Abstract
The utility model, relating to medical appliance technical area, is a hemostat for blocking hepatic veins at hepatic operations. The main difference between the device and the current hemostat is as follows. The front end of the forearm (1) is embowed. At the occlusal surface of the right and the left arms a longitudinal bar-shaped groove is provided in the one arm and a bar-shaped protrusion matching to the groove is equipped in the other arm. The bar-shaped protrusion can right be inserted into the groove while the two are clutched, which can effectively block the blood flow and bring no harm to the vessel wall. The post arm (2) is bended to the opposite direction of the forearm, which will not block operation viewing. The hemostat is applicable for overturn and manipulation at hepatic operations and can effectively prevent hepatic veins bleeding or aeroembolism. The device can also be used for blocking blood at other operations.
Description
Technical field
This utility model relates to technical field of medical instruments, is used for the mosquito forceps of hepatic vein blocking-up when being a kind of liver surgery.
Background technology
The risk of operation on liver is massive hemorrhage, air embolism in the operation, and massive hemorrhage, air embolism often occur in the hepatic vein place of second hepatic portal.Therefore must block the hepatic vein blood flow during operation on liver.Surgical hemostasis is used mosquito forceps usually clinically.Common mosquito forceps is the boundary with the rotating shaft screw in cross point, and divide forearm and postbrachium two parts: forearm is shorter, about the occlusal surface of two arms be provided with little tooth, rely on its interlock hemostasis; Postbrachium is the hemostasis clamp holder, longer, about the tail end of two arms be the finger ring cover, operate for being inserted in finger, the inboard of left and right sides postbrachium respectively is provided with a latch bar, two latch bars in opposite directions and complementary make it continue to clamp blood vessel to reach the hemostatic purpose so that fix forearm by the interlock between the left and right arms latch bar.Yet the moulding of this mosquito forceps is not suitable for blocking the hepatic vein blood flow, and reason is that forearm is too short, postbrachium is oversize, before and after arm type linearly, the upset of liver and operation when being unfavorable for performing the operation, and easily cause the damage of the slim blood vessel wall of hepatic vein during the little tooth interlock of left and right sides forearm.At present, also be not specifically designed to the vascular occlusion clamp of hepatic vein blocking-up both at home and abroad.
Summary of the invention
This utility model provides a kind of mosquito forceps that is applicable to the hepatic vein blocking-up, and it is the improvement to existing mosquito forceps.One of improving is that front end with forearm extends into arc-shaped bend, is convenient to trigger hepatic vein when making operation; Two of improvement changes the occlusal surface of two arms about forearm between groove and the projection chimeric by the interlock of little between cog, promptly wherein an arm is provided with a strip groove longitudinally, another arm is then correspondingly established a strip bulge longitudinally, during two arm interlocks, strip bulge just is embedded in the groove, this mode is blocked hepatic vein, can not only effectively stop blooding, and can not injure blood vessel wall; Three of improvement is to shorten postbrachium, and changes the linear postbrachium postbrachium of a bending into, and the direction of the bending just in time direction with the forearm arc-shaped bend is opposite, but both flexible operating when performing the operation like this can prevent from again to obstruct the view.This utility model is through zoopery and clinic trial, and is easy to operate, haemostatic effect good, can arbitrarily adjust the position folder and close hepatic vein, do not hinder the visual field, is difficult for causing injury of hepatic vein.This utility model also can be used as the blocking-up of other position blood vessel.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Now in conjunction with the accompanying drawings and embodiments, this utility model is described in detail.
This utility model is the boundary with cross point rotating shaft screw 3, is divided into forearm 1 and postbrachium 2 two parts.The front end of forearm 1 is convexly curved, about on the occlusal surface of two arms, one arm is provided with a strip groove 1.1 longitudinally, another arm correspondingly is provided with a strip bulge longitudinally, the length degree of the length and width of strip groove 1.1, the degree of depth and strip bulge is complementary, about during two arm interlocks, strip bulge just is embedded in the strip groove 1.1; Postbrachium about 2 two arms respectively are provided with finger ring cover 2.1 and latch bar 2.2, and complementation is so that block in opposite directions by interlock for the latch bar flank of tooth of left and right arms, and left and right sides postbrachium has a bending point 2.3, and as boundary's postbrachium bending hypsokinesis, the hypsokinesis direction is opposite with forearm arc-shaped bend direction.
Embodiment one
Top external diameter 2mm when this utility model forearm 1 left and right arms closes up, root external diameter 5mm, forearm length overall 5cm, the partly long 2cm of arc-shaped bend wherein, radian is 30 °, the strip groove 1.1 long 3.5cm of an arm, wide 0.6mm, dark 0.5mm.The corresponding coupling of the length of the strip bulge on another arm with it.Postbrachium 2 length overall 6cm, bending point 2.3 is 3cm to the length between the rotating shaft screw 3, and bending hypsokinesis angle is 30 °, and finger ring overlaps 2.1 internal diameter 2.4cm, external diameter 3cm.Latch bar 2.2 long 8mm, wide 3mm has 4 latches.
Embodiment two
This utility model forearm 1 length overall 6.5cm, the long 2.5cm of arc-shaped bend wherein, radian is the strip groove 1.1 long 4cm of 45 ° of one arm, the corresponding coupling with it of the length of the strip bulge on another arm.Postbrachium 2 length overall 7cm, bending point 2.3 to the length between the rotating shaft screw 3 is 4cm, and 4 latches are arranged.All the other are with embodiment one.
Embodiment three
This utility model forearm 1 length overall 8cm, the long 3cm of arc-shaped bend wherein, radian is 60 °, the strip groove 1.1 long 5cm of an arm, the corresponding coupling with it of the length of the strip bulge on another arm.Postbrachium 2 length overall 8cm, bending point 2.3 to the length between the rotating shaft screw 3 is 5cm, and 4 latches are arranged.All the other are with embodiment one.
