Definitions

  • ABSTRACT A surgical instrument for hysterectomy, which includes a C-shaped 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.
  • the present invention relates to surgical instruments and has particular reference to instruments for' hysterectomy or extirpation of the uterus made use of in gynecological practice.
  • scalpel or operative knife for performing hysterectomy and establishing a V-shaped cavity in the amputational stump thereof is far from convenient since pathologically changed uterine tissue has an exaggerated density and is therefore hardly amenable to being cut.
  • a surgical instrument for hysterectomy which includes a C-shaped body whose cantilevered sections form a gap open on one side to accommodate the uterus portion to be excised a locking bar adapted to interact with the ends of the cantilevered body sections and a knife provided with an actuator to impart reciprocating motion thereto along the guide slots of the body and of the locking bar in a 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 is shaped as a hollow right truncated trihedral prism with the face edges that overlook the knife-supporting body section being cutting edges and interacting with the correspondingly shaped faces of said knife-supporting body 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 the other two knife faces.
  • Such an instrument is simple in design and provides a convenient approach to the portion of the uterus to be excised during supravaginal hysterectomy.
  • the instrument allows fixing of the uterine body during operation, cuts down operational time by virtue of the concurrent extirpation of the uterus and formation of an equilateral V-shaped cavity in the stump thereof, and ensures guided knife movement while reducing cutting force.
  • the lateral cantilevered sections of a the C-shaped body be provided with cavities to accommodate the knife in its extreme positions, thereby excluding any possibility of injuring the adjacent tissues when approaching and applying the instrument to the portion of the uterus to be excised or withdrawing the instrument from the operative area upon extirpation of the uterus.
  • FIG. 1 illustrates a surgical instrument for hysterectomy according to the invention, in an elevational view, partly in cross-section;
  • FIG. 2 is partly sectional plan view of a surgical instrument for hysterectomy, according to the invention.
  • FIG. 3 is a section taken along the line III--III in FIG.
  • FIG. 4 illustrates the application technique of a surgical instrument according to the invention, in supravaginal hysterectomy
  • FIG. 5 illustrates the uterus while fixed in a surgical instrument by means of the locking bar, according to the invention
  • FIG. 6 illustrates the uterus extirpation procedure with the use of a surgical instrument, according to the invention
  • FIG. 7 illustrates the excised uterus and the V- shaped cavity in the uterine stump resulting from the operation of hysterectomy by using a surgical instrument, according to the invention.
  • FIG. 8 illustrates the technique of suture application to the uterine stump.
  • the surgical instrument for hysterectomy includes two major structural components, viz., a knife 1 (FIGS. 1, 2) and a C-shaped body 2.
  • the knife 1 is shaped as a hollow night truncated trihedral prism whose face 3 is lanceolate in shape if viewed from above, whereas its pointed end is advanced with respect to the cutting edges of two other knife faces 4 (FIG. 3).
  • the knife 1 is connected through a pusher 5 (FIG. 1) to the actuator formed as a screw 6 interacting with a nut 7.
  • the screw 6 is located in a cantilevered section 8 (FIG. 2) of the body 2 and by means of the nut 7 causes the knife 1 to displace from one cantilevered section 8 of the body 2 to another such section 9, the cantilevered section 9 of the body 2 serving as a support for the knife during cutting and having faces 9' corresponding in shape to faces 3 and 4 of the knife 1 and adapted to interact therewith during cutting.
  • the knife 1 has projections (FIG. 3) with which it can travel along a guide slot 11 of the body 2 and a guide slot 12 of a locking bar 13.
  • the knife 1 When in the initial position the knife 1 (FIG. 1) occupies a cavity a provided in the cantilevered section 8 of the body 2 so that the cutting edges of its faces 3 and 4 are completely buried in the cavity a which precludes any injury to the adjacent tissues when approaching and applying the instrument to. the uterine portion to be excised.
  • the knife 1 When in its terminal position the knife 1 occupies a cavity b provided in the section 9 of the body 2 so that the cutting edges of the knife faces 3 and 4 are likewise completely buried in the cavity b which prevent any injury to the adjacent tissues when withdrawing the instrument from the operative area upon extirpation of the uterus.
  • the locking bar 13 (FIG. 2) is located in the section 8 of the body 2 so as to freely engage the opening in the section 9 of the body 2. When in its extreme positions the locking bar 13 is fixed in place by means of a spring-loaded retainer 14.
  • the surgical instrument for hysterectomy operates as follows:
  • the knife 1 is caused to move along the guide slots 11 and 12 (FIG. 3) of the body 2 and the locking bar 13, respectively, towards the cantilevered section 9 (FIG. 1) of the body 2, said section serving as a support for the knife 1 during cutting. While moving the knife 1 performs extirpation of the uterus 16 (FIG. 6) with its lanceolate face 3 and establishes an equilateral V-shaped cavity (FIG. 7) in a stump 17 of the uterus with its two other faces 4 (FIG. 6).
  • the instrument effects fixing of the uterus being 0 erate upon by 'ine ns of the lock'n ar 13 which 0 verst e pen side 0 the gap d, t e e yrestrlctmg the radial displacement of the uterus being extirpated, and reduces the operational time by combining the process of hysterectomy with I the simultaneous establishing of an equilateral V-shaped cavity in the stump thereof.
  • the instrument ensures'a guided movement of the knife 1.
  • 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.
