Description

  The present invention relates to a hemostatic device.

  2. Description of the Related Art Conventionally, a technique for introducing various medical elongated bodies (for example, an introducer) into a blood vessel through a puncture site formed in a blood vessel of a patient's arm and performing treatment or treatment on a lesion site is known. . When such a procedure is performed, an operator or the like performs hemostasis of the puncture site when the medical long body is removed from the puncture site.

  As a hemostatic device used for hemostasis of the puncture site, a band for wrapping around a limb such as an arm, a fixing means for fixing the band in a state of being wrapped around the limb, and a fluid connected to the band And a pressing portion that expands and presses the puncture site is known (see Patent Document 1).

  The radial artery running on the human arm is connected to the palmar artery that bypasses the hand side (for example, the radial artery around the snuff box or the distal radial artery running on the fingertip side from the snuff box). Therefore, for example, an operator or the like can insert a medical long body into the radial artery running on the arm side by forming a puncture site in the palmar artery. In addition, when the puncture site is formed on the hand instead of the arm or wrist, the patient can move the arm while hemostasis is being performed (while the compression force is being applied to the puncture site). Since this becomes possible, the degree of freedom of movement of the body is increased and the quality of life (QOL) is improved.

  For example, an operator or the like needs to stop bleeding at a puncture site even when the puncture site for introducing a medical elongated body is formed on a hand as described above instead of an arm or a wrist.

Difficult to place. As an alternative hemostasis method, a method using a tape or the like is also conceivable, but it is difficult to obtain a sufficient hemostasis force, so that it is not an optimal method.

  Moreover, in the technique using the palm arteries, the punctureable site is not uniformly determined, and there are a plurality of locations along the blood vessel running, and the position, the depth of the blood vessel, and the like vary depending on the patient. For this reason, conventionally, there has been no hemostatic device configured to realize hemostasis with respect to a puncture site formed at an arbitrary location of the palm arteries.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a hemostatic device capable of appropriately hemostasing a puncture site formed at an arbitrary position of the palmar artery.

A pressing portion that presses a hemostatic site of the patient's hand arranged on the base portion and stops the hemostasis, and a pressing position adjustment that enables changing the pressing position of the pressing portion with respect to the patient's hand. Part.

  The hemostatic device is configured such that the patient's thumb is held in the holding portion while the patient's hand is placed on the base portion, and the patient's hand is fixed to the base portion by the fixing portion, so that the patient is in the middle of the procedure. Can be prevented from being displaced. In addition, since the position of the pressing portion that applies the pressing force to the puncture site formed on the patient's hand can be changed, the patient's palm arteries can be arbitrarily selected with the patient's hand fixed to the base portion. The pressing portion can be positioned at the puncture site formed at the position, and the puncture site can be appropriately stopped.

<Pressing part changing part>
The hemostatic devices 100 and 200 described in the above-described embodiments may include a pressing position adjustment unit described below. The pressing position adjustment unit is a structure for making it possible to change the type and / or number of pressing units.

  As shown in FIG. 7, the pressing portion changing portion 380 can be configured by a plurality of connection holes 381 formed in the pressing position adjusting portion 260 (see FIG. 4), for example.

  As the pressing part 340, for example, one having a pin-shaped tip part 341 that applies a pressing force to the puncture site t <b> 1 and a head part 342 that is held by the pressing position adjusting part 260 is used. it can. The pressing portion 340 can be connected to the connection hole 381 by, for example, a method such as screwing or fitting.

  The hemostatic device including the pressing unit changing unit 380 adjusts the position, number, type, insertion length into the connection hole 381, and the like of the pressing unit 340 to adjust the hemostasis according to the patient's physique, the position of the puncture site t1, and the like. Range and pressing force can be selected. For example, when the tip portion 341 of the pressing portion 340 has a thin rod shape like a pin as shown in the drawing, the pressing portion 340 concentrates the pressing force on a narrow area around the puncture site t1. Therefore, the hemostatic effect can be enhanced. Further, for example, it is possible to weaken the pressing force on the puncture site t1 by decreasing the number of the pressing portions 340, and increase the pressing force on the puncture site t1 by increasing the number of the pressing portions 340. Is also possible.

  In addition, the shape, structure, etc. of the pressing part that is changed or attached by the pressing part changing unit 380 are not particularly limited. For example, as shown in FIG. 8, the pressing portion may have a rounded shape at the tip 441 that applies a pressing force to the puncture site t1, or as shown in FIG. The tip surface of 541 may have a flat shape, or as shown in FIG. 9B, the tip portion 641 may have an elliptical shape, or FIG. As shown, the tip 741 may have a spherical shape. In the hemostatic device including the pressing unit changing unit 380, for example, a desired pressing protocol can be realized by using any combination of the illustrated pressing units. In addition, each illustrated press part may be, for example, a solid type in which the pressing force is maintained constant, or may be capable of changing a pressing range described later. Further, the pressing portion changing unit 380 can be provided in any of the hemostatic devices 100 shown in the first embodiment and the hemostatic device 200 shown in the second embodiment.

<Modified example of pressing part>
10 and 11 show a modification of the pressing portion. For example, the pressing portion can be configured by an elastic member capable of changing a pressing range for applying a pressing force to the patient's hand H. For example, silicon or the like can be used as the elastic member.

  In procedures in the palm arteries of the patient's hand H (radial artery around the snuff box running on the back of the hand Hb side, distal radial artery running on the fingertip side from the snuff box, etc.), the puncture site t1 Since the depth of the blood vessel B is different and the surgical method is not established, it is conceivable that the puncture angle varies depending on the operator. Therefore, in order to perform hemostasis more reliably, it is preferable to hold both the puncture point on the skin and the puncture point on the blood vessel when performing hemostasis.

  For example, as shown in FIG. 10 (A), when the blood vessel is punctured at a shallow angle and the blood vessel is at a deep position, hemostasis is performed over a wide range by a pressing portion 840 whose pressing range can be changed. On the other hand, for example, as shown in FIG. 10B, when the blood vessel is punctured at a deep angle and the blood vessel is in a shallow position, hemostasis is performed in a narrow range by a pressing portion 840 that can change the pressing range. By using the pressing portion 840 that can change the pressing range for applying the pressing force, for example, when it is difficult to visually confirm the puncture point in the blood vessel, the degree of bleeding is confirmed by narrowing the pressing range. As a result, the puncture site t1 can be suitably stopped without changing the pressing portion.

  Further, in the procedure in the palm arteries of the patient's hand H, the puncture site t1 is formed in a portion of the hand H having a three-dimensional shape, and the puncture site t1 is formed in the movable portion of the hand H. If the range to which is applied is excessively wide, the pressing portion may be displaced from the puncture site t1. In order to prevent such displacement, for example, a pressing portion 940 having a plurality of nested cup members as shown in FIGS. 11A and 11B can be used. . When the pressing force applied to the puncture site t1 increases, the pressing unit 940 contracts by overlapping the nested cups and presses a wide range. Further, when the pressing force applied to the puncture site t1 is reduced, the pressing portion 940 presses a narrow range by releasing the overlapping of the nested cups and extending. As described above, the pressing unit 940 can appropriately stop hemostasis of the puncture site t1 by changing the pressing range by changing the pressing force applied to the puncture site t1.

  The adjustment of the pressing force of the pressing portion according to each modification shown in FIGS. 10 and 11 is performed, for example, by adjusting the pressing force (biasing force) applied by the pressing member 270 (see FIG. 4). be able to.

<Other variations>
The structure around the puncture site t1 in the palm arteries of the patient's hand H has a complicated shape with tendons and bones gathered. Therefore, it is conceivable that the optimum shape for hemostasis differs among patients. Thus, for example, before starting the procedure, take a mold with an optimal shape (state where blood vessels are close to the surface) at the time of hemostasis, and use a device (for example, a pressing unit) that uses that mold at the time of hemostasis It is preferable to stop bleeding at an optimal position and shape. For example, the mold can be taken on either the back side or the palm side, or both. As an example of the use of such a device, for example, the following procedure can be given. (1) Find an optimal joint of the hand H at the time of hemostasis while applying echo to the patient's hand H before the procedure. (2) Next, for example, the mold softened by heat is pressed against the hand H to take the mold. (3) During the procedure, the mold is cured by cooling. (4) At the time of hemostasis, a mold is attached to the hemostasis device and hemostasis is performed.
