Abstract

This surgical instrument has a clamping and holding member of special construction especially suited for use in circumcision operations involving the use of conventional hospital instruments such as a probe, scalpel, and hemostat, for completing the circumcision operation, while in the preferred form the instrument will involve the use in combination of two main portions, with one of these being the clamping and holding member, and the other a cutting member, with the two members pivotally connected together and guided in cooperative operating position, and when the two main portions are principally formed of plastic, same can be discarded at the end of the operation without need of sterilization for reuse.

Claims

1. A surgical instrument of the character described particularly adapted for use in the conducting of circumcision operations, which comprises a clamping member having two substantially parallel arms with faces longitudinally abutting each other and joined at one end by a hinge member and also joinable by a latching means at the other end, said arms having close-spaced, small, longitudinal interengaging grooves on their abutting faces with said grooves tightly fitting each other at least throughout the central portion of said arms when they are in latched position, at least one of said arms of said clamping member being slightly bowed at the central portion toward the other arm at said central portion with said other arm being so shaped as to contact said bowed portion to facilitate tight clamping said arms also having on one pair of mutually coplanar faces substantially in the central portion of same and on the junction of said abutting faces of same, a relatively wiDe angle deep recess with approximately half of same in each arm but not extending wholly through same.

2. A surgical instrument as set forth in claim 1, wherein at least one of said arms has guide means for holding said arms in parallel alignment during the final closing and latching of same.

3. A surgical instrument as set forth in claim 2, wherein said guide means is a pair of guiding ears on the opposite sides of one of said arms adjacent said latching means, for guiding said arms into proper position for latching.

4. A surgical instrument as set forth in claim 1, wherein stop means are provided adjacent at least one end of said arms in their abutting faces.

5. A surgical instrument as set forth in claim 1, wherein stop means are provided adjacent both ends of said arms in their abutting faces.

6. A surgical instrument as set forth in claim 2, wherein stop means are provided adjacent at least one end of said arms in their abutting faces.

7. A surgical instrument as set forth in claim 3, wherein stop means are provided adjacent both ends of said arms in their abutting faces.

8. A surgical instrument of the character described particularly adapted for use in the conducting of circumcision operations, which comprises a clamping member having two substantially parallel arms with faces longitudinally abutting each other and joined at one end by a hinge member and also joinable by a latching means at the other end, said arms also having one one pair of mutually coplanar faces substantially in the central portion of same and on the junction of said abutting faces of same, a relatively wide angle deep recess with approximately half of same in each arm but not extending wholly through same, wherein there is a cutting member with means pivotally mounting same on said clamping member at the hinge end of same, said means pivotally mounting said cutting member comprising an extension fitting and extending through the hinge member of said clamping member and having an outward tapering portion which firmly and tightly presses said cutting member onto the cutting member-engaging face of said clamping member.

9. A surgical instrument of the character described particularly adapted for use in the conducting of circumcision operations, which comprises a clamping member having two substantially parallel arms with faces longitudinally abutting each other and joined at one end by a hinge member and also joinable by a latching means at the other end, said arms also having on one pair of mutually coplanar faces substantially in the central portion of same and on the junction of said abutting faces of same, a relatively wide angle deep recess with approximately half of same in each arm but not extending wholly through same, wherein there is a cutting member with means pivotally mounting same on said clamping member at the hinge end of same, and said cutting member includes two arms jointed by a partial ring-shaped member and with said pivotal mounting means including an extension of said partial ring-shaped member fitting and extending through said hinge member of said clamping member.

10. A surgical instrument as set forth in claim 9, wherein said cutting member carries a cutting knife on one of its arms in position for closely fitting and movable over the cutting knife-engaging edge of the abutting faces of the arms of said clamping member to shear anything projecting from same.

11. A surgical instrument as set forth in claim 9, wherein said extension has on the outside of its free end an outward tapering portion which firmly and tightly presses said cutting member onto the cutting member-engaging face of said clamping member.

12. A surgical instrument as set forth in claim 9, wherein said clamping member and said cutting member have interengaging means at their hinge end for holding said cutting member substantially symmetrically located over said clamping member.

13. A surgical instrument as set forth in claim 10, wherein said exteNsion has on the outside of its free end an outward tapering portion which firmly and tightly presses said cutting member onto the cutting member-engaging face of said clamping member.

14. A surgical instrument as set forth in claim 10, wherein said clamping member and said cutting member have interengaging means at their hinge end for holding said cutting member substantially symmetrically located over said clamping member.

15. A surgical instrument as set forth in claim 9, wherein:

said cutting member carries a cutting knife on one of its arms in position for closely fitting and movable over the top edge of the abutting faces of the arms of said clamping member to shear anything projecting from same;

said extension has on the outside of its free end an outward tapering portion which firmly and tightly presses said cutting member onto the cutting member-engaging face of said clamping member;

said clamping member and said cutting member have interengaging means for holding said cutting member substantially symmetrically located over said clamping member; and

at least one of said arms of said clamping member is slightly bowed a major portion of its length toward the other arm to facilitate tight clamping substantially full length of same.

16. A surgical instrument as set forth in claim 15, wherein:

at least one of said arms of said clamping member has guide means for holding said arms in parallel alignment during the final closing and latching of same;

wherein stop means are provided adjacent at least one end of said arms in their abutting faces; and

wherein said cutting member arm carrying said cutting blade has adjacent its free end a guiding means engaging said clamping means for stabilizing and holding said blade in shearing position adjacent the blade-engaging face of said clamping member.

17. A surgical instrument as set forth in claim 1, wherein said deep recess is substantially conical.

18. A surgical instrument as set forth in claim 9, wherein said deep recess is substantially conical.

19. A surgical instrument as set forth in claim 8, wherein the arms of said clamping member are provided with close-spaced, longitudinal interengaging grooves on their abutting faces with said grooves tightly fitting each other at least throughout the central portion of said arms when they are in matched position.

20. A surgical instrument as set forth in claim 9, wherein the arms of said clamping member are provided with close-spaced, longitudinal interengaging grooves on their abutting faces with said grooves tightly fitting each other at least throughout the central portion of said arms when they are in matched position.
