Medical Suturing Device

Abstract

The present invention provides a medical suturing device structured with a retrieval puncturing needle formed with through-hole; a retrieval member able to be inserted through through-hole; an insertion puncture needle formed with through-hole; a hollow tube that can be inserted through insertion through-hole, and the distal tip of which is formed into a deformable bent portion; and a suture that can be inserted through the inside of hollow tube. The retrieval member is structured with an annular engagement member that can be deformed into a straight shape, a rod member that is connected to annular engagement member, and a grip that is provided with a mark. The mark is furnished on hollow tube, such that when retrieval puncturing needle and insertion puncture needle are in a condition where mark and mark are facing each other, the upper supporter and lower supporter can be detachably attached.

1 . A medical suturing device, comprising: 
 a retrieval puncturing needle having a retrieval through-hole extending from a proximal end to a distal tip;    a retrieval member that can be inserted through said retrieval through-hole of said retrieval puncturing needle, having an annular engagement member which is elastically deformable into a straight shape and a rod member that is connected to said annular engagement member;    an insertion puncture needle having a through-hole extending from a proximal end to a distal tip, the insertion puncture needle being disposed substantially parallel to said retrieval puncturing needle, maintaining a predetermined interval therebetween;    a hollow tube that can be inserted within the through-hole of said insertion puncture needle, comprising a distal tip portion having an arc shaped region elastically deformable into a straight shape; and    a suture that can be inserted into the aforementioned hollow tube.    
   
   
       2 . The medical suturing device according to  claim 1 , comprising a position indicator arranged such that when said retrieval member is deployed with its linearly extended annular engagement member side from the proximal end portion of the retrieval through-hole of the aforementioned retrieval puncturing needle, an annular shape formed when the aforementioned annular engagement member projects outwardly from the distal tip aperture of said retrieval puncturing needle which annular shape faces toward said insertion puncture needle.  
   
   
       3 . The medical suturing device according to  claim 1 , comprising a position indicator arranged such that when said hollow tube is inserted into the proximal end of the through-hole of said insertion puncture needle, and the distal tip portion projects outward from the distal tip aperture of said insertion puncture needle, the distal tip portion of said hollow tube bends to extend toward the distal tip side of said retrieval puncturing needle.  
   
   
       4 . The medical suturing device according to  claim 1 , wherein said retrieval puncturing needle and said insertion puncture needle are disposed in a substantially parallel fashion by their freely removable attachment to a support device.
