Abstract
The utility model provides a pair of reposition forceps for metacarpi and phalanxes. The pair of reposition forceps comprises clamping parts, handheld parts and middle parts, wherein the clamping parts are used for clamping the metacarpi and the phalanxes, the handheld parts are used for controlling the opening-and-closing angle of the clamping parts, and the middle parts are connected with the clamping parts and the handheld parts. The clamping parts comprise two oppositely-arranged arc-shaped clamping pieces. The radians of the arc shapes of the arc-shaped clamping pieces correspond to the radians of the metacarpi and the phalanxes. By the adoption of the structure, the radians of the arc shapes of the arc-shaped clamping pieces are designed according to the radians of the appearances of the metacarpi and the phalanxes, therefore, the continuous, firm and pressurized reposition roles in surrounding the metacarpi or the phalanxes are played, anatomical reposition of the fractured metacarpi and the fractured phalanxes can be achieved, and transposition can not easily occur again after the reposition.

Background technology
In the prior art, usually need to carry out internal fixation operation of cutting and resetting behind the hand Phalangeal fracture, so that the phalanges of fracture resets, and often will use fracture resetting tongs.And mostly reduction forceps of the prior art is the reduction forceps for long bone of limbs, does not have special hand metacarpal bone, phalanges reduction forceps.In addition, clinician's great majority adopt tissue forceps or vascular forceps to reset.Use when tissue forceps or vascular forceps are used for the clamp fine tissue originally, often easily slippage also is not easy to reach stable when clamp metacarpal bone, phalanges, often need lasting the exerting oneself of operator, easily cause fatigue, can not make fractures to reach effectively resets, thereby affects the healing of fracture end.
The utility model content
When utilizing tissue forceps or vascular forceps that metacarpal-phalangeal is resetted in the prior art in order to solve, what exist can not reach effective, lasting clamp and the defective that resets, the utility model proposes a kind of Metacarpophalangeal reduction forceps that is specifically designed to, comprise for the described Metacarpophalangeal clamping part of clamp, be used for controlling the Handheld Division of described clamping part folding angle and the pars intermedia that connects described clamping part and described Handheld Division, wherein, described clamping part comprises two arc holding pieces that are oppositely arranged, and the radian of the arc of described arc holding piece is corresponding with described Metacarpophalangeal radian.
Preferably, the arc length of described two arc holding pieces is respectively 1/4 of described metacarpal-phalangeal circumference.
Adopt the reduction forceps of the present utility model of said structure, the radian of the arc of arc holding piece is that the radian according to metacarpal bone, phalanges profile designs, encircle metacarpal bone or phalanges thereby play, reach reset response lasting, firm, pressurization, make the metacarpal-phalangeal of fracture can reach anatomical reduction, be not easy to be shifted again after resetting.
Further, described Handheld Division comprises the first hand-held ring and the second hand-held ring, described pars intermedia comprises the first tong arm and the second tong arm, the described first hand-held ring is connected with an end of the first tong arm, the described second hand-held ring is connected with an end of the second tong arm, and described the first tong arm and the second tong arm are hinged, and forms the pincers neck in the articulated section, the other end of described the first tong arm and the second tong arm is connected with described two arc holding pieces respectively.
Especially, described the first tong arm is connected with one of them described arc holding piece by the first semi arch binding clip, and described the second tong arm is connected with another described arc holding piece by the second circular arc binding clip.
The design of this circular arc binding clip utilizes the ring-type pressurization, makes Metacarpophalangeal clamping more stable.
Preferably, described tong arm with a end that described hand-held ring is connected near, be provided be used to the clamp-buckle that locks described clamping part opening angle, described clamp-buckle is respectively equipped with the dentalation that cooperatively interacts for being located at respectively two strip bulges on described the first tong arm and the second tong arm on described two strip bulges.
Being designed with of clamp-buckle is beneficial to be adjusted and the fixed clamp dynamics.
Preferably, the described first hand-held ring and the second hand-held ring are for circular.This circular hand-held ring is convenient to hold finger.Certainly, hand-held ring can also adopt those skilled in the art thinkable other suitable shapes, for example oval or be fit to the structure of finger shape.
" metacarpal-phalangeal " in this utility model refers to metacarpal bone and the phalanges of hand.
" connection " in this utility model comprises and is fixedly connected with flexible connection, removably connect, and also comprises connection between integrated two positions etc.
Description of drawings
Fig. 1 is the structural representation that the phalanges reduction forceps clamp of this utility model one specific embodiment phalanges.
Fig. 2 is the A-A schematic cross-section among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.For the person of ordinary skill in the field, to the detailed description of the present utility model, above-mentioned purpose of the present utility model, feature and advantage will be apparent.
The reduction forceps that is used for metacarpal-phalangeal 10 in a kind of embodiment of this utility model as illustrated in fig. 1 and 2, comprise clamping part 20 for clamp metacarpal-phalangeal 10, be used for the Handheld Division 21 of folding angle of control clamping part 20 and the pars intermedia 22 that connects clamping part 20 and Handheld Division 20, wherein, clamping part 20 comprises two arc holding pieces 201 that are oppositely arranged, the radian of the arc of arc holding piece 201 is corresponding with the radian of metacarpal-phalangeal 10, and the arc length of two arc holding pieces 201 is respectively 1/4 (with reference to Fig. 2) of metacarpal-phalangeal 10 circumference.Metacarpophalangeal radian is generally smaller, and reduction forceps of the present utility model according to Metacarpophalangeal radian design, therefore can more firmly pick up metacarpal-phalangeal specially, is convenient to the carrying out of reattachment surgery.In addition, the design of 1/4 radian is so that reduction forceps of the present utility model also goes for the metacarpal-phalangeal of multiple radian scope.
