10 has a screw hole 16 formed in the center of a main body 15 and is formed by screwing a knob 20 having a screw portion 22 corresponding to the screw hole, and has a compression surface 26 at the tip of the knob. The compression member 25 is combined, and the compression member performs a compression action while moving forward and backward by adjusting the rotation of the knob.

  An annular insertion protrusion 23 is formed at the tip of the knob 20, and an annular receiving groove 27 into which the annular insertion protrusion 23 is rotatably inserted is formed inside the compression member 25. The annular insertion protrusion 23 is formed with a locking projection 23a formed on the outer peripheral edge thereof, and the annular receiving groove 27 has a locking recess 27a that prevents the compression member 25 from being removed by the locking projection 23a. Have.

  The compression surface 26 of the compression member 25 is preferably a flat portion having a large area. In addition, the compression surface 26 may be formed in a rectangular shape in consideration of the fact that a finely cut surgical site is formed long.

  The band portion 30 is preferably formed of an inelastic material in order to increase the compression force of the compression mechanism 10. The band portion 30 has an adhesive layer and extends long in both directions from the main body 15 of the compression mechanism 10. Reference numeral 32 denotes a release paper that is detachably attached to the adhesive layer of the band portion 30.

  Next, the operation of the new compression tourniquet configured as described above will be described.

  First, after removing the release paper 23 of the band portion 30 of the present invention, the compression surface 26 of the compression member 25 is used for percutaneous endovascular imaging and percutaneous angioplasty through the thigh, wrist, armpit, and the like. After the operation, it is adhered so as to be located at a surgically cut surgical site. At this time, since the compression surface 26 of the compression member 25 is formed of a flat portion having a large area, the operation to be positioned at the surgical site is facilitated.

  Thus, if the knob 20 is rotated while attached to the surgical site, the screw portion 22 of the knob 20 is screwed into the central screw hole 16 of the main body 15 to move forward, and as shown in FIG. As a result, the compression member 25 coupled to the tip of the knob 20 moves forward.

  At this time, since the annular insertion protrusion 23 at the tip of the knob 20 is rotatably inserted into the annular receiving groove 27, the compression member 25 does not rotate when the knob 20 is rotated. Only the forward movement is performed by the screw movement operation. As described above, the compression surface 26 of the advancing compression member 25 exerts a hemostatic action while compressing the surgically cut surgical site.

  Further, since the compression member 25 provides a compression force by the knob 20 being screwed into the main body 15 and moving forward, the compression member 25 has a compression force much superior to the compression using a conventional balloon. Will provide. Further, the compression surface 26 having a large area of the compression member 25 can effectively compress the surgical site, thereby providing an excellent hemostatic action.

  Further, when the compression force on the surgical site by the compression member 25 is to be slightly relaxed, the compression member 25 at the tip of the knob is moved backward by rotating the knob 20 in the reverse direction. This indicates that the compression tourniquet in the present invention can adjust the compression force on the surgical site by the user.

  7A and 7B of the accompanying drawings show another embodiment of the compression member of the present invention. The compression member 25 shown in these drawings is one in which a “V” -shaped recess 28 is formed on one outer peripheral edge of the compression member 25, but the overall shape is different from each other.

  The reason why such a recess 28 is formed is that, as shown in FIG. 8, a tube, a sheath 50 or the like inserted into a blood vessel is extracted outside through the recess 28. In this structure, the above-described compression and hemostasis action is performed by positioning a notch portion for pulling out the tube or sheath 50 inserted into the blood vessel in the “V” -shaped recess 28 of the compression member 25. In other words, the compression and hemostasis are performed in a state where the notch portion is wrapped by the recess 28 of each compression member 25. By extracting the tube, the sheath 50, and the like inserted into the blood vessel in such a state, the extraction operation can be performed with minimal bleeding and pain.

  FIG. 9 of the accompanying drawings shows another embodiment of the present invention. Unlike the above-described preferred embodiment, this embodiment is an extension portion 35 having Velcro fasteners 36, 36 on both sides of the band portion 30. 35 is extended to wrap around the arm, wrist, ankle and other body parts. The use of the Velcro fastener 36 is for avoiding a reduction in the compression effect at the surgical site due to a relatively weak adhesive force of the adhesive layer of the band portion 30 in the above-described embodiment. By wrapping wrists, ankles, and other body parts with both side extension parts 35 of the band part 30 and attaching them to each other by using a Velcro fastener 36, the compression member 25 firmly compresses the surgical part, thereby providing a hemostatic effect. Can be increased.

  As described above, the compression tourniquet of the present invention provides a compression force that is more effective than conventional balloon compression by a compression member that is advanced by a screw action of a knob to a surgically cut surgical site. It can be used without air injection, so that the convenience of use is maximized, and the compression surface of the compression member is formed in a flat portion having a large area, or the arm or ankle in the band portion. By wearing it so that it wraps around the body part of the body, the operation to wear on the surgical site accurately is made much easier than before, and the hemostatic effect due to compression of the surgical site etc. is enhanced and the reliability in use is maximized. Has an effect.
