Abstract
Degradable hemostatic clamp, for blood in human body in pipe hemostasis in operation.Material, with can the biomaterial of safe disposal, prevents taking-up of again performing the operation.Upper and lower clamping plate sandwich serface is arc, is interference fit, ensure that hemostatic clamp is flexible after clamping, thoroughly avoids because of vascular puncture after hemostatic clamp clamping.Two clamping plate the inners have slot to make way can reduce chucking power and material self stress.The flat clip of projection shape that the external end head of upper and lower clamping plate has the arc clip of surface groove and coordinates with its grafting in establishing respectively, in the fastening of clamping backarc folder self-aligning.The positioning convex that upper and lower clamping plate medial surface is established two detents respectively and coordinated with it, can not produce lateral sliding after ensureing clamping.Upper and lower clamping plate lateral surface is respectively equipped with upper and lower positioning handle, is convenient to operation clamping clamp and holds location, prevent hemostatic clamp from coming off from gripper clamp.And can establish for excising the cut-out head with blood vessel associated tissues.Hemostasis clamping is safe and reliable, structure is simple, easy to operate, very effectively can complete Vascular haemostasis.
Description
(-) technical field
This utility model is a kind of hemostatic clamp, for blood in human body in pipe hemostasis in surgical operation.Relate to medical treatment hemostatic device, belong to medical surgery class (А 61 В).
(2) background technology
In surgical operation conventional at present, blood in human body in pipe hemostatic technique has: hemostatic clamp, laser photocoagulation, coagulation, herbal sprinkling hemostasis, topical remedy injection hemostasis, microwave bleeding etc.According to common nonmetallic hemostatic clamp, can exist after using in human body and again dismantle problem.Can impact NMR (Nuclear Magnetic Resonance)-imaging according to metal hemostatic clamp.Laser hemostasis cost is high.The hemostasis of coagulation, herbal sprinkling, topical remedy injection hemostasis, microwave bleeding etc. are all not good to arterialness spray blood haemostatic effect.
(3) summary of the invention
The degradable hemostatic clamp that this utility model provides, exactly in order to overcome the deficiency of above-mentioned existing various Vascular haemostasis technology: the hemostatic clamp dismantled in human body that needs again to perform the operation, in-vivo metal affect the accuracy of human body nuclear magnetic resonance check, the problems such as cost is high, weak effect of stopping blooding.
The technical scheme that this utility model adopts is:
Degradable hemostatic clamp, comprising: be connected to overall train wheel bridge and lower plate, it is characterized in that:
1) all material making degradable hemostatic clamp all adopts in vivo can the biomaterial of safe disposal, can the biomaterial of safe disposal be prior art.2) inside train wheel bridge and lower plate, sandwich serface is curved surfaces, forms interference fit after clamping.And train wheel bridge and lower plate inner termination junction have slot to make way.3) external end head of train wheel bridge is provided with outside for there being the arc clip of surface groove in arc, and the external end head of lower plate is provided with the flat clip of bevelled projection shape coordinated with surface groove grafting.4) train wheel bridge medial surface is provided with the upper detent of two mutual dislocation and lower detent, and lower plate medial surface is provided with the upper positioning convex and lower positioning convex that plug with two detents respectively and coordinate.5) be provided with lower positioning handle at lower plate lateral surface, be provided with positioning handle at train wheel bridge lateral surface.
Above-mentioned degradable hemostatic clamp can be provided with inside pointed cut-out head at arc clip inner surface.
This utility model beneficial effect:
1) owing to have employed safety, degradable nonmetallic materials making hemostatic clamp, hemostatic clamp is independently degraded in vivo, does not need taking-up hemostatic clamp of again performing the operation.2) on, the hinge fraction of curved surfaces and upper lower plate link that lower plate sandwich serface is protrusion have employed flexible integrated connection and just ensure that the clamping plate of hemostatic clamp have certain elasticity, and after thoroughly avoiding hemostatic clamp clamping, blood vessel has the possibility of perforation.And slot to make way serves chucking power when reducing clamping, also reduces material self stress.3) arc clip and flat clip have the inclined-plane cooperatively interacted.When clamping, two inclined-planes slide, push, and arc clip is made a concession and produces elastic deformation, sandwich the fastening of backarc folder self-aligning.Detent and positioning convex ensure that hemostatic clamp can not produce lateral sliding after clamping.4) upper and lower clamping plate lateral surface is equipped with positioning handle, is convenient to the clamping position of degradable hemostatic clamp at gripper clamp, and prevents degradable hemostatic clamp from coming off from gripper clamp.5) the cut-out head at arc clip top can be used for excising the tissue be connected with blood vessel.6) total compared with the prior art effect is: safe degradable in human body, hemostasis clamping is safe and reliable, structure is simple, easy for operation, very effectively can complete Vascular haemostasis.

(5) detailed description of the invention
Degradable hemostatic clamp adopts can the biomaterial of safe disposal, can safe disposal in vivo.Such as use Biodegradable polymer material.See Fig. 1, Fig. 2, inside being connected to overall train wheel bridge 2 and lower plate 1, sandwich serface is respectively curved surfaces 2.1,1.1, forms interference fit 10 (see Fig. 4) after clamping.
See Fig. 1, the external end head of train wheel bridge 2 is provided with arc clip 4, has surface groove 4.1 outside arc clip in arc.See Fig. 2, the external end head of lower plate be provided with coordinate with surface groove 4.1 grafting have the flat clip 3 of the projection shape on inclined-plane 3.1.
See Fig. 1, train wheel bridge medial surface is provided with upper detent 8.1, the lower detent 8.2 of two mutual dislocation, and lower plate medial surface is provided with the upper positioning convex 7.1, the lower positioning convex 7.2 that plug with two detents respectively and coordinate.
See Fig. 2, outside lower plate, be provided with lower positioning handle 5.1 near flat clip end.Also positioning handle 5.2 is provided with near arc clip end outside train wheel bridge.Inwardly pointed cut-out 6 is had at arc clip inner surface.See Fig. 3, the junction of train wheel bridge inner termination and lower plate inner termination is provided with slot to make way 9.
During use, first according to the difference of degradable hemostatic clamp specification, select the gripper clamp matched, gripper clamp relies on two positioning handles hold and take out a degradable hemostatic clamp from being equipped with degradable hemostatic clamp support, then the operation path by establishing in advance is sent in human abdominal cavity, near the bleeding part that need stop blooding, gripper clamp is rotated between best clamping angle 60 ~ 90 degree, implement the clamping hemostasis of bleeding part.See Fig. 4, when after hemostatic clamp clamping, flat clip projection shape 3.1 inserts arc clip surface groove 4.1; Upper and lower positioning convex 7.1,7.2 inserts upper and lower detent 8.1,8.2 respectively.If hemorrhage area is large, many pieces of hemostatic clamps can be inserted successively, reach the object of stopping blooding completely.
