Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

Example 1

The precise hemostasis device for bone space disclosed in this embodiment includes a hemostatic gun and a hemostatic bullet. The propulsion port 5, the propulsion port 5 and the first drug outlet 6 in the bottle body 1 are an article compartment, and the article compartment, the propulsion 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.

As shown in Figure 1 and 2, 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, gelatin sponge compartment 3 and fluid gelatin compartment 4 Internal communication, the rear end of the renin cotton sheet compartment 2 communicates with the propulsion port 5, and the front end of the fluid gelatin compartment 4 communicates with the first drug outlet 6. The renin cotton sheet compartment 2 is equipped with a renin cotton sheet 7 , the gelatin sponge compartment 3 is equipped with a gelatin sponge 8 , and the fluid gelatin compartment 4 is reserved for fluid gelatin 9 . When using the hemostatic bullet, as shown in FIG. 3 , inject the fluid gelatin 9 into the fluid gelatin chamber 4 from the first drug outlet 6 . A plug 10 can be provided at the 5 places of the propelling port, which can be removed during use.

As shown in Figure 4, the hemostatic gun includes a push rod 12 and a cylinder 11 for holding hemostatic bombs. The side wall of the cylinder 11 has a loading opening 14, and the front end of the push rod 12 is inserted into the cylinder 11 from the rear end of the cylinder 11. The front end of the push rod 12 is fixedly connected with a push block 13 that can enter the interior of the article compartment through the push port 5 of the bottle body 1, and the front end of the cylinder body 11 has a second drug outlet 15. Wherein, the push block 13 is a piston adapted to the inner diameter of the article bin.

In this embodiment, the second drug outlet 15 faces obliquely forward of the cylinder body 11, and when the push block 13 is pushed forward, it can ensure that the bottle body 1 of the hemostatic bullet will not be pushed out. Further, the front end surface of the barrel 11 is an arc surface 16, and an oblique opening is provided on the arc surface 16 to form the second drug outlet 15. The arc design can easily extend into the bone gap.

As shown in FIG. 5 , when in use, the hemostatic bomb is loaded into the hemostatic gun from the loading opening 14 , and the front end of the bottle body 1 faces the front end of the cylinder body 11 . Extend the front end of the hemostatic gun to the bone space or spinal cavity where bleeding needs to be stopped.

As shown in Figure 6, push the push rod 12 forward, and the bottle body 1 is forced to move forward along the cylinder 11 until it cannot move; as shown in Figure 7, continue to push the push rod 12 forward, and the push block 13 passes through the bottle body. The propulsion port 5 of 1 enters the interior of the product compartment, and presses the renin cotton sheet 7 forward, so that the medicine in the product compartment moves forward under force, and then the fluid gelatin 9 at the front passes through the first drug outlet 6, The second drug outlet 15 is squeezed out, quickly reaching and occupying the irregular bone space, and promoting blood coagulation; then, the gelatin sponge 8 is squeezed out quickly, and the gelatin sponge 8 expands to play a physical blocking effect; finally, renin The cotton pad 7 is quickly extruded, and the renin cotton pad 7 can provide adrenaline in time to shrink local small blood vessels, filter and absorb excess water and blood, keep the local area dry, and promote rapid blood coagulation at the bleeding point. After the hemostasis is successful, remove the kidney Plain cotton sheet7.

One hemostatic bullet, two hemostatic bullets, or even multiple hemostatic bullets can be installed in one hemostatic gun. In this embodiment, one hemostatic bullet is housed in one hemostatic gun.

The invention has the advantages of simple structure and convenient operation. Just by pushing the push rod, the three kinds of medicines can be quickly and accurately injected in sequence to the position to be blocked. The present invention can reduce the liquid gelatin that consumes each time several times, if only liquid gelatin is used, the liquid gelatin of 1ml can only be used about 3-5 times; It is less costly than just using liquid gelatin to stop the bleeding.

Example 2

The difference between this embodiment and Embodiment 1 is that, as shown in Figure 8, 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, it can be ensured that the bottle body 1 of the hemostatic bomb will not be pushed out.

Example 3

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

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.

Example 4

The difference between this embodiment and the previous three embodiments is that, as shown in FIG. 10 , one hemostatic gun in this embodiment is equipped with two hemostatic bullets, and multiple hemostatic bullets can be used accumulatively. The number of hemostatic bullets can be loaded as required.

The invention can stop bleeding precisely, quickly, and simultaneously complete blood sucking and hemostasis; it can be recycled, and the cost is low; the operation difficulty is small, the difficult bone space hemostasis technique is simplified, and it is suitable for various bone space hemostasis.

Certainly, the present invention also can have other multiple implementation modes, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes All changes and modifications should belong to the scope of protection of the appended claims of the present invention.
