Various embodiments disclosed herein relate to electronic surgical needle counting systems and methods.
There are many tools used during medical procedures, such as surgery. These tools may include surgical items, such as surgical needles, sponges, retractors, forceps, scalpels, clips, and clamps. Because of the complexity of procedures and number of surgical items used, it is not uncommon for one of those items to be left inside the patient after surgery. It is so common that medical professionals have introduced the vernacular “retained surgical items” to describe these events. Environmental settings can increase the likelihood of surgical bodies left in the patient after surgery, such as emergency and urgent procedures, or complications and unexpected changes during the procedure.
Retained surgical items can be an issue for patients, surgeons, hospitals, and the entire medical team, as they can have both medical and legal implications. They can have potentially harmful consequences for the patient, including additional surgeries, pain abscesses, perforations, punctures, obstructions, and death. This surgical equipment may remain in a patient for days, months, or even years before manifesting as inflammatory reactions. During this period, the retained surgical item may migrate to different parts of the body, potentially causing additional damage and putting the patient at increased risk of one of the many painful consequences. Retained surgical items can also have costly consequences for doctors and hospitals, such as legal costs, operating room time, and x-ray costs. While there are current controls in place in hospitals to prevent retained surgical bodies, human error can affect the success of these methods. Thus, there is a need for a more effective way to account for surgical bodies before, during, and after surgery.
The disclosure describes methods of using a surgical needle counting system. The surgical needle counting system may include a stand, a camera coupled to the stand, a touch screen device communicatively coupled to the camera, a processor system communicatively coupled to the camera, and memory communicatively coupled to the processor system. The memory may comprise executable instructions that, when executed by the processor system, cause the processor system to effectuate operations.
The operations may comprise receiving a first input that may include at least one of a style, dimension, and an initial quantity of at least one surgical needle prior to the at least one surgical needle entering the surgical field. The operations may also include capturing an image of the at least one surgical needle after at least one of the at least one surgical needle has exited the surgical field. The operations may also consist analyzing the image to determine a final quantity of the at least one surgical needle after the at least one of the at least one surgical needle has exited the surgical field. The operations may further include determining whether the initial quantity equals the final quantity.

Surgical items mistakenly left in patients after surgery is a costly, but common, problem in hospitals. Current controls to prevent such occurrences oftentimes involve manual counting of each surgical item before and after surgery. Unfortunately, this method is prone to error, and in many cases results may come out correct even though a retained surgical item may be discovered at a later time.
This disclosure provides systems of accounting for surgical items in order to prevent such episodes. Such systems may thereby augment or fully replace current controls to prevent retained surgical items. Embodiments may be implemented in the form of an electronic surgical needle counting system 10 that can provide a controlled count of surgical items—not prone to human error. While the surgical needle counting system 10 is described for use with surgical needles, it should be appreciated that the system 10 can be used to account for any surgical item. Moreover, the system 10 can operate on any processing system available to people outside of the operating room in order to provide higher levels of control for medical and non-medical applications.
As illustrated in
The operations may consist of receiving a first input 22 that may include at least one of a style, dimension, type, curvature, body, point, shape, length, color, an initial quantity 24, and the like of at least one surgical needle 26. The first input 22 may be received by the system 10 prior to the at least one surgical needle 26 entering a surgical field. The operations may also include capturing an image 28 of the at least one surgical needle 26. The image 28 may be captured by the system 10 after at least one of the at least one surgical needle 26 has exited the surgical field. The operations may also comprise analyzing the image 28 to determine a final quantity 30 of the at least one surgical needle 26 after the at least one of the at least one surgical needle 26 has exited the surgical field. Furthermore, the operations may include determining whether the initial quantity 24 equals the final quantity 30.
Referring now to
In some embodiments, the bar code reader 40 may be coupled to the camera 14. For example, the barcode reader 40 and the camera 14 may embody one device coupled to the system 10, such that the camera 14 may be arranged and configured to have the ability to capture the image 28 of the at least one surgical needle 26, as well as have the ability to capture an image of, and read a bar code.
In some embodiments, the stand 12 of the system 10 may define a rectangular shape. The stand 12 may comprise a first sidewall 42, a second sidewall 44 opposite the first sidewall 42, a third sidewall 46 adjacent the first sidewall 42 and the second sidewall 44, an open side 48 opposite the third sidewall 46, a top portion 50, and a bottom portion 52 opposite the top portion 50. In some embodiments, the stand 12 of the system 10 may consist of at least one sidewall. For example, the stand 12 may include at least one of only one sidewall and only two sidewalls, such that the stand 12 may receive surgical tools from multiple sides. In a further example, the stand may include four sidewalls, one of which may open to allow insertion of surgical tools for counting by the system 10.
It should be appreciated that the stand 12 of the system 10 may define any shape deemed appropriate by those skilled in the art, such as rectangular, circular, triangular, and the like. In some embodiments, the stand 12 may define a C-shape, such that the stand 12 may be constructed of one rounded sidewall with an opening through which surgical tools may be inserted for counting by the system 10.
In some embodiments, the stand 12 may be constructed of a translucent material. The translucent material may include at least one of plexiglass, glass, plastic, rubber, silicone, any plastic like material, and the like. The translucent material of the stand 12 may enable a user of the system 10 to view surgical items within the stand 12 being analyzed by the system 10. For example, the system 10 may be used in conjunction with current methods of accounting for surgical items such that the translucent material of the stand 12 may allow the user to conduct a count simultaneously with the system 10. In some embodiments, the stand 12 is comprised of at least one of translucent material, transparent material, opaque material, solid material, and the like.

As illustrated in
For example, the tray 60 may be carried by a member of a medical team during a medical procedure as the member of the medical team collects the at least one surgical needle 26 for counting by the system 10. The adhesive surface 62 of the tray 60 may ensure that the at least one surgical needle 26 does not fall off of the tray 60. This may save time during the surgical procedure, as in the case that the at least one surgical needle 26 falls off of the tray, members of the medical team may be required to spend additional time in the surgical environment looking for the at least one surgical needle 26. In many cases, time in the surgical environment is critical, as it can be costly and maintaining a patient's health may rely upon each moment spent in surgery.
In some embodiments, the tray 60 may be disposable. The tray 60 may be disposable to help support a sterile surgical environment, as the tray 60 may directly contact surgical items after such surgical items are used in a medical procedure. In some embodiments, a plurality of trays 60 may exist in the surgical field. For example, multiple members of the medical team may use the plurality of trays 60 to collect at least one of the at least one surgical needle 26. Each tray 60 may be positioned within the system 10 one at a time, and the system 10 may add the count of the at least one surgical needle 26 on each tray 60 to total the final quantity 30. The plurality of trays 60 may expedite the time to count the at least one surgical needle 26 and may thusly save time in the surgical environment, which, as earlier discussed, may be valuable. In some embodiments, the tray 60 may be re-usable. The re-usable tray 60 may have a removeable adhesive surface 62, such that the adhesive surface 62 may be disposed of with the at least one surgical needle 26 after the at least one surgical needle 26 has exited the surgical field and been accounted for by the system 10.
In some embodiments, the adhesive surface 62 of the tray 60 may define a magnetic surface. The magnetic surface of the tray 60 may be accomplished by incorporating at least one magnetic material into the tray 60. The at least one magnetic material may include at least one of iron, nickel, cobalt, magnesium, lithium, and the like. The magnetic material may comprise small magnetic pieces dispersed throughout a portion of the tray 60 with which the at least one surgical needle 26 may into contact. The magnetic material may also be embodied by at least one magnetic strip placed along the edge of the tray 60. The magnetic surface may be used with surgical items that may comprise magnetic properties, such as surgical needles, forceps, retractors, scalpels, clips, clamps, and the like.
With added reference to
In some embodiments, the system 10 may include a backlight 64 located along the bottom portion 52 of the stand 12. The backlight 64 may be arranged and configured to provide contrast between the at least one surgical needle 26 and the tray 60. The translucent material comprising the tray 60 may allow light from the backlight 64 to partially pass through the tray 60. The light passing through the tray 60 may create a contrast between the light-bearing tray 60 and the opaque-colored nature of the at least one surgical needle 26. The contrast created between the tray 60 and the at least one surgical needle 26 may aid the system 10 in analyzing and counting the at least one surgical needle 26 on the tray 60.
In some embodiments, the tray cover 60b may comprise a numbered surface 63. The numbered surface 63 may be composed of a sponge-like material. The at least one surgical needle 26 may be poked into the sponge-like material of the tray cover 60b, wherein the at least one surgical needle 26 may couple to the tray cover 60b. At least one of the at least one surgical needle 26 may be coupled to a number on the numbered surface 63 of the tray cover 60b such that there is one at least one surgical needle 26 per number. The tray 60a and tray cover 60b may be folded together and the at least one surgical needle 26 may couple to the magnetic suture coupling surface 62. The system 10 may thus augment current manual surgical item counting practices to provide a second, reliable count of surgical items.
As illustrated in
In some embodiments, the magnetic surface of the tray 60a may be accomplished by incorporating at least one magnetic material into the tray 60a. The at least one magnetic material may include at least one of iron, nickel, cobalt, magnesium, lithium, and the like. The magnetic material may comprise small magnetic pieces dispersed throughout a portion of the tray 60a with which the at least one surgical needle 26 may into contact. The magnetic material may also be embodied by at least one magnetic strip placed along the edge of the tray 60a. The magnetic surface may be used with surgical items that may comprise magnetic properties, such as the at least one surgical needle 26, forceps, retractors, scalpels, clips, clamps, and the like.

The operations may also include the camera 14 capturing the image 28 of the at least one surgical needle 26. The camera 14 may capture the image 28 after at least one of the at least one surgical needle 26 has exited the surgical field. As well, the operations may include the processor system 18 analyzing the image 28. The processor system 18 may determine the final quantity 30 of the at least one surgical needle 26 after the at least one of the at least one surgical needle 26 has exited the surgical field based upon the analysis. Furthermore, the operations may include the processor system 18 determining whether the initial quantity 24 equals the final quantity 30.
In some embodiments, the camera 14 may capture a plurality of images 28 wherein a plurality of trays 60 is used to collect the at least one surgical needle 26 from the surgical field. The processor system 18 may analyze each of the plurality of images 28 to determine a quantity of the at least one surgical needle 26 on each tray 60, and add all of the quantities to determine the final quantity 30. Thus, the system 10 may begin accounting for the at least one surgical needle 26 before every at least one surgical needle 26 has been removed from the surgical field. Such systems may aid the medical team in accounting for the at least one surgical needle 26 during surgical procedures wherein multiple surgical needles are used and removed throughout the procedure. The medical team may not have to keep track of which of the at least one surgical needles 26 have been accounted for, but rather let the system 10 count the at least one surgical needle 26 and then dispose of the at least one surgical needle 26 and the tray 60 after counting, wherein the tray 60 is disposable.
Referring now to
In some embodiments, the stand 12 may incorporate a semi-enclosed portion 66. The semi-enclosed portion 66 may be vertically located between the top portion 50 and the bottom portion 52 of the stand 12. Furthermore, the camera 14 and the bar code reader 40 may be located within the semi-enclosed portion 66. The semi-enclosed portion 66 may be constructed of the same material as the stand 12. The semi-enclosed portion 66 may include openings in which the camera 14 and the bar code reader 40 may be positioned such that the camera 14 and the bar code reader 40 may be able to capture items that may be placed on the bottom portion 52, such as the tray 60 of at least one surgical needle 26 and a package of at least one surgical needle 26 that may include a bar code.
In many embodiments, the touch screen device 16 may incorporate the processor system 18 and the memory 20. The touch screen device 16 may be communicatively coupled with the processor system 18 and the memory 20. The memory 20 may comprise executable instructions that may be effectuated by the processor system 18. Such executable instructions and order thereof may be configurable to fit the needs of the user of the system 10. The touch screen device 16 may be communicatively coupled with the camera 14 such that when the camera 14 captures an image 28 of the at least one surgical needle 26 on the tray 60, the processor system 18 may analyze the image 28 and determine at least one of style, dimension, type, curvature, body, point, shape, length, color, the initial quantity 24, and the like of the at least one surgical needle 26.
The touch screen device 16 may also be communicatively coupled with the bar code reader 40 such that when the bar code reader 40 detects and reads a bar code, the processor system 18 may analyze information associated with the bar code. The system 10 may thus be enabled to gather information associated with the at least one surgical needle 26 when the at least one surgical needle 26 is within a package that may comprise the bar code. The information associated with the bar code may include at least one of style, dimension, type, curvature, body, point, shape, length, color, the initial quantity 24, and the like of the at least one surgical needle 26. The information associated with the bar code may be processed by the processor system 18 to constitute the first input 22.
As illustrated in
In some embodiments, the system 10 may consist of a stand 12, a camera 14 coupled to the stand 12, a touch screen device 16 communicatively coupled to the camera 14, a processor system 18 communicatively coupled to the camera 12, and a memory 20 communicatively coupled to the processor system. As illustrated in
In some embodiments, a user of the system 10 may enter the first input 22 manually. The user may utilize a user interface incorporated in the touch screen device 16 to input the initial quantity 24 of the at least one surgical needle 26. In some embodiments, the user may utilize the user interface on the touch screen device 16 to adjust the initial quantity 24 of the at least one surgical needle.
In some embodiments, the system 10 may include a bar code reader 40. The bar code reader 40 may be coupled to the stand 12 and communicatively coupled to the touch screen device 16. According to some embodiments, methods may include the system 10 receiving the first input 22 (at step 900) via the bar code reader 40 prior to the at least one surgical needle 26 entering the surgical field (at step 902). The at least one surgical needle 26 may be contained within a package prior to use, the package comprising a bar code. The bar code reader 40 may read the bar code of the package such that the processor system 18 receives information regarding the at least one surgical needle 26, such as the initial quantity 24. The processor system 18 of the touch screen device 16 may comprise a software program that may have a built-in database of needle styles and dimensions. The processor system 18 may analyze the bar code of a package of at least one surgical needle 26 and retrieve information from said database to receive the first input 22.
With continued reference to
In some embodiments, methods may include displaying a notification on the touch screen device 16. The notification may be regarding whether the sum of the first initial quantity 74 and the second initial quantity 76 equals the sum of the first final quantity 80 and the second final quantity 82. In some embodiments, the touch screen device 16 may operate on a processor system 18 available to people outside of the operating room, such that the notification may appear on devices outside of the operating room operating on the processor system 18.
Furthermore, as shown in
