Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
An endoscope instrument incorporating an elongate insertion sheath (2) insertable through a body cavity, incorporating an observation optical system, an illuminating optical system (7) with an eyepiece (11), and a forceps channel (13) capable to accept and insert an operational tool from the outside via an intermediate control body (3) which carries said insertion sheath and said eyepiece (11) into the body cavity in the axial direction of said elongate insertion sheath, characterised in that branched entry ports (16, 28) are provided at the rear end of the forceps channel whereby a plurality of passages (14, 15) communicate with said forceps channel to permit the concurrent insertion of a number of tools such as an ovum picker and a clamping forceps through said forceps channel, and at least one of said passages being provided with means (26) for holding and securing an operational tool or the like, when inserted therethrough.
Claim 2
Dependent Claim
150 words
An endoscope instrument incorporating an elongate insertion sheath (2) insertable through a body cavity, incorporating an observation optical system, an illuminating optical system (7) with an eyepiece (11), and a forceps channel (13) capable to accept and insert an operational tool from the outside via an intermediate control body (3) which carries said insertion sheath and said eyepiece (11) into the body cavity in the axial direction of said elongate insertion sheath, characterised in that branched entry ports (16, 28) are provided at the rear end of the forceps channel whereby a plurality of passages (14, 15) communicate with said forceps channel to permit the concurrent insertion of a number of tools such as an ovum picker and a clamping forceps through said forceps channel, and at least one of said passages being provided with means (26) for holding and securing an operational tool or the like, when inserted therethrough.
Claim 3
Dependent Claim
38 words
An endoscope ovum picker as claimed in Claim 1, characterised in that each said means for holding and securing said tool are sealed by a stop-cock (27, 69, 72, 142) and aligned, finely- apertured end-caps (16, 29, 137).
Claim 4
Dependent Claim
70 words
An endoscope ovum picker as claimed in Claim 1 or Claim 2, characterised in that the main body member at the rear end of said insertion sheath has a first mouthpiece (16) in alignment with said insertion sheath, a second mouthpiece (28) branched obliquely, and an endoscopic eyepiece (11) attached obliquely backwards, said passages (14, 15) each having stop-cocks and passage (15) having a port for gas or saline fluid.
Claim 5
Dependent Claim
127 words
An elongate tool for use in an instrument as claimed in any preceding Claim for picking up the ovum when inserted through a channel of said endoscope, comprising a fine hollow member (55, 125) with a convergent tip (59,129), provided with a small hole (60, 130) aligned with its channel a sharp-tipped sheath tube (53, 123) telescoping said fine hollow member axially and relatively thereto, an aspirating needle (52, 151) for picking up the ovum capable to be displaced axially within said fine hollow member in said sheath tube so that it can extend through said small hole and capable to pick up the ovum by its aspiration, and means for fixing detachably said needle in said fine hollow member for aspirating and picking up the ovum.
Claim 6
Dependent Claim
72 words
A tool as claimed in Claim 4, characterised in that said means for fixing said means for aspirating and picking up the ovum are designed so that the effective diameter of the inserting hole is variable by forming a split groove inside a contact member that embraces said means for aspirating and picking up the ovum, and pressing upon said member to narrow said inserting hole by pivotal motion of a lever.
