Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a forearm fixing device in coronary intervention surgery. Background Art

[0002] In percutaneous coronary intervention (PCI), radial artery and distal radial artery puncture is currently the most commonly used surgical approach in clinical practice. Because radial artery and distal radial artery puncture causes little damage, does not require bed rest after surgery, and patients are highly comfortable, successful puncture is the first step in all interventional operations, and is a prerequisite for the next step of catheterization, guidewire, dilation, and other operations. Failure of radial artery or distal radial artery puncture means that the patient may suffer greater trauma and pain. Therefore, under the premise of radial artery or distal radial artery puncture, in order to ensure the success rate of puncture, it is often necessary to fully expose the strongest pulsation part of the radial artery or distal radial artery, and often requires the patient's palm and forearm to be in an overextended position, which not only affects the patient's comfort, but also makes it difficult for the patient to persist when the operation time is long. Therefore, this brings additional challenges. Guidewires, catheters, sheaths and other operating materials may be displaced due to the patient's difficulty in persisting, causing additional risks. Although a series of measures such as wrapping the palm and forearm with tape and raising the wrist have been taken in clinical practice, these methods have limitations. Not only does it affect the operation, but the effect of wrapping the gauze or raising the wrist is limited. The patient's forearm is easy to slip and difficult to maintain stability for a long time, which not only increases the difficulty of puncture, but also may cause other serious complications during the operation. Therefore, the existing problem of intraoperative patient forearm fixation needs to be improved urgently to improve the safety and success rate of the operation. Utility Model Content

[0003] The utility model aims to provide a forearm fixing device in coronary intervention surgery, so as to conveniently and firmly fix the forearm of a patient and improve the efficiency and safety of the intervention surgery.

[0004] In order to achieve the above objectives, the technical solution adopted by the utility model is: a forearm fixation device in coronary intervention surgery, including a base, a cover plate, and a palm fixation belt, wherein:

[0005] The base is composed of an arm support seat located on the left and a palm support seat located on the right, the upper surface of the palm support seat is inclined downward from the left end to the right end;

[0006] The cover plate is arranged above the palm support seat, and its right end is fixedly connected to the right end of the palm support seat, and a palm placement area is formed between the cover plate and the palm support seat;

[0007] The rear end of the palm fixing belt is fixedly connected to the middle part of the rear side surface of the palm supporting seat, the front inner side surface of the palm fixing belt is fixedly provided with a Velcro hook surface, and the middle part of the front side surface of the palm supporting seat is fixedly provided with a Velcro fleece surface.

[0008] The method of using the utility model is:

[0009] During interventional surgery, after fully disinfecting the patient's forearm, the intervention site can be fixed, that is, the patient's forearm is placed on the arm support, the palm is inserted into the palm placement area between the cover and the palm support, the back of the palm is attached to the upper surface of the palm support, and the palm fixing belt passes through the palm placement area and is attached to the front side of the palm support with Velcro to fix the palm.

[0010] The beneficial effects of the utility model are:

[0011] This device ensures that the forearm and palm can remain in a stable fixed state during the entire intervention process, ensuring the cooperation of the operation;

[0012] Due to the use of Velcro, the sticking position of the palm fixing strap can be adjusted to adjust the tightness to a certain extent;

[0013] With the help of the downward slope of the palm support seat, the forearm and palm are stably in the hyperextension position, which can fully expose the puncture site, help doctors perform arterial puncture operations, and help improve surgical efficiency;

[0014] When the device is used in surgery, different puncture sites on the left and right sides can be easily switched, thereby ensuring that the puncture side can be freely selected as needed before the operation, and efficient puncture can be performed, helping to improve the efficiency of interventional surgery.

[0015] Furthermore, grooves are provided on both the front and rear sides of the left end of the cover plate.

[0016] In this way, when the patient puts the palm into the palm placement area, the tip of the thumb can be placed in the groove, which not only facilitates the positioning of the palm, but also improves the stability of the palm.

[0017] Furthermore, the specific structure of the cover plate is that the right end thereof extends upward and then bends and extends to the left side in an arc shape.

[0018] Furthermore, the left end of the cover plate is arc-shaped.

[0019] Furthermore, an arc-shaped groove is provided on the upper surface of the arm support seat.

[0020] In this way, the patient's forearm is placed in the arc-shaped groove and is not easy to swing left and right, which can better ensure the stability of the forearm.

[0021] Furthermore, a soft cushion is placed in the arc-shaped groove of the arm support seat.

[0022] Soft cushioning improves patient comfort.

[0023] Furthermore, the palm fixing belt is made of elastic rubber material.

[0024] In this way, it is more convenient to adjust the tightness of the palm.

[0025] Furthermore, a double-sided adhesive tape is adhered to the bottom surface of the base, and a release paper is adhered to the lower surface of the double-sided adhesive tape.

[0026] After tearing off the release paper, you can stick the base to any position on the operating table with double-sided tape to help fix the position of the device. BRIEF DESCRIPTION OF THE DRAWINGS
