Surgical instrument

Claim 2

A surgical instrument of the character described particularly adapted for use in the conducting of circumcision operations, which comprises an integral clamping member having two arms with clamping faces longitudinally abuttable with each other, a partial ring-shaped hinge means integrally connected to one end of each of said arms and permitting them to pivot with respect to each other while spring-biasing them to a normally open position, clamping lock means at the end of said clamping faces proximal to said hinge means, additional clamping lock means provided at the end of said clamping faces distal to said hinge means, thereby permitting said arms to be locked in positive clamping engagement at both ends of said clamping faces, and a cutting member pivotally mounted at the hinge means of said clamping member, and wherein said cutting member has an extension fitting extending through the partial ring-shaped hinge means of said clamping member, and having a flange at the end of said extension for retaining said extension within the partial ring-shaped member of said clamping means.

Claim 3

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

Claim 4

A surgical instrument as set forth in claim 1, wherein said guide means is a pair of guiding ears positioned on opposite sides of one of said arms aDjacent said latching means.

Claim 5

A surgical instrument as set forth in claim 1, wherein stop means is provided adjacent said proximal clamping lock means, thereby preventing the foreskin from being pushed toward said hinge means out of the clamping area of said clamping member when the latter is being clamped.

Claim 6

A surgical instrument according to claim 1, wherein said arms are beveled at said clamping faces thereby providing a trough-like recess adapted to position and protect the glans penis during the operation.

Claim 7

A surgical instrument according to claim 1, wherein said clamping means has supporting feet to elevate same for ease of grasping.

Claim 8

A surgical instrument of the character described particularly adapted for use in the conducting of circumcision operation, which comprises a clamping member having two arms with clamping faces longitudinally abuttable with each other, hinge means comprising a circular hook provided in one of said arms and a mating circular hook provided at the other arm pivotally engaging the hook of said first arm, one of said hooks being slidably mounted over the other in coplanar and coaxial arrangement, clamping lock means at the end of said clamping faces proximal to said hinge means, and additional clamping lock means provided at the end of said clamping faces distal to said hinge means, thereby permitting said arms to be locked in positive clamping engagement at both ends of said clamping faces, and a cutting member having a pivot pin member at one end pivotally and coaxially engaged by the hook of said first arm, said pivot pin member being provided with flanges at the ends thereof, thereby maintaining said hooks in axial relationship thereto, whereby said two arms and said cutting member are pivotal with relation to each other.

Claim 9

A surgical instrument of the character described particularly adapted for use in the conducting of circumcision operation, which comprises a clamping member having two arms with clamping faces longitudinally abuttable with each other, hinge means comprising a circular hook provided in one of said arms and a mating circular hook provided at the other arm pivotally engaging the hook of said first arm, one of said hooks being slidably mounted over the other in coplanar and coaxial arrangement, clamping lock means at the end of said clamping faces proximal to said hinge means, and additional clamping lock means provided at the end of said clamping faces distal to said hinge means, thereby permitting said arms to be locked in positive clamping engagement at both ends of said clamping faces, and a cutting member having a pivot pin member at one end pivotally and coaxially engaged by the hook of said first arm, said pivot pin member being provided with flanges at the ends thereof, thereby maintaining said hooks in axial relationship thereto, whereby said two arms and said cutting member are pivotal with relation to each other.
