Abstract
Description
TECHNICAL FIELD
[0001] The application relates to the technical field of clamping forceps, in particular to a circular stapler anvil head clamping forceps. BACKGROUND
[0002] In surgical operations, circular staplers are widely used in the anastomosis operation of digestive tract and other tissues. The accurate clamping and stable operation of the anvil head of the circular stapler are crucial for the success of the operation. Traditional clamping tools have many defects. On the one hand, the clamping angle of the traditional clamping forceps is usually fixed, which is difficult to meet the diverse needs of clamping angles in different operation scenes and the operation habits of different doctors. Doctors may need to twist their wrists or arms to adapt to the angle of the clamping forceps during use, which not only increases the difficulty and fatigue of operation, but also may affect the accuracy and stability of clamping, thereby adversely affecting the quality of the operation. On the other hand, the traditional clamping forceps lack effective locking mechanism after clamping the anvil head. During the operation process, the clamping forceps are easily loosened due to the collision of instruments, the inadvertent actions of doctors and other factors, which may cause the anvil head to shift, resulting in loose anastomosis, tissue damage and other serious surgical complications, increasing the risk of operation and the pain of patients.

[0016] The following will be described in detail in combination with the accompanying drawings Figures 1-3 The present application will be further described in detail.
[0017] The embodiment of the present application discloses a circular anastomat nail anvil head clamping forceps. Referring to Figures 1-3 A circular anastomat nail anvil head clamping forceps, comprising a clamping assembly 1, an adjustable handle 2, a limiting plate 3 and a bolt 4;
[0018] The clamping assembly 1 comprises two mutually hinged main rods 101, wherein the main rods 101 are made of medical stainless steel material, the straightness is ensured through a precision machining process, and a stable support frame is provided for the entire clamping action. The end of the main rod 101 is bent at an angle to form an arc, and the end is parallel to the main rod 101, which ensures good fit with the anvil head during clamping and improves the stability of clamping. The clamping groove 103 on the clamp head 102 is provided with anti-skid protrusions, which are achieved by machining fine lines or embedding rubber and other anti-skid materials in the groove. When clamping the anvil head, the friction can be effectively increased to prevent the anvil head from slipping off and ensure the accuracy and safety of the operation. The main rod 101 is provided with a clamp handle 104 with a rotating groove at the end away from the clamping groove 103.
[0019] Referring to Figure 1 The adjustable handle 2 comprises two handle grips 201, which are designed to conform to the shape of the human hand for holding, and are made of a composite structure of medical plastic or rubber wrapped around a metal core material, which not only ensures comfort during holding, but also has sufficient strength for easy operation by the doctor. The two handle grips 201 are each provided with a connecting disc 202.
[0020] Referring to Figure 3 The connecting disc 202 between the two handle grips 201 is connected to the clamp handle 104 by a bolt 4, which is a standard bolt made of medical stainless steel with high thread accuracy to ensure reliable connection. The side close to each other is provided with anti-skid measures, such as anti-skid ridges 5 that cooperate with each other. During use, the doctor can adjust the angle of the handle grip 201 relative to the main rod 101 by sliding the connecting disc 202 in the rotating groove of the clamp handle 104, and then tighten the bolt 4 to fix the handle grip 201 at the desired position, thereby adapting to different surgical scenarios and operation requirements and improving the accuracy of clamping.
[0021] Referring to Figure 2 The limiting plate 3 provides protection against accidental operation. The limiting plate 3 is made of a metal sheet, and the clamping groove is accurately machined. The clamping column 203 and the handle grip 201 are connected firmly by welding or one-piece forming process. When clamping is completed, the clamping column 203 is clamped into the clamping groove of the limiting plate 3 to lock the clamping position, effectively preventing the clamping forceps from loosening due to accidental operation during the operation, ensuring the smooth progress of the operation, and avoiding harm to the patient due to accidental loosening of the instrument.
[0022] The implementation principle of the circular anastomat anvil head clamping forceps according to the embodiment of the application is as follows:
[0023] Before the operation, the doctor first adjusts the angle of the handle 201 of the clamping forceps according to his own operation habits. Turn the connecting disc 202 in the rotating groove of the forceps handle 104 to the appropriate position, make the handle 201 form the most suitable angle relationship with the main rod 101 for his own operation, then pass the bolt 4 through the connecting hole of the connecting disc 202 and the forceps handle 104, tighten the bolt 4, make the connecting disc 202 and the forceps handle 104 relatively fixed, so as to lock the angle of the handle 201.
[0024] During the operation, when the circular anastomat anvil head needs to be clamped, the doctor holds the handle 201 with his hand and gradually applies pressure. Since the handle 201 is hinged with the main rod 101, the pressure is transmitted to the forceps head 102 through the main rod 101, so that the clamping groove 103 on the forceps head 102 gradually approaches and clamps the anvil head. The arc-shaped design of the bending of the forceps head 102 relative to the main rod 101 and the structure that the end is parallel to the main rod 101 make it better fit the shape of the anvil head when clamping the anvil head, increasing the stability and reliability of clamping. At the same time, the anti-skid protrusions inside the clamping groove 103 further enhance the friction between the anvil head and the clamping groove 103, preventing the anvil head from slipping or moving during clamping.
[0025] When the anvil head is successfully clamped, in order to prevent the clamping forceps from loosening due to accidental collision or the doctor's inadvertent action in subsequent operation, the clamping column 203 is clamped into the clamping groove of the limiting plate 3. Through this locking mechanism, even in the case of complex operation environment and frequent operation, the clamping forceps can always maintain stable clamping on the anvil head, providing a strong guarantee for the smooth progress of the operation and reducing the risk and complications caused by unstable clamping.
[0026] Finally, it should be pointed out that: first of all, in the description of the present application, it should be pointed out that unless otherwise specified and limited, the terms "installation", "connection", "connection" should be understood broadly, which can be mechanical connection or electrical connection, or the communication between two elements, or direct connection, "up", "down", "left", "right" and the like are only used to indicate the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;
[0027] Secondly: the utility model discloses the embodiment in the drawing, only relate to the structure involved in the embodiment of the present disclosure, other structures can refer to the usual design, in the case where there is no conflict, the same embodiment and different embodiments of the utility model can be combined with each other;
