Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a magnetic endoscope binding mechanism. Background Technology

[0002] Endoscopes are categorized based on their application, including bronchoscopes, colonoscopes, and gastroscopes. Generally, an endoscope consists of two parts: a handle and an imaging catheter connected to the handle. The endoscope functions primarily as an instrument for examining lesions. After the imaging catheter (with a camera at its tip) enters the body's natural cavities, the endoscope simply acts as an examination tool, taking photos or videos. The images captured by the camera are transmitted photoelectrically to a monitor connected to the endoscope handle, allowing doctors to observe whether lesions (such as polyps or early-stage cancer) are present within the body's natural cavities. Even if a lesion is detected by the imaging catheter's camera, the endoscope itself does not perform surgery. The imaging catheter has an instrument channel, and the handle has a forceps channel, which connects to the instrument channel. When encountering diseased tissue that needs to be treated, such as polyps, the doctor will insert a snare or similar endoscopic minimally invasive surgical consumable into the forceps channel through the imaging catheter to reach the target diseased tissue. Then, the polyp removal surgery will be performed. After the removal is completed, the snare will be removed from the endoscope handle. If bleeding is detected by the imaging catheter lens after the removal, a hemostatic clamp will be inserted into the forceps channel. The hemostatic clamp will be released to close the tissue and compress it to stop the bleeding.

[0003] Cholangioscopy, as the name suggests, is used to diagnose and treat diseases occurring within the bile duct (usually gallstones). The bile duct is long and narrow; ordinary endoscopes, such as duodenoscopes, have imaging catheters with a diameter close to 2 cm, which are clearly unsuitable for directly treating biliary tract lesions. In this case, a cholangioscopy (which also includes a handle and imaging catheter, with a clamping port on the handle and an instrument channel in the imaging catheter) is used, much like the aforementioned snare or hemostatic clip, as a minimally invasive surgical consumable. The imaging catheter of the cholangioscopy (which is very thin, generally less than 3 mm) is inserted into the clamping port of the endoscope (usually a duodenoscope), and then further into the bile duct via the imaging catheter of the duodenoscope to perform stone removal or live sampling.

[0004] As can be seen from the above, the choledochoscope (which is generally very cheap, worth around 2,000 RMB) is used in conjunction with the duodenoscope (also known as the mother endoscope, which is generally very expensive, worth several million RMB) as a daughter endoscope. It is not used independently. During surgery, the doctor needs to hold both the duodenoscope and the choledochoscope at the same time. Once the mother endoscope (duodenoscope) reaches the vicinity of the bile duct, it cannot be moved at will. Therefore, during surgery, it is necessary to keep the daughter endoscope (choledochoscope) and the mother endoscope (duodenoscope) relatively fixed. However, in the current technology, it is inconvenient to assemble and disassemble the mother endoscope and the connection between the two is not strong. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to solve the problem that the mother endoscope and daughter endoscope are inconvenient to install and disassemble and the connection strength between them is not high in the prior art, a magnetic endoscope binding mechanism is provided.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a magnetic endoscope binding mechanism for detachably connecting a mother endoscope and a daughter endoscope, comprising:

[0007] A mother mirror holder is used to connect the mother mirror;

[0008] Sub-mirror mounting bracket, used to connect the sub-mirror;

[0009] The magnetic attraction mechanism includes a snap-fit ​​protrusion and a snap-fit ​​groove located on the mother mirror fixing base and the daughter mirror fixing base, respectively. The snap-fit ​​protrusion snaps into the snap-fit ​​groove to restrict relative rotation between the mother mirror and the daughter mirror. The snap-fit ​​groove is provided with a first magnetic attraction element, and the snap-fit ​​protrusion is provided with a second magnetic attraction element that is magnetically attracted and fixed to the first magnetic attraction element.

[0010] Furthermore, both the snap-fit ​​protrusion and the snap-fit ​​groove have rectangular cross-sections.

[0011] Furthermore, the bottom of the snap-fit ​​groove protrudes to form a first mounting groove for installing the first magnetic component, and the snap-fit ​​protrusion is hollow to form a cavity, and a second mounting groove for installing the second magnetic component protrudes from the cavity.

[0012] Furthermore, the mother mirror fixing base includes a detachably connected bracket and a buckle. The bracket is provided with the aforementioned snap-fit ​​protrusion or snap-fit ​​groove, and the buckle is provided with a gripper for holding the mother mirror.

[0013] Furthermore, the first magnetic component is bonded and fixed inside the first mounting groove, and the second magnetic component is bonded and fixed inside the second mounting groove.

[0014] Furthermore, the card holder has several weight-reducing grooves on the side near the buckle.

[0015] Furthermore, the card holder and the buckle are fixed by the first bolt, and the sub-mirror fixing seat and the sub-mirror are fixed by the second bolt.

[0016] The beneficial effects of this utility model are as follows: The master scope of this utility model can be used alone or in conjunction with the daughter scope to meet different surgical needs. When the master scope and the daughter scope are used together, the master scope and the daughter scope are initially positioned by the snap-fit ​​protrusion and snap-fit ​​groove. Then, the master scope and the daughter scope are fixed by the attraction of the first magnetic suction component and the second magnetic suction component, which improves the connection strength between the master scope and the daughter scope. Moreover, the installation and removal of the magnetically fixed master scope and the daughter scope are convenient and quick, which improves the operation efficiency. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0031] like Figures 1-3 As shown, a magnetic endoscope binding mechanism is used to detachably connect a mother endoscope 1 and a daughter endoscope 2, comprising:

[0032] The master mirror holder 3 is used to connect the master mirror 1. The master mirror 1 includes a first handle and a first imaging guide tube (not shown in the figure). A first instrument channel is formed inside the first imaging guide tube.

[0033] Sub-scope mounting base 4 is used to connect the sub-scope 2. The sub-scope 2 includes a second handle and a second imaging conduit (not shown in the figure). A second instrument channel is formed inside the second imaging conduit. The diameter of the second imaging conduit is smaller than the diameter of the first instrument channel, that is, the second imaging conduit can pass through the first instrument channel.

[0034] The magnetic attraction mechanism includes a snap-fit ​​protrusion 401 and a snap-fit ​​groove 303 located on the mother mirror holder 3 and the daughter mirror holder 4, respectively. Specifically, the snap-fit ​​protrusion 401 can be located on the mother mirror holder 3 and the snap-fit ​​groove 303 on the daughter mirror holder 4, or the snap-fit ​​protrusion 401 can be located on the daughter mirror holder 4 and the snap-fit ​​groove 303 on the mother mirror holder 3. In this embodiment, the snap-fit ​​protrusion 401 is located on the daughter mirror holder 4. The snap-fit ​​protrusion 401 engages with the snap-fit ​​groove 303 to initially position the mother mirror 1 and the daughter mirror 2. The system restricts the relative rotation of the mother mirror 1 and the daughter mirror 2. The locking groove 303 is provided with a first magnetic suction member 304, and the locking protrusion 401 is provided with a second magnetic suction member 402 that is magnetically fixed to the first magnetic suction member 304. The first magnetic suction member 304 and the second magnetic suction member 402 attract each other to fix the mother mirror 1 and the daughter mirror 2. The first magnetic suction member 304 and the second magnetic suction member 402 can both be magnets, or one of the first magnetic suction member 304 or the second magnetic suction member 402 can be a magnet and the other can be a magnetic material such as iron.

[0035] When the mother mirror 1 and daughter mirror 2 are used together, the mother mirror 1 is first fixed on the mother mirror mounting base 3, and the daughter mirror 2 is fixed on the daughter mirror mounting base 4. Then, the locking protrusions 401 and locking grooves 303 on the mother mirror mounting base 3 and the daughter mirror mounting base 4 are interlocked to prevent relative rotation between the mother mirror 1 and the daughter mirror 2. At the same time, as the locking protrusions 401 are inserted into the locking grooves 303, the first magnetic suction member 304 and the second magnetic suction member 402 attract each other to fix the mother mirror 1 and the daughter mirror 2. Then, the second imaging guide tube of the daughter mirror 2 is inserted into the clamping hole of the mother mirror 1, and through the first... One instrument channel reaches the lesion site for subsequent operations; the master scope 1 in this scheme can be used alone or in conjunction with the daughter scope 2 to meet different surgical needs. When the master scope 1 and the daughter scope 2 are used together, the master scope 1 and the daughter scope 2 are initially positioned by the snap-fit ​​protrusion 401 and the snap-fit ​​groove 303. Then, the master scope 1 and the daughter scope 2 are fixed by the first magnetic suction component 304 and the second magnetic suction component 402, which improves the connection strength between the master scope 1 and the daughter scope 2. The magnetically fixed master scope 1 and daughter scope 2 are easy and quick to install and remove, thereby improving the operation efficiency.

[0036] In some examples, the cross-sections of the snap-fit ​​protrusion 401 and the snap-fit ​​groove 303 are both rectangular structures. Of course, they can also be various regular or irregular shapes such as ellipses or polygons, as long as the snap-fit ​​protrusion 401 inside the snap-fit ​​groove 303 cannot rotate.

[0037] In some examples, such as Figure 3 As shown in Figure 4, the bottom of the snap-fit ​​groove 303 is provided with a first mounting groove 3031 for installing the first magnetic suction component 304; as shown in Figure 4, the snap-fit ​​protrusion 401 is hollow inside to form a cavity, and a second mounting groove 4011 for installing the second magnetic suction component 402 is provided inside the cavity. The height of the first mounting groove 3031 is less than the height of the snap-fit ​​groove 303 to leave space for the snap-fit ​​protrusion 401.

[0038] In some examples, the mother mirror fixing base 3 includes a detachably connected card holder 301 and a buckle 302. The card holder 301 has the aforementioned snap-fit ​​protrusion 401 or snap-fit ​​groove 303 on the side opposite to the buckle 302. The buckle 302 has a gripper 3021 for holding the mother mirror 1. The gripping surface of the gripper 3021 is a conical surface that is larger at the top and smaller at the bottom, so as to match the shape of the first handle of the mother mirror 1.

[0039] In some examples, the first magnetic member 304 is bonded and fixed inside the first mounting groove 3031, and the second magnetic member 402 is bonded and fixed inside the second mounting groove 4011.

[0040] In some examples, such as Figure 5 As shown, the card holder 301 has several weight-reducing grooves 3011 on the side near the buckle 302 to reduce the overall weight.

[0041] In some examples, the bracket 301 and the buckle 302 are fixed by the first bolt 5, that is, the bracket 301, the buckle 302 and the mother mirror 1 are all detachable, which can facilitate the installation and removal of the mother mirror 1. The daughter mirror fixing base 4 and the daughter mirror 2 are fixed by the second bolt 6, which can facilitate the installation and removal of the daughter mirror 2.

[0042] Working principle:

[0043] When the master scope 1 and the daughter scope 2 are used together, the master scope 1 is first fixed to the master scope mounting base 3 with bolts, and the daughter scope 2 is snapped into the buckle 302. Then, the snap-fit ​​protrusion 401 on the daughter scope mounting base 4 is snapped into the snap-fit ​​groove 303 on the master scope mounting base 3 to prevent the master scope 1 and the daughter scope 2 from rotating relative to each other. At the same time, during the process of the snap-fit ​​protrusion 401 being snapped into the snap-fit ​​groove 303, the first magnetic suction member 304 and the second magnetic suction member 402 attract each other to fix the master scope 1 and the daughter scope 2. Then, the second imaging catheter of the daughter scope 2 is inserted into the clamping hole of the master scope 1 and reaches the lesion site through the first instrument channel for subsequent operations.

[0044] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
