Description

Ventricles of the brain peritoneal shunt abdominal paracentesis cone

Technical field

Ventricles of the brain peritoneal shunt abdominal paracentesis cone belongs to medical instruments field, is specifically related to a kind of shunt pipe enterocoelia end implant device.

Background technology

In the ventriculo-peritoneal shunt operation, it is to insert by abdominal that the abdominal end of isocon is inserted Intraabdominal general operation method, wound is large, operating time is long, the post-operative recovery time is long, and easily causing the complication of abdominal, for example infection of incisional wound is placed in recent years the isocon abdominal end and has been overcome the problems referred to above under peritoneoscope, but the device therefor complex structure, inconvenient operation.

Summary of the invention

The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of ventricles of the brain peritoneal shunt abdominal paracentesis simple in structure cone is provided.

The technical scheme that its technical problem that solves this utility model adopts is: this ventricles of the brain peritoneal shunt abdominal paracentesis cone, it is characterized in that: comprise that tail end is with the cone core of handle, be sleeved on the outer sleeve pipe of cone core, have on the sleeve pipe tube wall along the side channel of casing axis direction, the front end that the cone core stretches out sleeve pipe is taper, and the sleeve pipe tail end is that bending passes through a cutting ferrule sleeve pipe is fixed on handle, and isocon is inserted the abdominal cavity along sleeve pipe, cutting ferrule is fixed on sleeve pipe on handle, sleeve pipe rotation when preventing from performing the operation.

Described sleeve pipe front end tube wall chamfering, chamfer angle is identical with cone core tapered front end angle.Prevent that sleeve pipe from causing scratch.

Described sleeve pipe side channel runs through sleeve pipe, and the side channel width on sleeve pipe is less than the isocon diameter.Can be easily isocon be taken out in along side channel from isocon.

Handle is the narrow rectangle of the wide end of an end.Conveniently hold.

Compared with prior art, the beneficial effect that this utility model ventricles of the brain peritoneal shunt abdominal paracentesis cone has is: this utility model is simple in structure, easy to operate, cost is low, and the abdominal end that just can complete isocon that need not to perform the operation is inserted intraperitoneal, has solved the prior art abdominal and has inserted, wound is large, operating time is long, the post-operative recovery time is long, and easily causes the problem such as complication, greatly alleviates patient's the advantages such as misery.

Wherein: 1, handle 2, cone core 3, sleeve pipe 4, cutting ferrule.

The specific embodiment

Fig. 1 ~ 2nd, the most preferred embodiment of this utility model ventricles of the brain peritoneal shunt abdominal paracentesis cone is described further below in conjunction with 1 ~ 2 pair of this utility model of accompanying drawing.

With reference to accompanying drawing 1 ~ 2: ventricles of the brain peritoneal shunt abdominal paracentesis cone comprises that tail end is with cone core 2, sleeve pipe 3 and the cutting ferrule 4 of handle 1.The front end of cone core 2 is taper, sleeve pipe 3 is sleeved on outside cone core 2, the long 120mm of sleeve pipe 3, cone core 2 tapered front end are stretched out sleeve pipe 3, sleeve pipe 3 tail ends have one section semi-circular tube, the later half pipe of bending just in time is stuck on handle 1 sheer pole of cone core 2 afterbodys, then by cutting ferrule 4, both is fixed fixingly, and sleeve pipe 3 is movably fixed to outside cone core 2.Have along the side channel of sleeve pipe 3 axis directions on sleeve pipe 3 tube walls, side channel runs through sleeve pipe 3, and the side channel width is 2.4mm, sleeve pipe 3 front end tube wall chamferings, and chamfer angle is identical with cone core 2 tapered front end angles.

operation principle and work process are as follows: ventricles of the brain peritoneal shunt abdominal paracentesis cone slowly thrusts stomach wall, when puncture peritoneum have fall through the sense after, keep sleeve pipe 3 motionless, stir cutting ferrule 4, make cutting ferrule 4 leave semi-circular tube on sleeve pipe 3, take out cone core 2, the abdominal end of isocon is sent into intraperitoneal along sleeve pipe 3 inwalls, in operation, isocon external diameter used is 2.5mm, after the abdominal end of isocon is placed and is completed, keep isocon motionless, sleeve pipe 3 is extracted out from intraperitoneal along isocon, because isocon is flexible pipe, isocon can be taken out in the side channel from the sleeve pipe 3, sew up at last incision of abdominal wall.

The above, it is only preferred embodiment of the present utility model, be not to be this utility model to be done the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.

Claims (4)

1. a ventricles of the brain peritoneal shunt abdominal paracentesis is bored, it is characterized in that: comprise that tail end is with the cone core (2) of handle (1), be sleeved on the outer sleeve pipe (3) of cone core (2), have along the side channel of sleeve pipe (3) axis direction on sleeve pipe (3) tube wall, the front end that cone core (2) stretches out sleeve pipe (3) is taper, and sleeve pipe (3) tail end is that bending passes through a cutting ferrule (4) sleeve pipe (3) is fixed on handle (1).
