Abstract
The utility model discloses a vascular anastomosis lumen internal support device which is composed of a blood vessel support piece and a handle. The blood vessel support piece is in a heart shape. The thickness of the blood vessel support piece is 0.2 millimeter to 0.8 millimeter. The length of the handle is 100 millimeters to 150 millimeters. A cross section of the handle is in a circular shape. One end of the handle is fixedly connected with the center of the bottom portion of the blood vessel support piece. An inclined angle between a centre line of the handle and a section of the bottom portion of the blood vessel support piece is 8 degrees to 15 degrees. The other end of the handle is provided with knurling. One end, provided with the knurling, of the handle is thicker than the other end, connected with the blood vessel support piece, of the handle. The vascular anastomosis lumen internal support device has the advantages of being simple in structure, reasonable in design, convenient to use and operate, good in use effect, and capable of enabling blood vessel suture surgery to be conveniently conducted, reducing difficulties of the surgery, improving speed of the surgery, protecting blood vessels, preventing the blood vessels from being damaged, thereby improving success rate of vascular anastomosis.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of vascular anastomosis tube chamber inner support device.
Background technology
Vascular anastomosis is a kind of operation form clinically.At present, having clinically needs to carry out vascular anastomosis in a lot of situations, coincide as the replantation of amputated limb, vascular accident damage, organ transplantation, internal arteriovenous fistula etc.Usually adopting two modes that disconnect vascular suture is to prick into from an outer wall that disconnects blood vessel with the pin of band wire, then pin enters the inner chamber of another blood vessel from the inner chamber of this blood vessel, prick outer wall from the inwall of another blood vessel, so repeatedly several times the blood vessel that disconnects is coincide with line.During vascular anastomosis, due to the elastical retraction of blood vessel wall after blocking blood flow, subside, tube chamber diminishes even inaccessible, front and rear wall is normal bonded to each other to be difficult for separately, easily stab in anastomosis procedures when even sewing up a vascellum laterale wall the vascular suture of offside, operation easier is large, often need to do over again, greatly slow down at the sewing process medium velocity, the bloodstream blocking time is longer.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art; a kind of vascular anastomosis tube chamber inner support device is provided; its simple in structure, reasonable in design and use easy to operate, result of use good; can facilitate the carrying out of vascular suture operation; reduce operating difficulty, improve operative speed, the protection blood vessel; anti-hemostatic tube is damaged, thereby improves the success rate of vascular anastomosis.
for achieving the above object, the technical solution adopted in the utility model is: a kind of vascular anastomosis tube chamber inner support device, it is characterized in that: formed by vessel support sheet and handle, described vessel support sheet be shaped as heart, the thickness of described vessel support sheet is 0.2mm～0.8mm, the length of described handle is 100mm～150mm, the shape of cross section of described handle is circular, one end of described handle is fixedly connected with the bottom centre of vessel support sheet, angle between the bottom tangent plane of the centrage of described handle and vessel support sheet is 8 °～15 °, the other end of described handle is provided with annular knurl, handle one end that is provided with described annular knurl is thicker than an end that is connected with the vessel support sheet.
Above-mentioned vascular anastomosis tube chamber inner support device, it is characterized in that: the angle between the bottom tangent plane of the centrage of described handle and vessel support sheet is 10 °.
