In order to accurately position the cutting size of the foreskin, the circumcision stitching instrument capable of accurately positioning the cutting size of the foreskin further comprises: glans penis positioning device 7. The middle part of the glans penis cover 1 is provided with a positioning cavity 13, so that the glans penis positioning device 7 can be adjustably connected inside the positioning cavity 13, the relative position of the glans penis positioning device 7 and the inner wall of the glans penis cover 1 is adjusted according to the size of the foreskin to be cut by a patient, the size of the glans penis entering the glans penis cover 1 is further determined, and the technical effect of accurately positioning the foreskin cutting size is achieved.

In order to change the position of the circumcision and the suture, the circumcision suture device capable of accurately positioning the circumcision size further comprises: and an adjusting device 9. Make adjusting device 9 and 1 afterbody adjustable connection of glans penis, adjusting device 9 is connected with nail storehouse cover 2, and when using, in order to adapt to the not unidimensional requirement of patient's glans penis, can control the extension distance of glans penis cover 1 through adjusting device 9, convenient foreskin to the patient cuts.

Since the glans penis positioning device 7 is adjustably connected inside the positioning cavity 13, the relative position of the glans penis positioning device 7 and the glans penis cover 1 can be changed. In order to adjust the glans penis positioning device 7 by using the adjusting device 9, the glans penis positioning device 7 is adjustably connected with the adjusting device 9, and the glans penis positioning device 7 and the glans penis cover 1 can be relatively stretched. And then realized patient's glans penis and stretched into the regulation of distance, improved the precision to patient's foreskin cutting.

In order to enable the glans penis positioning device 7 and the glans penis cover 1 to be relatively telescopic, the length of the distance of the glans penis extending into the glans penis cover 1 is changed to be adjusted. The glans penis positioning device 7 comprises: a positioning head 71 and an adjustment lever 72. With fixed connection between location head 71 and the regulation pole 72, adjust the pole 72 and stretch into adjusting device 9 adjustable connection, reciprocate in location chamber 13 through control regulation pole 72 inside, can change the relative distance between location head 71 and the glans penis cover 1, when using glans penis cover 1 to fix the glans penis, can reach the effect of accurate location foreskin cutting size.

Preferably, a protective layer 73 is bonded in the inner cavity of the positioning head 71, and the material of the protective layer 73 is a flexible material capable of being sterilized, so that the comfort of a patient is improved.

In order to adjust the extending distance of the balanus cover 1, and the extending distance of the balanus positioning device 7 can be adjusted. The adjusting device 9 comprises: an adjusting body 91 and an elastic tailstock 92. The center of the adjusting body 91 is provided with an adjusting hole, a screw thread is arranged in the adjusting hole, and the tail of the glans penis cover 1 is provided with a screw structure, so that the screw structure is matched with the screw thread, and the glans penis cover 1 is adjusted through the adjusting device 9. When the adjusting device 9 is used for adjusting the extending distance of the balanus cover 1, the adjusting device 9 is rotated, and the stretching effect of the balanus cover 1 is controlled by the screw rod and the thread structure between the adjusting device 9 and the tail of the balanus cover 1.

Furthermore, a tail seat cavity is formed in the tail of the adjusting hole, the diameter of the tail seat cavity is larger than that of the adjusting hole, and the elastic tail seat 92 is fixedly connected inside the tail seat cavity, so that the elastic tail seat 92 elastically compresses the tail end of the tortoise head cover 1. Use adjusting device 9 control tortoise head cover 1 to reach the foreskin cutting position, because tortoise head cover 1 is lead screw, threaded connection with adjusting device 9's connected mode, consequently, can make when the fixed glans penis of tortoise head cover 1 can take place to rock between tortoise head cover 1 and the adjusting device 9, lead to foreskin cutting position to change, cause serious damage to the patient. The elastic tail seat 92 is used for elastically compressing the tail end of the balanus cover 1, the technical problem that the position of the balanus can be changed due to the fact that the balanus is fixed by pressure after the balanus cover 1 reaches the position of the foreskin cutting is solved, and the technical effect of improving the feeding precision of the balanus cover 1 is achieved while the safety of the cutting stitching instrument is improved.

Further, in order to ensure the stroke distance of the elastic tail seat 92 and the compression and fixation of the tail part of the tortoise head cover 1.
