Description
Technical field
This utility model relates to medical instruments field, especially a kind of bone tumor biopsy needle.
Background technology
In treatment bone tumor disease, taking biopsy samples to do pathological diagnosis is primary central aspects, domesticly generally all adopt less invasive techniques at present, sample is gathered with piercing method, when puncturing, bone wall need be penetrated, pass bone arm with biopsy needle again, extract the tumor biopsy sample in bone, because sclerotin is harder, existing puncture instrument is all not very good when puncturing, conventional bone tumor tissue biopsy needle, after the boring of bone wall, also needs puncture needle core to be replaced by tubular sampler, this puncture needle not only complex operation, and sampler to get the rate of obtaining lower.
Summary of the invention
Technical assignment of the present utility model is a kind of bone tumor biopsy needle provided for above the deficiencies in the prior art.
This utility model solves the technical scheme that its technical problem adopts: a kind of bone tumor biopsy needle, comprise trocar sheath and trocar sheath handle, also comprise puncture needle tubing and puncture needle tubing handle, micromachine is provided with in described puncture needle tubing handle, described micromachine is connected with puncture needle tubing, the sidewall on described puncture needle tubing top is fixedly connected with negative pressure joint, and the sidewall of described puncture needle tubing bottom is provided with suction inlet, and the bottom of described puncture needle tubing is coniform.
The utility model has the advantage of: 1, this utility model integrates puncture needle and extraction tube, structure is simple, easy to operate, safe and reliable, and sampling acquisition rate is high; 2, this utility model is provided with micromachine, without the need to artificially rotating puncture, being suitable for and carrying out Biopsy sampling to harder bone tumor tissue, can extensive use clinically.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of part A in Fig. 1.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described below.
As depicted in figs. 1 and 2, a kind of bone tumor biopsy needle, comprise trocar sheath 4 and trocar sheath handle 3, also comprise puncture needle tubing 5 and puncture needle tubing handle 1, in described puncture needle tubing handle 1, be provided with micromachine 6, described micromachine 6 is connected with puncture needle tubing 5, and the sidewall on described puncture needle tubing 5 top is fixedly connected with negative pressure joint 2, the sidewall of described puncture needle tubing 5 bottom is provided with suction inlet 7, and the bottom of described puncture needle tubing 5 is coniform.
Its operation principle is: during use, is pierced into by puncture needle tubing 5 in trocar sheath 4, trocar sheath handle 3 of holding with a firm grip on the other hand, to hold with a firm grip on the other hand puncture needle tubing handle 1, puncture needle is inserted tested position, opens motor 6 switch, motor 6 drives puncture needle 5 to rotate, bone wall is punctured, by means of the sense that falls through of hands, judge whether to penetrate bone wall, penetrate rear disable motor 6 switch, external negative pressure suction device is connected on the negative pressure joint 2 of puncture needle tubing 5, by bone tumor tissue aspiration out.
