Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and relates to a circumcision anastomat. BACKGROUND

[0002] The circumcision anastomat is a special medical device for treating redundant prepuce or phimosis, and is widely used in clinical application at present. Compared with the traditional manual resection and suture operation which is complicated to operate, the circumcision anastomat can improve the operation precision, shorten the operation time, and reduce postoperative complications.

[0003] The existing circumcision anastomat mainly includes five core components: a shell assembly, a glans protection device, a circumcision mechanism, a fixing member, and a driving control mechanism. During the operation, the glans protection device is first placed into the prepuce cavity to cover the glans and avoid accidental injury, then the prepuce is evenly distributed outside the protection device through the fixing member, and finally the circumcision mechanism is driven to complete the cutting and suture / anastomosis of the prepuce tissue.

[0004] Among them, the suture / anastomosis of the prepuce tissue is mainly realized by the suture nails in the circumcision anastomat, such as titanium nails or absorbable nails. These suture nails need to be self-shedded for 2-3 weeks or removed by a doctor. During the period of not shedding, the suture nails are exposed on the surface of the glans, and are easy to produce friction in the daily activities of the patient, which can easily lead to the early shedding of the suture nails and cause the problems of wound cracking and bleeding. In addition, even after self-shedding or removal, the suture nails may have the problem of foreign body residue, which can cause rejection reaction. SUMMARY

[0005] To solve the above problems, the present application provides a circumcision anastomat which can complete the circumcision and anastomosis with high precision and simple operation, and can also use absorbable thread to replace the suture nails.

[0006] The present application specifically provides a circumcision anastomosis device for performing circumcision anastomosis, characterized in that it comprises: a positioning member for positioning a foreskin part to be removed from a patient; a housing having a cooperating end cooperating with the positioning member; a circumcision member for circumcising the foreskin part so that the circumcised part forms a suture site; a suture member rotatably arranged in the housing, one end away from the cooperating end being provided with a suture knob; a plurality of first suture needles each having an arc-shaped needle part facing the cooperating end, and the arc-shaped needle part being provided with a first threading groove at a tip part and a wire clamping groove at a middle part; and a second suture needle arranged at one end of the suture member close to the cooperating end, and the end part close to the cooperating end being provided with a second threading groove, the wire clamping groove and the first threading groove of each first suture needle being collectively threaded with a first suture wire, and the second threading groove being threaded with a second suture wire, the circumcision anastomosis device further comprising a driving mechanism for driving the first suture needle to slide towards the cooperating end so that the arc-shaped needle parts collectively penetrate into the suture site, and the first suture wire is exposed from the suture site to form a plurality of loops, so that the second suture needle can be sequentially threaded through each loop under the driving of the suture member to complete suture.

[0007] In the circumcision anastomosis device of the present application, the positioning member can position the foreskin part, and the circumcision member can remove the positioned foreskin part, so that the foreskin part to be removed can be accurately positioned, and the cutting precision is high. The first threading groove and the wire clamping groove on the arc-shaped needle part of the plurality of first suture needles are collectively threaded with the first suture wire, which can collectively penetrate into the suture site under the driving of the driving mechanism to form a plurality of loops, and the second suture needle arranged on the suture member is threaded with the second suture wire, which can be sequentially threaded through each loop under the driving of the suture member to make the second suture wire cooperate with the loops of the first suture wire to complete suture, so that the circumcision anastomosis device of the present application can complete circumcision and anastomosis at one time through relatively simple operation, and the suture operation can be completed only by using the suture wire without using the suture needle.

[0008] Compared with the traditional manual suture, the circumcision anastomosis device of the present application is simple in operation and high in precision, and compared with the device of the prior art, the present application does not need to use the suture needle, which can avoid the problems of falling off, wound cracking and foreign body residue caused by the suture needle.

[0009] In the circumcision anastomosis device of the present application, the driving mechanism can comprise: a sliding block arranged in the housing at a position close to the cooperating end and capable of sliding in a direction towards the cooperating end; a connecting rod rotatably connected at one end to the sliding block; and a trigger rotatably connected to the connecting rod, and the first suture needle has a connecting part connecting the sliding block and the arc-shaped needle part. Further, the housing can further have a handle part, and the middle part of the trigger can be hinged to the handle part.

[0010] By connecting the arc-shaped needle portions to the slider through the connecting portions, and connecting the slider and the connecting rod to the trigger respectively, the medical staff can drive the slider to move by pressing or pulling the trigger, and drive the arc-shaped needle portions to move. Thus, a plurality of first suture needles can be driven to move together by one operation, and the corresponding action in the suturing process can be realized. In addition, the trigger is hinged to the handle portion of the shell, so that the operation force of pressing the trigger can be more easily applied.

[0011] The foreskin circumcision anastomosis device provided by the application can further have the following technical features: the driving mechanism further comprises a guide block mounted on the matching end and having a plurality of guide grooves respectively used for guiding the first suture needles, the guide grooves are arc-shaped and have a curvature matched with the arc-shaped needle portions. The guide grooves are matched with the arc-shaped needle portions, so that the arc-shaped needle portions can move in the guide grooves along a predetermined path when being driven by the slider, and the accuracy of the puncture positions of the arc-shaped needle portions on the parts to be sutured can be ensured.

[0012] Further, the foreskin circumcision anastomosis device provided by the application can further have the following technical features: the positioning member comprises a plate portion, a through hole through which the penis of a patient passes is formed in the middle portion of the plate portion, a support ring is arranged on the plate portion and surrounds the through hole, and the support ring is used for folding and positioning the foreskin portion, a plurality of position-allowing notches are further arranged on the support ring, and the plurality of position-allowing notches correspond to the positions of the guide grooves one by one.

[0013] The structure design of the positioning member including the support ring can effectively support the foreskin portion, and the circumcision and subsequent suturing can be more easily realized. In addition, since the position-allowing notches correspond to the positions of the guide grooves one by one, when the arc-shaped needle portions puncture the parts to be sutured by being guided by the guide grooves, the positions of the arc-shaped needle portions entering the parts to be sutured are located at the position-allowing notches, and the arc-shaped needle portions are not hindered by the support ring.

[0014] In addition, the foreskin circumcision anastomosis device provided by the application can further have the following technical features: the shell has a shell main body portion in a cylindrical shape and an inner cylinder portion located in the shell main body portion, and the slider is arranged in the shell main body portion and is sleeved outside the inner cylinder portion. By sleeving the slider between the inner cylinder portion and the shell main body portion, the movement of the slider can be limited by the inner cylinder portion and the shell main body portion, so that the problem of the slider being inclined or skewed to cause inconsistent movements of the arc-shaped needle portions can be avoided, and the consistency of the puncture positions of the arc-shaped needle portions during suturing can be ensured.

[0015] In addition, the foreskin circumcision anastomat further has the technical features that the circumcision member comprises a circumcision screw located in the inner cylinder and threadedly engaged with the inner cylinder, a circumcision knob fixed to the end of the circumcision screw away from the engaging end, and a circumcision blade provided at the end of the circumcision screw close to the engaging end. Further, a plurality of barbs can be provided on the outer circumferential surface of the circumcision blade. In the present application, the circumcision screw is threadedly engaged with the inner cylinder, so that the rotation of the circumcision knob can drive the circumcision blade to move axially to complete the cutting, which is simple and easy to operate and unlikely to cause cutting misalignment. In addition, the barbs can drive the cut foreskin to be taken away by the circumcision blade, avoiding the hindrance to the subsequent suturing operation.

[0016] In addition, the foreskin circumcision anastomat further has the technical features that the second suture needle is in the shape of a spiral line. The spiral-shaped second suture needle can form a ring-like shape in the circumferential direction at the thread end and other parts of the second suture line, so that the rotation of the suture member can drive the second suture line to enter the respective loops formed by the first suture line in sequence, and the first suture line and the second suture line can be combined to complete the suturing without complex operation.

[0017] In addition, the foreskin circumcision anastomat further has the technical features that the circumcision member forms an accommodating cavity extending axially therethrough, the suture member further has a connecting rod fixedly connected with the second suture needle, the suture knob is located at the end of the connecting rod away from the engaging end, and the connecting rod is arranged in the accommodating cavity and can rotate in the accommodating cavity. By arranging the connecting rod of the suture member in the accommodating cavity of the circumcision member, the suture member can rotate relative to the circumcision member, and the movements of the two members are independent of and do not interfere with each other, which can reduce the operation error and complete the suturing with higher precision.

DETAILED DESCRIPTION

[0034] The specific embodiment of the present application is described below in combination with the drawings and the embodiments.

[0035] <EMBODIMENT>

[0036] Figure 1 is the structure diagram of the prepuce circumcision anastomosis device of the embodiment of the present application, Figure 2is a use schematic view of the circumcision anastomat device of the embodiment of the present application, Figure 3 is a sectional view of the circumcision anastomat device of the embodiment of the present application.

[0037] As Figures 1-3 shown, the circumcision anastomat device 100 (hereinafter referred to as device 100) of the embodiment is used for circumcision anastomosis of the penis 200 of a patient, which comprises a positioning member 1, a shell 2, a circumcision member 3, a first suture needle 4, a driving mechanism 5, a suture member 6 and a second suture needle 7. Figure 3 In the figure, the driving mechanism 5 and the first suture needle 4 are omitted in order to show the cooperation relationship of some components.

[0038] Figure 4 is a structure diagram of the positioning member of the embodiment of the present application, Figure 5 is a use schematic view of the positioning member of the embodiment of the present application.

[0039] As Figure 4 , 5 shown, the positioning member 1 comprises a plate part 11 and a support ring 12. Among them, the plate part 11 is circular, and a through hole 111 is provided in the middle part, which is matched in size with the size of the penis 200 and can pass through the penis 200. A plurality of clamping protrusions 112 are also uniformly distributed on the side surface periphery of the plate part 11.

[0040] The support ring 12 is annular, which is arranged on the plate part 11 and located on the same side surface as the clamping protrusion 112 and surrounds the through hole 111.

[0041] As Figure 5 shown, the positioning member 1 needs to first let the glans part pass into the through hole 111 from the other side surface of the surface where the support ring 12 is located when in use, so that the glans part is exposed outside the support ring 12, and then the foreskin part 201 to be cut is folded outward to the outer surface of the support ring 12, that is, the positioning is completed.

[0042] In the embodiment, six position-providing notches 121 are also provided on the support ring 12, which are uniformly distributed on the support ring 12 in the circumferential direction, and each position-providing notch 121 extends from one end of the support ring 12 away from the plate part 11 towards the plate part 11.

[0043] As Figures 1-3 shown, the shell 2 comprises a shell main body part 21, a handle part 22 and an inner cylinder part 23.

[0044] The shell main body part 21 is generally cylindrical, and the opening inner diameter of one end part thereof is matched with the diameter of the plate part 11, and the end part serves as a cooperation end 211 for cooperation with the positioning member 1.

[0045] The handle portion 22 is located on the side of the housing body portion 21, and a hinge seat 221 is provided on the surface of the handle portion 22 facing the mating end 211.

[0046] The inner cylinder 23 is cylindrical, with an outer diameter smaller than the inner diameter of the shell body 21 and a length approximately half that of the shell body 21, and is disposed inside the shell body 21.

[0047] A retaining ring 231 is provided at one end of the inner cylinder portion 23 away from the mating end 211. The outer edge of the retaining ring 231 matches the shape of the inner surface of the shell body portion 21 and is fixed to the inner surface of the shell body portion 21, so that the inner cylinder portion 23 can be positioned relative to the shell body portion 21. In this embodiment, the central axis of the inner cylinder portion 23 coincides with the central axis of the shell body portion 21.

[0048] Figure 6 This is a structural diagram of the circumferential cutter according to an embodiment of the present invention.

[0049] like Figure 3 , 6 As shown, the circumferential cutting component 3 includes a circumferential cutting screw 31, a circumferential cutting knob 32, and a circumferential cutting blade 33.

[0050] like Figure 3 As shown, the circumferential screw 31 has a hollow structure and is located inside the inner cylinder 23. Its outer diameter is approximately matched with the inner diameter of the inner cylinder 23. The outer surface of the circumferential screw 31 has an external thread, and the inner surface of the inner cylinder 23 has an internal thread that matches the external thread. Through the threaded engagement of the two, the circumferential screw 31 can move back and forth along the axial direction when it is rotated.

[0051] The circumferential cutting knob 32 is fixed to the end of the circumferential cutting screw 31 away from the mating end 211, and its central part has a hole identical to the internal cavity of the circumferential cutting screw 31. When the circumferential cutting knob 32 is turned by a medical professional, it drives the circumferential cutting screw 31 to rotate, causing the circumferential cutting screw 31 to move towards or away from the mating end 211. Figures 1-2 As shown, the side of the shell body 21 is provided with a hollowed-out operation window 212, and the position of the circumferential knob 32 corresponds to the operation window 212, so that it can be exposed through the operation window 212 for medical personnel to rotate.

[0052] Figure 7 This is a schematic diagram of the circumferential cutting operation according to an embodiment of the present invention.

[0053] like Figure 6 , 7As shown, the ring cutter screw 31 is provided with a ring blade 33 on the end of the mating end 211. The ring blade 33 is annular, and the blade surface is on the side facing the mating end 211. The inner diameter of the ring cutter screw 31 and the ring blade 33 is slightly larger than the outer diameter of the support ring 12. When the medical staff rotates the ring cutting knob 32 to move the ring cutter screw 31 towards the mating end 211, the blade surface of the ring blade 33 can contact the foreskin portion 201 on the support ring 12 to cut the foreskin portion 201.

[0054] The outer periphery of the ring blade 33 is provided with a plurality of barbs 331. During the cutting of the foreskin portion 201, the ring blade 33 is cut into between the foreskin portion 201 and the outer surface of the support ring 12; when the medical staff reversely rotates the ring cutting knob 32 to move the ring cutter screw 31 and the ring blade 33 away from the mating end 211, the cut foreskin portion 201 is hung by the barbs 331, and the ring blade 33 is moved away from the support ring 12 together. After cutting, the penis 200 and the cut position need to be sutured, which is the suture site.

[0055] Figure 8 is a first suture needle structure diagram of an embodiment of the present application, Figure 9 is a suture schematic diagram of the present application, Figure 9 The ring cutter 3 is omitted in the present application.

[0056] As Figure 2 , 8 As shown in -9, a plurality of first suture needles 4 are arranged inside the mating end 211. Each first suture needle 4 is composed of an arc-shaped needle part 41 and a connecting part 42. In the present embodiment, the number of first suture needles 4 is consistent with the accommodation gap 121, i.e. there are six first suture needles 4 in total.

[0057] The arc-shaped needle part 41 is in the shape of an approximate circular arc, and is arranged towards the mating end 211 (i.e. the tip end is close to the mating end 211), and is used to pierce the suture site. The tip end of the arc-shaped needle part 41 is provided with a first threading groove 411, and a hooking groove 412 is also arranged at the middle position.

[0058] The first suture line 301 is one in number, and is collectively arranged on the six first suture needles 4 arranged on the arc-shaped needle part 41. The arrangement is as follows: first, the first suture line 301 is clamped into the line hooking groove 412 of the first first suture needle 4, then is pulled along the arc-shaped needle part 41, so that the first suture line 301 passes through the first thread passing groove 411 of the first suture needle 4, is folded back after forming a loop 302 at the thread passing hole 411, is pulled back to the line hooking groove 412 along the arc-shaped needle part 41, and is clamped into the line hooking groove 412 again; then, the first suture line 301 is pulled along the circumference, is clamped into the line hooking groove 412 of the next first suture needle 4, and is continuously pulled to the first thread passing groove 411 of the first suture needle 4, so as to form a second loop 302 according to the foregoing operation. In sequence, the first suture line 301 is sequentially formed into loops 302 at the first thread passing groove 411 of each first suture needle 4, and is led out at the line hooking groove 412 of the last first suture needle 4. After the arrangement is completed, each loop 302 can be gently pulled to make the loop 302 open and larger in size, so as to facilitate subsequent suturing operation.

[0059] The connecting part 42 is approximately linear, and the end part is connected with the arc-shaped needle part 41. The part connected with the arc-shaped needle part 41 is in an arc shape with a curvature basically same as that of the arc-shaped needle part 41, and the other part is in a linear shape. In the embodiment, the connecting part 42 is composed of a super-elastic nickel-titanium alloy wire.

[0060] Figure 10 FIG. 4 is a schematic view of cooperation between the arc-shaped needle part and the driving mechanism of the embodiment of the application.

[0061] As shown in FIG. 10, the driving mechanism 5 comprises a guide block 51, a sliding block 52, a connecting rod 53, and a wrench 54. Figure 1 , 9 As shown in FIG. 10, the driving mechanism 5 comprises a guide block 51, a sliding block 52, a connecting rod 53, and a wrench 54.

[0062] The guide block 51 is in a cylindrical shape, is installed in the cooperation end 211, and is fixed on the inner cylinder part 23 at the end part away from the cooperation end 211. The end part of the guide block 51 facing the positioning member 1 is provided with a plurality of engaging recesses 511 matched with the engaging protrusions 112 respectively. By clamping the engaging protrusions 112 into the engaging recesses 511 respectively, the positioning member 1 can be positioned at the guide block 51. In this state, the support ring 12 and the penile head part located in the support ring 12 are located in the guide block 51. In addition, the inner diameter of the guide block 51 is larger than the outer diameter of the support ring 12, so that when the positioning member 1 is positioned at the guide block 51, a larger space is left between the guide block 21 and the support ring 12.

[0063] As shown in FIG. 10, the driving mechanism 5 comprises a guide block 51, a sliding block 52, a connecting rod 53, and a wrench 54. Figures 9-10As shown, six guide grooves 513 for guiding the first suture needles 4 respectively are also arranged in the guide block 51, and the guide grooves 513 are in arc shape matching the curvature of the arc needle portion 41. The opening of each guide groove 513 on the side of the fitting end 211 faces the radial inner side, each first suture needle 4 is accommodated in the corresponding guide groove 513 respectively, and the needle tip end of the arc needle portion 41 is exposed from the opening on the fitting end side of the guide groove 513.

[0064] In the present embodiment, the number of the engaging protrusions 112 and the engaging recesses 511 is six, and they are uniformly distributed in the circumferential direction, so the cooperation of the two also plays a positioning role in the circumferential direction of the positioning member 1 relative to the guide block 51. When the positioning member 1 is positioned at the guide block 51, the guide grooves 513 and the relief notches 121 are one-to-one corresponding.

[0065] In the present embodiment, the guide block 51 is a split structure, which is composed of six guide block portions 512 of the same shape, and the six guide grooves 513 are one-to-one corresponding to the six guide block portions 512 and are arranged in the corresponding guide block portions 512 respectively. By arranging the guide grooves 513 in each guide block portion 512 respectively, the installation and combination of the guide block 51 are more convenient. As an alternative, the guide block 51 can also be a one-piece structure, that is, composed of one integrally formed cylindrical component.

[0066] The slider 52 is arranged in the shell main body portion 21 and is sleeved outside the inner cylinder portion 23. The inner diameter of the slider 52 matches the outer diameter of the inner cylinder portion 23, and the outer diameter matches the inner diameter of the shell main body portion 21, so the slider 52 can slide back and forth along the axial direction between the inner cylinder portion 23 and the shell main body portion 21. The end of each connecting portion 42 away from the arc needle portion 41 is fixedly connected to the slider 52, so the first suture needle 4 can move with the back and forth sliding movement of the slider 52. In addition, in the present embodiment, the end of the inner cylinder portion 23 close to the fitting end 211 is provided with an outward flange 232, which limits the sliding movement of the slider 52 towards the fitting end 211.

[0067] As shown in FIG. 6, the first suture needle 4 is in the form of a needle with a needle body 411 and a needle tip end 412. The needle body 411 is in arc shape, and the curvature of the needle body 411 matches the curvature of the arc needle portion 41. The needle body 411 is fixedly connected to the connecting portion 42, and the needle tip end 412 is exposed from the opening on the fitting end side of the guide groove 513. Figure 9As shown, when the slider 52 slides towards the fitting end 211, the connecting portion 42 is driven to move towards the fitting end 211, so that the connecting portion 42 drives the arc-shaped needle portion 41 to move in the guide slot hole 513. Since the arc-shaped needle portion 41 and the guide slot hole 513 are both arc-shaped, the movement track of the arc-shaped needle portion 41 is also arc-shaped, and correspondingly, the needle tip end of the arc-shaped needle portion 41 can move from the fitting end side opening of the guide slot hole 513 to the support ring 12, and after being pierced into the to-be-sutured part, it will be pierced out at a position slightly away from the fitting end. With the performance of the piercing action, the first suture line 301 will also be partially penetrated into the to-be-sutured part and then penetrated out, so that each coil 302 is exposed outside the to-be-sutured part together with the needle tip end. In addition, since the positions of the guide slot holes 513 correspond to each of the accommodation notches 121 respectively, the piercing, piercing-out and other actions of the arc-shaped needle portion 41 are performed at the accommodation notches 121, and the movement is not hindered by the support ring 12.

[0068] One end of the connecting rod 53 is rotatably connected to the slider 52, and the other end is rotatably connected to the wrench 54, and the middle part of the wrench 54 is hinged to the hinge seat 221. When the wrench 54 is pressed, the rotation of the wrench 54 drives the connecting rod 53 to rotate, and then drives the slider 52 to slide towards the fitting end 211; on the contrary, when the wrench 54 is pulled up, the slider 52 can be driven to slide away from the fitting end 211.

[0069] As shown in Figure 3 , 9 The suture piece 6 includes a connecting rod 61, a suture knob 62 and an embedded plate 63.

[0070] In this embodiment, the hollow structure of the ring cutting screw 31, the hole inner diameter of the ring cutting knob 32 and the inner diameter of the ring blade 33 are basically the same, so that the ring cutting screw 31, the ring blade 33 and the inside of the ring cutting knob 32 form a cavity which is uniformly penetrated in the axial direction, that is, the accommodation cavity 34.

[0071] The connecting rod 61 is arranged in the accommodation cavity 34 and can rotate in the accommodation cavity 34.

[0072] The suture knob 62 is arranged on the end part of the connecting rod 61 and located outside the end part of the shell main body part 21 away from the fitting end 211, and can drive the connecting rod 61 to rotate.

[0073] The embedded plate 63 is annular plate-shaped and fixedly arranged on the outer surface of the connecting rod 61 close to the suture knob 62. The inner surface of the shell main body part 21 is provided with an annular groove 24 matched with the embedded plate 63, and the outer edge part of the embedded plate 63 is embedded in the annular groove 24, so that the connecting rod 61 can rotate more stably in the shell main body part 21.

[0074] Figure 11 is a structure diagram of a second suture needle and a second suture line of an embodiment of the present application,Figure 12 is a schematic diagram of the stitching action of the second suture needle of the embodiment of the present application.

[0075] As shown in Figure 9 , 11 As shown in FIG. 12, the second suture needle 7 is in a helical shape, one end of which is provided with a second threading groove 71 and threaded with a second suture thread 303, and the other end of which is fixed to the connecting rod 61. When the connecting rod 61 is rotated under the driving of the suture knob 62, the second suture needle 7 rotates accordingly, so that the thread end of the second suture thread 303 also rotates, thereby being able to pass through each loop 302 in turn.

Figure 13 In the embodiment of the present application, the second suture needle 7 is omitted, Figure 14 In the embodiment of the present application, the knot of the suture thread is omitted.

[0077] As shown in Figures 13-14 After the second suture thread 303 passes through the six loops 302, the wrench 54 is pulled in reverse to move the slider 52 away from the mating end 211, thereby driving each first suture needle 4 to retreat to the initial position along the guide slot hole 513. Since the second suture thread 303 has already been threaded into each loop 302, the loop 302 part will not retreat with the retreat of the first suture needle 4, but will be detached from each first threading groove 411 and the thread clamping groove 412. After the first suture needle 4 exits the suture part to be sutured, the first suture thread 301 is manually pulled tight, so that the first suture thread 301 tightly wraps the second suture thread 303. At this time, the suture knob 62 is reversed to rotate, so that the second suture needle 7 exits and the second suture thread 303 is detached from the second suture needle 7 by the frictional force of the first suture thread 301 and remains in place. Subsequently, the first suture thread 301 and the second suture thread 303 can be pulled tight again and knotted.

[0078] The working process of the device 100 of the embodiment will be specifically described below.

[0079] Before starting, the threading action of the first suture thread 301 and the second suture thread 303 needs to be completed first, that is, the first suture thread 301 is threaded on each first suture needle 4 to form a loop 302, and the second suture thread 303 is threaded on the second suture needle 7. Then, the following procedures are operated:

[0080] Step 1, pass the penis 200 of the patient through the positioning member 1, and fold the foreskin part 201 to be removed outward to the outer surface of the support ring 12;

[0081] Step 2, respectively insert each clamping protrusion 112 into the clamping recess 511, so as to position the positioning member 1 at the guide block 51;

[0082] Step 3, rotate the ring cutting knob 32 to move the ring cutting screw 31 towards the mating end 211, so that the ring blade 33 cuts the foreskin part 201 folded on the outer surface of the support ring 12, and the cut part is the suture site;

[0083] Step 4, reverse rotation of the ring cutting knob 32, so that the ring cutting screw 31 moves away from the mating end 211, and the ring blade 33 carries the cut foreskin part 201 away through the barb 331;

[0084] Step 5, press the wrench 54 to move the slider 52 towards the mating end 211, and the arc needle part 41 pierces into the suture site and then pierces out, forming each loop 302 outside the suture site;

[0085] Step 6, rotate the suture knob 62 to pass the second suture line 303 through each loop 302 in turn;

[0086] Step 7, pull the wrench 54 to move the slider 52 away from the mating end 211, so that the arc needle part 41 exits the suture site while the first suture line 301 is separated from the first threading groove 411 and the wire retaining groove 412;

[0087] Step 8, tighten the first suture line 301;

[0088] Step 9, reverse rotation of the suture knob 62, so that the second suture needle 7 exits while the second suture line 303 remains in place;

[0089] Step 10, tighten the first suture line 301 and the second suture line 303 and tie a knot, completing the anastomosis operation.

[0090] After the above process is completed, the positioning member 1 can be separated from the guide block 51, and the positioning member 1 is removed from the penis 200, completing the entire ring cutting anastomosis operation process.
