Abstract
The utility model relates to the technical field of medical instruments, in particular to great vessel blocking forceps with a lock catch, which can block a large vein or a large artery so as to be convenient for cutting or fitting a vessel. The great vessel blocking forceps comprise a left forceps arm (1), a right left forceps arm (2) and a connecting shaft (3), wherein rings (4) of the two forceps arms are provided with a left rack (5) and a right rack (6). The great vessel blocking forceps are characterized in that the racks are provided with the lock catch (7) formed by a nut (8) and a stud (9) or a bolt (11) and a screw hole (12); the stud (9) or the screw hole (12) is welded on the left rack (5); when the blocking forceps are buckled, the stud (9) or the bolt (11) enters an opening groove (10) on the right rack, and then the nut (8) on the stud (9) or the bolt (11) in the screw hole (12) can be screwed for locking the two racks. The great vessel blocking forceps has convenient use, can effectively prevent the loosening of the left and the right racks, so that the great vessel blocking forceps can block the blood flow of the large vein or the large artery, thereby being beneficial for successful operation.
Description
Technical field
This utility model relates to technical field of medical instruments, is that a kind of large vein or large artery trunks blocked is convenient to blood vessel is cut or the large vascular blocking forceps of the button with lock that coincide.
Background technology
Clinically, when liver transplantation or some surgical operation, must firmly clamp with blocking blood flow large vein or large artery trunks blood vessel with large vascular blocking forceps earlier, again trunk be cut or the row anastomosis.Said large vascular blocking forceps by about the coupling two tong arms and a connecting axle form, article two, tong arm is that fulcrum links to each other and is X-shaped and intersects with the connecting axle, tong arm is divided into forearm and postbrachium two parts, left and right sides forearm is provided with the groove section, the groove section is convexly curved usually, also can be straight shape or other shapes, and its forward surface is provided with complementary groove, can be chimeric mutually when closing up, so that anti-hemostatic tube slippage during interlock; The tail end of postbrachium is a finger ring, is used to be inserted in finger and operates, and the forward surface of the left and right sides postbrachium before the finger ring is provided with a pair of tooth bar, and the forward surface of left and right sides tooth bar is provided with the hook of mutual coupling, fixes by the interlock of blocking-up pincers left and right sides hook, prevents that the blocking-up pincers from unclamping.But in operating process, may be because certain be beyond thought former thereby getting loose of left and right sides tooth bar take place, to such an extent as to the patient is because of fierce hemorrhage generation shock or the death of moment, for this reason, usually adopt silk thread that left and right sides finger ring is pinioned at present,, but thisly often need two people operation with silk thread binding, fastening, knotting and dismounting silk thread with anti-loose, not only operation inconvenience, and increased the time of performing the operation.
Summary of the invention
The purpose of this utility model provides a kind of easy to operate, large vascular blocking forceps of preventing the button with lock that left and right sides tooth bar gets loose.
This utility model is the above-mentioned improvement of large vascular blocking forceps commonly used clinically, by about the coupling two tong arms and a connecting axle form, article two, tong arm is that fulcrum links to each other and is X-shaped and intersects with the connecting axle, tong arm is divided into forearm and postbrachium two parts, left and right sides forearm is provided with the groove section, and its forward surface is provided with complementary groove; The tail end of left and right sides postbrachium is a finger ring, be provided with a pair of tooth bar in opposite directions before the finger ring, the forward surface of left and right sides tooth bar is provided with the hook of mutual coupling, it is characterized in that left and right sides tooth bar is provided with snap close, said snap close is made up of nut and double-screw bolt or bolt and screw, nut and double-screw bolt snap close, its double-screw bolt one end is fixedly welded on the middle position of left tooth bar free-end hook, be provided with the longitudinal opening groove of a width and double-screw bolt external diameter coupling in the corresponding middle position of right tooth bar, double-screw bolt enters this groove, nut is screwed into from the top of this double-screw bolt, with two tooth bar lockings; Bolt and screw snap close, its screw are located at the middle position of left tooth bar free-end hook, and bolt is inserted in the screw, be provided with the longitudinal opening groove of a width and bolt external diameter coupling in the corresponding middle position of right tooth bar, bolt enters this groove, tights a bolt in screw, with two tooth bar lockings.The nuts and bolt handle is the butterfly type.
During use, this utility model is clamped blood vessel with left and right sides forearm routinely, double-screw bolt on left tooth bar or bolt enter the open slot of right tooth bar to appropriate depth, and fastening nut or bolt can be fixed left and right sides tooth bar interlock and can not get loose.
This utility model is simple in structure, and is easy to use, only needs people's operation to get final product, can effectively prevent getting loose of left and right sides tooth bar, guarantee large vascular blocking forceps to large vein or large artery trunks blood vessel blocking blood flow, help carrying out smoothly of trunk incision or row anastomosis, shortened the time of operation.
