[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Example 1
[0025] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an integrated surgical retractor with adjustable spacing, comprising an adjusting plate 1, a groove is provided on the surface of the adjusting plate 1, and the groove provided on the surface of the adjusting plate 1 is adapted to the size of the bolt rod 5, one end of the adjusting plate 1 is fixedly connected to a connecting plate 2, the middle parts of the adjusting plate 1 and the connecting plate 2 are fixedly connected, so that the adjusting plate 1 and the connecting plate 2 are connected as a whole, a retractor plate 3 is provided on the surface of the adjusting plate 1, a circular hole is provided on the surface of the retractor plate 3, and one end of the bolt rod 5 passes through the circular hole provided on the surface of the retractor plate 3, so that the circular hole in the middle part of the retractor plate 3 can pass through to the surface of the bolt rod 5, one end of the retractor plate 3 is fixedly connected to a small curved hook 31, and the end of the retractor plate 3 away from the small curved hook 31 is fixedly connected to a large curved hook 32, the size of the large curved hook 32 is larger than the size of the small curved hook 31, and the surfaces of the small curved hook 31 and the large curved hook 32 are both provided with concave and convex grooves.
[0026] In this embodiment, the width of the large hook 32 is significantly greater than that of the small hook 31. Since the liver is the largest gland in the human body and has a large volume, but the gallbladder is small, when performing liver and gallbladder surgery, the design of the small hook 31 and the large hook 32 is applicable to organs of different sizes, and the edges of the concave and convex grooves on the inner walls of the small hook 31 and the large hook 32 are smooth, which increases the friction with the surface of the organ and prevents it from falling off during the pulling process. At the same time, the smooth edges of the concave and convex grooves reduce damage to the surface of the organ.
[0027] Example 2
[0028] like Figure 1-Figure 4 As shown, a bottom plate 4 is provided at the bottom of the adjusting plate 1, and a bolt rod 5 is fixedly connected to the surface of the bottom plate 4. A thread is provided at the top of the bolt rod 5, and the bottom surface of the bolt rod 5 is set to a smooth surface. The thread provided at the top of the bolt rod 5 is convenient for connection with the clamping block 7. At the same time, a smooth surface is provided at the bottom end of the bolt rod 5 to reduce the friction between the adjusting plate 1, and a fixing block 6 is fixedly connected to the top of the bolt rod 5. A clamping block 7 is provided on the surface of the bolt rod 5. A thread groove is provided on the inner wall of the clamping block 7, and the thread groove provided on the inner wall of the clamping block 7 is adapted to the thread provided on the top of the bolt rod 5, so that the top of the bolt rod 5 and the inner wall of the clamping block 7 are threadedly connected, which can control the tightness between the hook plate 3 and the adjusting plate 1, and facilitate the adjustment of the position of the hook plate 3.
[0029] In this embodiment, the diameter of the fixed block 6 is greater than the diameter of the clamping block 7. Since the size of the clamping block 7 is relatively small, the design of the fixed block 6 prevents the clamping block 7 from shaking and falling off the surface of the bolt rod 5 during long-term use of the hook plate 3. The fixed block 6 plays a certain limiting role on the clamping block 7.
[0030] Working principle:
[0031] like Figure 1-Figure 4 As shown, by designing structures such as the adjusting plate 1 and the bolt rod 5, the surface of the bolt rod 5 is slid into the groove opened on the surface of the adjusting plate 1 along the notches opened on both sides between the adjusting plate 1 and the connecting plate 2, and the end of the bolt rod 5 fixedly connected to the fixing block 6 is facing upward, and the bolt rod 5 is embedded in the groove opened on the surface of the designated adjusting plate 1, and the block 7 is rotated counterclockwise, and the block 7 gradually moves downward along the thread on the surface of the bolt rod 5, so that the surfaces of the hook plate 3 and the adjusting plate 1 are tightly attached. When the surgical site needs to be re-expanded by the hook, the bolt rod 5 is inserted from the notch between the adjusting plate 1 and the connecting plate 2 on the other side, and then the bolt rod 5 is moved to a suitable groove for rotation and fixation again, and the small curved hook 31 or the large curved hook 32 is placed on the patient's organ part, and the adjusting plate 1 and the connecting plate 2 are held by hand to pull several surgical hooks at the same time, exposing the hand part to the field of vision, and performing surgical operations on it.
[0032] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
