Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a bronchoscope delivery device. Background Art

[0002] A bronchoscope delivery device is a key device for controlling the movement of a bronchoscope within the human body. It is usually equipped on a bronchoscope robot and can perform forward / backward movement, rotation, and bending operations on the endoscope tube of the bronchoscope through a precise mechanical structure. This device can replace the doctor's manual operation of the bronchoscope, achieving separation between doctors and patients, and is particularly suitable for the diagnosis and treatment needs of patients with infectious diseases and patients in different locations.

[0003] After retrieval, a Chinese patent with the publication number CN117503037A discloses a bronchoscope delivery device and method. The device includes a mounting base and a limit delivery mechanism, which can be mounted on the end joint of a bronchoscope robot through the mounting base, so that the bronchoscope can be rotated under the drive of the end joint. At the same time, the limit delivery mechanism can axially deliver the endoscope tube of the bronchoscope through the cooperation of a driving wheel and a driven wheel, so as to realize the forward / backward movement and rotation operations of the endoscope tube. Further, since the driving wheel drive assembly includes a dynamic torque sensor, the dynamic torque during the forward / backward movement of the endoscope tube can be measured. Since the driven wheel moving assembly includes a static torque sensor, the static torque during the clamping or loosening of the endoscope tube can be measured. Thus, useful feedback information can also be provided to the doctor during the operation to help the doctor better operate the bronchoscope and reduce the risk of the operation. However, when this solution is actually used, there are still the following deficiencies:

[0004] When the bronchoscope is delivered, it needs to enter through the patient's nasal cavity. If the delivery angle cannot be ensured correctly, it is likely to cause discomfort to the patient. Existing devices often control the delivery path by being held by medical staff. It is difficult for medical staff to precisely control the entry angle of the bronchoscope only by hand-held, and even a slight deviation may cause unnecessary irritation or pain to the patient. On the other hand, hand-held operation requires high skills and experience of medical staff, and it is easy to cause fatigue when maintaining a specific posture for a long time, affecting the stability and accuracy of the operation. The above-mentioned device cannot control the angle of the bronchoscope entering the human body, which is likely to cause discomfort to the patient. Moreover, the above device only delivers by controlling the tube body, and it is difficult to ensure the overall stability of the test tube mirror. It still requires medical staff to assist in supporting the bronchoscope to make it present an appropriate angle with the device to ensure smooth delivery, resulting in inconvenient use, not only increasing the workload of medical staff but also reducing the efficiency of diagnosis and treatment.

[0005] Therefore, the present application provides a bronchoscope delivery device to meet the need for automatic delivery of the bronchoscope without assistance. Summary of the Invention

[0072] As Figures 1 to 9 shown, a bronchoscope delivery device includes a U-shaped frame 1; a first servo motor 2 fixedly installed on the top of the U-shaped frame 1; a lead screw 3 rotatably installed on the U-shaped frame 1 and fixedly connected to one end of the output end of the first servo motor 2 passing through the U-shaped frame 1; a slider 31 threadedly sleeved on the lead screw 3; a through hole 32 opened on the slider 31; a rotating tube 33 arranged at the bottom of the slider 31 and coaxially arranged with the through hole 32; a controller 35 arranged on the top of the slider 31; a bronchoscope 34 fixedly installed on the controller 35 and passing through the rotating tube 33; a torsion assembly arranged between the slider 31 and the rotating tube 33; a clamping assembly arranged on the rotating tube 33; a guiding assembly arranged on the U-shaped frame 1; the torsion assembly includes: an installation groove 4 opened at one end of the slider 31 close to the rotating tube 33 and adapted to the rotating tube 33, and the rotating tube 33 is rotatably connected in the installation groove 4; a slotted opening 41 opened at one end of the rotating tube 33 close to the slider 31; a plurality of teeth 42 fixedly installed in the slotted opening 41 and distributed in a circular array; a second servo motor 43 fixedly installed on the top wall of the installation groove 4; a rotating shaft 44 fixedly installed on the output end of the second servo motor 43; a worm 45 fixedly sleeved on the rotating shaft 44 and meshing with the teeth 42; an installation frame 8 is fixedly installed on the U-shaped frame 1;

[0073] When in use, the bronchoscope 34 is inserted into the through hole 32 and the rotating tube 33, the bronchoscope 34 is fixed by the clamping assembly, the other end of the bronchoscope 34 is placed in the guide assembly, and the lead screw 3 is driven to rotate by the servo motor 1 2, so that the slider 31 can move up and down under the action of the U-shaped frame 1, and the bronchoscope 34 is transported. When rotation is required, the servo motor 2 43 is started to drive the rotating shaft 44 to rotate, and the rotating shaft 44 then drives the worm 45 to rotate, and the worm 45 further drives the rotating tube 33 to rotate relative to the slider 31 through the teeth 42 to achieve the twisting of the bronchoscope 34. Through the gear ratio of the worm 45 and the teeth 42, high-precision angle control can be achieved, so as to better realize the surgical operation, which is beneficial to the operation, and the worm 45 can play a self-locking role, so as to improve the stability of the system. By fixing the device on the operating table or other positions and controlling the transportation of the bronchoscope 34, fully automatic transportation can be achieved, without the need for manual support or assistance from medical staff, thereby simplifying the use operation.

[0074] like Figure 2 and Figure 4 As shown, the clamping assembly includes: two slide grooves 5, which are symmetrically arranged on the inner wall of the rotating tube 33; two slide plates 51, which are respectively slidably installed in the two slide grooves 5; two groups of return springs 52, which are respectively fixedly installed between the two groups of slide plates 51 and the slide grooves 5; two guide grooves 53, which are symmetrically arranged on the outer wall of the rotating tube 33 and correspond to the slide grooves 5; two sliding plates 54, which are respectively slidably installed in the two guide grooves 53; wherein, the positions of the sliding plates 54 corresponding to the slide plates 51 are provided with fillets, and the sum of the overlapping distance between the sliding plates 54 and the rotating tube 33 and the width of the slide plates 51 is greater than the radius of the rotating tube 33; a flexible pad 55 is fixedly installed at one end of the slide plate 51 away from the sliding plate 54;

[0075] When installing the bronchoscope 34, first insert the bronchoscope 34 into the rotating tube 33, and by toggling the sliding plate 54, the rounded corner of the sliding plate 54 contacts the slide plate 51, and the slide plate 51 is pushed outward, and the slide plate 51 slides outward and clamps the bronchoscope 34. When the rotating tube 33 rotates, the limiting effect of the slide groove 5 on the slide plate 51 enables the system to stably clamp the bronchoscope 34. A flexible pad 55 is arranged on the slide plate 51. On the one hand, it can increase the friction of clamping, improve the stability of clamping and ensure the safety of use. On the other hand, the flexible pad 55 can protect the bronchoscope 34, avoid the bronchoscope 34 from being damaged by clamping, and protect the health and service life of the equipment. After the operation is completed, the sliding plate 54 is reset by toggling, and the slider 31 can be retracted under the action of the reset spring 52. At this time, the bronchoscope 34 can be taken out for cleaning and disinfection, and it is convenient for storage.

[0076] like Figures 7 to 9As shown, the guide device includes: a fixed frame 6, which is hinged at one end of the U-shaped frame 1 away from the servo motor 2; a guide tube 61, one end of which is fixedly installed on the fixed frame 6; a plurality of friction reduction components, which are evenly arranged in the guide tube 61; a cleaning component, which is arranged at one end of the guide tube 61 away from the fixed frame 6; the guide tube 61 is a metal shaped hose; the friction reduction component includes: a T-slot 62, which is opened on the inner wall of the guide tube 61; a T-block 63, which is slidably installed in the T-slot 62; a rolling bearing 64, which is rotatably installed at one end of the T-block 63 close to the inner side of the guide tube 61; a buffer spring 65, which is fixedly installed between the T-slot 62 and the T-block 63;

[0077] When the bronchoscope 34 passes through the guide tube 61, it changes direction under the guidance of the guide tube 61, and after the outlet end of the guide tube 61 is placed at a suitable angle, the bronchoscope 34 can stably maintain the angle of entry into the human body under the action of the guide tube 61, thereby reducing the discomfort of the patient caused by the change of the entry angle of the bronchoscope 34 or the inappropriate angle. The guide tube 61 is made of a metal shaped hose, so that its shape and angle can be easily adjusted, which is more convenient to control the angle of the bronchoscope 34. It is also more convenient for medical staff to use, improves the safety of the device during use, and increases the applicability of the equipment. The bronchoscope 34 is inside the guide tube 61 and contacts with the rolling bearing 64. The friction is reduced under the action of the rolling bearing 64, making the transportation smoother, and the position of the rolling bearing 64 can be changed accordingly according to the state of the bronchoscope 34 through the action of the buffer spring 65, thereby improving the stability and practicality of the equipment.

[0078] like Figures 6 to 8 As shown, the cleaning assembly includes: a cleaning box 7, which is arranged at one end of the guide tube 61 away from the fixing frame 6; a clearance opening 71, which is opened on the cleaning box 7 and is larger than the inner diameter of the guide tube 61; two sponge pads 72, which are fixedly installed in the cleaning box 7, and a circular hole smaller than the bronchoscope 34 is opened in the center; a fixing ring 73, which is fixedly installed between the sponge pads 72, and a circular hole of the same size as the clearance opening 71 is opened in the center; a plurality of bristles 74, which are evenly fixedly installed on the inner side wall of the fixing ring 73; a magnetic ring 75 is fixedly installed at one end of the guide tube 61 away from the fixing frame 6, and the cleaning box 7 is made of magnetic material;

[0079] During use, the cleaning box 7 is connected to the magnetic ring 75 by magnetic attraction. When the bronchoscope 34 is input, the bronchoscope 34 can pass through the cleaning component smoothly because the clearance port 71 is larger than the tube diameter. After the operation is over, when the bronchoscope 34 is recovered, the sponge pad 72 and the bristles 74 are passed in turn to remove the substances and liquids on the bronchoscope 34. When the bronchoscope 34 enters the human body, it is at a horizontal angle. At this time, the cleaning box 7 can collect the cleaned substances in the box body to avoid cross contamination. The magnetic connection method can simplify the installation operation and reduce the use cost of the disposable cleaning box 7. The sponge pad 72 can store disinfecting liquids such as alcohol, which can perform preliminary disinfection and cleaning on the bronchoscope 34 to avoid the spread of pollution.

[0080] The technical solution provided by the present invention is to insert the bronchoscope 34 into the through hole 32 and the rotating tube 33, fix the bronchoscope 34 by the clamping assembly, put the other end of the bronchoscope 34 into the guide assembly, and drive the screw 3 to rotate by the servo motor 1 2, so that the slider 31 can move up and down under the action of the U-shaped frame 1, and realize the transportation of the bronchoscope 34. When rotation is required, the servo motor 2 43 is started to drive the rotating shaft 44 to rotate, and the rotating shaft 44 then drives the worm 45 to rotate, and the worm 45 further drives the rotating tube 33 to rotate relative to the slider 31 through the teeth 42 to realize the twisting of the bronchoscope 34. Through the gear ratio of the worm 45 and the teeth 42, high-precision angle control can be achieved, so as to better realize the surgical operation, which is beneficial to the operation, and the worm 45 can play a self-locking role, so as to improve the stability of the system. By fixing the device on the operating table or other positions and controlling the transportation of the bronchoscope 34, fully automatic transportation can be achieved without the need for manual support or assistance from medical staff, thereby simplifying the use operation.
