The inner tube 210 is connected to the outlet port 124 of the head member 100a in a state of being inserted into the outer tube 220. The inner tube 210 has a partition 219 for partitioning into two zones. That is, the inner tube 210 is partitioned into the first chemical liquid passage 215 and the second chemical liquid passage 216 by the partition wall 219, and the first and second discharge ports through which the chemical liquid is discharged at the end of the inner tube 210. (214-1,214-2). The inner tube 210 may be partitioned into the first and second chemical liquid passages 215 and 216 by the partition wall as in the second embodiment, but as shown in FIG. 10, the inner tube 210a may be divided into the first tube without the partition wall. Two chemical liquid passages (215, 216) may be provided, or the inner tube (210b) may be composed of two independent tubes, respectively, to provide the first and second chemical liquid passages (215,216).

The inner tube 210 is directly connected to the outlet port 124 of the head member 100a through the connection port 140. Looking at the movement path of the first and second chemical liquids filled in the first and second syringes 10-1 and 10-2, the first and second inlet ports 120-1 and 120-2 and the first and second euros 122- 1,122-2)-> the first and second holes 125 and 126-> the first and second chemical liquid passages (215 and 216) of the inner tube 210 to the surgical site through the first and second discharge ports (214-1 and 214-2). Discharged.

The outer tube 220 is connected to the connection port 140 formed under the second body 110-2 of the head member 100a. The outer tube 220 has a role of protecting the inner tube 210 and a supply tube guiding the carrier gas to the chemical liquid discharge position. The outer tube 220 has a passage having an inner diameter larger than the outer diameter of the inner tube 210. The carrier gas provided from the gas inflow port 130 flows through the passage 221 of the outer tube 220 and is discharged together with the chemical liquid at the discharging end 224 of the outer tube. The carrier gas may be nitrogen gas, which is one of clean air or inert gas. Looking at the moving path of the carrier gas, the gas provided from the gas supply line is discharged together with the chemical liquid through the gas inlet port-> the inner space of the second body-> the connection port-> the passage of the outer tube-> the discharge port 224 .

On the other hand, the outer tube 220 has a stopper 230. The stopper 230 protrudes from the outer tube 220 close to the head member 100. The stopper 230 is for limiting the insertion depth of the strong member 200 through the laparoscopic bushing 30.

A use state of the chemical liquid injector shown in FIG. 5 will be described with reference to FIG. 9.

The first and second injectors are connected to the first and second inlet ports 120 of the chemical injector 1, and the gas supply line 20 is connected to the gas inlet ports 130. The first and second syringes are mounted on the syringe mounting jig, and fix the head member and the syringe mounting jig by using the fixing clip. Then, after the strong member 200 is inserted into the abdomen through the laparoscopic trocar 30 installed in the abdomen, the end of the strong member is positioned to be close to the surgical site. When the preparation is completed, the operator pushes the pistons of the first and second syringes 10 simultaneously with one hand to supply the first and second chemicals, and the gas supply switch (not shown) of the gas supply line 20 is operated by foot. When the gas is supplied, the first and second chemicals are ejected together with the gas at the end of the strong member 200a, as shown in FIG.

As described above, the chemical injector 1a according to the present embodiment is supplied through independent paths so that mutual mixing (reaction) does not occur until the first chemical and the second chemical are discharged to the surgical site. The chemical is discharged from the end of the strong member 200a and mixed with each other by the supply pressure of the gas, so that the chemical is sprinkled onto the surgical site. The above-mentioned chemical liquid injector 1a is very useful when the first and second chemical liquids having an adhesive component that react with each other and cause aggregation within a few seconds are applied to the laparoscopic surgical site. For example, the first and second chemicals include fibrinogen and thrombin, which are components of a tissue adhesive for stopping bleeding at the surgical site and sealing the wound.

In the second embodiment of the present invention has been described as having a gas inlet port for receiving a carrier gas (nitrogen gas or air) from the gas supply line, the gas inlet port may be omitted if necessary.

12 is a view showing a chemical injector in which a gas inlet port is omitted.

As shown in FIG. 12, the chemical liquid injector 1c is used when a small amount of chemical liquid is to be injected into the localized area. The chemical injector 1c without a gas inlet port is useful when a small amount of chemical is applied to the topical area because the chemical is not sprayed in a spray form. In particular, the chemical injector 1c has an inner tube 210 extending from the outer tube 220 by a predetermined length. The inner tube 210 is extended to protrude from the outer tube 220, the reason for accurately positioning the end of the inner tube 210, which is discharged the chemical liquid to the chemical liquid application site, the inner tube 210 is discharge end The tongs inserted into the abdominal cavity are positioned at the site of application of the chemical and then the chemical is injected.
