Abstract
The utility model discloses an enterocoelia end puncture needle forcerebral ventricle enterocoelia split-flow. The enterocoelia end puncture needle for the cerebral ventricle enterocoelia split-flow comprises a needle core. An outer sleeve is sleeved outside the needle core. The outer sleeve is of a C shape. One side of the outer sleeve is disconnected to form a clamping groove of a drainage tube. The width of a side hole is equal to the diameter of the drainage tube. The top end of the needle core is a cone-shaped puncture needle head. The enterocoelia end puncture needle for the cerebral ventricle enterocoelia split-flow is simple in structure, the puncture needle is provided with the clamping groove of the drainage tube, and in the process of puncturing, the outer sleeve is utilized to guide the drainage tube into the enterocoelia. The purpose that the drainage tube can still be left inside the enterocoelia by utilizing the clamping groove of the drainage tube in the side direction of the outer sleeve when the outer sleeve is taken out.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of ventricles of the brain peritoneal shunt abdominal end puncture needle.
Background technology
Ventriculoperitoneal shunt be the most frequently used in the present treatment of hydrocephalus also be effective method.Ventriculoperitoneal shunt be with cerebrospinal fluid by ventricular drainage to the abdominal cavity, need during art isocon is caused abdominal part along hypodermic tunnel by head.At this moment, need to do a stringer otch at abdominal part first, and successively cut skin, subcutaneous, abdominal muscles and peritoneum, until expose the abdominal cavity, the isocon abdominal end is inserted intraperitoneal along this otch, cerebrospinal fluid enters thus intraperitoneal and also and then by omentum majus absorbs, and then the layer-by-layer suture abdominal part is successively performed the operation and finished.
This operation needs successively each layer of open abdomen, and operation is complexity, and because of the characteristic of abdominal wall structure, the risk that causes Ventral hernia is arranged.In addition, because peritoneum cuts, internal organs adhesion, the increase of ileac risk appear behind the operation in patients.Peritoneum cuts and also can cause omentum majus adhesion, isocon abdominal end to be wrapped up and then shunt failed risk by omentum majus.Therefore, if avoid each layer of open abdomen and peritoneum, directly isocon is introduced intraperitoneal by a little puncture path, will avoid the risk of above-mentioned traditional operation.
The utility model content
The purpose of this utility model provides a kind of ventricles of the brain peritoneal shunt abdominal end puncture needle, and it is simple in structure, is designed with the isocon draw-in groove at puncture needle, simultaneously isocon is introduced intraperitoneal in puncture, avoids the risk that exists in the traditional operation.
The technical solution of the utility model is:
A kind of ventricles of the brain peritoneal shunt abdominal end puncture needle comprises nook closing member, and described nook closing member overcoat has trocar sheath, described trocar sheath is c-shaped, one side of described trocar sheath disconnects and forms the drainage tube draw-in groove, and the width of described side opening is identical with the drainage tube diameter, and described nook closing member top is conical piercing needle.
Preferably, described trocar sheath is the rustless steel sleeve pipe, and described nook closing member is the rustless steel nook closing member.
The beneficial effects of the utility model are:
This utility model is simple in structure, is designed with the drainage tube draw-in groove at puncture needle, utilizes simultaneously trocar sheath that drainage tube is introduced intraperitoneal in puncture.Still can be retained in intraperitoneal to drainage tube when utilizing the drainage tube draw-in groove of trocar sheath side to realize taking out trocar sheath.
Description of drawings
For content of the present utility model is more likely to be clearly understood, below the specific embodiment and by reference to the accompanying drawings of basis, this utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, nook closing member; 2, conical piercing needle; 3, trocar sheath; 4, side opening.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining this utility model, and be not used in restriction this utility model.
This utility model provides a kind of ventricles of the brain peritoneal shunt abdominal end puncture needle, comprises nook closing member 1, and described nook closing member 1 overcoat has trocar sheath 3, and described trocar sheath 3 is the rustless steel sleeve pipe, and described nook closing member 1 is the rustless steel nook closing member.
Described trocar sheath 3 is c-shaped, and a side of described trocar sheath 3 disconnects and forms drainage tube draw-in groove 4, and the width of described side opening 4 is identical with the drainage tube diameter, and described nook closing member 1 top is conical piercing needle 2.Conical its structure of piercing needle is conducive to puncture most, and the rotation nook closing member inserts the abdominal cavity with piercing needle during operation.It is to put drainage tube for card that trocar sheath disconnects the drainage tube draw-in groove that forms, and can realize so simultaneously isocon being introduced intraperitoneal in puncture, reduces operation risk.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use this utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from the spirit or scope of the present utility model in other embodiments realization.Therefore, this utility model will can not be limited to these embodiment shown in this article, but will accord with principle disclosed herein and features of novelty the widest consistent scope.
Claims (2)
1. ventricles of the brain peritoneal shunt abdominal end puncture needle, comprise nook closing member, it is characterized in that: described nook closing member overcoat has trocar sheath, described trocar sheath is c-shaped, one side of described trocar sheath disconnects and forms the drainage tube draw-in groove, the width of described side opening is identical with the drainage tube diameter, and described nook closing member top is conical piercing needle.
2. ventricles of the brain peritoneal shunt abdominal end puncture needle according to claim 2, it is characterized in that: described trocar sheath is the rustless steel sleeve pipe, described nook closing member is the rustless steel nook closing member.
