Technical Field

The utility model relates to the technical field of medical equipment, specifically a bone tumor biopsy taking auxiliary sleeve.

Background

Biopsy (biopsy) is also called surgical pathology examination, and is called external examination; the method is a technology for taking out pathological tissues from a patient body by cutting, clamping or puncturing and the like to perform pathological examination according to the requirements of diagnosis and treatment, is the most important part in the diagnosis and pathology, can make clear histopathological diagnosis for most of examination cases, is regarded as the final clinical diagnosis, a bone cortex or cancellous bone sample is often required to be taken when bone tumor lesions are detected, an incision is opened through a surgical operation in the process so that a device enters the body to take the sample, a sleeve is usually adopted to provide an operation channel for enlarging the incision and stripping surrounding tissues so as to position and guide to protect soft tissues at present, however, hematocele in the process still influences the operation sight, causes the wrong operation of a doctor, influences the operation, and easily causes the fallen tumor cells to enter other parts of the patient to cause regional pollution and further causes secondary damage to the patient, the pain of patients and the risk of tumor metastasis are increased, so the prior art cannot meet the use requirements of people.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a bone tumour gets biopsy auxiliary sleeve, offer to adopt the sleeve to provide the operation passageway at present usually in solving above-mentioned background art, fix a position direction protection soft tissue, however, hematocele in this process still can influence the operation sight, lead to the doctor wrong operation to appear, the influence operation is gone on, still can carry the tumour cell who drops easily and cause local pollution to other positions of patient, increase tumour diffusion transfer risk and then cause secondary damage to patient, increase patient's painful problem of expert.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a biopsy auxiliary sleeve is got to bone tumour, includes the thick pipe, the inside of thick pipe is equipped with the tubule, the equal interference fit in outer wall top of tubule has first ring, two interference fit about the outer wall of first ring respectively with the inner wall of thick pipe, the inner wall below joint of thick pipe has the silica gel sealing washer, the right side top of thick pipe is connected with violently the pipe, the outer wall rigid coupling of thick pipe has the second ring, a plurality of through-holes have been seted up to the inner wall below of tubule.

Preferably, the through holes are uniformly distributed.

Preferably, the inner diameter of the through hole is 1-3 mm.

Preferably, the left end of the transverse pipe is flush with the right side of the inner wall of the thick pipe.

Compared with the prior art, the beneficial effects of the utility model are that: this biopsy auxiliary sleeve is got to bone tumor, through the through-hole, violently the pipe, cooperation between thick pipe and the tubule, realized collecting unnecessary blood and discharge, patient's soft tissue has not only been protected, and can prevent to cause the influence because hematocele to doctor's field of vision, avoid doctor's wrong operation to appear, guarantee the smoothness of operation, through increase silica gel sealing washer between thick pipe and tubule, can prevent that blood from getting into other of patient and closing on the position, and then avoid breaking away from other positions that tumour cell entered into patient, reduce the probability that tumour diffusion shifts, avoided causing secondary damage to patient, patient's misery has been alleviateed.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: an auxiliary sleeve for taking and biopsy of bone tumor comprises a thick tube 1, a thin tube 2 is arranged inside the thick tube 1, a cavity is formed between the thick tube 1 and the thin tube 2, first rings 3 are arranged above the outer wall of the thin tube 2 in an interference fit manner, the two first rings 3 can fix the thick tube 1 and the thin tube 2, the outer walls of the two first rings 3 are respectively in an upper-lower interference fit manner with the inner wall of the thick tube 1, a silica gel sealing ring 4 is clamped below the inner wall of the thick tube 1, the silica gel sealing ring 4 improves the sealing performance of the bottoms of the thick tube 1 and the thin tube 2, a transverse tube 7 is connected above the right side of the thick tube 1, a second ring 6 is fixedly connected to the outer wall of the thick tube 1, the second ring 6 is convenient for connecting the thick tube 1 with an external binding band, ten through holes 5 are formed below the inner wall of the thin tube 2, the through holes 5 are convenient for allowing fluids such as blood and the like to enter the cavity between the thick tube, the inner diameter of the through hole 5 is 3-6 mm, and the left end of the transverse pipe 7 is flush with the right side of the inner wall of the thick pipe 1.
