Description

Technical Field

[0001] The utility model relates to the technical field of surgical auxiliary devices, in particular to an intestinal stoma positioning device. Background Art

[0002] The so-called colostomy refers to an artificial opening made by surgeons on the abdominal wall to treat certain intestinal diseases (such as rectal cancer, ulcerative colitis, etc.). A section of the intestine is pulled out of the opening, turned over and sewed to the abdominal wall, thus forming a colostomy. Its function is to replace the original perineum anus to perform the defecation function, which is actually a diversion of the feces outlet, and has little effect on the overall digestive function.

[0003] When performing colostomy surgery, the position of the stoma is mostly determined by the experience summarized by doctors over the years. For inexperienced doctors, it is often necessary to use auxiliary devices such as rulers for positioning. For example, the Chinese patent publication number CN218074992U, which is called a transverse colostomy positioning ruler, records that a first ruler and a second ruler are perpendicular to each other, and the second ruler is slid along the length direction of the first ruler to locate the stoma. However, during colostomy surgery, it is often necessary to perform colostomies on different intestinal segments, such as the right upper abdomen or left upper abdomen for transverse colostomy; the left lower abdomen for sigmoid colon and descending colon stoma; and the right lower abdomen for ascending colon and ileum stoma. When performing surgery on different intestinal segments, the existing positioning device often needs to roughly locate the abdominal area based on experience, and then locate the colostomy position in the area. In addition, in the process of locating the colostomy, it is also necessary to avoid exceeding the range of the rectus abdominis muscles on both sides of the human body. There is a problem of insufficient convenience of use, which needs to be solved urgently. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides an intestinal stoma positioning device, which can quickly determine the stoma range according to the intestinal stoma surgery on different intestinal segments and accurately locate the stoma position within the range, effectively improving the convenience of intestinal stoma positioning.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A colostomy positioning device, characterized in that it includes a rotating disk with a belly button as a rotation base point, the rotating disk has a fan-shaped opening with an area of ​​one quarter, and two right-angled sides of the fan-shaped opening are arranged with scales, the positioning device also includes a rectus abdominis positioning strip for locating the edge position of the rectus abdominis, and the rectus abdominis positioning strip intersects with the rotation path of the fan-shaped opening.

[0007] As a further solution of the utility model: a rotating column penetrating to the lower end of the rotating disk is coaxially fixed to the upper end of the rotating disk, and a fixing seat is coaxially rotatably matched with the lower end of the rotating column, and the fixing seat can be fixed to the surface of the human body by a fixing assembly.

[0008] As a further solution of the utility model: when the fixing seat is fixed to the surface of the human body, there is a gap between the lower end surface of the rotating disk and the human body for accommodating the rectus abdominis positioning strip to pass through.

[0009] As a further solution of the utility model: the fixing assembly includes a second backing layer, a second adhesive layer and a second film layer which are fixed to the bottom of the fixing seat in sequence from top to bottom.

[0010] As a further solution of the utility model: the second adhesive layer is made of gel material, and the upper layer of the second adhesive layer is fixed to the bottom of the fixing seat through a second backing layer made of non-woven fabric.

[0011] As a further solution of the utility model: the rotating column, the fixing seat and the fixing assembly are all provided with an observation hole which passes through from top to bottom along the axis of the rotating column.

[0012] As a further solution of the utility model: the rectus abdominis positioning strip is a first backing layer, a first adhesive layer and a first film layer which are sequentially distributed from top to bottom.

[0013] As a further solution of the present invention: the first backing layer is made of non-woven fabric, and the first adhesive layer is made of gel material.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Locate the edge line of the rectus abdominis muscle through the rectus abdominis muscle positioning strip, and rotate the dial so that the fan-shaped opening with an area of ​​one quarter on the dial rotates to the left upper abdomen, left lower abdomen, right upper abdomen or left upper abdomen, and the rectus abdominis muscle positioning strip and the fan-shaped opening are enclosed to form the colostomy area. After that, a coordinate system can be established with the navel as the center of the coordinate circle, the right angle side of the fan-shaped opening parallel to the length direction of the human body as the Y axis, and the other right angle side of the fan-shaped opening as the X axis. With the help of two rulers, the colostomy position can be quickly located in the colostomy area and the size of the colostomy can be known, which effectively improves the efficiency and accuracy of colostomy area positioning and colostomy position positioning.

[0016] 2. A rotating column is coaxially fixed to the upper end of the turntable and extends to the lower end of the turntable, so that the turntable can be operated to rotate by the rotating column. In addition, the lower end of the rotating column is coaxially rotated with a fixed seat, and the fixed seat can be fixed on the surface of the human body by a fixing assembly, so that the stable positioning of the rotation base point of the turntable can be achieved. When in use, by fixing the fixed seat at the navel, the turntable and the rotating column cooperate with the fixed seat to rotate coaxially, thereby ensuring the stability of the turntable rotating with the navel as the rotation base point.

[0017] 3. When the fixing seat is fixed to the human body surface, there is a gap between the lower end surface of the rotating disk and the human body for accommodating the rectus abdominis positioning strip to pass through, which effectively reduces the interference between the rotating disk and the rectus abdominis positioning strip when the rotating disk rotates.

[0018] 4. The second adhesive layer is used to fix the fixing seat to the human body surface, which is low-cost and convenient to fix.

[0019] 5. The second adhesive layer is made of gel material. The second adhesive layer of gel material has a certain degree of stickiness, is soft in contact with the skin, and is easy to separate from the skin without remaining on the skin surface. In addition, the upper layer of the second adhesive layer 42 is fixed to the bottom of the fixing seat through the second backing layer of non-woven fabric material. The non-woven fabric has good connectivity with the gel, which facilitates the second adhesive layer to be stably fixed to the bottom of the fixing seat.

[0020] 6. A through hole is provided on the rotating column, the fixed seat and the fixed assembly along the axis of the rotating column. The setting of the observation hole makes it easy to observe the situation at the bottom center of the fixed seat from the upper end surface of the rotating column, and then facilitates the alignment of the observation hole with the navel. The fixing assembly at the bottom of the fixed seat can be fixed around the periphery of the navel, ensuring the stability of the positioning of the fixed seat.

[0021] 7. The rectus abdominis positioning strip is composed of a first backing layer, a first adhesive layer and a first film layer, which are arranged in sequence from top to bottom, so that the rectus abdominis positioning strip can be flexibly bent, which is not only convenient for the rectus abdominis positioning strip to be rolled up and stored, but also allows the rectus abdominis positioning strip to fit the surface of the human body. In addition, by tearing off the first film layer and bonding the first adhesive layer to the skin surface, the stability of the fixation of the rectus abdominis positioning strip on the human body can be ensured.

[0022] 8. The first adhesive layer is made of gel material. The first adhesive layer of gel material has a certain degree of stickiness, is soft when in contact with the skin, and is easy to separate from the skin without remaining on the skin surface. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] For ease of understanding, the specific structure and working mode of the utility model are further described below in conjunction with the accompanying drawings:

[0031] The specific structure of the utility model refers to Figure 1-5As shown, its main structure includes a rotating disk 10 with the navel as the rotation base point, a fan-shaped opening 11 on the rotating disk 10 with an area of ​​one quarter, and a rectus abdominis positioning strip 30 for locating the edge of the rectus abdominis. The rectus abdominis positioning strip 30 is a long strip structure. When in use, after the patient lies down in a supine position, the rectus abdominis positioning strip 30 is firstly arranged with the midpoint of the clavicle 61 on the left or right side of the upper limb 60 as the starting point according to the intestinal segment to be stomated (such as the left ventral side or the right ventral side), and is extended along the direction of the nipple on the same side, so as to locate the outer edge of the rectus abdominis. In addition, the rotating disk 10 is provided with two scales 12 respectively distributed along the two right-angled sides of the fan-shaped opening 11. After the rectus abdominis positioning strip 30 locates the outer edge of the rectus abdominis, by locating the axis of the rotating disk 10 at the navel of the upper limb 60 of the human body, according to the intestinal segment to be stomated (such as transverse colostomy in the right upper abdomen or left upper abdomen; sigmoid colon and descending colon stoma in the left lower abdomen; ascending colon and ileostomy in the right lower abdomen), the rotating disk 10 is rotated with the navel as the axis, and the fan-shaped opening 11 is finally rotated to correspond to the left upper abdomen, right upper abdomen, left lower abdomen or left upper abdomen, wherein, When the fan-shaped opening 11 is in the position after the final rotation stops, one side of the fan-shaped opening 11 is parallel to the length direction of the human body. Since the rotation paths of the rectus abdominis positioning strip 30 and the fan-shaped opening 11 intersect, the rectus abdominis positioning strip 30 and the inner wall of the fan-shaped opening 11 finally enclose a U-shaped enclosed area with one side open. After that, by observing the scale 12 parallel to the side of the U-shaped enclosed area, the range of 5 cm from the bottom to the opening of the U-shaped enclosed area is the specific stoma area, so that the specific stoma area of ​​the intestinal stoma can be accurately located. After that, when determining the specific stoma position, a coordinate system can be established with the navel as the center of the coordinate circle, the right angle side of the fan-shaped opening parallel to the length direction of the human body as the Y axis, and the other right angle side of the fan-shaped opening as the X axis, and then with the two scales 12, the stoma position can be quickly located in the stoma area and the size of the stoma can be known.

[0032] On the basis of the above, in order to further facilitate the rotation of the turntable 10 around its own axis, as Figure 1 As shown, a rotating column 20 is coaxially fixed to the upper end of the turntable 10 and extends to the lower end of the turntable 10, so that the turntable 10 can be operated to rotate by the rotating column 20. In addition, a fixing seat 40 is coaxially rotatably matched at the lower end of the rotating column 20, and the fixing seat 40 can be fixed on the surface of the human body by a fixing assembly, so as to achieve stable positioning of the rotation base point of the turntable 10. When in use, by fixing the fixing seat 40 at the navel, the turntable 10 and the rotating column 20 are coaxially rotatably matched with the fixing seat 40, so as to ensure the stability of the turntable 10 rotating with the navel as the rotation base point.

[0033] Specifically, Figure 3 and Figure 4As shown, the fixing assembly includes a second adhesive layer 42 and a second film layer 43 fixed to the bottom of the fixing seat 40 from top to bottom. By tearing off the second film layer 43, the second adhesive layer 42 is bonded to the human body surface. Furthermore, the second adhesive layer 42 is made of gel material. The second adhesive layer 42 of gel material has a certain viscosity, is soft in contact with the skin, and is easy to separate from the skin without remaining on the skin surface; in addition, the upper layer of the second adhesive layer 42 is fixed to the bottom of the fixing seat 40 through the second backing layer 41 of non-woven fabric material. The non-woven fabric has good connectivity with the gel, which facilitates the second adhesive layer 42 to be stably fixed to the bottom of the fixing seat 40. Of course, the second adhesive layer 42 is made of gel material, which is only a preferred embodiment. In actual implementation, the second adhesive layer 42 can also be made of other adhesive layered structures such as medical tape. In addition, the fixing component may also have other implementation modes during its specific implementation. For example, the fixing component may use a plurality of suction cups that can be adsorbed and fixed to the surface of the human body; or the bottom of the fixing component may be made of rubber or silicone material. By relying on the friction between the rubber or silicone and the surface of the human body, the fixing component may also maintain its fixing effect on the skin surface.

[0034] It is worth mentioning that in order to reduce the interference between the rotating disk 10 and the rectus abdominis positioning strip 30 when the rotating disk 10 rotates, as shown in FIG. Figure 1 As shown, when the fixing seat 40 is fixed to the surface of the human body, there is a gap between the lower end surface of the rotating disk 10 and the human body for accommodating the rectus abdominis positioning strip 30 to pass through.

[0035] In addition, in order to facilitate accurate positioning of the fixing seat 40 when it is fixed at the navel, an observation hole 50 that passes through from top to bottom is provided on the rotating column 20, the fixing seat 40 and the fixing assembly along the axis of the rotating column 20. Through the setting of the observation hole 50, it is convenient to observe the situation at the bottom center of the fixing seat 40 from the upper end surface of the rotating column 20, and then it is convenient to align the observation hole 50 with the navel. The fixing assembly at the bottom of the fixing seat 40 can be fixed around the periphery of the navel, ensuring the stability of the positioning of the fixing seat 40.

[0036] On the basis of the above, if Figure 4 As shown, the rectus abdominis positioning strip 30 is a first backing layer 31, a first adhesive layer 32 and a first film layer 33 which are sequentially distributed from top to bottom, so that the rectus abdominis positioning strip 30 can be flexibly bent, which is not only convenient for the rectus abdominis positioning strip 30 to be rolled up and stored, but also allows the rectus abdominis positioning strip 30 to fit the surface of the human body. In addition, by tearing off the first film layer 33 and bonding the first adhesive layer 32 to the skin surface, the stability of the rectus abdominis positioning strip 30 fixed on the human body can be ensured. Specifically, the first backing layer 31 is made of non-woven fabric, and the first adhesive layer 32 is made of gel material, which is the same as the second adhesive layer 42 and the second backing layer 41, and will not be repeated here.

[0037] In specific implementation, the rectus abdominis positioning strip 30 can also adopt other implementations. For example, the rectus abdominis positioning strip 30 can be made of rubber material or silicone material. Relying on the friction between rubber or silicone and the human body surface, the rectus abdominis positioning strip 30 can also maintain the fixing effect on the skin surface. In addition, silicone or rubber materials also have a good rolling and storage effect.

[0038] Of course, for those skilled in the art, the present invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
