Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a flat-head scraper for laparoscopy. Background Technology

[0002] The urological scraper is known to integrate electrocoagulation, electrocautery, dissection, scraping, and suction functions. It can remove smoke and blood during surgery in real time and maintain a clear surgical field. As an accessory to high-frequency surgical equipment, it is used in conjunction with the equipment and is sometimes used during surgery to cut, ablate, coagulate, and dissect human tissue. It is a widely used electrosurgical consumable in urological surgery. In urology, it is often used in surgeries on the prostate and bladder to help doctors complete surgical procedures more precisely and efficiently.

[0003] However, in actual use, when removing renal angiomyolipoma, the basal fat and smooth muscle tissue is not easily removed with a regular round-headed suction device, and it is necessary to cut the basal tissue with scissors, which can easily lead to bleeding. In addition, the commonly used laparoscopic suction device has a rounded tip, which can only perform blunt suction and cannot completely remove tissue surfaces with rough surfaces, leading to postoperative infection. Therefore, a flat-headed scraper for laparoscopy is proposed as a further improvement. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a flat-head scraper for laparoscopy to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flat-headed scraper for laparoscopy, comprising: a scraper head and a rod body, the scraper head being fixedly connected to one end of the rod body, the rod body having a suction channel extending through both ends, the scraper head having a high-efficiency suction cavity communicating with the suction channel, a suction tube installed at the end of the rod body away from the scraper head communicating with the suction channel, the scraper head being flat in shape, the width of the scraper head not less than the diameter of the rod body, the thickness of the scraper head not greater than the diameter of the rod body, and the rod body being cylindrical in shape.

[0006] Furthermore, the high-efficiency suction cavity includes a wide scraping suction cavity, the wide scraping suction cavity being configured to be flat.

[0007] Furthermore, the high-efficiency suction cavity includes a narrow scraping suction cavity, the narrow scraping suction cavity being flat in shape, and the cross-sectional area of ​​the narrow scraping suction cavity being no greater than the cross-sectional area of ​​the suction channel.

[0008] Furthermore, the high-efficiency suction cavity includes: a first suction cavity and a second suction cavity, one end of the first suction cavity and one end of the second suction cavity are both connected to the suction channel, and the other ends of the first suction cavity and the other ends of the second suction cavity are respectively close to the two ends of the end face of the suction head; the combined shape of the first suction cavity, the second suction cavity and the suction channel is set to a Y-shape.

[0009] Furthermore, the sum of the cross-sectional area of ​​the first suction cavity and the cross-sectional area of ​​the second suction cavity is not greater than the cross-sectional area of ​​the suction channel.

[0010] Furthermore, the narrowest part of the scraper head is set to 8mm, and the widest part of the scraper head is set to 10mm; the minimum wall thickness of the scraper is set to 1mm.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] Compared with existing technologies, this technology features a flattened suction head, which allows for scraping and tissue removal. It is also suitable for scraping and removing pus cavities, necrotic tissue, and rough surfaces, and thus has a scraping function. The end of the suction device is designed to be wide and flat, and the end face of the suction head can be made relatively sharp for scraping. This scraping function effectively removes infected lesions or tumor tissue, reducing postoperative recurrence. Furthermore, the suction head contains multiple efficient suction cavities to meet various needs for scraping and removing waste, making it highly practical. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] As attached Figure 1-10 The laparoscopic flat-head scraper includes a scraper head 1 and a rod 2. The scraper head 1 is fixedly connected to one end of the rod 2. The rod 2 has a suction channel 21 extending through both ends. The scraper head 1 has a high-efficiency suction cavity 11 communicating with the suction channel 21. The suction tube installed at the end of the rod 2 away from the scraper head 1 communicates with the suction channel 21, so that the hollow high-efficiency suction cavity 11 inside the scraper head 1 can perform suction function.

[0030] The scraping head 1 is designed to be flat, so that it can be used to scrape and peel off tissue. It is also suitable for scraping and removing abscesses, necrotic tissue and rough surfaces. It also has a scraping function. The end of the scraper is designed to be wide and flat, and the end face of the scraping head 1 can be set to be sharp for scraping. Through the scraping function, infected lesions or tumor tissue can be effectively removed, reducing postoperative recurrence.

[0031] The width of the scraper head 1 is not less than the diameter of the rod body 2, the thickness of the scraper head 1 is not greater than the diameter of the rod body 2, and the shape of the rod body 2 is set as cylindrical.

[0032] The flat shape of the suction head 1 can be selected as follows:

[0033] 1. The thickness of the scraper head 1 gradually decreases from the end near the rod 2 to the end away from the rod 2; while the width of the scraper head 1 gradually increases from the end near the rod 2 to the end away from the rod 2.

[0034] 2. The scraper head 1 has a uniform thickness; while the width of the scraper head 1 gradually increases from the end closer to the rod 2 to the end farther away from the rod 2.

[0035] The connection between the suction head 1 and the rod 2 is a smooth, rounded surface, and the high-efficiency suction cavity 11 is seamlessly connected to the suction channel 21.

[0036] Example 1: As shown in the attached document Figure 2-4 As shown, the high-efficiency suction chamber 11 includes a wide scraping suction chamber 111, which is flat in shape so that the scraping suction head 1 can scrape using the flat shape, and can also collect more and larger tissue waste using the wide scraping suction chamber 111.

[0037] Example 2: As shown in the attached document Figure 5-7 As shown, the high-efficiency suction cavity 11 includes a narrow scraping suction cavity 112. The narrow scraping suction cavity 112 is flat in shape, and the cross-sectional area of ​​the narrow scraping suction cavity 112 is not greater than the cross-sectional area of ​​the suction channel 21. This allows the scraping suction head 1 to also suction out waste when it scrapes. Since the suction area of ​​the narrow scraping suction cavity 112 is not greater than the suction area of ​​the suction tube, the suction force of the narrow scraping suction cavity 112 is not lower than the suction force of the conventional suction tube.

[0038] Example 3: Appendix Figure 8-10 As shown, the high-efficiency suction chamber 11 includes a first suction chamber 113 and a second suction chamber 114. One end of the first suction chamber 113 and one end of the second suction chamber 114 are both connected to the suction channel 21. The other ends of the first suction chamber 113 and the second suction chamber 114 are respectively close to the two ends of the end face of the scraping head 1. The combined shape of the first suction chamber 113, the second suction chamber 114 and the suction channel 21 is set to a Y-shape. This allows the first suction chamber 113 and the second suction chamber 114 to be used to collect tissue residue when the scraping head 1 is scraping. If one of them becomes blocked, the other is used, and the suction function is still achieved.

[0039] In a preferred embodiment, as shown in the appendix Figure 8-10 As shown, the sum of the cross-sectional area of ​​the first suction cavity 113 and the cross-sectional area of ​​the second suction cavity 114 is not greater than the cross-sectional area of ​​the suction channel 21; so as to ensure that the suction force of the first suction cavity 113 and the second suction cavity 114 is not lower than the suction force of a conventional suction tube.

[0040] In a preferred embodiment, as shown in the appendix Figure 1-10As shown, the narrowest part of the scraper head 1 is set to 8mm, and the widest part of the scraper head 1 is set to 10mm; the minimum wall thickness of the scraper is set to 1mm; so that the scraper head 1 can better utilize its end to scrape and peel tissue.
