Description

Technical Field

[0001] The present invention relates to the technical field of interventional treatment devices, and specifically, to an adjustable compression device for puncture interventional surgery. Background Art

[0002] In clinical medicine, compression hemostasis is required after puncture operations. The traditional compression hemostasis method mainly relies on manual compression by medical staff, and has the following deficiencies: (1) Inconvenient operation: Medical staff need to maintain a compression posture for a long time, which is easy to cause fatigue and it is difficult to accurately control the compression force. (2) Unstable hemostasis effect: The force and position of manual compression are prone to change, affecting the hemostasis effect and increasing the bleeding risk. (3) Occupying human resources: Manual compression requires special personnel to operate, increasing the workload of medical staff.

[0003] Therefore, the prior art has proposed a compression device to replace manual compression. However, for the existing compression device, sufficient pressure is required when compressing at the puncture point, but it is easy to cause tissue damage at the puncture point and increase the pain of the patient under long-term high pressure. Summary of the Invention

[0004] The present invention provides an adjustable compression device for puncture interventional surgery. The device has a compact structure and is easy to operate. It can achieve precise positioning and intelligent control, effectively improve the hemostasis effect, free the hands of medical staff, be applicable to compression hemostasis after various puncture operations, and can relieve the pain of patients.

[0005] For this purpose, the technical solution adopted by the present invention is as follows: An adjustable compression device for puncture interventional surgery, comprising:

[0006] A clamping mechanism for clamping on the limb at the puncture point of the patient;

[0007] A compression mechanism arranged inside the clamping mechanism for compressing the puncture point;

[0008] An adjusting mechanism arranged on the clamping mechanism for adjusting the compression force of the compression mechanism;

[0009] A pre-compression mechanism arranged on the clamping mechanism for pre-compressing the blood vessel in front of the puncture point;

[0010] A linkage mechanism arranged among the clamping mechanism, the adjusting mechanism and the pre-compression mechanism for driving the pre-compression mechanism to act in a linked manner.

[0011] By adopting the above technical solutions: The clamping mechanism is used to clamp the limb at the puncture point, such as the upper and lower limbs of a patient, to fix the device. The compression mechanism is used to compress the puncture point to achieve hemostasis. The adjustment mechanism is used to adjust the pressure value of the compression mechanism. The pre-compression mechanism can pre-compress the limb above the blood flow before compression, slowing down the blood flow rate. At the same time, in the pre-compressed state, the compression force at the puncture point can be appropriately reduced to reduce the pain of the patient.

[0012] Optionally, the clamping mechanism includes an upper clamping plate and a lower clamping plate. Adjusting belts are provided on both sides between the upper clamping plate and the lower clamping plate. Adjusting buckles are provided on the adjusting belts. The adjustment mechanism, the compression mechanism, and the pre-compression mechanism are all arranged on the upper clamping plate.

[0013] By adopting the above technical solutions: When in use, the device is sleeved at the puncture point. Through the adjusting belt and the adjusting buckle, the upper clamping plate and the lower clamping plate can be fixed, realizing the basic fixation of the device and facilitating the compression of the puncture point.

[0014] Optionally, a threaded hole is provided on the upper clamping plate. The adjustment mechanism includes an adjusting screw rod threadedly connected in the threaded hole. The lower part of the adjusting screw rod is connected to the compression mechanism.

[0015] By adopting the above technical solutions: The adjusting screw rod serves as an active adjustment transmission rod and can be manually turned or externally driven to move up and down on the upper clamping plate, thereby driving the compression mechanism to move up and down, and changing the magnitude of the compression force on the puncture point.

[0016] Optionally, the compression mechanism includes a compression plate rotatably connected to the lower end of the adjusting screw rod through a sliding sleeve. The inner side of the compression plate is arc-shaped.

[0017] By adopting the above technical solutions: When the adjusting screw rod moves downward, it drives the compression plate to move downward through the sliding sleeve, compressing the puncture point. In the reverse process, the compression can be gradually reduced or the compression point can be disengaged, enabling the pressure to be adjusted.

[0018] Optionally, the pre-compression mechanism includes a mounting bracket connected to the side of the upper clamping plate. A torsion shaft is provided on the mounting bracket, and a pre-compression arc-shaped piece is rotatably connected to the torsion shaft.

[0019] By adopting the above technical solutions: The pre-compression arc-shaped piece can be attached to the limb above the puncture point in the blood flow direction under the torsion of the torsion shaft, pre-compressing the blood vessels in front of the puncture point, slowing down and reducing the blood flow rate, thereby facilitating the compression plate to perform appropriate small-pressure puncture hemostasis on the puncture point and appropriately reducing the pain of the patient.

[0020] Optionally, the linkage mechanism includes a driving component disposed on the adjusting screw rod, a pushing component in contact connection with the driving component, and a driven component in contact connection with the pushing component. The driven component is disposed on the pre-pressure arc-shaped piece.

[0021] By adopting the above technical solution: The driving component is used to convert the downward movement of the adjusting screw rod into the horizontal movement of the pushing component, so that the pre-pressure arc-shaped piece can be pressed down by the driven component to pre-compress the limb above the puncture point.

[0022] Optionally, the driving component includes a driving frustum disposed on the adjusting screw rod, with the small-diameter end of the driving frustum facing downward. The pushing component includes a holding block disposed on the lower side of the upper clamping plate. A square hole is provided in the holding block, and a transmission square rod is inserted through the square hole. One end of the transmission square rod is in contact connection with the driving frustum, and a pushing block is provided at the other end. The driven component includes a driven block disposed on the upper side of the pre-pressure arc-shaped piece. A contact inclined surface portion is provided between the pushing block and the driven block.

[0023] By adopting the above technical solution: Turning or driving the adjusting screw rod to rotate in the threaded hole, the adjusting screw rod rotates and moves downward. The transmission square rod can be moved outward by the driving frustum thereon, so that the pushing block on the transmission square rod moves toward the driven block. Due to the existence of the contact inclined surface portion, the pushing block can push the driven block downward, so that the pre-pressure arc-shaped piece can be driven to move downward to press the patient's limb to form a pre-compression.

[0024] Optionally, it further includes an induction control system.

[0025] By adopting the above technical solution: The induction control system can automatically drive the adjusting screw rod to rotate, so that the pressure can be conveniently adjusted, and at the same time, information such as the compression time and compression pressure can be displayed.

[0026] Optionally, the induction control system includes a servo motor and a display control module disposed on the upper clamping plate. The servo motor is connected to the adjusting screw rod. A pressure sensor is further provided in the pressing plate, and the pressure sensor is electrically connected to the display control module.

[0027] By adopting the above technical solution: After the pressure sensor senses the pressure value signal, it can be transmitted to the display control module for display. At the same time, the display control module can control the operation of the servo motor, so as to drive the adjusting screw rod to rotate, facilitating the automatic adjustment of the pressure.

[0028] Optionally, a massage pad and a gripping rod are provided on one side of the lower clamping plate away from the front pre-pressure mechanism.

[0029] By adopting the above technical solution, the comfort of the patient can be improved. Through the grasping rod, the patient can perform small-range grasping training, which is convenient for blood reflux and reduces numbness.

[0030] The working principle and beneficial effects of the present invention are as follows:

[0031] 1. In the present invention, the clamping mechanism is used to clamp the limb at the puncture point, such as the upper and lower limbs of the patient, to fix the device. The compression mechanism is used to compress the puncture point to achieve hemostasis. The adjustment mechanism is used to adjust the pressure value of the compression mechanism, reducing the pain of the patient while achieving hemostasis. The pre-compression mechanism in front can pre-compress the area above the blood flow before compression, slowing down the blood flow rate. At the same time, in the pre-compressed state, the compression force at the puncture point can be appropriately reduced, reducing the pain of the patient.

[0032] 2. The pre-compression arc-shaped piece can fit on the upper limb above the blood flow direction of the puncture point under the torsion of the torsion shaft, pre-compressing the blood vessels in front of the puncture point, which can slow down and reduce the blood flow rate. Thus, it is convenient for the compression plate to perform appropriate small-pressure puncture hemostasis, and can appropriately reduce the pain of the patient.

[0033] 3. After the pressure sensor in the present invention senses the pressure value signal, it can be transmitted to the display control module for display. At the same time, through the display control module, the servo motor can be controlled to act, driving the adjustment screw to rotate, facilitating the automatic adjustment of the pressure.

[0034] 4. By setting the massage pad and the grasping rod, the comfort of the patient can be improved. Through the grasping rod, the patient can perform small-range grasping training, which is convenient for blood reflux and reduces numbness. Brief Description of the Drawings

Specific implementation mode

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0042] As Figures 1-4 As shown, this embodiment proposes an adjustable compression device for puncture intervention surgery, including: a clamping mechanism 100 for clamping on the limb at the puncture point of the patient; a pressing mechanism 200 arranged inside the clamping mechanism 100 for pressing the puncture point; an adjusting mechanism 300 arranged on the clamping mechanism 100 for adjusting the pressing force of the pressing mechanism 200; a pre-pressing mechanism 400 arranged on the clamping mechanism 100 for pre-pressing the blood vessel in front of the puncture point; a linkage mechanism 500 arranged between the clamping mechanism 100, the adjusting mechanism 300 and the pre-pressing mechanism 400 for driving the pre-pressing mechanism to act in a linked manner.

[0043] 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 this device. The pressing mechanism 200 is used to press the puncture point to achieve hemostasis. The adjusting mechanism 300 is used to adjust the pressure value of the pressing mechanism 200, reducing the pain of the patient while achieving hemostasis. The pre-pressing mechanism 400 can pre-press above the blood flow before pressing, making the blood flow rate slower. At the same time, in the pre-pressed state, the pressing force at the puncture point can be appropriately reduced, reducing the pain of the patient.

[0044] The clamping mechanism 100 in this embodiment includes an upper clamping plate 110 and a lower clamping plate 120. The upper clamping plate 110 and the lower clamping plate 120 can be made by injection molding. To facilitate the fixation of this device, adjusting belts 130 are provided on both sides between the upper clamping plate 110 and the lower clamping plate 120. An adjusting buckle 140 is provided on the adjusting belt 130. The adjusting mechanism 300, the pressing mechanism 200, and the pre-pressing mechanism 400 are all arranged on the upper clamping plate 110. When in use, this device is sleeved at the puncture point. By means of the adjusting belt 130 and the adjusting buckle 140, the upper clamping plate 110 and the lower clamping plate 120 can be fixed, realizing the basic fixation of this device and facilitating the compression of the puncture point.

[0045] A threaded hole 320 is provided on the upper clamping plate 110. 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 pressing mechanism 200. The adjusting screw 310 serves as an active adjusting transmission rod and can be manually turned or externally driven to move up and down on the upper clamping plate 110, thereby driving the pressing mechanism 200 to move up and down and changing the magnitude of the pressing force on the puncture point.

[0046] The pressing mechanism 200 in this embodiment includes a pressing plate 220 rotatably connected to the lower end of the adjusting screw 310 through a sliding sleeve 210. The inner side of the pressing plate 220 is arc-shaped, which can adapt to the shape of the patient's limb and closely adhere to the skin near the puncture point. Before use, when the intervention needle is withdrawn at the puncture point, a disinfected gauze layer, etc. needs to be padded at the puncture point. The downward movement of the adjusting screw 310 can drive the pressing plate 220 to move downward through the sliding sleeve 210 to press the puncture point. The opposite process can gradually reduce or release the pressing point, and the pressure can be adjusted.

[0047] The pre-pressing mechanism 400 in this embodiment includes a mounting bracket 410 connected to the side of the upper clamping plate 110. A torsion shaft 420 is provided on the mounting bracket 410. A pre-pressing arc-shaped piece 430 is rotatably connected to the torsion shaft 420. The pre-pressing arc-shaped piece 430 can be attached above the puncture point in the blood flow direction under the torsion of the torsion shaft 420 to pre-press the blood vessels in front of the puncture point, which can slow down and reduce the blood flow speed, thereby facilitating the pressing plate 220 to perform hemostasis with a relatively small pressure on the puncture point and can appropriately relieve the pain of the patient.

[0048] The linkage mechanism 500 in this embodiment includes a driving component arranged on the adjusting screw 310, a pushing component in contact connection with the driving component, and a driven component in contact connection with the pushing component. The driven component is arranged on the pre-pressing arc-shaped piece 430. 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-pressing arc-shaped piece 430 can be pressed down by the driven component to pre-compress the limb above the puncture point.

[0049] Specifically, the driving component includes a driving frustum 510 arranged on the adjusting screw 310, with the small-diameter end of the driving frustum 510 facing downward. The pushing component includes a holding block 520 arranged on the lower side of the upper clamping plate 110. A square hole is provided in the holding block 520, and a transmission square rod 530 is inserted into the square hole. One end of the transmission square rod 530 is in contact connection with the driving frustum 510, and a pushing block 540 is arranged at the other end. The driven component includes a driven block 550 arranged on the upper side of the pre-pressing arc-shaped piece 430. A contact inclined surface part 560 is arranged between the pushing block 540 and the driven block 550.

[0050] When performing compression, turn or drive the adjusting screw 310 to rotate in the threaded hole 320. The adjusting screw 310 rotates and moves downward. The transmission square rod 530 can be moved toward the outer end side through the driving frustum 510 thereon. Thus, the pushing block 540 on the transmission square rod 530 moves toward the driven block 550. Due to the existence of the contact inclined surface part 560, the pushing block 540 can push the driven block 550 downward, so that the pre-pressing arc-shaped piece 430 can be driven to move downward to compress the patient's limb to form pre-compression.

[0051] Of course, compression requires a certain amount of time. Compressing with a relatively large pressure for a long time will cause discomfort to the patient. Generally, the pressure needs to be adjusted every certain period of time. Clinically, the compression process with a relatively large pressure generally lasts for about two hours, and then the compression force can be gradually reduced in stages. However, in the prior art, it is basically manually controlled. In order to achieve automatic control, this embodiment further includes an induction control system 600. Through the induction control system 600, the adjusting screw 310 can be automatically driven to rotate, so that the pressure can be conveniently adjusted, and at the same time, information such as the compression time and the compression pressure can be displayed.

[0052] The induction control system 600 therein includes a servo motor 610 disposed on the upper clamping plate 110 and a display control module 620. The servo motor 610 is connected to the adjusting screw 310. It further includes a pressure sensor 630 disposed in the pressing plate 220, and 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 servo motor 610 can be controlled to act through the display control module 620, so as to drive the adjusting screw 310 to rotate, facilitating the automatic adjustment of the pressure. For example, after the initial large pressure is controlled and 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, relatively lifting the pressing plate 220 to reduce the pressing force, and the pressing force can also be controlled to decrease periodically, eliminating manual operation.

[0053] In order to reduce the pain of the patient, a massage pad 700 and a grasping rod 800 are provided on the side of the lower clamping plate 120 away from the preloading mechanism 400 in this embodiment, which can improve the comfort of the patient. Through the grasping rod 800, the patient can perform a small-range grasping training, facilitating blood return and reducing numbness.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
