Abstract

In an adhesive sprayer for a living body, a hard insert portion extends from a sprayer body, a bendable portion extends from a distal end of the insert portion, and a nozzle portion is disposed on a distal end of this bendable portion. Gas from a gas inlet port formed in the sprayer body is injected from a gas injection port formed in the nozzle portion after passing through a passage which is allowed to extend through the interiors of the sprayer body, insert portion and bendable portion. Adhesive from an adhesive inlet port formed in the sprayer body is injected from an adhesive discharge port formed in the nozzle portion after passing through another passage which is allowed to extend through the interiors of the sprayer body, insert portion, and bending portion. The bending portion is bent by controlling a control member mounted on the sprayer body via a control cable extending through the interiors of the sprayer body, insert portion and bendable portion.

Claims

1. An adhesive sprayer for a living body, said adhesive sprayer comprising:

(d) a nozzle portion disposed on a distal end of said bendable portion, said nozzle portion including an adhesive discharge port and a gas injection port;

(e) first passage means for intercommunicating said adhesive inlet port of said sprayer body and said adhesive discharge port of said nozzle portion so that an adhesive is

(d) a nozzle portion disposed on a distal end of the bendable portion, the nozzle portion including an adhesive discharge port and a gas injection port;

(e) first passage means for intercommunicating the adhesive inlet port of the sprayer body and the adhesive discharge port of the nozzle portion so that an adhesive is allowed to pass therethrough, the first passage means being disposed within the sprayer body, hard insert portion and bendable portion, the first passage means being bendable at least at the bendable portion;

(f) second passage means for intercommunicating the gas inlet port of said sprayer body and the gas injection port of the nozzle portion so that a pressurized gas is allowed to pass therethrough, the second passage means being disposed within the sprayer body, hard insert portion and bendable portion, said second passage means being bendable at least at the bendable portion;

(g) control means for remote controlling the bendable portion, the control means including a control member disposed on the sprayer body and at least one control cable, one end of the cable being secured to the control member and the other end thereof being secured to a distal end of the bendable portion;

wherein the first passage means has a first tube, the first tube being connected at a rear end thereof to the adhesive inlet port and inserted at a distal end portion thereof into the gas injection port formed in the nozzle portion, a gap for allowing allowed to pass therethrough, said first passage means being disposed within said sprayer body, insert portion and bendable portion, said first passage means being bendable at least at said bendable portion;

(f) second passage means for intercommunicating said gas inlet port of said sprayer body and said gas injection port of said nozzle portion so that a pressurized gas is allowed to pass therethrough, said second passage means including a separate flexible tube and being disposed within said sprayer body, insert portion and bendable portion, said second passage means being bendable at least at said bendable portion; and

(g) control means for remote controlling said bendable portion, said control means including a control member disposed on said sprayer body and at least one control cable, one end of said cable being secured to said control member and the other end thereof being secured to a distal end of said bendable portion.

2. An adhesive sprayer according to claim 1, in which said control member includes a shaft extending through a wall of said sprayer body, a control knob mounted on an external end of said shaft and a pulley mounted on an internal end of said shaft, said control cable being secured to a peripheral surface of said pulley.

3. An adhesive sprayer according to claim 1, in which said first passage means has a first tube, said first tube being connected at a rear end thereof to said adhesive inlet port and inserted at a distal end portion thereof into said gas injection port formed in said nozzle portion, a gap for allowing supply of the pressurized gas being formed between an inner peripheral surface of said gas injection port and an outer peripheral surface of the distal end portion of said first tube, an opening of the distal end portion of said first tube being provided as said adhesive discharge port.

4. An adhesive sprayer according to claim 3, in which said gas injection port has three or more projections circumferentially spacedly formed in the inner peripheral surface of said gas injection port, the distal end portion of said first tube being press fitted among said projections in an elastically deformed fashion.

5. An adhesive sprayer according to claim 3, in which two of said adhesive inlet ports are formed in said sprayer body and two of said adhesive discharge ports are formed in said nozzle portion, said first passage means including two of said first tubes.

6. An adhesive sprayer for a living body, said adhesive sprayer comprising:

(a) a sprayer body having an adhesive inlet port and a gas inlet port;

(b) a hard insert portion extending from the sprayer body;

(c) a bendable portion extending from a distal end of the hard insert portion;

supply of the pressurized gas being formed between an inner peripheral surface of the gas injection port and an outer peripheral surface of the distal end portion of the first tube, an opening of the distal end portion of the first tube being provided as the adhesive discharge port; and

wherein said second passage means has a flexible second tube, a rear end of said second tube being continuous with said gas inlet port, a distal end of said second tube being connected to said nozzle portion and continuous with said gas injection port, said first tube being inserted into and extending through the interior of said second tube.

7. An adhesive sprayer for a living body, said adhesive sprayer comprising:

(a) a sprayer body having an adhesive inlet port and a gas inlet port;

(b) a hard insert portion extending from the sprayer body;

(c) a bendable portion extending from a distal end of the hard insert portion;

(d) a nozzle portion disposed on a distal end of the bendable portion, the nozzle portion including an adhesive discharge port and a gas injection port;

(e) first passage means for intercommunicating the adhesive inlet port of the sprayer body and the adhesive discharge port of the nozzle portion so that an adhesive is allowed to pass therethrough, the first passage means being disposed within the sprayer body, hard insert portion and bendable portion, the first passage means being bendable at least at the bendable portion;

(f) second passage means for intercommunicating the gas inlet port of said sprayer body and the gas injection port of the nozzle portion so that a pressurized gas is allowed to pass therethrough, the second passage means being disposed within the sprayer body, hard insert portion and bendable portion, said second passage means being bendable at least at the bendable portion;

(g) control means for remote controlling the bendable portion, the control means including a control member disposed on the sprayer body and at least one control cable, one end of the cable being secured to the control member and the other end thereof being secured to a distal end of the bendable portion;

wherein the first passage means has a first tube, the first tube being connected at a rear end thereof to the adhesive inlet port and inserted at a distal end portion thereof into the gas injection port formed in the nozzle portion, a gap for allowing supply of the pressurized gas being formed between an inner peripheral surface of the gas injection port and an outer peripheral surface of the distal end portion of the first tube, an opening of the distal end portion of the first tube being provided as the adhesive discharge port; and
