[0002] EDUCATIONAL HAND DISSECTION TOOL

[0003] Technical Field

[0004] The invention relates to a hand dissection tool enabling hyperabduction to the thumb or other finger and hand positions to be provided easily, especially during hand dissection or in surgical operations.

[0005] Prior Art

[0006] Hand dissections are a very detailed region although the area where the application is performed is small. During the dissection of this detailed region or in surgical operations, it is required that especially the thumb be taken into the hyperabduction position by a person. In dissections or operations lasting more than one hour, the process becomes challenging for the person providing the hyperabduction. Furthermore, another deficiency is the insufficiency of resources in cadaver dissections. Anatomists cannot find the opportunity to perform dissection practically on all body regions during their medical or doctorate education; especially in our country, the number of cadavers is insufficient for this. For this reason, after graduating, at the time they are to give dissection training in practical courses, they either enter into a search for resources or take dissection courses privately. These courses are very few and quite expensive courses in our country and in the world.

[0007] Cadaver dissections have been complicated for all anatomists and medical students; the scarcity of cadaver donation in our country is a major problem, and for this reason, the persons who will perform the application have always been professionals, and students and assistants generally have to watch the dissections performed by professionals because in many universities in our country, the number of cadavers is few or none. It is desired that the dissection of cadavers, whose number is small and which are imported at high fees, always be performed by the more experienced ones. However, no matter how good the anatomy and medical education is, if the person performs the application themselves, he / she grasps the structures better and his / her self-confidence increases.

[0008] The utility model document numbered CN216455467U, discloses an animal dissection table for medical experiments.

[0009] The utility model document numbered CN211356054U, discloses a veterinary dissection table having a fixing function.

[0010] When the studies existing in the state of art are examined, the need for the development of a hand dissection tool enabling hyperabduction to the thumb or other finger and hand positions to be provided easily, especially during hand dissection or in surgical operations, has been felt.

[0011] Objectives of the Invention

[0012] The object of this invention is to develop a hand dissection tool enabling hyperabduction to the thumb or other finger and hand positions to be provided easily, especially during hand dissection or in surgical operations.

[0013] Another object of this invention is to develop a hand dissection tool enabling access to the necessary information during the application with the QR code it includes.

[0014] Detailed Description of the Invention

[0015] The hand dissection tool developed to achieve the objecttives of this invention is shown in the attached figures.

[0016] These figures;

[0017] Figure 1: A schematic view of the hand dissection tool subject to the invention.

[0018] Figure 2: A schematic view of the hand dissection tool subject to the invention in an exemplary application.

[0019] Figure 3: A schematic view of the fixing apparatus included in the hand dissection tool subject to the invention. Figure 4: A schematic view of the openable and closable wire mechanism located within the fixing apparatus included in the hand dissection tool subject to the invention.

[0020] The parts located in the figures have been numbered individually, and the equivalents of these numbers are given below.

[0021] 1. Body

[0022] 2. Grid

[0023] 3. Drainage tray

[0024] 4. Fixing apparatus

[0025] 5. QR code

[0026] A hand dissection tool enabling hyperabduction to the thumb or other finger and hand positions to be provided easily, especially during hand dissection or in surgical operations, and comprises:

[0027] A body (1),

[0028] A grid (2) located inside the body (1), being in an integrated structure with the body (1) and having holes thereon,

[0029] A drainage tray (3) capable of being attached into and removed from inside the body (1), positioned under the grid (2), and enabling the waste liquid passing through the grid (2) to be discharged to the outside,

[0030] A fixing apparatus (4) enabling the hand fingers to be fixed by means of the holes on the grid (2) and having balls at its tip portion,

[0031] A QR code (5) located on the body (1) and enabling access to educational information regarding the application directed to the dissection process.

[0032] In the hand dissection tool subject to the invention; the grid (2), which is positioned on the drainage tray (3) found inside the body (1) and on which the hand will be placed, will be produced from 18 / 8 chrome nickel material. The aim with this is to prevent rusting against chemicals such as formaldehyde used in cadaver embalming. The holes found on the grid (2) will ensure that formaldehyde and sterilization liquids or body fluids (blood etc.) in surgical interventions flow and pass easily into the drainage tray (3) and that the operation area is always clean and open. In the same way, the tool subject to the invention becoming inert with body fluids and medical liquids that may be transmitted in operations will be prevented. Since the 18 / 8 chrome nickel material is at the same time a material capable of being sterilized in an autoclave, its use in operations for many years will be possible. The fixing apparatuses (4) manufactured from stainless steel material consist of balls capable of passing inwards while passing through a narrow area at their tips and a body part consisting of transparent insulated steel wire.

[0033] The body part of the fixing apparatus (4) shown in Figure 3 consists of small steel ropes covered with polypropylene (PP), which is a thermoplastic polymer. PP material does not rust and can take shape easily. The reason for the covering of the steel ropes constituting the body part with this material has been considered to prevent the steel ropes from damaging the fingers in long surgical interventions. With the shapeable steel rope and the body covered with PP, fixing the hand and fingers in the desired manner is aimed.

[0034] Polypropylene (PP) is a thermoplastic polymer obtained as a result of the polymerization of a monomer named propylene. This material, having a high melting point, draws attention with its durable structure and properties. Polypropylene is generally a material that stands out by being lightweight, durable, and having chemical resistance. Polypropylene, which can be transparent or opaque, can be produced in various colors and shows resistance against high temperature. Due to these properties, polypropylene is used widely in many sectors, primarily the plastic industry. It has a structure resistant against many chemical substances. Its durability against solvents such as acid and base facilitates its use in chemical processes.

[0035] At both ends of the ropes, there are steel balls similar to the mechanism used in umbrellas, having a spring mechanism inside them. Inside these steel balls, there are steel wires folding inwards while passing through the grid hole which is 5 mm. In this way, the balls, by getting smaller, can narrow down to 4-5 mm while passing through the holes in the grids. To narrow the balls, there is a small pressable part immediately above them capable of controlling the wires inside.

[0036] The fixing of the hand on the grid (2) is provided thanks to the balls contained in the fixing apparatus (4). Every desired finger will be able to be fixed easily to the grid (2) with the portable fixing apparatuses (4) capable of being removed and attached. The balls located at the tip of the fixing apparatus (4) have a structure capable of flexing while passing through inside the grid (2) holes. (Figure 3)

[0037] The balls narrowing and expanding at the tips of the fixing apparatus consist of stainless steel plates; inside the balls, there is a mechanism providing opening and closing from rod-shaped steel wires. The working principle of this mechanism is shown in Figure 4. The balls, expanding with a system just like in the umbrella mechanism, will decrease their width to 4 / 5 mm by narrowing, that is, by the wires folding inwards, while passing through the hole, thus they will pass through the hole comfortably. After passing through the hole, by returning to their old form, that is, to 6 mm, their coming back out of the hole will be prevented. When the pressable part, which will be located immediately above the balls and is connected to the wires, is pushed inwards, the balls will narrow, exit from the hole will be provided again, and the fixing apparatus will be able to be removed easily.

[0038] The holes located in the grid (2) will be able to be adjusted according to various distances according to the largeness and smallness of the hand. In this way, for example, in operations and dissections where thumb hyperabduction is required to be provided and which last especially for hours, by eliminating the situations requiring stabilizing the thumb with human power, the possibility for the person to perform dissection and operation alone will be provided, and the workforce will be reduced. The tool subject to the invention will be useful for surgeons not only in hand dissections but also in hand surgery, that is, in clinics, especially in operations such as carpal tunnel and trigger finger.

[0039] For hand dissection, each stage will be able to be reached with the QR code (5) located on the body (1). An assistant or student, or even high-level professionals who have never performed hand dissection before, will be able to proceed by seeing the structure they will see in the next stage on the application, on the hand which they are able to stabilize alone fearlessly.

[0040] With the QR code (5) located on the tool subject to the invention, when the practitioner or student scans the QR code (5) to their smart phone or tablet, the structures that will appear before them will be explained in a sequential manner with visuals, and it will be ensured that the practitioner proceeds in a professional order regarding each structure opened with previously performed dissection visuals and proceeds knowing the important sensitive structures. Human anatomy is very complex, and dissection requires mastering all these complexities; an application reminding, at the moment of application, in which order the vascular arches and nerves immediately under the cutis (skin) in this region will appear before us will be useful. Thanks to the QR code (5), the lack of information especially in anatomy dissections will be eliminated.

[0041] In the application that will open when the QR code (5) is scanned; for example, general information about the normal (variation-free) hand will be included in the hand Palmar surface dissection. In this way, the application of the anatomical dissections of the cadaver, especially one whose embalming is completed and which is to be dissected for the first time, will be facilitated. Dissection courses are courses whose number is few and which are high-budget; in these courses, especially those planned for a few days, and in countries where cadavers cannot be found like in our country, the chance to perform application is based on watching the practitioner. With the invention, anatomy educators and medical students will be able to reach the information they are curious about with a QR code (5). The structures to be encountered in the application will be explained with both auditory and visual options. The opening order of the structures and fasciae will be shown.
