Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a hemorrhoid cutting forceps. Background Technology

[0002] Hemorrhoid surgery, also known as hemorrhoidectomy or hemorrhoid treatment surgery, is a medical procedure used to treat hemorrhoids (also called piles). Hemorrhoids are caused by abnormal dilation, varicose veins, and inflammation of the venous plexus around the anus. Different treatment methods can be chosen depending on the location and severity of the hemorrhoids.

[0003] Traditional anal surgery mainly includes two types: internal incision surgery, which involves limited resection inside the anus; and external incision surgery, which may cause postoperative stenosis. Traditional surgical methods typically use double-sleeve instruments, which have disadvantages such as limited operating space and a large diameter leading to postoperative pain and edema. In addition, although traditional longitudinal suturing surgery has good results, it is complex to perform and prone to problems such as bleeding and difficulty in suture removal.

[0004] Therefore, there is an urgent need to develop a hemorrhoid cutting forceps to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a hemorrhoid cutting forceps to solve the technical problem of limited surgical space and difficulty in achieving longitudinal suturing in existing technologies. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model provides a hemorrhoid cutting forceps, comprising:

[0008] A cylindrical body is used to open the patient's anus; the circumferential sidewall of the cylindrical body is provided with an incision for surgical cutting of the patient's internal hemorrhoids, and a clamping surface is provided on the side of the incision perpendicular to the axial direction of the cylindrical body.

[0009] Clamping component: detachably connected to the cylinder, the clamping component is provided with a pressing surface that corresponds to the clamping surface when the clamping component is installed on the cylinder, the pressing surface and the clamping surface cooperate to achieve a stable clamping of the hemorrhoids to be cut by the patient;

[0010] Fixing component: Fixedly installed at the tail end of the cylinder, used to limit and fix the clamping component, ensuring that the clamping component will not loosen or fall off during operation.

[0011] Furthermore, the clamping member includes:

[0012] Positioning rod: It is L-shaped and includes a connecting part and a fixing part that are perpendicularly connected to each other;

[0013] Clamping rod: Fixedly connected to the end of the connecting part away from the fixed part. The connecting part, the fixed part and the clamping rod are in the same plane. The extending direction of the clamping rod is opposite to the extending direction of the fixed part. The pressing surface is provided on the clamping rod for tight cooperation with the clamping surface on the cylinder.

[0014] Furthermore, both the extrusion surface and the clamping surface are provided with interlocking teeth. When the clamping rod and the cylinder work together to clamp the patient's hemorrhoids, the interlocking teeth can effectively clamp the hemorrhoid tissue.

[0015] Furthermore, the side wall of the cylinder near the clamping member is provided with multiple threading holes and multiple guide notches. The multiple threading holes are evenly arranged along the axial direction of the cylinder. The guide notches are opened from the side wall of the cut along the circumference of the cylinder and communicate with the corresponding threading holes. The threading holes are used for the circular needle to pass through and pass under the clamping rod through the patient's skin layer, then pass over the clamping rod and pass through each threading hole in sequence for suturing. Finally, the clamping rod is pulled out to achieve the suturing treatment of the incision.

[0016] Furthermore, the side wall of the cylinder near the clamping member is provided with multiple threading holes and multiple guide notches. The multiple threading holes are evenly arranged along the axial direction of the cylinder. The guide notches are opened from the side wall of the cut opening along the circumference of the cylinder and communicate with the corresponding threading holes. The clamping rod is provided with a guide hole. When the clamping rod is fixed to the cylinder, the guide hole and the threading hole are arranged opposite to each other. The threading hole is used for the circular needle to pass through and sew through the patient's skin layer through the guide hole.

[0017] Furthermore, the cylinder body is provided with a receiving groove, which is located on the side wall of the cut opening perpendicular to the axial direction of the cylinder body. The end of the clamping rod away from the connecting part is inserted into the receiving groove for positioning. The fixing part cooperates with the fixing member to fix the clamping member.

[0018] Furthermore, the fixing component includes a locking block fixedly installed at the tail end of the cylinder. The fixing part is connected to the connecting part at one end and has a locking groove. When the clamping rod is inserted into the receiving groove, the locking groove corresponds to the locking block, and the locking block is locked in the locking groove.

[0019] Furthermore, the clamping rod is made of a deformable material, and when not in use, the clamping rod is arc-shaped. When the clamping rod is inserted into the receiving groove and when the locking block is fixed, the clamping rod deforms from an arc-shaped rod to a straight rod.

[0020] Furthermore, multiple card blocks are provided, and the multiple card blocks are stacked and fixedly arranged. The card blocks are selected to be locked in the card slot at different positions according to the deformation of the clamping rod.

[0021] Furthermore, the cylinder body is also provided with an operating port for performing arterial ligation and suturing.

[0022] This invention provides a hemorrhoid cutting forceps, designed to address the problem of limited surgical space and difficulty in performing longitudinal suturing in existing technologies, thereby achieving stable clamping of hemorrhoids. This feature solves the problem of traditional methods being unable to perform longitudinal suturing, making longitudinal suturing surgery possible and further improving treatment outcomes.

[0023] Expanding the surgical operating space:

[0024] With its uniquely designed cylindrical structure, this hemorrhoid cutting forceps can effectively open the patient's anus, providing doctors with a wider field of vision and operating space. This not only helps improve the precision of the surgery but also reduces the risk of complications that may arise due to limited operating space.

[0025] Reduce postoperative pain and swelling:

[0026] The optimized tube diameter, smaller than traditional double-tube structures, reduces pressure on patient tissues, thus alleviating postoperative pain and edema. This design also makes the device more acceptable and improves patient comfort.

[0027] Achieving stable longitudinal suturing:

[0028] The incision is designed perpendicular to the axial direction of the cylinder, and a clamping surface is provided on one side of the incision. Combined with the compression surface on the detachable clamping component, this allows for stable clamping of hemorrhoids. This feature solves the problem of traditional methods' difficulty in performing longitudinal suturing, making longitudinal suturing surgery possible and further improving treatment outcomes.

[0029] Simplify surgical procedures and improve surgical efficiency:

[0030] The design of the fixation device ensures the stability and safety of the clamp throughout the surgical procedure, avoiding the risk of loosening or detachment. This design simplifies surgical steps, reduces surgical time and complexity, and improves the overall efficiency of the surgery.

[0031] Reduce the risk of bleeding:

[0032] Thanks to the robust clamping mechanism, the hemorrhoid tissue can be secured before cutting, reducing the likelihood of bleeding during the procedure. Furthermore, precise cutting and clamping help to better control bleeding points, thereby lowering the overall risk of bleeding.

[0033] Improving postoperative recovery:

[0034] With these improvements, especially in reducing postoperative pain, edema, and bleeding, patients' postoperative recovery speed is expected to be significantly improved. This not only shortens hospital stays but also reduces the probability of secondary surgery, providing patients with a better treatment experience.

[0035] In summary, the hemorrhoid cutting forceps of this invention, through its innovative structural design, effectively solves several problems existing in the prior art, providing a safer, more efficient, and more comfortable solution for hemorrhoid surgery. Attached Figure Description

[0045] The following is in conjunction with the appendix Figure 1-4 To further illustrate this application, an embodiment of this application discloses a hemorrhoid cutting forceps.

[0046] Example 1

[0047] Reference Figure 1 and Figure 2 As shown, a hemorrhoid cutting forceps includes a cylindrical body 100, a clamping member 200, and a fixing member 300. The cylindrical body 100 is generally cylindrical, with a conical cap-shaped design at its tip. This geometry not only facilitates smooth insertion of the instrument into the anus, reducing patient discomfort, but also effectively reduces the risk of damage to anal tissue during insertion. A spacious inner cavity is formed from the tail end to the head end of the cylindrical body 100, providing ample operating space for the surgeon. A cutting opening 120 is formed on the circumferential side wall of the cylindrical body 100, perpendicular to the axial direction of the cylindrical body 100, to accommodate the needs of longitudinal suturing surgery. The clamping member 200 is detachably connected to the cylindrical body 100 and positioned at the cutting opening 120 to clamp the skin at the area requiring cutting, reducing the need for additional fixation devices during cutting, simplifying the surgeon's operation, allowing for precise cutting under direct vision, and reducing the risk of misoperation. The fixing component 300 is fixedly installed at the tail end of the cylinder 100 to limit and fix the clamping component 200 installed on the cylinder 100. This ensures the stability of the clamping component 200 throughout the surgical procedure, preventing loosening or detachment and improving the safety and reliability of the surgery.

[0048] Reference Figure 1 and Figure 3 As shown, the clamping member 200 includes a positioning rod and a clamping rod 210. The positioning rod is L-shaped, meaning it includes a fixing part 230 and a connecting part 220 that are perpendicularly connected to each other. The clamping rod 210 is I-shaped and is fixedly connected to the end of the connecting part 220 away from the fixing part 230. The length extension directions of the clamping rod 210, the fixing part 230, and the connecting part 220 are all in the same plane, and the fixing part 230 and the clamping rod 210 are located on opposite sides of the connecting part 220 and extend in opposite directions. That is, the clamping member 200 is "similar" to a Z-shape.

[0049] The cylinder 100 is provided with a receiving groove 130 for inserting the clamping member 200. The receiving groove 130 is located on the side wall of the cut opening 120 perpendicular to the axial direction of the cylinder 100, and the receiving groove 130 is close to the circumferential side wall of the receiving groove 130, that is, the receiving groove 130 is opened at the corner of the cut opening 120.

[0050] When surgery is required, the cylinder 100 is inserted into the patient's anus, and the hemorrhoid to be cut protrudes from the incision 120. The end of the clamping rod 210 away from the connecting part 220 is inserted into the receiving groove 130, and the side wall of the clamping rod 210 is pushed closer to the side wall of the receiving groove 130 in the circumferential direction to squeeze the hemorrhoid between the side wall of the receiving groove 130 and the side wall of the clamping rod 210 to achieve clamping and fixation. The clamping member 200 is fixed by the fixing member 300, thereby completing the surgical cutting and subsequent surgical suturing operation.

[0051] The clamping rod 210 has a compression surface on its side wall for clamping the tissue to be cut, and the receiving groove 130 has a clamping surface on its side wall that cooperates with the compression surface. Both the compression surface and the clamping surface are provided with interlocking teeth 170. When the clamping rod 210 cooperates with the cylinder 100 to clamp the patient's hemorrhoids, the interlocking teeth 170 can effectively clamp the hemorrhoid tissue.

[0052] The increased friction between the clamping rod 210, the receiving groove 130 and the patient tissue not only helps to keep the clamping rod 210 in a fixed position, but also effectively resists the action of external forces, ensuring the reliability of clamping.

[0053] The clamping rod 210 is preferably made of a deformable material (such as a medical-grade elastic alloy or polymer material) with excellent elasticity and memory properties. This material can deform when an external force is applied and quickly return to its original shape after the external force is removed. The main purpose of selecting such a material is to ensure that the clamping rod 210 maintains good performance under different conditions, while reducing damage to patient tissues.

[0054] When not in use, the clamping rod 210 is set in a natural arc shape. When the clamping rod 210 is inserted into the receiving groove 130, its squeezing surface contacts the patient's tissue, thereby forcing the clamping rod 210 to gradually straighten under the action of external force and reach the fixed position of the fixing member 300, thus completing the fixation of the clamping rod 210 and improving the clamping effect.

[0055] Reference Figure 1 and Figure 3 As shown, the fixing member 300 includes a plurality of locking blocks 310 fixedly installed at the tail end of the cylinder 100. The plurality of locking blocks 310 are arranged in a stepped manner along the radial extension direction of the cylinder 100. The fixing part 230 is connected to the connecting part 220 at one end and has a locking groove 240 for the locking blocks 310 to cooperate with each other to fix the clamping member 200.

[0056] When it is necessary to perform internal hemorrhoid surgery on the patient, the end of the clamping rod 210 away from the connecting part 220 is inserted into the receiving groove 130, and the side wall of the clamping rod 210 is pushed closer to the side wall of the receiving groove 130 in the circumferential direction, so as to squeeze the hemorrhoid between the side wall of the receiving groove 130 and the side wall of the clamping rod 210 to achieve clamping and fixation. Different locking blocks 310 are selected and locked into the locking groove 240 according to the clamping situation to achieve multi-level adjustment and fixation.

[0057] With multiple clamping blocks 310 arranged in a stepped manner along the radial extension direction, doctors can select clamping blocks 310 of different heights to cooperate with the clamping slots 240 according to the specific situation of hemorrhoids. This design not only provides a variety of clamping forces to choose from, but also allows for flexible adjustment of the clamping force, avoiding excessive clamping that could cause tissue damage, or insufficient clamping that could lead to insecure fixation.

[0058] Reference Figure 1 and Figure 2 As shown, the side wall of the cylinder 100 near the clamping member 200 has multiple threading holes 140 and multiple corresponding guide notches 150. The multiple threading holes 140 are evenly arranged along the axial direction of the cylinder 100, ensuring the consistency and stability of the suture path during suturing. This design allows the doctor to maintain a uniform stitch spacing during suturing, avoiding poor suturing results caused by uneven stitch spacing. The guide notches 150 extend from the clamping surface along the circumferential direction of the cylinder 100 and connect to the threading holes 140, providing a clear guide path for the suture. This not only simplifies the suturing operation but also ensures that the suture can fit tightly against the clamping rod 210, reducing the loosening or tangling of the suture during suturing.

[0059] During suturing, the circular needle first passes through a suture hole 140, then around the patient's skin layer, passes under the clamping bar 210, then passes over the clamping bar 210, and finally enters the next suture hole 140 for suturing. This method of using the circular needle simplifies the suturing operation and reduces the difficulty for the surgeon, especially in complex or delicate surgeries.

[0060] After suturing is completed, the doctor can easily remove the clamping rod 210. The whole process is simple and quick, and will not affect the completed suture. The removal design of the clamping rod 210 not only simplifies the postoperative cleaning work, but also ensures a clean and safe surgical environment.

[0061] Reference Figure 1 and Figure 2 As shown, the cylindrical body 100 also has an operating port 160 for performing arterial ligation and suturing. A fixing plate 110 extending radially along the tail end of the cylindrical body 100 is also fixedly connected. These two fixing plates 110 conform to the patient's buttocks during use, ensuring the cylindrical body 100 remains stable and does not shift during surgery. This design is particularly suitable for surgeries requiring prolonged operation, such as arterial ligation and suturing, effectively preventing the cylindrical body 100 from slipping and ensuring the smooth progress of the surgery.

[0062] Example 2

[0063] The difference between this embodiment and Embodiment 1 lies in the structure of the clamping rod 210.

[0064] Reference Figure 4 As shown, specifically, the clamping rod 210 has multiple guide holes 250, which are positioned opposite to the threading holes 140 when the clamping rod 210 is fixed to the cylinder 100. The guide holes are notches on the side wall of the clamping rod for the suture to pass through. This design allows the circular needle to pass directly through the threading hole 140, around the patient's skin layer, through the guide hole 250, and finally into the next threading hole 140 for suturing. This use of the circular needle not only simplifies the suturing operation but also avoids the step of removing the clamping rod 210 in traditional designs, ensuring a close fit between the suture and the skin and improving the suturing effect.

[0065] The guide hole 250 is designed to allow the circular needle to pass smoothly through multiple anchor points during suturing, enhancing suture stability. This not only improves suture strength but also reduces the risk of suture loosening or slippage, ensuring consistent and reliable suturing results. Since the clamping rod 210 does not need to be withdrawn after suturing, the surgeon can complete high-quality suturing in a shorter time, reducing surgical time and patient discomfort. Furthermore, simplified operation reduces the surgeon's workload, indirectly improving surgical efficiency.

[0066] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
