Detailed ways

In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

As shown in Figures 1 to 7, the utility model provides an embodiment of a medical needle holding device with scissors, wherein the medical needle holding device with scissors has a scissors-type main body, and the scissors-type main body includes a first sheet body 1, a second The two-piece body 2 and the pin shaft 6 for hingedly connecting the first piece body 1 and the second piece body 2 are bounded by the pin shaft 6. The upper part of the pin shaft is the head part of the scissor body, and the lower part of the pin shaft is the scissors. The handle part of the main body of the scissors type, a needle holding area 3 for holding the needle and a thread trimming area 4 for thread trimming are arranged on the head part of the scissors type main body, wherein the thread trimming area 4 is arranged at the between the needle holding area 3 and the pin shaft 6 of the scissors body.

As shown in FIG. 2 , the needle holding area 3 includes a needle holding structure 31 located on the first sheet body 1 and a needle holding structure 32 located on the second sheet body 2 . The needle holding structure 31 and the needle holding structure 32 are mutually Matching, the needle-holding structure can be set to a grid structure as shown in FIG. 3 , or can be set to a tooth-like structure, so that there is a certain frictional force when clamping the suture.

As shown in Figures 2 and 4, the thread cutting area 4 includes a first cutting edge 41 located on the first sheet body 1 and a second cutting edge 42 located on the second sheet body 2. The second cutting edge The edge 42 is arranged in a positive step shape, the first shearing edge 41 is arranged to match the second shearing edge 42 and is in an inverted step shape, and the first shearing edge 41 and the second shearing edge 42 form an inner shearing surface (the thick solid line shown in FIG. 4 ), at least one plane connected with the shearing surface in the first shearing edge is an inclined surface.

As shown in FIGS. 2 and 4 , the first cutting edge 41 and the second cutting edge 42 form a thread cutting area 4. Based on the stepped design of the cutting edge, the cutting surface can be hidden inside the head portion of the scissors body, It is not easy to cut the tissue when cutting the deep thread; and the overlapping part of the two cutting edges can be very small, and the cutting edge is narrow. The cutting can be completed with a small amplitude, which is in line with the clinician's habit of using conventional needle-holding forceps and medical scissors.
