Field of the Invention The present invention relates to a miniature laparoscopic light source which illuminates the tissues and/or organs with translumination (illuminating by giving light from the back) method during gastrointestinal and other operations.

Background of the Invention

Translumination (illuminating by giving light from the back) technique is used in order to determine the damaged parts or parts with cancer in the tissue and/or organs required to be removed with surgical intervention. Today, Translumination technique can only be used in open surgeries. During an open surgery, tissues and/or organs are examined by bringing them in front of a light source by hands or other instruments. The open surgeries elongating the recovery process cause problems for the patients. Small incisions made on the abdominal wall are used during closed surgeries, and there is no system present in the state of the art which illuminates the tissues or organs from the back.

United States Patent document no US4561430, one of the applications known in the state of the art, discloses a light source used in laparoscopy. The inventive light source has an elongated casing, a power supply contained in the casing, and a light source. The user looks through a sight tube included in an optic system. The said optic system enables the light coming from the light source to be directed towards to object wanted to be examined. However, the said invention is not suitable for illuminating with Translumination technique in the closed surgeries.

Japanese Patent document no JP2000245689, one of the applications known in the state of the art, discloses an auxiliary instrument for endoscope insertion. The said invention has a trocar capable of brightening and an optic fiber. Summary of the Invention

The objective of the present invention is to provide a miniature laparoscopic light source which enables the tissue and/or organs to be illuminated by Translumination technique by entering inside the incisions made on the abdominal wall during closed surgeries whereas does not occupy the incisions used during surgery and made on the abdominal wall.

A further objective of the present invention is to provide a miniature laparoscopic light source which enables the part that is operated to be illuminated with Translumination technique during the whole operation in the closed surgeries.

Another objective of the present invention is to provide a miniature laparoscopic light source which does not give thermal energy to the tissue and/or organs while illuminating the tissue and/or organs.

Detailed Description of the Invention

"A miniature laparoscopic light source" developed to fulfill the objective of the present invention is illustrated in the accompanying figure wherein,

Figure 1 is the perspective view of the miniature laparoscopic light source.

The components in the figures are numbered individually, where the numbers refer to the following:

1. Miniature Laparoscopic Light Source

2. Body

3. On/Off switch

4. Light Source 5. Battery casing

6. Ring

K. Coating A miniature laparoscopic light source (1), which enables the tissues and/or organs to be illuminated with translumination technique in closed surgeries such as gastrointestinal operations, comprising

- a body (2),

an on/off switch (3) which enables the miniature laparoscopic light source (1) to be operated and turned off,

a light source (4) which gives light to the operation area,

at least one battery casing (5) wherein the power supply (such as cell, battery) which will provide energy required for the light source (4) is placed, and

- at least one ring (6) to which a string is tied in order to be pulled away after the surgery is completed.

The body (2) is a hollow cylindrical structure and contains the other components which constitute the inventive miniature 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 material which does not harm the tissue and/or the organs. In the preferred embodiment of the invention, the coating (K) material is polypropylene.

The on/off switch (3) enables the inventive miniature laparoscopic light source (1) to be operated and turned off. In the preferred embodiment of the invention, the on/off switch (3) is located in the middle part of the body (2).

The light source (4) is a cold light source which is fixed to both ends of the body (2) with conventional methods and enables the tissue and/or the organs to be illuminated. In the preferred embodiment of the invention, the light source (4) is LED (Light Emitting Diode). In other embodiments of the invention, any kind of cold light source can be used instead of LED.

The battery casing (5) is the part inside the body wherein the power supply providing energy to the light source is located. The connection of the power supply with the on/off switch (3) and the light source (4) is made with conventional methods.

The ring (6) is the extension to which the string (not shown in the figures) is tied in order to pull away the inventive miniature laparoscopic light source (1) from the abdominal cavity and remove via the trocar, and which is comprised of the coating (K) used on the body. In the preferred embodiment of the invention, the ring (6) is placed at the end part of one of the light sources. The inventive miniature laparoscopic light source (1) enables the tissue and/or organs to be illuminated with translumination method in closed surgeries. The miniature laparoscopic light source (1), which is used during closed surgeries and transferred into the abdominal cavity from the incisions present on the abdominal wall through the trocars on the said incisions, is placed behind the organ and/or tissue to be operated. The miniature laparoscopic light source (1) placed behind the tissue and/or organ enables the tissue and/or the organs to be illuminated with translumination technique via the light it emits. The miniature laparoscopic light source (1) is removed from the abdominal cavity by being pulled via the string tied onto the ring (6) after the operation is completed. The inventive miniature laparoscopic light source (1) is used for single use and disposed after the operation or can be recycled.

It is possible to develop various embodiments of the inventive "miniature laparoscopic light source" (1). The invention can not be limited to the examples described herein and it is essentially as defined in the claims.
