Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an auxiliary device for urinary calculi soft endoscope surgery. Background Art

[0002] Ureteroscopic lithotripsy is a common surgical method for the treatment of kidney stones, and its operation is delicate and complicated. During the operation, the doctor needs to insert the ureteroscope through the urethra and accurately navigate to the lesion area. Subsequently, a guide wire is left in place and guided along it to accurately place the outer sheath of the ureteroscope at the location of the stone. However, due to the large volume of such soft ureteroscope surgeries, doctors need to stand for a long time and hold the scope steadily, which is not only a great test for the doctor's physical fitness, but also may cause health problems such as wrist arthritis, excessive fatigue and varicose veins. The accumulation of these problems will undoubtedly pose a potential threat to the safety of the operation. At present, there is still a lack of auxiliary devices specifically for such operations in clinical practice. The existing ordinary stools can provide certain support, but their defects are also obvious: they do not have a hand support panel device specially designed for ureteroscopic surgery, and cannot effectively reduce the burden on the doctor's hands; the stools need to be manually raised and lowered, which is quite inconvenient to operate; at the same time, they also lack a clamping device for fixing the soft mirror optical fiber, which undoubtedly increases the uncertainty during the operation. Therefore, how to develop a device that can effectively assist ureteroscopic surgery to reduce the physical burden of doctors during long-term surgery and reduce safety risks is an urgent problem that needs to be solved.

In addition, it should be understood that any embodiments described in this application and the technical features included therein can be combined with each other.

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figure 1-7 As shown, an auxiliary device for urinary calculi soft endoscope surgery comprises a mobile base 1, a liftable seat 2 slidably arranged on the mobile base 1, and an upper limb auxiliary device 3 fixed on the mobile base 1. The liftable seat 2 and the upper limb auxiliary device 3 are arranged along the longitudinal direction of the mobile base 1. The liftable seat 2 is slidably arranged on the mobile base 1 to adjust the distance between the liftable seat 2 and the upper limb auxiliary device 3, so that the doctor's body position is adjusted to the most comfortable position for surgical operation; the upper limb auxiliary device 3 comprises a first telescopic rod 301 fixed to the mobile base 1 and a cross bar 302 rotatably arranged on the top of the first telescopic rod 301, one end of the cross bar 302 is rotatably connected to a support for supporting The first supporting mechanism 303 for holding the hand holding the telescope, the other end of the crossbar 302 is rotatably connected to the second supporting mechanism 304 for supporting the idle hand; a control mechanism 4 is fixed on one side of the liftable seat 2, and the control mechanism 4 is used to control the lifting and sliding of the liftable seat 2, the lifting and sliding of the first telescopic rod 301 and the adjustment of the telescope, and the lifting and sliding of the liftable seat 2 and the lifting and sliding of the first telescopic rod 301 are respectively adjusted by the control mechanism 4, so that the hand holding the telescope and the idle hand are supported on the first supporting mechanism 303 and the second supporting mechanism 304 respectively, and the positions of the first supporting mechanism 303 and the second supporting mechanism 304 are rotated to adjust, so that the hand holding the telescope faces the operating area 5. The operating area 5 refers to the position between the two legs when the patient lies flat on the operating bed. The longitudinal direction is X, the transverse direction is Y, and the auxiliary device moves to the tail end of the operating bed, so that the upper limb auxiliary device 3 is close to the patient's legs. The lifting method of the first telescopic rod 301 can be mechanical transmission or hydraulic. The first supporting mechanism 303, the second supporting mechanism 304 and the liftable seat 2 may all be covered with sterile cloth, thereby ensuring that the entire device meets the requirements of aseptic operation.

[0033] like Figure 1 , 3As shown in Figure 6, the first supporting mechanism 303 includes a first supporting plate 303a, the upper part of the first supporting plate 303a has a concave portion 303b, the concave portion 303b cooperates with the forearm of the hand holding the telescope, and the rear end of the first supporting plate 303a is vertically provided with a second supporting plate 303c for supporting the elbow, and the bottom of the first supporting plate 303a is rotatably connected to one end of the crossbar 302. Among them, there is a sponge pad on the concave portion 303b to further reduce the discomfort of the hand holding the telescope when it is fixed for a long time. Since the forearm needs to be bent to operate the hand holding the telescope, the forearm and the upper arm are fixed in a V shape to hold the telescope hand, therefore, the design of the first supporting plate 303a and the second supporting plate 303c can well support the doctor's forearm and elbow, fit the shape of the doctor's hand holding the telescope, reduce muscle fatigue for a long time, and improve the safety of the operation.

[0034] like Figure 6 As shown, the bottom of the first supporting plate 303a has a rotating mounting arm 305, and the first supporting plate 303a is rotatably connected to one end of the cross bar 302 through the rotating mounting arm 305. The rotating mounting arm 305 includes a base 305a, a rotating joint 305b and a connecting rod 305c arranged in series, the base 305a is rotatably connected to one end of the cross bar 302, and the connecting rod 305c is fixedly connected to the bottom of the first supporting plate 303a, and the connecting rod 305c is swung back and forth relative to the base 305a through the rotating joint 305b. Among them, the base 305a rotates freely on the cross bar 302, thereby driving the entire rotating mounting arm 305 and the first supporting plate 303a to rotate together. Through the rotating joint 305b, the connecting rod 305c can swing back and forth relative to the base 305a, which not only allows the first supporting plate 303a to rotate in the horizontal direction, but also can be fine-tuned in the vertical direction, thereby achieving accurate support for the forearm of the hand holding the soft lens. Of course, the rotating mounting arm 305 is only one of the movable structures. It is understandable that any movable structure having the same function as the rotating mounting arm 305 can be applied to the connection between the first supporting plate 303a and the cross bar 302.

[0035] like Figure 1 , 3As shown in FIG. 7 , the second supporting mechanism 304 includes a third supporting plate 304a, and a clamp 304b for clamping a soft mirror guide wire is provided on the third supporting plate 304a, and the bottom of the third supporting plate 304a is rotatably connected to the other end of the crossbar 302. Wherein, the third supporting plate 304a is a flat plate, used to support the idle hand, generally the idle hand is in a horizontal position, and the idle hand can be placed flat on the flat plate, and the size of the flat plate is 30-80mm in length and 30-80mm in width. In this embodiment, the size of the flat plate is 60*40mm. Wherein, a sponge pad is provided on the third supporting plate 304a to further reduce the discomfort of the idle hand in a state of being fixed for a long time. Wherein, the clamp 304b includes a clamping part and a connecting rod, the connecting rod is fixedly connected to the clamping part, and the bottom of the connecting rod is fixedly connected to the third supporting plate 304a, and the connecting rod can have telescopic and flexible functions, so that the clamping part can adjust the clamping direction / angle at will, which is convenient for the doctor to operate. The soft endoscope guide wire is an important tool for guiding the soft endoscope into the urethra and urinary system. The clamp 304b is fixed on the third support plate 304a. Through its clamping function, it can stably fix the soft endoscope guide wire and optical fiber to ensure accurate guidance and stable operation of the soft endoscope during surgery. This helps doctors better observe the surgical area 5, improves the accuracy and safety of the surgery, and can also prevent related surgical instruments from falling and reduce surgical assistants.

[0036] like Figure 7 As shown, the bottom of the third support plate 304a has a rotating mounting arm 305, and the third support plate 304a is rotatably connected to the other end of the cross bar 302 through the rotating mounting arm 305. The rotating mounting arm 305 includes a base 305a, a rotating joint 305b and a connecting rod 305c arranged in series, the base 305a is rotatably connected to the other end of the cross bar 302, and the connecting rod 305c is fixedly connected to the bottom of the third support plate 304a, and the connecting rod 305c is swung back and forth relative to the base 305a through the rotating joint 305b. Among them, the base 305a rotates on the cross bar 302, thereby driving the entire rotating mounting arm 305 and the first support plate 303a to rotate together. Through the rotating joint 305b, the connecting rod 305c can swing back and forth relative to the base 305a. Such an arrangement not only allows the third support plate 304a to rotate in the horizontal direction, but also allows fine adjustment in the vertical direction, thereby achieving accurate support for the forearm of the hand holding the soft lens. Of course, the rotating mounting arm 305 is only one of the movable structures. It can be understood that any movable structure having the same function as the rotating mounting arm 305 can be applied to the connection between the first supporting plate 303a and the cross bar 302.

[0037] like Figure 1 and 4As shown, the liftable chair 2 includes a chair body 201, a second telescopic rod 202 fixed at the bottom of the chair body 201, and a bearing plate 203 fixed at the lower part of the second telescopic rod 202. The bottom of the second telescopic rod 202 is slidably connected to the mobile base 1. The bearing plate 203 has a rotatable foot pedal 203a. The rotatable foot pedal 203a is arranged opposite to the chair body 201 and is used to support the operator's feet. The bottom of the rotatable foot pedal 203a has a fixed support rod 306. One end of the fixed support rod 306 is fixedly connected to the bearing plate 203, and the other end of the fixed support rod 306 is rotatably connected to the bottom of the rotatable foot pedal 203a, so that the rotatable foot pedal 203a can swing back and forth in the longitudinal direction to adjust the supporting angle of the foot. The rotation mode can be electric or mechanical transmission. The control mechanism 4 is located on the bearing plate 203, and the control mechanism 4 moves with the movement of the liftable chair 2, which is convenient for the operator to control. Among them, the lifting mode of the second telescopic rod 202 can be mechanical transmission or hydraulic.

[0038] like Figure 1 and 5 As shown, the bottom sides of the second telescopic rod 202 are provided with a plurality of rollers 202a, the mobile base 1 is provided with a strip groove 101 along the longitudinal direction, and the two sides of the strip groove 101 are provided with inner grooves 102, and the rollers 202a are slidably sleeved in the inner grooves 102. Among them, the plurality of rollers 202a on the two sides of the bottom of the second telescopic rod 202 are arranged side by side, and the rollers 202a slide in the inner grooves 102, so that the second telescopic rod 202 can slide smoothly on the mobile base 1. The design of the rollers 202a reduces friction, making the lifting and sliding process of the liftable seat 2 smoother, and reducing the difficulty and resistance of operation.

[0039] like Figure 1 and 4As shown, the control mechanism 4 includes a shell 401 with one side open, a power switch 402 is provided on the top of the shell 401, and the interior of the shell 401 has a plurality of electric pedals 403 for controlling the lifting and sliding of the liftable seat 2, the lifting and sliding of the first telescopic rod 301, and the adjustment of the soft mirror. The power switch 402, the liftable seat 2, the upper limb assistive device 3 and the soft mirror are respectively connected to the electric pedal 403 circuit. Among them, the power switch 402 is responsible for controlling the on and off of the entire circuit, and the electric pedal 403 specifically controls the first telescopic rod 301, the second telescopic rod 202, the roller 202a and the soft mirror. The first telescopic rod 301, the second telescopic rod 202, the roller 202a and the soft mirror are collectively referred to as actuators. Each electric pedal 403 is connected to the corresponding actuator through a circuit. When the corresponding electric pedal 403 is stepped on, an electrical signal will be sent to the corresponding actuator, thereby driving the actuator to perform corresponding actions, such as the lifting and lowering of the first telescopic rod 301, the lifting and lowering of the second telescopic rod 202, the rotation of the roller 202a, and the laser, focal length, light, image, etc. of the soft mirror. The control mechanism 4 enables the doctor to conveniently and quickly adjust the state of the surgical auxiliary device during the operation, thereby improving the efficiency and accuracy of the operation.

[0040] like Figure 3 As shown, a support rod 306 is also provided at the bottom of the crossbar 302, and a slot 301a is correspondingly provided at the top of the first telescopic rod 301, and the support rod 306 can be rotatably inserted in the slot 301a, and holes 301b are relatively provided on both sides of the slot 301a, and a through hole 306a is correspondingly provided on the side of the support rod 306, and the hole 301b is fixedly connected with the through hole 306a through the insertion rod 307. Specifically, the two insertion holes 301b of the slot 301a are arranged left and right along the horizontal direction of the mobile base 1, and when the insertion rod 307 passes through the insertion hole 301b and the through hole 306a to complete the fixation, the crossbar 302 is parallel to the horizontal direction of the mobile base 1; when it is necessary to switch the soft lens holding hand, it is only necessary to pull out the insertion rod 307 and rotate the crossbar 302 180 degrees, so that the positions of the first supporting mechanism 303 and the second supporting mechanism 304 are interchanged, so as to realize the switching of the supporting soft lens holding hand, which greatly improves the flexibility and efficiency of the operation.

[0041] like Figure 1 As shown, the bottom of the mobile base 1 has a plurality of pulleys 103. Among them, the bottom of the mobile base 1 has four pulleys 103, and the four pulleys 103 are respectively arranged at the four corners of the bottom of the mobile base 1. Before the operation, the doctor or nurse can quickly and conveniently move the mobile base 1 and the auxiliary device thereon to the operation position, which greatly improves the flexibility and efficiency of the operation. When not in use, it can be removed, which is convenient and quick.

[0042] like Figure 1 and 2As shown, the front side of the mobile base 1 also has a cleaning bucket for cleaning surgical debris, and the front end of the mobile base 1 has a concave arc surface 104 for matching with the cleaning bucket. The cleaning bucket is located below the surgical area 5, that is, between the patient's legs. The cleaning bucket matches the concave arc surface 104, so that the cleaning bucket is not easy to slip and tilt.

[0043] The working method of the utility model is as follows:

[0044] Before starting the operation, the doctor moves the auxiliary device to the operation area 5 according to the operation needs. Specifically, the mobile base 1 is moved between the patient's legs by the pulley 103, and the concave arc surface 104 on the front side of the mobile base 1 cooperates with the cleaning bucket.

[0045] The doctor sits on the liftable chair 2, and adjusts the lifting and sliding of the liftable chair 2 through the control mechanism 4 to adjust the doctor's height and the distance between the liftable chair 2 and the upper limb assistive device 3. Specifically, the doctor steps on the electric pedal 403 to drive the second telescopic rod 202 and the roller 202a to adjust the height of the chair body 201 and the distance between the chair body 201 and the upper limb assistive device 3 accordingly.

[0046] The doctor places the hand holding the soft mirror on the first supporting mechanism 303, and the idle hand on the second supporting mechanism 304, and adjusts the horizontal angle and vertical angle of the first supporting mechanism 303 and the second supporting mechanism 304 by rotating the mounting arm 305, so that the hand holding the soft mirror faces the surgical area 5. Specifically, the hand holding the soft mirror is placed in a V-shape on the first supporting plate 303a and the second supporting plate 303c, the forearm is placed on the first supporting plate 303a, the elbow is placed on the second supporting plate 303c, the hand holds the soft mirror, and the position of the hand holding the soft mirror is adjusted by rotating the mounting arm 305 in the horizontal and vertical directions, the idle hand is placed horizontally on the third supporting plate 304a, the clamp 304b clamps the guide wire optical fiber, and the guide wire optical fiber enters the surgical position of the patient through the soft mirror.

[0047] In general, the auxiliary device for urinary calculi soft endoscope surgery of the utility model comprises a mobile base, a liftable seat slidably arranged on the mobile base, and an upper limb auxiliary device fixed on the mobile base. The auxiliary device integrates mobility, adjustability, limb support and multi-function control. Through humanized design and stable and durable structure, it effectively reduces the limb burden of doctors during surgery and improves operation efficiency. The utility model can be easily moved in the operating room by equipping the upper limb auxiliary device and the liftable seat on the mobile base, and the position of the seat and the upper limb auxiliary device can be accurately adjusted according to the surgical requirements, providing great flexibility and convenience. The liftable seat of the utility model can avoid the doctor's legs standing for a long time and reduce varicose veins. The seat height can be adjusted according to the doctor's height and body shape, as well as the distance from the upper limb auxiliary device, to achieve the best surgical posture. The upper limb auxiliary device provides stable support for the doctor's soft endoscope hand and idle hand through the first supporting mechanism and the second supporting mechanism, which helps to reduce the limb burden caused by long-term surgical operations and prevent fatigue and hand discomfort. The first support plate, the second support plate and the third support plate are designed with ergonomics in mind, and can adapt well to the shape of the doctor's arm to provide comfortable support. At the same time, the addition of a rotating mounting arm allows the angle of the support plate to be flexibly adjusted to meet personalized needs. The control mechanism of the utility model moves with the liftable seat, allowing the doctor to easily control the lifting and sliding of the seat, as well as the extension and retraction of the upper limb assistive device and the adjustment of the soft mirror, thereby improving the efficiency and convenience of the surgical operation. The clamp of the utility model is fixed on the third support plate, which can not only firmly clamp the soft mirror guide wire and optical fiber, effectively preventing the accidental drop of surgical instruments, but also can reduce the dependence on other surgical assistants to a certain extent, thereby improving the fluency and safety of the operation.
