Abstract

The utility model belongs to the technical field of medical treatment treatment apparatus belongs to the medical supplies technique and specifically relates to a fibre blood vessel is cut with syringe. During the vascular operation, to the little blood vessel of sufficient bad, the vascular wall bodiness in pipe diameter little, vascular chamber, cutting with the fibre blood vessel and injuring easily the lateral wall, easily angitomy coincide, for vascular operation increase risk. The utility model discloses internal division of scissors cutting one side at the fibre blood vessel has the syringe chamber, and the injection intracavity is equipped with the syringe piston, and the syringe piston handle exposes in the open department of the scissors body, it is downthehole that syringe needle inlays the syringe needle of packing into with syringe chamber tip intercommunication, syringe needle hole site in the opposite side of cutting blade body, the syringe needle of scissors point department is good at the shearing blade. During the operation, the guide pin head is convenient for to ensure the fibre blood vessel before cuting the blood vessel and is cut at vascular intracavity before being in the scissors, can make vascular chamber sufficient, is cuting the definition that vascular in -process keeps the local operation field of vision.

Description

A kind of fibrovascular with syringe is cut

Technical field

This utility model relates to medical treatment auxiliary treatment apparatus, belongs to field of medical article technology, and specifically a kind of fibrovascular with syringe is cut。

Background technology

Fibrovascular is cut and is mainly used in vascular operation process arteriovenous incision, it is simple to the docking between blood vessel coincide。First by after syringe puncture, injecting a small amount of heparin saline in existing operation, exit syringe, then cut with fibrovascular and carry out secondary puncture, carry out angitomy。Big-and-middle arteriovenous tube chamber is big, thickness of pipe wall, cuts with fibrovascular and is relatively easy to shear, is not easy to injure offside blood vessel wall。But thin vessels little for caliber, lumen of vessels poor filling, vessel wall thickening, cutting with fibrovascular easily injures sidewall, it is not easy to angitomy coincide, risk is increased to vascular operation, the operating technology that patient is cut requires particularly severe, the damaged reparation of blood vessel wall, the scar tissue of tunica intima tube wall can be increased, can being partially formed cicatrix, narrow, blood flow is easily formed turbulent flow in the local that cicatrix is narrow, increase thrombotic risk, increase bad risk to the prognosis of patient。

Summary of the invention

The purpose of this utility model is to provide a kind of fibrovascular with syringe and cuts, it is possible to overcome the defect existing for prior art。

The technical solution of the utility model is: cuts at fibrovascular and has syringe cavity in the scissor body of side, and injecting cavity is built with syringe piston, and syringe piston handle is exposed to the open place of scissor body；Syringe needle is embedded in the syringe needle hole connected with syringe cavity end, and syringe needle hole is positioned at the opposite side of shearing blade body；Syringe needle is longer than shearing blade。

Further, described syringe needle is longer than shearing blade, refers to that syringe needle grows 1-3mm than shearing blade。

Further, syringe needle has the bending of a 10-15 degree at the syringe needle hole place stretching out shearing blade。

When the utility model has the advantages that operation, syringe needle is in the previous crops guiding of shears, it is easy to before shearing blood vessel and guarantees that fibrovascular is cut at Endovascular, lumen of vessels can be made to fill, and operation process avoids secondary puncture blood vessel, fibrovascular of the present utility model is cut and is directly punctured intravasation chamber with syringe needle, after heparin saline blood vessel filling function, take advantage of a situation and cut off blood vessel wall definition in the maintenance local operation visual field in shearing vascular process, make in operation process, because fibrovascular cuts the unnecessary local perforations caused, sew up, cicatrix, blood vessel is narrow, the risk forming local thrombus is substantially reduced, patient is physically easier to perform, increase the success rate of vascular operation。

Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in detail。

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model。

Detailed description of the invention

In figure: 1. syringe needle, 2. shearing blade, 3. syringe cavity, 4. piston rubber cap, 5. syringe piston, 6. syringe piston handle 7. vascular scissors handle, 8. spring leaf。

From fig. 1, it can be seen that this utility model is cut at fibrovascular has syringe cavity in the scissor body of side, injecting cavity is built with syringe piston, and syringe piston handle is exposed to the open place of scissor body；Syringe needle is embedded in the syringe needle hole connected with syringe cavity end, and syringe needle hole is positioned at the opposite side of shearing blade body；Syringe needle is longer than shearing blade。

Described syringe needle 1 is longer than shearing blade 2, refers to that syringe needle grows 1-3mm than shearing blade。

Syringe needle has the bending of a 10-15 degree at the syringe needle hole place stretching out shearing blade。

This utility model is stainless steel, can pass through to sterilize, Reusability。Use during vascular anastomosis during for hospital's hemodialysis。

This utility model is when performing the operation for tiny blood vessels, first cut to obtain syringe needle penetration rate of blood tube wall with fibrovascular of the present utility model, take advantage of a situation and heparin saline is pushed in thin vessels, now vascular dilation fills, blood vessel can be cut off easily, without injured blood vessel lower wall, the vascular anastomosis for next step lays a good foundation。

Finally should be noted that: above example is used for illustrating that the technical solution of the utility model is not intended to limit; embodiment is modified or portion of techniques feature carries out equivalent replacement by those skilled in the art; without deviating from the essence of technical solutions of the utility model, all should be encompassed within this utility model scope required for protection。
