Abstract
Abstract A device for putting clips on blood vessels comprises a tubular member moving with respect to a shackle and a guide or working rod inserted into the cavity of the tubular member. The method of treating brain aneurysms consists in that a hole is cut out in the patient's cranium under local anesthesia, a stereotaxic apparatus and the proposed device are installed in the hole, a guide rod is installed in the tubular member of the device, and the latter is brought to the part of the vessel to be clipped. The guide rod is then removed from the tubular member, and the working rod holding the clip is inserted instead. The clip is pushed out from the cavity of the tubular member and the vessel is clipped. The clip is now released from the grip, and the tubular member together with the working rod are removed from the operative hole.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
219 words
A device for putting clips on vessels, comprising: a shackle; a tubular housing member having a tapered end and mounted on said shackle and being movable along an axis; a removable and threaded guide rod adapted to be inserted into the cavity of said tubular housing member for guiding said tubular housing member to the vessel to be clipped; a working rod including a tubular member, and a grip having means for holding said clip, also adapted to be inserted into the cavity of said tubular housing member; said grip being positioned within said tubular member by a spring controllable by an adjusting knob; said working rod being disposed coaxial with respect to said tubular housing member and movable along said axis; each of said working rod and said tubular housing member having threaded means and associated adjusting wheels mounted in said shackle for controlling the axial movements thereof; said adjusting wheel for said working rod also used for controlling the axial movement of said guide rod; and each of said threaded guide rod and said working rod having a rule cooperatively associated with said shackle for respectively monitoring the depth of said guide rod and for setting the point at which the jaws of said clip are opened prior to clipping and releasing said clip onto said vessel.

A device for putting clips on vessels, comprising: a shackle; a tubular housing member having a tapered end and mounted on said shackle and being movable along an axis; a removable and threaded guide rod adapted to be inserted into the cavity of said tubular housing member for guiding said tubular housing member to the vessel to be clipped; a working rod including a tubular member, and a grip having means for holding said clip, also adapted to be inserted into the cavity of said tubular housing member; said grip being positioned within said tubular member by a spring controllable by an adjusting knob; said working rod being disposed coaxial with respect to said tubular housing member and movable along said axis; each of said working rod and said tubular housing member having threaded means and associated adjusting wheels mounted in said shackle for controlling the axial movements thereof; said adjusting wheel for said working rod also used for controlling the axial movement of said guide rod; and each of said threaded guide rod and said working rod having a rule cooperatively associated with said shackle for respectively monitoring the depth of said guide rod and for setting the point at which the jaws of said clip are opened prior to clipping and releasing said clip onto said vessel.
Claim 3
Dependent Claim
80 words
The device according to claim 1, wherein said threaded means comprising a first threaded sleeve secured on said tubular housing member and mounted in said shackle and a second threaded sleeve secured on said tubular member and adapted to be mounted on said shackle in coaxial alignment with said tubular housing member, and said adjusting wheels being in the form of threaded nuts engageable with said threaded sleeves in order to move said tubular housing member and said working rod.
Claim 4
Dependent Claim
39 words
The device according to claim 2, further including a sleeve in said shackle coaxially disposed about said first sleeve and a fixing screw located between said sleeve and said first sleeve for preventing the mutual rotation of said sleeves.
