Abstract
The utility model discloses a novel vascular clamp used for blocking blood stream at small blood vessels with an anastomosis method, wherein clamp holders and a tail-end handle are integrated into a whole and a clamp shaft is articulated at the middle part of the clamp holders and the tail-end handle. A clamping surface relative to the two clamp holders is a jaw and the two tail-end handles are connected by a spring. The section of the clamp holder from the clamp shaft to the ends takes the shape of an arc, with a curvature of 1/4 to 3/8 and a chord length of 13mm to 16mm. The direction of thearc is in the same plane with the clamping surface of the jaw. The vascular clamp can reduce steps of anastomosis at small blood vessels so as to increase the speed and the success rate of anastomosis, improve clinic prognosis and can be widely applied to clinic microsurgical operation and used in the anastomosis at the abdominal blood vessels of an animal organ transplantation model, with relatively good social and economic benefits.
Description
Technical field
This utility model relates to a kind of surgical operating instrument, particularly a kind of novel vascular folder that is used for vascular anastomosis temporary interruption blood flow.
Background technology
In the little blood vessel end-to-side anastomosis operation of clinical microsurgery,, need block two ends blood vessel to be coincide respectively with blocking blood flow with two micro-vascular clamps for the little blood vessel that will need to coincide separates fully with surrounding tissue.Existing micro-blood vessel accompanies the pair of straight clamp holder, operating procedure complexity in clamping blood vessel and the process of separating surrounding tissue, instrumentation quantity is more, cause tissue injury and hemorrhage easily, if the field of operation vessel branch is more for a long time, then must use many to vascular clamp with the whole ligation of these branches, it is bad the field of operation blood supply to take place after some important branch vessel ligation, influence histoorgan and reflux, even cause operative failure.For the operator, repeatedly repeat these steps for a long time at microscopically, can make the operative doctor dysphoria, not only consuming time, consumption power, and the fineness and the success rate of operation of influence operation.
The utility model content
In order to overcome the deficiencies in the prior art, this utility model provides a kind of novel vascular folder that is used for little blood vessel end-to-side anastomosis blocking blood flow, solve and use when carrying out little blood vessel end-to-side anastomosis that traditional vascular clamp step complexity, quantity are many, consuming time, effort, the bad problem of field of operation blood supply.
The technical scheme that its technical problem that solves this utility model adopts is:
A kind of novel vascular folder that is used for little blood vessel end-to-side anastomosis blocking blood flow, clamp holder and end hand grip are connected as a single entity, the folder axle is hinged on the two medium position, the clamping face that two clamp holders are relative is a jaw, connect spring between two end hand grips, it is characterized in that: described clamp holder is curved arc shape from the folder axle to the end, crooked radian is 1/4～3/8, chord length is 13mm～16mm, and curved arc direction and jaw clamping face are at grade.
The jaw clamping face of described clamp holder can be the plane.
The length ratio of described clamp holder and end hand grip can be 3: 1～and 7: 1.
The beneficial effects of the utility model are as follows:
Compare traditional micro-vascular clamp, clamp holder of the present utility model is the arc clamp holder that specific arc and chord length are arranged, clamp holder can be provided by blood vessel two ends simultaneously that provide the side to coincide, the arc lower edge of clamp holder collatoral vessel also capable of blocking, and all sides that need not thoroughly free blood vessel and the identical district of ligation are propped up, so obviously reduced operating procedure, have improved identical speed, increase success rate of operation, reduced the working strength of operative doctor.
After using this utility model, the blood vessel that does not need when carrying out little blood vessel end-to-side anastomosis to provide the side to coincide is all free, the subbranch that does not also need ligation side Zhi Huiliu only needs the connective tissue in blood vessel the place ahead that will be to be coincide to separate, and directly uses this vascular clamp that art open country clearly can be provided.
This utility model is simple in structure, the appearance dexterity, can simplify the step of little blood vessel end-to-side anastomosis, reduce instrumentation quantity in the operation, improved the fineness of identical speed and operation, the success rate of increase coincideing is improved clinical prognosis, overcome use that traditional micro-vascular clamp step complexity, quantity are many, consuming time, effort, the bad shortcoming of field of operation blood supply.Both can be widely used in the clinical microsurgery, also can when the end-to-side anastomosis of toy abdomen organ transplantation model blood vessel, use.

Fig. 1 is a perspective view of the present utility model.
Fig. 2 is the sketch map of the transverse section of arc clamp holder.
Fig. 3 is the sketch map that this utility model cooperates with blood vessel.
Reference numeral: 1-clamp holder, 2-folder axle, 3-end hand grip, 4-spring.
The specific embodiment
Embodiment is referring to shown in Figure 1, this novel vascular folder that is used for little blood vessel end-to-side anastomosis blocking blood flow, clamp holder 1 and end hand grip 3 are connected as a single entity, folder axle 2 is hinged on the two medium position, and two clamp holders, 1 relative clamping face is a jaw, connects spring 4 between two end hand grips, clamp holder 1 is curved arc shape from the folder axle to the end, crooked radian b is 1/4～3/8, and chord length a is 13mm～16mm, and curved arc direction and jaw clamping face are at grade.Referring to Fig. 2, the high c of the transverse section of clamp holder 1 is 1.5mm, and wide d is 1mm.
The jaw clamping face of described clamp holder can be the plane, and described clamp holder 1 is 3: 1～7: 1 with the length ratio of end hand grip 3.
Referring to Fig. 3, there is spring 4 that resilient clamp power is provided in the middle of two end hand grips 3, clamp holder and handle are connected as a single entity, and be fixing by folder axle 2.The size of chucking power is by spring 4 control, and chucking power is moderate, both blocking blood flows fully, the unlikely again tunica intima that crushes.Clamp holder 1 is provided by blood vessel two ends simultaneously that provide the side to coincide, i.e. A among the figure, B two places, the arc lower edge of clamp holder 1 is also blocked the collatoral vessel of backflow, i.e. C place among the figure, the blood vessel that does not need when using the capable end-to-side anastomosis of present embodiment to provide the side to coincide is all free, the subbranch that does not also need ligation side Zhi Huiliu only needs the connective tissue in blood vessel the place ahead that will be to be coincide to separate, and directly uses this vascular clamp that surgical field of view clearly can be provided.
