Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in fig. 1, fig. 2 and fig. 3, the utility model provides a novel hemostatic clip, including hinge 1 to and set up in at least one single clamp 2 of hinge, the single clamp includes two clamp 3 and torsional spring (not shown in the figure), the clamp includes the clamping part 4 of front end, the splenium 5 of pressing of rear end and lie in the articulated portion 6 between splenium and the clamping part, the correspondence of articulated portion both sides is equipped with the hinge hole, the hinge passes the hinge hole 7 of two clamps, the hinge hole of one of them clamp is round hole 8, the hinge hole of another clamp is fan-shaped hole 9, the cross sectional shape and the fan-shaped hole of hinge cooperate.

The hemostatic clamp provided in the embodiment of the present application may be a single clamp, or may be formed by two single clamps arranged side by side on a hinge shaft (as shown in fig. 1). Two clamp bodies and the torsional spring of single clamp link together through the hinge, specifically, the articulated portion of two clamp bodies is provided with the centre gripping hole at bilateral symmetry, and the articulated portion of one of them clamp body can inlay in the articulated portion of another clamp body inboard, and the centre gripping hole position of two clamp bodies corresponds each other, and the torsional spring is placed in two clamp body inboards simultaneously, and the centre gripping hole is aligned in the middle part of torsional spring for the hinge can pass the hinge hole and the torsional spring middle part of two clamp bodies in proper order, realizes the connection to two clamp bodies and torsional spring. Two torque arms of the torsion spring can be attached to the inner side of the pressing part of the clamp body to provide elasticity for the hemostatic clamp.

The clamping part of the clamp body is used for clamping blood vessels or tissues, the hinge part is used for hinging the clamp body and the hinge shaft, and the pressing part of the clamp body is used for holding and pressing the hemostatic clamp by a doctor.

As shown in fig. 4 and 5, the hinge hole of one clamp body is a sector hole, and the cross-sectional shape of the hinge shaft is matched with the sector hole, so that the clamp body and the hinge shaft are relatively fixedly connected; the hinge hole of the other clamp body is a round hole, so that the clamp body can freely rotate along the hinge shaft, when the hemostatic clamp is used and the clamping part of the clamp body is pressed, the clamp body can freely rotate along the hinge shaft, the clamping part of the hemostatic clamp is opened or closed, and the other clamp body and the hinge shaft are kept relatively fixed. When the hemostatic clamp is a double-clamp type, the two single clamps have a clamp body relatively fixed with the hinge shaft, so that the single clamp can not twist along the hinge shaft, the twisting deformation of the clamped closed blood vessel caused by the rotation of the single clamp along the hinge shaft is avoided, the operation of a doctor is facilitated, and the operation effect is effectively ensured.

Optionally, the scallops are semi-circular.

As shown in fig. 4, 5, 6 and 7, the outer end of the pressing portion of the clip body is provided with a protruding portion 10, and the front end of the pressing portion is provided with an arc-shaped concave portion 11. The tail end of the pressing part is sequentially provided with an arc-shaped concave part and a convex part, so that the convex part is convenient for a doctor to hold and is convenient for operation.

Optionally, the middle of the protrusion is provided with a holding groove 12.

In practical use, the hemostatic clamp is often used in conjunction with various devices (such as clip applier, titanium clip, forceps, etc.) for applying pressure to the pressing portion of the hemostatic clamp, so that the clamping portion of the hemostatic clamp is opened under the action of the pressure. In order to facilitate the matching of the hemostatic clamp with the clip applier, the titanium clamp, the forceps and other instruments, a clamping groove is formed in the middle of the protruding portion.

Fig. 8, 9 and 10 show the surgical straight-reverse vertical forceps 13, the laparoscopic minimally invasive clip applier 14 and the micro platform forceps 15 respectively in cooperation with the hemostatic clip provided in the embodiments of the present application. The surgical direct-reverse vertical forceps, the laparoscopic minimally invasive forceps and the tips of the micro-platform forceps for clamping can clamp the hemostatic clamp through the clamping grooves. Due to the arrangement of the clamping groove, the clamping of the clip applier, the titanium clip, the forceps and the like to the hemostatic clip is stable, and the operation is convenient. Therefore, the hemostatic clamp provided by the embodiment of the application can be used for microsurgery, minimally invasive surgery and general surgery.

As shown in fig. 6, a drawing hole 16 is formed at the rear end of the pressing portion of at least one clip body, and the clip body is connected with a drawing wire through the drawing hole. Before an open or minimally invasive operation, a traction wire penetrates into the traction hole, so that the hemostatic clamp can be conveniently and safely taken out after the operation, and the hemostatic clamp can be prevented from being difficultly found after falling into the abdominal cavity. The traction line which is penetrated in the traction hole can lead the suture line of the surgical operation to be convenient for pulling out the vascular clamp through the traction line in the open operation.

Optionally, the outer side surface of the pressing part of the clip body is provided with an anti-slip line 17. The anti-skidding lines can adopt the form of raised grains, and the hemostatic clamp is convenient for a doctor to pinch in the operation process, so that the hemostatic clamp is prevented from slipping when the doctor holds the hemostatic clamp.

Optionally, the inside surface of the grip portion is uniformly provided with a plurality of engaging teeth 18. The occluding teeth of the two clip bodies can be occluded with each other, so that the blood vessel can be safely occluded, and the function of completely clamping the blood flow is realized.

Optionally, the cross-section of the meshing teeth is trapezoidal. Adopt trapezoidal line, can make the vascular wall in the occlusion tooth smooth bending, very big reduction to vascular damage.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
