  • DETAILED DESCRIPTION
  • Described herein is a system for verifying a medical procedure site or surgical location for ensuring medical procedure on a correct side of a body of a patient. The system includes a pointing device, a receiver, and a validater. The pointing device transmits location data to a receiver from several reference points on the body of the patient and a planned medical procedure site on the body of the patient. The validater receives medical procedure plan data associated with the patient and compares the medical procedure plan data with the location data to verify the validity of the planned medical procedure site.
  • FIG. 1 is a block diagram illustrating one embodiment of a system for indicating a medical procedure site. Prior to surgery, for example, at a doctor's office, a digital image 102 of a portion of a body of a patient is displayed on a display device 106. The digital image 102 may include for example, a CT scan, X ray, or other types of digital images.
  • The physician uses an input device such as a mouse to mark the location of a surgery site 104 on digital image 102. In one embodiment, the digital image 102 is oriented according to the body of the patient. In other words, the left foot is represented as the left foot. Display device 106 communicates with physician's office server 108. The information of the surgery site is stored on physician's office server 108 and communicated to operating room server 112 via a computer network (Internet 110). For example, operating room server 112 may located at a hospital where the surgery is to take place. Other pertinent data (patient record) associated with the patient may also be transmitted to operating room server 112.
  • FIG. 2 is a block diagram illustrating one embodiment of a system 200 for verifying a planned surgery site 230. The body of the patient 218 is laid on an operating table 216. In one embodiment, patient 218 is faced up with his back against the table 216. System 200 includes a handheld device 210 such as a pointing device, a receiver 208 such as a pointing device reader, an operating room booking sheet 212, and a booking sheet reader 206, an operating room server 204, a digital imaging device 214, and an alarm system 202.
  • In one embodiment, booking sheet reader 206 includes a bar code scanner or any other type of machine readable marking configured to read data (e.g. a bar code) from operating booking sheet 212 and transmit the data to operating room server 204. Alternatively, data from booking sheet 212 may have been already communicated electronically from a physician's office or at pre-registration at the hospital to operating room server 204. In another embodiment, information about a patient is entered manually into operating room server 204.
  • Booking sheet 212 includes patient information such as a booking number, the name of the patient, date of birth, sex, address, telephone numbers, hospital, surgeon name, date of surgery, nature of surgical procedure, and side of which the surgical procedure is to be performed among others. Additional information can include allergies, insurance information, and diagnosis codes, etc. . . .
  • In one embodiment, a barcode generator is used to generate (not shown) a barcode on booking sheet 212. Barcode generator includes any software or hardware system commonly used to generate barcodes or other machine readable markings. Booking sheet 212 includes a uniquely generated barcode associated with the patient information. Those of ordinary skills in the art will recognize that other types of machine readable marking may be used such as Radio Frequency Identification (RFID). The barcode may be in the form of a sticker affixed to booking sheet 212.
  • In one embodiment, booking sheet 212 is generated prior to the surgery at the hospital. For example, booking sheet 212 may be generated at the time of registration of the patient.
  • Digital imaging device 214 includes a display device showing a digital image 102 along with the location of the surgery site as marked by the physician or surgeon in FIG. 1. In one embodiment, operating room server 204 verifies that the location of the surgery site 104 from digital image 102 corresponds to data from booking sheet 212. Operating room server 204 issues a warning notification with alarm system 202 when the location of the surgery site 104 from digital image 102 does not match the data from booking sheet 212.
  • In another embodiment, digital imaging device 214 display the digital image 102 overlap on another digital image generated by operating room server 204. For example, a CT scan of the left foot of the patient may be overlap with a live outline image of the body of the patient as generated by operating room server 204. The outline image may be a two-dimensional or three-dimensional picture.
  • In one embodiment handheld device 210 (e.g. infrared pen) wirelessly communicates coordinates and location data to receiver 208 (e.g. infrared receiver). The location data from handheld device 210 is relative to receiver 208. Prior to the surgery on patient 218, a staff or physician uses handheld device 210 to mark the location of several reference points along the body of patient 218 as instructed by the handheld device 210 or server 204. For example, system 200 may request the staff to point to a reference point 220 on the head of patient 218. Handheld device 210 may include a switch (not shown) on which the staff can click when the handheld device at the reference point. Location data from reference point 220 is then transmitted to receiver 208. In another embodiment, upon depressing the switch, receiver 208 reads the location of handheld device 210 relative to receiver 208.
  • FIG. 2 illustrates an example of reference points that include, left shoulder 222, right shoulder 224, right foot 226, and left foot 228 among others. In one embodiment, the reference points form an outline of the body of patient 218. A minimum number of reference points allows for receiver 208 or operating room server 204 to determine an orientation of the body of patient 218. In other words, receiver 208 and operating room server 204 are capable, after receiving the reference points, of determining the left side and right side of patient 218.
  • After pointing to the reference points, the user/staff is asked to place handheld device 210 on the planned surgery site 230 and to click the switch on handheld device 210. Coordinates and location data of the planned surgery site 230 are then transmitted to receiver 208. In another embodiment, upon depressing the switch, receiver 208 reads the location of handheld device 210 relative to receiver 208.
  • As such, receiver 208 and operating room server 204 are then capable of determining whether the planned surgery site 230 is located on the left or right side of the patient 218 based on the data received from handheld device 210.
  • In another embodiment handheld device 210 (e.g.—a marker) deposits a visual indicator (e.g. ink) on the skin of the patient. Receiver 208 (e.g. a camera) can be configured to detect the visual indicator and determine the relative position of the visual indicator with respect to the receiver.
  • The planned surgery site is the location where the surgeon is planning to operate on. It may or may not be the actual surgery site 104 as prescribed in booking sheet 212. Thus, the term “planned surgery site” is used to distinguish from the “surgery site” as prescribed by the surgeon in digital image 102 or in booking sheet 212.
  • The medical procedure is not limited to surgery, but also includes other surgical and non-surgical medical procedures such as filling a tooth cavity at a dentist, removing a tooth, examining an eye or ear, putting a cast on a limb, acupuncture on a hand, performing a CT scan or X ray on a body part, etc. . . .

Processing device 320 is configured to execute a patient body calibration module 322 and a surgery location validater module 324. Patient body calibration module 322 is configured to determine the orientation of the body of the patient with respect to a fixed pre-determined reference (such as receiver 208, operating table 216 or the operating room). In other words, patient body calibration module 322 is able to determine a left or right side of the patient 218. Surgery location validater module 324 is configured to determine whether the planned surgery site is located on the left or right side of patient 218 and to compare the side of the planned surgery site with the side of the location marked on digital image 102 received at digital imaging interface 304. In another embodiment, surgery location validater module 324 is configured to determine whether the planned surgery site is located on the left or right side of the patient and to compare the side of the planned surgery site with the side of the location prescribed from booking sheet 212 and received from booking sheet data interface 302.
  • Storage device 310 is configured to store booking sheet data 312, digital imaging data 314, calibration data 316, and handheld device data 318. Calibration data 316 includes the orientation (where the left and right sides are) of the body of patient 218 as determined by patient body calibration module 322. Handheld device data 318 includes coordinates/location data received from handheld device 210 or as determined by receiver 208.
  • Audio/visual input/output 326 is configured to issue an audio and/or visual warning triggered by surgery location validater module 324 when the planned surgery site does not corresponding to the surgery site prescribed in booking sheet 212 and/or as indicated in digital image 102 of the portion of the body of patient 218.
