Description

1 TARIFF MICRO HAZELNUT ASPIRATOR Technical Area 5 This invention utilizes classic dissectors, aspirators, and cottonoids used in microsurgical procedures. It relates to a system that combines its functions at a single atraumatic endpoint. Previous Technique Nowadays, surgeons frequently use dissectors, aspirators, and other devices in microsurgical operations. Surgeons use surgical cotton swabs called "cottonoids". During the operation, the dissector, aspirator, and cottonoid should be removed as needed. 15 Since it requires constant change in the form of being replaced by another one, there is a risk of error. processing times are increasing. The increase in processing times also indicates an urgent need. The inability to perform interventions in a timely manner in procedures requiring intervention, the surgeons' lack of expertise... This leads to disadvantages such as excessive fatigue and attention deficits. Furthermore, modern vacuum cleaners only draw suction from the nozzle. This creates both the need to constantly change position and a feeling of congestion. This can happen. Additionally, there is a risk of hard metal coming into contact with tissues during the procedure. It constitutes. Again, in microscopic blunt dissection, sometimes cottonoid is placed at the tip of the aspirator. The procedures performed require an extra cottonoid check at the tip of the instrument; this check... Because it is difficult to use an aspirator, tissue damage can occur. Purpose of the Invention: 30 The aim of this invention is to improve the performance of classic dissectors, aspirators, and cottonoids used in microsurgery. The goal is to develop a surgical instrument system that combines these functions in a single atraumatic tip. 2 The aim of this invention is to eliminate the need for constant instrument changes in microsurgical operations. The goal is to shorten the operation time by eliminating the obstacle. The purpose of this invention is to prevent contact between hard metal surfaces and delicate tissues during surgery. 5 The aim is to prevent this and minimize the risk of mechanical trauma. The purpose of this invention is to prevent tissues or cottonoid fragments from being removed from the aspirator during aspiration. The goal is to prevent it from escaping into the lumen and clogging the system. The aim of this invention is to enable effective blunt dissection without damaging tissue. 10 The aim of this invention is to enable surgeons to better understand the procedure being performed during an operation. The goal is to enable the patient to focus, thereby increasing the chances of the operation's success. The purpose of this discovery is that it can be used in intracerebral artery and cranial nerve dissection, and also 15 In maneuvers performed with the dominant hand; aspiration without creating contusion in the tissues and It is possible to perform the extraction simultaneously.

There is an atraumatic tip (2) (which can be described as a hybrid tip) connected to the main The housing (1) can be one-piece or two-piece in the form of a shaft (1.1) and shaft housing (1.2). It could be in this form. The product subject to the invention has a cottonoid layer (2.1) on the outermost side of the atraumatic tip (2). 10 The cottonoid layer (2.1) has a soft and biocompatible structure. This allows it to interact with surgical tissues. No hard metal surface that comes into contact is left untouched, especially the brain and cranial nerves. and mechanical trauma that can occur during dissection in delicate structures such as blood vessels The cottonoid layer (2.1) is reduced to a minimum. It also serves as a buffer and drying layer. It is seen. Again, due to its structure, there are small holes or 15 on the cottonoid layer (2.1). It contains pores that allow for aspiration. The cottonoid layer... At the bottom is the metal mesh filter housing (2.2). The metal mesh filter housing (2.2) The end carrier is connected to the body (2.3). This connection is made by opening male connectors into the parts. This can be done through various joining methods, such as tooth section and tooth socket. It depends on the need. The end carrier housing (2.3) and the metal mesh filter housing (2.2) are made of one single piece. 20 It can be produced as and the end carrier body (2.3) is an extension of the metal mesh filter body (2.2). It can be in this form. Thanks to the metal mesh filter (2.2), tissue or during aspiration By preventing cottonoid particles from escaping into the lumen, the risk of blockage is reduced. Male locking end (1.3) end carrier located on the main body or shaft body 25 By inserting into the female connector socket (2.3.1) located in the body (2.3), the main body (1) and It enables the connection of the atraumatic tips (2) to each other. In this way, it is desired The atraumatic tip (2) can be removed and replaced with a new one. This connection It can also be done with different joining methods. At the atraumatic end (2) also blunt dissection It has an integrated micro-ball structure used for this purpose. 30 The invention enables aspiration, blunt dissection, tissue preservation, and cottonoid processing. functions in microsurgical dimensions on a 3–5 French scale in a single atraumatic tip (2) In the current technique, surgeons continuously work between the dissector, aspirator, and cottonoid. While instrument changes are necessary, this system provides uninterrupted operation for 35 hours during operation. 4 It provides research opportunities. The invention is particularly relevant in neurosurgery, skull base surgery, potential for use in microvascular surgery and pediatric microsurgery applications It can also be used in intracerebral artery and cranial nerve dissection. In maneuvers performed with the dominant hand; aspiration without creating contusion in the tissues and It enables the extraction to be performed simultaneously. 5 15 25 35
