Description

    RELATED APPLICATIONS
  • This application claims the benefit of and priority to U.S. Provisional Application Ser. No. 60/912,337, filed Apr. 17, 2007, entitled METHODS AND INSTRUMENTS FOR IMAGING IN MEDICAL OR SURGICAL PROCEDURES and U.S. Provisional Application Ser. No. 61/016,557, filed Dec. 24, 2007, entitled COMPACT CAMERA, the contents of which are hereby incorporated by reference as if recited in full herein for all purposes.
  • BACKGROUND
  • This inventive subject matter generally relates to imaging systems and methods for surgical or other medical procedures. More particularly, it relates to compact imaging systems for use on instruments for open surgery.
  • When a surgeon is performing an open surgery, the area of interest may be too small for more than one surgeon to observe. Or the area of the surgical table may be too crowded and not easily viewed by other medical personnel who may be interested in viewing the surgical site and procedure. Some surgical rooms have overhead cameras that allow others to view a surgical site, but the movement of persons around the table and angle of viewing may preclude a view of the area of interest. Accordingly, there is a need for improved imaging systems and methods of dissemination of imaging data that facilitate collaboration, participation, and surgical and medical training.
  • There are several types of surgery. The first is endoscopic surgery, such as laparoscopic surgery, in which a small incision is made in order to insert working instruments and an endoscopic viewing instrument. Imaging systems for endoscopic surgery are well known and are typically located either on the distal end of the insertion portion of an instrument or on its proximal end (using rod lens or fiber based endoscope). A second type of surgery is endoluminal (natural orifice) surgery, in which no external incision is required. U.S. Pat. No. 4,905,670, by Adair, discusses a cervical speculum with a clip-on camera, and therefore belongs to this second category of surgery. Other prior art includes U.S. Pat. Nos. 5,667,473, 5,667,478 and 5,735,792. In these patents, the instruments are endoscopic instruments rather than instruments for open surgery, and one or more optical fibers are run along the instruments in order to view the surgical site without the need for a separate endoscope.
  • A third type of surgery is open surgery, in which a larger incision is made in order to view the site directly and to maneuver the working instruments. This type of surgery can be observed without an insertion of an imaging system.
  • Although many video cameras and imaging systems have been developed for endoscopic applications, the range of video imaging systems for open surgical applications is much more limited. For example, some operating rooms have overhead cameras, but the view provided by the camera may be blocked by the hands or instruments of the surgical personnel. Furthermore, the camera may not have sufficient magnification to give observers and other members of the surgical team a clear picture of the surgical site.
  • Accordingly, the prior art does not disclose or suggest imaging systems or methods that are suitable for use in the viewing environment of open surgery. Nor does the prior art disclose methods for extending the audience in open surgery or methods of dissemination of the imaging data or methods of collaboration in response to imaging data.
  • Further, there is a need for systems that have efficiently arranged electronic components and connection to provide a compact system.
  • SUMMARY
  • The inventive subject matter overcomes problems in the prior art by providing a camera system and methods with the following qualities, alone or in combination:
  • In certain respects, the inventive subject matter is directed to permanently or removably mounted cameras that are mounted on a non-insertion portion of a medical instrument, and to methods of making and using the same. The medical instrument with associated camera may be used in open surgery. Open surgery is a method of surgery in which an incision is made to enable direct viewing of and access to the surgical site, an instrument is introduced into the surgical site, and a camera attached to or integrated in the instrument is used to provide a displayed image in addition to the direct viewing of the site by the surgeon. Some times structural pathology prevents direct visualization, and the only means to see the operated site would be through a camera mounted on a tool. By placing the camera on the instrument, the site of interest may be kept in clear, direct view, unobstructed by hospital personnel or objects. Accordingly, the inventive subject matter allows for better-informed judgments from consulting personnel, such as specialist physicians or surgeons, or for better training of students in an educational setting, for example. The inventive subject matter is particularly advantageous at allowing participation of remotely located persons, who may be participating via a telecommunications or data network.
  • Various methods are within the scope and contemplation of the inventive subject matter. For example, in one possible embodiment, the inventive subject is directed to a method of imaging in open surgery comprising providing an instrument with an associated imaging system and acquiring imaging data with the camera and presenting it on a presentation device, such as a computer monitor, television, or via a printer.
  • In another possible embodiment, the inventive subject matter is directed to a method of communicating imaging data comprising providing a medical instrument, the instrument comprising a distally disposed working portion for working in a surgical or medical procedure, and a proximally disposed non-working portion having an associated imaging system, the non-working portion being on a non-insertion portion of the instrument.
  • In other embodiments, the inventive subject matter is directed to a compact video camera that is particularly suited to give a close, unobstructed view of the surgical site in open surgery. The camera may be attached to a shaft of a surgical instrument so as to image the area of the working element at the distal end of the instrument. The camera may be self-contained, requiring no intervening fiberoptics or modification of the instrument to which it is to be attached.
  • In some embodiments, the camera is produced using novel components and methods of manufacture that facilitate small size, high reliability and low cost. Although the camera is described below with particular reference to surgical applications, the novel features that are described below may similarly be implemented in cameras and imaging systems for other uses. In one possible embodiment, an electronic assembly comprises a non-conducting substrate which has front and back sides and comprises through-wires molded into the substrate so as to pass through the substrate from the front side to the back side; and an integrated circuit device, which is fixed to the front side of the substrate and electrically connected to the through wires at the front side of the substrate. In the foregoing embodiment, the integrated circuit device may include an image sensor. In the foregoing embodiment, the communications interface may include a cable connecting to the image sensor via the through wires so as to convey electronic images from the image sensor to a remote console. In the foregoing embodiment, the substrate may include glass. In the foregoing embodiment, the integrated circuit device may be electrically connected to the wires at the front side of the substrate by wire bonding. In the foregoing embodiment, at least one circuit component may be mounted on the back side of the substrate and electrically connected to one or more of the through-wires. The foregoing embodiment may also include a housing for enclosing the assembly that has a compact shape for association with a shaft portion of a surgical instrument, the shape being designed so as not to substantially impede the use of the surgical instrument, which shape includes a length not exceeding the length of a non-working portion of the surgical instrument and a width or diameter not exceeding about 3 times the width or diameter of the shaft portion. In the foregoing embodiment, the housing may include a connecting means for fastening the housing onto the shaft portions. In the foregoing embodiment, the connecting means may include a clip. In the foregoing embodiment, the image sensor may include a solid-state light source for illuminating a surgical site. In the foregoing embodiment, the assembly may also include a solid-state light source for illuminating a surgical site. In the foregoing embodiment, the image sensor may include a CMOS or CCD image sensor. In the foregoing embodiment, the image sensor may include a CMOS or CCD image sensor. In the foregoing embodiment, the system may be configured with a communications interface for communicating imaging data to a remote location. In the foregoing embodiment, the system may be configured with a communications interface for communicating imaging data to a remote location.
  • In another possible embodiment, a method of making an electronic assembly, may include providing a material for forming a non-conducting substrate, which has front and back sides; molding the material together with wires so that the wires pass through the substrate from the front side to the back side; and fixing an integrated circuit device to the front side of the substrate and electrically connecting it to the through wires at the front side of the substrate. In the foregoing embodiment, the integrated circuit device may include a pixellated, electronic image sensor. In the foregoing embodiment, the method may also include placing the assembly into a housing for enclosing the assembly that has a compact shape for association with a shaft portion of a surgical instrument, the shape being designed so as not to substantially impede the use of the surgical instrument, which shape includes a length not exceeding the length of a non-working portion of the surgical instrument and a width or diameter not exceeding about 3 times the width or diameter of the shaft portion.
  • In another possible embodiment, an assembly of an imaging system, may include a non-conducting substrate, which has front and back sides and comprises through-wires molded into the substrate so as to pass through the substrate from the front side to the back side; and a pixellated, electronic image sensor, which is fixed to the front side of the substrate and electrically connected to the through wires at the front side of the substrate; and a housing for enclosing the assembly that has a compact shape for association with a shaft portion of a surgical instrument, the shape being designed so as not to substantially impede the use of the surgical instrument, which shape includes a length not exceeding the length of a non-working portion of the surgical instrument and a width or diameter not exceeding about 3 times the width or diameter of the shaft portion.
  • Another possible embodiment may include a communications interface associated with the imaging system for communicating imaging data to a remote location. In the foregoing embodiment, the substrate may include a plastic or ceramic based material.
  • These and other embodiments are described in more detail in the following detailed descriptions and the figures. The foregoing is not intended to be an exhaustive list of embodiments and features of the present inventive subject matter. Persons skilled in the art are capable of appreciating other embodiments and features from the following detailed description in conjunction with the drawings.

  • DETAILED DESCRIPTION
  • Representative embodiments according to the inventive subject matter are shown in FIGS. 1-8.
  • In a most general sense, the inventive subject matter is directed to the use of an imaging system. As used herein, “imaging system” typically means an objective optic element or elements and a device on which the objective optics convey the image for capture. There are many known cameras that are representative of imaging systems. The imaging system illustrated in the figures is an electronic imaging system comprising an objective lens and a pixellated, electronic image sensor, such as a CCD or CMOS sensor.
  • The imaging system may capture an image in an open surgical procedure to provide additional viewing opportunities beyond the restricted view generally presented to only the operating surgeon.
  • The camera may be attached, integrated in, or otherwise connected to one of the instruments used in the operation in such a way that it will not complicate any technical procedure done by the instrument from one end, and will allow anyone in the operating room, or in a remote location, to see the working area from a different angle or point of view on a monitor or other through another output device, such as printer. As used herein, an instrument “associated” with a camera means an instrument with a camera that is physically coupled to the instrument, in a removable or non-removable manner, such as by mounting or attaching the camera on or within a known instrument or making an instrument with an integrated camera feature on or in the instrument.
  • Typically, the instrument on which the imaging system is associated will have a distally disposed working portion for working in a surgical or medical procedure, and a proximally disposed non-working portion having an associated imaging system, the non-working portion being on a non-insertion portion of the instrument. As used herein, “non-insertion portion” means a portion that is generally kept above the plane of a body surface; however, if there is a wide opening or recess below the plane, the non-insertion portion may be used below the plane of the body surface, if such use is consistent with open-type surgery.
  • The camera may be configured with a battery or coupled to a remote power source. The power source may be the same one associated with a medical instrument with which the camera is mounted or otherwise used. The camera may be configured with a configuration for wireless transmission of image data to a received, such as camera control unit (CCU), such communication interfaces including hardware and/or software components and protocols, as are well known to persons skilled in the art.
  • In some embodiments the camera and/or the instrument may be disposable in the context of the medical arts, namely a camera intended for one time use. As used herein, “camera” means a video or still camera.
  • Generally, known camera systems may be adapted for use in the inventive subject matter. Example systems are disclosed in WO2006066022, US2006173242 and US20050250983 which are hereby incorporated by reference in their entireties. Other known systems that have a form that may be adapted for use in the inventive subject matter disclosed herein include capsule-form endoscopic cameras, such as those disclosed in US2006253004 and US2006004256, which are hereby incorporated by reference in their entireties.
  • The following sections provide details of an illustrative camera system according to the inventive subject matter. The examples are strictly for illustrative purposes and are not intended to be limiting of the scope of the inventive subject matter, unless specifically indicated to such (as well as equivalents) in a claim now or in the future appended hereto.
  • FIGS. 1 and 2 schematically illustrate a system 10 for surgery, in accordance with an embodiment of the present invention. FIG. 1 shows a surgeon 12 operating on a patient 14 in open surgery, using a surgical instrument 21. FIG. 2 is a pictorial illustration of instrument 21 showing a miniature camera 20, which is attached to a shaft 22 of the instrument. The term “shaft” as used herein generally means a portion of the instrument between a proximal end 23 of the instrument, which is typically grasped by the operator, and a working element 25 at the distal end. The shaft typically comprises an elongate structure proximal to the working element. The shaft may be cylindrical, as in FIG. 2, but may alternatively have any other suitable profile. The shaft itself may be configured to provide space to house a camera. Alternatively, camera 20 may be attached to shaft 22 by a suitable connecting means, such as a clip 27, or alternatively by any other suitable sort of fastening, such as a screw, adhesives or adhesive strips, straps, hook/loop fasteners (e.g., Velco™). The attachment may be such that the camera may be removed and attached to other instruments, or it may be fixed and substantially permanent.
  • Camera 20 is positioned, as can be seen in the figures, to capture images of an area in the vicinity of working element 25 within the body of patient 14. The camera may have a communications interface for communicating with remote systems. For example, a cable 24 conveys signals from the camera to a video console and display 16. Typically, during use of instrument 21 in open surgery, surgeon 12 makes an incision in the patient's body to provide direct access to the surgical site. The surgeon inserts working element 25 through the incision into the patient's body, while holding proximal end 23 outside the body, and uses the working element in operating on tissue in the body. Camera 20 may remain outside the body during the procedure. At the end of the procedure, the surgeon closes the incision.
  • In contrast to endoscopic procedures, working element 25 in open surgery generally remains directly visible to the surgeon during the surgery. On the other hand, other members of the surgical team, as well as observers, may be unable to see the area of the working element because their view is blocked by the surgeon himself or by other objects or personnel. These team members and observers are able to observe the images captured by camera 20 on display 16 in real time. The display may be at a location remote from the patient, including locations in the operating room that are not directly adjacent to the operating table, as well as locations in other rooms or buildings.
  • Additionally or alternatively, the output of camera 20 may be transmitted over a communications network or fed to a video recorder or other video processing equipment (not shown). The image data produced by the camera may be used in various ways, including medical or surgical training; participation or collaboration in the surgical procedure in progress or in a subsequent procedure on the same patient; review of recorded procedures; editing, enhancement, image extraction or other modifications on the image data; archiving; and ensuring compliance with rules or policies, such as in regulatory submissions.
  • In open surgery there is generally sufficient light cast by overhead lamps and, in some cases, by the surgeon's headlamp to permit camera 20 to capture clear images without supplemental lighting. Optionally, camera 20 may also comprise an integrated light source, such as a suitable light-emitting diode (LED), for illuminating the area under view. Alternatively, a separate light source may be attached to one of the shafts of instrument 21. (These optional additional light sources are not shown in the figures.)
  • FIGS. 3-6 schematically show details of camera 20, in accordance with an embodiment of the present invention. FIG. 3 is a pictorial external view of the camera, while FIG. 4 shows some of the internal elements of the camera in a transparent view. FIG. 5 is an exploded view, and FIG. 6 is a sectional view taken in a vertical plane containing the line VI-VI in FIG. 3. Insets in FIG. 6 also show enlarged views of certain details of the construction of the camera.
  • The components of camera 20 are contained in a case, which comprises a chassis 26 that is closed by a cover 28. For the application illustrated in FIG. 2, for example, the case may have an outer diameter of approximately 5 mm and a length of 15 mm, but larger or smaller dimensions are also possible depending on application requirements. Chassis 26 contains a lens assembly 30, which forms an image of the area of interest on a sensor assembly 40. The sensor assembly comprises an electronic image sensor 44, such as a pixellated CCD or CMOS integrated circuit device comprising an array 42 of sensor elements. In the configuration shown in FIG. 2, lens assembly 30 may have a total field of view of about 60° in the object space, with a working distance (depth of field) from 100 to 250 mm, but other optical configurations may alternatively be used as appropriate.
  • Lens assembly 30 in this example comprises lenses 32, 34 and 36. These lenses typically have a diameter of about 2 mm or less. Accurate assembly of such small optics to within design tolerances is understandably difficult when conventional methods of assembly are used. Typically, careful alignment and testing are required to ensure that the lenses are properly positioned.
  • In camera 20, however, for ease and accuracy of assembly, chassis 26 comprises a lens holder 52, which has an open cylindrical groove 58 for receiving the lenses. In the context of the present patent application and in the claims, the term “open cylindrical groove” refers to a groove having the shape of an inner surface of a cylinder but extending in angle around only part of the circumference of the cylinder, leaving an opening at one side of the cylinder for insertion of the lenses. The groove may advantageously be hemi-cylindrical, as illustrated in the figures. The groove is shaped and sized precisely to receive the lenses. Proper spacing between the lenses, in accordance with the optical design of assembly 30, is maintained by spacers 38 and 56. These spacers may be separate components, such as spacer 38, that are inserted into groove 58, or they may alternatively be built into the groove, as is spacer 56, in the form of a step in the groove diameter. Spacer 56 effectively creates a slot 54 for accommodating lens 32.
  • Thus, all that is necessary to assemble optical assembly 30 in camera 20 is to fit lens 32 into slot 54, and to fit lenses 34 and 36, separated by spacer 38, into groove 58 behind spacer 56. Alternatively, spacer 38 may be replaced by a fixed, built-in step like spacer 56. Lens holder 52 is produced with sufficient accuracy so that the lenses, once inserted in this manner, are in the proper positions without requiring additional alignment or testing. The lenses may be glued into the lens holder in these positions. When cover 28 is then closed over chassis 26, it holds the lenses securely in place.
  • Image sensor 44 is mounted on a non-conducting substrate 46. To minimize the diameter of camera 20, it is desirable that the diameter of substrate 46 be as small as possible, while still containing sufficient through-wires 48 to convey the necessary signals to and from sensor 44. For this reason, it has been found advantageous to make substrate 46 from a moldable material, such as glass, or other non-conducting substrate, with through-wires 48 molded into the glass at the time of fabrication of the substrate. In other words, instead of drilling vias through the substrate and then filling the vias with metal, as is common in methods of printed circuit production that are known in the art, through-wires 48 are held in place while substrate 46 is molded, so that no subsequent drilling is required. As a result, the through-wires may have narrow diameter, typically on the order of 100 μm, and may be spaced close together without compromising the strength and integrity of the substrate. Although substrate 46 is described above as comprising glass, other types of non-conducting moldable materials may alternatively be used for this purpose. In addition to glass, other non-conducting substrates in which wires may be molded, or which otherwise may be similarly formed around the wires, include plastics and ceramic based materials. The terms “moldable” and “molding” and “molded” are generally used herein to refer to any manner of forming a substrate integrally around the wires to create a monolithic structure. Examples include molding using meltable or fusible solid substrates or powders, and casting around the wires using powders or liquids. For example, resins may be poured around the wires, which solidify to create a solid substrate. Powders may be congealed around the wires by adding liquids, heat, and/or pressure. Examples of specific materials include borosilicate glass, which, for example, may be integrated with covar pins. The substrate may use, for example, ceramic based on Cerium Gadolinium, or plastics of PMMA, PVC, ABS, and other known insulating plastics.
  • To produce sensor assembly 40, image sensor 44 is aligned and fixed to the front side of substrate 26, using a suitable glue, for example. The image sensor is then connected to wires 48 by bonding fine wires 60 between contact pads (not shown) on sensor 44 and forward ends 50 of wires 48, which are typically cut so as to protrude slightly above the surface of substrate 46. Alternatively, printed circuit traces (not shown) may be formed on the front side of the substrate to connect the sensor to wires 48. The rear ends of wires 48, at the back side of substrate 46, are connected to the appropriate conductors in cable 24 (FIG. 2). Optionally, one or more additional circuit components 62 may be attached to the back side of the substrate and connected to wires 48 by wire bonding or printed circuit traces.
  • As shown in FIGS. 5 and 6, the shape and inner diameter of chassis 26 are chosen so that substrate 46 fits snugly into the chassis. Thus, to complete the assembly of camera 20, the assembled sensor assembly 40 is mounted in the chassis and is aligned so that lens assembly 30 casts a focused image onto array 42. The substrate is then glued or otherwise fastened in place, and cover 28 is closed over the lens assembly and sensor assembly. Clip 27 (FIG. 2) may be added (to either chassis 26 or cover 28), and the camera is ready for use.
  • The use of a substrate with molded-in through-wires is advantageous not only for mounting image sensors, but also for mounting other types of circuit components in narrow spaces.
  • FIGS. 7 and 8 schematically illustrate a camera 70, in accordance with an alternative embodiment of the present invention. FIG. 7 is an exploded view, while FIG. 8 is a sectional view, similar to the views of camera 20 shown in FIGS. 5 and 6. Camera 70 includes a chassis 72 and cover 74, as well as other optical and image sensing components as in camera 20. Chassis 72, however, comprises a lens holder 76 that contains a smooth open cylindrical groove, without built-in spacers. Instead, the optical assembly in camera 70 uses an additional spacer 78 between lenses 32 and 34. This arrangement simplifies the manufacture of chassis 72, at the expense of minor additional complication in assembly of the camera.
  • Although cameras 20 and 70 are described hereinabove with particular reference to surgical system 10 and instrument 21, the principles of the design and construction of these cameras may similarly be applied in other imaging applications, and particularly applications that require a very compact camera. By the same token, although the method of intra-operative video imaging for open surgery that is illustrated in FIGS. 1 and 2 is described with specific reference to camera 20, miniature video cameras of other types may likewise be attached to the shaft of a surgical instrument for the purposes of this method. Furthermore, instrument 21 itself is shown purely for the sake of illustration, and cameras may also be attached in this fashion to surgical instruments of other types.
  • In one possible embodiment, the inventive subject matter is directed to a camera for a surgical instrument wherein the camera has a compact shape so as not to substantially impede the use of the surgical instrument, which shape includes a length not exceeding the length of the non-working portion of the surgical instrument to which the camera is associated and a width or diameter not exceeding about 3 times the width or diameter of the shaft portion of the instrument to which the camera is mounted or otherwise associated.
  • Methods of Use
  • Various methods are within the scope and contemplation of the inventive subject matter. For example, in one possible embodiment, the inventive subject is directed to a method of imaging in open surgery comprising providing an instrument with an associated imaging system and acquiring imaging data with the camera and presenting it via a standard data communications interface to a presentation device, such as a computer monitor, television, or via a printer.
