Abstract
The invention discloses a puncturing rod comprising a holding part and a straight rod part which are mutually fixed. A front end of the straight rod part is a conical puncturing end part; the periphery of the conical puncturing end part is symmetrically provided with a wedged wing; the edge of the wedged wing is a truncated edge; and the left part and the right part of the wedged wing are symmetrical, and are connected to be arranged on the conical puncturing end part. The invention has the advantages of quickly puncturing and reducing the injury to patients as much as possible, and has favorable promotion value.
Description
Technical field
The present invention relates to a kind of perforator, relate in particular to a kind of puncturing lever of perforator.
Background technology
Perforator is a kind ofly to pierce through stomach wall and for other operating theater instruments provide the operating theater instruments that enters the body cavity passage, belong to a kind of Minimally Invasive Surgery apparatus.
Perforator generally includes as the sleeve assembly of other operating theater instruments admission passages and the puncturing lever in the described sleeve assembly.For transdermal, earlier cut epiderm skin, then puncturing lever transdermal and enter body cavity with scalpel.Exert pressure by the near-end to described puncturing lever, skin is passed at the tip that promotes described puncturing lever, enters body cavity up to it.Perforator enters body cavity, extracts puncturing lever out, and sleeve assembly just can be used as the instrument channel of carrying out endo-surgical and splanchnoscopy operation.
At present,, puncture simultaneously, cut off tissue fibers because the end of puncturing lever is a sharp knife, bigger to patient's damage.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of quick puncture, again the patient is damaged little puncturing lever.
Purpose of the present invention will be achieved by the following technical programs:
A kind of puncturing lever, comprise: grip part that interfixes and straight-bar portion, the front end of described straight-bar portion is conical puncture end, be arranged with a slice wedge shape wing on the periphery of described puncture end, described wedge shape wing edge is a root face, the described wedge shape wing is the left-right symmetric shape, and continuous providing on described conical puncture end.
Beneficial effect of the present invention is mainly reflected in: both can puncture fast, and also reduce the damage to the patient as much as possible, and have excellent popularization and be worth.
Description of drawings
Fig. 1: the front view of puncturing lever of the present invention.
Fig. 2: the left view of puncturing lever of the present invention.
Wherein:
1 grip part, 2 straight-bar portions, 3 puncture ends
The 4 wedge shape wings
The specific embodiment
Shown in Fig. 1-2, the present invention has disclosed a kind of puncturing lever, comprise: grip part 1 that interfixes and straight-bar portion 2, the front end of described straight-bar portion 2 is conical puncture end 3, be arranged with a slice wedge shape wing 4 on the periphery of described puncture end 3, described wedge shape wing edge is a root face, and the described wedge shape wing is the left-right symmetric shape, and continuous providing on described conical puncture end.Like this, when the doctor in puncture time, root face under pressure, the effect of existing puncture, do not cut off tissue fibers again, in the time of puncture, the wedge shape that the swings wing, can separate tissue, so both satisfy the demand of puncture fast, also reduce damage as much as possible the patient.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within protection scope of the present invention.
