The features and purpose of the invention

Generally, this invention is related to the collapsible radiological imaging unit drape with retractable handle which can prevent contamination to surgical field and reduce the postoperative infection. This collapsible radiological unit drape can be expanded to cover the unsterile part of radiological equipment such as fluoroscopy when it rotates into the sterile surgical field during surgery. It can collapse to attach with the surgical drape side when the unsterile part of radiological equipment is removed from the surgical field. One side of this radiological imaging unit drape with retractable is designed to fixedly attach to the patient’s surgical drape. Another side includes reusable cooperative interconnecting object with retractable handle to hold the radiological imaging unit drape in collapse position. Both sides of the radiological imaging unit drape with retractable handle being interconnected via collapsible interconnecting pouch. The retractable handle is made of hard material which make it possible to be carried with one hand during use. It can be shrunk when surgeon don’t require a lot of space underneath the drape. In case that surgeon need more space underneath the radiological imaging unit drape, the handle can be expanded. The retractable feature of the handle makes it possible to create the handle from hard material while still possible to have compact size packaging.

Background Art

The intraoperative radiological equipment such as fluoroscopy is widely used in orthopaedic trauma, spine surgery, hand and wrist surgery, etc. The intraoperative radiological equipment is used to achieve intraoperative image in antero-posterior view, oblique view or lateral view of concerned body part. To take some intraoperative image, unsterile part of the radiological equipment must be raised upward and stay very close to the operating table, sterile surgical drape and surgical team which can contaminate the entire sterile surgical field. The intraoperative contamination leads to surgical site infection which will severely deteriorate the clinical outcomes and sometimes cause limb loss or death. Currently, to prevent contamination from unsterile part of radiological equipment, the sterile cloth or half sheet is used to cover the unsterile part of radiological equipment that enter into the sterile field. However, this method has several disadvantages as following

1) Time consuming to cover the unsterile part of radiological equipment every time it enter the sterile surgical field.

2) The sterile cloth or half sheet is not specifically designed for this purpose. There are still a risk of contamination through the side of sterile cloth or half sheet.

3) Economical inefficient from wasting many sterile cloths or half sheets in one surgical operation.

4) The fear of contamination, time and economical inefficient of using the half sheets may lead surgeon to limit the use of fluoroscopy which may have negative effect on patient.

To solve the problems as mentioned above, the collapsible radiological imaging unit drape is created. The drawback of radiologic unit drape in the prior art such as in Thai petty patent number 1603001163 is it’s requires 2 hands to carry the long, soft and pliable handle during use. Without 2 hands holding the long and soft handle, there is a chance of handle falling and get contamination. Thus, a radiologic unit drape with hard, retractable handle is desirable. The hard retractable handle can be shrunk when surgeon don’t require a lot of space underneath the drape which make it easier to carry with one hand. In case that surgeon need more space underneath the radiological imaging unit drape, the handle can be expanded. The handle that can shrink into short length also be advantageous to make the compact size packaging.

Disclosure of Invention

Generally, this invention is related to the collapsible radiological imaging unit drape with retractable handle which can prevent contamination to the surgical field and reduce of postoperative infection. This collapsible radiological unit drape with retractable handle can expand to encase the intraoperative radiological equipment such as fluoroscope when it rotates into the sterile surgical field during surgery. It can be collapsed to attach with the surgical table side when an unsterile part of radiological equipment is removed from the surgical field. This radiological drape is designed for single use.

In the drawing, Figure 1 illustrate a radiological imaging unit drape with retractable handle (1) which is attached to the surgical drape (2). The sterile area is demonstrated as all of the area above the dash line (3) including surgical drape (2), prepped patient’s limb (4) and upper body of surgeon (5). This radiological imaging unit drape with retractable handle is designed to protect mentioned sterile areas (2), (4), (5) from unsterile part of radiological equipment contamination such as fluoroscopy machine (6). The fluoroscopy machine consists of upper imaging unit (7), lower imaging unit (8), C shape arm (9) which connect upper (7) and lower imaging unit (8). To take some intraoperative image such as in Figure 2, an unsterile part of the fluoroscope (8) must be raised upward and stay over the dash line (3) which can contaminate the entire sterile surgical field (2), (4), (5). In one operation, surgeon may need to rotate fluoroscopy arm into this position many times. Currently, to prevent contamination from unsterile part of fluoroscopy machine, the sterile cloths or half sheets are used to cover the nonsterile part of fluoroscopy (8) that enter into the sterile field which is waste a lot of time, inadequately protect the sterile field and expensive. The invention of radiological imaging unit drape with retractable handle (1) can address all of these problems. It’s attached to the surgical drape in collapse position which is not to interfere with operative procedure and the surgical team (Figure 1) then it can be deployed to cover the unsterile part of fluoroscopy (Figure 3). This radiological unit imaging drape with retractable handle can be repeatedly deployed and collapsed to reattach with the surgical drape side during the operative procedure.

The radiological drape of the current invention will be better understood with reference to the figures. Referring initially to Figure 4, illustrate details of radiological imaging unit drape with retractable handle when the handle stays in shrinking position. The radiological drape of the current invention consists of proximal side (12) which comprises of adhesive strips to attach with the sterile surgical drape (2). Other options for attaching the proximal side (12) of radiological imaging unit drape to the surgical drape (2) such as hooks and loops strip, clip, etc. also can be used. The radiological drape of the current intervention also consists of distal side (14). The proximal (12) and distal side (14) of the radiological drape being interconnected via collapsible interconnecting pouch which consists of at least 4 walls including upper wall (16), 2 side walls (17) and front wall (18). The internal opposing surface of proximal side (12) and distal side (14) are installed with cooperative interconnecting object on the proximal side (13) and on the distal side (15) to allow repeatedly deploy and collapse the interconnecting pouch during surgical procedure. The cooperative interconnecting objects such as hooks and loops, magnet, adhesive, ropes, latch, buttons, snaps, etc. also can be used. The upper part of the interconnecting pouch will be attached with at least one elastic strip (19) to pull the distal side back to the proximal side. The elastic strip can be installed to the interconnecting pouch by passing through the upper or lateral wall tunnel (20) with 2 fixation spots at both ends of the elastic strip. By the way, the elastic strip also can be directly attached on upper wall (16) or side wall (17) of the interconnecting pouch by adhesive, sewing, heat sealing, etc. The distal side is also incorporates with retractable handle (21) which made of hard material then make it possible to be carried with one hand during use. This type of handle can be shrunk when surgeon don’t require a lot of space underneath the radiological imaging drape which make it easier to carry with one hand. In case that surgeon need more space underneath the radiological imaging unit drape, the handle can be expanded. The handle that can shrink into short length also be advantageous to make the compact size packaging.

Figure 5 illustrate a radiological imaging unit drape with retractable handle while the handle is stretched into fully expand position. Figure 6 illustrate a perspective view illustrating a side view of radiologic unit drape with retractable handle which is deployed to cover the unsterile part of fluoroscopy.

Figure 7 is a perspective view illustrating a side view of radiological unit drape with retractable handle which is collapsed to attach with surgical drape. The dimension of the radiological draped of the current intervention (1) can be symmetry or asymmetry but should have enough length to fully cover the unsterile part of radiological equipment that’s moved into the sterile field. The lower edge of the interconnecting pouch can be unweighted or weighted to prevent the side wall (17) and the front wall (18) to raise during use.

To attach the radiological imaging unit drape with retractable handle to surgical drape, the user should firmly attach the proximal side’s adhesive strips onto the surgical drape. When the unsterile part of the radiological equipment enter the sterile field, the user separate the interconnecting object (13), (15) on the proximal side (12) and distal side (14) respectively then expand the radiological drape to cover the unsterile part of the radiological equipment (8). The top surface of upper wall (16), the proximal side (12) and the distal side (14) will remain sterile as long as it’s not get contaminated from an unsterile object or falling. The retractable handle length can be adjusted as needed by user .When the unsterile part of radiological equipment is moved out of surgical field, the user should reengage the interconnecting objects (13), (15) together to hold the radiological drape (1) in collapse position. This manner will keep radiological imaging unit drape with retractable handle (1) sterile, not interfere with surgical team and these procedure can be repeated many times during an operation. An additional of antiseptic, anti-microorganism property or color to designate sterile and nonsterile zone can be performed to enhance the functionality of the radiological drape (1).
