Abstract
The utility model provides a medical puncturing and positioning needle which comprises a hook steel wire puncturing and positioning needle, a needle handle and a positioning needle sleeve, and is characterized in that the hook steel wire puncturing and positioning needle is provided with three positioning needle hooks; the inclined angle between each two needle hooks is 120 degrees; a rubber or emulsion seal ring is added in a part of the hook steel wire puncturing and positioning needle on the needle handle, which is inserted into a sleeve opening; a mark is added at one end of the hook steel wire puncturing and positioning needle in the needle handle; the position where the mark is added is the position where the hooked steel wires are just folded in the sleeve opening completely. The anchoring performance is enhanced, and the possibility that the positioning needle falls off is reduced through changing from the conventional form that the two steel wires are wound around the puncturing needle and after the two steel wires are released, the puncturing needle adopts a double-hook structure to the form that the puncturing needle is woven by three steel wires, and after the steel sires are released, the puncturing needle adopts a three-hook structure, and the inclined angle between any two adjacent hooks is 120 degrees. A sealing device is additionally arranged to reduce and relieve pneumothorax. The mark is added on the hook steel wire puncturing and positioning needle, so that the defect that an operator need to identify the puncturing needle by himself due to no mark on the puncturing needle is overcome, and the operation is relatively convenient.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of medical thrust positioning needle.
Background technology
Behind the lung lesser tubercle lower buckle steel wire puncture localization needle puncture of preoperative CT guiding location, under thoracoscope, excising target lesion, is to process at present the nodular main policies of lung.The buckle steel wire puncture localization needle using mostly at present is double hook or single hook.Its problem existing in using is: 1, positioning needle easily comes off; 2, after puncture, easily form pneumothorax.Falling-off Cause Analysis: 1, existing puncture localization needle initial designs is to be applied to breast puncture location, thoracic surgeon expanded and was applied to lung tissue puncture location afterwards, because mammary gland tissue and lung tissue density, quality are different, so cause easily coming off when lung damages tissue penetration location; 2, after puncture, the reason one of formation pneumothorax is to be leaked gas to thoracic cavity by damage lung tissue, and another is former because present puncture localization needle exists gap between sleeve pipe and buckle steel wire, and it is negative pressure that puncture enters in Hou，Yin thoracic cavity, thoracic cavity, can suck air form pneumothorax to thoracic cavity.
Utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of medical thrust positioning needle is provided.
The technical solution of the utility model is: medical thrust positioning needle comprises buckle steel wire puncture localization needle, needle handle, positioning needle sleeve pipe, it is characterized in that buckle steel wire puncture localization needle has three location pinhocks, angle each other 120 between three location pinhocks.
On described needle handle, buckle steel wire puncture localization needle interts and adds rubber or latex sealing ring into sleeve opening place.
On described buckle steel wire puncture localization needle, label, tagged position is just to draw the position into sleeve opening completely at buckle steel wire.
This utility model, by two present steel wire windings, is double hook after discharging, and changes three braided steel wires into, after discharging, for being mutually three hooks at 120 degree angles, increases grappling, reduces positioning needle and comes off.Add sealing device, the generation that can reduce, alleviate pneumothorax.On buckle steel wire puncture localization needle, label, overcome the defect that puncture needle is recognized by patient oneself without sign, make more convenient operation.
Accompanying drawing explanation
Fig. 1 is medical thrust positioning needle structural representation of the present utility model.
Fig. 2 is medical thrust positioning needle structural representation of the present utility model (location pinhock just draws in completely in sleeve pipe).
In figure, 1-buckle steel wire puncture localization needle, 2-needle handle, 3-buckle steel wire puncture localization needle penetrates positioning needle sleeve pipe part, 4-positioning needle sleeve pipe, 5,6,7-locates pinhock, 8-rubber or latex sealing ring, 9-labelling.
The specific embodiment
As shown in Figure 1, medical thrust positioning needle of the present utility model comprises: buckle steel wire puncture localization needle 1, needle handle 2, positioning needle sleeve pipe 4, buckle steel wire puncture localization needle has between the pinhocks of 5,6,7, three of pinhocks location, three location angle each other 120.On needle handle, buckle steel wire puncture localization needle 1 interts and adds rubber or latex sealing ring into sleeve opening place.Buckle steel wire puncture localization needle 1 adds labelling in one end of needle handle 2, and tagged position is to label in the position of just drawing in completely in sleeve pipe when buckle steel wire, as shown in Figure 2.
Claims (3)
