Description

Technical Field

[0001] This utility model relates to the field of minimally invasive surgical instruments, and more particularly to a flexible clamping device for minimally invasive surgery. Background Technology

[0002] With the advancement of modern medical technology, minimally invasive surgery has become increasingly popular in clinical applications due to its advantages such as less trauma and faster postoperative recovery. However, minimally invasive surgery places extremely high demands on the flexibility and precision of instruments, especially when clamping tissues to avoid damaging surrounding blood vessels or nerves. Currently widely used rigid clamping instruments have significant drawbacks: insufficient flexibility, as rigid structures cannot adapt to the complex and ever-changing surgical paths within the body, leading to limited operation and affecting the surgical field of vision and precision; risk of tissue damage, as rigid materials are prone to causing mechanical damage to surrounding tissues due to inaccurate force control during clamping, increasing the risk of postoperative complications; and weak repositioning ability, as traditional instruments lack elastic repositioning design, failing to quickly return to their initial shape after clamping, affecting the efficiency of continuous operation.

[0003] Therefore, there is an urgent need for a clamping device that combines flexible bending capability, precise force control, and efficient elastic repositioning to meet the pressing need for highly adaptable instruments in minimally invasive surgery. Utility Model Content

[0004] To address the aforementioned technical issues, a flexible clamping device for minimally invasive surgery is provided. This device utilizes a combination of a clamp handle, a flexible tube, and a clamp beak to achieve flexible bending and elastic repositioning, thereby reducing tissue damage.

[0005] To achieve the above objectives, this utility model provides a flexible clamping device for minimally invasive surgery, comprising: a clamp handle, a trigger rotatably mounted on the left side of the clamp handle, a fixing ring fixedly mounted on the upper left side of the clamp handle, a catheter fixedly mounted on the left side of the fixing ring, a flexible component disposed at the left end of the catheter, a clamp beak mounted on the left side of the flexible component, and a first flexible traction wire installed inside the clamp handle, the left and right ends of the first flexible traction wire being connected to the trigger and the clamp beak respectively, and the first flexible traction wire penetrating the interior of the flexible tube.

[0006] Furthermore, the flexible component includes a flexible tube fixedly installed between the left end of the catheter and the forceps beak. Multiple sets of first bending control rings and multiple sets of second bending control rings are provided inside the flexible tube. The first bending control rings and adjacent second bending control rings are fixedly connected by connecting blocks. The multiple sets of first bending control rings, second bending control rings and connecting blocks are all sleeved outside the first flexible body traction line. Multiple sets of second flexible body traction lines are arranged in a ring on the outer wall of the first bending control rings and second bending control rings. A control handle is installed on the upper right side of the forceps handle, and the multiple sets of second flexible body traction lines are connected to the control handle.

[0007] Furthermore, the clamp beak body is made of titanium alloy, and its jaw surface is covered with a medical-grade silicone layer.

[0008] Furthermore, the flexible tube includes multiple sets of external elastomers and a set of internal elastomers. The multiple sets of external elastomers are distributed on the outer wall of the flexible tube, and the internal elastomers are disposed at the contact points between the inner wall of the flexible tube and the first bending control ring and the second bending control ring.

[0009] Furthermore, the multiple sets of first and second bending control rings all adopt a segmented structure, and the connection points of adjacent segments of the first and second bending control rings are arranged in a cross shape.

[0010] Furthermore, a force sensor is embedded in the jaw surface of the clamping jaws.

[0011] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] 1. The present invention provides a flexible clamping device for minimally invasive surgery, which achieves multi-angle bending adjustment of the clamp beak through the cooperation of a segmented bending control ring and a second flexible body traction line, accurately matching narrow cavities and curved anatomical structures, and significantly reducing damage to surrounding tissues.

[0013] 2. The present invention provides a flexible clamping device for minimally invasive surgery. The flexible tube adopts a double-layer elastomer design to enhance the automatic reset capability after clamping. Combined with the medical silicone surface of the clamping beak and the force sensor, it monitors and buffers the clamping force in real time to avoid excessive pressure on the tissue.

[0014] 3. The present invention provides a flexible clamping device for minimally invasive surgery. The titanium alloy clamp beak ensures structural strength, and the flexible components have the characteristics of rapid reset, which shortens the operation interval time, reduces the risk of secondary damage to the patient by the instrument, and improves the success rate of minimally invasive surgery.

[0028] like Figures 1 to 4 As shown, this utility model provides a flexible clamping device for minimally invasive surgery, including a clamp handle 1, a trigger 2 rotatably mounted on the left side of the clamp handle 1, a fixing ring 3 fixedly mounted on the upper left side of the clamp handle 1, a catheter 4 fixedly mounted on the left side of the fixing ring 3, a flexible component provided at the left end of the catheter 4, a jaw 6 mounted on the left side of the flexible component, a first flexible body traction line 7 installed inside the clamp handle 1, the left and right ends of the first flexible body traction line 7 being connected to the trigger 2 and the jaw 6 respectively, and the first flexible body traction line 7 passing through the flexible tube 5.

[0029] During the surgery, by holding the forceps handle 1 and pulling the trigger 2, the forceps beak 6 is driven by the first flexible traction line 7 to clamp the patient's area. The flexible components allow for positional adjustment of the forceps beak 6, improving its flexibility during use. The forceps beak 6 is made entirely of titanium alloy, with the clamping surface made of medical-grade silicone. Titanium alloy possesses high strength and toughness while being lightweight, meeting the clamping requirements during surgery. Meanwhile, medical-grade silicone offers excellent biocompatibility and wear resistance, preventing secondary harm to the patient and enhancing surgical safety.

[0030] The flexible component includes a flexible tube 5, which is fixedly installed between the left end of the conduit 4 and the jaws 6. Multiple sets of first bending control rings 8 are installed inside the flexible tube 5, and multiple sets of second bending control rings 9 are installed inside the multiple sets of flexible tubes 5. A connecting block 10 is installed between each of the first bending control rings 8 and the multiple sets of second bending control rings 9. The multiple sets of first bending control rings 8, multiple sets of second bending control rings 9 and multiple sets of connecting blocks 10 are all sleeved on the first flexible body traction line 7. Multiple sets of second flexible body traction lines 11 are annularly installed on the outer wall of the multiple sets of first bending control rings 8 and multiple sets of second bending control rings 9. A control handle 12 is installed on the upper right side of each of the jaws 1, and the multiple sets of second flexible body traction lines 11 are connected to the control handle 12.

[0031] By moving the control handle 12, the flexible tube 5, multiple sets of first bending control rings 8, multiple sets of second bending control rings 9, and multiple sets of second flexible body traction lines 11 are bent, which can be flexibly bent and adjusted according to different surgical needs, so that the jaws 6 can better adapt to the complex and ever-changing surgical environment and reduce damage to surrounding tissues.

[0032] The flexible tube 5 includes multiple sets of external elastic bodies and a set of internal elastic bodies. The multiple sets of external elastic bodies are located on the outer wall of the flexible tube 5, and the internal elastic body is located on the inner wall of the flexible tube 5 at the point where it fits with multiple sets of first bending control rings 8 and second bending control rings 9.

[0033] The use of external and internal elastomers further enhances the elastic recovery capability of the flexible tube 5, enabling more stable control of force during clamping and avoiding excessive pressure on the tissue.

[0034] Multiple sets of first bending control rings 8 and multiple sets of second bending control rings 9 are arranged in a segmented manner, with the connection points of the multiple sets of first bending control rings 8 and multiple sets of second bending control rings 9 arranged in a cross shape.

Then, the trigger 2 is pulled, and the forceps beak 6 is driven by the first flexible traction line 7 to clamp the patient. The clamping force is monitored in real time by a force sensor to avoid putting excessive pressure on the patient. After the surgery is completed, the flexible tube 5, multiple sets of first bending control rings 8, multiple sets of second bending control rings 9, and multiple sets of second flexible traction lines 11 can automatically reset due to the setting of external and internal elastic bodies, making it easy to use next time.
