Embodiment 1

[0048] see figure 1 , the device 10 for sealing bone tissue of the present invention, the device includes a sleeve 11 , a sealing plug pusher 12 and a sealing plug 13 .

[0049] The casing 11 includes a cap and a tube body 111 connected to the cap. The sealing plug pusher 12 includes a push cover 120 and a pusher body 121 coupled to one side of the push cover 120 . The length of the thruster body 121 is shorter than the length of the tubular body 111 of the sleeve 11 , and the diameter of the pusher body 121 is smaller than the diameter of the through hole of the sleeve 11 . The sealing plug propeller is made of medical stainless steel material.

[0050] The sealing plug 13 includes a plug body 131 and an annular fin 132 around the plug body 131 . The outer diameter of the annular fin 132 on the outer periphery of the plug body 131 is 1mm larger than the diameter of the through hole of the casing 11, and the sealing plug 13 is made of polyester material that can be implante...

Embodiment 2

[0053] see figure 2 , the bone tissue puncture tool 20 of the present invention, the tool includes a sleeve 21, a bone puncture needle 22, a sampling tube 23, a seal plug pusher 24 and a seal plug 25.

[0054]The sleeve 21 is a hollow tube, including a tube cover 210 and a tube body 211 on one side of the tube cover 210 . The tube cover 210 of the casing 21 is provided with an opening, and the opening forms a through hole extending along the tube body 211 to the end of the tube body 211 . A blocking area 212 is formed near the end of the tube body on the sleeve 21 , rough protrusions are arranged on the outer wall of the blocking area, and the sleeve is made of medical stainless steel. The barrier region 212 may also be an area of ​​increased tubular outer diameter of the sleeve.

[0055] The bone puncture needle 22 includes a needle cover 220 and a needle body 221 on one side of the needle cover 220 . The needle body 221 forms a tapered acupuncture portion 222 at the end a...

Embodiment 3

[0060] see image 3 , the bone hole sealing plug 33 according to another embodiment of the present invention, the sealing plug 33 is made of a self-expanding material, and the outer periphery of the sealing plug 34 is wound with multiple turns of cotton thread. The diameter of the sealing plug 33 is smaller than the tube body diameter of the casing, so the sealing plug is firstly compressed in the casing and enters the bone hole under the action of the sealing plug pusher. After the sealing plug 33 leaves the sleeve pipe, the volume of the sealing plug expands to just block the entire bone hole, and then slowly remove the cotton thread and the sleeve pipe on the periphery of the sealing plug to complete the sealing.

Abstract

The invention provides a bone hole sealing instrument, which comprises a sleeve, a sealing bolt and a sealing bolt propeller, wherein the sealing bolt propeller is used for propelling the sealing bolt in the sleeve. The invention also provides a bone tissue puncture tool, which comprises a bone puncture needle, a sampling tube and the bone hole sealing instrument, wherein the bone puncture needle passes through the sleeve. The bone hole sealing instrument has the advantage that the sealing bolt can be enabled to be pushed into a bone hole from the sleeve in a single direction and is embedded into the bone hole. The bone tissue puncture tool has the advantages that after the sampling completion, the bone hole is sealed in time through the sealing bolt before the sleeve is taken down, and in the whole operation process, interstitial fluid in the bone hole cannot be outwards permeated, so the risk of malignant tumor transfer is avoided.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an instrument for sealing a bone hole, and also relates to a tool for puncturing bone tissue including the instrument, and a method for taking bone tissue through the tool for puncturing bone tissue. Background technique [0002] Pathological examination is the most important basis for tumor diagnosis, so patients with suspected bone tumors need to undergo pathological examination to confirm the diagnosis. [0003] For patients with bone tumors, during pathological examination, it is necessary to remove small pieces of tissue or surgical resection specimens from the lesion of the patient's body to support pathological sections, observe the morphological and structural changes of cells and tissues, in order to determine the pathological properties and make a pathological diagnosis. For pathological sampling of bone tissue tumors, it is suitable for obtaining patient tissue sampl...
