Description

Technical Field

[0001] The utility model relates to the technical field of soft tissue clamps, in particular to a traction device for a rotatable soft tissue clamp. Background Technique

[0002] A rotatable soft tissue clamp is a tool for clamping and fixing soft tissues in medical surgeries. It usually has the characteristic of being rotatable, allowing doctors to adjust the angle and position of the clamp according to the surgical needs. This kind of clamp can be opened and closed repeatedly, facilitating adjustment and operation during the surgery. The main function of the traction device of the soft tissue clamp in medical surgeries is to provide stable traction force, so that doctors can perform surgical operations more precisely. When performing endoscopic submucosal dissection (ESD) of the esophagus, stomach, and rectum, the soft tissue clamp cooperating with the traction device can help fully expose the submucosal layer, providing a wide operation space and a clearer operation direction.

[0003] Common soft tissue clamp traction devices perform traction by adding a figure-eight ring. However, this method may increase the friction of the system due to the figure-eight ring, which may affect the smoothness and efficiency of traction in soft tissue clamp traction. And if the figure-eight ring is not pulled to the verified position or the material is not ideal enough, it may slip when applying force, thus reducing the safety of traction. At the same time, due to the material limitation of the figure-eight ring, its cost is relatively high and cannot meet the working requirements of soft tissue clamp traction. For this reason, a traction device for a rotatable soft tissue clamp is proposed. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a traction device for a rotatable soft tissue clamp to solve the technical problem that the figure-eight ring may increase the friction of the system, which may affect the smoothness and efficiency of traction in soft tissue clamp traction.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solutions: A traction device for a rotatable soft tissue clamp, comprising:

[0008] A rotatable soft tissue clamp, a strap is sleeved on the outer side of the rotatable soft tissue clamp, and a traction wire is connected to the right side of the strap.

[0009] Preferably, a winding roller is installed at the right end of the traction wire, the right side of the traction wire is wound around the outside of the winding roller, and the right end of the traction wire is connected to the outside of the winding roller through a colloid. The traction wire can be wound by the winding roller, which facilitates adjusting the tension of the traction wire.

[0010] Preferably, both the left and right ends of the winding roller are connected with U-shaped frames through rotating shafts. A lead screw is connected through a ball bearing at a position above the winding roller inside the U-shaped frame. A guide rod is connected at a position above the lead screw inside the U-shaped frame.

[0011] Preferably, a slider is screwed on the outside of the lead screw. The guide rod penetrates through the upper side inside the slider. A through hole is opened inside the slider. The left end of the traction wire penetrates through the inside of the through hole. The added lead screw and guide rod facilitate the left and right movement of the slider.

[0012] Preferably, both the right ends of the winding roller and the lead screw penetrate through the corresponding positions of the U-shaped frame. A side plate is connected to the lower part on the right side of the U-shaped frame. A stepping motor is installed on the upper surface of the side plate. The rotor of the stepping motor is coaxially connected with a driving gear.

[0013] Preferably, the left side of the driving gear is coaxially connected with the right end of the winding roller. The right end of the lead screw is coaxially connected with a driven gear. The driven gear meshes with the driving gear. The number of turns of the driving gear can be controlled by the stepping motor. Thus, the rotation of the lead screw can be driven by the driven gear, so that while the winding roller controls the winding and unwinding of the traction wire, the left and right movement of the slider is driven. This not only facilitates the control of the tension degree of the traction wire, but also adjusts the magnitude of the traction force at the traction point through the number of turns of the winding roller.

Due to the flexible characteristics of the wire material, it can reduce the damage to soft tissues when applying traction force, especially in the case of requiring fine operations. Thus, the fluency and efficiency of traction are relatively high. And the wire traction can be carried out at different angles and directions, which provides a greater operation freedom for doctors and helps to accurately adjust the traction angle. At the same time, due to the friction force of the wire material and the characteristics of being softly tied, the problem of falling off during traction is avoided. And the wire material has a lower cost compared with the figure-eight ring during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present utility model provides a technical solution, a traction device for a rotatable soft tissue clamp, including a rotatable soft tissue clamp 1, a strap 2, a traction line 3, a winding roller 4, a U-shaped frame 5, a lead screw 6, a slider 7, a guide rod 8, a side plate 9, a stepper motor 10, a driving gear 11, a driven gear 12 and a through hole 13:

[0023] Please refer to Figure 1 , a strap 2 is sleeved outside the rotatable soft tissue clamp 1, and a traction line 3 is connected to the right side of the strap 2. The traction line 3 added by the strap 2 replaces the traditional figure-eight ring for traction. Due to the flexible characteristics of the wire, it can reduce the damage to soft tissues when applying traction force, especially in cases where fine operations are required, thus making the traction smooth and efficient. Moreover, wire traction can be carried out at different angles and directions, which provides greater operating freedom for doctors and helps to accurately adjust the traction angle. At the same time, due to the friction of the wire and its soft binding characteristics, the problem of falling off during traction is avoided, and the wire is lower in cost than the figure-eight ring during use;

Please refer to Figure 3 , a through hole 13 is opened inside the slider 7, and the left end of the traction line 3 passes through the inside of the through hole 13. Please refer toFigure 2 , the right ends of the coiling roller 4 and the lead screw 6 both penetrate through the corresponding positions of the U-shaped frame 5.

The rotor of the stepping motor 10 is coaxially connected to a driving gear 11. The left side of the driving gear 11 is coaxially connected to the right end of the coiling roller 4. The right end of the lead screw 6 is coaxially connected to a driven gear 12, and the driven gear 12 meshes with the driving gear 11. The number of turns of the driving gear 11 can be controlled by the stepping motor 10, so that the lead screw 6 can be driven to rotate through the driven gear 12, so that while the coiling roller 4 controls the winding and unwinding of the traction wire 3, the left and right movement of the slider 7 is driven. This not only facilitates the control of the tension of the traction wire 3, but also adjusts the magnitude of the force at the traction point by the number of turns of the coiling roller 4.

Moreover, the wire material traction can be carried out at different angles and directions, which provides greater operation freedom for doctors and helps to accurately adjust the traction angle.

In addition, the wire material has a lower cost than the figure-eight loop during use. At the same time, the number of turns of the driving gear 11 can be controlled by the stepping motor 10, so that the lead screw 6 can be driven to rotate through the driven gear 12, so that while the coiling roller 4 controls the winding and unwinding of the traction wire 3, the left and right movement of the slider 7 is driven. This not only facilitates the control of the tension of the traction wire 3, but also adjusts the magnitude of the force at the traction point by the number of turns of the coiling roller 4. Compared with the method of pulling the traction wire 3 by hand for traction, it reduces the operation fatigue, and ensures the consistency and accuracy of each traction, improving the quality of treatment and the smoothness of the progress.
