Abstract
The utility model relates to a puncturing device capable of sampling, which is provided with a needle cylinder push rod. One end of the push rod is connected with a handle, and the other end of the push rod is connected with a cutter, wherein the cutter consists of a blade and a tool bit, and a barb-shaped open slot is arranged on one side of he tool bit. When the device is normally used in clinic, the sampled biopsy tissue enters into the open slot along with the tool bit entering a sampling part; and when the push rod is pulled and retracted in the needle cylinder, the biopsy tissue in the open slot can be completely reserved in the needle cylinder.
Description
Technical field
This utility model relates to a kind of puncture needle that is used for clinical medicine, especially a kind of sting device of taking a sample.
Background technology
For making a definite diagnosis focus situation and pathological analysis, often use the pricking device of syringe-type to get biopsy on the clinical medicine.Generally, for commonly in the holder of a syringe, being provided with the holder push rod in this kind equipment prior art, an end of push rod connects a pushing hands, and the other end of push rod connects a puncture blade.When concrete operation, the hand-held holder of operator is aimed at lesions position, promotes pushing hands push rod is pushed out of outside the holder along the holder axial direction, causes the puncture blade to intert or cutting lesions position live body, accomplishes the biopsy sampling action.With this utensil, with this method is to realize drawing the purpose of biological tissue fully, but actually effect how, as if especially the wound area of focus sample point is how, how person under inspection's pain not to be the problem that the operator is concerned about; Its technological innovation does not more have the breakthrough of this technology of since clinical traumatology, having used till today.
Summary of the invention
The purpose of this utility model provides a kind of sting device of taking a sample, and this device can solve the defective in the design of conventional needle cartridge type pricking device, through the improvement to the puncture cutter, makes sting device have disposable accurate sampling, characteristics that wound surface is little.
For this reason; The technical scheme that this utility model solves said problem is: a kind of sting device of taking a sample has the syringe pushing ram, at handle of end connection of described pushing ram; The other end of pushing ram connects a cutter; Wherein, said cutter is made up of blade, cutter head, is provided with barb-like slot in a side of said cutter head.
Preferably, the slot that is opened in said cutter head one side is concordant with cutter head avris line, and the groove of slot extends along the knife edge direction of cutter head.
Preferably, said syringe pushing ram and cutter are respectively the discrete workpiece that has bindiny mechanism.
Preferably, the workpiece of said bindiny mechanism is respectively spin slot, revolves head, or inserting groove, connection-peg.
Compared with the prior art, the present utility model has the positive effect is that the needle-like puncture device without changing the overall structure of the premise is connected only with the pusher tool to improve, improve as the original head has an inverted Exclusion hook blade slot.When clinical this device of normal use, its advantage displays immediately: the biopsy of being obtained when getting into sampling point along with cutter head gets in the slot immediately, and when the pulling push rod bounced back in syringe, what the biopsy in the slot can be complete was retained in the syringe.
Description of drawings
Fig. 1 is the perforator of prior art, and cutter head among the figure and push rod cannot discretely be provided with, and are an integral body;
Fig. 2 is the perforator of prior art, and cutter head among the figure and push rod respectively can discretely be provided with naturally, but can be connected as a single entity;
Fig. 3 is the perforator of this utility model, and the structural relation of cutter head and push rod can be designed to discrete respectively or both are affixed for holistic among the figure.
Among the figure:
The 1-syringe,
The 2-pushing ram,
The 3-handle,
The 4-cutter, the 41-blade, the 42-cutter head, the barb-like slot of 421-, the 422-groove,
Bindiny mechanism between 5-pushing ram and the cutter and workpiece.
The specific embodiment
Referring to accompanying drawing 3 and comparative drawings figs 1,2, following examples have embodied a kind of sting device of taking a sample that this utility model relates to.This device has syringe 1, pushing ram 2, connects a handle 3 at an end of pushing ram 2, and the other end of pushing ram 2 connects a cutter 4, and wherein, said cutter is made up of blade 41, cutter head 42, is provided with barb-like slot 421 in a side of said cutter head 42.
For the point of contact of cutter accurately puts in place, the slot 421 that is opened in said cutter head one side should be concordant with cutter head 42 avris lines, and the groove 422 of slot extends along the knife edge direction of cutter head; So design can guarantee that patient's the stability degree of controlling of holding a sword in one's hand is good, and the biopsy of being got can all draw in barb-like slot 421.
When the design cutter, should fully take into account the principle of a people one tool and the optimization problem of workpiece material and cost.The syringe pushing ram 2 and the cutter 4 of the sting device that this utility model relates to can be designed to respectively carry the workpiece of bindiny mechanism respectively; As required; These bindiny mechanisms can be designed to the revolve head of the spin slot of pushing ram to cutter respectively, or the inserting groove of pushing ram is to the connection-peg of cutter.The material of pushing ram and cutter can be selected in the composite of metal, pottery, plastics or these materials.
Claims (4)
1. the sting device that can take a sample has the syringe pushing ram, it is characterized in that; One end of described pushing ram connects a handle, and the other end of pushing ram connects a cutter, wherein; Said cutter is made up of blade, cutter head, is provided with barb-like slot in a side of said cutter head.
2. sting device of taking a sample according to claim 1 is characterized in that, the slot that is opened in said cutter head one side is concordant with cutter head avris line, and the groove of slot extends along the knife edge direction of cutter head.
