Embodiment 1

[0028] Embodiment one, with reference to Figure 1-5 , a device for preventing tumor spread after bone tumor biopsy, comprising a base 1, the front end of the base 1 is provided with a plugging plunger 8, wherein, the outer side of the base 1 is evenly provided with installation grooves 2, which is convenient for passing The clamp is fixed, and the plugging plunger 8 is installed in the pinhole or tunnel to be blocked; the front end of the plugging plunger 8 is provided with an inflatable sealing component; Tube 10, expansion tube 10 coincides with the axis of plugging plunger 8 and communicates with each other, and longitudinal grooves 15 are evenly opened on the side walls around expansion tube 10; plugging plunger 8 is provided with plunger hole 8-1; The plunger channel 8-1 of the plunger 8 is filled with a high-pressure air bag 12; the push trigger mechanism on the base 1 can push the high-pressure air bag 12 into the expansion tube 10; when working, the plunger 8 will be ...

Embodiment 2

[0030] Embodiment 2, this embodiment adds the following technical features on the basis of Embodiment 1:

[0031] The front end of the expansion tube 10 is clamped with an anti-tumor capsule 11 , the anti-tumor capsule 11 is tapered and filled with anti-tumor drugs 14 .

[0032] Working principle: when working, the plugging plunger 8 is installed on the pinhole or channel left after the bone tumor biopsy, and is used to block the pinhole or channel. It acts on the front end of the plugging plunger 8 to expand and seal, greatly improving the sealing effect of the front end of the plugging plunger 8, and effectively preventing the tumor from spreading.

Abstract

The invention discloses a device for preventing tumor diffusion after bone tumor biopsy. The device comprises a base, wherein a plugging plunger is arranged at a front end of the base, an expansion-type plugging assembly is arranged at a front end of the plugging plunger, and a pushing trigger mechanism is arranged at a rear side of the base corresponding to the expansion-type plugging assembly; the expansion-type plugging assembly comprises an expansion pipe arranged at the front end of the plugging plunger, the expansion pipe is superposed with and communicated with an axis of the plugging plunger, and longitudinal grooves are uniformly formed in a peripheral side wall of the expansion pipe; a plunger hole channel is arranged in the plugging plunger; a high-pressure air bag is filled inthe plunger hole channel of the plugging plunger; and the pushing trigger mechanism on the base can push the high-pressure air bag into the expansion pipe. During working, the plugging plunger is installed on a pinhole or a hole channel left after bone tumor biopsy and used for plugging the pinhole or the hole channel, the expansion-type plugging assembly at the front end of the plugging plunger generates an expansion effect to expand and seal the front end of the plugging plunger, thus the sealing effect at the front end of the plugging plunger is greatly improved, and tumor diffusion can beeffectively prevented.

Description

technical field [0001] The invention belongs to the technical field of bone tumor detection equipment, and specifically relates to a device for preventing tumor spread after bone tumor biopsy. Background technique [0002] Bone tumors are tumors that occur in the bone or its accessory tissues. There are benign and malignant. Benign bone tumors are easy to cure and have a good prognosis. Malignant bone tumors develop rapidly, have poor prognosis and high mortality. Malignant bone tumors are divided into primary and secondary. Secondary malignant bone tumors are secondary malignant tumors that metastasize from other tissues or organs in the body to bones through the blood circulation and lymphatic system. Another type of lesion is called tumor-like lesions. The tissue of tumor-like lesions does not have the characteristics of tumor cell morphology, but its ecology and behavior are destructive to tumors, which are generally limited and easy to cure; [0003] During the biops...
