Description

Surgical operation suturing device for linear suturing wounds

This utility model is about being used for the stiching instrument that linear cuts sews up in the surgical operation, belonging to medical apparatus and instruments.

The linear cuts stiching instrument mainly is made up of nail supporting base, nail bin, and by the effect of ejector pin mechanism, the nail groove inflection hooked nail of the nail of the seam in the nail bin being pushed to nail supporting base closes.Existing this stiching instrument is unreliable because of the nail bin location, ejector pin mechanism is stressed when mobile, make the skew of nail bin occurrence positions easily, cause part seam nail can not correctly fall in the nail groove of nail supporting base and make this part otch fail correct the stitching, often need manual several pins of squeegeeing, thereby be difficult to guarantee to sew up quality, in addition, existing structure is also not too convenient for the replacing of disposable nail bin.

The purpose of this utility model provides the linear cuts surgical operation stiching instrument that a kind of nail bin positioning stablity does not have skew and is convenient to change.

This stiching instrument of the present utility model comprises support, nail supporting base, plastics nail bin and push rod, the two ends of nail bin and nail supporting base link to each other with locating shaft with guide rod respectively, nail bin is distributed with several the nail holes that can adorn ㄇ shape seam nail, and nail supporting base has with the nail hole follows closely groove one to one; The both sides of nail bin are by two block pressur plate clampings, and both are chimeric mutually with the groove and the raised line of lateral direction penetrating respectively, and the lower end of locating shaft rocks its stable nothing by the reed clamping that is fixed on the support support arm; The rod guidance groove of the lower end of guide rod and nail bin end is halved together, and notch has a pair of inside projection, in order to avoid guide rod skids off outside the groove.

This stiching instrument is because the employing technique scheme is further reinforced the middle part of nail bin, and two ends are stable, thereby the location is correct, can guarantee the myometrial suture quality, and nail bin can laterally be taken out, insert replacing and easy for installation.

Be description of drawings of the present utility model below.
