Abstract
The utility model relates to a medical instrument for pleural biopsy. The utility model comprises a needle tip (1), an umbrella biopsy forceps (2), a needle body (3), an automatic switch (4), a needle core (5), and a lateral hole (6). The needle tip (1) is a hollow cone. The biopsy forceps (2) is made up of two metal jaws which have sharp edges and are depressed inward and adapted to engage with each other when closed. The needle body (3) is a hollow cylinder with tapered tip. The lateral hole (6) is received in the needle body (3) below the engagement site of the biopsy forceps (2). The automatic switch (4) is received in the needle body (3) and provided inside with the needle core (5). After the biopsy forceps (2) is opened, the included angle between two jaws is large and jaw edge is sharp, thereby facilitating to sample pleural tissues.
Description
Technical field this utility model relates to medical apparatus and instruments, specifically a kind of apparatus that is used for biopsy of pleura.
Background technology has the capable biopsy of pleura of the needs of patients of many unknown cause hydrothorax clinically to clarify a diagnosis, and the biopsy of pleura pin of prior art uses inconvenience, and the pleura of getting is less, and positive rate is not high.
The summary of the invention the purpose of this utility model is to overcome the deficiencies in the prior art and a kind of novel biopsy of pleura pin is provided.
The technical solution of the utility model is: this utility model is by needle point, the umbrella shape biopsy forceps, the needle body, automatic interrupter and nook closing member are formed, it is characterized in that: needle point is for conical, biopsy forceps by two clear-cut margins, that cave inward, two sheet metals that can be interlocked are formed when closing, the needle body is up-thin-low-thick cylinder, and automatic interrupter is arranged on the needle body.
Advantage of the present utility model: 1, novel structure, simple to operate, reliable in function is convenient to grasp.2, effectively carry out biopsy of pleura.Because area was big when the umbrella shape biopsy forceps opened, the biopsy forceps clear-cut margin is easy to effective clamp pleura.
Appended drawings is a structural representation of the present utility model.
Specific embodiment this utility model is by needle point 1, umbrella shape biopsy forceps 2, the needle body 3, automatic interrupter 4, nook closing member 5, side opening 6 are formed, all adopt metal to make, needle point 1 is the open circles taper, biopsy forceps 2 by two clear-cut margins, that cave inward, two sheet metals that can be interlocked are formed when closing, push up as umbrella.The needle body 3 is up-thin-low-thick hollow cylinder, is the cylinder of even thickness when biopsy forceps is interlocked.Have side opening 6 on the needle body 3 below biopsy forceps 2 interlocks place.Automatic interrupter 4 is arranged on the needle body 3.There is a nook closing member 5 biopsy needle inside.
During use, at first close the umbrella shape biopsy forceps, carry out thoracentesis by common program with the biopsy of pleura pin, have and break through the sense back and extract nook closing member and see that provable biopsy forceps has entered the thoracic cavity when having chest fluid to flow out, will insert by nook closing member, open biopsy forceps 2, then biopsy needle is returned and remove, close biopsy forceps 2 when having treated resistance, get pleura with pincers.At last biopsy needle is extracted.Biopsy is inspected by ready samples.
