Description

Magnetically Maneuvers ble Laparoscopic Camera System 360°
Field of the Invention The present invention relates to a laparoscopic camera system for use in minimally invasive surgery. Specifically, the laparoscopic camera system can be inserted into the abdominal cavity of a surgical patient using only a single umbilical incision for use in laparoscopic surgical procedures, providing more efficient performance of several laparoscopic surgical procedures with the ability of a 360° view of the surgical field while performing the procedures.
Background of the Invention
Laparoscopic Surgery is also called minimally invasive surgery of the abdomen that is performed using a laparoscope. Traditionally, it is being done with either 3 or 4 incisions where trocars are inserted for laparoscopic instruments while the laparoscope is inserted thru the umbilicus. The newer technique involves using Single Incision Laparoscopic Surgery (SILS) where all trocars, instruments, including the laparoscope are inserted thru only one incision. SILS has now become the choice of patients mainly because of its better aesthetic outcome. However, with SILS, there is limited visualization and mobility due to the effect of a restricted space. This leads to increased difficulty of the surgical procedure, lengthier time of completion, and more risks for the patient. Therefore, improvements are needed in the surgical technique, systems, and devices in relation to single incision laparoscopic surgery.
The present invention was designed to address the said difficulties. Features of this invention include the ability of having 360° view of the surgical field while performing the procedure, maneuverability with sustained stability while being attached magnetically to an external handle device, and wireless connectivity while only using a single umbilical incision. With this, there is now enough space for the surgeon to perform procedures better, faster, and safer with fewer scars. Summary of the Invention

In this embodiment, the placement device (40) includes a connector (49) for connecting removably the placement shaft (42) to the handle (41). As shown in FIGURE 4C, the placement device (40) further includes a retrieval shaft (47) connected removably to the connector (49) (FIGURES 4A and 4B), and a pouch component (48) coupled to the retrieval shaft (47) and configured for retrieving the camera device (10) from the patient's abdomen. Referring to FIGURE 6, once the camera device (10) has been positioned to the desired area of the abdominal wall, the handle device (20) located outside the abdomen can be turned on and be magnetically attached to the camera device (10). Once attached, the second knob (46) of the placement device (40) can be operated to release the camera device (10) from the loop component (45). The handle device (20) controls the camera device (10) and its functions wirelessly. Once the surgical procedure is done, the handle device (20) can be turned off to detach the camera device (10), and the pouch component (48) can be used to catch Ihe camera device (10) for removal from the patient's abdomen via the top valve part (311).
