Description

Technical Field

[0001] This invention relates to the field of circumcision staplers, and more specifically to a detachable clamp-type circumcision stapler. Background Technology

[0002] With the continuous development of medical technology, circumcision, as one of the most common surgeries of the male reproductive system, is constantly being improved and optimized in terms of treatment methods and surgical instruments. Traditional circumcision methods suffer from problems such as long operation time, significant trauma, and slow postoperative recovery, causing considerable pain and inconvenience to patients. Therefore, developing a new, efficient, and minimally invasive circumcision surgical instrument has become an important research direction in the current medical field.

[0003] While existing circumcision instruments can meet surgical needs to some extent, they still have some shortcomings. Among current technologies, the sleeve-type circumcision stapler has advantages in terms of effectiveness and portability, requiring only one application of force to achieve cutting and anastomosis. However, this stapler cannot observe the location of the foreskin corresponding to the cutting blade, demanding a very high level of surgical experience from the surgeon. Otherwise, incomplete cutting or blade jamming can easily occur, leading to tissue damage and bleeding, increasing the uncertainty of the surgery, the risk of postoperative complications, and the burden on medical staff. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention aims to provide a detachable clamp-type circumcision stapler to solve the problem that the circumcision stapler cannot observe the position of the foreskin corresponding to the cutting blade, which increases the uncertainty of the operation.

[0005] To address this, the present invention proposes a detachable clamp-type circumcision device, comprising an anastomosis semi-ring one, anastomosis semi-ring two, a clamping semi-ring one, a clamping semi-ring two, a cylindrical anvil, and a detachably connected handle assembly; the anastomosis semi-ring one and anastomosis semi-ring two are symmetrically distributed and each contains a semi-ring cutter, several anastomosis staples, and several wedge-shaped drive mechanisms; wherein, the anastomosis semi-ring one and the anastomosis semi-ring two rotate relative to each other through the handle assembly and are assembled into a complete circle, and then the semi-ring cutter completes the cutting process; the clamping semi-ring one and the clamping semi-ring two also rotate relative to each other through the handle assembly and are assembled into a complete circle; simultaneously, the clamping semi-ring one and the anastomosis semi-ring one rotate relative to each other through the handle assembly, driving the anastomosis semi-ring two and the clamping semi-ring two to rotate relative to each other, causing the wedge-shaped drive mechanisms in the anastomosis semi-ring one and the anastomosis semi-ring two to drive the anastomosis staples to move radially, completing the anastomosis staple bending and anastomosis process.

[0006] As a preferred embodiment of the present invention, both the first and second anastomotic semi-rings include a semi-ring body. The semi-ring cutter, a plurality of wedge-shaped drive mechanisms arranged in a ring array, and a plurality of anastomotic pins are all mounted on the semi-ring body, with the anastomotic pins located at the front end of the wedge-shaped drive mechanism. Each set of wedge-shaped drive mechanisms includes an axial wedge block and a radial wedge block. The semi-ring body is provided with a guide groove. The axial wedge block moves axially within the guide groove, and the axial wedge block drives the radial wedge block to move radially within the guide groove.

[0007] As a preferred embodiment of the present invention, the handle assembly includes a lower handle one, a lower handle two, an upper handle one, an upper handle two, and two semi-ring connecting pieces. The cross-section of the semi-ring connecting pieces is L-shaped. The first matching semi-ring is detachably connected to the first lower handle through the semi-ring connecting pieces, and the second lower handle is detachably connected to the second matching semi-ring through the semi-ring connecting pieces. The first upper handle is fixedly connected to the first tight semi-ring, and the second upper handle is fixedly connected to the second pressing semi-ring.

[0008] As a preferred embodiment of the present invention, the inner wall of the semi-ring connecting piece of the handle assembly is provided with a slot, Velcro or other quick-release structure, and the first matching semi-ring, the second matching semi-ring, the first pressing semi-ring and the second pressing semi-ring are also provided with buckles, Velcro or other quick-release structures.

[0009] As a preferred embodiment of the present invention, the lower handle one and the lower handle two are rotatably connected by a pin two, the upper handle one and the upper handle two are rotatably connected by a pin one, and the lower handle two and the upper handle two are rotatably connected by a horizontally extending pin three.

[0010] As a preferred embodiment of the present invention, the lower handle one, the lower handle two, the upper handle one, and the upper handle two are all of anisotropic integral structure, comprising, in sequence, a semi-circular connector, a straight section, an arc-shaped rotating section, and an arc-shaped gripping section; the semi-circular connector is fixedly connected to the corresponding semi-ring connecting piece or the clamping semi-ring; the straight section is provided with a pin hole one for installing pin one or pin two; the arc-shaped rotating section is provided with a pin hole two for installing pin three; and the arc-shaped gripping section is bent outward.

[0011] As a preferred embodiment of the present invention, the arc-shaped rotating segment connects the lower straight segment with the upper arc-shaped gripping segment to achieve an X-shaped cross connection similar to scissors, and the inner side of the arc-shaped rotating segment is provided with a clearance groove.

[0012] As a preferred embodiment of the present invention, the arc-shaped grip sections of the lower handle one and the lower handle two extend outwards in opposite directions; the arc-shaped grip sections of the upper handle one and the upper handle two also extend outwards in opposite directions; at the same time, the arc-shaped grip sections of the lower handle one and the upper handle one are projected to coincide in the vertical direction; the arc-shaped grip sections of the lower handle two and the upper handle two are projected to coincide in the vertical direction.

[0014] As a preferred embodiment of the present invention, the outer ring of the cylindrical anvil is provided with a cutting pad groove that cooperates with the semi-circular cutter and a plurality of bent nail grooves, and the bent nail grooves are distributed in a circular array.

[0015] The detachable clamp-type circumcision stapler provided by this invention adopts a clamp design. The surgeon only needs to align the clamp part of the stapler with the foreskin tissue to be anastomosed and then gently press to complete the anastomosis operation; this greatly simplifies the surgical procedure and reduces the difficulty of the surgeon's operation. Precise control technology is used during the anastomosis process to ensure accuracy and consistency. It can accurately anastomose the foreskin tissue, thus resulting in faster tissue healing after surgery and reducing postoperative recovery time. Furthermore, by reducing tissue damage and bleeding during the operation, the risk of postoperative complications such as infection is also reduced.

[0016] The clamp-type circumcision stapler, as a novel surgical instrument for circumcision, boasts advantages such as ease of operation, minimal trauma, and rapid recovery. Its emergence not only solves the problems and shortcomings of traditional surgical instruments but also improves surgical efficiency and quality, bringing patients a better treatment experience and outcomes. Therefore, the clamp-type circumcision stapler has broad market and application prospects. Furthermore, the first and second anastomotic rings are replaceable disposable products, and the handle assembly can be reused after sterilization, thereby reducing the overall cost of the circumcision stapler.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figures 1-6As shown, the detachable clamp-type circumcision device of the present invention includes: anastomosis half-ring 1, anastomosis half-ring 2, clamping half-ring 3, clamping half-ring 4, a cylindrical anvil 9, and a handle assembly; the anastomosis half-ring 1 and the anastomosis half-ring 2 are symmetrically distributed and each has a half-ring cutter 15, a plurality of anastomosis staples 14, and a plurality of wedge-shaped drive mechanisms inside; the handle assembly is used to drive the anastomosis half-ring 1 and the anastomosis half-ring 2 to rotate relative to each other and assemble into a complete circle, and to complete the cutting process through the half-ring cutter 15; the handle assembly is also used to drive the clamping half-ring 3 and the clamping half-ring 2 to rotate relative to each other and assemble into a complete circle; the handle assembly is also used to drive the clamping half-ring 3 and the anastomosis half-ring 1 to rotate relative to each other, and to drive the anastomosis half-ring 2 and the clamping half-ring 2 to rotate relative to each other, so that the wedge-shaped drive mechanisms inside the anastomosis half-ring 1 and the anastomosis half-ring 2 drive the anastomosis staples 14 to move radially, thereby completing the anastomosis staple process.

[0029] Specifically, such as Figure 4 , Figure 5 As shown, both the first anastomotic ring 1 and the second anastomotic ring 2 include a semi-ring body 11. A semi-ring cutter 15 is installed on the semi-ring body 11. Several wedge-shaped drive mechanisms and several anastomotic pins 14 are also installed on the semi-ring body 11. The anastomotic pins 14 are located on the front side of the end of the wedge-shaped drive mechanism. The wedge-shaped drive mechanisms are distributed in a ring array.

[0030] Each set of wedge-shaped drive mechanisms includes an axial wedge block 12 and a radial wedge block 13. A guide groove is provided on the semi-ring body 11. The axial wedge block 12 moves axially within the guide groove, driving the radial wedge block 13 to move radially within the guide groove. This further drives the anastomosis staple 14 to pierce the foreskin. The anastomosis staple 14 then engages with the bent staple groove 91 on the cylindrical anvil 9, bending the staple 14 to achieve the anastomosis purpose. Furthermore, rubber limiting pads 16 are installed on the upper end faces of the first and second anastomosis rings 1 and 2. The rubber limiting pads 16 have through holes, and the axial wedge block 12 has a limiting step. The rubber limiting pads 16 prevent the axial wedge block 12 from falling out of the guide groove.

[0031] like Figure 4 As shown, the cylindrical anvil 9 is a ring structure with a rectangular cross-section. The outer ring of the cylindrical anvil 9 is provided with several curved nail grooves 91, which are distributed in a ring array. The outer surface of the cylindrical anvil 9 is also provided with a cutting pad groove 92 that cooperates with the semi-circular cutter 15, so that the foreskin can be completely cut off during the cutting process of the semi-circular cutter 15.

[0032] like Figure 1 , Figure 6As shown, the handle assembly includes a lower handle 5, a lower handle 6, an upper handle 7, an upper handle 8, and two semi-ring connecting pieces 24. The cross-section of the semi-ring connecting piece 24 is L-shaped, which is used for detachable connection with the corresponding matching semi-ring and fixed connection with the corresponding handle. Specifically, the matching semi-ring 1 is detachably connected to the lower handle 5, the lower handle 6 is detachably connected to the matching semi-ring 2, the upper handle 7 is fixedly connected to the pressing semi-ring 3, and the upper handle 8 is fixedly connected to the pressing semi-ring 4.

[0033] The inner wall of the semi-ring connecting piece 24 is provided with a slot, Velcro or other quick-release structure, and the anastomotic semi-ring 1 and anastomotic semi-ring 2 are also provided with a buckle, Velcro or other quick-release structure. The handle assembly is a high-strength metal structure, and the anastomotic semi-ring 1 and anastomotic semi-ring 2 are replaceable disposable products; this allows the handle assembly to be sterilized and reused, thereby reducing the cost of the entire circumcision stapler.

[0034] Specifically, the lower handle 5 and the lower handle 6 are rotatably connected by the pin 22, so that the matching half ring 1 and the matching half ring 2 rotate relative to each other in the horizontal direction to achieve opening and closing. The upper handle 7 and the upper handle 8 are rotatably connected by the pin 21, so that the pressing half ring 3 and the pressing half ring 4 rotate relative to each other in the horizontal direction to achieve opening and closing. At the same time, the lower handle 6 and the upper handle 8 are rotatably connected by the horizontally extending pin 23, so that the matching half ring 2 and the pressing half ring 4 rotate relative to each other, thus completing the driving of the wedge-shaped drive mechanism on the matching half ring 2. The lower handle 5 and the upper handle 7 rotate relative to the lower handle 6 and the upper handle 8, respectively, thus also achieving the driving of the wedge-shaped drive mechanism on the matching half ring 1.

[0035] In addition, the lower handle 5, lower handle 6, upper handle 7, and upper handle 8 are all one-piece structures of different shapes, including a semi-circular connector 25, a straight section 26, an arc-shaped rotating section 27, and an arc-shaped grip section 28 in sequence; the semi-circular connector is fixedly connected to the corresponding semi-ring connecting piece 24, and the straight section is provided with a pin hole 1 for installing pin 1 21 and pin 2 22; the arc-shaped rotating section 27 of the lower handle 6 and the upper handle 8 is provided with a pin hole 2 for installing pin 3 23; the arc-shaped grip section is bent outward, and the outer side of the arc-shaped grip section 28 of the four handles is provided with an ergonomic wave-shaped anti-slip groove, which facilitates the doctor's operation and can apply sufficient force to complete the cutting and anastomosis procedures.

[0036] Furthermore, such as Figure 6As shown, the arc-shaped rotating section connects the lower straight section with the upper arc-shaped grip section, achieving an X-shaped cross connection similar to scissors. Furthermore, the inner side of the arc-shaped rotating section is provided with a clearance groove, which prevents interference between the handles during the rotation of the handle assembly. Specifically, the straight sections of the lower handle 1 5, lower handle 2 6, upper handle 1 7, and upper handle 2 8 are located on the fourth, third, first, and third layers, respectively; while the arc-shaped grip sections of the lower handle 1 5, lower handle 2 6, upper handle 1 7, and upper handle 2 8 are located on the second, first, third, and fourth layers, respectively.

[0037] Among them, the arc-shaped grip sections of the lower handle 1 5 and the lower handle 2 6 extend outwards in opposite directions; the arc-shaped grip sections of the upper handle 1 7 and the upper handle 2 8 also extend outwards in opposite directions; at the same time, the arc-shaped grip sections of the lower handle 1 5 and the upper handle 1 7 overlap in the vertical direction; the arc-shaped grip sections of the lower handle 2 6 and the upper handle 2 8 overlap in the vertical direction.

[0038] The special design of the above-mentioned handle assembly can not only realize the assembly of the first anastomosis ring 1 and the second anastomosis ring 2 into a complete circle to complete the cutting process, and the assembly of the first clamping ring 3 and the second clamping ring 4 into a complete circle, but also drive the relative rotation of the first clamping ring 3 and the first anastomosis ring 1, and the relative rotation of the second anastomosis ring 2 and the second clamping ring 4, so that the wedge-shaped drive mechanism inside the first anastomosis ring 1 and the second anastomosis ring 2 drives the anastomosis nail 14 to move, thus completing the anastomosis nail anastomosis process.

[0039] In this design, the bottom of the cylindrical anvil 9 is also provided with a limiting ring 93, and the limiting ring 93 is provided with a limiting boss 94. The first and second matching half rings 1 and 2 are respectively provided with grooves that match the limiting boss 94. Before the first and second matching half rings 1 and 2 are closed, the limiting ring 93 and the limiting boss 94 are used to limit the engagement with the cylindrical anvil 9, so that the bent nail groove 91 on the cylindrical anvil 9 matches the position of the matching nail 14 on the first and second matching half rings 1 and 2, thereby achieving accurate bending of the matching nail.

[0040] The working principle and process of the detachable clamp-type circumcision stapler of the present invention are briefly described below with reference to the accompanying drawings.

[0041] First, select a handle assembly of the appropriate size according to the patient's penis size, as well as a disposable stapler including a tubular anvil 9, anastomotic half-ring 1, and anastomotic half-ring 2; second, take the disposable tubular anvil 9 from the sterile packaging bag and place it over the foreskin of the penis, then fold the foreskin over the tubular anvil 9; take the disposable anastomotic half-ring 1 and anastomotic half-ring 2 from the sterile packaging bag, install them on the handle assembly, and fully unfold the handle assembly;

[0042] Then, the attending physician locates the foreskin cutting position, firmly grasps the lower handle 1 5 and lower handle 2 6 with one hand, closes the anastomotic half ring 1 and anastomotic half ring 2 and aligns them with the cylindrical anvil 9, the half ring cutter 15 on the anastomotic half ring 1 and anastomotic half ring 2 cooperates with the cutting pad groove 92 to cut off the excess foreskin; then the unfolded pressing half ring 1 3 and pressing half ring 2 4 are combined and put on the glans.

[0043] Finally, one hand holds the lower handle 26 and the upper handle 28 and presses down forcefully, while the other hand holds the lower handle 15 and the upper handle 17 and presses down forcefully, causing the wedge-shaped drive mechanism inside the anastomosis half-ring 1 and the anastomosis half-ring 2 to drive the anastomosis staple 14 to move radially; specifically, the pressing half-ring 13 and the pressing half-ring 24 drive the axial wedge block 12 to move axially in the guide groove, and the axial wedge block 12 then drives the radial wedge block 13 to move radially in the guide groove, further driving the anastomosis staple 14 to pierce the foreskin. Then the anastomosis staple 14 engages with the bent staple groove 91 on the cylindrical anvil 9, causing the anastomosis staple 14 to bend, completing the anastomosis staple anastomosis process.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
