Embodiment Construction

[0007] combine figure 1 , figure 2 Describe this embodiment, the piston-type bone and soft tissue tumor biopsy needle of this embodiment includes needle core 1, thin-walled needle tube 3, silicone rubber seal 2, and described needle core 1 is made of handle cover 1-1 and with handle cover 1- 1 is composed of fixed needle core 1-2, thin-walled needle tube 3 is composed of handle body 3-1 and sleeve 3-2 integrated with handle body 3-1, needle core 1-2 is also a piston rod, silicon When the sealing effect of the rubber seal 2 makes the needle core 1-2 retreat, the front section of the pipe sleeve 3-2 forms a negative pressure.

[0008] How to use: combine figure 1 , figure 2 Illustrate the using method of the present invention, penetrate cortical bone with existing bone puncture needle, pull out solid inner needle, in figure 1 Insert the needle tube of the existing bone puncture needle into the existing bone puncture needle. When the sleeve 3-2 enters the tissue in the bone...

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 [0001] The invention relates to a biopsy needle, in particular to a piston type bone and soft tissue tumor biopsy needle, which belongs to the technical field of medical devices. Background technique [0002] At present, the disadvantages of the biopsy needles in the prior art are that the bone and soft tissue tumor tissues are not easy to take out during the collection process, the success rate is low at one time, and multiple tumor tissue collections are required, and repeated punctures are likely to cause pollution, which is extremely unfavorable to the patient's prognosis. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing biopsy needles are not easy to take out bone and soft tissue tumor tissues during the collection process, the success rate is low at one time, multiple tumor tissue collections are required, repeated punctures are easy to cause pollution, and the prognosis of patients is ex...
