Embodiment 1

[0037] The bone gap precise hemostasis device disclosed in this embodiment includes a hemostatic gun and a hemostatic bomb, such as figure 1 As shown, the hemostatic bullet includes a bottle body 1, the front end of the bottle body 1 has a first drug outlet 6, and the rear end of the bottle body 1 is provided with a propulsion port 5, and there is a gap between the propulsion port 5 and the first drug outlet 6 in the bottle body 1. The article warehouse, the article warehouse, the propelling port 5, and the first drug outlet 6 are internally connected. Wherein, the hemostatic material is housed in the item compartment. The hemostat at least includes one of renin cotton sheet 7 , gelatin sponge 8 and fluid gelatin 9 . The bottle body 1 is made of plastic.

[0038] Such as figure 1 , 2 As shown, the article compartment is divided into renin cotton compartment 2, gelatin sponge compartment 3 and fluid gelatin compartment 4 from back to front. Renin cotton compartment 2, gelat...

Embodiment 2

[0046] The difference between this embodiment and embodiment 1 is: as Figure 8 As shown, in this embodiment, the second drug outlet 15 faces directly in front of the cylinder body 11, and the inner diameter of the second drug outlet 15 is smaller than the outer diameter of the bottle body 1. When the push block 13 is pushed forward, the bottle of the hemostatic bullet can be guaranteed. Body 1 will not be pushed out.

Embodiment 3

[0048] The difference between this embodiment and embodiment 1 or 2 is: as Figure 9 As shown, the hemostatic gun in this embodiment also includes a suction catheter 17, the suction catheter 17 is located outside the cylinder 11 and connected to the cylinder 11, the suction head 18 of the suction catheter 17 extends to the front end of the cylinder 11, and the rear end of the suction catheter 17 Extends to the rear end of cylinder 11. Preferably, the suction port of the suction head 18 faces the opposite side of the barrel 11 .

[0049] In this embodiment, a suction catheter 17 is added. When in use, the rear end of the suction catheter 17 is connected to a suction device, and the suction head 18 at the front end can suck excess blood and other fluids around the bleeding gap.

Abstract

The invention relates to an accurate hemostatic device for bone gaps. The accurate hemostatic device for the bone gaps is characterized in that the accurate hemostatic device comprises a hemostatic gun and a hemostatic bullet which comprises a bottle body; a first drug outlet is arranged on the front end of the bottle body, while a propelling mouth is arranged on the rear end of the bottle body; the portion between the propelling mouth and the first drug outlet in the bottle body is a goods warehouse; the goods warehouse, the propelling mouth and the first drug outlet are internally communicated; the hemostatic gun comprises a push rod and a barrel which is used for holding the hemostatic bullet; a loading opening is arranged on the side wall of the barrel; the front end of the push rod isinserted in the barrel through the rear end of the barrel; the front end of the push rod is fixedly connected with a push block which is capable of entering the inner portion of the goods warehouse through the propelling mouth of the bottle body; a second drug outlet is arranged on the front end of the barrel; at least one of renin cotton sheet, gelatin sponge and fluid gelatin is included as a hemostatic item. The accurate hemostatic device for the bone gap has the advantages of being simple in structure, capable of accurately sending the hemostatic item to the position needing blocking, especially suitable for bone gap hemostasis, easy for the loading and replacing of the hemostatic bullet with the loading opening arranged on the side of the hemostatic gun, and capable of enabling multiple hemostatic bullets to be used cumulatively. Furthermore, the hemostatic device is convenient in operation, small in operation difficulty, and capable of simplifying the difficult technique of hemostasis in bone gaps.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a precise hemostasis device for bone gaps. Background technique [0002] The shape of the bony space is irregular, and it is difficult for the hemostat to accurately reach the bleeding site. At present, the hemostasis in the bone space is slow and difficult. Contents of the invention [0003] The present invention aims to provide a precise hemostasis device in the bone space, which can quickly and accurately stop the hemorrhage, and is less difficult to operate. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is as follows: [0005] The precise hemostasis device for the bone space includes a hemostatic gun and a hemostatic bullet. The hemostatic bullet includes a bottle body. There is an article warehouse between the medicine ports, and the article warehouse, the propulsion port, and the first medicine outlet ar...
