[0037] The technical solution of the present application is described in detail below with reference to the accompanying drawings and specific embodiments, wherein the same components are denoted by the same reference numerals.

[0038] See also Figures 1 to 10 The present application discloses a press-trigger type foreskin eversion circumcision suture device, comprising a circumcision suture unit 10, which comprises a circumcision housing 100, a fixing cover 101, a nail pushing cover tube 102, a limiting tube sleeve 103, an excitation sleeve 104, a firing handle 109, a return spring 105, and a central shaft 106;

[0039] like Figures 2 to 4 As shown, the annular shell 100, the fixed cover 101 and the nail push cover tube 102 are all bell-shaped. The rear end of the annular shell 100 is provided with a connecting tube 1001, and the fixed cover 101 is fixedly sleeved in the annular shell 100; the outer peripheral surface of the front end of the fixed cover 101 is fixed with a convex ring 1011, and the front end surface of the convex ring 1011 is evenly distributed with a plurality of needle holes 1013 for placing suture nails 1012 on the circumferential direction, and a nail push cover tube 102 is provided between the fixed cover 101 and the annular shell 100. The shield tube 102 and the fixed shield 101 are matched in an axially movable and circumferentially locked manner. The front end surface of the nail push shield tube 102 has a push strip 1021 that slides in cooperation with the needle hole 1013 and can push out the suture staple 1012 in the needle hole 1013. The outer peripheral wall of the nail push shield tube 102 is fixedly sleeved with an annular cutter 1022. The nail push shield tube 102 slides to drive the annular cutter 1022 and the suture staple 1012 to cut the foreskin at the same time.

[0040] like Figure 7As shown, the front end of the limiting sleeve 103 is fixedly clamped on the inner side of the connecting tube 1001, and a push groove 1031 is axially opened on the outer wall of the rear end surface of the limiting sleeve 103;

[0041] like Figure 2 and Figure 3 As shown, the front end of the central axis 106 moves through the limiting sleeve 103 and slides with the rear end of the fixed cover 101; the trigger sleeve 104 is slidably clamped between the central axis 106 and the limiting sleeve 103, and the outer wall of the trigger sleeve 104 has a triggering portion 1041 that slides with the push groove 1031. The body of the nail push cover tube 102 is provided with a return spring 105 located between the front inner side of the limiting sleeve 103 and the front end of the trigger sleeve 104. The front end of the firing handle 109 is hinged to the ring cutting The outer wall of the shell 100, the front part of the firing handle 109 and the excitation part 1041 are movably connected through the first hinge rod 110. Pressing the firing handle 109 can drive the excitation sleeve 104 to move forward to push the nail push cover tube 102 forward to push out the suture nail 1012 in the needle hole 1013, and at the same time drive the annular cutter 1022 to move forward. After releasing the firing handle 109, the reset spring 105 resets and drives the nail push cover tube 102 and the excitation sleeve 104 to move backward, and resets the firing handle 109.

[0042] Based on the above-mentioned circumcision suture part 10, since the fixed cover 101, the circumcision shell 100 and the limiting tube sleeve 103 are fixedly connected, when the foreskin is cut, the central axis 106 is in a fixed state, and the firing handle 109 is pressed downward. The firing handle 109 rotates to drive the excitation sleeve 104 to move forward axially along the central axis 106. During the forward movement of the excitation sleeve 104, the nail push cover tube 102 is driven to move forward, and the reset spring 105 is compressed at the same time. During the forward movement of the nail push cover tube 102, the push strip 1021 on the front end face of the nail push cover tube 102 pushes out the suture nail 1012 in the needle hole 1013, and at the same time drives the annular cutter 1022 to cut the foreskin. When the firing handle 109 is released, the reset spring 105 resets and drives the nail push cover tube 102 and the excitation sleeve 104 to move backward, and resets the firing handle 109.

[0043] The circumcision and suturing part 10 of the present application can balance the force on the nail pushing cover tube 102 because the excitation sleeve 104 directly drives the nail pushing cover tube 102 to move forward. At the same time, the circumcision shell 100 and the fixed cover 101 restrict each other so that the nail pushing cover tube 102 can move horizontally accurately, thereby achieving better cutting and suturing effects.

[0044] In an optional embodiment of the present application, a glans cover 112 made of silicone material is installed in the fixing cover 101, and the glans cover 112 can protect the glans.

[0045] In an optional embodiment of the present application, three mother parts 1002 are spaced apart in the annular shell 100, and a sub-part 1015 is axially provided on the outer wall of the fixed cover 101, which is fixedly plugged into 1002 one by one. The annular shell 100 and the fixed cover 101 are fixedly connected by plugging the mother part 1002 and the sub-part 1015. The structures of the mother part 1002 and the sub-part 1015 are common structures in the prior art and will not be repeated here.

[0046] like Figure 6 and Figure 9 As shown, the central axis 106 is provided with ridges 1061 extending axially along the nail push cover tube 102 at circumferential intervals on the outer wall of the portion where it cooperates with the nail push cover tube 102, and the nail push cover tube 102 is provided with a sliding groove 1023 which is axially slidably matched with the ridges 1061 on the inner wall where it cooperates with the central axis 106. The ridges 1061 cooperate with the sliding groove 1023 so that the nail push cover tube 102 and the central axis 106 can cooperate in an axially slidable and circumferentially locked manner, so that the central axis 106 and the nail push cover tube 102 will not interfere with each other when they move relative to each other.

[0047] like Figure 3 and Figure 4 As shown, a needle spacer sleeve 1014 is fixedly provided on the front end surface of the convex ring 1011. Specifically, a plurality of blind holes 1016 are spaced circumferentially on the front end surface of the convex ring 1011. The needle spacer sleeve 1014 is made of silicone. The needle spacer sleeve 1014 is provided with a clamping column that matches the blind hole 1016 one by one. The needle spacer sleeve 1014 is installed on the convex ring 1011 by utilizing the interference fit between the clamping column and the blind hole 1016. When suturing the foreskin, the suture staple 1012 can continue to puncture the foreskin only after passing through the needle spacer sleeve 1014. The needle spacer sleeve 1014 can hide the suture staple 1012 before use to prevent the suture staple 1012 from piercing other objects.

[0048] like Figure 3 As shown, the front end of the ring-cut shell 100 is detachably provided with a protective cover 108 covering the convex ring 1011. Specifically, the protective cover 108 is preferably made of PVC material. The protective cover 108 is fixed to the front end of the ring-cut shell 100 so that the ring-cut shell 100 is in a closed state before use.

[0049] like Figure 7 As shown, the rear end of the limiting tube sleeve 103 is equipped with a rear opening limiting tube cover 1032 for closing the push groove 1031. The limiting tube cover 1032 is matched with the rear end of the limiting tube sleeve 103 by snapping together. The limiting tube cover 1032 has a through hole for movably passing the central axis 106. The aperture of the through hole is larger than the diameter of this section of the push rod. The setting of the limiting tube cover 1032 can prevent the excitation sleeve 104 from detaching from the push groove 1031 during use.

[0050] like Figure 6 and Figure 8A plurality of ring knife guide strips 1003 extending axially along the ring cutting shell 100 are provided at intervals on the inner wall of the ring cutting shell 100 in the circumferential direction, and the annular cutter 1022 is provided with a ring knife guide groove 10221 which corresponds one-to-one with the ring knife guide strips 1003 and cooperates in an axially movable and circumferentially locked manner.

[0051] In this embodiment, there are three ring knife guide strips 1003 and three ring knife guide grooves 10221. By cooperating with the ring knife guide strips 1003 and the ring knife guide grooves 10221, the ring cutting shell 100 can limit the moving direction of the ring cutter 1022, so that the ring cutter 1022 will not be circumferentially offset during the cutting process, thereby helping to improve the cutting accuracy of the ring cutter 1022.

[0052] like Figure 9 and Figure 10 As shown, it includes a pre-tensioning component 20 and a foreskin fixing ring 30, wherein the foreskin fixing ring 30 is used to fix the foreskin outside and cooperate with the circumcision suture part 10 to cut the foreskin, and the pre-tensioning component 20 is used to adjust the distance between the foreskin fixing ring 30 and the circumcision suture part 10 so that the foreskin fixing ring 30 contacts the circumcision suture part 10, and then the circumcision suture part 10 is used to remove the foreskin that has been turned outside.

[0053] Specifically, the pre-tensioning assembly 20 includes a handle-shaped shell 200, a knob 201, a movable sleeve 202 and a connecting rod 203. The front end of the handle-shaped shell 200 is detachably connected to the rear end of the ring-cut shell 100. Specifically, the handle-shaped shell 200 is buckled into two halves on the left and right. The front end of the handle-shaped shell 200 is provided with an inner cartridge, which is plugged into the connecting cylinder 1001 and locked by a tightening ring 111. The rear end of the central axis 106 has an external threaded portion 1062, and the external threaded portion 1062 is screwed with a knob. 201. The front part of the knob 201 is located in the rear end of the handle-shaped shell 200 and is connected to the handle-shaped shell 200 in a rotatable but non-movable manner. The rear part of the knob 201 extends out of the rear end of the handle-shaped shell 200. Specifically, an annular groove is provided in the rear end of the handle-shaped shell 200, and the knob 201 is provided with a rotating part 2011 that rotates with the annular groove. By cooperating between the rotating part 2011 and the annular groove and the protruding strip 1061 and the sliding groove 1023, the knob 201 can drive the central axis 106 to move forward and backward during the rotation process.

[0054] like Figure 2 、 Figure 9 and Figure 10As shown, the outer wall fixed sleeve of the central axis 106 is provided with a movable sleeve 202 fixedly connected to the connecting rod 203 and slidingly matched with the handle-shaped shell 200, and the handle-shaped shell 200 is circumferentially spaced apart with adjustment holes 2001 extending along the axial direction corresponding to the movable sleeve 202. The length of the adjustment hole 2001 is greater than the maximum distance between the front end face of the annular suture portion 10 and the rear end face of the annular suture portion 10. The connecting rods 203 correspond to the adjustment holes 2001 one by one, and one end of each connecting rod 203 extends into an adjustment hole 2001 and is fixedly connected to the movable sleeve 202, and the other end of each connecting rod 203 is detachably connected to the foreskin fixing ring 30.

[0055] like Figure 9 As shown, the limiting sleeve 103 is located in the handle-shaped shell 200 , and the handle-shaped shell 200 has a through hole 2002 for penetrating the connection portion between the firing handle 109 and the excitation sleeve 104 .

[0056] In the embodiment of the present application, the foreskin fixing ring 30 is consistent with the foreskin fixing ring 30 in the applicant's authorized patent for a circumcision suture device (CN2019214572199), so it will not be described in detail.

[0057] The present application discloses a press-trigger type foreskin eversion circumcision suture device. When used:

[0058] 1. First, pass the glans through the foreskin fixing ring 30 and directly enter the fixing cover 101. Then, turn the foreskin outward and stick it to the outer wall of the foreskin fixing ring 30. The operator intuitively adjusts the distance between the inner and outer foreskin plates and the coronal sulcus, as well as the reserved length of the glans frenulum. After adjusting to the appropriate position, use a strapping tape to fix the foreskin to be cut to the fixing ring groove of the foreskin fixing ring 30. Then, fix the foreskin fixing ring 30 to the three connecting rods 203.

[0059] 2. Then, rotate the knob 201 to move the central axis 106 backward, and use the three connecting rods 203 to move the foreskin fixing ring 30 and the fixing cover 101 closer together, thereby compacting and thinning the foreskin to be removed, making it easier to cut later;

[0060] 3. Press the firing handle 109 by hand to push the trigger sleeve 104 forward, thereby driving the nail push shield tube 102 to move forward. The blade of the annular cutter 1022 presses on the foreskin and, together with the cutting gasket of the foreskin fixing ring 30, further thins the foreskin and cuts through the barrier wall to enter the annular cutting groove. The foreskin is quickly cut off by the shear force of the annular cutter 1022 and the annular groove. At the same time, the push strip 1021 pushes the suture nail 1012 in the needle hole 1013 out to cooperate with the nail groove of the foreskin fixing ring 30 to sew the foreskin. In this process, the foreskin can be circumcised and sutured at one time.

[0061] 4. Release the firing handle 109 . Under the action of the reset spring 105 , the nail push cover tube 102 is reset. The knob 201 is rotated in the opposite direction, and the central axis 106 moves backward, so that the foreskin fixing ring 30 leaves the fixing cover 101 .

[0062] Based on the above, compared with the existing circumcision suture part 10, the central axis 106 of the present invention is movable through the handle-shaped shell 200, the movable sleeve 202, the limiting sleeve 103, the nail push cover tube 102 and then slidably connected to the fixed cover 101. The central axis 106 provides a stable support for the handle-shaped shell 200, the movable sleeve 202, the limiting sleeve 103 and the nail push cover tube 102, which helps to improve the stability of the circumcision suture device. At the same time, the central axis 106 replaces the existing circumcision suture device (CN2 019214572199) multiple connecting parts (mainly moving push rods and tensioning rods) that are connected in a coordinated manner further improve the stability of the circumcision suture device. Therefore, the press-trigger type foreskin eversion circumcision suture device has higher stability. At the same time, the ring knife guide strip 1003 cooperates with the ring knife guide groove 10221 to limit the moving direction of the ring knife 1022, so that the ring knife 1022 can slide accurately during the cutting process, which helps to improve the cutting accuracy of the ring knife 1022. In summary, the circumcision suture part of the present application has better stability and higher cutting accuracy.

[0063] The technical solution of this application has been described in detail above in conjunction with specific embodiments. The specific embodiments described are used to help understand the concept of this application. Derivations and modifications made by those skilled in the art based on the specific embodiments of this application also fall within the scope of protection of this application.
