Problems solved by technology

Due to the large size and weight of the hemostatic forceps, it is impossible to carry enough hemostatic forceps at all times, so gauze and bandages can only be used to stop bleeding. If the pressure time is too long, a large area of ​​tissue ischemia and necrosis will be caused. play a rapid hemostasis

Embodiment Construction

[0012] like figure 1 As shown in the schematic diagram of the structure of the sliding hemostatic needle of the present invention, two push rod hemostatic needles [11] are installed on one end of the push rod [5], and one casing hemostatic needle [10] is installed on one end of the housing [9]. When the push rod [5] is slid, the push rod hemostatic needle [11] and the casing hemostatic needle [10] fit together, thereby achieving the purpose of clamping the bleeding site.

[0013] The automatic locking device [7] attracts the cards exposed outside the housing [9] through the magnetic material [1] on the housing [9], and the cards inside the housing [9] fall under the action of the rotating shaft [2]. On the locking tooth [3] of the push rod [5], so as to prevent the push rod [5] from bouncing backwards, it can conveniently and quickly lock the position of the hemostatic needle. When the unlock button [6] is pressed, the casing [9] The internal card is lifted away from the lock...

Abstract

The invention discloses a sliding hemostatic needle which comprises an automatic locking device, an automatic flick device, an unlocking button, hemostatic needle bodies, a push rod and a shell, wherein all the components are arranged in the shell. A clamping sheet is arranged on the shell. The clamping sheet can freely fall onto clamping teeth of the push rod under the action of a small-sized magnet to fix the hemostatic needle bodies, the clamp sheet falling onto the clamp teeth is lifted when the unlocking button is pressed so that a locking state can be removed, and the hemostatic needle bodies return to an original position through the automatic flick device arranged at one end of the shell. The sliding hemostatic needle has the advantages of being simple in structure, convenient to carry and flexible in use; the hemostatic effect is achieved in a manner that a bleeding part is clamped by the hemostatic needle bodies, and the sliding hemostatic needle has the obvious hemostatic effect on patients suffering from vascular injury hemorrhage and patients suffering from coagulation disorders.

Description

technical field [0001] The invention relates to a hemostatic device, in particular to a sliding hemostatic needle. Background technique [0002] At present, there are mainly two methods of hemostasis: pressure hemostasis and drug hemostasis. When there is massive bleeding due to vascular injury or coagulation dysfunction, neither of these two methods can play a good hemostasis effect. To stop the bleeding. Due to the large size and weight of the hemostatic forceps, it is impossible to carry enough hemostatic forceps at all times, so gauze and bandages can only be used to stop bleeding. If the pressure time is too long, a large area of ​​tissue ischemia and necrosis will be caused. Play a rapid hemostasis. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a small and convenient sliding hemostatic needle that can quickly clamp the bleeding site to prevent bleeding. [0004] To achieve the ...
