Description

Lung puncture biopsy needle fixer

Technical Field

The utility model relates to the field of medical instruments, in particular to a lung puncture biopsy needle fixer.

Background

The puncture needle is a medical instrument for taking biopsy and sucking cells from focus of human organ and consists of handle, needle sheath, needle core and biopsy needle. When in use, medical staff holds a handle at one end of the needle sheath to pierce the needle core into a focus of a patient, then pulls out the needle core and inserts a biopsy needle into the needle sheath, and finally repeatedly extracts focus tissues through a sampling groove on the biopsy needle to analyze the illness state of the patient.

With respect to the above-described related art, the inventors consider that there are drawbacks in that: when medical staff performs lung puncture, the needle insertion process of the puncture needle is easily influenced by thoracic cavity fluctuation caused by respiration of a patient, so that the needle insertion angle and the needle insertion depth of the puncture needle are changed, and further, difficulty is brought to sampling of lung focus.

Disclosure of Invention

The utility model aims to provide a lung puncture biopsy needle fixer for limiting a puncture needle in a lung puncture process.

In order to achieve the above purpose, the following technical scheme is adopted:

a lung puncture biopsy needle fixer comprises a fixed ring, a plurality of telescopic rods arranged on the outer side wall of the fixed ring, and an adhesive disc arranged at one end of the telescopic rods far away from the fixed ring; the fixed ring through hole is matched with the needle sheath of the puncture needle.

Preferably, the telescopic rods are hinged with the outer side wall of the fixed ring.

Preferably, the adhesive disc is hinged to the fixing ring.

Preferably, the telescopic rod is provided with a fastening bolt for restricting the telescopic rod from being telescopic.

Preferably, the telescopic rod comprises a first telescopic rod, a second telescopic rod and a third telescopic rod; the first telescopic rods, the second telescopic rods and the third telescopic rods are uniformly distributed on the outer side wall of the fixing ring.

According to the lung puncture biopsy needle fixer, the telescopic rod on the side wall of the fixing ring and the adhesive disc positioned at one end of the telescopic rod are combined, so that the fixing ring can be fixed above a focus to be punctured of a patient when the adhesive disc is adhered to the proper position on the skin surface of the patient.

When the needle sheath of the puncture needle penetrates through the fixing ring to puncture a focus of a patient, the fixing ring can limit the puncture needle, and the fixing ring is relatively fixed with the epidermis of the patient, so that the condition that the needle feeding angle deviates when the puncture needle is inserted into the needle is effectively reduced.

Meanwhile, when the handle at the end part of the puncture needle is abutted with the fixed ring, the fixed ring can limit the needle inserting depth of the puncture needle, so that the needle inserting depth of the puncture needle during needle inserting is effectively controlled.

In addition, the height of the fixing ring can be adjusted through the extension of the extension rod, so that the maximum needle inserting depth of the puncture needle can be adjusted according to the difference of the lesion distance of a patient from the epidermis.

In the description of the present specification, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.

The embodiment of the utility model discloses a lung puncture biopsy needle fixer.

Referring to fig. 1, a lung puncture biopsy needle holder comprises a fixing ring 1, and a through hole of the fixing ring 1 is matched with a needle sheath 22 of a puncture needle. Three telescopic rods are uniformly distributed on the outer side wall of the fixed ring 1, namely a first telescopic rod 11, a second telescopic rod 12 and a third telescopic rod 13, and one ends of the three telescopic rods are hinged with the outer side wall of the fixed ring 1.

Meanwhile, the first telescopic rod 11, the second telescopic rod 12 and the third telescopic rod 13 are respectively provided with a fastening bolt 14 for limiting the telescopic rods to stretch, wherein the fastening bolts 14 and the connection relation between the fastening bolts 14 and the telescopic rods are conventional technical means of those skilled in the art, and are not described herein.

The length of the telescopic rod can be fixed by tightening the fastening bolt 14; the telescopic rod can be extended and contracted by unscrewing the fastening bolt 14.

Further, the end of the three telescopic rods far away from the fixed ring 1 is hinged with an adhesive disc 15. When the surface of the adhesive disc 15 away from the telescopic rod is in contact with the human epidermis, the adhesive disc 15 can be adhered to the human epidermis.

When the three telescopic rods rotate around one end close to the fixed ring 1, the relative positions of the three pasting discs 15 can be adjusted, so that the appropriate bonding positions of the pasting discs 15 can be conveniently selected according to the focus size and focus positions of patients. Meanwhile, the adhesive disc 15 can be better attached to the epidermis of a human body by rotating the adhesive disc 15 around one end of the telescopic rod, and the fixing effect of the adhesive disc 15 is improved.

The embodiment of the utility model relates to a lung puncture biopsy needle fixer, which comprises the following implementation principles:

first, when the fixator is used, the relative positions of the three adhesive discs 15 are adjusted by rotating the telescopic rod around one end close to the fixing ring 1, and the adhesive discs 15 are tightly adhered to the proper positions of the patient epidermis by rotating the adhesive discs 15.

Subsequently, the fixing ring 1 is adjusted to an appropriate height while the three telescopic rods are simultaneously telescopic, and then the fastening bolts 14 on the respective telescopic rods are screwed so that the length of the telescopic rods is kept fixed, and at this time the fixing ring 1 is fixed above the lesion of the patient and kept relatively fixed with the epidermis of the patient.

With reference to fig. 2, the needle sheath 22 of the lung puncture needle is made to pass through the through hole of the fixing ring 1 from top to bottom, so that the fixing ring 1 limits the needle sheath 22, and the condition that the needle insertion angle of the needle core 23 is deviated due to the influence of the respiration of a patient in the needle insertion process is avoided.

With reference to fig. 3, the lung puncture needle continues to be advanced under the limit of the fixing ring 1 until the handle 21 of the lung puncture needle abuts against the fixing ring 1, at which time the fixing ring 1 further limits the needle advance of the lung puncture needle, thereby controlling the maximum needle advance depth of the lung puncture needle during needle advance.

Finally, the needle core 23 is pulled out, and a biopsy needle is placed in the needle sheath 22, and focus tissues of the patient are repeatedly extracted through the biopsy needle.

The above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
