Description

Suture hemostatic forceps Technical Field The utility model relates to the technical field of medical appliances, in particular to a suture hemostatic forceps. Background Blood vessel damage bleeding is a common phenomenon in surgery, where blood vessel sidewall damage is more common. The common hemostasis method mainly comprises two methods, namely, blocking the blood vessel by using a vascular clamp such as a titanium clamp or a Hom-Lock clamp, and the like, and suturing and ligating the bleeding point by using a suture needle, and particularly, the bleeding point which is difficult to separate and expose the blood vessel is more suitable for suturing and hemostasis. However, in thoracoscopic surgery, particularly in single-hole thoracoscopic surgery, accurate suturing is actually difficult due to mutual interference between surgical instruments, and particularly in the case of an area where the operation space is small or surgery by young doctors, the suturing difficulty is further increased. In addition, when the bleeding amount is large, the bleeding point is first clamped by a vascular clamp to control bleeding, and then the suture needle is clamped by a needle holder to suture. However, the blood vessel forceps are clamped at the bleeding part, so that the suturing operation of the needle holder is blocked, the suturing becomes very difficult, and if the blood vessel forceps are loosened, blood can immediately overflow the bleeding point, so that a doctor cannot see the exact suturing point, and the suturing cannot be accurately performed. Disclosure of utility model The utility model aims to provide the suture hemostatic forceps which are simple and convenient in use mode and can safely and efficiently suture the bleeding points on the side wall of the blood vessel. In order to achieve the aim, the utility model provides a suture hemostatic forceps which comprises a forceps handle, a forceps body and a forceps mouth, wherein the forceps mouth is provided with two forceps leaves which can be closed, channels are arranged in the two forceps leaves, the channels penetrate forwards from the near rear end of the outer side surface of the forceps leaf to the tip end of the forceps leaf, when the forceps mouth is closed, the channel openings at the tip ends of the two forceps leaves correspond to each other, the channels in the two forceps leaves are communicated with each other, and a U-shaped path is formed in the forceps mouth by the two channels. Furthermore, the suture needle with flexibility is matched, the tail end tip of the suture needle is combined with the suture thread, the suture needle penetrates from the channel of one forceps blade and passes through the channel opening at the tip ends of the two forceps blades to the channel of the opposite forceps blade, and the suture needle realizes large-angle bending when passing through the channel opening at the tip ends of the two forceps blades. Further, the channel forms an arc-shaped guide section at the tip end of the pliers blade, and the arc-shaped guide sections of the two pliers blades are butted to form a turning section at the end of the U-shaped path. Further, a pusher for pushing the suture needle in the passage is also provided, the pusher comprises an outer sleeve and a piston displaceable in the outer sleeve, the tail end tip of the suture needle is inserted into the front end of the outer sleeve and props against the front end of the piston, and the suture needle is pushed out of the outer sleeve when the piston is pushed forward. Further, the diameter of the tail end tip of the suture needle is 0.15mm, the length of the suture needle is 27mm, the suture is 4-0 absorbable or non-absorbable thread, the outer diameter of the outer sleeve is not more than 0.45mm, the inner diameter is 0.35mm, and the diameter of the piston is not more than 0.35mm. Further, the length of the inner part of the outer sleeve, where the piston is arranged, is smaller than that of the outer sleeve, the tail part of the outer sleeve is provided with a blocking wall, the tail part of the piston is provided with a stop block, and the stop block is blocked outside the blocking wall. Further, the two pincers leaves are gradually reduced in width forward and the front ends of the pincers leaves are lifted upwards. Further, the channel inner diameter was 0.45mm. Further, the inner sides of the two clamp leaves are in a zigzag shape. Furthermore, the suture hemostatic forceps are double-joint forceps, and a sliding plate type structure is adopted between the forceps handles and the forceps bodies. After the scheme is adopted, when the suture hemostatic forceps are used, the forceps mouth is clamped at a bleeding point, after bleeding is stopped, the forceps mouth is opened, the suture needle with the suture thread is pushed into the passage through the passage opening at the position close to the rear end of the side surface of one forceps leaf, and the passage open
