Description

Multi-channel polyp trap Technical Field

[0001] The present application relates to the technical field of polyp collectors, and in particular to a multi-channel polyp collector. Background Art

[0002] Polyps are growths on the surface of human tissue. Modern medicine generally refers to any growth on the surface of human mucosa as polyps, including hyperplastic, inflammatory, hamartoma, adenoma, and other tumors. For most polyps, endoscopic resection is the preferred treatment. This procedure involves inserting an endoscope into the body and using tools such as a cutter, electrocoagulator, and biopsy forceps to completely remove the polyp from the mucosal surface.

[0030] A multi-channel polyp trap according to an embodiment of the present application will be described with reference to FIGS. 1 to 6 .

[0031] As shown in Figures 1 to 6, the multi-channel polyp capture device of the embodiment of the present application includes a cup body 100; a collecting assembly 200, the collecting assembly 200 includes a fixing seat 210 and a plurality of capture chambers 220, the fixing seat 210 is arranged in the cup body 100, and the plurality of capture chambers 220 are detachably arranged on the upper side of the fixing seat 210, and the plurality of capture chambers 220 are evenly distributed along the circumference of the fixing seat 210, and the lower side of the fixing seat 210 and the cup body 100 are enclosed to form a cavity 230, a through hole is opened in the middle of the fixing seat 210, and a plurality of first buckling parts 211 are provided on the inner wall of the through hole; a cover body 300, the cover body 300 is rotatably arranged on the cup body 100, and the cover body 300 and the cup body are connected. 100 is detachably connected, and a first conduit 310 and a second conduit 320 are provided on the cover body 300. The first conduit 310 and the cover body 300 are coaxially arranged. The end of the first conduit 310 away from the cover body 300 can be connected to the endoscope, and the other end of the first conduit 310 extends to the cavity 230 through the through hole. A plurality of second buckling portions 311 that can cooperate with the first buckling portion 211 are provided on the outer wall of the first conduit 310, and the end of the second conduit 320 away from the cover body 300 is connected to the air pump; when the cover body 300 is rotated, the plurality of second buckling portions 311 are alternately buckled with the plurality of first buckling portions 211, so that the second conduit 320 is connected to the plurality of capture chambers 220 in sequence.

[0032] As shown in Figures 1 and 2, any horizontal cross-section of the cup body 100 is circular, and a fixing seat 210 is provided on the cup body 100. The fixing seat 210 is a circular plate corresponding to the inner diameter of the cup body 100. Four capture chambers 220 are detachably provided on the upper side of the fixing seat 210. The four capture chambers 220 are evenly distributed around the axis of the fixing seat 210. The lower side of the fixing seat 210 and the cup body 100 are enclosed to form a cavity 230, and four first buckling parts 211 are provided on the fixing seat 210. The cover body 300 is rotatably disposed on the cup body 100, and the cover body 300 is detachably connected to the cup body 100. A first tube 310 and a second tube 320 are provided on the cover body 300. The upper end of the first tube 310 is connected to the endoscope, and the lower end extends to the cavity 230 below through the fixing seat 210. Four second buckling parts 311 are provided on the first tube 310, and the four second buckling parts 311 can be buckled with the four first buckling parts 211 respectively. The second tube 320 extends upward, and the upper end is connected to the air pump for catching the fallen polyps. During the resection operation, the endoscope connected to the first catheter 310 enters the human body. After the medical staff uses the tool to remove the polyp, the polyp enters the second catheter 320 along the pipeline under the action of the air pump, and finally falls into the limiting groove corresponding to the second catheter 320. After completing the last polyp collection, the medical staff rotates the cover body 300 to separate the four second buckling parts 311 and the four first buckling parts 211 from each other and then buckle with each other again, thereby achieving rapid fixation of the second catheter 320 and the limiting groove, thereby ensuring that the second catheter 320 and the idle limiting groove can be accurately connected. The buckling of the second buckling parts 311 and the first buckling parts 211 provides a tactile indication to the medical staff, which can convey to the medical staff that the second catheter 320 is in place, thereby reducing the medical staff's operating steps, improving the efficiency of the operation, and enabling the doctor to accurately obtain the target tissue sample, thereby improving the quality of the tissue sample.

[0033] Specifically, the cup body 100, the cover body 300, the first conduit 310, the second conduit 320, and the capture chamber 220 are all made of transparent materials to ensure that medical personnel can directly observe the collection of polyp tissue. It is conceivable that there can be two, three, five, or other multiple capture chambers 220, and the multiple capture chambers 220 are evenly distributed along the circumference of the fixing base 210. Correspondingly, at least one structure of the first snap-fitting portion 211 and the second snap-fitting portion 311 needs to be provided with a number corresponding to the number of capture chambers 220 to ensure that each second conduit 320 is connected to the capture chamber 220 in sequence, allowing medical personnel to obtain location information through touch or hearing. Multiple capture chambers 220 can collect as many polyp tissues as possible without replacing the multi-channel polyp capturer, thereby simplifying the operation. Of course, the more capture chambers 220 are set, the smaller the space that the capture chamber 220 can accommodate polyps. However, it should be noted that polyps are usually abnormal tissues, and their shape and position may pose challenges to effective sample collection. Therefore, a capture chamber 220 of appropriate size can provide better control and precision, allowing doctors to accurately obtain target tissue samples, thereby improving the quality and reliability of sampling.

[0034] In some specific embodiments of the present application, a plurality of elastic members 212 are provided on the fixing seat 210, the plurality of elastic members 212 are located in the cavity 230, the plurality of elastic members 212 are evenly arranged around the first tube 310, a plurality of first buckling portions 211 are arranged one by one on the plurality of elastic members 212, the plurality of first buckling portions 211 are respectively located on the side of the plurality of elastic members 212 close to the first tube 310, a plurality of second buckling portions 311 are arranged on one end of the first tube 310 in the cavity, and the plurality of second buckling portions 311 are located on the side of the first tube 310 close to the elastic member 212.

[0035] As shown in Figure 3, four elastic members 212 are provided on the lower side of the fixing seat 210. The four elastic members 212 are arranged in a circumferential direction around the first tube 310, and the four elastic members 212 are respectively provided with a first buckling portion 211, and the first buckling portion 211 is located on the side of the elastic member 212 close to the first tube 310. Correspondingly, four second buckling portions 311 are provided, and the four second buckling portions 311 are arranged on the side of the elastic member 212 at one end of the first tube 310 passing through the fixing seat 210. When the cover body 300 is rotated, the four elastic members 212 are deformed in an axial direction away from the first tube 310, so that the first tube 310 can rotate relative to the fixed base 210 as the cover body 300 rotates, and the four second snap-fitting portions 311 are alternately snap-fitted with the four first snap-fitting portions 211. Therefore, when the second tube 320 reaches the set position and is connected to the capture chamber 220, the four second snap-fitting portions 311 are snap-fitted with the four first snap-fitting portions 211 one by one, so that medical staff can obtain real-time information during use.

[0036] In some specific embodiments of the present application, a plurality of third snap-fitting portions 340 are further provided on the cover body 300, and the plurality of third snap-fitting portions 340 are evenly arranged around the first conduit 310. A sleeve 213 is provided on the fixing seat 210, and the first conduit 310 extends into the cavity 230 through the sleeve 213. A plurality of fourth snap-fitting portions 214 corresponding to the plurality of third snap-fitting portions 340 are provided on the side of the sleeve 213 close to the cover body 300. The cover body 300 is rotated to make the second conduit 320 and the plurality of capture chambers 220 alternately connected in sequence, and the plurality of third snap-fitting portions 340 and the plurality of fourth snap-fitting portions 214 are alternately snap-fitted in sequence.

[0037] As shown in Figures 2, 4 and 5, four third buckling parts 340 are provided on the lower side of the cover body 300. The four third buckling parts 340 are evenly arranged around the first conduit 310. A sleeve 213 is provided on the fixing seat 210. The first conduit 310 passes through the sleeve 213 and enters the cavity 230. Four fourth buckling parts 214 corresponding to the four third buckling parts 340 are provided on the upper side of the sleeve 213. The four fourth buckling parts 214 can be alternately buckled with the four third buckling parts 340. Thus, when the cover body 300 is rotated, the first conduit 310 is rotated. During the operation, the four third fastening parts 340 on the lower side of the cover body 300 will also rotate with the rotation of the cover body 300. Each time when the second tube 320 reaches the corresponding position and is connected to one of the four capture chambers 220, the four third fastening parts 340 will be re-fastened with the four fourth fastening parts 214. On the one hand, the reliability of the fastening and the consistency of the corresponding connection between the second tube 320 and the capture chamber 220 are enhanced. On the other hand, it further helps medical staff understand the status of the structure and reduces the possibility of accidents caused by misoperation.

[0038] In this specific embodiment, the third fastening portion 340 is a groove. Specifically, the third fastening portion 340 is a groove with a trapezoidal vertical cross-section. Correspondingly, the fourth fastening portion 214 is a protrusion, and the fourth fastening portion 214 is a trapezoidal protrusion corresponding to the third fastening portion 340. The inclined surface of the trapezoidal protrusion has a transitional effect on the fastening of the structure, ensuring that the protrusion and the groove are fastened while also being able to separate from each other by rotating the cover body 300, thereby entering the next fastening. Of course, conversely, the third fastening portion 340 can be a protrusion, and the fourth fastening portion 214 can be a groove corresponding to the third fastening portion 340.

[0039] In some specific embodiments of the present application, a plurality of protrusions 330 are provided on the side wall of the cover body 300 close to the cup wall of the cup body 100, and an annular groove 110 is provided on the side of the cup wall of the cup body 100 close to the cover body 300. A plurality of notches 111 corresponding to the plurality of protrusions 330 are provided on the upper side of the annular groove 110. The plurality of protrusions 330 enter the annular groove 110 through the plurality of notches 111. Rotating the cover body 300 causes the plurality of protrusions 330 to move in the direction restricted by the annular groove 110, thereby making the cover body 300 and the cup body 100 rotatably connected.

[0040] As shown in Figures 4 to 6, the annular side wall of the cover 300 is provided with two protrusions 330 on the side close to the cup wall of the cup body 100, and the cup wall of the cup body 100 is provided with an annular groove 110 on the side close to the cover 300. The upper side of the annular groove 110 is provided with two notches 111 corresponding to the two protrusions 330. In this specific embodiment, the two protrusions 330 are arranged opposite to each other, and the two notches 111 are correspondingly arranged opposite to each other. The cover 300 is closed from the top of the cup body 100 downwards, first allowing the two protrusions 330 to pass through the two corresponding notches 111 and enter the annular groove 110. Then, the cover 300 is rotated to allow the two protrusions 330 to move along the channel restricted by the annular groove 110, thereby realizing a detachable rotation connection between the cover 300 and the cup body 100. Of course, the number of the protrusions 330 may be one, three, four, or more, and the number of the notches 111 may also be one, three, four, or more, so that the protrusions 330 can pass through the notches 111 and enter the annular groove 110 .

[0041] It can be imagined that, on the contrary, the cup wall of the cup body 100 close to the side of the cover body 300 can be provided with a plurality of protrusions 330, and the side wall of the cover body 300 close to the side of the cup wall of the cup body 100 can be provided with an annular groove 110, and the upper side of the annular groove 110 is provided with a plurality of notches 111 corresponding to the plurality of protrusions 330, and the plurality of protrusions 330 enter the annular groove 110 through the plurality of notches 111. Rotating the cover body 300 can also make the protrusions 330 move in the direction restricted by the annular groove 110, and make the cover body 300 and the cup body 100 rotatably connected.

[0042] In some specific embodiments of the present application, a plurality of limiting blocks 215 are provided on the fixing base 210 , and the plurality of limiting blocks 215 are used to limit the position of the capture chamber 220 on the fixing base 210 .

[0043] In some specific embodiments of the present application, a plurality of first through holes 221 are defined at the bottom of the plurality of capture chambers 220 , a plurality of second through holes 216 are defined on the fixing base 210 , and a gap is formed between the plurality of capture chambers 220 and the fixing base 210 .

[0044] As shown in Figures 2 and 3, the fixing base 210 is provided with a plurality of stoppers 215. In this specific embodiment, each capture chamber 220 corresponds to four stoppers 215, and each capture chamber 220 is inserted into a position restricted by the four stoppers 215. The bottom of each capture chamber 220 is provided with a plurality of first through-holes 221, and the fixing base 210 is also provided with a plurality of second through-holes 216. Specifically, the edge of the fixing base 210 has an annular ridge, and the capture chamber 220 is mounted on the annular ridge. The position of the capture chamber 220 is limited by the stoppers 215, thereby forming a gap between the capture chamber 220 and the fixing base 210. As a result, when polyps fall into the capture chamber 220, they can be filtered through the first through-holes 221 and the second through-holes 216, and substances other than the polyp tissue are filtered into the cavity 230, ensuring that medical staff can effectively collect and retain the polyp tissue and preventing it from being lost or contaminated during the collection process.

[0045] In some specific embodiments of the present application, an identification portion 350 is provided on the cover 300 , and the identification portion 350 is used to indicate the communication status between the second conduit 320 and the plurality of capture chambers 220 .

[0046] As shown in Figure 3, an identification portion 350 is provided on the side wall of the cover body 300. When the cover body 300 is rotated to make the second catheter 320 correspond to the capture chamber 220, the identification portion 350 will point to the capture chamber 220. In this specific embodiment, the identification portion 350 is a frame-shaped structure, and triangular protrusions are provided on the upper side and left and right sides of the frame structure. The triangular protrusions all point to the capture chamber 220 exposed in the center of the frame structure, providing medical staff with a visual confirmation structure to judge the corresponding status of the second catheter 320 and the capture chamber 220, further extending the use value of the multi-channel polyp capturer.

[0047] In some specific embodiments of the present application, the second locking portion 311 is a straight groove provided along the extending direction of the first conduit 310 .

[0048] As shown in FIG3 , the second fastening portion 311 is a straight groove arranged along the extension direction of the first conduit 310. Correspondingly, the first fastening portion 211 is a protrusion that can move along the straight groove. Since the cover 300 and the cup body 100 will undergo relative vertical movement during the relative rotation, the groove is designed to be elongated to increase the contact area between the groove and the protrusion, thereby providing more contact points and increasing the stability and tightness of the connection. Furthermore, when the first conduit 310 is inserted into the sleeve 213, the straight groove can guide the protrusion to buckle in, making it easier for it to slide into the straight groove, thereby improving positioning accuracy, reducing deviations and errors during assembly, and simplifying the installation and disassembly process of the component.

[0049] In some specific embodiments of the present application, a guiding portion 312 is provided at the end of the first catheter 310 away from the end connected to the endoscope. The guiding portion 312 is used to guide the first catheter 310 to pass through the fixing seat 210 and enter the cup body 100.

[0050] As shown in Figures 3 and 4, a guiding portion 312 is provided at the lower end of the first catheter 310. The cross-sectional area of ​​the guiding portion 312 gradually increases from bottom to top. The guiding portion 312 can guide the direction of the first catheter 310 when the first catheter 310 is inserted into the sleeve 213 of the fixing seat 210.

[0051] In some specific embodiments of the present application, the first conduit 310 is provided with a first transition portion 313, and the cross-sectional area of ​​the first transition portion 313 gradually decreases in the direction away from the cover body 300, and the second conduit 320 is provided with a second transition portion 321, and the cross-sectional area of ​​the second transition portion 321 gradually decreases in the direction away from the cover body 300.

[0052] As shown in Figures 1, 3 and 4, a first transition portion 313 is provided at the upper end of the first conduit 310, and the cross-sectional area of ​​the first transition portion 313 gradually decreases from bottom to top. A second transition portion 321 is provided at the upper end of the second conduit 320, and the cross-sectional area of ​​the second transition portion 321 gradually decreases from bottom to top. When the first conduit 310 and the second conduit 320 need to be connected to the equipment through a pipeline, by providing the first transition portion 313 and the second transition portion 321, a tight connection can be ensured between the interfaces, thereby reducing the risk of air leakage or liquid leakage, and when the second conduit 320 is connected to the air pump, the second transition portion 321 can provide a larger contact area to withstand pressure or tension, so as to reduce the risk of the interface loosening or falling off. At the same time, the provision of the first transition portion 313 and the second transition portion 321 can also simplify the installation process, making the two interfaces easier to align during installation, reducing the difficulty and errors during installation, which helps to improve work efficiency and reduce problems caused by installation errors.

[0053] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
