Technical Field
The utility model relates to the technical field of surgical instruments, especially, relate to an outward turning formula carotid intimal denudation fixer.
Background
When the existing vascular surgery and neurosurgery are used for the outward turning type carotid intimal stripping operation of carotid stenosis, in the process of stripping the intimal of a blood vessel, an assistant can only use two hands to use the blood vessel forceps to match with a main knife doctor to turn the intimal of the blood vessel outward to strip, when the intimal position of the blood vessel is deep, the operation visual field is not clear, the operation time is long, the operation difficulty is increased, the intimal cannot be completely stripped, and the probability of postoperative cerebral infarction is increased.
Therefore, at present, the technicians in the field need to design an eversion type carotid endarterium denudation fixator, which shortens the operation time and reduces the risk of cerebral infarction after operation.
SUMMERY OF THE UTILITY MODEL
The utility model provides an outward turning type carotid intima stripping fixer, which solves the problems that in the prior art, the outward turning type carotid intima stripping operation time is long and the intima can not be stripped completely.
The technical scheme of the utility model as follows:
an everting carotid intimal stripping fixator comprising:
the blood vessel puncture device comprises a first main body and a second main body, wherein the first main body comprises a cylinder body and a cylinder cavity positioned on the cylinder body, and the cylinder cavity is used for blood vessel puncture; and
the second main body is connected to one end of the cylinder body.
The both ends of barrel are the fillet, the barrel cross-section is the ring form.
The two ends of the second main body are respectively provided with a bending part and a handheld part, the bending parts are connected with the barrel, and the lowest surface of the barrel is higher than the highest surface of the bending parts.
The second main body is a rod body.
The diameter of the connecting surface of the second main body and the handheld part is larger than that of the connecting surface of the second main body and the return bending part.
The cylinder body is of a frustum structure.
The utility model discloses a theory of operation and beneficial effect do:
the utility model relates to an outward turning formula carotid intimal denudation fixer, include: the blood vessel puncture device comprises a first main body and a second main body, wherein the first main body comprises a cylinder body and a cylinder cavity positioned on the cylinder body, and the cylinder cavity is used for blood vessel puncture; and the second main body is connected to one end of the barrel body, when a transection manipulation is adopted in carotid intimal stripping operation, an assistant holds the second main body by hand, the cut blood vessel passes through the barrel cavity and then turns outwards, the blood vessel is supported on the barrel body, the stripping operation is conveniently carried out, the stripping is completed in the section, the blood vessel continues to turn outwards for operation, a doctor can conveniently complete stripping, intimal fragments are avoided being remained, and the problems that in the prior art, the time of the outward-turning carotid intimal stripping operation is long, and the intimal cannot be completely stripped are solved.

FIG. 2 is an enlarged view of portion A shown in FIG. 1;
FIG. 3 is a schematic structural view of the present invention in example 2;
FIG. 4 is an enlarged view of the portion B shown in FIG. 3;
in the figure: 1. the hand-held type disposable syringe comprises a first main body, 2, a barrel body, 3, a barrel cavity, 4, a second main body, 5, a return bending part, 6 and a hand-held part.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive work, are related to the scope of the present invention.
Example 1
As shown in fig. 1 to 2, an everting carotid intimal denudation fixator includes: the blood vessel puncture preventing device comprises a first main body 1, wherein the first main body 1 comprises a cylinder body 2 and a cylinder cavity 3 positioned on the cylinder body 2, the cross section of the cylinder body 2 is circular, and the cylinder cavity 3 is used for blood vessels to pass through; and a second body 4 connected to one end of the cylinder 2.
In the embodiment, when the carotid intimal stripping operation adopts a crosscutting method, the assistant holds the second main body 4 by hand, the cut blood vessel passes through the cylinder cavity 3, then the blood vessel is turned outwards, the intimal leaks out, and the blood vessel is supported on the cylinder body 2, so that the stripping operation is conveniently carried out, the stripping is finished at the section, the blood vessel is continuously turned outwards, the stripping operation is carried out, a doctor can conveniently complete stripping, the residual intimal debris is avoided, the operation time is greatly shortened, and the occurrence of cerebral infarction events is avoided.
As shown in fig. 2, both ends of the cylinder 2 are rounded.
In this embodiment, the both ends of barrel 2 set up to the fillet, avoid causing scratch, damage to the blood vessel to influence the postoperative and resume, avoid patient to take place other dangers.
As shown in fig. 1 to 2, the second body 4 is provided with a bent portion 5 and a holding portion 6 at both ends thereof, the bent portion 5 is connected to the barrel 2, and the lowest surface of the barrel 2 is higher than the highest surface of the bent portion 5.
In this embodiment, the return bend 5 facilitates downward movement of the everted blood vessels, preventing accumulation of the everted blood vessels due to their long length.
As shown in fig. 1 to 2, the diameter of the connecting surface of the second body 4 and the hand-held portion 6 is larger than the diameter of the connecting surface of the second body 4 and the bent-back portion 5.
In this embodiment, the diameter of the second main body 4 is reduced at a position close to the blood vessel, so as to avoid the visual field obstruction of the blood vessel position, and to expose the blood vessel intima to the visual field of the doctor to the maximum extent.
Example 2
As shown in fig. 3 to 4, the cylinder 2 has a frustum-shaped structure, and the rest of the structure is the same as that of example 1.
