Abstract
The utility model discloses a pair of hepatic portal blocking forceps which is medical equipment. The utility model comprises left and right half forceps which are connected by a shaft, wherein, the front half parts of the two half forceps form arc bending. The utility model is characterized in that the shapes of a left and a right forceps heads are of a flat head type; a pressure spring is arranged between two handles of the back half parts of the left and the right forceps; an adjusting bolt is arranged on the pressure spring, and the adjusting bolt is riveted on the right handle. The utility model has the effects that when the hepatic portal blocking operation is operated, the pair of forceps can be used for effectively and completely blocking the blood flow of a hepatic portal, and the damage of the tissue structure of the hepatic portal can not be caused. Simultaneously, the utility model has the advantages of convenient disinfection, compact structure and convenient operation.
Description
This utility model relates to medical apparatus and instruments, particularly a kind of hepatic portal occlusion pincers that are applicable to that liver part resection operation is used.
At present, implement in half liver, lobe of the liver, the disconnected excision of liver in hepatocarcinoma, hepatic cyst, hepatic haemangioma, when vascular inflow occlusion blood supplies, the rubber compression cord that use are finished more, and do not have a kind of complete hepatic portal occlusion apparatus, the shortcoming of rubber compression cord: the one, and rubber strap can not high-temperature sterilization, the 2nd, elasticity is difficult for grasping, it is incomplete easily to form hepatic portal occlusion, or causes hepatic portal to organize pipe damage, directly influences operation technique.
It is convenient that the purpose of this utility model provides a kind of sterilization, simple to operate, effectively the hepatic portal occlusion of vascular inflow occlusion blood flow pincers.
Task of the present utility model is to realize like this, it comprises about two half pincers that connect with axle, the first half of two and half pincers is the arc bending, it is characterized in that: the shape of left and right sides binding clip is tack, about stage clip is arranged in the middle of partly clamping latter half of two handles, there is one to regulate bolt on the stage clip, regulates the bolt riveting leftward on the handle.
The utlity model has following effect: when doing the hepatic portal occlusion operation, use these pincers vascular inflow occlusion blood flow effectively fully, can not cause the damage of hepatic portal organizational structure, simultaneously, sterilization is convenient, and compact conformation is convenient to operation.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a right view of the present utility model.
Among the figure: 1. binding clip 2. connecting axles 3. handles 4. stage clips 5. nuts 6. bolts
Further describe embodiment of the present utility model in conjunction with above accompanying drawing.
As shown in Figure 1 and Figure 2, connect with connecting axle 3 between left and right two and half pincers, the shape of binding clip 1 is tack, the first half of two and half pincers is convexly curved, in the middle of latter half of two handles 3 of two and half pincers, stage clip 4 is arranged, an adjusting nut 6 is arranged on the stage clip 4, and the adjusting nut 6 on the stage clip 4 passes through bolt 5 rivetings on right handles.When operation, push handle 3, the resistance that overcomes stage clip 4 makes the handle closure, and binding clip opens; During release handle pressure, under the effect of stage clip 4, handle is along with opening the binding clip auto-closing.Can carry out hepatic portal occlusion, easy to operate.When too small or excessive, can regulate the nut on the stage clip 4 as needs binding clip tension force.
