Problems solved by technology

[0002] When doing bone tumor biopsy for bone tumor patients, it is necessary to puncture the bone tumor first, and taking the biopsy may inevitably leave a needle or hole. At present, if the left needle or hole is not treated, the bone tumor The tumor cells inside will flow to the surrounding of the puncture port through the needle or hole, thus forming tumor spread, which greatly affects the treatment. Although there is a method of injecting anti-tumor drugs into the town or hole, it is basically only a temporary blockage. After a long time, once the effect of the drug wears off, the tumor cells will still spread around the puncture site

Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0010] Depend on figure 1 It can be seen that a device for preventing tumor spread after bone tumor biopsy includes a T-shaped sealing device composed of a sealing head 1 and a base 2, and a layer of titanium alloy self-tapping is coated on the sealing head 1. Thread 3; a through hole 4 is perforated between the top of the base 2 and the bottom of the plugging head 1, and a plug with a cross groove 5 on the top is threaded on the through hole 4 and can block the through hole 4 Rod 6, in actual use, it is also possible to replace the cross groove 5 with a straight groove; a U-shaped hole 7 is arranged at the bottom of the plugging rod 6, and a layer of absorbable medical film 8 is coated on the bottom of the U-shaped hole 7 .

[0011] In the present invention, the preferred base 2, plugging head 1 and plugging rod 6 are mixed accordi...

Abstract

The invention discloses a device for preventing tumor progression after bone tumor biopsy. The device comprises a T-shaped plugging device which is integrally formed by a plugging head and a base, wherein the plugging head is wrapped by a layer of titanium alloy self-tapping threads; a through hole is formed between the top of the base and the bottom of the plugging head; a plugging rod with a straight line or cross shaped groove in the top and for plugging the through hole is in threaded connection with the through hole; a U-shaped hole is formed in the bottom of the plugging rod; a layer of absorbable medical membrane wraps the bottom of the U-shaped hole. With the combination of a bone substitute material and a titanium alloy, a pore channel or a needle channel left after bone tumor puncture can be permanently and tightly plugged, anti-tumor medicines can be put into the U-shaped hole in advance, and once the pore channel or the needle channel is plugged, the anti-tumor medicines can be dissolved within a certain time by using the absorbable medical membrane and has the lasting treatment effect within a partial plugged area.

Description

technical field [0001] The invention relates to a medical device, in particular to a device for preventing tumor spread after bone tumor biopsy Background technique [0002] When doing bone tumor biopsy for bone tumor patients, it is necessary to puncture the bone tumor first, and taking the biopsy may inevitably leave a needle or hole. At present, if the left needle or hole is not treated, the bone tumor The tumor cells in the town will flow to the surrounding of the puncture port through the needle or hole, thereby forming tumor spread, which greatly affects the treatment. Although there is a method of injecting anti-tumor drugs into the town or hole, it is basically only a temporary blockage. After a long time, once the effect of the drug wears off, the tumor cells will still spread around the puncture site. Contents of the invention [0003] The present invention aims at the above problems, and proposes a device for preventing tumor spread after bone tumor biopsy. The...
