Abstract

A medical stapler is provided with a sterilized cartridge removably attached to a stapler body 1 and accommodating a predetermined number of staples 9, a driving mechanism for driving a staple 9 supplied to a driving section at the tip of the cartridge, a manipulating lever 2 for actuating the driving mechanism and a counter device 20. The counter device 20 counts the number of staples 9 driven from the driving mechanism and indicates the counted result.

Claims

1. :

A medical stapler comprising;

a driving mechanism for driving a leading staple of a predetermined number of staples accommodated in a stapler body;

a manipulating lever for actuating the driving mechanism; and

a counter device for counting and indicating a number of staples driven from the driving mechanism.

2. :

The medical stapler according to claim 7, wherein the cartridge is previously sterilized.

3. :

The medical stapler according to claim 1, wherein the counter device counts up the number of staples driven from the driving mechanism.

4. :

The medical stapler according to claim 1, wherein the counter subtracts the number of staples driven from the driving mechanism thereby to indicate the remaining number of staples counted down in the cartridge.

5. :

The medical stapler according to claim 1, wherein the counter device comprises an indicator disc that rotates in synchronism with an operation of the manipulating lever, and

a numeral is successively indicated on a peripheral surface of the indicator disc so that the numeral changes by one whenever the manipulating lever is operated.

6. :

The medical stapler according to claim 1, wherein the counter device digitally indicates the number of staples driven from the driving mechanism.

7. :

The medical stapler according to claim 1, wherein the staples are accommodated in a cartridge removably attached to the stapler body, and

the driving mechanism drives the staple supplied to a driving section at the tip of the cartridge.

8. :

The medical stapler according to claim 7, wherein the counter device counts up the number of staples driven from the driving mechanism.

9. :

The medical stapler according to claim 7, wherein the counter subtracts the number of staples driven from the driving mechanism thereby to indicate the remaining number of staples counted down in the cartridge.

10. :

The medical stapler according to claim 7, wherein the counter device comprises an indicator disc that rotates in synchronism with an operation of the manipulating lever, and

a numeral is successively indicated on a peripheral surface of the indicator disc so that the numeral changes by one whenever the manipulating lever is operated.

11. :

The medical stapler according to claim 7, wherein the counter device digitally indicates the number of staples driven from the driving mechanism.
