Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and more particularly to a circumcision suturing device structure and an operating method thereof with a high-efficiency suturing function. Background Art
[0002] In the field of medical device technology, circumcision staplers are an important surgical instrument widely used in circumcision procedures. Traditional circumcision procedures typically require doctors to manually cut and sew, which is complex and time-consuming. Furthermore, the cutting accuracy and suturing effect during the operation are largely dependent on the doctor's personal experience and technical level, which brings greater surgical risks and difficult postoperative recovery to patients.
[0003] With the continuous advancement of medical technology, some new circumcision suture devices have appeared on the market. These instruments have simplified surgical operations to a certain extent and improved surgical efficiency. However, the circumcision suture devices currently on the market still have many technical defects. For example, the cutting and suturing actions of some suture devices are difficult to synchronize accurately, resulting in tissue dislocation, which not only affects the surgical effect, but may also increase postoperative infection and recovery difficulty. In addition, the cutting blade design of some suture devices is unreasonable and the cutting resistance is large, which not only reduces the cutting efficiency but also easily causes excessive tissue damage, increasing the patient's pain and postoperative recovery time. In addition, the overall structural design of some suture devices is not stable enough, the tensile strength is insufficient, and it is difficult to adapt to high-tension surgical environments. There is a risk of breakage, which poses a hidden danger to surgical safety.
[0004] Therefore, a circumcision suture device structure and operation method with high-efficiency suturing function are proposed. Summary of the Invention

[0015] A method for operating the circumcision suturing device structure with a high-efficiency suturing function according to the above-mentioned method comprises the following steps:

[0025] 4. The glans seat adopts an integrated structural design of a bell-shaped base, double-headed screw and rubber-coated parts. The tensile strength is increased by about 30% through the reinforcement of the ribs and rubber-coated layer. It is suitable for high-tension surgical environments and reduces the probability of breakage.
[0026] 5. By setting the inlay fit between the T-shaped clamp and the T-shaped slot, and the screw fixation of the locking sleeve, compared with the traditional connection structure, the connection fixity and the withstanding tensile force between the pull rod and the glans seat are significantly improved, and the maximum withstanding tensile force value reaches 7000N.
[0027] 6. The design of the retaining ring effectively prevents the locking sleeve from sliding, further enhancing the firmness of the connection.

DETAILED DESCRIPTION
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0037] As attached Figure 1 - Figure 7 The structure of a circumcision suture device with an efficient suturing function shown in the figure includes a glans seat 1 and a pull rod 2, the glans seat 1 is connected to the pull rod 2, the bottom end of the glans seat 1 is fixedly connected to a bottom rod 12, the bottom of the bottom rod 12 is provided with a T-shaped through slot 5, the top of the pull rod 2 is provided with a T-shaped clamp 8, the T-shaped clamp 8 is embedded in the T-shaped through slot 5, and a locking sleeve 3 is screwed on the connection between the T-shaped clamp 8 and the T-shaped through slot 5, the bottom end of the pull rod 2 is provided with a screw head 4, the screw head 4 is connected to a fixing sleeve 13, a top body 16 is sleeved on the fixing sleeve 13, a cutting knife 17 is installed on the inner side of the top body 16, a pushing sleeve 14 is sleeved on the outer side of the top body 16, and an annular nail magazine 15 is provided on the top of the pushing sleeve 14.
[0038] During specific implementation, the screw head 4 at the bottom of the pull rod 2 is connected and fixed with the fixing sleeve 13, the cutting knife 17 is fixed on the top body 16, and the suture nails are placed in the annular nail magazine 15. During the operation, the top body 16 is pushed out, and the cutting knife 17 and the suture nails will be pushed out together by the top body 16 for cutting and suturing, and the operation can be completed. When assembling the glans seat 1 and the pull rod 2, the T-shaped clamp 8 is slid into the T-shaped through groove 5, and the inclined surface of the locking head 9 is subjected to pressure, so that the bottom plate 11 descends in the cylindrical screw groove and the spring is compressed. As the T-shaped clamp 8 moves in, when the locking head 9 moves to the locking groove 6 position, the spring potential energy is released, and the locking head 9 is inserted into the locking groove 6, thereby avoiding the T-shaped clamp 8 from being difficult to control when the moving position is embedded, so that the embedded position of the T-shaped clamp 8 can be positioned, ensuring that the pull rod 2 and the bottom rod 12 can be coaxial, improving the tensile strength that can be withstood, and at the same time, it is convenient to screw the locking sleeve 3, thereby improving the convenience of installation.
[0039] The diameter of the pull rod 2 is smaller than the diameter of the bottom rod 12 . A retaining ring 7 is provided at the top of the pull rod 2 . The locking sleeve 3 is sleeved on the pull rod 2 . The locking sleeve 3 is blocked by the retaining ring 7 from being screwed onto the bottom rod 12 .
[0040] In a specific implementation, the diameter of the pull rod 2 is smaller than the diameter of the bottom rod 12, so that the locking sleeve 3 slidably connected to the pull rod 2 can slide on the pull rod 2 at will, and cooperate with the retaining ring 7 to block it. When the locking sleeve 3 is screwed onto the bottom rod 12, the bottom rod 12 can be pulled down under the blockage of the retaining ring 7, thereby improving the connection strength between the pull rod 2 and the bottom rod 12.
[0041] A cylindrical screw groove is provided at the top of the T-shaped clamp 8, a spring is placed at the bottom end of the cylindrical screw groove, the top end of the spring supports a base plate 11, a locking head 9 is coaxially fixed to the base plate 11, a locking cap 10 is sleeved on the locking head 9, and the locking cap 10 is screwed into the cylindrical screw groove.
[0042] In specific implementation, when the T-shaped clamp 8 is slid into the T-shaped through groove 5, the inclined surface of the lock head 9 is subjected to pressure, and the bottom plate 11 is lowered in the cylindrical screw groove, which compresses the spring. As the T-shaped clamp 8 moves in, when the lock head 9 moves to the lock groove 6 position, the spring potential energy is released, and the lock head 9 is inserted into the lock groove 6, thereby avoiding the difficulty in controlling the moving position when the T-shaped clamp 8 is embedded, so that the embedded position of the T-shaped clamp 8 can be positioned, ensuring that the pull rod 2 and the bottom rod 12 can be coaxial, improving the tensile strength that can be withstood, and at the same time, facilitating the screw connection of the locking sleeve 3, improving the convenience of installation.
[0043] A locking groove 6 is formed at the top of the T-shaped through groove 5 , and the locking head 9 is plugged into and matched with the locking groove 6 .
[0044] In specific implementation, by inserting the lock head 9 into the lock groove 6, the connection between the T-shaped through groove 5 and the T-shaped clamp head 8 can be slidably limited, thereby facilitating the installation of the locking sleeve 3 and improving the convenience of installation.
[0045] The glans seat 1 is composed of a bell-shaped base, a double-headed screw and a rubber-coated part. The bell-shaped base and the double-headed screw are fixed by a plug gauge connection or an embedded connection, and an integrated structure is formed by a rubber-coated injection molding process.
[0046] In practice, the bell-shaped base and stud screw are connected via a plug gauge or insert, with the joint machined into a precision mortise and tenon structure. A medical-grade PC plastic overmolding is then injected into the joint using a vertical overmolding injection molding machine, forming an integrated structure. The overmolding covers the joint between the stud screw and bell-shaped base and fills the gaps between the reinforcing ribs. The plug gauge connection ensures axial alignment between the bell-shaped base and the screw, reducing assembly errors. The PC plastic fills the joint and solidifies, forming a flexible buffer layer that disperses tensile stress, thereby increasing the tensile strength to over 7,000N, completely eliminating the risk of rod breakage and enhancing the fatigue resistance of the joint, extending the life of the device.
[0047] A guide groove is provided between the top body 16 and the pushing sleeve 14 , and a protrusion is provided on the inner wall of the pushing sleeve 14 . The protrusion slides along the guide groove to control the synchronous advancement of the annular nail magazine.
[0048] During specific implementation, a longitudinal guide groove is provided on the outer wall of the top body 16, and a protrusion is provided on the inner wall of the pushing sleeve 14. When the top body 16 is pushed, the protrusion slides along the guide groove, forcing the pushing sleeve 14 and the top body 16 to move synchronously, driving the annular staple cartridge 15 to release the suture staples, so that the cooperation between the guide groove and the protrusion converts the linear motion of the top body 16 into the synchronous advancement of the pushing sleeve 14, so that the cutting and suturing actions are strictly synchronized, tissue dislocation is avoided, and the operation is smooth, reducing the complexity of the doctor's operation.
[0049] A reinforcing rib is provided at the connection between the double-headed screw and the bell-shaped base, and the rubber-coated part covers the connection part to enhance the tensile strength.
[0050] During specific implementation, annular reinforcement ribs are processed at the connection between the double-headed screw and the bell-shaped base, and the rubber coating covers the surface of the reinforcement ribs to form a multi-layer tensile structure. The reinforcement ribs increase the cross-sectional area of the connection part and disperse the stress concentration points, thereby increasing the tensile strength by 30%, making it suitable for high-tension surgical environments, and allowing the rubber coating layer to further absorb impact and reduce the probability of breakage.
[0051] The cutting knife 17 is an annular blade, the inner diameter of which matches the outer diameter of the glans seat 1, and the blade inclination angle is 15°-25°, which is used to achieve efficient cutting and hemostasis.
[0052] During specific implementation, the cutting knife 17 is annular in structure, the inner diameter matches the outer diameter of the glans seat 1, the blade inclination angle is designed to be 20°, the blade is laser-ground using medical stainless steel, and the edge thickness is ≤0.1mm. The cutting resistance is reduced by tilting the blade, achieving a "sliding cutting" effect, reducing tissue damage, and increasing the cutting efficiency by 40%, reducing intraoperative bleeding, and making the incision smooth, which is conducive to postoperative healing.
[0053] The annular staple cartridge 15 is embedded with a plurality of medical staples, which are arranged radially, and the ends of the staples are provided with barbs to enhance the fixing effect.
[0054] During specific implementation, 24 groups of suture staples are embedded in the annular staple cartridge 15 and arranged radially. Barbs are processed at the ends of the staple feet. The barb angle is 45° and the length is 0.5 mm. They are radially distributed to evenly cover the circumference of the incision, ensuring that there are no dead angles for hemostasis. The barbs are used for anchoring, so that the barbs are embedded in the tissue to form a mechanical lock to prevent the suture staples from falling off, thereby accelerating the hemostasis speed and reducing the risk of postoperative infection, thereby improving the stability of the suture and eliminating the need for secondary reinforcement.
[0055] A method for operating a circumcision suture device structure with a high-efficiency suturing function comprises the following steps:
[0056] Step 1: Place the glans seat 1 on the patient's glans, adjust the position of the pull rod 2 and secure it with the locking sleeve 3;
[0057] Step 2: Rotate the screw head 4 to drive the fixing sleeve 13 to drive the top body 16 to advance, so that the cutting knife 17 and the annular nail magazine 15 move synchronously;
[0058] Step 3: The optical axis of the top body 16 and the optical axis of the glans base 1 are gradually fitted together to form a near zero-clearance fit, ensuring the coaxiality of cutting and suturing;
[0059] Step 4: After the cutting knife 17 completes the foreskin cutting, the pushing sleeve 14 continues to advance, and the annular staple cartridge 15 releases the staples to complete the hemostatic suture;
[0060] Step 5: Reversely rotate the screw head 4 to withdraw the top body 16, remove the glans seat 1 and complete the operation.
[0061] During specific implementation, after the glans seat 1 is installed, the position of the pull rod 2 is adjusted and fixed by the locking sleeve 3, the screw head 4 is rotated to drive the top body 16 forward, the optical axis is gradually fitted, and cutting is performed. After the cutting knife 17 completes the cutting, the pushing sleeve 14 continues to advance and release the suture nail, and then the screw head 4 is rotated in the opposite direction to withdraw the top body 16, and the glans seat 1 is removed, which can shorten the operation time to within 3 minutes, minimize the patient's trauma, standardize the operation, and reduce the doctor's learning cost.
