Abstract

The present invention discloses a bidirectional orbicular puncture localizer, comprising an orbicular matrix which is provided with a positioning hole or a slot which passes through a ball center. According to the characteristic that the orbicular matrix can be put or embedded inside the irregular position, the present invention can be used for positioning when the quite soft tissue and the irregular tissue are punctured. The orbicular matrix is provided with the positioning hole or slot, which is convenient for using. A needle penetrating hole or a slot can fix a puncture needle at the head, the feet and the left and right directions during the process of puncturing to avoid the directional deviation.

Description

Bidirectional spherical puncture positioner

Technical field

The present invention relates to a kind of puncture medical apparatus and instruments, particularly a kind of bidirectional spherical puncture positioner.

Background technology

Puncture is a kind of means of carrying out biopsy and treatment disease, is to arrive diseased region by percutaneous puncture to carry out pathological changes biopsy and particle implantation such as the percutaneous transthoracic needle biopsy art, is that percutaneous puncture arrival diseased region is treated.Be used for the diagnosis of disease on the one hand, treat by puncture injection medicine and deployment instrument on the other hand.In the piercing process, use puncture needle to penetrate in the pathological tissues, be used for collect specimen and set up service aisle.In the prior art, generally all be to adopt puncture needle directly to puncture, be prone to pin direction deflection in the soft tissue, the point of its puncture and direction are difficult to control, and number of operations increases, and makes the patient bear misery, reduces work efficiency.Organizing softer or tissue surface when irregular, the operator punctures according to subjective experience, and above problem is more obvious, relatively seriously influences diagnosis and therapeutic effect.

Therefore, need a kind of puncture localizer, can be in the process of puncture, can organize softer or the irregular situation of tissue surface under puncture, simultaneously that puncture needle is fixing on the cephalopodium left and right directions, avoid the direction change.

Summary of the invention

The object of the present invention is to provide a kind of bidirectional spherical puncture positioner, can be in the process of puncture, can organize softer or the irregular situation of tissue surface under puncture, puncture needle is fixing on the cephalopodium left and right directions, avoid the direction skew.

Bidirectional spherical puncture positioner of the present invention comprises spherical substrate, and locating hole or groove by the centre of sphere are set on the spherical substrate; The orientation indicating device of locating hole or groove is set on the described spherical substrate, described orientation indicating device comprises graduated disc and pointer, described spherical substrate is transparent, inside be provided with two parallel with locating hole or groove and be the plane at 90 ° of angles, two planes are arranged at the first half and the latter half of spherical substrate respectively; Two orientation indicating devices are arranged at respectively on two planes, and the pointer indication end is pointed to graduated disc downwards, and the upper end is connected with the spherical substrate hinge.

Further, described pointer is connected with the form hinge of spherical substrate with the edge of a knife.

Bidirectional spherical puncture positioner of the present invention, matrix is spherical in shape, can place or be entrenched in characteristics in the off side according to spheroid, therefore can when organizing more soft irregular tissue penetration, be used for the location, locating hole or groove are set on the spherical substrate, can puncture from both direction, easy to use, locating hole or groove can be fixed puncture needle in the process of puncture on the cephalopodium left and right directions, avoid the direction skew; Locating hole or groove orientation indicating device are set, can determine lancet puncture position and orientation intuitively, guarantee puncture accuracy; Indicating device adopts circular arc inclinometer form, and during use, the bubble of circular arc inclinometer always is positioned at peak, makes reading accurate, and simple in structure, processing ease; Graduated disc and pointer structure are saved cost; Two indicating devices are set, can judge lancet puncture position and orientation, further guarantee puncture accuracy, thereby guarantee diagnosis and therapeutic effect from vector axle and frontal axis both direction; Spherical substrate is divided into two parts, and back easy to use is cleaned, and makes the present invention to reuse, and can remove localizer before pulling out pin after the puncture, and is easy to use.

The specific embodiment

Embodiment one

Fig. 1 is the structural profile view of the embodiment of the invention one, Fig. 2 is the vertical view of Fig. 1, Fig. 3 be Fig. 1 along A to view, as shown in the figure: present embodiment comprises spherical substrate 1, penetrating pin hole 2 by the centre of sphere is set on the spherical substrate 1, be provided for the circular arc inclinometer 3 of penetrating pin hole 2 orientation indication on the spherical substrate 1, circular arc inclinometer 3 adopts bar formula level indicator principle, described circular arc inclinometer 3 shapes are corresponding with spherical substrate 1 shape, plane, circular arc inclinometer place and penetrating pin hole 2, the arcuate midway point of circular arc inclinometer 3 is corresponding with penetrating pin hole 2; Circular arc inclinometer 3 is two, is 90 ° of angles settings from vector axle and frontal axis both direction; Spherical substrate 1 transparent material is made, and circular arc inclinometer 3 is arranged at spherical substrate 1 inside, helps simplified structure.

Spherical substrate 1 is divided into two parts along penetrating pin hole 2, is respectively part I11 and part II12, and 3/4, two bar formula inclinometer 3 that part I11 accounts for spherical substrate 1 volume is arranged on the part I11.Divide body structure, help the cleaning of the penetrating pin hole 2 on the spherical substrate 1, make the present invention to reuse, can also after puncture, the present invention be removed, use more convenient.

Embodiment two

Fig. 4 is the embodiment of the invention two structural representations, Fig. 5 be Fig. 3 along B-B to cutaway view, as shown in the figure: present embodiment comprises spherical substrate 1, longitudinal register groove 2 by the centre of sphere is set on the spherical substrate 1, longitudinal register groove 2 is by the surface of spherical substrate 1, cross section is fan-shaped, two orientation indicating devices 3 that are used for longitudinal register groove 2 are set on the spherical substrate 1, orientation indicating device 3 comprises graduated disc 31 and pointer 32, spherical substrate 1 is transparent, inside is provided with two vertically and be the plane at 90 ° of angles, and two planes are arranged at the first half and the latter half of spherical substrate 1 respectively; Two orientation indicating devices 3 are arranged at respectively on two planes, and pointer 32 indication ends are pointed to graduated disc 31 downwards, and the upper end is connected with the form hinge of spherical substrate 1 with the edge of a knife; Longitudinal register groove 2 accounts for 1/4 of spherical substrate 1 volume.

Adopt graduated disc and pointer structure, can reach the purpose that guarantees puncture accuracy, can also effectively save manufacturing cost, make simple in structure.
