Abstract
The utility model discloses a tumor positioning needle, which comprises a hollow pipe puncture needle and a positioning needle arranged in the needle pipe of the hollow pipe puncture needle, wherein the positioning needle is capable of freely rotating along the axial direction of the hollow pipe puncture needle; the positioning needle is longer than the hollow pipe puncture needle; the positioning needle is made of a hydroxyapatite material; the positioning needle is made of the hydroxyapatite material instead of a metal material. As a rejection reaction is not generated on a human body by hydroxyapatite, and the hydroxyapatite has required hardness and toughness, the basic requirements on the tumor positioning needle can be met. Simultaneously, as the tumor positioning needle is not made of the metal material, the tumor positioning needle is not limited by a nuclear magnetic resonance checkup; a preoperative nuclear magnetic resonance checkup can be carried out after puncture positioning is finished, thereby being beneficial to a clinician judging the condition of a patient. The best operation mode is selected.
Description
Technical field
This utility model relates to a kind of medical apparatus, particularly a kind of positioning needle that is used for before the lump art such as female mammary gland.
Background technology
Breast carcinoma is one of female patient most common tumor, and little tumor is difficult to touch in operation, in order to excise small lesion accurately, needs before the operation the lump location that makes marks.Clinical employing be that positioning needle is made of hollow pipe puncture needle and elongated seal wire positioning needle, the cutting tip of positioning needle is provided with barb, before the puncture, earlier the needle tip with the hollow pipe puncture needle punctures to the lump place, again with positioning needle by drawing in the hollow pipe puncture needle, the needle tip of positioning needle both is punctured to allocation after, extract the hollow pipe puncture needle, positioning needle was stayed and was needed to finish the location in the localized tissue this moment, was convenient to accurately to find lump in the operation and with its excision.The positioning needle of available technology adopting is common metal seal wire or metal needle.Chemotherapy before patient with breast cancer's process art, in the time of need protecting breast conserving surgery, should carry out nuclear magnetic resonance check before the art as requested, and if lump in breast adopts the positioning needle of metal material, then, can not carry out this Xiang Shuqian and check for carrying out the contraindication of nuclear magnetic resonance check.
At above-mentioned deficiency, need work out a kind of lump positioning needle, not only simple in structure, easy to operate, accurate positioning, but also the influence of nuclear magnetic resonance check before avoiding adopting metal material as positioning needle unable to walk art.
The utility model content
In view of this, the purpose of this utility model provides a kind of lump positioning needle, not only simple in structure, easy to operate, accurate positioning, and be not subjected to the restriction of nuclear magnetic resonance check, can after the puncture location, carry out art before nuclear magnetic resonance check, be beneficial to the clinician and judge conditions of patients, select best modus operandi.
The purpose of this utility model is achieved through the following technical solutions: a kind of lump positioning needle, comprise the hollow pipe puncture needle and be built in the interior positioning needle of hollow pipe puncture needle tubing, positioning needle can axially moving freely along the hollow pipe puncture needle, the length of positioning needle is greater than the length of hollow pipe puncture needle, and positioning needle is made by hydroxyapatite material.
Further, the needle point place of described positioning needle is provided with barb;
Further, described positioning needle is provided with scale;
Further, described hollow pipe puncture needle is provided with handle away from an end of needle point.
The beneficial effects of the utility model: lump positioning needle of the present utility model is by hydroxyapatite substituted metal material, because hydroxyapatite and human body do not have rejection, and has hardness and the toughness that needs, and can reach the basic demand to the tumor-localizing pin; Simultaneously,, be not subjected to the restriction of nuclear magnetic resonance check because it is not the metal quality, can after the puncture location, carry out art before nuclear magnetic resonance check, be beneficial to the clinician and judge conditions of patients, select best modus operandi.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further described:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Fig. 1 is structural representation of the present utility model.As shown in the figure: a kind of lump positioning needle of the present utility model, comprise hollow pipe puncture needle 1 and be built in the interior positioning needle 2 of hollow pipe puncture needle tubing, positioning needle 2 can axially moving freely along hollow pipe puncture needle 1, the length of positioning needle 2 is greater than the length of hollow pipe puncture needle 1, and positioning needle 2 is made by hydroxyapatite material.During use, now positioning needle is hidden in the hollow pipe puncture needle, under the assist location of image documentation equipments such as B ultrasonic, the hollow pipe puncture needle is together arrived lump together with positioning needle behind each layer tissue such as skin, continue the forward impelling positioning needle then, insert it into lump, extract the hollow pipe puncture needle afterwards gently, positioning needle is stayed in the lump, finished the location.Lump positioning needle of the present utility model is by hydroxyapatite substituted metal material, because hydroxyapatite and human body do not have rejection, and has hardness and the toughness that needs, and can reach the basic demand to the tumor-localizing pin; Simultaneously,, be not subjected to the restriction of nuclear magnetic resonance check because it is not the metal quality, can after the puncture location, carry out art before nuclear magnetic resonance check, be beneficial to the clinician and judge conditions of patients, select best modus operandi.
As the further improvement to the foregoing description, the needle point place of described positioning needle 2 is provided with barb 3.Rollback and displacement that barb prevents positioning needle are set, and locating effect is better accurately.
As the further improvement to the foregoing description, described positioning needle 2 is provided with scale 4.Scale is set makes things convenient for the doctor to grasp the degree of depth that positioning needle enters tissue, the auxiliary particular location of accurately judging lump is convenient to operation.
As the further improvement to the foregoing description, described hollow pipe puncture needle 1 is provided with handle 5 away from an end of needle point 6.Handle is set conveniently controls, operation precisely.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although this utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
