Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an intraoperative arm fixation restraint sheet. Background Technology

[0002] With the continuous development of surgical techniques, the effectiveness and safety of the surgical operating space have become crucial factors for surgical success. In various surgical procedures, especially laparoscopic surgery and major surgeries where a large operating space is required, fixing the patient's arm to the side of the body (i.e., "hand wrapping") has become a routine method to expand the surgical operating space. The traditional hand wrapping method usually uses a treatment towel, and the specific operation is as follows: half of the treatment towel is placed under the patient, and the other half is wrapped around the arm and tucked under the surgical mattress.

[0003] However, this traditional method has significant drawbacks:

[0004] Insufficient security: It is difficult to control the tightness of the hand during the bandaging process. If the patient becomes agitated during the operation, the arm may fall off the bed due to the lack of secure restraint, increasing the risk of limb injury.

[0005] Inconvenient blood supply observation: Traditional methods use full-wrap restraint, making it impossible to directly observe blood supply indicators such as skin color and swelling during surgery, making it difficult to meet the needs of fixation and real-time monitoring.

[0006] Furthermore, traditional arm restraint methods typically require two people, resulting in high labor costs, and the treatment towels are for single use, leading to significant consumable costs and infection control pressure. Therefore, we propose a new arm fixation restraint method described in this book. Utility Model Content

[0007] The main purpose of this invention is to propose an intraoperative arm fixation and restraint form that can effectively solve the problems in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: an intraoperative arm fixation and restraint drape, comprising:

[0009] A constraint unit, the constraint unit comprising a body part and an arm constraint part;

[0010] A binding mechanism is provided on the arm restraint section;

[0011] A double-ended zipper, which can wrap around the arm restraint by combining the two chain teeth on the double-ended zipper;

[0012] One of the chain teeth on the double-ended zipper is fixedly connected to the end of the arm restraint part away from the body, while the other is fixedly connected to the other end of the arm restraint part.

[0013] As a further description of the above technical solution, the binding mechanism includes hook-and-loop fasteners and loop fasteners, which are respectively disposed on both sides of the arm restraint part.

[0014] As a further description of the above technical solution, the hook-and-loop fastener is compatible with the loop fastener.

[0015] As a further description of the above technical solution, the chain teeth on the two double-headed zippers are arranged in parallel on the arm restraint part, and their length covers the arm restraint part.

[0016] As a further description of the above technical solution, the body part and the arm restraint part are made of soft silk medical fabric in one piece, and the whole is L-shaped.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This restraint sheet uses a double-fixation structure of double-ended zippers and Velcro, which can flexibly adjust the tightness. The double-ended zippers can be partially opened to observe blood circulation without completely unbinding the restraints, allowing for direct observation of the arm's blood circulation (such as skin color and degree of swelling), making it easier for medical staff to detect abnormalities in a timely manner. The Velcro dynamically adjusts the tightness to prevent the arm from falling off the bed due to being too loose or affecting blood circulation due to being too tight, reducing the risk of limb injury during surgery. The combination of these two features solves the problem that traditional hand wraps cannot simultaneously achieve fixation and observation.

[0019] 2. By fixing the patient's arm to the side of the body, the surgeon's operating range is effectively expanded, which is especially suitable for scenarios with high space requirements, such as laparoscopic surgery and major surgical procedures.

[0020] 3. The main body of this restraint sheet is made of soft, skin-friendly medical fabric, which reduces friction and pressure on the patient's skin and improves comfort during long-term surgery.

[0021] 4. Compared to traditional treatment towels that require two people to operate, this restraint device has a simple structure and can be fixed by a single person, saving labor costs and operation time. It can be repeatedly cleaned and disinfected, reducing the cost of medical consumables and meeting hospital infection control requirements. Attached Figure Description

[0024] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0025] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1 This utility model provides a technical solution: an intraoperative arm fixation restraint sheet, including a restraint sheet body, a binding mechanism and a double-headed zipper 3. The restraint sheet body includes a body part 1 and an arm restraint part 2, and the binding mechanism is set on the arm restraint part 2.

[0028] To further explain, the body part 1 and the arm restraint part 2 are made of soft silk medical fabric in one piece and are L-shaped. The body part 1 is used to fit the patient's torso and the arm restraint part 2 is used to place the patient's arm.

[0029] To further explain, one of the chain teeth on the double-ended zipper 3 is fixedly connected to the end of the arm restraint 2 away from the body 1, while the other is fixedly connected to the other end of the arm restraint 2. The two chain teeth cover the entire length of the arm restraint in parallel. When the two chain teeth are pulled together, the arm restraint can be enclosed. When fully pulled together, it forms a partially openable enclosed cavity, or it can partially enclose and expose the area from the elbow to the elbow. By opening a local area of ​​the double-ended zipper 3 (such as any position between the elbow and the wrist), the skin of the arm can be exposed. It is not necessary to completely release the restraint when observing blood circulation. The length of the zipper can be adjusted according to the observation needs.

[0030] To further explain, by opening a portion of the double-ended zipper, the skin of the arm can be directly exposed, allowing observation of blood circulation without removing restraints, and without affecting the surgical process. It should be noted that the double-ended zipper is a zipper design with two zipper heads, which allows for bidirectional opening, making it more flexible and convenient to use. It is a very mature existing technology, so its structure and working principle will not be described further.

[0031] To further explain, the binding mechanism includes hook-and-loop fasteners 4 and loop fasteners 5. The hook-and-loop fasteners 4 and loop fasteners 5 are compatible with each other and are respectively set on both sides of the arm restraint part 2. By sticking the hook-and-loop fasteners 4 and loop fasteners 5 together, the binding force can be further strengthened, and the tightness can be adjusted according to the thickness of the patient's arm.

[0032] It should be noted that the Rousilen medical fabric is a medical-grade textile material that conforms to the YY / T 0709-2009 standard. It is soft and skin-friendly, antibacterial and breathable, and can be repeatedly sterilized at high temperatures (such as 134℃ high-pressure steam sterilization). The thickness is 0.3-0.5mm, and the tensile strength is ≥15N, which meets the hygiene requirements of the surgical environment.

[0033] It should be noted that this utility model is an intraoperative arm fixation restraint sheet. In use, first, lay the restraint sheet body 1 flat on the operating table, aligning the L-shaped corner with the patient's shoulder. Then, assist the patient to let their arm hang naturally at their side, placing it in the center of the arm restraint part 2. Pull the restraint sheet from the distal end of the body (the end of the arm restraint part 2 furthest from the body) towards the proximal end, ensuring the arm is evenly wrapped. Take care to avoid the zipper pinching the skin. Then, attach the hook-and-loop fasteners 4 and serrated hook-and-loop fasteners 5, adjusting the fastener's adhesive position to ensure the restraint is moderately tight (allowing for the insertion of 1-2 fingers), avoiding excessive tightness that could affect blood circulation. During the surgery, if it is necessary to observe the arm's blood circulation, the zipper can be partially opened to check skin color, temperature, and swelling. After observation, the zipper can be reopened. The double-ended zipper 3 allows for bidirectional opening, providing greater flexibility. Postoperative care: After the surgery, unfasten the hook-and-loop fasteners 4 and serrated hook-and-loop fasteners 5, unzip the double-ended zipper 3, remove the restraint sheet, clean and disinfect according to hospital infection control guidelines, and then air dry for future use. Compared with existing intraoperative arm fixation and restraint methods, this invention has the advantages of stable fixation, easy observation, labor saving, and reusability. It can effectively expand the surgical operating space, improve the safety and comfort of patients during surgery, and is suitable for various surgical procedures that require hand wrapping.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
