Abstract
The invention discloses an air stopping valve for a puncturing device. The air stopping valve comprises a cup body made of an elastic material. The bottom surface of the cup body is a plane. A Y-shaped gap is formed in the center of the bottom surface. Arc-shaped grooves opposite to the three included angles of the Y-shaped gap are formed in the side wall of the cup body respectively. A Y-shaped structure is adopted in the gap of the bottom surface of the air stopping valve. When an instrument passes through the gap, the resistance is smaller compared with a traditional linear gap, the three parts of the Y-shaped gap can be quickly closed after the instrument is drawn out, and the sealing effect is better.
Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of perforator air shuttle valve.
Background technology
Disposable use microtrauma puncture device is the important apparatus in endoscope-assistant surgery, is the passage that enters fast human body, and it is also the matching used apparatuses of surgical instruments such as intracavity Endo-GIA/ultrasound knife simultaneously.The performance quality of perforator directly has influence on the fluency of operation, and air shuttle valve is as the indispensable parts of perforator, and sealing is arranged on the passage that surgical instruments passes through, operating theater instruments from middle incision by time, air shuttle valve plays sealing function.Air shuttle valve on existing market is generally in-line (see figure 1), apparatus by time in-line air shuttle valve be easily out of shape, make that resistance increases, easily gas leakage, and affect surgical effect.
Summary of the invention
The object of the invention is to overcome above-mentioned technological deficiency, a kind of good sealing effect, air shuttle valve that resistance is little are provided.
The technical scheme of technical solution problem of the present invention is: perforator air shuttle valve, comprise the inner cup portion of being made by elastomeric material, the bottom surface of this cup is plane, and these bottom surface central authorities are provided with Y-shaped seam, and the sidewall of inner cup portion is provided with three arcuate grooves that angle is relative that stitch with Y-shaped respectively.
Three finedraws of described Y-shaped seam are mutually 120 ° of angles.
The upper end of described inner cup portion has been provided with the annular flange of interconnect function.
The seam of air shuttle valve of the present invention bottom surface adopts Y-shaped structure, little compared with the resistance of in-line seam during by this gap at apparatus, and after apparatus is extracted out Y-shaped to be sewn under elastic reaction three finedraw quick-make sealing effectiveness better.

The axonometric chart of Fig. 2 air shuttle valve of the present invention;
The front view of Fig. 3 air shuttle valve of the present invention;
The upward view of Fig. 4 air shuttle valve of the present invention;
The top view of Fig. 5 air shuttle valve of the present invention.
Detailed description of the invention
As Figure 2-Figure 5, perforator air shuttle valve of the present invention, comprise the inner cup portion 2 of being made by elastomeric material, the upper end of inner cup portion 2 has been provided with the annular flange 1 of interconnect function, the bottom surface of this cup is plane, these bottom surface central authorities are provided with Y-shaped seam 3, and the sidewall of inner cup portion is provided with relative with three angles of Y-shaped seam respectively arcuate groove 4.Three finedraws as optimal way Y-shaped seam are mutually 120 ° of angles.Air shuttle valve of the present invention inserts when perforator at apparatus, because three valves that form Y-shaped seam have good compliance, relatively little to the resistance of apparatus, and valvular deformity is little more fits and have good sealing with apparatus; After apparatus is extracted out, under elastic reaction, three finedraw quick-makes, play the effect of sealing.
