Embodiment 1

[0027] like figure 1 As shown, Embodiment 1 discloses an improved cutter head for wound suture removal. The improved cutter head is fishhook-shaped, and it includes an integrally connected cutter bar 1 and a curved hook 2. The curved hook 2 The pointed head of the hook is set as a blunt head 4, the outer surface of the crotch 2 is a smooth arc surface, and the inner curved surface of the crotch 2 is provided with a blade 3.

[0028] During specific use, the surgeon can manually make the crotch 2 pass through the tightly stitched coil, and then pass the blade 3 on the inner curved surface of the crotch 2 across the coil to cut off and remove the stitches. The operation is simple. At this time, due to the crotch 2 The outer surface is a smooth arc surface, which can protect the sutured wound.

[0029] like figure 1 As shown, in the first embodiment, the hook tip head of the crotch 2 is provided with a hook tip barb 5 on the side facing the inner curved surface. Such arrangeme...

Embodiment 2

[0033] like figure 2 , image 3 As shown, Embodiment 2 discloses an improved wound suture stitch removal tool, including a cutter head and a handle 6, and the rear end of the cutter head is fixedly installed in the handle 6; Improved blade for wound suture removal.

[0034] like figure 2 and image 3 As shown, in the present embodiment 2, the front end of the handle 6 is provided with a slot 6a, the tool bar 1 of the cutter head is inserted in the slot 6a, and a slot 6a is provided between the handle 6 and the tool bar 1 Locking mechanism 7. The handle 6 is connected stably with the knife bar 1 through the locking mechanism 7 .

[0035] like figure 2 and image 3 As shown, in this embodiment 2, the locking mechanism 7 includes a ejection spring 7.1, an unlock button 7.2, an unlocking spring 7.3, a locking hook 7.3, a limit spring 7.5 and a spring cap 7.6; the ejection spring 7.1 is installed In the slot 6a, one end of the ejection spring 7.1 is fixedly connected to ...

Embodiment 3

[0040] like Figure 4 As shown, embodiment 3 discloses an improved wound suture stitch removal tool, which differs from embodiment 2 in that the structure of the locking mechanism 7 is different, and the locking mechanism 7 of embodiment 3 is simpler and lower in cost. Also lower.

[0041] like Figure 4As shown, in Embodiment 3, the locking mechanism 7 includes a locking cap 8, the front end of the handle 6 is provided with a threaded joint matching the locking cap 8, and the slot 6a is opened in the threaded joint Inside: two clamping blocks 1b are symmetrically provided on the outer wall of the rear end of the knife rod 1, and two carding grooves matching the clamping blocks 9 are symmetrically provided on the inner wall of the locking cap 8 and the slot 6a. In this way, insert the block 1b of the tool bar 1 into the card slot, and then manually screw the locking cap 8 to the threaded joint, so that the tool bar 1 is fixed more stably.

Abstract

The invention relates to an improved cutter bit for removing wound suture lines and an improved stitch removing cutter. The improved cutter bit is in a fishhook shape, and comprises a cutter bar and ahook which are integrally connected, the head of the hook tip of the hook is set as a circular blunt head, the outer side face of the hook is a smooth arc surface, and the inner curved surface of thehook is provided with a cutter point. The stitch removing cutter comprises a cutter bit and a handle, wherein the rear end of the cutter bit is fixedly arranged in the handle, and the cutter bit adopts the improved cutter bit for removing the wound suture lines. According to the improved cutter bit, the head of the hook tip of the hook is set as the circular blunt head, and the outer side face ofthe hook is the smooth arc surface, thereby not damaging the skin easily; the hook and the inner curved surface of a barb of the hook tip are set as the cutter point, which can prevent a coil from slipping off and cut off the coil, and the closely stitched coil easily penetrates through the relatively small whole cutter bit, which provides convenience for cutting off the coil. According to the stitch removing cutter, the handle is arranged for installing the improved cutter bit, the operation is convenient, and one-button disassembly and replacement of the improved cutter bit can be achievedby pressing an unlocking button, and the operation is rapid and convenient.

Description

technical field [0001] The invention relates to an improved cutter head and an improved stitch removal cutter for removing wound sutures, belonging to the technical field of medical devices. Background technique [0002] In the prior art, the wounds sutured with cosmetic sutures are usually smaller, and the color of the thread is close to the skin, and the wounds are sutured relatively tightly. In the process of removing the stitches, the stitches are removed by the stitch-removing scissors. But the head end of existing thread-removing scissors is thicker, it is difficult to pass through the thread, and it is difficult to operate. In order to remove the stitches, ophthalmic scissors are sometimes needed, but the tip of the ophthalmic scissors is sharp, and the skin is easily damaged if the operation is not careful. [0003] In order to prevent the above problems, it is therefore necessary to design an improved cutter head and an improved stitch-removing knife capable of ove...
