Medical hemostatic device

Abstract

The invention relates to the technical field of medical instruments, in particular to a medical hemostatic device; the medical hemostatic device comprises a gun barrel, a piece discharging mechanism,a piece pushing mechanism and a heating mechanism, wherein a hemostatic piece storage bin used for storing hemostatic pieces is arranged in the gun barrel; a piece discharging channel is formed in thehead of the gun barrel; the piece discharging channel is provided with a piece inlet and a piece outlet, and the piece discharging channel is configured to be a channel for allowing one side of eachhemostatic piece to slide out of the piece outlet firstly and then enabling the other side of the hemostatic piece to slide out; the piece discharging mechanism is used for sequentially conveying thehemostatic pieces in the hemostatic piece storage bin into the piece discharging channel from the piece inlet; the piece pushing mechanism is used for pushing the hemostatic pieces in the piece discharging channel out of the piece outlet; a door body is arranged at the piece outlet; a burr surface is arranged on the door body, and the door body is configured to open the piece outlet during piece discharging, and the burr surface is in contact with the back surface of the hemostatic piece. According to the scheme provided by the invention, the burr surface on the door body can be in contact with the ejected hemostatic piece, so that the ejection resistance of the hemostatic piece is increased, the ejection speed of the hemostatic piece is reduced, and the impact between the hemostatic pieceand a wound of a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical device for hemostasis. Background technique [0002] During surgical operations, local bleeding often occurs. At present, a medical device for hemostasis is generally used to inject a hemostatic sheet to the bleeding site for compression to stop bleeding. [0003] Such as figure 1 As shown, the existing medical device for hemostasis includes a gun barrel 2 as a hemostatic sheet 1 push-out channel and a sheet pushing device, and the sheet pushing device includes a heater that is arranged in the mouth section of the gun barrel 2 in a manner that can move back and forth 3 and a control mechanism for controlling the movement of the heater 3. The gun barrel 2 is also provided with a storage bin 4 for storing the hemostatic patch 1 . When in use, the hemostatic patch 1 is sent into the gun barrel 2 from the storage chamber 4. When hemostasis is required, the doctor...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned medical device for hemostasis has at least the following defects in use: when the hemostatic sheet 1 is pushed out from the mouth of the gun barrel 2 by the heater 3, the speed is too fast, and the collision between the hemostatic sheet 1 and the bleeding part of the patient is likely to cause secondary injury , and the impact will cause greater pain to the patient, so it is urgent to improve this situation
