Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in 1~8, a hemostatic material pusher for vascular puncture, which is used in conjunction with a vascular sheath that pierces a blood vessel of a human body; the pushing device comprises an outer sleeve 1 sleeved on a sheath tube 9, a pushing mechanism is arranged at the tail end of the outer sleeve 1, a hemostatic material 6 is arranged in the outer sleeve 1, the head end of the outer sleeve 1 is connected with a connector 4, a strip-shaped plastic diaphragm 5 is arranged on the connector 4, and the extension direction of the plastic diaphragm 5 is consistent with that of the sheath tube 9; the pushing mechanism pushes the hemostatic material 6 to move between the plastic membrane 5 and the sheath 9 along the extending direction of the sheath 9.

The sheath 9 is a component of a vascular sheath, and as shown in fig. 2, the sheath 9 is inserted into the body of a patient at 45 degrees, sequentially passes through the skin and subcutaneous tissue 7 of the patient, and the tail end is inserted into a blood vessel 8 of the patient. The length of the sheath 9 is about 12cm, and the surface of the sheath 9 is provided with scale marks. The doctor can judge the depth of the sheath 9 inserted into the body of the patient according to the scale marks. The utility model is suitable for a vascular sheath of 4F-8F specification, to too big vascular sheath among the actual operation, be more suitable for and use the stitching instrument to stanch.

As shown in fig. 3, the outer sleeve 1 is formed by combining a first sleeve 101 and a second sleeve 102, track grooves 106 are formed on the first sleeve 101 and the second sleeve 102, and the track grooves 106 of the first sleeve 101 and the second sleeve 102 are fastened together to form an inner conduit for the sheath 9 to pass through. The outer sleeve 1 is made of plastic and is used for forming a pipeline and guiding the pushing of the hemostatic material 6. Because the vascular sheath has inserted in advance in the patient body, and the vascular sheath other end is thicker, and outer tube 1 can't directly sheathe in, can only design the mosaic structure of this application. Furthermore, in order to enable the first sleeve 101 and the second sleeve 102 to be tightly buckled, a positioning hole 104 and a positioning column 105 are respectively arranged on the opposite surfaces of the first sleeve 101 and the second sleeve 102, and the positioning hole 104 and the positioning column 105 can be tightly plugged after being plugged. Fig. 7 shows a design of the positioning hole 104 and the positioning post 105, wherein a section of the positioning hole 104 is enlarged, and correspondingly, a section of the positioning post having an enlarged outer diameter is matched with the section of the positioning post, and the plastic can be slightly deformed, so that the design does not significantly affect the buckling of the first casing 101 and the second casing 102, and the first casing and the second casing are difficult to be pulled out after being tightly inserted.

Two clamping convex edges 103 are formed on the outer wall of the head end of the outer sleeve 1; the main body of the joint 4 is of a U-shaped structure, and the inner wall of the main body forms a clamping groove matched with the clamping convex rib 103 in shape and position. The joint 4 and the outer sleeve 1 are mutually independent components, and the joint 4 is arranged at the head end of the outer sleeve 1, so that on one hand, the first sleeve 101 and the second sleeve 102 forming the outer sleeve 1 are clamped, and the first sleeve 101 and the second sleeve 102 are prevented from being separated in the using process; on the other hand, a mounting point of the plastic membrane 5 is provided, and one end of the plastic membrane 5 is fixed at the bottom of the U-shaped opening of the joint 4.

The material can be completely absorbed by human body within 4-8 weeks after being implanted into human body.

The pushing mechanism comprises a thumb wheel 2, the thumb wheel 2 is arranged on a thumb wheel support 10, the lower end of the thumb wheel support 10 is fixed on the outer sleeve 1, and the bottom of the thumb wheel 2 is embedded in the outer sleeve 1; the surface of the thumb wheel 2 forms teeth which are engaged with the rack 3 inserted into the outer sleeve 1. The front end of the rack 3 pushes the hemostatic material to move along the extending direction of the sheath 9.

The utility model discloses a use method does:

s1: after the surface of the sheath 9 is sterilized, the hemostatic material 6 is placed on the surface of the sheath 9, and the first sleeve 101 and the second sleeve 102 are buckled outside the hemostatic material 6 and the sheath 9.

S2: the rack 3 is inserted into the outer sleeve 1 from the tail part, the teeth on the rack 3 are meshed with the teeth on the shifting wheel 2, the shifting wheel 2 is shifted, the rack 3 gradually enters the outer sleeve 1, and the hemostatic material 6 can be pushed to move along the outer sleeve 1.

S3: the length of the required plastic diaphragm 5 is calculated according to the actual depth of the sheath 9 inserted into the patient, and the excess length in the plastic diaphragm 5 is cut off by medical scissors.

S4: the plastic diaphragm 5 is gradually inserted into the body of the patient along the direction of the sheath 9, and the plastic diaphragm 5 and the sheath 9 are mutually attached in a large area in the body of the patient.

S5: the joint 4 is sleeved at the front end of the outer sleeve 1, the dial wheel 2 is continuously stirred, and the rack 3 further pushes the hemostatic material 6 to advance and push the hemostatic material to a position close to a punctured blood vessel in a patient body.

S5: the sheath 9 and the plastic septum 5 are gently pulled out and gently pressed, so that the hemostatic material 6 adheres to the surface of the blood vessel.
