Definitions

  • the invention relates generally to a surgical glove and to a hand mould for making such a glove. More specifically, the invention concerns a surgical glove which may be worn by a surgical doctor for an extended period of time while performing surgery.
  • a typical surgical glove In the course of a surgical procedure, a typical surgical glove is worn while the doctor is performing a surgery in a surgery room. A typical surgical glove can be worn from as little as 10 minutes to more than 15 hours to complete a procedure. In the course of a long surgery, many pairs of gloves are changed for cleanliness, leaving the surgical room for rest or food, good sterile practice, etc. Nevertheless the amount of time when the gloves are worn on the hands is long enough to cause hand fatigue. Such length of time puts a physical stress on the hands of the surgeon as the gloves are designed to be worn tight without slack or loose folds in order to maximize dexterity and sensitivity.
  • GB-A-2148094 discloses a plastic glove made by dipping a hand-shaped form which comprises an index finger portion, a middle finger portion, a third finger portion and a little finger portion, each defining a curved line extending from the knuckle portion to the fingertip portion with an angle of curvature of from 35° to 90°. Preferably there is an included angle of less than 90° between a first tangent touching the curved line at the fingertip portion and a second tangent touching on the back side surface of the hand portion.
  • WO-A-98/14079 discloses an anatomically-accurate surgical glove manufactured from an elastomeric material, having an enlarged thumb ball portion and independently curved fingers.
  • the invention provides a surgical glove hand mould comprising a set of digits, consisting of thumb and index, middle, ring and little fingers, wherein the digits are disposed in positions consistent with that of a human hand when holding a surgical implement.
  • each of the digits includes at least one major bend.
  • the digits of the mould are to copy the one major bend (Bend 1 ) of the proximal-middle joint for the index, middle, ring and little fingers.
  • the one major bend (Bend 1 ) occurs at the metacarpal-proximal joint.
  • the location of Bend 1 of the fingers and thumb is defined as the point of the first bend measured from the base of the finger crouch as a percentage of the total length of the straightened finger from finger crouch to fingertip.
  • An angle of bend (a) of the first bend of the fingers is defined as the acute angle formed by the intersection of a first line formed along the proximal bone and a second line formed along the middle bone.
  • An angle of bend (a) of the first bend for the thumb is defined as the acute angle formed by the intersection of a first line formed along the metacarpal bone and a second line formed along the proximal bone.
  • each of the digits includes two bends.
  • the locations of Bend 1 are as per Table 1 herein.
  • the digits of the mould are to copy the two bends of the proximal-middle joint and middle-distal bone joint for the index, middle, ring and little fingers.
  • the first bend (Bend 1 ) occurs at the metacarpal-proximal joint and the second bend (Bend 2 ) occurs at the proximal-distal joint.
  • the location of Bend 2 of the fingers and thumb is defined as the point of the second bend measured from the base of the finger crouch as a percentage of the total length of the straightened finger from finger crouch to fingertip.
  • An angle of bend (b) of the second bend of the fingers is defined as the acute angle formed by the intersection of a first line formed along the middle bone and a second line formed along the distal bone.
  • An angle of bend (b) of the second bend is defined as the acute angle formed by the intersection of a first line formed along the proximal bone and a second line formed along the distal bone.
  • the locations of Bend 1 and Bend 2 are as per Table 2 herein.
  • the thumb and index finger are relatively disposed to define a gap between them of approximately 1 cm.
  • the invention provides a surgical glove formed using the mould according to the first aspect.
  • each of the digits of the surgical glove includes at least one major bend.
  • a first bend of the fingers is located at a proximal-middle joint.
  • a first bend of the thumb is located at a metacarpal-proximal joint.
  • each of the digits of the surgical glove includes two bends.
  • a first bend of the fingers is located at a proximal-middle joint and the second bend of the fingers is located at a middle-distal joint.
  • a first bend of the thumb is located at a metacarpal-proximal joint and the second bend of the thumb is located at a proximal-distal joint.
  • the glove mould or former may be made of ceramic, porcelain, aluminium, cast metal, polymers, or polymer-based material.
  • the glove is formed by dipping the mould into a bath of liquid latex, which is then dried and vulcanized by heating to a temperature sufficient to crosslink the latex molecules.
  • the gloves are stripped from the mould by hand or machine, individually in a two-dimensional movement.
  • the surgical glove may be made of any of natural latex, polyurethane, synthetic latex, polyisoprene latex, chloroprene latex, acrylonitrile butadiene based latex, and blends or combinations of these latex, PVC, SEBS, SIS and variants or combinations of these materials with any other latex(s) mentioned above.
  • the present invention seeks to provide a solution to the hand fatigue problems by introducing a particular and one or more distinctive bends in the fingers of the glove.
  • the strain on a surgeon's hands is caused by the fact that the surgeon's hands are not posed in a way which resembles the pose of the hands when in rested position. In most cases, the surgeon will be holding a tool of some sort and so will have his hands almost closed.
  • the surgeon must exert continual force on the glove to grasp the tool.
  • the present invention overcomes this limitation by creating a mould that, when used to make gloves, creates stress and slack in such a way that the natural shape of the glove when worn will approximate the pose of the surgeon's hands while manipulating a surgical implement.
  • the present invention thus reduces tension in the glove by using dimensional proportions that match closely the hand position most commonly occupied by a surgeon while retaining the tightness which provides improved sensitivity and dexterity.
  • the present invention is based on the idea of specific articulation required during the process of surgery including positioning of one or more bends in the former used to produce the gloves.
  • FIG. 1 is shows a prior art glove mould having a slight curvature
  • FIG. 2 shows the bones of a human hand
  • FIG. 3 shows the natural position of a surgeon's hand that is already in a casual folder disposition.
  • FIG. 4 shows the natural position of a surgeon's hand in a grip position when holding a surgical implement
  • FIG. 5 shows the measurement of the location of Bend 1 and Bend 2 in the form of percentage (%) on the finger joints.
  • FIG. 6 shows the first embodiment in which the mould has one major bend to copy
  • FIG. 7 shows the first embodiment in which the mould has two major bends to copy.
  • the material of the glove can be made softer to reduce the elastic stress being exerted when deformed/stretched.
  • a material that is too elastic will not function as a skin tight glove, easily stretching and will be unable to return to shape quickly.
  • the present invention proposes to make a glove that conforms to the disposition of the hand of the surgeon most of the time when he is actually wearing the glove and at work on a surgical procedure.
  • the surgeon's hands can be in several poses: hands down by his side (very seldom), hands lifted to waist length with hands forward (very often) and using this same pose with the hands gripping something, be it a scalpel, tool, etc. (most common).
  • the invention is thus to address this position of the hands that is very often the position of the surgeon's hands when in surgery.
  • FIG. 1 Most surgical gloves commonly available to the public come in the shape of slightly curved fingers glove as illustrated by FIG. 1 .
  • the glove as illustrated in FIG. 1 does not address the finger stress as experienced by the surgeon and hence does not make effective glove.
  • FIG. 2 illustrates the four major bones of a human hand namely the metacarpal, proximal, middle and distal bones of the fingers.
  • the invention is to make a glove that is shaped like a hand that is already in a casual folded disposition, as shown in FIG. 3 . As described above, this is also the pose of the hand which a surgeon uses the most when working. Further observation is that the surgeon's hand is not totally closed where the index finger is touching the thumb, but more often in a position that is holding something of about 1 cm in size between his index finger and thumb.
  • FIG. 4 thus provides a shape of glove that closely matches this arrangement of fingers-palm-thumb relative positions in which the hand is in a grip position.
  • FIGS. 3 and 4 A typical range of angles of the fingers in the various positions are as follows, with FIGS. 3 and 4 illustrating how these angles can be measured.
  • the angles vary depending on the ratio of the finger bones and also according to gender.
  • the invention takes into account the ratio of lengths of the fingers and the angles to produce a shape that is as close to the shape of the hand at those positions.
  • the first bend is at the metacarpal-proximal joint.
  • the second bend is at the proximal-middle joint, and the third bend is at the middle-distal digit joint.
  • the two major bends occur at the proximal-middle joint and the middle-distal joint.
  • the thumb does not have a middle bone.
  • the two major bends occur at the metacarpal-proximal joint and the proximal-distal joint.
  • the locations of the bends are related and relative to the finger lengths.
  • surgical gloves are made to sizes of 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5 and 10.
  • finger lengths that can be designed and made without the need for compliance to any standards, international, regional or national.
  • the only criterion is to attempt to match the general demographic anatomical size, with certain regions of the world preferring shorter fingers in a glove and others preferring generally longer fingers in a glove. This also depends on the size of the glove as described above.
  • the only parameter to which any international, regional or national standards apply is the width of the palm that is to match the sizes.
  • the relevant standards are ASTM 3577, EN 455 and ISO 11232. These sizes again do not have any fixed standard finger lengths.
  • FIGS. 5 to 7 show how the location of Bend 1 represented by point X and the location of Bend 2 represented by point Y on the finger digits are measured in the form of percentage (%) of the total length of the straightened finger from finger crouch to fingertip respectively.
  • the locations of Bends 1 and 2 for the five fingers are measured from the base of the finger crouches (knuckle of the respective fingers) to the respective point of bends when the fingers are in straightened positions as seen from FIG. 5 . 100% thus corresponds to the fingertip location and 0% to the location of the knuckle.
  • the first embodiment of the invention resides in a mould that has one major bend (Bend 1 ) in the digits as illustrated in FIG. 6 at the point X. This is to copy the one major bend (Bend 1 ) of the proximal-middle joint for the index, middle, ring and little fingers. For the thumb, the one major bend (Bend 1 ) occurs at the metacarpal-proximal joint.
  • FIG. 6 illustrates how the parameters in Table 1 of the first bend in the form of location of Bend 1 (X) and angle of bend (a) are measured.
  • the range of locations of Bend 1 (X) in percentage (%) for the different parts of the fingers as tabulated in Table 1 are based on general demographic anatomical sizes.
  • the angle of bend (a) of the first bend for the index, middle, ring and little fingers is defined as the acute angle formed by the intersection of a first line formed along the proximal bone and a second line formed along the middle bone.
  • the angle of bend (a) of the first bend for the thumb is defined as the acute angle formed by the intersection of a first line formed along the metacarpal bone and a second line formed along the proximal bone.
  • the second embodiment of the invention resides in a mould that has two major bends in the digits as illustrated in FIG. 7 . This is to copy the two bends of the proximal-middle joint and middle-distal bone joint for the index, middle, ring and little fingers. For the thumb, the first bend (Bend 1 ) occurs at the metacarpal-proximal joint and the second bend (Bend 2 ) occurs at the proximal-distal joint.
  • the aggregate of the two bends from the metacarpal line will be the defining angle as measured as angle of bend (c). See Table 2.
  • FIG. 7 illustrates how the parameters as tabulated in Table 2 of the two bends in the form of location of Bend 1 represented by point X and angle of bend (a) and location of Bend 2 represented by point Y and angle of bend (b) are measured. The measurement of the angle of the aggregate angle of bend (c) is also shown.
  • the range of locations of Bend 1 (X) and Bend 2 in percentage (%) for the different parts of the fingers as tabulated in Table 2 are based on general demographic anatomical sizes.
  • the angle of bend (b) of the second bend for the index, middle, ring and little fingers is defined as the acute angle formed by the intersection of a first line formed along the middle bone and a second line formed along the distal bone.
  • the angle of bend (c) is the combined aggregate angles of bend (a) and bend (b).
  • the angle of bend (b) of the second bend for the thumb is defined as the acute angle formed by the intersection of a first line formed along the proximal bone and a second line formed along the distal bone.
  • the angle of bend (c) is the combined aggregate angles of bend (a) and bend (b).
