Abstract
The utility model relates to a multi-function trocar puncturing needle, which comprises an outer jacket tube and a needle core. The upper part of the needle core is provided with a groove. The outer jacket tube is provided with a hole which is corresponding to the groove on the needle core. The needle core forms a slide fit with the outer jacket tube. The rim of the groove is a thin edge, and the outer jacket tube is a thin wall tube. The top of the needle core is a needle tip, and the lower end is a turn knob. The lower part of the outer jacket tube is a needle holder. The cutting sampling of living tissue and the needle suction can be carried out after the puncture is in place. The utility model can assist a placing tube to do radiotherapy with close range; the utility model can also carry out puncture discharging liquid therapy of hydrothorax and ascites through the outer jacket tube; the utility model can inject chemotherapy drugs, hemostat, immunotherapy dosage, etc. through the outer jacket tube. The utility model has multi-function with one needle.
Description
This utility model relates to medical apparatus and instruments, particularly biopsy sampling sleeve pipe puncture needle.
Clinical biopsy drive pipe puncture needle commonly used, by trocar sheath, the band needle point nook closing member constitute, nook closing member and trocar sheath are slidingly matched, nook closing member has fixed stroke range.During sampling needle point is thrust tissue, the push-and-pull nook closing member utilizes the gap of needle point and trocar sheath to obtain biopsy.Its shortcoming is push-and-pull back and forth, and the depth is irregular, is unfavorable for spot sampling, gets less than biopsy sometimes.Though and nook closing member and trocar sheath be that being slidingly matched of certain stroke arranged, nook closing member can not be extracted out, so can't utilize trocar sheath to carry out tissue space implantation brachytherapy and injection.
The purpose of this utility model is to provide a kind of both can obtain living tissue accurately, easily, can assist to plant the sleeve pipe puncture needle of pipe radiotherapy, injection again.
Technical solution of the present utility model is: multi-functional sleeve pipe puncture needle, comprise trocar sheath, nook closing member, and nook closing member top has groove, has on the trocar sheath and the corresponding hole of groove on the nook closing member, and nook closing member and trocar sheath are slidingly matched; The groove edge is thin sword, and trocar sheath is a light-wall pipe; The nook closing member top is a needle point, and the lower end is a knob, and the trocar sheath bottom is a needle stand.
According to technique scheme, under the X line three-dimensional location of biopsy or B ultrasonic are located sterile working under the local anesthesia down.The rotation nook closing member makes the groove and the dislocation of the hole on the trocar sheath (being closed pockets) on its top earlier.After puncture put in place, this moment, living tissue was inserted on the top of the needle point of nook closing member and trocar sheath, and hand-held knob rotation makes the groove on the nook closing member corresponding with the hole on the trocar sheath, and living tissue enters in the groove of hole on the trocar sheath and nook closing member under self pressure effect.Rotate nook closing member again, groove edge on the nook closing member and overcoat pore edge produce shears, and living tissue is cut and stayed in the groove, hold knob and extract nook closing member, can obtain the biopsy sample.The living tissue cutting that has gets nowhere in the time of maybe can't cutting, and nook closing member can be extracted out after puncture puts in place, and the needle stand of trocar sheath bottom is connected suction with needle tubing, can carry out cytolgical examination.As being diagnosed as malignant tumor, when needing selectivity to carry out tissue space implantation radiotherapy, after putting in place, puncture needle extracts nook closing member, and insert disinfectant macromolecule treatment pipe and carry out brachytherapy.As repeatedly radiotherapy of need, then extract trocar sheath, keep macromolecule treatment pipe and get final product.When carrying out the ascites pleural fluid tap, extract nook closing member, trocar sheath connects transfusion device and gets final product tapping, connects the syringe injection in case of necessity.
Accompanying drawing 1 is looked sketch map for this utility model master;
Accompanying drawing 2 is that the A-A of Fig. 1 is to cross-sectional schematic.
In conjunction with the accompanying drawings, embodiment of the present utility model is described.Multi-functional sleeve pipe puncture needle comprises trocar sheath, nook closing member, and nook closing member 7 tops have the hole 3 corresponding with groove 1 on groove 1, the trocar sheath 4, nook closing member 7 be slidingly matched with trocar sheath 4 (both can pull and push, rotatable again, nook closing member 7 outer walls and the applying of trocar sheath 4 inwalls); Groove 1 edge is thin sword, and trocar sheath 4 is a light-wall pipe; Nook closing member 7 tops are needle point 2, and the lower end is a knob 6; Trocar sheath 4 bottoms are needle stand 5, and needle stand 5 adopts plastic material, and nook closing member 7, trocar sheath 4 adopt stainless steel material.
