Technical Field

[0001] The utility model belongs to the field of medical auxiliary equipment, and in particular relates to an upper arm infusion port surgical incision fixator. Background Art

[0002] An infusion port is a specialized infusion device inserted into the body to reduce vascular irritation caused by medication. It can be used for patients requiring long-term, repeated intravenous medications; those undergoing blood draws, transfusions, and nutritional supplements; those receiving boluses of contrast agents; and those taking chemotherapy drugs for extended periods. It offers numerous advantages, including the lack of exposed tubing, minimal impact on daily life; a lower risk of infection; and the ability to be used repeatedly over the long term.

[0003] The implantation of an upper arm infusion port is usually done by giving the patient local anesthesia. The doctor then makes a small incision (usually 2.5cm to 3cm in length) on the inner side of the mid-upper arm to insert the catheter, create a pouch, connect the catheter to the injection port, and then implant the injection port under the skin. However, when making the surgical incision, due to the different skin toughness of different patients, some patients have loose or tough skin on their arms, making it difficult for medical staff to control the cutting force. They may mistakenly cut the patient's skin too long or not long enough, requiring multiple cuts, resulting in uneven incisions, poor postoperative wound healing, and the risk of excessive scarring.

[0004] Therefore, there is an urgent need for an upper arm infusion port surgical incision fixator, which can effectively fix the skin around the incision, guide the cutting direction of the scalpel, limit the cutting length of the scalpel, avoid repeated cutting, ensure a smooth incision, and improve surgical efficiency.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0024] refer to Figure 1 、 Figure 2 The present invention provides an upper arm infusion port surgical incision fixator, comprising a fixator body, an incision fixator frame 1, and an incision guide slot 2 extending vertically through the incision fixator frame 1. The incision fixator frame 1 is made of plastic, specifically rigid polyvinyl chloride, with a thickness between 3 and 6 mm and a hardness of Shore D of 80 or higher. This high hardness makes it less susceptible to bending and deformation, allowing for stable contact with the skin and effective guidance of the incision.

[0025] Furthermore, the lower surface of the incision fixing frame 1 is provided with a skin-adhering layer 7. The skin-adhering layer 7 is made of silicone gel, and its surface is absorbent. When attached to the skin, it has a certain adsorption and fixing effect. The materials of the incision fixing frame 1 and the skin-adhering layer 7 both meet medical standards. The skin is constrained by the skin-adhering layer 7 and the incision fixing frame 1 above, and will not deform when the scalpel is incised. This facilitates the operation of medical personnel, and thus makes the incision smooth and beautiful, which is conducive to the healing of postoperative wounds. At the same time, in order to allow the scalpel to enter the incision guide groove 2 more smoothly, this embodiment has an opening at one end of the incision guide groove 2, so that incision can be made directly from the opening during use. Furthermore, since the incision fixing frame 1 is made of plastic and has low cutting resistance, in order to prevent the scalpel from cutting through the incision guide groove 2 due to poor control of the force during cutting, thereby affecting the judgment of the cutting length, this embodiment provides a limit block 3 at the other end of the incision guide groove 2. The material of the limit block 3 is hard rubber, and the scalpel can stop when it cuts to the limit block 3. The rubber material can reduce the collision damage of the scalpel blade, thereby protecting the scalpel.

[0026] Furthermore, in order to facilitate medical personnel to know the incision length in real time, a scale line 4 is provided on one side of the incision guide groove 2. The scale line 4 has a range of 2.5 cm to 3 cm. In this embodiment, the scale line 4 has a range of 3 cm, and the scale corresponding to the maximum measurement value on the scale line 4 is located just on the side of the limit block 3 close to the opening direction of the incision guide groove 2, indicating that when the scalpel cuts to the limit block 3, the maximum incision length is 3 cm. Furthermore, in order to prevent the scalpel from slipping when pressed, a pressing portion 5 is provided on the upper surface of the incision fixing frame 1 in this embodiment. The pressing portion 5 is provided with an anti-slip device, and the anti-slip device includes a plurality of anti-slip strips 6 arranged at intervals.

[0027] When using it, the incision guide groove 2 on the incision fixing frame 1 is placed at the patient's skin where the incision is to be made. With one hand, the pressing portion 5 is pressed, and with the other hand, a scalpel is inserted through the opening of the incision guide groove 2. The patient's skin is then incised along the incision guide groove 2. A single incision can achieve the desired length, avoiding the uneven wound caused by multiple incisions. As an auxiliary instrument during surgery, it can guide the incision direction of the scalpel and limit the incision length of the scalpel, greatly improving surgical efficiency.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
