For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0029] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0030] Please see Figures 1 to 4 The minimally invasive surgical tissue traction device in the first embodiment of this utility model includes: a clamp 1, an elastic element 2, and a fixing component 3. The elastic element 2 is installed between the clamp 1 and the fixing component 3. Both the clamp 1 and the fixing component 3 are installed on the axis of the elastic element 2. The clamp 1 is provided with a first clamping surface 4 and a second clamping surface 5 to clamp human tissue in the middle. When the first clamping surface 4 and the second clamping surface 5 are in contact, they are parallel to each other. The fixing component 3 is provided with at least one stabilizing surface 6. The human tissue is expanded and stretched by gravity and / or friction through the elastic element 2 and the clamp 1.

[0031] This application utilizes a clamp 1 with a first clamping surface 4 and a second clamping surface 5 to hold human tissue in the middle. The first clamping surface 4 and the second clamping surface 5 are parallel to each other when in contact. By using the first clamping surface 4 and the second clamping surface 5 to clamp the patient's human tissue, the overall volume of the clamp 1 can be reduced. The patient's human tissue can be clamped by the cooperation of the first clamping surface 4 and the second clamping surface 5. Therefore, the structure is simple, the operation is convenient, the manufacturing cost is reduced, it is easy to clamp the clamp 1 onto the patient's human tissue, saving adjustment and installation time, avoiding the waste of surgical time, improving the efficiency of surgery, and facilitating the doctor's surgical operation.

[0032] When the first clamping surface 4 and the second clamping surface 5 are in contact, they are parallel to each other, which can provide a more stable clamping force. When human tissue is clamped between the first clamping surface 4 and the second clamping surface 5, the entire first clamping surface 4 or the second clamping surface 5 will always be in contact with the human tissue, which plays a role in lifting and increasing friction, thereby improving the clamping firmness, avoiding detachment and affecting the surgical effect, improving the success rate of the surgery, and also relieving the pressure on the patient's human tissue by increasing the contact area, thereby reducing the damage of the clamp 1 to the patient's human tissue and improving the patient's comfort during use.

[0033] The elastic element 2 is installed between the clamp 1 and the fixing component 3. The fixing component 3 has at least one stabilizing surface 6. Gravity and / or friction are used to expand and stretch the human tissue through the elastic element 2 and the clamp 1. The elastic element 2 provides a certain cushioning effect. When the fixing component 3 and the clamp 1 are used to pull the patient's human tissue, the elastic element 2 prevents the pulling force generated by the fixing component 3 from directly acting on the human tissue, avoiding excessive pulling. This ensures that the traction device achieves an effective pulling effect without causing serious damage to the human tissue, further reducing patient pain during use. It also provides some protection for the patient when adjusting the traction intensity. The fixing component 3 itself has a certain weight, allowing it to hang naturally in the air after the clamp 1 is held on the human tissue. Gravity forms the traction force of the clamp 1 on the human tissue, saving space in minimally invasive surgery and making the operation more convenient. The fixing component 3 can also be placed on the operating platform of minimally invasive surgery according to the stabilizing surface 6. The friction between the stabilizing surface 6 and the operating platform generates the traction force of the clamp 1 on the human tissue. By adjusting the distance between the fixing component 3 and the clamp 1, the traction force of the clamp 1 on the human tissue can be adjusted, which makes it easier to adjust the traction force, making the adjustment more convenient and labor-saving, reducing the time occupied in minimally invasive surgery, and improving the efficiency of minimally invasive surgery.

[0034] Please see Figures 1 to 4In some embodiments, a first isolation pad 11 and a second isolation pad 12 are detachably installed on the first clamping surface 4 and the second clamping surface 5, respectively.

[0035] This application features a first isolation pad 11 and a second isolation pad 12 detachably mounted on the first clamping surface 4 and the second clamping surface 5, respectively. The first isolation pad 11 and the second isolation pad 12 come into contact with the human tissue, further protecting the clamped tissue. Since the first isolation pad 11 and the second isolation pad 12 are detachably mounted on the first clamping surface 4 and the second clamping surface 5, they can be replaced after each patient's use, thus avoiding cross-infection during minimally invasive surgery, improving patient protection, and facilitating the cleaning and disinfection of the traction device after use.

[0036] The first isolation pad 11 and the second isolation pad 12 can be completely fitted onto the first clamping surface 4 and the second clamping surface 5, respectively, thereby improving the connection strength with the first clamping surface 4 and the second clamping surface 5, preventing them from falling off, and making it easier to clean and disinfect the puller.

[0037] Please see Figures 1 to 4 In some embodiments, the first isolation pad 11 and the second isolation pad 12 are both glued to the first clamping surface 4 and the second clamping surface 5.

[0038] In this application, both the first isolation pad 11 and the second isolation pad 12 are glued to the first clamping surface 4 and the second clamping surface 5. This glued installation method minimizes the distance between the first and second isolation pads 11 and 12 and the first and second clamping surfaces 4 and 5, thereby reducing the overall size of the puller. The glued first and second isolation pads 11 and 12 are also easier to install and remove from the first and second clamping surfaces 4 and 5, improving the efficiency of replacing the first and second isolation pads 11 and 12 and simplifying operation.

[0039] Please see Figures 1 to 4 In some embodiments, the second isolation pad 12 is provided with a plurality of anti-slip grooves 13, and the first isolation pad 11 is provided with a plurality of protrusions 14 corresponding to the anti-slip grooves 13.

[0040] This application features a second isolation pad 12 with multiple anti-slip grooves 13 and a first isolation pad 11 with multiple protrusions 14 corresponding to the anti-slip grooves 13. The anti-slip grooves 13 increase the friction between the second isolation pad 12 and the human tissue, making the connection between the clamped human tissue and the clamp 1 more secure and less prone to detachment, thus improving the safety and success rate of minimally invasive surgery. The multiple protrusions 14 on the first isolation pad 11, corresponding to the anti-slip grooves 13, work together with the anti-slip grooves 13 to more firmly hold the human tissue in place when the first clamping surface 4 and the second clamping surface 5 clamp the human tissue, further preventing the clamp 1 from detaching from the human tissue during minimally invasive surgery, thus improving the safety and success rate of minimally invasive surgery.

[0041] Please see Figures 1 to 5 In some embodiments, the elastic element 2 is an elastic rope, a spring, or a spring plate.

[0042] This application utilizes elastic element 2 as an elastic cord, spring, or spring plate. As an elastic cord, elastic element 2 facilitates storage, allowing it to be wound around clip 1, saving space after storage. As a spring, elastic element 2 offers better elasticity, effectively absorbing the pulling force acting on human tissue, alleviating patient pain, improving comfort, and facilitating adjustment of the pulling force. As a spring plate, the connection between elastic element 2 and clip 1 and fixing component 3 is more stable and secure, resulting in a longer service life, easier cleaning and sterilization, and reduced risk of bacterial infection during minimally invasive surgery.

[0043] Please see Figures 1 to 3 In some embodiments, the clamp 1 includes a first clamping frame 101, a second clamping frame 102, and a torsion spring 103. The first clamping frame 101 is rotatably connected to the second clamping frame 102, and the torsion spring 103 is installed between the first clamping frame 101 and the second clamping frame 102 to provide clamping force between the first clamping frame 101 and the second clamping frame 102.

[0044] This application utilizes a torsion spring 103 installed between the first clamping frame 101 and the second clamping frame 102 to provide clamping force between them. The tail ends of the first and second clamping frames 101 and 102 overcome the elastic force of the torsion spring 103, causing them to expand outwards. After placing the first clamping surface 4 and the second clamping surface 5 at the desired clamping position, releasing the tail ends of the first and second clamping frames 101 and 102 allows the elastic force generated by the torsion spring to clamp the first clamping surface 4 and the second clamping surface 5 onto the human tissue, facilitating clamping operations and improving the efficiency of minimally invasive surgery. The elastic force of the torsion spring 103 ensures that the first clamping surface 4 and the second clamping surface 5 consistently exert clamping force on the central human tissue, resulting in a more secure clamping during minimally invasive surgery, reducing the risk of detachment and improving safety and surgical success rate.

[0045] Please see Figures 1 to 4 In some embodiments, both the first clamping frame 101 and the second clamping frame 102 include: a clamping plate 110 and a connecting seat 120. The clamping plate 110 includes a clamping portion 111 forming a first clamping surface 4 or a second clamping surface 5, and an operating portion 112 extending away from the torsion spring 103. The connecting seat 120 is disposed on the operating portion 112, and the clamping portion 111 and the operating portion 112 are integrally formed.

[0046] This application utilizes a clamping plate 110 comprising a clamping portion 111 forming a first clamping surface 4 or a second clamping surface 5, and an operating portion 112 extending away from the torsion spring 103. The operating portion 112 extends away from the torsion spring 103, causing the tail end of the clamping plate 110 to expand outwards. This facilitates the effortless overcoming of the spring force of the torsion spring 103 by the operating portion 112, allowing the first clamping surface 4 and the second clamping surface 5 to open. The clamping portion 111 provides space for the formation of the first clamping surface 4 or the second clamping surface 5, enabling a tighter clamping force between the two surfaces, increasing the clamping force between intermediate human tissues, and further preventing dislodgement during minimally invasive surgery. The clamping portion 111 and the operating portion 112 are integrally formed, facilitating manufacturing and providing greater connection strength, thus extending their service life. The connecting seat 120 is set on the operating part 112. Then, the two connecting seats 120 and the torsion spring are passed through by the pin. During the cleaning and disinfection process, the first clamp 101 and the second clamp 102 will be separated simply by pulling out the pin. This makes it easier to clean and disinfect them after minimally invasive surgery, avoid bacterial residue, and further reduce the risk of bacterial infection during minimally invasive surgery.

[0047] Please see Figures 1 to 3In some embodiments, one end of the elastic member 2 is rotatably connected to the first clamping frame 101 or the second clamping frame 102.

[0048] This application utilizes an elastic element 2, one end of which is rotatably connected to either the first clamping frame 101 or the second clamping frame 102. By rotating the elastic element 2, the direction of the pulling force exerted on the clamping frame 1 by the fixation component 3 through the elastic element 2 can be changed when the clamping frame 1 is held on human tissue. This allows for wider applicability in various environments, facilitates adjustment of the direction of pulling on human tissue, reduces damage to the patient during adjustment, makes adjustment more effortless and convenient, improves adjustment efficiency, and reduces unnecessary operation time during minimally invasive surgery.

[0049] Please see Figure 5 and Figure 6 In some embodiments, the fixing component 3 is detachably mounted on the elastic member 2.

[0050] This application allows the fixing component 3 to be detachably installed on the elastic element 2. The fixing component 3 can be installed on the elastic element 2 by bolts. During cleaning and disinfection, the fixing component 3 and the elastic element 2 can be disassembled for separate cleaning and disinfection, which improves the efficiency of cleaning and disinfection. Depending on the elasticity of different patients' human tissues, the fixing component 3 of different weights can be replaced on the elastic element 2, thereby expanding the scope of application and making the traction device applicable to more patients in minimally invasive surgery.

[0051] Please see Figure 6 In some embodiments, the fixing component 3 includes: a connector 301, a weight-adding component 302, and a locking component 303. The connector 301 is provided with a slot 304 for storing the elastic component 2. The locking component 303 is installed on the connector 301 through a threaded pair to clamp the elastic component 2 in the slot 304. The weight-adding component 302 is installed on the connector 301.

[0052] This application features a slot 304 on the connector 301 for storing the elastic element 2. A locking member 303 is installed on the connector 301 via a threaded pair, clamping the elastic element 2 in the slot 304. A weight-adding member 302 is installed on the connector 301. The threaded pair between the locking member 303 and the connector 301 clamps the elastic element 2 in the slot 304. This allows the position of the weight-adding member 302 on the elastic element 2 to be changed. The distance between the fixing component 3 and the clamp 1 can be adjusted according to the on-site usage environment, making it suitable for more minimally invasive surgical environments. It is easy to adjust and allows the weight-adding member 302 to be quickly removed from the elastic element 2 for cleaning and disinfection, facilitating operation.

[0053] Please see Figure 6 In some embodiments, the fixing component 3 further includes a protective sleeve 305 fitted onto the weight-adding component 302.

[0054] This application utilizes a protective sleeve 305, made of rubber, fitted onto the weight-adding component 302. This sleeve increases friction between the weight-adding component 302 and the operating platform, making the pulling force of the clamp 1 on the human tissue more stable during minimally invasive surgery, reducing its impact on the procedure and improving the success rate. The protective sleeve 305 also provides cushioning for the weight-adding component 302, preventing it from falling and injuring others, thus improving safety.

[0055] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
