Abstract
The invention provides a piston type bone and soft tissue tumor biopsy needle. The piston type bone and soft tissue tumor biopsy needle comprises a needle kernel (1), a thin-wall needle tube (3) and a silicone rubber sealing piece (2). The needle kernel (1) is composed of a handle cover (1-1) and a needle core (1-2) fixedly connected with the handle cover (1-1), the thin-wall needle tube (3) is composed of a handle body (3-1) and a tube sleeve (3-2), wherein the handle body and the tube sleeve are integrated, the needle core (1-2) is also a piston rod, and when the needle core (1-2) moves backwards through the sealing effect of the silicon rubber sealing piece (2), negative pressure is formed on the front section of the tube sleeve (3-2).
Description
Technical field
The present invention relates to a kind of biopsy needle, be specifically related to a kind of piston type bone and soft tissue neoplasms biopsy needle, belong to technical field of medical instruments.
Background technology
At present, biopsy needle of the prior art, its drawback is to take bone and the difficult taking-up of soft tissue neoplasms tissue in process, and one-time success rate is low, need to carry out repeatedly tumor tissues collection, and repeated localised puncture easily pollutes, totally unfavorable to patient's prognosis.
Summary of the invention
The object of the invention is in order to solve existing biopsy needle taking bone and soft tissue neoplasms tissue in process to be difficult for taking out, one-time success rate is low, need to carry out repeatedly tumor tissues collection, repeated localised puncture easily pollutes, the problem totally unfavorable to patient's prognosis, and then a kind of piston type bone and soft tissue neoplasms biopsy needle are provided.
Technical scheme of the present invention is: piston type bone and soft tissue neoplasms biopsy needle comprise pin stamen, thin-walled needle tubing, silicone rubber seal, described pin stamen forms by handle cover with the affixed nook closing member of handle cover, and thin-walled needle tubing forms by handle body with handle body all-in-one-piece pipe box processed.
The present invention compared with prior art has following effect: sleeve pipe of the present invention can pass through the needle tubing of existing bone puncture needle, utilizes nook closing member to retreat the interior negative pressure of sleeve pipe of formation, can once successfully take out bone tumor tissue, myeloid tissue and bone marrow fluid.The present invention is applicable to the bone of orthopaedics and the myeloid tissue of soft tissue neoplasms biopsy and hematology and bone marrow fluid collection.
Brief description of the drawings
Fig. 1, Fig. 2 are structural representations of the present invention.
Detailed description of the invention
In conjunction with Fig. 1, Fig. 2, present embodiment is described, the piston type bone of present embodiment and soft tissue neoplasms biopsy needle comprise pin stamen 1, thin-walled needle tubing 3, silicone rubber seal 2, described pin stamen 1 forms by handle cover 1-1 with the affixed nook closing member 1-2 of handle cover 1-1; thin-walled needle tubing 3 forms by handle body 3-1 with handle body 3-1 all-in-one-piece pipe box processed 3-2; nook closing member 1-2 is also piston rod; when the sealing function of silicone rubber seal 2 retreats nook closing member 1-2, and the leading portion of pipe box 3-2 forms negative pressure.
Using method: using method of the present invention is described in conjunction with Fig. 1, Fig. 2, penetrate cortical bone with existing bone puncture needle, extract solid interior pin, insert the needle tubing of existing bone puncture needle at the state of Fig. 1, when pipe box 3-2 enters bone inner tissue, pull back handle cover 1-1, nook closing member 1-2 displacement backward, make the leading portion of pipe box 3-2 form negative pressure, meanwhile pipe box 3-2 continues to move ahead, and bone inner tissue and bone marrow fluid just enter in pipe box 3-2, extracts pipe box 3-2, pushing handle lid 1-1 forward, the tip of nook closing member 1-2 can be released the tissue collecting, bone marrow fluid.
Claims (1)
