Abstract
The utility model mainly relates to the medical appliance, in particular to a medical instrument for surgery clinic, and more particularly relates to a hole puncher for medium and small artery blood vessels. The hole puncher comprises a hole puncher body (3); a dowel steel (5) is arranged inside the hole puncher body (3); the lower end of the dowel steel (5) is provided with a punching head (1); a cavity die (2) is arranged between the hole puncher body (5) and the dowel steel (5); a handle (7) is hinged on the dowel steel (5), and the handle is connected with the hole puncher body (3) through a knighthead (8); and a spring lamination (9) is arranged below the handle (7). The utility model has reasonable design, simple structure and convenient use, and can keep the continuity of blood vessels for the lateral vascular anastomosis at the blood vessel end; the utility model has an oblong caliber, and the major axis is along the longitudinal axis of the major axis, thereby the blood vessel is damaged little, and the blood vessel can not be easily folded after being oversewed; the axis is eccentric, and only a pinhole is needed to be sheared when punching; and the endarterium formed in one step is smooth and is suitable for blood vessels which is longer than 3 mm.
Description
Technical field:
This utility model relates generally to medical apparatus and instruments, relates in particular to the medical surgical clinical surgical instrument.
Background technology:
At present, in clinical operation, coincideing of action vein blood vessel occupied bigger workload.The formula of row end-to-side anastomosis now internal arteriovenous fistula, the general employing of renal transplantation are manually cut the hole on blood vessel, the effectively shape of control hole and size can not be controlled the polishing in cross section, influence the identical quality of blood vessel behind the inner film injury.Cut that the hole is excessive easily causes major injury to blood vessel, cause arteries to give a discount after coincideing, influence the blood flow that far-end blood supply and anastomotic stoma are passed through; It is too small to cut the hole, and the blood flow that anastomotic stoma is passed through can not satisfy dialysis or supply the demand of kidney.When card punch is applied to the internal arteriovenous fistula operation, can keep arterial vascular seriality can shorten the free length of tremulous pulse simultaneously.
Existing punching apparatus, punching is medium and small blood vessel for circle is not suitable for, and medium and small blood vessel punching is then caused major injury to blood vessel, causes arteries to give a discount after coincideing.Generally it is only applicable to trunk, and the impetus height is difficult for finishing accurate operation simultaneously.
The utility model content:
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of medium and small arteries card punch is provided.To improve the identical quality of operation medium vessels.
The purpose of this utility model can be by realizing by the following technical solutions: a kind of medium and small arteries card punch, include punching body (3), its main feature is: be provided with dowel steel (5) in punching body (3), be provided with punching head (1) in the lower end of dowel steel (5), between punching body (3) and dowel steel (5), be provided with die (2); On dowel steel (5), be hinged with handle (7), handle (7) is linked to each other with punching body (3) by support bar (8); The below of handle (7) is provided with spring leaf (9).
Described medium and small arteries card punch, the upper end of dowel steel (5) is provided with spring (10); The inner chamber of described die (2) is oval.Major diameter is parallel with the blood vessel major axis, and is not only little to the damage of blood vessel, and the postoperative blood vessel is difficult for giving a discount.
Described medium and small arteries card punch, the centrage of the centrage of described punching head (1) and dowel steel (5) is not on the same line.Eccentric shaft only needs at artery scissors one aperture during punching.
The described described die of medium and small arteries card punch (2) links to each other with dowel steel (5) by connecting pin (4).
The beneficial effects of the utility model are: this utility model is reasonable in design, and is simple in structure, easy to use.The seriality that can keep blood vessel to the blood vessel end-to-side anastomosis; Oval bore, major axis is along the blood vessel longitudinal axis, and is little to blood vessel injury, sews up the back blood vessel and should not give a discount; Eccentric shaft only needs during punching at artery scissors one aperture; Once-forming endarterium polishing, and this type of patient's tunica intima mostly has pathological changes in various degree; Be applicable to the blood vessel that 3mm is above.
Description of drawings:
Fig. 1 looks cross-sectional schematic for master of the present utility model;
Fig. 2 is the C-C cross-sectional schematic of Fig. 1.
The specific embodiment:
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing:
During use, at artery scissors one aperture, to punch and 1 fill in the hole, handle 7 by the A position to the B position, by support bar 8, swivel pin 6 drive dowel steels 5, and then drive punching 1 action bounces back, and finishing punches moves, get back to the A position then under the effect of reseting spring leaf 9, punching 1 is stretched out and is finished the action of moving back waste material.
