Description
Technical field
The present invention relates to medical supplies.
Background technology
Needle holder (Needle Holder) be also needle forceps.It is mainly used for clamping the various tissues of suture needle suture.Sometimes also use
In instrumental tie.Clamped with the point of needle holder in suture needle, rear 1/3 intersection is advisable, the needle point clamped in most cases should be to
A left side, special circumstances can to the right, and suture answers overlapping 1/3, and coiling lap is also put in pin mouth.In favor of operation, if will
Pin is clipped among needle holder, then easily pin is fractureed.Often holding needle forceps method has：
1. the method for grasp：Also cry and tackle all problems at once or completely hold, i.e., hold holding needle pliering with palm.Pincers ring is close on muscle of thenar, thumb,
Middle finger, the third finger and little finger of toe are pressed respectively against in clamp handle, and rear three finger has closed up fixation, and forefinger is pressed in the anterior paraxial section of needle forceps
Place.Expanded using thumb and the activity of big fish flesh and metacarpophalangeal joints, the tooth opened on needle forceps handle ring is buckled, and unclamps tooth button and control is held
Needle pliering dehisces size to hold pin.When closing up, thumb and muscle of thenar will be captivated with remaining metacarpophalangeal part to holding.This method is stitched
The sane direction for easily changing sewing needle is closed, suture is smooth, easy to operate.
2. fingerstall method, is traditional law enforcement.It is inserted in thumb, the third finger in pincers ring, needle forceps is controlled with finger movement strength
Opening and closing, and control it to open with closing actuating range when disturbing.It is inserted in middle finger in pincers ring and holds pincers method, is stablized because remote away from fulcrum
Property it is poor, therefore for be mistake law enforcement.
3rd, metacarpophalangeal method：Thumb is inserted in pincers ring, and the first half that forefinger is pressed in pincers does supporting guide, and excess-three finger pressure pincers ring is fixed
In the palm.Thumb can opening and closing activity up and down, control the opening of needle forceps with closing up.
Needle holder is clinical common apparatus, and frequency of use is very high.But never recommend any apparatus（Even if the device
The structure of tool front end is similar to needle holder）Replacement functionally is carried out to it.Unless situation is urgent very much, straight blood-vessel forceps can be used
Same operation is carried out, but must be careful.Looper slippage or direction is caused to change admittedly because being likely to occur and clamping not strongly, and damage is held
The situation of pin device and looper.So as to injure patient tissue or patient's hand.
Head is to bend to existing needle holder when in use, limits it in clinical use.
