Description

1 TARIFF DYNAMIC GUIDING AND SUPPORT SYSTEM 5 FOR MICROSURGICAL INSTRUMENTS Technical Area This invention is particularly useful for surgeons working in deep and narrow spaces (neurosurgery, ophthalmology, etc.). the stability of the hand instruments used (especially surgical aspirators and dissectors) 10 Developed to enhance and dampen natural micro-tremors in the hand, with a dynamic guidance and support system that can be attached to an operating table or fixed rings. It is related. Previous Technique Today, the hand used by surgeons (neurosurgery, ophthalmology, etc.) during surgery. surgical or medical instruments (especially surgical aspirators and dissectors) 20 for cutting, holding, separating, joining tissues or visualizing the area during the procedure (Medical instruments and auxiliary equipment used) can be moved stably. This is of great importance, especially in procedures such as brain surgery, where even a slight deviation can affect the patient. This can lead to serious health problems. During the operation, the surgeon... movement stable depending on the length of the surgical instrument / tool ​​being used It becomes more difficult to control, and stable movement requires a high degree of attention and experience. 25 Despite high precision and experience, it is possible to dampen natural micro-tremors in the hand. Because this is not possible, the desired stability cannot be fully achieved. The known characteristics of the technique... in this case, it completely clamps and locks the instrument, rendering it immobile (rigid clamping). Although mechanisms exist, these mechanisms depend on the surgeon's actions in the field during the procedure. It interferes with tactile feedback. US6568300B2, US8498744B2 30 When inventions like these are examined, the fixation of the instrument / tool ​​that will be used in the process becomes crucial. It will be seen that it is aimed at facilitating the surgeon's movements during the operation. Various hand and arm supports as in inventions US4018217A and US8745790B1. There are mechanisms, but these mechanisms also enable hand instruments / tools. 2 stable movement and damping of natural micro-tremors in the hand are precisely the key. It is not available. Purpose of the Invention The purpose of this invention is to create a handpiece used by surgeons (neurosurgery, ophthalmology, etc.). instruments / tools (especially surgical aspirators and dissectors) during surgery The aim is to increase stability and dampen the natural micro-tremors in the hand. 10 The purpose of this invention is to improve the stability of hand instruments / tools during intervention / surgery. while ensuring the surgeon's tactile sensation (tactile feedback) in the field. It is about providing opportunities. The purpose of this invention is to allow the surgeon to place the instrument on the bed at any time, laterally (to the right-15 (to the left) it can eliminate vibrations, precisely adjust the depth with linear movement, and When he's finished, he lifts the instrument up and leaves the field without loosening any clips / screws. The goal is to ensure that it can be removed quickly and easily. The product subject to the invention is shown in the attached figures; 20 Figure 1 - Schematic view of the invention in its field of application. Figure 2 - Appearance of detail A in Figure 1. Figure 3 - Schematic view of axial motion. Explanation of References in Figures 1. Support arm 25 2. Joint 3. Bed 3.1. Transition gap 3.2. Contact layer 3 4. Connection mechanism 5. Instrument 6. Left-right movement mechanism Description of the Invention: The product subject to the invention has a semi-rigid structure carrier arm (1), at the end of the carrier arm (1) There is a connecting joint (2) and a bearing (3) connected to the end of the joint (2). Carrier arm 10 (1) thanks to the connecting mechanism (4) attached to the bottom of the operating table or It can be fixed to a carrier brought near the operating table. The carrier arm (1) is semi-rigid. Because of this property, when force is applied to it, it stretches and changes shape to achieve the desired result. It can be positioned in a certain position, and when the force acting on it is removed, it can be positioned in the same position again. It remains in the desired position. Therefore, the bed (3) which is connected to the carrier arm (1) also remains in the desired position. positioned so that it remains fixed (at the entrance to the surgical field) It is recognized. In the product subject to the invention, the joint (2) allows multi-axis rotation (gimbal (3) the bed is as desired before or during surgery. It helps in its positioning. The bed (3) used in the product subject to the invention is a passage 20 so that the instrument (5) can pass through and lean against it. It contains a gap (3.1). Therefore, although it is produced in the shape of a crescent (half moon), it is not suitable for the purpose. It can also be produced in different ways as appropriate. Again, the product in question is the inside of the bed (3). A contact layer (3.2) can be used on its surface. This contact layer (3.2) has low friction. It can be produced from PTFE (polytetrafluoroethylene) material with a certain coefficient. The invention product has a bed (3) which allows the surgeon to use the instrument (5) 25 (especially surgical aspirators and dissectors, for a surgical or medical procedure) used to cut, hold, separate, join tissues or view the area during surgery medical hand tools and auxiliary equipment) with a freely oscillating length (lever arm) physically The shortening prevents hand tremors from being transmitted to the tip. In the use of the invention... Since the instrument (5) does not need to be locked to the bed (3), the instrument (5) is locked to the bed (3) 30 It can be freely slid back and forth (on the linear axis). Surgical instrument (5) He can eliminate lateral (right-left) tremors by leaning on the bed (3) whenever he wants, It can precisely adjust the depth using linear movement, and when the job is done, there is no... He is able to lift the instrument (5) up and take it off the field without loosening the latch / screw. 4 In the product subject to the invention, rigid left-right movement can be performed if desired. A left-right movement mechanism (6) can be used between the joint (2) and the bearing (3). In this way This allows the surgeon to slide the instrument (5) steadily to the right and left. Hand tremor occurs as a natural consequence of muscle tone and depends on the movement. The more muscles involved, the more severe the condition becomes. Surgical arm braces are most commonly used on the elbow and forearm. or serves as a wrist rest. The closer the surgical instrument support is to the action area. If this happens, the tremor decreases. This is especially important in neurosurgery, particularly in the non-dominant hand. The use of long instruments increases the likelihood of tremor as the depth of the incision increases. This is why... It is important to get support as distally as possible. In some cases, it may come from 10 centimeters further away from the brain itself. Support can be obtained, but this leads to contusion-like conditions in the brain. The invention provides a solution to this problem. 20
