Description
Technical field
This utility model patent relates to the lancet device that a kind of epidural anesthesia uses, be specifically related to a kind of not damaged epidural catheter puncture needle, during routine epidural Anaesthesia each for hospital clinical mechanism row, human body epidural is punctured and injectable drug, belong to technical field of medical instruments.
Background technology
The anesthesia spinal needle of existing market extensive use, in use, medical worker often can encounter when exiting anesthetic tube, and pin sword cuts off conduit phenomenon.Anesthetic tube can remain in patient after disconnecting, and under normal circumstances, can implement second operation and take out.For this reason, cause very large physical pain to sufferer, too increase the risk of operation.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of not damaged epidural catheter puncture needle of easy and simple to handle, safe and effective, angle adjustable.
The purpose of this utility model is achieved through the following technical solutions: not damaged epidural catheter puncture needle; comprise needle tubing, the needle stand be connected with needle tubing tail end, the pin sword of placing anesthetic tube; described pin sword is inclined at needle tubing head; it is characterized in that; described syringe intracavity is provided with protective sleeve; described needle tubing head is provided with guiding tongue, and guiding tongue is arranged on the needle tubing tube wall relative with pin sword position.
Described needle tubing head is the arc-shaped structure upwards extended, and pin sword is arranged on arc-shaped structure end.
Described protective sleeve is FEP protective sleeve.
One end of described protective sleeve extends to needle stand outside through needle stand inner chamber, and the other end extends needle tubing outside.
The other end of described protective sleeve extends needle tubing outside and is longer than needle tubing 1-1.5mm.
The inner chamber of described needle stand is taper hole structure.
Described needle stand front portion is provided with draw-in groove.
Described guiding tongue is bar shaped shell fragment, and the needle tubing tube wall place arranging guiding tongue is provided with the installing port matched with bar shaped shell fragment, and bar shaped shell fragment one end is connected with the medial wall of installing port.
Described needle tubing is that medical stainless steel is made.
Described protective sleeve is connected with needle interior wall is cementing.
This utility model has put tubulose FEP protective sleeve (FEP and fluorinated ethylene propylene copolymer) at syringe intracavity, its one end extends to needle stand outside through needle stand inner chamber, can be convenient to anesthetic tube accurately insert in protective sleeve, protective sleeve is placed between anesthetic tube and needle tubing; The other end extends needle tubing outside (namely the other end extends to pin blade position), and this end is longer than needle tubing 1-1.5mm, and such medical worker, when exiting anesthetic tube, can prevent anesthetic tube from contacting with pin sword, thus prevents pin sword from cutting off anesthetic tube phenomenon.What contrast that traditional anesthesia spinal needle adopts at the anesthesia surgery that sufferer neck, breast, waist, each intersegmental gap of sacrum are carried out puts tube method, not damaged anesthesia spinal needle designed by this utility model puts pipe, can effectively avoid medical worker to draw disconnected segmental epidural catheter when moving back pipe.
Guiding tongue is arranged on the needle tubing tube wall relative with pin sword position (pin sword upward; guiding tongue is arranged on the needle tubing tube wall that is positioned at below pin sword); guiding tongue is bar shaped shell fragment; and to needle tubing inner projection; the needle tubing tube wall place arranging guiding tongue is provided with the installing port matched with bar shaped shell fragment; bar shaped shell fragment one end is connected with the medial wall of installing port, and the protruding part (i.e. protective sleeve and pin sword contact position) of extending needle tubing at protective sleeve like this forms a guiding tongue to needle tubing inner projection.In actual use, take this protective measure, guiding tongue can play the effect regulating direction, stable steering point, control withdraw of the needle dynamics when anesthetic tube is inserted, thus ensure that product safety in utilization and effectiveness.
This utility model structure is simple, and technical characterstic is distinct, and after making to put caudal block, solution is moved back pin sword in pipe process and cut off conduit phenomenon.The angle of this utility model scalable anesthetic tube, product operation is easy, improves Product Safety, avoids clinical accident to occur, cause secondary injury to sufferer.

Detailed description of the invention
Not damaged epidural catheter puncture needle, comprises needle tubing 1, the needle stand 2 be connected with needle tubing tail end, the pin sword 4 of placing anesthetic tube 7.The inner chamber of needle stand 2 is taper hole structure, and needle stand front portion is provided with draw-in groove, and needle tubing is that medical stainless steel is made.
Pin sword is inclined at needle tubing head, and needle tubing 1 head is the arc-shaped structure 6 upwards extended, and pin sword 4 is arranged on arc-shaped structure end, and this structure can be convenient to anesthetic tube and find and execute pin position accordingly and anaesthetize.
Syringe intracavity is provided with FEP protective sleeve 3, and protective sleeve is placed between anesthetic tube and needle tubing.Protective sleeve 3 is connected with needle tubing 1 inwall is cementing or is connected by other connected modes, and it is outside that its one end extends to needle stand 2 through needle stand inner chamber, and the other end extends needle tubing 1 outside and is longer than needle tubing 1-1.5mm(i.e. this end to pin blade position extension).The arranging of protective sleeve is on the one hand convenient to anesthetic tube and is entered in needle tubing, effectively avoids medical worker to draw disconnected anesthetic tube when moving back pipe on the other hand.
Needle tubing head is provided with the guiding tongue 5 to needle tubing inner projection, and guiding tongue is arranged on the needle tubing tube wall relative with pin sword position.Guiding tongue 5 is bar shaped shell fragment, and the needle tubing tube wall place arranging guiding tongue is provided with the installing port matched with bar shaped shell fragment, and bar shaped shell fragment one end is connected with the medial wall of installing port.The tongue that leads can play the effect of the direction of adjustment anesthetic tube, stable steering point, control withdraw of the needle dynamics when anesthetic tube is inserted.
Not damaged epidural catheter puncture needle designed by this utility model, comprising cross section is the protective sleeve that the circular bar-shaped needle tubing of all kinds of pipes and all kinds of material are made.Needle stand front portion is provided with draw-in groove, and needle tubing one end is connected with guiding tongue, and guiding tongue is to needle tubing inner projection.During use, epidural catheter (anesthetic tube) penetrates in needle tubing from needle stand afterbody taper hole, when touching guiding tongue near ejector sleeve to pin sword, has obvious resistance, and guiding tongue plays ejector sleeve balance direction, grasps degree of depth effect.When anesthesia retreats pipe, guiding tongue plays the effect regulating and move back pipe direction, and protective sleeve can prevent segmental epidural catheter from contacting with needle tube edge and form pipe cutting, causes disconnected manage-style danger.This utility model to product technology require high, Product Safety and effectiveness high, simple to operate, drastically increase clinical safety, reduce in operation process the risk of cutting off anesthetic tube.
