When the existing trocar is in use, blocking of a trocar hole, difficult fixing, free trocar, pneumothorax and the like easily occur so as to influence the life of a patient. The trocar adopts the technical scheme that a trocar core penetrates through a cavity in a trocar sleeve to be arranged in the trocar sleeve; the front end of the trocar core is a trocar core head; a trocar core rod is connected with the rear of the trocar core head; and a trocar core handle is connected with the rear of the trocar core rod. The cavity is arranged in the trocar sleeve; the front end of the trocar sleeve is an oblique cone trocar head; two symmetrical flow guide holes are formed at the positions close to the trocar head; scales are marked on the tube wall of the trocar sleeve; the trocar sleeve is sheathed with a positioning plate; the rear part of the trocar sleeve is a trocar sleeve cap; a trocar sleeve cap cover is arranged at the rear end of the trocar sleeve cap; a flow guide port is arranged on the lateral surface of the trocar sleeve cap; and the flow guide port is a standard injector interface. In the scheme, the two flow guide holes are additionally formed at the front end of the trocar sleeve, so as to prevent unsmooth flow guide caused by blocking; a puncture needle is fixed at a fixing position through the positioning plate, so that the equipment is convenient to fix, and the stability is good; the operation is safe, simple and convenient; and the safety factor of the puncturing flow guide for the internal medicine is improved.
Description
Technical field
This utility model relates to the medical device technical field, is specifically related to a kind of internal medicine paracentesis trocar.
Background technology
Present puncture technique is widely used in clinical, as thoracentesis, abdominal paracentesis, joint puncture etc.Existing sleeve pipe puncture needle is made up of nook closing member and needle guard, is cavity in the needle guard, and nook closing member and needle guard front end are scalene cone, and the nook closing member diameter is consistent with needle guard cavity internal diameter, and nook closing member passes the needle guard internal cavity and is contained in the needle guard.
When using puncture,, when the opposing sense reduces, show and thrust the target cavity after point of puncture sterilization, the local anaesthesia puncture needle slowly being inserted.Keep chamber pressure this moment, and water conservancy diversion can be extracted puncture needle after going out certain quantity of fluid, and the part compresses, and makes the puncturing hole closure.
The shortcoming of common puncture needle has: pin hole in use takes place and stops up in puncture needle easily, and water conservancy diversion liquid can't be derived, and needs to repeat inserting needle, and the operation potential danger is increased; Puncture needle is difficult for fixing in the piercing process, easily run-bake-needle fault; Hydrops easily erupted when nook closing member was extracted out, operated wayward; After nook closing member was extracted out, outside air entered the operation cavity along needle guard, and negative pressure disappears in the cavity, easily formed the phenomenon that pneumothorax etc. influences patient's life.
Summary of the invention
For overcoming above-mentioned shortcoming, the purpose of this utility model provide a kind of water conservancy diversion unobstructed, be convenient to fix, internal medicine paracentesis trocar that handling safety is stable.Technical solutions of the utility model are:
Constitute internal medicine puncture needle of the present utility model by nook closing member 101 and needle guard 201, nook closing member 101 passes needle guard 201 internal cavities and is contained in the needle guard 201.Nook closing member 101 front ends are the diameter nook closing member head 102 consistent with needle guard 201 internal diameters, and nook closing member head 102 front ends are scalene cone; Nook closing member head 102 back are connected with nook closing member bar 103, and nook closing member bar 103 back are connected with nook closing member handle 104.In the needle guard 201 is cavity, and front end is the scalene cone syringe needle; Be provided with two symmetric pod apertures 202 near needle section, pod apertures 202 is ellipse or the Pedicellus et Pericarpium Trapae shape of the longitudinal axis along the needle guard direction; Needle guard 201 tube walls are marked with the graduation mark of indication paracentesis depth, are with on the needle guard 201 by the fixed location-plate 203 of swivel bolt, by observing the indication of puncture scale and the practical situation localised puncture degree of depth; Needle guard 201 rear ends be the needle guard medicated cap 204 of cavity in being provided with, and there is threaded needle guard cap 205 needle guard medicated cap 204 rear ends, needle guard cap 205 central authorities have be with sealing member with the isometrical circular hole of nook closing member bar 103 nook closing member bar 103 is passed; Needle guard medicated cap 204 sides are provided with flow-guiding mouth 206, and flow-guiding mouth 206 is the standard syringe interface.
Description of drawings:
Accompanying drawing 1 is this utility model structural representation;
Accompanying drawing 2 is this utility model nook closing member structural representation;
Accompanying drawing 3 is this utility model needle guard structural representation.
In the accompanying drawing: 101, nook closing member, 102, the nook closing member head, 103, the nook closing member bar, 104, the nook closing member handle, 201, needle guard, 202, pod apertures, 203, location-plate, 204, the needle guard medicated cap, 205, the needle guard cap, 206, flow-guiding mouth.
Beneficial effect:
This programme is used in 201 needle guard front ends and is provided with two longitudinal axis can effectively to prevent to stop up the water conservancy diversion that causes along the oval or rhombohedral pod apertures 202 of needle guard direction logical not smooth; By location-plate 203 puncture needle is fixed in fixed position, it is good that equipment is convenient to stability maintenance; Simple and safe operation has improved the safety coefficient of internal medicine puncture water conservancy diversion.
The specific embodiment:
Constitute internal medicine puncture needle of the present utility model by nook closing member 101 and needle guard 201, nook closing member 101 passes needle guard 201 internal cavities and is contained in the needle guard 201.Nook closing member 101 is the diameter nook closing member head 102 consistent with needle guard 201 internal diameters with front end, and nook closing member head 102 front ends are scalene cone; Nook closing member head 102 back are connected with nook closing member bar 103, and nook closing member bar 103 back are connected with nook closing member handle 104.In the needle guard 201 is cavity, and front end is the scalene cone syringe needle; Be provided with two symmetric pod apertures 202 near needle section, pod apertures 202 is ellipse or the Pedicellus et Pericarpium Trapae shape of the longitudinal axis along the needle guard direction; Needle guard 201 tube walls are marked with the graduation mark of indication paracentesis depth, are with on the needle guard 201 by the fixed location-plate 203 of swivel bolt, by observing the indication of puncture scale and the practical situation localised puncture degree of depth; Needle guard 201 rear ends be the needle guard medicated cap 204 of cavity in being provided with, and there is threaded needle guard cap 205 needle guard medicated cap 204 rear ends, needle guard cap 205 central authorities have be with sealing member with the isometrical circular hole of nook closing member bar 103 nook closing member bar 103 is passed; Needle guard medicated cap 204 sides are provided with flow-guiding mouth 206, and flow-guiding mouth 206 is the standard syringe interface.
