Description

Technical Field

[0001] This utility model relates to the technical field of endoscope rigid endoscope auxiliary equipment, and in particular to an easily adjustable fixed base for endoscope rigid endoscopes. Background Technology

[0002] Rigid endoscopes, as common medical devices, have a wide range of applications in the medical field. They mainly consist of an imaging system, an illumination system, and an insertion section. The endoscope itself is rigid and not easily bent. With its high-resolution images and stable performance, it plays a crucial role in the diagnosis and treatment of various diseases. In the field of surgery, rigid endoscopes are indispensable tools in minimally invasive procedures. For example, in laparoscopic surgery, doctors insert a rigid endoscope into the abdominal cavity through several small incisions in the patient's abdomen. Using the clear images it provides, doctors can accurately observe the morphology, location, and lesions of organs within the abdominal cavity, such as tumors and inflammations in organs like the liver, gallbladder, and pancreas. Doctors can perform surgical procedures, such as cholecystectomy and appendectomy, without performing major open surgery, by manipulating other surgical instruments through these small incisions, significantly reducing patient trauma and postoperative recovery time.

[0003] However, existing rigid endoscope mounting bases have many shortcomings. Most current mounting bases have limited adjustment methods, making it difficult to achieve flexible adjustment of the rigid endoscope in multiple dimensions and failing to meet the needs of different observation angles in complex surgical scenarios. In some surgeries, due to the inconvenience of adjusting the mounting base, doctors may need to spend extra time and effort to adjust the position and angle of the endoscope, which not only increases the operation time but may also affect the accuracy of the operation. Moreover, existing mounting bases are difficult to provide stable support after adjustment. During the operation, even slight shaking may cause image blurring, affecting the doctor's observation and judgment of the lesion site, and thus affecting the surgical outcome. In view of this, we propose an easily adjustable mounting base for rigid endoscopes. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable mounting base for a rigid endoscope includes a strong A-clamp, a multi-joint universal adjustment support rod, and a connecting ring for connecting the rigid endoscope housing. The two ends of the multi-joint universal adjustment support rod are respectively connected to the strong A-clamp and the connecting ring.

[0007] The multi-ball joint universal adjustment support rod includes five or more equidistant double-sided ball clamps and several rolling balls. Both ends of the double-sided ball clamps are provided with a first ball groove for connecting the rolling balls. Several rolling balls are sequentially rolled between the strong A-clamp and the first lower double-sided ball clamp, between several adjacent double-sided ball clamps, and between the first upper double-sided ball clamp and the connecting ring. Two adjacent double-sided ball clamps are arranged in a cross shape in the radial direction.

[0008] A pressure locking mechanism for adjusting the mechanical strength of the multi-ball joint universal adjustment support rod is fixedly installed above the high-strength A-clamp. The pressure locking mechanism includes a pressure driving source and a high-pressure hose. Each double-sided ball clamp is provided with a round hole. The high-pressure hose passes through the round holes on several double-sided ball clamps in sequence. The ball is composed of a ball body and a rubber ball sleeve. The rubber ball sleeve is fitted to the outer wall of the ball body. A spherical cavity is provided inside the ball body. The high-pressure hose is interconnected with the spherical cavities in several balls. Several vent holes are provided around the spherical cavities. The lower end of the high-pressure hose is connected to the pressure driving source.

[0009] Preferably, both the upper and lower ends of the sphere are provided with connection holes that communicate with the spherical cavity. Several vent pipes and several sealing plugs are fixedly installed on the outer wall of the high-pressure hose. Several vent pipes are respectively arranged in the spherical cavity of several spheres. Several vent holes for connecting the spherical cavity and the inner cavity of the high-pressure hose are provided around the vent pipes. Several sealing plugs on the outer wall of the high-pressure hose are respectively sealed and installed in two connection holes on several spheres.

[0010] Preferably, the pressurization drive source consists of an air cylinder, a screw, a corrugated air bladder, and a circular block. The end of the corrugated air bladder is fixedly connected to the lower end of the high-pressure hose. The air cylinder is fixedly installed above the strong A-clamp. The corrugated air bladder is filled and installed inside the air cylinder. The circular block is fitted to one end of the corrugated air bladder and is telescopically installed inside the air cylinder. The end of the screw is rotatably connected to the circular block. The screw and the air cylinder are threadedly connected. A drive element is fixedly installed at the beginning of the screw.

[0011] Preferably, a pressure detection device is fixedly installed on one side of the lower end of the high-pressure hose, the driving element is preferably a handwheel or a motor, and the pressure detection device is preferably a pressure gauge or a pressure sensor.

[0012] Preferably, a curved pipe is fixedly connected to one side of the air cylinder, and a first single-sided ball clamp for connecting a rolling ball is fixedly connected above the curved pipe. A plurality of second grooves are densely arranged on the inner wall of the second ball groove in the first single-sided ball clamp. A second single-sided ball clamp for connecting a rolling ball is fixedly connected below the connecting ring. A plurality of third grooves are densely arranged on the inner wall of the third ball groove in the second single-sided ball clamp. A plurality of first grooves are densely arranged on the inner wall of the first ball groove in the double-sided ball clamp.

[0013] Preferably, the outer diameter of the high-pressure hose is smaller than the inner diameter of the circular hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The adjustable mounting base for rigid endoscopes provided by this invention has the following significant advantages:

[0016] 1. Multi-dimensional Flexible Adjustment: The multi-joint universal adjustment support rod consists of five or more equidistant double-sided ball clamps and several rolling balls, with adjacent double-sided ball clamps arranged in a cross shape in the radial direction. This unique design allows the rigid endoscope to rotate flexibly in multiple dimensions, achieving vertical and horizontal rotation. In various medical scenarios such as surgery, ENT examinations, and urological surgeries, doctors can easily adjust the position and angle of the rigid endoscope according to actual needs, quickly obtaining the best observation angle. This greatly improves the flexibility and convenience of operation, avoiding the problems of prolonged operation time and compromised accuracy caused by the limited adjustment methods of existing fixed bases.

[0017] 2. Stable Support and Rapid Locking: The pressure locking mechanism provides stable support to the fixed base. Once adjusted to the appropriate position, the gas in the corrugated airbag is compressed into the high-pressure hose by the pressure drive source, and then injected into the spherical cavity of the ball, causing the rubber ball sleeve to expand and press against the corresponding groove, thereby quickly locking the connected double-sided ball clip, the first single-sided ball clip, or the second single-sided ball clip. This process is simple and quick, effectively avoiding image blurring caused by the shaking of the fixed base during surgery, ensuring that the doctor can always obtain a clear and stable image, improving the accuracy of observation and judgment of the lesion site, and thus improving the surgical outcome.

[0018] 3. Adaptable to different control needs: The drive element can be either a handwheel or a motor, and the air pressure detection device can be either a pressure gauge or a pressure sensor. For manual operation, a handwheel and a pressure gauge are selected, allowing doctors to control the pressurization based on experience. For automatic control, a motor and a pressure sensor are selected. The pressure sensor can monitor the air pressure in the high-pressure hose in real time and feed it back to the motor to achieve a precise automatic pressurization process. This diverse selection can meet the operating habits of different doctors and the needs of actual medical scenarios, further enhancing the practicality and applicability of the mounting base.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5 As shown, an adjustable mounting base for a rigid endoscope includes a strong A-clamp 1, a multi-joint universal adjustment support rod 2, and a connecting ring 4 for connecting the rigid endoscope housing. The two ends of the multi-joint universal adjustment support rod 2 are connected to the strong A-clamp 1 and the connecting ring 4, respectively.

[0027] The multi-joint universal adjustment support rod 2 includes five or more equidistantly arranged double-sided ball clamps 21 and several rolling balls 22. Both ends of the double-sided ball clamps 21 are provided with first ball grooves 212 for connecting the rolling balls 22. The several rolling balls 22 are sequentially rolled between the strong A-clamp 1 and the first lower double-sided ball clamp 21, between several adjacent double-sided ball clamps 21, and between the first upper double-sided ball clamp 21 and the connecting ring 4. The two adjacent double-sided ball clamps 21 are arranged in a cross shape in the radial direction. This arrangement allows the two double-sided ball clamps 21 to rotate in the vertical dual-axis direction and horizontally along the outer wall of the rolling balls 22, thereby realizing the flexible adjustment of the multi-joint universal adjustment support rod 2 in multiple dimensions. Through the squeezing force between the outer wall of the rolling balls 22 and the double-sided ball clamps 21, the rigid endoscope can be relatively stably supported, ensuring that the rigid endoscope remains stable during the adjustment process and for a certain period of time after adjustment.

[0028] A pressure locking mechanism 3 for adjusting the mechanical strength of the multi-ball joint universal adjustment support rod 2 is fixedly installed above the strong A-clamp 1. The pressure locking mechanism 3 includes a pressure driving source and a high-pressure hose 37. Each double-sided ball clamp 21 is provided with a round hole 211. The high-pressure hose 37 passes through the round holes 211 on several double-sided ball clamps 21 in sequence, and the outer diameter of the high-pressure hose 37 is smaller than the inner diameter of the round hole 211 to ensure that the high-pressure hose 37 can pass through smoothly without affecting the rotation of the double-sided ball clamp 21.

[0029] The rolling ball 22 is composed of a ball 221 and a rubber ball sleeve 225. The rubber ball sleeve 225 is fitted onto the outer wall of the ball 221. A spherical cavity 222 is provided inside the ball 221. The high-pressure hose 37 is connected to the spherical cavities 222 in several balls 221. Several vent holes 224 are provided around the spherical cavity 222. The lower end of the high-pressure hose 37 is connected to the pressure driving source.

[0030] Specifically, both the upper and lower ends of the sphere 221 are provided with connection holes 223 that communicate with the spherical cavity 222. Several vent pipes 371 and several sealing plugs 372 are fixedly installed on the outer wall of the high-pressure hose 37. The several vent pipes 371 are respectively arranged in the spherical cavity 222 of the several spheres 221. Several vent holes 3711 for connecting the spherical cavity 222 and the inner cavity of the high-pressure hose 37 are provided around the vent pipes 371. Several sealing plugs 372 on the outer wall of the high-pressure hose 37 are respectively sealed and installed in the two connection holes 223 on the several spheres 221 to ensure that the gas can smoothly enter the spherical cavity 222 from the high-pressure hose 37 without leakage.

[0031] A bent pipe 33 is fixedly connected to one side of the air pump 31. A first single-sided ball clamp 34 for connecting the ball 22 is fixedly connected above the bent pipe 33. Several second grooves 341 are densely arranged on the inner wall of the second ball groove in the first single-sided ball clamp 34. A second single-sided ball clamp 41 for connecting the ball 22 is fixedly connected below the connecting ring 4. Several third grooves 411 are densely arranged on the inner wall of the third ball groove in the second single-sided ball clamp 41. Several first grooves 213 are densely arranged on the inner wall of the first ball groove 212 in the double-sided ball clamp 21. The grooves are designed to provide better friction and locking effect when the rubber ball sleeve 225 is inflated, thereby enhancing the stability of the locking.

[0032] The pressurization drive source consists of an air cylinder 31, a screw 32, a corrugated air bag 38, and a round block 39. The end of the corrugated air bag 38 is fixedly connected to the lower end of the high-pressure hose 37. The air cylinder 31 is fixedly installed above the strong A-clamp 1. The corrugated air bag 38 is filled and installed in the air cylinder 31. The round block 39 is fitted to one end of the corrugated air bag 38 and is telescopically installed inside the air cylinder 31. The end of the screw 32 is rotatably connected to the round block 39. The screw 32 and the air cylinder 31 are threadedly connected. The head end of the screw 32 is fixedly installed with a drive element 35.

[0033] When it is necessary to lock the position of the multi-joint universal adjustment support rod 2, the drive element 35 drives the screw 32 to rotate. The screw 32 pushes the round block 39 to move inside the air cylinder 31, thereby compressing the corrugated air bag 38. The gas in the corrugated air bag 38 is compressed into the high-pressure hose 37, and then the high-pressure hose 37 fills the spherical cavities 222 of several balls 221 respectively. Since the spherical cavity 222 is provided with a vent hole 224, the gas enters the rubber ball sleeve 225 through the vent hole 224, causing it to expand and be squeezed into the first groove 213, the second groove 341 or the third groove 411, so that the connected double-sided ball clamp 21, the first single-sided ball clamp 34 or the second single-sided ball clamp 41 cannot rotate, thus achieving the purpose of locking.

[0034] A pressure detection device 36 is fixedly installed on one side of the lower end of the high-pressure hose 37. The driving element 35 is preferably a handwheel or a motor, and the pressure detection device 36 is preferably a pressure gauge or a pressure sensor. If the driving element 35 is a handwheel, the handwheel and the screw 32 are fixedly connected, and the pressure detection device 36 is a pressure gauge. The operator can control the pressurization process by turning the handwheel and observe the pressure change through the pressure gauge. If the driving element 35 is a motor, the pressure detection device 36 is a pressure sensor, and the pressure sensor and the motor are electrically connected through wires and connected to an external power source. The motor and the air cylinder 31 are fixedly connected, and the output end of the rotor in the motor is fixedly connected to the screw 32. In this case, the pressure sensor can monitor the pressure in the high-pressure hose 37 in real time and feed the signal back to the motor to realize automatic control of the pressurization process and ensure that the pressure is stable and appropriate when locked.
