Abstract

Abstract A surgical instrument for hysterectomy, which includes a Cshaped body, the cantilevered sections thereof forming a gap open on one side to accommodate the uterine portion being excised, a locking bar adapted to interact with the ends of the cantilevered body sections, and a knife. The knife is free to move along the guide slots of the body and the locking bar in the direction from one of the cantilevered body sections to the other, one of said cantilevered body sections serving as a support for the knife during cutting. The knife has the shape of a hollow right truncated trihedral prism, wherein the edges of the faces that overlook the knife-supporting body section are cutting edges adapted to interact with the correspondingly-shaped faces of said supporting section. One of the knife faces is lanceolate in shape when viewed from above, its pointed end being advanced with respect to the cutting edges of other two knife faces.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 186 words
A surgical instrument for hysterectomy comprising: a C-shaped body having cantilevered sections which form a gap open on one side to accommodate an excised portion of a uterus; a locking bar extending between the ends of said cantilevered sections of the body to close said gap; a guide slot in said body; a guide slot in said locking bar; a knife located in and capable of free displacement along said guide slots of the body and of the locking bar from one of said cantilevered body sections toward the other, one of said cantilevered body sections serving as a support for said knife during cutting, said knife being shaped as a hollow right truncated trihedral prism, the edges of the faces thereof that oppose said supporting body section being cutting edges, the faces of said supporting body section corresponding by the shape to said cutting edges of the knife and serving to interact therewith during cutting, one of said knife edges being lanceolate in shape, and being advanced with respect to the cutting edges of the other two said faces; and an actuator for said knife.
Claim 2
Dependent Claim 186 words
A surgical instrument for hysterectomy comprising: a C-shaped body having cantilevered sections which form a gap open on one side to accommodate an excised portion of a uterus; a locking bar extending between the ends of said cantilevered sections of the body to close said gap; a guide slot in said body; a guide slot in said locking bar; a knife located in and capable of free displacement along said guide slots of the body and of the locking bar from one of said cantilevered body sections toward the other, one of said cantilevered body sections serving as a support for said knife during cutting, said knife being shaped as a hollow right truncated trihedral prism, the edges of the faces thereof that oppose said supporting body section being cutting edges, the faces of said supporting body section corresponding by the shape to said cutting edges of the knife and serving to interact therewith during cutting, one of said knife edges being lanceolate in shape, and being advanced with respect to the cutting edges of the other two said faces; and an actuator for said knife.
Claim 3
Dependent Claim 35 words
A surgical instrument as claimed in claim 1, wherein provision is made for interior cavities located in said cantilevered sections of the C-shaped body, said cavities serving to accommodate said knife in its extreme positions.
