## Abstract

Disclosed is a hemostatic agent applicator capable of effectively placing a fluid hemostatic agent on an incision surface. The present invention is a hemostatic agent applicator for use in disposing a fluid hemostatic agent, including a tool body in which a hollow part surrounded by a wall part is formed and which includes an open end part on a downstream side of the wall part, and an inlet provided to a portion of the wall part of the tool body to communicate with the hollow part. This hemostatic agent applicator is useful in medical settings relating to surgical procedures, particularly for surface bleeding of a liver and internal organ surgery such as a spleen and fibroid enucleation. An applicator further reduced in size can be applied not only in abdominal surgery, but in endoscopic surgery as well.

## Claims

### Claim 1

A hemostatic agent applicator for use in disposing a fluid hemostatic agent, comprising:
a tool body in which a hollow part surrounded by a wall part is formed and which includes an open end part on a downstream side of the wall part, and which includes a top plate on an upstream side of the wall part;
an inlet provided to be inclined at a predetermined angle on the top plate of the tool body to communicate with the hollow part, and
a flexible movable member provided in the wall part, wherein:
the open end part is capable of coming into direct contact with an incision surface formed during surgery such that the tool body covers the incision surface when the open end part comes into direct contact with the incision surface, and
a diameter of the open end part is longer than a height of the wall part.

### Claim 2 (depends on 1)

The hemostatic agent applicator according to claim 1, wherein a distal end of the open end part is provided with a skirt along a circumference direction of the tool body.

### Claim 3 (depends on 1)

The hemostatic agent applicator according to claim 1, wherein the inlet is provided with a T shape stopcock.
