Detailed Description

The technical solutions of the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

As shown in fig. 1 to 4, the embodiment provides a hemostatic suture forceps for minimally invasive surgery, which comprises a forceps body and a forceps handle 4;

the pliers body comprises a first pliers body 1 and a second pliers body 2 which are movably connected through a first rotating shaft 3 and can be buckled or opened along the first rotating shaft 3;

the clamp handle 4 is integrally formed and arranged on the first clamp body 1 and the second clamp body 2.

The two groups of pliers heads 5 can be driven by the first pliers body 1 and the second pliers body 2 to open and close, and the two groups of pliers heads 5 are smooth and mutually attached to form surface contact on the wall surfaces close to each other;

the middle part of the clamp head 5 is bent upwards to form an arc body, and when in hemostasis clamping, viewing angle observation is facilitated.

The end integrated into one piece of binding clip 5 is provided with returns the cutting edge portion 6, return cutting edge portion 6 at first opposite direction along the binding clip 5 bending direction is followed again the binding clip 5 bending direction extends the back turn back, binding clip 5 is in return cutting edge portion 6 initial bending portion still integrated into one piece is provided with closing part 7, closing part 7 to return cutting edge portion 6 tip extension and do not contact with return cutting edge portion 6, return cutting edge portion 6 with closing part 7 forms "C" shape structure in the end of binding clip 5, when pressing from both sides the bleeding point with the bleeding position, the C shape structure can follow the rear half surrounding type of bleeding point or bleeding portion and carry out the clamp down, and bleeding point or bleeding portion are in this moment return cutting edge portion 6 tip with the position between the tip of closing part 7 makes bleeding point or bleeding portion's blood supply break off, makes bleeding point and bleeding portion expose simultaneously, makes things convenient for doctor to sew up the operation.

The middle part of the forceps head 5 is also provided with clamping holes 8, and two groups of clamping holes 8 form empty slots when the two groups of forceps heads 5 are closed, so that the forceps can serve as tissue forceps temporarily.

The two groups of pliers handles 4 are respectively and fixedly provided with an upper ratchet plate 9 and a lower ratchet plate 10 at the ends close to each other, and ratchets connected with each other in a meshed mode are arranged at the end faces close to each other of the upper ratchet plate 9 and the lower ratchet plate 10, so that a doctor can loosen hands to perform other operations after the pliers are clamped, and the two groups of pliers heads 5 cannot be opened.

In this embodiment, the doctor controls the opening and closing of the two groups of forceps heads 5 by holding the forceps handles 4, and uses the arc body formed by bending the middle parts of the forceps heads 5 upwards, so that when in hemostasis and clamping, the back spike part 6 and the closing part 7 are clamped from the rear of the bleeding point or the bleeding part, and the back semi-enclosed type of the bleeding point or the bleeding part can be clamped by using the C-shaped jaws formed by the back spike part 6 and the closing part 7, and at the moment, the bleeding point or the bleeding part is positioned between the end part of the back spike part 6 and the end part of the closing part 7, so that the blood supply of the bleeding point or the bleeding part is interrupted, and meanwhile, the bleeding point and the bleeding part are exposed, so that the doctor can conveniently suture.

Example 2

As shown in fig. 5 to 6, based on the same concept as the first forceps body 1 of the above embodiment, the present embodiment also proposes a hemostatic suture forceps for minimally invasive surgery, which is different in that a forceps body is provided with a turning part between the forceps body and the forceps head 5, the turning part includes an inner side plate 12 fixedly mounted on the forceps head 5 and an outer side plate 11 fixedly mounted on the forceps body, and the outer side plate 11 and the inner side plate 12 are rotatably connected through a second rotating shaft 13, so that the forceps head 5 can turn around the forceps body, and when the forceps head 5 and the forceps body form a folding angle, a doctor further conveniently bypasses normal tissues to perform hemostatic forceps operation on a bleeding part.

The inner side plate 12 is close to the polygonal one end of the pincers body, the inside of the pincers body has offered the spout 14, sliding installation has the kicking block 15 in the spout 14, the kicking block 15 with fixed mounting has ejection spring 16 between the spout 14, utilizes ejection spring 16's elasticity messenger's kicking block 15 to contact with the polygonal plane of inner side plate 12 all the time and support tightly to make binding clip 5 unable easy change self rotation direction, be convenient for keep binding clip 5's stability before the centre gripping.

In this embodiment, firstly, by pulling the binding clip 5, the angle between the binding clip 5 and the clip body is controlled, and in the pulling process, the ejector block 15 is always clung to the polygonal plane of the inner side plate 12 under the action of the elastic force of the ejector spring 16, so that the binding clip 5 can keep a certain fixed bending angle unchanged, and when the tissue deeper in the body is clamped, the binding clip 5 forms a bending angle with the clip body, thereby further facilitating the doctor to bypass normal tissue to perform hemostatic clamping operation on the bleeding part.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
