Description

Technical Field

[0001] The present invention belongs to the technical field of instrument storage, and particularly relates to a towel clamp for feedback and pressing force for tibiofibular syndesmosis injury. Background Art

[0002] In the medical field, fractures are a common traumatic injury, and tibiofibular syndesmosis injury is a common fracture and joint injury of the lower limb, which requires accurate fracture reduction to promote normal fracture healing. Traditional fracture reduction methods mainly rely on the experience and manual operation of surgeons, and there are problems such as inaccurate reduction and large surgical trauma. Therefore, to solve these problems, towel clamps have emerged. The towel clamp can assist in achieving accurate fracture reduction under the operation of a doctor by applying appropriate force and pressure. It can provide stable force support for the doctor and guide the fracture ends back to the correct position through mechanical principles to promote fracture healing. And using a towel clamp for reduction operation is usually gentler than traditional manual methods, can reduce surgical trauma, and can improve the reduction success rate at the same time. The accuracy and stability of the towel clamp can help the doctor better control the reduction process and increase the success rate of reduction.

[0003] Although traditional towel clamps cannot apply a specific force and pressure to achieve accurate fracture reduction, traditional towel clamps do not have the function of feedback pressure, which will result in a relatively low accuracy rate of reduction. It may be necessary to continuously adjust the pressure to achieve accurate reduction, which increases the complexity of the doctor's operation and the patient's pain. And traditional towel clamps use a snap-fitting fixation form when fixing, which requires a high degree of fit for the towel clamp and is prone to detachment.

[0004] Therefore, a new towel clamp is needed, which has the function of feedback pressure. Doctors can accurately reduce the fracture point according to the feedback pressure, can improve the accuracy rate of accurate reduction, reduce the doctor's operation and relieve the patient's pain; and this towel clamp can have a new fixation method, which can make the towel clamp more firmly fixed and will not show the situation of detachment. Summary of the Invention

[0005] To solve the above technical problems, the present invention designs a towel clamp for feedback and pressing force for tibiofibular syndesmosis injury, including: a towel clamp main body, a locking mechanism, a pressure feedback mechanism, and a sleeve; the towel clamp main body is composed of two clamp arms and clamp claws connected by a rotating shaft, and the sleeve is arranged at the front end of the clamp claws of the towel clamp main body; the pressure feedback mechanism is fixedly connected to both ends of the clamp arms; the locking mechanism includes an adjusting component and a fixing strip, the adjusting component is fixedly installed on one clamp arm, and one end of the fixing strip is fixedly installed on the other clamp arm; the other end can movably pass through the adjusting component; the locking and relaxation of the fixing strip are controlled by the adjustment of the adjusting component to control the opening and closing of the towel clamp main body;

[0006] Furthermore, the adjustment includes a cam, a pressure block, a spring, and a locking head; the cam is provided with a toggle bar; the cam is located at the front end of the spring, one end of the spring is fixedly connected to the pressure block, and the other end is fixedly connected to the locking head;

Specific implementation mode

[0019] The present invention discloses a towel clamp with feedback and pressing force for syndesmosis injury, including: a towel clamp body 10, a locking mechanism 2, a pressure feedback mechanism 5, and a sleeve 9; the towel clamp body 10 is composed of two pliers arms 6 and pliers jaws 8 connected by a rotating shaft 7, and the sleeve 9 is arranged at the front ends of the two pliers jaws 8 of the towel clamp body 10; the pressure feedback mechanism 5 is fixedly connected to both ends of the pliers arm 6; the locking mechanism 2 includes an adjusting component and a fixed bar 3, the adjusting component is fixedly installed on one pliers arm 6, one end of the fixed bar 3 is fixedly installed on the other pliers arm 6; the other end can movably pass through the adjusting component; the locking and relaxation of the fixed bar 3 are controlled by the adjustment of the adjusting component to control the opening and closing of the towel clamp body 10;

[0020] Embodiment 1

[0021] In this embodiment, the adjustment component includes a cam 202, a pressure block 203, a spring 204, and a locking head 205; a toggle bar 201 is provided on the cam 202; the cam 202 is located at the front end of the spring 204, one end of the spring 204 is fixedly connected to the pressure block 203, and the other end is fixedly connected to the locking head 205; the specific principle process of the adjustment mechanism in this embodiment is: the position of the cam 202 is controlled by the toggle bar 201, and the cam 202 rotates counterclockwise. Due to the characteristics of the cam 202, when it rotates to a certain position, the cam 202 will press the pressure block 203, and the pressure block 203 is fixedly connected to the spring 204, so the pressure block 203 controls the expansion and contraction of the spring 204 and then controls the locking head 20 5 is extended and retracted to fix the fixing bar 3, and the fixing is completed under the cooperation of the locking head 205 and the groove 401 on the fixing bar 205; in this embodiment, the initial design is to set the toggle bar 201 on the rotation center of the cam 202 to control the rotation, but in actual use, it is found that if the toggle bar 201 is set on the rotation center of the cam 202, it will be difficult to control when rotating, and because the towel clamp is small and more precise, it is difficult to control it directly with fingers; therefore, the toggle bar 201 is set on one side of the cam 202, which is easier to control, and even if the finger cannot reach it, it can be gently toggled with tweezers or other surgical instruments, which makes up for the deficiency of setting the toggle bar 201 at the rotation center.

[0022] Example 2

[0023] In the present embodiment, the fixing bar 3 is a U-shaped structure, and an equidistant and continuous groove 401 is provided on the outer side, and the size of the groove 401 is adapted to the locking head 205. A limiting block 4 for limiting the fixing bar 3 is provided on the clamp arm 6 on one side of the adjustment component; the curvature radius of the fixing bar 3 is the same as the rotating shaft of the two clamp arms 6 and the clamp claw 8 connecting the towel clamp body 10, so that consistency can be maintained during use; the limiting block 4 is close to one side of the clamp arm 6, and the fixing bar 3 is limited by the setting of the limiting block 4 instead of the traditional "fixing box" to ensure that it will not fall off during fixing. The traditional "fixing box" may cause it to fall off during fixing when the towel clamps are misaligned with each other, but the fixing form of the towel clamp in the present invention can effectively avoid this situation.

[0024] Example 3

[0025] In this embodiment, the pressure feedback mechanism 5 includes a spring 204, a pressure sensor 502, and a display disk 503. The pressure sensor 502 is fixedly arranged inside the spring 204 and remains in contact with the spring 204. The display disk 503 is fixedly arranged on the surface of the forceps arm 6. Its working principle is as follows: When using the towel forceps for fixation, first, the towel forceps are clamped and fixed. When clamping and fixing, the doctor first applies pressure for resetting. The force applied by the doctor will be transmitted from the forceps arm 6 to the forceps jaw 8 due to the lever principle and then act on the tibia and fibula. At the same time, the tibia and fibula will generate the same force on the forceps jaw 8, which is then feedback to the forceps arm 6. At this time, since there is a pressure feedback mechanism 5 between the two forceps arms 6, the spring 204 in the pressure feedback mechanism 5 is compressed when receiving the force. The spring 204 conducts the force to the pressure sensor 502, and the pressure sensor 502 feeds back the signal to the display disk 503, and the display disk 503 immediately displays the pressure. The doctor can then adjust the fixation according to the feedback pressure. The pressure sensor 502 is a prior art and will not be elaborated further.

[0026] In this embodiment, another form of pressure feedback is provided, that is, the above-mentioned pressure sensor 502 is replaced with a simple dynamometer, and the display disk 503 is replaced with a mechanical display disk with a pointer on it. Under the action of pressure, the spring 204 is compressed, and at the same time, the pointer on the mechanical display disk rotates. The position pointed to by the pointer is the feedback pressure. This method has a lower accuracy compared to the pressure feedback by the pressure sensor 502. However, relatively speaking, there is no need to add the pressure sensor 502, and the pressure sensor 502 requires a circuit board and a battery, which will occupy a certain volume and is not so convenient to use. Therefore, using a mechanical dynamometer can be another preferred method in this embodiment.

[0027] Embodiment 4

[0028] In this embodiment, the diameter of the sleeve 9 is 2.5 mm, and the angle with the central axis of the towel forceps main body 10 is between 20° and 40°. And the towel forceps main body 10 is made of medical stainless steel or alloy material. A sleeve 9 is provided at the front end of the forceps jaw 8. The preferred angle of the angle between the sleeve 9 and the central axis of the towel forceps main body 10 is 30°. The sleeve 10 exists as a guide. When the towel forceps main body 10 is clamped and reset downward, the sleeve 9 follows and clamps downward. Since the sleeve 9 forms an angle of 30° with the central axis, when the forceps jaw 8 of the towel forceps is used, it will increase by 30° from the ground outward and inward, which is more conducive to fixation use.

[0029] The use process of the present invention is as follows: before using the towel clamp of the present invention, it is necessary to ensure that the patient is in an appropriate body position, such as lying or sitting, and clean the patient's skin to reduce the risk of infection; then the towel clamp of the present invention is used to clamp and reset. During the clamping and resetting, due to the presence of the sleeve, the angle can be increased by one level from the ground inward during operation; at the same time, the appropriate clamping force is adjusted according to the pressure value displayed on the adjustment disk fed back by the pressure feedback mechanism; after the adjustment and clamping are completed, the locking mechanism is used to lock, and when locking, the toggle rod is gently moved to insert the locking head into the groove on the fixing bar to complete the fixing.

[0030] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only the specific implementation methods described.
