Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a medical multifunctional stitch remover. Background Art
[0002] In medical practice, suture removal is an indispensable operation after wound healing. Currently, there are several key issues in the field of suture removal technology:
[0003] (1) Difficulty in identification: During the suture removal process, due to factors such as blood scabs, hair, knotted threads, and insufficient light, doctors often find it difficult to accurately identify and remove the suture knots, which increases the difficulty and risk of the operation;
[0004] (2) Difficulty in removing stitches: The stitches may be too tight or may penetrate into the skin as the wound heals, which may require cutting deep into the wound. This is especially difficult in special areas (such as genitals, face) and in cases of thin stitches.
[0005] (3) Patient pain: Patients, especially children and the elderly, often feel pain during the stitch removal process due to low tolerance. This not only affects the patient experience, but may also have a negative impact on prognosis;
[0006] (4) Risk of secondary trauma: The traditional suture removal process may damage the healed wound and cause secondary trauma, which not only prolongs the patient's recovery time but also increases the risk of complications;
[0007] (5) Insufficient surgical precision: During the operation, the traditional double-blade scissors used to remove the sutures after ligating the blood vessels are not precise enough and can easily damage fragile tissues and blood vessels, thereby increasing the risk of surgery and the possibility of complications.
[0008] At present, the traditional double-blade scissors are still the main tool for stitch removal, but they have obvious shortcomings in the application process:
[0009] (1) Blade design issues: The sharp blades of double-blade scissors are usually blunt, which makes them less sharp when cutting surgical sutures, affecting the efficiency of suture removal.
[0010] (2) Large space occupation: The size of the double-bladed scissors gradually increases from the head to the bottom. When the scissors are inserted deep into the wound to remove the stitches, they will occupy a lot of space due to their large size, which not only increases the pain of the patient, but also easily causes unnecessary tissue damage.
[0011] (3) Operating angle limitation: Since the scissor head is relatively large, the doctor needs to pull the suture head to a larger angle (such as 20-30°) during the operation to ensure that the scissor head can penetrate deep under the suture knot to remove the suture. This operation not only increases the complexity of the operation, but also increases the discomfort of the patient.
[0012] (4) Obstructed vision: During the suture removal process, since the scissors need to penetrate deep into the skin, when the light is insufficient or the vision is obstructed, it is often difficult for the doctor to accurately determine the location of the suture knot to be removed, which increases the difficulty and risk of the operation.
[0013] The closest existing implementation is:
[0014] Although there are some tools that attempt to improve the stitch removal operation, such as changing the shape of the blade, to improve the accuracy and convenience of stitch removal, these tools still fail to completely solve the above problems in practical applications. Therefore, it is necessary to develop a new type of stitch removal tool to overcome the shortcomings of the existing technology and improve the efficiency and safety of stitch removal.
