AI Technical Summary

Technical Problem

During endoscopic thoracic surgeries, the straight axis of endoscopic staples can cause the tip to catch on structures below the vessel or bronchus, risking damage to neighboring tissues, especially in procedures like segmentectomy and lobectomy where vessels and bronchi are small and closely located.

Method used

A curved tip holder is designed for endoscopic lung surgeries, featuring a handle, a body with an asymmetric section, and a cylindrical, blunt curved tip. This holder suspends the vessel or bronchus over adjacent structures, creating space for staple placement and reducing the risk of injury.

Benefits of technology

The curved tip holder significantly reduces the risk of injury and bleeding by providing a clear path for staple placement, ensuring that the staple can close the vessel or bronchus without damaging surrounding tissues.

Description

[0001] CURVED TIP HOLDER USED FOR STAPLING IN ENDOSCOPIC THORACIC SURGERIES

[0002] TECHNICAL FIELD

[0003] The invention relates to a curved tip holder that facilitates the dissection of vascular and / or airway (bronchial) structures and the placement of a staple in endoscopic thoracic surgeries (video thoracoscopy).

[0004] PRIOR ART

[0005] Endoscopic thoracic surgeries (videothoracoscopic surgeries - VATS) are procedures that allow lung surgery to be performed through skin incisions of only a few centimeters, contributing to less pain, fewer complications, and faster recovery for patients compared to open surgery. Therefore, they are widely accepted in thoracic surgery. However, these closed surgeries require the use of automatic closing and cutting tools known as endoscopic staples. The staple provides safe and quick closure and cutting for both vascular and bronchial structures. For the staple to completely close the vessel or bronchus, it is necessary for these structures to be completely freed and for there to be enough space between them and adjacent tissues to accommodate the staple. This prevents the risk of injuring neighboring tissues. However, when placing the staple, its straight axis can cause the tip to catch on structures below the vessel or bronchus, creating a risk of damage.

[0006] For endoscopic surgeries, many endoscopic hand tools are produced with curved tips. Although some staples are made with curved tips, they are single-use and high-cost. More commonly used staples are made with straight tips, necessitating the use of a second hand tool during placement.

[0007] BRIEF DESCRIPTION OF THE INVENTION

[0008] The invention relates to a curved tip holder used in endoscopic lung surgeries (videothoracoscopic) such as segmentectomy, lobectomy, and / or pneumonectomy, during the stapling of vascular and bronchial branches of those structures. This holder facilitates the easier placement of the staple by creating a space behind the vessel or bronchus, ensuring it stays away from the stapler. This significantly reduces the risk of injury and bleeding, especially in segmentectomy and lobectomy, where the diameters of the vessels and bronchi are very small and located very close to other structures within the parenchyma.

[0017] DETAILED DESCRIPTION OF THE INVENTION

[0018] The invention is characterized by its components: a handle (1), a body (2) containing the body section (2.1 ), and a curved tip (3).

[0019] The handle (1 ), being at least 5 cm in size according to the grasp of the hand, provides ease of movement. The body (2) of our invention is at least 15 cm (optimum: 35 cm) in length, allowing easy access to every area within the thoracic cavity. The single-piece body (2) ends with a curved tip (3) that has a minimum bend of 10 degrees (optimum: 30 degrees) and a length of at least 0.5 mm (optimum: 1 cm). The curved tip (3) is used for both freeing and suspending the vessel and / or bronchus, separating adjacent tissues. Moreover, the curved tip (3) is cylindrical and blunt for the protection of surrounding tissues, unlike the asymmetric structure in the body section (2.1 ), and has the same thickness as the body (at least 3 mm in diameter). The different angle of the curved tip (3) from the body facilitates surgical dissection and retraction in endoscopic lung surgeries.

[0020] The edges of the body (2) are blunt to prevent damage to the tissue. Additionally, one edge of the body section (2.1 ) is thicker than the other, creating an asymmetric structure. This design allows the thinner edge to guide the staple, while the thicker edge facilitates tissue retraction.

[0021] The use of the holder during surgery is as follows:

[0022] After the targeted vessel or bronchus is identified and dissected, the holder is placed in such a way as to suspend the vessel or bronchus over the structures behind or below it. This creates a space sufficient for the placement and complete passage of the staple. Since all edges and the curved tip (3) of the holder are blunt, it does not damage surrounding tissues, including the vessel and bronchus structures, thereby eliminating the risk of injury. Additionally, the diameter of the holder [body (2) and curved tip (3)] being at least 3 mm (optimum: 10 mm) allows for its application through the same skin incision or through an additional port, and it is easily used in endoscopic ports.

Claims

CLAIMS1. A holder for facilitating the dissection of vascular and / or bronchial structures and the placement of a staple in closed lung surgeries, characterized by;- A single-piece body (2) at least 15 cm in length, ensuring easy access to every area within the thoracic cavity,- A curved tip (3) used for freeing and suspending the vessel and / or bronchus, separating adjacent tissues, and terminating the body (2) with a minimum bend of 10 degrees and at least 0.5 mm in length.

2. The body (2) as mentioned in claim 1 , characterized by; all edges being blunt, and one edge of the body section (2.1 ) being thicker than the other, forming an asymmetric structure.
