Embodiment

Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, Obviously, described embodiment is only the utility model part of the embodiment, rather than whole embodiments.Based on this practicality Embodiment in new, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made Example is applied, belongs to the scope of the utility model protection.

As illustrated in fig. 1 and 2, there is provided a kind of anatomic reduction pincers, including：Handle 1, reset pressing plate 2 and positioning bracket 3, positioning Bracket 3 is arranged on the back side of the handle 1, for supporting the handle 1, plays a part of positioning and Auxiliary support so that whole Body structure is more stable.

The reset pressing plate 2 includes：Shell fragment 4, needle tubing 5 and connecting rod 6.Described one end of shell fragment 4 is fixed on the end of handle 1 End, the other end tilt to the side away from the handle 1, and shell fragment 4 described in pressable makes it unclamp shell fragment 4 close to the handle 1 Afterwards, shell fragment 4 recovers to original position, to be achieved in the reset function of anatomic reduction pincers automatically.Described one end of connecting rod 6 and the shell fragment 4 is be hinged, and end is be hinged with the needle tubing 5, when pressing, unclamping the shell fragment 4, drives the connecting rod 6 to act, so that institute Needle tubing 5 is stated to move reciprocatingly.

The tip of handle 1 opens up elongate slots, and the end of elongate slots sets restraining position ring block 7, also set up in the elongate slots There is nook closing member 8, the needle tubing 5 is arranged in the elongate slots, and is moved reciprocatingly in the elongate slots, and the nook closing member 8 runs through The needle tubing 5 is simultaneously fixed in the elongate slots, and the end of the nook closing member 8 opens up a breach 9.

Needle tubing 5 moves stopping under the impetus of the connecting rod 6 along main shaft between position and working position, i.e. such as Fig. 2 It is shown, the reset pressing plate 2 is pressed, the needle tubing 5 reaches working position, the breach 9 on the nook closing member 8 covered, so as to press from both sides Firmly tissue.As shown in figure 1, after shell fragment 4 are unclamped, under elastic force effect, the reset pressing plate 2 recovers to original position, so as to band The dynamic needle tubing 5 reaches position of stopping, and now the breach 9 exposes.The surface of the shell fragment 4 and the connecting rod 6 is provided with anti-skidding Rib, during sampling, rely primarily on thumb and apply pressure to shell fragment 4 and connecting rod 6, anti-sliding rib can prevent finger slippage, increase safety Coefficient.

As shown in figure 3, positioning bracket 3 includes：Pedestal 31, spring 32 and arc 33.The quantity of pedestal 31 is 1 to 3, A spring 32 is respectively provided with each pedestal 31, the end of each spring 32 is respectively provided with an arc 33, and pedestal 31 is arranged on The back side of the handle 1, the end face of arc 33 set spongy layer 34, avoid scraping injured tissue.Positioning bracket 4 play positioning and it is auxiliary The effect of support is helped, when being clamped using anatomic reduction, can will position the frame of bracket 3 on skin, because spring 32 has elastic force, so The direction of needle tubing 5 and nook closing member 8 can arbitrarily be adjusted.

The back side of handle 1 is additionally provided with handheld board 10, and the handheld board 10 is perpendicular to the handle 1, the handheld board 10 Side is fixed on the back side of handle 1, and the edge of opposite side forms ripple glaze.In use, whole palm when held handheld board 10 With handle 1, as long as thumb is had an effect, the pressing reset pressing plate 2, can preferably control gripping dynamics.

The front of the handle 1 is additionally provided with spacing preiection 11, avoids excessively pressing from resetting pressing plate 2, so as to damage needle tubing 5。

The end of handle 1 is additionally provided with hook 12, is easy to store.
