Nail magazine assembly storing hemostatic agent

Abstract

The invention provides a nail magazine assembly storing a hemostatic agent, which includes an anvil, a nail magazine and a cutting knife. The anvil includes a nail abutment seat and a cover connected to the nail abutment seat. One side of the warehouse, and the accommodating space is surrounded by the nail anvil, a liquid storage chamber for storing the hemostatic agent is arranged in the accommodation space, and the hemostatic agent is stored in the liquid storage chamber, and the nail magazine assembly also includes a The executive member for opening the warehouse, the cutting knife is provided with a guide channel for guiding the flow of the hemostatic agent along the cutting direction, and when the cutting knife advances in the cutting direction to cut, the executive member will open the liquid storage chamber, so that the hemostatic agent flows out of the storage chamber. The liquid tank, the guiding channel guides the hemostatic agent to flow to the position cut by the cutting knife. In the present invention, a liquid storage chamber is set on the nail anvil to store the hemostatic agent, and the opening of the liquid storage chamber and the guidance of the hemostatic agent are realized through the movement of the cutting knife, so that the hemostatic agent can flow along the designated flow channel to the track after cutting, and assist the tissue to stop bleeding .

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a nail box assembly stored with a hemostatic agent. Background technique [0002] Linear cutting staplers are widely used in surgical operations for tissue cutting and tissue suturing after cutting. The staple magazine assembly of a linear cutting stapler generally includes a staple cartridge, an anvil, staples, a staple pusher, and a cutting knife. The cut tissue is sutured. [0003] In order to reduce tissue bleeding, it is a trend for staplers to attach hemostatic material to the nail box at present. The hemostatic material can be used to stop the bleeding of the cut tissue incision and suture position; in the prior art, there is no storage of hemostatic material in the nail box. Records, or the storage method of hemostasis on the nail box is relatively complicated and inconvenient to operate. At the same time, when the hemostat is stored in the nail mag...

Problems solved by technology

[0003] In order to reduce tissue bleeding, it is a trend for staplers to attach hemostatic material to the nail box at present. The hemostatic material can be used to stop the bleeding of the cut tissue incision and suture position; in the prior art, there is no storage of hemostatic material in the nail box. Records, or the storage method of the hemostat on the nail box is relatively complicated and inconvenient to operate

At the same time, when the hemostat is stored in the nail magazine, when the cutting knife moves forward to cut, the hemostat will be squeezed to both sides, and there is a problem that the hemostatic supply at the tissue incision is not in place or uneven. Affect the hemostatic effect
