Description

Technical Field

[0001] This utility model relates to the technical field of circumcision devices, and in particular to a cutting anastomosis device that can accurately preserve the length of the frenulum. Background Technology

[0002] Circumcision devices are widely used medical instruments in male circumcision surgery, and their technological background integrates innovative achievements in medical needs, materials science, and mechanical engineering. However, existing circumcision devices generally use a bell-shaped cover to fix the foreskin that is too long, then cut it with a blade, and finally suture it with staples. Traditional circumcision devices can result in different frenulum cutting lengths during the subsequent cutting process due to differences in the length of the foreskin of the patient. However, a frenulum that is too short can cause pain after penile erection, and in severe cases, require a second surgery for correction, which may lead to a need for a second operation. To address the above problems, this application provides a cutting stapler that can accurately preserve the length of the frenulum. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a cutting stapler that can precisely preserve the length of the frenulum, solving the technical problem that existing circumcision devices cannot select the length of the frenulum to be preserved based on the patient's individual condition, thus achieving the goal of preventing secondary foreskin tearing due to an excessively short frenulum.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cutting anastomosis device that can accurately preserve the length of the frenulum, comprising a supporting shell as a supporting base, an extension tube fixedly connected to one end of the supporting shell, a cutting inner shell slidably connected inside the supporting shell, extension grooves being provided at the top and bottom ends of the extension tube, a sliding screw sleeve being rotatably connected to the outside of the supporting shell, a mating screw sleeve being rotatably connected to the inside of the sliding screw sleeve, a fixing sleeve being fixedly connected in the middle of the mating screw sleeve, a staple seat being installed on the fixed sleeve near the end of the supporting shell, a plurality of mating slots being equidistantly provided on the outside of the staple seat, a cutting blade being fixedly connected to the end of the cutting inner shell near the fixing sleeve, a plurality of suture staple storage slots being provided on the cutting blade, and suture staples being placed inside the suture staple storage slots.

[0005] Preferably, the cutting blade is circular, and the diameter of the circle formed by the cutting edge of the cutting blade is larger than the diameter of the circularly arranged suture staples.

[0006] Preferably, in the horizontal state, the docking slot corresponds to the suture pin storage slot, and the extension length of the suture pin relative to the end of the cutting inner shell is greater than the extension length of the cutting blade relative to the end of the cutting inner shell.

[0007] Preferably, a limiting protrusion plate is fixedly connected inside the extension tube, and a pushing slider that is slidably connected inside the extension tube is fixedly connected to the end of the cutting inner shell. A return spring is connected between the pushing slider and the limiting protrusion plate.

[0008] Preferably, the top and bottom ends of the supporting shell are rotatably connected to pressing rods, and the middle sections of opposite ends of the pressing rods are rotatably connected to connecting rods.

[0009] Preferably, the connecting rods are all rotatably connected to the push slider at the end near the extension tube, and the connecting rods are all inclined towards the tail end of the extension tube.

[0010] By employing the above technical solution, this utility model provides a cutting stapler that can accurately preserve the length of the frenulum, and has at least the following beneficial effects: 1. Due to the novel suture and cutting structure, this utility model optimizes the design of the suture and cutting sequence, ensuring that the wound is completely sutured before cutting.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Current circumcision devices typically use a bell-shaped cover to fix the foreskin when it is too long, then cut it with a blade, and finally suture it with staples. Traditional circumcision devices can lead to variations in the length of the frenulum cut during the subsequent cutting process due to differences in foreskin length among patients. However, a too-short frenulum can cause pain after penile erection, and in severe cases, require further surgical correction, potentially resulting in a second surgery. Please refer to... Figures 1-4This embodiment provides a cutting stapler that can precisely preserve the length of the frenulum, solving the technical problem that existing circumcision staplers cannot select the length of the frenulum to be preserved according to the patient's own situation. The device includes a supporting shell 1 as a supporting base, an extension tube 2 fixedly connected to one end of the supporting shell 1, a cutting inner shell 3 slidably connected inside the supporting shell 1, extension grooves 4 at both the top and bottom of the extension tube 2, a sliding screw sleeve 5 rotatably connected to the outside of the supporting shell 1, a mating screw sleeve 6 rotatably connected to the inside of the sliding screw sleeve 5, a fixing sleeve 7 fixedly connected in the middle of the mating screw sleeve 6, a staple seat 8 installed near the end of the fixing sleeve 7 near the supporting shell 1, a plurality of mating slots 9 equidistantly opened on the outside of the staple seat 8, and a cutting blade 10 fixedly connected to the end of the cutting inner shell 3 near the fixing sleeve 7, a plurality of suture staple storage slots 11 opened on the cutting blade 10, and suture staples 12 placed inside the suture staple storage slots 11. The blade 10 is circular, and the diameter of the circle formed by the cutting blade 10 is larger than the diameter of the circularly arranged suture staples 12. Since the foreskin is everted during the operation, in order to ensure that the cutting blade 10 is outside the suture staples 12 and to prevent the cutting blade 10 from cutting off the foreskin sutured by the suture staples 12, the docking slot 9 corresponds to the suture staple storage slot 11 in the horizontal state. The extension length of the suture staples 12 relative to the end of the cutting inner shell 3 is greater than the extension length of the cutting blade 10 relative to the end of the cutting inner shell 3. In order to ensure that the suture staples 12 contact the foreskin first during cutting, so as to suture first and then cut, and to prevent the foreskin from shrinking due to the loss of restraint after cutting, resulting in incomplete suturing, a limiting protrusion plate 13 is fixedly connected inside the extension tube 2. A push slider 14 is fixedly connected to the end of the cutting inner shell 3 and slidably connected inside the extension tube 2. A return spring 15 is connected between the push slider 14 and the limiting protrusion plate 13.

[0017] To enable the cutting blade 10 to move and cut by pressing and clamping, a pressing rod 16 is rotatably connected to the top and bottom of the support shell 1. A connecting rod 17 is rotatably connected to the middle section of the opposite end of the pressing rod 16. The end of the connecting rod 17 near the extension tube 2 is rotatably connected to the push slider 14. The connecting rod 17 is inclined towards the tail end of the extension tube 2.

[0018] During the surgery, the operator places the fixing sleeve 7 on the outside of the patient's penis, then everts the foreskin and places it on the outside of the fixing sleeve 7. The everted foreskin is then secured to the outside of the fixing sleeve 7 with a frenulum. Next, the sliding screw sleeve 5 and the docking screw sleeve 6 are screwed together. The operator then presses the pressing rod 16, which pushes the connecting rod 17, which in turn rotates. The connecting rod 17 then moves the sliding slider 14, which in turn moves the cutting inner shell 3. During this movement, the sutures 12 inside the suture storage groove 11 at the end of the cutting inner shell 3 move to the docking slot on the suture seat 8 at the end of the fixing sleeve 7. Inside the groove 9, as the movement continues, the end of the suture staple 12 will pass through the foreskin and abut against the inner wall of the docking groove 9, thereby contracting and bending inward, and performing a circular suture on the foreskin fitted to the outside of the fixing sleeve 7. During this process, the extension length is less than that of the suture staple 12, and the already sutured foreskin will be cut when its end bends. As the movement continues, the cutting and suturing will be completed at the same time. During this process, the sliding screw sleeve 5 rotatably connected on the supporting shell 1 and the docking screw sleeve 6 fixedly connected on the fixing sleeve 7 can move stably according to the doctor's push, thereby adapting to patients with different penile lengths, facilitating subsequent surgery, and also providing calibration and fixation for the movement of the cutting inner shell 3 during the operation, avoiding deviations in the cutting.
