[0053] The clamping hemostasis part 1 includes two parts, and the two parts are wrapped around the outside of the hemostasis area, mainly forming a wrapping space for limb hemostasis.
[0054] A more preferred embodiment is that the length and width of the clamping hemostatic part 1 are adjustable, so as to ensure that the instrument can meet the needs of limbs of different sizes; wherein the length adjustment and the width adjustment are both selected by the plug-in adjustment method, and the locking method can be selected by the locking screw.

The distance between the adjusting straight rod 31 and the clamping operation part 21 and the clamping operation part 22 is adjusted, and the hemostatic pressure increases when the distance is increased, and the hemostatic pressure decreases when the distance is decreased; once the position and angle of the adjusting straight rod 31 and the clamping operation part 21 and the clamping operation part 22 are determined, they will no longer change, thereby achieving the purpose of maintaining a certain hemostatic pressure.

A rotating small opening is arranged on the side wall of the notch 33, corresponding to a rotating short rod extending out of the outside of the angle adjustment block 32; the rotating small opening and the rotating short rod are located in the middle position of the notch 33. This arrangement can ensure the maximum selection angle, that is, the most stable setting state. A rounded corner is arranged above the angle adjustment block 32 to avoid damage to the operator during operation. More specifically, the notch 33 is set in the middle of the clamping operation part 2. During operation, the thumb is set at the position of the clamping operation part 22, and the index finger and the middle finger are respectively set on both sides of the notch 33 of the clamping operation part 1 21; this method makes it convenient to operate, and the extended adjustment straight rod 31 can be extended from the gap between the index finger and the middle finger, and the operation will not be interfered with by the rotatable adjustment structure.

A more preferred embodiment is that an anti-slipping portion is provided at the second end of the adjusting straight rod 31 to prevent the adjusting straight rod 31 from slipping out of the adjusting hole 321. The anti-slipping structure may be an extension of the threaded segment, or when the threaded segment does not extend to the second end of the adjusting straight rod 31, an anti-slipping ring 313 larger than the adjusting hole 321 is provided. By arranging the adjusting straight rod 31 in sections, the adjusting straight rod 31 can be rotated to a portion without the threaded segment during the clamping operation, so that the anti-slipping structure of the adjusting straight rod 31 can easily contact the angle adjustment block 32, reducing the portion protruding above the angle adjustment block 32, thereby reducing the difficulty of the clamping operation.
[0063] A more specific implementation is as follows: the instrument further includes a positioning structure, which is arranged on the clamping operation part 22, and is used to maintain the adjustment straight rod 31 in the position of the clamping operation part 2 during adjustment and ensure the angle adjustment of the second end of the adjustment straight rod 31 and the contact position of the clamping operation part 22. The specific implementation is that the positioning structure is a containing structure arranged on the clamping operation part 22; the second end of the adjustment straight rod 31 is provided with an insertion head that enters the containing structure to achieve position limitation but ensures angle change. Specifically, the containing structure is a through hole 341 that penetrates the clamping operation part 22, and the insertion head is a conical head 342 that extends into the through hole 341; different edge positions of the conical head 342 contact the outer edge position of the through hole 341, and this arrangement can ensure the angle change of the position of the adjustment straight rod 31 and the through hole 341. The through hole 341 is a cylindrical hole, and the angle between the axis of the conical head 342 and the axis of the cylindrical hole changes during the pressure adjustment process. In a more preferred embodiment, the maximum diameter of the conical head 342 is consistent with the through hole 341, and the length of the conical head 342 is greater than or equal to the diameter of the through hole 341. The above arrangement can ensure that the through hole 341 provides an effective adjustment space for the angle change of the conical head 342 in the through hole 341, and the shorter the distance of the conical head 342 extending into the through hole 341, the larger the adjustable space.
[0064] Alternatively, the containing structure is a spherical socket, and the insertion head is a spherical head. A more preferred embodiment is that the spherical socket and the spherical head are provided with corresponding guide protrusions and guide grooves, which are used to guide the ball head to rotate in a plane after being combined with the socket. The above plane is parallel to the rotation plane of the clamping operation part 2 to ensure the stability of the adjustment. The setting of the spherical socket and the spherical head and the corresponding guide protrusions and guide grooves can ensure the safety and effectiveness during adjustment. Furthermore, an anti-slip protrusion is provided on the spherical socket.
[0065] Alternatively, an angle adjustment block 32 is also provided on the second clamping operation part 22, and the accommodation structure is an adjustment hole 321 provided on the angle adjustment block 32, and the second end of the adjustment straight rod 31 is also provided with an adjustment section 311 accordingly. The angle adjustment block 32 on the second clamping operation part 22 is provided in the same manner as the angle adjustment block 32 on the first clamping operation part 21. This is also a very effective setting method.
[0066] A more preferred embodiment is that, when the hemostatic device is in a static state, two parallel extensions 36 are extended from the clamping operation part 1 21 and the clamping operation part 2 22, the angle adjustment block 32 is arranged on the extension 36 of the clamping operation part 1 21, and the accommodating structure is arranged on the extension 36 of the clamping operation part 22. This arrangement can effectively improve the convenience of operation.
[0067] The hemostatic balloon is arranged inside the clamping hemostatic part 1. After the pressurized hemostatic action is completed, the hemostatic pressure is adjusted and locked by controlling the distance between the clamping operation part 1 21 and the clamping operation part 2 22 by the rotatable adjustment structure. (The hemostatic balloon is not shown in the figure)
