Abstract
The utility model relates to an adjustable vascular clamp which comprises an upper arm and a lower arm. The upper arm and the lower arm are connected through a hinge. The inner surface of the upper arm and the inner surface of the lower arm are respectively provided with a layer of soft materials, and lock catch structures which are matched with each other are arranged on the head portion of the upper arm and the head portion of the lower arm. The lock catch structures comprise positioning convex teeth which are arranged on the head portion of one of the upper arm and the lower arm and positioning concave teeth which are arranged at the corresponding position on the other arm, the positioning convex teeth are made of elastic materials, and at least two positioning convex teeth and/or positioning concave teeth are arranged. The structure is used, due to the fact that the layers of soft materials are arranged on the inner surface of the upper arm and the inner surface of the lower arm, the vascular clamp has certain buffer to the pressure of blood vessels, necessary pressure can be kept, the pressure is guaranteed to be not two high, and the edges of the soft materials can not damage the walls of the blood vessels. Due to the fact that at least two positioning concave teeth and positioning convex teeth are arranged, the closing degree of the vascular clamp is made to be adjustable, and different demands can be met.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially is used for the vascular clamp of closed blood vessel in the surgical operation.
Background technology
Surgical operation is often used vascular clamp and is come blocking blood flow and close up two blood vessel ends, and the metallic blood vessels that use press from both sides more at present, and the metallic blood vessel folder is to the lasting clamp of blood vessel, and the vascular damaged that causes has caused generally to be noted.The direct vascular compression wall of metal blade, chucking power is often greater than the required minimum pressure of blocking blood flow, the direct vascular compression in metal blade edge that hardness is large, produce the cutting force at right angle, the damage that these have all increased blood vessel wall facts have proved, uses for a long time vascular clamp will cause larger damage to tunica intima, after blood flow is logical again, often because causing local thrombus, inner film injury forms.The contact of metal blade is inhomogeneous, causes some site pressure excessive, and some site pressure is too small, occurs leaking.In addition, in different situations, the pressure that needs vascular clamp to produce is also different, and it is very inconvenient that existing vascular clamp is regulated pressure.
The utility model content
The technical problems to be solved in the utility model provide a kind of can be to blood vessel wall injury, vascular clamp that pressure is even and adjustable.
For solving the problems of the technologies described above, adjustable vascular clamp of the present utility model comprises upper arm and underarm, and upper arm and underarm are connected through the hinge, and the inner surface of described upper arm and underarm arranges one deck flexible material, and the head of upper arm and underarm has the buckle structure that cooperatively interacts.
Described buckle structure comprises the location double wedge of the head that is arranged on an arm in the underarm, and the recessed tooth in the location that arranges on the opposite position of another arm, and described location double wedge is elastomeric material.
Described location double wedge and/or locate recessed tooth twice are set at least.
Described upper arm and underarm be shaped as circular arc.
The cross section of the flexible material on described upper arm and the underarm is the semicircle waveform of mutual interlock.
After adopting such structure, because upper underarm inner surface arranges one deck flexible material, vascular clamp has certain buffering to the pressure of blood vessel, both can keep necessary pressure, and guaranteed pressure is not too large, and the edge of flexible material can be to the blood vessel wall injury; Locate the recessed tooth of recessed tooth and location owing to be provided with at least twice, so that the closed degree scalable of vascular clamp adapts to different requirements; Upper arm and underarm be shaped as circular arc, can make the flexible material of vascular clamp middle part thicker, can keep with good elasticity; The cross section of the flexible material on upper arm and the underarm is the semicircle waveform of mutual interlock, can make blood vessel more firm with contacting of vascular clamp, avoids leaking, and also avoids occuring simultaneously length travel.
Description of drawings
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
Fig. 1 is the structural representation of adjustable vascular clamp of the present utility model.
Fig. 2 is that adjustable vascular clamp of the present utility model is along the longitudinal sectional drawing of A-A line among Fig. 1.
The specific embodiment
Adjustable vascular clamp of the present utility model, comprise upper arm 1 and underarm 2, upper arm 1 is connected with underarm by hinge 3 connections, the inner surface of upper arm 1 and underarm 2 arranges one deck flexible material 4, the head of upper arm 1 and underarm 2 has the buckle structure that cooperatively interacts, buckle structure comprises the location double wedge 5 of the head that is arranged on upper arm, with the recessed tooth 6 in location that arranges on the opposite position of underarm 2, location double wedge 5 is elastomeric material, the recessed tooth 6 of location double wedge 5 and location arranges twice, upper arm 1 and underarm 2 be shaped as circular arc, the cross section of the flexible material on upper arm 1 and the underarm 2 is the semicircle waveform of mutual interlock.
The above, only be to preferred embodiment of the present utility model, be not that this utility model is done other forms of restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equal variation.Every this utility model scheme content that do not break away from, all drops in protection scope of the present invention any simple modification, equivalent variations and remodeling that above embodiment does according to technical spirit of the present invention.
Claims (5)
