Abstract
The utility model relates to the technical field of medical appliances, in particular to a pair of intramedullary pin holding forceps, which comprises a left forcep arm and a right forcep arm. A left jaw is arranged on the front end of the left forcep arm. A left forcep ring is arranged at the rear end of the left forcep arm. A right jaw is arranged on the front end of the right forcep arm. A right forcep ring is arranged at the rear end of the right forcep arm. The left forcep arm and the right forcep arm are articulated through a hinged shaft in a cross way. The forceps are characterized in that a transverse groove and a longitudinal groove are respectively arranged on the contact surface of the left jaw and the right jaw; and the transverse groove is communicated with the longitudinal groove through an arched groove. Because of using the structure, the forceps disclosed by the utility model have the advantages of rational structure, no slip, short operation time, high working efficiency and the like.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of broach gripper clamp.
Background technology
At present, when the knochenbruch patient being carried out knochenbruch and taking over art, normally broach is inserted in patient's the medullary cavity clinically; Pass fracture line, boring and penetrate pinning on skeleton then can and be fixed together the knochenbruch butt joint; At last the end of broach is bent the nail device with the broach bending, to prevent broach at the medullary cavity intrinsic displacement, in the time will taking out broach with intramedullary pin; Then hook broach rear end bending part with needle holder and outwards extract out, this needle holder comprises left clamp arm and right clamp arm, and the left clamp arm front end is provided with left jaw; The rear end is provided with left side pincers ring, and the right clamp arm front end is provided with right jaw, and the rear end is provided with right pincers ring; Left clamp arm and right clamp arm are through the hinge cross-articulation, and the contact surface of left jaw and right jaw is provided with horizontal teeth, and its deficiency is: when clamping bone intramedullary needle; Because the horizontal teeth on the jaw are consistent with the wrap direction of broach end, the needle holder clamping does not live when causing outwards extracting broach out, and skidding is serious; Increased doctor's labor intensity, prolonged operating time, inefficiency.
Summary of the invention
The purpose of this utility model is the deficiency that solves above-mentioned prior art, a kind of rational in infrastructure, non-slip, operating time Duan Duan is provided, the broach clamper of high efficiency.
This utility model solves the technical scheme that its technical problem adopted:
A kind of broach gripper clamp comprises left clamp arm and right forearm, and the left clamp arm front end is provided with left jaw; The rear end is provided with left side pincers ring, and the right clamp arm front end is provided with right jaw, and the rear end is provided with right pincers ring; Left clamp arm and right clamp arm is characterized in that being respectively equipped with transverse concave groove and longitudinal fluting on left jaw and the right jaw contact surface through the hinge cross-articulation, and transverse concave groove is connected with longitudinal fluting through arc groove; Be beneficial to block the bending part of broach tail end, be convenient to outwards extract out broach.
This utility model has rational in infrastructure, non-slip, operating time Duan Duan, advantages such as work efficiency height owing to adopt said structure.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Fig. 2 is the cutaway view of A-A among Fig. 1.
Fig. 3 is the partial schematic diagram of right jaw.
Reference numeral: left clamp arm 1, right forearm 2, left jaw 3, left side pincers ring 4, right jaw 5, right pincers ring 6, hinge 7, transverse concave groove 8, longitudinal fluting 9, arc groove 10.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further specified:
Shown in accompanying drawing, a kind of broach gripper clamp comprises left clamp arm 1 and right forearm 2; Left clamp arm 1 front end is provided with left jaw 3, and the rear end is provided with left side pincers ring 4, and right clamp arm 2 front ends are provided with right jaw 5; The rear end is provided with right pincers ring 6; Left clamp arm 1 and right clamp arm 2 is characterized in that being respectively equipped with transverse concave groove 8 and longitudinal fluting 9 on left jaw 3 and right jaw 5 contact surfaces through hinge 7 cross-articulation, and transverse concave groove 8 is connected with longitudinal fluting 9 through arc groove 10; Be beneficial to block the bending part of broach tail end, be convenient to outwards extract out broach.
When using this utility model to take out the broach in the medullary cavity clinically; Finger places left side pincers ring 4 and right pincers ring 6; Clamp the bending part of broach tail end with transverse concave groove 8, longitudinal fluting 9 and arc groove 10 on right jaw 5 corresponding surfaces of left jaw of left clamp arm 1 front end 3 and right clamp arm 2 front ends, firmly outwards extract broach out and get final product.
This utility model has rational in infrastructure, non-slip, operating time Duan Duan, advantages such as work efficiency height owing to adopt said structure.
