Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a subcutaneous tumor dissector. Background Technology
[0002] Subcutaneous cystectomy is a common and routine treatment in dermatological surgery to remove benign subcutaneous masses such as epidermal cysts and lipomas. The core objective of the surgery is to precisely and safely dissect the cyst, avoiding damage to surrounding healthy tissue, especially the skin, blood vessels, and nerves, while minimizing postoperative complications such as bleeding and infection. With the development of minimally invasive techniques, surgical procedures are becoming increasingly refined and personalized, especially in dermatological surgery, where the design and application of instruments play a crucial role in surgical outcomes.
[0003] Currently, commonly used surgical instruments for dissection, including forceps, scissors, and suction devices, can perform subcutaneous cyst dissection, but some technical limitations remain. Existing dissection tools generally suffer from insufficient precision, difficulty in accurately controlling force, and a tendency to damage surrounding healthy tissue, leading to more difficult and time-consuming surgeries. These shortcomings are particularly pronounced when dealing with smaller, deeper, or more complex cysts.
[0004] Therefore, designing a pair of scissors specifically for subcutaneous cyst dissection in dermatological surgery would not only provide greater operational precision but also improve surgical efficiency and patient recovery quality while ensuring surgical safety. This is a pressing issue in the field of dermatological surgery. Utility Model Content
[0005] This utility model is proposed to alleviate or solve at least one aspect or point of the above-mentioned problems.
[0006] To address the shortcomings of the existing technology, a subcutaneous tumor dissector is provided, comprising a forceps body, which is composed of a hinged first forceps body and a second forceps body. One side of the forceps body is a head section, and the other side is a forceps arm section. The forceps arm section includes a gripping part and a forceps arm. The gripping part is located at the end away from the head section, and the forceps arm connects the gripping part and the head section. The head section includes a transition part and a dissector part. The transition part connects the forceps arm section and the head section respectively, and the dissector part is located at the end away from the forceps arm section. The dissector part has an arc-shaped structure with a radius between 5-20 mm. The plane containing the center line of the dissector part is perpendicular to the plane containing the transition part. The cross-section of the dissector part gradually narrows from the transition part towards the end of the dissector part. The dissector part includes a first dissector part and a second dissector part, with the first dissector part disposed on the first forceps body and the second dissector part disposed on the second forceps body.
[0007] The first clamp body is provided with an elastic component to assist the first clamp body and the second clamp body in moving between a first position and a second position.
[0008] In the first position, the first and second clamping bodies are in a closed state, the first and second peeling portions are closed, and the elastic member is in a compressed state.
[0009] In the second position, the first clamp and the second clamp are separated, the first peeling part and the second peeling part are separated, and the elastic component is not under pressure.
[0010] Preferably, the angle between the peeling portion and the transition portion is in the range of 20-90 degrees.
[0011] Preferably, a blunt cutting edge is formed at the edge of the peeled portion.
[0012] Preferably, the first peeling portion is provided with a first protrusion, and the second peeling portion is provided with a second protrusion.
[0013] Preferably, the cross-section of the peeled portion gradually transitions from a rectangle to an ellipse.
[0014] Preferably, when the first clamp and the second clamp are in the closed state, the first peeling part and the second peeling part abut against each other and are symmetrically distributed from left to right.
[0015] Preferably, when the first clamp and the second clamp are in the closed state, the first peeling part and the second peeling part abut against each other and are distributed vertically.
[0016] Preferably, the gripping part is provided with a hole of circular or partially circular structure.
[0017] Preferably, the elastic component is disposed on the head section side.
[0018] Preferably, the elastic component is disposed on the side of the clamp arm section.
[0019] This invention, with its precise dissection function, significantly improves the effectiveness of dermatological cyst removal surgery, mainly in the following aspects:
[0020] Improve surgical precision:
[0021] The blunt blade of this subcutaneous tumor dissector allows for easy cutting of the cyst's outer membrane without damaging surrounding healthy tissue. Its precise dissection function ensures surgeons can accurately separate the cyst from surrounding structures without harming the skin and adipose tissue, avoiding accidental damage to blood vessels and nerves. Optimized scissor angle and sharpness result in smoother cutting, effectively reducing intraoperative injuries.
[0022] Reduce bleeding and tissue damage:
[0023] The head of the subcutaneous tumor dissector is designed in a dissector mode, allowing for blunt dissection without damaging surrounding blood vessels and protecting the cyst wall from puncture and contamination of the surgical incision, thus making the surgery safer and reducing the incidence of postoperative complications.
[0024] Improve operating comfort and stability:
[0025] Featuring an ergonomically designed grip, the scissors' grip, with its optimized angle and materials, provides greater comfort and a stable operating posture for the operator. The elasticity of the flexible components accelerates dissection, and the curved dissection section allows for deeper penetration into the tumor's base, significantly improving surgical efficiency and precision.
[0026] Highly adaptable, suitable for surgical treatment of tumors of different sizes:
[0027] The dissection section of this subcutaneous tumor dissector is designed with flexibility, available in different sizes to accommodate cysts of varying depths and sizes. Whether the subcutaneous cyst is superficial or deep, the dissection section can be easily manipulated. The design considers not only the handling of small cysts but also the dissection of deep and complex cysts, providing greater operational adaptability.
[0028] Improved cost-effectiveness:
[0029] Through its innovative design, this patent not only improves surgical outcomes but also effectively reduces the complexity and time required during the procedure, minimizing the consumption of surgical time and medical resources, thus demonstrating high cost-effectiveness. Furthermore, its high durability helps hospitals save on equipment procurement and maintenance costs over the long term. Attached Figure Description

[0044] To enable those skilled in the art to utilize the present invention, the following exemplary embodiments may be provided in conjunction with specific application scenarios, specific systems, device and component parameters, and specific connection methods. However, these embodiments are merely examples for those skilled in the art, and the general principles defined herein can be applied to other embodiments and application scenarios without departing from the spirit and scope of the present invention.
[0045] According to an exemplary embodiment of the present invention: Figures 1-5 As shown, a subcutaneous tumor dissector includes a forceps body, which consists of a first forceps body 1 and a second forceps body 2 hinged together. One side of the forceps body is a head segment 3, and the other side is a forceps arm segment 4. The forceps arm segment 4 includes a gripping part 41 and a forceps arm 42. The gripping part 41 is located at the end away from the head segment 3. Exemplarily, the gripping part 41 has a circular hole. In use, the operator passes one finger through the circular hole in the gripping part 41 and, with the assistance of other fingers, grips the gripping part 41. This ergonomic design makes the surgeon more comfortable during operation and allows them to maintain a stable operating posture. The forceps arm 42 connects the gripping part 41 and the head segment 3. The length of the forceps arm 42 is adjustable to meet the needs of different departments, such as laparoscopic surgery in obstetrics and gynecology, where a longer forceps arm 42 is required. The head segment 3 includes a transition section 31 and a dissection section 32. The transition section 31 connects the clamp arm segment 4 and the head segment 3, respectively. The dissection section 32 is located at the end away from the clamp arm segment 32. The dissection section 32 has an arc-shaped structure with a radius between 5-20 mm, which can accommodate cysts of different depths and sizes. Preferably, the radius of the arc is 10 mm. The plane containing the center line of the dissection section 32 is perpendicular to the plane containing the transition section 31. The angle between the dissection section 32 and the transition section 31 is between 20-90 degrees. Whether it is a superficial or deep subcutaneous cyst, the dissection section 32 can be easily operated, allowing the operator to easily dissect the subcutaneous mass, greatly improving the efficiency and accuracy of the surgery. Preferably, the angle between the dissection section 32 and the transition section 31 is 45 degrees. The edge of the dissection section 32 forms a blunt blade. When the first clamp body 1 and the second clamp body 2 separate, the blunt blade structure at the edge of the dissection section 32 can easily cut the outer membrane of the cyst without damaging the surrounding healthy tissue.
[0046] The cross-section of the peeling portion 32 gradually narrows from the transition portion 31 toward the end of the peeling portion 32. For example, the cross-section of the peeling portion 32 gradually transitions from a rectangle to an ellipse, forming a structure that is thick in the middle and thin at the edges. A blunt blade structure is formed at the edges, which can easily cut the outer membrane of the cyst without damaging the surrounding healthy tissue, facilitating peeling deep into the bottom of the cyst.
[0047] The dissection section 32 includes a first dissection section 33 and a second dissection section 34. The first dissection section 33 is disposed on the first clamp body 1 and has a first protrusion 35. The second dissection section 34 is disposed on the second clamp body 2 and has a second protrusion 36. When the first clamp body 1 and the second clamp body 2 are in the closed state, the first dissection section 33 and the second dissection section 34 abut against each other and are symmetrically distributed to form the dissection section 32. The first protrusion 35 and the second protrusion 36 abut against each other to form an elliptical upward protrusion. The protrusion structure makes the tip of the dissection section 32 not sharp, forming a blunt blade structure. When the dissection section 32 enters the cyst through the gap of the cyst, it is not easy to damage the surrounding tissue and cyst wall and cause incision contamination.
[0048] The first clamp body 1 is provided with an elastic component 11. For example, the elastic component 11 is a spring or a spring sheet, which is provided on the side wall of the clamp arm section 4. Utilizing its own elasticity, the first clamp body 1 and the second clamp body 2 rotate relative to the hinge part, switching from the first position to the second position, providing assistance. The operator's general habit is to hold the clamp body, so that the first clamp body 1 and the second clamp body 2 are in a closed state. However, when peeling the cyst, the operator needs to use force to separate the first clamp body 1 and the second clamp body 2, which is not easy to do. Utilizing the elastic force of the elastic component 11 can speed up the peeling speed.
[0049] In the first position, the first clamp 1 and the second clamp 2 are in a closed state, the first peeling part 33 and the second peeling part 34 are in a closed state, and the elastic member 11 is in a compressed state.
[0050] In the second position, the first clamp 1 and the second clamp 2 are separated, the first peeling part 33 and the second peeling part 34 are separated, and the elastic member 11 is not under pressure.
[0051] According to an exemplary embodiment two of the present invention: Figure 6 As shown, a subcutaneous tumor dissector differs from Exemplary Example 1 in that the elastic member 11 is disposed on the sidewall of the head segment 3.
[0052] According to Exemplary Example 3 of this utility model: Figures 7-8As shown, a subcutaneous tumor dissector differs from Exemplary Example 1 in that the gripping part 41 has a semi-circular hole. In use, the operator's five fingers pass through the circular hole in the gripping part 41 to grasp it; the length of the clamp arm 42 is shortened.
[0053] When the first clamp 1 and the second clamp 2 are in the closed state, the first peeling part 33 and the second peeling part 34 abut against each other and are distributed vertically.
[0054] Working principle:
[0055] First, the operator grips the gripping part 41 firmly. When the gripping force exceeds the elastic force of the elastic component 11, the first clamp body 1 and the second clamp body 2 are in a closed state. At this time, the elastic component 11 is under pressure, and the first peeling part 33 and the second peeling part 34 are in a closed state, forming the peeling part 32. The operator controls the force so that the peeling part 32 enters the cyst through the gap. The arc shape of the peeling part 32 makes it easy for the peeling part 32 to enter the bottom of the cyst. The first protrusion 35 and the second protrusion 36 abut against each other to form an elliptical upward protrusion. The blunt blade structure makes it less likely to damage surrounding tissues and cyst walls, thus preventing incision contamination. Secondly, when performing cyst dissection, the operator must control the forceps to rotate the first forceps 1 and the second forceps 2 relative to each other at the hinge, moving them from the first position to the second position. This separates the first dissection part 33 and the second dissection part 34. The elastic force of the elastic component 11 itself provides assistance for the rotation of the first forceps 1 and the second forceps 2 relative to each other at the hinge. At the same time, the blunt blade structure at the edge of the dissection part 32 performs the cyst dissection operation.
[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations and combinations of elements may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
