Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] Reference Figs. 1 to 3 This utility model provides a medical glove for precise, three-dimensional molding during hand defect repair or reconstruction. The glove body includes a hand portion and finger portions. Each finger portion has five finger sleeves corresponding to a finger. The back of each finger sleeve faces the back of the finger, the palm side faces the fingertip, the left side faces the left side of the finger, the right side faces the right side of the finger, and the front end faces the fingertip. The surface is provided with grid lines. The finger sleeve is provided with a first perforation, a second perforation, a third perforation, and a fourth perforation. The first perforation is located on the back side of the finger sleeve, between the back side of the finger sleeve corresponding to the distal interphalangeal joint of the finger and the nail root. The second perforation is located in the middle of the front end of the finger sleeve. The third perforation is located on the left side of the finger sleeve, and the fourth perforation is located on the right side of the finger sleeve. The third and fourth perforations are located at the distal interphalangeal joint of the finger sleeve. The main body of the glove is transparent.
[0026] In this embodiment, the main body of the glove is relatively hard so that it can maintain the three-dimensional shape of the hand and fingers in a natural state. The glove material is also required to have relatively poor elasticity so that there will be no artificial pulling during the molding process, which would cause inaccurate molding.
[0027] When encountering patients with varying degrees of missing palms, backs of hands, or fingers due to various reasons, the patient's hand is placed inside the glove body 1. Because the glove body 1 is transparent, the surgeon can see the missing area through it and trace the patient's missing area on the outer surface of the glove body 1. Therefore, the traced missing area is precise, and then it is cut off with scissors. Because the glove is relatively stiff, it maintains the three-dimensional shape of the hand and fingers in its natural state, resulting in a three-dimensional template. The cut missing area is placed on the toes or other parts of the body, and tissue from those areas is removed using a scalpel and transferred to the missing finger area.
[0028] In this embodiment, the glove body comprises, from the inside out, an anti-adhesive layer, an adhesive layer, and a printed layer. Grid lines 15 are printed on the printed layer, and the adhesive layer bonds the anti-adhesive layer and the printed layer. In this embodiment, the anti-adhesive layer, adhesive layer, and printed layer are stacked together. When marking the defective area, the anti-adhesive layer and the printed layer are bonded together by the adhesive layer. Before placing the cut glove body 1 used to mark the defective area on the toes, the surgeon can peel off the anti-adhesive layer, allowing the adhesive layer to adhere directly to the surface of the toes. This prevents the glove template from slipping during the shaping process, allowing the surgeon to directly outline the required skin flap shape on the toes based on the glove template, improving surgical precision.
[0029] Due to injury, the skin at the fingertip may be longer than the remaining phalanx. This excess skin may then adhere haphazardly to the fingertip. Alternatively, during the surgical incision design before finger reconstruction, surgeons can use sutures to pull the haphazardly adhered skin to maximize its utilization. This allows the skin on the dorsal, palmar, and lateral sides of the finger to adhere to the inner layer of the glove, maximizing and three-dimensionally utilizing the remaining skin. If necessary, a second perforation (12) can be inserted longitudinally along the phalanx axis from the center of the fingertip to maintain the distal interphalangeal joints straight, or even both the proximal and distal interphalangeal joints straight, preventing inaccurate impressions due to finger bending during molding. The shape of the skin and soft tissue defects, the location of the finger bone defects, and the location of the extensor / flexor tendon defects are marked using a surgical marker. After the patient's finger is removed from the glove body 1, the glove body 1 is cut with scissors to obtain the glove body 1 with the defective part. The anti-adhesive layer of the glove 1 is peeled off, and the glove body 1 with the defective part is pasted onto the toe or other parts. The required shape is drawn on the toe or other parts with a surgical marker, and the required skin flap is cut according to the routine surgery.
[0030] Reference Fig. 3 As an example, the printed layer also includes a finger bone outline pattern 16 and a ruler; the finger bone outline pattern 16, the ruler, and the grid lines 15 are different colors. Taking the finger bone outline pattern 16 as an example, for ease of observation... Fig. 3 Remove the grid lines 15 on the glove body 1, leaving only the finger bone outline pattern 16 and the ruler on the glove body 1. In this embodiment, the finger bone outline and ruler can also be set on the printing layer. The finger bone outline specifically includes the proximal phalanx, the middle phalanx, and the distal phalanx.
[0031] The grid lines 15 allow surgeons to quickly calculate the area of the missing part. The finger bone pattern and the ruler printed on it help surgeons to accurately design and control the length of bone to be removed and the precise position of the joint when reconstructing the finger interphalangeal joint.
[0032] When needed, the finger bone outline pattern printed on the glove base layer can precisely design the position of the reconstructed finger joints and the required bone length, so that the reconstructed finger is as close as possible to the natural finger, and at the same time makes the reconstructed finger more matched and coordinated with other fingers when they move.
[0033] If the surgery requires harvesting a toe joint or flexor / extensor tendons, first, attach the impression glove (without removing the adhesive layer) to the corresponding position on the dorsal side of the second toe, based on the required bone length, joint position, and flexor / extensor tendon length. Mark the required bone length, joint position, and flexor / extensor tendon length using a surgical marker. Then, remove the adhesive layer from the impression glove (this prevents the glove template from slipping during the outlining of the skin and soft tissue shape). Following standard surgical practice, attach the impression glove to the corresponding position on the first toe and trace the required skin and soft tissue shape. After the design is complete, continue the surgical procedure as usual.
[0034] If the surgery does not require harvesting toe joints or flexor tendons, but only skin, soft tissue, or nails from the toes, simply remove the anti-adhesive layer of the impression-taking glove (this is to prevent the glove template from slipping during the process of outlining the shape of the skin and soft tissue after it is applied). Following standard surgical practice, attach the impression-taking glove to the corresponding position of the first or second toe and trace the desired shape of the skin and soft tissue. After the design is completed, continue the surgical procedure as usual.
[0035] After adjustment, draw the missing area on the glove body, mark the location of bone and flexor tendon defects, and then cut out the three-dimensional missing area of the finger.
[0036] Each finger is provided with a first perforation 11, a second perforation 12, a third perforation 13, and a fourth perforation 14 to address situations where a patient is injured in a specific finger or multiple fingers are injured simultaneously.
[0037] In this embodiment, the first, second, third, and fourth perforations can be set by the surgeon according to actual needs. In other embodiments, this embodiment can be used in cases of single finger loss or multiple finger loss simultaneously.
[0038] As an example, the first perforation 11, the second perforation 12, the third perforation 13 and the fourth perforation 14 are all round holes, and the diameter of the first perforation 11, the second perforation 12, the third perforation 13 and the fourth perforation 14 is 0.8-1.2mm.
[0039] More specifically, the first perforation, the second perforation, the third perforation, and the fourth perforation are all round holes, and the diameter of the first perforation, the second perforation, the third perforation, and the fourth perforation is 1.0 mm.
[0040] In other embodiments, the diameters of the first perforation, the second perforation, the third perforation, and the fourth perforation are any one of 0.8 mm, 0.9 mm, 1.1 mm, and 1.2 mm.
[0041] As an example, the grid lines crisscross to divide the space into multiple square grids, each of the grid lines 15 being a square, with a side length of 1-5 mm. In this embodiment, the side length of each grid in the grid lines 15 is 1 mm. The square grid lines 15 allow surgeons to quickly calculate the defect area.
[0042] In other embodiments, the side length of all the square grids can be one of 2mm, 3mm, 4mm and 5mm.
[0043] In one embodiment, the medical glove for precise, three-dimensional molding during hand defect repair or reconstruction further includes an outer glove layer superimposed on the printed layer; the outer glove layer includes a bone layer, on which finger bone outline patterns 16 and scales 17 are printed, and the colors of the finger bone outline patterns 16, the scales 17 and the grid lines on the bone layer are different.
[0044] In addition to the above embodiment, different colored finger bone outline patterns are printed on the printing layer. In this embodiment, a bone layer and a ruler layer are added to the outer surface of the glove body with grid lines 15 printed on it. A ruler 17 is printed on the ruler layer and extends along the extension direction of the finger sleeve. The length of the severed finger can be quickly determined by the ruler 17. The colors of the finger bone outline pattern 16 on the bone layer, the ruler 17, and the grid lines 15 are all different.
[0045] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
