Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an endoscopic resection channel device for frontal bone osteoma. Background Technology

[0002] Frontal osteoma resection is a surgical procedure for benign bone tumors in the frontal bone. Its main purpose is to relieve pressure on surrounding tissues (such as brain tissue, nerves, or blood vessels) or to improve appearance. The surgery is usually performed under general anesthesia. After determining the tumor's extent using imaging techniques (such as CT or 3D reconstruction), a craniotomy or endoscopic approach is chosen. Tools such as bone chisels and drills are used to precisely remove the diseased bone tissue while protecting adjacent structures. Postoperative care includes infection prevention, monitoring for bleeding risk, and follow-up imaging to confirm the resection's effectiveness. The incision site for frontal osteoma resection is usually a straight incision along the surface projection of the lesion area. Although this provides sufficient exposure of the surgical field and a convenient operating path, the linear scar formed after healing is easily noticeable in the aesthetically sensitive area of ​​the face. To optimize the postoperative appearance, the current practice is to use the scalp flap position inside the hairline as a concealed incision, combined with endoscopic instruments for precise resection of the osteoma. However, compared to a straight incision, a concealed incision located further back presents challenges in terms of instrument operation due to the relatively small surgical field and confined space. To ensure surgical safety and reduce the difficulty of resection, the current practice is to insert and cover the osteoma resection area using a self-made semi-circular cross-section tube, such as a sterile plastic tube, to provide the surgeon with operating space. However, it is difficult to guarantee the regularity of the cut surface of the self-made tube, and the depth of insertion and placement, as well as the construction of the mid-band vision, still require manual lifting of the external end of the tube. All of these operations are risky, and there is a lack of a targeted channel device to meet the needs of use during surgery. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing channel structure for resecting frontal osteoma has safety risks during use. In view of the problems of the existing technology, an endoscopic resection channel device for frontal osteoma is provided.

[0004] The purpose and effect of this utility model are achieved by the following specific technical means: including a channel tube, wherein the channel tube is a medical transparent plastic tube with a semi-circular open end, and the two ends of the channel tube extend to form a tube head and an outer tube part respectively; The lower edge of the outer tube is fitted with matching support frames on both sides, and the support frames extend to both sides of the channel tube edge to form support rods. The end of the support rod is slidably provided with a gear shaft between it and the edge of the channel tube wall, and the gear shaft is hinged to the support rod. An inner ring is provided between the two support rods on both sides, which slides and matches the channel tube wall, and the inner ring is hinged to the support rod through the gear shaft. The support frames on both sides extend to form a corner wheel seat at one end near the outer tube. A hinge arm with a shearing and folding shape is fixed between the inner end of the corner wheel seat and the channel tube. A curved frame is fixed between the outer side of one corner wheel seat and the channel tube. A transmission gear is axially arranged between the inner side of the corner wheel seat and the curved frame. A toothed groove that meshes with the transmission gear is arranged in a ring on the inner side of the curved frame, so that the support frame can arch the channel tube along the end of the support rod and with the corner wheel seat as the fulcrum.

[0005] A further preferred embodiment: the channel tube has a toothed groove on the connection end with the gear shaft that matches the surface of the gear shaft, and the toothed groove rolls into contact with the gear shaft.

[0006] A further preferred embodiment: the head end of the tube has an angled cut surface, and the angle of the cut surface of the tube head matches the arching angle of the support frame.

[0007] A further preferred embodiment: the outer tube extends to form a plate on both sides, and the plate has an adhesive portion for attaching medical tape at both ends.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figures 1-5 The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.

[0015] An endoscopic resection channel device for frontal bone osteoma includes a channel tube 1, which is a medical transparent plastic tube with a semi-circular open end, and the two ends of the channel tube 1 extend to form a tube head 2 and an outer tube part 3, respectively. The lower edge of the outer tube 3 is fitted with matching support frames 6 on both sides, and the support frames 6 extend to both sides of the edge of the channel tube 1 to form support rods 9. The end of the support rod 9 is slidably provided with a toothed shaft 10 between the end of the support rod and the edge of the wall of the channel tube 1, and the toothed shaft 10 is hinged to the support rod 9. An inner ring 11 is provided between the two support rods 9 and slides to match the wall of the channel tube 1, and the inner ring 11 is hinged to the support rod 9 through the toothed shaft 10. The two side support frames 6 extend to form a corner wheel seat 7 at one end near the outer tube 3, and a hinge arm 12 in a shearing and folding shape is fixed between the inner end of the corner wheel seat 7 and the channel tube 1. A curved frame 8 is fixed between the outer side of one corner wheel seat 7 and the channel tube 1. A transmission gear 14 is axially arranged between the inner side of the corner wheel seat 7 and the curved frame 8, and a tooth groove that meshes with the transmission gear 14 is arranged in a ring on the inner side of the curved frame 8, so that the support frame 6 can arch the channel tube 1 along the end of the support rod 9 and with the corner wheel seat 7 as the fulcrum. This type of endoscopic resection device for frontal bone osteoma comprises a semi-circular open medical transparent plastic tube 1. The semi-circular open surface serves as the contact end for the tube to extend into the covered area. The semi-circular tube wall supports the entire skin incision area. The operating area is primarily the space within the tube 1. The tube head 2 at the front end serves as the insertion end, and the outer tube 3 at the rear end serves as the contact end between the tube 1 and the patient's frontal bone skin. During operation, the tube head 2 is inserted along the frontal bone skin incision into the osteoma location area until the tube 1 reaches the coverage area of ​​the osteoma. The transmission gear 14 can be rotated to cause it to mesh and roll relative to the outer curved frame 8. Because the outer tube 3 is relatively... The transmission gear 14 is fixed so that when it moves along the curved frame 8, the corresponding angle wheel seat 7 will support the entire channel tube 1 along the curved frame 8. With the angle wheel seat 7 as the fulcrum, the corresponding folded hinge arm 12 matches the movement of the angle wheel seat 7 and the channel tube 1. The hinge arm 12 assists in supporting the channel tube 1. During the entire support process, the end of the support rod 9 will be hinged to the connected gear shaft 10 to adapt to the relative inner angle between the angle wheel seat 7 and the channel tube 1. Simultaneously, the inner ring 11 connects the two side support rods 9 and the angle wheel seat 7 to maintain the consistency of the position of the left and right side support rods 9 of the channel tube 1, thus completing the support of the channel tube 1. This allows the surgeon to complete a series of operations during the operation through the surgical operation area constructed by the support of the channel tube 1. Based on the above, the channel tube 1 has a toothed groove on the connection end with the toothed shaft 10 that matches the surface of the toothed shaft 10, and the toothed groove and the toothed shaft 10 roll into each other. In the channel tube 1, the relative position of the angle wheel seat 7 and the channel tube 1 can be adjusted in advance according to the distance of the insertion position, that is, the fulcrum position of the angle wheel seat 7 is adjusted. Specifically, before inserting the channel tube 1, the support rod 9 is stretched axially along the edge of the channel tube 1, so that the support rod 9 drives the toothed shaft 10 to roll and translate relative to each other along the connection part of the channel tube 1. The toothed groove tooth pattern specification is used to limit the rolling accuracy under the corresponding rolling stroke, which makes it convenient for doctors to determine the support angle position of the channel tube 1 according to the actual situation, thus improving the applicability of the device. This channel device provides effective support for the entire surgical procedure through an adjustable and supported tube structure. The front and rear edges of the channel tube 1 are smoothed, and the folded structure of the channel tube 1, along with the corner wheel seat 7 and support rod 9, during insertion can maintain a relatively small insertion end, which is convenient for surgeons to locate the osteoma area. This provides flexibility for the insertion of the entire device and, together with subsequent adjustment and support arching operations, provides effective support for the construction of the surgical field. Moreover, the fulcrum position is relatively outward, avoiding the operational risks of supporting the tube structure from the inside, thus improving the safety and practicality of the device. The tube head 2 has an angled cut surface at its end, and the angle of the cut surface of the tube head 2 matches the arching angle of the support frame 6, such as... Figure 2 , 3 As shown, the tube body of the channel tube 1 after being supported and arched will be relatively tilted, and the corresponding tube head 2 will be more in-between than the horizontal position when inserted, so as to avoid the horizontally set tube head 2 from contacting the frontal bone surface, or from forming a clamping action with the frontal bone surface during the arching process to damage the edge tissue of the frontal bone, thus affecting the support of the entire channel tube 1 and improving the safety of the device. Based on the above, the outer tube 3 extends to both sides to form a patch 5, and the patch 5 has adhesive portions for attaching medical tape at both ends, such as... Figure 1 As shown, after the channel tube 1 is inserted and fixed in position, the surgeon can use tape to adhere and fix the edge plate 5 of the outer tube 3 to the skin preparation area of ​​the patient's frontal bone, so as to maintain the position of the entire outer tube 3 of the channel tube 1 and improve the stability of the device. Furthermore, a shaft tube 13 fixed to the angular wheel seat 7 is provided at the outer end of the transmission gear 14. A rubber tube extends from the outer end of the shaft tube 13, and an adjusting handle 4 is fixed at the end of the rubber tube. An adjusting wheel 15 that can be rotated and adjusted is embedded in the adjusting handle 4. A toothed chain 16 is engaged with the transmission gear 14 at the inner rotating end of the adjusting wheel 15. The toothed chain 16 is arranged in the rubber tube. This device involves adjusting the transmission gear 14, which is specifically achieved by the adjusting handle 4. The surgeon can hold the adjusting handle 4 and roll it with his fingers. The adjustment wheel 15 is used to drive the toothed chain 16 and the transmission gear 14 connected to the end through the rotation of the adjustment wheel 15, so as to realize the adjustment of the arching movement of the transmission gear 14 and the entire corner wheel seat 7. By setting the meshing specifications of the transmission tooth 14, toothed chain 16 and adjustment wheel 15 of the corresponding specifications, the rotation stroke of the adjustment wheel 15 and the arching movement stroke of the corner wheel seat 7 are refined, thereby improving the displacement accuracy of the entire channel tube 1 and corner wheel seat 7 and facilitating fine adjustment operation. The rubber tube connected to it provides flexibility for the position of the adjustment handle 4. Furthermore, both the shaft tube 13 and the adjusting handle 4 have arc-shaped limiting parts protruding at the ends connected to the hose. To ensure that the toothed chain 16 is not affected by the bending of the hose, both ends of the toothed chain 16 are limited by the limiting parts of the shaft tube 13 and the adjusting handle 4 to maintain the tension at both ends of the toothed chain 16 and ensure the reliability of the transmission structure of the toothed chain 16.
