Description

Technical Field

[0001] The present invention relates to the technical field of anastomosis auxiliary clamps, in particular to a micro end-to-end anastomosis auxiliary clamp for vascular anastomosis. Background Art

[0002] In some cases, vascular anastomosis can be performed while the blood vessels are separated from the human body. For example, during a vascular transplant surgery, the blood vessels obtained from the donor need to be anastomosed with the recipient's blood vessels. At this time, the blood vessels are separated from the original donor's body and will be placed on the operating table using auxiliary clamps for the anastomosis operation.

[0003] Traditional clamps have relatively simple functions and often require medical staff to manually adjust the clamping distance. They cannot be quickly and flexibly adjusted according to the needs of blood vessels of different lengths and complex surgical scenarios. When facing special cases, the applicability of the clamps is poor, which in turn affects the efficiency and quality of the surgery. The anti-slip design of traditional clamps usually relies only on simple rubber pads or the weight of the clamp itself. During the operation, due to factors such as the doctor's operation and the patient's breathing, the clamp is prone to displacement, affecting the smooth progress of the operation.

[0004] Therefore, to address the problems that the above-mentioned clamp cannot be quickly and flexibly adjusted according to the requirements of blood vessels of different lengths and complex surgical scenarios, and the clamp's clamping stability is insufficient, a microscopic end-to-end anastomosis auxiliary clamp for vascular anastomosis can be designed. Summary of the Invention

[0005] In order to overcome the problem that traditional clamps cannot be quickly and flexibly adjusted according to the needs of blood vessels of different lengths and complex surgical scenarios, and the clamps lack stability.

[0006] The technical solution is as follows: A microscopic end-to-end anastomosis auxiliary clamp for vascular anastomosis, including a clamp base plate; the upper end of the clamp base plate is fixedly connected to a support platform, and the lower end of the clamp base plate is installed with a transverse telescopic mechanism for adjusting the clamping distance, and the side end of the support platform and the outer side of the transverse telescopic mechanism are both installed with adjustable clamping mechanisms, a lifting platform is installed on one side of the upper end of the clamp base plate, and a high-definition microscope is installed on the outer side of the lifting platform, and the interior of the transverse telescopic mechanism includes a protective cover installed at the lower end of the clamp base plate, and a telescopic cylinder located inside the protective cover is installed at the lower end of the clamp base plate, and a moving block is installed at the output end of the telescopic cylinder, and the upper end of the moving block is fixedly connected to a limiting slider, and the upper end of the limiting slider is fixedly connected to a telescopic adjustment plate.

[0007] Furthermore, anti-slip support pads are fixedly connected to the four corners of the lower end of the clamp base plate. A limiting slide groove is opened inside the clamp base plate for use with the limiting slider, and a storage groove is opened inside the support platform to facilitate the sliding of the telescopic adjustment plate.

[0008] Furthermore, the adjustable clamping mechanism includes a control panel installed on one side of the support platform, an adjustment cavity is opened inside the control panel, a rotating knob is installed on one side of the control panel, and a protective block is fixedly connected to the upper end of the control panel.

[0009] Furthermore, a bidirectional adjustment screw is installed on the side end of the rotating button, a fixed stop is installed inside the adjustment cavity at the center of the bidirectional adjustment screw, first bearings are installed on both sides of the inner wall of the adjustment cavity, and the bidirectional adjustment screw is rotatably installed on the inner walls of the two first bearings.

[0010] Furthermore, the outer side of the bidirectional adjustment screw is threadedly connected to two groups of oppositely arranged threaded sleeves, the upper end of the threaded sleeve is fixedly connected to a vertical support rod, and the outer threads of the bidirectional adjustment screw on both sides of the center are opposite to each other, and the two threaded sleeves are respectively adapted to the two types of threaded sleeves.

[0011] Furthermore, the side ends of the vertical support rods are fixedly connected to the transverse support rods, and the side ends of the transverse support rods are installed with blood vessel clamping arc plates, which are specifically made of medical-grade stainless steel, titanium alloy or polyetheretherketone.

[0012] Furthermore, a through groove is provided through the center of the protection block, and a transverse inner groove is provided inside the protection block.

[0013] Furthermore, the lifting platform includes a support frame plate, a servo motor is installed at the center of the upper end of the support frame plate, a threaded rotating rod is installed at the output end of the servo motor, a second bearing is installed at the lower end of the threaded rotating rod, and a lifting sleeve is threadedly connected to the outer side of the threaded rotating rod.

[0014] Furthermore, a guide vertical rod is provided through the interior of the lifting sleeve at both ends of the outer side of the threaded rotating rod, and an adjustable mounting bracket connected to the high-definition microscope is installed on the side end of the lifting sleeve.

[0015] The beneficial effects are as follows: the adjustable clamping mechanism of the present invention can achieve precise clamping of blood vessels according to the thickness and shape of the blood vessels, which can not only firmly fix the blood vessels but also avoid excessive compression or damage to the blood vessels, thereby helping to improve the success rate of surgery and the healing effect of blood vessels; the telescopic cylinder can drive the moving block to move, so that the limit slider can drive the telescopic adjustment plate to move laterally, thereby achieving precise adjustment of the blood vessel clamping distance, so that the two ends of the blood vessel can be better aligned during the vascular anastomosis process, thereby improving the success rate of the anastomosis. Compared with traditional clamps that cannot be quickly and flexibly adjusted to meet the needs of different lengths of blood vessels and complex surgical scenarios, and the clamping stability is insufficient, the clamp of the present invention can not only flexibly adjust the clamping distance, but also use an adjustable clamping mechanism to achieve stable clamping. The use of a high-definition microscope can provide doctors with high-definition magnified images, allowing doctors to accurately observe the structure of the blood vessels and the anastomosis process at a microscopic level, thereby helping to improve the quality and success rate of vascular anastomosis and reduce the occurrence of surgical complications. At the same time, the use of a lifting platform allows doctors to adjust the high-definition microscope to the optimal observation position according to the needs of the surgical operation, obtain a clear surgical field of view, and help improve the precision and accuracy of the surgery.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1-Figure 7 As shown, a microscopic end-to-end anastomosis auxiliary clamp for vascular anastomosis comprises a clamp base plate 1; a support platform 2 is fixedly connected to the upper end of the clamp base plate 1, a transverse telescopic mechanism for adjusting the clamping distance is installed at the lower end of the clamp base plate 1, and an adjustable clamping mechanism is installed on the side end of the support platform 2 and the outer side of the transverse telescopic mechanism; a lifting platform 5 is installed on one side of the upper end of the clamp base plate 1, and a high-definition microscope 6 is installed on the outer side of the lifting platform 5; the interior of the transverse telescopic mechanism includes a protective cover 401 installed at the lower end of the clamp base plate 1, a telescopic cylinder 402 located inside the protective cover 401 is installed at the lower end of the clamp base plate 1, a moving block 403 is installed at the output end of the telescopic cylinder 402, the upper end of the moving block 403 is fixedly connected to a limiting slider 404, and the upper end of the limiting slider 404 is fixedly connected to a telescopic adjustment plate 405;

[0028] The fixture base plate 1 is made of high-strength aviation aluminum alloy, ensuring lightweight while having excellent load-bearing capacity. Its surface is anodized to form a dense oxide film, which not only enhances wear resistance and corrosion resistance, but also effectively resists the erosion of various disinfectants during surgery.

[0029] Protective cover 401 is made of transparent polycarbonate material with extremely high light transmittance. Medical staff can directly observe the operating status of key components such as the internal telescopic cylinder 402 through the cover without removing the cover, facilitating real-time monitoring and troubleshooting. Polycarbonate also has excellent impact resistance and chemical stability, effectively blocking contaminants such as blood and flushing fluid splashed during surgery, protecting internal precision components from corrosion, extending the service life of the clamp, and ensuring the long-term stable operation of the horizontal telescopic mechanism.

[0030] The four corners of the lower end of the clamp base 1 are fixedly connected with anti-slip support pads 101. The clamp base 1 is provided with a limit slide 406 for use with the limit slider 404. The support platform 2 is provided with a storage groove 201 for sliding the telescopic adjustment plate 405. The anti-slip support pad 101 is made of medical-grade silicone material, and its bottom is designed with a unique wavy texture, which can greatly increase the friction with the surface of the operating table, effectively preventing the clamp from sliding during surgery and ensuring the stability of the surgical operation.

[0031] The adjustable clamping mechanism includes a control panel 301 installed on one side of the support platform 2, an adjustment cavity 302 is provided inside the control panel 301, a rotating knob 303 is installed on one side of the control panel 301, and a protective block 304 is fixedly connected to the upper end of the control panel 301. The rotating knob 303 can be operated in two modes, manual or electric, to meet the needs of different surgical scenarios and the operating habits of doctors; in manual mode, the surface of the rotating knob 303 is designed with an anti-slip texture, and the doctor can control the bidirectional adjustment screw 305 by slightly turning his finger, and the operation feels comfortable and the control is precise; in electric mode, the doctor only needs to input the corresponding parameters on the control interface through the control system connected to the surgical console, and the rotating knob 303 can automatically and accurately adjust the rotation angle of the bidirectional adjustment screw 305 under the drive of the micromotor, so as to achieve fast and precise adjustment of the blood vessel clamping position. The electric mode also has a memory function, which can store commonly used adjustment parameters, which is convenient for quick call in similar operations, further improving surgical efficiency;

[0032] A bidirectional adjustment screw 305 is installed at the side end of the rotating knob 303, and a fixed stopper 306 is installed at the center of the bidirectional adjustment screw 305 inside the adjusting cavity 302. First bearings 307 are installed on both sides of the inner wall of the adjusting cavity 302, and the bidirectional adjustment screw 305 is rotatably installed on the inner walls of the two first bearings 307. The first bearings 307 are deep groove ball bearings, which have a low friction coefficient and high rotation accuracy. They are installed at both ends of the bidirectional adjustment screw 305, which can effectively reduce the friction torque when the screw rotates, making the rotation easier and smoother, while extending the service life of the screw.

[0033] The outer side of the bidirectional adjustment screw 305 is threadedly connected to two sets of oppositely arranged threaded sleeves 308. The upper ends of the threaded sleeves 308 are fixedly connected to the vertical support rod 309. The threads on the outer sides of the bidirectional adjustment screw 305 are opposite to each other, and the two threaded sleeves 308 are respectively adapted to the two types of threads. The length of the vertical support rod 309 can be adjusted accordingly according to design requirements.

[0034] The side ends of the vertical support rods 309 are fixedly connected to the transverse support rods 310, and the side ends of the transverse support rods 310 are installed with blood vessel clamping arc plates 311. The blood vessel clamping arc plates 311 are specifically made of medical-grade stainless steel, titanium alloy or polyetheretherketone. Medical-grade stainless steel has good corrosion resistance and mechanical strength and is easy to clean and disinfect; titanium alloy has excellent biocompatibility and corrosion resistance, is light in weight and high in strength; polyetheretherketone has excellent biocompatibility, mechanical properties and chemical corrosion resistance, and can be X-rayed, without affecting imaging examinations during surgery;

[0035] A through-groove 312 is formed at the center of the protective block 304, and a transverse inner through-groove 313 is formed inside the protective block 304. The through-groove 312 provides space for accommodating and protecting the blood vessel, while preventing excessive squeezing and damage to the blood vessel during the clamping process. At the same time, the through-groove 312 also serves as a guide, helping the doctor to more accurately place the blood vessel in the appropriate clamping position.

[0036] When the clamping distance needs to be adjusted, the telescopic cylinder 402 installed inside the protective outer cover 401 at the lower end of the clamp base plate 1 is started, and the output end of the telescopic cylinder 402 drives the moving block 403 to move. The moving block 403 can drive the limiting slider 404 to slide in the limiting slide groove 406 provided through the inside of the clamp base plate 1 to ensure the stability of the movement of the moving block 403. The telescopic adjustment plate 405 fixed on the upper end of the limiting slider 404 slides in the receiving groove 201 provided inside the support platform 2 to achieve the adjustment of the clamping distance;

[0037] Rotating the knob 303 mounted on one side of the adjustable clamping mechanism control plate 301 drives the bidirectional adjustment screw 305 mounted on the side of the knob 303 to rotate. A fixed block 306 is mounted at the center of the bidirectional adjustment screw 305, and first bearings 307 are mounted on both sides to ensure the stability of the bidirectional adjustment screw 305's rotation. Two sets of oppositely disposed threaded sleeves 308 are threadedly connected to the outer side of the bidirectional adjustment screw 305. As the bidirectional adjustment screw 305 rotates, the threaded sleeves 308 move within the adjustment cavity 302. The vertical support rod 309 fixed to the upper end of the threaded sleeve 308 drives the transverse support rod 310 to move. The blood vessel clamping arc plate 311 mounted on the side of the transverse support rod 310 clamps and secures the blood vessel. A through-slot 312 extending through the center of the protective block 304 and a transverse inner through-slot 313 provided therein provide space for accommodating and protecting the blood vessel.

[0038] Example 2

[0039] On the basis of Example 1, Figure 1 and Figure 8 As shown, the lifting platform 5 includes a support frame plate 501, a servo motor 507 is installed at the center of the upper end of the support frame plate 501, a threaded rotating rod 502 is installed at the output end of the servo motor 507, a second bearing 503 is installed at the lower end of the threaded rotating rod 502, and a lifting sleeve 504 is threadedly connected to the outer side of the threaded rotating rod 502;

[0040] The second bearing 503 is a deep groove ball bearing that can withstand radial and certain axial loads. It provides stable support for the threaded rotating rod 502, reduces shaking and friction resistance of the rotating rod during rotation, and enables the rotating rod to rotate more smoothly.

[0041] The lifting sleeve 504 has an internal threaded hole that matches the threaded rotating rod 502. The lifting movement is achieved through the threaded fit. The inner wall of the lifting sleeve 504 is finely processed to maintain an appropriate gap with the threaded rotating rod 502, which not only ensures smooth transmission but also prevents shaking caused by excessive gap.

[0042] The lifting sleeve 504 is provided with guide vertical rods 505 at both ends of the outer side of the threaded rotating rod 502, and the side end of the lifting sleeve 504 is installed with an adjustable mounting bracket 506 connected to the high-definition microscope 6;

[0043] The adjustable mounting bracket 506 is connected to the lifting sleeve 504 by high-strength bolts, and the connection is designed with an anti-loosening structure to ensure that it will not loosen due to factors such as vibration during the operation. At the same time, the surface of the adjustable mounting bracket 506 is anti-slip and anti-corrosion treated, which is convenient for doctors to grasp and adjust during the operation, and can adapt to the disinfection environment of the operating room, which is convenient for postoperative cleaning and maintenance.

[0044] When the position of the high-definition microscope 6 needs to be adjusted, the servo motor 507 is started to drive the threaded rotating rod 502 to rotate, so that the lifting sleeve 504 connected to the outer thread of the threaded rotating rod 502 moves up and down under the action of the thread;

[0045] The lifting sleeve 504 is provided with guide vertical rods 505 at both ends of the outer side of the threaded rotating rod 502 to ensure the stability of the movement of the lifting sleeve 504. The adjustable mounting bracket 506 connected to the high-definition microscope 6 is installed on the side end of the lifting sleeve 504 to drive the high-definition microscope 6 to move up and down, thereby realizing the height adjustment of the high-definition microscope 6.
