Description

Technical Field

[0001] The present application relates to the technical field of endoscopic surgery auxiliary equipment, and in particular to a guide wire receiver. Background Art

[0002] With the development of modern medical technology, endoscopes, as an extension of doctors' eyes and hands, have reached the level of "penetrating every hole". As one of the key instruments in endoscopic examination equipment, guidewires play a very important role in symptom observation, disease diagnosis and surgical operations. In the relevant diagnosis and treatment operations of gastroenterology, guidewires are a key medical device, and their main functions include: guiding, creating channels, exploring paths, supporting, assisting treatment, reducing complications, and improving safety.

[0003] During an operation, there may be a situation where, after a guide wire is inserted into a patient's body in conjunction with a medical device and performs a certain function, it needs to be removed from the patient's body and then inserted into the patient's body again in conjunction with another medical device to perform another function.

[0004] During this process, since the guidewire is long and cannot be folded, and the guidewire removed from the patient's body needs to be thoroughly disinfected, the existing operation method relies on surgical assistants to manually rewind it, soak or wipe it for disinfection, and then insert it again. This will lead to the following problems:

[0005] First, the speed of winding the guide wire is difficult to control accurately and there are certain safety risks. This is because the manual winding speed depends entirely on the speed of the surgical assistant's alternating left and right hands to control the winding speed, which makes it difficult to accurately control the winding speed of the guide wire. At the same time, since the left and right hands alternately hold the guide wire to wind it, it may cause large speed and angle fluctuations in the winding of the guide wire, which may cause damage to the patient's internal tissues or organs.

[0006] Second, since the guide wire is long and cannot be folded, the efficiency of manual winding is relatively low.

[0007] Third, after the guide wire is rolled up, it needs to be disinfected with the aid of another disinfection device (for example, a vessel used for soaking disinfection or a disinfection cotton used for wiping disinfection, etc.). The whole process takes a long time, resulting in a long time interval between the withdrawal of the guide wire from the patient's body and the second insertion into the patient's body, which has a significant adverse effect on the efficiency of the operation.

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0046] In the description of this application, it should be noted that the terms used, such as "first" and "second", are only used to distinguish expressions, and do not indicate or imply differences in importance or order; the terms used, such as "inner" and "outer", refer to the inside and outside of a specific contour. The use of the above terms is only to facilitate a clear and simple description of the technical solution of this application, and cannot be understood as a limitation of this application.

[0047] In order to facilitate relevant technical personnel to have a clearer and more accurate understanding of the technical solution of the present application, the following is a relatively detailed description of the guide wire itself, the role of the guide wire and the medical devices that may be used with it, and why the guide wire needs to be used a second time in an operation.

[0048] First, as for the guide wire itself, the guide wire is generally made of metal wire (stainless steel, nickel-titanium alloy or other special alloys), with high overall hardness and good elasticity and flexibility, and its approximate length is between 150 cm and 400 cm. In other words, the guide wire is relatively long, generally placed in a roll, and cannot be folded.

[0049] Second, guidewires can be used in conjunction with a variety of medical devices during surgery and can play a variety of roles. Among them, the medical devices used can be: catheters, balloons, stents, filters, thrombus removal devices, stone baskets or lithotripsy devices, drainage tubes, biopsy needles, electrophysiological catheters, and grinding heads. In addition, the role of guidewires can include: guidance (guiding catheters, stents or balloons, etc. into specific locations in the patient's body), channel creation (using guidewires to create channels so that subsequent medical devices can smoothly pass through narrow or curved cavities), exploration paths (using guidewires to help doctors explore the path of cavities when they cannot be directly observed), support (using guidewires to provide support for catheters or other devices to keep them in the required position), auxiliary treatment (mainly including: stenosis dilatation, guided stent placement, lesion drainage and angiography, etc.), reducing complications (using guidewires for guidance helps reduce complications such as perforation and bleeding), improving safety (using guidewires can improve the accuracy and safety of endoscopic operations and reduce unnecessary risks), etc.

[0050] Third, during the operation, the guide wire is generally used as a disposable device, that is, it is removed from the patient's body and discarded after use. However, from the perspective of doctor-patient relationship and surgical costs, for a surgery on the same patient, if the patient's surgery requires multiple (more than two) guide wires, generally a guide wire will be used multiple times (that is, as described in the scenario in the background technology, after the guide wire completes a function with a certain device, it is removed from the patient's body and then sterilized and inserted again with another device. For example, the guide wire needs to be supported by a catheter first, and then with a thrombus removal device for thrombus removal) to avoid unnecessary misunderstandings about the number of surgical consumables (i.e., guide wires) used by patients and their families after the operation, saving communication costs and surgical costs.

[0051] In the existing related technologies, the guide wire is directly used in the operation by sterile packaging in a plastic packaging bag. That is, when the doctor needs to use the guide wire, he needs to remove the guide wire from the packaging bag and insert it with a certain instrument. After completing a certain function, the guide wire is removed and disinfected, and then inserted again with another instrument.

[0052] During the process of evacuating and disinfecting the guide wire, the guide wire is usually manually reeled in and disinfected, which may lead to the following technical problems as described in the background technology: First, the speed of reeling in the guide wire is difficult to accurately control and there are certain safety risks. Second, since the guide wire is long and cannot be folded, the efficiency of manual reeling is relatively low. Third, the time from evacuation to disinfection is long, which affects the efficiency of the operation.

[0053] In view of this, the present application provides a new solution, namely the guidewire retractor of the present application. The guidewire retractor of the present application can not only effectively achieve a relatively uniform and controllable guidewire winding speed, avoiding possible safety risks, but also effectively improve the guidewire winding efficiency; in addition, it can also effectively reduce the time interval between the withdrawal of the guidewire from the patient's body and the second insertion into the patient's body, so as to reduce the adverse effect on the efficiency of the operation.

[0054] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0055] Example 1

[0056] like Figures 1 to 11 As shown, the present embodiment provides a guide wire receiver 100, comprising a cover body 1, a box body 2, an operating rod 3 and a wire take-up drum 4; the cover body 1 and the box body 2 are detachably coupled to form a receiving chamber 101 for receiving the wire take-up drum 4; the cover body 1 is provided with a receiving through hole 11 which is interconnected with the receiving chamber 101; the box body 2 is provided with a lead-out through hole 21 for the guide wire to pass through; the operating rod 3 is rotatably inserted into the receiving through hole 11, and one end of the operating rod 3 is connected to the wire take-up drum 4, and the other end of the operating rod 3 extends to the outside of the receiving chamber 101.

[0057] To facilitate understanding by relevant technical personnel, the working principle / working process of the guidewire receiver 100 of the present application is first described below:

[0058] During the surgical preparation stage, the guide wire is removed from the packaging bag, and the cover body 1 and the box body 2 of the guide wire receiver 100 of the present application are disassembled (it should be noted that at this time, the cover body 1, the operating rod 3 and the take-up reel 4 are in an assembled state, and the box body 2 is independent of the above structure), and then one end of the guide wire is fixed to the take-up reel 4, and then the guide wire is wound around the take-up reel 4, and the box body 2 is brought close to the cover body 1, and the other end of the guide wire is passed through the lead-out through hole 21 on the box body 2 to expose it to the guide wire receiver 100, and the box body 2 is assembled with the cover body 1, and the surgical preparation work of the guide wire is completed.

[0059] When the guide wire needs to be inserted for the first time, the operator can pull the end of the guide wire that is exposed from the guide wire receiver 100 and gradually insert the guide wire into the patient's body.

[0060] When the guide wire needs to be withdrawn from the patient's body, the wire take-up reel 4 can be rotated by rotating the operating lever 3, thereby driving the guide wire to be withdrawn from the patient's body at a relatively uniform speed and a relatively stable angle. After the withdrawal is completed, the disinfectant can be injected into the accommodating cavity 101 through the outlet through hole 21 to quickly achieve the immersion disinfection of the guide wire. After the disinfection is completed, the disinfectant is discharged through the outlet through hole 21, and then the second insertion can be performed (the second insertion is similar to the first insertion, and no further description is given here).

[0061] Through the above technical solution, on the one hand, the guidewire receiver 100 of the present application can be withdrawn from the patient's body at a relatively uniform speed and a relatively stable angle. In this way, not only can the withdrawal speed and angle of the guidewire be effectively controlled, but also large fluctuations in angle and speed of the guidewire during the withdrawal process can be avoided, thereby avoiding damage to the tissues or organs in the patient's body.

[0062] On the other hand, the operator can achieve faster winding of the guide wire by rotating the operating rod 3, which is beneficial to effectively improve the guide wire winding efficiency.

[0063] On the one hand, after the guide wire is rolled up, the guide wire receiver 100 of the present application can be used as a disinfection container to quickly and thoroughly disinfect the guide wire, thereby minimizing the time interval between the withdrawal of the guide wire from the patient's body and the second insertion into the patient's body, thereby effectively reducing the adverse effects on surgical efficiency.

[0064] In the above embodiment, it can be understood that, first, there are many ways to fix the guide wire on the take-up drum 4, for example, a perforation can be set at a certain position on the take-up drum 4, and the guide wire can be tied to the perforation, or a clamp can be set at a certain position on the take-up drum 4, and one end of the guide wire can be clamped by the clamp to achieve fixation. This application does not make specific limitations on this.

[0065] Second, when the guide wire is rolled into the guide wire receiver 100 for disinfection, the partially exposed guide wire can guide the disinfectant, and at the same time, can effectively ensure that the disinfectant thoroughly and effectively rinses or soaks the entire guide wire. In addition, when the disinfectant is discharged, the partially exposed guide wire can also play a role in diversion, so that the disinfectant can be discharged more quickly and smoothly.

[0066] Third, the winding speed of the guide wire can be controlled by adjusting the rotation speed of the operating rod 3. In addition, the radial size of the take-up drum 4 can be designed according to the curling capacity of the guide wire, and its specific size is not specifically limited in this application.

[0067] In one embodiment of the present application, Figures 1 to 3 As shown, the guide wire receiver 100 of the present application may further include a holding handle 5, the holding handle 5 includes a first section 51 and a second section 52 connected to each other, the end of the first section 51 away from the second section 52 is connected to the cover body 1, and the first section 51 is located above the accommodating through hole 11, the second section 52 and the cover body 1 are spaced apart from each other, and the end of the second section 52 away from the first section 51 extends to below the accommodating through hole 11; in the direction from the cover body 1 to the holding handle 5, at least part of the projection of the accommodating through hole 11 falls within the projection of the second section 52.

[0068] Thus, by using the gripping handle 5 configured in this way, on the one hand, it is possible to achieve single-handed gripping and operation, which is conducive to improving the convenience of using the guidewire receiver 100 of the present application in surgery. Figure 1 During the operation, the operator can hold the holding handle 5 with his left hand, that is, hold the guide wire receiver 100 of the present application with one hand. At the same time, the operator can hold the holding handle 5 with the palm, little finger, ring finger and middle finger of his left hand, and use the index finger and thumb of his left hand to control the rotation of the operating lever 3, that is, achieve one-handed operation.

[0069] On the other hand, due to the shielding of the second section 52, it is possible to effectively avoid accidental touching of the operating rod 3 between the cover body 1 and the second section 52, and avoid the movement of the guide wire (continued extension or withdrawal) due to accidental touching of the operating rod 3 during the operation, which is beneficial to improving the safety of related operations.

[0070] In one embodiment of the present application, Figure 2 and Figure 6 As shown, the operating rod 3 of the present application may include a coaxially connected connecting section 31 and an adjusting disk 32, wherein one end of the connecting section 31 away from the adjusting disk 32 is connected to the take-up disk 4, and the radial dimension of the adjusting disk 32 is larger than the radial dimension of the connecting section 31; and there is a preset distance between the adjusting disk 32 and the second section 52.

[0071] In this way, the adjustment disk 32 configured in this way can not only limit the position of the operating rod 3 to improve the stability of the take-up reel 4, but also make it easier for the operator to rotate it with the thumb and index finger. In addition, the preset distance between the adjustment disk 32 and the second section 52 can be adjusted as needed to facilitate the operator's fingers (for example, the little finger, the ring finger, and the middle finger) to hold the gripping handle 5. The present application does not limit the specific value of the preset distance.

[0072] In one embodiment of the present application, Figure 6 As shown, the adjustment disk 32 of the present application may include a disk body 321 and a plurality of strip grooves 322 formed on the outer peripheral surface of the disk body 321, the strip grooves 322 extend along the axial direction of the disk body 321, and the plurality of strip grooves 322 are evenly spaced along the circumference of the disk body 321. In this way, the strip grooves 322 arranged in this way can make it easier for the operator to control the rotation of the adjustment disk 32 only with the thumb and index finger.

[0073] In one embodiment of the present application, Figures 6 to 9As shown, the take-up reel 4 of the present application may include a coaxially connected baffle portion 41 and a winding portion 42, wherein one end of the baffle portion 41 away from the winding portion 42 is connected to the operating rod 3, and the winding portion 42 includes a first end 421 and a second end 422 that are relatively arranged, the first end 421 is connected to the baffle portion 41, the radial dimension of the baffle portion 41 is larger than the radial dimension of the first end 421, and the radial dimension of the second end 422 is larger than the radial dimension of the first end 421; wherein, in the direction from the first end 421 to the second end 422, the radial dimension of the winding portion 42 gradually increases.

[0074] In this way, by configuring the wire take-up reel 4 in this way, the guide wire can be blocked by the baffle portion 41 when it is wound on the wire take-up reel 4, and close to the small end (i.e., the first end 421) of the winding portion 42, thereby effectively ensuring the winding stability of the guide wire on the wire take-up reel 4, effectively preventing the guide wire from escaping from the wire take-up reel 4, ensuring the winding stability and reliability of the guide wire, and effectively preventing the guide wire from becoming tangled or entangled with other components in the accommodating cavity 101.

[0075] In one embodiment of the present application, Figure 2 , Figure 8 and Fig. 9 As shown, the guide wire receiver 100 of the present application may also include a plurality of guide wire assemblies 6 disposed in the accommodating cavity 101, wherein the plurality of guide wire assemblies 6 are spaced apart along the circumference of the cover body 1, and the guide wire assemblies 6 include a limiting rod 61 and a wire pushing rod 62; the limiting rod 61 includes an installation portion 611 and a limiting portion 612 that are connected to each other, and the installation portion 611 is connected to the cover body 1 at one end away from the limiting portion 612, and the limiting portion 612 is arranged parallel to the outer circumferential surface of the winding portion 42; the wire pushing rod 62 is arranged between the limiting rod 61 and the winding portion 42, one end of the wire pushing rod 62 is connected to the box body 2, and the other end of the wire pushing rod 62 can be freely telescopically pointed to the baffle portion 41; wherein, the spacing between the limiting portion 612 and the winding portion 42 is configured to be greater than one diameter of the guide wire and less than two diameters of the guide wire.

[0076] In this way, by means of the limit rod 61 thus arranged, it is possible to effectively ensure that the winding thickness of the guide wire on the winding part 42 is a single layer, which can not only effectively avoid the problem of the guide wire being tangled or entangled with other components during the winding and secondary unwinding processes, but also effectively avoid the problem of multiple turns of the guide wire overlapping, thereby ensuring that the guide wire can be quickly and reliably and thoroughly disinfected.

[0077] At the same time, by configuring the wire pushing rod 62 in this way, it can be ensured that the guide wire is always closely attached to the baffle portion 41 and wound around the winding portion 42 during the winding process, which can effectively prevent the guide wire from becoming tangled or entangled with other components during the winding process.

[0078] In one embodiment of the present application, Figure 2 , Figures 9 to 11 As shown, the wire pushing rod 62 of the present application may include a pushing head 621, an elastomer 622 and a mounting tube 623, wherein a receiving chamber 6231 for accommodating the elastomer 622 is formed in the mounting tube 623, one end of the mounting tube 623 is connected to the box body 2, and the other end of the mounting tube 623 is provided with a limiting through hole 6232 which is interconnected with the receiving chamber 6231; the elastomer 622 is arranged in the receiving chamber 6231; the pushing head 621 includes a pushing block 6211, a connecting rod 6212 and a limiting block 6213, the connecting rod 6212 is passed through the limiting through hole 6232, and the two ends of the connecting rod 6212 are respectively connected to the pushing block 6211 and the limiting block 6213, the limiting block 6213 is arranged in the receiving chamber 6231 and is connected to the elastomer 622, the radial dimension of the limiting block 6213 is larger than the radial dimension of the limiting through hole 6232, and the pushing block 6211 is used to resist the guide wire.

[0079] In this way, the wire pushing rod 62 set up in this way can automatically press against the guide wire and reliably and effectively ensure that the wire pushing rod 62 always pushes the guide wire toward the baffle part 41, thereby ensuring the tightness of the guide wire winding and avoiding the problem of the guide wire getting tangled or entangled with other components during the winding or unwinding process.

[0080] In this embodiment, the pushing head 621 directly contacts the guide wire, thereby pushing the guide wire toward the baffle portion 41; the elastomer 622 provides a power source for the pushing head 621, ensuring that the pushing head 621 always presses against the guide wire; the mounting tube 623 limits the displacement of the pushing head 621, installs the push rod 62, and installs and protects the elastomer 622.

[0081] In addition, it can be understood that the elastomer 622 of the present application can have a variety of optional implementations. For example, the elastomer 622 can be a spring, a silicone elastic part, a plastic elastic part, a spring, etc., and the present application does not make specific limitations on this.

[0082] In one embodiment of the present application, Fig.10 As shown, the push block 6211 of the present application includes an end thereof away from the connecting rod 6212 and formed with a wedge-shaped surface 6211a inclined downward, and the wedge-shaped surface 6211a includes a first edge 6211b close to the winding portion 42 and a second edge 6211c away from the winding portion 42. In the direction from the first edge 6211b to the second edge 6211c, the axial length of the push block 6211 gradually increases.

[0083] Like this, by so setting the push block 6211, can effectively ensure that the guide wire is not only pushed toward the baffle part 41, but also can effectively ensure that the guide wire is pushed toward the winding part 42, thereby just can effectively ensure that the guide wire is tightly wound on the take-up drum 4 in a single layer form.

[0084] In one embodiment of the present application, Figure 4 , Figure 5 and Fig. 9 As shown, the guide wire receiver 100 of the present application may further include a wire management assembly 7 disposed in the accommodating chamber 101, the wire management assembly 7 including a wire management rod 71 and a wire passing ring 72 connected to each other, one end of the wire management rod 71 is connected to the cover body 1, and the wire passing ring 72 is disposed near the second end 422 and is located between the outlet through hole 21 and the winding portion 42.

[0085] In this way, the wire ring 72 can serve as a limiting structure for the guide wire to effectively control the position of the guide wire when passing through the lead-out hole 21 into and out of the accommodating chamber 101 to be closer to the large end (i.e., the second end 422) of the winding part 42. In this way, during the process of the wire taking-up drum 4 rotating to reel in the guide wire, the wire management assembly 7 can cooperate with the wire pushing rod 62, so that the guide wire is first wound around the large end of the winding part 42 and, under the action of the wire pushing rod 62, is closely close to the guide wire wound in the previous circle (or closely fits the baffle part 41).

[0086] When using the above-mentioned guide wire receiver 100 to disinfect the rolled guide wire, it is necessary to first invert the guide wire receiver 100 (this inversion is relative to the use state of the guide wire receiver 100) so that the outlet through hole 21 faces upward, and then inject disinfectant into the accommodating cavity 101 through the outlet through hole 21 for immersion disinfection. After the disinfection is completed, the guide wire receiver 100 is placed upright to discharge the disinfectant with the help of the outlet through hole 21. In this process, not only is the inversion process inconvenient, but also the part of the guide wire exposed from the outlet through hole 21 may completely enter the accommodating cavity 101 under the action of gravity or other influencing factors, which is inconvenient for the subsequent use of the guide wire. In addition, the disinfectant in the accommodating cavity 101 may not be completely and quickly automatically discharged due to the effect of atmospheric pressure.

[0087] In view of this, in one embodiment of the present application, Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, the guide wire receiver 100 of the present application may further include an injection tube 8, which is connected to the top of the box body 2, and the injection tube 8 is interconnected with the accommodating cavity 101; and, the outlet through hole 21 is opened at the bottom of the box body 2.

[0088] Compared with the method of only providing the lead-out through hole 21, the guide wire receiver 100 of the present application does not need to be inverted and then upright when disinfection is required. The disinfectant can be directly injected into the accommodating cavity 101 using the injection tube 8, and the disinfectant can be discharged using the lead-out through hole 21 to perform flushing disinfection. Alternatively, the disinfectant can be injected into the accommodating cavity 101 using the injection tube 8, and then the guide wire can be pressed with a finger and the lead-out through hole 21 can be blocked to perform immersion disinfection.

[0089] That is to say, the guidewire receiver 100 of the present application can achieve the disinfection of the guidewire more conveniently and quickly, and at the same time, can effectively avoid the problem of the guidewire being completely retracted into the accommodating cavity 101. In addition, it is also conducive to the rapid and thorough discharge of the disinfectant.

[0090] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
