Claims
- 1. A disconnectable vaginal speculum for observing the vagina of a female patient and for performing procedures in connection with treatments and measurements, comprising:
a first blade member having a longitudinal direction, a distal end and a proximal end with a first guide formed on said proximal end in a direction perpendicular to said longitudinal direction; a sliding member slidingly guided in said first guide, said sliding member having first pivot connection means on one end and sliding member fixation means on the end opposite to said one end; a second blade member having second pivot connection means for pivotally connecting and disconnecting said second blade member to and from said sliding means without removing said disconnectable vaginal speculum from said vagina; said first blade member and said second blade member each consisting of a guide portion, which is not inserted into vagina of said female patient during the use of said disconnectable vaginal speculum, and a removable blade insertable into vagina of said female patient, said guide portion having a second guide parallel to said longitudinal direction, said removable blade being slidingly and removably inserted into said second guide; and means for fixing position of said second blade member with respect to said first blade member in any position to which said second blade member can be turned with the use of said pivot connection.
- 2. The speculum of claim 1, wherein said speculum is made of a transparent material.
- 3. The speculum of claim 2, further comprising measurement means for performing said measurements, said measurement means comprising a measurement scale formed on said removable blade.
- 4. The speculum of claim 1, further comprising blade turning means formed in said guide portion of said second blade member for turning said removable blade of said second blade member around an axis extending in said longitudinal direction.
- 5. The speculum of claim 3, further comprising blade turning means formed in said guide portion for turning said removable blade around an axis extending in said longitudinal direction.
- 6. The speculum of claim 1, wherein said first pivot connection means is made as a pair of L-shaped grooves and said second pivot means is made as a pair of pins slidingly insertable into said pair of L-shaped grooves, respectively.
- 7. The speculum of claim 3, wherein said first pivot connection means is made as a pair of L-shaped grooves and said second pivot means is made as a pair of pins slidingly insertable into said pair of L-shaped grooves, respectively.
- 8. The speculum of claim 4, wherein said blade turning means comprises a longitudinal slot formed in said guide portion parallel to said longitudinal direction and at least one circumferential slot which is perpendicular to said longitudinal slot formed in said guide portion of said second blade member and intersects therewith, said removable blade of said second blade member having a guide element which is rigidly connected to said removable blade of said second blade member and which can be guided in said longitudinal slot and in said circumferential slot.
- 9. The speculum of claim 5, wherein said blade turning means comprises a longitudinal slot formed in said guide portion parallel to said longitudinal direction and at least one circumferential slot which is perpendicular to said longitudinal slot formed in said guide portion of said second blade member and intersects therewith, said removable blade of said second blade member having a guide element which is rigidly connected to said removable blade of said second blade member and which can be guided in said longitudinal slot and in said circumferential slot.
- 10. The speculum of claim 6, wherein said blade turning means comprises a longitudinal slot formed in said guide portion parallel to said longitudinal direction and at least one circumferential slot which is perpendicular to said longitudinal slot formed in said guide portion of said second blade member and intersects therewith, said removable blade of said second blade member having a guide element which is rigidly connected to said removable blade of said second blade member and which can be guided in said longitudinal slot and in said circumferential slot.
- 11. The speculum of claim 7, wherein said blade turning means comprises a longitudinal slot formed in said guide portion parallel to said longitudinal direction and at least one circumferential slot which is perpendicular to said longitudinal slot formed in said guide portion of said second blade member and intersects therewith, said removable blade of said second blade member having a guide element which is rigidly connected to said removable blade of said second blade member and which can be guided in said longitudinal slot and in said circumferential slot.
- 12. The speculum of claim 1, wherein means for fixing position of said second blade member with respect to said first blade member comprises a projection with ratchet teeth formed on said sliding part and a projection with a pawl on said guide portion for engagement with said ratchet teeth.
- 13. The speculum of claim 8, wherein means for fixing position of said second blade member with respect to said first blade member comprises a projection with ratchet teeth formed on said sliding part and a projection with a pawl on said guide portion for engagement with said ratchet teeth.
- 14. The speculum of claim 9, wherein means for fixing position of said second blade member with respect to said first blade member comprises a projection with ratchet teeth formed on said sliding part and a projection with a pawl on said guide portion for engagement with said ratchet teeth.
- 15. The speculum of claim 10, wherein means for fixing position of said second blade member with respect to said first blade member comprises a projection with ratchet teeth formed on said sliding part and a projection with a pawl on said guide portion for engagement with said ratchet teeth.
- 16. The speculum of claim 11, wherein means for fixing position of said second blade member with respect to said first blade member comprises a projection with ratchet teeth formed on said sliding part and a projection with a pawl on said guide portion for engagement with said ratchet teeth.
- 17. The speculum of claim 1, wherein said first blade member has a distal end with a first semi-lens and said second blade member has a distal end with a second semi-lens, said first blade member and said second blade member can be turned with the use of said pivotal connection into a closed state in which said first semi-lens and said second semi-lens form a complete lens.
- 18. The speculum of claim 4, wherein said first blade member has a distal end with a first semi-lens and said second blade member has a distal end with a second semi-lens, said first blade member and said second blade member can be turned with the use of said pivotal connection into a closed state in which said first semi-lens and said second semi-lens form a complete lens.
- 19. The speculum of claim 6, wherein said first blade member has a distal end with a first semi-lens and said second blade member has a distal end with a second semi-lens, said first blade member and said second blade member can be turned with the use of said pivotal connection into a closed state in which said first semi-lens and said second semi-lens form a complete lens.
