摘要:
A connector assembly having a male member, a female member and a retainer for releasably securing the male member and the female member. The retainer has inner retainer arms for simultaneously engaging the male member and an interior portion of the female member, and an outer retainer flange for engaging an outer portion of the female member.

The invention relates to a medical gripping and/or retaining instrument, in particular a needle holder, comprising a handle (2) with two hand grips (2a, 2b) and a retainer piece (3) with two jaw pieces (3a, 3b), operated by the handle (2). According to the invention, a gripping and/or retaining instrument may be achieved, whereby at least one part of a jaw piece (3a) of the retainer piece (3) is mounted such as to rotate about the longitudinal axis of the jaw piece (3a) or to be adjusted in the direction of the longitudinal axis of the jaw piece (3a), relative to at least one other jaw piece (3b) cooperating with said jaw piece (3a).

A device (20) or restricting removal from the end of a tubular member (2) of a collar (4) or the like located on the tubular member (2) and a method using the device (20), the device (20) comprising an axially extending portion (22) for engagement in the end of the tubular member (2) and a radially outwardly extending portion (28) which in use is located outside the end of the tubular member (2) and which extends radially outwardly to a greater diameter than the internal diameter of the collar (4), thereby to restrict removal of the collar (4) from the end of the tubular member (2). In addition there is provided (20) for sealing the axially facing end of a tubular member (2), the device (20) comprising an axially extending portion (22) for engagement in the tubular member (2), a radially outwardly extending portion (28) which in use is located outside the tubular member (2) and a sealing means (48) for sealing between the radially outwardly extending portion (28) and the axially facing end (54) of the tubular member (2).
摘要:
A method and apparatus for performing a minimally invasive ( i . e ., with the wound developed under an incision being substantially the same size as the incision throughout the depth of the wound) total hip arthroplasty. A rasp handle is disclosed, comprising an insertion member having engagement means for selectively engaging a cable, and whereby said cable is affixable to a rasp. Also disclosed is a provisional femoral neck which may have a spring biased locking piston in a hollow cylindrical body, or which may have a guide surface which is piloted to a mate on a provisional femoral stem.
摘要:
A pliers (10) which has a pair of heads (12,14) with these heads (12,14) being reversible so that one head is in a usage position the other head is in a stowage position located between a pair of handles (32,34). Each handle (32,34) of the pair of handles is pivotable about one hundred sixty degrees with the handles (32,34) to be located in juxtaposition in both the usage position and the stowage position. Each handle including a convex surface (50,52) and a concave surface (46,54) and also each handle including a pommel (56). Each of the convex surfaces and each of the concave surfaces and each of the pommels (56) function to ergonomically assist in grasping of the handles (32,34).
摘要:
A method and apparatus for performing minimally invasive total hip arthroplasty are disclosed. Through an anterior incision (44), the femoral neck (60) is severed using an osteotomy guide (78), the acetabulum (54) is prepared, and an acetabular cup is inserted. An awl (106) is provided to locate a posterior incision (46) aligned with the axis of the femoral shaft (62) through which the femur is prepared using a tubular posterior retractor (122), a reamer (151) and a rasp (204) with a lockable handle (212), to which a provisional femoral head and a selectively lockable provisional neck (222) are attached. The rasp is then removed and the femoral inplant (238) is inserted in a bag (242) to keep it clean. Procedures performed through one incision may be observed through the other
摘要:
Die Erfindung betrifft eine Spannbacke (10) für ein Backenfutter, mit einem Grundkörper (12) aus Metall, auf den eine Hartmetall-Spannfläche aufgelötet ist. Um einen Verzug der Spannbacke durch das Hartlöten zu vermeiden, schlägt die Erfindung vor, die Spannfläche (18) mit Hartmetall-Partikeln (22) anstatt einer großflächigen Hartmetall-Platte zu versehen.
摘要:
Pipe wrench with two shanks each with a toothed jaw at an angle to the shank, the shanks connected at a joint and one shank translatable relative to the joint to adjust the distance between the jaws, with the tooth tips on each jaw located in a plane, and the height and pitch distance between teeth monotonously increasing from a small value for teeth nearest to the shank up to a larger value for teeth farthest from the shank, the increase being at least 25 %.
摘要:
The method consists in cutting out the outlines (11) of a series of blanks in lengths of shaping sections (10) of variable thickness whereof the cross-section corresponds at least to one cross-section of the blanks. The invention is useful for making clamp jaws and elements of various pliers.
