Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a handheld back-mounted clothes-tearing scissors. Background Technology

[0002] In emergency trauma care, treating severely injured and comatose patients during autumn and winter presents numerous challenges. Heavy clothing at this time severely restricts the exposure of critical body parts, thus interfering with the treatment process. For example, the rapid and standardized application of a neck brace is limited by clothing, affecting neck safety; the timely establishment of intravenous access is delayed, jeopardizing the maintenance of vital signs; and the initial trauma assessment is also difficult to conduct comprehensively and accurately due to clothing obstruction, leading to assessment biases and impacting the development of subsequent treatment plans.

[0003] Currently, ordinary tailor's scissors and roller shears are commonly used in emergency trauma rooms to remove clothing from patients. Ordinary tailor's scissors have a limited operating direction, making it impossible to remove clothing from the back of supine patients who cannot be moved, thus limiting the examination and treatment of back trauma. Furthermore, their sharp tips can easily cause secondary injury. While roller shears are efficient at removing clothing, they are expensive, burdening departments with limited medical resources. Some roller shears also suffer from rapid gear wear and poor durability; equipment failure in critical moments could delay treatment, and their limited operating direction makes them unsuitable for complex treatment scenarios. Therefore, a handheld back-removing clothing shear is proposed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by employing a three-section operating structure. The extended bending handle assembly between the blade and the grip allows for easy insertion into the gap between the patient's back and the bed surface, enabling the cutting of clothing on the back without moving the patient, thus facilitating the examination and treatment of back injuries. Furthermore, the cutting head features a blunt, closed blade with a rounded, curved end face, effectively preventing secondary injury to the patient during operation and ensuring patient safety compared to ordinary tailor's scissors.

Example

[0033] Please see Figure 1-4 A handheld back-torn scissors assembly includes: a blade assembly consisting of an upper blade and a lower blade hinged together, with their front ends forming a closed cutting head end, the cutting edge of which has a blunt closed structure and an end face with a rounded transition surface; an extended bent handle assembly including a first bent handle connected to the upper blade and a second bent handle connected to the lower blade, the first and second bent handles being zigzag-shaped; and a grip portion including a first grip located at the tail of the first bent handle and a second grip located at the tail of the second bent handle; wherein the extended bent handle assembly is located between the blade assembly and the grip portion, forming a three-section operating structure, allowing the scissors to be inserted into the gap between the patient's back and the bed surface for operation without moving the patient's body.

[0034] The handheld back-mounted ripping scissors of this application are mainly composed of a blade assembly, a cutting head, a grip, and an extended and bent handle assembly. The following is a detailed description of the structure and working principle.

[0035] I. Detailed Structure and Connection Methods of Each Component

[0036] Blade assembly: The blade assembly consists of an upper blade and a lower blade hinged together to ensure that the front ends of the two blades form a closed shearing head. The cutting edge of the shearing head is a blunt closed structure, and the end face is machined into a rounded transition surface to prevent secondary injury to the patient during operation.

[0037] Extended bending tool holder assembly: Machining the first bending shank and the second bending shank to form a zigzag shape, connecting the first bending shank to the upper tool body, and connecting the second bending shank to the lower tool body, with both extending towards the rear of the tool body assembly and forming an operating gap at a suitable angle.

[0038] Grip section: A first grip is installed at the end of the first bending handle, and a second grip is installed at the end of the second bending handle. A pressure-reducing soft ring made of silicone material is embedded in the inner surface of the first and second grips. The pressure-reducing soft ring is engaged with the groove in the grip through an interference flange for easy replacement.

[0039] Rotating assembly and locking element: A rotating assembly is provided between the cutter body assembly and the extended bending shank assembly, rotatably connecting the first rotating rod to the first bending shank so that its end passes through the first bending shank, and rotatably connecting the second rotating rod to the second bending shank so that its end passes through the second bending shank. Positioning pads are installed on the outer periphery of the rotating holes in the first and second bending shanks, and locking elements with an anti-slip groove array are installed at the ends of the first and second rotating rods, ensuring tight contact between the positioning pads and the inner surface of the locking elements.

[0040] Overall assembly: Assemble the above components according to the design structure, so that the extended bending handle assembly is located between the blade body assembly and the grip, forming a three-section operating structure.

[0041] II. Working Principle

[0042] When medical personnel use this hand-held, back-mounted garment shears, they grip the first and second handles. Based on the lever principle, the opening and closing force applied by the hand is transmitted through the first and second handles to the first and second bending handles. Since the first bending handle is connected to the upper blade body and the second bending handle is connected to the lower blade body, and the upper and lower blade bodies are connected by a hinge point, when the first and second bending handles move relative to each other, they cause the upper and lower blade bodies to open and close around the hinge point. The cutting tips at the front ends of the upper and lower blade bodies then perform a cutting action, thereby cutting the patient's clothing. The blunt, closed structure of the cutting tips, with their rounded, curved end faces, effectively avoids scratching the patient's skin when in contact with the body, ensuring operational safety.

[0043] Traditional scissors have a single operating direction, making it difficult to reach the narrow space between the patient's back and the bed. However, this handheld back-cutting scissors features an extended, bent handle assembly that is zigzag-shaped and forms a three-section operating structure with the blade assembly and grip. This unique structure allows the scissors to have a specific bending angle and extension length. In practice, medical staff can easily insert the scissors along the gap between the patient's body and the bed to reach the patient's back. Even if the patient is supine and cannot be moved, medical staff can still hold the first and second handles on the outside of the bed and use the extension and bending of the extended handle assembly to precisely position the cutting tip at the area of ​​the patient's back where clothing needs to be cut, thus successfully completing the back-cutting work and facilitating the examination and treatment of back injuries.

[0044] When faced with clothing cutting needs at different angles, or when adjusting the cutting direction of the scissors in complex medical scenarios, the rotating component of these scissors comes into play. Medical personnel first loosen the locking mechanism. Since the locking mechanism is connected to the ends of the first and second rotating rods, after loosening, the first and second rotating rods are no longer locked. At this point, the blade assembly can rotate around the first and second rotating rods relative to the extended and bent handle assembly. Medical personnel manually adjust the angle of the blade assembly as needed, ensuring the cutting head faces the appropriate direction. After adjustment, the locking mechanism is tightened. The inner surface of the locking mechanism makes close contact with the positioning pad, and through friction and mechanical positioning, the first and second rotating rods are fixed in their respective positions. This allows the blade assembly to stably maintain the adjusted angle, enabling precise cutting operations in different directions and meeting diverse usage needs in complex medical scenarios.

[0045] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
