Description

Technical Field

[0001] This invention belongs to the field of surgical instrument technology, specifically a surgical retraction expander for deep tissues in small incisions. Background Technology

[0002] In clinical surgical treatment of patients, when medical personnel perform internal surgical procedures, they need to make an incision on the patient's surface and then use a medical retractor to pull the incision open, so that a certain area of ​​vision is formed at the wound site in order to operate on the internal surgical site.

[0003] Currently, traditional surgical retractors are usually pulled by hand by medical staff, which is time-consuming and laborious. Sometimes, multiple surgical retractors are needed during surgery, requiring multiple people to pull them, wasting a lot of manpower. Sometimes, when the surgical field of view is small and the incision is small, multiple surgical retractors are also needed to open the incision, which is very inconvenient. Because surgical retractors can cause a small amount of bleeding when they compress the wound, the oozing blood can cover the surgical field of view and cause some interference to the surgery. Medical staff also have to handle the blood separately, making the operation complicated. Summary of the Invention

[0041] The telescopic tube has its outer wall slidably connected to the inner wall of the fixed tube.

[0042] Cotton block, which is disposed on the inner wall of the irregular tube.

[0043] The beneficial effects of this invention are as follows:

[0044] 1. This invention, by setting up a retraction mechanism, allows the end of the expansion component to contact the patient's incision. The width of the expansion component is determined according to the size of the patient's incision, making it suitable for various types of surgeries. The size of the contact position with the incision can be flexibly controlled according to the incision length. Compared with manual operation, using mechanical means to maintain expansion is more convenient and stable, reducing the number of medical staff required.

[0045] 2. This invention, by setting up a blood-cleansing mechanism, allows the doctor to press a squeezing pump during surgery when blood flows at the incision site after the incision has been expanded and fixed. This pump expands and generates negative pressure, drawing the flowing blood into the storage component, thus preventing blood from covering the incision and affecting the doctor's observation. The operation is simple, and when manpower is insufficient, it can be operated with one hand to quickly remove small amounts of flowing blood. If necessary, the blood-cleansing component can be removed.

[0046] 3. This invention, by setting up an expansion component, places the traction hooks vertically upwards. When the incision is large, all three traction hooks need to be used. The cotton sleeves outside the traction hooks remain in contact with the incision. When a small amount of blood flows out of the incision, it is directly absorbed by the cotton sleeves. After use, the cotton sleeves are removed and discarded, and the traction hooks and equipment are thoroughly disinfected. It can be reused multiple times, which can flexibly cope with the use of different incisions and can also absorb the small amount of blood flowing out of the incision, reducing the doctor's attention to the incision site and improving surgical efficiency.

[0047] 4. This invention, by setting up a storage component, generates negative pressure when blood flows at the incision site. The doctor holds the telescopic tube close to the incision to absorb the blood. The blood passes through the telescopic tube into the fixed tube and is finally absorbed by the cotton block inside the irregular tube. When the cotton block at the bottom has absorbed a large amount, the doctor presses the telescopic tube inward, causing the top of the telescopic tube to move upward relative to the cotton block, so that the absorbed blood is absorbed by the upper layer of cotton block, preventing blood backflow. This facilitates one-handed operation and can play an emergency role in sudden situations. Attached Figure Description

The retraction mechanism 4 is adjusted according to the size of the surgical incision so that the incision mechanism contacts the incision and continues to expand outward. The blood at the incision is suctioned away by the blood cleaning mechanism 5, so that medical staff do not need to manually expand the incision, maintain a consistent force for expanding the incision, and select the size of the retraction mechanism 4 that contacts the incision according to the size of the incision. It is suitable for various types of surgery.

[0068] The fourth tractor includes:

[0069] Flexible bracket 401 is installed on top of mounting block 2;

[0070] Support rod 404 is installed at the end of flexible support 401;

[0071] Expansion assembly 403 is installed at the end of support rod 404 away from flexible support 401;

[0072] The movable component 402 is disposed on top of the mounting block 2, and the top of the movable component 402 is movably connected to the outer wall of the support rod 404.

[0073] After adjusting the height of the fixing mechanism 1 and the distance of the expansion ring 3, medical staff manually bend the flexible support 401 so that the support rod 404 drives the expansion component 403 to a suitable angle. Then, the expansion component 403 slides along the moving component 402, moves to a suitable position during the incision and expansion process, and is fixed and held still. The end of the expansion component 403 contacts the patient's incision. The width of the expansion component 403 is determined according to the size of the patient's incision. It is suitable for various types of surgery. The size of the contact position with the incision can be flexibly controlled according to the incision length. Compared with manual operation, using mechanical means to maintain expansion is more convenient and stable, and reduces the number of medical staff required.

The distance between the two expansion rings 3 is fixed as needed by the locking buckle 7 and the extension rod 6, and the telescopic rod 101 provides a suitable height to flexibly meet the surgeon's needs.

[0078] Blood purification facility 5 includes:

[0079] Fixing plate 501 is installed in the middle of expansion ring 3;

[0080] The squeeze pump 502 is installed on the top of the fixed plate 501. The squeeze pump 502 is an airbag with a large elasticity. A one-way valve is provided on the top of the squeeze pump 502.

[0081] Blood purification facility 5 also includes:

[0082] Air pipe 503 is installed at the bottom of the extrusion pump 502, and the outer wall of air pipe 503 is sleeved with the inner wall of fixing plate 501.

[0083] Storage component 504 is disposed at the bottom of trachea 503.

[0084] The trachea 503 is a flexible rigid tube that can support the telescopic component. It is located near the incision. After the incision is expanded and fixed, when blood flows at the incision during the operation, the doctor presses the squeeze pump 502 to expand it and generate negative pressure, drawing the flowing blood into the storage component 504. This prevents blood from covering the incision and affecting the doctor's observation. The operation is simple and can be performed with one hand when there is a shortage of manpower. The small amount of flowing blood can be quickly suctioned away. If necessary, the blood-cleansing component can be removed.

[0085] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the moving component 402 includes:

[0086] The movable frame 4021 is rotatably connected to the outer wall of the support rod 404.

[0087] Telescopic column 4022 is installed at the bottom of movable frame 4021;

[0088] Slide rod 4024 is set on top of mounting block 2;

[0089] The bottom of the movable block 4023 is slidably connected to the top of the slide bar 4024, and the top of the movable block 4023 is connected to the bottom of the telescopic column 4022.

[0090] The telescopic column 4022 is rotatably connected to the movable frame 4021, allowing the support rod 404 to rotate freely within the movable frame 4021 when the doctor adjusts the flexible support 401, thus adjusting the expansion component 403 to the appropriate position. At the same time, the slide rod 4024 and the moving block 4023 can be locked together to control the distance of incision retraction and keep it stationary, ensuring consistent force during expansion and avoiding secondary damage to the incision. The retraction distance can be adjusted according to the needs of different surgeries and incision sizes, making it widely applicable and highly flexible.

[0091] Expansion component 403 includes:

[0092] Mounting rod 4031 is located at the end of support rod 404 away from flexible bracket 401, and the outer wall of mounting rod 4031 is uniformly provided with sliding grooves 4032.

[0093] The slide 4033 is evenly distributed on the inner wall of the slide groove 4032, and the inner wall of the slide 4033 is slidably connected to the outer wall of the slide groove 4032.

[0094] Expansion component 403 also includes:

[0095] Hook 4034 is installed on the outer wall of carriage 4033;

[0096] Cotton cover 4035 is installed on the outer wall of hook 4034. Cotton cover 4035 is made of absorbent material and is removable.

[0097] After the incision is made, the number of single-sided retraction hooks 4034 is adjusted according to the size of the incision. For small incisions, only one middle retraction hook 4034 is needed. In this case, the other two retraction hooks 4034 are bent upwards and placed vertically upwards through the connection between the slide 4033 and the sliding groove 4032 on the mounting rod 4031. When the incision is larger, all three retraction hooks 4034 need to be used. The cotton sleeve 4035 outside the retraction hook 4034 keeps in contact with the incision. When a small amount of blood flows out of the incision, it is directly absorbed by the cotton sleeve 4035. After use, the cotton sleeve 4035 is removed and discarded. The retraction hooks 4034 and the equipment are thoroughly disinfected. It can be reused multiple times, which can flexibly deal with the use of different incisions and absorb the small amount of blood flowing out of the incision, reducing the doctor's attention to the incision and improving surgical efficiency.

[0098] Storage component 504 includes:

[0099] The irregular tube 5041 is installed at the bottom of the trachea 503, and the bottom of the irregular tube 5041 is provided with a groove 5045.

[0100] Fixed tube 5043 is installed at the bottom of the irregular tube 5041.

[0101] Storage component 504 also includes:

[0102] The telescopic tube 5044 has its outer wall slidably connected to the inner wall of the fixed tube 5043;

[0103] Cotton block 5042 is placed on the inner wall of the irregular tube 5041.

[0104] Initially, the fixed tube 5043 is placed close to the incision, and the telescopic tube 5044 is pulled out to its maximum length. When blood flows at the incision, the squeeze pump 502 generates negative pressure. The doctor holds the telescopic tube 5044 close to the incision to draw in the blood. The blood passes through the telescopic tube 5044 and enters the fixed tube 5043, and is finally absorbed by the cotton pad 5042 in the irregular tube 5041. When the cotton pad 5042 at the bottom has absorbed a large amount, the doctor presses the telescopic tube 5044 inward, causing the top of the telescopic tube 5044 to move upward relative to the cotton pad 5042, so that the drawn-in blood is absorbed by the upper cotton pad 5042, preventing blood backflow. This facilitates one-handed operation and can play an emergency role in sudden situations.

[0105] The specific workflow is as follows:

[0106] During operation, the adjustment frame 102 is secured to the edge of the operating table, and the adjustment frame 102 is tightened by the handle 103. The adjustment frame 102 is rotatably connected to the telescopic rod 101. The distance between the expansion rings 3 is controlled according to the patient's body shape or the needs of the surgery. The expansion ring 3 consists of two arc-shaped rods. One expansion ring 3 is connected to the extension rod 6, and the other expansion ring 3 is connected to the locking buckle 7. The distance between the two expansion rings 3 is fixed as needed by the locking buckle 7 and the extension rod 6, and the telescopic rod 101 provides a suitable height to flexibly meet the surgeon's needs.

[0107] Medical staff manually bend the flexible stent 401 so that the support rod 404 drives the expansion component 403 to a suitable angle. Then the expansion component 403 slides along the moving component 402 and moves to a suitable position during the incision and expansion process before being fixed and kept still. The end of the expansion component 403 contacts the patient's incision. After the incision is made, the number of unilateral traction hooks 4034 is adjusted according to the size of the incision.

[0108] For small incisions, only one middle hook 4034 is needed. The other two hooks 4034 are then bent upwards and placed vertically upwards through the connection between the slide 4033 and the slide groove 4032 on the mounting rod 4031. When the incision is larger, all three hooks 4034 need to be used. The cotton sleeve 4035 outside the hook 4034 keeps in contact with the incision. When a small amount of blood flows out of the incision, it is directly absorbed by the cotton sleeve 4035. After use, the cotton sleeve 4035 is removed and discarded. The hooks 4034 and the equipment are then thoroughly disinfected. The device can be reused multiple times, which can flexibly deal with different incisions and absorb the small amount of blood flowing out of the incision.

[0109] During the surgery, when blood flows at the incision site, the doctor presses the squeeze pump 502 to expand it and create negative pressure. The doctor holds the telescopic tube 5044 close to the incision to absorb the blood. The blood passes through the telescopic tube 5044 into the fixed tube 5043, and is finally absorbed by the cotton pad 5042 in the irregular tube 5041. When the cotton pad 5042 at the bottom has absorbed a large amount, the doctor presses the telescopic tube 5044 inward, causing the top of the telescopic tube 5044 to move upward relative to the cotton pad 5042, so that the absorbed blood is absorbed by the upper cotton pad 5042, preventing blood backflow. This facilitates one-handed operation and can play an emergency role in sudden situations. If necessary, the blood-cleansing component can be removed.
