[0002] In clinical medicine, compression hemostasis is required after puncture. Traditional compression hemostasis methods mainly rely on manual compression by medical staff, which has the following shortcomings: (1) Inconvenient operation: medical staff need to maintain the pressing posture for a long time, which is easy to fatigue, and it is difficult to accurately control the pressing force. (2) Unstable hemostasis effect: The strength and position of manual compression are prone to change, which affects the hemostasis effect and increases the risk of bleeding.

However, the existing pressing device needs to use sufficient pressure to press the puncture point, but long-term high pressure is likely to cause tissue damage to the puncture point and increase the patient's pain.

DETAILED DESCRIPTION

[0032] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 4 As shown, this embodiment proposes an adjustable compression device for puncture intervention surgery, including: a clamping mechanism 100, used to clamp on the limb of the patient at the puncture point; a compression mechanism 200, arranged inside the clamping mechanism 100 for compressing the puncture point; an adjustment mechanism 300, arranged on the clamping mechanism 100 for adjusting the compression force of the compression mechanism 200; a pre-preload mechanism 400, arranged on the clamping mechanism 100, for pre-compressing the blood vessel in front of the puncture point; a linkage mechanism 500, arranged between the clamping mechanism 100, the adjustment mechanism 300 and the pre-preload mechanism 400, for linkage-drivenly driving the pre-preload mechanism to operate.

[0034] The basic principle of this embodiment is as follows: the clamping mechanism 100 is used to clamp on the limb at the puncture point, such as the upper and lower limbs of the patient to fix the device, the compression mechanism 200 is used to compress the puncture point to achieve hemostasis, the adjustment mechanism 300 is used to adjust the pressure value of the compression mechanism 200 to reduce the patient's pain while achieving hemostasis, and the pre-precompression mechanism 400 can compress the upper part of the blood flow before compression to slow down the blood flow rate. At the same time, in the pre-compression state, the compression force at the puncture point can be appropriately reduced to reduce the patient's pain.

[0035] The clamping mechanism 100 in this embodiment includes an upper clamping plate 110 and a lower clamping plate 120, wherein the upper clamping plate 110 and the lower clamping plate 120 can be made by injection molding. In order to facilitate the fixing of the device, an adjustment belt 130 is provided on both sides between the upper clamping plate 110 and the lower clamping plate 120, and an adjustment buckle 140 is provided on the adjustment belt 130. The adjustment mechanism 300, the compression mechanism 200 and the front pre-compression mechanism 400 are all arranged on the upper clamping plate 110. When in use, the device is sleeved on the puncture point, and the upper clamping plate 110 and the lower clamping plate 120 can be fixed by the adjustment belt 130 and the adjustment buckle 140, so as to realize the basic fixation of the device and facilitate the compression of the puncture point.

[0036] A threaded hole 320 is provided on the upper clamping plate 110, and the adjusting mechanism 300 includes an adjusting screw 310 threadedly connected in the threaded hole 320. The lower part of the adjusting screw 310 is connected to the compression mechanism 200. The adjusting screw 310 serves as an active adjustment transmission rod and can be manually screwed or externally driven to move up and down on the upper clamping plate 110, thereby driving the compression mechanism 200 to move up and down, and the size of the compression force on the puncture point can be changed.

[0037] The compression mechanism 200 in this embodiment includes a compression plate 220 rotatably connected to the lower end of the adjusting screw 310 through a sliding sleeve 210. The inner side surface of the compression plate 220 is arc-shaped, which can adapt to the shape of the patient's limbs and fit closely to the skin near the puncture point. Before use, when the interventional needle is pulled out, a sterile gauze layer or the like is required to be placed at the puncture point. The downward movement of the adjusting screw 310 can drive the compression plate 220 to move downward through the sliding sleeve 210 to compress the puncture point. The reverse process can gradually reduce or disengage from the pressure point, and the pressure can be adjusted.

[0038] The front pre-stressing mechanism 400 in this embodiment includes a mounting frame 410 connected to the side of the upper clamping plate 110, and a torsion shaft 420 is provided on the mounting frame 410. A pre-stressing arc piece 430 is rotatably connected to the torsion shaft 420. The pre-stressing arc piece 430 can be fitted above the blood flow direction of the puncture point under the torsion of the torsion shaft 420, and pre-compress the blood vessel at the front end of the puncture point, which can slow down and reduce the blood flow speed, thereby facilitating the compression plate 220 to apply appropriate small pressure to the puncture point to stop bleeding, which can appropriately reduce the patient's pain.

[0039] The linkage mechanism 500 in this embodiment includes a driving component arranged on the adjusting screw 310, a pushing component contacting and connected with the driving component, and a driven component contacting and connected with the pushing component, wherein the driven component is arranged on the pre-stressed arc piece 430, and the driving component is used to convert the downward movement of the adjusting screw 310 into the horizontal movement of the pushing component, so that the pre-stressed arc piece 430 can be pressed down by the driven component to pre-compress the limb above the puncture point.

[0040] Specifically, the driving assembly includes a driving vertebral platform 510 arranged on the adjusting screw 310, with the small diameter end of the driving vertebral platform 510 facing downward, the pushing assembly includes a retaining block 520 arranged on the lower side of the upper clamping plate 110, a square hole is provided in the retaining block 520, a transmission square rod 530 is passed through the square hole, one end of the transmission square rod 530 is in contact and connected with the driving vertebral platform 510, and the other end is provided with a pushing block 540, the driven assembly includes a driven block 550 arranged on the upper side of the pre-stressed arc piece 430, and a contact inclined portion 560 is provided between the pushing block 540 and the driven block 550.

[0041] When compression is performed, the adjusting screw 310 is twisted or driven to rotate in the threaded hole 320, and the adjusting screw 310 rotates and moves downward. The driving vertebral platform 510 thereon can make the transmission square rod 530 move toward the outer end side, so that the pushing block 540 on the transmission square rod 530 moves toward the passive block 550. Due to the existence of the contact inclined surface 560, the pushing block 540 can push the passive block 550 downward, thereby driving the pre-compression arc piece 430 to move downward to compress the patient's limb to form pre-compression.

[0042] Of course, compression requires a certain amount of time. Long-term high-pressure compression will cause discomfort to the patient. Generally, the pressure needs to be adjusted every certain period of time. Clinically, the high-pressure compression process usually takes about two hours, after which the compression force can be reduced in stages. However, the prior art is basically manually controlled. In order to achieve automatic control, the present embodiment also includes a sensing control system 600. The sensing control system 600 can automatically drive the adjustment screw 310 to rotate, thereby facilitating the adjustment of the pressure, and can display information such as the compression time and compression pressure.

[0043] The sensing control system 600 includes a servo motor 610 and a display control module 620 disposed on the upper clamping plate 110, wherein the servo motor 610 is connected to the adjusting screw 310, and also includes a pressure sensor 630 disposed in the compression plate 220, wherein the pressure sensor 630 is electrically connected to the display control module 620. After the pressure sensor 630 senses the pressure value signal, it can be transmitted to the display control module 620 for display. At the same time, the display control module 620 can control the servo motor 610 to move, thereby driving the adjusting screw 310 to rotate, so as to facilitate automatic adjustment of the pressure. For example, after the initial large pressure control is maintained for 2 hours, the display control module 620 can drive the servo motor 610 to drive the adjusting screw 310 to rotate in the reverse direction, thereby relatively lifting the compression plate 220 to reduce the compressive force, and can also control and reduce the compressive force in stages, eliminating manual operation.

[0044] In order to reduce the patient's pain, the lower clamping plate 120 in this embodiment is provided with a massage pad 700 and a gripping rod 800 on the side away from the front preload mechanism 400, which can improve the patient's comfort. The gripping rod 800 can enable the patient to perform small-range gripping training to facilitate blood circulation and reduce numbness.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
