Description

Peritoneoscope vein hemostatic forceps

Technical Field

The utility model belongs to the technical field of medical auxiliary instrument, specifically be a peritoneoscope vein hemostatic forceps.

Background

In recent years, the laparoscopic technique has been rapidly developed and widely applied to hepatobiliary pancreas and gastrointestinal surgery (figure one, the laparoscopic operation hole is 1.2 cm), and particularly in laparoscopic pancreaticoduodenectomy and hepatectomy, the laparoscopic surgery is different from the open surgery in that accidental bleeding in portal vein surgery and accidental bleeding in inferior vena cava are often faced, and the accidental bleeding in laparoscopic surgery causes uncertain factors to the surgery and even causes operation failure, and the operation needs to be completed by opening the abdomen, so once the venous bleeding occurs, the first time is easy and orderly treatment is very important. Effective bleeding control is a precondition for ensuring effective hemostasis, in the prior clinical practice process, a related hemostasis device is lacked, bleeding is often controlled by a main knife and a pair of auxiliary forceps jaws through operation, for bleeding with small damage, bleeding control is easily realized through the forceps jaws, once the damage is large, the blood vessel groove is easily torn due to the forceps jaws in the bleeding process, the small break is changed into a large break, catastrophic effect in the operation is caused, bleeding in the operation of a patient is increased, and even the laparoscopic operation is transferred into an open surgery.

Once bleeding of the veins occurs in an open surgery, bleeding control is easy to realize through left-hand compression of a main knife or clamping of the mouse dentate forceps, see the attached drawings 1 and 2, but the mouse dentate forceps have the defects that after a blood vessel of the clamping forceps is cut, suture hemostasis can be only carried out on the outer side of the mouse dentate forceps, the blood vessel stenosis is easy to cause, fine operation is not facilitated, and the laparoscope requires very fine operation, so that the vein hemostasis device for the laparoscope is urgently needed to be produced, the defects can be overcome, and the requirement for simplicity and convenience in operation of the laparoscope is met.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

The first embodiment is as follows:

as shown in fig. 3-4, the present invention discloses a laparoscopic vein hemostatic forceps, comprising a first forceps 1 and a second forceps 2 pivotally connected to each other, wherein the first forceps 1 comprises a first forceps head 11 and a first forceps handle 12 at two ends, the second forceps 2 comprises a second forceps head 21 and a second forceps handle 22 at two ends, a first through hole 13 is provided in the first forceps head 11, a second through hole 23 is provided in the second forceps head 21, the first through hole 13 and the second through hole 23 form a suture through hole 3 for suturing the vein 4 when the first forceps head 11 and the second forceps head 21 abut against each other, so that the bleeding point 41 of the vein 4 is clamped by the first forceps head 11 and the second forceps head 21, the bleeding point 41 and the area near the bleeding point 41 are both in the suture through hole 3, thereby, the external suture of the vein forceps 9 of the prior art is changed into the internal suture of the present invention, the suture 5 can be sutured as close to the bleeding point 41 as possible, the size of the inner diameter H of the venous vessel 4 at the suture 5 is increased as much as possible to avoid affecting blood flow.

In this embodiment, in order to achieve the effect of firmly clamping the vein 4 by the first forceps head 11 and the second forceps head 21 and prevent the first forceps head 11 and the second forceps head 21 from sliding off, the faces of the first forceps head 11 and the second forceps head 21 opposite to each other are provided with saw teeth, and the saw teeth on the first forceps head 11 and the saw teeth on the second forceps head 21 can be engaged with each other.

In the present embodiment, in order to automatically clamp the first jaw 11 and the second jaw 21, a coil spring 6 for driving the first jaw 11 and the second jaw 21 to abut against each other is disposed between the first jaw handle 12 and the second jaw handle 22, and one end of the coil spring 6 is connected to the first jaw handle 12 and the other end is connected to the second jaw handle 22. Meanwhile, the outer sides of the first forceps handle 12 and the second forceps handle 22 are provided with forceps handle force application points 7, concave-convex anti-slip lines are arranged on the forceps handle force application points 7, when the forceps are used, under the elastic action of the spiral spring 6, the first forceps head 11 and the second forceps head 21 are abutted and clamped, at the moment, a surgeon applies pressure on the forceps handle force application points 7, and the first forceps head 11 and the second forceps head 21 can be opened to further isolate the area near the bleeding point 41.

Meanwhile, in this embodiment, in order to facilitate the operation and prevent the interference with the sight, the first binding clip 11 and the second binding clip 21 are in an arc structure bent towards the same side, the first through hole 13 and the second through hole 23 are square holes with the same size, the size of each square hole is 8mm × 8mm, and the thickness of the outer wall of each square hole is 2 mm.

Example two:

as shown in fig. 5, in the present embodiment, the main structure is the same as the first embodiment, except that: a C-shaped spring piece 8 is arranged between the first clamp handle 12 and the second clamp handle 22, one end of the C-shaped spring piece 8 is connected with the first clamp handle 12, and the other end of the C-shaped spring piece 8 is connected with the second clamp handle 22. Specifically, a plurality of threaded holes 14 are formed in the first forceps handle 12 along the length direction of the first forceps handle, one end of the C-shaped spring piece 8 is detachably fixed in the threaded hole 14 through a screw 15, when the end portion of the C-shaped spring piece 8 is connected to the threaded hole 14 close to the pivoting position, the elastic force of the C-shaped spring piece 8 is increased, the clamping force of the first forceps head 11 and the clamping force of the second forceps head 21 are correspondingly increased, when the end portion of the C-shaped spring piece 8 is connected to the threaded hole 14 far away from the pivoting position, the elastic force of the C-shaped spring piece 8 is reduced, and the clamping force of the first forceps head 11 and the clamping force of the second forceps head 21 are correspondingly reduced, so that the clamping force of the first forceps head 11 and the clamping force of the second forceps head 21 are adjustable.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
