Technical field

This utility model relates to a kind of surgical medical equipment, relates in particular to a kind of art prelocalization device of shallow table lump.

Background technology

At present, development along with clinical surgery and iconography technology, the puncture guider has been applied to treatment of diseases such as breast tumor under the B ultrasonic, the patent No. is the patent of ZL03202358.8, disclose special-purpose lancet device under the ultrasonic guidance of a kind of medical mammary gland tumor aspiration biopsy and art prelocalization, formed by members such as negative pressure suction cup, inserting needle guide holder, probe draw-in groove and negative pressure straws, but the structure of this guider and complicated operation, the installation cost costliness is unfavorable for popularizing and applying in clinical.

The utility model content

Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of easy and simple to handle, accurate positioning is reliable, safety good and cost is low shallow table lump art prelocalization device is provided.

For solving the problems of the technologies described above, this utility model adopts following technical proposals.

A kind of shallow table lump art prelocalization device of the present utility model comprises the trocar and nook closing member, and nook closing member places in the trocar, an end that it is characterized in that the trocar is a trocar tip, the needle point of nook closing member and trocar tip are positioned at same end, and the needle point place of nook closing member is provided with barb, and the length of nook closing member is longer than the trocar.

Described nook closing member surface is that the direction of the past nook closing member needle body of starting point is provided with scale successively with the needle point.

The described graduated 5mm～10mm that is spaced apart.

The other end of the described trocar is provided with handle.

The barb of described nook closing member needle point is one-sided hook, also can be arranged to double hook or four hooks.

Compared with prior art, advantage of the present utility model is: under the guiding of image documentation equipments such as B ultrasonic, puncture in shallow table lump through skin by device of the present utility model, realizing art prelocalization, and can measure the subcutaneous depth of shallow table lump by the scale on the nook closing member to shallow table lump.Apparatus structure of the present utility model is simple, and is easy and simple to handle, and accurate positioning is reliable, helps the excision to focus, reduces unnecessary histologic lesion, for condition has been created in the safety operation of invisible focus.Utilize image documentation equipment channeling conducts such as B ultrasonic, device is provided with scale, and the location more accurately, intuitively.This utility model can adopt disposable material to make, safety and sanitation, and cost is low.

The specific embodiment

As Fig. 1～shown in Figure 4, this utility model comprises the trocar 1 and nook closing member 2, and nook closing member 2 places in the syringe of the trocar 1, one end of the trocar 1 is the trocar tip 6 of ramp type, the other end is provided with handle 5, and the needle point of nook closing member 2 and trocar tip 6 are positioned at same end, and the needle point place of nook closing member 2 is provided with a barb 3.The length of nook closing member 2 is longer than the trocar 1.Direction from the needle point of nook closing member 2 toward the nook closing member needle body is provided with scale 4 successively, scale 4 be spaced apart 10mm.

The barb 3 of nook closing member needle point is except that by Fig. 3, shown in Figure 4 being arranged to the one-sided hook, can also be arranged to as Fig. 5, arrow shaped bilateral hook shown in Figure 6.Also can be for as shown in Figure 7, the needle point place of nook closing member 2 is set as is the four hook-shaped of symmetrical distribution.

When this utility model uses, under the B ultrasonic location, earlier the syringe of nook closing member 2 through the trocar 1 inserted, the needle point of nook closing member 2 is hidden in trocar tip 6 inside earlier and does not expose, then the trocar 1 is thrust the arrival lump together with nook closing member 2 through each layer tissues such as skins, nook closing member 2 is pushed ahead slightly, make barb 3 penetrate lump, nook closing member 2 after being fixed in lump is extracted the trocar 1, stay nook closing member 2, can accurately find focus during operation, and can judge the degree of depth of lump, make things convenient for operation technique from the scale on the nook closing member 24.

This utility model is simple in structure, and is easy and simple to handle, and accurate positioning is reliable, helps the excision to focus, reduces unnecessary histologic lesion, for condition has been created in the safety operation of invisible focus.

This utility model adopts disposable material to make, safety and sanitation, and cost is low.
