at least one secondary connection member (10) which is used for fixing the actuating lever (5) to the tube with shape memory (3),
- at least one on/off switch (11) which enables the light source (4) be turned on and off.
The body (2) is a hollow cylindrical structure and contains the other components which constitute the inventive flexible light source (1) therein. In the preferred embodiment of the invention, the body (2) is made of stainless steel. The body (2) is coated with a polymer based material which does not conduct electricity and gives no harm to the tissue and/or organs in order to prevent the tissue and/or organ injuries that can be resulted from any electrical leakage. The tube with shape memory (3) is manufactured from a super elastic material with shape memory one end of which is a hollow tube curled back in a U shape when there is no load thereon. The end of the tube with shape memory (3) which is not U shaped is located such that it can move inside the body (2), and it can be moved back and forth inside the body (2) by means of actuating lever (6). When the actuating lever (6) is pulled backwards the U shaped end of the tube with a shape memory (3) is forced to enter inside the body (2), and it enters inside the body as a flat cylinder by means of the super elastic structure of the tube with shape memory (3). The tube with shape memory (3) which has entered inside the body (2) and the body (2) can be put through the incisions on the abdominal wall to be used during the surgery at this position. While the U shaped end of the tube with shape memory (3) in the body (2), tube with shape memory (3) moves towards the body (2) when the actuating lever (6) is pushed forward. The movement of the tube (3) with shape memory inside the body (2) causes the end of the tube with shape memory (3) to go out of the body (2) and take U shaped form again by means of its shape memory structure. The tube with shape memory (3) is manufactured from a biocompatible material in order that it does not cause any allergic reaction and/or damage on the tissue and/or organs. In the preferred embodiment of the invention, the tube with shape memory (3) is manufactured from nickel-titanium alloy. In another embodiment of the invention, the tube with shape memory (3) is manufactured from any kind of metal or metal alloy. In another embodiment of the invention, the tube with shape memory (3) is manufactured from a polymer material with shape memory.
The light source (4) is at least one cold light source which is fixed to the tube with shape memory (3) via the primary connection member (9) and enables the tissue and/or the organs to be illuminated. In one embodiment of the invention, the light source (4) is fixed to the U shaped end of the tube with shape memory (3) and emits light to the area wanted to be illuminated from U shaped end of the tube with shape memory (3). In the preferred embodiment of the invention, the light source (4) which is fixed to the U shaped end of the tube with shape memory (3) has a cylindrical form and emits light from its entire surface. By this means, even though the end part of the tube with shape memory (3) is not completely formed as U shaped, it illuminates the tissue and/or the organs from their back part. In the said embodiment, there cables inside the tube with shape memory (3) in order to transmit electricity to the light source (4) from an internal or external (cell, battery etc.) source.
In another embodiment of the invention, the light source (4) fixed to the end of the tube with shape memory (3) which is not U shaped. The light emitted from the light source (4) is transmitted to the U shaped end of the tube with shape memory (3) via a preferably cylindrical light transmitter (5) which is fixed inside the tube with shape memory (3) by being located all along the tube with shape memory (3), is flexible, and enables the light to be transferred from one point to another point by guiding the light. The light transmitter (5) enables the light which it receives from its one end to go out from its other end. In the inventive flexible laparoscopic light source (1), the light transmitter (5) enables the light which it receives from the light source (4) that is fixed to the end of the tube with shape memory (3) which is not U shaped to go out of the U shaped end of the tube with shape memory (3). In the preferred embodiment of the invention, the light transmitter (5) is a fiber optic cable. The electric energy required to operate the light source (4) can be received from an integral or external source with known methods. In the preferred embodiment of the invention, the light source (4) is at least one LED (Light Emitting Diode). In other embodiments of the invention, any kind of cold light source can be used instead of LED.
The actuating lever (6) is fixed to the side of the tube with shape memory (3) which is not U shaped via the secondary connection member (10) and enables the tube with shape memory (3) to be moved back and forth inside the body (2). The actuating lever (6) goes out of the body (2) through an opening (7) present on the body (2). In one embodiment of the invention, the actuating lever (6) is a lever going out of the body (2), and when the actuating lever (6) is moved towards the body (2), the U shaped end of the tube with shape memory (3) starts to enter inside the body (2). The holder (8) is the part which is located on the side of the body (2) from which the tube with shape memory (3) does not go out, and which enables the inventive flexible laparoscopic light source (1) to be held.
The inventive flexible laparoscopic light source (1) enables the tissue and/or organs to be illuminated with translumination method in closed surgeries. Upon the actuating lever (6) is pulled backwards, the tube with shape memory (3) to which the actuating lever (6) is connected starts to move backwards inside the body (2). Because of this movement of the tube with shape memory (3) inside the body (2), the U shaped end of the tube with shape memory (3) is forced to enter inside the body (2). The super flexible structure of the tube with shape memory (3) enables the U shaped end to take the form of the body (2) and go inside the body (2). After the tube with shape memory (3) enters inside the body (2) completely, the said invention becomes a straight stick. The flexible laparoscopic light source (1) takes its form to pass through the incisions on the abdominal wall with its current state. The flexible laparoscopic light source (1) inserted through the incisions on the abdominal wall is pushed forward along the tissue and/or organ to be illuminated. After the flexible laparoscopic light source (1) is brought close to the tissue and/or organ to be illuminated, the actuating lever (6) is push forward and the tube with shape memory (3) starts to go out of the body (2). The end part of the tube with shape memory (3) going out takes U shapes which is its original form. The end part of the tube with shape memory (3) becomes U shaped by rotating in a desired amount until the angle between itself and the body (2) will be 0 degree from 180 degree, and the end part of the tube with shape memory (3) is behind the tissue and/or organ. When the flexible laparoscopic light source (1) is in this position, the tissue and/or the organs are illuminated with the translumination method by means of the light emitted from the end part of the tube with shape memory (3).
It is possible to develop various embodiments of the inventive "flexible laparoscopic light source" (1). The invention can not be limited to the examples described herein and it is essentially as defined in the claims.
