((21.y 12s-347) This invention is a noVel improvement in but said end being beveled and sharpened as at surgical needles particularly adapted for taking i to pierce the nesn. The inner member 3 has the internal pressures of the intra-pleural i' a transverse opening 5 therethrough adapted to other cavities of a patient, the needle having register with the perforations `2 in the outer means for Cutting through the esh and means member I in one position. The inner member 5 Operable to open a passage through the needle 3 carrying. the skin piercing pointl 4 projects to a suitable pressure recording apparatus, beyond the end of the outer member I while Whereby by using tWO such needles, injeeted into piercing the iiesh, and when so projected the the respective intra-pleural cavities between the holes 5 and 2 in the two members are cut of lungs and the Chest Walls at both sides of a register. When however the needle has been 10 patient, the pressures in both cavities may be injected into the patient the inner member 3 is reeordedadjusted as hereinafter described to retract the The needles may be connected by rubber tubsharp end 4 within the outer member I, to preing with the apparatus for graphically recording vent injury to the; patient, and to bring the such pressures for determining the differences in perforetions 5 and 2 into register, the inner 15 pressures. Also the needles may be used in member 3 having a bore 6 extending from the determining the pressures in cavities other than perferatiens 5 to the inner `end thereof and the intra-pleural CaVities of a patientleading into a duct I in a lateral extension 8 Other minor objeets of the inVention Will be to which is connected a combined valve and hereinafter set forth. hose coupling member 9 connected with hose H 20 I will explain the invention With reference to '(Fig. 1).y Preferably the inner end of the outer the accompanying drawing Whieh illustrates One member I is enlarged as at I a and has a bayonet praetleal embodiment thereof to enable others slot I0 therein adapted to receive a bayonet lug familiar with the art to adopt and use the same; on the inner member 3, the slot l0 being of and Will summarize in the Claims the noVe1 such length that when the bayonet lug II is 25 features of construction, and novel combinations et the inner end 0f the 5101; lo the Cutting point of parts, for which protection is desired. 4 Wi11 be projected beyond the outer member I In said drawing: the proper amount.

3. A surgical needle, comprising `an outer'V tubular member having a perforation; an inner tubular member having a flesh cutting kniferand having a perforation adapted to register with that in the outer member; means whereby in one position of the inner member the knife will project beyond the outer member and the perforations will be out of register, and in another position of the inner member the knife will be retracted within the outer member and the perforations will register.
