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
It is the present invention relates to a kind of medical apparatus and instruments, more particularly to a kind of for tumor disperser on bone tumor biopsy rear defence
Background technology
When bone tumor biopsy being done to Patients with Bone Tumor, need to puncture bone tumor first, take biopsy or can not keep away
Next needle track or duct can be stayed with exempting from, at present, if the needle track that stays or duct do not deal with, the tumor in bone tumor
Cell will pass through needle track or duct is flowed to around puncture orifice, so as to form tumor diffusion, affect very much treatment, although having will be anti-
The method that tumour medicine is injected into town road or duct, but simply temporary closure substantially, time one are grown, one mistake of drug effect, tumor
Cell can be still diffused into around puncture orifice.
The content of the invention
The present invention is aiming at the problems referred to above, proposes a kind of for preventing tumor disperser after bone tumor biopsy, the dress
Put and can aid in Drug therapy at closing, so as to entirely prevented tumor while completely plugged puncture duct or needle track
The diffusion of cell.
For reaching above-mentioned technical purpose, present invention employs one kind for tumor disperser being prevented after bone tumor biopsy,
Including a T-shaped plugging device being made up of block head and pedestal integral type, one layer of titanium alloy self tapping on the block head, is coated with
Screw thread；A through hole is equipped with and block head bottom between at the top of the pedestal, top is threaded with the through hole with one
Word or cross recess, the closure bar that can block the through hole, the closure bar bottom is provided with a U-shaped hole, the U-shaped bottom hole portion bag
It is covered with one layer of absorbable medical film.
Preferably as the present invention, the pedestal, block head and closure bar are gathered by polymethyl methacrylate or high density
Ethylene is made after being mixed with tricalcium phosphate or hydroxyapatite or aluminium oxide bioceramic according to a certain percentage.
The present invention replaces the combination of material and titanium alloy by bone, and energy is permanent, closely block bone tumor puncture
Duct afterwards or needle track, can place cancer therapy drug in the U-shaped hole of the present invention in advance, after closure is formed, by absorbable
Medical films dissolving within a certain period of time, can make cancer therapy drug form sustained therapeutic effect in partial sealing area.

Specific embodiment
With reference to the accompanying drawings and detailed description the present invention is described in more detail.
As shown in Figure 1, it is a kind of for preventing tumor disperser after bone tumor biopsy, including one by block head 1 and pedestal 2
The T-shaped plugging device of integral type composition, is coated with one layer of titanium alloy tapping screw thread 3 on block head 1；At the top of pedestal 2 and
Be equipped with a through hole 4 between 1 bottom of block head, be threaded with through hole 4 top with cross recess 5, can block this
The closure bar 6 of through hole 4, it is actually used in, replace cross recess 5 also may be used with a word groove；A U is provided with the bottom of closure bar 6
Type hole 7, is coated with one layer of absorbable medical film 8 in the bottom in U-shaped hole 7.
In the present invention, it is preferred to pedestal 2, block head 1 and closure bar 6 by polymethyl methacrylate or high-density polyethylene
Alkene is made after being mixed with tricalcium phosphate or hydroxyapatite or aluminium oxide bioceramic according to a certain percentage.In actually used, on
State two kinds of material to configure in any combination.
In the present invention, general and puncture needle the diameter of the diameter of block head 1 is very nearly the same, and block head 1 is closed by titanium
After golden tapping screw thread 3 and puncture bone formation tightly connect, then cancer therapy drug can be put in the U-shaped hole 7 of 6 bottom of closure bar,
And blocked with absorbable medical film 8, closure bar 6 and through hole 4 are formed into threaded connection, after certain hour, absorbable medical then
Film 8 dissolves, and cancer therapy drug is flowed in the puncture duct of closing and plays lasting effect.
As the pedestal 2 in the present invention, block head 1 and closure bar 6 are by polymethyl methacrylate or high-density polyethylene
Alkene is made after being mixed with tricalcium phosphate or hydroxyapatite or aluminium oxide bioceramic according to a certain percentage, therefore, and bone-shaped
Can mutually merge with bone after pedestal 2, block head 1 and closure 6 certain hour of bar into connection, it is not necessary to which it is taken out.
Claims (2)
1. one kind prevents tumor disperser after being used for bone tumor biopsy, it is characterised in that including one by block head and pedestal one
The T-shaped plugging device of body formula composition, is coated with one layer of titanium alloy tapping screw thread on the block head；At the top of the pedestal and block
Head is equipped with a through hole between bottom, be threaded with the through hole top with a word or cross recess, can block this
The closure bar of through hole, the closure bar bottom are provided with a U-shaped hole, and the U-shaped bottom hole portion is coated with one layer of absorbable medical film.
2. one kind as claimed in claim 1 prevents tumor disperser after being used for bone tumor biopsy, it is characterised in that the base
Seat, block head and closure bar are by polymethyl methacrylate or high density polyethylene (HDPE) and tricalcium phosphate or hydroxyapatite or oxidation
Aluminum bioceramic is made after mixing according to a certain percentage.
