Description
- Medical professionals employ laparoscopes to perform minimally invasive surgery on a patient's abdominal cavity for diagnostic and treatment purposes. Generally, laparoscopes comprise an instrument configured to pass through a small incision (e.g., in the abdominal wall) and capture images (e.g., video) of areas within a patient. The captured images are normally displayed by large monitors that are positioned proximate to the laparoscopic procedure area (e.g., suspended from the ceiling of the operating room around the operating table). During use, laparoscopes require a myriad of associated equipment, such as power sources, insufflators and so on, which are coupled to the laparoscope via a wiring/tube harness, and so forth. Consequently, laparoscopes are confined to use in dedicated surgical environments, such as a laparoscopic operating room in a hospital.
- A portable laparoscope is disclosed. The portable laparoscope is capable of providing laparoscopic imaging functionality to medical personnel in unconventional environments (e.g., environments other than a dedicated laparoscopic operating room, including environments such as but not necessarily limited to: rural areas, combat zones, and so on). In implementations, the portable laparoscope includes a housing and an elongated tube coupled to the housing. A lighting source and an image capture device are disposed proximate to an end of the elongated tube opposite the housing. The image capture device is configured to capture an image in a viewing area that is illuminated by light provided by the lighting source. The portable laparoscope includes an image display apparatus configured to display the images acquired by the image capture device and/or to transmit the images to a remote display device. The portable laparoscope may be configured to position and hold an insufflator.

- Laparoscopes are generally used to perform minimally invasive surgeries. Laparoscopes employ a variety of detached equipment such as power sources, insufflators, monitors, and so on, which are coupled to the laparoscope via a wiring/tube harness, or the like. For example, laparoscopic equipment is generally connected to a bank of large display screens arranged within a dedicated operating room in order to provide a physician with as large and as detailed a view of a patient's internal organs as possible. Consequently, laparoscopes are very expensive, cumbersome and time consuming to set-up. Thus, laparoscopes have been confined to use in dedicated surgical environments such as a laparoscopic operating room in a hospital, surgical center, or the like.
- In many instances, access to a dedicated surgical environment can be difficult or even impossible, especially when multiple patients must be evaluated and/or treated in a short span of time, such as during a mass casualty event. For example, in the case of an individual who has been subjected to multiple traumatic injuries, there may be a high risk of internal bleeding. Instant triage evaluation of this type of polytrauma patient in the emergency room itself may be difficult, compounded by the fact that diagnosing internal bleeding is very time sensitive in order to provide effective intervention. Although a technique such as Focused Assessment with Sonography for Trauma (FAST) can provide some information, it lacks the ability to fully visualize internal organs in an ambulatory setting, which can help significantly in triaging patients. Further, in the Intensive Care Unit (ICU), diagnosing the onset of internal bleeding or other internal maladies is often complicated because polytraumatic patients are difficult to move or immobile. Thus, in both triage and ICU settings, imaging devices such as Computed Tomography (CT) devices or Magnetic Resonance Imagining (MRI) devices are not feasible solutions, especially when patients are hemodynamically stable and cannot be moved and such equipment is unavailable. With abdominal trauma, the use of CT with contrast may be preferred. As discussed, neither a triage nor an ICU setting lends itself to CT scanning due to a critical condition of patients, lack of patient mobility, and/or time constraints.
- Accordingly, a portable laparoscope is disclosed. In one or more implementations, the portable laparoscope includes a housing and an elongated tube coupled to the housing. The portable laparoscope can be configured to support an insufflator. A lighting source and an image capture device (e.g., a camera) are disposed proximate to an end of the elongated tube opposite the housing. The camera is configured to capture an image in a viewing area that is illuminated by light provided by the lighting source. The portable laparoscope includes an image display apparatus configured to display the images acquired by the camera and/or to transmit the images to a remote display device. In one example, the image display apparatus may comprise a display such as a Liquid Crystal Display (LCD) for displaying captured images and/or captured video of a patient's internals, such as an abdominal cavity, and so forth. In another example, the image display apparatus includes a transmitter disposed in the housing that is configured to transmit images and/or video captured by the camera to a receiver. The receiver is configured to receive the images and/or video for display by a display device communicatively coupled to the receiver.
- The portable laparoscope is capable of providing laparoscopic imaging functionality to medical personnel in unconventional environments (e.g., environments other than a dedicated laparoscopic operating room). Thus, the portable laparoscope may be configured to be used in a variety of environments. For example, the portable laparoscope may be used in remote areas, such as, but not necessarily limited to: military field hospitals or rural areas, in a hospital environment outside of the operating room, or in areas where sophisticated and expensive medical equipment is generally not available. Further, the portable laparoscope may be used in applications other than surgical intervention, such as for surgical evaluation outside of an operating room.
- The portable laparoscope may be used for determining the presence and/or extent of abdominal trauma. This information can then be used to determine an appropriate course of action in treatment, making conservative management of abdominal injury possible by providing information more accurate than that provided by a CT scan. Further, because portable laparoscopy can provide direct visualization of an abdominal cavity, resolution may not significantly influence diagnostic fidelity. However, using a portable laparoscope for abdominal trauma is provided by way of example only and is not meant to be restrictive of the present disclosure. Thus, a portable laparoscope can also be used for ischemic bowel, which may otherwise be difficult to diagnose, and often frustrates radiographic evaluation. Portable laparoscopy at a bedside in the ICU may dramatically ease diagnosis of ischemic bowel with much higher fidelity. In addition to the triage bay and ICU, portable laparoscopy may also be performed in multiple locations outside of the operating room. For example, most medical clinics have a clean space to perform procedures such as lumbar puncture or colonoscopy. Such rooms may also be utilized for laparoscopic evaluation using a portable laparoscope in accordance with the present disclosure. In the following discussion, an example portable laparoscope is described.
- Example Environment
- It will be understood that when an element is referred to as being “connected,” “coupled,” “operatively coupled,” and/or “communicatively coupled” to another element, it can be directly connected or coupled to the other element, or intervening elements may be present. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present. Additionally, like numbers refer to like elements throughout. Reference will now be made in detail to the subject matter disclosed, which is illustrated in the accompanying figures.

FIGS. 1 through 6 illustrate an exampleportable laparoscope 100. As shown, theportable laparoscope 100 includes ahousing 102 and anelongated tube 104 coupled to thehousing 102. The housing can be configured to support aninsufflator 106. Alight source 108 and acamera 110 are disposed proximate to afirst end 112 of theelongated tube 104 coupled to thehousing 102. Thehousing 102 is also configured to holdimage display apparatus 114, that can be configured to display the images acquired by thecamera 110 and/or transmit the images to a remote display device. A power source 116 may also be disposed in thehousing 102 to provide sufficient operational power to the electronic devices disposed in the portable laparoscope 100 (e.g.,light source 108,camera 110,image display apparatus 114, etc.). Thehousing 102 may be fabricated of a medical grade material such as titanium. However, titanium is provided by way of example only, and is not meant to be restrictive of the disclosure. Thus, other materials medical grade materials may be used to construct thehousing 102, theelongated tube 104, and so forth. - The
elongated tube 104 may be configured in a variety of ways. As shown, theelongated tube 104 includes afirst end 112 and asecond end 118. Thefirst end 112 is defined by the end of theelongated tube 104 distal from thehousing 102. In implementations, alight source 108 and acamera 110 are disposed of theelongated tube 104 proximate to thefirst end 112. In some implementations, thelight source 108 and/or thecamera 110 can be disposed of theelongated tube 104 proximate to thesecond end 118. In this type of configuration, lenses, fiber optic cables, and the like can be used to direct light to and from thelight source 108 and/or thecamera 110 along the length of theelongated tube 104. Thelight source 108 and/or thecamera 110 can also be positioned within thehousing 102. A window formed of generally transparent material is disposed at thefirst end 112 to provide a protective cover for thelight source 108 and thecamera 110 and other equipment within theelongated tube 104. In embodiments, the generally transparent material may be comprised of quartz, or the like. - The
second end 118 of theelongated tube 104 is coupled to thehousing 102 using, for example, a threaded fitting. The fitting can be used to provide articulation between thehousing 102 and theelongated tube 104. For example, the fitting can be implemented as a joint. Thesecond end 118 may also be welded to or fastened to the threaded fitting. In an implementation, theelongated tube 104 may comprise an approximately fourteen inch (14″) (355.6 millimeters) long tube that is ten millimeters (10 mm) (0.39 inches) in diameter. Theelongated tube 104 may also be comprised of a rigid material (e.g., titanium), a flexible material (e.g., medical nylon), or other medical grade materials. In some implementations, theelongated tube 104 can be configured to extend and retract. For example, theelongated tube 104 can be configured to telescope, and/or to retract into thehousing 102. - The
insufflator 106 may be used to supply a gas (e.g., CO2) to the abdominal cavity to lift abdominal integument from the internal organs proximate to thefirst end 112 of theelongated tube 104. Theinsufflator 106 may be implemented in a variety of ways. For example, the insufflator may comprise a cartridge-based insufflator, a gas cylinder-based insufflator, an infusion balloon-based insufflator, or other medically suitable portable insufflators. Theinsufflator 106 can be disposed or housed within thehousing 102. - The
light source 108 may assume a variety of configurations. For example, thelight source 108 may be comprised of a light emitting diode (LED), a laser diode, quantum dots, multiple light emitting diodes, multiple laser diodes, or the like. In an implementation, thelight source 108 is disposed at thefirst end 112 proximate to acamera 110, and the power source 116 is coupled (e.g., wired configuration, etc.) to thelight source 108 to provide sufficient operational power to thelight source 108. When theportable laparoscope 100 is in use, thelight source 108 is configured to emit a light to illuminate an area within a field of view of thecamera 110. - The
camera 110 may be configured in a variety of ways. Thecamera 110 may, for example, be comprised of: a pin hole camera, a charge coupled device (CCD) camera, a fiber optic coupled camera, a video camera, and so forth. Thecamera 110 is configured to capture an image in the camera's field of view. Thecamera 110 is disposed proximate to thefirst end 112 and coupled to the power source 116. In an implementation, thecamera 110 may be part of a group ofmultiple cameras 110 disposed proximate to thefirst end 112 and coupled to the power source 116. As illustrated inFIG. 4F ,multiple cameras 110 can be disposed at different locations of thefirst end 112 to capture multiple images from different angles. Themultiple cameras 110 may also be arranged in such a configuration that provides a stereoscopic view of the captured images when displayed. - The
camera 110 is configured to communicate withimage display apparatus 114. For example, one ormore cameras 110 may be communicatively coupled to an electronic device (e.g. adisplay 122, etc.) via a wired configuration, a fiber optic communication, a transmitter/receiver link, or the like. In an implementation, thecamera 110 is configured to transfer the captured image data to animage display apparatus 122 disposed of thehousing 102. - The
image display apparatus 114 may assume a wide variety of configurations, as illustrated inFIGS. 4A through 4E . Theimage display apparatus 114 is configured to display images captured bycameras 110 and/or to transmit the images to a remote display device. For example, theimage display apparatus 114 may include, but is not necessarily limited to: a transmitter 120 configured to transmit captured images; adisplay 122, such as a liquid crystal display (LCD) device or a projection device; and so forth. Thecamera 110 and theimage display apparatus 114 are communicatively coupled together via a wired configuration, a wireless configuration, a fiber optic configuration, or the like. - In an implementation, the
image display apparatus 114 may be configured as adisplay 122 disposed of (e.g., housed within) thehousing 102. For example, thedisplay 122 may be a flip-screen display device, as illustrated inFIG. 4A . As shown, the flip-screen display device may be configured to pivot from a substantially folded position for transportation and storage to a substantially upright position for viewing purposes. In another example, thedisplay 122 may be coupled to the elongated tube 104 (shown inFIGS. 4C , 4D, and 4G). For instance, thehousing 102 may include an aperture to allow viewing of the display portion of thedisplay 122. It is contemplated that thedisplay 122 may be a display device of varying dimensions. For example, thedisplay 122 may be comprised of an approximately 2.5 inch (6.35 centimeter) diagonal LCD device, an approximately 5.8 inch (14.73 centimeters) diagonal LCD device, and so forth. Thedisplay 122 may present the captured image(s) as individual images for a predetermined amount of time. The captured images may also be presented as a sequence of images (e.g., video). In another implementation, thedisplay 122 may comprise a projection device, such as a liquid crystal display (LCD) projector, or the like. Thehousing 102 may be configured to house the projection device. In an implementation, the projection device is configured to project images as a virtual screen to a viewing area. The viewing area may include, but is not necessarily limited to: a projection screen, a wall, or another projection viewing medium. - As illustrated in
FIG. 1 , theimage display apparatus 114 may comprise a transmitter 120. The transmitter 120 may be configured in a variety of ways. For example, the transmitter 120 may be a Radio Frequency (RF) transmitter configured to transmit one or more images captured bycamera 110 via a RF network (e.g., Bluetooth, Wi-Fi, etc.). In another example, the transmitter 120 may comprise a laser diode configured to transmit one or more image(s) via a free-space optical network. The transmitter 120 may be housed within thehousing 102 and coupled to power source 116. - The transmitter 120 can be configured to transmit one or more captured image(s) to a remote display device. The remote display device may be configured in a variety of ways. In an implementation, the remote display device may be comprised of an image display device 124. The image display device 124 may be a monitor (e.g., LCD device, High Definition (HD) display device, etc.) communicatively coupled (e.g., wired configuration, wireless configuration, etc.) to a receiver 126. A receiver 126 is configured to receive the one or more image(s) transmitted by the transmitter 120 and to provide the one or more image(s) to the image display device 124. The receiver 126 may be implemented in a number of ways. For example, the receiver 126 may be a RF receiver configured to receive images from a RF transmitter. In another example, the receiver 126 may be an avalanche photodiode configured to receive images from a laser diode.
- In an implementation, the receiver 126 is configured to receive the image(s) transmitted by the transmitter 120 and to furnish the images to the image display device 124 via a wired configuration. For example, the receiver 126 and image display device 124 may be located in a separate area (e.g., building, room, etc.) from the transmitter 120 and
portable laparoscope 100. - It is contemplated that a
mobile device 128 may be used to view the image(s) furnished bycamera 110. In an implementation,mobile device 128 may be coupled toelongated tube 104 via a wired configuration as illustrated inFIG. 4B . In another implementation, the transmitter 120 may be configured to transmit the captured image(s) to a detachablemobile device 128 via anetwork 130 as illustrated inFIG. 4E . Themobile device 128 may be configured in a variety of ways. For instance, themobile device 128 may be configured as a mobile phone, a smart phone, a laptop computing device, and so forth. Themobile device 128 may include adisplay 132. In an implementation, thedisplay 132 may be integral with themobile device 128. In another implementation, thedisplay 132 may be coupled to themobile device 128 via a wired configuration. For example, the transmitter 120 may transmit the captured image(s) to amobile phone 128 via thenetwork 130. Themobile phone 128 furnishes the captured image(s) to thedisplay 132 for display. In another example, the transmitter 120 may transmit the captured image(s) to alaptop computer 128 via thenetwork 130. Thelaptop 128 furnishes the captured image(s) to thedisplay 132 for display. - The
network 130 is representative of a variety of different communication pathways and network connections that may be employed, individually or in combinations, to communicate among the components of theportable laparoscope 100. Further,network 130 is representative of a variety of different types of networks and connections that are contemplated including, but not necessarily limited to: the Internet; an intranet; a satellite network; a cellular network; a mobile data network; wired and/or wireless connections; and so forth. - Examples of wireless networks include, but are not necessarily limited to: a free-space optical transmission network, a wireless LED network, as well as networks configured for communications according to: one or more standard of the Institute of Electrical and Electronics Engineers (IEEE), such as 802.11 or 802.16 (Wi-Max) standards; Wi-Fi standards promulgated by the Wi-Fi Alliance; Bluetooth standards promulgated by the Bluetooth Special Interest Group; and so on. Wired communications are also contemplated such as through universal serial bus (USB), Ethernet, serial connections, and so forth. As illustrated in
FIG. 1 , theportable laparoscope 100 includes a power source 116. In an implementation, the power source 116 may comprise a battery that is configured to provide sufficient operational power to the various electronic components associated with or coupled to theportable laparoscope 100. For instance, in an implementation, the battery provides sufficient operational power to operate theimage display apparatus 114, theinsufflator 106, thecamera 110, and thelight source 108. It is contemplated that sufficient operational power may be defined as each electronic device powered by the battery receiving enough power to be fully operational according to the specifications of each device for a definite amount of time. - In
FIG. 1 , thelaparoscope 100 is depicted as including a processor 134 and a memory 136. The processor 134 provides processing functionality for theportable laparoscope 100 and may include any number of processors, micro-controllers, or other processing systems and resident or external memory for storing data and other information accessed or generated byportable laparoscope 100. The processor 134 is configured to execute one or more software program(s).
