Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a scissors for making ostomy bags easy to cut. Background Technology

[0002] Ostomy bags are primarily designed for patients with enterostomies. These patients require surgery to create an artificial intestinal opening (i.e., an "ostomy") in their abdomen for the purpose of excreting feces or intestinal fluid. In hospital departments, most enterostomy patients and their families are elderly and have poor eyesight. Using existing simple scissors to cut the ostomy bag can easily puncture it, requiring a new bag to be cut, thus increasing the financial burden on the patient. Therefore, many auxiliary tools for easier cutting have been developed for patients and their families. For example, Chinese utility model patent application number 202121844894.4 discloses an auxiliary device for cutting ostomy bags, and Chinese utility model patent application number 202120605687.7 discloses a compass cutter for cutting the bottom plate of an ostomy bag. Both use a fixed fulcrum, adjusting the cutting length, and rotating the cutting blade to cut the ostomy bag.

[0003] However, in actual use, such as the two Chinese utility model patents mentioned above, both have complex structures and require adjusting the cutting size before determining the center point, making the operation cumbersome and the practicality poor. It can be seen that many auxiliary tools that facilitate cutting still have the problem of cumbersome operation. Therefore, a scissors for ostomy bags that are easy to cut is proposed as a further improvement. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide an ostomy bag scissors that are easy to cut, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a scissor for easy cutting of ostomy bags, comprising scissor arms, two scissor arms being rotatably connected by a rotating shaft, a handle and a guide base being fixedly installed at both ends of each scissor arm, a cutting blade passing through the guide base being provided inside the guide base, and a telescopic mechanism for adjusting the moving distance of the cutting blade being provided between the cutting blade and the guide base.

[0006] The cutting blade includes: a blade body that slides inside the guide base and a cutting edge located at the edge of the blade body. The cross-section of the cutting blade extending out of the guide base is set to a semi-circular arc shape, and the shape of the cutting edge is set to a semi-circular arc shape.

[0007] The two cutting blades are staggered and their blades come into contact with each other when closed to achieve the cutting action.

[0008] Furthermore, the telescopic mechanism includes: a telescopic groove and an adjusting screw;

[0009] The telescopic groove is formed inside the guide base. The cutting blade slides inside the telescopic groove. One end of the cutting blade that extends out of the guide base is designated as the inner end, and the other end of the guide base is designated as the outer end. The adjusting screw is inserted into the telescopic groove from the outer end along the direction in which the cutting blade extends out of the guide base, and the adjusting screw is threadedly connected to the guide base. One end of the adjusting screw located inside the telescopic groove is rotatably connected to a sliding member that slides inside the telescopic groove, and the cutting blade is fixedly mounted on the sliding member.

[0010] Furthermore, the length of the scissor arm located between the handle and the rotating shaft is set to D1; the length of the scissor arm located between the guide base and the rotating shaft is set to D2; D1 > D2.

[0011] Furthermore, the thickness of the expansion groove is not less than the sum of the thicknesses of the two cutting blades.

[0012] Furthermore, a scale is provided on the outer surface of the guide base near the inner end.

[0013] Furthermore, the outer surface of the handle is covered with a rubber material for anti-slip purposes.

[0014] Furthermore, the cross-section of the guide base, which extends along the direction in which the cutting blade passes through the guide base, is set to a semi-circular arc shape.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with existing technologies, by setting the shape of the cutting blade, as the length of the cutting blade extending through the guide base increases, the width of the exposed cutting blade also increases due to the semi-circular arc shape of the blade, thus increasing the width of the stylosing bag cut in a single operation. This makes it easier for operators to adjust according to their own needs, improving practicality. The telescopic mechanism makes it convenient to control the length of the cutting blade extending through the guide base. The structure is simple and easy to operate, thus possessing high practicality.

[0017] 2. Compared with existing technologies, the addition of cutting blades at the ends of the scissor arms avoids the problem of conventional scissor tips being too long and puncturing the ostomy bag; the use of leverage saves time and effort, requiring only a light touch to control the handle to cut the ostomy bag to the correct size; and the presence of a scale on the outer surface of the guide base not only measures the size of the stoma but also the width of the cutting blades extending through the guide base.

Detailed Implementation

[0023] 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.

[0024] As attached Figure 1 and attached Figure 4 The ostomy bag scissors shown are characterized by comprising scissor arms 10, two scissor arms 10 being rotatably connected by a rotating shaft 11, and handles 20 and guide bases 30 being fixedly installed at both ends of the scissor arms 10 respectively. A cutting blade 40 is provided inside the guide base 30 and extends through the guide base 30. A telescopic mechanism 50 for adjusting the moving distance of the cutting blade 40 is provided between the cutting blade 40 and the guide base 30. The scissors formed by the rotation of the two scissor arms 10 through the rotating shaft 11 have a simple structure and are easy to use. It is only necessary to align the cutting blade 40 with the position of the ostomy bag to be cut, avoiding the blade tip of conventional scissors from piercing through the ostomy bag when cutting it.

[0025] The telescopic mechanism 50 can adjust the length of the cutting blade 40 extending out of the guide base 30. The cutting blade 40 includes a blade 41 that slides inside the guide base 30 and a blade 42 located at the edge of the blade 41. The cross-section of the cutting blade 40 extending out of the guide base 30 is a semi-circular arc shape, and the blade 42 is also a semi-circular arc shape. The two cutting blades 40 are staggered, and their blades 42 fit together when closed to achieve the cutting action. Therefore, as the length of the cutting blade 40 extending out of the guide base 30 increases, the width of the exposed cutting blade 40 also increases due to the semi-circular arc shape of the blade 42, thus increasing the width of the stylosing bag cut in a single operation. This allows operators to adjust the cutting blade 40 according to their needs, improving practicality.

[0026] In a preferred embodiment, as shown in the appendix Figure 2 As shown, the telescopic mechanism 50 includes: a telescopic groove 51 and an adjusting screw 52;

[0027] The telescopic groove 51 is formed inside the guide base 30. The cutting blade 40 slides inside the telescopic groove 51. One end of the cutting blade 40 that passes through the guide base 30 is designated as the inner end N, and the other end of the guide base 30 is designated as the outer end W. The adjusting screw 52 passes through the telescopic groove 51 from the outer end W along the direction in which the cutting blade 40 passes through the guide base 30. The adjusting screw 52 is threadedly connected to the guide base 30. One end of the adjusting screw 52 located in the telescopic groove 51 is rotatably connected to a sliding member 53 that slides in the telescopic groove 51. The cutting blade 40 is fixedly installed on the sliding member 53. The operator controls the position of the sliding member 53 in the telescopic groove 51 by rotating the adjusting screw 52. Since the sliding member 53 is connected to the cutting blade 40, the cutting blade 40 slides with the sliding member 53. The operator can then control the cutting blade 40 to pass through the telescopic groove 51, thereby controlling the length of the cutting blade 40 passing through the guide base 30, and thus determining the width of the cutting blade 40. This structure is simple and easy to operate, and therefore has high practicality.

[0028] In a preferred embodiment, as shown in the appendix Figure 1-3 As shown, the length of the scissor arm 10 located between the handle 20 and the rotating shaft 11 is set to D1, which is the length of the power arm; while the length of the scissor arm 10 located between the guide base 30 and the rotating shaft 11 is set to D2, which is the length of the resistance arm; D1 > D2, the power arm is longer than the resistance arm, thus making it easier to cut the ostomy bag. For example, Figure 1 The outer surface of the handle 20 shown is also designed with a scale for measuring the size of the ostomy bag opening.

[0029] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the thickness of the telescopic groove 51 is not less than the sum of the thicknesses of the two cutting blades 40; so that the two staggered cutting blades 40 can enter the corresponding telescopic groove 51, and the portion of the cutting blades 40 exposed outside the guide base 30 can cut the ostomy bag.

[0030] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, a scale is provided on the outer surface of the guide base 30 near the inner end N; so that the operator can measure the size of the stoma according to the scale, and adjust the cutting blade 40 to pass through the widest part of the telescopic groove 51 through the scale, thereby facilitating cutting.

[0031] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the outer surface of the handle 20 is covered with a non-slip rubber material; this increases friction and improves ease of operation.

[0032] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the cross-section of the guide base 30, which extends from the cutting blade 40 through the guide base 30, is set in a semi-circular arc shape so that the operator can see the guide base 30 and understand the shape of the cutting blade 40 at first glance, thereby helping to understand the use of the ostomy bag scissors.

[0033] Working principle of this utility model:

[0034] When in use, the ostomy bag is folded. The operator first measures the size of the stoma according to the scale, and then controls the sliding part 53 to slide in the telescopic groove 51 by rotating the adjusting screw 52. The cutting blade 40 is adjusted to pass through the widest part of the telescopic groove 51 according to the scale, that is, the width of the cutting blade 40 is adjusted according to the actual situation. Then, the operator controls the handle 20 connected to the scissor arm 10 to make the two guide bases 30 connected to the scissor arm 10 close together, and then the cutting blades 40 inside the two guide bases 30 intersect each other to cut the ostomy bag.
